All pestiviruses are important veterinary pathogens causing economic losses in cattle, sheep and pigs. Besides the important economical losses, pestiviruses may compromise the normal immune response to other pathogens and increase the severity of other infections in sheep. In this study, aborted foetuses (cattle and sheep) in either coastal or inland Black Sea region of Turkey were surveyed for the presence of RNA from pestiviruses (bovine viral diarrhoea virus (BVDV), border disease virus (BDV)). The presence of BVDV RNA was found in 6 of 21 aborted calves (28.57%), although BDV RNA was detected in 14 of 21 aborted lambs (66.66%) by reverse transcriptase polymerase chain reaction. This study also investigates the distribution of viral RNA within the brain, liver and lung of aborted foetuses. The viral RNA positivity rates for the organs varied and were as follows: brain 40.47% and liver and lung 38.09%. The results revealed that pestiviruses are important abort pathogen in the provinces of northern Turkey.

Due to moral, religious, and cultural sensibilities, the topic of abortion still gives rise to controversy. The ongoing public debate has become visibly polarized with the usage of the pro-life versus pro-choice rhetoric. The aim of the current research was to investigate whether the language used in abortion discourse can affect people's attitudes by changing their attributions of humanity to unborn. Across three experimental studies we showed that participants who read about a 'foetus', compared to a 'child' declared higher support for elective abortion (Study 1; N = 108), this effect can be explained by greater humanness, as reflected in human nature traits, attributed to the child (vs. the foetus; Study 2; N = 121). The effect is mediated uniquely by attribution of human nature, but not by human uniqueness traits (Study 3; N = 120). These findings serve as a starting point for discussion of the role of language in shaping attitudes on abortion and other morally ambiguous issues.

Adherence of Tritrichomonas foetus to bovine vaginal epithelial cells (VECs) in vitro was investigated with fresh washed bovine VECs and log-phase cultures of T. foetus. Observation under phase-contrast microscopy showed that T. foetus usually adhered first by the posterior flagellum and later by the body. Significantly more keratinized squamous epithelial cells were detected with attached parasites than nonkeratinized round epithelial cells. The optimal pH range for attachment was 6.0 to 7.5, with peak attachment at pH 6.5 for squamous VECs. Surface-reactive bovine antiserum to T. foetus prevented adherence to bovine squamous VECs. Inhibition of adherence occurred at nonagglutinating, nonimmobilizing serum dilutions. Antiserum fractions enriched for immunoglobulin G1 inhibited adherence, but fractions enriched for immunoglobulin G2 did not. The inhibitory antiserum was specific for several medium- to high-molecular-weight membrane antigens as detected in Western blots (immunoblots). The ability of surface-reactive antibodies to prevent adherence and to agglutinate and immobilize T. foetus indicates that they may be protective. Images PMID:2471692

Tritrichomonas foetus was described as a commensal of the stomach, caecum and nasal cavity of pigs before it was recognised as the cause of reproductive tract disease of cattle. T. foetus also causes chronic large bowel diarrhoea in domestic cats. Multi-locus genotyping and comparative transcriptome analysis has previously revealed that T. foetus isolated from cat and cattle hosts are genetically distinct, referred to as the 'feline genotype' and 'bovine genotype', respectively. Conversely, multi-locus genotyping has grouped porcine T. foetus with the 'bovine genotype'. To compare the extent of the similarity between porcine T. foetus and cattle 'bovine genotype' isolates, RNA-sequencing (RNA-seq) was used to produce the first cell-wide transcriptome library of porcine T. foetus PIG30/1. Comparative transcriptome analysis of the PIG30/1 with the published bovine (BP-4) and feline (G10/1) transcriptomes revealed that the porcine T. foetus shares a 4.7 fold greater number of orthologous genes with the bovine T. foetus than with the feline T. foetus. Comparing transcription of the virulence factors, cysteine proteases (CP) between the three isolates, the porcine T. foetus was found to preferentially transcribe CP8 like the 'bovine genotype' T. foetus, compared to thehigh transcription of CP7 seen for 'feline genotype' T. foetus. At the cell-wide transcriptome level, the porcine T. foetus isolate (PIG30/1) groups closer with the 'bovine genotype' T. foetus rather than the 'feline genotype' T. foetus.

The aim of this study was to estimate the presence of Torque teno sus virus (TTV) species in pig foetuses in order to assess the possible relationship between swine TTV infection and abortion in swine. A total of 98 abortion cases and foetuses collected from 55 pregnant sows at slaughterhouse were analysed by PCR for the presence of Torque teno sus virus 1 (TTV1) and Torque teno sus virus 2 (TTV2). All foetuses were necropsied and relevant tissues were collected, pooled, and submitted to DNA extraction. The overall prevalence of swine TTV1 and TTV2 in aborted foetuses (n = 98) was 17.0% and 29.6%, respectively. For slaughterhouse collected foetuses (n = 55), 10.9% were TTV1 PCR positive and 40.0% were positive for TTV2. There were no statistically significant differences when comparing prevalence of swine TTVs by type of sample (aborted versus slaughterhouse collected foetuses) or by gestation stage. The present work represents the first description of swine TTV infection in pig foetuses at different stages of gestation. Results obtained confirm that vertical transmission is an important route of TTVs dissemination. In addition, data obtained suggest that swine TTVs should not be considered as infectious agents responsible for abortion occurrence.

Tritrichomonas foetus is a serious veterinary pathogen, causing bovine trichomoniasis, a sexually transmitted disease leading to infertility and abortion. T. foetus infects the mucosal surfaces of the reproductive tract. Infection with T. foetus leads to apoptotic cell death of bovine vaginal epithelial cells (BVECs) in culture. An affinity-purified cysteine protease (CP) fraction yielding on sodium dodecyl sulfate-polyacrylamide gel electrophoresis a single band with an apparent molecular mass of 30 kDa (CP30) also induces BVEC apoptosis. Treatment of CP30 with the protease inhibitors TLCK (Nα-p-tosyl-l-lysine chloromethyl ketone) and E-64 [l-trans-epoxysuccinyl-leucylamide-(4-guanido)-butane] greatly reduces induction of BVEC apoptosis. Matrix-assisted laser desorption ionization-time-of-flight MALDI-TOF mass spectrometry analysis of CP30 reveals a single peak with a molecular mass of 23.7 kDa. Mass spectral peptide sequence analysis of proteolytically digested CP30 reveals homologies to a previously reported cDNA clone, CP8 (D. J. Mallinson, J. Livingstone, K. M. Appleton, S. J. Lees, G. H. Coombs, and M. J. North, Microbiology 141:3077-3085, 1995). Induction of apoptosis is highly species specific, since the related human parasite Trichomonas vaginalis and associated purified CPs did not induce BVEC death. Fluorescence microscopy along with the Cell Death Detection ELISAPLUS assay and flow cytometry analyses were used to detect apoptotic nuclear condensation, DNA fragmentation, and changes in plasma membrane asymmetry in host cells undergoing apoptosis in response to T. foetus infection or incubation with CP30. Additionally, the activation of caspase-3 and inhibition of cell death by caspase inhibitors indicates that caspases are involved in BVEC apoptosis. These results imply that apoptosis is involved in the pathogenesis of T. foetus infection in vivo, which may have important implications for therapeutic interference with host cell death that could alter

This article examines ethical issues on the rights and interests of the unborn foetus, an issue that remains highly contentious. Furthermore, it attempts to investigate how well the British legislation fits with the foetus and pregnant woman's rights and interests. "Pro-life" and "pro-choice" groups have provided extensive arguments for and against. One important theoretical issue rests on whether foetuses are human beings in the moral sense, in which all human beings have full and equal moral rights. What constitutes personhood is a matter of moral decision and is not one of scientific fact and thus it consists of all persons, rather than all genetically human entities. It is persons who invent moral rights and who are capable of respecting them. Legislators in Britain have sidestepped the ethical debate on abortion by opting for the pragmatic course of permitting abortion in a limited range of circumstances and thus the Abortion Act 1967 has failed to address the status of the foetus, or indeed the rights of any of the parties concerned. Thus, although the Act supports the interests of the foetus capable of free existence by lowering the foetal age to 24 weeks after which termination is not permissible, the legislators have accepted that the rights of the woman outweigh those of the foetus and if a woman's own life or health is in danger then even a late abortion is the best choice.

Bovine venereal trichomonosis caused by the flagellate Tritrichomonas foetus is a notifiable disease in Australia. While, T. foetus is pathogenic in both cattle and cats, it has long been established that the same T. foetus colonises the stomach, caecum and nasal cavity of pigs without apparent clinical significance. Multi-locus genotyping grouped the non-pathogenic porcine T. foetus with the pathogenic 'bovine genotype', rather than with the 'feline genotype' T. foetus. Bovine trichomonosis is now uncommon due to wide-spread use of artificial insemination, however, whether T. foetus remains prevalent in pigs where bovine trichomonosis has been eradicated remains unknown. We surveyed faecal samples from pigs farmed in close proximity with T. foetus-negative cattle. The Modified Diamond's Medium assay used were 77.4% (24/31) positive for trichomonads and 64.50% (20/31) were T. foetus-positive based on real-time PCR and conventional PCR. An axenic reference strain of T. foetus, designated PIG30/1 was established. In addition, a novel trichomonad ITS rDNA, PIG12, closely related to sequences from Trichomitus spp is reported. Multi-locus genotyping at nine loci matched PIG30/1 to the 'bovine genotype' T. foetus. In conclusion, cross-species transmission of T. foetus between pigs and cows from environmental exposure of T. foetus-contaminated pig faeces is unlikely. Domestic T. foetus-positive pigs possess a negligible risk of a successful T. foetus transmission event to cattle.

Bovine brucellosis is endemic in Egypt in spite of application of surveillance and control measures. An increase of abortions was reported in a Holstein dairy cattle herd with 600 animals in Damietta governorate in Egypt after immunisation with Brucella (B.) abortus RB51 vaccine. Twenty one (10.6%) of 197 vaccinated cows aborted after 3 months. All aborted cows had been tested seronegative for brucellosis in the past 3 years. B. abortus was isolated from four foetuses. Conventional biochemical and bacteriological identification and polymerase chain reaction (PCR) confirmed two B. abortus biovar (bv.) 1 smooth and two B. abortus rough strains. None of the B. abortus isolates were identified as RB51. Genotyping analysis by multiple locus of variable number tandem repeats analysis based on 16 markers (MLVA-16) revealed two different profiles with low genetic diversity. B. abortus bv1 was introduced in the herd and caused abortions.

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.

Trichomonas vaginalis and Tritrichomonas foetus are parasitic protists of the human and bovine urogenital tracts, respectively. Several studies have described the cytotoxic effects of trichomonads on urogenital tract epithelial cells. However, little is known about the host cell response against trichomonads. The aim of this study was to determine whether T. foetus and T. vaginalis stimulated the release of the cytokine interleukin (IL)-10 from cultured bovine epithelial cells. To characterise the inflammatory response induced by these parasites, primary cultures of bovine oviduct epithelial cells were exposed to either T. vaginalis or T. foetus. Within 12 h after parasite challenge, supernatants were collected and cytokine production was analysed. Large amounts of IL-10 were detected in the supernatants of cultures that had been stimulated with T. foetus. Interestingly, T. vaginalis induced only a small increase in the release of IL-10 upon exposure to the same bovine cells. Thus, the inflammatory response of the host cell is species-specific. Only T. foetus and not T. vaginalis induced the release of IL-10 by bovine oviduct epithelial cells.

We aimed to evaluate the effects of maternal nutrition (MN) and foetal sex on the intestinal development of bovine foetuses throughout different days of gestation (DG). Forty-four multiparous, dry Holstein × Gyr cows with average initial body weight of 480 ± 10 kg were fed the same diet of either restricted feeding at 1.15% of body weight (CO, n = 24) or fed ad libitum (overnourished, ON, n = 20). Six cows from CO group and five cows from ON group were slaughtered at 139, 199, 241 and 268 DG, and foetuses were necropsied to evaluate the intestinal development. The mass, length and density of foetal intestines were not affected by MN (p ≥ 0.260). An interaction between MN and DG was observed for the villi length of jejunum (p = 0.006) and ileum (p < 0.001). Villi length of jejunum and ileum was higher (p < 0.10) in foetuses from ON-fed cows than in foetuses from CO-fed cows at 139 DG. However, at 199 DG, the villi length of jejunum and ileum of foetuses from CO-fed cows was higher than in foetuses from ON-fed cows. Despite these differences, MN did not affect the villi length of jejunum and ileum at 268 DG (p > 0.10). Female foetuses had greater small intestine mass (p = 0.093), large intestine mass (p = 0.022), small intestine mass in proportion to body mass (p = 0.017) and large intestine mass in proportion to body mass (p < 0.001) than male foetuses. Female foetuses had also longer small intestine (p = 0.077) and greater small intestine density (p = 0.021) and villi length of jejunum (p = 0.001) and ileum (p = 0.010) than males. We conclude that MN affects the pathway for the development of foetal villi length throughout the gestation in bovine foetuses without changing the final villi length. Female foetuses had higher intestinal mass, density and villi length than males during the foetal phase in bovines.

Knowledge of congenital malformations and their causes in horses is generally sparse. Such conditions require more scientific attention to improve their diagnostics and inform prevention strategies. Here, a unique syndrome of bilateral oblique facial clefts (meloschisis), rudimentary eyes and hydrocephalus is reported in an equine foetus spontaneously aborted at gestation day 224. The cause of abortion was considered to be intrauterine death caused by umbilical cord torsions and subsequent compromised blood flow, but the aetiology of the malformation could not be determined. A detailed history, which includes exposure to a range of pharmaceutical compounds during the early stages of pregnancy, is provided and emphasizes the need for accurate recording of treatments in pregnant animals.

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

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.
Although a preference for sons is reportedly a universal phenomenon, in some Asian societies daughters are considered financial and cultural liabilities. Increasing availability of ultrasonography and amniocentesis has led to widespread gender screening and selective abortion of normal female foetuses in many countries, including India. Feminists have taken widely divergent positions on the morality of this practice. Feminists from India have strongly opposed it, considering it as a further disenfranchisement of females in their patriarchal society, and have agitated successfully for legislative prohibitions. Libertarian feminists on the other hand, primarily from the United States, have argued that any prohibition of the use of this technology is a curtailment of a woman's reproductive choices and a violation of her right to make autonomous decisions regarding procreation. Using India as an illustrative case, this paper argues that in the context of what prevails in some societies, an ethical argument that hinges on the principle of autonomy as understood in the West can be problematic. Furthermore, a liberal theoretical assumption that it is always better to have more rather than fewer choices may not hold up well against the realities of life for such women. Although feminists have little disagreement concerning substantive matters, it is in the area of strategy that differences of opinion have arisen, their moral reasoning and responses shaped by the culture, ethnicity, class and race to which they belong. A view that a single 'orthodox' feminism of any variety can embody the aspiration of all women reverts to the problematic issues in the evolution of the rationalistic, individualistic, 'male' ethics against which women have consistently raised objections.

Advances in defining the biology of epizootic bovine abortion (EBA), including identification of the etiologic agent, have been hampered by the inability to reproduce the disease with confidence. Experimental reproduction of EBA, by feeding the tick vector Ornithodoros coriaceus on susceptible pregnant heifers, is not reliable. The primary objectives of this study were to identify specific tissue(s) obtained from EBA-infected fetuses that could transmit the disease, and then utilize such an infectious challenge system to better define the pathogen, host immunity and geographic distribution of the agent. Described here is the ability to routinely reproduce EBA following inoculation of cryopreserved suspensions of homogenized thymus into susceptible pregnant heifers. This challenge system permitted experiments demonstrating the agent was non-filterable, inactivated upon sonication and susceptible to antibiotics. These findings suggest a prokaryotic microbe and represent a major advance in EBA research. Additional experiments demonstrated that inoculation of the cryopreserved EBA-infectious tissue into heifers, prior to breeding, conferred immunity. Furthermore, such immunized heifers were resistant to challenge with heterologous sources of infectious tissue, suggesting monovalent vaccine development might be feasible. Lastly, challenge studies employing animals from Central Nevada, an area considered free of EBA, demonstrated partial immunity, suggesting the pathogen, and possibly the disease, enjoy a broader distribution than previously thought.

The ability for protozoan parasites to tolerate pH fluctuations within their niche is critical for the establishment of infection and require the parasite to be capable of adapting to a distinct pH range. We used two host adapted Tritrichomonas foetus isolates, capable of infecting either the digestive tract (pH 5.3-6.6) of feline hosts or the reproductive tract (pH 7.4-7.8) of bovine hosts to address their adaptability to changing pH. Using flow cytometry, we investigated the pH tolerance of the bovine and feline T. foetus isolates over a range of physiologically relevant pH in vitro. Following exposure to mild acid stress (pH 6), the bovine T. foetus isolates showed a significant decrease in cell viability and increased cytoplasmic granularity (p-value < 0.003, p-value < 0.0002) compared to pH 7 and 8 (p-value > 0.7). In contrast, the feline genotype displayed an enhanced capacity to maintain cell morphology and viability (p-value > 0.05). Microscopic assessment revealed that following exposure to a weak acidic stress (pH 6), the bovine T. foetus transformed into rounded parasites with extended cell volumes and displays a decrease in viability. The higher tolerance for acidic extracellular environment of the feline isolate compared to the bovine isolate suggests that pH could be a critical factor in regulating T. foetus infections and host-specificity.

Genomic imprinting plays a very important role during development and its abnormality may heavily undermine the developmental potential of bovine embryos. Because of limited resources of the cow genome, bovine genomic imprinting, both in normal development and in somatic cell nuclear transfer (SCNT) cloning, is not well documented. DNA methylation is thought to be a major factor for the establishment of genomic imprinting. In our study, we determined the methylation status of differential methylated regions (DMRs) of four imprinted genes in four spontaneously aborted SCNT-cloned fetuses (AF). Firstly, abnormal methylation imprints were observed in each individual to different extents. In particular, Peg3 and MAOA were either seriously demethylated or showed aberrant methylation patterns in four aborted clones we tested, but Xist and Peg10 exhibited relatively better maintained methylation status in AF1 and AF4. Secondly, two aborted fetuses, AF2 and AF3 exhibited severe aberrant methylation imprints of four imprinted genes. Finally, MAOA showed strong heterogeneous methylation patterns of its DMR in normal somatic adult tissue, but largely variable methylation levels and relatively homogeneous methylation patterns in aborted cloned fetuses. Our data indicate that the aborted cloned fetuses exhibited abnormal methylation imprints, to different extent, in aborted clones, which partially account for the higher abortion and developmental abnormalities during bovine cloning.

Cattle are commonly infected with pathogenic leptospires, and similarly to rodents, they excrete the bacteria in their urine and can transmit the pathogen from animal to animal or animal to human. Thus, surveillance and monitoring systems for detection of new Leptospira serovars are important for the control of leptospirosis. Here, we report the isolation of a spirochete from a stillborn bovine foetus and its characterization by immunological and molecular techniques. A variable number tandem repeat profile using seven discriminatory primers identified the spirochete as belonging to species Leptospira interrogans serogroup Australis serovar Muenchen. A phenotypic analysis using monoclonal antibodies (mAbs) against leptospiral membrane-associated proteins confirmed the expression of important virulence and pathogenicity factors (LipL32 and LigBrep). Out of 120 reference sera tested, 22 positive (36.66%) and 9 negative (15%) also reacted with the new isolate. Furthermore, the serovar Muenchen isolate was virulent in hamster model. The animal inoculated developed acute lethal infection characterized by hepatic, pulmonary and renal lesions. Local isolates exhibited unique characteristics that differed from those of reference strains; therefore, isolation of leptospires is useful in the surveillance of local pathogenic serovars. In conclusion, the data obtained from this study can contribute to the epidemiological understanding and control of leptospirosis in southern Brazil.

Considering the poor facilities available for microbiological diagnosis in some countries where Brucella abortus is a frequent cause of bovine abortion, a study was conducted to determine if isolation of B. abortus from an aborted bovine fetus could be predicted from a detailed histological study of the formalized lung. Thirty-nine samples of B. abortus positive and 20 negative fetal samples were examined for the presence of 14 different pulmonary lesions. Differences in the frequency of observed lesions between the positive and negative groups, were determined by odds ratios and chi square statistic. The confidence of the prediction was calculated by means of the logistic computer model. The frequency of eight lung lesions was found to be significantly (p less than 0.05) different between the groups; nevertheless, these lesions were not specific enough to be able to incriminate B. abortus as the cause of abortion.

Chlamydophila abortus and Waddlia chondrophila cause abortion in ruminants. We investigated the role of Parachlamydia acanthamoebae in bovine abortion. Results of immunohistochemical analyses were positive in 30 (70%) of 43 placentas from which Chlamydia-like DNA was amplified, which supports the role of Parachlamydia spp. in bovine abortion.

Switzerland is officially free from bovine Tritrichomonas foetus. While bulls used for artificial insemination (AI) are routinely examined for this pathogen, bulls engaged in natural mating, as well as aborted fetuses, are only very sporadically investigated, indicating that the disease awareness for bovine tritrichomoniasis is low. Natural mating in cattle is becoming increasingly popular in Switzerland. Accordingly, a re-introduction/re-occurrence of T. foetus in cattle seems possible either via resurgence from a yet unknown bovine reservoir, or via importation of infected cattle. The low disease awareness for bovine tritrichomoniasis might favor an unnoticed re-establishment of T. foetus in the Swiss cattle population. The aim of our study was thus to search for the parasite, and if found, to assess the prevalence of bovine T. foetus in Switzerland. We included (1) bulls over two years of age used in natural mating and sent to slaughter, (2) bulls used for natural service in herds with or without fertility problems and (3) aborted fetuses. Furthermore, the routinely examined bulls used for AI (4) were included in this study. In total, 1362 preputial samples from bulls and 60 abomasal fluid samples of aborted fetuses were analyzed for the presence of T. foetus by both in vitro cultivation and molecular analyses. The parasite could not be detected in any of the samples, indicating that the maximal prevalence possibly missed was about 0.3% (95% confidence). Interestingly, in preputial samples of three bulls of category 1, apathogenic Tetratrichomonas sp. was identified, documenting a proof-of-principle for the methodology used in this study.

Tritrichomonas foetus is the causative agent of bovine trichomonosis, a sexually transmitted disease leading to infertility and abortion. A test based on loop mediated isothermal amplification (LAMP) targeting the 5.8S rDNA subunit was designed for the specific identification of T. foetus. The LAMP assay was validated using 28 T. foetus and 35 non-T. foetus trichomonads strains. It did not exhibit cross-reaction with closely related parasites commonly found in smegma cultures like Tetratrichomonas spp. and Pentatrichomonas hominis. Bovine smegma did not show interferences for the detection of the parasite and, the sensitivity of the method (4×10(3) CFU/mL, approximately 10 cells/reaction) was slightly higher than that found for PCR amplification with TFR3 and TFR4 primers. The LAMP approach has potential applications for diagnosis and control of T. foetus and, practical use for low skill operators in rural areas.

Rapid and precise diagnosis plays a pivotal role in implementing suitable control measures in natural field cases of bovine abortion due to infection with bovine herpesvirus (BHV)-1. In the present study, serology, virus isolation, histopathology, immunohistochemistry (IHC) and real-time polymerase chain reaction (PCR) for amplification of the gene encoding glycoprotein B were applied for diagnosis of infectious bovine rhinotracheitis (IBR) in cases of abortion. The seroprevalence of IBR in the population studied was 26.3% as determined by indirect enzyme-linked immunosorbent assay. BHV-1 abortions occurred between 4 and 8 months of gestation with an average gestational age of 6 months. Affected placentae showed necrosis of chorionic villi and of the endothelium of small villous blood vessels with characteristic intranuclear (IN) acidophilic inclusion bodies. Similar inclusions were also seen in most of the tissues examined. BHV-1 antigen was identified immunohistochemically in necrotic foci in the liver, the endothelium of placental blood vessels, the bronchial epithelium and hepatocytes. Lesions in the brain also had IN inclusion bodies that labelled positively by IHC. Eighteen samples (nine of stomach content, two of placental cotyledons, five of pooled fetal tissue and two of vaginal discharge) out of 84 tested were positive by real-time PCR for BHV-1.

Two pregnant cows aborted 11 and 18 days after Mycoplasma agalactiae subsp bovis was inoculated into the amniotic fluids. The placentas were retained. The fetuses (approx 100 and 150 days of age) were decomposed; M agalactiae subsp bovis was recovered from several tissues of the fetuses, the placentas, and fetal fluids. The same organism was given by intraperitoneal injection to 2 other pregnant (130 and 180 days, respectively) cows. At necropsy of the latter 36 days later, placentitis was severe; M agalactiae subsp bovis was recovered from the placentas of both cows and from the fetus of 1 cow. Control cows given sterile mycoplasma cultural medium by intraamnion or intraperitoneal injection did not abort and were not infected. When first recovered from the bovine placenta and fetus, M agalactiae subsp bovis grew slowly in liquid medium and assumed bizarre colonial morphology on solidified medium. Colonies were small (0.1 to 0.5 mm) and dark and lacked halos, but they reacted specifically in the direct fluorescent antibody test with equine M agalactiae subsp bovis antiserum. After 1 or 2 subcultures, the isolates grew at a normal rate and displayed their usual colonial morphology.

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.

Brucellosis is a reemerging infectious zoonotic disease of worldwide importance. In human, it is mainly caused by Brucella melitensis, a natural pathogen for goats. In India, a large number of goats are reared in semi-intensive to intensive system within the close vicinity of human being. At present, there is no vaccination and control strategy for caprine brucellosis in the country. Thus, to formulate an effective control strategy, the status of etiological agent is essential. To cope up with these, the present study was conducted to isolate and identify the prevalent Brucella species in caprine brucellosis in India. The 30 samples (fetal membrane, fetal stomach content and vaginal swabs) collected throughout India from the aborted fetus of goats revealed the isolation of 05 isolates all belonging to Brucella melitensis biovars 3. All the isolates produced amplification products of 1412 and 720 bp in polymerase chain reaction with genus and species specific 16S rRNA and omp31 gene based primers, respectively. Moreover, the amplification of omp31 gene in all the isolates confirmed the presence of immuno dominant outer membrane protein (31 kDa omp) in all the field isolates of B. melitensis in aborted foetus of goats in India. These findings can support the development of omp31 based specific serodiagnostic test as well as vaccine for the control of caprine brucellosis in India.

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.

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

Tritrichomonas foetus infects the bovine urogenital tract, causing bovine trichomoniasis. Significant economic losses may occur due to infertility and abortion among cattle. Trichomonas vaginalis is the causative agent of trichomoniasis; the most common but overlooked non-viral sexually transmitted disease worldwide. Human and bovine trichomoniasis present treatment restrictions and efforts to identify new alternatives are essential. The present study evaluated the anti-trichomonads activities of seven fractions from northwest endemic plant Manilkara rufula. Flavonoids and condensed tannins were identified from these fractions by LC-DAD-MS/MS and MALDI-MS/MS. Altogether, the results demonstrated for the first time the structural description of tannins from leaves of M. rufula and the relation of these compounds with anti-T. vaginalis and anti-T. foetus activities. Overall, this report reveals the potential of M. rufula fractions against both parasites and shows new alternatives to treat the infection caused by trichomonads.

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

The effect of spontaneous abortion on the dairy industry is substantial, costing the industry on the order of US dollars 200 million per year in California alone. We analyse data from a cohort study of nine dairy herds in Central California. A key feature of the analysis is the observation that only a relatively small proportion of cows will abort (around 10;15 per cent), so that it is inappropriate to analyse the time-to-abortion (TTA) data as if it were standard censored survival data, with cows that fail to abort by the end of the study treated as censored observations. We thus broaden the scope to consider the analysis of foetal lifetime distribution (FLD) data for the cows, with the dual goals of characterizing the effects of various risk factors on (i). the likelihood of abortion and, conditional on abortion status, on (ii). the risk of early versus late abortion. A single model is developed to accomplish both goals with two sets of specific herd effects modelled as random effects. Because multimodal foetal hazard functions are expected for the TTA data, both a parametric mixture model and a non-parametric model are developed. Furthermore, the two sets of analyses are linked because of anticipated dependence between the random herd effects. All modelling and inferences are accomplished using modern Bayesian methods.

The prevalence of cattle seropositive to bovine herpesvirus-4 (BHV-4) is high in Belgium. In Belgian farms, clinical signs associated with BHV-4 infection essentially involve the genital tract and consist mainly of postpartum metritis or metroperitonitis. The role of BHV-4 in abortion has not been definitively demonstrated but epidemiological and experimental facts suggest its involvement. A seroepidemiological investigation was therefore conducted as a case-control study to compare the seroprevalences of BHV-4 infections in the aborted-cow population and in a randomly selected control group in the province of Liège (Belgium). The seroprevalence (17.2%) in aborted cows was significantly higher than that of the control group (10.0%). The odds ratio (OR) was 1.87 (1.06 < 3.30). BHV-4 infection is therefore considered as a risk factor for abortion in cows.

High rate of abortion and developmental abnormalities is thought to be closely associated with inefficient epigenetic reprogramming of the transplanted nuclei during bovine cloning. It is known that one of the important mechanisms for epigenetic reprogramming is DNA methylation. DNA methylation is established and maintained by DNA methyltransferases (DNMTs), therefore, it is postulated that the inefficient epigenetic reprogramming of transplanted nuclei may be due to abnormal expression of DNMTs. Since DNA methylation can strongly inhibit gene expression, aberrant DNA methylation of DNMT genes may disturb gene expression. But presently, it is not clear whether the methylation abnormality of DNMT genes is related to developmental failure of somatic cell nuclear transfer embryos. In our study, we analyzed methylation patterns of the 5' regions of four DNMT genes including Dnmt3a, Dnmt3b, Dnmt1 and Dnmt2 in four aborted bovine clones. Using bisulfite sequencing method, we found that 3 out of 4 aborted bovine clones (AF1, AF2 and AF3) showed either hypermethylation or hypomethylation in the 5' regions of Dnmt3a and Dnmt3b, indicating that Dnmt3a and Dnmt3b genes are not properly reprogrammed. However, the individual AF4 exhibited similar methylation level and pattern to age-matched in vitro fertilized (IVF) fetuses. Besides, we found that the 5' regions of Dnmt1 and Dnmt2 were nearly completely unmethylated in all normal adults, IVF fetuses, sperm and aborted clones. Together, our results suggest that the aberrant methylation of Dnmt3a and Dnmt3b 5' regions is probably associated with the high abortion of bovine clones.

Postmortem examinations were performed on 30 morphologically abnormal aborted bovine fetuses, stillbirths and nonviable neonates. Fibroblasts from the pericardium were cultured for chromosome analysis. Karyotypes were successfully completed on 18 animals, of which three were trisomic, one was mosaic monosomic and one was chimeric. All aneuploid calves had multisystemic anomalies. Using chromosomal banding techniques, the abnormal karyotypes were determined to be: 61,XY,+27; 61,XX,+21; 61,XY,+?; 59,XY,-?/60,XY; and 60,XX/60,XY. Bacterial contamination or nonviability of tissues prevented the growth of fibroblasts in culture and cytogenetic analysis of the other 12 animals. It was estimated that 2.0% of all late gestation abortuses and stillbirths may have chromosomal abnormalities characterized by aneuploidy. The findings of this study suggest chromosomal abnormalities characterized by aneuploidy are a significant cause of multisystemic anomalies in aborted bovine fetuses and nonviable neonates.

An abortion is a procedure to end a pregnancy. It uses medicine or surgery to remove the embryo or ... personal. If you are thinking of having an abortion, most healthcare providers advise counseling.
The Alan Guttmacher Institute's State Reproductive Health Monitor "Legislative Proposals and Actions" provides US legislative information on abortion. The listing contains information on pending bills: the state, the identifying legislative number, the sponsor, the committee, the date the bill was introduced, a description of the bill, and when available the bill's status. The bills cover: 1) clinic licensing, e.g., requiring outpatient health care facilities in which abortions are performed, to have malpractice liability insurance; 2) comprehensive statues, which require parental notification before minor may obtain abortions, mandate abortion counseling to all women 24 hours before the abortion can be performed and prohibit disciplining or discharging a state employee for refusing to provide abortion counseling; 3) fetal personhood and rights, e.g. providing that life is vested in each person at fertilization; 4) fetal research and remains; 5) gender of fetus, which regulate abortions relative to sex selection in pregnancies; 6) harassment regulation; 7) informed consent and waiting periods detailing the risks and alternatives to abortion, and the 24-hour waiting period; 8) insurance coverage, e.g., eliminating language banning the coverage of abortions for state workers, and prohibiting disclosure by a health insurance carrier to the employer of a claimant that the claimant had a surgical abortion; 9) legality of abortion, urging Congress to reject he Freedom of Choice Act; 10) parental consent and notification; 11) postviability requirements; 12) public funding; 13) reporting requirements; 14) reproductive rights, and 15) spousal and paternal consent and notification.

The protozoan parasite Tritrichomonas foetus is well known as an important causative agent of infertility and abortion in cattle (bovine trichomonosis). This World Organisation for Animal Health (O.I.E.) notifiable disease is thought to be under control in many countries including Switzerland. In recent studies, however, T. foetus has also been identified as an intestinal parasite that causes chronic large-bowel diarrhoea in cats. Since the feline isolates were considered indistinguishable from bovine isolates, the possibility and risk of parasite transmission from cats to cattle and vice versa has been intensively discussed in current literature. Therefore, we investigated if cat and cattle isolates are genetically distinct from each other or in fact represent identical genotypes. For this purpose, two independent genetic loci were selected that turned out to be well-suited for a PCR sequencing-based genotyping of trichomonad isolates: (i) previously published internal transcribed spacer region 2 (ITS-2) and (ii) a semi-conserved sequence stretch of the elongation factor-1 alpha (EF-1α) gene used for the first time in the present study. Respective comparative analyses revealed that both loci were sufficiently variable to allow unambiguous genetic discrimination between different trichomonad species. Comparison of both genetic loci confirmed that T. suis and T. mobilensis are phylogenetically very close to T. foetus. Moreover, these two genetic markers were suited to define host-specific genotypes of T. foetus. Both loci showed single base differences between cat and cattle isolates but showed full sequence identity within strains from either cat or cattle isolates. Furthermore, an additional PCR with a forward primer designed to specifically amplify the bovine sequence of EF-1α was able to discriminate bovine isolates of T. foetus from feline isolates and also from other trichomonads. The implications these minor genetic differences may have on the biological

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.

A survey of 886 adults over 16 was conducted regarding abortion in Papanui, New Zealand. Only 7.79% thought a person should never have an abortion under any circumstances, 16.70% thought the decision to have an abortion should be decided by a panel of two doctors, a social worker, and a statutory committee set up by the government. 44.4% thought the decision should be between a woman and the doctor of her choice. 20.54% thought the decision should be made solely by the woman concerned. The respondants had thought about the question. Other surveys in different electorates reflected similar views. It is hoped that people's opinions will influence legislators to enact more liberal abortion laws.
Background Lichtheimia corymbifera (previously Absidia corymbifera) is a filamentous zygomycetes belonging to the order Mucorales and to the family Lichtheimiaceae. Members of genus Lichtheimia spp. are cosmopolitan and ubiquitous in nature. Lichtheimia corymbifera is a recognized agent of diseases in man and animals. In cattle it causes abortion and mastitis. Three cases of bovine abortion occurred in a herd located in the Po Valley. Serological examinations were performed on fetal and mother's blood. One of the aborted fetus was referred to our laboratory. The paper describes the isolation and characterization of Lichtheimia corymbifera from a bovine aborted fetus. Methods Serological examinations were performed on fetal and mother's blood. Lesions on fetal tissues and placenta leaded the diagnostic suspect towards a mycotic aetiology. Tissues were then put in culture, and at the same time an histological examination was performed, together with bacteriological and virological tests. The isolate from placenta and fetal tissues was identified and characterized by PCR and RFLP, using the ITS region as a target sequence and AclI restriction site within the amplicon to distinguish Lichtheimia corymbifera among the other fungi. Results Serological, bacteriological and virological tests gave aspecific results. Histological examination evidenced numerous PAS positive hyphae within the necrotic cotiledons and numerous fungal nonseptate hyphae to the GMS stain. Colonies with typical morphological features of fungi grew up on Sabouraud agar from fetal skin and placenta. On the developed colonies the microscopic examination has shown a large number of nonseptate hyphae and sporangia consistent with Mucorales. PCR and RFLP allowed the identification of the isolate as Lichtheimia corymbifera. Conclusion The present report describes the isolation and the molecular characterisation of a fungal isolate from bovine aborted fetus and placenta. The diagnostic protocol allowed to

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

Epizootic bovine abortion (EBA), a tick-transmitted disease of pregnant cattle grazing foothill pastures, is a major cause of reproductive failure in California and adjacent states. Affected fetuses develop a chronic disease, resulting in late-term abortion or premature calving. Despite investigations spanning 50 years, to the authors' knowledge, the etiologic agent of EBA has not yet been isolated from affected fetuses or the tick vector. The diagnosis of EBA is based on gross and microscopic lesions. Recently, documentation that the etiologic agent is susceptible to antibiotics and identification of a unique 16S deltaproteobacterial rDNA gene sequence in 90% of thymus tissues from aborted fetuses have supported the role of a bacterial infection as the cause of EBA. To determine whether bacteria could be detected in the tissues, histochemical staining and immunohistochemical procedures were used on formalin-fixed, paraffin-embedded tissues. Use of a modified Steiner silver stain revealed small numbers of intracytoplasmic bacterial rods in 37 of 42 thymic samples from EBA-affected fetuses. Improved detection was achieved by use of immunohistochemical staining with serum from EBA-affected fetuses that resulted in detection of numerous bacterial rods in the cytoplasm of histiocytic cells in the thymus from all 42 EBA-affected fetuses. Immunohistochemical examination of additional tissues from 21 field and experimental EBA cases revealed positively stained intracytoplasmic bacterial rods in many organs with inflammatory lesions. Use of the modified Steiner stain and immunohistochemical staining of tissues from negative-control fetuses failed to reveal organisms. To the authors' knowledge, this is the first report to document morphologic evidence of a bacterium associated with the lesions of EBA.

Campylobacter (C.) fetus (epsilonproteobacteria) is an important veterinary pathogen. This species is currently divided into C. fetus subspecies (subsp.) fetus (Cff) and C. fetus subsp. venerealis (Cfv). Cfv is the causative agent of bovine genital Campylobacteriosis, an infectious disease that leads to severe reproductive problems in cattle worldwide. Cff is a more general pathogen that causes reproductive problems mainly in sheep although cattle can also be affected. Here we describe a multiplex PCR method to detect C. fetus and differentiate between subspecies in a single step. The assay was standardized using cultured strains and successfully used to analyze the abomasal liquid of aborted bovine fetuses without any pre-enrichment step. Results of our assay were completely consistent with those of traditional bacteriological diagnostic methods. Furthermore, the multiplex PCR technique we developed may be easily adopted by any molecular diagnostic laboratory as a complementary tool for detecting C. fetus subspecies and obtaining epidemiological information about abortion events in cattle.

At some point in the future - perhaps within the next few decades - it will be possible for foetuses to develop completely outside the womb. Ectogenesis, as this technology is called, raises substantial issues for the abortion debate. One such issue is that it will become possible for a woman to have an abortion, in the sense of having the foetus removed from her body, but for the foetus to be kept alive. We argue that while there is a right to an abortion, there are reasons to doubt that there is a right to the death of the foetus. Our strategy in this essay is to consider and reject three arguments in favour of this latter right. The first claims that women have a right not to be biological mothers, the second that women have a right to genetic privacy, and the third that a foetus is one's property. Furthermore, we argue that it follows from rejecting the third claim that genetic parents also lack a right to the destruction of cryopreserved embryos used for in vitro fertilization. The conclusion that a woman possesses no right to the death of the foetus builds upon the claims that other pro-choice advocates, such as Judith Jarvis Thomson, have made.

Foetus-in-fetu is a rare condition in which a calcified mass is in the abdomen of its host, a newborn or an infant. We report a case of a newborn in whom abdominal radiograph and ultrasonography revealed a mass in which the contents favour a foetus-in-fetu. Diagnosis was confirmed by macroscopic examination that showed a soft tissue mass resembling a foetus, attached to the membranous sac. It was covered entirely with intact skin. There were two malformed lower limbs with a rudimentary digit and one malformed upper limb.

Bovine trichomonosis caused by Tritrichomonas foetus is a significant reproductive disease of cattle. Preputial samples were collected using sheath washing technique in bulls in Namibia. Thirty-six trichomonad cultures were characterized using the TaqMan-probe commercial real-time polymerase chain reaction (PCR) diagnostic assay (VetMAX™-Gold Trich Detection Kit) and CYBR real-time PCR assay based on TFR3/4 primers. Diagnostic real-time PCRs and DNA sequencing of the internal transcribed region confirmed presence of T. foetus in 35 out of 36 samples. Multilocus genotyping using cysteine proteases (CP1, CP2, CP4, CP5, CP6, CP7, CP8, CP9) and malate dehydrogenase (MDH1) gene sequences demonstrate that the T. foetus in Namibia are genetically distinct from those characterized elsewhere. We report the discovery of a novel genotype of T. foetus in Namibian cattle, distinct from other T. foetus genotypes in Europe, South and North America and Australia. We suggest recognition of a 'Southern African' genotype of T. foetus. Identification of the new genotype of T. foetus demonstrates the need for wider global sampling to fully understand the diversity and origin of T. foetus causing disease in cattle or cats.
Professor Judith Jarvis Thomson's seminal paper "A defence of abortion" published in 1971 has formed part of higher education syllabi for decades. In the paper Thomson criticizes one of the fundamental arguments against abortion, that is, the right of the foetus to life by denying that the foetus is a person. This article argues that her thought experiments do not compare to the reality of abortion and focuses on the influence of the paper on arguments concerning personhood.

Bovine trichomoniasis has been recognized as a pathogen of the bovine reproductive tract for nearly 100 years. Although characteristics of the causative organism, Tritrichomonas foetus lend to control and there are examples of disease eradication, cattle producers are still faced with this disease. This article highlights the clinical presentation, magnitude of effect, risk factors, epidemiology, and sample collection and suggests applications in developing herd-level control measures for beef cattle producers including testing strategies for control, testing strategies for surveillance, strategies to eliminate trichomoniasis from infected herds, and strategies for prevention in uninfected herds.
Background Since 2005, France has been officially free of brucellosis, an infectious disease that causes abortion in cattle and can be transmitted from cattle to humans. Recent animal and human cases have drawn attention to the need to prevent infection of humans and animals from any primary outbreaks. In order to detect any new outbreaks as soon as possible, a clinical surveillance system requires farmers and veterinarians to report each abortion and to test the aborting cow for brucellosis. However, under-reporting limits the sensitivity of this system. Our objective was to identify the barriers and motivations influencing field actors in their decision to report or not to report bovine abortions. We used a qualitative approach with semi-structured interviews of 12 cattle farmers and their eight veterinarians. Results Our analysis showed that four main themes influence the decision-making process of farmers and veterinarians: 1) the perceived risk of brucellosis and other abortive diseases; 2) the definition of a suspected case of brucellosis and other abortive diseases adopted by field actors, which is less sensitive than the mandatory definition; 3) the cost-benefit analysis conducted by actors, taking into account regulatory and health aspects, economic and financial losses, technical and practical factors; 4) the level of cooperation within the socio-technical network. We discussed how early detection may be improved by revising the definition of abortion, extending the time frame for notification and generalising the differential diagnosis of the causes of abortion. Conclusions In contrast to quantitative approaches, qualitative studies can identify the factors (including unknown factors) influencing the decision-making process of field actors and reveal why they take those factors into consideration. Our qualitative study sheds light on the factors underlying the poor sensitivity of clinical brucellosis surveillance system for cattle in France, and suggests

Foetus-in-foetu is a rare malformation in which a monozygotic diamniotic parasitic twin is incorporated into the body of its fellow twin and grows inside it. Less than 100 cases have been reported in literature. One day old newborn male was admitted with antenatal diagnosis of abdominal mass. It was cystic/solid in nature with pressure effects on left ureter and urinary bladder, most likely to be a germ cell tumour. Birth history was uneventful. Exploratory laparotomy was performed and the mass was excised. Physical examination confirmed the diagnosis of foetus-in-foetu. Although it is a rare condition, imaging may play an important role in the correct prospective diagnosis of foetus-in-foetu. Surgical excision is the recommended treatment.

The traditional approach to the abortion debate revolves around numerous issues, such as whether the foetus is a person, whether the foetus has rights, and more. Don Marquis suggests that this traditional approach leads to a standoff and that the abortion debate 'requires a different strategy.' Hence his 'future of value' strategy, which is summarized as follows: (1) A normal foetus has a future of value. (2) Depriving a normal foetus of a future of value imposes a misfortune on it. (3) Imposing a misfortune on a normal foetus is prima facie wrong. (4) Therefore, depriving a normal foetus of a future of value is prima facie wrong. (5) Killing a normal foetus deprives it of a future value. (6) Therefore, killing a normal foetus is prima facie wrong. In this paper, I argue that Marquis's strategy is not different since it involves the concept of person--a concept deeply rooted in the traditional approach. Specifically, I argue that futures are valuable insofar as they are not only dominated by goods of consciousness, but are experienced by psychologically continuous persons. Moreover, I argue that his strategy is not sound since premise (1) is false. Specifically, I argue that a normal foetus, at least during the first trimester, is not a person. Thus, during that stage of development it is not capable of experiencing its future as a psychologically continuous person and, hence, it does not have a future of value.

The purpose of this study was to use mixed logistic regression to evaluate the association between Neospora caninum serostatus and abortion, accounting for the effects of farms. The main objective was to explore the interpretation of this model and discuss the contribution of this analysis to our understanding of the disease's epidemiology. A mixed-effects logistic model using farms as a random effect and the serostatus for N. caninum, age of cattle and farm location as fixed effects was performed. The data from 1256 cows over 15 months of age from 60 farms were used, and the abortion information was obtained from farm records. A significant association between N. caninum serostatus and abortion was found (p<0.0001). Seropositive cows had 6.63 times greater odds of having a history of previous abortion (95% CI: 4.35-13.37). There was remarkable variability across farms in the probability of a cow having a history of an abortion. Including the effects of the farms in the regression, it was possible to estimate an intraclass correlation coefficient (ICC) of 16%. That means that 16% of the variation in abortion occurrence that was not explained by the fixed effects was due to farms. In practical terms, this variation means that while there are farms with several seropositive cows and no/few abortion cases, the opposite is also true, with a high number of abortions in farms with low/medium seroprevalence. The remaining variability (84%) was not explained by the effect of N. caninum, age, region, and the effect of farms, i.e., it is due to unknown factors that are causing abortions. The results of this study reinforce the importance of N. caninum as a cause of abortions and demonstrate the significant heterogeneity in the probability of a cow having a history of an abortion that cannot be explained completely by N. caninum serostatus, age or location. Including the hierarchical structure of the population along with correct interpretation of the model estimates helps us

Trichomonads are obligate protozoan parasites most renowned as venereal pathogens of the reproductive tract of humans and cattle. Recently, a trichomonad highly similar to bovine venereal Tritrichomonas foetus but having a unique tropism for the intestinal tract was recognized as a significant cause of colitis in domestic cats. Despite a high prevalence, worldwide distribution, and lack of consistently effective drugs for treatment of the infection, the cellular mechanisms of T. foetus pathogenicity in the intestinal tract have not been examined. The aims of this study were to determine the pathogenic effect of feline T. foetus on porcine intestinal epithelial cells, the dependence of T. foetus pathogenicity on adhesion of T. foetus to the intestinal epithelium, and the identity of mediators responsible for these effects. Using an in vitro coculture approach to model feline T. foetus infection of the intestinal epithelium, these studies demonstrate that T. foetus promotes a direct contact-dependent activation of intestinal epithelial cell apoptosis signaling and progressive monolayer destruction. Moreover, these pathological effects were demonstrated to be largely dependent on T. foetus cell-associated cysteine protease activity. Finally, T. foetus cysteine proteases were identified as enabling cytopathic effects by promoting adhesion of T. foetus to the intestinal epithelium. The present studies are the first to examine the cellular mechanisms of pathogenicity of T. foetus toward the intestinal epithelium and support further investigation of the cysteine proteases as virulence factors in vivo and as potential therapeutic targets for ameliorating the pathological effects of intestinal trichomonosis.

Bovine herpesvirus 1 (BoHV-1) is 1 of several viruses considered to be causal agents of bovine abortion. The current retrospective study examined data on bovine abortion submissions from 5 veterinary diagnostic laboratories from 2000 to 2011. The objective of the study was to describe prevalence of BoHV-1-associated abortion in submissions at veterinary diagnostic laboratories. There were 3 specific aims: 1) to examine the proportion of BoHV-1-related abortions with the introduction of new diagnostic assays such as polymerase chain reaction (PCR), 2) to evaluate the agreement of the histopathology report of the abortion submissions and the result of the assay used, and 3) to evaluate if there was an association between farm history of vaccination against BoHV-1 and BoHV-1-positive abortion submissions. An extended Mantel-Haenszel χ(2) for linear trend was used to analyze the prevalence of BoHV-1 over the study period and showed that collectively there is evidence of an increase of positive BoHV-1 abortions (P < 0.001). The comparison of the proportion of BoHV-1-positive submissions pre- and postadoption of PCR was not significant (P = 0.25). Using Cohen kappa coefficient test of agreement, a kappa value of 0.81 (P < 0.001) was found, suggesting high agreement of lesions reported and assay result. It was found that using a χ(2) test, a P value of 0.068 for nonmatched data (i.e., a history of vaccination against BoHV-1 in the herd) was associated with reduced detection of BoHV-1-positive abortion submissions.

Tritrichomonas foetus is a venereal pathogen of cattle, which causes infertility, early embryonic death or abortion. In order to evaluate the potential trichomonicidal activity of benzimidazoles, the effects of thiabendazole, mebendazole and albendazole were analyzed on the multiplication, general morphology and ultrastructure of T. foetus. It was found that mebendazole presented the highest IC(50%) (2.3 microM), when compared with albendazole (IC(50%)=9.4 microM) and thiabendazole (IC(50%)=142.6 microM), and that such effects were irreversible. Concerning microscopic analysis, thiabendazole- and mebendazole-treated cells presented increased volume, internalization of the flagella, disruption or multiplication of the nucleus, multiple organelles and cytoplasmic vacuolization. Albendazole-treated cells exhibited slight alterations, because the parasite became slightly rounded, its flagella were not internalized but the cytoplasm was vacuolated. Mebendazole was indeed highly effective as an in vitro trichomonicidal agent, and this might open up new possibilities for the use of mebendazole in the therapy of bovine trichomoniasis.

The current study describes the development of a set of 5 multiplex polymerase chain reaction (mPCR) assays for the simultaneous detection of abortive infection agents in bovine fetal tissues, including Brucella spp., Leptospira spp., and Campylobacter fetus (mPCR1); Hammondia heydorni, Neospora caninum, and Toxoplasma gondii (mPCR2); Coxiella burnetii and Chlamydophila psittaci (mPCR3); Mycoplasma bovis, Mycoplasma bovigenitalium, and Ureaplasma diversum (mPCR4); and Bovine viral diarrhea virus (BVDV) and Bovine herpesvirus-1 (BoHV-1; mPCR5). The protocol was tested on different tissue samples collected from 50 aborted bovine fetuses, and it showed that out of the 50 fetuses, 7 (14%, mPCR2) were PCR-positive for N. caninum, 4 (8%, mPCR5) were PCR-positive for BVDV, and 2 (4%, mPCR4) were PCR-positive for U. diversum. The results obtained by using each multiplex PCR were 100% concordant with those obtained by using the respective PCR assays targeting single genes on the same specimens. Moreover, all multiplex PCR assays on clinical samples were compared with reference methods, obtaining a perfect accordance in all samples and confirming the validity of the set of multiplex PCR assays. The proposed set of multiplex PCR assays is, therefore, suitable for the simultaneous detection of the main infectious agents responsible for bovine abortion.

Tritrichomonas foetus is a flagellated protozoan that causes a sexually transmitted disease in cattle. Trichomonosis is characterized by early abortions, subfertility and a significant decrease in productivity. Vaccine preparations containing whole T. foetus can reduce the time of residence of the pathogen in the host cervix after experimental infection. Here, T. foetus vaccines prepared with different adjuvants were tested, in parallel with a commercial vaccine, for their efficacy to clear the infection. The median time for clearance of infection was 69days in non-immunized animals, 55days in animals treated with aluminum hydroxide, 41days with oil-in-water or saponin based vaccines or with a commercial vaccine and 27days in animals treated with saponin plus aluminum hydroxide. A slight increase in the risk of T. foetus clearance from the genital tract was found with the saponin based vaccine (hazard ratio, 2.52; 95% confidence interval, 1.03-6.17) or the commercial vaccine (hazard ratio, 2.61; 95% confidence interval, 1.07-6.38). A significant increase in the risk of T. foetus clearance was found with the combination of saponin plus aluminum hydroxide based vaccine (hazard ratio, 5.12; 95% confidence interval, 2.04-12.83).

Genomics experiments are widely acknowledged to produce a huge amount of data to be analysed. The challenge is to extract meaningful biological context for proteins or genes which is currently difficult because of the lack of an integrative workflow that hinders the efficiency and the robustness of data mining performed by biologists working on ruminants. Thus, we designed ProteINSIDE, a free web service (www.proteinside.org) that (I) provides an overview of the biological information stored in public databases or provided by annotations according to the Gene Ontology, (II) predicts proteins that are secreted to search for proteins that mediate signalisation between cells or tissues, and (III) analyses protein-protein interactions to identify proteins contributing to a process or to visualize functional pathways. Using lists of proteins or genes as a unique input, ProteINSIDE is an original all-in-one tool that merges data from these searches to present a fast overview and integrative analysis of genomic and proteomic data from Bovine, Ovine, Caprine, Human, Rat, and Murine species. ProteINSIDE was bench tested with 1000 proteins identifiers from each species by comparison with DAVID, BioMyn, AgBase, PrediSi, and Phobius. Compared to DAVID or BioMyn, identifications and annotations provided by ProteINSIDE were similar from monogastric proteins but more numerous and relevant for ruminants proteins. ProteINSIDE, thanks to SignalP, listed less proteins potentially secreted with a signal peptide than PrediSi and Phobius, in agreement with the low false positive rate of SignalP. In addition ProteINSIDE is the only resource that predicts proteins secreted by cellular processes that do not involve a signal peptide. Lastly, we reported the usefulness of ProteINSIDE to bring new biological hypotheses of research from proteomics data: the biological meaning of the uptake of adiponectin by the foetal muscle and a role for autophagy during ontogenesis of adipose and muscle

Tritrichomonas foetus is a sexually transmitted protozoon that causes genital inflammation and adverse pregnancy outcomes in cattle. Cysteine proteinases (CPs) released by T. foetus degrade immunoglobulin G (IgG) antibodies, complement component 3 and matrix proteins as well as inducing apoptosis of bovine genital epithelial cells. In this study, the efficacies of the vinyl sulfone CP inhibitors K11777 and WRR-483 were tested against CPs of T. foetus. The activity of secreted T. foetus CPs in culture supernatants was decreased in the presence of vinyl sulfone inhibitors. Inhibitor K11777 reduced the in vitro cytopathogenic effects of T. foetus in bovine foetal trophoblast cells, which are relevant target cells since this pathogen interferes with pregnancy. Pre-treatment of T. foetus prior to intravaginal inoculation diminished genital infection in a murine model. Therefore, vinyl sulfone CP inhibitors reduce several effects of T. foetus-secreted CPs, including cytotoxicity on relevant target host cells and genital infection in a murine model. These inhibitors have potential as chemotherapeutic agents against bovine trichomoniasis. Generalisation to human trichomoniasis requires further study.

Tritrichomonas foetus is a sexually transmitted reproductive pathogen of cattle that causes transient infertility, early embryonic death, metritis, pyometra, and sporadic abortions. The objective of this research was to assess the impact on reproductive health of vaccinating naïve heifers with a killed T. foetus vaccine (TrichGuard) before experimental exposure followed by breeding. A total of 40 beef heifers were randomly assigned into two treatment groups. Heifers where then vaccinated with two doses of TrichGuard or sham vaccinated with 0.9% sterile saline according to their respective groups. Sixty days following vaccination or sham vaccination, heifers were intravaginally inoculated with 2 × 10(6) organisms of a cloned isolate of T. foetus of bovine origin (CDTf-4) during synchronized estrus. Three days following inoculation of T. foetus, bulls free of T. foetus were introduced for natural breeding. Three bulls were maintained with the 40 heifers (20 vaccinated; 20 sham vaccinated) for a 49-day breeding season. Cervical mucous samples were obtained from each heifer at Day 0 and at 29 additional time points throughout the study for T. foetus culture. Pregnancy assessments were performed routinely by using transrectal palpation and ultrasonography. Pregnancies were detected in 19/20 (95%) vaccinated heifers and 14/20 (70%) sham-vaccinated heifers (P = 0.046). Only 4/20 (20%) of the sham-vaccinated heifers gave birth to a live calf compared with 10/20 (50%) of the vaccinated heifers (P = 0.048). Thus, embryonic or fetal loss was detected in 9/19 (47%) vaccinated heifers and 10/14 (71%) sham-vaccinated heifers (P = 0.153). The interval of time between inoculations with T. foetus and conceptions of pregnancies that were maintained until birth did not differ significantly between groups (vaccinated = 18.7 days; sham-vaccinated = 17.3 days; P = 0.716). The infectious challenge in this study proved to be very rigorous as a positive culture was

Tritrichomonas foetus is a potent veterinary pathogen, causing bovine and feline trichomoniasis. The principal clinical manifestation of infection in cattle is inflammation of the genital tract and infertility. In feline, the parasite causes large-bowel disease resulting in chronic diarrhea. In contrast to other well-studied protozoan, genetic data regarding the molecular characterization and expression in T. foetus is far less understood. In this study, the first large-scale T. foetus expressed sequence tag (TfEST) project was conducted on 5064 randomly selected EST clones from a non-normalized unidirectional Tf30924 cDNA library. Assembling of 5064 single-pass sequences from the 5' end resulted in 713 contigs and 1961 singlets. BLAST search revealed that 53.52% of the unigenes showed significant similarity to known sequences or protein motifs/domains. Functional classifications indicated that most of the unigenes are involved in translation, ribosomal structure and ribosome biogenesis. The average GC content of the T. foetus transcriptome is 40.93%. Intriguingly, only 31.29% of the unigenes contain the classical AAUAAA polyadenylation signal sequence at the 3'-UTR region. Furthermore, a panel of potential chemotherapeutic targets was also identified for the first time in T. foetus. The protein expression levels were verified by using two-dimensional electrophoresis and matrix-assisted laser desorption ionization time-of-flight mass spectrometry. A total of 68 highly abundant protein spots were successfully identified in the reference 2-DE map based on our T. foetus-specific protein database. The EST dataset and the reference 2-DE map established in the present study will provide a foundation for future whole genome sequencing project and comparative transcriptomic/proteomic analyses to provide potential drug targets against T. foetus infection.

Tritrichomonas foetus is a protist that causes bovine trichomoniasis and presents a well-developed Golgi. There are very few studies concerning the Golgi in trichomonads. In this work, monoclonal antibodies were raised against Golgi of T. foetus and used as a tool on morphologic and biochemical studies of this organelle. Among the antibodies produced, one was named mAb anti-Golgi 20.3, which recognized specifically the Golgi complex by fluorescence and electron microscopy. By immunoblotting this antibody recognized two proteins with 60 and 66 kDa that were identified as putative beta-tubulin and adenosine triphosphatase, respectively. The mAb 20.3 also recognized the Golgi complex of the Trichomonas vaginalis, a human parasite. In addition, the nucleotide coding sequences of these proteins were identified and included in the T. foetus database, and the 3D structure of the proteins was predicted. In conclusion, this study indicated: (1) adenosine triphosphatase is present in the Golgi, (2) ATPase is conserved between T. foetus and T. vaginalis, (3) there is new information concerning the nucleic acid sequences and protein structures of adenosine triphosphatase and beta-tubulin from T. foetus and (4) the mAb anti-Golgi 20.3 is a good Golgi marker and can be used in future studies.

Recently, Tritrichomonas foetus, the known etiologic agent of bovine trichomonosis was identified in domestic cats in many countries around the world. In felids, this parasite would be a significant cause of large-bowel diarrhoea. Therefore the aim of the present study was to determine for the first time the prevalence of T. foetus infection in French catteries. In this epidemiological survey, rectal swabs from 140 cats participating in three international shows were tested for the presence of motile parasites by microscopy after culturing. The prevalence of T. foetus infection was 14.3% among cats (20/140) and 15.9% among catteries (18/117). These values were similar to those previously obtained in other European countries. Except for the age, no significant associations were found between the presence of T. foetus and various risk factors of infection such as the size of the cattery, the type of food, or the vicinity of a dog. Internal transcribed region of the ribosomal DNA unit was sequenced from the 20 T. foetus isolates identified in this study. They exhibited 100% identity and are homologous with other sequences of strains isolated from domestic cats in other countries.

We used a prospective seroepidemiological approach to investigate endemic abortion in a dairy herd in Arequipa, Peru, and its association with Neospora caninum and bovine viral-diarrhoea virus (BVDV) infections. Between January 2002 and March 2004, 1094 pregnancies were confirmed in 538 cows. Of these, 137 pregnancies (13%) in 121 cows ended in abortion. The serological status to N. caninum was assessed using a single serological screening, whereas BVDV status was assessed at the herd level through consecutive samplings of young stock. Cox proportional-hazards models were used to estimate the effect of N. caninum and BVDV on the hazard of early (between day 42 and day 100 in gestation), and late (after day 100) abortions, respectively. Serological status to N. caninum was included as a dichotomous variable, and the effect of BVDV estimated at the herd level, as a time-dependent seasonal effect. Because data from repeated pregnancies were included, we considered possible lack of independence between observations and included frailty effects into the models. Our models also considered the possible confounding by parity and animal origin. Only multiparity was associated with the hazard of early abortion (HR=2.8 compared to nulliparous heifers). N. caninum seropositivity significantly affected the hazard of late abortion, but interacted with parity. The HRs for Neospora-positive animals were 6.4, 3.7 and 1.9, respectively, for nulliparous heifers, first-lactation cows and multiparous cows. Evidence of BVDV circulating (or not) among the young stock was not associated with abortions, but few cows in this herd were susceptible to incident infection.

The parasitic protists in the genus Tritrichomonas cause significant disease in domestic cattle and cats. To assess the genetic diversity of feline and bovine isolates of Tritrichomonas foetus (Riedmüller, 1928) Wenrich and Emmerson, 1933, we used 10 different genetic regions, namely the protein coding genes of cysteine proteases 1, 2 and 4-9 (CP1, 2, 4-9) involved in the pathogenesis of the disease caused by the parasite. The cytosolic malate dehydrogenase 1 (MDH1) and internal transcribed spacer region 2 of the rDNA unit (ITS2) were included as additional markers. The gene sequences were compared with those of Tritrichomonas suis (Davaine, 1875) Morgan and Hawkins, 1948 and Tritrichomonas mobilensisCulberson et al., 1986. The study revealed 100% identity for all 10 genes among all feline isolates (=T. foetus cat genotype), 100% identity among all bovine isolates (=T. foetus cattle genotype) and a genetic distinctness of 1% between the cat and cattle genotypes of T. foetus. The cattle genotype of T. foetus was 100% identical to T. suis at nine loci (CP1, 2, 4-8, ITS2, MDH1). At CP9, three out of four T. suis isolates were identical to the T. foetus cattle genotype, while the T. suis isolate SUI-H3B sequence contained a single unique nucleotide substitution. Tritrichomonas mobilensis was 0.4% and 0.7% distinct from the cat and cattle genotypes of T. foetus, respectively. The genetic differences resulted in amino acid changes in the CP genes, most pronouncedly in CP2, potentially providing a platform for elucidation of genotype-specific host-pathogen interactions of T. foetus. On the basis of this data we judge T. suis and T. foetus to be subjective synonyms. For the first time, on objective nomenclatural grounds, the authority of T. suis is given to Davaine, 1875, rather than the commonly cited Gruby and Delafond, 1843. To maintain prevailing usage of T. foetus, we are suppressing the senior synomym T. suisDavaine, 1875 according to Article 23.9, because it has

Bovine viral diarrhea virus 1 (BVDV-1) subtype b was isolated from premature Holstein calves from a dairy herd that experienced an outbreak of premature births, late-term abortions, brachygnathism, growth retardation, malformations of the brain and cranium, and rare extracranial skeletal malformations in calves born to first-calf heifers. Experimental inoculation of 3 colostrum-deprived calves aged 2-4 months old with this BVDV isolate resulted in thrombocytopenia, lymphopenia, and leukopenia. Outbreaks of brachygnathism are rarely associated with BVDV, and thrombocytopenia is rarely associated with BVDV-1 strains.

Tritrichomonas foetus is a very intriguing trichomonad protozoan with respect to its varied choice of residence in the different host species. It is an obligate parasite of the reproductive and the gastrointestinal tract of bovine and feline host respectively, leading to trichomonosis. Bovine trichomonosis is a sexually transmitted disease whereas feline trichomonosis is a disease with a purported fecal-oral route of spread. Further, the trichomonad is a commensal in the nasal passages, stomach, cecum and colon of swine host. Advances have been exponential in understanding the trichomonad biology and specifically feline trichomonosis since late 1990s and early 2000s when T. foetus was soundly determined to be a causative agent of chronic diarrhea in the domestic cat. It is a challenging task, even for a skilled investigator not to mention the busy clinical veterinarian, to keep up with the vast volume of information. Here we comprehensively reviewed the trichomonad biology, clinical manifestations, pathogenesis, host immunity, world map of distribution, risk factors, diagnosis and treatment. Risk factors associated with T. foetus-positive status in the domestic cat include young age, purebred, history of diarrhea, co-infections with other enteral pathogens. In addition, molecular similarity of bovine and feline isolates of T. foetus in DNA sequence was concisely discussed. The data presented serve as an information source for veterinarians, and investigators who are interested in biology of T. foetus and feline trichomonosis.
The most plausible pro-life argument claims that abortion is seriously wrong because it deprives the foetus of something valuable. This paper examines two recent versions of this argument. Don Marquis's version takes the valuable thing to be a 'future like ours', a future containing valuable experiences and activities. Jim Stone's version takes the valuable thing to be a future containing conscious goods, which it is the foetus's biological nature to make itself have. I give three grounds for rejecting these arguments. First, they lead to unacceptable inequalities in the wrongness of killing. Second, they lead to counterintuitive results in a range of imaginary cases. Third, they ignore the role of psychological connectedness in determining the magnitude or seriousness of deprivation-based harms: because the foetus is only weakly psychologically connected to its own future, it cannot be seriously harmed by being deprived of that future.

Prevalence of Tritrichomonas foetus among Dutch cats The aim of this study was to determine the prevalence of and risk factors for, Tritrichomonas foetus among cats in the Netherlands. A total of 154 faecal samples were collected from three groups of cats: cats with diarrhoea (n=53), cattery cats (n=47), and healthy pet cats (n=54). Faecal samples were examined with a T. foetus specific real-time PCR. All PCR-positive samples were run on gel electrophoresis for definitive diagnosis. The prevalence of T. foetus was 2% among cats with diarrhoea and 4% among cattery cats; T. foetus was not prevalent among pet cats (none of the samples tested positive). Questionnaires had been distributed to cat and cattery owners to determine risk factors for T. foetus, but the low prevalence precluded statistical analysis of the questionnaire results.

Tritrichomonas foetus is a serious veterinary parasite that causes bovine trichomoniasis, a sexually transmitted disease that results in reproductive failure and considerable economic losses in areas that practice natural breeding. T. foetus is an extracellular parasite, which initially adheres to and infects the urogenital tract using a diverse array of surface glycoconjugates, including adhesins and extracellular matrix-binding molecules. However, the cellular mechanisms by which T. foetus colonizes mucosal surfaces and causes tissue damage are not well defined. Several studies have demonstrated the involvement of pathogen or host lipid rafts in cellular events that occur during pathogenesis, including adhesion, invasion and evasion of the immune response. In this study, we demonstrate that detergent-resistant membranes are present in the plasma membrane of T. foetus. We further demonstrate that microdomains are cholesterol-enriched and contain ganglioside GM1-like molecules. In addition, we demonstrate that lipid microdomains do not participate in T. foetus adhesion to host cells. However, the use of agents that disrupt and disorganize the plasma membrane indicated the involvement of the T. foetus lipid microdomains, in cell division and in the formation of endoflagellar forms. Our results suggest that trophozoites and endoflagellar forms present a different plasma membrane organization.

The in vitro hemolytic activity of Tritrichomonas foetus was investigated. The parasite was tested against human erythrocytes of groups A, B, AB, and O, and against erythrocytes of nine adult animals of different species (the rabbit, rat, chicken, cat, dog, swine, horse, bovine, and sheep). The results showed that T. foetus strains (ATCC KV1, K, PAL, 5022, RJ, 90) did not present any hemolytic activity against any human erythrocyte group nor against rabbit, rat, chicken, cat, dog and swine erythrocytes. T. foetus strains, however, lysed horse, bovine, and sheep erythrocytes. No hemolysin released by the parasites could be identified. Hemolysis did not occur with trichomonad culture supernatants, with sonicated extracts of T. foetus, nor with killed organisms. Scanning electron microscopy (SEM) showed that human erythrocytes did not adhere to the trophozoites, in contrast horse erythrocytes adhered to the surface of the parasites and were phagocytosed for up to 90 min. The parasites are able to exert their cytopathic effects through: (a) physical contact established between the two cell surfaces, (b) toxins released from parasites into the interaction media, or (c) the association of both mechanisms. Further studies are necessary to clarify the importance of the hemolytic activity in the biology of T. foetus.

Outbreaks of abortions and lambs born with nervous clinical signs and/or congenital malformations affected different sheep farms in Spain. Initial diagnosis of 'border disease-like' was established, based on clinical signs, serology and/or RNA detection by a pan-pestivirus RT-PCR. However, further investigation using immunohistochemical and molecular techniques identified BVDV-2b as the aetiological agent.

The venereal pathogen Tritrichomonas foetus causes early embryonic death and abortion in cattle. With no approved treatment, control involves detection of infected animals and their removal from the herd. Culture is the traditional diagnostic method; standard media are formulated to support protozoal growth while suppressing competing organisms which may prevent microscopic recognition of T. foetus. Real-time PCR increases diagnostic sensitivity and specificity over culture but requires intact T. foetus DNA for detection. The purposes of this study were 1) to evaluate the effects of resident preputial bacteria that are not suppressed by antimicrobials in a commercial culture medium (InPouch™) on T. foetus detection by culture and PCR, and 2) to determine the performance of a laboratory-prepared culture medium on T. foetus detection by culture and PCR in samples with and without this bacterial contamination. A known concentration of one of three different strains of T. foetus inoculated into InPouch™ (IP) or modified Diamonds-Plastridge media (DPM) were co-incubated with a smegma culture media (CONTAM) for 24h and examined microscopically for the presence of identifiable T. foetus. PCR was performed on IP samples to determine if CONTAM also affected T. foetus DNA detection. A PCR protocol was then validated in DPM that performed similarly to the established IP PCR method. IP and DPM with CONTAM were spiked with serial dilutions that mimic field infections of one of four T. foetus strains and evaluated by real-time PCR; cycles to threshold (Ct) values and "positive" classification were compared between media. T. foetus motility and morphology as well as media pH were severely altered in IP samples with CONTAM compared to those without as well as to DPM medium with and without CONTAM (P<0.0001). PCR testing demonstrated significantly greater Ct values were for T. foetus DNA (P<0.001) in IP contaminated with smegma bacteria compared to those without. When using T

A total of 173 aborted ovine foetuses and seven aborted caprine foetuses, submitted from different points of north and central Spain, were analysed to determine the role of T. gondii in abortion and to compare the utility of the most widely used techniques in diagnosis of the congenital infection (histopathology, serology--IFAT and ELISA--and a nested-PCR). Parasite infection was diagnosed in 40 (23.1%; n = 173) ovine foetuses by at least one of the diagnostic techniques used. A higher percentage of foetuses were diagnosed using serological techniques (IFAT and ELISA) (28.3%; n = 106) than by histologic examination (8.7%; n = 173) or PCR (6.9%; n = 173). No significant association between infection and the foetal age categories was found (P > 0.05). In this study, 106 aborted foetuses were analysed by all of the three diagnostic techniques. When we compared serological results, perfect agreement between ELISA and IFAT was obtained. On the contrary, slight to fair agreements were observed when histology results were compared with those obtained by serology and PCR techniques. All the positive foetuses were aborted in the mid (60%) or last (40%) term of pregnancy, but no significant differences were found between ages of the infected and non-infected foetuses (P > 0.05). This report indicates that toxoplasmosis may be a common cause of small ruminant abortion and neonatal death in Spain and points out the necessity of using different and complementary techniques to increase the probability of detecting Toxoplasma infection in an aborted foetus.

Tritrichomonas foetus (T. foetus) is the causal agent of bovine tritrichomonosis (BT), a venereal disease that causes significant economic losses in the bovine livestock industry. The structural organization of T. foetus presents a cell membrane, an undulating membrane which extends along the parasite, three anterior flagella and a recurrent posterior flagellum. The interaction between the superficial glycoconjugates of the parasite and the host cell is one of the most relevant pathogenic mechanisms. In the present study, we analyzed the saccharide pattern through lectincytochemistry of the cell membrane, undulating membrane, cytoplasm and flagella of 28 isolates of T. foetus. Lectins that labeled most of the isolates were WGA, Con-A, RCA-I, LCA, GS-II and PHA-E showing the presence of D-mannose, D-glucose, N-acetylglucosamine and sialic acid. On the other hand, no labeling was observed in any of the structures with VVA, STA, LEA, Jacalin, GS-I, SJA, PHA-L, DSA, and weak labeling was observed with DBA, PNA, SBA and UEA I, showing therefore a low expression of N-acetylgalactosamine, L-fucose and galactose. In addition, GS II labeled in a granular pattern when lectincytochemistry was positive, whereas LCA strongly labeled the membranes and weakly the cytoplasms. The labeling variations observed among the isolates analyzed in the present work, could be related to differences in the pathogenic behavior of the isolates.

Traumas of the foetus caused by stabbings are rare but actually life-threatening for both the foetus and the mother. We report a case of penetrating chest wound on a baby taken from the obstetrics unit to the paediatric surgical department. His mother was assaulted by his father, a mentally sick person with no appropriate follow-up. The foetus did not show any sign of vital distress. Surgical exploration of the wound has revealed a section of the 10 th rib, a laceration of the pleura and a tearing of the diaphragm. A phrenorraphy and a pleural drainage were performed. The new-born and its mother were released from hospital after 5 days and the clinical control and X-ray checks 6 months later showed nothing abnormal. We insisted a medical, psychiatric follow-up be initiated for the father. As regards pregnant women with penetrating wounds, the mortality rate of the foetus is 80%. The odds are good for our newborn due to the mild injuries and good professional collaboration of the medical staff. Penetrating transuterine wounds of the foetus can be very serious. The health care needed should include many fields due to the mother and the foetus' lesions extreme polymorphism. In our case, it could have prevented by a good psychiatric followed up of the offender.

Tritrichomonas foetus is a pathogenic protozoan that causes a venereal disease in cattle known as bovine genital tricomonosis. In spite of the efficacy to recognize the target genomic DNA, the protocols so far developed for the diagnosis of this organism by PCR promote some inespecific amplifications or they are unable to discriminate T. foetus against other species within the genus. The objective of this study was to assess and optimize PCR and nested-PCR assays for the specific diagnosis of T. foetus, using novel primers selected from the alignment of sequences of the genes 18S rRNA, 5.8S rRNA, 28S rRNA and of the internal transcribed spacers of the rDNA (ITS1 and ITS2). A pair of primers was constructed for the genus-specific amplification of a 648 bp fragment and two others to amplify T. foetus species-specific fragments of 343 and 429 bp. No cross amplification was observed against Bos taurus genomic DNA neither against the DNA of usual bovine genital pathogens. Both, single and nested-PCR assays, presented analytical sensitivity to detect at least two T. foetus organisms.

Feline intestinal trichomoniasis caused by Tritrichomonas foetus is associated with large bowel diarrhea in cats from many parts of the world. It has long been recognized as an economically important sexually transmitted disease that causes early abortion in cattle. Isolates of T. foetus from cattle are infectious for the large intestine of cats and isolates of T. foetus from cats are infectious for the reproductive system of cattle. The parasite is maintained by fecal-oral transmission in cats. The present study was conducted to examine the survival of a feline isolate of T. foetus, AUTf-12, under various conditions that are relevant to fecal-oral transmission in cats. Trophozoites were grown in TYM medium and then exposed to water, cat urine, dry cat food, canned cat food, clumping cat litter, or filter paper for various lengths of time and then re-cultured in TYM medium. Trophozoites survived exposure to distilled or tap water for 30 but not 60 min, while they survived for at least 180 min in urine. Trophozoites survived for 30 min on dry cat food but survived for 120-180 min in canned cat food. No survival of trophozoites was observed on cat litter but trophozoites survived for 15 min when placed on filter paper. Our results indicate that T. foetus can survive and be potentially infectious in water, urine, dry cat food and canned cat food.

Successful mammalian reproduction requires that sperm migrate through a long and convoluted female reproductive tract before reaching oocytes. For many years, fertility studies have focused on biochemical and physiological requirements of sperm. Here we show that the biophysical environment of the female reproductive tract critically guides sperm migration, while at the same time preventing the invasion of sexually transmitted pathogens. Using a microfluidic model, we demonstrate that a gentle fluid flow and microgrooves, typically found in the female reproductive tract, synergistically facilitate bull sperm migration toward the site of fertilization. In contrast, a flagellated sexually transmitted bovine pathogen, Tritrichomonas foetus, is swept downstream under the same conditions. We attribute the differential ability of sperm and T. foetus to swim against flow to the distinct motility types of sperm and T. foetus; specifically, sperm swim using a posterior flagellum and are near-surface swimmers, whereas T. foetus swims primarily via three anterior flagella and demonstrates much lower attraction to surfaces. This work highlights the importance of biophysical cues within the female reproductive tract in the reproductive process and provides insight into coevolution of males and females to promote fertilization while suppressing infection. Furthermore, the results provide previously unidentified directions for the development of in vitro fertilization devices and contraceptives.

Photodynamic therapy (PDT) is a modality of therapy that involves the activation of photosensitive substances and the generation of cytotoxic oxygen species and free radicals to promote the selective destruction of target tissues. This study analyzed the application of PDT to Tritrichomonas foetus, a scourged and etiological agent of bovine trichomoniasis, a sexually transmitted infectious disease. As it is an amitochondrial and aerotolerant protozoan, it produces energy under low O2 tension via hydrogenosome. T. foetus from an axenic culture was incubated with photosensitizer tetrasulfonated aluminium phthalocyanine and then irradiated with a laser source (InGaAIP) at a density of 4.5Jcm(-2). The DNA integrity of the control and treated group parasites was analyzed by conventional gel electrophoresis and comet assay techniques. In previous results, morphological changes characterized by apoptotic cell death were observed after T. foetus was submitted to PDT treatment. In the treated groups, T. foetus DNA showed a higher concentration of small fragments, about 200pb, in gel electrophoresis after PDT. In the comet assay, the DNA tail percentage was significantly higher in the treated groups. These results demonstrate that PDT leads to DNA fragmentation with changes in nuclear morphology and apoptotic features.

Treatment of cultures of Tritrichomonas foetus with 4 mM hydroxyurea (HU), a known DNA synthesis inhibitor, induced pseudocyst formation and caused a mitotic burst. An hour after drug release there was a characteristic, synchronous burst of cell division. T. foetus culture was arrested in the G2/M phase. The synchrony index varied from 66% to 69%. The synchrony was maintained for several cell cycles, even in thawed cultures which had been frozen for storage in liquid nitrogen. The synchronized cells were analyzed by light and scanning electron microscopy, as well by flow cytometry.
Abortion is common. Data on abortion rates are inexact but can be used to explore trends. Globally, the estimated rate in the period 2010-2014 was 35 abortions per 1000 women (aged 15-44 years), five points less than the rate of 40 for the period 1990-1994. Abortion laws vary around the world but are generally more restrictive in developing countries. Restrictive laws do not necessarily deter women from seeking abortion but often lead to unsafe practice with significant mortality and morbidity. While a legal framework for abortion is a prerequisite for availability, many laws, which are not evidence based, restrict availability and delay access. Abortion should be available in the interests of public health and any legal framework should be as permissive as possible in order to promote access. In the absence of legal access, harm reduction strategies are needed to reduce abortion-related mortality and morbidity. Abortion can be performed surgically (in the first trimester, by manual or electric vacuum aspiration) or with medication: both are safe and effective. Cervical priming facilitates surgery and reduces the risk of incomplete abortion. Diagnosis of incomplete abortion should be made on clinical grounds, not by ultrasound. Septic abortion is a common cause of maternal death almost always following unsafe abortion and thus largely preventable. While routine follow-up after abortion is unnecessary, all women should be offered a contraceptive method immediately after the abortion. This, together with improved education and other interventions, may succeed in reducing unintended pregnancy.
A summary of an article which describes how persons form attitudes toward abortion is presented. 3 parameters play roles in the formation of attitudes toward abortion. One such parameter is the decision for which cases abortion is to be allowed. A second parameter is the person's conception of when life commences. A third parameter is formed by unconscious or non-reasoned attitudes which relate to abortion. A model depicts the interaction of these parameters to form opinions about abortion ranging from "abortion is murder" to "liberalize abortion." This leads to the consideration of more general ethical problems. Arguments for and against abortion are listed, as well as improtant statistics concerning abortion from 1975.

Tritrichomonas foetus, a parasite of cattle reproductive system, has been recently discovered as a cause of disease in cats in many countries. T. foetus infects and colonizes cat's ileum, caecum, colon and can lead to enteritis. This paper presents the first clinical case of cat intestinal trichomonosis caused by T. foetus in Poland. The material for this study was a smear collected from a 6-month-old male British Shorthair cat. The presence of parasitic protozoan was determined via microscopic examination and confirmed by amplification of T. foetus rDNA using polymerase chain reaction (PCR) technique. In the first PCR reaction, a DNA of Trichomonadidae was identified and in the second PCR, T. foetus was detected. The T. foetus positive products from the second PCR reaction were sequenced. Interpretation of the sequencing results of obtained amplicons by comparing them with the GenBank database proved that the causative agent, in this case, was T. foetus.

National abortion laws usually do not allow abortion when a foetus is independently viable, i.e. from a gestational age of about 24 weeks. Fetal anomalies, which may be a reason to seek abortion, are sometimes detected only in an advanced stage of pregnancy. National legislatures who want to allow 'late' abortion need to account for the protection the fetus may derive from the European Convention for the protection of human rights. As yet it remains unclear to what extent the fetus can in fact derive protection from the Convention, although several national abortion laws have been tested against it by the European Commission. The significance of the reports of the Commission on the question whether national legislation allowing abortion of a viable fetus is in conflict with the Convention, is explored. It is concluded that there is no European legal standard in terms of duration of pregnancy to which national legislatures are committed.

Sexual assault or rape cases occasionally result in unwanted pregnancies. In almost all such cases the foetus is aborted. A forensic laboratory may receive the foetus, the placenta, or paraffin embedded abortion material for paternity testing. Obtaining a foetal profile DNA from a foetus or placenta may not be successful due to the age or condition of the tissue. Moreover, maternal contamination of placental material will invariably result in a mixed DNA profile. However, the use of properly screened abortion material from paraffin blocks will almost always result in obtaining a foetal DNA profile. Furthermore, foetal tissue fixed in paraffin blocks does not require special conditions for submission and storage as required to preserve fresh foetal or placental tissue. As hospitals routinely prepare foetal tissue in paraffin blocks, which should be readily obtainable by forensic laboratories, these samples would appear to be the preferred choice for paternity testing.

Tritrichomonas foetus causes a venereal infection in cattle; the disease has mild or no clinical manifestation in bulls, while cows may present vaginitis, placentitis, pyometra and abortion in the more severe cases. T. foetus has one of the largest known genomes among trichomonads. However molecular data are fragmentary and have minimally contributed to the understanding of the biology and pathogenesis of this protozoan. In a search of new T. foetus genes, a detailed exploration was performed using recently available expressed sequences. Genes involved in the central carbon metabolism (phosphoenol pyruvate carboxykinase, glyceraldehyde-3-phosphate dehydrogenase, fructose-1,6-bisphosphate aldolase, thioredoxin peroxidase, alpha and beta chains of succinyl CoA synthetase, malate dehydrogenase, malate oxidoreductase and enolase) as well as in cell structure and motility (actin, α-tubulin and β-tubulin) were found duplicated and, in many cases, repeatedly duplicated. Homology analysis suggested that massive expansions might have occurred in the T. foetus genome in a similar way it was also predicted for Trichomonas vaginalis, while conservation assessment showed that duplications have been acquired after differentiation of the two species. Therefore, gene duplications might be common among these parasitic protozoans.

1. Isoprenaline injection into either the unanaesthetized ovine foetus or the pregnant ewe produced a transient tachycardia and hypotension in either the ewe or the foetus. No evidence was obtained for placental transfer, in either direction, of pharmacologically active isoprenaline.2. Propranolol, when given to the ewe intravenously, produced bradycardia and increased pulse pressure and inhibited the response of both the ewe and her foetus to isoprenaline. Propranolol, when given to the foetus intravenously, produced bradycardia and increased pulse pressure in both the foetus and the ewe, but only the foetal response to isoprenaline was inhibited. These data demonstrated that propranolol crossed the ovine placenta in both directions in a pharmacologically active form.3. Dose-heart rate curves of the foetus and pregnant ewe to isoprenaline and the shift to the right of the isoprenaline dose-response curves by propranolol were similar in both the ewe and the foetus.4. Notwithstanding the similarities between the ewe and foetus in their responses to isoprenaline or propranolol and in the antagonism of isoprenaline by propranolol, the duration of blockade following propranolol administration to the ewe was 2 to 3 times longer in the foetus compared with the ewe.5. Measurement of blood levels of propranolol showed that the maximum concentration of propranolol in foetal plasma was only 5% of that in the pregnant ewe when propranolol was infused into the ewe; the rate of clearance of propranolol was similar from the foetal and maternal plasma.6. From these data the long duration of beta-adrenoceptor blockade in the ovine foetus by propranolol cannot be fully explained. However, these data serve as examples of the dangers involved when extrapolating pharmacological actions of drugs on the foetus purely from data on foetal plasma levels of the drug.7. The data suggest that multiple doses of propranolol, given to maintain a beta-adrenoceptor blockade in the mother, could

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

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.

Abortion-related deaths, which account for 47% of total maternal mortality in the world, result primarily from sepsis and are widespread in developing countries where abortion is illegal or inaccessible. Septic abortion offers opportunities for prevention on the primary, secondary, and tertiary level of medial care. Primary prevention of septic abortion encompasses the provision of effective contraception, provision of safe and legal abortion in cases of contraceptive failure, and appropriate medical management of abortion. Secondary prevention involves the prompt diagnosis of endometriosis and effective treatment to avert more serious infection. The diagnosis of septic abortion should be considered when women of reproductive age present to health facilities with vaginal bleeding, lower abdominal pain, and fever. Tertiary prevention is aimed at avoiding the serious complications of postabortal infection, including hysterectomy and death. Women with high fever, pelvic peritonitis, and tachycardia should undergo uterine evacuation and parental antibiotic therapy. Supportive care for cardiovascular system and other organs may be essential. The medical technology needed to avert serious complications and deaths from septic abortion is available. Lacking is a political commitment on the part of many governments and health care agencies to address this avoidable contributor to maternal morbidity and mortality.

Vaccines against both bovine venereal campylobacteriosis and trichomonosis were tested. Heifers were assigned to three groups. Groups 1 (n = 21 heifers) and group 2 (n = 20) received a commercial or experimental vaccine, respectively, containing both Campylobacter fetus and Tritrichomonas foetus antigens. Group 3 (n = 21) received adjuvant alone. Preparations were injected SQ in groups 1 and 3 at days -60 and -30 (day 0 was considered the first day of a 90-day breeding period), and in group 2 SQ at days -30 and +11 and into the vaginal submucosa at day -9. Heifers were exposed to two pathogen-infected bulls for 90 days (from day 0 to day +90); furthermore, half of the heifers in each group were challenged at day +39 by an intravaginal instillation of C. fetus venerealis and T. foetus. Pregnancy diagnosis, vaginal culture, and determination of systemic IgG for both organisms were performed. Compared to controls, vaccinated heifers resisted or quickly cleared both pathogens, had a higher pregnancy rate and a higher systemic immune response during and after the breeding period. Overall, the experimental vaccine was superior to the commercial vaccine (groups 2 and 1, respectively). In conclusion, an experimental vaccine containing both C. fetus and T. foetus antigens, given both SQ and intravaginal immediately before breeding and early in the breeding season, yielded superior protection for heifers exposed to bulls harboring C. fetus and T. foetus.

Tritrichomonas foetus is a flagellated protozoan parasite that causes trichomoniasis, a major sexually transmitted disease in cattle. T. foetus presents a simple life cycle, exhibiting only the trophozoitic form. However, under unfavorable growth conditions, the trophozoites, which are polar and flagellated, can round up and internalize their flagella forming pseudocysts. In this form no cyst wall surrounds the cell and it also displays a distinct mitosis when compared with the trophozoite form. In pseudocyst mitosis, the cell proceeds with duplication of cytoskeletal and mastigont structures; nuclear division occurs but without the corresponding cytoplasm division. Thus, giant multinucleated cells which present many mastigont structures are formed (approximately 62% of the population). These polymastigont/multinucleated cells are maintained when the cells are under stress conditions. When environmental conditions become favorable, the flagella are externalized and new flagellated trophozoites one by one, gradually bud from the multinucleated cell. Thus, in order to better understand the pseudocyst mitosis, the polymastigont formation and the generation of new cells by this budding process, video microscopy and other complementary techniques, such as immunofluorescence and transmission electron microscopy were used.
The somatic and flagellar serum agglutinin titre were determined in paired samples obtained from seventy-seven cases of bovine abortion associated with Salmonella dublin infection. The cases could be divided into four serological groups with an active infection being demonstrated in most cases. The serum agglutination test was shown to be a relatively specific diagnostic test but was of more limited value in the retrospective identification of convalescent cases. PMID:4518345

Nurses have opinions about abortion, but because they are health professionals and their opinions are sought as such, they are obligated to understand why they hold certain views. Nurses need to be clear about why they believe as they do, and they must arrive at a point of view in a rational and logical manner. To assist nurses in this task, the ethical issues surrounding abortion are enumerated and clarified. To do this, some of the philosophic and historic approaches to abortion and how a position can be logically argued are examined. At the outset some emotion-laden terms are defined. Abortion is defined as the expulsion of a fetus from the uterus before 28 weeks' gestation, the arbitrarily established time of viability. This discussion is concerned only with induced abortion. Since the beginning of recorded history women have chosen to have abortions. Early Jews and Christians forbade abortion on practical and religious grounds. A human life was viewed as valuable, and there was also the practical consideration of the addition of another person to the population, i.e., more brute strength to do the necessary physical work, defend against enemies, and ensure the continuation of the people. These kinds of pragmatic reasons favoring or opposing abortion have little to do with the Western concept of abortion in genaeral and what is going on in the U.S. today in particular. Discussion of the ethics of abortion must rest on 1 or more of several foundations: whether or not the fetus is a human being; the rights of the pregnant woman as opposed to those of the fetus, and circumstances of horror and hardship that might surround a pregnancy. Viability is relative. Because viability is not a specific descriptive entity, value judgments become part of the determination, both of viability and the actions that might be taken based on that determination. The fetus does not become a full human being at viability. That occurs only at conception or birth, depending on one's view
After oral administration of ewes during mid gestation with 2000 freshly prepared sporulated oocysts of T. gondii isolate M4, abortions occurred between days 7 and 11 in 91.6% of pregnant and infected ewes. Afterwards, a further infection was carried out at late gestation in another group of sheep with 500 sporulated oocysts. Abortions happened again between days 9 and 11 post infection (pi) in 58.3% of the infected ewes. Classically, abortions in natural and experimental ovine toxoplasmosis usually occur one month after infection. Few experimental studies have reported the so-called acute phase abortions as early as 7 to 14 days after oral inoculation of oocysts, and pyrexia was proposed to be responsible for abortion, although the underline mechanism was not elucidated. In the present study, all placentas analysed from ewes suffering acute phase abortions showed infarcts and thrombosis in the caruncullar villi of the placentomes and ischemic lesions (periventricular leukomalacia) in the brain of some foetuses. The parasite was identified by PCR in samples from some placentomes of only one sheep, and no antigen was detected by immunohistochemical labelling. These findings suggest that the vascular lesions found in the placenta, and the consequent hypoxic damage to the foetus, could be associated to the occurrence of acute phase abortions. Although the pathogenesis of these lesions remains to be determined, the infectious dose or virulence of the isolate may play a role in their development. PMID:24475786

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. PMID:25904951

The objective is to discuss sexually transmitted diseases caused by Tritrichomonas foetus (T foetus) and Campylobacter fetus (C fetus) subsp. venerealis, with a focus on prevalence, pathogenesis, and diagnosis in cows and bulls. Diagnosis and control are problematic because these diseases cause severe reproductive losses in cows, but in bulls are clinically asymptomatic, which allows the disease to flourish, especially in the absence of legislated control programs. We review research regarding prophylactic systemic immunization of bulls and cows with antigens of T foetus and C fetus venerealis and their efficacy in preventing or clearing preexisting infections in the genital tract. Current diagnostic methods of C fetus venerealis and T foetus (microbial culture and PCR) should be improved. Review of the latest advances in bovine trichomoniasis and campylobacteriosis should promote knowledge and provide an impetus to pursue further efforts to control bovine sexually transmitted diseases.
Background Bovine brucellosis is an important disease affecting cattle characterised by abortion, still birth, reduced milk production, weak foetus and infertility in both males and females. There is wide distribution of the disease among cattle and several wildlife species. Bovine brucellosis is commonly caused by B. abortus and very occasionally B. melitensis and B. suis. The distribution of bovine brucellosis in cattle has not been described in Malaysia. In this paper we describe the distribution, pattern and trend of bovine brucellosis in Peninsular Malaysia between 2000 and 2008 based on serological data obtained from nationwide B. abortus serosurveillance activities in cattle populations. Results Brucella antibodies were detected in 21.8% of sampled herds (95% CI, 21.01–22.59) and 2.5% (95% CI; 2.45–2.55) of sampled cattle. The state of Pahang had the highest animal and herd-level seroprevalence of 5.3 and 43.6%, respectively. The herd-level seroprevalence varied but remained high (18-26%) over the period of study and generally increased from 2000 to 2008. Seropositive herds clustered around the central part of the peninsula within the period of the study. The months of September, October and November illustrated the highest rates with corresponding seroprevalences of 33.2, 38.4 and 33.9%, respectively. A noticeable variation was observed in the cattle-level seroprevalence, but the rate remained relatively low (<5%). The chi-square statistics showed herd size (χ2 = 1206.077, df = 2, p = 0.001), breed (χ2 = 37.429, df = 1, p = 0.001), month of sampling (χ2 = 51.596, df = 11 p = 0.001), year (χ2 = 40.08, df = 8, p = 0.001) and state (χ2 = 541.038, df = 10, p = 0.001) to be associated with increased seropositivity. Conclusion Bovine brucellosis is widespread among herds in Peninsular Malaysia at a low within-herd seroprevalence rate. PMID:24246015
Philosophical debate about the ethics of abortion has reached stalemate on two key issues. First, the claim that foetuses have moral standing that entitles them to protections for their lives has been neither convincingly established nor refuted. Second, the question of a pregnant woman's obligation to allow the gestating foetus the use of her body has not been resolved. Both issues are deadlocked because philosophers addressing them invariably rely on intuitions and analogies, and such arguments have weaknesses that make them unfit for resolving the abortion issue. Analogical arguments work by building a kind of consensus, and such a consensus is virtually unimaginable because (1) intuitions are revisable, and in the abortion debate there is great motive to revise them, (2) one's position on abortion influences judgments about other issues, making it difficult to leverage intuitions about other ethical questions into changing peoples' minds about abortion, and (3) the extent of shared values in the abortion debate is overstated. Arguments by analogy rely on an assumption of the commensurability of moral worldviews. But the abortion debate is currently unfolding in a context of genuinely incommensurable moral worldviews. The article ends by arguing that the default position must be to permit abortion as a consequence of the freedom of conscience protected in liberal societies.

Bovine viral diarrhoea virus (BVDV) is an economically important pathogen of cattle worldwide. Infection of a pregnant animal may lead to persistent infection of the foetus and birth of a persistently infected (PI) calf that sheds the virus throughout its life. However, BVD viruses are not strictly species specific. BVDV has been isolated from many domesticated and wild ruminants. This is of practical importance as virus reservoirs in non-bovine hosts may hamper BVDV control in cattle. A goat given as a social companion to a BVDV PI calf gave birth to a PI goat kid. In order to test if goat to goat infections were possible, seronegative pregnant goats were exposed to the PI goat. In parallel, seronegative pregnant goats were kept together with the PI calf. Only the goat to goat transmission resulted in the birth of a next generation of BVDV PI kids whereas all goats kept together with the PI calf aborted. To our knowledge, this is the first report which shows that a PI goat cannot only transmit BVD virus to other goats but that such transmission may indeed lead to the birth of a second generation of PI goats. Genetic analyses indicated that establishment in the new host species may be associated with step-wise adaptations in the viral genome. Thus, goats have the potential to be a reservoir for BVDV. However, the PI goats showed growth retardation and anaemia and their survival under natural conditions remains questionable.

The biology and control of Giardia spp in dogs and cats, and Tritrichomonas foetus in cats is reviewed, including nomenclature, morphology, life cycle, epidemiology, pathogenic process, clinical signs, diagnosis, treatment and control, and public health aspects. These surprisingly similar protozoan pathogens are both clinically significant in veterinary clinical medicine.

Iron uptake from a low-molecular-weight chelate Fe(III)-nitriloacetate (Fe-NTA) by anaerobic protozoan parasite Tritrichomonas foetus was investigated and compared with that from iron-saturated lactoferrin and transferrin. The results showed that the iron uptake from Fe-NTA was saturable (Km = 2.7 microM, Vmax = 21.7 fmol. microg-1.min-1) and time, and temperature dependent, thus suggesting involvement of a membrane transport carrier. The accumulation of iron from 59Fe-NTA was inhibited by NaF and iron chelators. Amilorid and inhibitors of endosome acidification did not influence the process. Ascorbate stimulated the uptake while a membrane impermeable chelator of bivalent iron (bathophenanthroline disulfonic acid) was inhibitory, suggesting that prior to transport iron is reduced extracellularly. In accord with this assumption, the reduction of ferric to ferrous iron in the presence of intact T. foetus cells was demonstrated. Dynamics and properties of uptake of iron released from transferrin were similar to those from Fe-NTA, indicating involvement of common mechanisms. Iron uptake from lactoferrin displayed profoundly different characteristics consistent with receptor-mediated endocytosis. Metronidazole-resistant derivative of the investigated T. foetus strain showed marked deficiency in iron acquisition from Fe-NTA and transferrin while its iron uptake from lactoferrin was higher than that of the parent strain. The results presented show that T. foetus possesses at least two independent mechanisms that mediate acquisition of iron.

Background: The specific recognition of oesophageal atresia (OA) with or without a tracheal fistula in a foetus is a diagnostic challenge for prenatal medicine. The aim of the present work is to analyse the value of the measurement of gastric size in the diagnosis of this significant malformation. Materials and Methods: Altogether, the examinations of 433 pregnancies between the 18.4 and 39.1 weeks of gestation were retrospectively analysed. 59 of these foetuses exhibited an OA. By means of a linear regression analysis with normal foetuses, significant parameters influencing gastric size were examined. Subsequently the gastric sizes were transformed into z values and a comparison was made between OA with and without fistulae with the help of t tests. Results: In the normal foetuses there was a significant association between the gastric circumference and the abdominal circumference (circumference = 6.809 + 0.179 × abdominal circumference, r = 0.686, p < 0.0001). In the normal group the average was 43.0 (standard deviation [SD] 13.7) mm and those in foetuses with and without fistuale were 33.8 (SD 22.7) and 0.9 (SD 3.7) mm. In 34 (57.6 %) foetuses with an OA, the gastric circumference was below the 5th percentile. In detail, there were 13 (34.2 %) foetuses with a fistula and 21 (100 %) without a fistula. The average z values in the normal group and in the groups of OA with fistula and without fistula amounted to 0.0 (SD 1.0), −1.3 (SD 2.2) and −4.5 (SD 1.0). Conclusion: Measurements of the gastric circumference below the 5th percentile should lead to further diagnostic measures, especially when associated with polyhydramnios. Although OA without a fistula is always conspicuous, only about one in three OAs with fistula are associated with a significantly smaller stomach. PMID:26719598

This brief summary presents information on the epidemiology of abortion requested by IPPF. In 1975, 8% of the world's population lived in areas where the law prohibits abortion completely, and 27% lived in areas where abortions are severely restricted. Over 2 years, 40,000 hospitalizations for abortion complications were reported in such countries, with 168 deaths. 21% of women hospitalized for a diagnosis related to abortion died. In Latin America, hospitalization and death because of illegal abortion led to epidemiological studies. In Chile, surveys indicate that 1/4 women has had an abortion. Colombia data state that 10 women die/week from abortion complications. Bangladesh identified 31 abortion deaths. When related to live births occurring in the area from which the deaths were reported, the abortion mortality ratio was 19/1000,000 live births. Data from Romania showed that before 1966, when abortion was legal, there were fewer than 100 reported deaths. After 1966, when abortion was restricted, crude birth rate increased from 15-40/1000 total population. During the following 4 years, the birth rate dropped until it was below 25, but concomitant deaths due to abortion increased. In 1965, 64 abortion-related deaths occurred, whereas by 1971, abortion-related deaths increased to 364. In North America abortion deaths and number of illegal abortions decreased dramatically after 1973, when abortion became legal in the U.S. In 1972, illegal abortions led to the deaths of 41 women, but in 1974 only 5 such deaths occurred. If women with unplanned or unwanted pregnancies all underwent abortion within the 1st 8 weeks of pregnancy, 90% of the deaths due to legal abortion could be prevented.
Though pregnancy termination is highly restricted in Kenya, induced abortion remains common. Illegal abortion is often unsafe, putting women at risk of death or severe complications. In eastern Africa as a whole, an estimated 14% of all pregnancies end in abortion, and nearly one in five maternal deaths are due to unsafe abortion.

Religion plays a significant role in a patient’s bioethical decision to have an abortion as well as in a country’s abortion policy. Nevertheless, a holistic understanding of the Islamic position remains under-researched. This study first conducted a detailed and systematic analysis of Islam’s position towards abortion through examining the most authoritative biblical texts (i.e. the Quran and Sunnah) as well as other informative factors (i.e. contemporary fatwas, Islamic mysticism and broader Islamic principles, interest groups, and transnational Islamic organizations). Although Islamic jurisprudence does not encourage abortion, there is no direct biblical prohibition. Positions on abortion are notably variable, and many religious scholars permit abortion in particular circumstances during specific stages of gestational development. It is generally agreed that the least blameworthy abortion is when the life of the pregnant woman is threatened and when 120 days have not lapsed; however, there is remarkable heterogeneity in regards to other circumstances (e.g. preserving physical or mental health, foetal impairment, rape, or social or economic reasons), and later gestational development of the foetus. This study secondly conducted a cross-country examination of abortion rights in Muslim-majority countries. A predominantly conservative approach was found whereby 18 of 47 countries do not allow abortion under any circumstances besides saving the life of the pregnant woman. Nevertheless, there was substantial diversity between countries, and 10 countries allowed abortion ‘on request’. Discursive elements that may enable policy development in Muslim-majority countries as well as future research that may enhance the study of abortion rights are discussed. Particularly, more lenient abortion laws may be achieved through disabusing individuals that the most authoritative texts unambiguously oppose abortion, highlighting more lenient interpretations that exist in

Since the dawn of medicine, medical rights and ethics have always been one of mankind's concerns. In any civilisation, attention paid to medical laws and ethics depends on the progress of human values and the advancement of medical science. The history of various civilisations teaches that each had its own views on medical ethics, but most had something in common. Ancient civilisations such as Greece, Rome, or Assyria did not consider the foetus to be alive and therefore to have human rights. In contrast, ancient Persians valued the foetus as a living person equal to others. Accordingly, they brought laws against abortion, even in cases of sexual abuse. Furthermore, abortion was considered to be a murder and punishments were meted out to the mother, father, and the person performing it.

Tritrichomonas foetus has recently been recognised as the cause of large bowel diarrhoea in cats (feline trichomoniasis), for which the epidemiology is largely unknown. We tested whether garden slugs common in Sydney, Australia can pass viable T. foetus in their faeces after oral intake. First, Leopard slugs (Limax maximus) were offered cat food with 10(4) of T. foetus per gram, 63% (5/8) of slugs consumed food with T. foetus and subsequently 20% (1/5) shed T. foetus in their faeces. Furthermore, 63% (5/8) and 75% (6/8) of the Leopard slugs and the Yellow cellar slugs (Limacus flavus) consumed food with 10(6) of T. foetus per gram and subsequently 100% (5/5) and 83% (5/6) shed T. foetus in their faeces, respectively. These results suggest that slugs may facilitate passive transmission of T. foetus between cats. We speculate that cats may become infected with T. foetus should they consume food contaminated with faeces from slug(s) infected with T. foetus.

Iron is an essential element for the survival of trichomonads during host-parasite interaction. The availability of this metal modulates several metabolic pathways of the parasites and regulates the expression of virulence factors such as adhesins and proteolytic enzymes. In this study, we investigated the effect of iron depletion on the morphology and life cycle of Tritrichomonas foetus. Scanning and transmission electron microscopy analyses revealed that depletion of iron from the culture medium (named TYM-DIP inducer medium) induces morphological transformation of typical pear-shaped trophozoites into spherical and non-motile pseudocysts. Remarkably, inoculation of pseudocysts into an iron-rich medium (standard TYM medium), or addition of FeSO4 to a TYM-DIP inducer medium reverted the morphological transformation process and typical trophozoites were recovered. These results show that pseudocysts are viable forms of the parasite and highlight the role of iron as a modulator of the parasite phenotype. Although iron is required for the survival of T. foetus, iron depletion does not cause a cellular collapse of pseudocysts, but instead induces phenotypic alterations, probably in order to allow the parasite to survive conditions of nutritional stress. Together, these findings support previous studies that suggest pseudocysts are a resistance form in the life cycle of T. foetus and enable new approaches to understanding the multifactorial role of iron in the cell biology of this protozoan parasite.

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.
A mouse adaptated strain of Chlamydia ovis, when inoculated in the peritoneal cavity, caused the death of both pregnant and non pregnant mice. In addition, mice inoculated late in pregnancy (12 to 16 days after breeding) aborted 4 to 6 days after inoculation. Chlamydia was recovered from foetuses and from the organs of the mice (Liver, Spleen, Lungs). The severity of the disease was related to the inoculum concentration, so it was possible to induce late abortions with a rapid recovery of the females, like in the natural infection of the ewes. In the same conditions, the original Chlamydia strain maintained by passage on yolk sac, induced only an inapparent disease transmissible to the young mice.

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

Abortion stigma is widely acknowledged in many countries, but poorly theorised. Although media accounts often evoke abortion stigma as a universal social fact, we suggest that the social production of abortion stigma is profoundly local. Abortion stigma is neither natural nor 'essential' and relies upon power disparities and inequalities for its formation. In this paper, we identify social and political processes that favour the emergence, perpetuation and normalisation of abortion stigma. We hypothesise that abortion transgresses three cherished 'feminine' ideals: perpetual fecundity; the inevitability of motherhood; and instinctive nurturing. We offer examples of how abortion stigma is generated through popular and medical discourses, government and political structures, institutions, communities and via personal interactions. Finally, we propose a research agenda to reveal, measure and map the diverse manifestations of abortion stigma and its impact on women's health.
Abortion on medical and eugenic grounds has been legal in most European countries for several years. In Austria, abortions are performed following obligatory counseling, and physicians can abstain conscientiously from performing them. In Denmark, first trimester abortion is performed on request for women over age 17. Abortion has been legal in Finland since 1950; the abortion rate reached its peak in 1973, and has been declining since then. First trimester abortion is legal in France, but a woman seeking admission to a hospital must present a physician's certificate, a counselor's certificate, and her own written consent. Delays in the processing of the application are not unusual and the whole procedure can be lengthy and discouraging. First trimester abortion was legalized in the German Democratic Republic in 1972, and in 1973 in the Federal Republic of Germany, where 79% of abortions are requested on grave social grounds. Applications for abortions are seldom refused in Hungary, where the abortion rate reached 81.1/1000 women in 1971. Abortion on request is expected to be legalized shortly in Norway, while it prevails in Poland, where 98% of abortions are performed for social indications. In Sweden, abortion is performed only in public hospitals, and contraceptive advice and fitting is free. The availability of abortion in the United Kingdom is limited by the restrictive attitude of some National Health Service physicians, and nearly all abortions on nonresidents (32% in 1973) are performed on private premises. In Yugoslavia, abortion is the constitutional right of every woman, but only the Republic of Slovenia has, so far, legislated fertility regulation as a whole, and termination of pregnancy can be performed only with the approval of a special committee.

The legislation and the texts of the most important medical writers of Byzantine times have been studied with reference to abortions, the ethical aspect of this social and medico-legal problem, the theological and the scientific approach. The theoretical basis of the permanent and absolute condemnation of all kinds of abortions except those permitted for medical reasons, is greatly influenced by the spirit of Christianity. In fact, religion supported the view that the reception of the seed in the uterus and the conception of the embryo means the beginning of life and accepted that the foetus is already a living creature. All legislation of Byzantium from the earliest times also condemned abortions. Consequently, foeticide was considered equal to murder and infanticide and the result was severe punishments for all persons who participated in an abortive technique reliant on drugs or other methods. The punishments could extend to exile, confiscation of property and death. The physicians followed the tradition of Ancient Greece, incorporated in the Hippocratic Oath, representative of the ideas of previous philosophers. According to this famous document, it is forbidden them to give a woman "an abortive suppository". The Orthodox faith reinforced this attitute, protective of every human life. On the other hand, the Church and the State accepted selective abortion based on medical data, such as prevention of dangerous conditions in pregnancy or anatomical difficulties involved. In conclusion, science, church and legislation had a common attitude to matters concerning abortion and this fact reveals an effort to apply a fair policy for the rights of the embryo and the protection of human life in Byzantine society.

Each year in Indonesia, millions of women become pregnant unintentionally, and many choose to end their pregnancies, despite the fact that abortion is generally illegal. Like their counterparts in many developing countries where abortion is stigmatized and highly restricted, Indonesian women often seek clandestine procedures performed by untrained providers, and resort to methods that include ingesting unsafe substances and undergoing harmful abortive massage. Though reliable evidence does not exist, researchers estimate that about two million induced abortions occur each year in the country and that deaths from unsafe abortion represent 14-16% of all maternal deaths in Southeast Asia. Preventing unsafe abortion is imperative if Indonesia is to achieve the fifth Millennium Development Goal of improving maternal health and reducing maternal mortality. Current Indonesian abortion law is based on a national health bill passed in 1992. Though the language on abortion was vague, it is generally accepted that the law allows abortion only if the woman provides confirmation from a doctor that her pregnancy is life-threatening, a letter of consent from her husband or a family member, a positive pregnancy test result and a statement guaranteeing that she will practice contraception afterwards. This report presents what is currently known about abortion in Indonesia. The findings are derived primarily from small-scale, urban, clinic-based studies of women's experiences with abortion. Some studies included women in rural areas and those who sought abortions outside of clinics, but none were nationally representative. Although these studies do not give a full picture of who is obtaining abortions in Indonesia or what their experiences are, the evidence suggests that abortion is a common occurrence in the country and that the conditions under which abortion takes place are often unsafe.

Cattery-housed pedigree cats, located mostly within the USA, have the highest reported prevalence of Tritrichomonas foetus (T foetus) to date. This prospective, multi-institutional, cross sectional study examines the occurrence of T foetus and other enteric parasites in cattery-housed and shelter cats within Australia, where T foetus has only recently been identified. Faecal specimens were collected from 134 cats, including 82 cattery-housed pedigree cats and 52 shelter cats. Faecal examinations performed for most cats included concentration techniques, Snap Giardia test, culture in InPouch medium, and polymerase chain reaction (PCR) amplification of T foetus ribosomal ribonucleic acid (rRNA) genes using species-specific primers. Observed occurrence of T foetus, Giardia species, Isospora species and Toxascaris leonina for cattery-housed cats (and catteries) were 0%, 7.4 (13.8)%, 10.9 (22.6)% and 1.6 (3.2)%, respectively. Observed occurrence of T foetus, Giardia species, Isospora species and hookworms for shelter cats were 0%, 11.5%, 9.8% and 4.9%, respectively. These results suggest the prevalence of T foetus in cattery-housed cats is currently much lower in Australia than in the USA, while Isospora and Giardia species infections are common.

To evaluate the efficacy of ronidazole for treatment of Tritrichomonas foetus infection, 6 Tritrichomonas-free kittens were experimentally infected with a Korean isolate of T. foetus. The experimental infection was confirmed by direct microscopy, culture, and single-tube nested PCR, and all cats demonstrated trophozoites of T. foetus by day 20 post-infection in the feces. From day 30 after the experimentally induced infection, 3 cats were treated with ronidazole (50 mg/kg twice a day for 14 days) and 3 other cats received placebo. Feces from each cat were tested for the presence of T. foetus by direct smear and culture of rectal swab samples using modified Diamond's medium once a week for 4 weeks. To confirm the culture results, the presence of T. foetus rRNA gene was determined by single-tube nested PCR assay. All 3 cats in the treatment group receiving ronidazole showed negative results for T. foetus infection during 2 weeks of treatment and 4 weeks follow-up by all detection methods used in this study. In contrast, rectal swab samples from cats in the control group were positive for T. foetus continuously throughout the study. The present study indicates that ronidazole is also effective to treat cats infected experimentally with a Korean isolate of T. foetus at a dose of 50 mg/kg twice a day for 14 days.

Mathematical models of the developing foetus at 8-, 13-, 26- and 38-week gestation were converted into voxels and combined with the reference adult female model, NAOMI at a resolution of 2 mm. Whole-body averaged SAR in the mother is presented as well as the average over the foetus, over the foetal brain and in 10 g of the foetus. The electric field values required to produce the ICNIRP public exposure restriction of 2 W kg(-1) when averaged over 10 g of the foetus were calculated. Comparison suggests that the ICNIRP public reference level is a conservative predictor of local SAR in the foetus.
This piece describes abortion practices in use from the 1600s to the 19th century among the inhabitants of North America. The abortive techniques of women from different ethnic and racial groups as found in historical literature are revealed. Thus, the point is made that abortion is not simply a "now issue" that effects select women. Instead, it is demonstrated that it is a widespread practice as solidly rooted in our past as it is in the present.

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 identified. 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.

This article is about selective abortion. It concentrates on the existential, moral and social conditions that arise when pregnant women, using prenatal diagnosis (PND), are told that there is something seriously wrong with the foetuses that they are carrying. This is characterised as a micro state of emergency, where both normal cognitive categories and normative orders are dissolved. The analyses are anchored in the womens' own presentations and understandings of the processes and dilemmas related to the abortion decisions, and our most important empirical materials are interviews with women who have experienced them. Our main ambition is to show the relation between some important dimensions of the situation in which the abortion decision has to be made, and the special kind of authority on behalf of the women that presents itself. Of equal importance is the vulnerability of the pregnant women, resulting in a co-production of the women as both Sovereigns and Homo Sacer in the decision situation. We also analyse some of the experienced relations between the women and the foetuses, and how the women constitute themselves as moral subjects, with a particular emphasis on the motifs of sacrifice and self-sacrifice. It is a central argument in the article that we have to understand the specificity of the decision situation, without reducing it either to other phases (before or after) of the total processes of PND and selective abortion, or to general discourses of disability or normality. The specificity of the situation in which the abortion decision is made is a pivotal point in society's regulation (in a broad sense) of the field and in the constitution of the regime of selective abortion.

The aim of study was to examine the importance of foetus body mass prepartal assessment in normal term pregnancy. The study comprised 254 pregnant women with single pregnancy, without congenital anomalies, residing in urban (Zagreb) and small towns (Samobor, Jastrebarsko). Higher birth mass was measured in male than in female newborns, and the difference was statistically significant (p < 0.05%, p = 0.002). Older pregnant women more often gave birth by Cesarean section then vaginally and, the difference was statistically significant (p < 0.005; p = 0.009). Smoking and parity did not influence birth mass. The results of the study showed good prepartal estimate of fetal mass in 207 (81.5%) and bad in 47 (18.5%) pregnant women. This study has confirmed the clinical value of ultrasound in prepartal treatment of pregnancy. Since the child gender was shown to have an impact on the assessment, it is well advised to determine the child gender as well.

Cortical learning via sensorimotor experiences evoked by bodily movements begins as early as the foetal period. However, the learning mechanisms by which sensorimotor experiences guide cortical learning remain unknown owing to technical and ethical difficulties. To bridge this gap, we present an embodied brain model of a human foetus as a coupled brain-body-environment system by integrating anatomical/physiological data. Using this model, we show how intrauterine sensorimotor experiences related to bodily movements induce specific statistical regularities in somatosensory feedback that facilitate cortical learning of body representations and subsequent visual-somatosensory integration. We also show how extrauterine sensorimotor experiences affect these processes. Our embodied brain model can provide a novel computational approach to the mechanistic understanding of cortical learning based on sensorimotor experiences mediated by complex interactions between the body, environment and nervous system.

3 papers giving the Hindu, Catholic and Protestant views on abortion, presented at a seminar for physicians at the Christian Medical College, Vellore, India, January 1972, are summarized. S. THANDAVESWARA stated that the traditional Hindu position, based on the ethical code, Dharma Shastras, prohibits abortion because the practice could prevent rebirth of a specific human life that is in the process of becoming liberated (moksa). Yet an institution, the Parishads, exists to reconsider such matters, and if its membership were not committed to conservative priorities, it could conceivably approve of abortion for the mothers' physical or mental health if she freely chose an abortion. O. DIJKSTRA stated the traditional Catholic view that "direct" abortion is always murder, but "indirect" abortion may be allowed as in removing a cancerous pregnant uterus. He expanded on the phenomenologic interpretation of some liberal theologians, whose views are not yet accepted officially, that the human self emerges irreversibily at nidation, before which abortion could be permitted. The author gave a Protestant position based on Biblical and sociologic sources. He disputed the Catholic's view that human life begins at nidation, and maintained that mere life is only one value to be weighed against love and justice for the fetus, mother, family and society. Love and justice require a choice of contraceptives, safe abortion for all economic classes, safe gestation for future pregnancies, and a resonable hope for a good life for the fetus, its family and society.

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.
Responses to the question as to whether abortions should be performed at the woman's request during the first trimester of pregnancy were evenly divided. There was support for abortion on socioeconomic grounds, during the first trimester, from 61.5% of the respondents. Termination of pregnancy beyond the first trimester was supported by a majority of the respondents only in cases in which the woman's life is in danger (73.9%) or in which there is evidence of a severe physical abnormality in the fetus (70.6%) or in cases in which the woman's physical health is in danger (55.5%). Those who said they would not support abortion under any circumstances constitute, at most, 5.1% of the respondents. Support for the maintenance or the elimination of therapeutic abortion committees was addressed in two questions and in both cases the respondents were evenly divided. The responses to these two questions were compared and found to be logically consistent. Only physicians should perform abortions, and they should be performed in hospitals with the woman either as an inpatient or, during the first trimester, as an outpatient. The performance of first-trimester abortions in provincially approved abortion clinics was supported by 47.3% of the respondents. Of the 885 respondents who wished to see some amendment to the Criminal Code, 409 stated that the term "health" as used in the Criminal Code relative to the legal grounds for therapeutic abortion should be defined.

A key element in cultural and gender power relations surrounding abortion is how women who undergo an abortion are represented in public talk. We analyse how women were named and positioned, and the attendant constructions of abortion, in South African newspaper articles on abortion from 1978 to 2005, a period during which there were radical political and legislative shifts. The name 'woman' was the most frequently used (70% of articles) followed by 'girl/teenager/child' (25%), 'mother' (25%), 'patient' (11%) and 'minor' (6%). The subject positionings enabled by these names were dynamic and complex and were interwoven with the localised, historical politics of abortion. The 'innocent mother' and the bifurcated 'patient' (woman/foetus) positionings were invoked in earlier epochs to promote abortion under medical conditions. The 'dangerous mother' and woman as 'patient' positionings were used more frequently under liberal abortion legislation to oppose and to advocate for abortion, respectively. The positioning of the 'girl/teenager/child' as dependent and vulnerable was used in contradictory ways, both to oppose abortion and to argue for a liberalisation of restrictive legislation, depending on the attendant construction of abortion. The neutral naming of 'woman' was, at times, linked to the liberal imaginary of 'choice'.

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.

Bovine trichomoniasis is a concern for the cattle industry. Advances in testing systems have increased the ability to detect the disease in bulls. However, the greatest limitation is proper collection of an adequate sample. The low repeatability observed with most sample collection techniques can cause false-negative results. The aim of our study was to validate a sample collection technique that increases diagnostic sensitivity and is easier and safer to collect than preputial scraping. Commercial bulls (n = 111) of unknown infection status were sampled for detection of Tritrichomonas foetus using 2 different collection methods: 1) preputial scraping with a dry insemination pipette and 2) penile sponging with a 16-ply gauze sponge. Preputial scraping samples were collected by vigorously scraping preputial and penile mucosa using a rigid insemination pipette while applying negative pressure with a syringe. Penile sponge samples were obtained by swabbing the penile and preputial mucosa with a gauze sponge during full extension of the penis. All samples were processed using a commercial medium and submitted under similar conditions for PCR testing. Positive PCR results were detected in 37 of 111 (33%) bulls using the preputial scraping technique; however, 39 of 111 (35%) were positive using the penile sponging technique. The Newton-Raphson algorithm predicted that the sensitivity of the preputial scraping method was 0.919 (95% CI: 0.689-0.983) and the sensitivity of the penile sponging was 0.949 (95% CI: 0.818-0.987). These data indicate that the penile sponging technique is a reliable alternative to the preputial scraping method.
"Individual and social attitudes toward abortion are unstable," the author notes, as he reviews the history of such attitudes in the United States and Britain. In both countries abortion was legal in 1800, but had become illegal by 1900, largely due to changing attitudes within the medical profession, including the desire to protect the profession against the activities of non-physicians. In the U.S., religious groups took little interset in the issue until late in the 19th century. Today, years after the legalization of abortion in Britain (1967) and the U.S. (1974), there is a chance that public attitudes will be influenced for a second time by a vocal few, again restricting legal access to abortion. The commercial success of MDs who specialize in abortions is a complicating factor, making it easier for opposition groups to recruit supporters. The abortion debate concerns unprovable interpretations of observable facts; it is an exercise in religious toleration. The most important role of physicians is to help establish a liberal and civilized framework within which colleagues of different persuasions can make free and objective choices regarding the delivery of abortion services.

Cows on an alpine pasture were presented with severe signs of vaginitis. To rule out infection with Tritrichomonas foetus, vaginal swabs were taken and real-time PCR based on detection via fluorescence resonance energy transfer (FRET) probes and targeting the first internal transcribed spacer (ITS-1) of nuclear ribosomal DNA (rDNA) was performed. PCR was positive in 25 of totally 34 assessed cows. However, the melting profiles of the probes targeting the diagnostic PCR products differed from the T. foetus positive control. Subsequent sequencing of the amplicons revealed 91% identity to Simplicimonas sp. sequences deposited in GenBank™. Furthermore, there was no clear association between positive PCR result and presence of vaginitis. To investigate the distribution of this Simplicimonas-like organism in cows, more herds grazing on the same alpine pastures as well as unrelated cows were tested. In total, 133 cows and 16 heifers were sampled, 53 cows and 6 heifers even twice. Vaginitis was evident in 43 cows and 4 heifers. All-over-positivity of PCR was 44%, including nine tests performed on heifers. Melting peak analysis indicated Simplicimonas-like organisms in all positive samples. Culture attempts in bovine InPouch ™ TF failed. No association between a positive PCR result and the presence of vaginitis was found. This is, to the best of our knowledge, the first report on Simplicimonas-like DNA in vaginal swabs of female cattle. Our data suggest that when testing vaginal swabs of cattle by means of T. foetus PCR, false positive reactions due to Simplicimonas-like organisms may occur.

Tritrichomonas foetus has been identified as the causative agent of feline intestinal trichomonosis, characterized by clinical signs of chronic large bowel diarrhoea. This disease has been reported in cats from the USA, Europe and Australia. However, its epidemiology is still unclear. The aim of the present study was to describe T. foetus infection in a Persian cattery in Spain. T. foetus infection was sequentially diagnosed in 20 cats by direct faecal smear examined under the microscope, specific culture (In Pouch TF medium) and PCR. A standard coprological sedimentation method was also performed in order to screen for other intestinal parasites in all the cats included. In addition, sera were tested for IgG antibodies against Leishmania infantum, Toxoplasma gondii, and for the detection of feline immunodeficiency virus (FIV) and feline leukaemia virus (FeLV). Five out of 20 cats were positive for T. foetus (25%), two of them by microscopy, culture and PCR and three by culture and PCR. No association was found between T. foetus infection and age or sex. L. infantum and T. gondii seroprevalence rates were 15% and 10%, respectively. The prevalence of FeLV p27 antigen and of FIV antibodies in the study population was zero. Cystoisospora spp. oocysts were detected in one cat. These preliminary results show that the transmission of T. foetus infection in cluster conditions may occur between asymptomatic cats and young or immunocompromised animals.

MECP2 duplication results in a well-recognised syndrome in 100% of affected male children; this syndrome is characterised by severe neurodevelopmental disabilities and recurrent infections. However, no sonographic findings have been reported for affected foetuses, and prenatal molecular diagnosis has not been possible for this disease due to lack of prenatal clinical presentation. In this study, we identified a small duplication comprising the MECP2 and L1CAM genes in the Xq28 region in a patient from a family with severe X-linked mental retardation and in a prenatal foetus with brain structural abnormalities. Using high-resolution chromosome microarray analysis (CMA) to screen 108 foetuses with congenital structural abnormalities, we identified additional three foetuses with the MECP2 duplication. Our study indicates that ventriculomegaly, hydrocephalus, agenesis of the corpus callosum, choroid plexus cysts, foetal growth restriction and hydronephrosis might be common ultrasound findings in prenatal foetuses with the MECP2 duplication and provides the first set of prenatal cases with MECP2 duplication, the ultrasonographic phenotype described in these patients will help to recognise the foetuses with possible MECP2 duplication and prompt the appropriate molecular testing.
An argument is made for applying the principles of evolutionary biology to abortion behavior, based on the idea that long-lasting behavior (including ethical behavior) has a positive selective value which theoretically can be translated into population numbers. The approach verges on utilitarianism; it is argued that such an approach could reduce or avoid the emotionality and subjectivity of arguments for and against induced abortion. Actual application of evolutionary biology principles is limited by the rudimentary present state of behavioral science.
Statistics on legal abortion in Britain between 1968-1974 are presented. There was a mortality rate of 10+ or -2 per 100,000 abortions: 27+ or -11 in 1968-1969, 12+ or -4 in 1970-1972, and 6+ or -3 in 1973-1974. Legal abortion mortality increased from 4+ or -3 when performed at gestation under 9 weeks to 5+ or -2 at 9-12 weeks, 13+ or -7 at 13-16 weeks, and 62+ or -33 at 17 weeks and over. The ratio was 11+ or -6 for women under 20 years of age, increasing to 5+ or -3 at age 20-29, 10+ or -6 at age 30-39, and 23+ or -19 at age 40 and over. The parity had little influence on abortion mortality, but the technique used had a great influence. Hysterotomy, hypertonic saline, and abortifacient paste were the most dangerous, in increasing order, with mortality rates of 39+ or -30, 106+ or -75, and 152+ or -89, respectively. The rates for aspiration and curretage were 4+ or -2 and 4+ or -3, respectively. There was a higher mortality risk with abortion with sterilization. The main causes of legal abortion mortality were infection, pulmonary embolism, and complications of general anesthesia. The high incidence of mortality associated with legal abortion in Britain is partially caused by: 1) high incidence of concurrent sterilization, 2) former use of dangerous techniques, 3) significant incidence of second trimester abortion, 4) routine use of general anesthesia, and 5) previous ill health of some of the women.

This essay offers a moderate view of abortion that imposes a time limit for unrestricted abortion and specific indications for later abortions. The introduction notes that the discussion will provide a defense for this policy based on a moral analysis but that other options for moderates, especially options provided by freestanding views (the defense of which does not rest on any prior commitment about the morality of abortion), will also be considered. The next section considers the moral status of the fetus grounded in a criterion of moral standing that stipulates the necessary characteristics to achieve moral standing. This discussion concludes that a fetus acquires moral standing only when it becomes sentient. Section 3 moves the argument from ethics to politics to prove that a moderate policy must place no limitations on abortion before the time the fetus becomes sentient because before that time the fetus has no interest for the state to protect. The final section notes that some pro-choice advocates may be happier with the moderate policy proposed than with its controversial defense based on the moral status of the fetus and that another defense of a moderate policy could be based on a finding that the ethical issue can not be decided and that no view about abortion ethics is more reasonable than any other. The essay concludes that the ethical debate is ultimately unavoidable.

The hydrogenosome is an unusual organelle found in several trichomonad species and other protists living in oxygen poor or anoxic environments. The hydrogenosome behavior in the protist Tritrichomonas foetus, parasite of the urogenital tract of cattle, is reported here. The hydrogenosomes were followed by light and transmission electron microscopy during the whole cell cycle. Videomicroscopy, immunofluorescence microscopy, and immunocytochemistry were also used. It is shown that the hydrogenosomes divide at any phase of the cell cycle and that the organellar division is not synchronized. During the interphase the hydrogenosomes are distributed mainly along the axostyle and costa, and at the beginning of mitosis migrate to around the nucleus. Three forms of hydrogenosome division were seen: (1). segmentation, where elongated hydrogenosomes are further separated by external membranous profiles; (2). partition, where rounded hydrogenosomes, in a bulky form, are further separated by a membranous internal septum and, (3). a new dividing form: heart-shaped hydrogenosomes, which gradually present a membrane invagination leading to the organelle division. The hydrogenosomes divide at any phase of the cell cycle. A necklace of intramembranous particles delimiting the outer hydrogenosomal membrane in the region of organelle division was observed by freeze-etching. Similarities between hydrogenosomes and mitochondria behavior during the cell cycle are discussed.

Folic acid supplementation can prevent many cases of neural tube defects (NTDs), whereas suboptimal maternal folate status is a risk factor, suggesting that folate metabolism is a key determinant of susceptibility to NTDs. Despite extensive genetic analysis of folate cycle enzymes, and quantification of metabolites in maternal blood, neither the protective mechanism nor the relationship between maternal folate status and susceptibility are understood in most cases. In order to investigate potential abnormalities in folate metabolism in the embryo itself, we derived primary fibroblastic cell lines from foetuses affected by NTDs and subjected them to the dU suppression test, a sensitive metabolic test of folate metabolism. Significantly, a subset of NTD cases exhibited low scores in this test, indicative of abnormalities in folate cycling that may be causally linked to the defect. Susceptibility to NTDs may be increased by suppression of the methylation cycle, which is interlinked with the folate cycle. However, reduced efficacy in the dU suppression test was not associated with altered abundance of the methylation cycle intermediates, s-adenosylmethionine and s-adenosylhomocysteine, suggesting that a methylation cycle defect is unlikely to be responsible for the observed abnormality of folate metabolism. Genotyping of samples for known polymorphisms in genes encoding folate-associated enzymes did not reveal any correlation between specific genotypes and the observed abnormalities in folate metabolism. These data suggest that as yet unrecognized genetic variants result in embryonic abnormalities of folate cycling that may be causally related to NTDs.

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

The objective of this study was to determine the level and duration of IgG antibodies induced against killed whole Tritrichomonas foetus and T foetus-purified surface antigen (TF1.17) in serum, vaginal, and uterine secretions after systemic immunization of beef cows with a vaccine containing killed whole T foetus. Twenty nonpregnant beef cows were randomly assigned to vaccine or control groups as follows: Vaccine (n = 10): cows received 2 mL of a commercial vaccine containing killed whole T foetus subcutaneously and a 2-mL booster 2 weeks later. Control (n = 10): cows received 2 mL of sterile saline on the same schedule. Vaginal secretions and blood samples were collected on Days 0, 8, 15, 22, 29, 36, 43, 50, 60, 75, 89, 110, 146, and 182 relative to day of primary vaccination. Uterine flush fluid was collected on Days 0, 15, 29, and 43 after the day of primary vaccination. Samples were assayed for IgG antibodies to the killed whole T foetus and surface antigen TF1.17 using enzyme-linked immunosorbent assay. Serum whole T foetus-specific IgG levels were significantly increased (between Days 15 and 182) following vaccination with T foetus or with saline. No differences between vaccinates and controls in uterine responses to whole-cell antigen were detected. Serum anti-TF1.17 IgG responses to vaccination were significantly higher than Day 0 throughout the immunization period (P < 0.001) and were higher than responses in control animals on each day post immunization through Day 146 (P < 0.001). A significant rise in TF1.17-specific IgG levels was observed in vaginal and uterine fluids from Day 15 post vaccination compared to the Day 0 levels. These levels remained significantly elevated in vaginal and uterine fluids through Days 75 (P < 0.05) and 43 (P < 0.001) after primary vaccination, respectively. Antibody levels in serum, vaginal, and uterine secretions against TF1.17 remained low in the control group throughout the study. In conclusion, vaccination of

Abstract Oral contraceptives (OCs) following induced abortion offer a reliable method to avoid repeated abortion. However, limited data exist supporting the effective use of OCs postabortion. We conducted this systematic review and meta-analysis in the present study reported immediate administration of OCs or combined OCs postabortion may reduce vaginal bleeding time and amount, shorten the menstruation recovery period, increase endometrial thickness 2 to 3 weeks after abortion, and reduce the risk of complications and unintended pregnancies. A total of 8 major authorized Chinese and English databases were screened from January 1960 to November 2014. Randomized controlled trials in which patients had undergone medical or surgical abortions were included. Chinese studies that met the inclusion criteria were divided into 3 groups: administration of OC postmedical abortion (group I; n = 1712), administration of OC postsurgical abortion (group II; n = 8788), and administration of OC in combination with traditional Chinese medicine postsurgical abortion (group III; n = 19,707). In total, 119 of 6160 publications were included in this analysis. Significant difference was observed in group I for vaginal bleeding time (P = 0.0001), the amount of vaginal bleeding (P = 0.03), and menstruation recovery period (P < 0.00001) compared with the control groups. Group II demonstrated a significant difference in vaginal bleeding time (P < 0.00001), the amount of vaginal bleeding (P = 0.0002), menstruation recovery period (P < 0.00001), and endometrial thickness at 2 (P = 0.003) and 3 (P < 0.00001) weeks postabortion compared with the control group. Similarly, a significant difference was observed in group III for reducing vaginal bleeding time (P < 0.00001) and the amount of vaginal bleeding (P < 0.00001), shortening the menstruation recovery period (P < 0.00001), and increasing endometrial thickness 2 and 3 weeks after surgical abortion (P < 0

Various ethical and practical aspects concerning induced abortion are discussed. Arguments against abortion can be enumerated on many levels. The unborn fetus has a worth of its own, but it also has a value for the parents and the society as a whole. Guilt feelings can occur in women who undergo induced abortion, and the possibility of complications of the operation must be taken into consideration. Abortion can also cause stress in the physician who performs it and in the partner of the abortion patient. The costs of abortion are paid by society through insurance costs. Abortion can damage the ethical conscience of the abortion patient, the physician who performs the operation, and in the society which allows it. Ethical considerations involved with abortion are also expounded. Induced abortion is a process whereby life is weighed against other considerations. Ethical conscience involves the ability to differentiate between degrees of possible communication, which would differentiate the life of the embryo from that of a retarded child, for example. Guilt feelings are rooted in ethical considerations. The capability for independent existence is the principle ethical boundary involved in determining when abortion is to be permitted. Eugenic abortion is a separate ethical consideration. A schema of practical guidelines for considerations and indications for performing abortions is presented.

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

The 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

This study uses pooled cross-section time-series data, over the years 1982, 1992 and 2000, to estimate the impact of various restrictive abortion laws on the demand for abortion. This study complements and extends prior research by explicitly including the price of obtaining an abortion in the estimation. The empirical results show that the real…

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.
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.

Abortive initiation, when first discovered, was an enigmatic phenomenon, but fully three decades hence, it has been shown to be an integral step in the transcript initiation process intimately tied to the promoter escape reaction undergone by RNA polymerase at the initiation-elongation transition. A detailed understanding of abortive initiation-promoter escape has brought within reach a full description of the transcription initiation mechanism. This enormous progress was the result of convergent biochemical, genetic, and biophysical investigations propelled by parallel advances in quantitation technology. This chapter discusses the knowledge gained through the biochemical approach and a high-resolution method that yields quantitative and qualitative information regarding abortive initiation-promoter escape at a promoter.

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

In 2001, the first case of bovine chlamydial abortion was reported in canton Graubunden, Switzerland. In this region, Chlamydophila (Cp.) abortus is endemic in small ruminants. Hence, we aimed to investigate the incidence of chlamydia-related abortions in cattle from Graubunden. During breeding seasons of 2003-2004, formalin-fixed and paraffin-embedded placenta specimens (n = 235) from late-term abortions in cattle were analyzed by histopathology, immunohistochemistry with a Chlamydiaceae-specific monoclonal antibody against chlamydial lipopolysaccharide (LPS), and 2 different polymerase chain reaction (PCR) methods (16 S ribosomal ribonucleic acid [rRNA] PCR, intergenic spacer [IGS-S] PCR), followed by PCR product sequencing. In 149 of 235 cases (63.4%), histopathologic lesions such as purulent and/or necrotizing placentitis were observed. Chlamydial antigen was clearly demonstrated in immunohistochemistry in only 1 of 235 cases (0.4%). Cp. abortus or Cp. psittaci was found in 12 of 235 (5.1%) and 10 of 235 cases (4.2%) by 16 S rRNA PCR and IGS-S PCR, respectively. However, we detected, by 16 S rRNA PCR, 43 of 235 cases (18.3%) to be positive for chlamydia-like organisms. In contrast to the situation in small ruminants in the canton Graubunden, bovine abortion from Cp. abortus seems not to play an important role. Nevertheless, zoonotic potential should be taken into account when handling abortion material from cattle. The significance of chlamydia-like isolates other than Waddlia chondrophila remains an open question in abortion and needs further investigation.

In this work, a high-speed imaging platform and a resistive force theory (RFT) based model were applied to investigate multi-flagellated propulsion, using Tritrichomonas foetus as an example. We discovered that T. foetus has distinct flagellar beating motions for linear swimming and turning, similar to the 'run and tumble' strategies observed in bacteria and Chlamydomonas. Quantitative analysis of the motion of each flagellum was achieved by determining the average flagella beat motion for both linear swimming and turning, and using the velocity of the flagella as inputs into the RFT model. The experimental approach was used to calculate the curvature along the length of the flagella throughout each stroke. It was found that the curvatures of the anterior flagella do not decrease monotonically along their lengths, confirming the ciliary waveform of these flagella. Further, the stiffness of the flagella was experimentally measured using nanoindentation, allowing for calculation of the flexural rigidity of T. foetus's flagella, 1.55×10(-21) N m(2). Finally, using the RFT model, it was discovered that the propulsive force of T. foetus was similar to that of sperm and Chlamydomonas, indicating that multi-flagellated propulsion does not necessarily contribute to greater thrust generation, and may have evolved for greater manoeuvrability or sensing. The results from this study have demonstrated the highly coordinated nature of multi-flagellated propulsion and have provided significant insights into the biology of T. foetus.

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
Informed consent mandates for abortion providers may infringe the First Amendment's freedom of speech. On the other hand, they may reinforce the physician's duty to obtain informed consent. Courts can promote both doctrines by ensuring that compelled physician speech pertains to medical facts about abortion rather than abortion ideology and that compelled speech is truthful and not misleading.
Changes in homicide and arrest rates were compared among cohorts born before and after legalization of abortion and those who were unexposed to legalized abortion. It was found that legalized abortion improved the lives of many women as they could avoid unwanted births.

The dielectric properties of rat embryos/foetuses have been acquired at several stages of gestation at 37 °C and in the frequency range of 40 MHz-20 GHz. Measurements were carried out on homogenized tissues, as trial experiments did not show any systematic difference between the dielectric data of intact and homogenized tissues at microwave frequencies. The results showed that dielectric properties of the foetus are generally higher than adult muscle and brain. The measured data also showed some decline for both permittivity and conductivity as the foetus grew from 18 to 20 days old; however, these changes were not statistically significant. Data were also collected for placenta and amniotic fluid which were in good agreement with those recently obtained from human tissues. Finally, tabulated numerical dielectric data for rat foetal tissues are presented for a wide range of medical and telecommunication frequencies.

Caplan, Arthur L
The shortage of organs and tissues for transplantation in infants is particularly severe. Caplan considers the moral and public policy implications of utilizing abortuses and brain dead or anencephalic infants as donors. Arguments favoring their use include the potential benefits for research, benefits to existing infants born with fatal conditions, the ethical cost of relying on primates as sources of organs, and the providing of solace to grieving parents. Arguments against their use include the potential for coercion or conflict of interest in parental decisions about donation, the possibility that abortion may be encouraged, the fact that brain death is difficult to diagnose in infants while organ procurement from anencephalics may be considered murder, and the charge that an increase in infant transplants would be too costly. Caplan concludes that the arguments for using abortuses, anencephalics, and brain dead infants as organ and tissue donors outweigh the arguments against.
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.

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

Despite Zambia's relatively progressive abortion law, women continue to seek unsafe, illegal abortions. Four domains of abortion attitudes - support for legalization, immorality, rights, and access to services - were measured in 4 communities. A total of 668 people were interviewed. Associations among the 4 domains were inconsistent with expectations. The belief that abortion is immoral was widespread, but was not associated with lack of support for legalization. Instead, it was associated with belief that women need access to safe services. These findings suggest that increasing awareness about abortion law in Zambia may be important for encouraging more favorable attitudes.

A metabolic labelling medium was devised for Trichomonas vaginalis and Tritrichomonas foetus utilizing 35S methionine. T. vaginalis cultured for 24h in the medium took up approximately 27% of the available label and increased greater than two fold in number. Counts per microgram of protein were 32,555 +/- 10% between different strains or identical strains in different labelling runs. T. foetus took up approximately 5% of the available label and increased greater than two fold in 24h. This resulted in specific labelling of 12,704 cpm/ug protein +/- 10% between different runs with the same strain.
Notably absent from the public debate on abortion in Ireland have been the voices of women who have experienced induced abortion. Interviews with six acquaintances of the author who underwent abortion identified four themes underlying women's post-abortion silence. First, women fear public condemnation and personal rejection. Second, women are concerned that any emotional ambivalence they express about the abortion experience will be misconstrued as anti-abortion sentiment. Third, women worry that speaking out about their experience would be upsetting to friends and family. Fourth, women report frustration about the lack of a suitable public forum for voicing the complexities inherent in the abortion issue. The women's perception that their experience did not fit neatly with the rhetoric of either pro- or anti-abortion groups caused them to feel alienated from a political discourse that tends to depersonalize abortion. Although none of the women regretted the abortion decision, they continued to struggle with unresolved conflicts over taking responsibility for ending some form of life. A cycle has been created in which women do not feel safe to discuss their personal experiences until a more favorable political climate exists, yet the public perception of abortion is unlikely to change until more women's voices are heard. Feminist leaders are urged to address this dilemma.

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

OBJECTIVE To investigate the effects of specific cysteine protease (CP) inhibitors on cytopathic changes to porcine intestinal epithelial cells induced by Tritrichomonas foetus isolated from naturally infected cats. SAMPLE T foetus isolates from 4 naturally infected cats and nontransformed porcine intestinal epithelial cells. PROCEDURES T foetus isolates were treated with or without 0.1 to 1.0mM of the CP inhibitors antipain, cystatin, leupeptin, and chymostatin and the vinyl sulfone inhibitors WRR-483 and K11777. In-gel gelatin zymography was performed to evaluate the effects of these inhibitors on CP activity of T foetus isolates. Each treated or untreated isolate was also cocultured with monolayers of porcine intestinal epithelial cells for 24 hours, and cytopathic effects of T foetus were evaluated by light microscopy and crystal violet spectrophotometry. RESULTS Results of in-gel gelatin zymography suggested an ability of WRR-483, K11777, and cystatin to target specific zones of CP activity of the T foetus isolates. These inhibitors had no effect on T foetus growth, and the cytopathic changes to the intestinal epithelium induced by all 4 T foetus isolates were significantly inhibited. CONCLUSIONS AND CLINICAL RELEVANCE This study revealed that certain protease inhibitors were capable of inhibiting regions of CP activity (which has been suggested to cause intestinal cell damage in cats) in T foetus organisms and of ameliorating T foetus-induced cytopathic changes to porcine intestinal epithelium in vitro. Although additional research is needed, these inhibitors might be useful in the treatment of cats with trichomonosis.

Voluntarily induced abortion has been under permanent dispute and legal regulations, because societies invariably condemn extramarital pregnancies. 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.

Unsafe abortions refer to terminations of unintended pregnancies by persons lacking the necessary skills, or in an environment lacking the minimum medical standards, or both. Globally, unsafe abortions account for 67,900 maternal deaths annually (13% of total maternal mortality) and contribute to significant morbidity among women, especially in under-resourced settings. The determinants of unsafe abortion include restrictive abortion legislation, lack of female empowerment, poor social support, inadequate contraceptive services and poor health-service infrastructure. Deaths from unsafe abortion are preventable by addressing the above determinants and by the provision of safe, accessible abortion care. This includes safe medical or surgical methods for termination of pregnancy and management of incomplete abortion by skilled personnel. The service must also include provision of emergency medical or surgical care in women with severe abortion complications. Developing appropriate services at the primary level of care with a functioning referral system and the inclusion of post abortion contraceptive care with counseling are essential facets of abortion care.

This study examines the association between religion and attitudes toward the practice of abortion and abortion policy in Brazil. Drawing upon data from the 2002 Brazilian Social Research Survey (BSRS), we test a number of hypotheses with regard to the role of religion on opposition to the practice of abortion and its legalization. Findings indicate that frequently attending Pentecostals demonstrate the strongest opposition to the practice of abortion and both frequently attending Pentecostals and Catholics demonstrate the strongest opposition to its legalization. Additional religious factors, such as a commitment to biblical literalism, were also found to be significantly associated with opposition to both abortion issues. Ultimately, the findings have implications for the future of public policy on abortion and other contentious social issues in Brazil.
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.

The pineal gland is an organ involved in regulation of homeostasis and body rhythms. It plays an important role in the growth foetuses and adaptation of newborns to new environmental conditions. The requirements of foetuses and newborns progressively change during development. The purpose of the study was to evaluate morphological changes of pineal glands in foetuses and infants with brain lesions. The results of our study showed that parenchyma of developing pineal glands was susceptible to injury in most autopsied foetal and infantile cases. Morphological changes in pineal glands were found in 90% of autopsied brains but 100% of the cases had infections. The lesions in the pineal included mainly haemorrhagic, necrotic and cystic changes. In our autopsied foetuses and children, morphological changes in pineal glands were concomitant with various lesions of brain parenchyma. All results of our study lead to the conclusion that the pineal gland during its development is very susceptible to injury. The failure of normal pineal gland development and subsequent impaired production of melatonin decrease resistance of newborns and children to various environmental harmful agents.

Trichomonads are a group of anaerobic flagellates. Two species of intestinal trichomonads have been described in cats - pathogenic Tritrichomonas foetus and probably harmless Pentatrichomonas hominis. InPouch™ TF-Feline medium (Bio-Med Diagnostics, White City, Oregon, USA) is considered the gold standard for diagnosis of T. foetus infection in cats. It is commercially available, relatively cheap and easy-to-use. The medium is intended to be highly specific to T. foetus as morphologically similar Pentatrichomonas hominis and Giardia sp. do not survive here longer than 24h. In this study we successfully cultivated P. hominis in InPouch™ TF-Feline medium for 3 days after inoculation with cat faeces. The identity of the organism was assessed by sequencing of SSU rDNA and ITS region. Possible coinfection with T. foetus was ruled out using Tritrichomonas-specific PCR. Our results suggest possible misdiagnosis of tritrichomonosis in cats using InPouch™ TF-Feline medium. PCR-based verification of culture-positive samples prior the potentially neurotoxic ronidazole treatment is recommended.

This essay seeks to reveal the weakness in arguments against public funding of abortions and abortion counseling in the US based on economic, ethico-religious, anti-racist, and logical-consistency objections and to show that public funding of abortion is strongly supported by appeals to basic human rights, to freedom of speech, to informed consent, to protection from great harm, to justice, and to equal protection under the law. The first part of the article presents the case against public funding with detailed considerations of the economic argument, the ethico/religious argument, the argument that such funding supports racist genocide or eugenic quality control, and arguments that a logical inconsistency exists between the principles used to justify the legalization of abortions and arguments for public funding. The second part of the article presents the case for public funding by discussing the spending of public funds on morally offensive programs, arguments for public funding of abortion counseling for the poor, and arguments for public funding of abortions for the poor. It is concluded that it is morally unacceptable and rationally unjustifiable to refuse to expend public funds for abortions for low income women, because after all most money for legal abortions for the poor comes from welfare payments made to women. If conservative forces want to insure that no public funds pay for abortions, they must stop all welfare payments to pregnant women.

Bovine viral diarrhoea virus (BVDV) has a unique capacity to cause persistent infections of foetuses exposed within the first 150 days of gestation. Preventing foetal BVDV infection will aid in improved control. This unique ability gives BVDV a selective advantage allowing continual mutation and antigenic variation within cattle populations. Therefore, BVDV has become widespread and causes economic losses due to respiratory, reproductive and enteric disease. Vaccination (modified-live or killed) can provide some protection from acute disease and the development of persistently infected foetuses. However, vaccination programmes alone cannot control or eliminate BVDV. In naturally exposed and vaccinated herds, BVDV infections are not self-limiting and may persistent over time. This underscores the ability of the BVDV genome to remain fluid and adapt under selective pressures. Factors influencing persistence of BVDV infections in cattle populations include: non-lytic infections; evasion of host immune responses; foetal infections; acute infections; management practices; contaminated biologics; secondary hosts; defective replicated intermediates; antigenic variation; and replication in privileged anatomical sites.

The stability of abortion opinions suggests that pre-adult factors influence these attitudes more than contemporaneous political events. Surprisingly, however, we know little about the origins of abortion opinions, no doubt because the majority of research focuses on cross-sectional analyses of patterns across cohorts. We use a developmental model that links familial and contextual factors during adolescence to abortion attitudes years later when respondents are between 21 and 38 years old. Findings show that religious adherence and maternal gender role values are significant predictors of adult abortion opinions, even after controlling for contemporaneous religious adherence and the respondents’ own views on gender roles. Adolescent religious adherence matters more than religious denomination for adult abortion attitudes. The results have important implications for future trends in abortion attitudes in light of declining religiosity among Americans. PMID:27257307
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.

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.

Bovine viral diarrhea (BVD) is one of the greatest challenges for breeding and commercial livestock. It is characterized by lesions of the respiratory and gastrointestinal tract, abortion, infertility, immune deficiency, and persistence of the pathogen. In this work, a set of measures for the rehabilitation and prevention of BVD in cattle is described. It includes the data of the literature, guidance documents for the diagnosis and control of BVD adopted by OIE, EU countries, USA, as well as the results of this research.

The national security implications of abortion have not been addressed in a public forum but could come to be the single most important facet of the abortion debate. Abortion has been and will continue to be an essential variable in fertility control. Any serious effort at population growth control in the next few decades will have to recognize the role abortion has in birth rate decline. At this time an estimated 40-50 million abortions are performed worldwide each year; 1/2 of them are illegal. In the absence of abortion, annual growth would approach approximately 120 million. Growth of this magnitude would probably place intolerable strains on the economics and environments of some nations. To recognize the role of abortion in fertility control is to emphasize the inescapable need for abortion as 1 element in any comprehensive family planning service. Excessive population growth leads to chronic unemployment and the frustration of the goals of hundreds of millions of people. While this new threat to the security of individual nations and ultimately to global security has not been widely acknowledged, it is beginning to gain the attention of people of different professions and distinctive political persuasions. In many ways, rampant population growth is an even more dangerous and subtle threat to the world than thermonuclear war, for it is intrinsically less subject to rational safeguards and less amenable to organized control. Possibly the greatest and most pervasive problem is the declining ability to meet human needs in the areas of food, raw material, and resources, counterpoised against what are clearly rising expectations of growing populations. The following facts cannot be disputed: world population is a threat to the security of all nations, including the U.S.; abortion is essential to any effective population growth control effort; abortion is a national security issue; and as the availability of legal abortion in the U.S. goes, so goes the availability

A female Catholic theologian imagines a just society that does not judge women who decide to undergo an abortion. The Church, practitioners, and the courts must trust that women do make person-enhancing choices about the quality of life. In the last 15 years most progress in securing a woman's right to abortion has been limited to white, well-educated, and middle or upper middle class women. A just society would consider reproductive options a human right. Abortion providers are examples of a move to a just society; they are committed to women's well-being. There are some facts that make one pessimistic about achieving abortion in a just society. The US Supreme Court plans to review important decisions establishing abortion as a civil right. Further, some men insist on suing women who want to make their own reproductive decisions--an anti-choice tactic to wear away women's right to reproductive choice. Bombings of abortion clinics and harassment campaigns by anti-choice groups are common. These behaviors strain pro-choice proponents emotionally, psychically, and spiritually. Their tactics often lead to theologians practicing self-censorship because they fear backlash. Abortion providers also do this. Further, the reaction to AIDS is that sex is bad. Anti-abortion groups use AIDS to further their campaigns, claiming that AIDS is a punishment for sex. Strategies working towards abortion in a just society should be education and persuasion of policymakers and citizens about women's right to choose, since they are the ones most affected by abortion. Moreover, only women can secure their rights to abortion. In a just society, every health maintenance organization, insurance company, and group practice would consider abortion a normal service. A just society provides for the survival needs of the most marginalized.
An attempt is made to identify and document the problems of comparative evaluation of the more recent studies of psychiatric morbidity after abortion and to determine the current consensus so that when the results of the joint RCGP/RCOG study of the sequelae of induced abortion become available they can be viewed in a more informed context. The legalization of abortion has provided more opportunities for studies of subsequent morbidity. New laws have contributed to the changing attitudes of society, and the increasing acceptability of the operation has probably influenced the occurrence of psychiatric sequelae. The complexity of measuring psychiatric sequelae is evident from the many terms used to describe symptomatology and behavioral patterns and from the number of assessment techniques involved. Numerous techniques have been used to quantify psychiatric sequelae. Several authors conclude that few psychiatric problems follow an induced abortion, but many studies were deficient in methodology, material, or length of follow-up. A British study in 1975 reported a favorable outcome for a "representative sample" of 50 National Health Service patients: 68% of these patients had an absence of or only mild feelings of guilt, loss, or self reproach and considered abortion as the best solution to their problem. The 32% who had an adverse outcome reported moderate to severe feelings of guilt, regret, loss, and self reproach, and there was evidence of mental illness. In most of these cases the adverse outcome was related to the patient's environment since the abortion. A follow-up study of 126 women, which compared the overall reaction to therapeutic abortion between women with a history of previous mild psychiatric illness and those without reported that a significantly different emotional reaction could not be demonstrated between the 2 groups. In a survey among women seeking an abortion 271 who were referred for a psychiatric opinion regarding terminations of pregnancy

US anti-abortion groups have used misinformation on the long-term psychological impact of induced abortion to advance their position. This article reviews the available research evidence on the definition, history, cultural context, and emotional and psychiatric sequelae of induced abortion. Notable has been a confusion of normative, transient reactions to unintended pregnancy and abortion (e.g., guilt, depression, anxiety) with serious mental disorders. Studies of the psychiatric aspects of abortion have been limited by methodological problems such as the impossibility of randomly assigning women to study and control groups, resistance to follow-up, and confounding variables. Among the factors that may impact on an unintended pregnancy and the decision to abort are ongoing or past psychiatric illness, poverty, social chaos, youth and immaturity, abandonment issues, ongoing domestic responsibilities, rape and incest, domestic violence, religion, and contraceptive failure. Among the risk factors for postabortion psychosocial difficulties are previous or concurrent psychiatric illness, coercion to abort, genetic or medical indications, lack of social supports, ambivalence, and increasing length of gestation. Overall, the literature indicates that serious psychiatric illness is at least 8 times more common among postpartum than among postabortion women. Abortion center staff should acknowledge that the termination of a pregnancy may be experienced as a loss even when it is a voluntary choice. Referrals should be offered to women who show great emotional distress, have had several previous abortions, or request psychiatric consultation.

Proteasomes are intracellular complexes that control selective protein degradation in organisms ranging from Archaea to higher eukaryotes. These structures have multiple proteolytic activities that are required for cell differentiation, replication and maintaining cellular homeostasis. Here, we document the presence of the 20S proteasome in the protist parasite Tritrichomonas foetus. Complementary techniques, such as a combination of whole genome sequencing technologies, bioinformatics algorithms, cell fractionation and biochemistry and microscopy approaches were used to characterise the 20S proteasome of T. foetus. The 14 homologues of the typical eukaryotic proteasome subunits were identified in the T. foetus genome. Alignment analyses showed that the main regulatory and catalytic domains of the proteasome were conserved in the predicted amino acid sequences from T. foetus-proteasome subunits. Immunofluorescence assays using an anti-proteasome antibody revealed a labelling distributed throughout the cytosol as punctate cytoplasmic structures and in the perinuclear region. Electron microscopy of a T. foetus-proteasome-enriched fraction confirmed the presence of particles that resembled the typical eukaryotic 20S proteasome. Fluorogenic assays using specific peptidyl substrates detected presence of the three typical peptidase activities of eukaryotic proteasomes in T. foetus. As expected, these peptidase activities were inhibited by lactacystin, a well-known specific proteasome inhibitor, and were not affected by inhibitors of serine or cysteine proteases. During the transformation of T. foetus to endoflagellar form (EFF), also known as pseudocyst, we observed correlations between the EFF formation rates, increases in the proteasome activities and reduced levels of ubiquitin-protein conjugates. The growth, cell cycle and EFF transformation of T. foetus were inhibited after treatment with lactacystin in a dose-dependent manner. Lactacystin treatment also resulted in

An aborted fetus of 7 months gestation, the associated placenta, and a single blood sample from the dam were submitted for diagnostic investigation to the diagnostic laboratory of the Lombardy and Emilia-Romagna Experimental Zooprophylactic Institute in Parma, Italy. The serum was negative for Neospora caninum, Coxiella burnetii, Chlamydophila abortus, Bovine herpesvirus 1 (BHV-1), Bovine viral diarrhea virus (BVDV), Brucella abortus, and Brucella melitensis. Fetal tissues and placental cotyledons were pooled and tested by polymerase chain reaction (PCR) for the presence of BHV-1, Bovine herpesvirus 4, BVDV, N. caninum, C. burnetii, Chlamydophila spp., Schmallemberg virus, and Leptospira interrogans. All PCR assays were negative. Bacteriological examinations performed on the fetal organs revealed a pure growth of Staphylococcus lugdunensis in all organs cultured. In human beings, S. lugdunensis is responsible for community-acquired and nosocomial infections, in both immunocompetent and immunocompromised patients. In veterinary medicine, the pathogenic potential of S. lugdunensis has not been fully investigated. The incidence of S. lugdunensis is regarded as being underreported because it could be easily misidentified as Staphylococcus aureus. The current report documents the ability of S. lugdunensis to cause abortion in cattle, indicating the need for accurate diagnostic procedures to identify this emerging and zoonotic pathogen whose incidence is likely underestimated in both human and veterinary medicine.

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.

A number of questions relating to providing abortion information to teenagers can be raised from legal, ethical and philosophical standpoints. The purpose of this article is to examine abortion information-giving from the perspective of counseling and guidance theory and practice. (Author)
Abortion is illegal in Nigeria except to save a woman's life. It is also common, and most procedures are performed under unsafe, clandestine conditions. In 1996, an estimated 610,000 abortions occurred (25 per 1,000 women of childbearing age), of which 142,000 resulted in complications severe enough to require hospitalization. The number of abortions is estimated to have risen to 760,000 in 2006. Unsafe abortions are a major reason Nigeria's maternal mortality rate--1,100 deaths per 100,000 live births--is one the world's highest. According to conservative estimates, more than 3,000 women die annually in Nigeria as a result of unsafe abortion.

This article presents current estimates of the number, rate, and proportion of abortions for all countries which make such data available. 76% of the world's population lives in countries where induced abortion is legal at least for health reasons. Abortion is legal in almost all developed countries. Most developing countries have some laws against abortion, but it is permitted at least for health reasons in the countries of 67% of the developing world's population. The other 33%--over 1 billion persons--reside mainly in subSaharan Africa, Latin America, and the most orthodox Muslim countries. By the beginning of the 20th century, abortion had been made illegal in most of the world, with rules in Africa, Asia, and Latin America similar to those in Europe and North America. Abortion legislation began to change first in a few industrialized countries prior to World War II and in Japan in 1948. Socialist European countries made abortion legal in the first trimester in the 1950s, and most of the industrialized world followed suit in the 1960s and 1970s. The worldwide trend toward relaxed abortion restrictions continues today, with governments giving varying reasons for the changes. Nearly 33 million legal abortions are estimated to be performed annually in the world, with 14 million of them in China and 11 million in the USSR. The estimated total rises to 40-60 million when illegal abortions added. On a worldwide basis some 37-55 abortions are estimated to occur for each 1000 women aged 15-44 years. There are probably 24-32 abortions per 100 pregnancies. The USSR has the highest abortion rate among developed countries, 181/1000 women aged 15-44, followed by Rumania with 91/1000, many of them illegal. The large number of abortions in some countries is due to scarcity of modern contraception. Among developing countries, China apparently has the highest rate, 62/1000 women aged 15-44. Cuba's rate is 59/1000. It is very difficult to calculate abortion rates in countries

The objective was to study the morphology of the articular disc and analyse the immunohistochemical expression of types I and III collagen markers in the temporomandibular joint (TMJ) disc of human foetuses of different gestational ages. Twenty TMJ from human foetuses supplied by Universidade Federal de Uberaba with gestational ages from 17 to 24 weeks were studied. The gestational age of the foetuses was determined by measuring the crown-rump (CR) length. Macroscopically, the foetuses were fixed in 10% formalin solution and dissected by removing the skin and subcutaneous tissue and exposing the deep structures. Immunohistochemical markers of type I and III were used to characterize the existence of collagen fibres. Analysis of the immunohistochemical markers of types I and III collagen revealed the presence of heterotypical fibril networks. PMID:22073371

Trichomonas vaginalis causes vaginitis and increases the risk of HIV transmission by heterosexual sex, while Tritrichomonas foetus causes premature abortion in cattle. Our goals were to determine the effects, if any, of anti-retroviral lectins, which are designed to prevent heterosexual transmission of HIV, on adherence of Trichomonas to ectocervical cells and on Tritrichomonas infections in a mouse model. We show that Trichomonas Asn-linked glycans (N-glycans), like those of HIV, bind the mannose-binding lectin (MBL) that is part of the innate immune system. N-glycans of Trichomonas and Tritrichomonas bind anti-retroviral lectins (cyanovirin-N and griffithsin) and the 2G12 monoclonal antibody, each of which binds HIV N-glycans. Binding of cyanovirin-N appears to be independent of susceptibility to metronidazole, the major drug used to treat Trichomonas. Anti-retroviral lectins, MBL, and galectin-1 cause Trichomonas to self-aggregate and precipitate. The anti-retroviral lectins also increase adherence of ricin-resistant mutants, which are less adherent than parent cells, to ectocervical cell monolayers and to organotypic EpiVaginal tissue cells. Topical application of either anti-retroviral lectins or yeast N-glycans decreases by 40 to 70% the recovery of Tritrichomonas from the mouse vagina. These results, which are explained by a few simple models, suggest that the anti-retroviral lectins have a modest potential for preventing or treating human infections with Trichomonas.

The literature concerning psychosocial aspects of induced abortion is reviewed. Key areas discussed are: the legal context of abortion in Britain, psychological characteristics of abortion-seekers, pre- and post-abortion contraceptive use, pre- and post-abortion counselling, the actual abortion and the effects of termination versus refused abortion. Women seeking termination are found to demonstrate more psychological disturbance than other women, however this is probably temporary and related to the short-term stresses of abortion. Inadequate contraception is frequent prior to abortion but improves afterwards. Few women find the decision to terminate easy and most welcome opportunities for non-judgemental counselling. Although some women experience adverse psychological sequelae after abortion the great majority do not. In contrast, refused abortion often results in psychological distress for the mother and an impoverished environment for the ensuing offspring.

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

The aim of this study was to describe two events in which Neospora caninum was involved in bovine abortions in beef cattle. In the first event, 11 abortions in 57 heifers were recorded in 45 days. One aborted heifer was 5 times more likely to be seropositive than a non-aborted heifer (OR=4.9; IC 1.2-19.9) (p<0.05). In the second event, no association between serological results and abortions were observed (OR=0,69; 0,06-7,31) (p>0.05). Neither antibodies nor isolation of other pathogens were achieved in any case. On the contrary, antibodies and pathognomonic histopathological lesions were observed in the four fetuses from both cases. Interestingly, the findings in the first event suggest the epidemic behavior of the disease. In contrast, in the second event it appears that few abortions were due to N. caninum, suggesting the presence of endemic neosporosis.
In 1987, 20,830 legal abortions were performed in Denmark. 2,845 involved women below the age of 20, and 532 involved women terminating pregnancy after the 12th week. Danish law permits all of its female citizens to have an abortion free-of-charge before the 12th week of pregnancy. After the 12th week, the abortion must be applied for through a committee of 3 members, and all counties in Denmark have a committee. It is felt in Denmark that a woman has a right to an abortion if she decides to have one. It she makes that choice, doctors and nurses are supportive. Since 1970, sex education has been mandatory in Danish schools. Teachers often collaborate closely with school doctors and nurses in this education. All counties are required to have at least 1 clinic that provides contraceptive counselling. It was recently found that the lowest number of pregnancies among teenaged girls was found in a county in Jutland where all 9th grade students visit the county clinic to learn about contraceptives, pregnancy, and abortion. Within 1 year after Copenhagen had adopted this practice, the number of abortions among teenagers declined by 20%. One fourth of all pharmacies also collaborate with schools to promote sex education, instructing students about contraceptives and pregnancy tests. The Danish Family Planning Association has produced a film on abortion, and plans to produce videos on abortion for use in schools. The organization also holds training programs for health care personnel on contraception, pregnancy, and abortion. By means of the practices described above, it is hoped that the number of abortions and unwanted pregnancies in Denmark will be reduced.

Disruption in early pregnancy can cause severe and multiple congenital anomalies in a foetus. Three sequences, Limb-body wall complex (LBWC), amniotic band sequence (ABS) and body-stalk anomaly (BSA) are thought to be caused by disruption. This case report describes a foetus with severe multiple congenital anomalies, that fit the diagnoses of all three sequences, which might advocate these syndromes are a spectrum of one sequence.

The sensitivity (Se) and specificity (Sp) of different testing schemes were estimated for detecting Tritrichomonas foetus (T. foetus) in smegma samples from experimentally infected bulls. Culture and polymerase chain reaction (PCR) on smegma samples were evaluated alone and in parallel testing. Mature dairy bulls (n=79) were intrapreputially inoculated with T. foetus (n=19); Campylobacter (C.) fetus venerealis (n=13); both T. foetus and C. fetus venerealis (n=11); Tetratrichomonas spp. (n=9); C. fetus fetus (n=8); or were not inoculated (n=19). For each bull, smegma samples were collected for 6 week post-inoculation and tested for T. foetus by In Pouch TF culture and PCR. Most T. foetus-inoculated bulls became infected, according to culture (86.7%), PCR (90.0%), and both tests together (93.3%). In T. foetus-inoculated bulls, both tests combined in parallel on a single sample had a Se (78.3%) and Sp (98.5%) similar to two cultures (Se 76.0%, Sp 98.5%) or two PCR (Se 78.0%, Sp 96.7%) sampled on consecutive weeks. The PCR on three consecutive weekly samples (Se 85.0%, Sp 95.4%) and both tests applied in parallel on three consecutive weekly samples (Se 87.5%, Sp 95.6%) were similar to the current gold-standard of six weekly cultures (Se 86.7% and Sp 97.5%). Both tests used in parallel six times had the highest Se (93.3%), with similar Sp (92.5%). Tetratrichomonas spp. were only sporadically detected by culture or PCR. In conclusion, we have proposed alternative strategies for T. foetus diagnostics (for the AI industry), including a combination of tests and repeat testing strategies that may reduce time and cost for bull surveillance.

Foeticide and the abandonment of newborns are important, albeit frequently neglected, issues. Concealment of childbirth is often seen in the setting of unwanted pregnancy which has been recognised as one of the most important factors in both cases. This study highlights the medico-legal autopsy findings of 238 abandoned foetuses and newborns over a period of 17 years (1996-2012) from the region of South Delhi, India. There was no sex predilection. The majority of the cases were full term. Nearly 35% of the foetuses were still born, about 29% were live born and the remainder were non-viable. Among the live born, death by homicide was more common than a natural death and most were left by the roadside. The abandoning and killing of newborns needs urgent attention, and strict measures are needed to save thousands of innocent lives.

Skin is an important barrier protecting the organism against external environmental factors. Determination of its mechanical characteristics as regards its structure has significant scientific and application value. In this work, uniaxial tensile tests were conducted to determine the basic mechanical parameters of skin with respect to its structure. The subject of the study were skin samples taken from domestic pig foetuses. They were excised from different parts of body, in the direction parallel to the long axis of the body. Regardless of the sampling site, the tests revealed no significant differences in the values of the maximum tensile strength (2.08 ± 0.25 MPa) and the conventional Young's modulus (5.87 ± 1.52 MPa). The mechanical and structural tests confirmed that regardless of the sampling region the skin of domestic pig foetuses may constitute a human skin substitute model.

Tritrichomonas foetus is a protozoan parasite that has been recently identified as a causative agent of chronic diarrhea in domestic cats. Transmission of infection occurs by the fecal-oral route through direct contact among animals. Consequently, feline trichomonosis (FT) is more likely to be present in multi-cat environments. The objective of this work was to study the presence of T. foetus and some associated risk factors in cats from densely housed origins and with a reported history of chronic diarrhea. Animals enrolled in this study were family cats (n=15) acquired from pet shops, shelters or breeding centers and cattery cats belonging to one breeding center (n=28) and two cat shelters (A and B, n=25 each). In the catteries, a follow-up analysis for a period of up to 2 months was also performed to determine the parasite shedding pattern in feces and the incidence of infection. Fecal samples were analyzed using in vitro culture and a PCR technique. T. foetus was detected in a total of 38.7% (36/93) of the cats with chronic diarrhea. Parasite infection was similarly detected in family cats and cattery animals (40% versus 38.4%). In the catteries, the parasite was detected in 50%, 44% and 20% of the animals from the breeding center and shelters A and B, respectively. The follow-up analysis showed that 58.3% of infected cats intermittently shed trophozoites in their feces, with an incidence of 23.1%. Investigation of potential risk factors showed that cats ≤1 year old were more likely to be infected than older cats (57.1% versus 27.3%; P<0.05). No significant differences were found when sex and breed factors were studied. These results confirm the importance of FT as a cause of chronic diarrhea in cats and highlight the relevance of close contact conditions for T. foetus transmission.

There is no agreement in the literature as to the time of the onset and progress of the vertebral column ossification. The aim of the present study was to determine the precise sequence of ossification of the neural arches and vertebral centra.Histological and radiographic studies were performed on 27 human foetuses aged from 9 to 21 weeks. It was found that the ossification of vertebrae commences in foetuses aged 10 and 11 weeks. Ossification centres appear first for neuralarches in the cervical and upper thoracic vertebrae and by the end of 11th week they are present in all thoracic and lumbar neural arches. In the vertebral centrain foetus of 10 weeks ossification was found in the lower 7 thoracic and first lumbar vertebrae. By the end of 11th week ossification is present in the lower 4 cervical, all thoracic, all lumbar and 4 sacral vertebral centra. The study indicates that ossification of the neural arches proceeds in the craniocaudal direction,whereas in the vertebral centra it progresses from the lower thoracic vertebrae into both directions. Different shapes of ossification centres were also described.

Twenty bitches were seen in consultation at the Department of Reproduction at ONIRIS (College of Veterinary Medicine, Food Science and Engineering, Loire Atlantique, Nantes, France) between 25 and 50 days of gestation for early sex determination of the canine foetus using ultrasound. The genital tubercle is not visible before 26 days; between 26 and 30 days, it is visible between the pelvic limbs; between 33 and 50 days, the position of the genital tubercle enables sex determination as it migrates caudally in the female and cranially in the male. Good statistical concordance between sexing via ultrasound and sexing at birth has been established (kappa coefficient of 0.8). Macroscopic, microscopic, and histological examinations of the external genital organs were also performed on 10 foetuses at 35 days of gestation; a cartilaginous structure was visualized in the genital apparatus of the male but also in half of the females. Finally, the development of a PCR technique on the SRY gene using formaldehyde-preserved tissues has been described for the first time in this study. It served as a reference for sexing canine foetuses.

Tritrichomonas foetus mutants resistant to metronidazole lack the hydrogenosomal enzymes pyruvate: ferredoxin oxidoreductase and hydrogenase. Hydrogenosomes of these organisms did not oxidize pyruvate or produce ATP in its presence. Elimination of hydrogenosomal metabolism of pyruvate was compensated by an increased rate of glycolysis. The resistant mutants excreted no organic acids and H2 as metabolic end products. Glycolysis of the resistant T. foetus KV1-1MR-100 can be summarized as 1 mol glucose----2 mol ethanol + 2 mol CO2. The parent strain KV1, excreting H2, CO2 and acidic end products, converted about 10% of glucose to ethanol. Both strains produced ethanol from pyruvate through the action of two cytoplasmic enzymes: pyruvate decarboxylase and alcohol dehydrogenase. The specific activity of the former enzyme, catalyzing nonoxidative decarboxylation of pyruvate to acetaldehyde, was nearly seven times higher in the resistant than in the parent strain. Alcohol dehydrogenase reducing acetaldehyde to ethanol was specific to NADPH; it catalyzed the reverse reaction only slowly, and displayed similar activities in both resistant and sensitive trichomonads. Development of anaerobic metronidazole resistance in T. foetus depended on the loss of pyruvate:ferredoxin oxidoreductase as well as on the ability to increase alcoholic fermentation.

The Ca(++)-antagonist nifedipine has been successfully employed in the treatment of non-gravid hypertension, and was found to inhibit uterine contractions in the perimenstrual period, as well as during premature labour in animal models. The use of antihypertensive drugs in pregnancy introduces the possibility of iatrogenic foetal distress. It has been established that nifedipine crosses the placental barrier in the sheep and causes a fall in mean arterial pressure and tachycardia in both the ewe and the foetus. This paper examines the effects of nifedipine on the foetus when administered to the pregnant ewe. Catheters and electrodes were implanted by surgical procedures in 15 ewes and foetal lambs between days 118 and 122 of gestation. The redistribution of foetal blood flow was measured by the radioactive microsphere injection technique. The infusion of nifedipine caused a 9% increase in the combined ventricular output (CVO) from 446 to 509 ml/min/kg in the foetus. Foetal lung blood flow increased from 29 +/- 6 to 69 +/- 14 ml/min/kg while figures for the skeletal muscle flow were 109 +/- 34 and 141 +/- 41.6 ml/min/kg. Heart and brain blood flow, expressed as percentages of CVO showed variations of 4.3 and 5.6 percent, respectively. Blood flow in the gut, placental membranes, skin, kidney and spleen was reduced. The present results show that nifedipine, in addition to its known effects causes a redistribution of the foetal circulation.

There is increasing evidence that the sex of the foetus may alter the maternal metabolic milieu during pregnancy. Following a randomized controlled trial of exercise in overweight and obese pregnant women, we assessed whether the sex of the foetus was associated with changes in maternal metabolism. Data were analysed on 74 randomized participants who completed the trial, including 38 mothers carrying males and 36 mothers carrying females. At 19 weeks of gestation, mothers carrying boys had higher blood glucose concentrations than those carrying girls (5.4 vs 4.9 mmol/l; p = .046). At 36 weeks of gestation, differences were more marked, with blood glucose concentrations 15% higher in mothers carrying females (5.7 vs 5.0 mmol/l; p = .004). In addition, mothers carrying girls had higher concentrations of hs-CRP across pregnancy (5.0 vs 3.6 mg/l; p = .029). Our findings provide further evidence that the sex of the foetus appears to influence maternal metabolism.

A flock of 82 non-pregnant ewes was split into three immunisation groups and given an intranasal dose of either cell culture medium, or a type 1 or a type 2 bovine viral diarrhoea virus (BVDV-1 or BVDV-2). Two months later the flock was reconstituted and after a further three weeks, the ewes were bred to pestivirus negative rams after synchronisation of oestrus using progesterone sponges. Fifty-five ewes were segregated into three challenge groups, each of which comprised ewes from different immunisation groups. At 7 weeks gestation, one challenge group was given an intranasal dose of cell culture medium, whilst the other two were given intranasal doses of either BVDV-1 or BVDV-2, using the same inocula as for the immunisations. Three weeks later, the ewes were killed and their foetuses tested for the presence of BVDV-1 and BVDV-2. The results showed that immunisation of six ewes without subsequent challenge did not lead to infection of any of their 11 foetuses. Challenge with BVDV-1 or BVDV-2 in the absence of immunisation lead to 15 out of 15 or 11 out of 14 foetuses becoming infected, respectively. Immunisation with the homologous virus to that used for challenge resulted in complete protection of 32 foetuses from 15 ewes. Heterologous protection was one way. All 12 foetuses from ewes immunised with BVDV-1 were protected from challenge with BVDV-2, whereas 18 foetuses from ewes immunised with BVDV-2 were all infected after challenge with BVDV-1. This provides evidence that a recent exposure to infection with one pestivirus does not necessarily induce foetal protection against another. The one-way result suggests that factors other than antigenic differences are involved in cross-protection.
A beef producer purchased Angus crossbred cattle that were pregnant with nursing calves. The purchased cattle, their nursing calves, and subsequent born calves were not initially tested for BVDV. Bovine viral diarrhea virus subtype 2a (BVDV2a) was isolated from an aborted bovine fetus, 6.5 months,...
A pastor comments on the recent ruling by the Swedish Department of Health and Social Affairs that the remains of an abortion should be "treated respectfully"--cremated or buried in a cemetery. This decision results from recognition on the part of the government and the medical establishment that a growing segment of public opinion agrees that the fetus is a human being. The new rules mean, though, that a fetus becomes human only upon its death. Logically, an abortion that is respectfully performed ought not to be performed at all. This is the fundamental problem with abortion, and no amount of arbitrary boundary drawing at various levels of supposed capability for survival at the 12th, the 18th, or the 24th week of pregnancy will alter the fact. It is necessary to face the problem with complete intellectual honesty and say that a fetus is a human being no matter what its age, but that voluntary abortion is also a social necessity. Only then can society find another abortion policy, one that recognizes that late abortions are hard to distinguish from births. The Swedish abortion policy must reflect honest facts, rather than etiological legends, preconceived ideas for which arguments must be found afterward.

Europe is experiencing the same conflict over abortion that the US is having. In Germany the unification has resulted in not 1, but 2 abortion laws. Each law apples to the old borders, but a new law is to be formulated by 1992. The most restrictive abortion laws are in Ireland where there is total prohibition. The most permissive laws are in the Netherlands where it is available on demand until the 24th week. France, Belgium, Spain, Italy have all relaxed their laws to some degree; however, there is no common European position on abortion. Eastern European countries have seen abortion banned, to increase the population to survive a war with the West, to having it become the primary form of birth control decades later. In Poland, as well as many other Eastern European countries, abortion is beginning to become illegal again as independence allows the freedom of the citizens to choose their own laws and rights. The development of new drugs, such as RU486 or mifepristone, has also influenced a change in abortion policy. Currently it is legal in France and Great Britain.

An estimated 60 000-70 000 women die annually from complications of unsafe abortion and hundreds of thousands more suffer long-term consequences which include chronic pelvic pain and infertility. The reasons for the continuing high incidence of unwanted pregnancy leading to unsafe abortion include lack of access to, or misuse of and misinformation about, effective contraceptive methods, coerced sex which prohibits women from protecting themselves, and contraceptive failure. Unsafe abortion is closely associated with restrictive legal environments and administrative and policy barriers hampering access to existing services. Vacuum aspiration and medical methods combining mifepristone and a prostaglandin for early abortion are simple and safe. For second trimester abortion, the main choices are repeat doses of prostaglandin with or without prior mifepristone, and dilatation and evacuation by experienced providers. Strategies for preventing unsafe abortion include: upgrading providers' skills; further development of medical methods for pregnancy termination and their introduction into national programmes; improving the quality of contraceptive and abortion services; and improving partner communication.

I argue that it is possible for prospective mothers to wrong prospective fathers by bearing their child; and that lifting paternal liability for child support does not correct the wrong inflicted to fathers. It is therefore sometimes wrong for prospective mothers to bear a child, or so I argue here. I show that my argument for considering the legitimate interests of prospective fathers is not a unique exception to an obvious right to procreate. It is, rather, part of a growing consensus that procreation can be morally problematic and that generally talking of rights in this context might not be warranted. Finally, I argue that giving up a right to procreate does not imply nor suggest giving up on women's absolute right to abort, which I defend.
The Cardinal of Milan and the linguist and writer Umberto Eco maintained a correspondence in the mid-1990s in connection with the Italian magazine ¿Liberal¿. One of the issues discussed was the conflict between belief in the value of human life and existing abortion legislation. Umberto Eco stated that he would do all in his power to dissuade a woman pregnant with his child from having an abortion, regardless of the personal cost to the parents, because the birth of a child is a miracle. He would not, however, feel capable of imposing his ethical position on anyone else. Terrible moments occur in which women have a right to make autonomous decisions concerning their bodies, their feelings, their futures. Those who disagree cite the right to life, a rather vague concept about which even atheists can be enthusiastic. The moment at which a new human being is formed has been brought to the center of Catholic theology, despite its uncertainty; the beginning of a new life may always need to be understood as a process whose end result is the newborn. Only the mother should decide at what moment the process may be interrupted. The cardinal¿s response distinguished between psychic and physical life, on the one hand, and life participating in the life of God on the other. The threshold is the moment of conception, reflecting a continuity of identity. The new being is worthy of respect. Any violation of the affection and care owed to the being can only be experienced as a profound suffering and painful laceration that may never heal. The response of Eco is unknown.

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.
In Latin American countries abortion on demand is legal only in Cuba and must be performed there in hospitals within the 1st 12 weeks of pregnancy. After the 1st trimester, it can be performed only for medical reasons. With regard to the other 18 Latin American countries, abortion is illegal in 2 of them even for saving the life of the pregnant women. In 9 countries therapeutic abortion is permitted only to save the woman's life. It is allowed in 4 countries in the case of severe disease that will be aggravated if the pregnancy continues. In the 3 remaining countries, in addition to medical reasons, it is legal if pregnancy is the consequence of incest or rape. Despite the law, induced abortion is often performed. The complications of illegal abortion are reviewed along with mortality and morbidity and abortions in adolescents. In Colombia in 1974, 58,717 women were hospitalized for complications of abortion. 42,160 women were hospitalized in Chile in 1974 with the same diagnosis. As Colombia and Chile both have family planning programs and effecive contraceptives are easily obtained, the rate could be even higher in those countries without programs or contraceptive availability. From surveys conducted in these 2 countries, it may be concluded that only 1 out of 3 induced abortions is complicated and requires hospitalization. The hospitalization for complications of abortion/1000 women of fertile age in Colombia and Chile suggests that there is an annual average of 15 hospitalized cases/1000 women of fertile age throughout Latin America. Presuming reasonable accuracy for these surveys, the rate of induced abortion in the entire continent can be estimated to be at least 45/1000 women of fertile age. From this, without considering Cuba, a conservative estimate of 3.4 million illegal induced abortions are performed annually in Latin America. It seems that illegal abortions are performed at an even higher rate than that observed in countries where abortion is legal and

I discuss three topics. First, there is a philosophical connecting thread between several recent trends in the abortion discussion, namely, the issue of our animal nature, and physical embodiment. The philosophical name given to the position that you and I are essentially human animals is "animalism." In Section II of this paper, I argue that animalism provides a unifying theme to recent discussions of abortion. In Section III, I discuss what we do not find among recent trends in the abortion discussion, namely "the right to privacy." I suggest some reasons why the right to privacy is conspicuous by its absence. Finally, I address Patrick Lee's claim that the evil of abortion involves "the moral deterioration that the act brings to those who are complicit in it, and to the culture that fosters it."
This study developed an abortion attitude scale and abortion knowledge inventory that may be utilized by health educators, counselors, and researchers for assessing attitudes toward abortion and knowledge about it. (SK)

The technique of amniocentesis, by which an abnormal fetus can be detected in utero, has brought a technological advance in medical science but attendant medical and moral problems. Dr Seller describes those congenital disabilities which can be detected in the fetus before birth, for which the "remedy" is selective abortion. She then discusses the arguments for and against selective abortion, for the issue is not simple, even in the strictly genetic sense of attempting to ensure a population free of congenital abnormality.

Tritrichomonas foetus is a protozoan parasite that has been associated with chronic diarrhea in cats. This study aimed to determine (i) the prevalence of T foetus shedding in cats from three different populations in southern Ontario, and (ii) associations between the presence of T foetus and potential cat management, health and demographic risk factors. A cross-sectional study was conducted involving 140 cats from a cat clinic in Guelph, 46 cats from a humane society in Guelph and 55 cats from two cat shows. Risk factor information was assessed through a questionnaire. The InPouch TF (feline) culture method was used to determine the presence of T foetus in all samples. Polymerase chain reaction was conducted on all samples positive by the InPouch TF, as well as 132 negative samples. The assays were interpreted in series and the prevalence of T foetus shedding and 95% confidence intervals (CI) were estimated at 0.7% (95% CI: 0.0-3.9%; n = 140) from the cat clinic, 0% (95% CI: 0.0-7.7%; n = 46) from the humane society and 23.6% (95% CI: 13.2-37.0%; n = 55) from the cat shows. 'Attendance at cat shows' was the only variable significant in both the univariable and multivariable analyses (P <0.05). No significant association was found between the presence of T foetus and diarrhea at the time of sampling or having a history of diarrhea in the past 6 months. The prevalence of T foetus was highly variable among populations of cats in southern Ontario, with shedding being most common in show cats.
Data on unsafe abortions, defined as those provided by persons lacking the necessary skills in an environment failing to meet medical standards, are scarce given the legal and ethical implications of reporting such procedures. However, the World Health Organization estimates that 20 million unsafe abortions occur each year, 90% of them in developing countries under conditions of illegality. The rate is 8/1000 women of reproductive age in more developed countries compared with 17/1000 in less developed countries; the highest rate (47/1000) exists in Latin America. Worldwide, there are an estimated 70,000 unsafe abortion-related deaths each year; again, the risk of mortality is at least 15 times higher in developing than developed countries. In addition, about 20-30% of unsafe abortions result in reproductive tract infections, many of which produce infertility. Of concern is the increase in unsafe abortion among unmarried adolescents who lack access to fertility control services. Urged is a reframing of the abortion issue on the basis of a commitment to women's reproductive health and well-being.

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

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

Abortion is illegal in Uganda except to save the life of the woman. Nevertheless, the practice is quite common: about 300,000 induced abortions occur annually among Ugandan women aged 15-49 (Singh et al., 2005) and a large proportion of these women require treatment for post-abortion complications. In the male-dominant culture of Uganda, where men control most of the financial resources, men play a critical part in determining whether women receive a safe abortion, or appropriate treatment if they experience abortion complications. This study examines men's roles in determining women's access to a safer abortion and post-abortion care. It draws on in-depth interviews carried out in 2003 with 61 women aged 18-60 and 21 men aged 20-50 from Kampala and Mbarara, Uganda. Respondents' descriptions of men's involvement in women's abortion care agreed that men's stated attitudes about abortion often prevented women from involving them in either the abortion or post-abortion care. Most men believe that if a woman is having an abortion, it must be because she is pregnant with another man's child, although this does not correspond with women's reasons for having an abortion--a critical disjuncture revealed by the data between men's perceptions of, and women's realities regarding, reasons for seeking an abortion. If the woman does experience post-abortion complications, the prevailing attitude among men in the sample was that they cannot support a woman in such a situation seeking care because if it had been his child, she would not have had a covert abortion. Since money is critical to accessing appropriate care, without men's support, women seeking an abortion may not be able to access safer abortion options and if they experience complications, they may delay care-seeking or may not obtain care at all. Barriers to involving men in abortion decision-making endanger women's health and possibly their lives.

The primary objective of this study was to identify herd management and cow characteristics that are associated with abortion in cow-calf herds in Western Canada. Reproductive events were closely monitored in 29,713 cows in 203 herds from the beginning of the breeding season in 2001 through the calving season in 2002. Herd management and cow-level risk factors such as age, body condition score, and previous reproductive history were measured through a series of herd visits by project personnel and detailed individual animal records maintained by the herd owner. Pregnancy status was assessed in fall of 2001 by the herd veterinarian. Cows most likely to abort were replacement heifers, cows that were more than 10 years of age, cows with a body condition score of less than or equal to or 5 of 9 at pregnancy testing, or with twin pregnancies. Cows vaccinated for bovine viral diarrhea virus and infectious bovine rhinotracheitis and bred on community pastures were less likely to abort than cows from community pastures that were not vaccinated. Cows bred on community pastures that were not vaccinated were also more likely to abort than cows that were not on community pastures regardless of vaccination status. Adverse calving-associated events such as severe dystocia, problems such as uterine prolapse or retained placentas, abortion or calf death within 1 hour of birth were also associated with an increased risk of abortion the subsequent calving season after accounting for all other factors.
The sort of ethical theory derived from Aristotle, variously described as virtue ethics, virtue-based ethics, or neo-Aristotelianism, is becoming better known, and is now quite widely recognized as at least a possible rival to deontological and utilitarian theories. With recognition has come criticism, of varying quality. In this article I shall discuss nine separate criticisms that I have frequently encountered, most of which seem to me to betray an inadequate grasp either of the structure of virtue theory or of what would be involved in thinking about a real moral issue in its terms. In the first half I aim particularly to secure an understanding that will reveal that many of these criticisms are simply misplaced, and to articulate what I take to be the major criticism of virtue theory. I reject this criticism, but do not claim that it is necessarily misplaced. In the second half I aim to deepen that understanding and highlight the issues raised by the criticisms by illustrating what the theory looks like when it is applied to a particular issue, in this case, abortion.

(IMC clone 2 (cl2)) was performed for several genetic regions including the ITS1-5.8S rDNA-ITS2 region, the cysteine protease (CP)-1, CP-2 and CP-4 to CP-9 genes, and the cytosolic malate dehydrogenase 1 gene. In addition to comparison of the variable-length DNA repeats in the isolate clone with those in T. foetus (Inui cl2) and the T. mobilensis (U.S.A.: M776 cl2) reference strains, this analysis showed that the Tritrichomonas sp. (IMC cl2) was T. foetus (cattle/swine genotype). Injection of T. foetus (IMC cl2) directly into the livers of CBA mice resulted in liver abscess formation on Day 7. Moreover, inoculation via orogastric intubation caused infection in the cecum on Day 5 in CBA mice co-infected with Entamoeba histolytica (HM-1: IMSS cl6). T. foetus (IMC cl2) was able to grow in YI-S medium for over 20 days, even at 5°C. These results indicate that the T. foetus isolate is able to survive in the feces and edible organ meat of the definitive host for a prolonged period of time, and it is possible that the parasite could infect humans.

Low birth weight (LBW) baby predisposes to long term renal disease, adult hypertension and related cardiovascular disease. This could be due to reduced nephron number in early life. From different studies, it is becoming increasingly clear that nephron number, indirectly reflected in renal volume may be related with normal or retarded foetal growth. This prospective study was undertaken in the department of Obstetric and Gynae in Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh. One hundred pregnant women were included in this study and divided into two groups (IUGR and normally growing foetuses). Forty one foetuses weighted less than 2.5kg and fifty nine foetuses weighed 2.5kg or more. Kidney dimensions and estimated feotal weight were measured by USG by the same ultrasonologist. There were no significant difference between two groups regarding age, height, weight, and parity. The subjects with intrauterine growth retardation had smaller head circumference, abdominal circumferences, biparietal diameters, femur length, estimated foetal weight and lower amniotic fluid indices than did the subjects with non-intrauterine growth retardation (IUGR). All biometric data shows significant deference except head circumference (HC). Intrauterine growth retardation (IUGR) foetus had significantly lower kidney volume than normally growing foetuses.

A German abortion isolate of EHV-1 (strain M8) was grown in equine dermal (ED) cells at a low multiplicity of infection in presence of 5-bromo-2-deoxy uridine. The resulting stock was dialysed, titrated and cloned by terminal dilution in ED cells grown in 96-well microtitration plates. Of 192 clones each originating from a single focus, clone 147 (C147) was found to be restricted for growth at and above temperatures of 38.5 degrees C. It was also restricted for growth at 37 degrees C in rabbit kidney (RK-13) cells which are widely used for the isolation and titration of EHV-1; hence clone 147 was EHV-4-like. Clone 147 showed a remarkable efficacy as a vaccine in protecting conventional pregnant Welsh Mountain pony mares against abortions due to EHV-1. A single intranasal (IN) vaccination protected five out of six (83.3%), and four out of five (80%) of mares upon challenge 4 and 5-6 months, respectively, after the immunisation, whereas all six unvaccinated mares aborted between 9 and 19 days after IN EHV-1 challenge. With the exception of the day 9 abortion, foetuses of the remaining five mares were EHV-1 infected. Placenta from the early aborting mare was, however, EHV-1 positive. Both groups of vaccinated mares were also significantly protected against clinical reaction (notably pyrexia), nasal shedding and viraemia following challenge infection.
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.
On October 24, the Sejm (Poland's lower house of parliament) voted 228 to 195 (with 16 abstentions) to amend Poland's March 1993 ban on abortions. The amendment legalizes abortion until the 12th week of pregnancy for women who face financial hardship or difficult personal circumstances. Client counseling by a doctor who will not perform the abortion and a 3-day wait are required. Abortions will be permitted in licensed private clinics, as well as in public hospitals. Anyone performing an illegal abortion can receive 2 years' imprisonment. The government will subsidize contraceptive pills, and a sex education curriculum will be developed for schools. Abortion had been legal and widely available under communist rule; however, a Catholic-aligned government limited abortion to cases where a woman's life or health was endangered, where the pregnancy resulted from rape or incest, or where the fetus had a severe anomaly. The Catholic Church opposed the new measure, and the Senat (Poland's upper house), on October 3, had voted 40 to 52 (with 2 abstentions) against the amendment. Although the Sejm had previously voted 208 to 61 (with 15 abstentions) in favor of the amendment, 120 of those opposed to the measure, primarily members of the Polish Peasants Party (part of Poland's ruling coalition), had walked out in protest just before an August tally. The Democratic Left Alliance, the other coalition partner, supports the amendment. The most recent vote in the Sejm overturns the Senat veto; however, before the law can go into effect in 1997, it must be signed by President Aleksandr Kwasniewski (a supporter) after a review by Poland's conservative constitutional tribunal.
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.

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

The attitudes toward abortion of students and faculty in 3 health related fields--nursing, medicine, and social work--are examined and compared with the views of the population at large. The relation of religious affiliation to attitude toward abortion is also examined. The data was obtained via questionnaire in 47 nursing, 11 medical, and 15 social work schools in the fall and winter of 1971. 7 attitudinal items provided the focus of attention. 5 dealt with conditions under which an abortion should be performed; 2 dealt with the willingness of the respondent to help a client get an abortion. Nursing students and faculty had the most conservative attitude, followed by medical personnel and social workers. The nursing faculty's opinions were most like those of the general public; the medical and social work students and faculty generally mirrored respondents with some college education. Catholic health professionals were even less in favor of abortion than Catholics at large, even those with only a grade-school education. Catholic students, however, were more favorably disposed than Catholic faculty, indicating a more liberal trend in the Catholic Church.
This article talks about the position on abortion held by Catholics for a Free Choice (CFFC). The discussion is based on an electronic mail message sent in response to a question on a Church reform listserve discussion group. CFCC believes that abortion is a serious matter that requires reflection, including dialogue with partners and trusted advisors. In a Catholic theological context and in the realm of morality, respect for women's right to abortion should be based on these facts: 1) there is no firm position within the Catholic Church on when the fetus becomes a person; 2) the principle of probabilism in Roman Catholicism holds that where the Church cannot speak definitively on a matter of fact, the consciences of individual Catholics must be primary and respected; and 3) the absolute prohibition on abortion by the Church is not infallible. For CFFC, a central value in this complex matter is the recognition that women are competent, capable moral agents who must be recognized as having the moral and legal right to make the decision about whether or not to have an abortion with minimal state intervention.

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

A cross-sectional study examined the occurrence of Tritrichomonas foetus, and other intestinal parasites, in feral and shelter cats in Prince Edward Island (PEI). Fecal samples were collected from 100 feral cats, 100 cats from the PEI Humane Society, and 5 cats from a private residence. The occurrence of T. foetus, based on fecal culture, was 0% in feral and shelter cats. A single positive sample was obtained from an owned Abyssinian cat that was imported to PEI. Intestinal parasites were identified via fecal flotation in 76% of feral cats and 39% of cats from the humane society. Feral cats had a higher incidence of Toxocara cati than cats from the humane society (P < 0.001), conversely, shelter cats had a higher incidence of Cystoisospora spp. (P < 0.001). These results suggest that while T. foetus is not of importance in feral and shelter cats in PEI, imported cats could serve as reservoirs. PMID:26933262

As medical abortion becomes more widely used and available in Greece, several issues are emerging and require clarification. Health care providers often face a dilemma when dealing with an adolescent requesting abortion. Parents' consent is mandatory before delivering any kind of treatment to minors. However, as it appears in the case presented here, the circumstances are not always straightforward. A critical review of the Greek legal framework in relation to the current social context is attempted through an interesting case aiming to elicit potential defects of the law that should be addressed by the legislator.

The economic impact of abortions in ruminant breeders is one of the biggest problems in livestock. Of the infectious agents, viruses, especially herpesviruses and pestiviruses, are the most important causative agents of abortion in ruminants. In the present study, the role of herpesviruses (bovine herpesvirus-1 (BoHV-1), bovine herpesvirus-4 (BoHV-4)) and pestiviruses (bovine viral diarrhea virus (BVDV), border disease virus (BDV)) was investigated in cases of ruminant abortion between 2007 and 2015 in western Turkey. Out of 81 aborted fetal samples (60 calves, 19 lambs, and 2 kids), 42 were positive, which included 31 calves, 9 lambs, and 2 goats; 39 aborted fetal samples were negative for the pestivirus antigen ELISA. BoHV-1 antigen ELISA was positive in 3 cases which included 2 calves and 1 lamb; the remainder 78 cases were negative. Pestivirus and BoHV-1 were positive in 51.85 and 3.70 %, respectively, of the samples. According to PCR analysis, BoHV-4 was not encountered in any of the tested samples. In one of the calf fetus samples, both BVDV and BoHV-1 were positive; in one of the lamb fetus samples, BoHV-1 was positive. There was a much higher level of pestivirus antigen than the other viral agents evaluated in the study (p < 0.0001). The results of this study indicate that pestiviruses are a common viral cause of ruminant abortions in the examined area.

Neosporosis, a disease caused by the obligate intracellular protozoan Neospora caninum, produces abortions in cattle. The severe economic losses in cattle industry justify the need to develop control measures for preventing bovine abortion. Apicomplexan parasitic resistance is associated with T helper 1 immune response mediated by CD4 cytotoxic T lymphocytes, the production of interferon-gamma, interleukin-12, tumor necrosis factor and immunoglobulin G2. The reduction of vertical transmission in subsequent pregnancies and the low levels of abortion repetition suggests the existence of protective immune mechanisms. Inoculation with live tachyzoites before mating protects against infection and abortion. Antecedents of the development of live vaccines against other protozoa stimulate research to develop a live vaccine against N. caninum. On the other hand, an inactivated vaccine with low efficacy against neosporosis is useful in the prevention of abortion in farms with epizootic disease. A neosporosis vaccine should avoid abortion, transplacental transmission and infection persistence. In the present work, advances in vaccine development including lysate of tachyzoites, live parasites, recombinant antigens and vaccine vectors are reviewed.

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

Neospora caninum is a protozoan parasite with a wide host range but with a preference for cattle and dogs. Since the description of N. caninum as a new genus and species in 1988, bovine neosporosis has become a disease of international concern as it is among the main causes of abortion in cattle. At present there is no effective treatment or vaccine. This review focuses on the epidemiology of the disease and on prospects for its control in cattle. Finally, based on the implications of clinical findings reported to date, a set of recommendations is provided for veterinarians and cattle farmers.

Two trials were carried out to assess the diagnostic sensitivity and practicability of preputial scraping as a method of collecting preputial material from bulls infected with Tritrichomonas foetus. In the 1st trial, preputial material was collected by simultaneous scraping and aspiration from 3 infected and 1 uninfected bull 10 times over a 5-week period. In the 2nd trial, samples from 5 infected bulls were collected by both sheath washing and scraping on 6 occasions, while 8 uninfected animals were sampled 3 times. Samples were cultured using a modified Trichomonas culture medium (Oxoid). In the first trial, 29 of 30 samples from infected bulls were found to be positive. In the second trial, 83 % of samples collected by both methods tested positive. In neither trial were any samples from the control bulls found to be positive. Scraping was found to be quick and safe, and offered advantages over preputial washing in that urine contamination was easily avoided, samples were smaller and more concentrated and contamination was reduced. It may, however, be subject to greater operator variability than sheath washing. It is concluded that preputial scraping is as effective as washing and represents a suitable alternative for the collection of material for direct examination and culture of Tritrichomonas foetus.
The author examines aspects of abortion in Italy through the examination of data on 1,400 women under 25 years of age who were hospitalized for delivery or abortion in a Bologna hospital in 1976-1977. In particular, the author analyzes the data by characteristics including age of mother, marital status, place of residence, and profession or occupation in order to examine the extent to which induced abortions are included in the totals reported as spontaneous abortions.

In this commentary, the impact of the introduction of manual vacuum aspiration (MVA) for incomplete abortion patients and for early uterine evacuation is discussed for the University Teaching Hospital in Lusaka, Zambia. This 3-year training and service delivery program was begun in 1988 after it was clear that 15% of maternal deaths were due to illegally induced abortion. The prior procedure of dilation and curettage (D and C) required use of the main operating room and general anesthesia, which resulted in severe congestion and treatment delays. As a result of the new MVA procedure, congestion has decreased substantially, treatment is safer and more timely, and the staff's ability to provide abortions has increased. Family planning counseling is provided to postabortion patients in a more thorough fashion, and the savings in time has improved the quality of patient-staff interactions. Specifically, the patient flow has improved from a 12-hour wait to a 4-6 hour wait and rarely requires overnight hospitalization. The demand for the main operating room had decreased which frees space, time, and commodities for other gynecological treatment. The shorter procedure and release time means a minimal loss of earnings and productivity, and allows for greater privacy in explaining absences to families, schools, or employers. The improved quality of are is reflected in the figures for number treated, i.e., in 1989, 74% were treated with MVA for incomplete abortion 12 weeks and pregnancy termination 8 weeks compared with 26% treated with D and C. In 1990, the figures were 86% with MVA and 14% with D and C. The likelihood of complications from hemorrhage and sepsis have also been reduced. The MVA procedure is also less traumatic for the patient. The increased access to safe legal abortion services is reflected in the ratio of induced to incomplete abortions between 1988-1990 (1:25 to 1:5). Family planning counseling is provided by a full-time counselor who counsels preabortion

Unsafe abortions and their complications are a major cause of maternal mortality. Hospital based studies from most African countries confirm that up to 50% of maternal deaths are due to abortion. This paper reviews problem of induced abortion in sub-Saharan Africa. Issues of prevalence and prevention are addressed while acknowledging the need to review the legal regimes operating in these countries.

When New York State's abortion laws were liberalized in 1970, there was a sharp rise in the number of clinic patients who requested abortions. Because social workers at Mount Sinai Medical Center believed that abortion still is an emotional risk for many women, a study was conducted to determine which patients needed intensive counseling.

Thirty-six bovine viral disease viruses (BVDVs) were identified in bovine feces (n=16), brains (n=2), and aborted fetuses (n=18) in Korea. To reveal the genetic diversity and characteristics of these Korean strains, the sequences of their 5'-untranslated regions (5'-UTRs) were determined and then compared with published reference sequences. Neighbor-joining phylogenetic analysis revealed that most of the Korean viruses were of the BVDV subtypes 1a (n=17) or 2a (n=17). The remaining strains were of subtypes 1b (n=1) and 1n (n=1). This analysis indicates that the 1a and 2a BVDV subtypes are predominant and widespread in Korea. In addition, the prevalence of BVDV-2 was markedly higher in aborted fetuses than in other samples and was more often associated with reproductive problems and significant mortality in cattle.
This paper deals with the main arguments in Europe against selective abortion after prenatal diagnoses and against using prenatal diagnoses as a whole from an ethical point of view. The different experiences from the Eastern and the Western parts of Germany are used as examples. The paper suggests that using ethics could promote multicultural experiences and different strategies of decision-making.
In 'After-birth abortion: why should the baby live?', Giubilini and Minerva argue that infanticide should be permitted for the same reasons as abortion. In particular, they argue that infanticide should be permitted even for reasons that do not primarily serve the interests (or would-be best interests) of the newborn. They claim that abortion is permissible for reasons that do not primarily serve the interests (or would-be interests) of the fetus because fetuses lack a right to life. They argue that newborns also lack a right to life, and they conclude that therefore, the same reasons that justify abortion can justify infanticide. This conclusion does not follow. The lack of a right to life is not decisive. Furthermore, the justificatory power of a given reason is a function of moral context. Generalisations about reasons across dissimilar moral contexts are invalid. However, a similar conclusion does follow-that fetus-killing and newborn-killing are morally identical in identical moral contexts-but this conclusion is trivial, since fetuses and newborns are never in identical moral contexts.

Neospora caninum infection is a leading cause of abortion in cattle worldwide. The pathogenesis of bovine neosporosis, particularly during the second term of gestation when most abortions occur in naturally infected dams, is poorly understood. In the present study foetal death was observed in 3 of 6 experimentally infected dams at 110 days of gestation after 6 weeks of experimental period. All experimental heifers were febrile between 3 and 5 days post infection (dpi). Inoculated dams seroconverted by 3-4 weeks post-infection with higher mean antibody titres in aborting dams compared to non-aborting heifers, although not significantly (p > 0.05). Neospora caninum DNA was detected in all infected foetuses and placentas, and three infected foetuses also had N. caninum antibodies. The parasite burden was higher in the brain of dead/aborted foetuses than in live foetuses. Interestingly, high IFN-γ production was detected in foetal fluids of a dead foetus found upon euthanasia of its dam, while no IFN-γ was observed in amniotic, allantoic and/or foetal fluids in the three infected foetuses that were alive upon maternal euthanasia. The present study confirms that the infection of dams on gestation day 110 with 10(7) tachyzoites of the Nc-Spain7 isolate causes abortion. The fact that some infected dams aborted and some did not is relevant to the understanding of N. caninum pathogenesis of abortion in naturally infected cows.

Comparisons of the efficacy of different regimens of medical abortion are difficult because of the widely varying protocols (even for testing identical regimens), divergent definitions of success and failure, and lack of a standard method of analysis. In this article we review the current efficacy literature on medical abortion, highlighting some of the most important differences in the way that efficacy has been analyzed. We then propose a standard conceptual approach and the accompanying statistical methods for analyzing clinical trials of medical abortion and to explain how clinical investigators can implement this approach. Our review reveals that research on the efficacy of medical abortion has closely followed the conceptual model used for analysis of surgical abortion. The problem, however, is that, whereas surgical abortion is a discrete event occurring in the space of a few minutes or less, medical abortion is a process typically lasting from several days to several weeks. In this process, two events may occur that are not possible with surgical abortion. First, the woman can opt out of the process before a fair determination of efficacy can be made. Second, the process of medical abortion allows time for surgical interventions that may be convenient for the clinician but not strictly necessary from a medical perspective. Another difference from surgical abortions is that, for medical abortions, different medical abortion protocols specify different waiting periods, giving the drugs less time to work in some studies than in others before a determination of efficacy is made. We argue that, when analyzing efficacy of medical abortion, researchers should abandon their close reliance on the analogy to surgical abortion. In fact, medical abortion is more appropriately analyzed by life table procedures developed for the study of another fertility regulation technology; contraception. As with medical abortion, a woman initiating use of a contraceptive method can

Neospora caninum causes abortions in cattle worldwide. The Neospora-cycle of life is heteroxenous. Dogs (Canis familiaris) and coyotes (Canis latrans) are the definitive hosts known at present. Although, transplacental infection is an efficiently mode of transmission in cattle; there are also experimental and field data that prove horizontal transmission. Several techniques are available for diagnosis since neosporosis is recognized as a disease that causes economic losses in cattle. The mechanisms that produce the abortion are not completely understood. The immunomodulation observed during the pregnancy, is associated with a susceptible period where Neospora-abortion can occur. Resistance to the parasite is dependent on T helper cell 1 cytokine responses. This has important repercussions for pregnant female bovine because strong T helper cell 1 cytokine responses are incompatible with successful pregnancy. However, it was demonstrated that chronically infected cows develop immune mechanisms against the abortion caused by a second Neospora-exposure. The comprehension of those mechanisms is needed for the formulation of Neospora-vaccines that prevent bovine neosporosis. General concepts about neosporosis with emphasis in the immune response and perspectives for vaccination are mentioned in the present review.

Certain clinical isolates of Tritrichomonas foetus infect the urogenital tract of cattle while others infect the gastrointestinal tract of cats. Previous studies have identified subtle genetic differences between these isolates with the term "genotype" adopted to reflect host origin. The aim of this work was to seek evidence of host-specific adaptation and to clarify the relationship between T. foetus genotypes. To do this we characterised the proteomes of both genotypes using two-dimensional gel electrophoresis (2DE) coupled with LC-MS/MS. Our comparative analysis of the data revealed that both genotypes exhibited largely similar proteoform profiles; however differentiation was possible with 24 spots identified as having a four-fold or greater change. Deeper analysis using 2DE zymography and protease-specific fluorogenic substrates revealed marked differences in cysteine protease (CP) expression profiles between the two genotypes. These variances in CP activities could also account for the pathogenic and histopathological differences previously observed between T. foetus genotypes in cross-infection studies. Our findings highlight the importance of CPs as major determinants of parasite virulence and provide a foundation for future host-parasite interaction studies, with direct implications for the development of vaccines or drugs targeting T. foetus.
In Sweden abortion has been free and on demand since 1975. The philosophy behind this law is that the pregnant women is the best judge of whether she should have an abortion. Any attempt to change the legal status of abortion should be strongly fought. Criminalizing abortion has never amounted to any good in any country that has tried it. A critical aspect of abortion is that it must be prevented with effective sexual education and free access to contraception. This is the best way to avoid unwanted pregnancies and thus abortion. Still even in Sweden 25% of all pregnancies end in abortion. Planned parenthood is essential in a country with a high standard of living in order to maintain an adequate level of births. Many countries with high standards of living have very low births rates because they do not offer parental leave, short working hours, or day care.

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.

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.

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

A 10-week-old female Ocicat was presented at a primary care feline veterinary practice for failure to thrive and diarrhoea. Numerous trophozoites, atypical for Giardia sp., were detected on a direct faecal examination, in addition to Giardia cysts. Although the failure to thrive and diarrhoea resolved following treatment for giardiasis, further diagnostic tests performed on faecal specimens from the kitten and 15 other Ocicats from the same cattery, including culture of trophozoites in In Pouch medium, PCR testing and molecular sequencing of PCR amplicons, confirmed infection with Tritrichomonas cf. foetus. This is the first report in Australia of feline trichomoniasis, which appears to be an emerging infectious disease of cats. Pertinent information regarding the clinical features, diagnosis, therapy, and potential source of feline trichomoniasis within Australia are discussed.

The morphological and histological examinations of the deep gland of the third eyelid were carried out on pig foetuses coming from the 35th, 50th, 63rd, 94th and 112th day of gestation. The morphological examinations were conducted using the method of macroscopic preparation with a forehead magnifying glass and binocular (magnification 1.5-5.0x). In order to make anatomical elements more visible, 60-80% absolute alcohol and 0.5-4% acetic acid solution were used for the examinations. For the histological examinations, the whole eyeball with developing accessory organs was collected from the pig foetuses on the 35th day of gestation. On the 50th, 63rd, 94th and 112th day of gestation only the deep gland of the third eyelid was collected. Staining with haematoxylin-eosin and Azan method was performed. It was found during the examinations that the process of the formation of the deep gland of the third eyelid starts on the 35th day of gestation. On the 50th day of gestation, the gland cells are evenly distributed in the connective tissue stroma. On the 63rd day of gestation, the connective tissue divides the gland parenchyma into indistinct lobes composed of 6-15 lobules. On the 94th day of gestation, the gland lobes become visible; the efferent ducts are situated in the central part of the lobe. On the 112th day of gestation, the lobes are composed of a high number of lobules composed of two kinds of excretory ducts. The first type of the excretory ducts is lined with the simple cuboid epithelium whose nuclei are situated at the base of the cell. The other type of the excretory ducts is lined with the simple cuboid epithelium whose nuclei are round and arranged less or more peripherally.
Because the primary responsibility for the care and raising of children still falls on women, they should be able to decide freely whether or not to have children. Although many women who do not initially desire their pregnancies turn out to be adequate mothers, studies have shown that unwanted children suffer disproportionately from a variety of emotional and behavioral disorders. Studies have also found that large numbers of women seeking abortions failed to use any contraception while others used less effective methods, sometimes because of lack of knowledge. Even the most reliable contraceptive methods are liable to occasional failures. According to some authors, undesired pregnancy many reflect a struggle of adolescents with authoritarian parents, the search of a lonely person for something to love or possess, a proof of femininity, an expression of conflict with the partner or an attempt to force a marriage, or ambivalence among middle-aged women at the prospect of becoming more independent when their children enter school. Women may obtain abortions at accredited hospitals in the Province of Quebec upon decision of a committee of 3 physicians that continuation of the pregnancy would result in danger to the life or health of the patient. In 1970 some 100-150,000 illegal abortions occurred, resulting in hospitalization of 20,000 women for complications. In 1972, 4 French-speaking hospitals performed 136 of the 2919 therapeutic abortions sought in the Province of Quebec. In recent years the number has increased. Reasons for obtaining an abortion are usually social or economic: poor relationship with the father, sufficient number of children already born, age of the preceding infant, economic difficulties, mother's age, or effect of pregnancy on work. Many adolescents refuse to tell their parents of their pregnancy for fear of their reaction, but others enjoy considerable parental support. A study of about 5000 French speaking adolescents conducted in 1977

Bovine herpesvirus 4 (BoHV-4) has been isolated from cattle with respiratory infections, vulvovaginitis, mastitis, abortions, endometritis and from apparently healthy animals throughout the world. Although it has not yet been established as causal agent of a specific disease entity, it is primarily associated with reproductive disorders of cattle. This virus can infect a wide range of species, either in vivo or in vitro. Two groups of prototype strains were originated from the first isolates: the DN599-type strains (American group) and the Movar-type strains (European group). In Argentina, BoHV-4 was isolated and characterized in 2007 from vaginal discharge samples taken from cows that had aborted. So far, more than 40 isolates, mainly associated with aborting bovine females have been registered in our country.

Abortion is illegal in Rwanda except when necessary to protect a woman's physical health or to save her life. Many women in Rwanda obtain unsafe abortions, and some experience health complications as a result. To estimate the incidence of induced abortion, we conducted a national sample survey of health facilities that provide postabortion care and a purposive sample survey of key informants knowledgeable about abortion conditions. We found that more than 16,700 women received care for complications resulting from induced abortion in Rwanda in 2009, or 7 per 1,000 women aged 15-44. Approximately 40 percent of abortions are estimated to lead to complications requiring treatment, but about a third of those who experienced a complication did not obtain treatment. Nationally, the estimated induced abortion rate is 25 abortions per 1,000 women aged 15-44, or approximately 60,000 abortions annually. An urgent need exists in Rwanda to address unmet need for contraception, to strengthen family planning services, to broaden access to legal abortion, and to improve postabortion care.

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.

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.

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.

In practice the Bangladesh law, allowing abortion only to save the life of the mother, is essentially obsolete. The government has recognized the role of abortion in curing rapid population growth, and it is believed that the attitude towards abortion in Bangladesh is at least not unfavorable. The attempt was made to determine whether this belief is corroborated by the available facts. Data from the Bangladesh Fertility Survey provides a unique framework for discussion of current attitude towards and prevalence of abortion in Bangladesh. The Bangladesh Fertility Survey (BFS) was conducted on a nationally representative sample of 6513 ever-married women under age 50. An overwhelming majority of Bangladeshi women (over 88%) approved of abortion if the woman had conceived as a result of rape and premarital sex. Danger to mother's life (53% approving) was a more acceptable basis for abortion than danger of a malformed child (30%). Abortion on economic grounds was acceptable to only 17% of women. Urban women held more liberal views on abortion than rural residents. Educated couples were found to be more approving of abortion than the less educated. Women with parity 4 or more viewed abortion more favorably than those with lower parity. This was more pronounced among women under the age of 30. The most conservative approval of abortion was expressed by the older women who had a parity of less than 4. Women with the most liberal views on abortion were also contracepting and relying on efficient contraceptive methods. Wider support for abortion was expressed by currently married, fecund, nonpregnant women who were currently using contraception, and this support was more pronounced among women aged 30 and older.

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. This report gives an overview of the gap cleaning procedure and the achieved performance.
The Soviet legacy of widespread reliance on induced abortion is of critical importance to reproductive trends and policies in post-Soviet nations, especially as they strive to substitute contraception for abortion. Using data from two Demographic and Health Surveys conducted in 1995 and 1999, this study analyzes and compares trends in abortion and contraception, women's attitudes toward abortion, and their perceptions of problems associated with abortion and contraception in Kazakhstan. Despite an overall decline in abortion and an increase in contraceptive use since Kazakhstan's independence in 1991, abortion has remained a prominent part of the country's reproductive culture and practices. This study shows how abortion-related views reflect the long-standing ethnocultural differences between the indigenous Kazakhs and Kazakhstan's residents of European roots, as the latter continue to have significantly higher levels of abortion. The study, however, also reveals the internal diversity among Kazakhs with respect to abortion experiences and views, stemming from decades of the Soviet sociocultural influence in Kazakhstan. In addition, the analysis points to some generational differences in views concerning abortion and contraception. Finally, the study demonstrates parallels in attitudes toward abortion and toward contraception, thereby questioning straightforward assumptions about the replacement of abortion with contraception.
Reproductive governance operates through calculating demographic statistics that offer selective truths about reproductive practices, bodies, and subjectivities. Post-abortion care, a global reproductive health intervention, represents a transnational reproductive regime that establishes motherhood as women's primary legitimate reproductive status. Drawing on ethnographic fieldwork conducted in Senegal between 2010 and 2011, I illustrate how post-abortion care accomplishes reproductive governance in a context where abortion is prohibited altogether and the US is the primary bilateral donor of population aid. Reproductive governance unfolds in hospital gynecological wards and the national health information system through the mobilization and interpretation of post-abortion care data. Although health workers search women's bodies and behavior for signs of illegal abortion, they minimize police intervention in the hospital by classifying most post-abortion care cases as miscarriage. Health authorities deploy this account of post-abortion care to align the intervention with national and global maternal health policies that valorize motherhood. Although post-abortion care offers life-saving care to women with complications of illegal abortion, it institutionalizes abortion stigma by scrutinizing women's bodies and masking induced abortion within and beyond the hospital. Post-abortion care reinforces reproductive inequities by withholding safe, affordable obstetric care from women until after they have resorted to unsafe abortion.

In an attempt to discover any pattern to prefire events, abort prefire kicker data from 2007 to the present day have been recorded. With the 2014 operations concluding, this comprises 8 years of prefire data. Any activities that the Pulsed Power Group did to decrease prefire occurrences were recorded as well, but some information may be missing. The following information is a compilation of the research to date.

Knowledge of the causes of canine or feline pregnancy loss is limited and the success rate for making a definitive diagnosis is disappointingly low. Although these facts are discouraging, there are some things that can be done to improve success rates. This paper will address limitations and explore ways for improvement. For abortions caused by microbial infections, there are many reasons why it may not possible to identify the agents. "Non-infectious" causes are much more difficult to diagnose, and their relative importance is unknown. These include endocrine failure, underlying endometrial disease, genetic abnormalities, nutritional deficiencies, and toxicosis from drugs or environmental sources. Genetic abnormalities are a major cause of human pregnancy loss, yet we have little specific information about genetic diseases leading to abortion in animals. This paper addresses ways clinicians and diagnosticians can work together to improve diagnostic success. Necropsy techniques for fetal and placental examination and sampling are briefly reviewed. It is hoped that this series of papers will stimulate discussion on the causes and pathogenesis of pregnancy failure, and focus attention on areas where abortion diagnostics can be improved.

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

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.

Various arguments against abortion are discussed. Lack of consensus concerning the moment of personhood leaves the question in the realm of value judgments which could, in the future, lead to discrimination. A woman has the right to protect her body against a conception; once conception occurs, the fetus also possesses rights. Legal abortion has been shown by various studies to be more risky than childbirth for the mother: 1) studies showing higher mortality rates for legal abortion, 2) studies showing increased risk of future pregnancy-related and other health disorders, and 3) studies indicating that illegal abortion rises with a rise in legal abortions. The social problems which are aggravated by unwanted pregnancies should be solved instead of eliminating the unwanted child. Legalized abortion does not even solve the problem of population control.
This document reports on and summarizes a paper written by Dr. Aurora Perez. The paper, entitled "The Ambiguities and Ambivalence on Abortion Issues in the Philippines," has tackled abortion from a different perspective, treating it as an issue of public health and human rights. It is a public health issue because the prevalence of abortion is a negative reflection of women's access to effective contraception. It is a human rights issue in the context of sexual violence, and Perez has urged a policy that allows therapeutic abortion as a human right of raped women. She also emphasized that maternal death was high in the Philippines because Filipino women were seeking abortion services under unsafe conditions. Perez cited a study, conducted in 1985-86, which showed that 24% of maternal deaths were due to induced abortions.
In Sri Lanka, women do not have access to legal abortion except under life-saving circumstances. Clandestine abortion services are, however, available and quite accessible. 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. Much broader legal and policy reform will be required.
Von Baross, J
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.
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.
This article reports the results of a survey, by mailed questionnaire, of the attitudes among a sample of the Danish population towards abortion for social and genetic reasons. Of 1080 questionnaires sent to a random sample of persons between 18 and 45 years, 731 (68%) were completed and returned. A great majority of the respondents were liberal towards early abortion both for social reasons and in case of minor disease. In contrast, there was controversy about late abortions for social reasons and in the case of Down syndrome. Further there was strong reluctance to accept late abortion in case of minor disease. An analysis of the response patterns showed that most of the respondents had gradualist views on abortion, i.e. they would allow all early abortions, but only abortions for some reasons later in pregnancy. It was also found that the number who would find an early abortion acceptable in general was much higher than the number who would accept it in their own case. These findings suggest that a great part of the resistance towards abortion does not rest on a concern for the rights and interests for the fetus. Instead it may be explained on a view according to which fetal life is ascribed intrinsic moral value.
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.

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.
In the 1984 election, Ronald Reagan, the Republican presidential incumbent and an opponent of legal abortion, defeated Walter Mondale, a prochoice Democrat, by a wide margin. Despite Reagan's sweep of 49 states, however, conservatives lost a little ground in the Senate, where four of the seven new senators elected take a prochoice position on abortion. On the other hand, antiabortion forces registered some gains in the House of Representatives. The voting groups were more divided over the abortion issue in 1984 than they had been in 1980: In 1980, Reagan voters and Carter voters did not differ significantly in their attitudes toward abortion, but in 1984, Reagan voters were significantly more likely to be opposed to abortion than were Mondale voters. Nevertheless, only a small minority of voters considered abortion to be a major national issue, and the two voter groups were far more divided on several other issues than they were on abortion. There was no antiabortion consensus among the electorate as a whole, or among Reagan voters in particular. The level of approval for legalized abortion has, in fact, remained quite stable since 1973, and a popular base in favor of banning abortion seems to be lacking.
Decision ambivalence is a key concept in abortion literature, but has been poorly operationalised. This study explored the concept of decision ambivalence via an Abortion Decision Balance Sheet (ADBS) articulating reasons both for and against terminating an unintended pregnancy. Ninety-six women undergoing an early abortion for psychosocial…
Access to safe abortion hinges upon the availability of trained abortion providers. The American College of Obstetricians and Gynecologists supports education for students in health care fields as well as clinical training for residents and advanced practice clinicians in abortion care in order to increase the availability of trained abortion providers. The American College of Obstetricians and Gynecologists supports the expansion of abortion education and an increase in the number and types of trained abortion providers in order to ensure women's access to safe abortions. Integrated medical education and universal opt-out training policies help to lessen the stigma of abortion provision and improve access by increasing the number of abortion providers. This Committee Opinion reviews the current status of abortion education, describes initiatives to ensure the availability of appropriate and up-to-date abortion training, and recommends efforts for integrating and improving abortion education in medical schools, residency programs, and advanced practice clinician training programs.

The twin-reversed arterial perfusion (TRAP) sequence and development of an acardius are rare and severe complications in monozygotic twin pregnancy. Haemodynamic disturbances in placental perfusion via abnormal vascular anastomoses allow inter-twin transfusion to occur. Because of blood perfusion, one of the twins is poorly oxygenated and contains metabolic waste products. Retrograde placental perfusion leads to the formation of a non-viable malformed acardiac foetus. We studied the effects of haemodynamic disturbances in acardiac foetus on the development of the nervous system. The acardius was a product of a 32-weeks pregnancy. Caesarean section yielded a skin covered ovoid mass (size, 10 x 8 cm; weight, 220 g). The dissection of the acardiac twin showed a skin with hair and appendages, rudimentary lower limbs, vertebral column and brain mass. The rudimentary brain tissue was considerably disorganised structurally. We distinguished two main morphological forms of various appearances. In the centre, we observed a scarcely vascularised mass of tissue containing mature and immature neurones, glial cells and randomly distributed fibres. The mass of tissue appeared poorly differentiated, although there were some arrangements reminiscent of cerebral structures. Clusters of neurones provided a slight suggestion of nuclear or fibre structure. The cerebellar cortex was the only well recognisable structure. In the other fragment of the tissue, we found a slit cavity with ependymal outline and well-developed choroid plexus, which seemed to represent the 3rd ventricle. The scarcely vascularised disorganised tissue was surrounded by the highly vascularised one. It included many thin-walled sinusoid vessels. In some places, they were so concentrated that they resembled cavernous haemangioma. The spinal cord appeared comparatively well organised with a slightly dilated central canal. The morphological picture of the rudimentary brain tissue was similar to the picture of the

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.

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

Objectives The aims of the study were to determine the in vitro drug release of guar gum-coated capsules of ronidazole, and to evaluate the pharmacokinetics and efficacy of this formulation for the treatment of cats naturally infected with Tritrichomonas foetus. Methods The pharmacokinetics of ronidazole were evaluated in five healthy cats and five cats infected with T foetus. In a second step, the clinical efficacy of these capsules was evaluated by a controlled, randomised, double-blind clinical trial performed in 47 infected cats from French catteries. In this study, cats were randomly allocated to either the ronidazole treatment group (n = 25) or a placebo group (n = 22). Ronidazole (30 mg/kg) q24h for 14 days was administered to the treated cats. After 14 days of treatment, the presence of T foetus was tested by conventional PCR assay. Results In the pharmacokinetic study, a delayed peak plasma concentration was observed in healthy and infected cats, with no significant difference between these two groups (mean geometric mean of 9 h for time to maximum plasma concentration [Tmax], 21.6 µg/ml for time to maximum plasma concentration [Cmax] and 467.4 μg/h/ml for the area under the curve [AUC] in healthy cats; and 9.4 h for Tmax, 17.1 µg/ml for Cmax and 481 μg/h/ml for AUC in infected cats). In the clinical trial, T foetus was detected in 16% of cats from the treated group and 82% of cats from the placebo group at the end of the study ( P <0.001). No clinical signs of adverse drug reactions were observed. Conclusions and relevance Oral administration of guar gum-coated capsules of ronidazole at a dose of 30 mg/kg once daily for 14 days delays the peak plasma concentration and eradicates infection in most cases.

Forty years after the decriminalisation of abortion, what is society's view of this hard-fought right of women? Do they finally have the freedom to control their own bodies? The sociological view put forward here questions the professional positioning of caregivers faced with women requesting an elective abortion.
An analysis of the Roman Catholic Church's arguments against abortion rights suggests that its opposition is grounded more in outmoded views regarding women's roles than in concern for protecting fetal life. The 1st argument raised by Catholics and other anti-abortion forces is that abortion represents the unjustifiable destruction of a human life. A 2nd argument focuses on the status of the fetus as a person from the moment of conception, making abortion murder. A 3rd equates the fetus's potential for personhood with the pregnant woman's actual personhood. Despite the vehement sentiments expressed by Catholic leaders against abortion, the majority of Catholics support legal abortion. The assignment of personhood status to the fetus is contraindicated by actual practice in the Church, where aborted or miscarried products of early pregnancy are not baptized. Also, the Church does not forbid the taking of human life in war or to preserve political freedom. Finally, in countries such as Poland where abortion has been made illegal through religious pressure, there have been drastic cuts in health care and child care programs.
This article answers several questions relating to the moral issue of abortion, the value of life, and the rights of women. Women all over the world have been having abortions, legal or illegal, since time immemorial for reasons which are difficult to document. While legal and safe abortions do not compromise the physical and psychological health of the woman, more than ten thousand women suffer and die from complications of illegal abortions especially in countries where women are denied of their reproductive rights. Though abortion remained illegal in many countries such as Brazil and Latin America, legal restrictions do little to reduce the incidence of abortion. Meanwhile, the question on when the fetus has life is viewed differently by the scientific, medical, legal and religious communities. But even with the conviction that abortion involves taking the life of a person, it is indeed a responsibility to respect the views of other religions. Finally, although the decision to have abortion should belong to the couple, the last word should belong to the woman.

An adolescent's request for an abortion raises many ethical and practical issues. The social worker must help the girl weigh the various alternatives, resolve the abortion crisis to her own satisfaction, and view the experience as one episode in her growth toward adulthood. (Author)
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.
In the US, violence against abortion clinics is escalating. In July 1994, a doctor who performed abortions and one of his escorts was gunned down outside of an abortion clinic. In March of 1993, another doctor was killed outside of a clinic. That killing prompted passage of a federal law designed to protect abortion providers and clinics from violence. In addition to the individuals murdered, the number of violent incidents against abortion clinics increased four-fold to 250 in 1993. Some elderly physicians feel compelled to continue to perform the procedure instead of retiring because there are no young practitioners to replace them. These physicians note that the young practitioners have no experience with the deaths and illness which resulted from illegal abortions and have not been properly trained by their medical schools. The US Attorney General has dispatched federal marshalls to guard abortion clinics, and local police are increasing their protection of clinics. Abortion protestors say that the new federal law will cause some formerly peaceful protestors to resort to violence.

The adoption of a recent law on abortion (1978) makes available in Italy new statistics at both the national and regional levels. Following the official source of ISTAT, the abortion rate/100 livebirths in 1979 was about 28%, about 40% in the northern part of Italy, and only 16% in Mezzogiorno. This abortion rate, as an average data at the national level, corresponds to a normal position among similar rates in western countries; closer to EEC member states. But the regional variability seems a very interesting new aspect of the Italian tryptic (north, center, south) largely presented in many demographic indicators. 3 factors are presented as a possible explication of this variability: a real different attitude of women and couples towards abortion from cultural, religious, and political points of view; the coexistence of legal and illegal abortion despite the adoption of a new liberal law; and the very important disequilibrium in the distribution of structures and medical services available to assure abortions in different parts of the country. Some other demographic points related to abortion are also presented here, particularly in connection with age structure of women and their marital status. Future trends in abortion with subsequent effects on fertility are also discussed at the end of this article. The arguments follow 2 alternatives presented in Italy by the National Committee on Population and the Committee of Demographic Studies. (author's modified)

Almost 2 decades after the Supreme Court's landmark decision in Roe v. Wade, nurses' refusal to assist in abortions is still in question. There are about 1.6 million abortions a year. If Congress passes the Freedom of Choice Act, American women will be guaranteed continued access to abortion. But the effect of new regulations on 2 million nurses is the issue. Title VI of the Civil Rights Act of 1964 protects those who refuse to participate in abortions because of their religious beliefs. Several states have also enacted laws giving the right to health care workers to refuse to participate on ethical grounds. In Florida a staffer at an ambulatory care center was demoted after refusing to assist in an abortion. The appeals court ruled in the nurse's favor, stating that she should have been given a different assignment. Nurses who oppose abortion are advised by attorneys not to accept jobs where they are likely to be expected to assist in them. A New York City nurse refused to assist in an abortion and was reassigned to an administrative position, which she contested. The arbitrator restored her to her original position indicating that if the Freedom of Choice Act is passed it will not eliminate a nurse's right not to assist. In 1988 the so-called gag rule was issued barring caregivers at 4000 federally funded family planning clinics serving nearly 5 million women/year from recommending abortion to patients.
This publication seeks to explain the many facets of adolescent abortion: teenagers' need for access to safe abortion; the need for confidentiality in order to ensure safety; the real intent and effect of parental involvement laws; and the roles of parents and the state in safeguarding the health of pregnant teenagers. The first section looks at…

In early 2010, the Nebraska state legislature passed a new abortion restricting law asserting a new, compelling state interest in preventing fetal pain. In this article, we review existing constitutional abortion doctrine and note difficulties presented by persistent legal attention to a socially derived viability construct. We then offer a substantive biological, ethical, and legal critique of the new fetal pain rationale.
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.

Research on microbiota in cattle tick and the evaluation of its activity against other microorganisms can contribute to identify new molecules potentially useful to control infections caused by bacteria and protozoa. Biofilms pose increasing problems worldwide, mainly due to their resistance to antimicrobial therapies and host immune response. In this study we investigate the ability Rhipicephalus (Boophilus) microplus-associated bacteria may exhibit to produce anti-biofilm and trichomonicidal compounds. Gut, ovary, salivary glands, and Gené organ were collected from engorged R. microplus female. Homogenates of each tissue were inoculated onto 15 distinct culture media. Anti-biofilm and trichomonicidal activities were analyzed by culturing each bacterium isolated in a liquid medium. Results showed that R. microplus cattle tick microflora varies for different tissues. Bacteria belonging to different genera (Aeromonas, Bacillus, Brevibacillus, Castelaniella, Comamonas, Kocuria, and Microbacterium) were identified. Interestingly, all bacterial species found displayed pronounced activity against Staphylococcus epidermidis and Pseudomonas aeruginosa biofilms, and also against the cattle pathogen Tritrichomonas foetus, confirming the hypothesis that cattle tick could be a source of bacteria active against pathogens. This is the first study showing that bacteria isolated from a tick exert anti-biofilm and trichomonicidal activities.

Superhydrophilic vertically aligned carbon nanotubes (VACNT-O2) were used for the first time as scaffolds for photodynamic therapy (PDT) to induce inhibition of cell division in eukaryotic cells. VACNT-O2 scaffolds were produced on Ti substrates using plasma enhanced chemical vapor deposition technique and functionalized by oxygen plasma. Scanning electron microscopy (SEM) analysis was performed to characterize the surface changes of the protozoan and interaction with VACNT-O2. Characterization of lipid and total protein expression was performed with protozoa that were or not treated with PDT. Quantification of protein was conducted using Qubit fluorometer and separated on a polyacrylamide gel. SEM analysis showed the release of lipid vesicles by protozoa after the PDT. These vesicles were characterized by the PKH26 fluorescent probe. The results demonstrated a greater amount of protein released after PDT than in the control. When analyzing the protein material in polyacrylamide gel, a significant protein expression of approximately 65 kDa was found. A model identified the programmed death of Tritrichomonas foetus after the PDT was also proposed.

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.

Abortion has been legal and safe in Turkey since 1983, but the unmet need for safe abortion services remains high. Many medical practitioners believe that the introduction of medical abortion would address this. However, since 2012 there has been political opposition to the provision of abortion services. The government has been threatening to restrict the law, and following an administrative change in booking of appointments, some hospital clinics that provided family planning and abortion services had to stop providing abortions. Thus, the availability of safe abortion depends not only on permissive legislation but also political support and the ability of health professionals to provide it. We conducted a study among university medical school students in three provinces on their knowledge of abortion and abortion methods, to try to understand their future practice intentions. Pre-tested, structured, self-administered questionnaires were answered by 209 final-year medical students. The students' level of knowledge of abortion and abortion methods was very low. More than three-quarters had heard of surgical abortion, but only 56% mentioned medical abortion. Although nearly 90% supported making abortion services available in Turkey, their willingness to provide surgical abortion (16%) or medical abortion (15%) was low, due to lack of knowledge. Abortion care, including medical abortion, needs to be included in the medical school curriculum in order to safeguard this women's health service.
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.

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.

Serologic and morphologic studies were carried out with ewes and aborted fetuses, respectively, with regard to the Chlamydial infection in the flocks of some farms. The complement-fixation test was employed to examine a total of 656 blood serum samples. It was found that 20.2 per cent of these contained Chlamydial antibodies. Abortions were established with 6 to 8 per cent of the sheep in each flock. Material was sampled from 35 aborted fetuses. Featuring in the gross lesions of the fetal placenta in Chlamydial abortions were the wheat-bran type of whitish coatings on the surface. Characteristic histologic findings were desquamation, necroses, lympho-leukocytic infiltrations, and the partial deposits of calcium salts. Definite diagnostic value with the aborted fetuses were shown to have the lympho-histiocytic proliferations in the liver, adrenal glands, kidneys, lungs as well as the reticuloendothelial hyperplasia with the presence of gigantic cells of Langhans type in the mesenterial lymph nodes.
While the medical abortion (MA) drugs, mifepristone and misoprostol, have radically altered reproductive health practices around the world, there has been little field research on the sales and use of these drugs, especially in developing countries. This leaves the family planning community with many unanswered questions. While good profiles of contraceptive use are available for many countries and we have good technical data on the MA drugs' efficacy, dosages and regimens such as home dosage of misoprostol versus clinic dosage, we have very little information about the quantities of MA drugs sold, how they are used, where they are used, and, in the case of misoprostol, for what purposes. Sales data are available from one excellent commercial survey and from social marketing sales of mifepristone and misoprostol and these are presented. Acknowledging the sensitivity of the issue, especially in countries where abortion is severely restricted, the author makes a plea for careful additional research to shed light on an important and growing part of the international reproductive health picture.

This chapter provides a detailed description of 1st and 2nd trimester abortion techniques. In general, low morbidity is facilitated by preoperative diagnosis and evaluation, operator skill, sterile technique, avoidance of trauma, completeness of evacuation, and postoperative care. The 1st trimester technique used by the authors involves predilatation with laminaria, paracervical and intracervical blocks (anesthetic solution, 1% lignocaine with adrenaline), dilatation with either the Hawkin Ambler type or half-sized Pratt dilator, and evacuation with the van Lith or Karman type suction cannula. For 2nd trimester pregnancy termination, the authors use aspirotomy, a technique that combines the classic dilatation and evacuation method with suction curettage. An ergometrine maleate preparation is administered at the start of the procedure to produce sustained contraction of the uterine wall, decrease the chance of perforation, and accelerate the emptying process. Adrenaline in 1% lignocaine is used as a local anesthetic solution. A specially designed crushing forceps decreases the cervical dilatation required. Also presented is a technique for late 2nd trimester (16-20 weeks gestation) abortion that involves prostaglandins or the Finks dilatation and evacuation technique. The complication rate in the authors' unit for 3500 2nd trimester terminations was less than 0.5% but rose after 17 weeks of gestation.

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.

Induced abortion has been legal in New York State since 1970. In 1978 there were 1,540,000 legal abortions in the U.S.; more than half of the abortions take place within the 8th week of pregnancy; 75% of abortions are done on an outpatient basis, most of them not in large hospitals, but in free standing clinics. 30% of abortions are done under general anesthesia and require about 3 hours of hospitalization. 70% are done under local anesthesia, usually paracervical block, and require about 2 hours of hospitalization. Most women requesting abortions are between 19-24, nulliparous, and between the 7-10 week of gestation. Dilatation is usually done with Pratt dilators and evacuation by curettage. Between 1972-78 a total of 6,311,000 abortions were performed within the 1st 12 weeks; the mortality rate was 0.8/100,000. Probability of mortality is not only minimal between the 1st-8th week, but is the same whether the abortion is done in a hospital or an outpatient clinic. Rates of serious complications range from 0.3% for the 1st 6 weeks to 0.8% from the 11-12th week. Rates for serious and minor complications taken together are 7.8%. Serious complications occur more frequently in patients under total anesthesia, especially cervical laceration and hemorrhage. Induced abortion does not increase the risk of secondary sterility. Between the 12th-17th week, abortion is usually done by dilatation and evacuation, and after the 17th week by drug infusion.
Topics of interest to women were discussed at a 1-day conference. 85% of the participants were women. The theme was, "Can the abortion rate be changed?" The number of abortions rose from 19,919 in 1985 to 21,199 in 1988, a rate of 6%. The previous 8 years had shown a steady decrease from 25,662 in 1977. This was especially pronounced in women under 25. The birth rate climbed 10% at the same time. With the exception of Ireland, free access to abortion is the rule in the majority of the countries of Europe. Prenatal diagnosis (PD)--chorionic villus biopsies and amniocentesis--was begun in 1970 in Denmark. Investigation of placental biopsies was begun in 1983. The number of diagnoses rose sharply after this. From 1980-1988 the number of legally induced abortions was between 20,000 and 23,000. The number of spontaneous abortions rose from 8000 to over 9000. There were approximately 70 abortions because of PD. This figure reached 133 in 1980. Women aged 35 and above have made increasing use of PD. After PD was brought about, the number of legal abortions dropped. 42% of pregnant women over 35 carried to term;l 46% chose legal abortion. In the 40-year age group, the figures were 23% and 60%, respectively. Data on 140 abortion seekers (AS) (ages 16-21) in Denmark (73.6% replied) were compared to 201 sexually active youngsters who were not pregnant. The abortion seekers showed no difference from those not pregnant. However, more among the AS had started sexual intercourse with the 1st 2 years after menarche; they had had many different sexual partners. 73.9% of the AS used contraception at 1st intercourse, compared to 82.1% of those not pregnant. In the abortion-seeking group, about 1/3 became pregnant despite the use of contraception (generally a condom). 44% had most recently used a pill. In 1973, a law was passed permitting abortion before the end of the 12th week of pregnancy. In the last 17 years, abortions have become more frequent among young career women. The
This article provides views on abortion by demonstrating women's retrospective accounts of their abortion experiences. Women's accounts of their abortion experiences are socially constructed both at the time of the abortion and in subsequent years in their lives. Some women reflect on their past abortion as the right decision; however, some also feel varying degrees of pain, grief, and loss. Many view their abortions as mistakes. Profiles of four women are presented in this article to provide several critical points on a continuum pertaining to study participants' retrospective satisfaction with an abortion experience. Based on the profiles, various emotional reactions are possible to occur after abortion and those retrospective interpretations of the experience change as personal growth and circumstances prompt women to reflect about the original experience. It was also documented that the satisfied group in the study was the one composed of women still involved with the partner with whom they became pregnant. With an open conversation on the emotional effects of abortion, women will be able to help inform and transform politicized abortion debates.

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

About 20% of thymus lymphocytes from neonatal calves formed spontaneous (E) rosettes with SRBCs in medium consisting of 50-100% foetal calf serum (FCS); other media were less satisfactory. FCS was necessary both to allow rosette formation to occur and to maintain stability of the rosettes once formed. Rosettes were stable at 0 degrees C but unstable at 18 degrees C and 37 degrees C. Dead thymus cell (sodium azide treated) did not form rosettes. Treatment of thymus cells with antiserum to bovine Ig-inhibited rosette formation, but this inhibition was considered non-specific since it also occurred with normal rabbit serum. Treatment of SRBCs with neuraminidase slightly enhanced rosette formation by thymus cells, but did not induce peripheral blood lymphocytes to form rosettes. Rosette formation did not occur under a variety of conditions with normal or neuraminidase-treated human, horse, pig, rabbit, guinea-pig, chicken or autologous RBCs. SRBC rosette forming cells were also found in lymph nodes (2-14%) and spleen (less than 5%), but rarely or never in peripheral blood and bone marrow of calves and adults. In foetuses at 80 days of gestation, 49% of thymus cells formed E rosettes. Foetal lymph node cells formed E rosettes at 160 days and spleen at 180 days. Cells with membrane-bound Ig were observed by IFT; their distribution did not coincide with the occurrence of E rosettes. E-rosette formation might be a marker for a subpopulation of bovine T cells.

Cytogenetic data on products of conception from spontaneous abortions studied over a 10-year period have been reviewed for double trisomies. A total of 3034 spontaneous abortions were karyotyped between 1986 and 1997. Twenty-two cases with double trisomy, one case with triple trisomy, and a case with a trisomy and monosomy were found. The tissues studied were mostly sac, villi, or placenta. The gestational age ranged from 6 to 11 weeks and the mean age was 8.2 +/- 1.7 (SD) weeks. The mean maternal age in years was 35.9 +/- 5.3. Of the twenty-two cases, four were mosaics. All but two of the cases involved autosomal aneuploidies. The double trisomies included chromosomes 2, 4, 5, 7, 8, 12, 13, 14, 15, 16, 17, 18, 20, 21, and 22. The chromosomes that were trisomic in more than one double trisomy case were numbers 16 (8 cases), 8 (5 cases), 15 (4 cases), 2, 13, and 21 (3 cases each), and 5, 7, 14, 18, 20, 22, and X (2 cases). The triple trisomy involved chromosomes 18, 21, and X. The monosomy and trisomy case was a mosaic, with a monosomy 21 in all cells and some cells also with a trisomy 5. The double trisomies cited for the first time in this study were 4/13, 5/16, 8/14, 8/15, 14/21, 15/20, and 7/12. The pooled mean maternal age for double trisomy cases (34.1 +/- 5.7 years) was higher than that for single trisomy cases (31 +/- 6.1 years). The difference was statistically significant at P = < 0.001. The pooled mean gestational age of spontaneous abortions was lower for double trisomy (8.7 +/- 2.2 weeks) than for reported single trisomy cases (10.1 +/- 2.9 weeks). This difference is also statistically significant at P = < 0.001. The sex ratio among double trisomies was 15 females to 13 males. This difference was not statistically significant from the expected 1:1.

Bovine coronaviruses, like other animal coronaviruses, have a predilection for intestinal and respiratory tracts. The viruses responsible for enteric and respiratory symptoms are closely related antigenically and genetically. Only 4 bovine coronavirus isolates have been completely sequenced and thus, the information about the genetics of the virus is still limited. This article reviews the clinical syndromes associated with bovine coronavirus, including pneumonia in calves and adult cattle, calf diarrhea, and winter dysentery; diagnostic methods; prevention using vaccination; and treatment, with adjunctive immunotherapy.

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

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

A survey of 86 university abortion programs was carried out in December 1973, a year after the Supreme Court decision on abortion. In comparing the results of the questionnaires used in the survey, California, Colorado, Hawaii, Maryland, and New York are considered separately as established states because of their prior liberalized abortion laws, and the other states are referred to as new states. At least 52% of all centers where abortions are performed have less than 500 procedures annually. 31.6% of the new states and 50% of the established states perform menstrual extraction. 65% of all centers providing abortion services have investigative programs. No significant differences exist between the centers of new and established states. It appears that significant numbers of physicians are not exposed to the management of abortions. Less than 1/3 of university programs provide educational experience for outside physicians. It was made evident by the survey that many university departments have not made elective abortion an integral part of the service and educational responsibilities of obstetrics and gynecology.

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

A survey of 1734 married women in Brazil was conducted to determine the incidence of abortion. The results show that 159, or 9.2% stated that they had had at least 1 induced abortion, either within marriage or when they were single. Mean age of women with a history of induced abortion was 35.05 years, compared with 34.38 years for women who had had live births but not abortion, and 32.58 for women who had had neither live-birth nor abortion. When age at marriage, rather than age at interview was considered, the incidence of abortion was apparently greater among those marrying at earlier ages, although consideration should also be given to the fact that the chances of live births are also inversely related to age at marriage. Generally, married women with a history of abortion desired no more children compared with other married women; they were more likely to have had experimented with various contraceptive measures in the past; more likely to be currently practicing contraception; and were more ready to accept the contraceptive pill if it had been available. The lower the social status (either of the wife's father/husband) and the 'darker' the informant's skin color, the greater the tendency to use coitus interruptus; the safe period; and other methods. Also, the lower the social status and the darker the skin, the less likely was the informant ever to have used contraceptive devices. It was concluded that in consideration of the variables considered, the differences between wives with and without a history of abortion were generally not great. Any significant differences noted were attributed to variations in economic security. Widespread knowledge and practice of contraception, as well as economic development and higher average income, will reduce the induced abortion rate in Brazil.
In early 1991 the abortion debate in Poland entered its new stage. The prolife and prochoice options had already clashed in the early 1930s over a new penal code and backstreet abortions. According to the code of 1932, induced abortion was allowed in cases of rape, incest, or for medical indications. Abortion was legalized in 1956, but subsequently it came under attack from Catholic circles, and by 1989 the Unborn Child Protection Bill was drafted which criminalized abortion. Only 11% of Polish women use modern contraceptives. The less efficient methods are the most prevalent: the natural method (Ogino-Knaus calendar), 35% of couples; coitus interruptus, 34%; condoms, 15%; oral contraceptives 7%; chemical spermicides, 2.5%; and the IUD 2%. According to size of Catholic Church estimate there are 600,000 abortions yearly. In contrast, official statistics indicate that the number of abortions is decreasing: 137,950 in 1980; 105,300 in 1988; 80,100 in 1989; 59,400 in 1990. In January 1991 the Constitutional Tribunal dismissed the motion of the Polish Feminist Association against the restrictive regulations of the Ministry of Health concerning abortion. After a parliamentary stalemate on the Unborn Child Protection Bill a commission consisting of 46 persona (1.2 of them women, 20 persons from the prochoice and 24 from the prolife lobby) continued the debate on the bill. Public opinion polls conducted by independent groups in November 1990 showed that about 60% of citizens were against the Senate's draft. Since then interest in the abortion issue has dwindled, and only 200 women and men took part in a prochoice demonstration in front of the parliament on January 25, 1991. In the spring of 1989 and in September 1990 thousands had participated in similar demonstrations. The prevailing attitude is that if the antiabortion bill is passed nothing can be done.
Mortality by abortion has continuously decreased over the past fifty years in Chile. In fact, maternal death as a result of an induced abortion has become an exceptionally rare phenomenon in epidemiological terms (a risk of 1 in 4 million pregnant women of fertile age or 0.4 per 100,000 life births for abortion of any type, excluding ectopic pregnancy). After abortion became illegal in 1989, deaths related to abortion continued to decrease from 10.8 to 0.39 per 100,000 live births. This scientific fact challenges the common notion that less permissive abortion laws lead to greater mortality associated with abortion.

This research examines 23 different laws passed by state governments in an effort to restrict the number of abortions. It assesses both laws passed and laws actually enforced after the Supreme Court permitted states to restrict access to abortion in 1989. None of the policy actions by state governments has had a significant impact on the incidence of abortion from 1982 to 1992. Abortion rates continue to reflect past abortion rates, the number of abortion providers, whether the state funds abortions for Medicaid-eligible women, urbanism, and racial composition of the population. Recent restrictive policies have not affected these trends.

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.

Cytogenetic analysis was performed on 1142 couples with recurrent pregnancy loss. The frequency of major chromosomal abnormalities per couple was 4.8%. Among 771 couples who had only abortions, the rate of rearrangement did not correlate with the number of abortions. The highest incidence of cytogenetic abnormalities (6.6%) was found in 256 couples with abortion and a normal child. With regard to pregnancy outcome, no unbalanced fetal karyotype was found in prenatal diagnoses, and 40 normal children were born. The risk of unbalanced fetal karyotype is therefore low, but probably high enough for these couples to be offered the possibility of a prenatal diagnosis.
This paper discusses the Brazilian Supreme Court ruling on the case of anencephaly. In Brazil, abortion is a crime against the life of a fetus, and selective abortion of non-viable fetuses is prohibited. Following a paradigmatic case discussed by the Brazilian Supreme Court in 2004, the use of abortion was authorized in the case of a fetus with anencephaly. The objective of this paper is to analyze the ethical arguments of the case, in particular the strategy of avoiding the moral status of the fetus, the cornerstone thesis of the Catholic Church.

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.

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.

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

One in four pregnancies worldwide is voluntarily terminated. Approximately 20 million terminations are performed under unsafe conditions, mostly in developing countries with restrictive abortion laws. A total of 100 consecutive abortion-seekers were interviewed, to ascertain their knowledge and perceptions on the Nigerian Abortion Law. The majority (55.0%) of the respondents were students. Most of them (97%) had at least secondary education and the majority (62.0%) were within the 20-24 years age range. Only 31.0% of the women interviewed were aware of the Nigerian Abortion Law. While 16% perceived the law as being restrictive, 2% opined that' it was alright'; 1% perceived it as very restrictive and 12% had no opinion on the abortion law. Knowledge of the abortion law had no significant relationship with either the educational level of the respondent or the number of previous pregnancy terminations and overall demand for abortion services. It is necessary to ensure a wide dissemination of the abortion law and its provisions to the Nigerian public, in order to arm them with the necessary information to participate actively in debates on abortion law reforms.

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

Globally, abortion has emerged as a critical determinant of maternal morbidity and mortality. The Ghana government amended the country's abortion law in 1985 to promote safe abortion. This article discusses the findings of a qualitative study that explored the decision-making experiences of 28 female abortion seekers aged between 15 and 30 years in Ghana. Key findings from the study are that individuals claimed autonomy in their abortion decisions; underlying the abortion decisions were pragmatic concerns such as economic difficulties, child spacing, and fear of parental reaction. In conclusion, we examine the health implications of Ghanaian women's abortion decisions.

Myxoma virus (MYXV), a leporide-specific poxvirus, represents an attractive candidate for the generation of safe, non-replicative vaccine vector for non-host species. However, there is very little information concerning infection of non-laboratory animals species cells with MYXV. In this study, we investigated interactions between bovine cells and respectively a wild type strain (T1) and a vaccinal strain (SG33) of MYXV. We showed that bovine KOP-R, BT and MDBK cell lines do not support MYXV production. Electron microscopy observations of BT-infected cells revealed the low efficiency of viral entry and the production of defective virions. In addition, infection of bovine peripheral blood mononuclear cells (PBMC) occurred at a very low level, even following non-specific activation, and was always abortive. We did not observe significant differences between the wild type strain and the vaccinal strain of MYXV, indicating that SG33 could be used for new bovine vaccination strategies.

A focus-group study of adolescents from cities across the United States revealed that they lacked accurate knowledge about abortion and the laws governing it. Most expressed erroneous beliefs about abortion, describing it as medically dangerous, emotionally damaging and widely illegal. The study also revealed that antiabortion views, conservative morality and religious beliefs were the primary sources of these adolescents' attitudes toward abortion. In general, the participants in the study said they were personally opposed to abortion, but supported its continued legality as a woman's choice. Although most of the teenagers expressed positive feelings toward parents, they did not feel that mandatory parental involvement would be helpful, and in some cases could cause harm.

Abortion has long been an issue of concern for professional groups in many fields, such as medicine, nursing, religion, feminist rights, psychology, and social work. Although these groups hold differing views on abortion as well as eugenics health care law revision, they share a consensus that counseling services should be provided for abortion in order that women are sufficiently informed to make a sound decision on whether or not to have an abortion. Thus, this paper discusses in detail counseling service in terms of background, workflow and approaches, and interdisciplinary integration, as well as offers suggestions for future development. Hopefully, this can serve as a reference for concerned about women's reproductive health and obstetrics service quality.

For most of the 20th Century, restrictive abortion laws were in place in continental Latin America. In recent years, reforms have caused a liberalizing shift, supported by constitutional decisions of the countries' high courts. The present article offers an overview of the turn toward more liberal rules and the resolution of abortion disputes by reference to national constitutions. For such purpose, the main legal changes of abortion laws in the last decade are first surveyed. Landmark decisions of the high courts of Argentina, Bolivia, Colombia, and Mexico are then analyzed. It is shown that courts have accepted the need to balance interests and competing rights to ground less restrictive laws. In doing so, they have articulated limits to protection of fetal interests, and basic ideas of women's dignity, autonomy, and equality. The process of constitutionalization has only just begun. Constitutional judgments are not the last word, but they are important contributions in reinforcing the legality of abortion.
Legal abortions are authorized medical procedures, and as such, they are or can be recorded at the health facility where they are performed. The incidence of illegal, often unsafe, induced abortion has to be estimated, however. In the literature, no fewer than eight methods have been used to estimate the frequency of induced abortion: the "illegal abortion provider survey," the "complications statistics" approach, the "mortality statistics" approach, self-reporting techniques, prospective studies, the "residual" method, anonymous third party reports, and experts' estimates. This article describes the methodological requirements of each of these methods and discusses their biases. Empirical records for each method are reviewed, with particular attention paid to the contexts in which the method has been employed successfully. Finally, the choice of an appropriate method of estimation is discussed, depending on the context in which it is to be applied and on the goal of the estimation effort.
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.

This document summarizes a sample of significant activities and events undertaken by Roman Catholics in response to the US Supreme Court's Roe vs. Wade decision legalizing induced abortion. The summaries begin with the 1966 creation of the National Right to Life Committee and cover opposition of Catholic bishops to the Roe decision, the organization of the National Committee for a Human Life Amendment (NCHLA), the mock investiture of a female pope by Catholics for a Free Choice, dismissal of a pro-life priest from the Jesuits, excommunication of various women because of their work with pro-choice agencies or ones that provided abortion services, meetings of the National Conference of Catholic Bishops (NCCB) with presidential candidates, NCHLA lobbying for the Hyde Amendment, open letters and advertisements published by CFC, the effort of Abortion Rights Mobilization to strip the Catholic church of its tax-exempt status, the Vatican order for all priests to leave political office, actions taken by nuns to support the pro-choice position, the proposal of the "seamless garment" argument under the principle of the "consistent ethic of life," initiation of the post-abortion reconciliation project, the actions of Catholic politicians, the filing of amicus curiae briefs, support of bishops for Operation Rescue, forums on abortion conducted by an Archbishop, the Catholic Statement on Pluralism and Abortion, targeting by bishops of pro-choice candidates for sanctions and excommunication, testimony and lobbying in opposition of the Freedom of Choice Act, false accusations about the 1994 International Conference on Population and Development leveled by bishops, lobbying by bishops in support of a ban on late-term abortions, lobbying to increase the access of low-income women to abortion, and consideration by the bishops of reinstituting "meatless Fridays" to express Catholic opposition to "attacks on human life and dignity."
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.

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.

In 1974, a law was passed in Sweden allowing abortion on demand. Studies are now being undertaken to determine the effect of this law in 3 important areas: abortion counselling, abortion frequency, and possible means of psychological assistance for those who undergo abortions. Abortion must be studied as it affects the entire reproductive chain, in which there are 4 main links: frequency of sexual intercourse, physiological fertility, motivation to have children, and measures taken for birth control. In an agricultural society, children have a value as part of the work force and for retirement security; in a modern society, children have a much more abstract value. The reproductive chain is also affected by the increasing number of unmarried couples living together. There is a need to interview individuals and families to determine "fertility choice behavior", which can help to illuminate motivations for becoming pregnant or seeking abortion. These studies could help determine the perceived advantages and disadvantages of having children and what factors influence "fertility choice behavior".

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.

This study evaluated the effects of thiamine pyrophosphate (PPT) on the biochemical profiles of full-term rabbit foetuses that were subjected to experimental ischemia followed by 24h reperfusion. A total of 16 gestating rabbit dams were divided into two groups, one of which was treated by administering PPT and subjected to a process ischemia. During this interval, fetal blood samples were drawn from each dam (in the ischemia group) at 0, 15 and 45min. Ischemia for 15 and 45min was not associated with changes in lactate levels of the Ischemia group foetuses. However, in the foetuses in the reperfusion groups without PPT lactate levels were significantly higher after 15 and 45min of arterial occlusion compared to time zero. These results demonstrate that PTT alters some acute and some longer-term biochemical outcomes of uterine ischemia perhaps important in preserving energy metabolism under hypoxic conditions.

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

Four decades after Roe v. Wade, abortion remains highly contentious, pitting a woman's right to choose against a fetal claim to life. Public health implications are staggering: the US annual total of more than one million induced abortions equals nearly half the number of registered deaths from all causes. Sentiment regarding abortion is roughly evenly split among the general public, yet fundamental debate about abortion is largely absent in the public health community, which is predominantly supportive of its wide availability. Absence of substantive debate on abortion separates the public health community from the public we serve, jeopardizing the trust placed in us. Traditional public health values-support for vulnerable groups and opposition to the politicization of science-together with the principle of reciprocity weigh against abortion. Were aborted lives counted as are other human lives, induced abortion would be acknowledged as the largest single preventable cause of loss of human life. Lay Summary: Four decades after Roe v.

Background Abortion is a serious public health issue, and it poses high risks to the health and life of women. Yet safe abortion services are not readily available because few doctors are trained to provide such services. Many doctors are unaware of laws pertaining to abortion. This article reports survey findings on Malaysian medical students’ attitudes toward abortion education and presents a case for including abortion education in medical schools. Methods and Results A survey on knowledge of and attitudes toward abortion among medical students was conducted in two public universities and a private university in Malaysia in 2011. A total of 1,060 students returned the completed questionnaires. The survey covered about 90% of medical students in Years 1, 3, and 5 in the three universities. About 90% of the students wanted more training on the general knowledge and legal aspects of abortion, and pre-and post-abortion counseling. Overall, 75.9% and 81.0% of the students were in favor of including in medical education the training on surgical abortion techniques and medical abortion, respectively. Only 2.4% and 1.7% were opposed to the inclusion of training of these two methods in the curriculum. The remaining respondents were neutral in their stand. Desire for more abortion education was associated with students’ pro-choice index, their intention to provide abortion services in future practice, and year of study. However, students’ attitudes toward abortion were not significantly associated with gender, type of university, or ethnicity. Conclusions Most students wanted more training on abortion. Some students also expressed their intention to provide abortion counseling and services in their future practice. Their desire for more training on abortion should be taken into account in the new curriculum. Abortion education is an important step towards making available safe abortion services to enable women to exercise their reproductive rights. PMID:23300600
Calcium and phosphorus represent building material for bones. The supplier of these bone minerals is the hormone calcitriol, which originates from vitamin D, itself made by sunshine in human skin. Requirement for bone minerals is highest during phases of rapid growth, and no one grows faster than the foetus and the infant, making them particularly vulnerable. Deprivation of calcium, whether through low calcium intake or low vitamin D, leads to serious health consequences throughout life, such as hypocalcaemic seizures, dilated cardiomyopathy, skeletal myopathy, congenital and infantile rickets, and osteomalacia. These 5 conditions are often summarised as 'symptomatic vitamin D deficiency', are fully reversible but also fully preventable. However, the increasing prevalence of rickets and osteomalacia, and the deaths from hypocalcaemic cardiomyopathy, demand action from global health care providers. Clarification of medical and parental responsibilities is a prerequisite to deliver successful prevention programmes. The foetus and infant have the human right to be protected against harm, and vitamin D supplementation has the same public health priority as vaccinations.

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

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

For decades, the induction of fetal demise has been used before both surgical and medical second-trimester abortion. Intracardiac potassium chloride and intrafetal or intra-amniotic digoxin injections are the pharmacologic agents used most often to induce fetal demise. In the last several years, induction of fetal demise has become more common before second-trimester abortion. The only randomized, placebo-controlled trial of induced fetal demise before surgical abortion used a 1 mg injection of intra-amniotic digoxin before surgical abortion at 20-23 weeks' gestation and found no difference in procedure duration, difficulty, estimated blood loss, pain scores or complications between groups. Inducing demise before induction terminations at near viable gestational ages to avoid signs of life at delivery is practiced widely. The role of inducing demise before dilation and evacuation (D&E) remains unclear, except for legal considerations in the United States when an intact delivery is intended. There is a discrepancy between the one published randomized trial that used 1 mg intra-amniotic digoxin that showed no improvement in D&E outcomes and observational studies using different routes, doses and pre-abortion intervals that have made claims for its use. Additional randomized trials might provide clearer evidence upon which to make further recommendations about any role of inducing demise before surgical abortion. At the current time, the Society of Family Planning recommends that pharmacokinetic studies followed by randomized controlled trials be conducted to assess the safety and efficacy of feticidal agents to improve abortion safety.
An abortion-attitude scale and an abortion knowledge inventory that may be used by health educators, counselors, and researchers in order to assess attitudes toward abortion, knowledge of abortion, and to determine the relationship between these 2 factors was developed. The information obtained can be used to assist in the development of educati onal programs and curricula and to aid counselors in becoming more helpf ul to the students. The instruments were constructed from a sample of undergraduate students at Brooklyn College of the City University of New York. All students were from randomly selected classes and participated voluntarily. The instruments were completed during the summer of 1973. The Abortion-Attitude Scale is a 5-point summated rating scale designed to determine each subject's positive or negative attitude toward abortion as a birth control method. The Abortion-Knowledge Inventory has a 4-option multiple choice format, designed to determine each subject's knowledge about abortion. The mean attitude score for the final administration to 527 students was 116.6 which falls almost halfway between 90 (undecided) and 150 (fully in favor), indicating a generally liberal attitude. The mean knowledge scores for the 527 students was 16.1 which is equal to a percentage score of 54%. In order to determine the relationship between attitudes toward and knowledge of abortion as birth control, scores on the 2 scales were correlated. The results indicate a moderate and statistically significant relationship. It appears that with more knowledge about abortion the students tended to have more favorable attitudes.

Listerial keratoconjunctivitis ('silage eye') is a wide spread problem in ruminants causing economic losses to farmers and impacts negatively on animal welfare. It results from direct entry of Listeria monocytogenes into the eye, often following consumption of contaminated silage. An isolation protocol for bovine conjunctival swabbing was developed and used to sample both infected and healthy eyes bovine eyes (n=46). L. monocytogenes was only isolated from one healthy eye sample, and suggests that this organism can be present without causing disease. To initiate a study of this disease, an infection model was developed using isolated conjunctiva explants obtained from cattle eyes post slaughter. Conjunctiva were cultured and infected for 20 h with a range of L. monocytogenes isolates (n=11), including the healthy bovine eye isolate and also strains isolated from other bovine sources, such as milk or clinical infections. Two L. monocytogenes isolates (one from a healthy eye and one from a cattle abortion) were markedly less able to invade conjunctiva explants, but one of those was able to efficiently infect Caco2 cells indicating that it was fully virulent. These two isolates were also significantly more sensitive to lysozyme compared to most other isolates tested, suggesting that lysozyme resistance is an important factor when infecting bovine conjunctiva. In conclusion, we present the first bovine conjunctiva explant model for infection studies and demonstrate that clinical L. monocytogenes isolates from cases of bovine keratoconjunctivitis are able to infect these tissues.
In both the Republic of Ireland and the North of Ireland, it is impossible to obtain a legal abortion unless the life of the mother would otherwise be lost. Thus, an estimated 10-12,000 women travel from Ireland to England each year to have an abortion. These women can receive support from the Irish Women's Abortion Support Group (IWASG) which is made up of volunteer women who are Irish or of Irish descent. The IWASG provides accommodations, emotional and practical support, and information about how to obtain an abortion in the UK. It makes appointments, negotiates fees, and monitors services offered. The group can also provide financial assistance to women in need. IWASG liaises with pro-choice groups in Ireland, such as the underground Women's Information Network (WIN), which has branches in Dublin, Galway, and Cork. WIN provides confidential, nondirective counseling to women in need. Abortion is a very difficult choice for Irish women because of the legal strictures and because of the guilt which often results from government and religious propaganda. The prospect of finding their way around London is often as daunting to the Irish women as the procedure itself, and many of the women travel to England absolutely alone with no one at home even aware of what they are doing. IWASG is seeking new members to help them support these women. For information, write IWASG, 52 Featherstone Street, London ECIY 8RT.

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.

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.

There will always be women who need abortions after 12 weeks of pregnancy, and their reasons are often compelling. Although second trimester abortions carry relatively more risks than first trimester abortions, abortion is still very safe throughout the second trimester if done in safe conditions. This paper is about law and policy on second trimester abortions, which are allowed on more restrictive grounds than first trimester abortions in most countries, if at all. It focuses on countries where most or at least some second trimester abortions are allowed, including in Europe, where many women are still forced to travel for second trimester abortions, and countries in the developing world, where most second trimester abortions remain unsafe. The need for second trimester abortion should be met in a safe, timely and sympathetic manner. Abortion should be legal at the woman's request up to 24 weeks and on therapeutic grounds after that, and no other barriers or hurdles should be imposed on women seeking second trimester abortion. In-depth, country-based research is needed, to bring out the facts on second trimester abortion, as evidence of why it should be treated as a legitimate form of women's health care and supported in public health policy.

Access to abortion remains a controversial issue worldwide. In Ireland, both north and south, legal restrictions have resulted in thousands of women travelling to England and Wales and further afield to obtain abortions in the last decade alone, while others purchase the 'abortion pill' from Internet sources. This paper considers the socio-legal context in both jurisdictions, the data on those travelling to access abortion and the barriers to legal reform. It argues that moral conservatism in Ireland, north and south, has contributed to the restricted access to abortion, impacting on the experience of thousands of women, resulting in these individuals becoming 'abortion tourists'.

Bovine trichomonosis (BT) is a sexually transmitted disease that is considered a cause of early reproductive failure in cattle under extensive management conditions. Recently, Tritrichomonas foetus was detected in 41.5% of herds from one representative beef cattle breed (Asturiana de la Montaña; AM) reared in traditional mountain systems in Spain. The objective of the present study was to evaluate the effect of BT on reproductive performance and the economic consequences in AM herds. The benefits of a control program based on testing and culling infected bulls were also studied by comparing T. foetus prevalence and reproductive data before and after the implementation of the control measures. In infected herds, T. foetus infection increased calving intervals by 79 days (P<0.0001) and resulted in a higher percentage of cows-not-in calf (36% vs. 19%; P<0.001). An economic analysis showed that BT could reduce income by 68.7% in AM herds. The implementation of the control program decreased calving intervals (P<0.0001) and increased calving percentage (P<0.05). T. foetus prevalence showed a significant decline compared with the prevalence before implementing the control program (P<0.05). Nevertheless, after 2 years, the herd prevalence did not decrease (12.7-13.6%; P>0.05) and the herd incidence was 22.72%. The testing and culling policy was effective in improving reproductive efficiency but the complete elimination of BT without substantial changes in management appears unlikely because putative risk factors associated with the disease are present in the management of this breed.

As for most of its Caribbean neighbours, Trinidad and Tobago's leading cause of maternal morbidity is unsafe abortion. Yet activism to introduce public policy and legislation that effectively address this aspect of women's reproductive rights and health has been met with public outcry. With almost hysterical opposition coming from certain religious quarters, there is the unsubstantiated impression that Trinidadians are overwhelmingly opposed to abortion law reform. A national survey was therefore carried out of people's knowledge and views on the current abortion law in Trinidad and Tobago. The survey found that although almost half of respondents had an unfavourable perception of abortion, more than half of them were in favour of broadening the legal grounds for accessing terminations. Incest, rape and danger to a woman's life were cited as the most significant circumstances under which abortions should be permitted. The vast majority of respondents agreed that voting on abortion law reform by members of the legislature should not be based on personal beliefs. The findings demonstrate that there is not the degree of opposition to abortion law reform that is widely assumed. On the other hand, given the wide variance of views and perceptions, we argue that public health concerns and human rights should always trump public opinion.
Between February 2012 and March 2015, the claim that sex selection abortion was taking place in Britain and that action needed to be taken to stop it dominated debate in Britain about abortion. Situating an analysis in sociological and social psychological approaches to the construction of social problems, particularly those considering “feminised” re-framings of anti-abortion arguments, this paper presents an account of this debate. Based on analysis of media coverage, Parliamentary debate and official documents, we focus on claims about grounds (evidence) made to sustain the case that sex selection abortion is a British social problem and highlight how abortion was problematised in new ways. Perhaps most notable, we argue, was the level of largely unchallenged vilification of abortion doctors and providers, on the grounds that they are both law violators and participants in acts of discrimination and violence against women, especially those of Asian heritage. We draw attention to the role of claims made by feminists in the media and in Parliament about “gendercide” as part of this process and argue that those supportive of access to abortion need to critically assess both this aspect of the events and also consider arguments about the problems of “medical power” in the light of what took place.

Obtaining reliable information about induced abortion is notoriously difficult, especially where abortion is illegal. This article describes methods used in a study of illegal induced abortion among village women in Northeast Thailand. A variety of methods were used to gather in-depth qualitative data on abortion experiences including a randomized interview survey on reproductive health, in-depth interviews with women who had experienced an induced abortion in the last two years, and the use of vignettes in focus group discussions with men and women. The survey provided a broad overview of the extent of the experience of abortion. In-depth interviews through social networks proved more successful for obtaining reliable accounts of abortions and suggest that survey results were underestimates. Focus groups discussed the situational ethics involved in abortion decisions. Within an appropriate context and study design, it is possible to obtain highly sensitive information while respecting the privacy of informants.

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

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

This is a qualitative research based on the social phenomenology approach, performed in 2010 with eight adolescents who experienced abortion and were assisted in a philanthropic hospital institution in the state of Minas Gerais. This research aimed at understanding the experience and care needs regarding adolescents in an abortion situation. The results show that the pregnancy impact led to the fear of non acceptance by the family and at the same time, the feeling of happiness for the possibility of being a mother. The abortion experience was marked by suffering and the care provided was considered satisfactory, being highlighted the need for more attention and information. The adolescents plan to continue their studies and have in mind the possibility of a new pregnancy. The planning of preventive actions aimed at this audience, and the development of new scientific investigations that include the perspective of family members and health professionals begin to emerge.

Two experimental mouse models were tested for their suitability in measuring virulence of two human and two bovine isolates (types Ia and III) of group B streptococci. In the first model, the kinetics of the number of bacteria in the spleen, liver, and placenta of mice inoculated intravenously on day 16 of pregnancy were monitored for 48 h after infection. In the second model, lethality and abortion were recorded for mice inoculated on day 13 of pregnancy. Levels of colonization in spleens or livers and lethality were significantly greater (P less than 0.001) for human isolates than for bovine isolates. In contrast, no statistically significant differences in the ability to colonize placentas and to induce abortions were noted between human and bovine isolates. The results showed that pregnant mice were more sensitive than nonpregnant mice to a challenge with group B streptococci. The results also suggest that placental colonization and abortion could be a suitable mouse model in evaluating the virulence of human and bovine isolates of group B streptococci. PMID:3880731

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.
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 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.

Around one-quarter of Australian women will have an abortion during their lifetime but access is affected by the way health care providers interpret the law about abortion. In Queensland and New South Wales abortion is a criminal offence although it is defensible in certain circumstances. Drawing on interviews with 22 doctors who provide abortion services to women in New South Wales and Queensland, this article examines doctors' responses to two common scenarios in which women may request an abortion. The two scenarios discussed in this article are a request for a first trimester abortion in circumstances where the woman does not feel ready to have a baby; and a request for abortion in the second trimester where the fetus has been diagnosed with an abnormality. This article explores doctors' understanding of the law related to the provision of abortion in these two States and their views about the effect of the law on their practice.
Counseling abortion seekers can be a very difficult task. Some patients can be very knowledgeable about contraception and abortion techniques, and only need reassurance. Most patients, however, need not only explanation about the abortion procedure, but total information about the various contraceptive methods. Attitude, patience, understanding and sympathy of the counseling personnel are just as important as their professional training.

We studied the fitness and abortion levels in five species of genus Cestrum L. (Solanaceae) present in a cloud forest of Parque Nacional Henri Pittier, Venezuela. The seed set is variable and the abortion is higher at flowers-fruits and ovule levels, while the S/O ratio is low. We discuss the possible causes of abortion and seed set in these species.

Data from the Growth of Alberta Family Study were used to estimate the illegal abortion rate for the residents of Edmonton, Alberta and to assess the potential impact of eliminating therapeutic abortion on the birth rate and on the illegal abortion rate. The study population consisted of 938 women, aged 18-54. The women were divided into 3 groups, and sensitive abortion data was elicited from each group using different data collection techniques. One group was asked about abortion in the traditional interview mode. Another group was asked to mail in their responses to abortion answers anonymously, and the remaining group was questioned about abortion using the (RRT) randomized response technique. The use of the RRT allowed the respondent to answer yes or no questions without the interviewer being aware that the respondent was responding to sensitive abortion questions. The RRT elicited information on a greater number of abortions than the other 2 techniques. According to calculations based on the RRT elicited information, the illegal abortion rate in Edmonton was 22.4/100 conceptions surviving the 1st 4 weeks of gestation. In view of the controversy surrounding the current abortion law, an effort was made to assess the effects of eliminating therapeutic abortions. A method, previously developed by Tietze for calculating the impact of abortion laws on the birth rate in New York, was applied to the Alberta data. The conclusion was reached that if therapeutic abortions were eliminated, the effect on the birth rate would be negligible and the illegal abortion rate would increase by 12%. The estimated illegal abortion rates and other major study results were presented in tabular form.

The timing of ossification of middle ear ossicles has been extensively studied in humans. This is an exception since it is vastly unknown in the +5000 extant species of placentals. As a preliminary approach, a cow foetus (around 115 days of gestation) was visualized using X-ray microtomography (μCT) and the ossicles including stapes, incus, and malleus could be extracted from the data set. All three bones have already undergone substantial ossification, which allow comparison to adult middle ear bones. Their ossification at this stage parallels ossification in humans at a comparable stage of gestation. While full ossification is not yet achieved almost all the morphological characters of the ossicles are observed. Bone tissue is still very porous, the stapes does not have the characteristic plate-like footplate, the lenticular process of the incus is missing and the manubrium of the malleus is very thin and not yet complete. Despite all this, the ossicles are articulate with each other and perfectly with the bony labyrinth. The stapes footplate is positioned on the oval window but is smaller than the latter while it should perfectly fit to transmit sound vibrations to the cochlea. All ossicles, especially the stapes, have not yet reached adult size, while the bony labyrinth already has. This is the first detailed description of a set of middle ear bones in a placental at mid-gestation based on high-resolution μCT. Similarities in ossification timing with humans encourage more work to be done on foetuses to understand if a general rule for placental mammals exists.

This article examines letters sent by members of the general public to the Abortion Law Reform Association (ALRA) in the decade immediately before the 1967 Abortion Act. It shows how a voluntary organisation, in their aim of supporting a specific cause of unclear legality, called forth correspondence from those in need. In detailing the personal predicaments of those facing an unwanted pregnancy, this body of correspondence was readily deployed by ALRA in their efforts to mobilise support for abortion law reform, thus exercising a political function. A close examination of the content of the letters and the epistolary strategies adopted by their writers reveals that as much as they were a lobbying tool for changes in abortion law, these letters were discursively shaped by debates surrounding that very reform.

Introduction The termination of unwanted pregnancies up to 12 weeks’ gestation became legal in Nepal in 2002. Many interventions have taken place to expand access to comprehensive abortion care services. However, comprehensive abortion care services remain out of reach for women in rural and remote areas. This article describes a training and support strategy to train auxiliary nurse‐midwives (ANMs), already certified as skilled birth attendants, as medical abortion providers and expand geographic access to safe abortion care to the community level in Nepal. Methods This was a descriptive program evaluation. Sites and trainees were selected using standardized assessment tools to determine minimum facility requirements and willingness to provide medical abortion after training. Training was evaluated via posttests and observational checklists. Service statistics were collected through the government's facility logbook for safe abortion services (HMIS‐11). Results By the end of June 2014, medical abortion service had been expanded to 25 districts through 463 listed ANMs at 290 listed primary‐level facilities and served 25,187 women. Providers report a high level of confidence in their medical abortion skills and considerable clinical knowledge and capacity in medical abortion. Discussion The Nepali experience demonstrates that safe induced abortion care can be provided by ANMs, even in remote primary‐level health facilities. Post‐training support for providers is critical in helping ANMs handle potential barriers to medical abortion service provision and build lasting capacity in medical abortion. PMID:26860072

Two physicians debate whether abortions should be available on request regardless of medical indications. The crux of the issue is whether the fetus should be considered body tissue over which the woman has complete control or whether society has an interest in the embryo and should protect it.

This paper argues that the central issue in the abortion debate has not changed since 1967 when the English parliament enacted the Abortion Act. That central issue concerns the moral status of the human fetus. The debate here is not, it is argued, primarily a moral debate, but rather a metaphysical debate and/or a theological debate--though one with massive moral implications. It concerns the nature and attributes that an entity requires to have "full moral standing" or "moral inviolability" including a "right to life". It concerns the question when, in its development from newly fertilised ovum to unequivocally mature, autonomous morally inviolable person does a human being acquire that nature and those attributes, and thus a "right to life". The paper briefly reviews standard answers to these questions, outlining some problems associated with each. Finally there is a brief discussion of one way in which the abortion debate has changed since 1967--notably in the increasingly vociferous claim, especially from disability rights sectors, that abortion on grounds of fetal abnormality implies contempt for and rejection of disabled people--a claim that is rebutted.
The paper argues that the women's movement has failed to adequately take account of women with disabilities. By supporting women's right to abortions for handicapped fetuses, the movement denies disabled women an identity as equal human beings worthy of respect. (JDD)

A federal appellate court for Massachusetts has ruled that regulations prohibiting counseling or referrals for abortion services violate the constitutional right to reproductive choice. The regulations in question were promulgated under Title X of the US Public Health Service Act. The regulations required pregnant women to be furnished with a list of providers who supported the welfare of the mother and the fetus, thus making the decision to abort more difficult and intruding upon pre- existing physician-patient relationships. The regulations further imposed substantial costs and delays on women who chose to abort through their endorsement of the withholding of requested information. In finding these regulations unconstitutional, the Court noted that they went beyond a mere refusal to fund abortion and interfered with the decision making process by dictating the information a woman was entitled to receive. On the basis of general principles that govern the provision of health services and the physician-patient relationship, the American Medical Association supported the position that the Title X regulations were unconstitutional. The Association noted in its brief that physicians must be free to reveal to their patients all the relevant facts patients need to make an informed decision about medical treatment, even if the physician does not personally plan to provide such treatment.

In a study of 404 women (simple random sample), 20-29 years of age, 201 (group A) applying for abortion and 203 (group B) continuing their pregnancies, the women were given a questionnaire and in addition were interviewed. The aim of the study was to evaluate the spontaneous personal motives of women for abortion at a time when age is not supposed to be a common reason. The results showed that more than half of the women expressed that a bad relationship with the partner in one way or another was a motive for the abortion. Other important motives included characteristics of the women and their partners, mainly immaturity, work/studies and unsuitable life situation for having a child. Less common motives seemed to be economy, dwelling and medical and health factors. It is obvious that women in this study wanted to have a stable relationship to the child's father before they dared or wanted to have a child. Social networks in modern society seem to be too weak. The women do not want to face social and emotional problems as lonely mothers. Political decisions in the society, for example with parental benefit according to your income discourage women from continuing their pregnancies during their studies. It also seems important for the woman to feel mature enough to have a child. The provision and encouragement of methods for safer sex may be a possible way by which to reduce the number of abortions.

Investigated demographic and psychological factors related to positive or negative reactions to legal abortions performed during the first trimester of pregnancy in 62 females in an urban southern community. Results suggest that the social context and the degree of support from a series of significant persons rather than demographic variables were most predictive of a positive reaction.

Background Spontaneous abortion is the most common adverse pregnancy outcome. We aimed to investigate a possible link between nutrient deficiencies and the risk of spontaneous abortion. Materials and Methods This case-control study included the case group (n=331) experiencing a spontaneous abortion before 14 weeks of pregnancy and the control group (n=331) who were healthy pregnant women over 14 weeks of pregnancy. The participants filled out Food Frequency Questionnaire (FFQ), in which they reported their frequency of consumption for a given serving of each food item during the past three months, on a daily, weekly or monthly basis. The reported frequency for each food item was converted to a daily intake. Then, consumption of nutrients was compared between the two groups. Results There are significant differences between the two groups regarding consumed servings/day of vegetables, bread and cereal, meat, poultry, fish, eggs, beans, fats, oils and dairy products (P=0.012, P<0.001, P=0.004, P<0.001, P=0.019, respectively). There are significant differences between the two groups in all micronutrient including folic acid, iron, vitamin C, vitamin B6, vitamin B12 and zinc (P<0.001). Conclusion Poor nutrientions may be correlated with increased risk of spontaneous abortion. PMID:28042413

Two folk medical conditions, "delayed" (atrasada) and "suspended" (suspendida) menstruation, are described as perceived by poor Brazilian women in Northeast Brazil. Culturally prescribed methods to "regulate" these conditions and provoke menstrual bleeding are also described, including ingesting herbal remedies, patent drugs, and modern pharmaceuticals. The ingestion of such self-administered remedies is facilitated by the cognitive ambiguity, euphemisms, folklore, etc., which surround conception and gestation. The authors argue that the ethnomedical conditions of "delayed" and "suspended" menstruation and subsequent menstrual regulation are part of the "hidden reproductive transcript" of poor and powerless Brazilian women. Through popular culture, they voice their collective dissent to the official, public opinion about the illegality and immorality of induced abortion and the chronic lack of family planning services in Northeast Brazil. While many health professionals consider women's explanations of menstrual regulation as a "cover-up" for self-induced abortions, such popular justifications may represent either an unconscious or artful manipulation of hegemonic, anti-abortion ideology expressed in prudent, unobtrusive and veiled ways. The development of safer abortion alternatives should consider women's hidden reproductive transcripts.
A brief study was carried out to determine the feasibility of a special kicker to produce a damped spiral beam at the beam dump for the beam abort system. There appears to be no problem with realizing this concept at a reasonably low cost.

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.
A new publication of the World Health Organization, "Abortion in the Developing World," reports that 40% of the 50 million abortions performed each year are unsafe, and 90% of these medically perilous procedures occur in developing countries. Although the 30 million abortions performed annually in developing countries represent 60% of the global total, they account for 95% of abortion-related deaths. Abortion was illegal in 94% of the developing countries included in the WHO study. Unexpectedly, the proportion of women who were using contraception when they experienced an unintended pregnancy was similar in countries with strong family planning programs and those with weak or nonexistent programs.
Misoprostol, a WHO essential medicine indicated for labour induction, management of miscarriage and post-partum haemorrhage, as well as for induced abortion and treatment of post-abortion complications, came up for registration in Sri Lanka in December 2010. The decision on registration was postponed, indefinitely. This has wide-ranging implications, as misoprostol is widely available and used, including by health professionals in Sri Lanka, without guidance or training in its use. This paper attempts to situate the failure to register misoprostol within the broader context of unsafe abortion, drawing on data from interviews with physicians and health policymakers in Sri Lanka. It demonstrates how personal opposition to abortion infiltrates policy decisions and prevents the issue of unsafe abortion being resolved. Any move to reform abortion law and policy in Sri Lanka will require a concerted effort, spearheaded by civil society. Women and communities affected by the consequences of unsafe abortion need to be involved in these efforts. Regardless of the law, women will access abortion services if they need them, and providers will provide them. Decriminalizing abortion and registering abortion medications will make provision of abortion services safer, less expensive and more equitable.

Targeted Regulations of Abortion Providers (TRAP laws) are proliferating in the United States and have increased barriers to abortion access. In order to comply with these laws, abortion providers make significant changes to facilities and clinical practices. In this article, we draw attention to an often unacknowledged area of public health threat: how providers adapt to increasing regulation, and the resultant strains on the abortion provider workforce. Current US legal standards for abortion regulations have led to an increase in laws that target abortion providers. We describe recent research with abortion providers in North Carolina to illustrate how providers adapt to new regulations, and how compliance with regulation leads to increased workload and increased financial and emotional burdens on providers. We use the concept of invisible labor to highlight the critical work undertaken by abortion providers not only to comply with regulations, but also to minimize the burden that new laws impose on patients. This labor provides a crucial bridge in the preservation of abortion access. The impact of TRAP laws on abortion providers should be included in the consideration of the public health impact of abortion laws. PMID:27570376

Small island exigencies and a legacy of colonial jurisprudence set the stage for this three-year study in 2001-2003 of abortion practice on several islands of the northeast Caribbean: St. Martin, St. Maarten, Anguilla, Antigua and St Kitts. Based on in-depth interviews with 26 physicians, 16 of whom were performing abortions, it found that licensed physicians are routinely providing abortions in contravention of the law, and that those services, tolerated by governments and legitimised by European norms, are clearly the mainstay of abortion care on these islands. Medical abortion was being used both under medical supervision and through self-medication. Women travelled to find anonymous services, and also to access a particular method, provider or facility. Sometimes they settled for a less acceptable method if they could not afford a more comfortable one. Significantly, legality was not the main determinant of choice. Most abortion providers accepted the current situation as satisfactory. However, our findings suggest that restrictive laws were hindering access to services and compromising quality of care. Whereas doctors may have the liberty and knowledge to practise illegal abortions, women have no legal right to these services. Interviews suggest that an increasing number of women are self-inducing misoprostol abortions to avoid doctors, high fees and public stigma. The Caribbean Initiative on Abortion and Contraception is organising meetings, training providers and creating a public forum to advocate decriminalisation of abortion and enhance abortion care.
A post-independence (1992-93) decree issued by the Estonian Ministry of Social Affairs permits abortion on request up to 12 weeks of gestation and, on medical grounds, up to 20 weeks. According to reports received by the Estonian Medical Statistical Bureau, the 1994 abortion rate was 53.8/1000 women of reproductive age. Among women under 20 years of age, the abortion rate declined from 55.5/1000 in 1992 to 41.5/1000 in 1994. Only mini-abortions and abortions performed for medical reasons are free of charge; women with health insurance pay 50% of the cost of most procedures. Funds from abortion fees are used to subsidize contraception for full-time students, women in the first postpartum year, and women who had an induced abortion in the past three months. All other women must pay the full price of contraception. In 1994, only 234 out of every 1000 fertile women were using effective forms of contraception (IUDs and hormonal methods). However, the birth rate has been declining rapidly since 1990 and the rate of natural increase became negative in 1993 (-4.0). The fact that abortion but not contraception is subsidized has facilitated reliance on abortion as a family planning method. Recommended, to reduce the abortion rate and improve the family planning situation in Estonia, are improved contraceptive counseling, including pre- and post-abortion services, and school-based sex education.

Bovine postpartum uterine disease, metritis, affects about 40% of animals and is widely considered to have a bacterial aetiology. Although the gamma-herpesvirus bovine herpesvirus 4 (BoHV-4) has been isolated from several outbreaks of metritis or abortion, the role of viruses in endometrial pathology and the mechanisms of viral infection of uterine cells are often ignored. The objectives of the present study were to explore the interaction, tropism and outcomes of BoHV-4 challenge of endometrial stromal and epithelial cells. Endometrial stromal and epithelial cells were purified and infected with a recombinant BoHV-4 carrying an enhanced green fluorescent protein (EGFP) expression cassette to monitor the establishment of infection. BoHV-4 efficiently infected both stromal and epithelial cells, causing a strong non-apoptotic cytopathic effect, associated with robust viral replication. The crucial step for the BoHV-4 endometriotropism appeared to be after viral entry as there was enhanced transactivation of the BoHV-4 immediate early 2 gene promoter following transient transfection into the endometrial cells. Infection with BoHV-4 increased cyclooxygenase 2 protein expression and prostaglandin estradiol secretion in endometrial stromal cells, but not epithelial cells. Bovine macrophages are persistently infected with BoHV-4, and co-culture with endometrial stromal cells reactivated BoHV-4 replication in the persistently infected macrophages, suggesting a symbiotic relationship between the cells and virus. In conclusion, the present study provides evidence of cellular and molecular mechanisms, supporting the concept that BoHV-4 is a pathogen associated with uterine disease.

Abortion remains a highly contentious moral issue, with the debate usually framed as a battle between the fetus's right to life and the woman's right to choose. Often overlooked in this debate is the impact of the concurrent legalization of abortion and the development of new prenatal screening tests on the birth prevalence of many inherited diseases. Most proponents of abortion support abortion for fetuses with severe congenital diseases, but there has unfortunately been, in our opinion, too little debate over the moral appropriateness of abortion for much less severe congenital conditions such as Down's syndrome, deafness, and dwarfism. Due to scientific advances, we are looking at a future in which prenatal diagnosis will be safer and more accurate, raising the specter, and the concomitant ethical concerns, of wholesale abortions. Herein, we present a reframing of the abortion debate that better encompasses these conditions and offers a more nuanced position.

In England, Scotland and Wales legislation has facilitated the process of procuring an abortion to the point at which, in 2007, it appears to have been effectively assimilated into contemporary life. However, despite the legal acceptance of abortion it remains an ethically contentious subject. Arguments in favour of, or in opposition to, abortion can arouse vociferous and, on occasions, extreme reactions. At the heart of the abortion debate lie questions concerning rights, autonomy and the way in which society views disability (if a pregnancy is terminated for this reason alone). It is important that health professionals comprehend the basis of the abortion debate, from the perspective of their profession, society as a whole and the individual woman who may have had or is considering an abortion or has been affected by the subject in some way. This article examines some of the key ethical issues concerning abortion.

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.

Salmonella enterica subspecies enterica Indiana, a food-borne serovar uncommon in most countries, was responsible for an outbreak of abortion in a flock of Lacaune dairy ewes in southern Spain. Drinking water and feedstuff samples were analysed in an attempt to determine the source of the infection. Pigeons (Columba livia) and turtledoves (Streptopelia turtur) in close contact with the ewes were captured and examined for the bacterium. Seventeen S. Indiana strains were isolated from the ewes and wild birds and the genetic similarity among them analysed by Pulsed Field Gel Electrophoresis (PFGE) after the digestion of their genomic DNA with the restriction enzyme XbaI. The results suggest the wild birds might be responsible for the outbreak in the ewes. The strains recovered were fully susceptible to 15 out of the 16 antimicrobial agents tested: ampicillin, amoxycillin clavulanate, cephalothin, ceftriaxone, gentamicin, neomycin, streptomycin, tetracycline, ciprofloxacin, enrofloxacin, sulphonamides, trimethoprim-sulphamethoxazole, apramycin, colistin and chloramphenicol. Differences in the resistance pattern to nalidixic acid were observed; 11 strains (64.7%) were nalidixic acid resistant (R-Nx) and 6 (35.3%) sensitive (S-Nx). Among the R-Nx strains, a substitution of Gly to Cys at position 81 (Gly81àCys) of the gyrA gene in 10 strains isolated from wild birds and ovine foetuses, and of Asp to Tyr at position 87 (Asp87àTyr) in one strain isolated from ewe faeces, were revealed by sequencing the gene. To control the outbreak, enrofloxacin treatment was administered for 5 days. The same therapy was used to prevent infection during following gestation cycles, administering the antimicrobial agent at presentation and over 4 weeks before birth. Anti-bird meshes and closed drinking and feeding troughs were also installed to prevent further contact of the ewes with wild birds.

OBJECTIVE--To investigate the incidence of spontaneous abortion in a population of women in order to establish their risk of spontaneous abortion and the obstetric factors predisposing to it. DESIGN--Prospective study of women recruited by radio and poster appeal and from hospital outpatient clinics. SETTING--English provincial community. PATIENTS--630 Women from the general population intending to become pregnant. INTERVENTIONS--The viability of the pregnancy was assessed by abdominal ultrasonography before completion of the eighth week, and the assessment was repeated if vaginal bleeding occurred. MAIN OUTCOME MEASURE--Spontaneous abortion or live births in women with or without a previous history of spontaneous abortion. RESULTS--The overall incidence of clinically recognisable spontaneous abortion before 20 weeks of gestation was 12% (50/407 pregnancies). The risk of spontaneous abortion in each category of patient was classified with respect to the patient's past reproductive performance and found to be influenced greatly by her previous obstetric history. In primigravidas and women with a history of consistently successful pregnancies the incidences of abortion were low (5% (4/87) and 4% (3/73) respectively), whereas women with only unsuccessful histories had a much greater risk of aborting the study pregnancy (24% (24/98)), even when their sole pregnancy had ended in abortion (20% (12/59)). The outcome of the last pregnancy also influenced the outcome of the study pregnancy; only 5% of women (5/95) whose previous pregnancy had been successful aborted, whereas the incidence of loss of pregnancy among women whose last pregnancy had aborted was 19% (40/214). CONCLUSIONS--A knowledge of the patient's reproductive history is essential for the clinical assessment of her risk of spontaneous abortion. As the most important predictive factor for spontaneous abortion is a previous abortion, the outcome of a woman's first pregnancy has profound consequences for all

Foot-and-mouth disease (FMD) is a highly contagious and economically important viral disease of cloven-hoofed animals, including domestic and wild host species. During recent FMD outbreaks in India, spontaneous abortions were reported amongst FMD-affected and asymptomatic cows. The current study was an opportunistic investigation of these naturally occurring bovine abortions to assess causality of abortion and vertical transmission of FMDV from infected cows to fetuses. For this purpose, fetal tissue samples of eight abortuses (heart, liver, kidney, spleen, palatine tonsil, umbilical cord, soft palate, tongue, lungs, and submandibular lymph node) were collected and screened by various detection methods, including viral genome detection, virus isolation, and immunomicroscopy. Amongst these cases, gross pathological changes were observed in 3 abortuses. Gross pathological findings included blood-tinged peritoneal and pleural effusions and myocarditis. Hearts of infected calves had mild to moderate degeneration and necrosis of the myocardium with moderate infiltration by mixed inflammatory cells. Localization of FMDV antigen was demonstrated in lungs and soft palate by immunomicroscopy. FMDV serotype O viral genome was recovered from 7 of 8 cases. Infectious FMDV serotype O was rescued by chemical transfection of the total RNA extracted from three soft palate samples and was sequenced to confirm 100% identity of the VP1 (capsid) coding region with isolates collected from infected cattle during the acute phase of infection. Based upon these findings, it may be concluded that FMDV-associated abortion occurred among the infected pregnant cows included within this study and FMDV was subsequently transmitted vertically to fetuses. This is the first documentation of FMDV-associated abortions in cattle. PMID:27977708

Abortion continues to be a major public health issue that evokes social, political, legal, cultural and religious sentiments and debates in all societies. This is particularly so in countries with restrictive abortion laws. It is one of the leading causes of maternal mortality and morbidity. Despite variations in the legal status of abortions in favor of restrictiveness in developing countries compared with developed countries, overall rates are quite higher in the developing countries. This review article therefore, examines the historical perspectives of induced abortion as well as the issues and controversies associated with induced abortion. Also, a review of the Nigeria national abortion law is made. We believe that this is capable of identifying useful interventions for designing programs that will lead to a reduction in the burden of unsafe abortion in developing countries.

A survey was carried out on 23 sheep flocks to estimate the frequency of abortion as well as the prevalence of antibodies against abortive infections. During the visit of each farm, a questionnaire was completed with the collaboration of the owner and blood samples were collected from all aborted ewes and some of those with normal lambing. A rate of 7% abortion was reached in both aborted and normally lambed ewes. Anti-Chlamydia psittaci antibodies were the most frequently detected (14 flocks). Anti-Coxiella burnetii and anti-Toxoplasma gondii antibodies were found in 9 flocks, whereas anti-Brucella and anti-Salmonella abortus ovis were present in only 1 flock each. None of the 5 infections was detected in 2 flocks. Mixed infections were prevalent: 13 flocks were simultaneously infected by at least 2 abortive pathogens. The procedure used does not allow the cause of abortion to be identified in all cases.

In 1993, noncytopathic bovine viral diarrhea virus (BVDV) strains with enhanced virulence caused unprecedented outbreaks of severe acute bovine viral diarrhea (BVD) in dairy, beef, and veal herds in Ontario (Canada). Fever, pneumonia, diarrhea, and sudden death occurred in all age groups of cattle. Abortions often occurred in pregnant animals. Gross lesions in the alimentary tract were similar to those associated with mucosal disease, especially in animals >6 months of age. Cattle of all age groups had microscopic lesions in the alimentary tract similar to those seen with mucosal disease. The epidemic peaked in the summer of 1993, with 15% of all bovine accessions from diseased cattle presented to the diagnostic laboratory being associated with BVDV. The virus strains involved in the outbreak were analyzed using monoclonal and polyclonal antibodies and the polymerase chain reaction. The virus isolates from these outbreaks of severe disease were determined to be type 2 BVDV. Type 2 BVDV has been present in Ontario at least since 1981 without causing widespread outbreaks of severe acute BVD, which suggests that type 2 designation in itself does not imply enhanced virulence. Cattle properly vaccinated with type 1 BVDV vaccines appear to be protected from clinical disease.

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. In biblical
The 1995 US abortion rate of 20/1000 women of reproductive age was the lowest recorded since 1975. In the period 1994-95, the birth rate decreased 1.5%, and the abortion rate decreased 4.5%. Part of the explanation for this decline can be found in the demographic make-up of US women of reproductive age. The number of women in this group has grown since 1980, but the percentage in the most fertile younger age group has declined while that in the less fertile older age group grew. The decline in births and abortions is also due to increased contraceptive usage, especially among adolescents responding to the HIV/AIDS threat. The drop in the abortion rate may also be due to the use of Norplant by adolescents who had given birth and wanted to avoid another birth. Adolescents accounted for 26% of abortions in 1985 and only 20% in 1995. More abortions are being provided at high-volume clinics, and the number of small abortion providers is decreasing. High volume clinics are associated with low complication rates, but women may have to travel further to avail themselves of abortion services. Only 12% of family practice programs nationwide offer abortion training to their residents, and this may contribute to a shortage of abortion providers.

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.

Nothing in the field of health care generates more controversy than does the issue of abortion. The views of 396 undergraduates of Obafemi Awolowo University, Ile-Ife, Nigeria concerning the liberalisation of abortion laws were investigated in May 2001. Ninety respondents (22.7%) supported the liberalisation of abortion laws in Nigeria because they believed that it would lead to reduction in associated morbidity and mortality, encourage more qualified personnel to perform it, encourage women to request abortion openly and encourage accurate statistics on abortion. However, the majority of the respondents (59.6%) opposed the liberalisation of abortion laws due to the fear that it would increase promiscuity, sexually transmitted diseases and abortion rates. Religious opposition and the belief that liberalisation would not reduce the level of poverty, ignorance and poor reproductive health facilities were the common factors leading to unwanted pregnancy and unsafe abortion in Nigeria. Support for the liberalisation of abortion laws shows significant relationship with increasing age (P = 0.001), male sex (P = 0.001) and a science-orientated faculty (P<0.05), but not religion. There is every indication that the issue of abortion is one that will continue to be unresolved for the forseeable future.

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

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.

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.

On February 2, 1975 the Federal Constitutional Court gave the indications for abortion. But the regulations are often misunderstood and are often contravened by mistake. Hence the following explanations are for the assistance of physicians. The sections discussed are sec. 218 (abortion), 218a (indications for abortion), 218b (abortion without advising the woman), 219 (abortion without a physician's order), 219a (wrongful physician's order), 219b (soliciting abortion), 219c (transporting the instruments used for abortion), and 219d (definition). The law recognizes only medical indications for abortion: the purely medical indication, the indication of damage to the fetus, the criminological indication, and the indication from extreme emergency. The law states clearly that no one is compelled to perform an abortion, whatever the consequences for the mother and fetus might be. The law provides for stages of notification: 1) the personal physician must provide in writing a well-grounded indication for abortion; 2) in the absence of a purely medical indication, the woman must at least 3 days before rupture request assistance from a social service agency or a physician with appropriate knowledge and skill; 3) the woman must have explained to her all aspects of abortion, not only the purely medical, but also the arguments of various kinds against it; and 4) the physician who undertakes to do the abortion is responsible for ensuring that all provisions of the law have been satisfied. The law provides that abortion may be done only in a hospital, i.e., a place where special arrangements for it may be made; it cannot be done on an outpatient basis.

Four decades after Roe v. Wade, abortion remains highly contentious, pitting a woman's right to choose against a fetal claim to life. Public health implications are staggering: the US annual total of more than one million induced abortions equals nearly half the number of registered deaths from all causes. Sentiment regarding abortion is roughly evenly split among the general public, yet fundamental debate about abortion is largely absent in the public health community, which is predominantly supportive of its wide availability. Absence of substantive debate on abortion separates the public health community from the public we serve, jeopardizing the trust placed in us. Traditional public health values—support for vulnerable groups and opposition to the politicization of science—together with the principle of reciprocity weigh against abortion. Were aborted lives counted as are other human lives, induced abortion would be acknowledged as the largest single preventable cause of loss of human life. Lay Summary: Four decades after Roe v. Wade, abortion remains highly divisive. Public sentiment regarding abortion is roughly evenly split, yet fundamental debate is largely absent in the public health community, which supports abortion’s wide availability. Absence of substantive debate separates the public health community from the public it serves. Traditional public health values—support for vulnerable populations and opposition to politicization of science—and the principle of reciprocity (“the Golden Rule”) weigh against abortion. Were aborted lives counted as are other human lives, induced abortion would be acknowledged as the largest single preventable cause of loss of human life. PMID:27833179
Legislators or regulators in Mississippi, South Carolina, and Missouri have imposed burdensome and unnecessary clinic requirements on abortion providers. In each case, the legislators or regulators designed the requirements to make abortions more difficult to obtain. Mississippi, a state with only two licensed abortion clinics, already had restrictive abortion laws. In August 1996, it implemented stringent regulations on private physicians who provide abortion services in their offices. Some requirements include purchasing specific equipment, widening hallways, and hiring more staff. Several physicians have filed a lawsuit to stop enforcement of the regulations because they make the provision of abortion services so cumbersome and expensive as to discourage physicians from offering abortions. Antiabortion groups testified before the legislature that the Department of Health had been negligent in monitoring private practices for compliance with Mississippi's many abortion laws, particularly counseling requirements. The Republican governor signed the legislation in March 1996. In July 1996, a federal judge prohibited the South Carolina Department of Health from enforcing a new regulation making physicians who perform as few as five abortions a month to meet strict specifications for their office (e.g., disclosure of patient records and medical agreements). The regulation was a response to a 1995 law targeting private physicians who perform abortions in their offices. The judge held that the substantial changes in terms of privacy and expense could bring an undue burden on women seeking abortions. The state denied that the regulation would close clinics or would increase costs so much as to make abortions inaccessible. In September 1996, the House did not override the Democratic governor's veto of a bill that would have required all facilities where abortions are done to be licensed and undergo annual inspections and that would have required all physicians to have

While laws in Uganda surrounding abortion remain contradictory, a frequent interpretation of the law is that abortion is only allowed to save the woman's life. Nevertheless abortion occurs frequently under unsafe conditions at a rate of 54 abortions per 1000 women of reproductive age annually, taking a large toll on women's health. There are an estimated 148,500 women in Uganda who experience abortion complications annually. Understanding opinion leaders' knowledge and perceptions about unsafe abortion is critical to identifying ways to address this public health issue. We conducted in-depth, semi-structured interviews with 41 policy-makers, cultural leaders, local politicians and leaders within the health care sector in 2009-10 at the national as well as district (Bushenyi, Kamuli and Lira) level to explore their knowledge and perceptions of unsafe abortion and the potential for policy to address this issue. Only half of the sample knew the current law regulating abortion in Uganda. Respondents understood that the result of the current abortion restrictions included long-term health complications, unwanted children and maternal death. Perceived consequences of increasing access to safe abortion included improved health as well as overuse of abortion, marital conflict and less reliance on preventive behaviour. Opinion leaders expressed the most support for legalization of abortion in cases of rape when the perpetrator was unknown. Understanding opinion leaders' perspectives on this politically sensitive topic provides insight into the policy context of abortion laws, drivers behind maintaining the status quo, and ways to improve provision under the law: increase education among providers and opinion leaders.

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

The effects of enalapril, an angiotensin converting enzyme (ACE) inhibitor, on maternal and foetal blood pressure, heart rate and components of the renin-angiotensin-aldosterone system were studied in 9 chronically-cannulated pregnant ewes and their foetuses. Six ewes received 1 mg kg-1 enalapril i.v. while 3 were given 2 mg kg-1. Although the initial fall in blood pressure was slightly greater in the higher dose group, there was substantial overlap of data. The pressor response to angiotensin I, assessing ACE activity, was abolished within 10 min of administration, and did not recover during 3 h of observation. Maternal systolic and diastolic pressures reached a nadir 90 min after administration (P less than 0.001, P less than 0.002 respectively). The maximum tachycardia was seen at 60 min (P less than 0.05). The foetuses of the ewes given 1 mg kg-1 enalapril showed no change in systolic or diastolic blood pressure or heart rate. Those of the ewes given the higher dose showed late-onset hypotension, coincident with the lowest maternal blood pressures. Maternal plasma renin concentration (PRC) had risen significantly by 30 min (P less than 0.02), reaching a maximum at approximately 90 min. Maternal plasma angiotensin II and aldosterone concentrations both fell initially (P less than 0.05) but were almost at basal levels by the end of the experiment. Foetal plasma renin, angiotensin II and aldosterone concentrations were unchanged throughout the experiment. Peak values of enaprilic acid, the active principle, were recorded in maternal plasma 65-90 min after administration of 1 mg kg-1, and 25-30 min after the administration of 2 mg kg-1. A trace amount of the active principle was recorded in the foetal plasma of one lamb, whose mother had been given the higher dose. None was recorded in the plasma from three other lambs. Maternal plasma ACE concentrations fell by an average of 84%; in 4 of the 6 ewes in which concentrations were measured they were undetectable after
