    In this study, we demonstrated the remarkable genome plasticity of lytic lactococcal phages that allows them to rapidly adapt to the dynamic dairy environment. The lytic double-stranded DNA phage ul36 was used to sequentially infect a wild-type strain of Lactococcus lactis and two isogenic derivatives with genes encoding two phage resistance mechanisms, AbiK and AbiT. Four phage mutants resistant to one or both Abi mechanisms were isolated. Comparative analysis of their complete genomes, as well as morphological observations, revealed that phage ul36 extensively evolved by large-scale homologous and nonhomologous recombination events with the inducible prophage present in the host strain. One phage mutant exchanged as much as 79% of its genome compared to the core genome of ul36. Thus, natural phage defense mechanisms and prophage elements found in bacterial chromosomes contribute significantly to the evolution of the lytic phage population. PMID:17041060

    Embryo-fetal infections have been reported to cause recurrent spontaneous abortions (RSAs) at a rate lower than 4%. The possible mechanisms include production of toxic metabolic byproducts, fetal or placental infection, chronic endometrial infection, and chorio-amnionitis. Viruses appear to be the most frequently involved pathogens, since some of them can produce chronic or recurrent maternal infection. In particular, cytomegalovirus during pregnancy can reach the placenta by viremia, following both primary and recurrent infection, or by ascending route from the cervix, mostly following reactivation. Another herpesvirus, herpes simplex virus type 2, less frequently type 1, causes recurrent infections of the genital tract, which can involve the feto-placental unit. Parvoviruses have also been implicated in the development of repeated fetal loss. Among bacterial infections, Chlamydia trachomatis, Ureaplasma urealyticum,and Mycoplasma hominis have been mostly associated with occurrence of RSA. An increased risk of abortion among women with bacterial vaginosis (BV) during early pregnancy was also shown, but questions arise about the role of chronic BV in its occurrence. Although a definitive relationship between recurrently active infections and RSA is still lacking, mostly due to difficulties in demonstrating the pathogenic role of each individual isolated pathogen, diagnosis and therapy of RSA-related infections should be attempted. The diagnosis of infectious agents as a possible cause of RSA might lead to a therapeutic approach with antiviral drugs and antibiotics or using immunoglobulins, which can display both anti-infective neutralizing and immunomodulating properties.

    The dairy industry uses the mesophilic, Gram-positive, lactic acid bacterium (LAB) Lactococcus lactis to produce an array of fermented milk products. Milk fermentation processes are susceptible to contamination by virulent phages, but a plethora of phage control strategies are available. One of the most efficient is to use LAB strains carrying phage resistance systems such as abortive infection (Abi) mechanisms. Yet, the mode of action of most Abi systems remains poorly documented. Here, we shed further light on the antiviral activity of the lactococcal AbiT system. Twenty-eight AbiT-resistant phage mutants derived from the wild-type AbiT-sensitive lactococcal phages p2, bIL170, and P008 were isolated and characterized. Comparative genomic analyses identified three different genes that were mutated in these virulent AbiT-insensitive phage derivatives: e14 (bIL170 [e14(bIL170)]), orf41 (P008 [orf41(P008)]), and orf6 (p2 [orf6(p2)] and P008 [orf6(P008)]). The genes e14(bIL170) and orf41(P008) are part of the early-expressed genomic region, but bioinformatic analyses did not identify their putative function. orf6 is found in the phage morphogenesis module. Antibodies were raised against purified recombinant ORF6, and immunoelectron microscopy revealed that it is the major capsid protein (MCP). Coexpression in L. lactis of ORF6(p2) and ORF5(p2), a protease, led to the formation of procapsids. To our knowledge, AbiT is the first Abi system involving distinct phage genes. PMID:22820334

    1993-09-01

    Vacuum aspiration, dilatation and curettage, hysterotomy, and, in some cases, hysterectomy comprise surgical methods of abortion. Oral administration of RU-486, epostane, prostaglandins E and F2 and vaginal suppositories of prostaglandins E and F2 are medical abortion methods. The traditional or clandestine methods are usually performed by unqualified persons and pregnant women themselves. These methods tend to be inefficient and harmful. They include oral preparations of herbs and drugs (e.g., quinine and ergot), introduction of fluids (e.g., household disinfectants) into the vagina, introduction of foreign bodies (e.g., twigs, stems, hollow tubes, needles, wire) into the uterus. Hospital records, death certificates, and community-based surveys are common sources of data on abortion. Worldwide, 40-70/1000 women of childbearing age undergo an abortion. 20-33% of all pregnancies are terminated. Abortion is always legal when it is performed to save a pregnant woman's life. In most countries, it is legal to protect the woman's physical or mental health against serious danger. The risk of death from a legal abortion is rare. On the other hand, when an abortion is performed by an unqualified, unskilled abortionist and/or under unhygienic conditions (all of which are common in countries who have a law against abortion) the risk of death is much higher. In fact, abortion is one of the leading causes of maternal death in many countries (25% and 86% of maternal deaths in Bangladesh and Romania, respectively). Common complications of abortion are incomplete abortion, trauma to pelvic organs (e.g., uterine perforation), tetanus, and infertility. In some developing countries, the cost of treating abortion complications account for up to 50% of maternity hospital budgets. Ways to reduce mortality from unsafe abortion include promoting contraceptive use, legalizing abortion, allowing trained practitioners to perform abortions for health reasons, and improving clinical management

    Background: Chlamydia trachomatis is the etiology of most of sexually transmitted diseases. Colonization of C. trachomatis in the genital tract during early gestation has been associated with preterm birth, and preterm premature rupture of the membranes. The role of C. trachomatis on spontaneous abortion has not yet been proved completely. The aim of this study was to evaluate the frequency of C. trachomatis infection among pregnant women and its association with spontaneous abortion. Methods: This case-control study was conducted from August 2012 until January 2013. Totally, 218 women were included; 109 women with spontaneous abortion with gestation age between 10–20 weeks (cases), and 109 women with normal pregnancy with gestation age between 20–30 weeks (controls) in Sanandaj, Iran. DNA was extracted from endocervical swabs and a PCR test was conducted for detection of C. trachomatis infection in women using specific primers. Independent T-test and Chi-square were used for comparison of quantitative and qualitative variables, respectively, and p<0.05 was considered significant. Results: The total prevalence of C. trachomatis infection was 38(17.43%) in endocervical swabs of women. However, the number of cases with C. trachomatis infections was 25 out of 109(22.9%) in the case group and 13 out of 109(11.9%) in control group, respectively. Association between chlamydia infection and spontaneous abortion was statistically significant (OR=2.198, CI 95%: 1.058–4.56). Conclusion: Our study showed that C. trachomatis infection was associated with spontaneous abortion. Thus, screening and treatment of pregnant women may prevent this adverse pregnancy outcome.

    Herpes simplex virus strain MPdk− multiplies in HEp-2 cells, but not in dog kidney (DK) cells. Strain MPdk+sp, a multistep mutant of MPdk−, multiplies in both HEp-2 and DK cells. Stabilized lysates of productively infected cells yield three macromolecular aggregates of viral deoxyribonucleic acid and protein banding in CsCl gradients at densities of 1.285 g/cm3 (α), 1.325 g/cm3 (β), and 1.37 to 1.45 g/cm3 (γ). Similar lysates from abortively infected cells yield only the β and γ bands. Electron microscopic examination revealed that (i) the α band contained enveloped nucleocapsids, whereas the β band contained naked nucleocapsids and particles tentatively identified as internal components of the nucleocapsids, and that (ii) the enveloped virions and reduplication of cellular membranes observed in thin sections of productively infected cells were absent from abortively infected cells. Studies of the surface antigens of infected cells in a cytolytic system described previously revealed that abortively infected cells contained approximately 10-fold less virus-induced surface antigen than did productively infected cells. From these and other data published previously, we concluded that infectious MPdk− virions are not made in DK cells because (i) functional viral products necessary for the envelopment of the nucleocapsid are not made, and (ii) capsid proteins and some nonstructural products specified by the virus malfunction.

    During the 2002 and 2003 foaling seasons, Cellulosimicrobium (Cellumonas) cellulans (formerly Oerskovia xanthineolytica) was the principal microorganism isolated from fetal tissues or placentas from cases of equine abortion, premature birth, and term pregnancies. Significant pathologic findings included chronic placentitis and pyogranulomatous pneumonia. In addition, microscopic and macroscopic alterations in the allantochorion from 4 of 7 cases of placentitis were similar to those caused by Crossiella equi and other nocardioform bacteria. This report confirms a causative role of C. cellulans infection in equine abortion. PMID:15305747

    The historical and current (1969) abortion laws in France as well as those in other Western countries are analyzed. France has had a series of punitive abortion codes since the Napoleonic Code of 1810 prescribing solitary confinement for the woman. The reforms of 1920 and 1923 made provocation of abortion or contraceptional propaganda a "crime" (felony), later a "delit" (misdemeanor), called for trial before magistr ate instead of jury, but resulted in only about 200 convictions a year. The decree of 1939 extended the misdemeanor to women who aborted even if they were not pregnant, and provided for professional licenses such as that of surgeon or pharmacist to be suspended. The law of 1942 made abortion a social crime and increased the maximum penalty to capital punishment, which was exercised in 2 cases. About 4000 per year were convicted from 1942-1944. Now the law still applies to all who intend to abort, whether or not pregnant or successful, but punishemnt is limited to 1-5 years imprisonment, and 72,000 francs fine, or suspension of medical practice for 5 years. About 500 have been convicted per year. Since 1955 legal abortion has been available (to about 130 women over 4 years) if it is the only means to save the woman's life. Although pregnancy tests are controlled, the population desregards the law by resorting to clandestine abortion. The wealthy travel to Switzerland (where 68% of legal abortions are done on French women) or to England. Numbers are estimated by the French government at 250,000-300,000 per year, or 1 for every 2 live births, but by hospital statistics at 400,000-1,000,000 per year. The rest of the review covers abortion laws in Scandinavian, Central European, and individual US states as of 1969. PMID:12333138

    The article describes the isolation of a cowpox virus (CPXV) isolate originating from a horse. The skin of a foal, aborted in the third trimester, displayed numerous cutaneous papules. The histological examination showed A-type inclusion bodies within the lesion, typical for CPXV infections. This suspicion was confirmed by real-time PCR where various organs were analyzed. From skin samples, virus isolation was successfully performed. Afterwards, the whole genome of this new isolate "CPXV Amadeus" was sequenced by next-generation technology. Phylogenetic analysis clearly showed that "CPXV Amadeus" belongs to the "CPXV-like 1" clade. To our opinion, the study provides important additional information on rare accidental CPXV infections. From the natural hosts, the voles, species such as rats, cats, or different zoo animals are occasionally infected, but until now only two horse cases are described. In addition, there are new insights toward congenital CPXV infections. PMID:27159333

    In 1990 abortion literature was characterized by articles relating to 1) the safety of surgical abortion procedures, 2) advances in knowledge and experience with medical abortifacients such as mifepristone (RU 486), and 3) reviews of psychologic and ethical considerations. Although technical methods differ greatly between countries and continents, there is increasing similarity between termination protocols in the United States, the United Kingdom, and Europe. The advent of mifepristone will make this even more so. Surgically, although dilatation and evacuation procedures are far more common in the United States than in other countries, the literature reflects a fine-tuning of analysis and technique, with safety the major consideration. Knowledge about the effectiveness of mifepristone continues to grow, and the effective dose for early first-trimester termination appears established. There is increasing evidence that at least in the short term, the negative psychologic sequelae of abortion are infrequent and are inconsequential as a public health issue. PMID:1878507

    I refer for termination anyone who requests it for--pace Mr V Tunkel, (28 July, p 253)--the law is generally regarded as being one of "abortion on demand." I have some misgivings as I do not believe that women in early pregnancy are always in a fit state to make a considered decision, and they cannot in the nature of things be given time. I have, however, become increasingly worried about the morbidity arising from the procedure, and it is interesting that letters on the subject (25 August, pp 495 and 496) should be followed by one reporting rupture of the uterus during prostaglandin-induced abortion--yet another complication to add to those of cervical incompetence, pelvic sepsis, and permanent neurological damage. In so far as these tragedies usually follow late terminations Mr John Corrie's Bill is to be welcomed. A few further points. I am not so cynical as to think that every impregnation is the result of a thoughtless act of male lust. Unlike Professor Peter Huntingford (25 August, p 496), I listen to men as well as women, and many of them are deeply involved emotionally in the pregnancy they have helped to produce. Certainly I think a man should have the right to be consulted if his wife is to undergo a procedure that might damage her health. It is unfair contemptuously to dismiss as "whims" opinions that differ from ones own. These may result from genuine conscientious doubts or inability to cope from overwork and understaffing. Abortion is quite the most expensive form of contraception, and perhaps in these days of financial stringency this should be taken into account. "Bigotry" is defined in my dictionary as "blind zeal." This could be said of those who enthusiastically promote a course of action without regard to circumstances, safety, or cost. PMID:497770

    We conducted a survey of 358 young migrant women working in entertainment venues in China to explore the prevalence of and factors associated with two indicators of sexual and reproductive health: (i) multiple abortions and (ii) the dual risk of sexually transmitted infections (STI) and abortion history. One quarter (25.4%) of the women in this sample had multiple abortions during their lifetime and, of those with any abortion history, 18.3% had had an abortion outside of a regulated health clinic. One-third (33.0%) of the sample had had a STI during the past year, and approximately one-fourth (23.7%) of those women did not receive STI treatment in a public hospital. Approximately one-fourth (23.5%) of the sample reported both a history of abortion and an STI during the past year. Women with a history of multiple abortions had significantly lower income levels, were more likely to have sex with clients and with husbands, and tended more to use alcohol before sex. Women who experienced both abortion and STI risks were more likely to report having had unprotected sex, genitourinary tract infections symptoms, anxiety, illicit drug use, and suicidal ideation. Enhanced efforts are needed to improve reproductive and sexual health for female migrants in urban China, particularly those working in entertainment venues. PMID:25902189

    A pregnant 18-year-old Quarterhorse mare presented with fever, anorexia, tachycardia, tachypnea, and gastrointestinal hypermotility at day 68 of gestation. Potomac horse fever was diagnosed based on polymerase chain reaction (PCR) analysis of whole blood and a high antibody titer to Neorickettsia risticii. The mare made a rapid clinical recovery following antibiotic therapy, but aborted 98 days later. Necropsy on the aborted fetus revealed lymphohistiocytic colitis, lymphadenitis, myocarditis, and hepatitis. The placenta was grossly and histologically normal. Formalin-fixed lymph node, thymus, liver, and colon taken from the aborted fetus were positive by PCR for N. risticii DNA. Potomac horse fever is a common disease in horses that may result in delayed abortion. The microscopic lesions in the fetus are characteristic, and the diagnosis can be confirmed by PCR on formalin-fixed tissues. PMID:18987240

    Background: Mycoplasma infections are suggested as etiology of adverse pregnancy outcomes. Objective: The aim of this study was to evaluate the association of Mycoplasma hominis (M. hominis) infection and spontaneous abortion among pregnant women. Materials and Methods: In this case-control study that was conducted from August 2012 to January 2013, totally, 109 women were included with spontaneous abortion with gestational ages of 10-20 weeks (Cases), and 109 women with normal pregnancy with gestational ages between 20-37 weeks (Controls) in Sanandaj, Iran. Using specific primers and extracted DNA from endocervical swabs, a PCR test was conducted for detection of M. hominis infection in women. For comparison of qualitative and quantitative variables, independent Fisher tests were used and p<0.05 was considered significant. Results: The total frequency of M. hominis infection was 6 (2.75%) in women. The frequency of M. hominis infection was 2 (1.83%) in the case group (spontaneous abortion) and 4 (3.66%) in the control group, respectively. In both case and control groups, no association was seen between M.hominis infection and spontaneous abortion (OR=0. 49, CI 95%: 0.08-2.73, p=0. 683). Conclusion: M. hominis was positive in the genital tract of some pregnant women, but it was not associated with spontaneous abortion. However, to prevent adverse pregnancy outcomes in women, foetus and neonate, routine screening and treatment for the genital Mycoplasma is recommended. PMID:27294216

    OBJECTIVE: To determine the seroprevalence and correlates of HIV infection in a subpopulation of women of childbearing age in Montreal. DESIGN: Anonymous unlinked seroprevalence study. SETTING: Pregnancy termination unit in a teaching hospital in Montreal. PARTICIPANTS: Women presenting for abortion from July 1989 to June 1993 who resided in Quebec and were not known to have HIV infection; 12,017 (99.6%) of 12,068 eligible women were included in the study. INTERVENTION: HIV antibody testing of serum left over from samples obtained for routine Rh typing; the same algorithm as for serodiagnostic testing, namely enzyme immunoassay (EIA) followed by confirmatory testing of repeatedly EIA-reactive samples, was used. OUTCOME MEASURES: HIV serostatus by age, marital status, region of residence (metropolitan Montreal versus other), country of birth and number of living children. RESULTS: Most (84.7%) of the subjects resided in metropolitan Montreal. The median age was 27.0 (range 13 to 50) years. The serum samples of 22 women were confirmed to be HIV positive, for an overall seroprevalence rate of 1.8 per 1000 (95% confidence interval 1.1 to 2.8). The seroprevalence rate did not vary significantly by age, marital status, region of residence or study year. However, it was strongly correlated with country of birth: Canada 0.16, Haiti 23.5, HIV-endemic countries other than Haiti 5.3 and non-HIV-endemic countries other than Canada 0.0 per 1000. The seroprevalence rate among women born in Haiti was 147 times higher than that among women born in Canada (p < 0.0001). Of the women born in Haiti the rate was 3.0 times greater among those who immigrated to Canada in 1985 or later than among those who immigrated earlier (p = 0.047). CONCLUSIONS: The results of this study indicate that the HIV seroprevalence rate among women in Montreal is strongly associated with country of birth, women born in HIV-endemic countries, especially Haiti, having the highest rate.

    The history, circumstances, clinical signs, post mortem lesions, morbidity, mortality and laboratory findings are described in an abortion storm in sheep that occurred in Mpumalanga, South Africa, associated with infection with Arcobacter skirrowii. Altogether, about 200 Suffolk Down ewes lost 60 lambs in late pregnancy or at term. Although only three foetuses were submitted for investigation, two had signs consistent with a diagnosis of A. skirrowii infection and the organism was isolated from the placentas of both specimens. No abortions had occurred in previous years, or have subsequently. There were no animal introductions prior to the outbreak that could have indicated a source of infection. One stillborn lamb submitted subsequently had lesions consistent with dystocia, and the history and circumstantial evidence indicated that dystocia had been a factor in several more losses. No ewes or rams had shown signs of diarrhoea or other diseases associated with A. skirrowii infection. Twenty-two faecal, preputial and vaginal swab specimens taken from six rams and 13 ewes after the abortion event were all negative for A. skirrowii. This is the first report of abortions in sheep associated with A. skirrowiiin South Africa. Because the genus Arcobacter is similar to Campylobacter, it is possible that infection has gone unrecognised in the past. Veterinarians and laboratories should take note and include this genus in the list of potential abortifacient organisms. The possible role of Arcobacter species in other diseases like enteritis and mastitis, as well as the potential role as a zoonosis, must be borne in mind. PMID:27476399

    Neospora caninum is a major cause of abortion in cattle. However, it is not known why not all infected animals abort. In this study, Th1 (IFN-γ), Th2 (IL4) and T reg (IL-10) cytokine gene expression was examined by real time PCR using the TaqMan approach in all of these dams and their foetuses after experimental infection with the isolate Nc-Spain7 at 110 days of pregnancy and euthanasia 6 weeks after infection. In prior published work, foetal death was observed in three of six infected dams and transplacental infection in all the 6 infected foetuses. In the spleen of the dams, IL-4 expression was down-regulated in dams with aborted/non viable foetuses compared to both uninfected dams (controls, n=3) and infected dams with live fetuses at euthanasia. In the lymph nodes draining the placenta, up-regulated expression of IL-4 was observed in infected dams with live foetuses compared to control dams. In the placenta, infected dams with live foetuses had significantly up-regulated IFN-γ in both caruncle and cotyledon and up-regulated IL-10 in cotyledon compared to control dams. Infected live foetuses showed up-regulated expression of IFN-γ and IL-10 in foetal spleen, and showed downregulated expression of IL-4 in the thymus compared to control uninfected foetuses. Expression of any cytokine in the thymus was significantly lower compared to the levels observed in foetal spleen. The results indicate an up-regulated expression of Th1, Th2 and Treg in infected dams with live foetuses and in their foetuses. On the other hand, down-regulation of Th2 immune responses and Treg cytokines were observed in infected dams which had aborted or had non-viable foetuses at euthanasia, suggesting an immunological recovery of cytokine gene expression levels in dams a few weeks after an abortion occurred.

    Neospora caninum and Toxoplasma gondii are closely related cyst-forming apicomplexan parasites identified as important causes of reproductive failure in cattle and small ruminants, respectively. Protozoan abortion in small ruminants is traditionally associated with T. gondii, but the importance of N. caninum remains uncertain. The aim of this study was to investigate the presence of N. caninum and T. gondii infections in abortion cases in small ruminants submitted for diagnosis. For this purpose, 74 ovine and 26 caprine aborted foetuses were recovered from different areas in Spain. Foetal histopathology was used to detect the presence of protozoal-associated lesions in brain. The presence of N. caninum and T. gondii was confirmed by PCR. Protozoal infection was detected in 17 out of 100 (17%) foetuses examined by at least one of the diagnostic techniques used. Lesions suggestive of protozoal infection were observed in 10.8% (8/74) and 15.4% (4/26) of the ovine and caprine abortions respectively. N. caninum and T. gondii infection was detected by PCR in 6.8% (5/74) and 5.4% (4/74) of sheep foetuses, respectively, of which five showed protozoal-associated lesions. N. caninum DNA was detected in 11.5% (3/26) of goat foetuses, of which two showed protozoal-associated lesions, whereas T. gondii DNA was detected in one goat foetus with no lesions. The simultaneous presence of N. caninum and T. gondii DNA was detected in one sheep foetus with severe lesions. This study demonstrates that N. caninum plays a significant role in abortion in small ruminants in the studied population. In addition, our results highlight the importance of differentiating between protozoa whenever characteristic lesions are observed. PMID:22260901

    The anatomical progression of chlamydial infection was studied in different areas of the placenta, using a mouse model and two inoculation times: early pregnancy (day 7, group A) and midpregnancy (day 11, group B). The first population cells affected were decidual cells and neutrophils located just at the limits of the maternal and fetal placenta. The following invaded area was the layer of giant cells. Complete colonization of the maternal placenta occurred after day 15 of pregnancy independently of the inoculation time, the metrial gland being the last area to be invaded; numerous granulated metrial gland (GMG) cells were infected. Finally, chlamydial inclusions were observed in labyrinthine trophoblastic cells from day 18 of pregnancy onward. Since no fetal damage was observed, it seems that an indirect mechanism involving the lysis of GMG cells and neutrophil infiltration of the decidua and metrial gland may be the pathogenic mechanism that leads to abortion.

    ToRCH infections (toxoplasmosis, rubella, cytomegalovirus and Herpes simplex virus) have long been known to be associated with bad obstetric outcomes. However, little information is available about the impact of ToRCH co-infections on the outcome of pregnancy. Hence, we tested the IgG and IgM antibodies to Toxoplasma gondii, Rubella, Cytomegalovirus and Herpes Simplex Virus among 81 pregnant women with abortion (case group) and 98 pregnant women with normal delivery (control group). In the single-infection model, only CMV-IgM seropositivity was significantly increased in case than control group (25.9% in case and 12.2 % in control, OR = 2.5, P = 0.019). In the co-infection model, 14 patterns were recognized, but two patterns were significantly increased in the case than the control group. Co-infection of T. gondii IgG + CMV IgM was 9.1-fold increased in the case than the control group (8.6% in the case and 1% in control, OR = 9.1; P = 0.024). Also, co-infection of T. gondii IgG + HSV IgG + CMV IgM was 7.7-fold increased in case than the control group (7.4% in case and 1 % in control, OR = 7.7; P = 0.04). Although the OR of other co-infections was higher in the case than the control group, the difference was not statistically significant. These findings indicate that ToRCH co-infections are associated with increased risk of abortion than single infection. Hence, the rates of co-infections should be considered in prenatal screening of ToRCH infections. PMID:26499091

    Background The aim of this study was to apply the nested-PCR and bioassay methods in detection and genotyping of Toxoplasma gondii infection in provided sheep aborted fetus samples from Qazvin Province of Iran. Methods Eighteen sheep aborted fetal samples were studied by nested-PCR-RFLP, histopathological observation and microbiological assay. Bioassay in mice was carried out by inoculating the brain samples intraperitoneally. Results The results demonstrated the frequency of 66% infected sheep aborted fetal samples with T. gondii type one. Although we could not isolate any parasite from inoculated mice even after three passages, but it was confirmed histopathologically formation of cyst like bodies in prepared mice brain sections. Conclusion The results of the performed nested-PCR and formation of brain cyst in inoculated mice exhibited that T. gondii type one infection might be considered as one of the major causative agents for abortion in ewes.

    Candida species are opportunistic fungi associated with immunosuppression and are the most commonly isolated fungal pathogens from the human central nervous system. Invasive candidiasis is reported uncommonly in animals and there have only been two reports of candidal infection of the brain. This report presents a case of a cerebral candidal abscess in an aborted late-term calf co-infected with bovine viral diarrhoea virus. Candida etchellsii, a species not previously identified as pathogenic, was identified as the causative agent by polymerase chain reaction. PMID:26895887

    The aims of this study were to identify the occurrence of Toxoplasma gondii and Neospora caninum abortions in goats from Argentina by serological, macroscopical and microscopical examination and bioassay, and to characterize the obtained isolates by molecular techniques. For this purpose, 25 caprine fetal fluids, 18 caprine fetal brains and 10 caprine placentas from 8 dairy/meat goat farms from Argentina were analyzed. Gestational age of the aborted fetuses was determined in 18 cases. Protozoal infections were detected by at least one of the applied diagnostic techniques in 44% (11/25) of examined fetuses; specifically, 24% (6/25) were positive to T. gondii, 8% (2/25) were positive to N. caninum and 12% (3/25) were positive to both parasites. In this study IFAT titers were similarly distributed in younger and older fetuses. Macroscopical and microscopical examination of one placenta revealed chalky nodules in the fetal cotyledons and normal intercotyledonary areas, as well as necrosis and calcification of mesenchymal cells in villi. Tachyzoites were observed in peritoneal wash from 2 mice inoculated with brain and a pool of brain and placenta of two fetuses. Cell culture growth of tachyzoites was achieved from one inoculated mouse, and confirmed as T. gondii by PCR. The T. gondii isolate was identified as atypical or non-canonical by nested-PCR-RFLP. This is the first study that investigated the involvement of N. caninum and T. gondii in cases of goat abortion in Argentina. PMID:25128663

  7. Abortively Infected Astrocytes Appear To Represent the Main Source of Interferon Beta in the Virus-Infected Brain

    ABSTRACT Interferon beta (IFN-β) is a key component of cellular innate immunity in mammals, and it constitutes the first line of defense during viral infection. Studies with cultured cells previously showed that almost all nucleated cells are able to produce IFN-β to various extents, but information about the in vivo sources of IFN-β remains incomplete. By applying immunohistochemistry and employing conditional-reporter mice that express firefly luciferase under the control of the IFN-β promoter in either all or only distinct cell types, we found that astrocytes are the main producers of IFN-β after infection of the brain with diverse neurotropic viruses, including rabies virus, Theiler's murine encephalomyelitis virus, and vesicular stomatitis virus. Analysis of a panel of knockout mouse strains revealed that sensing of viral components via both RIG-I-like helicases and Toll-like receptors contributes to IFN induction in the infected brain. A genetic approach to permanently mark rabies virus-infected cells in the brain showed that a substantial number of astrocytes became labeled and, therefore, must have been infected by the virus at least transiently. Thus, our results strongly indicate that abortive viral infection of astrocytes can trigger pattern recognition receptor signaling events which result in secretion of IFN-β that confers antiviral protection. IMPORTANCE Previous work indicated that astrocytes are the main producers of IFN after viral infection of the central nervous system (CNS), but it remained unclear how astrocytes might sense those viruses which preferentially replicate in neurons. We have now shown that virus sensing by both RIG-I-like helicases and Toll-like receptors is involved. Our results further demonstrate that astrocytes get infected in a nonproductive manner under these conditions, indicating that abortive infection of astrocytes plays a previously unappreciated role in the innate antiviral defenses of the CNS.

    Herpes simplex virus (HSV) was studied in ejaculate of 36 men whose wives had the history of spontaneous abortions, or failure of artificial insemination (AI), or extracorporeal fertilization (ECF). The control group consisted of 222 patients examined prophylactically after urogenital inflammation or for primary infertility. HSV was detected with immunofluorescence (IF) reaction with monoclonal antibodies to HSV antigens, rapid culture method (RCM) and transmission electronic microscopy. HSV antigens were detected in fraction of mobile spermatozoa in 13 (65%) of 20 samples from patients of the study group. HSV detectability in the study group was significantly higher than in the controls (p = 0.003). Intragametic capsides of HSV were detected at ultrastructural investigation in 13 of 19 (68%) ejaculate samples from patients of the study group in whom IF and/ or RCM results were positive. The study of 6 ejaculate samples of this group in which HSV was not detected by IF or RCM and 24 control samples HSV capsides were not detected. The following conclusions can be made: mobile spermatozoa of normal morphology can be infected with HSV; as shown morphologically, samples of ejaculate from men whose wives had spontaneous abortions contained intragametic HSV capsides; intragametic HSV infection of spermatozoa had a negative effect on the course of pregnancy and/or embryon vitality.

    A positive score on a modified acid-fast (MAF)-stained smear test of fresh placenta was used to identify a group of bovine abortion submissions believed to be infected with Coxiella burnetii. Immunohistochemical (IHC) testing for Coxiella and Chlamydia antigens was performed on 14 MAF smear-positive cases as well as 29 MAF smear-negative cases received during the study period. Nine MAF smear-positive cases as well as 1 MAF smear-negative case were Coxiella-positive via the IHC test. No placentas were positive for Chlamydia antigen. Various histopathologic features were categorized for all placentas and the presence or absence of selected risk categories was also graded for each case. The results between Coxiella IHC-positive cases and Coxiella IHC-negative/MAF-negative cases were compared using Fisher's exact test (P value at 95% confidence). Significant associations were found between Coxiella IHC-positive cases and the presence of placental inflammation (P = 0.0027), placental necrosis (P = 0.012), fetal pneumonia (P = 0.0152), and the visibility of Coxiella-like organisms within trophoblasts on hematoxylin and eosin-stained sections (P < 0.0001). Histopathologic features of Coxiella IHC-positive placentas included infiltration of the chorionic stroma by mononuclear cells, necrosis of chorionic trophoblasts, and focal exudation of fibrin and neutrophils. The results indicate that MAF smears are a good screening tool for the presence of Coxiella in placentas from bovine abortion cases and that the detection of this pathogen in aborted placentas via traditional staining or IHC methods is usually associated with placentitis.

    Northern (RNA) blot analysis has been used to show that synthesis of early mRNA species is similar in monkey cells productively or abortively infected with human adenovirus. mRNA species from all five major early regions (1A, 1B, 2, 3, 4) are identical in size and comparable in abundance whether isolated from monkey cells infected with adenovirus type 2 or with the host range mutant Ad2hr400 or coinfected with adenovirus type 2 plus simian virus 40. The mRNA species isolated from monkey cells are identical in size to those isolated from human cells. Production of virus-associated RNA is also identical in productive and abortive infections of monkey cells. Synthesis of virus-associated RNA is, however, significantly greater in HeLa cells than in CV1 cells at late times after infection regardless of which virus is used in the infection.

    A study was undertaken to quantify the expression of prostaglandin (PG) receptors and find the effect of gestational age on expression of PG receptor genes in Chlamydia trachomatis-infected recurrent spontaneous aborters (RSA). Endometrial curettage tissue (ECT) was collected from 130 RSA (Group I) and 100 age-matched controls (Group II) at the Department of Obstetrics and Gynecology, Safdarjung Hospital, New Delhi (India). PCR was performed for diagnosis of C. trachomatis cryptic plasmid; mRNA expression of PG receptor genes was assessed by real-time PCR (q-PCR), while serum progesterone/estrogen levels were determined by respective commercial kits. Data were evaluated statistically. A total of 15.4 % RSA (GroupI) were diagnosed as C. trachomatis-positive (200 bp), whereas controls were uninfected. q-PCR showed significant upregulation (P<0.0001) of PGE2 (EP-1, EP-2, EP-3, EP-4), PGF2α (FP) and PGI2 (IP) receptors in Group I versus Group II. The expression of PG receptors increased significantly with advanced gestational age (P<0.002); however, only contractile receptors, EP-1, EP-3 and FP, were positively correlated with gestational age in Group-I. In infected RSA, mean serum progesterone level was significantly low (P<0.0001) while serum oestrogen was high (P<0.0001). Overall, the data suggest that increased expression of PG receptors, particularly contractile gene receptors (EP-1, EP-3, FP), with advanced gestational age and altered steroid levels could be a possible risk factor for abortion in Chlamydia-infected RSA.

  14. Activation of mRNA translation by phage protein and low temperature: the case of Lactococcus lactis abortive infection system AbiD1

    2009-01-01

    Background Abortive infection (Abi) mechanisms comprise numerous strategies developed by bacteria to avoid being killed by bacteriophage (phage). Escherichia coli Abis are considered as mediators of programmed cell death, which is induced by infecting phage. Abis were also proposed to be stress response elements, but no environmental activation signals have yet been identified. Abis are widespread in Lactococcus lactis, but regulation of their expression remains an open question. We previously showed that development of AbiD1 abortive infection against phage bIL66 depends on orf1, which is expressed in mid-infection. However, molecular basis for this activation remains unclear. Results In non-infected AbiD1+ cells, specific abiD1 mRNA is unstable and present in low amounts. It does not increase during abortive infection of sensitive phage. Protein synthesis directed by the abiD1 translation initiation region is also inefficient. The presence of the phage orf1 gene, but not its mutant AbiD1R allele, strongly increases abiD1 translation efficiency. Interestingly, cell growth at low temperature also activates translation of abiD1 mRNA and consequently the AbiD1 phenotype, and occurs independently of phage infection. There is no synergism between the two abiD1 inducers. Purified Orf1 protein binds mRNAs containing a secondary structure motif, identified within the translation initiation regions of abiD1, the mid-infection phage bIL66 M-operon, and the L. lactis osmC gene. Conclusion Expression of the abiD1 gene and consequently AbiD1 phenotype is specifically translationally activated by the phage Orf1 protein. The loss of ability to activate translation of abiD1 mRNA determines the molecular basis for phage resistance to AbiD1. We show for the first time that temperature downshift also activates abortive infection by activation of abiD1 mRNA translation. PMID:19173723

    A comparative study was conducted using data from naive bison (n = 45) and cattle (n = 46) from 8 and 6 studies, respectively, in which a standardized Brucella abortus strain 2308 experimental challenge was administered during midgestation. The incidence of abortion, fetal infection, uterine or mammary infection, or infection in maternal tissues after experimental challenge was greater (P < 0.05) in bison than in cattle. In animals that did abort, the time between experimental challenge and abortion was shorter (P < 0.05) for bison than for cattle. Brucella colonization of four target tissues and serologic responses on the standard tube agglutination test at the time of abortion did not differ (P > 0.05) between cattle and bison. The results of our study suggest that naive bison and cattle have similarities and differences after experimental exposure to a virulent B. abortus strain. Although our data suggest that bison may be more susceptible to infection with Brucella, some pathogenic characteristics of brucellosis were similar between bison and cattle. PMID:21976222

    In baby hamster kidney (BKH-21) cells abortively infected with adenovirus type 12, polysome-associated, virus-specific RNA could be detected starting 5 to 7 h after infection. The amount of this RNA reached a maximum between 10 to 12 h after infection and continued to be synthesized at a reduced level until late in infection (48 to 50 h.). In BHK-21 cells transformed by adenovirus type 12 (HB cells), 0.26% of the polysome-associated mRNA was virus specific. The size of the virus-specific mRNA isolated from polysomes of BHK-21 cells abortively infected with, or transformed by adenovirus type 12 was determined by electrophoresis in polyacrylamide gels in 98% formamide, i.e., under conditions which eliminated secondary structure or aggregation of RNA. In abortively infected hamster cells viral mRNA size classes of molecular weights 0.9 times 10-6 and 0.65 times 10-6 to 0.67 times 10-6 were predominant. A minor fraction of 1.5 times 10-6 daltons was consistently found and increased with time after infection. Late after infection (24 to 26 h), viral mRNA of 1.9 times 10-6 daltons was also observed. The size distribution of adenovirus type 12-specific mRNA from transformed hamster cells (HB line) was very similar to that in abortively infected cells, except that the relative amount of the viral mRNA fraction of 1.5 times 10-6 daltons was much higher. It is uncertain whether the viral mRNA of high-molecular-weight represents mixed transcripts derived from integrated viral genomes and adjacent host genes. PMID:1167602

    Introduction Plasmodium chabaudi AS-infection in pregnant A/J and C57BL/6J mice results in mid-gestational pregnancy loss. Although associated with increased systemic and placental pro-inflammatory responses and coagulopathy, the molecular mechanisms that underlie poor pregnancy outcomes in these mice are not yet fully understood. This study investigates the relationships between inflammation, apoptosis and malaria-induced pregnancy loss. Methods Infection with Plasmodium chabaudi AS in early murine pregnancy and term human placental tissues from an endemic setting were assessed by histology, immunohistochemistry, TUNEL staining, real-time PCR, flow cytometry, western blot, and ELISA. Results Quantitative PCR reveals accumulation of lymphocytes and monocytes and upregulation of chemokines that attract these cell types in malaria-exposed mid-gestational A/J conceptuses. Monocyte accumulation is confirmed by flow cytometry and placental immunohistochemistry. Concurrent with initiation of malaria-induced abortion, markers of apoptosis are evident in the junctional zone, but not the labyrinth, of A/J placentae. In contrast, mid-gestation conceptuses in infected C57BL/6J lack evidence for monocyte accumulation, exhibiting low or no in situ placental staining despite trophoblast immunoreactivity for the monokine, CCL2. Additionally, placental apoptosis is not consistently observed, and when evident, appears after malaria-induced abortion typically initiates. Similarly, trophoblast apoptosis in term human placental malaria is not observed. Of those studied, a sole common feature of malaria-induced abortion in A/J and C57BL/6J mice is elevation of plasma tumor necrosis factor. Discussion Consistent with our previous observations, tumor necrosis factor is likely to be a central driver of malaria-induced pregnancy loss in both strains, but likely operates through mechanisms distinct from placental apoptosis in C57BL/6J mice.

    Bovine neosporosis has emerged as a main cause of abortion in cattle worldwide. An important question to understand the disease is why not all infected cows abort. In the present review we summarize the knowledge on markers related to the diagnosis and more importantly to the risk of abortion in the infected cow. Markers considered herein include those based on specific antibodies, antibody titers and antibody subtypes, cellular immunological markers, hormones and other proteins related to gestation. The identification of parasite molecules that are specifically identified in the aborting cows might help to understand the mechanism of parasite-associated abortion and control the disease.

    The objective of the present study was to improve the detection of B. abortus by PCR in organs of aborted fetuses from infected cows, an important mechanism to find infected herds on the eradication phase of the program. So, different DNA extraction protocols were compared, focusing the PCR detection of B. abortus in clinical samples collected from aborted fetuses or calves born from cows challenged with the 2308 B. abortus strain. Therefore, two gold standard groups were built based on classical bacteriology, formed from: 32 lungs (17 positives), 26 spleens (11 positives), 23 livers (8 positives) and 22 bronchial lymph nodes (7 positives). All samples were submitted to three DNA extraction protocols, followed by the same amplification process with the primers B4 and B5. From the accumulated results for organ, the proportion of positives for the lungs was higher than the livers (p=0.04) or bronchial lymph nodes (p=0.004) and equal to the spleens (p=0.18). From the accumulated results for DNA extraction protocol, the proportion of positives for the Boom protocol was bigger than the PK (p< 0.0001) and GT (p=0.0004). There was no difference between the PK and GT protocols (p=0.5). Some positive samples from the classical bacteriology were negative to the PCR and vice-versa. Therefore, the best strategy for B. abortus detection in the organs of aborted fetuses or calves born from infected cows is the use, in parallel, of isolation by classical bacteriology and the PCR, with the DNA extraction performed by the Boom protocol.

    Toxoplasmosis caused by Toxoplasma gondii is one of the most prevalent parasitic diseases in human beings. Human toxoplasmosis can be associated with serious clinical manifestations, particularly in developing fetus. The aim of the current study was to identify the possible lineage type of Toxoplasma gondii, molecularly detected in placental samples of women whose pregnancies were spontaneously terminated in the first trimester. Preliminary detection of Toxoplasma genomic materials was done by a SYBR green qPCR technology. Subsequent identification of Toxoplasma strain was done for the positive samples using PCR-restriction fragment length polymorphism (RFLP) at the SAG2 loci of T. gondii using restriction enzymes HhaI and Sau3AI. Out of 72 tested samples, Toxoplasma B1 gene was detected in 9 cases. Toxoplasma genotypes I and II in addition to unknown type were identified in 4, 3 and 2 cases respectively, while type III was not detected in our samples, hence excluded as a leading cause of abortion in humans in our preliminary study. Nevertheless, it remains uncertain to what extent the genotype of the parasite directly contributes to the clinical severity of human toxoplasmosis. Certainly, advanced molecular techniques targeting different Toxoplasma strains are crucial for better understanding of human toxoplasmosis. For more elucidation, additional studies are recommended intended for genetic characterization of such serious parasitic infection using larger number of samples. PMID:27363040

    Neospora caninum and Toxoplasma gondii are related parasites. The former is a common cause of abortion in dairy cattle. The latter has not been conclusively demonstrated in bovine fetuses. During the course of attempts to isolate N. caninum from aborted fetuses, T. gondii was isolated from 2 aborted fetuses, 1 from Portugal and 1 from the United States. Both isolates were made by bioassay of fetal brains in mice. The fetus from Portugal was about 5 mo in gestational age, and the fetus from the United States was a full-term stillborn. PMID:12537120

    Embryo abortion is the main cause of failure in chrysanthemum cross breeding, and the genes and proteins associated with embryo abortion are poorly understood. Here, we applied RNA sequencing and isobaric tags for relative and absolute quantitation (iTRAQ) to analyse transcriptomic and proteomic profiles of normal and abortive embryos. More than 68,000 annotated unigenes and 700 proteins were obtained from normal and abortive embryos. Functional analysis showed that 140 differentially expressed genes (DEGs) and 41 differentially expressed proteins (DEPs) were involved in embryo abortion. Most DEGs and DEPs associated with cell death, protein degradation, reactive oxygen species scavenging, and stress-response transcriptional factors were significantly up-regulated in abortive embryos relative to normal embryos. In contrast, most genes and proteins related to cell division and expansion, the cytoskeleton, protein synthesis and energy metabolism were significantly down-regulated in abortive embryos. Furthermore, abortive embryos had the highest activity of three executioner caspase-like enzymes. These results indicate that embryo abortion may be related to programmed cell death and the senescence- or death-associated genes or proteins contribute to embryo abortion. This adds to our understanding of embryo abortion and will aid in the cross breeding of chrysanthemum and other crops in the future. PMID:25288482

This test demonstrated the ability to perform an emergency pad abort of a full-scale 4.8 m diameter, 8200 kg crew capsule. During development of the critical separation mechanisms for this flight test, various challenges were overcome related to environments definition, installation complications, separation joint retraction speed, thruster ordnance development issues, load path validation and significant design loads increases. The Launch Abort System retention and release (LAS R&R) mechanism consisted of 6 discrete structural connections between the LAS and the crew module (CM) simulator, each of which had a preloaded tension tie, Superbolt torque-nut and frangible nut. During the flight test, the frangible nuts were pyrotechnically split, permitting the CM to separate from the LAS. The LAS separation event was the driving case in the shock environment for many co-located hardware items. During development testing, it was necessary to measure the source shock during the separation event so the predicted shock environment could be validated and used for certification testing of multiple hardware items. The Lockheed Martin test team measured the source separation shock due to the LAS R&R function, which dramatically decreased the predicted environment by 90% at 100 Hz. During development testing a hydraulic tensioner was used to preload the joint; however, the joint relaxation with the tensioner proved unsatisfactory so the design was modified to include a Superbolt torque-nut. The observed preload creep during lab testing was 4% after 30 days, with 2.5% occurring in the first 24 hours. The conversion of strain energy (preload) to kinetic energy (retraction) was measured to be 50-75%. Design features and careful monitoring of multiple strain gauges on each tension tie allowed a pure tensile load

    CRISPRs offer adaptive immunity in prokaryotes by acquiring genomic fragments from infecting phage and subsequently exploiting them for phage restriction via an RNAi-like mechanism. Here, we develop and analyze a dynamical model of CRISPR-mediated prokaryote-phage coevolution that incorporates classical CRISPR kinetics along with the recently discovered infection-induced activation and autoimmunity side effects. Our analyses reveal two striking characteristics of the CRISPR defense strategy: that both restriction and abortive infections operate during coevolution with phages, driving phages to much lower densities than possible with restriction alone, and that CRISPR maintenance is determined by a key dimensionless combination of parameters, which upper bounds the activation level of CRISPRs in uninfected populations. We contrast these qualitative observations with experimental data on CRISPR kinetics, which offer insight into the spacer deletion mechanism and the observed low CRISPR prevalence in clinical isolates. More generally, we exploit numerical simulations to delineate four regimes of CRISPR dynamics in terms of its host, kinetic, and regulatory parameters. PMID:26544847

    Based on the current literature, we aimed to provide an overview on Human Papillomavirus prevalence in normal pregnancies and pregnancies with adverse outcome. We conducted a systematic literature search in PubMed and Embase. Data extracted from the articles and used for analysis included HPV prevalence, pregnancy outcome, geographical location, investigated tissue types, and HPV detection methods. The overall HPV prevalence in normal full-term pregnancies was found to be 17.5% (95% CI; 17.3–17.7) for cervix, 8.3% (95% CI; 7.6–9.1) for placental tissue, 5.7% (95% CI; 5.1–6.3) for amniotic fluid, and 10.9% (95% CI; 10.1–11.7) for umbilical cord blood. Summary estimates for HPV prevalence of spontaneous abortions and spontaneous preterm deliveries, in cervix (spontaneous abortions: 24.5%, and preterm deliveries: 47%, resp.) and placenta (spontaneous abortions: 24.9%, and preterm deliveries: 50%, resp.), were identified to be higher compared to normal full-term pregnancies (P < 0.05 and P < 0.0001). Great variation in HPV prevalence was observed between study populations of different geographical locations. This review demonstrates an association between spontaneous abortion, spontaneous preterm delivery, and the presence of HPV in both the cervix and the placenta. However, a reliable conclusion is difficult to draw due to the limited number of studies conducted on material from pregnancies with adverse outcome and the risk of residual confounding.

    An eight-year-old thoroughbred mare with no previous history of illness aborted a fetus at 196 days of gestation, and its internal tissues were examined immunohistologically and bacteriologically. The placenta was not examined, but specimens of the intrauterine fluids and the dam's faeces were collected four days after the abortion and examined bacteriologically. No significant histological lesions were found in the fetus but the amnion and the umbilical cord were oedematous and had petechial haemorrhages. Rhodococcus equi was isolated in pure culture from the lung, heart and stomach contents of the fetus and from an intrauterine specimen and faeces of the dam. The anti-R equi antibody titre of the mare was high after the abortion. The diagnosis was confirmed in the lung of the fetus by immunohistochemical staining with R equi-specific antibodies. Isolates from the fetus and mare were identified as avirulent R equi by pcr and the mouse pathogenicity test. The avirulent isolates were characterised by pulsed-field gel electrophoresis, which yielded only one VspI profile in all the isolates from the fetus and its dam. PMID:17827474

    Discussions with several groups of low-income, middle-aged women in various countries of Latin America showed that most disapproved of abortion. In the course of group discussions about the motives of women who seek abortions and the psychological and sanitary conditions under which abortion occurs, however, their disapproval became less categorical. They began to accept the need to decriminalize abortion in order to protect women. The majority, strongly influenced by the Catholic Church, believed that human life begins at conception. Others disapproved of abortion because they feared it would be used as a birth control method and would encourage promiscuity. Most disapproved of abortion for single women attempting to escape family or social censure of unmarried motherhood. Fear of health effects or death from abortion and fear of divine punishment were also mentioned. Recognition of the anguish and pain suffered by women deciding to seek abortion and the difficulty of providing for the material and other needs of many children were factors that led to reconsideration of the wholesale condemnation of abortion. The women realized that such condemnations never take the woman's circumstances into account. Some of the women felt that aborting an unwanted pregnancy would be preferable to abandoning or neglecting an unwanted child. Many of the women came to feel that abortion should be legalized at least under some circumstances. PMID:12348503

    Ending the silent pandemic of unsafe abortion is an urgent public-health and human-rights imperative. As with other more visible global-health issues, this scourge threatens women throughout the developing world. Every year, about 19-20 million abortions are done by individuals without the requisite skills, or in environments below minimum medical standards, or both. Nearly all unsafe abortions (97%) are in developing countries. An estimated 68 000 women die as a result, and millions more have complications, many permanent. Important causes of death include haemorrhage, infection, and poisoning. Legalisation of abortion on request is a necessary but insufficient step toward improving women's health; in some countries, such as India, where abortion has been legal for decades, access to competent care remains restricted because of other barriers. Access to safe abortion improves women's health, and vice versa, as documented in Romania during the regime of President Nicolae Ceausescu. The availability of modern contraception can reduce but never eliminate the need for abortion. Direct costs of treating abortion complications burden impoverished health care systems, and indirect costs also drain struggling economies. The development of manual vacuum aspiration to empty the uterus, and the use of misoprostol, an oxytocic agent, have improved the care of women. Access to safe, legal abortion is a fundamental right of women, irrespective of where they live. The underlying causes of morbidity and mortality from unsafe abortion today are not blood loss and infection but, rather, apathy and disdain toward women. PMID:17126724

    We report the development of a real-time PCR assay for the quantitative detection of Neospora caninum in infected host tissues. The assay uses the double-stranded DNA-binding dye SYBR Green I to continuously monitor product formation. Oligonucleotide primers were designed to amplify a 76-bp DNA fragment corresponding to the Nc5 sequence of N. caninum. A similar method was developed to quantify the 28S rRNA host gene in order to compare the parasite load of different samples and to correct for the presence of potential PCR-inhibiting compounds in the DNA samples. A linear quantitative detection range of 6 logs with a calculated detection limit of 10(-1) tachyzoite per assay was observed with excellent linearity (R(2) = 0.998). Assay specificity was confirmed by using DNA from the closely related parasite Toxoplasma gondii. The applicability of the technique was successfully tested in a variety of host brain tissues: (i) aborted bovine fetuses classified into negative or positive Neospora-infected animals according to the observation of compatible lesions by histopathological study and (ii) experimentally infected BALB/c mice, divided into three groups, inoculated animals with or without compatible lesions and negative controls. All samples were also tested by ITS1 Neospora nested PCR and a high degree of agreement was shown between both PCR techniques (kappa = 0.86). This technique represents a useful quantitative diagnostic tool to be used in the study of the pathogenicity, immunoprophylaxis, and treatment of Neospora infection. PMID:11923330

    I recently watched a fascinating documentary about the crusade of Dr Bertram Wainer in the 1960s to bring the practice of illegal abortion in Victoria to an end. It documented the profound horror of the backyard abortion that so often ended in infection, sterility or death, and served as a potent reminder of a practice to which we must never return. Of course that cant happen again, abortion is legal now, isnt it? In Victoria in 1969 a Supreme Court judge ruled that an abortion is not unlawful if a doctor believed that: the abortion is necessary to preserve the woman from serious danger to her life or physical or mental health (Menhennit ruling). In Australia today however, abortion law remains conditional, unclear and inconsistent and, except in the ACT, is still part of criminal statutes. PMID:16969440

    Using three different polyomavirus hr-t mutants and two polyomavirus mlT mutants, the authors studied induction of S-phase by mutants and wild-type virus in quiescent mouse kidney cells, mouse 3T6 cells, and FR 3T3 cells. At different times after infection, they measured the proportion of T-antigen-positive cells, the incorporation of (/sup 3/H)thymidine, the proportion of DNA-synthesizing cells, and the increase in total DNA, RNA, and protein content of the cultures. In permissive mouse cells, they also determined the amount of viral DNA and the proportion of viral capsid-producing cells. In polyomavirus hr-t mutant-infected cultures, the onset of host DNA replication was delayed by several hours, and a smaller proportion of T-antigen-positive cells entered S-phase than in wild-type-infected cultures. Of the two polyomavirus mlT mutants studied, dl-23 behaved similarly to wild-type virus in many, but not all, parameters tested. The poorly replicating but well-transforming mutant dl-8 was able to induce S-phase, and (in permissive cells) progeny virus production, in only about one-third of the T-antigen-positive cells. From the experiments, the authors concluded that mutations affecting small and middle T-antigen cause a reduction in the proportion of cells responding to virus infection and a prolongation of the early phase, i.e., the period before cells center S-phase. In hr-t mutant-infected mouse 3T6 cells, production of viral DNA was <10% of that in wild-type-infected cultures; low hr-t progeny production in 3T6 cells was therefore largely due to poor viral DNA replication.

    About 150 human rhinovirus serotypes are responsible for more than 50 % of recurrent upper respiratory infections. Despite having similar 3D structures, some bind members of the low-density lipoprotein receptor family, some ICAM-1, and some use CDHR3 for host cell infection. This is also reflected in the pathways exploited for cellular entry. We found that even rhinovirus serotypes binding the same receptor can travel along different endocytic pathways and release their RNA genome into the cytosol at different locations. How this may account for distinct immune responses elicited by various rhinoviruses and the observed symptoms of the common cold is briefly discussed. PMID:27251607

    L-Methionine decarboxylase from Dryopteris filix-mas catalyzes the decarboxylation of L-methionine and a range of straight- and branched-chain L-amino acids to give the corresponding amine products. The deuterium solvent isotope effects for the decarboxylation of (2S)-methionine are {sup D}(V/K) = 6.5 and {sup D}V = 2.3, for (2S)-valine are {sup D}(V/K) = 1.9 and {sup D}V = 2.6, and for (2S)-lecuine are {sup D}(V/K) = 2.5 and {sup D}V = 1.0 at pL 5.5. At pL 6.0 and above, where the value of k{sub cat} for all of the substrates is low, the solvent isotope effects on V{sub max} for methionine are 1.1-1.2 whereas the effects on V/K remain unchanged, indicating that the solvent-sensitive transition state occurs before the first irreversible step, carbon dioxide desorption. At very high concentration, the product amine can promote transamination of the coenzyme. However, the reaction occurs infrequently and does not influence the partitioning between decarboxylation and substrate-mediated abortive transamination under steady-state turnover conditions. The partition ratio, normal catalytic versus abortive events, can be determined from the amount of substrate consumed by a known amount of enzyme at infinite time, and the rate of inactivation can be determined by measuring the decrease in enzyme activity with respect to time. Experiments conducted in deuterium oxide allowed the solvent isotope effects for the partition ratio and the abortive reaction to be determined. {sup 1}H NMR spectroscopic analysis of 3-(methylthio)-1-aminopropane isolated from incubations conducted in 50 molar % deuterium oxide at pL 4.8 and at pL 6.5 indicated that the proton donor was monoprotic and, therefore, is probably the imidazolium side chain of a histidine residue.

    This discussion focuses on the presently available technology of abortion induction techniques, which, though recent scientific interest has been in abortifacient agents, still primarily consists of some variation on the ancient technique of forcible cervical dilatation and pregnancy extraction in the first trimester. With the advent of legal abortions in the United States, technology and expertise that will lower the already low rate of abortion-associated complications are of paramount importance. That abortion may be preferable to contraception as a fertility control measure is argued from the following 3 drawbacks of present means of contraception: 1) they are preventitive and must be used in advance of need; 2) they fail more frequently than is usually thought (e.g., 4% for birth control pills, 5% for IUDs, and from 17-21% for more conventional methods); and 3) they are associated, though rarely, with potentially fatal side effects such as heart attack, stroke, or infection (some also raise the incidence of pathological pregnancies). The article devotes itself to an overview of complications of induced abortions (the mortality for legal abortions is 1/100,000 vs. maternal mortality of 10/100,000 in the United States), and to discussions of appropriate evacuation procedures per gestational age. Instruments and techniques for menstrual regulation (uterine aspiration during first trimester), are discussed. Procedures and instrumentation required for standard vacuum aspiration are covered. Use of analgesics and anesthetics during abortion procedures comprises one topic, with especial focus on the use of curettage for midtrimester terminations. Midtrimester terminations by amnioinfusions of abortifacients (saline, urea, and prostaglandins, e.g.) are analyzed. And, in addition to discussing sequelae for each particular abortion type, a section is devoted to the sequelae of induced abortion for subsequent pregnancy.

    Abortion or neonatal disease may follow infection with several alpha, beta and gamma-herpesviruses. The alpha-herpesvirus, equid herpesvirus-1 (EHV-1), causes single or epizootic abortions or neonatal deaths in equids, and the closely related virus EHV-4 causes sporadic equine abortions. In cattle, the alpha-herpesviruses, bovine herpesvirus-1 (infectious bovine rhinotracheitis virus) and bovine herpesvirus-5 (bovine encephalitis virus), and a gamma-herpesvirus, bovine herpesvirus-4, have all been implicated as causes of abortion. In pigs, suid herpesvirus-1 (SHV-1: pseudorabies virus), an alpha-herpesvirus, and SHV-2 (porcine cytomegalovirus), a beta-herpesvirus, each cause abortion or neonatal piglet losses. Caprine herpesvirus-1, canine herpesvirus and feline herpesvirus-1, all alpha-herpesviruses, cause abortions or neonatal deaths in goats, dogs and cats, respectively. This review discusses the pathogenesis, pathology and laboratory diagnosis of these herpesviral abortions and neonatal diseases, with an emphasis on experimental studies of each disease. Alternative reviews covering other aspects of each infection, such as the genetic and antigenic structure of the viruses, host immune responses and approaches to vaccination and disease control are indicated at appropriate points in the text.

Degradation of deoxyribonucleic acid and alteration of nucleic acid metabolism in suspension cultures of L-M cells infected with equine abortion virus. J. Bacteriol. 86:138–146. 1963.—Metabolic alterations in log-phase suspension cultures infected with equine abortion virus (EAV) were determined in L-M cells simultaneously labeled or prelabeled with H3- or C14-thymidine. Although infection produced an early stimulation of the uptake of labeled thymidine (TdR) into the acid-soluble fraction of concurrently labeled cells, incorporation of the isotope into deoxyribonucleic acid (DNA) was progressively inhibited. The specific activity of infected-cell DNA was 48% of the control at 24 hr. The rate of incorporation of isotope from 12 to 24 hr was 43 and 13 counts per min per μg of DNA per hr for control and infected cultures, respectively. Owing to degradation of DNA, synthesis could not be accurately determined with the concurrently labeled cells. On the other hand, with prelabeled cells, quantitative isotopic methods could be used to determine the amount of DNA synthesized by measuring dilution of specific activity, even though infection triggered degradation of DNA into acid-soluble components. With this method, the DNA synthesized in infected cultures for 24 hr was approximately five times greater than the slight net increase determined by the diphenylamine reaction. The specific activity of infected-cell DNA decreased and then remained fixed after 24 hr, with 53% of the radioactivity appearing in the medium by 48 hr. No radioactive CO2 was detected as a consequence of DNA degradation. Infected cells lost ribonucleic acid (RNA) as well as DNA; RNA and DNA were reduced by 64 and 50%, respectively, at 48 hr. The degradation of DNA was effectively inhibited by chelating agents in situ and is thought to be due to a deoxyribonuclease. Preliminary experiments with

    This study examines the prevalence, reasons, and predictors of unwanted pregnancies and induced abortions among ever married HIV-infected women attending a care facility in Maharashtra, Western India, and discusses its programmatic and policy implications. Retrospectively collected data of pregnancies conceived after the diagnosis of HIV were analyzed using descriptive and logistic regression techniques. Among the 622 women interviewed, 113 women had 158 pregnancies with known outcomes after HIV diagnosis. Among these pregnancies, 80 (51%) were unwanted and 79 (50%) were voluntarily terminated. Fear of transmitting HIV to the child was a frequently mentioned reason for an unwanted pregnancy (71.8%) and induced abortion (59.5%). Women from urban areas [OR 2.43 (95% CI 1.23-4.79)] and with two or more live births before HIV diagnosis [OR 3.33 (95% CI 1.36-8.20)] were significantly more likely to report an unwanted pregnancy. Women with two or more live births before HIV diagnosis [OR 3.16 (95% CI 1.20-8.35)], who did not know that HIV transmission to the baby can be prevented [OR 3.29 (95% CI 1.48-7.34)] and with an unwanted pregnancy [OR 4.82 (95% CI 2.33-10.00)], were significantly more likely to terminate the pregnancy. Despite increased coverage of antiretroviral treatment, effective provision of reproductive healthcare services to HIV-infected women remains challenging. A high prevalence of unwanted pregnancies and induced abortions and a low level of knowledge about prevention of mother to child transmission (PMTCT) underscore the need for preconception counseling and provision of comprehensive family planning services to HIV-infected women. Enrolling all HIV-infected pregnant women, irrespective of their decision to continue with their pregnancy, in the PMTCT program and discussing with HIV-infected women and their partners at HIV diagnosis a full array of contraceptive methods and not just consistent use of condoms might be helpful in reducing unwanted

    Cervical cancer is the fourth most common cancer in women and is almost exclusively caused by human papillomavirus (HPV) infection. HPV is also frequently associated with other cancers arising from mucosal epithelium, including anal and oropharyngeal cancers, which are becoming more common in both men and women. Viral persistence and progression through precancerous lesion stages are prerequisites for HPV-associated cancer and reflect the inability of cell-mediated immune mechanisms to clear infections and eliminate abnormal cells in some individuals. Cell-mediated immune responses are initiated by innate pathogen sensing and subsequent secretion of soluble immune mediators and amplified by the recruitment and activation of effector T lymphocytes. This review discusses early defensive mechanisms of innate responders to natural HPV infection, their influence on response polarization, and the underappreciated role of keratinocytes in this process.

    Toxoplasma gondii and Sarcocystis neurona are protozoan parasites with terrestrial definitive hosts, and both pathogens can cause fatal disease in a wide range of marine animals. Close monitoring of threatened southern sea otters (Enhydra lutris nereis) in California allowed for the diagnosis of dual transplacental transmission of T. gondii and S. neurona in a wild female otter that was chronically infected with both parasites. Congenital infection resulted in late-term abortion due to disseminated toxoplasmosis. Toxoplasma gondii and S. neurona DNA was amplified from placental tissue culture, as well as from fetal lung tissue. Molecular characterization of T. gondii revealed a Type X genotype in isolates derived from placenta and fetal brain, as well as in all tested fetal organs (brain, lung, spleen, liver and thymus). This report provides the first evidence for transplacental transmission of T. gondii in a chronically infected wild sea otter, and the first molecular and immunohistochemical confirmation of concurrent transplacental transmission of T. gondii and S. neurona in any species. Repeated fetal and/or neonatal losses in the sea otter dam also suggested that T. gondii has the potential to reduce fecundity in chronically infected marine mammals through parasite recrudescence and repeated fetal infection.

    Important insights have recently been gained in our understanding of how host immune responses mediate resistance to parasitic helminths and control associated pathological responses. Although similar cells and cytokines are evoked in response to infection by helminths as diverse as nematodes and schistosomes, the components of the response that mediate protection are dependent on the particular parasite. In this Review, we examine recent findings regarding the mechanisms of protection in helminth infections that have been elucidated in murine models and discuss the implications of these findings in terms of future therapies.

    Determination of fetal serum amyloid A (SAA) concentrations in aborted fetuses can provide valuable information regarding the infectious and/or inflammatory process of abortion in horses. To investigate the relationship between fetal SAA levels and the infectious/inflammatory disease process in feto-placental tissues, a SAA ELISA was used to test heart serum samples of 89 equine fetuses that were necropsied and diagnosed in the following groups: a multiorgan disease process diagnosed with an identified microorganism (14 cases, group 1); only placentitis diagnosed with an identified microorganism (nine cases, group 2); only placentitis diagnosed with no microorganism identified (six cases, group 3); and no infectious or inflammatory disease process diagnosed (60 cases, group 4). Serum amyloid A concentrations in equine fetuses were elevated from 10.5 to ≥40 mg/L in 10 of 14 cases in group 1; and from less than 2.5 mg/L to greater than 40 mg/L in seven of nine cases in group 2. In group 3, SAA concentrations were found to be less than 2.5 mg/L in five of six cases. In group 4, SAA concentrations were less than 2.5 mg/L in 55 cases, whereas in five cases SAA concentrations were elevated. Statistical significant differences were found between the concentrations of SAA in fetal horse blood and the presence of infectious and/or inflammatory disease process in the feto-placental tissues when a causative microorganism was identified. These results suggest that testing SAA concentrations in fetal heart blood may aid in further understanding the causes of abortions in horses. PMID:27125694

    Roughly 20% of all clinical pregnancies evolve into "spontaneous abortions". The causes of spontaneous abortion have been determined in under 60% of the total and comprise genetic, infectious, hormonal and immunological factors. In some cases the immune tolerance mechanism may be impaired and the foetus immunologically rejected (IMA, immunologically mediated abortion). The immunological mechanism implicated depends on the time in which pregnancy loss takes place. During preimplantation and up to the end of implantation (13th day) the cell-mediated immune mechanism (potential alloimmune etiologies) is responsible for early abortion. This mechanism involves immunocompetent decidual cells (eGL, endometrial granulated lymphocytes) already present during pre-decidualization (late luteal phase) and their production of soluble factors or cytokines. Once the implantation process is over, after blastocyst penetration of the stroma and the decidual reaction of uterine tissue, IMA could be caused by cell-mediated and humoral mechanism (anti-paternal cytotoxic antibodies or autoantibody etiology), by the production of paternal anti major histocompatibility complex antibodies, or even by an autoimmune disorder leading to the production of autoantibodies (antiphospholipid antibodies, antinuclear antibodies or polyclonal B cell activation). The diagnostic work-up adopted to select IMA patients is crucial and includes primary (karyotype of both partners, toxo-test, hysterosalpingography, endometrial biopsy, thyroid function tests, serum hprolactin, luteal phase dating) and secondary (full hemochromocytometric test, search for LE cells, lupus anticoagulant, anticardiolipin, antinuclear antibodies, Rheumatoid factor, blood complement VDRL) investigations. Therapeutical approaches vary. If autoimmune disorders are demonstrated therapies with different combinations of corticosteroids, aspirin and heparin or intravenous immunoglobulin are administered. Otherwise, therapy with paternal

    Aerosol exposure of eight pregnant sows to cell-culture- propagated Lelystad virus resulted in clinical signs characteristic of so-called mystery swine disease. After an incubation of 4-7 days, all sows were inappetant and listless for 6-9 days. Two sows developed a transient red-blue discolouration of the ears ('abortus blauw' or blue ear disease) accompanied by abdominal respiration, and two had a fever for one day only. One sow aborted at 109 days of gestation. The other seven sows, farrowing between 113 and 117 days of gestation, gave birth to numerous mummified, dead, and weak piglets. Of these seven, the mean number of piglets born dead to each sow was 4.6 and the mean number born alive was 7.7; 3.1 piglets per sow (40%) died within the first week. Lelystad virus was isolated from 31 piglets, which were born dead or died shortly after birth. Antibody was detected in precolostral blood samples or ascitic fluids of 23 piglets, a finding which demonstrated transplacental passage of the virus in six out of eight litters. We conclude that Lelystad virus is the causal agent of mystery swine disease. Since its aetiology is no longer a mystery, we propose the more appropriate name 'porcine epidemic abortion and respiratory syndrome (PEARS)'. PMID:1949539

    Snakehead fish vesiculovirus (SHVV) is a negative strand RNA virus which can cause great economic losses in fish culture. To facilitate the study of SHVV-host interactions, the susceptibility of zebrafish embryonic fibroblast cell line (ZF4) to the SHVV was investigated in this report. The results showed that high amount of viral mRNAs and cRNAs were detected at the 3 h post-infection. However, the expressions of the viral mRNAs and cRNA were decreased dramatically after 6 h post-infection. In addition, the expressions of interferon (IFN) and interferon-induced GTP-binding protein Mx were all up regulated significantly at the late stage of the infection. Meanwhile, the expressions of Retinoic acid-inducible gene I (RIG-I) and Melanoma differentiation-associated gene 5 (MDA5) were also all up-regulated significantly during the infection. Two isoforms of DrLGP2 from zebrafish were also cloned and analyzed. Interestingly, the expression of DrLGP2a but not DrLGP2b was significantly up-regulated at both mRNA and protein levels, indicating that the two DrLGP2 isoforms might play different roles during the SHVV infection. Transfection experiment showed that viral replicative intermediates were required for the activation of IFN-α expression. Taken together, the abortive infection of SHVV in ZF4 cells was associated with the activation of RLRs pathway, which was activated by viral replicative intermediates. PMID:25794284

    Selected brains and fetal viscera from 190 aborted or stillborn bovine fetuses submitted to Veterinary Investigation Centres in England and Wales between August 1992 and January 1993 were examined histologically. Non-suppurative inflammation of the brain and/or myocardium and placental cotyledons was identified by light microscopy in 20 (10.5 per cent). An immunocytochemical examination of fixed tissue sections using antisera against Neospora caninum, Toxoplasma gondii and Sarcocystis species revealed positive immunolabelling for N caninum in the brains of eight (4.2 per cent), but no labelling with anti-T gondii or anti-Sarcocystis species antisera was evident. These results suggest that N caninum may be an important cause of reproductive failure in cattle in England and Wales. PMID:7571263

    Related to its potential vulnerability the respiratory tract has a very complex and effective defence apparatus. The interaction between these defence mechanisms and certain characteristics of aetiological agents results in a pattern in which initial infections by these agents tend to occur at specific sites in the tract. Infections in which the primary portal of entry is in the upper respiratory tract include Bordetella bronchiseptica and Haemophilus spp in pigs; Pasteurella spp in cattle, sheep, pigs; Mycoplasma spp in cattle, sheep, pigs and poultry; equine herpesvirus 1 in horses; infectious bovine rhinotracheitis in cattle; parainfluenza 3 in cattle and sheep; infectious laryngo-tracheitis and infectious bronchitis in poultry; feline viral rhinotracheitis and calicivirus in cats; Aujeszky's disease virus and swine influenza in pigs; and equine influenza in horses. Infections in which the primary portal of entry is in the lower respiratory tract include Aspergillus fumigatus in poultry and mammals, respiratory syncytial virus in cattle, distemper virus in dogs and adenovirus in cattle and dogs. A fuller understanding of the interactions between an agent and the host at the point of entry would make it much easier to develop effective vaccines and therapeutic agents. PMID:16030806

    Diarrheagenic Escherichia coli organisms are major causes of morbidity and mortality worldwide. Although most strains of E. coli are harmless commensals, a few types have emerged that are capable of disrupting the normal physiology of the human gut, producing illness ranging from watery diarrhea to fatal hemorrhagic colitis. Diarrheagenic E. coli cause infection by a variety of complex mechanisms, some of which are incompletely understood. These include adherence, elaboration of toxigenic mediators, invasion of the intestinal mucosa, and transportation of bacterial proteins into the host cells. Specific components of the host-microbial interaction that cause damage have been identified, increasing our understanding of the mechanisms of diarrhea. This article reviews some of the recent findings about the pathogenesis and infectious processes involved in three emerging pathotypes of this fascinating gram-negative bacterium. PMID:11927041

    Specific guidance functions and trajectory design of return to launch site (RTLS) and transoceanic abort landing (TAL) intact abort profiles, as well as the increasing emphasis on contingency aborts, are presented. Various systems failures including Space Shuttle main engine failures and detailed technical analyses, including the design of powered flight abort trajectories, are considered. The most critical of flight abort situations is the RTLS, while TAL is the preferred abort when uphill capability is no longer available. It is concluded that one principle must remain to ensure continuing success of Space Shuttle flights: namely that intact and contingency aborts necessitate development to ensure safe return of the vehicle, payload, and crew whenever possible.

    Abortion is an important means of family planning, especially when contraception is unavailable or when it fails. Morbidity associated with legal abortion is low, though illegal abortion is a common cause of maternal mortality. The Union of Soviet Socialist Republic, Hungary, Yugoslavia, Czechoslovakia, Romania, Poland, and the German Demogratic Republic all have laws legalizing abortion. Legalized abortion is the surest method of population control and should be promoted if the moral and religious objections can be overcome. PMID:12255647

    1988-01-01

    During the period between 1977 and the first quarter of 1988, 35 countries liberalized their abortion laws and four countries limited grounds for the procedure. Most legislation has extended abortion eligibility through traditional indications such as danger to maternal health or fetal handicap, but a number of other indications have been created such as adolescence, advanced maternal age, family circumstances, and AIDS or HIV infection. A number of countries have redesigned their abortion laws as part of a comprehensive package to facilitate access to and delivery of contraception, voluntary sterilization, and abortion services. Abortion litigation has increased and stimulated the liberalization of abortion provisions and the support of women's autonomous choice within the law. In Canada, the entire criminal prohibition of abortion was held unconstitutional for violating women's integrity and security. In contrast, Latin American and other constitutional developments may limit legal abortion to instances of danger to women's lives. PMID:3048126

    Analysis of abortion in Mexico from a juridical perspective requires recognition that Mexico as a national community participates in a double system of values. Politically it is defined as a liberal, democratic, and secular state, but culturally the Judeo-Christian ideology is dominant in all social strata. This duality complicates all juridical-penal decisions regarding abortion. Public opinion on abortion is influenced on the 1 hand by extremely conservative groups who condemn abortion as homicide, and on the other hand by groups who demand legislative reform in congruence with characteristics that define the state: an attitude of tolerance toward the different ideological-moral positions that coexist in the country. The discussion concerns the rights of women to voluntary maternity, protection of health, and to making their own decisions regarding their bodies vs. the rights of the fetus to life. The type of analysis is not objective, and conclusions depend on the ideology of the analyst. Other elements must be examined for an objective consideration of the social problem of abortion. For example, aspects related to maternal morbidity and mortality and the demographic, economic, and physical and mental health of the population would all seem to support the democratic juridical doctrine that sees the clandestine nature of abortion as the principal problem. It is also observed that the illegality of abortion does not guarantee its elimination. Desperate women will seek abortion under any circumstances. The illegality of abortion also impedes health and educational policies that would lower abortion mortality. There are various problems from a strictly juridical perspective. A correct definition of the term abortion is needed that would coincide with the medical definition. The discussion must be clearly centered on the protected juridical right and the definition of reproductive and health rights and rights to their own bodies of women. The experiences of other

    We use unique data on abortions performed in New York State from 1971–1975 to demonstrate that women travelled hundreds of miles for a legal abortion before Roe. A100- mile increase in distance for women who live approximately 183 miles from New York was associated with a decline in abortion rates of 12.2 percent whereas the same change for women who lived 830 miles from New York lowered abortion rates by 3.3 percent. The abortion rates of nonwhites were more sensitive to distance than those of whites. We found a positive and robust association between distance to the nearest abortion provider and teen birth rates but less consistent estimates for other ages. Our results suggest that even if some states lost all abortion providers due to legislative policies, the impact on population measures of birth and abortion rates would be small as most women would travel to states with abortion services.

    Toxoplasma gondii is a protozoan parasite that can infect all warm-blooded animals. Sheep and cattle show different susceptibilities to T. gondii infection. Primary infection in pregnant sheep can result in abortion or the birth of weak lambs but they are then protected against further challenge by the development of an effective immunity. Cattle on the other hand can be readily infected, but abortion or perinatal mortality have not been recorded. The evidence suggests that cattle develop a more effective immune response to T. gondii infection than sheep. Potential mechanisms to explain these differences are discussed in this paper.

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

  2. The abortion debate in South Africa.

    PubMed

    Rees, H

    1991-01-01

    Before 1975 abortion was illegal in South Africa unless the life of the mother was at risk. The Abortion and Sterilization Act (ASA) of 1975 broadened the scope of legal abortion. The act allows abortion to save the life of the mother, in cases of severe fetal deformity, in cases or rape or incest, or if the woman is mentally incompetent. The procedure to get the abortion includes finding a doctor to recommend the procedure, then finding 2 other doctors to claim, in good faith, that abortion is indicated. At least 1 of these doctors must have been practicing for 4 years and neither can participate in the procedure. The operation must take place in a state controlled institution or an institution specifically designed for abortion. This law is currently not serving the needs of the women of South Africa, even among the women who are legally entitled to have an abortion. Annually only 40% of those that apply for abortion are approved and over 70% of the approved procedures are performed on psychological grounds. It is estimated that there are 200,000-300,000 illegal abortions every year. At Baragwanath there are 15,000 patients admitted for infection related to abortion every year. The ASA has failed to stop illegal abortion and failed to meet the needs of society. The abortion law should be liberalized for a variety of reasons. Women do not have adequate access to contraceptives in South Africa. This results in the birth of many unwanted children which are more likely to be abused and abandoned. Even if contraceptives were universally available, they all have associated failure rates. Since it is assumed that a women using contraceptives does not want to become pregnant, abortion needs to be available as a backup to contraceptives. Since South Africa is a patriarchal society, women must be given control over their reproduction if they are to achieve equal status. Thus for the reasons of preventing unwanted and unwanted and abused children, backing up contraceptives

    The subject of abortion is fraught with politics, emotions, and misinformation. A widespread practice reaching far back in history, abortion is again in the news. Psychiatry sits at the intersection of the religious, ethical, psychological, sociological, medical, and legal facets of the abortion issue. Although the religions that forbid abortion are more prominent in the media, many religions have more liberal approaches. While the basic right to abortion has been upheld by the U.S. Supreme Court, several limitations have been permitted, including parental notification or consent (with the possibility of judicial bypass) for minors, waiting periods, and mandatory provision of certain, sometimes biased, information. Before the Roe v. Wade decision legalizing abortion in 1973, many women were maimed or killed by illegal abortions, and psychiatrists were sometimes asked to certify that abortions were justified on psychiatric grounds. Currently, there are active attempts to convince the public and women considering abortion that abortion frequently has negative psychiatric consequences. This assertion is not borne out by the literature: the vast majority of women tolerate abortion without psychiatric sequelae. The psychiatric outcome of abortion is best when patients are able to make autonomous, supported decisions. Psychiatrists need to know the medical and psychiatric facts about abortion. Psychiatrists can then help patients prevent unwanted pregnancies, make informed decisions consonant with their own values and circumstances when they become pregnant, and find appropriate social and medical resources whatever their decisions may be.

    The National Congress in Brazil is currently considering 9 abortion bills, 2 of which were introduced by women. In this interview, the women senators--Jandira Feghall of the Communist Party and Eva Blay of the Social Democrat Party--discuss the likely outcome of the abortion debate. Although the Roman Catholic Church has announced its intentions to oppose any liberalization of the abortion law, there are divisions within the Church as evidenced by the existence of groups such as Catholics for a Free Choice. Both senators agree that decriminalization of abortion will depend upon the societal response and an effort must be made to reach the many people who are confused and undecided about the issue. Although the present debate fits within the broader current debate on population policies, it has been the insistence of the feminist movement that put abortion reform on the agenda. Blay's bill calls for the legalization of abortion on demand until the 12th week of pregnancy and in cases of rape or risk to the woman's life after that point. A controversial aspect of Feghall's bill is the inclusion of maternal human immunodeficiency virus (HIV) infection as a condition for abortion. Feghall notes that this is an option rather than a requirement, but she will eliminate this condition if it engenders discrimination against HIV-infected women. PMID:12318722

    A law legalizing abortion was passed nearly 20 years ago in Czechosl ovakia. The law aimed to give women the freedom to decide for themselves whether they want to be pregnant and to decrease the dangers of illegal abortion. The law resulted in a decreased number of abortions and of complications and deaths associated with abortion. Fertility in the country also declined. In 1968 there were more abortions than live births in the country. Since 1957, the law has been modified. The law still aims to prevent the birth of defective children and to protect the life and health of mothers. Each application for abortion is now examined on its own merits. Favorable economic circumstances, prolife social policies adopted by the government, and the new stricter interpretation of the abortion law have resulted in a r ising birthrate since 1969. Contraception is still stressed as preferab le to abortion. PMID:12256872

    Recent proposed federal legislation banning certain abortion procedures, particularly intact dilatation and extraction, would modify the US Criminal Code such that physicians performing these procedures would be liable for monetary and statutory damages. Clarification of medical procedures is important because some of the procedures used to induce abortion prior to viability are identical or similar to postviability procedures. This article reviews the scientific and medical information on late-term abortion and late-term abortion techniques and includes data on the prevalence of late-term abortion, abortion-related mortality and morbidity rates, and legal issues regarding fetal viability and the balance of maternal and fetal interests. According to enacted American Medical Association (AMA) policy, the use of appropriate medical terminology is critical in defining late-term abortion procedures, particularly intact dilatation and extraction, which is a variant of but distinct from dilatation and evacuation. The AMA recommends that the intact dilatation and extraction procedure not be used unless alternative procedures pose materially greater risk to the woman and that abortions not be performed in the third trimester except in cases of serious fetal anomalies incompatible with life. Major medical societies are urged to collaborate on clinical guidelines on late-term abortion techniques and circumstances that conform to standards of good medical practice. More research on the advantages and disadvantages of specific abortion procedures would help physicians make informed choices about specific abortion procedures. Expanded ongoing data surveillance systems estimating the prevalence of abortion are also needed. PMID:9728645

High recurrence rates and increasing antimicrobial resistance among uropathogens threaten to greatly increase the economic burden of these infections. In this Review, we discuss how basic science studies are elucidating the molecular details of the crosstalk that occurs at the host–pathogen interface, as well as the consequences of these interactions for the pathophysiology of UTIs.

    Substantial legal barriers to abortion persist in both the Irish Republic and Northern Ireland, despite growing popular support for abortion under certain conditions. A 1983 amendment to the republic's constitution guarantees the fetus the same right to life s the mother and bans the provision of information on abortion. Although a recent well publicized case of a pregnant, suicidal 14-year-old who travelled to England for an abortion resulted in an Irish Supreme Court ruling that abortion was acceptable in cases of "real and substantial risk" to a woman's life, uncertainty still surrounds the right to travel to England for the procedure. In Northern Ireland, the 1967 Abortion Act does not apply and abortions are denied even in cases of rape and incest. A total of 1766 women from Northern Ireland and 4158 from the republic travelled to England for abortions in 1991. Public opinion seems to have shifted toward support for less restrictive abortion laws, however. Whereas 80% of those surveyed in a 1980 Irish poll supported to ban on abortion in all cases, this statistic had dropped to 30% by 1990. Similarly, a 1991 poll taken in Northern Ireland found 80% of respondents to be a favor of abortion in cases where the procedure is necessary to maintain a woman's physical or mental health.

    In 1980 and 1981, there were 446,430 legal abortions performed in Italy. There were about 345 legal abortions per 1,000 live births in 1980 and 363 in 1981. About 1.6 percent of women aged 15-49 obtained abortions in both years. An analysis of the characteristics of Italian women who obtained abortions indicates that most were married (about 70 percent), aged 18-36 (74 percent), had had less than a high school education (74 percent) and had had at least one previous live birth (70-75 percent). In 1981, 88 percent of abortions were obtained in public hospitals; 58 percent were carried out at eight or fewer weeks of gestation; and 78 percent were performed under general anesthesia. Only 20 percent were performed without an overnight stay in the hospital; and over 40 percent of women were hospitalized for two days or longer. Infection after the abortion was reported in only 0.03 percent of cases in 1981, and hemorrhage was reported in only 0.27 percent. In 1981, between 43 percent and 84 percent of gynecologists (depending on the region of the country) declined to perform abortions on grounds of conscience. PMID:3872230

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

    Brahams summarizes a 1989 Quebec Court of Appeal decision in an abortion case and places the ruling in the context of worldwide trends in abortion regulation. In Tremblay v. Daigle (1989 Jul 26), the Quebec court upheld a lower court injunction banning a woman from having an abortion. The injunction had been obtained by the woman's former boyfriend, the putative father. Brahams discusses the current legal status of abortion in Canada, the Daigle court's reasoning, and how the British approach to the legal status of fathers and fetuses in abortion disputes differs from the Canadian.

    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

    On May 28, 1978, the Italian senate passed a law legalizing abortions. The law, passed against the will of the Christian Democrat party and the Vatican, is the most liberal in Western Europe. Any woman 18 or older is free to seek an abortion at a private or public institution during the first 90 days of pregnancy. Abortions can be sought on health, economic, social, family, or psychological grounds. A woman requests an abortion at a hospital or clinic, or from a physician. If termination is deemed urgent, the procedure may be performed immediately. If a request is denied, a woman may make another request 7 days later. Second trimester abortions are permitted only if grave danger to the woman or deformation of the fetus is suspected. Women under 18 meed the permission of their parents or legal guardians; a court may also grant permission. Passage of the law has facilitated open debate on the legal and medical aspects of abortion. It has also guaranteed women access to abortions. Physicians, who on grounds of conscience feel they can't perform abortions, may register to be exempt from having to perform them. They may not, however, deny a woman care before and after her abortion, and if they perform the procedure even once, their name is removed from the exempt register. Additionally, all physicians are bound to attempt to preserve the life of all women as well as any fetus which shows life outside the womb. PMID:445601

    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. PMID:25715152

    Psychologists and marriage counselors conducting preabortion interviews in a French clinic note that women have emotions concerning abortion apart from the reasons they give for choosing to end their pregnancies. Their experience demonstrates that a pregnancy never occurs by chance, but always at a given moment of existence. An abortion becomes an event in the significant and particular history of each woman undergoing one. Particular circumstances of unemployment, illness, or other adversity become linked in the woman's later recollections of the abortion. Abortions often signify psychic problems of separation or loss, as demonstrated by the considerable number of immigrant women who undergo abortions after having been obliged to leave their native lands, or those who undergo abortions after the death of a child. Women choosing abortion experience anguish and guilt. Fantasies of the aborted child represent the period of mourning that must be surmounted. The psychic labor of the grief process allows a progressive detachment to be achieved. The belief that expanded knowledge and use of contraception would lead to a significant decline in abortion has been belied by experience; the number of abortions has been stable over the years despite ever increasing use of contraceptives of all types. The objective of contraception, a harmonious sexual relationship in which pregnancy does not occur, is itself complex. Choices related to a more or less distant future are made by individuals who are to a greater or lesser extent engaged in the relationship using more or less inconvenient techniques. Statements made by couples themselves perfectly reflect the paradoxes. Objections and resistances to contraceptive use are also prompted by societal norms of sex and reproduction. The couple are influenced in their abortion decision by their own level of maturity and by their family backgrounds. PMID:8009399

    Infectious diseases, in which pathogens invade and colonize host cells, are responsible for one third of all mortality worldwide. Host cells use special proteins (immunoproteins) and other molecules to fight viral and bacterial invaders. The mechanisms by which immunoproteins enable cells to reduce bacterial loads and survive infections remain unclear. Moreover, during infections, some immunoproteins are known to alter the cytoskeleton, the structure that largely determines cellular mechanical properties. We therefore used an optical stretcher to measure the mechanical properties of primary immune cells (bone marrow derived macrophages) during bacterial infection. We found that macrophages become stiffer upon infection. Remarkably, macrophages lacking the immunoprotein, NLR-C4, lost the stiffening response to infection. This in vitro result correlates with our in vivo data whereby mice lacking NLR-C4 have more lesions and hence increased bacterial distribution and spread. Thus, the immune-protein-dependent increase in cell stiffness in response to bacterial infection (in vitro result) seems to have a functional role in the system level fight against pathogens (in vivo result). We will discuss how this functional link between cell mechanical properties and innate immunity, effected by actin polymerization, reduces the spread of infection.

    Pregnancy is a transient immuno-compromised condition which has evolved to avoid the immune rejection of the fetus by the maternal immune system. The altered immune response of the pregnant female leads to increased susceptibility to invading pathogens, resulting in abortion and congenital defects of the fetus and a subnormal response to vaccination. Active vaccination during pregnancy may lead to abortion induced by heightened cell mediated immune response. In this study, we have administered the highly attenuated vaccine strain DeltapmrG-HM-D (DV-STM-07) in female mice before the onset of pregnancy and followed the immune reaction against challenge with virulent S. Typhimurium in pregnant mice. Here we demonstrate that DV-STM-07 vaccine gives protection against Salmonella in pregnant mice and also prevents Salmonella induced abortion. This protection is conferred by directing the immune response towards Th2 activation and Th1 suppression. The low Th1 response prevents abortion. The use of live attenuated vaccine just before pregnancy carries the risk of transmission to the fetus. We have shown that this vaccine is safe as the vaccine strain is quickly eliminated from the mother and is not transmitted to the fetus. This vaccine also confers immunity to the new born mice of vaccinated mothers. Since there is no evidence of the vaccine candidate reaching the new born mice, we hypothesize that it may be due to trans-colostral transfer of protective anti-Salmonella antibodies. These results suggest that our vaccine DV-STM-07 can be very useful in preventing abortion in the pregnant individuals and confer immunity to the new born. Since there are no such vaccine candidates which can be given to the new born and to the pregnant women, this vaccine holds a very bright future to combat Salmonella induced pregnancy loss.

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

    Countries are grouped by the nature and extent of access to legal abortion. The categories include abortion on demand, for social reasons, for health reasons, for rape or incest or to save a mother's life, and only to save a mother's life. Abortion on demand is available for about 40% of the world's population and may have restrictions, such as parental consent or approval of state committees or physicians. There are 22 countries in Europe, 12 in the former Soviet Union, four in Asia, four in the Americas, one in the Middle East (Turkey), and one in Africa (Tunisia) which provide access to early abortion on demand. Abortion for social and economic reasons is available to 21% of the world's population in five countries in Asia, three in Europe (Great Britain, Finland, and Hungary), and one in Africa (Zambia). Abortion for health reasons is available to 16% of the world's population located in 21 countries in Africa, eight in the Americas, seven in Asia, five in Europe, and four in the Middle East. Laws governing about 5% of the world's population permit abortion only in the case of rape, incest, or when a mother's life is in danger (Brazil, Mexico, and Sudan). 18% of the world's population is covered by laws which permit an abortion only when a mother's life is in danger; this includes 19 countries in Africa, 11 in the Americas, nine in Asia, seven in the Middle East, and one in Europe (Ireland).

    PubMed

    Devine, P E

    1997-01-01

    The introduction to this essay, which presents and defends the "conservative" position on abortion, explains that this position holds that 1) abortion is wrong because it destroys the fetus; 2) the fetus has full personhood from conception (or very near conception); 3) abortion is only justified under special circumstances, such as when the pregnancy poses a threat to the woman's life; and 4) these conclusions should be reflected in law and public policy. Part 2 sets forth the moral foundations for this position. The third part considers the status of the fetus and reviews the various arguments that have been forwarded to resolve the question, such as the species principle, the potentiality principle, the sentience principle, and the conventionalist principle. Part 4 applies the conservative position to problems posed by hard cases, determines that abortion is a form of homicide from two weeks after fertilization (at the latest), reviews circumstances in which various legal definitions of homicide are applicable, argues for the denial of abortion funding by the state, and notes that violent militancy is not the appropriate response to a belief that abortion should be illegal. Section 5 refutes objections to the conservative position based on the fact that some opponents of abortion also oppose contraception, based on feminist ideals, and based on calls for religious freedom in a pluralistic society. In conclusion, the labels applied to the abortion debate are examined, and it is suggested that "communitarian" is the best term for the conservative position. PMID:12348327

    Sir Dugald Baird sketches the history of abortion legislation in Great Britain from the beginning of the century. In his views the 1967 Abortion Act has been one of the most important and beneficial pieces of social legislation enacted in Britain in the last 100 years. It has, however, brought problems both of administration in the hospitals and to individual doctors and nurses, particularly when the patients are young single women and even schoolgirls. One of the consequences of the Abortion Act has been a fall in maternal mortality and perinatal mortality rates. Abortion does not seem to be followed by serious emotional sequelae. Nevertheless recent changes in sexual mores have introduced new and serious social problems which are discussed in relation to the role of the doctor in his relationship with patients seeking abortion.

    1985-01-01

    This review of abortion history considers sacred and secular practice and traces abortion in the US, the legacy of the 19th century, and the change that occurred in the 20th century. Abortion has been practiced since ancient times, but its legality and availability have been threatened continuously by forces that would denigrate women's fundamental rights. Currently, while efforts to decrease the need for abortion through contraception and education continue, access to abortion remains crucial for the well-being of millions of women. That access will never be secure until profound changes occur in the whole society. Laws that prohibit absolutely the practice of abortion are a relatively recent development. In the early Roman Catholic church, abortion was permitted for male fetuses in the first 40 days of pregnancy and for female fetuses in the first 80-90 days. Not until 1588 did Pope Sixtus V declare all abortion murder, with excommunication as the punishment. Only 3 years later a new pope found the absolute sanction unworkable and again allowed early abortions. 300 years would pass before the Catholic church under Pius IX again declared all abortion murder. This standard, declared in 1869, remains the official position of the church, reaffirmed by the current pope. In 1920 the Soviet Union became the 1st modern state formally to legalize abortion. In the early period after the 1917 revolution, abortion was readily available in state operated facilities. These facilities were closed and abortion made illegal when it became clear that the Soviet Union would have to defend itself against Nazi Germany. After World War II women were encouraged to enter the labor force, and abortion once again became legal. The cases of the Catholic church and the Soviet Union illustrate the same point. Abortion legislation has never been in the hands of women. In the 20th century, state policy has been determined by the rhythms of economic and military expansion, the desire for cheap

    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. PMID:3916607

    Several enzymes and metabolites concerned with carbohydrate metabolism were examined in mice infected with Listeria monocytogenes. Liver glycogen and glucose decreased parallel to severity of infection. The concentration of glucose in the blood fell to abnormally low levels with a hypoglycemia being most evident at 72 hr. There was a significant decrease in the activity of hepatic uridine diphosphate glucose-glycogen transglucosylase. This decrease in enzymatic activity correlated with the rate of glycogen depletion. Phosphorylase activity declined in a similar fashion, contraindicating enhanced glycogenolysis as the mechanism responsible for glycogen depletion. Although glucose-6-phosphatase decreased throughout the infection period, it did not appear to be the major metabolic defect causing hypoglycemia in Listeria-infected mice. Further distortion of carbohydrate metabolism was indicated by findings of increased levels of pyruvate and lactate in the blood of infected animals. PMID:4289850

    During the RHIC Au-run in 2001 the 200 MHz storage cavity system was used for the first time. The rebucketing procedure caused significant beam debunching in addition to amplifying debunching due to other mechanisms. At the end of a four hour store, debunched beam could account for approximately 30%-40% of the total beam intensity. Some of it will be in the abort gap. In order to minimize the risk of magnet quenching due to uncontrolled beam losses at the time of a beam dump, a combination of a fast transverse kicker and copper collimators were used to clean the abort gap.

    The enactment of the Eugenic Protection Act in Japan was followed by many changes. The population explosion was stemmed, the birth rate was halved, and while the marriage rate remained steady the divorce rate declined. The annual total of abortions increased until 1955 and then slowly declined. The highest incidence of abortions in families is in the 30 to 34 age group when there are four children in the family. As elsewhere abortion in advanced stages of pregnancy is associated with high morbidity and mortality. There is little consensus as to the number of criminal abortions. Reasons for criminal abortions can be found in the legal restrictions concerning abortion: Licensing of the abortionist, certification of hospitals, taxation of operations and the requirement that abortion be reported. Other factors are price competition and the patient's desire for secrecy. Contraception is relatively ineffective as a birth control method in Japan. Oral contraceptives are not yet government approved. In 1958 alone 1.1 per cent of married women were sterilized and the incidence of sterilization was increasing. PMID:6062283

    In Planned Parenthood vs. Casey, the US Supreme Court upheld all but 1 provision of Pennsylvania law that further restricts access to abortion. The law has a 24-hour waiting period, parental consent for minors with a judicial bypass, husband notification, and the circumstances of each abortion are to be reported to the state for statistical purposes. The Court overturned the husband notification provision even though it had a bypass procedure. The most important aspect of the decision was the change from the strict scrutiny in which abortion was to be left alone unless the state could show a compelling need to regulate it to an undue burden test in which the state is allowed to regulate abortion so long as it does not place an undue burden on women trying to seek abortion services. The 24-hour waiting period was upheld; however, it was also acknowledged that since 83% of women live in counties without abortion services, this may turn out to be an undue burden and it is open to review at later date when statistical evidence is available. The Opinion was written by Justices O'Connor, Kennedy, and Souter. Chief Justice Rehnquist and Justices Scalia, White, and Thomas dissented saying that the undue burden standard was unprecedented in constitutional law and undefinable in practice. It is likely now that the Court will begin writing abortion policy as it clarifies each specific point of the law rather than ruling on fundamental legal principles. PMID:1351612

    Abortion is called the invisible plague of all countries and cultures in the twentieth century. It is by far the most important method of birth control in the world today. For every 200 babies born there are at least 100 abortions. In the rich world, a woman who wants to end her pregnancy goes to an abortionist, but for millions of poor women, abortion happens spontaneously in their own homes induced by poor nutrition, sheer physical weakness, and too many pregnancies too close together. In countries where abortion is illegal, millions of women die each year as a result of severe illness or the botched handiwork of backyard operators. The most common complications are massive hemorrhaging, perforation of the uterus, laceration, sepsis, and renal failure. The experience of a great many countries shows that simply legalizing abortion can lead to a dramatic drop in death and illness. Relaxation of abortion laws can save lives, money, and misery for mothers and children. Illegal abortion has become a major problem in Africa there are 3 main types of women who enter hospitals with complications after abortions: 1) the teenager who is away from home; 2) the young woman, often educated, working, and with financial responsibilities, who is ambitious for herself, her husband, or her family; and 3) the woman in her thirties, illiterate, a rural worker, married most of her reproductive life, and pregnant most years. The third type of woman may abort because her system is utterly depleted. Such women must be shown that there is a good chance of survival for her children so that she will not have so many.

    PubMed Central

    2014-01-01

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

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

The questionnaire contains 80 questions gathering information on socieconomic data, on medical history, on the procedure of the intervention, and on the follow-up visit. A study done on 5700 questionnaires filled between 1976 and 1977 show that most abortion seekers belong to the middle class, and that pregnancy was due in 20% of cases to pill failure, and in 34% of cases to failure of behavioral methods, or to lack of contraception. 88% of patients declared themselves satisfied with the procedure.

    Induced abortion is one of the most difficult sociomedical problems facing the Indonesian government. While well-known in traditional society, the practice was discouraged by all Indonesian religious groups, and forbidden by the Dutch colonial authorities. Although abortion was technically illegal under the criminal code, a judicial interpretation in the early 1970s permitted medical professionals to offer the procedure so long as they were discreet and careful. The numbers of medical abortions carried out in Indonesia rose dramatically, and there was evidence of matching declines in the incidence of morbidity and mortality caused by dangerous illegal procedures. Medical and community groups campaigned for a more liberal abortion law to protect legal practitioners and stamp out illegal traditional practices. Their efforts appeared to bear fruit in the draft Health Law, but when the law was passed by the legislature in late 1992, the issue was again clouded by contradictions and inconsistencies.

    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. PMID:25702076

    The Penal Code (Amendment) Bill or the abortion bill has the objective of liberalizing the current law on the regulation of abortion. Abortion had been strictly prohibited and carried stiff penalties. Anyone who attempted to assists a woman to procure an abortion could be liable to 7 years' imprisonment. However, medical abortions were distinguished as being medically determined to save the health of the mother. Demands for a reevaluation of the law came from the medical profession, and in response the Minister for Presidential Affairs submitted a bill to Parliament in November, 1990. The expressed government rationale for these proposed amendments was concern about the health of women. In Botswana about 200 women die yearly because of pregnancy. According to the proposed law: an abortion could be carried out within the first 16 weeks of pregnancy if: 1) the pregnancy were a result of rape, incest, or defilement (the impregnation of a girl aged 16 or less, the impregnation of imbeciles or idiots), 2) the physical or mental health of the woman were at risk because of the pregnancy, 3) the child would be born with a serious physical or mental abnormality. The abortion could be carried out only if 2 medical doctors approved it. The amendments fall far short of increasing women's control over their bodies. The Botswana Christian Council issued a statement early in the public debate. While it did not oppose the bill in its entirety, clear concern was expressed concerning the apparent right of determining who lives and who dies depending on the handicap of the child. This rather liberal position was challenged by the Roman Catholic Church which interpreted abortion as the murder of God-given life. The bill was nevertheless passed by Parliament in September 1991, and the President signed it on October 11, 1991. PMID:12288837

    Summary: Anaplasma phagocytophilum persists in nature by cycling between mammals and ticks. Human infection by the bite of an infected tick leads to a potentially fatal emerging disease called human granulocytic anaplasmosis. A. phagocytophilum is an obligatory intracellular bacterium that replicates inside mammalian granulocytes and the salivary gland and midgut cells of ticks. A. phagocytophilum evolved the remarkable ability to hijack the regulatory system of host cells. A. phagocytophilum alters vesicular traffic to create an intracellular membrane-bound compartment that allows replication in seclusion from lysosomes. The bacterium downregulates or actively inhibits a number of innate immune responses of mammalian host cells, and it upregulates cellular cholesterol uptake to acquire cholesterol for survival. It also upregulates several genes critical for the infection of ticks, and it prolongs tick survival at freezing temperatures. Several host factors that exacerbate infection have been identified, including interleukin-8 (IL-8) and cholesterol. Host factors that overcome infection include IL-12 and gamma interferon (IFN-γ). Two bacterial type IV secretion effectors and several bacterial proteins that associate with inclusion membranes have been identified. An understanding of the molecular mechanisms underlying A. phagocytophilum infection will foster the development of creative ideas to prevent or treat this emerging tick-borne disease. PMID:21734244

    For a long time in human history, global population growth was checked by infant mortality, which ranged from 30-50% and did not start sinking until the beginning of the 1800s in the west. Child murder in the west was prohibited by law around the 1100-1200s, but it continued secretly. Among private people, induced abortion was allowed. In the holy scripts of Hinduism and Brahminism, abortion was prohibited. Hippocrates wrote that doctors should not give women abortifacient. The church father Augustinus stated that it was not within human power to discern when the soul entered the body, a circumstance that forbid abortion. A church meeting in 305 A.D. distanced itself from abortion, and this has been the stand of the Catholic Church ever since. In Sweden, exposing a child to the elements was practiced until the end of the 1200s, when it became prohibited. Protestants punished child murder by death. During 1759-78, 217 women were executed for child-killing. From the 1400s, church law punished abortion, and later, capital and punishment was meted out for it, but a distinction was made if the fetus was alive or stillborn. The law in 1734 punished abortion by the death of all concerned. The death penalty was abolished in 1864. In 1896, Anna Linholm reported to the policy in Uppsala that a midwife had been practicing clandestine abortions. Some of her patients were admitted to hospital for hemorrhaging. She was sentenced to hard labor. During 1851-1903, a total of 1408 abortions were reported to the health service. 90% of these became known because of death caused by obduction. Phosphorus was used for abortion in 1271 cases, arsenic in 62, and mechanical aids in 8 cases. About 1//2 of all female suicides at the end of the 1800s was performed by pregnant women who ate phosphorus. Almost all were unmarried, and 56% carried it out after the 5th month of pregnancy. In 1901, phosphorus was prohibited in Swedish homes. In 1875, free abortions became available. However, the

    Infection with the human immunodeficiency virus (HIV) results in a profound immunosuppression due predominantly to a selective depletion of helper/inducer T lymphocytes that express the receptor for the virus (the CD4 molecule). HIV also has tropism for the brain leading to neuropsychiatric abnormalities. Besides inducing cell death, HIV can interfere with T4 cell function by various mechanisms. The monocyte serves as a reservoir for HIV and is relatively refractory to its cytopathic effects. HIV can exist in a latent or chronic form which can be converted to a productive infection by a variety of inductive signals.

    The objective of this study was to evaluate the influence of exposure to oil and oil products among men on the time taken for their wives to conceive and on the incidence of spontaneous abortion among them. A cross-sectional study was performed by posting questionnaires to 1,269 men employed as offshore mechanics, offshore operators, offshore drilling personnel, car mechanics (the 'exposed' occupations) and carpenters ('unexposed'). The married men were asked to give a separate questionnaire to their wives for details about their pregnancies. The time elapsed between the beginning of coitus without contraception and the wife becoming pregnant (time to pregnancy) was analyzed with Cox regression analysis by calculating fecundability ratios for the pregnancies for the men exposed to oil and oil products as compared with the men who were not exposed. Spontaneous abortions were analyzed with logistic regression by calculating odds ratios for the pregnancies in which the men were exposed vs. not exposed. A total of 741 (58%) men returned the questionnaires. A total of 301 pregnancies were analyzed for time taken to conceive and 580 for spontaneous abortion. The results were adjusted for variables that could significantly influence conception time (previous infections of the reproductive system and coffee drinking) or the incidence of spontaneous abortion (mother's age, parity and smoking). The outcomes between the exposed and unexposed pregnancies showed no significant differences. Car mechanics had a lower fecundability ratio before 1992 than after 1992. Paternal exposure to hydrocarbons in the occupations studied did not seem to have had a major influence on time to conception or the incidence of spontaneous abortion among the wives of the men exposed to oil products.

    Background: Neospora caninum is considered one of the major causes of repeated abortions in livestock. This study aimed to determine the seropositivity to N. caninum using indirect ELISA and the influence of the infection on the occurrence of abortions in selected dairy herd in Slovakia. Method: Blood samples were obtained from 490 cattle over a period of two years and were tested for N. caninum antibodies using indirect ELISA. Results: The presence of specific antibodies in the herd was detected in 118 (24.1%) cows. According to selected groups; 117 (41.0%) cows with a history of abortion, 65 (43.3%) heifers and 223 (2.2%) cows without abortions were tested positive to Neospora. Vertical transmission of N. caninum dominated in examined herd and the relative risk (RR) of dam-daughter seropositivity in progenies of seropositive mothers was 2.1 times higher than in progenies of seronegative dams. Molecular analyses of aborted foetuses of seropositive mothers showed the presence of Neospora DNA. However, 23 (28.1%) of heifers born to seronegative cows were seropositive, indicating also the postnatal transmission of the infection from the environment. Conclusion: Study revealed significant correlation between the presence of specific antibodies and the occurrence of abortions, the risk of abortion in seropositive animals was 3.8 times higher than in seronegative ones. Incorrect farm management contributed to spread and circulation of neosporosis in entire dairy herd what could significantly impair the reproduction and economic parameters of breeding.

    Unsafe abortion in Sudan results in significant morbidity and mortality. This study of treatment for complications of unsafe abortion in five hospitals in Khartoum, Sudan, included a review of hospital records and a survey of 726 patients seeking abortion-related care from 27 October 2007 to 31 January 2008, an interview of a provider of post-abortion care and focus group discussions with community leaders. Findings demonstrate enormous unmet need for safe abortion services. Abortion is legally restricted in Sudan to circumstances where the woman's life is at risk or in cases of rape. Post-abortion care is not easily accessible. In a country struggling with poverty, internal displacement, rural dwelling, and a dearth of trained doctors, mid-level providers are not allowed to provide post-abortion care or prescribe contraception. The vast majority of the 726 abortion patients in the five hospitals were treated with dilatation and curettage (D&C), and only 12.3% were discharged with a contraceptive method. Some women waited long hours before treatment was provided; 14.5% of them had to wait for 5-8 hours and 7.3% for 9-12 hours. Mid-level providers should be trained in safe abortion care and post-abortion care to make these services accessible to a wider community in Sudan. Guidelines should be developed on quality of care and should mandate the use of manual vacuum aspiration or misoprostol for medical abortion instead of D&C. PMID:19962640

    Rhoden's article is one of three on "Abortion: searching for common ground" in this issue of the Hastings Center Report. Her article, together with those by M. Mahowald and M. Glendon, was prompted by the expectation that the impending U.S. Supreme Court decision in Webster v. Reproductive Health Services (3 July 1989) would overturn or restrict Roe v. Wade (1973). Rhoden, an advocate for the pro-choice position, asks whether a compromise leading to an acceptable regulatory policy is possible or desirable among those on opposite sides of the abortion issue. She identifies several reasons why the Roe decision is vulnerable to review, but argues that effective education about sexuality and comprehensive social support of women are better approaches to abortion than restrictive legislation.

    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. PMID:20303830

    The definition of repeated spontaneous abortions is subject to caution. For some, it corresponds to at least three repeated spontaneous abortions with no normal previous pregnancy; for others, it comprises the repeated spontaneous abortions occurring after a normal pregnancy. It is a frequent problem, especially if one tries to give a wider definition. The authors studied the frequency of repeated spontaneous abortions in a continuous series of 14,857 pregnancies which took place between January 1982 and December 1988. In the study of the aetiology of the repeated spontaneous abortions in the various groups of women defined according to the number of previous pregnancies and abortions, they find the classical causes of repeated spontaneous abortions in all the categories: therefore, it seems legitimate to them that a wider definition be given for repeated spontaneous abortions.

    Fowl plague virus-infected cells of Ehrlich ascitic carcinoma produce a noninfectious virus which is defective in fragility of its membranes. An attempt has been made to produce nondefective virus by fusion of infected Ehrlich cells with permissive cells: infected and non-infected chicken fibroblasts. The fusion of FPV-infected and 3H-uridine labeled Ehrlich ascitic carcinoma cells with infected unlabeled chicken fibroblasts using inactivated Sendai virus resulted in production of two types of labeled virus particles: with a buoyant density in cesium chloride gradient of 1.29 g/cm3 characteristic of particles produced by infected Ehrlich cells and buoyant density 1.22 g/cm3 typical of standard influenza virus. Both types of particles has infectious activity which was greater in the virus with the density of 1.22 g/cm3. However, particles with the density of 1.22 g/cm3 are not found upon the fusion of infected Ehrlich cells with uninfected chicken fibroblasts, with chicken fibroblasts early after infection, or with chicken fibroblasts treated with actinomycin D before infection. Infected chicken fibroblasts in hybrids were shown not to use the radioactive pool of Ehrlich cells and, accordingly, the virus with the density of 1.22 g/cm3 if formed from components pre-existing in Ehrlich cells. It is suggested that the standard virus buds on the areas of membranes of permissive cells which are parts of the hybrids. PMID:200012

    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.

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

    Apoptosis has been postulated to play an important role during feline infectious peritonitis virus (FIPV) infection; however, its mechanism is not well characterized. This study is focused on apoptosis and transcriptional profiling of FIPV-infected cells following in vitro infection of CRFK cells with FIPV 79-1146 WSU. Flow cytometry was used to determine mode of cell death in first 42 h post infection (hpi). FIPV infected cells underwent early apoptosis at 9 hpi (p < 0.05) followed by late apoptosis at 12 hpi (p < 0.05) and necrosis from 24 hpi (p < 0.05). Then, next generation sequencing was performed on 9 hpi and control uninfected cells by Illumina analyzer. An aggregate of 4546 genes (2229 down-regulated and 2317 up-regulated) from 17 cellular process, 11 molecular functions and 130 possible biological pathways were affected by FIPV. 131 genes from apoptosis cluster (80 down-regulated and 51 up-regulated) along with increase of apoptosis, p53, p38 MAPK, VEGF and chemokines/cytokines signaling pathways were probably involved in apoptosis process. Six of the de-regulated genes expression (RASSF1, BATF2, MAGEB16, PDCD5, TNFα and TRAF2) and TNFα protein concentration were analyzed by RT-qPCR and ELISA, respectively, at different time-points. Up-regulations of both pro-apoptotic (i.e. PDCD5) and anti-apoptotic (i.e. TRAF2) were detected from first hpi and continuing to deregulate during apoptosis process in the infected cells.

    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. PMID:25815623

    Abstract Objective To determine the location of Canadian abortion services relative to where reproductive-age women reside, and the characteristics of abortion facilities and providers. Design An international survey was adapted for Canadian relevance. Public sources and professional networks were used to identify facilities. The bilingual survey was distributed by mail and e-mail from July to November 2013. Setting Canada. Participants A total of 94 abortion facilities were identified. Main outcome measures The number and location of services were compared with the distribution of reproductive-age women by location of residence. Results We identified 94 Canadian facilities providing abortion in 2012, with 48.9% in Quebec. The response rate was 83.0% (78 of 94). Facilities in every jurisdiction with services responded. In Quebec and British Columbia abortion services are nearly equally present in large urban centres and rural locations throughout the provinces; in other Canadian provinces services are chiefly located in large urban areas. No abortion services were identified in Prince Edward Island. Respondents reported provision of 75 650 abortions in 2012 (including 4.0% by medical abortion). Canadian facilities reported minimal or no harassment, in stark contrast to American facilities that responded to the same survey. Conclusion Access to abortion services varies by region across Canada. Services are not equitably distributed in relation to the regions where reproductive-age women reside. British Columbia and Quebec have demonstrated effective strategies to address disparities. Health policy and service improvements have the potential to address current abortion access inequity in Canada. These measures include improved access to mifepristone for medical abortion; provincial policies to support abortion services; routine abortion training within family medicine residency programs; and increasing the scope of practice for nurses and midwives to include abortion

    At R.G. Kar Medical College Hospital, Calcutta, 10 cases of septic abortion from 1975-1977 were studied. Hysterectomies were preformed on 4 cases due to emergency situations including traumatised uterine fundus and perforated cervix, and on 6 cases after conservative treatment. Upon performing laparotomy in 9 cases, a uterine rent was detected; in 1 case there was a perforation in the posterior wall of the cervix, and in 5 cases mechanical obstructions due to internal adhesions to the uterine rent were found. 4 patients died primarily because of the patients seeking help too late. It is suggested that under high risk circumstances, laparotomy is advantageous to conservative medical management since bowel injuries and mechanical obstructions can only be detected by laparotomy. Radical surgery, however, should be undertaken before the patients general condition deteriorates to the point that the patient cannot tolerate surgical intervention. PMID:12336028

    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.

In recent decades, a measure of societal tolerance has led to decriminalize and legalize abortion in accordance with one of two models: a more restricted and conservative model known as therapeutic abortion, and the model that accepts voluntary abortion within the first trimester of pregnancy. Liberalization of abortion aims at ending clandestine abortions and decriminalizes the practice in order to increase reproductive education and accessibility of contraceptive methods, dissuade women from interrupting their pregnancy and, ultimately, make abortion a medically safe procedure within the boundaries of the law, inspired by efforts to reduce the incidence of this practice. The current legal initiative to decriminalize abortion in Chile proposes a notably rigid set of indications which would not resolve the three main objectives that need to be considered: 1) Establish the legal framework of abortion; 2) Contribute to reduce social unrest; 3) Solve the public health issue of clandestine, illegal abortions. Debate must urgently be opened to include alternatives in line with the general tendency to respect women's decision within the first trimester of pregnancy. PMID:26057783

  10. The Politicization of Abortion and the Evolution of Abortion Counseling

    PubMed Central

    2013-01-01

    The field of abortion counseling originated in the abortion rights movement of the 1970s. During its evolution to the present day, it has faced significant challenges, primarily arising from the increasing politicization and stigmatization of abortion since legalization. Abortion counseling has been affected not only by the imposition of antiabortion statutes, but also by the changing needs of patients who have come of age in a very different era than when this occupation was first developed. One major innovation—head and heart counseling—departs in significant ways from previous conventions of the field and illustrates the complex and changing political meanings of abortion and therefore the challenges to abortion providers in the years following Roe v Wade.

    The issue of abortion is discussed with reference to the claim that people have a right of control over their own bodies. Do people "own" their own bodies? If so, what would be entailed? These questions are discussed in commonsense terms and also in relation to the jurisprudence of Hohfeld, Honore, Munzer and Waldron. It is argued that whether or not women are morally and/or should be legally entitled to have abortions, such entitlements cannot be derived from a general moral entitlement to do what we will with our own bodies since there is no such entitlement. Whether or not we "own" them, we can have rights duties, liabilities, restrictions and disadvantages as well as rights concerning our own bodies. PMID:9220332

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

    Four volunteers with naturally acquired, culture-proved influenza A infection inhaled a radiolabeled aerosol to permit investigation of lung mucociliary clearance mechanisms during and after symptomatic illness. Mucus transport in the trachea was undetectable when monitored with an external multidetector probe within 48 hours of the onset of the illness, but was found at a normal velocity by 1 week in three of the four subjects. In two volunteers who coughed 23 to 48 times during the 4.5-hour observation period, whole lung clearance was as fast within the first 48 hours of illness as during health 3 months later in spite of the absence of measurable tracheal mucus transport. Conversely, in spite of the return 1 week later of mucus transport at velocities expected in the trachea, whole lung clearance for the 4.5-hour period was slowed in two volunteers who coughed less than once an hour. The data offer evidence that cough is important in maintaining lung clearance for at least several days after symptomatic influenza A infection when other mechanisms that depend on ciliary function are severely deficient.

    In a Swiss dairy farm (canton of Geneva) consisting of 73 animals 8 abortions were observed within 2 weeks. Serological and molecular biological analyses (PCR) on aborting dams, and abortion materials, respectively, revealed that the protozoan parasite Neospora caninum was the causative agent. Besides the 8 aborting animals, 12 other non-aborting heifers were found to be serologically positive for this parasite. All positive sera were further tested in an avidity-ELISA to elucidate the recency of infection. All seropositive animals but one showed low avidities at the time the abortion storm started. This indicated at a recent N. caninum-infection within the herd. Thus, the animals most probably were exposed to N. caninum-oocysts (e.g. by dog feces-contaminated forage) and the resulting abortion storm was due to an exogenous (formerly known as "horizontal") parasite transmission into a naive herd. This is the first documented record of such an event in Switzerland. PMID:15801622

    Dendritic cells (DC) play a pivotal role in transmission and dissemination of HIV-1. Earlier studies reported that DC present at the site of infection trap virus particles via DC-SIGN and transfer the virus to the interacting naïve T cells. This prompted us to ask the question whether DC could acquire virus from infected T cells during DC-T cell interaction. To address this, we investigated the likely transfer of virus from HIV-1 infected T cells to DC and the underlying mechanisms involved. Results indicate that DC acquire virus from infected T cells via antigen uptake mechanism and this results in infection of DC with expression of proteins directed by viral DNA. Further studies with HIV-1 lacking the Env protein also resulted in infection of DC. The use of antibodies against DC-SIGN and DC-SIGN-R ruled out a role for receptor in the infection of DC. Additional data show that DC infection is directly correlated with the ability of DC to take up antigen from infected T cells. Overall, these studies provide evidence to suggest that HIV-1, besides infecting immune cells, also utilizes immunological mechanism(s) to acquire and disseminate virus. PMID:19829715

    Over 15 million abortions have been performed in the US since the process of abortion legalization began in 1967. Consequences of legalization have included a marked reduction of pregnancy-related mortality and the prevention in many cases of the birth of infants with major physical or mental defects. Prenatal diagnosis, backed up by selective abortion, has made procreation a possibility for many couples who might otherwise avoid childbearing. However, the number of abortions performed on the basis of prenatal diagnosis remains small, comprising only about .01% of all legal abortions. In recent months, the pro-choice movement in the US has been handed 2 important victories: the US Supreme Court reaffirmed the 1973 decision legalizing abortion and the US Senate defeated a constitutional amendment intended to reverse this decision. As a result of these victories, contributions to pro-choice groups have declined. Continued vigilance is needed to protect these victories. PMID:12267089

    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. PMID:24890742

  19. Dworkin and Casey on abortion.

    PubMed

    Stroud, Sarah

    1996-01-01

    This article responds to two important recent treatments of abortion rights. I will mainly discuss Ronald Dworkin's recent writings concerning abortion: his article "Unenumerated rights: whether and how Roe should be overruled," and his book Life's Dominion. In these writings Dworkin presents a novel view of what the constitutional and moral argument surronding abortion is really about. Both debates actually turn, he argues, on the question of how to interpret the widely shared idea that human life is sacred. At the heart of the abortion debate is the essentially religious notion that human life has value which transcends its value to any particular person; abortion is therefore at bottom a religious issue. Dworkin hopes to use this analysis to show that the religion clauses of the First Amendment provide a "textual home" for a woman's right to choose abortion. I wish to scrutinize this suggestion here; I want to probe the precise consequences for abortion rights of such an understanding of their basis. I will argue that the consequences are more radical than Dworkin seems to realize. The other work I will examine here is the important 1992 Supreme Court decision on abortion, Planned Parenthood v. Casey. The controlling opinion in that case, written jointly by Justices Kennedy, O'Connor, and Souter, strongly reaffirmed Roe v. Wade, but also upheld most of the provisions of a Pennsylvania statute that had mandated various restrictions on abortion. The justices' basis for upholding these restictions was their introduction of a new constitutional standard for abortion regulations, an apparently weaker standard than those that had governed previous Supreme Court abortion decisions. I think there is a flaw in Casey's new constitutional test for abortion regulations, and I will explain, when we turn to Casey, what it is and why it bears a close relation to Dworkin's reluctance to carry his argument as far as it seems to go.

    Wilson, K

    1985-01-01

    At the same time that American women celebrate the freedoms won thus far for so many Americans, American women must realize they face some of the greatest threats to liberty in recent memory. To understand this movement against American women, it is necessary to first understand the roots of the historic movement for women's rights. Reproductive freedom for many years topped the agenda of the modern women's movement. At a time and in a land where rights were being enriched and liberty prized, choice took a prominent role, specifically, the right to abortion but also generally to repdocuctive freedom and the many underlying issues involved. This is why the various efforts to criminalize abortion effect every citizen, because they pose a serious threat to the constitutional rights of each individual. This is the intellectual view, or the "head" argument. The Constitution states that: "Congress shall make no laws respecting an establishment of religion, or prohibiting the free exercise thereof; the enumeration in the Constitution, of certain rights, shall not be construed to deny or disparage others retained by the people; and no state shall make or enforce any laws which shall abridge the privileges or immunities of citizens of the US." Each of these clauses expresses the philosophy on which the Constitution was founded -- individual liberty. While there has been some legitimate disagreement over what constitutes an inalienable right, the concept is clear: the government should not become involved in personal philosophical or religious matters, except to permit the freedom of personal philosophical or religious expression. The anti-abortion contignent makes its case by claiming that a fertilized egg is a cona fide person and should, therefore, be guaranteed the Constitution's full roster of protections. In its landmark Roe v. Wade opinion, the Supreme Court held what pro-choice activities have been claiming for years. Since there is no empirical test by which measure

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

    One hundred and thirty consecutive women were interviewed about the development of psychological symptoms related to induced abortion two days before and four months after the abortion. Sixty-one (47%) participated in the second interview. Of the 61 women, 52% were psychologically influenced before the abortion to an extent which indicated severe crisis or actual psychiatric illness. Four months after the abortion 13 of these women were still psychologically affected. Furthermore, five women who were not affected before the abortion had developed psychological problems. Among ten of these women (16%) the physiological problems could only be related to the circumstance in connection with the abortion. For a number of women (30%) the abortion had a negative influence on their relationships and their sex lives, whereas other claimed that their relationship had become closer because of their reactions towards the abortions. In spite of these conditions all women indicated that their decision about the abortion had been the correct one under the given circumstances. PMID:9206861

    Leishmania amazonensis is an intracellular protozoan parasite responsible for chronic cutaneous leishmaniasis (CL). CL is a neglected tropical disease responsible for infecting millions of people worldwide. L. amazonensis promotes alteration of various signaling pathways that are essential for host cell survival. Specifically, through parasite-mediated phosphorylation of extracellular signal regulated kinase (ERK), L. amazonensis inhibits cell-mediated parasite killing and promotes its own survival by co-opting multiple host cell functions. In this review we highlight Leishmania-host cell signaling alterations focusing on those specific to 1) motor proteins, 2) prevention of NADPH subunit phosphorylation impairing reactive oxygen species production (ROS), and 3) localized endosomal signaling to up-regulate ERK phosphorylation. This review will focus upon mechanisms and possible explanations as to how Leishmania spp. evades the various layers of defense employed by the host immune response. PMID:24838145

    The evolutionary stability of mutualisms is enhanced when partners possess mechanisms to prevent overexploitation by one another. In obligate pollination-seed consumption mutualisms, selective abortion of flowers containing excessive eggs represents one such mechanism, but empirical tests have long been limited to the yucca-yucca moth mutualism. We present evidence for selective abortion in the recently discovered mutualism between Glochidion trees and Epicephala moths. In Glochidion acuminatum, proportion of aborted flowers progressively increased both with higher egg load and increased ovule damage. Selective abortion resulted in a 16% seed production increase compared with expectations under random abortion, and moths suffered fitness losses as high as 62% when ovipositing into pre-infested flowers. Moth eggs were laid singly more often than expected under random oviposition, thus avoiding potential disadvantages from multiple infestations. As new pollination mutualisms are being discovered, selective abortion mechanisms may prove to be more widespread than previously thought. PMID:20113331

    This study was conducted to increase knowledge about the psychosocial background and current living conditions of Swedish women seeking abortion, along with their motives for abortion and their feelings towards pregnancy and abortion. Two hundred and eleven women answered a questionnaire when they consulted the gynaecologist for the first time. The study indicates that legal abortion may be sought by women in many circumstances and is not confined to those in special risk groups. For example, most women in the sample were living in stable relationships with adequate finances. The motives behind a decision to postpone or limit the number of children revealed a wish to have children with the right partner and at the right time in order to combine good parenting with professional career. The study shows that prevailing expectations about lifestyle render abortion a necessity in family planning. One-third of the women had had a previous abortion(s) and 12% had become pregnant in a situation where they had felt pressured or threatened by the man. Two-thirds of the women characterised their initial feelings towards the pregnancy solely in painful words while nearly all the others reported contradictory feelings. Concerning feelings towards the coming abortion, more than half expressed both positive and painful feelings such as anxiety, relief, grief, guilt, anguish, emptiness and responsibility, while one-third expressed only painful feelings. However, almost 70% stated that nothing could change their decision to have an abortion. Thus, this study highlights that contradictory feelings in relation to both pregnancy and the coming abortion are common but are very seldom associated with doubts about the decision to have an abortion.

    In a June 1970 through January 1971 study of 99 single girls seeking abortion and 33 single girls choosing to complete the pregnancy, knowledge of and/or access to contraceptives were not the problem. Emotional factors such as guilt over sexual activity, acting-out disorders (rebellious attitude, hippie lifestyle, indifference toward others), or severe reactions to loss of a love relationship contributed to pregnancy in both groups. The girls who became pregnant, especially the ones who chose to complete the pregnancy, viewed pregnancy and motherhood as a source of gratification and self-esteem. Research on motivational factors in adolescent pregnancy is needed to prevent high recidivism. The majority of state abortion laws requiring phychiatric deficiencies for abortions are misguided, since the girls who chose not to abort were more psychiatrically disturbed than the ones who had abortions.

    A theory on the morality of abortion is derived from the presumption that parents have special moral obligations to nurture their immature children. Three alternative models of the acquisition of parental responsibilities are examined: one based on biological relationships, one based on consent, and one based on causal responsibility. Each of the models is examined in terms of its ability to handle cases involving nonstandard methods of procreation, such as surrogate motherhood, artificial insemination by donor, and embryo transfer. It is concluded that the model based on causal responsibility provides the most adequate criterion for the ascription of parental responsibility toward fetuses. PMID:11650732

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

    We conducted a retrospective cohort study using randomly selected medical charts of women reporting a history of partner violence and women with no history of partner violence at the time of a family planning or abortion appointment (n = 6,564 per group). We analyzed lifetime history of partner violence for odds of lifetime history of abortion and miscarriage number, and birth control problems. To more closely match timing, we analyzed a subsample of 2,186 women reporting current violence versus not at the time of an abortion appointment for differences in gestational age, medical versus surgical method choice, and return for follow-up visit. After adjusting for years at risk and demographic characteristics, women with a past history of partner violence were not more likely to have ever had one abortion, but they were more likely to have had problems with birth control, repeat abortions, and miscarriages than women with no history of violence. Women with current partner violence were also more likely to be receiving an abortion at a later gestational age. We found no differences between the groups in return for abortion follow-up visit or choice of surgical versus medication abortion. Findings support screening for the influence of partner violence on reproductive health and related safety planning. PMID:24580133

    In 1991, the abortion literature was characterized by articles relating to 1) epidemiologic issues in abortion care, 2) advances in knowledge and experience with medical abortifacients such as mifepristone (RU 486), and 3) cervical ripening prior to abortion with the use of both mifepristone and prostaglandins. Technical methods of achieving termination of pregnancy continue to be similar in the United States, the United Kingdom, and Europe, although induction-abortion times are generally slower in Europe than in the United States. Surgically, dilatation and evacuation procedures continue to be more common in the United States than in other countries. The effectiveness of mifepristone is undisputed, and the recommended dose for early first-trimester termination is being compared with lower dose alternative regimens. There is additional evidence that at least in the short term, the negative psychological sequelae of abortion are infrequent and are inconsequential as a public health issue. PMID:1504270

    What role does birth play in the debate about elective abortion? Does the wrongness of infanticide imply the wrongness of late-term abortion? In this paper, I argue that the same or similar factors that make birth morally significant with regard to abortion make meaningful viability morally significant due to the relatively arbitrary time of birth. I do this by considering the positions of Mary Anne Warren and José Luis Bermúdez who argue that birth is significant enough that the wrongness of infanticide does not imply the wrongness of late-term abortion. On the basis of the relatively arbitrary timing of birth, I argue that meaningful viability is the point at which elective abortion is prima facie morally wrong. PMID:25012846

    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

    Articles concerning new aspects of B. anthracis mechanisms of infection were reviewed. It was found, that the hair follicle plays an important role in the spore germination process. The hair follicle represent an important portal of entry in the course of the cutaneous form of disease infections. After mouse exposition to aerosol of spores prepared from B. anthracis strains, an increase in the level of TNF-α cytokines was observed. The TNF-α cytokines were produced after intrusion into the host by the microorganism. This process may play a significant role in the induced migration of infected cells APCs (Antigen Presenting Cells) via chemotactic signals to the lymph nodes. It was explained that IgG, which binds to the spore surface, activates the adaptive immune system response. As a result, the release C3b opsonin from the spore surface, and mediating of C3 protein fragments of B. anthracis spores phagocytosis by human macrophages, was observed. The genes coding germination spores protein in mutant strains of B. anthracis MIGD was a crucial discovery. According to this, it could be assumed that the activity of B. anthracis spores germination process is dependent upon the sleB, cwlJ1 and cwlJ2 genes, which code the GSLEs lithic enzymes. It was also discovered that the specific antibody for PA20, which binds to the PA20 antigenic determinant, are able to block further PA83 proteolytic fission on the surface of cells. This process neutralized PA functions and weakened the activity of free PA20, which is produced during the PA83 enzyme fission process. Interaction between PA63 monomer and LF may be helpful in the PA63 oligomerization and grouping process, and the creation of LF/PA63 complexes may be a part of an alternative process of assembling the anthrax toxin on the surface of cells. It was found that actin-dependent endocytosis plays an important role in the PA heptamerisation process and leads to blocking the toxin activity. Chaperones, a protein derived from

(2000) J Cell Sci 113: 2065-2074] we have shown that overexpression in L. amazonensis promastigotes of the mutated protein LdARL-3A-Q70L, which remains constitutively associated with GTP, leads to the disappearance of the flagellum but does not impair cell viability or growth. Here we report that parasites overexpressing LdARL-3A-Q70L can invade in vitro cultivated macrophages to the same extent as control cells, demonstrating that the flagellum is not necessary for attachment to or engulfment into macrophages. These infections are productive because amastigotes differentiate and multiply. However, aflagellated LdARL-3A-Q70L-overexpressing Leishmania promastigotes could not survive in experimentally infected Lutzomyia longipalpis insect vectors, in contrast to untransfected or native LdARL-3A-overexpressing cells. Overexpression of the native and mutated proteins did not modify in vitro procyclic to metacyclic lipophosphoglycan maturation or differentiation from procyclic to metacyclic promastigotes, nevertheless there is a block in transmission of Leishmania. Better understanding of LdARL-3A pathways, notably those regarding flagellum biogenesis, may lead to the future development of Leishmania-specific drugs, which may stop parasite transmission in nature without affecting other species.

    Results are presented of a literature review to identify social and psychological aspects of abortion. The literature does not provide a true profile of women requesting abortions, but some characteristics emerge. Reasons for requesting abortion include economic problems, difficult previous pregnancies, general medical contraindications to pregnancy, marital conflicts, feelings of loneliness, professional aspirations, problems with existing children, and feelings of insecurity about the future. However, the same feelings are found among women carrying their pregnancies to term. Unplanned pregnancies are more common during periods of depression. Most authors have found about 1/2 of women seeking abortions to be single and about 1/2 to be under 25 years old. Religion does not appear to be a determining factor. 1 study of psychological factors in abortion seekers found that a large number of single women seeking abortion had suffered traumatic experiences in childhood and were seeking security in inappropriate amorous relationships. Helene Deutsch stressed the destructive impulses latent in all pregnancies. Others have cited the ambivalence of the desire for pregnancy and feelings of loss after abortion. Studies published after legalization of abortion in the US and France however have stressed the nearly total absence of moderate or severe psychiatric symptoms after abortion. Responses immediately after the abortion may include feelings of relief, guilt, indifference, or ambivalence. Secondary affects appear minor to most authors. Psychological effects do not appear to be influenced by age, marital status, parity, intelligence, occupation, existence of a later pregnancy, or concommitant sterilization. "Premorbidity" and coercion by spouse or family were most closely associated with psychological symptoms. Numerous authors have found about twice as many negative reactions among women undergoing abortion for medical reasons. Most patients undergoing abortions for

    1998-01-01

    The problems associated with illegal abortion dominate public discussion in Ireland. 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. PMID:12321445

    Listeria monocytogenes has a well-characterized ability to cross the placental barrier, resulting in spontaneous abortion and fetal infections. However, the mechanisms resulting in infection-associated abortion are not fully understood. In this study, we demonstrate that the dephosphorylation of MAPK family proteins caused by L. monocytogenes infection of trophoblast giant (TG) cells, which are placental immune cells, contributes to infectious abortion. Dephosphorylation of c-Jun, p38, and ERK1/2 was observed in infected TG cells, causing the downregulation of cytoprotective heme oxygenase (HO)-1. Blocking the dephosphorylation of proteins, including MAPK family proteins, inhibited the decrease in HO-1 expression. Treatment with MAPK inhibitors inhibited bacterial internalization into TG cells. Moreover, Toll-like receptor 2 involved in the expression of MAPK family proteins. Infection with a listeriolysin O-deleted mutant impaired dephosphorylation of MAPK family proteins in TG cells and did not induce infectious abortion in a mouse model. These results suggest that inactivation of the MAPK pathway by L. monocytogenes induces TG cell death and causes infectious abortion. PMID:26528279

    Abstract Objective To determine what proportion of women seeking induced abortion in the Calgary census metropolitan area were immigrants. Design For 2 months, eligible women were asked to complete a questionnaire. Women who refused were asked to provide their country of birth (COB) to assess for selection bias. Setting Two abortion clinics in Calgary, Alta. Participants Women presenting at or less than 15 weeks’ gestational age for induced abortion for maternal indications. Main outcome measures The primary outcome was the proportion of women seeking induced abortion services who were immigrants. Secondary outcomes compared socioeconomic characteristics and contraception use between immigrant and Canadian-born women. Results A total of 752 women either completed a questionnaire (78.6%) or provided their COB (21.4%). Overall, 28.9% of women living in the Calgary census metropolitan area who completed the questionnaire were immigrants, less than the 31.2% background proportion of immigrant women of childbearing age. However, 46.0% of women who provided only COB were immigrants. When these data were combined, 34.2% of women presenting for induced abortion identified as immigrant, a proportion not significantly different from the background proportion (P = .127). Immigrant women presenting for induced abortion tended to be older, more educated, married with children, and have increased parity. They were similar to Canadian-born women in number of previous abortions, income status, and employment status. Conclusion This study suggests that immigrant women in Calgary are not presenting for induced abortion in disproportionately higher numbers, which differs from existing European literature. This is likely owing to differing socioeconomic characteristics among the immigrant women in our study from what have been previously described in the literature (typically lower socioeconomic status). Much still needs to be explored with regard to factors influencing the use of

    1995-07-15

    The German Bundestag has passed a compromise abortion law that makes an abortion performed within the first three months of pregnancy an unlawful but unpunishable act if the woman has sought independent counseling first. Article 218 of the German penal code, which was established in 1871 under Otto von Bismarck, had allowed abortions for certain medical or ethical reasons. After the end of the first world war, the Social Democrats tried to legalize all abortions performed in the first three months of pregnancy, but failed. In 1974, abortion on demand during the first 12 weeks was declared legal and unpunishable under the social liberal coalition government of chancellor Willy Brandt; however, the same year, the German Federal Constitution Court in Karlsruhe ruled the bill was incompatible with article 2 of the constitution, which guarantees the right to life and freedom from bodily harm to everyone, including the unborn. The highest German court also ruled that a pregnant woman had to seek a second opinion from an independent doctor before undergoing an abortion. A new, extended article 218, which included a clause giving social indications, was passed by the Bundestag. When Germany was unified, East Germans agreed to be governed by all West German laws, except article 218. The Bundestag was given 2 years to revise the article; however, in 1993, the Federal Constitution Court rejected a version legalizing abortion in the first 3 months of the pregnancy if the woman sought counsel from an independent physician, and suggested the recent compromise passed by the Bundestag, the lower house of the German parliament. The upper house, the Bundesrat, where the Social Democrats are in the majority, still has to pass it. Under the bill passed by the Bundestag, national health insurance will pay for an abortion if the monthly income of the woman seeking the abortion falls under a certain limit. PMID:7613423

    This study used data from a community-based survey to examine women's experiences of abortion in Nigeria. Fourteen percent of respondents reported that they had ever tried to terminate a pregnancy, and 10% had obtained an abortion. The majority of women who sought an abortion did so early in the pregnancy. Forty-two percent of women who obtained an abortion used the services of a non-professional provider, a quarter experienced complications and 9% sought treatment for complications from their abortions. Roughly half of the women who obtained an abortion used a method other than D&C or MVA. The abortion prevalence and conditions under which women sought abortions varied by women's socio-demographic characteristics. Because abortion is illegal in Nigeria except to save the woman's life, many women take significant risks to terminate unwanted pregnancies. Reducing the incidence of unwanted pregnancy and unsafe abortion can significantly impact the reproductive health of women in Nigeria. PMID:17711597

    Congenital anomalies contribute a significant proportion of infant morbidity and mortality, as well as fetal mortality. They are generally grouped into three major categories: structural/metabolic, congenital infections, and other conditions. The most prevalent conditions include congenital heart defects, orofacial clefts, Down syndrome, and neural tube defects. Several prenatal diagnostic procedures have been introduced, both cytogenetic (such as chorion biopsy, amniocentesis and funiculocentesis) and biophysical (ultrasound 2-D, 3-D and 4-D, ultrasonography with Doppler, etc.). Insufficient data are currently available from Saudi Arabia on the epidemiology of the lethal congenital abnormalities which should be a priority due to high rate of consanguineous marriages among first cousins and their association with congenital anomalies. In terms of consanguinity and birth defects, a significant positive association has been consistently demonstrated between consanguinity and morbidity, and congenital defects with a complex etiology appear to be both more prevalent in consanguineous families and have a greater likelihood of recurrence. A debate regarding aborting a malformed fetus still exists among the senior Islamic scholars in many of the Islamic countries. The progressive interpretations of Islam have resulted in laws allowing for early abortion on request in two countries; six others permit abortion on health grounds and three more also allow abortion in cases of rape or fetal impairment. In Saudi Arabia, efforts to legalize abortion in certain circumstances have been recently discussed among Senior Religious Scholars and specialized physicians to permit abortions in certain circumstances. In this mini-review we discuss the current debate regarding aborting a malformed fetus in Saudi Arabia with a focus on the Islamic perspective. PMID:24027674

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

    The aim of this study was to evaluate the systemic production of nitric oxide (NO) in missed and threatened abortion and in nonpregnant and regular pregnant controls with the purpose of defining its role in the mechanisms regulating the first-trimester pregnancy toward either positive or negative evolution. Patients with missed abortion showed serum NO levels clearly decreased compared with nonpregnant patients and patients with regular pregnancy and threatened abortion, supporting a direct functional role of the NO mediator in early embryonic development and confirming its importance in the uterus and cervix during abortion.

    Doctors for a Woman's Choice on Abortion would agree with 1 point in Lord Denning's ruling on the role of nurses in abortions induced by (PGS) prostaglandins (November 15, p. 1091). The nurse should not be doing a doctor's job, as Lord Denning indicated, and we sympathize with any nurse who is doing so (though the 1967 Abortion Act allows any nurse to abstain, on grounds of conscience). However, the ruling that nurses are not legally covered to participate in any way with the "procuring of a miscarriage" (using terminology of the 1861 Offenses against the Persons Act upon which the ruling is based) does not require a radical change in the practice of late abortions (constituting only 7% of the terminations) or any change in the law. PG abortion can be done without a nurse. With the extraamniotic technique, a very cheap pump can be used to give subsequent doses of the PG (a function normally performed by a nurse) through the catheter left inserted through the cervix after the 1st dose has been given by the doctor. Alternatively, the intraamniotic method can be used, where PG is instilled into the amniotic sac via a needle passed through the abdominal wall. This normally requires only 1 dose, given by the doctor. Rarely are subsequent doses needed; however they could be given by the doctor with very little addition to his or her workload. While the fact that PG abortion can be done without nurses is not realized, late abortion will be restricted, a situation which is entirely deplorable. Also deplorable are the comments of an antiabortion nature made by Lord Denning, over and above the legal ruling in his jurisdiction to make. His ruling, furthermore, seems to have been sufficiently confused for the Department of Health to withdraw its circular on abortion and await an interpretation before issuing another. PMID:6107800

    A Paris court last week challenged a 1993 law that makes it a criminal offense to obstruct abortions. The court acquitted nine anti-abortion protestors who had broken into the maternity ward of the public hospital Pitie-Salpetriere last November and prayed at the entrance of a ward where patients are admitted for abortions. The judges ruled that the protestors had not interfered with abortions being carried out because none were taking place at the time of the demonstration; furthermore, the judges stated, because the fetus could be considered a person (child), the protestors were protected by other laws which give immunity to those breaking a law in order to protect another person's life, or to defend a child that had been abandoned. The court continued to say that a fetus should be protected, whether or not it was considered a person, because it was definitely more than nothing. The Syndicat de la Magistrature, the association of French magistrates, believes the tribunal has denied the right to abortion guaranteed in the 1975 law. Veronique Neietz, who drafted the 1993 law, was "scandalized" by the decision and believes the decision of the court was made in retribution for a recent parliamentary decision to exclude anti-abortion protestors from the general amnesty given after presidential elections to minor offenders. During the same week of this court decision, two tribunals, in Lyons and in Bourg-en-Bresse, sentenced 45 anti-abortionists to suspended prison terms with fines. PMID:7613424

    Infection with the nontyphoidal Salmonella is a common cause of food-borne disease that leads to acute gastroenteritis/diarrhea. Severe/prolonged cases of Salmonella infection could also impact host nutritional status, but little is known about its effect on intestinal absorption of vitamins, including biotin. We examined the effect of Salmonella enterica serovar Typhimurium (S. typhimurium) infection on intestinal biotin uptake using in vivo (streptomycin-pretreated mice) and in vitro [mouse (YAMC) and human (NCM460) colonic epithelial cells, and human intestinal epithelial Caco-2 cells] models. The results showed that infecting mice with wild-type S. typhimurium, but not with its nonpathogenic isogenic invA spiB mutant, leads to a significant inhibition in jejunal/colonic biotin uptake and in level of expression of the biotin transporter, sodium-dependent multivitamin transporter. In contrast, infecting YAMC, NCM460, and Caco-2 cells with S. typhimurium did not affect biotin uptake. These findings suggest that the effect of S. typhimurium infection is indirect and is likely mediated by proinflammatory cytokines, the levels of which were markedly induced in the intestine of S. typhimurium-infected mice. Consistent with this hypothesis, exposure of NCM460 cells to the proinflammatory cytokines TNF-α and IFN-γ led to a significant inhibition of biotin uptake, sodium-dependent multivitamin transporter expression, and activity of the SLC5A6 promoter. The latter effects appear to be mediated, at least in part, via the NF-κB signaling pathway. These results demonstrate that S. typhimurium infection inhibits intestinal biotin uptake, and that the inhibition is mediated via the action of proinflammatory cytokines. PMID:25999427

    Worldwide, more than a billion people are infected with helminths. These worm infections generally do not lead to mortality, however, they are chronic in nature and can lead to considerable morbidity. Immunologically these infections are interesting; chronic helminth infections are characterized by skewing towards a T helper 2 type response as well as regulatory responses. The regulatory network is associated with chronic helminth infections and is thought to prevent strong immune responses against parasitic worms, allowing their long-term survival and restricting pathology. This regulatory network is thought to also temper responses to non-helminth antigens, like allergens or self-antigens, possibly leading to lower prevalence of allergies and autoimmune diseases in subjects that are chronically infected with helminths. This raises the interesting idea that helminths may bear molecules that have potential therapeutic action against allergies and possibly other inflammatory diseases. However, on the other side of the coin, this would predict that helminth infected subjects might not respond strongly to third party antigens like vaccines. This is an important issue, since most vaccines that are being developed against diseases such as HIV, tuberculosis or malaria will be introduced in areas where helminth infections are highly prevalent. Moreover, these vaccines are proving difficult to develop and are often weak, thus any confounder that would affect their efficacy needs to be taken into consideration. Helminth derived molecules have been identified that induce T helper 2 and regulatory responses via modulation of dendritic cells and some appear to do so via Toll like receptor (TLR) signaling. New insights into these pathways could be useful to antagonize suppression and hence boost vaccine efficacy or to optimize suppression induced by helminth derived molecules and control inflammatory diseases.

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

  19. Abortion restrictions may undermine welfare reform.

    PubMed

    1999-02-01

    Results from a study conducted by Pennsylvania State University's Population Research Institute indicate that more restrictive abortion laws in the US may have led to an increase in the number of single mothers, even given new welfare reform laws which make unmarried childbearing more costly. Study findings are based upon county rates of female-headed families from the 1980 and 1990 censuses, excluding those in Alaska and Hawaii. By making unmarried childbearing more costly, welfare reform has sparked a demand for abortion, while at the same time abortion laws have restricted access to abortion. An increasing number of unmarried women on welfare have therefore chosen childbearing over abortion. The study found a decline in the number of abortions in counties where abortion laws had become more strict. That states can now require abortion providers to notify the parents of minors who have abortions, to restrict Medicaid funding for abortions, and to establish 24-hour waiting periods has made abortion either a difficult or impossible option for some women. These restrictive abortion laws and geographic barriers to abortion have discouraged women from undergoing the procedure, increasing the number of female-headed families and single mothers. The public policy goal of reducing unmarried childbearing and female-headed families is being undermined by the growing geographic and legal barriers designed to discourage abortion. PMID:12348920

    This study aims to describe factors associated with the number of past abortions obtained by New York City (NYC) abortion patients in 2010. We calculated rates of first and repeat abortion by age, race/ethnicity, and neighborhood-level poverty and the mean number of self-reported past abortions by age, race/ethnicity, neighborhood-level poverty, number of living children, education, payment method, marital status, and nativity. We used negative binomial regression to predict number of past abortions by patient characteristics. Of the 76,614 abortions reported for NYC residents in 2010, 57% were repeat abortions. Repeat abortions comprised >50% of total abortions among the majority of sociodemographic groups we examined. Overall, mean number of past abortions was 1.3. Mean number of past abortions was higher for women aged 30-34 years (1.77), women with ≥5 children (2.50), and black non-Hispanic women (1.52). After multivariable regression, age, race/ethnicity, and number of children were the strongest predictors of number of past abortions. This analysis demonstrates that, although socioeconomic disparities exist, all abortion patients are at high risk for repeat unintended pregnancy and abortion. PMID:25779755

  1. [Readers' position against induced abortion].

    PubMed

    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. PMID:6913282

  2. House subcmte. tightens abortion language.

    1978-05-10

    Medicaid would help pay for abortion in fewer circumstances under the fiscal 1979 Department of Health, Education, and Welfare (HEW), appropriations bill approved May 4, 1978, by the House HEW Appropriations Subcommittee than it did in 1978. The new language would permit the funding only if the mother's life would be endangered if the pregnancy were carried to term. Current law permits abortion payments for this reason; if pregnancy results from rape or incest, or if the birth would cause the mother severe and long-lasting physical damage. Behind the scenes pressure probably will be applied to resolve the issue quickly this year since all House members are up for reelection and do not want to have such a sensitive issue intruding on their campaigns. 1 strategy being discussed is the inclusion of riders that would directly or indirectly provide federal funds for abortions in other appropriation measures such as funding for the Defense Department and federal employees health benefits. The House will have to contend with Senator Brooke (R-Massachusetts) ranking minority member on the Senate HEW Appropriations Subcommittee, who is determined to stand firm in favor of liberal abortion funding. With only minimal opposition for his Senate seat this year, Senate staffers say Brooke is not concerned with the possibility of abortion becoming a major campaign issue. It was Brooke who forced the House's hand last year and obtained a more relaxed abortion curb, much to the chagrin of the Carter Administration. The White House, with the President's popularity at a low ebb, would prefer not to be put in a position of taking sides publicly although it prefers the strict curbs. Carter is currently deciding which House members to assist during the campaign and such a no-win issue would only serve to complicate matters. He will have enough of a problem reconciling health spending increases without the added burden of abortion. PMID:12335662

    Background In Papua New Guinea abortion is restricted under the Criminal Code Act. While safe abortions should available in certain situations, frequently they are not available to the majority of women. Sepsis from unsafe abortion is a leading cause of maternal mortality. Our findings form part of a wider, mixed methods study designed to identify complications requiring hospital treatment for post abortion care and to explore the circumstances surrounding unsafe abortion. Methods Through a six month prospective study we identified all women presenting to the Eastern Highlands Provincial Hospital following spontaneous and induced abortions. We undertook semi-structured interviews with women and reviewed individual case notes, extracting demographic and clinical information. Findings Case notes were reviewed for 56% (67/119) of women presenting for post abortion care. At least 24% (28/119) of these admissions were due to induced abortion. Women presenting following induced abortions were significantly more likely to be younger, single, in education at the time of the abortion and report that the baby was unplanned and unwanted, compared to those reporting spontaneous abortion. Obtained illegally, misoprostol was the method most frequently used to end the pregnancy. Physical and mechanical means and traditional herbs were also widely reported. Conclusion In a country with a low contraceptive prevalence rate and high unmet need for family planning, all reproductive age women need access to contraceptive information and services to avoid, postpone or space pregnancies. In the absence of this, women are resorting to unsafe means to end an unwanted pregnancy, putting their lives at risk and putting an increased strain on an already struggling health system. Women in this setting need access to safe, effective means of abortion. PMID:25329982

    OBJECTIVES: The authors examined factors predicting abortion use in two communes in northern Vietnam. METHODS: A survey of 504 rural and 523 urban women of childbearing age was conducted. RESULTS: For the 13.6% of urban and 19% of rural commune women having had an abortion in the previous year, logistic regression analyses demonstrated that use of an intrauterine device reduced the likelihood of subsequent abortion in both communes. Traditional method use in the rural commune, however, increased women's likelihood of a subsequent abortion. CONCLUSIONS: Contraceptive use in these 2 communes affected abortion more than sociodemographic factors. Traditional method use by rural women is a risk for abortion. PMID:9551014

    Although constitutionally illegal, induced abortion is a vital reproductive health option in Uganda. This paper analyses men's narratives about meanings of, and experiences with, abortion. Men play significant roles in abortion as instigators, facilitators, collaborators, transporters, advisors, informers, supporters or punishment givers. Many participants were knowledgeable about abortion. Attitudes were ambivalent, with initial reactions of denial and relegation of abortion to women's private domains. Further exploration, however, revealed active support and involvement of men. Interpretations of abortion ranged from 'dependable saviour' to 'deceptive sin'. Though a private action, abortion is socially scripted and often collectively determined by wider social networks of kinsmen, the community, peers, law and religion. A disjuncture exists between dominant public health discourse and the reality of local men who interact with women and girls as wives, lovers, sex sellers, mothers, daughters and sisters. Interventions targeting men about abortion should include safe sex education, provide safe abortion services and create stronger social support mechanisms. Policy and law should incorporate local knowledge and practice. PMID:16104664

    We aimed to compare the diagnostic value of various detection methods for cytomegalovirus (CMV) infection, to investigate the genetic mechanism associated with CMV infection in pregnant women, and to analyze the risk of sequelae development in fetuses with CMV infection. A total of 300 participants who had the same immunosuppressive regimen and received preemptive therapy for CMV infection were prospectively enrolled in this study; they included 289 vaccine trial participants. The gB-absorbed CMV IgG assay was performed for each vaccine trial participant. The healthy women were divided into 2 groups, and amniotic fluids were collected from them at 15-18 weeks of gestation to test for CMV seropositivity before conception by using IgM specific antibodies, CMV-DNA, and IgG analysis. In 104 cases, cord blood sera and urine specimens were also collected from the infants and examined. The sensitivity and specificity of immediate-early messenger RNA and pp67 (late) messenger RNA detection by the nucleic acid sequence-based amplification technique was comparable to those of virus isolation and PCR. Furthermore, an association between single nucleotide polymorphisms in the TLR-2 gene and congenital CMV infection was observed and confirmed. Moreover, CMV infection during early pregnancy has been shown to have a much more severe effect on the pregnancy outcome compared to infection during later stages of pregnancy. PMID:26535638

    A sandwich enzyme-linked immunosorbent assay (ELISA) for the sensitive and specific detection of bovine antibodies to Neospora caninum was developed and evaluated using sera from cattle experimentally infected with N. caninum, Toxoplasma gondii, Sarcocystis cruzi, Sarcocystis hominis, Sarcocystis hirsuta, Eimeria bovis, Cryptosporidium parvum, Babesia divergens, and field sera from naturally exposed animals. Field sera were classified using a gold standard that included the results from an indirect fluorescent antibody test (IFAT) and an immunoblot (IB). Based on these gold standard results, i.e., IFAT-IB results, an equal relative sensitivity and specificity of 94.2%(theta0) was reached when a cutoff of 0.034 (d0) was employed. The analysis of IFAT-IB-positive field sera showed that within groups of aborting and nonaborting dams, the animals from herds with endemic N. caninum-associated abortions had significantly higher ELISA indices than animals from herds with N. caninum-associated epidemic abortions. By contrast, IFAT-IB-positive aborting dams from herds with endemic N. caninum-associated abortions had significantly lower IFAT titers than IFAT-IB-positive aborting dams from herds with epidemic N. caninum-associated abortions. This is the first time that statistically significant serological differences between herds exhibiting epidemic and endemic N. caninum-associated abortions are described. PMID:10461950

    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. PMID:12348324

    As new influenza virus strains emerge, finding new mechanisms to control infection is imperative. In this study, we found that we could control influenza infection of mammalian cells by altering the level of glucose given to cells. Higher glucose concentrations induced a dose-specific increase in influenza infection. Linking influenza virus infection with glycolysis, we found that viral replication was significantly reduced after cells were treated with glycolytic inhibitors. Addition of extracellular ATP after glycolytic inhibition restored influenza infection. We also determined that higher levels of glucose promoted the assembly of the vacuolar-type ATPase within cells, and increased vacuolar-type ATPase proton-transport activity. The increase of viral infection via high glucose levels could be reversed by inhibition of the proton pump, linking glucose metabolism, vacuolar-type ATPase activity, and influenza viral infection. Taken together, we propose that altering glucose metabolism may be a potential new approach to inhibit influenza viral infection. - Highlights: • Increased glucose levels increase Influenza A viral infection of MDCK cells. • Inhibition of the glycolytic enzyme hexokinase inhibited Influenza A viral infection. • Inhibition of hexokinase induced disassembly the V-ATPase. • Disassembly of the V-ATPase and Influenza A infection was bypassed with ATP. • The state of V-ATPase assembly correlated with Influenza A infection of cells.

    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).

    In 40 mid-trimester abortion seekers, in whom abortion was induced by extra-amniotic normal saline or Emcredil, microbiological studies were carried out before induction and at 24 hours. It was observed that there was no difference in the isolation of organisms from vagina and cervix of these subjects between 0 hours and 24 hours. Thus, this study shows that leaving the catheter in the extra-amniotic space until it is expelled spontaneously does not increase the risk of ascending infection. At the same time, leaving the catheter in-situ until it is expelled spontaneously reduces the induction-abortion interval appreciably. PMID:1486776

    The Supreme Court decision of January 22, 1973, legalizing abortion now requires school counselors to examine both their personal and professional positions on abortion information and abortion counseling. To date a review of school counseling literature reveals a failure to deal with abortion as a counseling issue. Also, schools have failed to develop official policies regarding abortion counseling and the distribution of abortion information. The counselors who have provided abortion information to date have done so at the request of a student or parent rather than by making the information generally available. A study in 1973 in Virginia, however, revealed that Virginia counselor educators believed that there was a need for counselors in training to be exposed to abortion information as part of their formal training experience. Generally, today's present exposure to abortion information makes it impossible for counselors to continue to ignore a growing demand for both abortion information and counseling. School counselors must deal with the following questions: 1) What course of action should school counselors take when a pregnant young seeks counseling on alternatives to pregnancy continuation? 2) What is the counselor's professional role in abortion counseling with respect to his or her personal feelings and beliefs? 3) What kind of training if any should school counselors receive regarding abortion counseling? 4) Is there a need for in-service training on abortion counseling for school counselors? 5) Should various professional organizations develop materials that would assist their members in providing abortion counseling? 6) Should institutions such as schools, churches, and community agencies establish policies concerning abortion counseling? Although the answers are not simple, the school counselors and their professional organizations must begin to develop the answers in order to provide good counseling services to young women exercising their right to

    A prospective study of the maternal mortality and morbidity and other related social problems among 144 cases of procured abortion in Ilorin, Nigeria over a 24-month period is presented. A mortality rate of 90.3 per thousand procured abortions was recorded. Genital sepsis, haemorrhagic anaemia, gut injury, uterine perforation and vesico vaginal fistulae (VVF) were encountered. Poor referral system, late presentation, poor blood transfusion services and inadequate availability of drugs had adverse effects on the patients. The implications (the menace and frequency) of these and possible measures like improving the literacy level, the moral standards, contraceptive practice and family life education (sex education) are discussed.

    SUMMARY The aim of this review is to present the current state of knowledge on human latent tuberculosis infection (LTBI) based on clinical studies and observations, as well as experimental in vitro and animal models. Several key terms are defined, including “latency,” “persistence,” “dormancy,” and “antibiotic tolerance.” Dogmas prevalent in the field are critically examined based on available clinical and experimental data, including the long-held beliefs that infection is either latent or active, that LTBI represents a small population of nonreplicating, “dormant” bacilli, and that caseous granulomas are the haven for LTBI. The role of host factors, such as CD4+ and CD8+ T cells, T regulatory cells, tumor necrosis factor alpha (TNF-α), and gamma interferon (IFN-γ), in controlling TB infection is discussed. We also highlight microbial regulatory and metabolic pathways implicated in bacillary growth restriction and antibiotic tolerance under various physiologically relevant conditions. Finally, we pose several clinically important questions, which remain unanswered and will serve to stimulate future research on LTBI. PMID:25184558

    In India, safe abortion services are sought mainly in the private sector for reasons of privacy, confidentiality, and the absence of delays and coercion to use contraception. In recent years, the declining sex ratio has received much attention, and implementation of the Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act (2003) has become stringent. However, rather than targeting sex determination, many inspection visits target abortion services. This has led to many private medical practitioners facing negative media publicity, defamation and criminal charges. As a result, they have started turning women away not only in the second trimester but also in the first. Samyak, a Pune-based, non-governmental organization, came across a number of cases of refusal of abortion services during its work and decided to explore the experiences of private medical practitioners with the regulatory mechanisms and what happened to the women. The study showed that as a fallout from the manner of implementation of the PCPNDT Act, safe abortion services were either difficult for women to access or outright denied to them. There is an urgent need to recognize this impact of the current regulatory environment, which is forcing women towards illegal and unsafe abortions. PMID:26278839

    Pseudomonas aeruginosa is a remarkably versatile environmental bacterium with an extraordinary capacity to infect the cystic fibrosis (CF) lung. Infection with P. aeruginosa occurs early, and although eradication can be achieved following early detection, chronic infection occurs in over 60% of adults with CF. Chronic infection is associated with accelerated disease progression and increased mortality. Extensive research has revealed complex mechanisms by which P. aeruginosa adapts to and persists within the CF airway. Yet knowledge gaps remain, and prevention and treatment strategies are limited by the lack of sensitive detection methods and by a narrow armoury of antibiotics. Further developments in this field are urgently needed in order to improve morbidity and mortality in people with CF. Here, we summarize current knowledge of pathophysiological mechanisms underlying P. aeruginosa infection in CF. Established treatments are discussed, and an overview is offered of novel detection methods and therapeutic strategies in development. PMID:27175979

    The genus Candida includes about 200 different species, but only a few species are human opportunistic pathogens and cause infections when the host becomes debilitated or immunocompromised. Candida infections can be superficial or invasive. Superficial infections often affect the skin or mucous membranes and can be treated successfully with topical antifungal drugs. However, invasive fungal infections are often life-threatening, probably due to inefficient diagnostic methods and inappropriate initial antifungal therapies. Here, we briefly review our current knowledge of pathogenic species of the genus Candida and yeast infection causes and then focus on current antifungal drugs and resistance mechanisms. An overview of new therapeutic alternatives for the treatment of Candida infections is also provided. PMID:23878798

    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.

    OBJECTIVE—To analyse the long term results of mechanical prostheses for treating active infective endocarditis.
DESIGN—Prospective cohort study of a consecutive series of patients diagnosed with infective endocarditis and operated on in the active phase of the infection for insertion of a mechanical prosthesis.
SETTING—Tertiary referral centre in a metropolitan area.
RESULTS—Between 1975 and 1997, 637 cases of infective endocarditis were diagnosed in the centre. Of these, 436 were left sided (with overall mortality of 20.3%). Surgical treatment in the active phase of the infection was needed in 141 patients (72% native, 28% prosthetic infective endocarditis). Mechanical prostheses were used in 131 patients. Operative mortality was 30.5% (40 patients). Ninety one survivors were followed up prospectively for (mean (SD)) 5.4 (4.5) years. Thirteen patients developed prosthetic valve dysfunction. Nine patients suffered reinfection: four of these (4%) were early and five were late. The median time from surgery for late reinfection was 1.4 years. During follow up, 12 patients died. Excluding operative mortality, actuarial survival was 86.6% at five years and 83.7% at 10 years; actuarial survival free from death, reoperation, and reinfection was 73.1% at five years and 59.8% at 10 years.
CONCLUSIONS—In patients surviving acute infective endocarditis and receiving mechanical prostheses, the rate of early reinfection compares well with reported results of homografts. In addition, prosthesis dysfunction rate is low and long term survival is good. These data should prove useful for comparison with long term studies, when available, using other types of valve surgery in active infective endocarditis.

    PubMed

    Isambert, F A

    1982-01-01

    Abortion is a thorny problem whose study is problematic because it is a source of social and juridical discord, of moral incertitude, of medical and psychiatric confusion, and of personal anguish. The question arises of whether a single perspective can be found which allows comprehension of the entire phenomenon. This work uses published sources to examine the abortion debate, beginning with the varying views of abortion expressed in the struggles to liberalize abortion legislation in France, Europe, and the US. 4 particular views of abortion were identified in the Paris press; the traditional religious view, which condemns abortion because the fetus is regarded as fully human from conception; the view of abortion as a means of fertility regulation; the view of abortion as a cause of public health problems that could be alleviated through legalization and medical control; and the view that abortion allows women to control their own bodies. The law is obliged to reconcile these diverse positions. Abortion legislation in different countries ranges along a continuum from severe to lenient, but regional variations are also evident. Abortion trials in the US and France shortly before liberalization of the laws of either country showed striking similarities but also notable differences due largely to dissimilarities in the social structures of the 2 countries. The relations between the individual and the state, morality, and the law, as reflected in the abortion debate, rested on inverse bases in the 2 countries. The typically American doctrine of privacy occupied a prominent place in the American legislation, while the French was more concerned with the humanitarian goal of reducing health damage from illegal abortions. Tension and ambiguity nevertheless unavoidably characterize the abortion regulations in the 2 countries. Abortion as an institution is a controlled and practical compromise between 2 poles, those giving primacy to individual interests, as in the US, and

    1991-05-23

    A report sent by the Vatican to bishops' conferences throughout the world calls RU-486, the so-called abortion pill currently available in France, "a new, serious threat to human life." The report was developed at the Vatican's request by Gonzalo Herranz, a Spanish bioethicist. A cover letter to bishops' conferences from Cardinal Alfonso Lopez Trujillo, president of the Pontifical Council for the Family, suggested that the report be used "to resist the introduction of the abortion pill RU-486 into your country." Related to TU-486 and to new terminology some use to characterize its non-surgical approach to abortion is an intention "to amoralize and thereby place the transmission of human life into an ethically neutral terrain and reduce it to pure biology," says the report. The report discusses possible future uses of RU-486 as a contraceptive, stating: "Women would no longer have to worry themselves about whether they have conceived or not. Each month they would proceed to clean out their uterus chemically." The report refers to RU-486 as "a technical step forward in an area that did not need it." It says, "The abortion pill favors a woman's privacy and secret, but it condemns her to solitude." The English text from the Vatican follows. PMID:16145821

    Pornography consumption may affect judgments on a wide range of sexual and reproductive topics. The present study hypothesized that the consistent images projected in pornography affect sexual scripts related to abortion judgments. National, three-wave longitudinal data gathered from U.S. adults were employed to examine associations between earlier pornography consumption and subsequent support for abortion. The findings suggested that prior pornography consumption may lead to later support for abortion. This study provides additional evidence of pornography's socializing impact, particularly for the older White segment of the population, and adds to knowledge about what environmental factors influence judgments about abortion. Mechanisms that may explain how pornography viewing shapes support for abortion are discussed. PMID:25010599

    Unintended pregnancy is common in Uganda, leading to high levels of unplanned births, unsafe abortions, and maternal injury and death. Because most pregnancies that end in abortion are unwanted, nearly all ill health and mortality resulting from unsafe abortion is preventable. This report summarizes evidence on the context and consequences of unintended pregnancy and unsafe abortion in Uganda, points out gaps in knowledge, and highlights steps that can be taken to reduce levels of unintended pregnancy and unsafe abortion, and, in turn, the high level of maternal mortality.

Half of Bolivian women experience pregnancy and childbirth without the support of trained medical staff. Mortality from abortion complications account for about half of all maternal deaths in Bolivia. Voluntary family planning workers teach women about the benefits of child spacing, breast feeding, nutrition, prenatal and postpartum care, and safe deliveries. Bolivia has succeeded in increasing its contraceptive use rates and decreasing the number of safe and unsafe abortions. Bolivia's program effort was supported by USAID. USAID provided technical assistance and funds for the establishment of a network of primary health care clinics. Mrs. Clinton visited one such clinic in a poor neighborhood in La Paz, which in its first six months of operation provided 2200 consultations, delivered 200 babies, registered 700 new family planning users, and immunized 2500 children. Clinics such as this one will be affected by the US Congress's harsh cuts in aid, which reduce funding by 35% and delay program funding by 9 months. These US government cuts in foreign aid are expected to result in an additional 1.6 million abortions, over 8000 maternal deaths, and 134,000 infant deaths in developing countries. An investment in population assistance represents a sensible, cost-effective, and long-term strategy for improving women's health, strengthening families, and reducing abortion. PMID:12293000

    The contention that abortion harms women constitutes a new strategy employed by the pro-life movement to supplement arguments about fetal rights. David C. Reardon is a prominent promoter of this strategy. Post-abortion syndrome purports to establish that abortion psychologically harms women and, indeed, can harm persons associated with women who have abortions. Thus, harms that abortion is alleged to produce are multiplied. Claims of repression are employed to complicate efforts to disprove the existence of psychological harm and causal antecedents of trauma are only selectively investigated. We argue that there is no such thing as post-abortion syndrome and that the psychological harms Reardon and others claim abortion inflicts on women can usually be ascribed to different causes. We question the evidence accumulated by Reardon and his analysis of data accumulated by others. Most importantly, we question whether the conclusions Reardon has drawn follow from the evidence he cites. PMID:19594725

    The abortion issue has infested national politics since 1973, now it returns to haunt the US presidential election politics. However, rather than serving as a customary rallying cause for Republicans, it is now a millstone around the neck of their candidate, Governor George Bush, who seeks a broad ideological span of voters to win his candidacy. Bush expressed strong anti-abortion sentiments to attract the die-hard right-to-life vote in the hard-fought primary campaign. For many years, the anti-abortion language in the US remains strident, however, it is clear that most voters support, or at least tolerate, the availability of abortion services. In his presidential campaign, Bush shied away from endorsing a constitutional amendment to ban abortion, and declared his opposition to any exceptions to an abortion ban. He is now on the record with numerous anti-abortion declarations, and holds endorsements from the pro-life camp. PMID:10791389

    This Note examines how both the law and the health care profession neglect women's needs for abortion counseling before, during and after an abortion. Part I analyzes the health care profession's view of counseling, the psychological effects of abortion and how counseling both positively and negatively influences those effects. Part II reviews Supreme Court cases and state law regarding abortion counseling, critizing both the Court's narrow view of counseling and the states' failure to use the legislative process to create laws which benefit maternal health. Part III recommends an expanded role for abortion counseling, in which the counselor can provide emotional support from before the day of an abortion until a woman emotionally recovers from an abortion. This expanded role would be state-mandated, but would remain within constitutional boundaries by providing flexibility for counselors to give individual treatment while respecting a woman's privacy.

    An historical review of the use of induced abortion is presented, beginning with early eras. The Chinese were the 1st to record the practice of induced abortion, with this operation being administered to royal concubines recorded at 500-515 B.C. Induced abortion was not used in ancient Greece, either for criminal or ethical reason. However, the ancient Greeks did utilize compulsory abortion for serious economic indications, as a means of controlling natural growth. Greek medical, gyneoclogigcal instruments for adminsitering abortions were described by Hippocrates. The Greek moral attitudes on abortion were largely adopted by the Romans, which were later altered by the appearance of Christianity and new ethical ideas. These ideas dominated European attitudes, along with the Church of Rome, limiting induced abortion to cases where the life of the mother was threatened. This attitude has existed until the present century, when these moral ideas are being challanged seriously for the 1st time in modern history. PMID:4610534

    Bovine abortion of unknown infectious etiology still remains a major economic problem. Thus, we investigated whether Brucella spp., Listeria monocytogenes, Salmonella spp., Campylobacter spp. and Coxiella burnetii are associated with abortion and/or stillbirth in Tunisian dairy cattle. Using a pan-Chlamydiales PCR, we also investigated the role of Chlamydiaceae, Waddlia chondrophila, Parachlamydia acanthamoebae and other members of the Chlamydiales order in this setting. Veterinary samples taken from mid to late-term abortions from twenty dairy herds were tested. From a total of 150 abortion cases collected, infectious agents were detected by PCR in 73 (48.66%) cases, 13 (8.66%) of which represented co-infections with two infectious agents. Detected pathogens include Brucella spp (31.3%), Chlamydiaceae (4.66%), Waddlia chondrophila (8%), Parachlamydia acanthamoebae (5.33%), Listeria monocytogenes (4.66%) and Salmonella spp. (3.33%). In contrast, Campylobacter spp. and Coxiella burnetii DNA were not detected among the investigated veterinary samples. This demonstrates that different bacterial agents may cause bovine abortion in Tunisia. This is the first report suggesting the role of Parachlamydia acanthamoebae in bovine abortion in Africa. Further studies with a larger number of samples are necessary to confirm whether this emerging pathogen is directly linked to abortion in cattle. PMID:24662769

    Abortion, primarily as a measure of population control, certainly continues to be an emotional, frustrating and stressful event. In continuation of our work on stressful situations in the female life span and biochemical parameters, serum lipid peroxide levels in terms of malondialdehyde (nmol/ml) have been determined in females undergoing abortion [suction curettage (n = 30), Emcredil-induced abortion (n = 30) and spontaneous abortion (n = 40)] and were compared with appropriate gestational controls. Irrespective of the type of abortion, the serum lipid peroxide levels before abortion [mean malondialdehyde concentrations (nmol/ml): suction curettage 2.67, Emcredil-induced abortion 3.22, and spontaneous abortion 3.49] were found to be significantly elevated in comparison with those after abortion (suction curettage 1.91, Emcredil 1.97 and spontaneous abortion 1.95), indicating a maximum at peak time of stress and a minimum at the end of stress. The levels of serum lipid peroxide encountered before abortion were found to be significantly elevated in case of Emcredil-induced abortion and spontaneous abortion when compared with controls (second trimester mean levels 1.82 and first trimester 2.4) whereas the levels before suction curettage were found to be nonsignificant in comparison with controls, indicating a lesser degree of stress. It is felt that monitoring of serum lipid peroxide levels in serum and tissues (placenta), backed by scavenging enzyme superoxide dismutase, can be more helpful for corroborating safety and the risk of free radical toxicity in pregnancy and abortion.

  18. Unsafe abortion and postabortion care - an overview.

    PubMed

    2011-07-01

    Forty per cent 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 per 1 000 women. The circumstances under which women obtain unsafe abortion vary and depend on traditional methods known and types 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 66 500 women die every year as a result of unsafe abortions. In addition, a far larger number of women experience short- and long-term health consequences. To address the harmful health consequences of unsafe abortion, a postabortion care model has been developed and implemented with success in many countries where women do not have legal access to abortion. Postabortion care focuses on treatment of incomplete abortion and provision of postabortion contraceptive services. To enhance women's access to postabortion care, focus is increasingly being placed on upgrading midlevel providers to provide emergency treatment as well as implementing misoprostol as a treatment strategy for complications after unsafe abortion.

    Fifty nonaborted and 50 aborted bovine foetuses were examined utilizing histology, immunoelectrophoresis, bacteriology and the fluorescent antibody technique. Lesions were observed in 12 of the nonaborted foesuses and in four of these immunoglobulins were demonstrated. In addition, two of the nonaborted foetuses had immunoglobulins in the absence of observed lesions. Lesions were observed in 48 of the aborted foetuses and immunoglobulins were detected in 22 of these. An etiological diagnosis was arrived at in 24 of the 50 aborted foetuses. The tissues most frequently observed to have lesions of diagnostic significance were eyelid, intestine, liver, lung and placenta. Intestinal lesions were observed in several foetuses in association with a variety of agents including infectious bovine rhinotracheitis. Foetuses diagnosed as aborting because of mycotic infection consistently displayed lesions in their eyelids. The value of taking eyelid sections in cases of suspected mycotic abortions, the significance of foetal intestinal lesions, the evaluation of abomasal aspirates and the diagnostic importance of immunoglobulin determinations in aborted foetuses are discussed.

    SUMMARY The brain is well protected against microbial invasion by cellular barriers, such as the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB). In addition, cells within the central nervous system (CNS) are capable of producing an immune response against invading pathogens. Nonetheless, a range of pathogenic microbes make their way to the CNS, and the resulting infections can cause significant morbidity and mortality. Bacteria, amoebae, fungi, and viruses are capable of CNS invasion, with the latter using axonal transport as a common route of infection. In this review, we compare the mechanisms by which bacterial pathogens reach the CNS and infect the brain. In particular, we focus on recent data regarding mechanisms of bacterial translocation from the nasal mucosa to the brain, which represents a little explored pathway of bacterial invasion but has been proposed as being particularly important in explaining how infection with Burkholderia pseudomallei can result in melioidosis encephalomyelitis.

    Nasopharyngeal tuberculosis (NPTB) is a noteworthy disease especially in its worldwide spread of the Mycobacterium infection. Although NPTB has been identified in less than one percent of TB cases, recent multiple case reports indicate an either increased awareness or incidence of this disease. The most helpful diagnostic tool is an uncomplicated nasopharyngeal biopsy. However, NPTB is usually ignored because it has varied clinical manifestations and similar presentations with other more common head and neck diseases. Furthermore, the most common presenting symptom is cervical lymphadenopathy mimicking nasopharyngeal carcinoma, a more common and serious disease. Treatment outcomes of NPTB are good in both HIV-positive or HIV-negative patients. In addition, pulmonary tuberculosis association was reported in wide range between 8.3% and 82% which should be considered in a treatment program. In conclusion, early diagnosis and management in NPTB can be achieved by (1) increased awareness of this disease, (2) improvement in knowledge regarding clinical manifestations, and (3) improvement of diagnostic techniques.

    Sera from 221 cattle were collected in 25 farms in Morocco to investigate the evidence and circulation of some of the main bovine abortive agents in the dairy cattle farming, where abortions are often reported. All sera were examined for brucellosis, 176 for neosporosis, 88 for leptospirosis, and 42 for Bovine viral diarrhoea (BVD/MD), Bovine Herpesvirus 1 (BHV-1) (Infectious bovine rhinotracheitis, IBR/IPV), and Bovine Herpesvirus 4 (BHV-4) infections (at least 1 sample per herd). Abortions were reported in 23 (10.4%) of the 221 tested cattle. Antibodies against the investigated pathogens were detected in all samples tested, with an overall seroprevalence of 33.48% for Brucella, 9.09% for Leptospira, 8.52% for Neospora, 37.71% for BVDV, 50% for BHV-1, 9.52% for BHV-4. As for Leptospira antibodies against serovars Hardjo, Pomona, and Tarassovi were identi ed. Mixed infections were common. The lack of evidence of non-infectious factors epidemiologically related to abortions suggested that the investigated agents are to be considered important risk factors in the dynamic of the abortion syndrome, even if further investigations are necessary to identify the abortion cause. Particular attention should be paid on brucellosis, considering the high seroprevalence and its zoonotic relevance. PMID:27033527

    By means of an immunofluorescence antibody test (IFAT), using in vitro cultured parasites as antigen, antibodies to Neospora species at titres > or = 1/1280 were found in 11 of 120 Scottish cattle that had recently aborted but in only one of 97 cattle from herds in which there had been no recent abortions (P < 0.01). The specificity of the antibodies was confirmed by the lack of cross reactivity between samples with high titres to Neospora and toxoplasma antigen in a direct agglutination test, and by the absence of reactivity at > or = 1/640 in the IFAT of convalescent sera from cattle infected experimentally with Toxoplasma gondii, Sarcocystis cruzi, Eimeria bovis, E alabamensis, Cryptosporidium parvum and Babesia divergens. These results demonstrate that Neospora species infection occurs commonly in aborting cattle in Britain, and that the IFAT may be a useful tool for investigating the infection. PMID:8036769

  6. Departure phase aborts for manned Mars missions

    NASA Astrophysics Data System (ADS)

    Dissel, Adam F.

    NASA goals are set on resumption of human activity on the Moon and extending manned missions to Mars. Abort options are key elements of any system designed to safeguard human lives and stated requirements stipulate the provision of an abort capability throughout the mission. The present investigation will focus on the formulation and analysis of possible abort modes during the Earth departure phase of manned Mars interplanetary transfers. Though of short duration, the departure phase encompasses a mission timeline where failures have frequently become manifest in historical manned spacecraft necessitating the inclusion of a departure phase abort capability. Investigated abort modes included aborts to atmospheric entry, and to Earth or Moon orbit. Considered interplanetary trajectory types included conjunction, opposition, and free-return trajectory classes. All abort modes were analyzed for aborts initiated at multiple points along each of these possible departure trajectories across all launch opportunities of the fifteen-year Earth-Mars inertial period. The consistently low departure velocities of the conjunction trajectories facilitated the greatest abort capability. An analysis of Mars transportation architectures was performed to determine the amount of available delta V inherent in each candidate architecture for executing departure aborts. Results indicate that a delta V of at least 4 km/s is required to achieve a continuous departure phase entry abort capability with abort flights less than three weeks duration for all transfer opportunity years. Less demanding transfer years have a corresponding increase in capability. The Earth orbit abort mode does not become widely achievable until more than 6 km/s delta V is provided; a capacity not manifest in any considered architecture. Optimization of the Moon abort mode resulted in slight departure date shifts to achieve improved lunar alignments. The Moon abort mode is only widely achievable for conjunction

    One hundred forty women whose pregnancies were terminated in the second trimester with prostaglandins because of suspected fetal disease have been prospectively followed to assess their subsequent fertility. In six instances difficulties had been experienced in conceiving the pregnancy that was terminated. Since abortion 104 women have conceived, 97% within 24 months of abortion but in five instances after some delay. Only one woman had not succeeded in conceiving a wished-for pregnancy. There were no apparent differences in abortion management between those women readily conceiving and those in whom there was some delay, although termination because of chromosomal reasons or anatomic abnormalities was less commonly followed by another pregnancy as compared with those terminated for rubella or other viral infections. Reduced fertility after a late prostaglandin-induced abortion thus appears to be very infrequent. PMID:3369497

    Studies on molecular structure and mechanisms of replication of a pathogen are important from both scientific and clinical viewpoints. The replication study allows us to identify key molecules to regulate life cycle of the pathogen and to screen rationally anti-pathogen drugs. The structural study helps understand how the key molecules work at atomic levels and to design adequately the drugs. In this article, we review important findings on structural and replication studies of human immunodeficiency virus (HIV). We also summarize the latest methods for the structural study, mainly focusing on computational simulation technology (in silico analysis). Finally, we summarize briefly standard methods to study replication of viruses. PMID:19177750

    Mars trajectory design options were examined that would accommodate a premature termination of a nominal manned opposition class mission for opportunities between 2010 and 2025. A successful abort must provide a safe return to Earth in the shortest possible time consistent with mission constraints. In this study, aborts that provided a minimum increase in the initial vehicle mass in low Earth orbit (IMLEO) were identified by locating direct transfer nominal missions and nominal missions including an outbound or inbound Venus swing-by that minimized IMLEO. The ease with which these missions could be aborted while meeting propulsion and time constraints was investigated by examining free return (unpowered) and powered aborts. Further reductions in trip time were made to some aborts by the addition or removal of an inbound Venus swing-by. The results show that, although few free return aborts met the specified constraints, 85% of each nominal mission could be aborted as a powered abort without an increase in propellant. Also, in many cases, the addition or removal of a Venus swing-by increased the number of abort opportunities or decreased the total trip time during an abort.

  10. Is Induced Abortion Really Declining in Armenia?

    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. PMID:27285426

    The worldwide trend toward liberalization of abortion laws has continued in the last four years with changes in Canada, Czechoslovakia, Greece, Hungary, Romania, the Soviet Union and Vietnam. Forty percent of the world's population now lives in countries where induced abortion is permitted on request, and 25 percent lives where it is allowed only if the woman's life is in danger. In 1987, an estimated 26 to 31 million legal abortions and 10 to 22 million clandestine abortions were performed worldwide. Legal abortion rates ranged from a high of at least 112 abortions per 1,000 women of reproductive age in the Soviet Union to a low of five per 1,000 in the Netherlands. In recent years, abortion rates have been increasing in Czechoslovakia, England and Wales, New Zealand and Sweden and declining in China, France, Iceland, Italy, Japan and the Netherlands. In most Western European and English-speaking countries, about half of abortions are obtained by young, unmarried women seeking to delay a first birth, while in Eastern Europe and the developing countries, abortion is most common among married women with two or more children. Mortality from legal abortion averages 0.6 deaths per 100,000 procedures in developed countries with data. Abortion services are increasingly being provided outside of hospitals, and for those performed in hospitals, overnight stays are becoming less common. National health insurance covers abortions needed to preserve the health of a pregnant woman in all developed countries except the United States, where Medicaid and federal insurance programs do not cover abortion unless the woman's life is in danger.

    CONTEXT Because of Nigeria’s low contraceptive prevalence, a substantial number of women have unintended pregnancies, many of which are resolved through clandestine abortion, despite the country’s restrictive abortion law. Up-to-date estimates of abortion incidence are needed. METHODS A widely used indirect methodology was used to estimate the incidence of abortion and unintended pregnancy in Nigeria in 2012. Data on provision of abortion and postabortion care were collected from a nationally representative sample of 772 health facilities, and estimates of the likelihood that women who have unsafe abortions experience complications and obtain treatment were collected from 194 health care professionals with a broad understanding of the abortion context in Nigeria. RESULTS An estimated 1.25 million induced abortions occurred in Nigeria in 2012, equivalent to a rate of 33 abortions per 1,000 women aged 15–49. The estimated unintended pregnancy rate was 59 per 1,000 women aged 15–49. Fifty-six percent of unintended pregnancies were resolved by abortion. About 212,000 women were treated for complications of unsafe abortion, representing a treatment rate of 5.6 per 1,000 women of reproductive age, and an additional 285,000 experienced serious health consequences but did not receive the treatment they needed. CONCLUSION Levels of unintended pregnancy and unsafe abortion continue to be high in Nigeria. Improvements in access to contraceptive services and in the provision of safe abortion and postabortion care services (as permitted by law) may help reduce maternal morbidity and mortality.

    1995-01-01

    On the eve of legislative elections on September 21, 1995, the Portuguese Family Planning Association published an open letter to the political parties about the situation of abortion in Portugal. This was part of the activities of the Working Group on the Voluntary Interruption of Pregnancy which has been carrying out relevant work about abortion in Portugal since 1991. This group unites diverse nongovernmental organizations (NGOs) of women, trade unions, and professionals. The open letter was approved by 19 NGOs and scores of personalities. Clandestine abortion continues to be one of the most severe health problems for women in reproductive age in Portugal and the primary cause of maternal death. The law of 6/84 on abortion, which allows for exceptions to the voluntary interruption of pregnancy for certain causes, has been considered inadequate by numerous civic and professional organizations. Only a small proportion of abortions are carried out in medical establishments out of the 16,000 abortions estimated to occur every year in Portugal. It is known that in many instances fetal malformations are diagnosed after 16 weeks of gestation, which is the limit for legal abortion stipulated in this law. Furthermore, the law has not been applied in flagrant cases, such as drug-addicted pregnant women and/or women infected with HIV. There was an attempt to revise the Penal Code with regard to this matter; however, its submission for debate to the National Assembly has been blocked. This shows that the question of illegal abortion continues to be a taboo topic for many politicians instead of a serious public health concern. The reasons why women undergo abortion are: contraceptive failure or method unreliability, and socioeconomic as well as emotional factors. The political parties are exhorted to exhibit the courage to amend the existing law and solve this problem. PMID:12179259

    156 women, 12-20 weeks pregnant, applied for abortion at the Wilhelmo Clinic in Amsterdam; 102 abortions were granted. The 156 late-abortion seekers were compared with 282 early-abortion seekers and 490 pregnant women. The late-abortion seekers were significantly younger (P .05). A significantly greater number of women over 30 applied for early abortion (P .001). Unmarried or divorced women were more likely to apply to abortion (P .001). Nulliparae applied more frequently for late abortion, compared to early-abortion seekers (P .001). Women with only one child were more likely to be in the pregnancy group (p .05), with 2 children in the early-abortion group (p .001). Women from Surinam and the Antilles were more likely to be in the early abortion group (p .001). Of the late-abortion seekers, 9 had medical indications. Many had psychosocial problems; 91 had problems with partner relations. In 24 cases the delay in seeking abortion was due to a doctor. An ambivalent attitude toward the abortion existed in 22 of the patients. 83% of the late-abortion seekers and 11.3% of the early-abortion seekers had previously had an abortion. The contraceptive use of the late-abortion seekers was not regular. 1.3% of the late-abortion seekers and 9.9% of the early-abortion seekers were using IUDs at the time of conception. PMID:1012384

    A technique of ambulatory abortion for first trimester pregnancies by vacuum suction curettage under local anesthesia with intracervical block is described. The apparatus and relevant problems are discussed. A shortened speculum devised by the author and considered an improvement for this procedure, and a simplified sterile field are described. The complication rate of 0.48% based on 5641 reported cases is very low: there were no deaths, two cases of uterine perforation, 14 of incomplete abortion, 20 of infection, 1 of depression, no cervical lacerations; 27 patients were hospitalized. The advantages of this method are safety, simplicity, minimal blood loss and immediate recovery. It is preferable to the usual dilatation and curettage, does not require general anesthesia and can be used in small clinics or in hospitals on an ambulatory basis. PMID:4758593

    Smears and imprints were made from the liver of 27 equine fetuses, believed to have aborted as a result of Equine Virus Abortion (EVA) infection. Several different fixatives and staining techniques were employed for the demonstration of typical intra-nuclear inclusion bodies in these preparations, and the following conclusions were reached. Methanol proved to be the best fixative and Pappenheim's panoptic method was the best staining technique, giving good contrast and definition of the inclusion bodies. Cytological methods provided a simple and rapid means of diagnosis, but histological sections provided evidence of lesions which was most useful when inclusion bodies were very difficult to find. However, cytological methods proved better than histological sections for the demonstration of EVA intranuclear inclusion bodies. ImagesFig. 1. PMID:4192198

    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.

Although safe specialist services are available to women who can afford them, others access services under unsafe and exploitative conditions. At the time of this writing, a draft bill that will legalize abortion in instances of rape, incest, and fetal abnormalities awaits approval, amid opposition. In this article, I explore the current push for legal reform as a solution to unsafe abortion. Although a welcome effort, this amendment alone will be insufficient to address the public health consequences of unsafe abortion in Sri Lanka because most women seek abortions for other reasons.

    Self-in-relation theory and pilot data responses to an Abortion Decision Balance Sheet by 20 women attending an abortion-providing clinic challenge previous formulations of the abortion decision. Pilot data suggest that: women may make an abortion decision based primarily on pragmatics, a belief in their right to choose and knowledge of the safety and simplicity of the procedure. A discrepancy may exist for a significant minority of women between their abstract beliefs/knowledge and the personal meaning for them of the pregnancy, abortion and its safety. Important links may exist between maternal attachment and anxiety about the safety of the abortion procedure. Ramifications for counselling and future research are discussed. PMID:8528379

    The clinical and biological significance of the study of fungal pathogen Candida albicans (C. albicans) has markedly increased. However, the explicit pathogenic and invasive mechanisms of such host-pathogen interactions have not yet been fully elucidated. Therefore, the essential functional modules involved in C. albicans-zebrafish interactions were investigated in this study. Adopting a systems biology approach, the early-stage and late-stage protein-protein interaction (PPI) networks for both C. albicans and zebrafish were constructed. By comparing PPI networks at the early and late stages of the infection process, several critical functional modules were identified in both pathogenic and defensive mechanisms. Functional modules in C. albicans, like those involved in hyphal morphogenesis, ion and small molecule transport, protein secretion, and shifts in carbon utilization, were seen to play important roles in pathogen invasion and damage caused to host cells. Moreover, the functional modules in zebrafish, such as those involved in immune response, apoptosis mechanisms, ion transport, protein secretion, and hemostasis-related processes, were found to be significant as defensive mechanisms during C. albicans infection. The essential functional modules thus determined could provide insights into the molecular mechanisms of host-pathogen interactions during the infection process and thereby devise potential therapeutic strategies to treat C. albicans infection.

    Arenaviruses can cause fatal human haemorrhagic fever (HF) diseases for which vaccines and therapies are extremely limited. Both the New World (NW) and Old World (OW) groups of arenaviruses contain HF-causing pathogens. Although these two groups share many similarities, important differences with regard to pathogenicity and molecular mechanisms of virus infection exist. These closely related pathogens share many characteristics, including genome structure, viral assembly, natural host selection and the ability to interfere with innate immune signalling. However, members of the NW and OW viruses appear to use different receptors for cellular entry, as well as different mechanisms of virus internalization. General differences in disease signs and symptoms and pathological lesions in patients infected with either NW or OW arenaviruses are also noted and discussed herein. Whilst both the OW Lassa virus (LASV) and the NW Junin virus (JUNV) can cause disruption of the vascular endothelium, which is an important pathological feature of HF, the immune responses to these related pathogens seem to be quite distinct. Whereas LASV infection results in an overall generalized immune suppression, patients infected with JUNV seem to develop a cytokine storm. Additionally, the type of immune response required for recovery and clearance of the virus is different between NW and OW infections. These differences may be important to allow the viruses to evade host immune detection. Understanding these differences will aid the development of new vaccines and treatment strategies against deadly HF viral infections. PMID:24068704

    2011-01-01

    The hallmark of HIV-1 and SIV infections is CD4+ T cell depletion. Both direct cell killing and indirect mechanisms related to immune activation have been suggested to cause the depletion of T cells. We have now identified a mechanism by which immune activation-induced fibrosis of lymphoid tissues leads to depletion of naive T cells in HIV-1 infected patients and SIV-infected rhesus macaques. The T regulatory cell response to immune activation increased procollagen production and subsequent deposition as fibrils via the TGF-β1 signaling pathway and chitinase 3-like-1 activity in fibroblasts in lymphoid tissues from patients infected with HIV-1. Collagen deposition restricted T cell access to the survival factor IL-7 on the fibroblastic reticular cell (FRC) network, resulting in apoptosis and depletion of T cells, which, in turn, removed a major source of lymphotoxin-β, a survival factor for FRCs during SIV infection in rhesus macaques. The resulting loss of FRCs and the loss of IL-7 produced by FRCs may thus perpetuate a vicious cycle of depletion of T cells and the FRC network. Because this process is cumulative, early treatment and antifibrotic therapies may offer approaches to moderate T cell depletion and improve immune reconstitution during HIV-1 infection.

  8. Abortion checks at German-Dutch border.

    PubMed

    Von Baross, J

    1991-05-01

    The commentary on West German abortion law, particularly in illegal abortion in the Netherlands, finds the law restrictive and in violation of the dignity and rights of women. The Max-Planck Institute in 1990 published a study that found that a main point of prosecution between 1976 and 1986, as reported by Der Spiegal, was in border crossings from the Netherlands. It is estimated that 10,000 annually have abortions abroad, and 6,000 to 7,000 in the Netherlands. The procedure was for an official to stop a young person and query about drugs; later the woman would admit to an abortion, and be forced into a medical examination. The German Penal Code Section 218 stipulates abortion only for certain reasons testified to by a doctor other than the one performing the abortion. Counseling on available social assistance must be completed 3 days prior to the abortion. Many counseling offices are church related and opposed to abortions. Many doctors refuse legally to certify, and access to abortion is limited. The required hospital stay is 3-4 nights with no day care facilities. Penal Code Section 5 No. 9 allows prosecution for uncounseled illegal abortion. Abortion law reform is anticipated by the end of 1992 in the Bundestag due to the Treaty or the Unification of Germany. The Treaty states that the rights of the unborn child must be protected and that pregnant women relieve their distress in a way compatible with the Constitution, but improved over legal regulations from either West or East Germany, which permits abortion on request within 12 weeks of conception without counseling. It is hoped that the law will be liberalized and Penal Code Section 5 No. 9 will be abolished. PMID:12343177

    HIV-1 can disseminate between susceptible cells by two mechanisms: cell-free infection following fluid-phase diffusion of virions and by highly-efficient direct cell-to-cell transmission at immune cell contacts. The contribution of this hybrid spreading mechanism, which is also a characteristic of some important computer worm outbreaks, to HIV-1 progression in vivo remains unknown. Here we present a new mathematical model that explicitly incorporates the ability of HIV-1 to use hybrid spreading mechanisms and evaluate the consequences for HIV-1 pathogenenesis. The model captures the major phases of the HIV-1 infection course of a cohort of treatment naive patients and also accurately predicts the results of the Short Pulse Anti-Retroviral Therapy at Seroconversion (SPARTAC) trial. Using this model we find that hybrid spreading is critical to seed and establish infection, and that cell-to-cell spread and increased CD4+ T cell activation are important for HIV-1 progression. Notably, the model predicts that cell-to-cell spread becomes increasingly effective as infection progresses and thus may present a considerable treatment barrier. Deriving predictions of various treatments' influence on HIV-1 progression highlights the importance of earlier intervention and suggests that treatments effectively targeting cell-to-cell HIV-1 spread can delay progression to AIDS. This study suggests that hybrid spreading is a fundamental feature of HIV infection, and provides the mathematical framework incorporating this feature with which to evaluate future therapeutic strategies.

    1999-05-01

    Neospora caninum, a recently discovered protozoan parasite closely related to Toxoplasma gondii, has world-wide been recognized as an important cause of bovine abortion. N. caninum possesses a wide host range. The dog can be a definitive host for N. caninum. In cattle, the infection is transmitted transplacentally with high efficiency, while the majority of congenitally infected calves is clinically normal at birth and thereafter. Whether horizontal transmission occurs in cattle and whether this potential mode of transmission has epidemiological significance, remains to be elucidated. N. caninum-associated abortions can occur in epidemic or endemic form in a herd. The clinical symptoms of bovine neosporosis are confined to the occurrence of abortion, stillbirth and weak calves. Multifocal nonsuppurative encephalitis represents the most frequent pathohistological finding in N. caninum-associated abortions. The causative agent can be demonstrated by immunohistochemistry or polymerase chain reaction. Serological techniques can be used for indirect diagnosis. On the basis of the available diagnostic methods and the present knowledge about the epidemiology of the infection proposals are made regarding diagnosis, epidemiological assessment and prophylaxis of N. caninum-associated abortion problems in cattle herds.

    The impact of HIV/AIDS infection on the decision of women living with HIV/AIDS to interrupt a pregnancy remains an understudied topic. In an effort to understand the influence of HIV/AIDS diagnosis on abortion practices, a qualitative study was carried out in seven Brazilian municipalities with women living with HIV/AIDS who reported inducing an abortion at some point in their lives. This study presents the analysis of interviews with thirty women who became pregnant after diagnosis. The results show that for some women, infection was the primary motive for terminating their pregnancy, while for others, the motives for abortion were predominantly related to life circumstances. The decision to abort due to HIV infection is not the same for all women. It is related to the timing of the diagnosis and other aspects of the woman's life during her pregnancy, such as the relationship with her partner, her job and family support. The results suggest the need for more attention from health services to the reproductive decisions of women living with HIV/Aids; the incorporation of men into sexual and reproductive health prevention actions; and a deeper discussion of the illegality of abortion in Brazil and its harmful consequences for women, men, and children.

    OBJECTIVE: To determine the outcome and side effects of a new drug protocol to induce abortion. DESIGN: Case series. SETTING: An urban primary care practice. PATIENTS: One hundred consecutive patients who requested elective termination of pregnancies of less than 8 weeks' gestation. INTERVENTION: Subjects received methotrexate (50 mg/m2 body surface area, administered intramuscularly) and, 3 days afterward, misoprostol (800 micrograms, given vaginally). OUTCOME MEASURES: Number of abortions induced within 24 hours and within 10 days of misoprostol administration, number of surgical aspirations conducted because of incomplete abortion, mean amount of bleeding and pain and the number of women who, if faced with the same situation, said they would again choose a drug-induced abortion over a surgical one. RESULTS: Abortion occurred within 24 hours of misoprostol administration among 48 women and within 10 days among 69 women. In total, 89 women had an abortion without surgical aspiration. Of these women, 71 said they would choose a drug-induced abortion if faced with the choice again. CONCLUSION: Abortion induced with methotrexate and misoprostol appears to be a feasible alternative to surgical abortion and deserves further study. PMID:8548705

    Surgical abortion has been provided liberally in Australia since the early 1970s, mainly in privately owned specialist clinics. The introduction of medical abortion, however, was deliberately obstructed and consequently significantly delayed when compared to similar countries. Mifepristone was approved for commercial import only in 2012 and listed as a government subsidised medicine in 2013. Despite optimism from those who seek to improve women's access to abortion, the increased availability of medical abortion has not yet addressed the disadvantage experienced by poor and non-metropolitan women. After telling the story of medical abortion in Australia, this paper considers the context through which it has become available since 2013. It argues that the integration of medical abortion into primary health care, which would locate abortion provision in new settings and expand women's access, has been constrained by the stigma attached to abortion, overly cautious institutionalised frameworks, and the lack of public health responsibility for abortion services. The paper draws on documentary sources and oral history interviews conducted in 2013 and 2015. PMID:26719008

    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. PMID:24338232

    Fifteen to twenty percent of all pregnancies end in spontaneous abortion. For many women, this loss is nearly the equivalent of the loss of a real baby. To explore the complexity of women's responses to spontaneous abortion, nine women were given a questionnaire to complete regarding experiences and behaviors at the time of the miscarriage. The data revealed that each woman was affected, to some degree, by her experience with a spontaneous abortion. A comprehensive psychologic approach to this special client is needed to help more effectively the woman who aborts in the first trimester cope with the very real loss of an infant. PMID:3844461

    This study comprises 75 men who have been involved in legal abortion. The men answered a questionnaire concerning living conditions and attitudes about pregnancy and abortion. Most men were found to be in stable relationships with good finances. More than half clearly stated that they wanted the woman to have an abortion while 20 stressed that they submitted themselves to their partner's decision. Only one man wanted the woman to complete the pregnancy. Apart from wanting children within functioning family units, the motivation for abortion revealed that the desire to have children depended on the ability to provide qualitatively good parenting. More than half the men had discussed with their partner what to do in event of pregnancy and half had decided to have an abortion if a pregnancy occurred. More than half expressed ambivalent feelings about the coming abortion, using words such as anxiety, responsibility, guilt, relief and grief. In spite of these contradictory feelings, prevailing expectations concerning lifestyle make abortion an acceptable form of birth control. A deeper understanding of the complexity of legal abortion makes it necessary to accept the role of paradox, which the ambivalence reflects. Obviously, men must constitute a target group in efforts to prevent abortions. PMID:10528006

    In January 1988 the Supreme Court of Canada struck down the country's archaic abortion law on the ground that it imposed arbitrary delays and unfair disparities in access to abortion across the country. Since then, the conservative government of Canada has made a few attempts to introduce a new abortion policy, but it did not get passed in the parliament because the revised bills failed to protect women's right to 'life, liberty, and security of the person' within the meaning of the Canadian Charter. Canada has been without an abortion law for over four years and there has been a wide range of provincial policies and confusion in the country. Despite the legal vacuum, Canadian women are not frenziedly having abortions. However, the militancy of the anti-abortion groups has steadily intensified with continued assault on a woman's right to make reproductive choices. Since no law, short of banning abortions altogether, is going to satisfy abortion opponents, the abortion battle will rage on in Canada. PMID:8065237

    This study analyzes the involvement of men in abortion in Vietnam, where induced abortion is legal and abortion rates are among the highest in the world. Twenty men were interviewed in 1996 about the role they played in their wives' abortions and about their feelings and ethical views concerning the procedure. The results showed that both husbands and wives considered the husband to be the main decisionmaker regarding family size, which included the decision to have an abortion, but that, in fact, some women had undergone an abortion without consulting their husbands in advance. Parents and in-laws were usually not consulted; the couples thought they might object to the decision on moral grounds. Respondents' ethical perspectives on abortion are discussed. When faced with an unwanted pregnancy, the husbands adopted an ethics of care and responsibility toward family and children, although some felt that abortion was immoral. The study highlights the importance of understanding husbands' perspectives on their responsibilities and rights in reproductive decisionmaking and their ethical and other concerns related to abortion.

    This study examines the impact of various restrictive abortion laws on nonmarital childbearing since the passage of the 1996 welfare reform bill. The empirical results find that the price of an abortion, a Medicaid funding restriction, and a waiting period law are associated with a decrease in a state's nonmarital birthrate. The negative effects of restrictive abortion laws on a state's nonmarital birthrate are found to occur in various age groups. These findings are consistent with the hypothesis that restrictive abortion laws induce unmarried women to change their level of unprotected sexual activity or contraceptive behavior, thereby reducing the likelihood of an unwanted nonmarital pregnancy.

    ABSTRACT The immune system has numerous mechanisms that it can use to combat pathogens and eliminate infections. Nevertheless, studies of immune responses often focus on single pathways required for protective responses. We applied microarray analysis of RNA in order to investigate the types of immune responses produced against infection with the intestinal pathogen Giardia duodenalis. Infection with G. duodenalis is one of the most common causes of diarrheal disease in the world. While several potential antiparasitic effector mechanisms, including complement lysis, nitric oxide (NO), and α-defensin peptides, have been shown to inhibit parasite growth or kill Giardia in vitro, studies in vivo have thus far shown clear roles only for antibody and mast cell responses in parasite control. A total of 96 transcripts were identified as being upregulated or repressed more than 2-fold in the small intestine 10 days following infection. Microarray data were validated using quantitative PCR. The most abundant category of transcripts was antibody genes, while the most highly induced transcripts were all mast cell proteases. Among the other induced transcripts was matrix metalloprotease 7 (Mmp7), the protease responsible for production of mature α-defensins in mice. While infections in Mmp7-deficient mice showed only a small increase in parasite numbers, combined genetic deletion of Mmp7 and inducible nitric oxide synthase (iNOS, Nos2) or pharmacological blockade of iNOS in Mmp7-deficient mice resulted in significant increases in parasite loads following infection. Thus, α-defensins and NO are redundant mechanisms for control of Giardia infections in vivo. PMID:24194537

    Congenital Chagas disease, a neglected tropical disease, endemic in Latin America, is associated with premature labor and miscarriage. During vertical transmission the parasite Trypanosoma cruzi (T. cruzi) crosses the placental barrier. However, the exact mechanism of the placental infection remains unclear. We review the congenital transmission of T. cruzi, particularly the role of possible local placental factors that contribute to the vertical transmission of the parasite. Additionally, we analyze the different methods available for studying the congenital transmission of the parasite. In that context, the ex vivo infection with T. cruzi trypomastigotes of human placental chorionic villi constitutes an excellent tool for studying parasite infection strategies as well as possible local antiparasitic mechanisms.

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

    The aim of the present work was to evaluate the role of Neospora caninum and Toxoplasma gondii infections in spontaneous bovine abortions in Argentina. Based on histopathological results, 70 presumptive cases of apicomplexan protozoal abortion from a total of 666 cases of spontaneous bovine abortion submitted to the National Institute of Agrarian Technology, Balcarce, from 1999 to 2007 were included in this study. N. caninum infection was diagnosed by an indirect fluorescent antibody test (IFAT), by immunohistochemistry (IHC) and by nested-PCR. T. gondii infection also was diagnosed by nested-PCR. DNA from fetuses was extracted primarily from CNS tissues. Heart, liver, muscle and/or placenta were processed when nervous tissue was not available. Sixty-six (9.9%) fetuses were positive by at least one technique (IFAT, IHC or nested-PCR) for N. caninum infection. Overall, there was poor agreement among results obtained by these diagnostic techniques. In contrast, no Toxoplasma-infection was detected in any aborted bovine fetus. PMID:18691819

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

  9. Irish women who seek abortions in England.

    In 1991, 4158 women from Ireland and 1766 from Northern Ireland traveled to England for abortions. This situation has been ignored by Irish authorities. The 1992 case of the 14-year old seeking an abortion in England finally caught legal attention. This study attempts to help define who these abortion seekers are. Questionnaires from 200 Irish abortion seeking women attending private Marie Stopes clinics in London and the British Pregnancy Advisory Services clinic in Liverpool between September 1988 and December 1990 were analyzed. Findings pertain to demographic characteristics, characteristics of first intercourse, family discussion of sexual activity, and contraceptive use. From this limited sample, it appears that Irish women are sexually reserved and without access to modern methods of birth control and abortion. Sex is associated with shame and guilt. 23% had intercourse before the age of 18 years and 42% after the age of 20. 76% were single and 16% were currently married. 95% were Catholic; 33% had been to church the preceding Sunday and 68% within the past month. Basic information about menstruation is also limited and procedures such as dilatation and curettage may be performed selectively. 28% of married women were uninformed about menstruation prior to its onset. Only 24% had been using birth control around the time of pregnancy. The reason for nonuse was frequently the unexpectedness of intercourse. 62% of adults and 66% of women believe in legalizing abortion in Ireland. British groups have tried to break through the abortion information ban by sending telephone numbers of abortion clinics to Irish firms for distribution to employees. On November 25, 1992, in the general election, there was approval of constitutional amendments guaranteeing the right to travel for abortions and to receive information on abortion access. The amendment to allow abortion to save the life of the mother was not accepted. PMID:1483530

    The objective of this study was to determine the frequency of infectious bovine abortion and to identify some of its causes, specifically brucellosis, leptospirosis, bovine viral diarrhea, infectious bovine rhinotracheitis, and neosporosis. The study was carried out in a dairy herd in the state of Queretaro, Mexico, between September 2002 and March 2003. At the beginning of the study, blood samples were taken from a random 33% of the 300 lactating or pregnant cows; antibodies against Leptospira interrogans were the most commonly identified, in 91% of the 99 samples. Blood samples were also taken 14 to 28 d after the 26 subsequent abortions in the herd in the 6-mo study period, as well as from 22 cows that had not aborted within 5 d after the abortions in the other group. Seroconversion was most frequent for L. hardjo, occurring in 8 (67%) of the 12 dams that aborted after the initial serologic sampling and for which paired serum samples were therefore available. Of the 16 collected fetuses, 10 had histologic lesions suggesting infection in various organs, the features correlating with the serologic results for the dams in 7 cases. Thus, the abortions may have been caused by more than 1 infectious agent. PMID:17955907

  11. Clinical observations and management of a severe equine herpesvirus type 1 outbreak with abortion and encephalomyelitis

    PubMed Central

    2013-01-01

    Latent equine herpesvirus type 1 (EHV-1) infection is common in horse populations worldwide and estimated to reach a prevalence nearing 90% in some areas. The virus causes acute outbreaks of disease that are characterized by abortion and sporadic cases of myeloencephalopathy (EHM), both severe threats to equine facilities. Different strains vary in their abortigenic and neuropathogenic potential and the simultaneous occurrence of EHM and abortion is rare. In this report, we present clinical observations collected during an EHV-1 outbreak caused by a so-called “neuropathogenic” EHV-1 G2254/D752 polymerase (Pol) variant, which has become more prevalent in recent years and is less frequently associated with abortions. In this outbreak with 61 clinically affected horses, 6/7 pregnant mares aborted and 8 horses developed EHM. Three abortions occurred after development of EHM symptoms. Virus detection was performed by nested PCR targeting gB from nasal swabs (11 positive), blood serum (6 positive) and peripheral blood mononuclear cells (9 positive) of a total of 42 horses sampled. All 6 fetuses tested positive for EHV-1 by PCR and 4 by virus isolation. Paired serum neutralization test (SNT) on day 12 and 28 after the index case showed a significant (≥ 4-fold) increase in twelve horses (n = 42; 28.6%). This outbreak with abortions and EHM cases on a single equine facility provided a unique opportunity for the documentation of clinical disease progression as well as diagnostic procedures.

    This study investigated the participation of infectious agents in spontaneous abortions and reproductive problems at eight dairy cattle herds from three geographical regions of Brazil. Fourteen aborted fetuses and the organ sections of one cow with history of repeated abortions were received for pathological evaluations and molecular diagnostics. PCR/RT-PCR assays targeted specific genes of abortifacient agents of cattle: bovine viral diarrhea virus (BVDV), bovine herpesvirus 1 (BoHV-1), Listeria monocytogenes, Neospora caninum, Leptospira spp., Brucella abortus, and Histophilus somni. Six fetuses were adequate for pathological investigations; one of these did not demonstrate remarkable pathological alterations. Significant histopathological findings included vasculitis, hemorrhage, and fibrinous thrombosis of the cerebrum (n = 4); necrotizing myocarditis (n = 3); and hemorrhagic enteritis (n = 3). The placenta and uterus of the cow as well as the kidney, pancreas, and liver of her aborted fetus contained H. somni DNA and demonstrated histopathological evidence of histophilosis. All fetuses contained H. somni DNA in multiple organs. Coinfections of H. somni with B. abortus (n = 2), N. caninum (n = 2), BVDV (n = 1), and BoHV-1 (n = 1) were identified; two fetuses demonstrated three pathogens. These findings suggest that H. somni was associated with the spontaneous abortions and reproductive problems of these herds. However, the exact cause of fetal death might not be attributed only to H. somni in all aborted fetuses, since some of these were infected with other abortifacient agents. PMID:25480485

    Mosquitoes are natural vectors for many etiologic agents of human viral diseases. Mosquito-borne flaviviruses can persistently infect the mosquito central nervous system without causing dramatic pathology or influencing the mosquito behavior and lifespan. The mechanism by which the mosquito nervous system resists flaviviral infection is still largely unknown. Here we report that an Aedes aegypti homologue of the neural factor Hikaru genki (AaHig) efficiently restricts flavivirus infection of the central nervous system. AaHig was predominantly expressed in the mosquito nervous system and localized to the plasma membrane of neural cells. Functional blockade of AaHig enhanced Dengue virus (DENV) and Japanese encephalitis virus (JEV), but not Sindbis virus (SINV), replication in mosquito heads and consequently caused neural apoptosis and a dramatic reduction in the mosquito lifespan. Consistently, delivery of recombinant AaHig to mosquitoes reduced viral infection. Furthermore, the membrane-localized AaHig directly interfaced with a highly conserved motif in the surface envelope proteins of DENV and JEV, and consequently interrupted endocytic viral entry into mosquito cells. Loss of either plasma membrane targeting or virion-binding ability rendered AaHig nonfunctional. Interestingly, Culex pipien pallens Hig also demonstrated a prominent anti-flavivirus activity, suggesting a functionally conserved function for Hig. Our results demonstrate that an evolutionarily conserved antiviral mechanism prevents lethal flaviviral infection of the central nervous system in mosquitoes, and thus may facilitate flaviviral transmission in nature.

    Host genetic variations play a significant role in conferring predisposition to infection. In this study, we examined the immune mechanisms underlying the host genetic predisposition to severe Staphylococcus aureus infection in different mouse strains. Whereas C57BL/6 mice were the most resistant in terms of control of bacterial growth and survival, A/J, DBA/2, and BALB/c mice were highly susceptible and succumbed to infection shortly after bacterial inoculation. Other strains (C3H/HeN, CBA, and C57BL/10) exhibited intermediate susceptibility levels. Susceptibility of mice to S. aureus was associated with an inability to limit bacterial growth in the kidneys and development of pathology. Resistance to S. aureus in C57BL/6 mice was dependent on innate immune mechanisms because Rag2-IL2Rγ−/− C57BL/6 mice, which are deficient in B, T, and NK cells, were also resistant to infection. Indeed, neutrophil depletion or inhibition of neutrophil recruitment rendered C57BL/6 mice completely susceptible to S. aureus, indicating that neutrophils are essential for the observed resistance. Although neutrophil function is not inhibited in A/J mice, expression of neutrophil chemoattractants KC and MIP-2 peaked earlier in the kidneys of C57BL/6 mice than in A/J mice, indicating that a delay in neutrophil recruitment to the site of infection may underlie the increased susceptibility of A/J mice to S. aureus.

    Midtrimester abortion may be accomplished by a variety of techniques, alone or in combination. Comprehensive care of patients who require or request pregnancy termination in the second trimester must include careful assessment of medical and psychological conditions. Special attention needs to be paid to gestational age, and for many cases ultrasonography should be part of the evaluation. With the variety of techniques and combinations available, physicians can now individualize patient care to minimize morbidity and mortality while improving patient comfort and well being.

    To study the mechanism by which HIV-1 infects neurons we have used human neuroblastoma cell lines (NB). NB (SK-N-SH and SK-N-MC) were found to be susceptible to productive infection by X4 or R5 HIV-1, as detected by viral load and Ag-p24. To identify the putative receptor, we tested the cell surface expression of previously described receptors such as CD4, nucleolin, galactosylceramide, and CCR1, CCR5, and CXCR4 by cytometry and RT-PCR. NB express no CD4 and low levels of galactosylceramide or nucleolin. Furthermore, antibodies to any of these molecules did not affect NB infection. NB express variable levels of CCR5, CCR1, and CXCR4. Interestingly, exogenous heparan sulfate alone was able to substantially inhibit HIV-1 infection, an effect which was potentiated by RANTES or SDF-1 in the HIV-1-infection with R5 or X4 isolates. Besides, anti-CCR5 and anti-CXCR4 significantly blocked HIV-1 infection of R5 and X4 isolates. Our results suggest that HIV-1 entry involves a chemokine-receptor-dependent but CD4-independent entry in neural cells. PMID:12586555

    Ebolaviruses can cause severe hemorrhagic fever that is characterized by rapid viral replication, coagulopathy, inflammation, and high lethality rates. Although there is no clinically proven vaccine or treatment for Ebola virus infection, a virus-like particle (VLP) vaccine is effective in mice, guinea pigs, and non-human primates when given pre-infection. In this work, we report that VLPs protect Ebola virus-infected mice when given 24 hours post-infection. Analysis of cytokine expression in serum revealed a decrease in pro-inflammatory cytokine and chemokine levels in mice given VLPs post-exposure compared to infected, untreated mice. Using knockout mice, we show that VLP-mediated post-exposure protection requires perforin, B cells, macrophages, conventional dendritic cells (cDCs), and either CD4+ or CD8+ T cells. Protection was Ebola virus-specific, as marburgvirus VLPs did not protect Ebola virus-infected mice. Increased antibody production in VLP-treated mice correlated with protection, and macrophages were required for this increased production. However, NK cells, IFN-gamma, and TNF-alpha were not required for post-exposure-mediated protection. These data suggest that a non-replicating Ebola virus vaccine can provide post-exposure protection and that the mechanisms of immune protection in this setting require both increased antibody production and generation of cytotoxic T cells.

    Herpes simplex virus entry into cells requires the binding of envelope glycoprotein D (gD) to an entry receptor. Depending on the cell, entry occurs by different mechanisms, including fusion at the cell surface or endocytosis. Here we examined the entry mechanism through a non-HSV receptor mediated by a soluble bi-specific adapter protein composed of recognition elements for gD and the EGF receptor (EGFR). Virus entered into endosomes using either EGF or an EGFR-specific single chain antibody (scFv) for receptor recognition. Infection was less efficient with the EGF adapter which could be attributed to its weaker binding to a viral gD. Infection mediated by the scFv adapter was pH sensitive, indicating that gD-EGFR bridging alone was insufficient for capsid release from endosomes. We also show that the scFv adapter enhanced infection of EGFR-expressing tumor tissue in vivo. Our results indicate that adapters may retarget HSV infection without drastically changing the entry mechanism.

    Although Ghana's abortion law is fairly liberal, unsafe abortion and its consequences remain among the largest contributors to maternal mortality in the country. This study analyzes data from the 2007 Ghana Maternal Health Survey to identify the sociodemographic profiles of women who seek to induce abortion and those who are able to obtain safe abortion services. We hypothesize that women who have access to safe abortion will not be distributed randomly across different social groups in Ghana; rather, access will be influenced by social and economic factors. The results confirm this hypothesis and reveal that the women who are most vulnerable to unsafe abortions are younger, poorer, and lack partner support. The study concludes with policy recommendations for improving access to safe abortion for all subgroups of women, especially the most vulnerable. PMID:23239247

    2002-05-01

    Thanks to initiatives since 1994, most reproductive health programmes for refugee women now include family planning and safe delivery care. Emergency contraception and post-abortion care for complications of unsafe abortion are recommended, but provision of these services has lagged behind, while services for women who wish to terminate an unwanted pregnancy are almost non-existent. Given conditions in refugee settings, including high levels of sexual violence, unwanted pregnancies are of particular concern. Yet the extent of need for abortion services among refugee women remains undocumented. UNFPA estimates that 25-50% of maternal deaths in refugee settings are due to complications of unsafe abortion. Barriers to providing abortion services may include internal and external political pressure, legal restrictions, or the religious affiliation of service providers. Women too may be pressured to continue pregnancies and are often unable to express their needs or assert their rights. Abortion advocacy efforts should highlight the specific needs of refugee women and encourage provision of services where abortion is legally indicated, especially in cases of rape or incest, and risk to a woman's physical and mental health. Implementation of existing guidelines on reducing the occurrence and consequences of sexual violence in refugee settings is also important. Including refugee women in international campaigns for expanded access to safe abortion is critical in addressing the specific needs of this population. PMID:12369319

    Ethical investment funds have traditionally boycotted the arms industry, companies known to pollute the environment, and those involved in animal research. However, recent newspaper reports suggest that some investment funds plan to also boycott hospitals and pharmaceutical companies involved in abortion-related activities. Ethical Financial, anti-abortion independent financial advisors, are encouraging a boycott of investment in private hospitals and manufacturers of equipment involved in abortions, and pharmaceutical firms which produce postcoital contraception or conduct embryo research. Ethical Financial claims that Family Assurance has agreed to invest along anti-abortion lines, Aberdeen Investment is already boycotting companies linked to abortion, and Hendersons ethical fund plans to follow suit. There is speculation that Standard Life, the largest mutual insurer in Europe, will also refuse to invest in abortion-related concerns when it launches its ethical fund in the spring. Managers of ethical funds should, however, understand that, contrary to the claims of the anti-choice lobby, there is extensive public support for legal abortion, emergency contraception, and embryo research. Individuals and institutions which contribute to the development of reproductive health care services are working to alleviate the distress of unwanted pregnancy and infertility, laudable humanitarian goals which should be encouraged. Those who try to restrict the development of abortion methods and services simply show contempt for women, treating them as people devoid of conscience who are incapable of making moral choices.

Drawing upon data from a 2012 national study on postabortion-care complications and a methodology developed by the Guttmacher Institute for estimating abortion incidence, we estimate that there were 2.2 million abortions in Pakistan in 2012, an annual abortion rate of 50 per 1,000 women. A previous study estimated an abortion rate of 27 per 1,000 women in 2002. After taking into consideration the earlier study’s underestimation of abortion incidence, we conclude that the abortion rate has likely increased substantially between 2002 and 2012. Varying contraceptive-use patterns and abortion rates are found among the provinces, with higher abortion rates in Baluchistan and Sindh than in Khyber Pakhtunkhwa and Punjab. This suggests that strategies for coping with the otherwise uniformly high unintended pregnancy rates will differ among provinces. The need for an accelerated and fortified family planning program is greater than ever, as is the need to implement strategies to improve the quality and coverage of postabortion services.

    Abstract Objective To improve understanding of the attitudes, beliefs, and experiences of Muslim patients presenting for abortion. Design Exploratory study in which participants completed questionnaires about their attitudes, beliefs, and experiences. Setting Two urban, free-standing abortion clinics. Participants Fifty-three self-identified Muslim patients presenting for abortion. Main outcome measures Women’s background, beliefs, and attitudes toward their religion and toward abortion; levels of anxiety, depression, and guilt, scored on a scale of 0 to 10; and degree of pro-choice or anti-choice attitude toward abortion, assessed by having respondents identify under which circumstances a woman should be able to have an abortion. Results The 53 women in this study were a diverse group, aged 17 to 47 years, born in 17 different countries, with a range of beliefs and attitudes toward abortion. As found in previous studies, women who were less pro-choice (identified fewer acceptable reasons to have an abortion) had higher anxiety and guilt scores than more pro-choice women did: 6.9 versus 4.9 (P = .01) and 6.9 versus 3.6 (P = .004), respectively. Women who said they strongly agreed that abortion was against Islamic principles also had higher anxiety and guilt scores: 9.3 versus 5.9 (P = .03) and 9.5 versus 5.3 (P = .03), respectively. Conclusion Canadian Muslim women presenting for abortion come from many countries and schools of Islam. The group of Muslim women that we surveyed was so diverse that no generalizations can be made about them. Their attitudes toward abortion ranged from being completely pro-choice to believing abortion is wrong unless it is done to save a woman’s life. Many said they found their religion to be a source of comfort as well as a source of guilt, turning to prayer and meditation to cope with their feelings about the abortion. It is important that physicians caring for Muslim women understand that their patients come from a variety of

    Early abortion traditionally referred to abortion within 12 weeks of gestational age, but it is necessary to divide it into 3 stages: ultra early abortion for the one within 5 weeks of gestational age; very early abortion for the one within 8 weeks; early abortion for the one between 8 and 12 weeks. Progress and development in them are of IVF-ET and GIFT necessitated redefining pregnancy and resulted in great number of terms related to early pregnancy and abortion, which are not standardized and sometimes confusing. In connection with IVF-ET research, the following 3 stages of early pregnancy are recognized by Japanese doctors. Biochemical pregnancy is when plasma level of beta HCG is above norm. Early clinical pregnancy is when the Gestational sac is detected by ultrasonography but the heat beat of fetus is not yet confirmed. Established clinical pregnancy is when the heart beat of the fetus is confirmed via ultrasonography. Early abortion is divided into 2 stages: subclinical abortion (menstrual abortion), which is menstrual like fetus wastage in biomedical pregnancy, and clinical abortion in which a blighted ovum is detected by ultrasonic examination. Classification above is simple and easy but it heavily relies on measurement methods, results of which often fluctuate and are subject to change. It seems desirable to classify early abortion according to gestational age (GS). GS may be detected as early as 4 weeks, is above 10 mm in the maximum diameter at 5 weeks, and is detected in all cases at 6 weeks. Human chorionic gonadotropin (HCG) test by 1000 IU/1 sees positive response in almost all cases at 6 weeks, while HCG by 200 IU/1 sees the same at 5 weeks. The heart beat of the fetus is believed to commence at 4 weeks but it is not detected by ultrasonography at the earliest till the end of 5 weeks and in all cases till 8 weeks. The classification of ultra early abortion, very early abortion and early abortion, is based on above findings. PMID:12158570

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

    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.

    Legalization of abortion in Italy generates never ending discussions. The problem should have been solved years ago with a national campaign for family planning, with the setting up of well organized family centers, and with contraception available and free to all. If it seems right and proper to perform abortion under certain circumstances, it does not seem proper to take into consideration socioeconomic conditions, and certainly not abortion on request; a new life must not be wasted because a woman does not feel like having a new child. Abortion, on the other hand, is certainly to be considered in case of danger for the mother, in case of fetal abnormalities, or when the pregnancy is result of incest or of rape. Abortion for psychological reasons is very valid if the reasons are real, evident, and have been thoroughly evaluated. PMID:1012595

    National and international courts and tribunals are increasingly ruling that although states may aim to deter unlawful abortion by criminal penalties, they bear a parallel duty to inform physicians and patients of when abortion is lawful. The fear is that women are unjustly denied safe medical procedures to which they are legally entitled, because without such information physicians are deterred from involvement. With particular attention to the European Court of Human Rights, the UN Human Rights Committee, the Constitutional Court of Colombia, the Northern Ireland Court of Appeal, and the US Supreme Court, decisions are explained that show the responsibility of states to make rights to legal abortion transparent. Litigants are persuading judges to apply rights to reproductive health and human rights to require states' explanations of when abortion is lawful, and governments are increasingly inspired to publicize regulations or guidelines on when abortion will attract neither police nor prosecutors' scrutiny.

    Background: Skewed male:female ratios at birth have been observed among certain immigrant groups. Data on abortion practices that might help to explain these findings are lacking. Methods: We examined 1 220 933 births to women with up to 3 consecutive singleton live births between 1993 and 2012 in Ontario. Records of live births, and induced and spontaneous abortions were linked to Canadian immigration records. We determined associations of male:female infant ratios with maternal birthplace, sex of the previous living sibling(s) and prior spontaneous or induced abortions. Results: Male:female infant ratios did not appreciably depart from the normal range among Canadian-born women and most women born outside of Canada, irrespective of the sex of previous children or the characteristics of prior abortions. However, among infants of women who immigrated from India and had previously given birth to 2 girls, the overall male:female ratio was 1.96 (95% confidence interval [CI] 1.75–2.21) for the third live birth. The male:female infant ratio after 2 girls was 1.77 (95% CI 1.26–2.47) times higher if the current birth was preceded by 1 induced abortion, 2.38 (95% CI 1.44–3.94) times higher if preceded by 2 or more induced abortions and 3.88 (95% CI 2.02–7.50) times higher if the induced abortion was performed at 15 weeks or more gestation relative to no preceding abortion. Spontaneous abortions were not associated with male-biased sex ratios in subsequent births. Interpretation: High male:female ratios observed among infants born to women who immigrated from India are associated with induced abortions, especially in the second trimester of pregnancy.

We now appreciate that the utility of viruses for treating cancer extends far beyond lytic cell death. Viruses are also capable of eliciting humoral and cellular innate and adaptive immune responses that may be directed not only at virus-infected cells but also at uninfected cancer cells. Here we review our current understanding of this bystander effect, and divide the mechanisms into lytic, cytokine, innate cellular, and adaptive phases. Knowing the key pathways and molecular players during virus infection in the context of the cancer microenvironment will be critical to devise strategies to maximize the therapeutic effects of oncolytic viroimmunotherapy.

    An inactivated saponine vaccine is prepared from five highly immunogenic Salmonella abortus ovis strains, selected by means of a biological test on white rats. Saline was used as a diluent of the vaccine, with the addition of 30 per cent glycerine, 0.012 per cent saponine and 0.1 per cent propiolactone. The optimum immunization dose of 5 cm3 is injected singly subcutaneously behind the elbow, two and a half months after impregnation. The vaccine is applied on infected farms before the disease occurs. The cellular-humoral immunity, which forms 14 days after the injection, lasts 4--5 months and protects the sheep against salmonellosis abortion. PMID:571645

    Campylobacter infection is a leading cause of ovine abortion worldwide. Historically, genetically diverse Campylobacter fetus and Campylobacter jejuni strains have been implicated in such infections, but since 2003 a highly pathogenic, tetracycline-resistant C. jejuni clone (named SA) has become the predominant cause of sheep abortions in the United States. Whether clone SA was present in earlier U.S. abortion isolates (before 2000) and is associated with sheep abortions outside the United States are unknown. Here, we analyzed 54 C. jejuni isolates collected from U.S. sheep abortions at different time periods and compared them with 42 C. jejuni isolates associated with sheep abortion during 2002 to 2008 in Great Britain, using multilocus sequence typing (MLST), pulsed-field gel electrophoresis (PFGE), and array-based comparative genomic hybridization (CGH). Although clone SA (ST-8) was present in the early U.S. isolates, it was not as tetracycline resistant (19% versus 100%) or predominant (66% versus 91%) as it was in the late U.S isolates. In contrast, C. jejuni isolates from Great Britain were genetically diverse, comprising 19 STs and lacking ST-8. PFGE and CGH analyses of representative strains further confirmed the population structure of the abortion isolates. Notably, the Great Britain isolates were essentially susceptible to most tested antibiotics, including tetracycline, while the late U.S. isolates were universally resistant to this antibiotic, which could be explained by the common use of tetracyclines for control of sheep abortions in the United States but not in Great Britain. These results suggest that the dominance of clone SA in sheep abortions is unique to the United States, and the use of tetracyclines may have facilitated selection of this highly pathogenic clone.

    Induced abortion is an urgent public health problem that can be controlled if it is approached in its true complexity and with a social and humanist perspective. Induced abortion has been discussed in Chile since the last century, but not always openly. Abortion is not just an individual and collective medical problem, it is also an ethical, religious, legal, demographic, political, and psychological problem. Above all it is a problem of human rights. In the past 60 years, more than 50 countries representing 76% of the world population have liberalized their abortion legislation. Around 980 million women have some degrees of access of legal abortion. The magnitude of illegal abortion is difficult to determine because of the desire of women to hide their experiences. Estimates of the incidence of abortion in Chile made some 25 years ago are no longer valid because of the numerous social changes in the intervening years. The number of abortions in Chile in 1987 was estimated using an indirect residual method at 195,441, of which 90%, or 175,897, were induced. By this estimate, 38.8% of pregnancies in Chile end in abortion. Data on hospitalizations for complications of induced abortion show an increase from 13.9/1000 fertile aged women in 1940 to 29.1 in 1965. By 1987, with increased contraceptive usage, the rate declined to 10.5 abortions per 1000 fertile aged women. The cost of hospitalization for abortion complications in 1987, despite the decline, was still estimated at US $4.3 million, a large sum in an era of declining health resources. The problem of induced abortion can be analyzed by placing it in the context of elements affecting the desire to control fertility. 4 complexes of variables are involved: those affecting the supply of contraceptive, the demand for contraceptives, the various costs of fertility control measure, and alternatives to fertility control for satisfying various needs. The analysis is further complicated when efforts are made to

    Neospora caninum is one of the most frequent infectious organisms causing abortion in cattle worldwide. The present case-control study was designed to assess the importance of bovine neosporosis for causing abortion in Swiss cattle and to identify selected risk factors. Infection was primarily diagnosed by a N. caninum-specific PCR and serology, complemented with histopathology and immunohistochemistry. A total of 113 case and 113 corresponding control-farms were studied for 1.5 year. During this time period, 242 abortions were reported and referred for bacteriological, virological, parasitological and pathohistological examinations. N. caninum was detected by PCR in the brains of 21% of all aborted fetuses. Microscopic lesions indicative for cerebral protozoa infection were detected in 84% of PCR-positive fetal brains. Bovine viral diarrhea virus (BVDV) was demonstrated in 7% of the cases, and bacterial infections were detected in 4% of the abortions. One or more N. caninum-abortions occurred in 20% of the herds (41 case-farms and 3 control-farms). Serological examination of aborting mother cows revealed a significantly higher percentage of N. caninum-seropositive animals (44%) in comparison to the prevalence in a randomly selected population (12%). However, in eight cases (4% of all investigated abortions) seronegative cows aborted N. caninum PCR-positive fetuses, and in 50 cases the fetus remained negative although the respective mother cow was N. caninum-seropositive. Repetitive serological investigations (at a 3-12 months interval) of 3551 cows from case- and control-farms showed a decrease of the overall N. caninum-seroprevalence from 17 to 12%. Ninety out of 3008 seronegative animals were converted to N. caninum-seropositivity. Conversely, 212 out of 543 initially seropositive animals became seronegative for their second serum sample. The obtained data underlined the importance of N. caninum as a causative agent for abortion in Swiss cattle. Furthermore, PCR

    Cryptococcus neoformans is a medically important opportunistic fungal pathogen with a polysaccharide capsule surrounding the yeast-like cells. In hosts with impaired cell-mediated immunity such as AIDS, uncontrolled infection causes life-threatening meningoencephalitis. In immunocompetent individuals, the host immune response usually limits the growth of the fungal pathogen at the primary infected site, where it may persist, without completely eradicated, in a latent state because of its ability to escape from killing by macrophages. Th1 response in adaptive immunity is essential for the host defense to cryptococcal infection, in which interferon (IFN)-γ polarizes innate macrophages into fungicidal M1 macrophages. Recently, we found that caspase recruitment domain family member (CARD9), an adaptor protein in a signal transduction triggered by C-type lectin receptors, plays a key role in the early production of IFN-γ at the site of infection by recruiting NK cells and CD4(+) and CD8(+) memory-phenotype T cells. We also found that IL-4 produced by Th2 cells stimulates broncoepithelial cells to secrete mucin, which may lead to promotion in the mucociliary clearance of C. neoformans. Here, we summarize the up-to-date findings in the host defense mechanism to this infection with focusing on our recent data. PMID:25231225

    Bacterial infections of the endometrium after parturition commonly cause metritis and endometritis in dairy cattle, and these diseases are important because they compromise animal welfare and incur economic costs, as well as delaying or preventing conception. Here we highlight that uterine infections cause infertility, discuss which bacteria cause uterine disease, and review the evidence for mechanisms of inflammation and tissue damage in the endometrium. Bacteria cultured from the uterus of diseased animals include Escherichia coli, Trueperella pyogenes, and several anaerobic species, but their causative role in disease is challenged by the discovery of many other bacteria in the uterine disease microbiome. Irrespective of the species of bacteria, endometrial cell inflammatory responses to infection initially depend on innate immunity, with Toll-like receptors binding pathogen-associated molecular patterns, such as lipopolysaccharide and bacterial lipopeptides. In addition to tissue damage associated with parturition and inflammation, endometrial cell death is caused by a cholesterol-dependent cytolysin secreted by T. pyogenes, called pyolysin, which forms pores in plasma membranes of endometrial cells. However, endometrial cells surprisingly do not sense damage-associated molecular patterns, but a combination of infections followed by cell damage leads to release of the intracellular cytokine interleukin (IL)-1 alpha from endometrial cells, which then acts to scale inflammatory responses. To develop strategies to limit the impact of uterine disease on fertility, future work should focus on determining which bacteria and virulence factors cause endometritis, and understanding how the host response to infection is regulated in the endometrium.

  9. Mechanics governs single-cell signaling and multi-cell robustness in biofilm infections

    NASA Astrophysics Data System (ADS)

    Gordon, Vernita

    In biofilms, bacteria and other microbes are embedded in extracellular polymers (EPS). Multiple types of EPS can be produced by a single bacterial strain - the reasons for this redundancy are not well-understood. Our work suggests that different polymers may confer distinct mechanical benefits. Our model organism is Pseudomonas aeruginosa, an opportunistic human pathogen that forms chronic biofilm infections associated with increased antibiotic resistance and evasion of the immune defense. Biofilms initiate when bacteria attach to a surface, sense the surface, and change their gene expression. Changes in gene expression are regulated by a chemical signal, cyclic-di-GMP. We find that one EPS material, called ``PEL,'' enhances surface sensing by increasing mechanical coupling of single bacteria to the surface. Measurements of bacterial motility suggest that PEL may increase frictional interactions between the surface and the bacteria. Consistent with this, we show that bacteria increase cyclic-di-GMP signaling in response to mechanical shear stress. Mechanosensing has long been known to be important to the function of cells in higher eukaryotes, but this is one of only a handful of studies showing that bacteria can sense and respond to mechanical forces. For the mature biofilm, the embedding polymer matrix can protect bacteria both chemically and mechanically. P. aeruginosa infections in the cystic fibrosis (CF) lung often last for decades, ample time for the infecting strain(s) to evolve. Production of another EPS material, alginate, is well-known to tend to increase over time in CF infections. Alginate chemically protects biofilms, but also makes them softer and weaker. Recently, it is being increasingly recognized that bacteria in chronic CF infections also evolve to increase PSL production. We use oscillatory bulk rheology to determine the unique contributions of EPS materials to biofilm mechanics. Unlike alginate, increased PSL stiffens biofilms. Increasing both

    In September 1993, a two-day symposium on abortion legalization was held in Chile, where abortion, which had been legal since the 1930s, was banned by the outgoing military junta in 1989. Organizers of the symposium labeled the ban "a law to punish and to be flaunted," and, indeed, each year approximately 200,000 Chilean women resort to abortion and more than 30,000 are hospitalized for abortion complications. It has been estimated that one woman has died of abortion complications in Chile each week for the past five years. Legislation proposed in 1991 to reinstate therapeutic abortion has stalled because of broad spectrum political opposition, pressure from the Roman Catholic Church, and upcoming elections. In this politically hostile climate, 43% of respondents in a poll said abortion should be permitted in certain cases, 3% said it should be available to all women, and nearly 53% upheld the ban. Research on public support for abortion has indicated that opinions about abortion depend upon the phrasing of the questions and that women's attitudes towards abortion are shaped by their experiences and those of their relatives and friends rather than by legal or religious prohibitions.

    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. PMID:26078881

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

    On November 26-28, 1992, the Latin American and Caribbean Women's Health Network convened a meeting in Uruguay entitled, "Abortion in Latin America: Perspectives and Strategies." The first session was devoted to discussion of a paper that argues that a feminist ethic must be developed to counteract the dominant patriarchal ethic, which fails to improve women's lives. The next session covered the World Bank's concerns about the economic consequences of illegal abortion. The third session included descriptions of the experiences of the coordinator of the Sao Paulo Municipal Women's Health Program and of the new Argentine National Women's Health Network. Debate and discussion were generated by the next speaker, who presented a legislative proposal for the decriminalization of abortion in Latin America and noted that restrictive policies, which have failed to reduce abortion rates, will be difficult to change. It was proposed that regional campaigns be launched to legalize abortion as a first step in achieving reproductive rights for women. After a review of abortion-related activities in the region during the past year, participants composed a five-year plan of action in the areas of research, data centralization, petition campaigns, and publication of a review of abortion legislation. Finally, it was proposed that a counselor training course in sexual and reproductive rights be developed. PMID:12179717

  19. The abortion debate: measuring gestational age.

    PubMed

    Santee, B; Henshaw, S K

    1992-01-01

    Abortion statistics are flawed by the lack of consistency in reporting gestational age. Several methods are generally used, and the number of abortions occurring before 12 weeks changes considerably depending upon the method used to determine gestational age. Pregnancy can be measured from the beginning of last menstruation or from fertilization, which is 14 days after the 1st day of the last menstrual period. Neither method accurately records pregnancy as determined by specialists in embryology and fetal development. Pregnancy actually begins with implantation, which begins 6-7 days after fertilization and ends 10-14 days later. Completion of fertilization and implantation occurs as much as 28 days after the 1st day of the last menstrual period. A report of an 8-week pregnancy is actually 6 weeks from fertilization and 4-5 weeks from implantation. The Centers for Disease Control and other abortion data collecting agencies use the 1st day of the last menstrual period. Statistics generally show that 50% of abortions occur before 8 weeks of gestation and 90% by 12 weeks. When gestation is considered at fertilization, 78% of abortions occur under 9 weeks, while 52% of abortions under 9 weeks are performed with data beginning at the 1st day of the last menstrual period. For abortions occurring under 12 weeks, 95% beginning at fertilization and 90% occur at the 1st day of the last menstrual period. 2/1000 vs. 5/1000 abortions occur under 20 weeks for data beginning at fertilization vs. at the onset of the last period. It is important to report abortion data accurately and to specify the method used to determine the gestational time period. PMID:1526273

    1986-02-01

    Since the 1973 Supreme Court decision legalizing abortion, medical and scientific developments have focused greater public and professional attention on the status of the fetus. Their cumulative effect may influence legal, social, and moral thought and set the stage for a change in public opinion and a challenge to legalized abortion. There is as yet no inexorable convergence of medical data and legal opinion that would undermine the rational of Roe v. Wade. But the prochoice movement must find room for an open airing of the moral questions if abortion is to remain what it should be--a legally acceptable act. PMID:3514547

  1. The Marquis de Sade and induced abortion.

    PubMed

    Farr, A D

    1980-03-01

    In 1795 the Marquis de Sade published his La Philosophic dans le boudoir, in which he proposed the use of induced abortion for social reasons and as a means of population control. It is from this time that medical and social acceptance of abortion can be dated, although previously the subject had not been discussed in public in modern times. It is suggested that it was largely due to de Sade's writing that induced abortion received the impetus which resulted in its subsequent spread in western society. PMID:6990001

    ABSTRACT Cryptococcus neoformans is a pathogenic yeast and a leading cause of life-threatening meningitis in AIDS patients. Natural killer (NK) cells are important immune effector cells that directly recognize and kill C. neoformans via a perforin-dependent cytotoxic mechanism. We previously showed that NK cells from HIV-infected patients have aberrant anticryptococcal killing and that interleukin-12 (IL-12) restores the activity at least partially through restoration of NKp30. However, the mechanisms causing this defect or how IL-12 restores the function was unknown. By examining the sequential steps in NK cell killing of Cryptococcus, we found that NK cells from HIV-infected patients had defective binding of NK cells to C. neoformans. Moreover, those NK cells that bound to C. neoformans failed to polarize perforin-containing granules to the microbial synapse compared to healthy controls, suggesting that binding was insufficient to restore a defect in perforin polarization. We also identified lower expression of intracellular perforin and defective perforin release from NK cells of HIV-infected patients in response to C. neoformans. Importantly, treatment of NK cells from HIV-infected patients with IL-12 reversed the multiple defects in binding, granule polarization, perforin content, and perforin release and restored anticryptococcal activity. Thus, there are multiple defects in the cytolytic machinery of NK cells from HIV-infected patients, which cumulatively result in defective NK cell anticryptococcal activity, and each of these defects can be reversed with IL-12.

    Abortion in dairy cattle causes considerable economic losses to the dairy industry. Aborted fetuses and samples from the corresponding aborting dams from 12 dairy herds in Beijing were tested for 9 abortifacient infectious pathogens by PCR between 2008 and 2010. From a total of 80 abortion cases collected during this period, infectious agents were detected in 45 (56.3%) cases, 22 (48.9%) of which represented co-infections with two or three infectious agents. The detected pathogens included infectious bovine rhinotracheitis virus (36.3%) and Neospora caninum (31.3%), followed by bovine viral diarrhoea virus (7.5%), Brucella abortus (6.3%), Tritrichomonas foetus (5%) and Toxoplasma gondii (1.3%). Campylobacter fetus, Coxiella burnetii and Chlamydophila psittaci were not detected in any abortion case. Findings from this study indicated that infectious bovine rhinotracheitis virus and Neospora caninum were the main potential causes of abortions in Beijing dairy herds, whereas the bacterial pathogens were not, in contrast to reports from other countries. This is the first study to test nine abortifacient infectious agents by PCR at the same time, and it is also the first time to report the involvement of a variety of infectious agents in bovine abortion cases in China.

    A nationally representative survey was conducted among 3000 Catholics in Mexico during 2009 and 2010. Respondents were presented with a hypothetical situation about a young woman who decided to have an abortion and were asked their personal opinion of her. On the basis of a stigma index, it was found that the majority (61%) had stigmatizing attitudes about abortion; however, 81% believed that abortion should be legal in at least some circumstances. Respondents were significantly more likely to stigmatize abortion if they disagreed with the Mexico City law legalizing the procedure (odds ratio 1.66; 95% CI, 1.30-2.11) and believed that abortion should be prohibited in all cases (odds ratio 3.13; 95% CI, 2.28-4.30). Such stigma can lead women to seek unsafe abortions to avoid judgment by society. PMID:22920621

  5. The effect of enterohemorrhagic E. coli infection on the cell mechanics of host cells.

    Enterohaemorrhagic E. coli (EHEC) is a type of human pathogenic bacteria. The main virulence characteristics of EHEC include the formation of attaching and effacing lesions (A/E lesions) and the production of one or more Shiga-like toxins, which may induce human uremic complications. When EHEC infects host cells, it releases translocated intimin receptor (Tir) and effector proteins inside the host cells, inducing the rearrangement and accumulation of the F-actin cytoskeleton, a phenotype leading to the formation of pedestals in the apical cell surface, and the growth of stress fibers at the base of the cells. To examine the effect of EHEC infection on cell mechanics, we carried out a series of experiments to examine HeLa cells with and without EHEC infection to quantify the changes in (1) focal adhesion area, visualized by anti-vinculin staining; (2) the distribution and orientation of stress fibers; and (3) the intracellular viscoelasticity, via directional video particle tracking microrheology. Our results indicated that in EHEC-infected HeLa cells, the focal adhesion area increased and the actin stress fibers became thicker and more aligned. The cytoskeletal reorganization induced by EHEC infection mediated a dramatic increase in the cytoplasmic elastic shear modulus of the infected cells, and a transition in the viscoelastic behavior of the cells from viscous-like to elastic-like. These changes in mechanobiological characteristics might modulate the attachments between EHEC and the host cell to withstand exfoliation, and between the host cell and the extracellular matrix, and might also alter epithelial integrity.

    OBJECTIVE: To identify factors associated with increased risk of immediate complications from induced abortion. DESIGN: Retrospective analysis of a provincial database. SETTING: All Ontario general hospitals in which abortions are performed and all free-standing abortion clinics in Ontario. POPULATION: Women in Ontario aged 15 to 44 years who underwent an induced abortion in the province (without concurrent sterilization) between Jan. 1, 1992, and Dec. 31, 1993. OUTCOME MEASURES: Recording of complications at the time of the procedure, gestational age, type of procedure, place of abortion (hospital or clinic), and patient's age, parity and history of previous abortion (spontaneous or induced). RESULTS: During the study period 83 469 abortions were performed that met our inclusion criteria. Immediate complications were reported in 571 cases (0.7%). Multivariate logistic regression analysis revealed that, after other variables were controlled for, the patient's age, parity and history of previous abortions (spontaneous or induced) were not significant risk factors for immediate complications; however, gestational age, method of abortion and place of abortion were significant risk factors (p < 0.001). The odds ratio (OR) for having a complication from abortion was 1.3 (95% confidence interval [CI] 1.02 to 1.63) between 9 and 12 weeks, compared with having one after abortion at 9 weeks or earlier, and increased to 3.3 (95% CI 2.23 to 5.00) after abortion between 17 and 20 weeks. Compared with surgical dilatation and curettage (D&C), instillation of saline and instillation of prostaglandins were more likely to be associated with immediate complications (OR 24.0, 95% CI 13.22 to 43.70, and OR 11.7, 95% CI 6.43 to 21.18, respectively), whereas both suction D&C and insertion of a laminaria tent were less likely to be associated with immediate complications (OR 0.4, 95% CI 0.26 to 0.67, and OR 0.3, 95% CI 0.19 to 0.52, respectively). Compared with women who had an abortion

    First-trimester surgical abortion is a common, safe procedure with a major complication rate of less than 1%. Cervical dilation before suction abortion is usually accomplished using tapered mechanical dilators. Risk factors for major complications in the first trimester include increasing gestational age and provider inexperience. Cervical priming before first-trimester surgical abortion has been studied using osmotic dilators and pharmacologic agents, most commonly misoprostol. Extensive data demonstrate that a variety of agents are safe and effective at causing preoperative cervical softening and dilation; however, given the small absolute risk of complications, the benefit of routine use of misoprostol or osmotic dilators in first-trimester surgical abortion is unclear. Although cervical priming results in reduced abortion time and improved provider ease, it requires a delay of at least 1 to 3 h and may confer side effects. The Society of Family Planning does not recommend routine cervical priming for first-trimester suction abortion but recommends limiting consideration of cervical priming for women at increased risk of complications from cervical dilation, including those late in the first trimester, adolescents and women in whom cervical dilation is expected to be challenging.

    Objective(s) The purpose of this thematic analysis is to describe recruitment, retention, and career development strategies for expert nurses in abortion care provision. Study Design Thematic analysis influenced by grounded theory methods were used to analyze interviews, which examined cognitive, emotional, and behavioral processes associated with how nurses make decisions about participation in abortion care provision. The purposive sample consisted of 16 nurses, who were interviewed between November, 2012 and August, 2013, who work (or have worked) with women seeking abortions in abortion clinics, emergency departments, labor and delivery units, and post anesthesia care units. Results Several themes emerged from the broad categories that contribute to successful nurse recruitment, retention, and career development in abortion care provision. All areas were significantly influenced by engagement in leadership activities and professional society membership. The most notable theme specific to recruitment was exposure to abortion through education as a student, or through an employer. Retention is most influenced by flexibility in practice, including: advocating for patients, translating one's skill set, believing that nursing is shared work, and juggling multiple roles. Lastly, providing on the job training opportunities for knowledge and skill advancement best enables career development. Conclusion(s) Clear mechanisms exist to develop expert nurses in abortion care provision. Implications The findings from our study should encourage employers to provide exposure opportunities, develop activities to recruit and retain nurses, and to support career development in abortion care provision. Additionally, future workforce development efforts should include and engage nursing education institutions and employers to design structured support for this trajectory. PMID:25708505

    Abortion rates in Russia, particularly repeat abortions, are among the highest in the world, and abortion complications make a substantial contribution to the country's high maternal mortality rate. Russia also has a very high rate of hazardous alcohol use. However, the association between alcohol use and abortion in Russia remains unexplored. We investigated the longitudinal predictors of first and repeat abortion, focussing on women's alcohol use as a risk factor. Follow-up data from 2,623 women of reproductive age (16–44 years) was extracted from 14 waves of the Russian Longitudinal Monitoring Survey (RLMS), a nationally representative panel study covering the period 1994–2009. We used discrete time hazard models to estimate the probability of having a first and repeat abortion by social, demographic and health characteristics at the preceding study wave. Having a first abortion was associated with demographic factors such as age and parity, whereas repeat abortions were associated with low education and alcohol use. After adjustment for demographic and socioeconomic factors, the risk of having a repeat abortion increased significantly as women's drinking frequency increased (P<0.001), and binge drinking women were significantly more likely to have a repeat abortion than non-drinkers (OR 2.28, 95% CI 1.62–3.20). This association was not accounted for by contraceptive use or a higher risk of pregnancy. Therefore the determinants of first and repeat abortion in Russia between 1994–2009 were different. Women who had repeat abortions were distinguished by their heavier and more frequent alcohol use. The mechanism for the association is not well understood but could be explained by unmeasured personality factors, such as risk taking, or social non-conformity increasing the risk of unplanned pregnancy. Heavy or frequent drinkers constitute a particularly high risk group for repeat abortion, who could be targeted in prevention efforts. PMID:24671000

    The tripartite motif protein 21 (TRIM21) is a ubiquitously expressed E3 ubiquitin ligase and an intracellular antibody receptor. TRIM21 mediates antibody-dependent intracellular neutralization (ADIN) in cytosol and provides an intracellular immune response to protect host defense against pathogen infection. In this study, swine TRIM21 (sTRIM21) was cloned and its role in ADIN was investigated. The expression of sTRIM21 is induced by type I interferon in PK-15 cells. sTRIM21 restricts FMDV infection in the presence of FMDV specific antibodies. Furthermore, sTRIM21 interacts with Fc fragment of swine immunoglobulin G (sFc) fused VP1 of FMDV and thereby causing its degradation. Both the RING and SPRY domains are essential for sTRIM21 to degrade sFc-fused VP1. These results suggest that the intracellular neutralization features of FMDV contribute to the antiviral activity of sTRIM21. sTRIM21 provide another intracellular mechanism to inhibit FMDV infection in infected cells.

    2013-01-01

    Objective To evaluate the implementation of state Medicaid abortion policies and the impact of these policies on abortion clients and abortion providers. Data Source From 2007 to 2010, in-depth interviews were conducted with representatives of 70 abortion-providing facilities in 15 states. Study Design In-depth interviews focused on abortion providers' perceptions regarding Medicaid and their experiences working with Medicaid and securing reimbursement in cases that should receive federal funding: rape, incest, and life endangerment. Data Extraction Data were transcribed verbatim before being coded. Principal Findings In two study states, abortion providers reported that 97 percent of submitted claims for qualifying cases were funded. Success receiving reimbursement was attributed to streamlined electronic billing procedures, timely claims processing, and responsive Medicaid staff. Abortion providers in the other 13 states reported reimbursement for 36 percent of qualifying cases. Providers reported difficulties obtaining reimbursement due to unclear rejections of qualifying claims, complex billing procedures, lack of knowledgeable Medicaid staff with whom billing problems could be discussed, and low and slow reimbursement rates. Conclusions Poor state-level implementation of Medicaid coverage of abortion policies creates barriers for women seeking abortion. Efforts to ensure policies are implemented appropriately would improve women's health. PMID:22742741

    Background Nontyphoidal strains of Salmonella are a leading cause of death among HIV-infected Africans. Antibody-induced complement-mediated killing protects healthy Africans against Salmonella, but increased levels of anti-lipopolysaccharide (LPS) antibodies in some HIV-infected African adults block this killing. The objective was to understand how these high levels of anti-LPS antibodies interfere with the killing of Salmonella. Methodology/Principal Findings Sera and affinity-purified antibodies from African HIV-infected adults that failed to kill invasive S. Typhimurium D23580 were compared to sera from HIV-uninfected and HIV-infected subjects with bactericidal activity. The failure of sera from certain HIV-infected subjects to kill Salmonella was found to be due to an inherent inhibitory effect of anti-LPS antibodies. This inhibition was concentration-dependent and strongly associated with IgA and IgG2 anti-LPS antibodies (p<0.0001 for both). IgG anti-LPS antibodies, from sera of HIV-infected individuals that inhibit killing at high concentration, induced killing when diluted. Conversely, IgG, from sera of HIV-uninfected adults that induce killing, inhibited killing when concentrated. IgM anti-LPS antibodies from all subjects also induced Salmonella killing. Finally, the inhibitory effect of high concentrations of anti-LPS antibodies is seen with IgM as well as IgG and IgA. No correlation was found between affinity or avidity, or complement deposition or consumption, and inhibition of killing. Conclusion/Significance IgG and IgM classes of anti-S. Typhimurium LPS antibodies from HIV-infected and HIV-uninfected individuals are bactericidal, while at very high concentrations, anti-LPS antibodies of all classes inhibit in vitro killing of Salmonella. This could be due to a variety of mechanisms relating to the poor ability of IgA and IgG2 to activate complement, and deposition of complement at sites where it cannot insert in the bacterial membrane.

    Maternal mortality and morbidity are the leading causes of death and illness, respectively, among women of reproductive age in many countries throughout the world. Of all maternal deaths, those related to unsafe abortions are the most widely underestimated, but they are also the most largely preventable. Medical abortion is a safe and reliable method for termination of a pregnancy in early gestation, although it is important to be aware of signs and symptoms of severe infection and toxic shock syndrome after the medical termination of pregnancy; case studies in literature are rarely fatal events. We report the first case of septic shock syndrome following a clandestine pregnancy termination with a misoprostol-only regimen (12 tablets 200 μg each). Autopsy findings and histopathological examination proved that the woman died from septic shock. This case suggests to improve the forensic investigations in case of unsafe, often clandestine, abortion is suspected. PMID:25041279

    Diabetes has been recognized as an important risk factor for a variety of intracellular bacterial infections, but research into the dysregulated immune mechanisms contributing to the impaired host–pathogen interactions is in its infancy. Diabetes is characterized by a chronic state of low-grade inflammation due to activation of pro-inflammatory mediators and increased formation of advanced glycation end products. Increased oxidative stress also exacerbates the chronic inflammatory processes observed in diabetes. The reduced phagocytic and antibacterial activity of neutrophils and macrophages provides an intracellular niche for the pathogen to replicate. Phagocytic and antibacterial dysfunction may be mediated directly through altered glucose metabolism and oxidative stress. Furthermore, impaired activation of natural killer cells contributes to decreased levels of interferon-γ, required for promoting macrophage antibacterial mechanisms. Together with impaired dendritic cell function, this impedes timely activation of adaptive immune responses. Increased intracellular oxidation of antigen-presenting cells in individuals with diabetes alters the cytokine profile generated and the subsequent balance of T-cell immunity. The establishment of acute intracellular bacterial infections in the diabetic host is associated with impaired T-cell-mediated immune responses. Concomitant to the greater intracellular bacterial burden and potential cumulative effect of chronic inflammatory processes, late hyper-inflammatory cytokine responses are often observed in individuals with diabetes, contributing to systemic pathology. The convergence of intracellular bacterial infections and diabetes poses new challenges for immunologists, providing the impetus for multidisciplinary research. PMID:25262977

    Rodriguez, K; Strickler, J

    1999-01-01

    This paper presents the results of in-depth interviews with ten clandestine abortion providers in urban Latin America. Three related issues are addressed: how abortion providers come to this line of work; their major difficulties; and their sources of job satisfaction. A variety of paths bring health professionals to the practice of abortion; common elements are a sense of calling, a desire to help women, personal experience with abortion, and a commitment to political change. Providers describe difficulties that include a lack of medical support, the need for secrecy, and threats of violence, extortion, and prosecution. In spite of difficulties, all providers report a great deal of fulfillment in their work, based on their satisfaction in saving women's lives, maintaining supportive relationships with colleagues, and empowering women.

  20. South African parliament approves sweeping abortion reform.

    PubMed

    1996-11-22

    South Africa's National Assembly voted 209 to 87 for passage of the "Choice on Termination of Pregnancy Act" on October 30; it was passed in the Senate, 49 to 21 (20 abstentions), on November 5. The African National Congress strongly supported the Act, while the National Party opposed it. Under the law, abortions during the first 12 weeks of pregnancy may to be performed by physicians or trained midwives. From week 13 through week 20, a physician, in consultation with the mother, may terminate the pregnancy after determining that continuing the pregnancy would threaten the woman's health (physical or mental) or circumstances (social or economic), or that the fetus is at substantial risk of suffering severe physical or mental abnormalities. Abortion is permitted after 20 weeks if two doctors (or midwives) decide continuing the pregnancy would endanger the mother's life or result in injury or severe malformation of the fetus. Only the pregnant woman's consent is required. Although an abortion provider must advise a young client to consult with parents, guardian, family members, or friends before the procedure, she is not required to comply. All women are to be informed of their rights under the Act; criminal penalties (up to 10 years) are mandated for unauthorized abortion providers, for persons who prevent a lawful abortion, or for those who obstruct access to an abortion facility. The new statute repeals the more restrictive Abortion and Sterilization Act of 1975, which permitted abortion only in cases of maternal life or health endangerment, severe fetal abnormality, rape, incest, or mental incapacity.

    Stigma taints individuals with a spoiled identity and loss of status or discrimination. This article is the first to examine the stigma attached to abortion and surrogacy and consider how law may stigmatize women for failing to conform to social expectations about maternal roles. Courts should consider evidence of stigma when evaluating laws regulating abortion or surrogacy to determine whether these laws are based on impermissible gender stereotyping. PMID:26242937

    Sixty-seven women were interviewed four weeks after spontaneous abortion. As determined by the Present State Examination, 32 of these women were psychiatric cases. This rate is four times higher than in the general population of women. In each case the diagnosis was depressive disorder, a finding confirmed by scores on three depression rating scales. Many women showed typical features of grief. Depressive symptoms were significantly associated with a history of previous spontaneous abortion, and less so with childlessness. PMID:2620207

    HIV infection of the CNS is an early event after primary infection, resulting in neurological complications in a significant number of individuals despite antiretroviral therapy (ART). The main cells infected with HIV within the CNS are macrophages/microglia and a small fraction of astrocytes. The role of these few infected astrocytes in the pathogenesis of neuroAIDS has not been examined extensively. Here, we demonstrate that few HIV-infected astrocytes (4.7 ± 2.8% in vitro and 8.2 ± 3.9% in vivo) compromise blood-brain barrier (BBB) integrity. This BBB disruption is due to endothelial apoptosis, misguided astrocyte end feet, and dysregulation of lipoxygenase/cyclooxygenase, BK(Ca) channels, and ATP receptor activation within astrocytes. All of these alterations in BBB integrity induced by a few HIV-infected astrocytes were gap junction dependent, as blocking these channels protected the BBB from HIV-infected astrocyte-mediated compromise. We also demonstrated apoptosis in vivo of BBB cells in contact with infected astrocytes using brain tissue sections from simian immunodeficiency virus-infected macaques as a model of neuroAIDS, suggesting an important role for these few infected astrocytes in the CNS damage seen with HIV infection. Our findings describe a novel mechanism of bystander BBB toxicity mediated by low numbers of HIV-infected astrocytes and amplified by gap junctions. This mechanism of toxicity contributes to understanding how CNS damage is spread even in the current ART era and how minimal or controlled HIV infection still results in cognitive impairment in a large population of infected individuals.

  4. Abortion and anxiety: what's the relationship?

    Using data from the United States National Survey of Family Growth (NSFG) and the National Comorbidity Survey (NCS), we conducted secondary data analyses to examine the relationship of abortion, including multiple abortions, to anxiety after first pregnancy outcome in two studies. First, when analyzing the NSFG, we found that pre-pregnancy anxiety symptoms, rape history, age at first pregnancy outcome (abortion vs. delivery), race, marital status, income, education, subsequent abortions, and subsequent deliveries accounted for a significant association initially found between first pregnancy outcome and experiencing subsequent anxiety symptoms. We then tested the relationship of abortion to clinically diagnosed generalized anxiety disorder (GAD), post-traumatic stress disorder (PTSD), and social anxiety disorder, using NCS data. Contrary to findings from our analyses of the NSFG, in the NCS analyses we did not find a significant relationship between first pregnancy outcome and subsequent rates of GAD, social anxiety, or PTSD. However, multiple abortions were found to be associated with much higher rates of PTSD and social anxiety; this relationship was largely explained by pre-pregnancy mental health disorders and their association with higher rates of violence. Researchers and clinicians need to learn more about the relations of violence exposure, mental health, and pregnancy outcome to avoid attributing poor mental health solely to pregnancy outcomes.

  5. The abortion debate in the Dominican Republic.

    PubMed

    1992-01-01

    Faced with a situation in which an estimated 60,000 illegal abortions (a major cause of maternal mortality) were performed annually, the Dominican Republic has adopted a new Health Code which contains a chapter dedicated to maternal health. Included in the new code are cases in which abortion is allowed: 1) when 2 specialists affirm that the pregnancy or childbirth constitutes a risk to the mother's health or life; 2) if the medical history of the parents and 2 doctors confirm the likelihood of the baby being born seriously disabled or deformed; or 3) if the mother's mental health is put in jeopardy by continuing the pregnancy. Despite the disapproval of church representatives, the legalization of abortion was unanimously approved by the Congress. The debate which surrounded the process was increased by a petition signed by more than 260 women decrying the lack of input that women had in the decision-making process. Women's action groups have been trying to widen the context in which the political discussion is taking place to stress the importance of viewing abortion from a reproductive rights perspective. The women's groups wish to prevent a situation in which the discussion surrounding the issue will be limited to legislators and church leaders. The women have pointed out that women should make the decisions about their lives and their bodies. In the meantime, the president of the Congress predicts that illegal abortion will continue in the Dominican Republic regardless of the current provisions for legal abortion. PMID:12286344

    Unsafe abortion is prevalent in many developing countries, mostly in sub-Saharan Africa, Latin America and South and Southeast Asia, where abortion laws are more restrictive, the unmet need for contraception high and the status of women in society low. The main interventions for reducing the prevalence of unsafe abortion are known: better and more widely available family planning services, comprehensive sex education, improved access to safe abortion and high-quality post-abortion care, including contraceptive counselling and on-site services. Although these proposals have been included in statements and recommendations drawn up at several international conferences and adopted by the vast majority of nations, they have either been inadequately implemented or not implemented at all in the countries in which the need is greatest. A well-coordinated effort by both national and international organisations and agencies is required to put these recommendations into practice; however, the most important factor determining the success of such efforts is the commitment of governments towards preventing unsafe abortion and reducing its prevalence and consequences.

    The antiabortion groups and their lawyers have added a new weapon to their arsenal against physicians who perform abortions in the US: malpractice lawsuits. The nonprofit educational organization Life Dynamics generates material for personal injury lawyers and is participating in 80 cases. It has assembled 642 lawyers and 500 physicians in its abortion malpractice program. Life Dynamics calls for persons to support lawsuits to increase malpractice insurance rates of abortionists, thereby forcing them out of business. Its 2-day 1994 seminar in Texas addressed abortion injuries, an alleged link between abortion and breast cancer, and abortion as a likely source of post-traumatic stress disorder. A lawyer and general counsel of the Arizona Right-to-Life has filed two lawsuits against a Phoenix physician who performs abortion. The trial judge dismissed both cases and fined the lawyer for frivolous lawsuits. An appeal overturned the fines. The lawyer has three more lawsuits on the docket. The physician had complained to the Arizona Bar Association about the lawyer. Even though the physician's insurance company did not pay any claims, its underwriters deemed him an actuarial risk, thereby making him essentially uninsurable. Local medical associations have failed to take a position on the lawyer's legal misconduct because they do not want to alienate some members. The Planned Parenthood Federation of America agreed that the lawsuits brought against the Phoenix physician were fraudulent and that they do not aim to protect women but to revoke their right to choose.

  8. The problems of therapeutic abortion and infanticide.

    Medical professionals need to revaluate current ethical standards which permit the killing of a normal fetus but require the use of heroic efforts to save the life of a severely deformed or mentally handicapped child once that child is born. The ethical issues involved in both abortion and infanticide are similar. Direct objections to both of these practices refer to the person killed and indirect objections refer to the side effects experienced by the family and society. Direct objections are irrelevant in abortion since the fetus is not aware that it is being killed and are also irrelevant in infanticide until the child is old enough to become aware of death. Indirect objections to abortion include: 1) guilt experienced by the mother and the abortion provider; 2) decline in maternal feeling in the society as a whole; and 3) the use of medical personnel and facilitates to provide unnecessary services. Advantages associated with abortion are that it: 1) reduces the number of unwanted children; 2) reduces the number of abnormal children; and 3) provides a safe and inexpensive form of contraception. Indirect objects to to infanticide are similar to those noted for abortion. The advantage of infanticide is that it avoids the on-going distress of parents who must live with and support a severe handicapped child. PMID:657265

    It is common to think of scientific research and the knowledge it generates as neutral and value free. Indeed, the scientific method is designed to produce "objective" data. However, there are always values built into science, as historians of science and technology have shown over and over. The relevant question is not how to rid science of values but, instead, to ask which values and whose values belong? Currently, antiabortion values consistently determine US research policy. Abortion research is declared illegitimate in covert and overt ways, at the level of individual researchers and research policy broadly. Most importantly, federal policy impedes conduct of both basic and clinical research in abortion. However, it is not just research in abortion that is deemed "illegitimate;" research in infertility and in vitro fertilization is as well. Federal funding of any reproductive health research agenda that would pose more than minimal risk to a fetus or embryo is banned. This leaves unanswered scientific questions about abortion, infertility, miscarriage and contraception among other areas. Since moral ground is occupied not just by abortion opponents but also by people who support abortion rights, there is at the very least a competing moral claim to consider changing federal research funding policy. Women and families deserve access to knowledge across the spectrum of reproductive health issues, whether they seek to end or start a pregnancy. Thus, research funding is an issue of reproductive justice. PMID:23815965

    PubMed

    1981-05-01

    A study conducted in 1979 on 3800 Paraguayan women in fertile age revealed that 30.7% had abortions, that the frequency of abortion was 14.5/100 pregnancies, and that the highest incidence was to be found among unmarried women or among those living in consensual unions. 35% of women seeking abortion had more than elementary school education, as compared to 26% of illiterate women, 36.4% lived in urban areas, 45% lived in consensual union, as opposed to 27% who were married, 40% had parity between 4 and 7, and about 40% were aged between 30-44. Another study conducted in 1971 in 5 Paraguayan cities showed that among women aged 15-49 only 26.7% used an effective method of contraception, 22.1% used an ineffective one, and 51.2% used no contraception. In the 1st group of women the number of live births and of induced abortions was smaller than in the other groups, with about 2356 births averted and 2834 fetal deaths averted. It appears that effective contraception prevents induced abortion rather than decreasing natality; the same study shows that with an observed fertility rate of 114.5/1000 without contraception, and a fertility rate of 113.8/1000 with contraception the difference is only -0.6%, while with an observed rate of induced abortion of 18.5/1000 without contraception, and a rate of 16.7/1000 with contraception, the variation is -9.7%.

    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.

    Hoping to provide women other choice besides abortion as a way to regulate fertility, 220 experts from 27 mostly European countries met in Tbilisi, Georgia, USSR to discuss ways of increasing access to modern contraceptives. Held last October, the conference was sponsored by the United Nations Population Fund (UNFPA), the World Health Organization European Regional Office (WHO/EURO), the International Planned Parenthood Federation/Europe, and the Zhordania Institute of Human Reproduction, Tbilisi. The meeting produced the Tbilisi Declaration, which -- among other things -- recognizes that unwanted pregnancies and unsafe abortions pose a serious health and social problem. Criminalization, the experts agreed, does little to reduce the number of abortions, and only increases the number of unsafe operations. The Tbilisi Declaration also affirms women's right to decide freely on the number and spacing of children, their right to reproductive health, their right to self-determination in their sexual and reproductive lives, and the right of every child to be a wanted child. The participants addressed the high incidents of abortion in some European countries -- particularly the Soviet Union. With the highest rate of abortion in Europe, the Soviet Union recorded 6 million legal abortions in 1988, and estimates that another 6 million were performed illegally. Nonetheless, perestroika has begun to facilitate access to contraceptives. Participants also discussed new methods of early pregnancy termination, RU486 and menstrual regulation procedures (MR), neither of which is readily available. Increasing access to these methods would help reduce suffering and unnecessary deaths. PMID:12283600

    Kaposi's sarcoma-associated herpesvirus (KSHV) is an oncogenic herpesvirus associated with multiple AIDS-related malignancies. Like other herpesviruses, KSHV has a biphasic life cycle and both the lytic and latent phases are required for tumorigenesis. Evidence suggests that KSHV lytic replication can cause genome instability in KSHV-infected cells, although no mechanism has thus far been described. A surprising link has recently been suggested between mRNA export, genome instability and cancer development. Notably, aberrations in the cellular transcription and export complex (hTREX) proteins have been identified in high-grade tumours and these defects contribute to genome instability. We have previously shown that the lytically expressed KSHV ORF57 protein interacts with the complete hTREX complex; therefore, we investigated the possible intriguing link between ORF57, hTREX and KSHV-induced genome instability. Herein, we show that lytically active KSHV infected cells induce a DNA damage response and, importantly, we demonstrate directly that this is due to DNA strand breaks. Furthermore, we show that sequestration of the hTREX complex by the KSHV ORF57 protein leads to this double strand break response and significant DNA damage. Moreover, we describe a novel mechanism showing that the genetic instability observed is a consequence of R-loop formation. Importantly, the link between hTREX sequestration and DNA damage may be a common feature in herpesvirus infection, as a similar phenotype was observed with the herpes simplex virus 1 (HSV-1) ICP27 protein. Our data provide a model of R-loop induced DNA damage in KSHV infected cells and describes a novel system for studying genome instability caused by aberrant hTREX. PMID:24788796

    Abortion rates rose following the expanded legalization of abortion by the Supreme Court decision in Roe v. Wade. As a result, the impact of the restriction on Federal funding of abortions under the Hyde Amendment in 1977 was not clear. However, abortion rates had plateaued by 1985, when State funding of Medicaid abortions was restricted in Colorado, North Carolina, and Pennsylvania. Analysis of statewide data from the three States indicated that following restrictions on State funding of abortions, the proportion of reported pregnancies resulting in births, rather than in abortions, increased in all three States. In 1985, the first year of State restrictions on the use of public funds for abortion, Colorado, North Carolina, and Pennsylvania recorded 1.9 to 2.4 percent increases in the proportion of reported pregnancies resulting in live births, after years of declining rates. With adjustments for underreporting of abortion, there was an overall 1.2 percent rise in the proportion of pregnancies resulting in live births in those States. Nationally the proportion rose only 0.4 percent. By 1987, the three States had experienced increases above 1984 levels of 1.6 to 5.9 percent in the proportion of reported pregnancies resulting in live births. The experiences of the three States can be used in projecting an expected increase in the proportions of reported pregnancies resulting in live births, rather than in abortions, for similar States. A projection for California, for example, showed that an increase could be expected in the first year of restrictions on the use of public funds for abortion of at least 4,000 births, which could be expected largely to affect women of low income.

    Background Primary-HIV-1-infection in newborns that occurs under antiretroviral prophylaxis that is a high risk of drug-resistance acquisition. We examine the frequency and the mechanisms of resistance acquisition at the time of infection in newborns. Patients and Methods We studied HIV-1-infected infants born between 01 January 1997 and 31 December 2004 and enrolled in the ANRS-EPF cohort. HIV-1-RNA and HIV-1-DNA samples obtained perinatally from the newborn and mother were subjected to population-based and clonal analyses of drug resistance. If positive, serial samples were obtained from the child for resistance testing. Results Ninety-two HIV-1-infected infants were born during the study period. Samples were obtained from 32 mother-child pairs and from another 28 newborns. Drug resistance was detected in 12 newborns (20%): drug resistance to nucleoside reverse transcriptase inhibitors was seen in 10 cases, non-nucleoside reverse transcriptase inhibitors in two cases, and protease inhibitors in one case. For 9 children, the detection of the same resistance mutations in mothers' samples (6 among 10 available) and in newborn lymphocytes (6/8) suggests that the newborn was initially infected by a drug-resistant strain. Resistance variants were either transmitted from mother-to-child or selected during subsequent temporal exposure under suboptimal perinatal prophylaxis. Follow-up studies of the infants showed that the resistance pattern remained stable over time, regardless of antiretroviral therapy, suggesting the early cellular archiving of resistant viruses. The absence of resistance in the mother of the other three children (3/10) and neonatal lymphocytes (2/8) suggests that the newborns were infected by a wild-type strain without long-term persistence of resistance when suboptimal prophylaxis was stopped. Conclusion This study confirms the importance of early resistance genotyping of HIV-1-infected newborns. In most cases (75%), drug resistance was archived in

    Imaging is useful in the diagnosis and management of infections of the central nervous system. Typically, imaging findings at the outset of the disease are subtle and nonspecific, but they often evolve to more definite imaging patterns in a few days, with less rapidity than for stroke but faster than for neoplastic lesions. This timing is similar to that of noninfectious inflammatory brain disease, such as multiple sclerosis. Fortunately, imaging patterns help to distinguish the two kinds of processes. Other than for sarcoidosis, the meninges are seldom involved in noninfectious inflammation; in contrast, many infectious processes involve the meninges, which then enhance with contrast on computed tomography (CT) or magnetic resonance imaging (MRI). However, brain infection causes a vast array of imaging patterns. Although CT is useful when hemorrhage or calcification is suspected or bony detail needs to be determined, MRI is the imaging modality of choice in the investigation of intracranial infections. Imaging sequences such as diffusion-weighted imaging help in accurately depicting the location and characterizing pyogenic infections and are particularly useful in differentiating bacterial infections from other etiologies. Susceptibility-weighted imaging is extremely useful for the detection of hemorrhage. Although MR spectroscopy findings can frequently be nonspecific, certain conditions such as bacterial abscesses show a relatively specific spectral pattern and are useful in diagnosing and constituting immediate therapy. In this chapter we review first the imaging patterns associated with involvement of various brain structures, such as the epidural and subdural spaces, the meninges, the brain parenchyma, and the ventricles. Involvement of these regions is illustrated with bacterial infections. Next we illustrate the patterns associated with viral and prion diseases, followed by mycobacterial and fungal infections, to conclude with a review of imaging findings

    Burkholderia pathogenicity relies on protein virulence factors to control and promote bacterial internalization, survival, and replication within eukaryotic host cells. We recently used yeast two-hybrid (Y2H) screening to identify a small set of novel Burkholderia proteins that were shown to attenuate disease progression in an aerosol infection animal model using the virulent Burkholderia mallei ATCC 23344 strain. Here, we performed an extended analysis of primarily nine B. mallei virulence factors and their interactions with human proteins to map out how the bacteria can influence and alter host processes and pathways. Specifically, we employed topological analyses to assess the connectivity patterns of targeted host proteins, identify modules of pathogen-interacting host proteins linked to processes promoting infectivity, and evaluate the effect of crosstalk among the identified host protein modules. Overall, our analysis showed that the targeted host proteins generally had a large number of interacting partners and interacted with other host proteins that were also targeted by B. mallei proteins. We also introduced a novel Host-Pathogen Interaction Alignment (HPIA) algorithm and used it to explore similarities between host-pathogen interactions of B. mallei, Yersinia pestis, and Salmonella enterica. We inferred putative roles of B. mallei proteins based on the roles of their aligned Y. pestis and S. enterica partners and showed that up to 73% of the predicted roles matched existing annotations. A key insight into Burkholderia pathogenicity derived from these analyses of Y2H host-pathogen interactions is the identification of eukaryotic-specific targeted cellular mechanisms, including the ubiquitination degradation system and the use of the focal adhesion pathway as a fulcrum for transmitting mechanical forces and regulatory signals. This provides the mechanisms to modulate and adapt the host-cell environment for the successful establishment of host infections

    Since the legalization of abortion in Israel in the late 1970s, only aggregate information on legal abortions has been available. A brief history of the public debate and relevant legislation concerning induced abortions in Israel is presented in the first part of this report. The second part presents estimates of the extent of illegal abortions in Israel during the years 1980-83. These estimates were obtained through standardization based on data for selected countries where the abortion law is similar to or more liberal than that in Israel, the system of abortion registration is more reliable and detailed, and the prevailing contraceptive habits and attitudes of women are known. Estimates indicate that: a) the total number of abortions in Israel is about half that quoted by the media from nonscientific sources, and b) the annual number of illegal abortions constitutes between 25 and 30% of the estimated total number of abortions.

    This article discusses a clinical trial with the abortifacient agent ethacridine lactate as it was used for midtrimester abortion in Calcutta during the period January-July 1980. Results are then compared with intraamniotic hypertonic saline. 130 subjects were divided into 2 groups--Group 1 (60 women) were terminated with ethacridine lactate and group 2 (70 women) were terminated with saline. In cases where the patient complained of pain, analgesia was administered. In both groups, the largest concentration of women fell in the age groups 16-20 and 21-25. Similarly, single women were the largest representation in both groups although the saline group included more widows. Ethacridine lactate can be administered earlier in the 2nd trimester than saline. With it, expulsion occurred within 36 hours in 56.6% of the cases as compared with 22.9% in group 2. Both groups required the same amount of assistance with oxytocin. In group 1, there were only 3 cases (5%) of minor complications whereas in group 2, 19 cases (27.1%) developed complications. This alone strongly recommends ethacridine lactate as the preferred abortifacient. The success rate was 98%. Thus, ethacridine lactate appears to be a safe and effective agent for pregnancy termination during the 2nd trimester. PMID:7142727

    Abortion is a relatively frequent experience, yet public discourse about abortion is contentious and stigmatizing. Little literature is available on private conversations about abortion, which may be distinct from public discourse. We explored private discourse by documenting the nature of women's discussions about abortion with peers in a book club. We recruited thirteen women's book clubs in nine states. Participants (n = 119) read the book Choice: True Stories of Birth, Contraception, Infertility, Adoption, Single Parenthood, & Abortion, and participated in a book club meeting, which we audio-recorded and transcribed. Data collection occurred between April 2012 and April 2013. In contrast to public discourse of abortion, private discourse was nuanced and included disclosures of multiple kinds of experiences with abortion. Participants disclosed having abortions, considering abortion as an option for past or future pregnancies, and supporting others through an abortion. Distinguishing between public and private discourse enabled us to identify that an "abortion experience" could include personal decisions, hypothetical decisions, or connection with someone having an abortion. The book club atmosphere provided a rare opportunity for participants to explore their relationship to abortion. More research is needed to understand the role of private discourse in reducing abortion stigma. PMID:26086582

  3. Functional Mechanisms of Treg in the Context of HIV Infection and the Janus Face of Immune Suppression

    2016-01-01

    Regulatory T cells (Tregs) play an important role in infections, by modulating host immune responses and avoiding the overreactive immunity that in the case of human immunodeficiency virus (HIV) infection leads to a marked erosion and deregulation of the entire immune system. Therefore, the suppressive function of Treg in HIV-infected patients is critical because of their implication on preventing the immune hyperactivation, even though it could also have a detrimental effect by suppressing HIV-specific immune responses. In recent years, several studies have shown that HIV-1 can directly infect Treg, disturbing their phenotype and suppressive capacity via different mechanisms. These effects include Foxp3 and CD25 downregulation, and the impairment of suppressive capacity. This review describes the functional mechanisms of Treg to modulate immune activation during HIV infection, and how such control is no longer fine-tune orchestrated once Treg itself get infected. We will review the current knowledge about the HIV effects on the Treg cytokine expression, on pathways implying the participation of different ectoenzymes (i.e., CD39/CD73 axis), transcription factors (ICER), and lastly on cyclic adenosine monophosphate (cAMP), one of the keystones in Treg-suppressive function. To define which are the HIV effects upon these regulatory mechanisms is crucial not only for the comprehension of immune deregulation in HIV-infected patients but also for the correct understanding of the role of Tregs in HIV infection.

    M. Segers and G. Annas' (Hastings Center Report, August 1977) criticisms of the U.S. Supreme Court's recent abortion decisions are thought to be unpersuasive. Any sound argument against the Court's decision must avoid the conclusion that the government, either state or federal, is constitutionally required to finance any activity which is constitutionally protected if the person wishing to engage in the activity is unable to finance the activity. The argument given by Segers does not avoid this implausible conclusion. She contends that the lack of legislation providing for the public financing of elective abortions "plainly discriminates against a social class, since a right guaranteed to the rich is denied in practice to the poor." Annas' reasoning is considered better, for he implies that the failure publicly to finance elective abortion constitutes unconstitutional interference with the indigent woman's right to an abortion, citing the Doe v. Bolton ruling which struck down the Georgia law requiring the concurrence of 2 physicians before an abortion lawfully could be performed. Of the 3 articles in the Report for August, it is felt that Annas' comes closest to recognizing the true nature of the constitutional issue raised by these abortion cases, but even his argument eventually moves into viewing the issue as one of "the rich" vs. "the poor." Possibly there is an issue here of social justice which can be viewed in terms of "the rich" vs. "the poor," and the demands of justice might categorically require the financing of all abortions for the indigent so that they can exercise this important legal right. However, the Constitution is not a document that incorporates all of the principles of social justice and does not impose such a requirement. PMID:649373

    The issue of conscientious objection in Spain has been used by pro-choice groups against objecting health personnel as one of the obstacles to the implementation of the abortion law, a misnomer. At present objection is massive in the public sector; 95% of abortions are carried out in private clinics with highly lucrative returns; abortion tourism has decreased; and false objection has proliferated in the public sector when the objector performs abortions in the private sector for high fees. The legal framework for conscientious objection is absent in Spain. Neither Article 417 of the Penal Code depenalizing abortion, nor the Ministerial Decree of July 31, 1985, nor the Royal Decree of November 21, 1986 recognize such a concept. However, the ruling of the Constitutional Court on April 11, 1985 confirmed that such objection can be exercised with independence. Some authors refer to the applicability of Law No. 48 of December 16, 1984 that regulates conscientious objection in military service to health personnel. The future law concerning the fundamental right of ideological and religious liberty embodied in Article 16.1 of the Constitution has to be revised. A draft bill was submitted in the Congress or Representatives concerning this issue on May 3, 1985 that recognizes the right of medical personnel to object to abortion without career repercussions. Another draft bill was introduced on April 17, 1985 that would allow the nonparticipation of medical personnel in the interruption of pregnancy, however, they would be prohibited from practicing such in the private hospitals. Neither of these proposed bills became law. Professional groups either object unequivocally, or do not object at all, or object on an ethical level but do not object to therapeutic abortion. The resolution of this issue has to be by consensus and not by imposition. PMID:1565971

    Objectives: To determine if there is a biological mechanism that explains the association between HIV disease progression and increased mortality with low circulating vitamin D levels; specifically, to determine if restoring vitamin D levels induced T-cell functional changes important for antiviral immunity. Design: This was a pilot, open-label, three-arm prospective phase 1 study. Methods: We recruited 28 patients with low plasma vitamin D (<50 nmol/l 25-hydroxyvitamin D3), comprising 17 HIV+ patients (11 on HAART, six treatment-naive) and 11 healthy controls, who received a single dose of 200 000 IU oral cholecalciferol. Advanced T-cell flow cytometry methods measured CD4+ T-cell function associated with viral control in blood samples at baseline and 1-month after vitamin D supplementation. Results: One month of vitamin D supplementation restored plasma levels to sufficiency (>75 nmol/l) in 27 of 28 patients, with no safety issues. The most striking change was in HIV+ HAART+ patients, where increased frequencies of antigen-specific T cells expressing macrophage inflammatory protein (MIP)-1β – an important anti-HIV blocking chemokine – were observed, with a concomitant increase in plasma MIP-1β, both of which correlated significantly with vitamin D levels. In addition, plasma cathelicidin – a vitamin D response gene with broad antimicrobial activity – was enhanced. Conclusion: Vitamin D supplementation modulates disease-relevant T-cell functions in HIV-infected patients, and may represent a useful adjunct to HAART therapy. PMID:25870995

    Stenotrophomonas maltophilia is a Gram-negative, biofilm-forming bacterium. Although generally regarded as an organism of low virulence, S. maltophilia is an emerging multi-drug resistant opportunistic pathogen in hospital and community settings, especially among immunocompromised hosts. Risk factors associated with S. maltophilia infection include underlying malignancy, cystic fibrosis, corticosteroid or immunosuppressant therapy, the presence of an indwelling central venous catheter and exposure to broad spectrum antibiotics. In this review, we provide a synthesis of information on current global trends in S. maltophilia pathogenicity as well as updated information on the molecular mechanisms contributing to its resistance to an array of antimicrobial agents. The prevalence of S. maltophilia infection in the general population increased from 0.8–1.4% during 1997–2003 to 1.3–1.68% during 2007–2012. The most important molecular mechanisms contributing to its resistance to antibiotics include β-lactamase production, the expression of Qnr genes, and the presence of class 1 integrons and efflux pumps. Trimethoprim/sulfamethoxazole (TMP/SMX) is the antimicrobial drug of choice. Although a few studies have reported increased resistance to TMP/SMX, the majority of studies worldwide show that S. maltophilia continues to be highly susceptible. Drugs with historically good susceptibility results include ceftazidime, ticarcillin-clavulanate, and fluoroquinolones; however, a number of studies show an alarming trend in resistance to those agents. Tetracyclines such as tigecycline, minocycline, and doxycycline are also effective agents and consistently display good activity against S. maltophilia in various geographic regions and across different time periods. Combination therapies, novel agents, and aerosolized forms of antimicrobial drugs are currently being tested for their ability to treat infections caused by this multi-drug resistant organism.

    Clostridium difficile infection (CDI) represents the most prevalent cause of antibiotic-associated gastrointestinal infections in health care facilities in the developed world. Disease symptoms are caused by the two homologous exotoxins, TcdA and TcdB. Standard therapy for CDI involves administration of antibiotics that are associated with a high rate of disease recurrence, highlighting the need for novel treatment paradigms that target the toxins rather than the organism itself. A combination of human monoclonal antibodies, actoxumab and bezlotoxumab, directed against TcdA and TcdB, respectively, has been shown to decrease the rate of recurrence in patients treated with standard-of-care antibiotics. However, the exact mechanism of antibody-mediated protection is poorly understood. In this study, we show that the antitoxin antibodies are protective in multiple murine models of CDI, including systemic and local (gut) toxin challenge models, as well as primary and recurrent models of infection in mice. Systemically administered actoxumab-bezlotoxumab prevents both the damage to the gut wall and the inflammatory response, which are associated with C. difficile in these models, including in mice challenged with a strain of the hypervirulent ribotype 027. Furthermore, mutant antibodies (N297Q) that do not bind to Fcγ receptors provide a level of protection similar to that of wild-type antibodies, demonstrating that the mechanism of protection is through direct neutralization of the toxins and does not involve host effector functions. These data provide a mechanistic basis for the prevention of recurrent disease observed in CDI patients in clinical trials. PMID:25486992

    According to the World Health Organization, post-traumatic mortality rates are still very high and show an increasing tendency. Disorders of innate immune response that may increase the risk of serious complications play a key role in the immunological system response to trauma and infection. The mechanism of these disorders is multifactorial and is still poorly understood. The changing concepts of systemic inflammatory response syndrome (SIRS) and compensatory anti-inflammatory response syndrome (CARS) early inflammatory response, presented in this work, have been extended to genetic studies. Overexpression of genes and increased production of immune response mediators are among the main causes of multiple organ dysfunction syndrome (MODS). Changes in gene expression detected early after injury precede the occurrence of subsequent complications with a typical clinical picture. Rapid depletion of energy resources leads to immunosuppression and persistent inflammation and immune suppression catabolism syndrome (PICS). Early diagnosis of immune disorders and appropriate nutritional therapy can significantly reduce the incidence of complications, length of hospital stay, and mortality. The study presents the development of knowledge and current views explaining the mechanisms of the immune response to trauma and infection. PMID:26557036

    The potent protective immunity against malaria induced by immunization of mice and humans with radiation-attenuated Plasmodium spp. sporozoites is thought to be mediated primarily by T-cell responses directed against infected hepatocytes. This has led to considerable efforts to develop subunit vaccines that duplicate this protective immunity, but a universally effective vaccine is still not available and in vitro correlates of protective immunity have not been established. Contributing to this delay has been a lack of understanding of the mechanisms responsible for the protection. There are now data indicating that CD8+ T cells, CD4+ T cells, cytokines, and nitric oxide can all mediate the elimination of infected hepatocytes in vitro and in vivo. By dissecting the protection induced by immunization with irradiated sporozoite, DNA and synthetic peptide-adjuvant vaccines, we have demonstrated that different T-cell-dependent immune responses mediate protective immunity in the same inbred strain of mouse, depending on the method of immunization. Furthermore, the mechanism of protection induced by a single method of immunization may vary among different strains of mice. These data have important implications for the development of pre-erythrocytic-stage vaccines designed to protect a heterogeneous human population, and of assays that predict protective immunity.

    Of 881 Chinese handwritten volumes with medical texts of the 17th through mid-20th century held by Staatsbibliothek zu Berlin and Ethnologisches Museum Berlin-Dahlem, 48 volumes include prescriptions for induced abortion. A comparison shows that these records are significantly different from references to abortion in Chinese printed medical texts of pre-modern times. For example, the percentage of recipes recommended for artificial abortions in handwritten texts is significantly higher than those in printed medical books. Authors of handwritten texts used 25 terms to designate artificial abortion, with the term da tai [see text], lit.: "to strike the fetus", occurring most frequently. Its meaning is well defined, in contrast to other terms used, such as duo tai [see text], lit: "to make a fetus fall", xia tai [see text], lit. "to bring a fetus down", und duan chan [see text], lit., to interrupt birthing", which is mostly used to indicate a temporary or permanent sterilization. Pre-modern Chinese medicine has not generally abstained from inducing abortions; physicians showed a differentiating attitude. While abortions were descibed as "things a [physician with an attitude of] humaneness will not do", in case a pregnancy was seen as too risky for a woman she was offered medication to terminate this pregnancy. The commercial application of abortifacients has been recorded in China since ancient times. A request for such services has continued over time for various reasons, including so-called illegitimate pregnancies, and those by nuns, widows and prostitutes. In general, recipes to induce abortions documented in printed medical literature have mild effects and are to be ingested orally. In comparison, those recommended in handwritten texts are rather toxic. Possibly to minimize the negative side-effects of such medication, practitioners of folk medicine developed mechanical devices to perform "external", i.e., vaginal approaches. PMID:24195336

  16. Abortion attitudes among nurses and social workers.

    1974-05-01

    A survey of attitudes toward abortion was conducted among nurses and social workers in Tennessee. It was found that, even when relevant background characteristics were similar, social workers were more liberal toward abortion than nurses. It is suggested that the difference may result from differences in goals and types of client contact within the 2 professions. Because social workers aim at helping clients "cope" with many problematic situations and nurses aim at preserving patients' health, social work involves contact with a greater part of clients' lives than nursing. Nurses tend to view abortion as a medical procedure while social workers may consider it an appropriate procedure for various social, economic, and psychological reasons. Social workers see clients in normal life situations but nurses see them under specialized medical conditions in clinics or hospitals. It is more likely that social workers would understand the benefit an abortion could provide to a client. It is speculated that, in the future, social workers will refer poor clients to clinics or hospitals for abortions they feel are necessary and nurses will discourage or turn away many of these clients.

    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. PMID:11424252

    OBJECTIVE: To describe women's experiences with expectant management of spontaneous abortions. DESIGN: Descriptive survey using questionnaires with fixed-choice and open-ended questions. The latter were analyzed for themes, using qualitative methods. SETTING: Urban and suburban private primary care family practices. PARTICIPANTS: A convenience sample of family practice patients (59 of 80 eligible) pregnant for less than 12 weeks who had spontaneous abortions without surgery. Response rate was 84.7%; 50 questionnaires were received from the 59 women. METHOD: Women were asked about their physical experiences, including amount of pain and bleeding; emotional effects; their satisfaction with medical care; and their suggestions for improving care. MAIN FINDINGS: The mean worst pain experienced during a spontaneous abortion on an 11-point scale was 5.9. Bleeding varied, but was often very heavy. Satisfaction rate was 92.9% with family physician care and 84.6% with hospital care. Women described the emotional effect of "natural" spontaneous abortions and made recommendations for improving care. CONCLUSIONS: A better understanding of the physical and emotional experiences of the women in this study might help physicians better prepare and support patients coping with expectant management of spontaneous abortions.

    Because the number of physicians available to perform abortions in the US is dwindling, certified nurse-midwives, nurse practitioners, and physician assistants should be trained and permitted to perform abortions. Roadblocks to this change are the fact that the Supreme Court would likely allow states to prevent mid-level practitioners from performing abortions in the name of protecting the health of the mother. Also, existing statutes would probably not be interpreted by courts to allow mid-level practitioners to perform abortions. However, physician assistants have been performing abortions in Vermont since 1975, and a 1981-82 comparative study affirmed that physician assistants are well-equipped to perform abortions (of 2458 procedures, the complication rate/1000 was 27.4 for physician assistants and 30.8 for physicians). However, controversy surrounds the provision of abortion by these physician assistants in Vermont, since the relevant statute suggests that abortion is illegal unless performed by a physician. However, the statute has not been changed since Roe vs. Wade and is likely unconstitutional. Court cases in Missouri and Tennessee suggest that courts may be willing to include abortion within the scope of progressive nursing practice acts, but a recent similar case in Massachusetts resulted in a narrow interpretation of nursing practice statutes. Because the definition of professional nursing varies with each state statute, it will be a formidable task to convince every jurisdiction to include abortion as a permissible mid-level practice. Even in Vermont, the nursing practice statute defines in an exclusive list what services the professional nurse may perform (whereas the physician assistant regulations limit their scope of practice only to that delegated by a supervising physician). States could, of course, pass statutes which include abortion as a permissible practice for the mid-level practitioner. However, specific legislation would provide a clear

    This paper analyzes the illegal trade in misoprostol, the medication predominantly used for abortion in Brazil. The study analyzed ten cases that came to the attention of the Public Prosecution Service for the Federal District between 2004 and 2010. The cases were organized into three categories: 1. women's stories; 2. profile of the vendors; 3. maternal mortality cases. The research was reviewed by an ethics committee. The main outcomes were: 1. young women in steady relationships use misoprostol in the home or with the assistance of drug vendors. Of the seven women indicted, three were reported on arrival at the public hospital to finalize abortion; 2. the drug vendors work at the community drugstore and are local agents for the sale of misoprostol. They instruct women on how to use the drug and how to prevent infections, but refuse to provide them with care in case of emergency. Traffickers operate via the internet and have a larger inventory of drugs; 3. there were two cases of maternal mortality due to the combination of high risk methods, such as a vaginal probe and misoprostol. The main causes for maternal mortality are the delay in seeking medical care, as the women fear criminal prosecution, and the combined use of misoprostol with high risk methods. PMID:22872341

  1. Application of Fault Management Theory to the Quantitative Selection of a Launch Vehicle Abort Trigger Suite

    The theory of System Health Management (SHM) and of its operational subset Fault Management (FM) states that FM is implemented as a "meta" control loop, known as an FM Control Loop (FMCL). The FMCL detects that all or part of a system is now failed, or in the future will fail (that is, cannot be controlled within acceptable limits to achieve its objectives), and takes a control action (a response) to return the system to a controllable state. In terms of control theory, the effectiveness of each FMCL is estimated based on its ability to correctly estimate the system state, and on the speed of its response to the current or impending failure effects. This paper describes how this theory has been successfully applied on the National Aeronautics and Space Administration's (NASA) Space Launch System (SLS) Program to quantitatively estimate the effectiveness of proposed abort triggers so as to select the most effective suite to protect the astronauts from catastrophic failure of the SLS. The premise behind this process is to be able to quantitatively provide the value versus risk trade-off for any given abort trigger, allowing decision makers to make more informed decisions. All current and planned crewed launch vehicles have some form of vehicle health management system integrated with an emergency launch abort system to ensure crew safety. While the design can vary, the underlying principle is the same: detect imminent catastrophic vehicle failure, initiate launch abort, and extract the crew to safety. Abort triggers are the detection mechanisms that identify that a catastrophic launch vehicle failure is occurring or is imminent and cause the initiation of a notification to the crew vehicle that the escape system must be activated. While ensuring that the abort triggers provide this function, designers must also ensure that the abort triggers do not signal that a catastrophic failure is imminent when in fact the launch vehicle can successfully achieve orbit. That is

    Spontaneous abortion is the loss of a fetus before the 20th week of pregnancy, when occurring naturally without any surgical or pharmaceutical intervention. On the other hand, Listeria monocytogenes, as one of the foodborne pathogens, is a causative agent of listeriosis. The transfer of L. monocytogenes in pregnant women occurs as self-limited flu-like symptoms which may result in abortion, stillbirth or premature birth of infected infants. The purpose of this study was the identification of Listeria monocytogenes risk factors in women with spontaneous abortion admitted to Tehran Province health care centers in 2015. In this cross-sectional study, 317 women were examined for L. monocytogenes using Polymerase Chain Reaction (PCR) and the related risk factors. Two questionnaires on "L. monocytogenes Probable Risk Factors" and "Socio Economic Factors" were completed. Out of 317 samples of vaginal swabs, 54 (17%) isolates of L. monocytogenes were identified. In addition significant differences in terms of age of mother and her husband, mother and the husband's level of education , house prices, place of residence, gestational age of first abortion, gestational age of current abortion, gestational age of second abortion, consumption of unpasteurized dairy products, consumption of feta and soft cheese, consumption of smoked see food products, consumption of processed meat products and half-cooked meat products, consumption of ready-to-eat vegetables, history of contact with domestic animals three month before pregnancy and during pregnancy and consumption of smoked meat products during pregnancy were studied between two groups of patients positive and negative with L. monocytogens (P < 0.001). Based on the study, the detection of L. monocytogens risk factor during pregnancy as well as taking the issue into account while giving information and counseling in pregnancy can be vital to reduce the incidence of this bacterium and subsequently its side effects during

    Chlamydia trachomatis urogenital serovars replicate predominately in genital tract epithelium. This tissue tropism poses a unique challenge for host defense and vaccine development. Studies utilizing the Chlamydia muridarum mouse model have shown that CD4 T cells are critical for clearing genital tract infections. In vitro studies have shown that CD4 T cells terminate infection by up regulating epithelial iNOS transcription and nitric oxide production. However, this mechanism is not critical as iNOS-deficient mice clear infections normally. We recently showed that a subset of Chlamydia-specific CD4 T cell clones could terminate replication in epithelial cells using an iNOS-independent mechanism requiring T cell degranulation. We advance that work using microarrays to compare iNOS-dependent and iNOS-independent CD4 T cell clones. Plac8 was differentially expressed by clones having the iNOS-independent mechanism. Plac8-deficient mice had delayed clearance of infection, and Plac8-deficient mice treated with the iNOS-inhibitor N-monomethyl-L-arginine were largely unable to resolve genital tract infections over 8 weeks. These results demonstrate that there are two independent and redundant T cell mechanisms for clearing C. muridarum genital tract infections; one dependent on iNOS, the other dependent on Plac8. While T cells subsets are routinely defined by cytokine profiles, there may be important subdivisions by effector function, in this case CD4Plac8. PMID:22238459

    The French law legalizing abortion provided for a meeting between patient and social counselor prior to the intervention. Aim of this provision was to allow a women to see more clearly into herself, and to allow a social worker to help the patient make a personal and wise decision. Most women come to this encounter with feelings of guilt, anxiety, and depression; most of them want abortion because they know they can have one, and medical reasons for abortion are practacally nonexistant. The emotional situation of the couple, more than their socioeconomic condition, does have a great importance in making a final decision. A discussion can sometimes help, but the responsibility of the decision is with the women's alone. PMID:7401902

    The history of the past 16 years has borne out pro-life predictions that abortion would be the precursor of an even wider assault on helpless people. The unborn initially were the victim of choice because they were, in 1973, outside our customary line of moral vision. But as a dress rehearsal for a pattern of discretionary killing what was most significant about abortion was its explicit rejection of the Declaration of Independence's principle holding that our right to life is "inalienable." Abortion taught us that the lives of some are alienable and raised the question, why not the lives of others? Contrary to stereotype, the pro-life movement is a classic reform movement, inbued with a fierce belief in the inherent worth and equality of mankind. PMID:10294688

    Some psychopathological characteristics are frequently observed in women who have voluntarily aborted. However, some resistance currently remains to their recognition as a differentiated nosological category, known as Post-Abortion Syndrome (PAS). We tried to assign a diagnostic category to women with PAS by determining the extent by which they fulfilled the diagnostic criteria of international classifications. Criteria for Post-Traumatic Stress Disorder (PTSD) were met in the ten PAS cases studied. In addition, patients also showed other non-specific symptoms such as repeated and persistent dreams and nightmares related with the abortion, intense feelings of guilt and the "need to repair". PAS should be considered as an additional type of PTSD. It also has some specific characteristics that could help to understand the patient's life experience and to establish a psychotherapeutic intervention. PMID:15999304

    Doctors have been placed in an anomalous position by abortion laws which sanction the termination of a fetus while in a woman's womb, yet call it murder when a physician attempts to end the life of a fetus which has somehow survived such a procedure. This predicament, the doctors' dilemma, can be resolved by adopting a strategy which posits the right to ownership of one's own body for human beings. Such an approach will generate a consistent policy prescription, one that sanctions the right of all pregnant women to abortions, yet grants the fetus, after it becomes viable as a potentially independent person, a right to its own body. The doctors' dilemma is surmounted, then, by requiring that abortions of viable fetuses be performed in a manner that will produce a live delivery. Hence, infanticide and termination of viable fetuses are proscribed. PMID:490573

    There are significant variations in the legalisation, restrictions and legal abortion rates worldwide. This undoubtedly influences the provision and accessibility to abortion services. Although there have been changes to the laws in several countries over the last decade, this has not yet been translated into practice in the provision of safe abortion in these countries. In countries where abortions are permitted without restriction; the majority of abortions are carried out by trained practitioners in approved facilities. In contrast, in countries where restrictions are imposed, the majority of abortions performed are considered to be unsafe and therefore associated with significant morbidity and mortality. This article discusses the most recent data available regarding worldwide legal abortion rates, trends over the last ten years and issues related to specific regions which may influence the provision of safe abortion services in the future.

    Hepatitis C virus (HCV) infection frequently leads to chronic liver disease, liver cirrhosis and hepatocellular carcinoma (HCC). The molecular mechanisms by which HCV infection leads to chronic liver disease and HCC are not well understood. The infection cycle of HCV is initiated by the attachment and entry of virus particles into a hepatocyte. Replication of the HCV genome inside hepatocytes leads to accumulation of large amounts of viral proteins and RNA replication intermediates in the endoplasmic reticulum (ER), resulting in production of thousands of new virus particles. HCV-infected hepatocytes mount a substantial stress response. How the infected hepatocyte integrates the viral-induced stress response with chronic infection is unknown. The unfolded protein response (UPR), an ER-associated cellular transcriptional response, is activated in HCV infected hepatocytes. Over the past several years, research performed by a number of laboratories, including ours, has shown that HCV induced UPR robustly activates autophagy to sustain viral replication in the infected hepatocyte. Induction of the cellular autophagy response is required to improve survival of infected cells by inhibition of cellular apoptosis. The autophagy response also inhibits the cellular innate antiviral program that usually inhibits HCV replication. In this review, we discuss the physiological implications of the HCV-induced chronic ER-stress response in the liver disease progression. PMID:27223299

    Monocyte chemoattractant protein-1 (MCP-1/CCL2)-mediated migration of monocytes is essential for immunological surveillance of tissues. During chikungunya virus (CHIKV) infection however, excessive production of MCP-1 has been linked to disease pathogenesis. High MCP-1 serum levels are detected during the viremic phase of CHIKV infection and correlate with the virus titre. In vitro CHIKV infection was also shown to stimulate MCP-1 production in whole blood; yet the role and the mechanism of MCP-1 production upon infection of human peripheral blood mononuclear cells remain unknown. Here we found that active CHIKV infection stimulated production of MCP-1 in monocytes. Importantly however, we found that communication with other leukocytes is crucial to yield MCP-1 by monocytes upon CHIKV infection. Indeed, blocking interferon-α/β receptor or the JAK1/JAK2 signalling downstream of the receptor abolished CHIKV-mediated MCP-1 production. Additionally, we show that despite the apparent correlation between IFN type I, CHIKV replication and MCP-1, modulating the levels of the chemokine did not influence CHIKV infection. In summary, our data disclose the complexity of MCP-1 regulation upon CHIKV infection and point to a crucial role of IFNβ in the chemokine secretion. We propose that balance between these soluble factors is imperative for an appropriate host response to CHIKV infection. PMID:27558873

    A retrospective study of midtrimester abortions using the intraamniotic instillation of hypertonic saline solution was conducted. All 62 cases admitted to the Ramathibodi Hospital in Bangkok, Thailand for midtrimester abortion in 1980 were terminated by intraamniotic hypertonic saline instillation. The pregnancies were unwanted in 32 (51.6%) of the cases because of family problems, poor socioeconomic status, and deteriorated psychological health. 15 cases (24.2%) were preganancy from rape; 9 (14.5%) had rubella infection during the 1st trimester; and 3 cases (4.8%) were mentally retarded. There was 1 case of renal staghorn calculi post nephrostomy, 1 of multiparity with history of hemophilia in the family, and 1 of failed IUD contraception. The women were between 16-25 years of age in 39 cases, aged 15 or under in 4 cases (6.5%), and over age 35 in 4 cases. In 49 cases (79%) abortion was performed during 16-20 weeks gestation, in 12 cases (19.1%) at 21-24 weeks, and in 1 case at 25 weeks of gestation. The time interval from hypertonic saline instillation to abortion was analyzed in order to evaluate the effect of parity, amount of amniotic fluid withdrawn, and oxytocin augmentation. The mean instillation to abortion time (I-A) was 30.19 +or- 11.25 hours. There were 3 cases which did not receive oxytocin and who spontaneously aborted within 24 hours. Among cases which received oxytocin augmentation, there were 9 who received oxytocin immediately after instillation and 50 who received it 18-24 hours later. The I-A time was 31.22 +or- 11.63 hours in the group that received oxytocin immediately and 31.09 +or- 10.68 in the group receiving it later. There was no statistical difference between the 2 groups. Among the 50 cases which received oxytocin augmentation 18-24 hours later, there was no statistical difference between groups of nulliparity and multiparity. There were 46 cases in which the amount of amniotic fluid withdrawn was noted. In the group in which more than

    In most Latin American countries, abortion is not illegal if there is a risk to the life or health of the woman. This article discusses the process of expanding the interpretation of this "health exception" to mean that even the possibility of harm to health should make an abortion legal--which then becomes a mechanism for expanding women's right of access to safe abortion services. The article reports on an assessment of the impact of disseminating information on this interpretation of risk to health in Latin America, and how a regional process of debate and training of health service providers in 2009-10 has influenced the views and practice of health professionals in Argentina, Colombia, Mexico and Peru. The training included human rights arguments for applying the health exception in a comprehensive manner. All the respondents recognized the importance of interpreting risk to health as far more than the risk of death. Data from two clinics in Colombia also show an important increase in the number of women who had a legal abortion following this training. Dissemination of information and training on the health exception must continue--to protect women's right to health, reduce mortality and morbidity among those with unwanted pregnancies and encourage timely access to safe abortion services.

  18. Catholic options in the abortion debate.

    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. PMID:12178838

  19. Portugal takes step back on abortion legalization.

    1998-07-01

    According to international press reports, a law that would have allowed Portuguese women abortions through the 10th week of pregnancy and into the 16th week if their physical or mental health was at risk has been rescinded after a referendum to determine the statute's future was voided because of low voter turnout. Passed in February, the law was a liberalization of Portugal's strict anti-abortion laws, which ban all abortions except for narrowly defined medical reasons or in the case of rape (and those are permitted only until the 12th week of pregnancy). Because the issue is such a controversial one, politicians had turned to a national referendum asking Portuguese voters to overturn or ratify the new law. The referendum was the first in the country since the end of its right-wing dictatorship in 1974, and 50% participation was required. Only 31.5% of the country's 8.5 million eligible voters went to the polls on June 28. Of those voting, 50.9% voted against the liberalized new legislation. Sunny weather and World Cup soccer matches were both pointed to as reasons for the low turnout. Officials estimate there are some 20,000 illegal abortions annually in Portugal. Abortion-rights activists in the mostly Roman-Catholic country say hospitals see roughly 10,000 women a year suffering from complications from illegal abortions, and that at least 800 women die each year from the procedure. In the next day's Diario de Noticias, a daily paper in Portugal, the entire front page was filled with a giant question mark. "What now, lawmakers?" the headline read. PMID:12293809

    Misoprostol, a prostaglandin E1 analogue indicated for ulcer treatment, has been widely used as an abortifacient by women in Brazil, where abortion is legal only in cases of rape or incest, or to save the woman's life. Because misoprostol is an inefficient abortifacient, many women who use it have incomplete abortions and need uterine evacuation. We reviewed the records of women admitted to the main obstetric hospital of Fortaleza, capital of Ceará state, Brazil, between January, 1990, and July, 1992, for uterine evacuation after induced abortion. The number of incomplete abortions induced by misoprostol increased substantially during the first half of 1990, and declined thereafter. Of the 593 cases in 1991, 75% were related to misoprostol, 10% to the use of other specified drugs, and 6% to unspecified drugs. For the remaining 9% the procedure used was not recorded; these included 3% in whom abortion had been induced by a clandestine abortionist. The number of uterine evacuations per month fell from 89 in August, 1990, to 62 in July, 1991, when sales of misoprostol in Ceará state were suspended. The fall continued after the sale of misoprostol ceased, to about 20 cases in December, 1991; numbers remained around this level until June, 1992, sustained by clandestine sales. The lack of access to contraception is the main reason for the large numbers of unplanned pregnancies and is a major public health issue for Brazilian women. The prohibition of abortion creates a void in which misuse of medicines is one extra complication, mainly because of the poor control of drug marketing. PMID:8098403

    Neospora caninum is a major cause of abortion in cattle, but the reasons why only some animals abort remain unclear. The immunological control of the parasite in the placenta or by the foetus could be the key to determining the mechanism of abortion and/or transplacental transmission to the foetus. In this study, cytokine gene expression, analysed by real-time RT-PCR, at the maternal (caruncle) and foetal placenta (cotyledon) of heifers infected at 110 days of gestation by intravenous inoculation of N. caninum tachyzoites was compared with the responses in uninfected heifers. Animals were euthanized 3 weeks after infection. Upregulated Th1, Th2 and T-regulatory (Treg) cytokine gene expression was observed in both the maternal and the foetal placenta in the infected group. In the caruncle of infected animals, the main changes included upregulation of IFN-γ, IL-12p40, IL-6 and IL-10. In the cotyledon, the main changes included upregulation of IFN-γ and downregulation of TGF-β, being the later the only cytokine downregulated in the infected group. The observed cytokine expression pattern was associated with alive but transplacentally infected foetuses, suggesting that such cytokine pattern is beneficial to foetal survival, but could have a role in the transplacental transmission of the parasite.

    To learn more about the abortion-related experiences and value orientation of nurses, questionnaires were mailed to 1900 randomly selected community health nurses in the US; 844 (45%) responded. Although only 7% worked in settings where abortions are performed, half provide abortion counseling or referral. Their knowledge about the epidemiology of abortion in the US and recent abortion-related legislation was inadequate, and only 28.6% had received training about the clinical aspects of abortion in nursing school. Respondents' attitudes toward induced abortion were generally supportive; 82.0% believed federal funds should be provided for the procedure, 81.6% agreed women in the first trimester of pregnancy should have the right to choose abortion, and 70.3% supported abortion on demand. However, 27.8% indicated that abortion services in their communities were being negatively impacted by anti-abortion groups; only 9.7% felt that pro-choice groups were having a significant impact in their area. 56.0% reported they had been involved in some political activity relating to abortion, largely voting for a pro-abortion rights candidate or writing letters to legislators. 56.4& indicated they would vote against a candidate they otherwise supported if his or her views on abortion were unacceptable. 21.9% and 16.8% of nurses were involved with local or national Planned Parenthood; under 3% were members of anti-abortion groups. In-service training programs on the abortion issue are recommended to enable community health nurses to expand their counseling and political advocacy skills. PMID:7849540

    The legal approach to abortion is evolving from criminal prohibition towards accommodation as a life-preserving and health-preserving option, particularly in light of data on maternal mortality and morbidity. Modern momentum for liberalization comes from international adoption of the concept of reproductive health, and wider recognition that the resort to safe and dignified healthcare is a major human right. Respect for women's reproductive self-determination legitimizes abortion as a choice when family planning services have failed, been inaccessible, or been denied by rape. Recognition of women's rights of equal citizenship with men requires that their choices for self-determination be legally respected, not criminalized. PMID:15719517

    Tushnet and Seidman attempt to show that, even if Michael Tooley is correct that fetuses have no right to life, others may have a right to their continued existence. Rights-bearing third parties with an interest in the fetus might be biological fathers, prospective adoptive parents, or even society as a whole. Criteria for assessing the legitimacy of claims of interest must be developed and then balanced against the claims of those who support abortion. The authors also discuss principles of bodily autonomy, the destruction as well as the removal of the fetus, and the question of whether legislation prohibiting abortion is mandatory, permissible, or optional.

    Kicker magnets typically represent the most important contributors to the transverse impedance budget of accelerators and storage rings. Methods of reducing the impedance value of the SNS extraction kicker presently under construction and, in view of a future performance upgrade, that of the RHIC abort kicker have been thoroughly studied at this laboratory. In this paper, the investigation of a potential improvement from using ferrite different from the BNL standard CMD5005 is reported. Permeability measurements of several ferrite types have been performed. Measurements on two kicker magnets using CMD5005 and C2050 suggest that the impedance of a magnet without external resistive damping, such as the RHIC abort kicker, would benefit.

    The views of morality enunciated by the Protestant and Catholic churches in the process of France's abortion law revision are examined through an analysis of the testimony of each church and its moral theologians during hearings held from July-November 1973 by the Commission of Cultural, Family, and Social Affairs of the National Assembly concerning the proposed abortion legislation. The offical Catholic Church position, which restated a neoscholastic philosophy with its theory of human nature, natural law, natural right, and natural morality, was opposed by 2 priests who participated as members of other organizations. The moral principles behind the official Catholic position included the sacred and absolute principle of respect for life, the beginning of human life at conception, and the responsibility to protect the fetus as a human being. Internal Catholic challenges to the official position appeared to rest principally on the question of when life begins but also touched on the inappropriateness of viewing unwanted pregnancy as a punishment for sexual activity, the constant recourse to authority of the church, and the reluctance to reexamine questions on new evidence. Faced with the likely replacement of abortion law consistent with Catholic morality by 1 seriously at variance, the French Church and state while justifying their organized opposition to any change. The right of the church to impose its views on the legislature and on society, the view of the cultural context of abortion as a degradation of public attitudes expressed in rejection of children, the necessary connections between sexuality and fertility, the necessity for women to be able to control their fertility if they were to participate fully in society, the debased conditions in which thousands of illegal abortions occurred or the exaggeration of such conditions were other issues.

    In order to understand the evolutionary mechanisms of persistence and diversification within the Caliciviridae, we have been exploiting endemic infection of feline calicivirus within five geographically distinct household groups of cats. By sequencing immunodominant and variable regions of the capsid gene, we identified the relative contribution of the different evolutionary processes employed by the virus to ensure its long-term survival in the host population. Such strategies included progressive evolution of a given variant of a strain through mutation accumulation within an individual, sequential reinfection with either a variant of the same strain or with a different strain, and mixed infection. Recombination between different strains in this study has been reported in detail elsewhere (K. P. Coyne et al., J. Gen. Virol. 87:921-926, 2006). Here, we provide evidence to suggest that true long-term persistent infection in individuals is relatively rare, with the majority of apparent viral carriers undergoing a combination of progressive evolution and cyclical reinfection. Progressive evolution at the individual level and variant reinfection at both the individual and population levels were associated with positive selection. Two measures of evolution rate were determined; for a virus progressively evolving within an individual (1.32 x 10(-2) to 2.64 x 10(-2) substitutions per nucleotide per year, i.e., no transmission) and for a strain circulating within a population (3.84 x 10(-2) to 4.56 x 10(-2) substitutions per nucleotide per year, i.e., including transmission). Reiteration of both progressive evolution and variant reinfection appeared to lead to a gradual increase in the diversity of a given strain of virus, both in the individual and in the population, until eventually new strains emerged.

The potential of nine isolates of entomopathogenic fungi was evaluated after determining percent germination and relative conidial hydrophobicity. However, nutritional indices were evaluated after immersing eighth-instar Rhynchophorus ferrugineus larvae into each isolate suspension (1 × 10⁷ conidia/mL). The results showed that isolates B6884 and M9374 had 44.51% and 39.02% higher conidial hydrophobicity compared with isolate I03011 (least virulent). The results of nutritional index assays revealed a significant reduction in growth indices after infection with different isolates. Compared with control, B6884 and M9374 greatly decreased larval growth by reducing the efficacy of conversion of ingested food (36%-47%) and Efficacy of conversion of digested food (50%-63%). Furthermore, only isolate B6884 induced 100% mortality within 12 days. Compared with control, isolate I03011, possessing the lowest conidial hydrophobicity, only reduced 0.29% of the efficacy of conversion of ingested food (ECI) and 0.48% of the efficacy of conversion of digested food (ECD). Similarly, transcriptomic analysis of genes related to the Red palm weevil (RPW) immune response, including pathogen recognition receptors (C-type lectin and endo-beta-1,4-glucanse), signal modulator (Serine protease-like protein), signal transductors (Calmodulin-like protein and EF-hand domain containing protein) and effectors (C-type lysozyme, Cathepsin L., Defensin-like protein, Serine carboxypeptidase, and Thaumatin-like protein), was significantly increased in larval samples infected with B6884 and M9374. These results suggest that for an isolate to be virulent, conidial hydrophobicity and germination should also be considered during pathogen selection, as these factors could significantly impact host growth and immune defence mechanisms.

    Since its emergence in the 1990s, White Spot Disease (WSD) has had major economic and societal impact in the crustacean aquaculture sector. Over the years shrimp farming alone has experienced billion dollar losses through WSD. The disease is caused by the White Spot Syndrome Virus (WSSV), a large dsDNA virus and the only member of the Nimaviridae family. Susceptibility to WSSV in a wide range of crustacean hosts makes it a major risk factor in the translocation of live animals and in commodity products. Currently there are no effective treatments for this disease. Understanding the molecular basis of disease processes has contributed significantly to the treatment of many human and animal pathogens, and with a similar aim considerable efforts have been directed towards understanding host–pathogen molecular interactions for WSD. Work on the molecular mechanisms of pathogenesis in aquatic crustaceans has been restricted by a lack of sequenced and annotated genomes for host species. Nevertheless, some of the key host–pathogen interactions have been established: between viral envelope proteins and host cell receptors at initiation of infection, involvement of various immune system pathways in response to WSSV, and the roles of various host and virus miRNAs in mitigation or progression of disease. Despite these advances, many fundamental knowledge gaps remain; for example, the roles of the majority of WSSV proteins are still unknown. In this review we assess current knowledge of how WSSV infects and replicates in its host, and critique strategies for WSD treatment. PMID:26797629

    Mannose receptor (MR) is a pattern recognition receptor (PRR) that plays a significant role in immunity responses. Its role has been described extensively in mammals, but very rarely in fish. Recently, with the rapid development of an aquaculture industry cultivating large yellow croaker (Larimichthys crocea), infectious diseases caused by viruses, bacteria and parasites are becoming more frequent and more severe, in particular bacterial infections caused by Vibrio anguillarum, resulting in great economical losses. Extensive use of antibiotics as conventional treatment has led to microenvironment imbalances, development of drug-resistant bacteria and deposition of drug residues, which cause environmental pollution and ultimately affect human health. The purpose of this pilot study was to detect the transcriptional levels of C-type mannose receptor genes MRC1 (4710-bp ORF; encoding 1437 aa; a signal peptide, a SMART RICIN domain, a SMART FN2 domain, eight SMART CLECT domain, and a transmembrane helix region) and MRC2 (3996-bp ORF; encoding 1484 aa; a SMART FN2 domain, eight SMART CLECT domains, and a transmembrane region) in the liver, kidney and spleen tissues of L. crocea challenged by V. anguillarum, to explore the effective domain and the molecular response mechanisms of MRC1 and MRC2, and, ultimately, to explore the possibility of developing a vaccine targeting V. anguillarum infections.

    Abstract Respiratory syncytial virus (RSV) is one of the most important causes of upper and lower respiratory tract infections in infants and young children, for which no effective treatment is currently available. Although the mechanisms of RSV-induced airway disease remain incompletely defined, the lung inflammatory response is thought to play a central pathogenetic role. In the past few years, we and others have provided increasing evidence of a role of reactive oxygen species (ROS) as important regulators of RSV-induced cellular signaling leading to the expression of key proinflammatory mediators, such as cytokines and chemokines. In addition, RSV-induced oxidative stress, which results from an imbalance between ROS production and airway antioxidant defenses, due to a widespread inhibition of antioxidant enzyme expression, is likely to play a fundamental role in the pathogenesis of RSV-associated lung inflammatory disease, as demonstrated by a significant increase in markers of oxidative injury, which correlate with the severity of clinical illness, in children with RSV infection. Modulation of ROS production and oxidative stress therefore represents a potential novel pharmacological approach to ameliorate RSV-induced lung inflammation and its long-term consequences. Antioxid.

    This survey investigated attitudes toward abortion held by 627 medical professionals at the Ramathibodi Hospital in Bangkok in 1980-81. 96% of respondents were either physicians or graduate nurses. The majority were male, 20-30 years of age, single, and Buddhist. 69% of respondents favored making the current Thai abortion law, which restricts abortion, more liberal and an additional 17% favored abortion legalization; only 7% felt that abortion should be further restricted or prohibited. Approval of abortion was widespread for indications such as rape, incest, threat to maternal health, mental illness, and likelihood of fetal abnormalities. Conversely, under 50% of health professionals approved of abortion for indications such as single marital status, high or low maternal age, or child spacing. Sex, age, medical school education, and experience in performing induced abortion had a significant influence on approval rates for indications for abortion. Women, for example, were more conservative than men on indications such as sterilization failure and maternal age; young respondents and physicians tended to be more approving of abortion in cases of contraceptive failure. 62% of respondents indicated a willingness to perform abortions if the law were liberalized and 32% indicated that methods of induced abortion should be taught to medical students.

  9. Multiple mechanisms contribute to impairment of type 1 interferon production during chronic lymphocytic choriomeningitis virus infection of mice.

    2009-06-01

    Type 1 IFNs, innate cytokines with important effector and immunomodulatory properties, are rapidly induced in the acute phase of many virus infections; however, this is generally a transient response that is not sustained during virus persistence. To gain insight into mechanisms that can contribute to down-regulation of type 1 IFN production during virus persistence, we analyzed type 1 IFN production during acute and chronic lymphocytic choriomeningitis virus (LCMV) infection. High-level type 1 IFN production was transiently up-regulated in cells including plasmacytoid and conventional dendritic cells (DCs) following LCMV infection of mice, but LCMV persistence was associated with only low-level type 1 IFN production. Nonetheless, chronically infected mice were able to up-regulate type 1 IFN production in response to TLR3, 7, and 9 ligands, albeit less efficiently than uninfected mice. Splenic DC numbers in mice chronically infected with LCMV were decreased, and the remaining cells exhibited a reduced response to TLR stimulation. LCMV-infected cell lines efficiently up-regulated type 1 IFN production following TLR ligation and infection with a DNA virus, but exhibited a defect in type 1 IFN induction following infection with Sendai, an RNA virus. This block in type 1 IFN production by infected cells, together with abnormalities in DC numbers and functions, likely contribute to the low-level type 1 IFN production in mice chronically infected with LCMV. Impairment of type 1 IFN production may both promote virus persistence and impact on host immunocompetence. Understanding the mechanisms involved may assist in development of strategies for control of virus persistence and superinfection. PMID:19454715

  10. Myxoma and vaccinia viruses exploit different mechanisms to enter and infect human cancer cells

    Myxoma (MYXV) and vaccinia (VACV) viruses have recently emerged as potential oncolytic agents that can infect and kill different human cancer cells. Although both are structurally similar, it is unknown whether the pathway(s) used by these poxviruses to enter and cause oncolysis in cancer cells are mechanistically similar. Here, we compared the entry of MYXV and VACV-WR into various human cancer cells and observed significant differences: 1 - low-pH treatment accelerates fusion-mediated entry of VACV but not MYXV, 2 - the tyrosine kinase inhibitor genistein inhibits entry of VACV, but not MYXV, 3 - knockdown of PAK1 revealed that it is required for a late stage event downstream of MYXV entry into cancer cells, whereas PAK1 is required for VACV entry into the same target cells. These results suggest that VACV and MYXV exploit different mechanisms to enter into human cancer cells, thus providing some rationale for their divergent cancer cell tropisms.

    Candida parapsilosis is the main non-albicans Candida species isolated from patients in Latin America. Mutations in the ERG11 gene and overexpression of membrane transporter proteins have been linked to fluconazole resistance. The aim of this study was to evaluate the molecular mechanisms in fluconazole-resistant strains of C. parapsilosis isolated from critically ill patients. The identities of the nine collected C. parapsilosis isolates at the species level were confirmed through molecular identification with a TaqMan qPCR assay. The clonal origin of the strains was checked by microsatellite typing. The Galleria mellonella infection model was used to confirm in vitro resistance. We assessed the presence of ERG11 mutations, as well as the expression of ERG11 and two additional genes that contribute to antifungal resistance (CDR1 and MDR1), by using real-time quantitative PCR. All of the C. parapsilosis (sensu stricto) isolates tested exhibited fluconazole MICs between 8 and 16 μg/ml. The in vitro data were confirmed by the failure of fluconazole in the treatment of G. mellonella infected with fluconazole-resistant strains of C. parapsilosis. Sequencing of the ERG11 gene revealed a common mutation leading to a Y132F amino acid substitution in all of the isolates, a finding consistent with their clonal origin. After fluconazole exposure, overexpression was noted for ERG11, CDR1, and MDR1 in 9/9, 9/9, and 2/9 strains, respectively. We demonstrated that a combination of molecular mechanisms, including the presence of point mutations in the ERG11 gene, overexpression of ERG11, and genes encoding efflux pumps, are involved in fluconazole resistance in C. parapsilosis.

    Helicobacter pylori colonizes half of the world’s population as the dominant member of the gastric microbiota resulting in a lifelong chronic infection. Host responses toward the bacterium can result in asymptomatic, pathogenic or even favorable health outcomes; however, mechanisms underlying the dual role of H. pylori as a commensal versus pathogenic organism are not well characterized. Recent evidence suggests mononuclear phagocytes are largely involved in shaping dominant immunity during infection mediating the balance between host tolerance and succumbing to overt disease. We combined computational modeling, bioinformatics and experimental validation in order to investigate interactions between macrophages and intracellular H. pylori. Global transcriptomic analysis on bone marrow-derived macrophages (BMDM) in a gentamycin protection assay at six time points unveiled the presence of three sequential host response waves: an early transient regulatory gene module followed by sustained and late effector responses. Kinetic behaviors of pattern recognition receptors (PRRs) are linked to differential expression of spatiotemporal response waves and function to induce effector immunity through extracellular and intracellular detection of H. pylori. We report that bacterial interaction with the host intracellular environment caused significant suppression of regulatory NLRC3 and NLRX1 in a pattern inverse to early regulatory responses. To further delineate complex immune responses and pathway crosstalk between effector and regulatory PRRs, we built a computational model calibrated using time-series RNAseq data. Our validated computational hypotheses are that: 1) NLRX1 expression regulates bacterial burden in macrophages; and 2) early host response cytokines down-regulate NLRX1 expression through a negative feedback circuit. This paper applies modeling approaches to characterize the regulatory role of NLRX1 in mechanisms of host tolerance employed by macrophages to

    Mice vaccinated with radiation-attenuated cercariae display low levels of cellular and humoral immune responses toward schistosomulum antigens, as measured in vitro by lymphocyte blastogenesis and quantitation of anti-larval antibodies by indirect immunofluorescence. Both responses wane with time after vaccination. However subsequent challenge infection provokes immune responses of classical anamnestic character, being both more rapid in appearance and of greater magnitude. Antigen responsive cells appear in lymph nodes draining the challenge site within 24 hours after infection. Both circulating anti-schistosomulum surface antibodies as well as cytophilic IgE anti-worm antigen antibodies increase substantially by 1 week after challenge. All of the anamnestic circulating antibodies belong to the IgG class. Those findings support the concept that vaccine-induced resistance to Schistosoma mansoni infection involves sensitized T and B lymphocytes, and point to the possible role of post-challenge anamnestic responses in the effector mechanism of parasite killing in this model.

    Infective endocarditis (IE) is a highly morbid condition in pregnancy which poses both maternal and fetal risk. In majority of cases, endocarditis occurs only on single valve and usually occurs on valve with structural disease or prosthetic valve. Multi-valvular involvement is not common and so we report a case of native triple valve endocarditis as a complication of post abortal sepsis which was successfully treated medically.

    In the early 2000s, several colonies of Alpine ibex (Capra ibex ibex) in Switzerland ceased growing or began to decrease. Reproductive problems due to infections with abortive agents might have negatively affected recruitment. We assessed the presence of selected agents of abortion in Alpine ibex by serologic, molecular, and culture techniques and evaluated whether infection with these agents might have affected population densities. Blood and fecal samples were collected from 651 ibex in 14 colonies throughout the Swiss Alps between 2006 and 2008. All samples were negative for Salmonella spp., Neospora caninum, and Bovine Herpesvirus-1. Antibodies to Coxiella burnetii, Leptospira spp., Chlamydophila abortus, Toxoplasma gondii, and Bovine Viral Diarrhea virus were detected in at least one ibex. Positive serologic results for Brucella spp. likely were false. Overall, 73 samples (11.2%) were antibody-positive for at least one abortive agent. Prevalence was highest for Leptospira spp. (7.9%, 95% CI=5.0-11.7). The low prevalences and the absence of significant differences between colonies with opposite population trends suggest these pathogens do not play a significant role in the population dynamics of Swiss ibex. Alpine ibex do not seem to be a reservoir for these abortive agents or an important source of infection for domestic livestock in Switzerland. Finally, although interactions on summer pastures occur frequently, spillover from infected livestock to free-ranging ibex apparently is uncommon. PMID:21719818

    Magnaporthe oryzae is a hemibiotrophic fungal pathogen that causes rice (Oryza sativa) blast. Although M. oryzae as a whole infects a wide variety of monocotyledonous hosts, no dicotyledonous plant has been reported as a host. We found that two rice pathogenic strains of M. oryzae, KJ201 and 70-15, interacted differentially with 16 ecotypes of Arabidopsis (Arabidopsis thaliana). Strain KJ201 infected all ecotypes with varying degrees of virulence, whereas strain 70-15 caused no symptoms in certain ecotypes. In highly susceptible ecotypes, small chlorotic lesions appeared on infected leaves within 3 d after inoculation and subsequently expanded across the affected leaves. The fungus produced spores in susceptible ecotypes but not in resistant ecotypes. Fungal cultures recovered from necrotic lesions caused the same symptoms in healthy plants, satisfying Koch's postulates. Histochemical analyses showed that infection by the fungus caused an accumulation of reactive oxygen species and eventual cell death. Similar to the infection process in rice, the fungus differentiated to form appressorium and directly penetrated the leaf surface in Arabidopsis. However, the pathogenic mechanism in Arabidopsis appears distinct from that in rice; three fungal genes essential for pathogenicity in rice played only limited roles in causing disease symptoms in Arabidopsis, and the fungus seems to colonize Arabidopsis as a necrotroph through the secretion of phytotoxic compounds, including 9,12-octadecadienoic acid. Expression of PR-1 and PDF1.2 was induced in response to infection by the fungus, suggesting the activation of salicylic acid- and jasmonic acid/ethylene-dependent signaling pathways. However, the roles of these signaling pathways in defense against M. oryzae remain unclear. In combination with the wealth of genetic and genomic resources available for M. oryzae, this newly established pathosystem allows comparison of the molecular and cellular mechanisms underlying

    The early-1970s abortion legalization led to a significant drop in fertility. We investigate whether this decline represented a delay in births or a permanent reduction in fertility. We combine Census and Vital Statistics data to compare the lifetime fertility of women born in early-legalizing states, whose peak childbearing years occurred in the…

    PubMed

    1997-09-01

    Surveys conducted in Mexico by GIRE in 1992, 1994, and 1995 reveal that over 80% of the national population believes only a woman or a woman and her partner should make abortion decisions. Neither the government, the Church, nor physicians should intervene. Public opinion and the documented social and public health consequences of illegal abortion demonstrate the obsolescence of laws penalizing abortion. Mexico does not have a direct means of converting the opinions of the population into votes and laws. In place of referendums, committees of specialists have been convened; they are limited in number and ability to represent diverse groups, and oriented above all to the losses and gains of political and parliamentary disputes. The electoral reform of 1995-96 was a good example of the question under debate getting lost in partisan maneuvering. The Federal District and four states have initiated development of the referendum process, but the procedures have been too cumbersome and the results disappointing. In the current day, opinions are often formed not by following a rational process, but by bombardment with advertising appealing to irrational emotions. The democratic effects of referendum should be furthered by guaranteeing fair and exhaustive exposure of all points of view before the vote is held. GIRE recommends that a referendum on decriminalization of abortion should be preceded by a period of at least two years for public debate and reflection, and that the Federal Electoral Institute should organize the debate and the referendum.

    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. PMID:27285423

    This report deals with the acute onset of an abortion outbreak and high sow mortality in one pig herd consisted of 1,200 pigs and 120 sows on Jeju Island, Korea. Affected pregnant sows showed clinical signs, including high fever, gradual anorexia, vomiting, depression, recumbency, prostration, abortion, and a few deaths. Four dead sows, five aborted fetuses from the same litter, and 17 sera collected from sows infected or normal were submitted to the Pathology Division of the National Veterinary Research and Quarantine Service for diagnostic investigation. Grossly, hepatomegaly and splenomegaly were observed in sows. Multiple necrotic foci were scattered in the lungs, liver, spleen, and lymph nodes. Microscopically, multifocal necrotizing lesions and protozoan tachyzoites were present in the lesions. Tachyzoites of Toxoplasma (T.) gondii were detected immunohistochemically. Latex agglutination showed that the sera of 7 of 17 (41.2%) sows were positive for antibody to T. gondii. The disease outbreak in this herd was diagnosed as epizootic toxoplasmosis. To our knowledge, this is the first report of porcine toxoplasmosis with a high abortion rate and sow mortality in Korea. PMID:19461210

    The birth rate is a major concern in contemporary society today. Socialist countries having the material wherewithal and cultural wealth to maintain their populations have a genuine interest in population growth and maternity is therefore encouraged. The decision to have children lies with each individual family and does not involve society directly, except for the significant number of women who regulate their family size by having an abortion. In connection with the severity of such an intervention, a study of social and hygienic aspects of induced abortion was conducted in Odessa. The information was gathered anonymously among women who came to the gynecological department of a city hospital. 6.1% of the women were under age 20 and this figure may increase in the future. In the U.S. that figure already constitutes 1/3 of all abortions. 47.5% said they had had 3 previous abortions. 13.4% had no children, and 48.8% had 1 child. None of the women with no children thought of that as being the ideal. As reason for the abortion 31.7% gave irregular housing and living conditions, 12.2% unsatisfactory material well-being, 17.1% health reasons, 7.3% enough children already in the family, and 7.3% sickness of children and husband. In 24.4% of cases the husband was indifferent, and in 35.4% insisted on, and in 40.1% was against the woman having an abortion. 60% were thus probably poorly informed about the harmfulness of the operation. 39% of women did not use any contraception. Only 20% had received any information regarding contraceptives. Only 1/3 of obstetricians regularly instruct their patients about the use of contraceptives. Half of the nurses do not touch upon the subject due to lack of time and since instruction in birth control methods is not considered obligatory. Nevertheless it is important for women's health that during clinical examinations risk factors of abortion and the purposefulness of contraception are pointed out. PMID:3367727

  6. Catholics and abortion: authority vs. dissent.

    PubMed

    1985-01-01

    A paid advertisement, appearing in "The New York Times" on October 4, 1984 under the sponsorship of a group called Catholics for a Free Choice, contended that there is more than 1 legitimate, i.e., theologically and ethically defensible, viewpoint on abortion within the Roman Catholic tradition. The advertisement called for a dialogue on abortion among Catholics; a dialogue that would acknowledge this situation of pluralism, not only in regard to practice (Catholics have about the same proportion of abortions as Protestants in the US) but in regard to the ethical state of the question. The ad explicitly asked for the cessation of institutional sanctions against those with dissenting positions on abortion. In the months following the ad's appearance, its admonition that dissenters should not be penalized has not been heeded. The chief initiative in this repression has come from the Vatican. In early December 1984 there arrived in the mailboxes of the religious superiors or bishops of the 4 priests and brothers and most of the 24 nuns who signed the statement a letter from the head of the Vatican's Sacred Congregation for Religious and Secular Institutes. This letter, dated November 30, 1984, stated that the position taken in "The New York Times" advertisement was "in contradiction to the teachings of the Church" and that the ad's signers were "seriously lacking in religious submission to the mind of the Magisterium." Any signer who declined to make a public retraction was to be warned by the superior with an explicit threat of dismissal from his/her religious community. The 2 priests and the 2 brothers made "pro forma" statements of retraction. None of the nuns who signed was willing to do so. When the nun-signers, through their religious superiors, indicated that they would not retract the statement nor would the superiors threaten them with dismissal, the Sacred Congregation appeared to back off. To date, none of the nuns has fully complied with the request to

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

  8. Visualising abortion: emotion discourse and fetal imagery in a contemporary abortion debate.

    PubMed

    Hopkins, Nick; Zeedyk, Suzanne; Raitt, Fiona

    2005-07-01

    This paper presents an analysis of a recent UK anti-abortion campaign in which the use of fetal imagery--especially images of fetal remains--was a prominent issue. A striking feature of the texts produced by the group behind the campaign was the emphasis given to the emotions of those viewing such imagery. Traditionally, social scientific analyses of mass communication have problematised references to emotion and viewed them as being of significance because of their power to subvert the rational appraisal of message content. However, we argue that emotion discourse may be analysed from a different perspective. As the categorisation of the fetus is a social choice and contested, it follows that all protagonists in the abortion debate (whether pro- or anti-abortion) are faced with the task of constructing the fetus as a particular entity rather than another, and that they must seek to portray their preferred categorisation as objective and driven by an 'out-there' reality. Following this logic, we show how the emotional experience of viewing fetal imagery was represented so as to ground an anti-abortion construction of the fetus as objective. We also show how the arguments of the (pro-abortion) opposition were construed as totally discrepant with such emotions and so were invalidated as deceitful distortions of reality. The wider significance of this analysis for social scientific analyses of the abortion debate is discussed. PMID:15893054

    Brucella is a facultative intracellular pathogen that causes zoonotic infection known as brucellosis which results in abortion and infertility in natural host. Humans, especially in low income countries, can acquire infection by direct contact with infected animal or by consumption of animal products and show high morbidity, severe economic losses and public health problems. However for survival, host cells develop complex immune mechanisms to defeat and battle against attacking pathogens and maintain a balance between host resistance and Brucella virulence. On the other hand as a successful intracellular pathogen, Brucella has evolved multiple strategies to evade immune response mechanisms to establish persistent infection and replication within host. In this review, we mainly summarize the “Stealth” strategies employed by Brucella to modulate innate and the adaptive immune systems, autophagy, apoptosis and possible role of small noncoding RNA in the establishment of chronic infection. The purpose of this review is to give an overview for recent understanding how this pathogen evades immune response mechanisms of host, which will facilitate to understanding the pathogenesis of brucellosis and the development of novel, more effective therapeutic approaches to treat brucellosis.

    Vascular disorders have a direct link to mortality in the acute phase of Trypanosoma cruzi infection. However, the underlying mechanisms of vascular dysfunction in this phase are largely unknown. We hypothesize that T. cruzi invades endothelial cells causing dysfunction in contractility and relaxation of the mouse aorta. Immunodetection of T. cruzi antigen TcRBP28 was observed in endothelial cells. There was a decreased endothelial nitric oxide synthase (eNOS)-derived NO-dependent vascular relaxation, and increased vascular contractility accompanied by augmented superoxide anions production. Endothelial removal, inhibition of cyclooxygenase 2 (COX-2), blockade of thromboxane A2 (TXA2) TP receptors, and scavenger of superoxide normalized the contractile response. COX-2, thromboxane synthase, inducible nitric oxide synthase (iNOS), p65 NFκB subunit and p22(phox) of NAD(P)H oxidase (NOX) subunit expressions were increased in vessels of chagasic animals. Serum TNF-α was augmented. Basal NO production, and nitrotyrosine residue expression were increased. It is concluded that T. cruzi invades mice aorta endothelial cells and increases TXA2/TP receptor/NOX-derived superoxide formation. Alongside, T. cruzi promotes systemic TNF-α increase, which stimulates iNOS expression in vessels and nitrosative stress. In light of the heart failure that develops in the chronic phase of the disease, to understand the mechanism involved in the increased contractility of the aorta is crucial. PMID:26988253

    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. PMID:12807304

    Anti-choice efforts to eliminate and/or restrict abortion coverage in US health care reform proposals were overwhelmingly rejected by Congressional committees on June 22 and 23, 1994. The committees rejected Kentucky Republican Representative Jim Bunning's amendment to remove abortion services except in cases of life endangerment, rape, or incest; Wisconsin Democrat Gerald Kleczka's attempt to let health plans opt out of providing abortion coverage; Pennsylvania Republican Rick Santorum's attempt to prevent the health plan from preempting state constitutional laws and regulations on abortion; amendments by Pennsylvania Democrat Ron Klink to drop abortion coverage except in cases of life endangerment, rape, or incest, and to guarantee against the plan overturning state regulations on abortion; and an amendment by Wisconsin Republican Steve Gunderson to allow plans to single out abortion from the guaranteed benefits package and offer plans without that coverage as well as to allow self-insured businesses to opt out of abortion coverage. Moreover, a final proposal to move abortion services into an optional benefit category was withdrawn and the House Education and Labor Committee refused to endorse abortion restrictions in its version of Clinton's HR 3600 health care proposal. The Senate Labor and Human Resources Committee previously defeated restrictions on abortion coverage. PMID:12345512

    This article grew out of a keynote address prepared for the conference, "From Abortion to Contraception: Public Health Approaches to Reducing Unwanted Pregnancy and Abortion Through Improved Family Planning Services," held in Tbilisi, Georgia, USSR in October 1990. The article reviews the legal, religious, and medical situation of induced abortion in Europe in historical perspective, and considers access to abortion services, attitudes of health professionals, abortion incidence, morbidity and mortality, the new antiprogestins, the characteristics of abortion seekers, late abortions, postabortion psychological reactions, effects of denied abortion, and repeat abortion. Special attention is focused on the changes occurring in Romania, Albania, and the former Soviet Union, plus the effects of the new conservatism elsewhere in the formerly socialist countries of central and eastern Europe, particularly Poland. Abortion is a social reality that can no more be legislated out of existence than the controversy surrounding it can be stilled. No matter how effective family planning services and practices become, there will always be a need for access to safe abortion services. PMID:1557791

  16. Eliminating the phrase "elective abortion": why language matters.

    Janiak, Elizabeth; Goldberg, Alisa B

    2016-02-01

    The phrase "elective abortion" is often used to describe induced abortions performed for reasons other than a direct, immediate threat to maternal physical health. We argue that the term "elective abortion" is variably defined, misrepresents the complexity and multiplicity of indications for abortion and perpetuates stigma. In practice, restricting access to abortion at the legal, regulatory or institutional level based on subjective perceptions of patient need constrains health care providers' ability to act according to their best clinical judgments and limits patient access to care. The phrase "elective abortion" should be eliminated from scientific and medical discourse to prevent further damage to the public understanding of the variety of indications for which women require expeditious and equitable access to induced abortion.

  17. Estimates of demand for abortion among Soviet immigrants in Israel.

    1992-01-01

    In 1990, more than 185,000 Soviet Jews emigrated to Israel, increasing Israel's population by 4 percent; 148,000 more arrived in 1991. Given the fertility and abortion patterns prevailing among Soviet women in their native country, this article inquires about the short-range expected increase in abortion demand in Israel engendered by this large migratory inflow. Estimation techniques based on the abortion experience of an earlier wave of Soviet-born immigrants in Israel reveal that the increase in requests for abortion brought about by the 1990 immigrants may reach up to 14 percent, and as high as 24 percent for the combined immigration waves of 1990 and 1991. The expanded demand for abortions in Israel engendered by the new Soviet immigrants necessitates an expansion of both family planning services and of the medical committees entitled to grant a legal abortion. A failure in these fields would benefit illegal abortion. PMID:1412599

    The purpose of this study was to explore the reasons women in rural, southern Gabon, Africa, chose to terminate their pregnancies, the methods used to induce abortions, and postabortion effects experienced by these women. Abortion is illegal in this country. A descriptive qualitative design guided the methodology for this study. Five women with a history of induced abortion were interviewed in-depth for their abortion story. Reasons cited for an abortion included lack of financial and partner support. Abortion methods included oral, rectal, and vaginal concoctions of leaves, bark, and water and over-the-counter medications, including misoprostol. Affects were physical, spiritual, and relational. Health care professionals need to provide women with guidance for appropriate contraceptive usage. Abortion after-care of women with physical and spiritual needs is important. Future research is suggested on the use of misoprostol in Gabon to understand its affects on women's reproductive health. PMID:17202528

    This article analyses, after introductory comments on the legal situation in the German Empire and the Weimar Republic, the legal basis for induced abortions during National Socialist rule in Germany. During this period the first legal definition for eugenically and medically indicated abortions was established. At the same time the prohibition of induced abortions outside these criteria was controlled more strictly and violations were punished more severely. This concerned abortions mainly for social reasons. The intention was to legalize abortion for those deemed "less worthy" while, at the same time, to minimise the number of abortions of those considered as "more valuable" to society. The main thrust of this policy was to increase the birth rate of "valuable" citizens. The second part of this paper focuses on eugenic and medical abortions at the University of Freiburg's Maternity Hospital. PMID:11050762

    1991-01-01

    The mechanism by which CD8+ T cells from human immunodeficiency virus (HIV)-infected individuals suppress HIV replication in acutely infected CD4+ T cells was investigated. Cytotoxicity was not involved, as the antiviral activity of the CD8+ cells did not correlate with the ability to lyse HIV-infected or uninfected CD4+ T cells. In addition, the frequency of HIV-infected CD4+ cells increased during coculture with CD8+ T cells even in the absence of detectable levels of virus replication. Moreover, separation of the CD4+ and CD8+ cells by a 0.4-micron-pore-size filter delayed HIV replication, indicating a role, at least in part, for a soluble factor. However, cell contact was required for optimal antiviral activity. These results extend further the observation on the mechanism of antiviral HIV activity by CD8+ cells from infected individuals. They support the conclusion that CD8+ cells can play a major role in preventing development of disease in HIV-infected individuals. PMID:1920621

    Bunyamwera virus (BUNV) is the prototype virus for both the Orthobunyavirus genus and the Bunyaviridae family. Different strains of BUNV have been associated with clinical diseases in domestic animals, mainly ruminants. During 2013, in Argentina's Santa Fe Province, three new isolates of BUNV were recovered from the brain and spleen of two horses with encephalitis, and from the brain of an aborted equine fetus. This isolation of BUNV from domestic animals provided the first association of BUNV infection with disease of the central nervous system and abortion in equines in Argentina. PMID:26183295

    Lactococcal siphophages from the 936 and P335 groups infect the Gram-positive bacterium Lactococcus lactis using receptor binding proteins (RBPs) attached to their baseplate, a large multiprotein complex at the distal part of the tail. We have previously reported the crystal and electron microscopy (EM) structures of the baseplates of phages p2 (936 group) and TP901-1 (P335 group) as well as the full EM structure of the TP901-1 virion. Here, we report the complete EM structure of siphophage p2, including its capsid, connector complex, tail, and baseplate. Furthermore, we show that the p2 tail is characterized by the presence of protruding decorations, which are related to adhesins and are likely contributed by the major tail protein C-terminal domains. This feature is reminiscent of the tail of Escherichia coli phage λ and Bacillus subtilis phage SPP1 and might point to a common mechanism for establishing initial interactions with their bacterial hosts. Comparative analyses showed that the architecture of the phage p2 baseplate differs largely from that of lactococcal phage TP901-1. We quantified the interaction of its RBP with the saccharidic receptor and determined that specificity is due to lower koff values of the RBP/saccharidic dissociation. Taken together, these results suggest that the infection of L. lactis strains by phage p2 is a multistep process that involves reversible attachment, followed by baseplate activation, specific attachment of the RBPs to the saccharidic receptor, and DNA ejection.

    Background. Mini-host models are simple experimental systems to study host-pathogen interactions. We adapted a Drosophila melanogaster infection model to evaluate the in vivo effect of different mechanisms of linezolid (LNZ) resistance in Staphylococcus aureus. Methods. Fly survival was evaluated after infection with LNZ-resistant S. aureus strains NRS119 (which has mutations in 23S ribosomal RNA [rRNA]), CM-05 and 004-737X (which carry cfr), LNZ-susceptible derivatives of CM-05 and 004-737X (which lack cfr), and ATCC 29213 (an LNZ-susceptible control). Flies were then fed food mixed with LNZ (concentration, 15–500 µg/mL). Results were compared to those in mouse peritonitis, using LNZ via oral gavage at 80 and 120 mg/kg every 12 hours. Results. LNZ at 500 µg/mL in fly food protected against all strains, while concentrations of 15–250 µg/mL failed to protect against NRS119 (survival, 1.6%–20%). An in vivo effect of cfr was only detected at concentrations of 30 and 15 µg/mL. In the mouse peritonitis model, LNZ (at doses that mimic human pharmacokinetics) protected mice from challenge with the cfr+ 004-737X strain but was ineffective against the NRS119 strain, which carried 23S rRNA mutations. Conclusions. The fly model offers promising advantages to dissect the in vivo effect of LNZ resistance in S. aureus, and findings from this model appear to be concordant with those from the mouse peritonitis model.

    Tuberculous pleurisy is a frequent extrapulmonary manifestation characterized by accumulation of fluid and inflammatory cells in the pleural space. Here, we investigated the mechanisms of T-lymphocyte accumulation in the pleural space by using a murine model of pleurisy induced by Mycobacterium bovis BCG. Intrathoracic (i.t.) injection of BCG (4.5 x 10(5) bacteria/cavity) induced accumulation of T lymphocytes in the pleural cavities of C57BL/6 mice. We observed the presence of CFU in pleural washes conducted 1, 2, 3, 7, and 15 days after pleurisy induction. Pretreatment with fucoidan inhibited T-lymphocyte accumulation at 1 day, but not at 15 days, after BCG-induced pleurisy. Accordingly, adoptive transfer of fluorescein isothiocyanate-labeled blood mononuclear cells to infected mice showed that T lymphocytes migrated into the pleural cavity 1 day (but not 15 days) after BCG injection. Cell-free pleural wash fluids recovered from mice 1 day after BCG i.t. stimulation (day 1 BCG-PW), but not day 7 or day 15 BCG-PW, induced in vitro T-cell transmigration, which was dependent on L-, P-, and E-selectins. In contrast, day 7 BCG-PW (but not day 1 BCG-PW) induced in vitro T-lymphocyte proliferation via interleukin-2 (IL-2) and gamma interferon (IFN-gamma). Accordingly, in vivo IL-2 or IFN-gamma neutralization abolished T-lymphocyte accumulation 7 days after pleurisy induction. Our results demonstrate that pleural infection induced by BCG leads to T-lymphocyte accumulation in two waves. The acute phase depends on selectin-mediated migration, while the second wave of T-lymphocyte accumulation seems to depend on a local proliferation induced by cytokines produced in situ.

    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.

  8. Biblical views on abortion: an Episcopal perspective.

    Much scholarly work has been done to determine the biblical and traditional attitudes about abortion. One must ask what was said and why, what was its context, and inquire about what was not said as well. This discussion identifies some of the conclusions reached in scholarly literature. The word "abortion" is not mentioned in the Bible, but much in the Bible speaks to the issue. The most obvious passage is from Exodus 21:22-25. This part of the Covenant Code legislates the case of a pregnant woman who becomes involved in a brawl between 2 men and has a miscarriage. A distinction is then made between the penalty that is to be exacted for the loss of the fetus and injury to the woman. For the fetus, a fine is paid as determined by the husband and the judges. However, if the woman is injured or dies, "lex talionis" is applied -- life for life, eye for eye, etc. The story has somewhat limited application to the current abortion debate since it deals with accidental and not willful pregnancy termination. Even so, the distinction made between the woman and the fetus is important. The woman is valued as a person under the convenant; the fetus is valued as property. Its status is certainly inferior to that of the woman. This passage gives no support to the parity argument that gives equal religious and moral worth to woman and fetus. The bibilical portrait of person does not begin with an explanation of conception but with a portrayal of the creation of Adam and Eve. Thus, the biblical portrait of a person is that of a complex, many-sided creature with the god-like ability and responsibility to make choices. The fetus does not meet those criteria. When considering the issue of abortion, the one who unquestionably fits this portrait of personhood is the pregnant woman. The abortion question focuses on the personhood of the woman, who in turn considers the potential personhood of the fetus in terms of the multiple dimensions of her own history and the future.

    A total of 904 sera from dairy cattle in 11 provinces of central Thailand were tested for antibodies to Neospora caninum employing the indirect fluorescent antibody test (IFAT). Fifty four (6%) cattle were positive in IFAT, titres of 1:200 (16 cattle), 1:400 (9 cattle), 1:800 (14 cattle), 1:1600 (7 cattle), 1:3200 (6 cattle) and two positives. No significant difference was observed among the provinces. The seropositivity for Toxoplasma gondii by a commercial latex agglutination test was 4% (2 out of 50) in positive sera, 2.9% (2 out of 69) in negative sera for anti-Neospora antibodies and 3.4% (4 out of 119) in total. The results of the IFAT were not associated with the presence of antibodies to T. gondii in bovine sera. Furthermore, the cause of abortions experienced in neighbouring three areas in the northeast, where pregnant heifers were newly introduced into small-scale farms from the central region, was investigated. The positive rates for anti-N. caninum antibody were 12, 28 and 44% at a cut-off titre of 1:200, and cattle were suspected to be infected after the introduction. In the area with the highest rate, seven out of eight aborting cattle were positive for antibodies to N. caninum while other two areas had similar abortion rates in both negative and positive cattle. However, in the latter two areas, positive rates for Trypanosoma evansi antigen along with parasitaemic animals were observed by an antigen-detection ELISA, but not for the former area. Considering the endemic diseases of the areas, Neospora was presumed to be responsible for the abortions in the former area while the examination results pointed out T. evansi as the most probable cause in the latter two areas. This is the first report of Neospora-associated abortion in Southeast Asia. PMID:10489202

    Pregnancy failure is a common event and often of unknown cause. Some viruses are thought to cause abortions including the adeno-associated viruses (AAV), viruses which are regarded as being without any definitive association to any human disease. This study investigated AAV infection in 81 human abortions, both spontaneous and intentional that occurred up to the 23rd week of gestation. Nucleic acid of AAV-2, 3, and 5 types from 118 decidual and chorionic tissues, collected from the patients in this study, was amplified by nested-PCR. In situ hybridization (ISH) was developed with a digoxigenin-labeled AAV probe in paraffin embedded tissues from the AAV positive cases. AAV was observed in 28.4% (23/81) of the cases, of which, 78.3% (18/23) were in the decidua and 21.7% (5/23) in the extravillous trophoblast, the chorionic plate, or chorionic villi fragments. AAV-2, the only type detected, occurred in 32.3% (22/68) and in 7.7% (1/13) of the spontaneous and intentional abortions, respectively. ISH revealed AAV in the decidua, chorionic tissue or chorionic plate and extravillous trophoblast. The detection of only AAV-2 type indicates that it is the most frequent in the population studied and/or shows tissue tropism. The presence of AAV in decidual or trophoblastic cells in cases of abortion, as observed by ISH, implies that the virus could jeopardize the pregnancy. The significant predominance in spontaneous cases suggests possibly a causal association between AAV and abortion. PMID:20827766

    This work reviews the suggested mechanisms which result in programmed cell death in human HIV infection. Here we present state-of-the-art scientific information related to the newly rediscovered phenomenon of Apoptosis, and to its biological relevance in the pathogenesis of HIV disease. General features of this phenomenon are reviewed, as well as available evidence for its occurrence and possible role in AIDS pathogenesis. A complex series of cellular and molecular events leading to cellular apoptosis are also reviewed and discussed. They include events which take place at the cell membrane level and those which occur at the intramembrane level and cytoplasmic locations, which result from the immunological activation of affected cells. Cellular events which follow and occur within the mitochondrial space and at the nuclear level are also discussed. The biological significance of all these phenomena is summarized in a theoretical scheme, which attempts to integrate all cellular events leading a primed cell into its HIV-induced programmed death.

    Tuberculosis (TB), caused by the bacterium Mycobacterium tuberculosis (Mtb), is a growing international health crisis. Mtb is able to persist in host tissues in a non-replicating persistent (NRP) or latent state. This presents a challenge in the treatment of TB. Latent TB can re-activate in 10% of individuals with normal immune systems, higher for those with compromised immune systems. A quantitative understanding of latency-associated virulence mechanisms may help researchers develop more effective methods to battle the spread and reduce TB associated fatalities. Leveraging BioXyce's ability to simulate whole-cell and multi-cellular systems we are developing a circuit-based framework to investigate the impact of pathogenicity-associated pathways on the latency/reactivation phase of tuberculosis infection. We discuss efforts to simulate metabolic pathways that potentially impact the ability of Mtb to persist within host immune cells. We demonstrate how simulation studies can provide insight regarding the efficacy of potential anti-TB agents on biological networks critical to Mtb pathogenicity using a systems chemical biology approach

    Hemoglobin degradation during the asexual cycle of Plasmodium falciparum is an obligate process for parasite development and survival. It is established that hemoglobin is transported from the host erythrocyte to the parasite digestive vacuole (DV), but this biological process is not well characterized. Three-dimensional reconstructions made from serial thin-section electron micrographs of untreated, trophozoite-stage P. falciparum-infected erythrocytes (IRBC) or IRBC treated with different pharmacological agents provide new insight into the organization and regulation of the hemoglobin transport pathway. Hemoglobin internalization commences with the formation of cytostomes from localized, electron-dense collars at the interface of the parasite plasma and parasitophorous vacuolar membranes. The cytostomal collar does not function as a site of vesicle fission but rather serves to stabilize the maturing cytostome. We provide the first evidence that hemoglobin transport to the DV uses an actin-myosin motor system. Short-lived, hemoglobin-filled vesicles form from the distal end of the cytostomes through actin and dynamin-mediated processes. Results obtained with IRBC treated with N-ethylmaleimide (NEM) suggest that fusion of hemoglobin-containing vesicles with the DV may involve a soluble NEM-sensitive factor attachment protein receptor-dependent mechanism. In this report, we identify new key components of the hemoglobin transport pathway and provide a detailed characterization of its morphological organization and regulation. PMID:25724884

    This article reviews the current legal status of abortion in Australia and its implications. Australian abortion law has been a matter for the states since before Federation. In the years since Federation there have been significant reforms and changes in the abortion laws of some jurisdictions, although not all. Across Australia there are now nine sets of laws, state and Commonwealth, concerned with abortion. The test of a lawful abortion varies greatly across jurisdictions. In a number of states and territories, it is necessary to establish a serious risk to the physical or mental health of the woman if the pregnancy was to continue. In some cases, the certification of two doctors is required, particularly for abortions at later gestations. There are also physical restrictions on access, such as in South Australia and the Northern Territory where abortion must take place in a hospital. Only in the ACT has abortion been removed from the criminal law altogether. Variations in the law and restrictions arising from these are not consistent with the aims and provision of the universal, accessible health care system aspired to in Australia. There is an urgent need for overall reform and the introduction of uniformity to Australia's abortion laws, including removal of abortion from the criminal law. PMID:25871844

    Comments were made about the US legislative agenda to provide universal health insurance coverage and basic health care which must cover the most controversial procedure, abortion. Compromises have been offered that would deny abortion to any women receiving a government subsidy, that would allow employers to opt out of coverage, that would allow a nurse or doctor to opt out of performing an abortion, and that would allow women to refuse abortion insurance coverage. Neither prochoice nor prolife groups have cooperated in reducing the demand for abortion. Over the past several years, the debate has evolved to the point where prolife groups are trying to make abortion impossible, not just illegal, by murdering doctors and escorts and blocking clinic entrances. A CNN poll revealed in the beginning of August 1994 that 8% agreed that force was justifiable for preventing abortion, and 3% agreed that killing a doctor was justifiable. Members of Congress have attempted to create a neutral or safety zone to no avail. This has created the illusion of peace, but the abortion war rages on. Health care reform must address this controversial question and move in one direction or another. The present system perpetrates a double standard because the financially comfortable are covered for abortion care, and the poor under Medicaid are denied abortion coverage. PMID:12289883

    The illegality of abortion in Brazil is questioned more and more. It would seem obvious that the prohibition of abortion would result in a decrease in the number of abortions, but upon closer observation, the opposite is true. Abortion related legislation in Brazil is among the most severe in the world. Both the physician and the patient are equally punishable, but this did not stop Brazilian women from having 3.5 million abortions/year. Countries with less severe laws have a much lower abortion rate. There have been extreme physiological and social consequences in Brazil as a result of abortion's illegality. The woman is not only a criminal, she is also a sinner in the eyes of the Church. In most cases, especially in low-income areas, abortion can lead to complications and death. Although there are no statistical data on the number of deaths due to illegal abortion, they would no doubt be alarming. An unwanted, unterminated pregnancy can have disastrous effects upon the mother, the child, and their relationship. These negative effects have been well documented. Prohibition will keep abortion out of the mainstream of national debate and aggravate the situation. A person's sexuality cannot be suppressed and considered evil. In lower income levels, unwanted pregnancy should not be a punishment for being poor. The legalization movement will grow, as it has in developed nations. The members of the Brazilian Society for Scientific Progress must remain active in the debate, because they cannot ignore something of such national importance. PMID:12314816

    Background: Induced abortion is not only a serious threat for women’s health, but also a controversial topic for its ethical and moral problems. We aimed to evaluate the relationship between neutralization techniques and attempting to commit abortion in married women with unintended pregnancy. Methods: After in-depth interviews with some women who had attempted abortion, neutralization themes were gathered. Next, to analyze the data quantitatively, a questionnaire was created including demographic and psychosocial variables specifically related to neutralization. The participants were divided into two groups (abortion and control) of unintended pregnancy and were then compared. Results: Analysis of psychosocial variables revealed a significant difference in the two groups at neutralization, showing that neutralization in the control group (56.97±10.24) was higher than that in the abortion group (44.19±12.44). To evaluate the findings more accurately, we examined the causal factors behind the behaviors of the abortion group. Binary logistic regression showed that among psychosocial factors, neutralization significantly affected abortion (95% CI=1.07-1.35). Conclusion: Despite the network of many factors affecting induced abortion, neutralization plays an important role in reinforcing the tendency to attempt abortion. Furthermore, the decline of religious beliefs, as a result of the secular context of the modern world, seems to have an important role in neutralizing induced abortion. PMID:25349851

    One hundred sixty-one couples with clinical histories of unexplained recurrent spontaneous abortions were analyzed in part for human leukocyte antigens, antibodies to paternal lymphocytes, and mixed lymphocyte culture reactions. All sera with antipaternal antibodies were investigated on a cell panel and absorbed with various tissues and heparin to help define antigenic specificities, and the couples were categorized as primary or secondary aborters. Primary but not secondary aborters were found to share more human leukocyte antigens with their mates than did 103 control fertile couples. Lymphocytotoxins were rarely identified in primary but were commonly present in secondary aborter sera. Results of mixed lymphocyte culture reactions with primary aborting couples showed an intrinsic cellular inability for the wives to recognize their husbands' cells. Secondary aborting couples' mixed lymphocyte culture reactions also were depressed but as a result of an inhibiting substance in the wives' sera. Thirty-three primary aborting women were treated by immunotherapy with leukocyte infusions as a prophylactic source of trophoblast-lymphocyte cross reactive antigen stimulation to immunologically protect their pregnancies. Eighty-nine percent of primary aborting patients delivered successfully. Six secondary aborting women were treated with heparin therapy; two of these delivered normal infants, two are pregnant, and two have aborted. Clinical implications for immunologic testing and immunotherapy in pregnancy failures are discussed. PMID:2935759

    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.

    Abortion is illegal in Burkina Faso except in cases of incest, rape, fetal defect, or when the woman's life or physical health is endangered. As a result, abortion procedures are often conducted illegally and unsafely and measuring incidence proves difficult. We estimate incidence of abortion and associated morbidity using two methodologies. The first is the Abortion Incidence Complications Method (AICM), which uses information on women hospitalized for abortion-related complications as well as health professionals' assessments of the proportion of women who seek treatment for complications from unsafe abortions. The second is the Anonymous Third Party Reporting (ATPR) method, which entails surveying women about their confidantes' abortions. We conclude that the AICM yields a more accurate result. We estimate that 87,200 abortion procedures were carried out in 2008, representing 25 for every 1,000 women aged 15-49. More than one in four procedures resulted in complications treated at a health facility. The abortion rate estimated using the ATPR approach was 72 percent of that estimated with the AICM. The ATPR method yields information on the characteristics of the women who have abortions as well as the providers and methods they use. PMID:21972666
