Abstract
Listeria monocytogenes, a gram-positive bacillus and an intracellular pathogen, is an uncommon cause of illness in the general population. During pregnancy, a perinatal infection can lead to serious complications such as abortion, stillbirth, neonatal sepsis, and meningitis. We present two cases of neonatal meningitis caused by Christie, Atkins, Munch-Peterson (CAMP)-negative Listeria monocytogenes. In the first case, a seven-day-old female term neonate delivered vaginally, presented with high-grade fever and refusal to feed. In view of the suspected late-onset sepsis, a septic workup, including cerebrospinal fluid analysis, was conducted. CSF culture reports obtained showed a growth consistent with Listeria monocytogenes, which was CAMP test negative and susceptible to the penicillin group of drugs, cotrimoxazole, erythromycin, and meropenem. The isolate was identified using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and confirmed by 16S rRNA sequencing. The blood culture was sterile. At 48 hours of admission, the neonate clinically deteriorated with fluctuation in oxygen saturation below 95% at room air. Thus, she was electively intubated and connected to the mechanical ventilator with appropriate settings. The antibiotics were upgraded to meropenem from the empirical antibiotic therapy. The neonate showed clinical improvement within the next 24 hours of initiating antibiotics according to culture susceptibility and was gradually weaned from the mechanical ventilator to continuous positive airway pressure (CPAP). After 24 hours, she was able to maintain normal saturation at room air. In the second case, an 11-day-old low birth weight neonate, small for gestational age, was presented to the NICU with complaints of loose stools, fever, and refusal to feed for the past two days. In view of the suspected sepsis, relevant investigations were carried out while initiating empirical antibiotics IV piperacillin-tazobactam and IV amikacin for the neonate. Meanwhile, there was a dip in oxygen saturation noted on room air for the neonate and he/she was mechanically ventilated. The CSF culture grew Listeria monocytogenes,which was identified using MALDI-TOF MS and confirmed by 16S rRNA sequencing. The isolate tested negative for the CAMP test and was susceptible to ampicillin, penicillin, cotrimoxazole, erythromycin, and meropenem. The blood culture was sterile. The antibiotics were upgraded to meropenem from the empirical antibiotic therapy, the patient's condition improved, and the baby was eventually discharged.

Abstract
Abortion policy is conventionally viewed as a political matter with religious overtones. This article offers a different view. From the perspective of evolutionary biology, abortion at a young age can represent prioritization of long-term development over immediate reproduction, a pattern established in other animal species as resulting from stable ecologies with low mortality risk. We examine whether laws and moral beliefs about abortions are linked to local mortality rates. Data from 50 U.S. states, 202 world societies, 2,596 adult individuals in 363 U.S. counties, and 147,260 respondents across the globe suggest that lower levels of mortality risk are associated with more permissive laws and attitudes toward abortion. Those associations were observed when we controlled for religiosity, political ideology, wealth, education, and industrialization. Integrating evolutionary and cultural perspectives offers an explanation as to why moral beliefs and legal norms about reproduction may be sensitive to levels of ecological adversity.

Abstract
INTRODUCTION The administration of mifepristone, followed by misoprostol, is widely used for medical abortion. Many studies have demonstrated home abortion to be safe in pregnancies up to 63 days of gestation, and recent data support its safety when extended to more advanced pregnancies. We studied the efficacy and acceptability of home use of misoprostol up to 70 days of gestation in a Swedish setting and compared the outcomes between pregnancies with a gestational age of up to 63 days and pregnancies with gestational age 64-70 days. MATERIAL AND METHODS This prospective cohort study was performed between November 2014 and November 2021 at Södersjukhuset and Karolinska University Hospital, Stockholm, and some patients were also recruited from Sahlgrenska University Hospital, Göteborg and Helsingborg Hospital. The primary outcome was the rate of complete abortions and was defined as complete abortion without any need for surgical or medical intervention and assessed by clinical assessment, pregnancy test and/or vaginal ultrasound. Secondary objectives were assessed by daily self-reporting in a diary and included pain, bleeding, side effects and women's satisfaction and perception of home use of misoprostol. A comparison of categorical variables was made with Fisher's exact test. The significance level was set to a p-value ≤0.05. The study was registered at Clinicaltrials.gov on July 14, 2014 (NCT02191774). RESULTS During the study period we enrolled 273 women opting for medical abortion with home use of misoprostol. In the early group, up to 63 days of gestation, 112 women were included with a mean gestational length of 45 days and in the late group, 64-70 days of gestation, 161 women with a mean gestations length of 66.3 days were included. Complete abortion occurred in 95% (95% CI 89-98) of women in the early group and in 96% (95% CI 92-99) in the late group. No differences were found regarding side effects and acceptability was similarly high in both groups. CONCLUSIONS Our results show high efficacy and acceptability of medical abortion when misoprostol is administered at home up to 70 days of gestation. This supports previous findings about maintained safety when misoprostol is administered at home even past a very early pregnancy.

Abstract
Equine piroplasmosis (EP) is a vector borne disease caused by apicomplexans protists Babesia caballi (Nuttal et Strickland, 1910) and Theileria equi (Laveran, 1901). Carrier mares may transmit the infection transplacental resulting in neonatal piroplasmosis or abortions. This event has been described for T. equi by several authors over the world, but no evidence for B. caballi has been reported in Europe. In this study, vertical transmission for both parasites in an Italian breed mare has been confirmed using molecular and microscopic tools. Transplacental transmission is an underestimated problem mainly in endemic areas as it not only contributes to the spread and maintenance of the infection, but also produces significant economic losses.

Abstract
Intrauterine adhesions are a serious complication that occurs after intrauterine procedures, most often in connection with pregnancy. Manifestations such as amenorrhea, pelvic pain, and infertility for a woman, especially in reproductive age, are serious and together with intrauterine adhesions we call them Asherman's syndrome. Primary prevention after intrauterine procedures is important. Published studies show that the use of hyaluronic acid gel, especially after abortions, leads to the prevention of moderate and severe intrauterine adhesions and also increases the pregnancy rate.

Abstract
Background In low-and middle-income countries, no conclusive research explains the prevalence and associated factors of women with a history of recurrent pregnancy loss (RPL). Some authorities have recommended further scientific research on the effect of various definitions of RPL. Objective To assess prevalence and associated factors of RPL among pregnant women in Nigeria according to different national and international criteria: the American Society for Reproductive Medicine/ European Society for Human Reproduction and Embryology (ASRM/ESHRE; two losses) and the World Health Organization/ Royal College of Obstetricians and Gynecologists (WHO/RCOG; three consecutive losses) criteria. Methods This is a cross-sectional analytical study wherein, pregnant women with prior RPL were investigated. The outcome measures were prevalence and risk factors. The associations between independent variables and outcome variable were explored using bivariate and multivariable logistic regression models. The results of these analyses were reported as adjusted odds ratios (AORs) with 95% confidence intervals (95%CI). Factors associated with RPL were identified using multivariate regression models. Result Of the 378 pregnant women interviewed, the overall prevalence of RPL in this study was found to be 15.34% (95% confidence interval = 11.65%-19.84%). The prevalence of RPL was 15.34% (58/378; 95%CI = 11.65%-19.84%) and 5.29% (20/378; 95%CI = 3.23%-8.17) according to the ASRM and the WHO criterion respectively. Regardless of diagnostic criteria, unexplained (AOR = 23.04; 95%CI: 11.46-36.32), endocrine disturbances (AOR = 9.76; 95%CI: 1.61-63.19), uterine abnormalities (AOR = 13.57; 95%CI: 3.54-50.60), and antiphospholipid syndrome (AOR = 24.59; 95%CI: 8.45-71.04) were positively and independently associated with RPL. No significant risk factors were seen when the ASRM/ ESHRE criterion vs. WHO/RCOG criterion were compared. Advanced maternal age was significantly higher in secondary than in primary type of RPL. Conclusion The prevalence of RPL was 15.34% and 5.29% according to ASRM/ESHRE and WHO/RCOG criterion respectively, with secondary type predominating. No significant differences with regard to risk factors were seen according to diagnostic criteria studied, though advanced maternal age was significantly higher in secondary RPL. Further research is needed to confirm our findings and to better characterize the magnitude of differences.

Abstract
Previous studies on the number of births and the health of the elderly have been highly focused on physical health and used samples from developed countries. Therefore, this study aimed to explore the effect of the lifetime number of births on depression in Chinese older adults. We used panel data for men and women aged 50 and over from the 2013-2018 China Health and Retirement Longitudinal Study. Depressive symptoms were assessed through a short form of the Center for Epidemiologic Studies Depression Scale. We found that depression levels in women were significantly higher than in men, with a mean difference of 2.44 (p < 0.001). The model estimation results indicated that the number of births affected depression in older adults, and its increase could exacerbate depression in older adults. The number of births significantly impacted depression among the elderly aged 50-69. Furthermore, there was a negative relationship between the proportion of sons and older adults' depression, which was significant in older males; the number of abortions may exacerbate depression in older adults, especially in females.

Abstract
Background: This study examined the association between Medicaid expansions under the Affordable Care Act (ACA) and births among low-income women of reproductive age in the United States. Methods: We used data from the 2008 to 2019 American Community Survey to estimate the association between state adoption of Medicaid expansion under the ACA and the percent of low-income women of reproductive age with a birth in the past year using a difference-in-difference research design. Subgroup analysis was explored by race and ethnicity, age group, educational attainment, marital status, and number of children. Results: We found that Medicaid expansion was associated with a small reduction in births among low-income women of reproductive age by 0.45 percentage points (95% confidence interval: -0.84 to -0.05). In subgroup analyses, we found reductions in births among Hispanic women, American Indian or Alaska Native women, women 25-29 years of age, women 35-39 years of age, unmarried women, and women with more than three children. Conclusions: Reductions in births associated with Medicaid expansion could suggest that expanding Medicaid addressed previously unmet reproductive health care needs among low-income women of reproductive age. The reductions in births among low-income women that we observe were occurring among some groups with higher unintended pregnancy rates, including Hispanic women, American Indian or Alaska Native women, young women, and unmarried women. These findings underscore the importance of reproductive health care access through insurance coverage on empowering women to have control over their reproductive decision-making and timing.

Abstract
There are a plethora of publications on the role of miRNA gene polymorphism and its association with recurrent pregnancy loss (RPL), but a lack of uniformity in the studies available due to the variable subject population, heterogeneity and contrary results of significance. Rigorous data mining was done through PubMed, SCOPUS, Cochrane library, Elsevier and Google Scholar to extract the studies of interest published until June 2021. A total of eight SNPs of miRNAs have been included, where ≥2 studies per SNPs were available. Analysis was done on the basis of pooled odds ratios and 95% CI. This is the first meta-analysis on miRNA SNPs in RPL that suggests that rs11614913, rs3746444 and rs2292832 biomarkers may decrease the risk of RPL under different genetic models.

Abstract
Background Miscarriage is a common complication of early pregnancy, mostly occurring in the first trimester. However, the etiological factors and prognostic and diagnostic biomarkers are not well known. Neurokinin-1 receptor (NK-1R) is a receptor of tachykinin peptide substance P (SP) and has a role in various pathological conditions, cancers, but its association with miscarriages and significance as a clinicopathological parameter are not studied. Accordingly, the present study aimed to clarify the localization and expression for NK-1R in human retained products of conception (POC). The role of NK-1R is not known in miscarriages. Materials and Methods NK-1R expression was assessed in POC and normal placental tissues by immunohistochemistry. Three- to four-micrometer-thin sections of formalin-fixed paraffin-embedded tissues were used for this purpose. Tissues were processed and then immunohistochemically stained with NK-1R antibody. Brain tissue was used as control for antibody. Protein expression was evaluated using the nuclear labeling index (%). Tissues were counterstained with 3,3'-diaminobenzidine (DAB), and microscopy was performed at 10×, 20×, and 40× magnifications. Results Ten human POC tissues and 10 normal placental tissues were studied by immunohistochemistry to demonstrate the localization of NK-1R. The expression of NK-1R protein was high in all the cases of both groups. NK-1R expression showed no notable differences among different cases of miscarriages as well as normal deliveries at full term regardless of the mother's age and gestational age at which the event occurred. Statistically, no difference was found in both groups, which is in agreement with our hypothesis and previous findings. Conclusion The expression of NK-1R was similar in all the cases, and it was intense. It shows that dysregulation of NK-1R along with its ligand SP might be involved in miscarriages and also involved in normal delivery. Our results provide fundamental data regarding this anti-NK-1R strategy. Thus, the present study recommends that SP/NK-1R system might, therefore, be considered as an emerging and promising diagnostic and therapeutic strategy against miscarriages. Hence, we report for the first time the expression and localization of NK-1R in POC. We suggest NK-1R antagonist in addition to the immunoglobulins and human chorionic gonadotropin to diagnose and treat spontaneous miscarriages.

Abstract
(1) Background: Rift Valley fever (RVF) outbreaks in domestic ruminants have severe socio-economic impacts. Climate-based continental predictions providing early warnings to regions at risk for RVF outbreaks are not of a high enough resolution for ruminant owners to assess their individual risk. (2) Methods: We analyzed risk factors for RVF occurrence and severity at the farm level using the number of domestic ruminant deaths and abortions reported by farmers in central South Africa during the 2010 RVF outbreaks using a Bayesian multinomial hurdle framework. (3) Results: We found strong support that the proportion of days with precipitation, the number of water sources, and the proportion of goats in the herd were positively associated with increased severity of RVF (the numbers of deaths and abortions). We did not find an association between any risk factors and whether RVF was reported on farms. (4) Conclusions: At the farm level we identified risk factors of RVF severity; however, there was little support for risk factors of RVF occurrence. The identification of farm-level risk factors for Rift Valley fever virus (RVFV) occurrence would support and potentially improve current prediction methods and would provide animal owners with critical information needed in order to assess their herd's risk of RVFV infection.

Abstract
Brucellosis is a worldwide zoonotic disease of socio-economic importance. Understanding the association of this disease with pregnancy outcome has the potential of contributing to the reduction of its reproductive burden in humans and animals among pastoral communities in Tanzania. A prospective cohort study was conducted in Kagera Region on pregnant women (n = 76) and gravid ruminants (121 cattle, 125 goats and 111 sheep). Exposed and non-exposed groups to brucellosis were followed for 6 months (from 15 November 2017 to 15 April 2018). Sera were collected and analysed using Rose Bengal Test (RBT) and Fluorescence polarization assay (FPA) test. Measures of effect, univariable and multivariable logistic regression analyses were computed. Positivity to both RBT and FPA tests was 21% (95% CI: 12.5-32) in pregnant women and 5% (95% CI: 3.1-8) in gravid ruminants. Among aborted cases, four women (out of nine), two cows (out of seven), two goats (out of 26) and zero sheep (out of 11) were positive to brucellosis. The abortion rate in humans and ruminants was 11.8% and 12.3%, respectively. Seropositivity to brucellosis was similar in aborted and non-aborted cases in humans (p = .08) and in ruminants (p = .2). At the population level, brucellosis was associated with abortions (population attributable risk: PAR) at 3.5% in pregnant women and at 0.5% in gravid ruminants in the study area. Infections to brucellosis were increased in exposed pregnant women (OR = 19; 95% CI: 1.8-203, p = .01) and in cattle (OR = 11; 95% CI: 1.3-88, p = .02). There is an indication that brucellosis could be contributing to abortions in pregnant women and domestic ruminants Kagera Region. Molecular tools could support more the results from serological tests to avoid cross-reaction with other pathogen agents. Control of brucellosis in animals is likely to reduce the threat of abortions in humans.

Abstract
Bovine herpesvirus 1 (BoHV-1), including commercially available modified live vaccines, readily infect the fetus and ovaries, which can cause reproductive failure. The BoHV-1 latency-reactivation cycle in sensory neurons further complicates reproductive failure because progesterone sporadically induces reactivation from latency. The progesterone receptor (PR) and Krüppel-like transcription factor 15 (KLF15) cooperatively stimulate productive infection and the immediate early transcription unit 1 (IEtu1) promoter. In addition to the IEtu1 promoter, the bICP0 gene also contains a separate early (E) promoter. In this study, we tested the hypothesis that PR and KLF family members transactivate the bICP0 E promoter. PR and KLF4 stimulated bICP0 E promoter activity and expression of late productive viral protein expression in a cooperative manner. Additional studies revealed three enhancer domains within the bICP0 E promoter were responsive to PR and KLF4. Chromatin immunoprecipitation studies demonstrated PR and KLF4 occupy bICP0 E promoter sequences in transfected Neuro-2A cells and at late times following infection of bovine kidney cells. Co-immunoprecipitation studies indicated PR and KLF4 stably interact with each other. These studies suggest cooperative activation of the bICP0 E promoter by PR and KLF4 correlate with interactions between these pioneer transcription factors.

Abstract
BACKGROUND Neospora caninum has been recognised world-wide, first as a disease of dogs, then as an important cause of abortions in cattle for the past thirty years. Over that time period, there have been improvements in the diagnosis of infection and abortion, new tests have been developed and validated, and it is timely to review progress to date. METHODS Bibliometric methods were used to identify major trends and research topics present in the published literature on N. caninum. The tools used were SWIFT-Review, VOSviewer and SciMAT, along with the published papers found in the MEDLINE, Dimensions and Web of Science databases. A systematic review of the published Neospora literature (n = 2933) was also carried out via MEDLINE and systematically appraised for publications relevant to the pathogenesis, pathology and diagnosis of Neospora abortions. RESULTS A total of 92 publications were included in the final analysis and grouped into four main time periods. In these four different time periods, the main research themes were "dogs", "abortion", "seroprevalence" and "infection". Diagnostics, including PCR, dominated the first two time periods, with an increased focus on transmission and abortions, and its risk factors in cattle. CONCLUSIONS Longitudinal analyses indicated that the main themes were consistently investigated over the last 30 years through a wide range of studies, with evolving emphasis initially on dogs and diagnostic test development, followed by application to cattle, the identification of the risk factors leading to abortion, and in the latter time periods, an understanding of the immunity and a search for vaccines.

Abstract
Bovine viral diarrhoea virus (BVDV) is a pestivirus that affects both cattle and sheep, causing an array of clinical signs, which include abortions and malformations in the offspring. Manufacturing of modified live virus (MLV) vaccines often includes the use of bovine-derived products, which implies a risk of contamination with viable BVDV. Recently, the circulation of a specific strain of BVDV 2b among Spanish sheep flocks, associated with outbreaks of abortions and malformations, and whose origin was not determined, has been observed. On February 2018, a MLV orf vaccine was applied to a 1,600 highly prolific sheep flock in the Northeast of Spain that included 550 pregnant ewes. In May 2018, during the lambing season, an unusual high rate (72.7%) of abortions, stillbirths, congenital malformations and neurological signs in the offspring was observed. It was estimated that about 1,000 lambs were lost. Three 1- to 3-day-old affected lambs and a sealed vial of the applied vaccine were studied. Lambs showed variable degrees of central nervous system malformations and presence of pestiviral antigen in the brain. Molecular studies demonstrated the presence of exactly the same BVDV 2b in the tissues of the three lambs and in the orf vaccine, thus pointing to a pestivirus contamination in the applied vaccine as the cause of the outbreak. Interestingly, sequencing at the 5'-untranslated region-(UTR) of the contaminating virus showed a complete match with the virus described in the previously reported outbreaks in Spain, thus indicating that the same contaminated vaccine could have also played a role in those cases. This communication provides a clear example of the effects of the application of this contaminated product in a sheep flock. The information presented here can be of interest in putative future cases of suspected circulation of this or other BVDV strains in ruminants.

Abstract
Universal access to contraception benefits society: unintended pregnancies, maternal mortality, preterm birth, abortions, and obesity would be reduced by increasing access to affordable contraception. Women should be able to choose when and whether to use contraception, choose which method to use, and have ready access to their chosen method. State and national government should support unrestricted access to all contraceptives. As obstetrician-gynecologists, we have a critical mandate, based on principle and mission, to step up with leadership on this vital medical and public health issue, to improve the lives of women, their families, and society. The field of Obstetrics and Gynecology must provide the leadership for moving forward. The American Gynecological and Obstetrical Society (AGOS), representing academic and public policy leaders from across all disciplines of Obstetrics and Gynecology, is well positioned to serve as a unifying organization, focused on developing a strong unified advocacy voice to fight for accessible contraception for all in the United States.

Abstract
The timing of an abortion (often measured as gestational age) can have important effects on the woman's physical health and on the cost of the procedure. To the authors' knowledge, there has been only one national analysis of the factors associated with the gestational age at abortion, but it employed data from over 20 years ago. The state-specific studies that have explored abortion timing have typically examined the effects of a specific change in abortion regulations. In this study, we employ annual, state-level data covering the 1991-2014 period that measure the frequency of abortions by gestational age. We regress these measures of abortion utilization on policy, economic, demographic, and health care infrastructure characteristics. The estimates indicate that the introduction of state restrictions on Medicaid funding of abortions is associated with a 13% increase in the rate of abortions after the first trimester. We do not find a statistically significant association between parental involvement laws and the rate or percentage of post-first-trimester abortions.

Abstract
The growing population of free-roaming dogs in informal communities in South Africa may increasingly place humans at risk of possible zoonotic infections including, but not limited to, Brucella canis. Worldwide, the prevalence of B. canis infection has increased during the last two centuries, resulting in increased reports of dog and human infections. This study investigated the risk factors associated with B. canis infection in dogs in three predefined areas: Gauteng, the Eastern Cape and Western Cape provinces, of South Africa. Dogs aged 7 months and older presented to welfare organisations and breeders in the study areas were selected for sampling. A comprehensive questionnaire on dog ownership, general health and vaccination status was completed prior to sampling. One blood sample of 8 mL was collected aseptically per dog. Then, equal amounts (4 mL) were transferred to the different vacutainer tubes. The 2-mercaptoethanol-tube agglutination tests were used after validation. Fifty-two dogs out of the combined sample of 1191 dogs from the three study areas tested positive for B. canis, representing an overall occurrence of 4.4%. A binomial logistic regression model was fitted to identify risk factors associated with B. canis in dogs within the study areas. Dog age (0.371; p 0.05) and external parasite infestation (0.311; p 0.05) were significantly associated with the B. canis infection. Ownership and sterilisation need to be further investigated as possible risk factors because both had odds ratios of 1684 and 1107, respectively, in the univariate model.

Abstract
Objective: The present study was conducted to estimate the seroprevalence and associated risk factors of bovine herpesvirus 1 (BoHV-1) in a dairy herd in the northeast of Algiers, Algeria. Materials and methods: The target area is in the northeast of Algiers with humid to semi-dry climate and known for its economically important production of cattle. A total of 1,066 randomly selected individual blood samples of dairy herd collected at 120 dairy farms from rural districts of northeast of Algiers were evaluated with antibodies against BoHV-1 using commercial enzyme-linked immunosorbent assay kits, to determine the BoHV-1 infection status of the herds. A questionnaire submitted to the farmers during collection of the blood samples was used to collect data on potential BoHV-1 associated risk factors. Results: In the present study, the estimated farm and individual animal BoHV-1 seroprevalence levels were 58.33% and 14.16%, respectively. A logistic regression analysis of the random-effects model revealed that the significant associated risk factors for the present farm and individual animal seroprevalence levels were rural district, cattle introduced to the farm, region, and hygiene. Conclusion: This study found higher seroprevalence of BoHV-1 in the northeast of Algiers. The results could be used in designing the prevention and control strategy of BoHV-1 in the northeastern part of Algeria.

Abstract
Bovine genital campylobacteriosis (BGC) is a venereal infectious disease that affects reproduction. It is caused by the Gram-negative bacillus Campylobacter fetus subspecies venerealis (Cfv), which may include the biotype intermedius. The bull is a lifelong asymptomatic carrier and transmitter of the disease. In females Cfv may cause infertility and sporadic abortion. The objective of this study is to review and discuss methods for the diagnosis of BGC, its prevalence and economic impact in South America. BGC is a worldwide distributed disease and can cause a pregnancy rate decrease of 15-25%. The farm prevalence of BGC in different regions of South American countries shows a variation between 2.3 and 100%. Discrepancies may depend on the differences on sanitary, management, and reproductive practices between farms and regions, but also on the interpretation of different diagnostic tests. Currently known laboratory tests include bacterial culture, direct immunofluorescence, immunoenzymatic assays, vaginal mucus agglutination test, PCR-based methods, histology and immunohistochemistry, which are applied and interpreted in diagnostic laboratories at different scales. Epidemiologic data of BGC in South America should be interpreted with caution. High prevalence has been reported in some studies, although the low specificity of the diagnostic tests used could lead to an overestimation of the results.

Abstract
BACKGROUND Contraceptive use and sexual health behavior remain a prominent public health concern in South Africa. Despite many government interventions, unplanned pregnancies, number of abortions, and maternal mortality remain relatively high. Due to high pregnancy levels and the stigma associated with termination of pregnancy, more women turn to unsafe and illegal abortions despite the risks involved. Risky sexual behavior pose a serious risk of contracting HIV/AIDS. The main objective of this study is to map evidence on factors influencing contraceptive use and sexual behavior in South Africa. METHODS We will conduct a scoping review guided by framework by Arksey and O'Malley. This study will search for eligible literature from peer-reviewed articles and grey literature. Databases such as PubMed/MEDLINE, American Doctoral Dissertations via EBSCO host, Union Catalogue of Theses and Dissertations (UCTD) and SA ePublications via SABINET Online and World Cat Dissertations, Theses via OCLC, and Google Scholar will be searched. Websites such as the World Health Organization (WHO) and governmental websites and statistics institutions will be explored for policies and guidelines on contraceptive use and sexual behavior. The review will be conducted on studies that were published from January 1990 to 2018. The PCC framework will be employed in this study to determine the eligibility of research question. The PRISMA chart will be utilized to report the screening of results. The MMAT Tool version 11 will be used to determine the quality of the included primary studies. RESULTS We anticipate finding a considerable number of published articles presenting evidence on contraceptive use and sexual health behavior in South Africa. Findings of this scoping review will be disseminated electronically, in print, and through peer presentation, conferences, and congresses.

Abstract
OBJECTIVES Compare hormonal contraceptive use, birth and abortion rates among teenagers in the Nordic countries. A secondary aim was to explore plausible explanations for possible differences between countries. DESIGN Ecological study using national registry data concerning births and abortions among all women aged 15-19 years residing in Denmark, Finland, Iceland, Norway and Sweden 2008-2015. Age-specific data on prescriptions for hormonal contraceptives for the period 2008-2015 were obtained from national databases in Denmark, Norway and Sweden. SETTING Denmark, Finland, Iceland, Norway and Sweden. PARTICIPANTS Women 15-19 years old in all Nordic countries (749 709) and 13-19 years old in Denmark, Norway and Sweden (815 044). RESULTS Both annual birth rates and abortion rates fell in all the Nordic countries during the study period. The highest user rate of hormonal contraceptives among 15-19-year-olds was observed in Denmark (from 51% to 47%) followed by Sweden (from 39% to 42%) and Norway (from 37% to 41%). Combined oral contraceptives were the most commonly used methods in all countries. The use of long-acting reversible contraceptives (LARC), implants and the levonorgestrel-releasing intrauterine systems, were increasing, especially in Sweden and Norway. In the subgroup of 18-19-year-old teenagers, the user rates of hormonal contraceptives varied between 63% and 61% in Denmark, 56% and 61% in Norway and 54% and 56% in Sweden. In the same subgroup, the steepest increase of LARC was seen, from 2% to 6% in Denmark, 2% to 9% in Norway and 7% to 17% in Sweden. CONCLUSIONS Birth and abortion rates continuously declined in the Nordic countries among teenagers. There was a high user rate of hormonal contraceptives, with an increase in the use of LARC especially among the oldest teenagers.

Abstract
Sexuality education is an extremely controversial topic in countries like Pakistan where any dialogue regarding sexual practices is considered taboo. Yet, it is a country with a high prevalence of abortions and sexually transmitted illnesses (STIs). Current knowledge about such issues in the general public is also very poor. Hence, it is extremely important to discuss the advantages of having sexual education programs in Pakistan and analyze the current impact of an absence of such programs and public awareness campaigns.

Abstract
Up to 50% of recurrent miscarriage cases in women occur without an underlying etiology. In the current prospective case–control study, we determined the impact of CGG trinucleotide expansions of the fragile-X mental retardation 1 (FMR1) gene in 49 women with unexplained recurrent miscarriages. Case group consisted of women with two or more unexplained consecutive miscarriages. Blood samples were obtained and checked for the presence of expanded alleles of the FMR1 gene using PCR. Patients harboring the expanded allele, with a threshold set to 40 repeats, were further evaluated by sequencing. The number of abortions each woman had, was not associated with her respective CGG repeat number (P=0.255). The repeat sizes of CGG expansion in the FMR1 gene were significantly different in the two population groups (P=0.027). All the positive cases involved intermediate zone carriers. Hence, the CGG expanded allele of the FMR1 gene might be associated with unexplained multiple miscarriages; whether such an association is coincidental or causal can be confirmed by future studies using a larger patient cohort.

Abstract
Introduction L'organisation mondiale de santé (OMS) estime que chaque année dans le monde 585 000 femmes meurent de complications liés à la grossesse, à l'accouchement, aux suites de couche et à l'avortement (ce dernier contribuant pour 13% des décès maternels). La GEU est responsable de 10% de mortalité maternelle au premier trimestre de la grossesse. Le taux de mortalité maternelle reste élevé au Cameroun, estimé à 782 pour 100 000 naissances vivantes selon EDS-MICS 2011. La contribution de ces deux entités dans la mortalité maternelle étant peu documentée dans notre pays, nous avons entrepris de réaliser cette étude avec pour objectif d'évaluer la contribution des avortements et des GEU dans la mortalité maternelle au Cameroun. Méthodes il s'agissait d'une étude rétrospective et analytique. Nous avons colligé tous les dossiers des patientes enceintes et décédées avant la 28ème semaine de grossesse, dans trois hôpitaux universitaires: Hôpital Central de Yaoundé (HCY), Hôpital Gynéco-Obstétrique et Pédiatrique de Yaoundé (HGOPY), Centre Hospitalier et Universitaire (CHU), sur la période allant du 1er juin 2011 au 31 mai 2016, soit sur cinq ans. Les données étaient compilées sur une fiche technique préétablie et testée, saisies en utilisant le logiciel CS pro 6.2 et analysées par le logiciel SPSS 20. Les tests statistiques de comparaison utilisés étaient le Khi 2 et le test de Fischer en fonction des effectifs. Le seuil de significativité était retenu pour P < 005. Résultats Tous avons enregistré 524 décès maternels pour 31116 naissances vivantes, soit un taux de mortalité maternelle (TMM) de 1538.9/100 000 naissances vivantes. Sur les 524 décès maternels, 414 dossiers étaient exploitables, parmi lesquels, 100 (soit 24.2%) concernaient les avortements et 24 (soit 5.8%) concernaient les grossesses extra-utérines, ces 2 entités contribuaient ainsi pour 30% de décès maternels (124 dossiers sur 414). L'analyse des 124 dossiers montre que l'âge moyen était de 27.58 +/-6 ans avec des extrêmes de 18 et 48. La tranche d'âge de 20 à 24 ans était la plus représentée (33.1%), suivie de celle de 25 à 29 ans (24.19%). Les célibataires constituaient 75%, les ménagères 36.7 %, de niveau d'instruction secondaire dans 62.5% et multigestes constituaient 36.1% de notre échantillon. Aucune consultation prénatale n'avait été initiée dans 73.4% et seulement 2.4% en avaient fait au moins 4. Les complications ayant conduit au décès étaient dominées par les hémorragies et les infections. Conclusion Les avortements et grossesse extra-utérines restent des causes majeures de la mortalité maternelle dans notre pays. Nous recommandons un renforcement de la planification familiale pour limiter les grossesses non désirées et une prise en charge par assistance socio-économique des patientes à risques.

Abstract
The aim of this study is to examine the reproductive history of human immunodeficiency virus (HIV)-positive women, before and after HIV diagnosis, to describe the characteristics of women with pregnancies after HIV diagnosis, and to assess the prevalence of mother-to-child transmission.A cross-sectional study was performed among women within reproductive ages (18-49) selected from the cohort in the Spanish AIDS Research Network (CoRIS). A descriptive analysis of the pregnancy outcomes was made according to women's serostatus at the moment of pregnancy and association of women's characteristics with having pregnancy after HIV diagnosis was evaluated using logistic regression models.Overall, 161 women were interviewed; of them, 86% had been pregnant at least once and 39% after HIV diagnosis. There were 347 pregnancies, 29% of them occurred after HIV diagnosis and in these, 20% were miscarriages and 29% were voluntary termination of pregnancy. There were 3 cases of mother-to-child transmission among the 56 children born from HIV-positive mothers; in these cases, women were diagnosed during delivery. Having a pregnancy after HIV diagnosis was more likely when the younger women were at the time of diagnosis: odds ratio (OR) = 1.29 (95% confidence interval 0.40-4.17) for 25 to 29 years old, OR = 0.59 (0.15-2.29) for 30 to 34 years old, OR = 0.14 (0.03-0.74) for ≥35 years old, compared with those <25 years at diagnosis, who were diagnosed for ≥5 years (OR = 5.27 [1.71-16.18]), who received antiretroviral treatment at some point (OR = 9.38 [1.09-80.45]), and who received information on reproductive health (OR = 4.32 [1.52-12.26]).An important number of pregnancies occurred after HIV diagnosis, reflecting a desire for motherhood in these women. Reproductive and sexual health should be tackled in medical follow-ups.

Abstract
BACKGROUND The number of abortions of fetuses with Down syndrome in England and Wales reported by the Department of Health (DH) differs from that reported by the National Down Syndrome Cytogenetic Register (NDSCR). The aim of this study was to investigate the reasons for this. METHODS Abortions in 2011 and 2012 from DH were matched to those from NDSCR. The number of cases not reported to either source was estimated. RESULTS An estimated 2240 abortions of fetuses with Down syndrome occurred in 2011/12; NDSCR estimated 2208 and DH 1100. One thousand and six abortions were identified in both data sets, including 145 (14%) which were not recorded by DH as having Down syndrome. Abortions in NDSCR that were not matched in DH occurred throughout England and Wales and at all gestational ages. An estimated 61 abortions of fetuses with Down syndrome were not reported to DH or NDSCR. CONCLUSIONS The number of abortions of fetuses with Down syndrome reported by the NDSCR is more complete than that reported by the DH. DH data for abortions with other congenital anomalies are also likely to be underestimates, and more accurate estimates are available from BINOCAR regional congenital anomaly registers.

Abstract
BACKGROUND During the 2009 influenza A (H1N1) pandemic, pregnant women were at risk for severe influenza illness. This concern was complicated by questions about vaccine safety in pregnant women that were raised by anecdotal reports of fetal deaths after vaccination. METHODS We explored the safety of influenza vaccination of pregnant women by linking Norwegian national registries and medical consultation data to determine influenza diagnosis, vaccination status, birth outcomes, and background information for pregnant women before, during, and after the pandemic. We used Cox regression models to estimate hazard ratios for fetal death, with the gestational day as the time metric and vaccination and pandemic exposure as time-dependent exposure variables. RESULTS There were 117,347 eligible pregnancies in Norway from 2009 through 2010. Fetal mortality was 4.9 deaths per 1000 births. During the pandemic, 54% of pregnant women in their second or third trimester were vaccinated. Vaccination during pregnancy substantially reduced the risk of an influenza diagnosis (adjusted hazard ratio, 0.30; 95% confidence interval [CI], 0.25 to 0.34). Among pregnant women with a clinical diagnosis of influenza, the risk of fetal death was increased (adjusted hazard ratio, 1.91; 95% CI, 1.07 to 3.41). The risk of fetal death was reduced with vaccination during pregnancy, although this reduction was not significant (adjusted hazard ratio, 0.88; 95% CI, 0.66 to 1.17). CONCLUSIONS Pandemic influenza virus infection in pregnancy was associated with an increased risk of fetal death. Vaccination during pregnancy reduced the risk of an influenza diagnosis. Vaccination itself was not associated with increased fetal mortality and may have reduced the risk of influenza-related fetal death during the pandemic.

Abstract
A group of 32 dairy herds, recently infected with bovine virus diarrhoea virus (BVDV), was compared with a control group consisting of 75 BVDV free herds during a 3-year-period. Variables related to reproduction were registered. Results of multiple antibody examinations in bulk milk as well as samples of milk and blood from younger animals were used to select the herds. The incidence of abortions was statistically significantly different in the 2 groups, while the number of stillbirths, weak born calves, and congenital anomalies was not. Other variables such as percentage of non return, average number of inseminations per cow and calving interval showed during the study a trend to improve in the BVDV group, while they remained stable in the control group.

Abstract
Sixtyfour compacted morulae and blastocysts were bisected with a microscalpel. The majority of the demi-embryos (n = 122) were reinserted into separate zona pellucidae (ZP) before non-surgical transfer to 113 synchronized recipients, as singles (n = 98) (DE-S) or in pairs (n = 30) (DE-P). Thirty non-manipulated embryos (E) were transferred during the same period and served as controls. Pregnancies were diagnosed by rectal palpation 4-7 weeks after transfer. The pregnancy rates for DE-S, DE-P and E were 32%, 53% and 40%, respectively (P greater than 0.05). A substantial number of abortions were recorded between 50 and 250 days of pregnancy among the recipients with DE-S. The fetal survival rate for DE-S was reduced to 21% and significantly lower (p less than 0.05) than the survival rates of DE-P (43%) and E (40%). The quality of DE and the presence of ZP did not significantly influence the results. No conclusive reasons for the fetal loss could be found but different possibilities are discussed.

Abstract
ELISA was adapted for the study of antigenic relations among important Campylobacters and for the presence of anti-campylo-bacter antibodies in 394 sheep and 265 cattle. Rabbit anti-C. jejuni, C. coli, G. fetus subsp. fetus and C. laridis heat-stable antigen sera were evaluated against 29 Campylobacter strains and 6 other bacteria. Anti-C. jejuni and G. coli reacted strongly with homologous antigens and weakly with C. fetus subsp. fetus, C. laridis and C. fecalis antigens. C. fetus subsp. fetus serum reacted mainly with its homologous antigen. C. laridis serum showed closer reactivity to C. jejuni than to C. fetus subsp. fetus, C. coli and C. fecalis. Insignificant cross-reactions were observed with Y. enterocolitica, S. dublin and E. aerogenes heat-stable antigens, Ewes vaccinated with C. fetus subsp. fetus bacterin showed higher ELISA titers against C. fetus subsp. fetus antigens than non-vaccinated ewes or rams. Twenty-five percent of the vaccinated animals showed titers as low as 95 % of the non-vaccinated animals. In cattle the lowest antibody titers against C. fetus subsp. fetus, C. jejuni, C. coli and C. laridis antigens were exhibited by the precolostrum sera followed by the postcolostrum and adult sera. These studies demonstrated the applicability of the ELISA test in seroepidemiological investigations concerning the distribution and significance of Campylobacter antibodies in food animal sera.
