    This study examines the social acceptance of young (under-18) pregnancy by assessing people's acceptance of young pregnancy and abortion in relation to deprivation. A cross-sectional survey design was conducted in two relatively affluent and two relatively deprived local authorities in London (n=570). Contrary to previous findings, participants…

  2. Intermittent auscultation of fetal heart rate during labour - a widely accepted technique for low risk pregnancies: but are the current national guidelines robust and practical?

    Intermittent auscultation of fetal heart rate is an accepted practice in low risk labours in many countries. National guidelines on intrapartum fetal monitoring were critically reviewed regarding timing and frequency of intermittent auscultation. Hypothetical but plausible examples are presented to illustrate that it may be possible to miss significant fetal distress with strict adherence to current guidelines. Opinion is forwarded that intermittent auscultation should be performed for 60 seconds before and after three contractions over about 10 min every half an hour in the first stage of labour. Reasons are put forward to show how this could be more practical and patient friendly and at the same time could improve detection of fetal distress. The current recommendation of intermittent auscultation every 15 min in the first stage is associated with poor compliance and leads to unnecessary burden, stress and medicolegal liability for birth attendants. Modification of current national guidelines would be desirable.

    The effect of military deployment and perceived availability and source of community support on women's acceptance of pregnancy were examined in each trimester of pregnancy at four military bases. The sample was 503 primigravida or multigravida women eligible for care in the military medical system. Military deployment and community support had a statistically significant effect on pregnancy acceptance. Gravidas with deployed husbands had higher conflict for accepting pregnancy than gravidas without deployed spouses. Community support had a significant positive effect on pregnancy acceptance. Women perceiving support predominantly from off-base versus on-base communities had significantly higher conflict with acceptance of pregnancy. Findings point to improved maternal acceptance of pregnancy with paternal presence and community support in the event of military deployment.

    Plains bison (Bison b. bison) centered on Yellowstone National Park are chronically infected with brucellosis (Brucella abortus) and culled along the park boundaries to reduce the probability of disease transmission to domestic livestock. We evaluated the relationship between pregnancy rates and age, dressed carcass weight, and serological status for brucellosis among bison culled from the central Yellowstone subpopulation during the winters of 1996–1997, 2001–2002, and 2002–2003. A model with only dressed carcass weight was the best predictor of pregnancy status for all ages with the odds of pregnancy increasing by 1.03 (95% CI = 1.02–1.04) for every 1-kg increase in weight. We found no effect of age or the serological status for brucellosis on pregnancy rates across age classes; however, we did find a positive association between age and pregnancy rates for bison ≥2 years old. Bison ≥2 years old had an overall pregnancy rate of 65% with markedly different rates in alternate ages for animals between 3 and 7 years old. Pregnancy rates were 0.50 (95% CI = 0.31–0.69) for brucellosis positive and 0.57 (95% CI = 0.34–0.78) for brucellosis negative 2- and 3-year-olds and 0.74 (95% CI = 0.60–0.85) in brucellosis positive and 0.69 (95% CI = 0.49–0.85) in brucellosis negative bison ≥4 years old. Only 1 of 21 bison <2 years old was pregnant. Our findings are important to accurately predict the effects of brucellosis on Yellowstone bison population dynamics. We review our results relative to other studies of Yellowstone bison that concluded serological status for brucellosis influences pregnancy rates.

    Public financing of IVF aims at increasing access to treatment while decreasing the expenses associated with multiple pregnancies. Critics argue that it is associated with lower pregnancy rates. This study compared cycles performed during 2009 (before implementation of Quebec's public IVF programme; period I) to those performed in the year following implementation (period II) in a single IVF centre. First fresh cycles in period I (499 women) and first fresh cycles (815 women) along with their corresponding first vitrified-warmed transfer (271 women) in period II were evaluated. From period I to period II, single-embryo transfer increased from 17.3% to 85.0% (P<0.001), multiple ongoing pregnancy rate decreased from 25.8% to 1.6% (P<0.001) and ongoing pregnancy rate decreased from 31.9% to 23.3% (P=0.001). During period II, the ongoing pregnancy rate per vitrified-warmed embryo transfer was 19.2%, leading to a cumulative ongoing pregnancy rate per initiated cycle of 29.7%, which was not different to the pregnancy rate per fresh cycle during period I (31.9%). To conclude, Quebec's public IVF programme decreased multiple pregnancy rates while maintaining an acceptable cumulative ongoing pregnancy rate, a more precise outcome to evaluate the impact of public IVF programmes.

    Kidney transplantation is the treatment of choice for end-stage renal disease (ESRD). Kidney transplantation recipients live longer and have better quality of life than patients on dialysis. Hypothalamic gonadal dysfunction in females who have ESRD may be reversed within the first few months after kidney transplantation, such as the ability to have children. Despite thousands of successful pregnancies in transplantation recipients, there is limited information about it. In this study, we evaluated the pregnancy rates and live birth rates in women (n = 133) who underwent kidney transplantation in our center from 1983 to 2010. Recipients of a second kidney transplantation and recipients of multiorgan transplantations were excluded. We observed 33 pregnancies with 11 live births (33.3%), 12 spontaneous abortions (36.36%), and 10 therapeutic abortions (30.3%). The pregnancy rate was 18%. The live birth rate was 33.3%. Therapeutic abortions were 36.3%, and the pregnancies resulting in fetal loss were 30.3%. The pregnancies were identified in 32 women. The majority of women (n = 32; 96.9%) had a single pregnancy, whereas 1 woman (3.1%) had two pregnancies. In our series, the pregnancy rates for kidney transplantation recipients were markedly lower and decreased more rapidly than those reported in the general population.

    The psychophysical test, the rating of acceptable load (RAL) were used to assess acceptable weights for dynamic lifting in postal workers engaged in sorting parcels. The standard test (RALSt) and a work-simulating test (RALW) were administered to 103 volunteers: all experienced male sorters. In the RALSt, subjects selected the weight which would be acceptable for lifting in a box with handles from table to floor and back to the table once every 5 min for the working day. for the RALW, the box was without handles and the weight was chosen to be acceptable for transfer 4-6 times/min from a table to the parcel container and back to the table. Both tests were made during normal working hours at postal sorting centres. The overall means for RALSt and RALW were 16.4 kg and 9.4 kg respectively (p < 0.001): both being substantially higher than the average parcel weight of 4 kg. The RALSt and RALW tests proved to be repetitive and sensitive for differentiating the effects of load and task variable in actual manual material handling. Thus they appear to be applicable to the evaluation of manual materials handling problems.

    This report is one in a series of PVUSA reports on PVUSA experiences and lessons learned at the demonstration sites in Davis and Kerman, California, and from participating utility host sites. During the course of approximately 7 years (1988--1994), 10 PV systems have been installed ranging from 20 kW to 500 kW. Six 20-kW emerging module technology arrays, five on universal project-provided structures and one turnkey concentrator, and four turnkey utility-scale systems (200 to 500 kW) were installed. PVUSA took a very proactive approach in the procurement of these systems. In the absence of established procurement documents, the project team developed a comprehensive set of technical and commercial documents. These have been updated with each successive procurement. Working closely with vendors after the award in a two-way exchange provided designs better suited for utility applications. This report discusses the PVUSA procurement process through testing and acceptance, and rating of PV turnkey systems. Special emphasis is placed on the acceptance testing and rating methodology which completes the procurement process by verifying that PV systems meet contract requirements. Lessons learned and recommendations are provided based on PVUSA experience.

    Background: For infertile women aged over 35 years, failure of the ZP (zona pellucida) to rupture is believed to be associated with a decreased implantation rate in in vitro fertilization (IVF) or intra cytoplasmic sperm injection (ICSI). Objective: In this research, laser assisted hatching (LAH) was offered to patients with advanced maternal age to evaluate a possible benefit. Materials and Methods: Nine hundred thirty two cycles of IVF/ICSI in females were analyzed. Women included in this study were allocated in 4 groups. In group I and II, embryos were cultured and transferred with and without LAH in women aged ≤35, whereas embryos of group III and IV were examined with and without LAH in women aged ≥ 35. Laser manipulations were performed using a suturn-Tm3 system using 2-3 pulses of 0.8 millisecond with 400 voltage duration. The size of the hole made in the zona was measured to be 5-10 µm, depending on the zona thickness of each individual embryo. Results: The performance of LAH significantly increased clinical pregnancy rates in all patients. In group I and II, the chemical (50.99% and 31.61% respectively), clinical (50% and 30.69% respectively) and multiple pregnancies (22.27% and 5.94% respectively) significantly differ between these groups. In the patients with advanced female age ≥35 the performance of LAH significantly increased chemical (30.12%) and clinical pregnancy (27.71%) rates compared to whom without LAH (18.96% and 16.37% respectively). Conclusion: Our data demonstrate in the patients who were less than 35 years old, multiple pregnancy rates were significantly increased compared to other groups who aged over 35 years old. In addition benefit of LAH in improving pregnancy rates after IVF or ICSI in women of advanced age (≥35) was shown. PMID:25587254

    Objectives The aim of this study was to evaluate the effects of non-surgical treatment of periodontal disease during the second trimester of gestation on adverse pregnancy outcomes. Material and Methods Pregnant patients during the 1st and 2nd trimesters at antenatal care in a Public Health Center were divided into 2 groups: NIG – "no intervention" (n=17) or IG- "intervention" (n=16). IG patients were submitted to a non-surgical periodontal treatment performed by a single periodontist consisting of scaling and root planning (SRP), professional prophylaxis (PROPH) and oral hygiene instruction (OHI). NIG received PROPH and OHI during pregnancy and were referred for treatment after delivery. Periodontal evaluation was performed by a single trained examiner, blinded to periodontal treatment, according to probing depth (PD), clinical attachment level (CAL), plaque index (PI) and sulcular bleeding index (SBI) at baseline and 35 gestational weeks-28 days post-partum. Primary adverse pregnancy outcomes were preterm birth (<37 weeks), low birth weight (<2.5 kg), late abortion (14-24 weeks) or abortion (<14 weeks). The results obtained were statistically evaluated according to OR, unpaired t test and paired t test at 5% significance level. Results No significant differences were observed between groups at baseline examination. Periodontal treatment resulted in stabilization of CAL and PI (p>0.05) at IG and worsening of all periodontal parameters at NIG (p<0.0001), except for PI. Significant differences in periodontal conditions of IG and NIG were observed at 2nd examination (p<0.001). The rate of adverse pregnancy outcomes was 47.05% in NIG and 6.25% in IG. Periodontal treatment during pregnancy was associated to a decreased risk of developing adverse pregnancy outcomes [OR=13.50; CI: 1.47-123.45; p=0.02]. Conclusions Periodontal treatment during the second trimester of gestation contributes to decrease adverse pregnancy outcomes. PMID:21552714

    Appendectomy is the most common non-gynecologic surgery performed during pregnancy. Little data exist on the accuracy of imaging studies in the diagnosis of appendicitis in pregnancy. The objective of this study was to evaluate the probability of ultrasound and computed tomography (CT) scan in diagnosing appendicitis in pregnancy, as reflected in the negative appendectomy rate. We retrospectively reviewed the charts of 86 pregnant women who underwent an appendectomy between January 1, 1997 and January 1, 2006. Patients were divided into three groups: clinical evaluation, ultrasound, and ultrasound followed by a CT scan. The clinical evaluation group had 13 patients, with a negative appendectomy rate of 54% (7/13). Fifty-five patients underwent an ultrasound alone, with a negative appendectomy rate 36% (20/55). In the ultrasound/CT group (n=13), the negative appendectomy rate was 8% (1/13). There was a significant reduction in the negative appendectomy rate in the ultrasound/CT scan group compared to clinical evaluation group (54 vs 8%, p<0.05). This reduction was not achieved in the ultrasound group when compared to the clinical evaluation group or the ultrasound/CT group (p=0.05). A significant reduction was achieved when the ultrasound/CT group was compared to the patients in the ultrasound only group who had a normal or inconclusive ultrasound (p<0.05). Our data documents a very high negative appendectomy rate in the pregnant patient. We recommend an ultrasound followed by a CT scan in patients with a normal or inconclusive ultrasound.

  13. Rates of ectopic pregnancy, sterility follow PID rise.

    PubMed

    1980-05-01

    500,000 cases of PID (pelvic inflammatory disease) are reported annually in the US, with 34,000 to 92,000 women becoming sterile as a consequence of the disease. In addition, the contraceptive methods women use during their exposure to PID-causing agents may directly affect their relative risk of developing PID, at an annual cost of $2.7 billion in health-care expenses. Another sequelae of PID is ectopic pregnancy. The STD epidemic years from 1965 to 1975 are projected to increase the rate of ectopic pregnancies to 50,000 a year, or one for every 60 live births before leveling off. By 1990, 1 out of 32 women will have had an ectopic pregnancy. Tubal occlusion can result in involuntary infertility. The National Survey of Family Growth estimates that the prevalence of infertile women aged 15 to 44 who are married and use no contraceptive method has increased in the past 2-1/2 years from 2.7% to 6.1%. These women number 142,000 annually and resort to nonsurgical sterilization, with PID as a major reason. Gonococcal PID accounts for 34,000 to 92,000 women becoming involuntarily sterile each year. However, over 80% of PID is nongonococcal PID, which is a worst disease. Chronic PID and infertility are found "more often in women who have had nongonococcal PID than in women who have had gonococcal PID." Etiologic organisms of PID include gonorrhea; E. coli, anaerobes and Chlamydia trachomatis.

  14. Fetal tolerance in human pregnancy--a crucial balance between acceptance and limitation of trophoblast invasion.

    PubMed

    During human pregnancy the semi-allogeneic/allogeneic fetal graft is normally accepted by the mother's immune system. Initially the contact between maternal and fetal cells is restricted to the decidua but during the 2nd trimester it is extended to the entire body. Two contrary requirements influence the extent of invasion of extravillous fetal trophoblast cells (EVT) in the maternal decidua: anchorage of the placenta to ensure fetal nutrition and protection of the uterine wall against over-invasion. To establish the crucial balance between tolerance of the EVT and its limitation, recognition of the semi-allogeneic/allogeneic fetal cell by maternal leukocytes is prerequisite. A key mechanism to limit EVT invasion is induction of EVT apoptosis. Apoptotic bodies are phagocytosed by antigen-presenting cells (APC). Peptides from apoptotic cells are presented by APC cells and induce an antigen-specific tolerance against the foreign antigens on EVT cells. These pathways, including up-regulation of the expression of IDO, IFNgamma and CTLA-4 as well as the induction of T(regulatory) cells, are general immunological mechanisms which have developed to maintain peripheral tolerance to self-antigens. Together these data suggest that the mother extends her "definition of self" for 9 months on the foreign antigens of the fetus.

    High-resolution transvaginal ultrasound has facilitated the diagnosis of adenomyosis. This study determined the prevalence of this finding in infertile women and its effect on the outcome of IVF/intracytoplasmic sperm injection (ICSI). This prospective study evaluated 275 consecutive women, commencing IVF/ICSI for the first time. Inclusion criteria were adequate ovarian reserve. Women with fibroids or a previous myomectomy were excluded. All women were screened for adenomyosis by transvaginal ultrasound on three separate occasions. The control group included 256 women and the adenomyosis group included 19 women. There was no significant difference in the ages of women, FSH, cause of infertility, body mass index, total dose of gonadotrophin used and number of oocytes collected between the two groups. However, women with adenomyosis had a higher mean antral follicle count (P=0.006). The clinical pregnancy rate (22.2% versus 47.2%) and ongoing pregnancy rate (11.1% versus 45.9%) were significantly lower in women with adenomyosis and the miscarriage rate (50.0% versus 2.8%) was significantly higher in women with adenomyosis (all P<0.001). Ultrasound evidence of adenomyosis is found in a significant number of women presenting with infertility and has a negative impact on the outcome of IVF/ICSI. This paper suggests that a common condition known as adenomyosis is associated with a reduced success following fertility treatment such as IVF. The diagnosis of adenomyosis has been greatly facilitated by the advent of high-resolution transvaginal ultrasound. This was a study including 275 consecutive women who were commencing IVF for the first time. Comparing women who did not have adenomyosis and those that did, the clinical and ongoing pregnancy rates were both lower in women with adenomyosis (22.2% versus 47.2% and 11.1% versus 45.9%, respectively). So, fewer women with adenomyosis became pregnant and had an ongoing pregnancy. The miscarriage rate was higher in women with

    Introduction Infertility has a high prevalence in the general population, affecting ∼ 5 to 15% of couples in reproductive age. The assisted reproduction techniques (ART) include in vitro manipulation of gametes and embryos and are an important treatment indicated to these couples. It is well accepted that the implantation rate is positively influenced by the morphology of transferred embryos. However, we question if, apart from the assessment of embryo morphology, the number of produced embryos per cycle is also related to pregnancy rates in the first fresh transfer cycle. Purpose To evaluate the clinical pregnancy rate according to the number of formed embryos and the transfer of top quality embryos (TQEs). Methods In a retrospective cohort study, between January 2011 and December 2012, we evaluated women who underwent intracytoplasmic sperm injection (ICSI), aged < 40 years, and with at least 1 formed embryo fresh transferred in cleavage stage. These women were stratified into 3 groups according to the number of formed embryos (1 embryo, 2-3 and ≥ 4 embryos). Each group was divided into 2 subgroups according to the presence or not of at least 1 transferred TQE (1 with TQE; 1 without TQE; 2-3 with TQE, 2-3 without TQE; ≥ 4 with TQE; ≥ 4 without TQE). The clinical pregnancy rates were compared in each subgroup based on the presence or absence of at least one transferred TQE. Results During the study period, 636 women had at least one embryo to be transferred in the first fresh cycle (17.8% had 1 formed embryo [32.7% with TQE versus 67.3% without TQE], 42.1% of women had 2-3 formed embryos [55.6% with TQE versus 44.4% without TQE], and 40.1% of patients had ≥ 4 formed embryos [73.7% with TQE versus 26.3% without TQE]). The clinical pregnancy rate was significantly higher in the subgroup with ≥ 4 formed embryos with at least 1 transfered TQE (45.2%) compared with the subgroup without TQE (28.4%).

    We tested functionality and acceptability of a wireless fetal monitoring prototype technology in pregnant women in an inpatient labor unit in the United States. Women with full-term singleton pregnancies and no evidence of active labor were asked to wear the prototype technology for 30 minutes. We assessed functionality by evaluating the ability to successfully monitor the fetal heartbeat for 30 minutes, transmit this data to Cloud storage and view the data on a web portal. Three obstetricians also rated fetal cardiotocographs on ease of readability. We assessed acceptability by administering closed and open-ended questions on perceived utility and likeability to pregnant women and clinicians interacting with the prototype technology. Thirty-two women were enrolled, 28 of whom (87.5%) successfully completed 30 minutes of fetal monitoring including transmission of cardiotocographs to the web portal. Four sessions though completed, were not successfully uploaded to the Cloud storage. Six non-study clinicians interacted with the prototype technology. The primary technical problem observed was a delay in data transmission between the prototype and the web portal, which ranged from 2 to 209 minutes. Delays were ascribed to Wi-Fi connectivity problems. Recorded cardiotocographs received a mean score of 4.2/5 (± 1.0) on ease of readability with an interclass correlation of 0.81(95%CI 0.45, 0.96). Both pregnant women and clinicians found the prototype technology likable (81.3% and 66.7% respectively), useful (96.9% and 66.7% respectively), and would either use it again or recommend its use to another pregnant woman (77.4% and 66.7% respectively). In this pilot study we found that this wireless fetal monitoring prototype technology has potential for use in a United States inpatient setting but would benefit from some technology changes. We found it to be acceptable to both pregnant women and clinicians. Further research is needed to assess feasibility of using this

    Heat stress has adverse effects on fertility of dairy animals. Decline in fertility is linearly associated with an increase in combination of both temperature and humidity. The purpose of this study was to investigate the relationship between temperature humidity index (THI) and the pregnancy rate of Murrah buffaloes in a subtropical climate. The effects of genetic and non-genetic factors viz., sire, parity, period of calving and age group at first calving were found non-significant on pregnancy rate. The effect of THI was found significant (p<0.001) on pregnancy rate of Murrah buffaloes calved for first time and overall pregnancy rate. The threshold THI affecting the pregnancy rate was identified as THI 75. The months from October to March showed THI<75 and considered as non heat stress zone (NHSZ), while months from April to September were determined as heat stress zone (HSZ) with THI≥75. The lowest overall pregnancy rate (0.25) was obtained in July with THI 80.9, while the highest overall pregnancy rate (0.59) was found in November with THI 66.1. May and June were identified as critical heat stress zone (CHSZ) within the HSZ with maximum decline (−7%) in pregnancy rate with per unit increase in THI. The highest overall pregnancy rate was estimated as 0.45 in NHSZ with THI value 56.7 to 73.2. The pregnancy rate was found to have declined to 0.28 in HSZ with THI 73.5 to 83.7. However, the lowest pregnancy rate was estimated as 0.27 in CHSZ with THI value 80.3 to 81.6. PMID:26104398

    A pregnant patient in second trimester scheduled for posterior fossa craniotomy in prone position is a challenge for the anesthesiologist. Things to consider are physiological changes during pregnancy, non-obstetric surgery in pregnant patients, neuroanesthetic principles, effects of prone positioning, and need for fetal heart rate (FHR) monitoring. We have described the anesthetic management of this case and discussed intra-operative FHR monitoring including controversies about its role, indications, and various options available as per fetal gestational age. In our case we attempted intermittent intra-operative FHR monitoring to optimize maternal positioning and fetal oxygenation even though the fetus was pre-viable. However the attempt was abandoned due to practical difficulties with prone positioning. Patient made good neurological recovery following the procedure and delivered a healthy term baby 4 months later. Decisions regarding fetal monitoring should be individualized based on viability of the fetus and feasibility of emergency cesarean delivery. Good communication between a multidisciplinary team involving neurosurgeon, anesthesiologist, obstetrician, and neonatologist is important for a successful outcome for mother and fetus. We conclude that prone position neurosurgery can safely be carried out in a pregnant patient with pre-viable fetus without FHR monitoring.

    AIM: To correlate the ease or difficulty of embryo transfer and blood at catheter tip with pregnancy rate when embryo transfer (ET) was performed by the same operator using soft catheter. MATERIALS AND METHODS: A retrospective analysis of 342 patients who underwent in vitro fertilization or ICSI cycle from January 2008 to December 2010 in a single centre was done. The type of transfer was divided into two groups: ‘easy’ or ‘difficult’. Transfer was considered difficult when additional instrumentation was required or firmer catheter was used or required changing of catheter. Patients undergoing cryo-preserved ET were excluded from the study. RESULTS: On the day of transfer in 284 (83%) patients, ET was easy and difficulty was encountered in 58 (17%) patients. Blood at catheter was seen in 101 (29.53%) patients. In the group of 58 difficult transfers, 10 pregnancies resulted with a clinical pregnancy rate of 17.2%, while 67 pregnancies resulted in 284 cycles of easy transfer with clinical pregnancy rate of 23.6% (P value = 0.045). While no significant difference was seen in pregnancies with blood on outer catheter and blood less transfer, there was significant reduction in pregnancy rate when blood was present on catheter tip compared to bloodless transfer (13.3% v/s 24.1; P value = 0.032). CONCLUSION: Reduction in clinical pregnancy rate is seen with difficult ETs, more when blood is present at the catheter tip. PMID:23531644

    Objective Heparin can modulate proteins, and influence processes involved in implantation and trophoblastic development. This study aimed to assess the improvement of clinical pregnancy and implantation rates after local intrauterine injection of low-molecular-weight heparin (LMWH) in patients undergoing intracytoplasmic sperm injection (ICSI). Methods A randomised case/control design was followed in women scheduled for ICSI. The study arm was injected with intrauterine LMWH during mock embryo transfer immediately following the ovum pickup procedure, while the control arm was given an intrauterine injection with a similar volume of tissue culture media. Side effects, the clinical pregnancy rate, and the implantation rate were recorded. Results The pregnancy rate was acceptable (33.9%) in the LMWH arm with no significant reported side effects, confirming the safety of the intervention. No statistically significant differences were found in the clinical pregnancy and implantation rates between both groups (p=0.182 and p=0.096, respectively). The odds ratio of being pregnant after intrauterine injection with LMWH compared to the control group was 0.572 (95% confidence interval [CI], 0.27−1.22), while the risk ratio was 0.717 (95% CI, 0.46−1.13; p=0.146). No statistical significance was found between the two groups in other factors affecting implantation, such as day of transfer (p=0.726), number of embryos transferred (p=0.362), or embryo quality. Conclusion Intrauterine injection of LMWH is a safe intervention, but the dose used in this study failed to improve the outcome of ICSI. Based on its safety, further research involving modification of the dosage and/or the timing of administration could result in improved ICSI success rates. PMID:28090465

    Urine pregnancy diagnostic test is easily available. It is a requirement of the screening program for Myanmar workers who pursue employment in Thailand. Only a few studies have estimated population pregnancy rates using objective and laboratory-based criteria. Here, the authors performed a study on laboratory-measured pregnancy rates among Myanmar workers who pursue employment in Thailand from an experience in a tertiary hospital in Thailand. The data from medical records of the female Myanmar migrant workers who got a diagnostic urine pregnancy test at Division of Laboratory Medicine, King Chulalongkorn Memorial Hospital, Bangkok, Thailand, from July 2004 to June 2005 were reviewed. A total of 263 medical records were reviewed in this study. There were 17 positive cases of the overall 263. The diagnostic test results were negative in 246 cases (93.5%) and positive in 17 (6.5%). Screening for the urine pregnancy among these migrant workers can help decrease the improper antenatal care.

    Single-embryo image assessment involves a high degree of inaccuracy because of the imprecise labelling of the transferred embryo images. In this study, we considered the entire transfer cycle to predict the implantation potential of embryos, and propose a novel algorithm based on a combination of local binary pattern texture feature and Adaboost classifiers to predict pregnancy rate. The first step of the proposed method was to extract the features of the embryo images using the local binary pattern operator. After this, multiple embryo images in a transfer cycle were considered as one entity, and the pregnancy rate was predicted using three classifiers: the Real Adaboost, Gentle Adaboost, and Modest Adaboost. Finally, the pregnancy rate was determined via the majority vote rule based on classification results of the three Adaboost classifiers. The proposed algorithm was verified to have a good predictive performance and may assist the embryologist and clinician to select embryos to transfer and in turn improve pregnancy rate.

    2011-05-01

    This experimental prospective quasi-randomized study examining the impact of a medical clowning encounter after embryo transfer (ET) after in vitro fertilization (IVF) found that the pregnancy rate in the intervention group was 36.4%, compared with 20.2% in the control group (adjusted odds ratio, 2.67; 95% confidence interval, 1.36-5.24). Medical clowning as an adjunct to IVF-ET may have a beneficial effect on pregnancy rates and deserves further investigation.

    Kerr, David C R; Leve, Leslie D; Chamberlain, Patricia

    2009-06-01

    Preventing adolescent pregnancy is a national research priority that has had limited success. In the present study, the authors examined whether Multidimensional Treatment Foster Care (MTFC) relative to intervention services as usual (group care [GC]) decreased pregnancy rates among juvenile justice girls mandated to out-of-home care. Girls (13-17 years of age) with histories of criminal referrals (Mdn = 10) were randomly assigned to MTFC (n = 81) or GC (n = 85) as part of 2 randomized controlled trials. Pregnancy histories were assessed from baseline through 24 months. Fewer postbaseline pregnancies were reported for MTFC girls (26.9%) than for GC girls (46.9%)--an effect that remained significant after controlling for baseline criminal referrals, pregnancy history, and sexual activity. MTFC has previously been shown to decrease arrest and lock-up rates. The present findings support the long-term preventive effects of MTFC on adolescent girls' pregnancy rates. Findings are consistent with the notion that programs that target delinquency by impacting general risk behavior pathways and contexts may more successfully prevent teen pregnancy than those that directly target sexual behaviors.

    Background Alcohol and substance use is a major health challenge in Turkey, as it is worldwide. Recently, there has been a rapid increase in the number of females using substances and although usage tends to reduce during pregnancy, it is of critical importance to determine its exact level as substance use negatively impacts on the health of both the mother and infant. Aim The aim of the present study was to investigate the frequency of smoking, alcohol, and substance use, and quitting rates during pregnancy. Method This study was conducted on pregnant females in Sakarya, Turkey. A total of 1,082 consecutively presenting females who agreed to participate in the study were evaluated. The study team prepared a sociodemographic data form and adapted the “Introduction” section, derived from the Addiction Profile Index, to cover substance use during pregnancy. Results The substances most frequently used by pregnant females in their previous pregnancies and current pregnancies were cigarettes/tobacco products (11% and 11.8%, respectively), alcohol (0.6% and 0.4%, respectively), and rarely, synthetic cannabinoids (0.3% and 0.2%, respectively). Daily tobacco smokers continued to smoke during pregnancy, with a rate of 42.5%. Based on research into predictors of smoking (cigarettes) in pregnancy, a correlation was found between lifetime smoking and smoking during a previous pregnancy. A similar link was found with respect to alcohol. Conclusion Cigarettes are the most frequently used substance in pregnancy, and to a lesser extent, alcohol and synthetic cannabinoids, also considered to be risky substances. A high incidence of smoking regularly during pregnancy was found in daily smokers. It is recommended that physicians should sensitively ask pregnant females presenting at clinics about all forms of substance use, including alcohol and synthetic cannabinoids, and to include such questions in their routine enquiries.

    The objectives of this study were to evaluate the prevalence of depressive symptoms in the third trimester of pregnancy and at 3 months postpartum and to prospectively identify risk factors associated with elevated depressive symptoms during pregnancy and with postpartum onset. About 364 women attending antenatal clinics or at the time of their ultrasound were recruited and completed questionnaires in pregnancy and 226 returned their questionnaires at 3 months postpartum. Depressed mood was assessed by the Edinburgh Postnatal Depression Scale (EPDS; score of ≥ 10). The rate of depressed mood during pregnancy was 28.3% and 16.4% at 3 months postpartum. Among women with postpartum depressed mood, 6.6% were new postpartum cases. In the present study, belonging to a non-Caucasian ethnic group, a history of emotional problems (e.g. anxiety and depression) or of sexual abuse, comorbid anxiety, higher anxiety sensitivity and having experienced stressful events were associated with elevated depressed mood during pregnancy. Four risk factors emerged as predictors of new onset elevated depressed mood at 3 months postpartum: higher depressive symptomatology during pregnancy, a history of emotional problems, lower social support during pregnancy and a delivery that was more difficult than expected. The importance of identifying women at risk of depressed mood early in pregnancy and clinical implications are discussed.

    OBJECTIVE: To study trends in multiple pregnancies not explained by changes in maternal age and parity patterns. DESIGN: Trends in population based figures for multiple pregnancies in Denmark studied from complete national records on parity history and vital status. POPULATION: 497,979 Danish women and 803,019 pregnancies, 1980-94. MAIN OUTCOME MEASURES: National rates of multiple pregnancies, infant mortality, and stillbirths controlled for maternal age and parity. Special emphasis on primiparous women > or = 30 years of age, who are most likely to undergo fertility treatment. RESULTS: The national incidence of multiple pregnancies increased 1.7-fold during 1980-94, the increase primarily in 1989-94 and almost exclusively in primiparous women aged > or = 30 years, for whom the adjusted population based twinning rate increased 2.7-fold and the triplet rate 9.1-fold. During 1989-94, the adjusted yearly increase in multiple pregnancies for these women was 19% (95% confidence interval 16% to 21%) and in dizygotic twin pregnancies 25% (21% to 28%). The proportion of multiple births among infant deaths in primiparous women > or = 30 years increased from 11.5% to 26.9% during the study period. The total infant mortality, however, did not increase for these women because of a simultaneous significant decrease in infant mortality among singletons. CONCLUSIONS: A relatively small group of women has drastically changed the overall national rates of multiple pregnancies. The introduction of new treatments to enhance fertility has probably caused these changes and has also affected the otherwise decreasing trend in infant mortality. Consequently, the resources, both economical and otherwise, associated with these treatments go well beyond those invested in specific fertility enhancing treatments. PMID:9080993

    Maternal weight gain and pattern of weight gain during pregnancy influence the ultimate outcome of pregnancy. Pregravid body mass index (BMI), maternal dietary intake, maternal height and age all determine the weight gain during pregnancy. The study was taken up with an objective to observe maternal weight gain and its pattern in pregnancy in women from an upper income group and to find out their association with pregnancy outcome. 180 normal primiparous pregnant Indian women (20-35 years) from an upper income group were recruited between the 10th and 14th weeks of pregnancy and were followed up throughout their pregnancy to record total and trimester-wise weight gain. Neonatal birth weights were recorded. The results showed that mothers with high pregravid BMI gained more weight during pregnancy than the recommended weight gain; in addition, weight gain in the first trimester was significantly correlated with birth weight of the neonates (P = 0.019). Significant correlation was found between weight gain in the third trimester and birth weight of the neonate irrespective of maternal BMI. The rate of weight gain was significantly correlated with neonatal birth weights irrespective of maternal pregravid BMI (P = 0.022) and as per its categories (P = 0.027). Thus, overall it can be concluded that adequate maternal nutrition before and during pregnancy is important for adequate weight gain by the mother and can result in better outcome of pregnancy. The rate of weight gain is also an important contributing factor.

    In a population of about 300,000 Northern California women aged 15--44, the age-adjusted incidence of ectopic pregnancy rose from 55.5 to 84.2/100,000 women, 1972--1978. The ratio of ectopics to 1,000 deliveries-plus-spontaneous abortions rose from 9.4 to 14.8. The change occurred mainly in women under age 30, and was observed in seven of the eight hospitals in the area. There was no alteration in the frequency of hospitalized pelvic inflammatory disease (PID); salpingitis decreased over the years studied; and tubal sterilization events remained constant at around 0.9 per cent per year of women aged 15--44.

    Background: Tubal factor infertility is one of the main causes of female infertility. Although its sensitivity is low, hysterosalpingography (HSG) is remains the first-line method for evaluating tubal patency. Aims: To compare pregnancy rates in patients with HSG proven proximal or distal unilateral tubal occlusion, and unexplained infertility undergoing both controlled ovarian stimulation (COS) and intrauterine insemination (IUI). Study Design: Case control study. Methods: In total, 237 patients undergoing ovulation induction (OI) with gonadotropins and IUI were divided into two groups and evaluated. Study group consisted 59 patients with HSG proven unilateral tubal pathology, and 178 patients with unexplained infertility taken as control subjects. Cumulative pregnancy rate was the primary endpoint. Results: Cumulative pregnancy rates after three cycles of OI and IUI were 15.25% in study group and 20.79% in control group. Pregnancy rates between two groups were not statistically significant. Although, pregnancy rates in patients with proximal tubal occlusion (21.8%) were higher than in those with distal tubal occlusion (7.4%), the difference was not statistically significant. Conclusion: Our study data shows that, regardless of the HCG proven occlusion area, COS and IUI might be a preferred treatment modality in patient with unilateral tubal occlusion. PMID:28251025

    PubMed

    Rome, Ellen

    2015-11-01

    Long-acting reversible contraceptives (LARCs) are safe for use in adolescents and do not rely on compliance or adherence for effectiveness. Continuation rates are higher and pregnancy rates are lower for adolescent users of LARCs compared with short-acting methods such as oral contraceptives. Similarly, repeat pregnancy rates are lower when LARCs are used compared with other forms of contraception. Myths and misconceptions about LARCs and other contraceptives remain a barrier to their use. Health care providers are in a unique position to provide confidential care to adolescents, and should provide education to them about the various contraceptive options, especially LARCs.

    Allison, Colelia

    As the need for quality online courses increase in demand, the acceptance of technology and completion rates become the focus of higher education. The purpose of this non-experimental, mixed method study was to examine the relationship between the university students' perceptions and acceptance of technology and learner completion rates with respect to the development of online courses. This study involved 61 participants from two universities regarding their perceived usefulness (PU) of technology, intent to use technology, and intent to complete a course. Two research questions were examined regarding student perceptions regarding technology employed in an online course and the relationship, if any, between technology acceptance and completion of an online university course. The technology acceptance model (TAM) was used to collect data on the usefulness of course activities and student intent to complete the course. An open-ended questionnaire was administered to collect information concerning student perceptions of course activities. Quantitative data was analyzed using SPSS and Qualtrics, which indicated there was not a significant relationship between technology acceptance and course completion (p = .154). Qualitative data were examined by pattern matching to create a concept map of the theoretical patterns between constructs. Pattern matching revealed many students favored the use of the Internet over Canvas. Furthermore, data showed students enrolled in online courses because of the flexibility and found the multimedia used in the courses as helpful in course completion. Insight was investigated to offer reasons and decisions concerning choice that were made by the students. Future recommendations are to expand mixed methods studies of technology acceptance in various disciplines to gain a better understanding of student perceptions of technology uses, intent to use, and course completion.

    2012-01-01

    To determine whether glucocorticoids affect the function of the bovine corpus luteum (CL) during the estrous cycle and early pregnancy, we examined the effects of exogenous cortisol or reduced endogenous cortisol on the secretion of progesterone (P4) and on pregnancy rate. In preliminary experiments, doses of cortisol and metyrapone (an inhibitor of cortisol synthesis) were established (n=33). Cortisol in effective doses of 10 mg blocked tumor necrosis factor-induced prostaglandin F(2α) secretion as measured by its metabolite (PGFM) concentrations in the blood. Metyrapone in effective doses of 500 mg increased the P4 concentration. Thus, both reagents were then intravaginally applied in the chosen doses daily from Day 15 to 18 after estrus (Day 0) in noninseminated heifers (n=18) or after artificial insemination (n=36). Pregnancy was confirmed by transrectal ultrasonography between Days 28-30 after insemination. Plasma concentrations of P4 were lower in cortisol-treated heifers than in control heifers on Days 17 and 18 of the estrous cycle (P<0.05). However, the interestrus intervals were not different between control and cortisol-treated animals (P>0.05). Moreover, metyrapone increased P4 and prolonged the CL lifespan in comparison to control animals (P<0.05). Interestingly, in inseminated heifers, cortisol increased the pregnancy rate (75%) compared with control animals (58%), whereas metyrapone reduced the pregnancy rate to 16.7% (P<0.05). The overall results suggest that cortisol, depending on the physiological status of heifers (pregnant vs. nonpregnant), modulates CL function by influencing P4 secretion. Cortisol may have a positive influence on CL function during early pregnancy, leading to support of embryo implantation and resulting in higher rates of pregnancy in heifers.

    Asian ethnicity has been associated with decreased pregnancy outcomes in patients undergoing IVF. The objective of this study was to determine if a difference exists in pregnancy rates between Asian and Caucasian patients undergoing intrauterine insemination (IUI). A retrospective cohort of Asian and Caucasian patients treated with IUI between December 2002 and 2006 was analysed, including 2327 IUI cycles among 814 patients. Baseline characteristics were similar between Asian and Caucasian women. A significantly greater proportion of Asians (43.9%) presented for treatment after more than 2 years of infertility compared with Caucasians (24.6%) (P < 0.0001). Unadjusted analysis showed a trend towards decreased pregnancy rates associated with Asian ethnicity (odds ratio (OR) 0.71, 95% CI 0.50-1.01, not significant). Age, stimulation protocol, differences in gravity and parity, and duration of infertility did not account for this difference (adjusted OR 0.68, 95% CI 0.47-0.98, P = 0.039). Asian ethnicity is associated with lower pregnancy rates in IUI treatment. The increased duration of infertility in Asians does not explain the reduced pregnancy rates.

    To evaluate the influence of female age and cause of infertility on the outcome of controlled ovarian hyperstimulation (COH) and intrauterine insemination (IUI), we studied 2717 COH cycles in 1035 subfertile couples. The cumulative clinical pregnancy rates were 39% and 58% after three and six COH cycles, respectively. The cumulative pregnancy rate significantly decreased with maternal age and differed by cause of infertility. The cumulative pregnancy rate continued to increase with an increase in COH cycle number up to the third, or forth cycle, in patients with mechanical and combined infertility, respectively, and in up to the second cycle in patients aged 40 years or more. These findings provide treatment guidelines for clinicians in determining the likelihood of treatment success and the point at which to proceed to the next treatment strategy.

    1984-02-01

    Seventy-six Brahman cows and first-calf heifers were assigned to one of two groups: 1) normal suckling (34 cows) or 2) twice-daily suckling (45 minutes of suckling each time; 42 cows). Twice-daily suckling was carried out from 30 days postcalving until weaning (seven months). All animals were maintained under artificial insemination for a four-month breeding period. Mean pregnancy rate was 63.06 +/- 0.06% and was influenced by suckling group (P<0.01) and number of parturitions (P<0.05). The pregnancy rates were 33% higher in twice-daily suckled cows. Forty-four percent of the first calf heifers in the twice-daily suckling group became pregnant compared to 9% in the normal suckling group (P<0.01). Twice-daily suckling improved pregnancy rate without depressing preweaning calf performance.

    The overall aim of this research was to improve fertility of cattle inseminated with sexed spermatozoa by improving sperm sorting procedures. Six field trials were conducted in which 4,264 heifers were inseminated into the uterine body with cryopreserved sexed or unsexed control spermatozoa. Pregnancy or calving rates with doses of 2 x 10(6) sexed spermatozoa ranged from 32 to 51%; these averaged 69% of the pregnancy rates with 20 x 10(6) unsexed, control spermatozoa (range 53 to 79% of controls). Fertility of sexed spermatozoa was especially low on farms where control fertility was low. Accuracy of sexing ranged from 86 to 91%. Laser power of 150 mW for interrogating spermatozoa did not result in lower pregnancy rates (43%) than when power was decreased as much as possible for a particular sorting batch (50 to 130 mW) to still achieve sexing accuracy (38% pregnant). Addition of catalase to fluids containing spermatozoa was beneficial when thawed spermatozoa were incubated in vitro for 2 h but had no effect on pregnancy rates. There also was no effect on pregnancy rates between two concentrations of Hoechst 33342 for staining spermatozoa. Freezing 2 x 10(6) sexed spermatozoa at 20 x 10(6)/ml resulted in a slightly higher rate of pregnancy (P < 0.05) than at 10 x 10(6)/ml. The information obtained in these trials, along with other improvements, notably lowering pressure in the sorting system from 50 to 40 psi, has been used to improve procedures for sexing spermatozoa commercially.

    The stochastic optimization method ALOPEX IV has been successfully applied to the problem of detecting possible changes in the maternal heart rate kinetics during pregnancy. For this reason, maternal heart rate data were recorded before, during and after gestation, during sessions of exercises of constant mild intensity; ALOPEX IV stochastic optimization was used to calculate the parameter values that optimally fit a dynamical systems model to the experimental data. The results not only demonstrate the effectiveness of ALOPEX IV stochastic optimization, but also have important implications in the area of exercise physiology, as they reveal important changes in the maternal cardiovascular dynamics, as a result of pregnancy.

    Achieving high vaccination rates of health care personnel (HCP) is critical in preventing influenza transmission from HCP to patients and from patients to HCP; however, acceptance rates remain low. In 2013, New York State adopted the flu mask regulation, requiring unvaccinated HCP to wear a mask when in areas where patients are present. The purpose of this study assessed the impact of the flu mask regulation on the HCP influenza vaccination rate. A 13-question survey was distributed electronically and manually to the HCP to examine their knowledge of influenza transmission and the influenza vaccine and their personal vaccine acceptance history and perception about the use of the mask while working if not vaccinated. There were 1,905 respondents; 87% accepted the influenza vaccine, and 63% were first-time recipients who agreed the regulation influenced their vaccination decision. Of the respondents who declined the vaccine, 72% acknowledge HCP are at risk for transmitting influenza to patients, and 56% reported they did not receive enough information to make an educated decision. The flu mask protocol may have influenced HCP's choice to be vaccinated versus wearing a mask. The study findings supported that HCP may not have adequate knowledge on the morbidity and mortality associated with influenza. Regulatory agencies need to consider an alternative approach to increase HCP vaccination, such as mandating the influenza vaccine for HCP.

    Purpose Identifying co-occurring community risk factors, specific to rural communities, may suggest new strategies and partnerships for addressing sexual health issues among rural youth. We conducted an ecological analysis to identify the county-level correlates of pregnancy and chlamydia rates among adolescents in rural (nonmetropolitan) counties in Minnesota. Methods Pregnancy and chlamydia infection rates among 15–19 year-old females were compared across Minnesota’s 87 counties, stratified by rural/urban designations. Regression models for rural counties (n=66) in Minnesota were developed based on publicly available, county-level information on behaviors and risk exposures to identify associations with teen pregnancy and chlamydia rates in rural settings. Findings Adolescent pregnancy rates were higher in rural counties than in urban counties. Among rural counties, factors independently associated with elevated county-level rates of teen pregnancy included inconsistent contraceptive use by 12th-grade males, fewer 12th graders reporting feeling safe in their neighborhoods, more 9th graders reporting feeling overweight, fewer 12th graders reporting 30 min of physical activity daily, high county rates of single parenthood, and higher age-adjusted mortality (P < .05 for all associations). Factors associated with higher county level rates of chlamydia among rural counties were inconsistent condom use reported by 12th-grade males, more 12th graders reporting feeling overweight, and more 12th graders skipping school in the past month because they felt unsafe. Conclusions This ecologic analysis suggests that programmatic approaches focusing on behavior change among male adolescents, self-esteem, and community health and safety may be complementary to interventions addressing teen sexual health in rural areas; such approaches warrant further study.

    The relationship between laboratory and field ratings was investigated for six different appetizers, including four ready-to-reconstitute mixes and two ready-to-eat munches. Liking ratings on a 5-point hedonic scale were obtained from an Indian Army field study at base level as well as at an altitude of 11,500 ft above sea level and for the same appetizers in the laboratory. The field trials of the six products were conducted in two phases and results revealed that the products were more acceptable at altitude, with increased liking scores as compared to base level. Subjective ratings for hunger revealed that at altitude, appetizer consumption had stimulated the appetite of the soldiers. The ability of laboratory ratings to predict acceptability of foods consumed under realistic conditions appears to depend on the convenience of the appetizer as well as the environmental conditions and the psycho-physiological status of the participants. The appetizers received higher ratings at altitude because of the pungent and spicy nature of appetizer mixes as compared with base field and laboratory conditions. However, for all the appetizers the pungent and sweet taste of the appetizer munches was highly preferred.

    Objective. To compare pregnancy rate after controlled ovarian hyperstimulation and intrauterine insemination (COH-IUI) with no treatment in patients with endometriosis-associated infertility treated with laparoscopy. Design. A clinical cohort study. Setting. University-level tertiary care center. Patients. 238 women with various stages of endometriosis after laparoscopic treatment. Interventions. Either COH-IUI or follow-up for 12 months. Main Outcome Measures. The primary outcome measures were clinical pregnancy and live birth rate. Predictive factors evaluated were female age, maternal BMI, and duration of infertility. Results. The pregnancy rate attained after the integrated laparoscopy–COH-IUI approach was 53.4%, while it was significantly lower (38.5%) in the control group. Similarly, a significant difference was observed in live births (48.3% versus 34.2%). Patients with severe endometriosis were less likely to achieve pregnancy (38%) and live birth (35%) than their counterparts with milder forms (57% and 53%). Conclusions. In patients with endometriosis-based infertility, surgery followed by COH-IUI is more effective than surgery alone. PMID:26247014

  2. Effect of flunixin meglumine and carprofen on pregnancy rates in dairy cattle.

    2010-11-01

    Embryonic losses contribute considerably to low pregnancy rates. Between d 8 and 17 after breeding, the conceptus secretes interferon-τ as a mechanism for maternal recognition of pregnancy and maintenance of the corpus luteum. Nonsteroidal antiinflammatory drugs inhibit the synthesis of prostaglandin F(2α) by suppressing the enzyme cyclooxygenase. Flunixin meglumine (FM) has been demonstrated to delay luteolysis and to support embryonic survival. The objective of this study was to evaluate the effect of FM and carprofen on conception rates in dairy heifers and cows, respectively. In experiment 1, the effect of FM on pregnancy rates and progesterone concentrations in dairy heifers was tested. A total of 391 heifers were randomly assigned to 1 of 2 groups. Heifers in the treatment group (n=197) received 2.2 mg of FM i.m./kg of body weight twice on d 14/15 and 15/16 after insemination, whereas heifers in the control group (n=194) remained untreated. Blood samples from 388 heifers were taken on d 14/15 and 21/22 after artificial insemination and analyzed for progesterone. Pregnancy rates were 58.2 and 54.8% for the control and treatment groups, respectively. Mean progesterone concentrations were not affected by treatment and number of artificial insemination service (first or second artificial insemination service), but were affected by time and time × pregnancy status. In experiment 2, the objective was to verify the effects of carprofen, a longer acting nonsteroidal antiinflammatory drug and to evaluate its effect on conception rate to first service in dairy cows. A total of 380 cows were randomly assigned to 1 of 2 treatment groups. Cows in the treatment group (n=194) received 1.4 mg of carprofen s.c./kg of body weight on d 15 after insemination, whereas cows in the control group (n=186) remained untreated. Pregnancy was diagnosed between d 40 and 47 after insemination. Conception rates to first service were 35.5 and 33.0% in the control and treatment groups

    Despite growing research emphasis on understanding the health effects of ethnic discrimination, little work has focused on how such exposures may influence a woman's biology and health during pregnancy. Understanding such effects is important given evidence that maternal stress experience in pregnancy can have long term effects on offspring health. Here we present data evaluating the relationship between perceived discrimination, self-rated health, and the stress hormone cortisol measured in late pregnancy among a diverse sample of women living in Auckland, New Zealand (N = 55). We also evaluated possible intergenerational impacts of maternal discrimination on stress reactivity in a subset of offspring (N = 19). Pregnant women were recruited from two antenatal care clinics in Auckland. Women were met in their homes between 34 and 36 weeks gestation, during which time a prenatal stress questionnaire was administered and saliva samples (morning and evening from two days) were obtained. Offspring cortisol reactivity was assessed at the standard six week postnatal vaccination visit. We found that 34% of women reported having experienced ethnic discrimination, with minority and immigrant women being more likely to report being angry or upset in response to discrimination experience compared with NZ-born women of European descent. Women reporting discrimination experience had worse self-rated health, higher evening cortisol and gave birth to infants with higher cortisol reactivity, all independent of ethnicity and material deprivation. These findings suggest that discrimination experience can have biological impacts in pregnancy and across generations, potentially contributing to the ethnic gradient in health.

    The purpose of this study was to study the determinants of self rated health in the low-risk pregnant women of Melaka Tengah in Malaysia. A total of 387 subjects were analysed. The role of mental health, psychosocial stressors, support from husband, coping skills, socio-economic status and pregnancy characteristics in determining self- rated health were studied. Health items were taken from the Duke Health Profile. Bad obstetric history, poor mental health, stress from the family were found to be significantly associated with poor self - rated health whereas good support from the husband was related to good self - rated health.

  5. Feasibility and acceptability of a midwife-led intervention programme called 'Eat Well Keep Active' to encourage a healthy lifestyle in pregnancy

    PubMed Central

    2012-01-01

    Background Eating a diet that is high in fat and sugar and having a sedentary lifestyle during pregnancy is understood to increase the risk of excessive gestational weight gain and obesity following the birth of the baby. However, there are no clinical guidelines in the UK on what is considered to be appropriate gestational weight gain. Indeed, clinical recommendations discourage the routine re-weighing of pregnant women, stating instead that women should be advised regarding their diet and activity levels, in order to prevent excessive weight gain. Pregnancy is seen as a time when many women may have an increased motivation to improve their lifestyle behaviours for the benefit of the fetus. However, it is evident that many women have difficulty in both maintaining a healthy balanced diet and remaining active through pregnancy. It would seem that midwives may be ideally placed to assist women to make and maintain healthier lifestyle choices during pregnancy. Methods/design This study will look at the feasibility and acceptability of a newly devised intervention programme called 'Eat Well Keep Active'. Participants will complete a questionnaire prior to the programme to obtain baseline data on food frequency, physical activity and to gauge their perception of personal ability to improve/maintain healthy lifestyle. The programme comprises client centred techniques; motivational interviewing and goal setting delivered early in pregnancy (12-16 weeks) with the aim of supporting a healthy well balanced diet and either continuing or commencing appropriate levels of physical activity. Participants will then be followed up six weeks following the intervention with a one-to-one interview, and a further brief questionnaire. The interview will provide preliminary data regarding perceived effectiveness and acceptability of the 'Eat Well Keep Active' programme whilst the questionnaire will provide data regarding changes in the confidence of participants to lead a healthy

    The measurement of operational acceptability is important for the development, implementation, and evolution of air traffic management decision support tools. The Controller Acceptance Rating Scale was developed at NASA Ames Research Center for the development and evaluation of the Passive Final Approach Spacing Tool. CARS was modeled after a well-known pilot evaluation rating instrument, the Cooper-Harper Scale, and has since been used in the evaluation of the User Request Evaluation Tool, developed by MITRE's Center for Advanced Aviation System Development. In this paper, we provide a discussion of the development of CARS and an analysis of the empirical data collected with CARS to examine construct validity. Results of intraclass correlations indicated statistically significant reliability for the CARS. From the subjective workload data that were collected in conjunction with the CARS, it appears that the expected set of workload attributes was correlated with the CARS. As expected, the analysis also showed that CARS was a sensitive indicator of the impact of decision support tools on controller operations. Suggestions for future CARS development and its improvement are also provided.

    The aim of this study was to investigate the effects of mastitis on CL development and function and pregnancy rate in buffaloes. Sixty-six buffaloes (Bubalus bubalus) reared in a commercial farm at El-Beheira governorate, north of Egypt were used in this study. According to the visual observation of milk, physical examination of the udder and actual somatic cell count in milk, buffalo cows were divided into three groups: without mastitis (W), n = 23; subclinical mastitis (SC), n = 18; and clinical mastitis (C), n = 25. All buffalo cows were synchronized by double dose of PGF2α (11-day interval) and inseminated by frozen-thawed semen of fertile bull. Mean CL diameter was ultrasonically examined on Days 5, 9, 12, 16, 21, and 25 after artificial insemination (AI). Blood samples were taken on the days of ultrasonography for progesterone (P4) assay. Results indicated that pregnancy rates were lower (P < 0.05) in C (28.00%) and SC (55.56%) compared with W (69.57%) on Day 25 after first AI. Pregnancy rates reduced to 60.87%, 44.45%, and 16.00% in W, SC, and C, respectively, at Day 45 after insemination. Thus, the embryonic loss was 8.7%, 11.11%, and 12.00 % in W, SC, and C cows, respectively. Pregnancy rates decreased between 44.32% and 50.51% when mastitis occurred during Day -15 before to Day +30 after AI, compared with 59.22% in the uninfected cows. The diameter of CL was greater (P < 0.05) in W than SC and C cows starting at Day 9 postbreeding onward. Likewise, P4 concentrations on Days 9 through 25 after AI were greater (P < 0.05) in W cows as compared to SC and C cows. Positive correlations (P < 0.01) were found on Days 5, 9, 12, 16, 21, and 25 after AI between CL diameter and P4 concentrations. Similar trend was found among CL diameter, P4 concentrations, and pregnancy rate. Accordingly, incidence of mastitis revealed suppression to both CL diameter and function leading to significant reduction in pregnancy outcome of buffalo cows.

    It has been shown that short-term direct interaction between maternal and fetal heart rates may take place and that this interaction is affected by the rate of maternal respiration. The aim of this study was to determine the effect of maternal aerobic exercise during pregnancy on the occurrence of fetal-maternal heart rate synchronization. Methods In 40 pregnant women at the 36th week of gestation, 21 of whom exercised regularly, we acquired 18 min. RR interval time series obtained simultaneously in the mothers and their fetuses from magnetocardiographic recordings. The time series of the two groups were examined with respect to their heart rate variability, the maternal respiratory rate and the presence of synchronization epochs as determined on the basis of synchrograms. Surrogate data were used to assess whether the occurrence of synchronization was due to chance. Results In the original data, we found synchronization occurred less often in pregnancies in which the mothers had exercised regularly. These subjects also displayed higher combined fetal-maternal heart rate variability and lower maternal respiratory rates. Analysis of the surrogate data showed shorter epochs of synchronization and a lack of the phase coordination found between maternal and fetal beat timing in the original data. Conclusion The results suggest that fetal-maternal heart rate coupling is present but generally weak. Maternal exercise has a damping effect on its occurrence, most likely due to an increase in beat-to-beat differences, higher vagal tone and slower breathing rates. PMID:25162592

    Background: Human chorionic gonadotropin (hCG) as the most important factor to controlled implantation is one of the early embryonic signals in primates that is secreted by the embryo before its implantation. This study was designed to assess the effects of intrauterine injection of hCG before the embryo transfer in an in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycle on pregnancy rate in infertile patients. Materials and Methods: This randomized study was done on 100 infertile patients in two groups: intervention group received injection of 700 IU of intrauterine hCG 10 min before embryo transfer and control group did not receive hCG. The pregnancy rate was tested 2 weeks after embryo transfer, and if the pregnancy test was positive, a transvaginal ultrasound was performed 3 weeks later to search for signs of pregnancy, such as the presence of a gestational sac, embryo, and fetal heart rate, and confirmed as successful pregnancy. Results: Pregnancy test was positive in 13 (28.6%) of 46 patients in hCG group and in control group was positive in 6 (12.5%) of 48 patients. The pregnancy rate between hCG group and control group was not significantly different (P = 0.54). The pregnancy rate in hCG group with IVF fertilization was 20.8% and in their controls was 7.4% (P = 0.51). The pregnancy rate in hCG group with ICSI fertilization was 36.4% and in their controls was 19% (P = 0.16). Conclusion: The intrauterine injection of 700 IU of hCG before embryo transfer improved pregnancy rate compared to control group but was not significantly different.

    Randomized clinical trials (RCTs) demonstrated the equal efficacy of urinary human chorionic gonadotropin (uhCG) and recombinant hCG (rhCG) products in in vitro fertilisation (IVF). However, limitations inherent with RCTs necessitate the reinforcement of RCT results in real-life. We retrospectively analyzed pregnancies after treatment with rhCG and uhCG products (n = 391, and 96, resp.). We found that laboratory-verified pregnancy occurred more frequently in rhCG patients than in those on uhCG (43% versus 30%, P = 0.02). The association remains significant (P = 0.002) after its adjustment for clinical characteristics. The prevalence of laboratory-verified pregnancies was higher with GnRH agonist use (P = 0.012) and BMI under 30 kg/m(2) (P = 0.053) while decreased the age (P = 0.014) and the number of previous failed attempts (P = 0.08). Similar (but not significant) trends were observed with rates of pregnancy filled the 24th week. These results reinforce RCTs supporting the notion that rhCG is more efficient as uhCG during IVF.

  11. Improving access to emergency contraception under the Scottish Sexual Health Strategy: can rates of unintended pregnancy be reduced?

    McGowan, James G

    2013-09-01

    Unintended pregnancy is a global sexual health problem. Outcomes of unintended pregnancy include unwanted childbirth and abortion, which may be associated with negative physical and psychosocial health implications for women. In Scotland, the Scottish Sexual Health Strategy has the stated goal of improving the sexual health of the people of Scotland. One aim of the Strategy is to reduce rates of unintended pregnancy and one policy designed to achieve this is 'widening access to emergency contraception'. This paper examines the success of this policy with reference to the implicit link it makes between expanding access to emergency contraception and increasing its effective use, aiming thereby to reduce rates of unintended pregnancy. Since there is evidence that previous policies and strategies expanding access to emergency contraception have failed to reduce such rates, alternative approaches to achieve a reduction in unintended pregnancies are discussed.

    Introduction: Male infertility factor is defined if the total number of motile spermatozoa (TMSC) < 20 × 106/ejaculated, and unexplained infertility if spermiogram is normal with normal female factor. The aim: of this study was to determine the predictive value of TMSC for spontaneous pregnancy (ST) and pregnancy after treatment with intrauterine insemination (IUI) in couples with male factor and unexplained infertility. What is known already: According to the WHO qualification system abnormal spermiogram can be diagnosed as oligozoospermia (O), asthenozoospermia (A), teratozoospermia (T) or combination (O+A+T) and azoospermia (A). Although this classification indicates the accuracy of findings its relevance for prognosis in infertile couple and the choice of treatment is questionable. Materials and Methods: The study included 98 couples with male infertility factor (bad spermiogram) and couples with normospermia and normal female factor (unexplained infertility). Testing group is randomized at: group (A) with TMSC> 3,106 / ejaculate and a spontaneous pregnancy, group (B) with TMSCl <3 x 106 / ejaculate and pregnancy after IUI, plus couples who have not achieved SP with TMSC> 3 x 106 / ejaculate and couples who have not achieved pregnancy. Main results: From a total of 98 pairs of men’s and unexplained infertility, 42 of them (42.8%) achieved spontaneous pregnancy, while 56 (57.2%) pairs did not achieve spontaneous pregnancy. TMSC was significantly higher (42.4 ± 28.4 vs. 26.2 ± 24, p <0.05) in the group A compared to group B. Couples with TMSC 1-5 × 106 ejaculate had significantly lower (9.8% vs. 22.2%, p <0.0001) rate of spontaneous pregnancy in comparison to couples after IUI treatment. Couples with unexplained infertility had significantly higher (56.8% vs. 29.9%, p <0.01) spontaneous pregnancy rate compared to couples after IUI treatment. Infertile couples had significant pregnancy rate with TMSC 5-10 x 106 / ejaculate (OR = 1.45, 95% CI:1.26-1.78, <0

    A successful outcome after artificial insemination with cooled semen is dependent on many factors, the sperm quality of the ejaculate being one. Previous studies have shown that spermatozoa with good motility, normal morphology, and good chromatin integrity can be selected by means of colloid centrifugation, particularly single layer centrifugation (SLC) using species-specific colloids. The purpose of the present study was to conduct an insemination trial with spermatozoa from "normal" ejaculates, i.e., from stallions with no known fertility problem, to determine whether the improvements in sperm quality seen in SLC-selected sperm samples compared with uncentrifuged controls in laboratory tests are reflected in an increased pregnancy rate after artificial insemination. In a multicentre study, SLC-selected sperm samples and uncentrifuged controls from eight stallions were inseminated into approximately 10 mares per treatment per stallion. Ultrasound examination was carried out approximately 16 days after insemination to detect an embryonic vesicle. The pregnancy rates per cycle were 45% for controls and 69% for SLC-selected sperm samples, which is statistically significant (P < 0.0018). Thus, the improvement in sperm quality reported previously for SLC-selected sperm samples is associated with an increase in pregnancy rate, even for ejaculates from stallions with no known fertility problem.

    An ultrasound assessment of follicle turnover following two different protocols for synchronization of oestrus and ovulation, as well as an assessment of achieved synchronization between ovulation and AI and conception rates in nulliparous and pluriparous buffaloes were carried out during months of increasing day length. Nulliparous buffaloes (n = 30) were subjected only to Ovsynch protocol whereas pluriparous buffaloes (n = 31) were assigned to Ovsynch (n = 14) or to PRID-pregnant mare serum gonadotrophin (PMSG) (n = 17) protocol according to the presence of functional CL confirming cyclic and acyclic conditions. Ultrasound examination of ovarian follicular dynamics at critical days in the course of synchronization treatments was employed to monitor the fate of the largest available follicles at the beginning of treatments. Such available dominant follicle would persist throughout the protocol as ovulating follicle (no-follicle shift) or would regress giving way to a new follicle to become dominant and ovulate (follicle shift). Furthermore, ultrasound monitoring would determine the degree of synchronization of ovulation and final outcome represented by pregnancy rates. Pregnancy rate following Ovsynch protocol was 40% (12/30) and 42.8% (6/14) in nulliparous and pluriparous buffaloes respectively (p = 0.8575). Most ovulations were synchronized and recorded at AI and the following day in nulliparous (24/30; 80%) and pluriparous (12/14; 85.7%) buffaloes respectively (p = 1.000). A follicle shift was recorded in 14 of 30 (46.6%) and 11 of 14 (78.5%) in nulliparous and pluriparous buffaloes respectively (p = 0.0466). Among established pregnancies: eight derived from follicle shift (66.6%) and four from no-follicle shift (33.3%) in nulliparous buffaloes, p = 0.0729 whereas in pluriparous buffaloes five (83.3%) derived from follicle shift and one from no-follicle shift (16.6%), p = 0.6154. Collectively, from 18 pregnancies in nulliparous and pluriparous buffaloes

    Three studies were conducted to test the hypothesis that dietary spray-dried plasma (SDP) might improve pregnancy rate by ameliorating inflammation, using mice in an experimental model that produces a low pregnancy rate. Mated female mice (C57BL/6 strain) were purchased and shipped from a vendor (Bar Harbor, ME) to the university facility (Urbana, IL) on the day the vaginal plug was found (gestation day [GD] 1), arriving at the laboratory on GD 3 after 2 d transport by air and ground. Mice (Exp. 1: n = 250, 16.0 ± 1.2 g BW; Exp. 2: n = 202, 16.2 ± 1.2 g BW; Exp. 3: n = 156, 16.4 ± 1.1 g BW) were housed in individual cages and randomly assigned to dietary treatments (Exp. 1: 0 [CON] and 8% SDP in the diet, ≥ 90 mice/diet; Exp. 2: 0, 1, 2, 4, and 8% SDP in the diet, ≥ 40 mice/diet; Exp. 3: 0, 1, and 8% SDP in the diet, 48 mice/diet) fed from arrival. In Exp. 1 and 2, pregnancy of each mouse was determined on GD 17 based on BW, shape of abdomen, and inspection postmortem, and maternal growth performance from GD 3 to 17 was measured. On GD 19, pregnant mice in Exp. 2 were euthanized to measure number of fetuses and fetal and placental weights. Pregnancy rates in CON were low in both Exp. 1 (11%) and Exp. 2 (7%). The SDP consistently and markedly increased (P < 0.05) pregnancy rates in both Exp. 1 (49%) and Exp. 2 (35-43%) compared with the CON. In Exp. 3, 12 randomly selected mice were euthanized immediately after they arrived as an initial group. From GD 4 to 7, randomly selected mice were also euthanized each day (12 mice/diet). After euthanasia, the abdominal cavity was opened to check pregnancy by uterine inspection and to collect blood and uterus samples for immune measurements. The SDP increased (P < 0.05; 40 vs. 15%) pregnancy rate compared with the CON. Concentrations of indicators of inflammation and stress (uterine TNF-α and IFN-γ, and serum TNF-α, C-reactive protein, and cortisol) were greatest (P < 0.05) and an anti-inflammatory cytokine (TGF-β1

    The objective of the current study was to delineate the optimal cutpoints for depression rating scales during pregnancy and the postpartum period and to assess the perinatal factors influencing these scores. Women participating in prospective investigations of maternal mental illness were enrolled prior to 28 weeks gestation and followed through 6 months postpartum. At each visit, subjects completed self-rated depression scales--Edinburgh Postnatal Depression Scale (EPDS) and Beck Depression Inventory (BDI) and clinician-rated scales--Hamilton Rating Scale for Depression (HRSD(17) and HRSD(21)). These scores were compared to the SCID Mood Module for the presence of fulfilling diagnostic criteria for a major depressive episode (MDE) during 6 perinatal windows: preconception; first trimester; 2nd trimester; 3rd trimester; early postpartum; and later postpartum. Optimal cutpoints were determined by maximizing the sum of each scale's sensitivity and specificity. Stratified ROC analyses determined the impact of previous pregnancy and comparison of initial to follow-up visits. A total of 534 women encompassing 640 pregnancies and 4025 follow-up visits were included. ROC analysis demonstrated that all 4 scales were highly predictive of MDE. The AUCs ranged from 0.857 to 0.971 and were all highly significant (p < .0001). Optimal cutpoints were higher at initial visits and for multigravidas and demonstrated more variability for the self-rated scales. These data indicate that both clinician-rated and self-rated scales can be effective tools in identifying perinatal episodes of major depression. However, the results also suggest that prior childbirth experiences and the use of scales longitudinally across the perinatal period influence optimal cutpoints.

    The purpose of this study is to evaluate whether follicle-stimulating hormone treatment improves sperm DNA parameters and pregnancy outcome in infertile male candidates to in-vitro fertilization.Observational study in 166 infertile male partners of couples undergoing in-vitro fertilization. Eighty-four patients were receiving follicle-stimulating hormone treatment (cases) and 82 refused treatment (controls). Semen parameters, sexual hormones, and sperm nucleus (fluorescence in-situ hybridization, acridine orange, TUNEL, and γH2AX) were evaluated at baseline (T0) and after 3 months (T1), when all subjects underwent assisted reproduction techniques. Statistical analysis was performed by analysis of variance.Compared to baseline, cases showed significant improvements in seminal parameters and DNA fragmentation indexes after follicle-stimulating hormone therapy (all P < 0.05), whereas no changes were observed in controls. Within cases, follicle-stimulating hormone treatment allowed to perform intrauterine insemination in 35 patients with a pregnancy rate of 23.2 %. Intracytoplasmic sperm injection was performed in all controls and in 49 patients from cases, with pregnancy rates of 23.2 and 40.8 %, respectively (P < 0.05). After 3 months (T0 vs. T1) of follicle-stimulating hormone therapy, cases with positive outcome had reduced DNA fragmentation index and lower double strand breaks (P < 0.05 and P < 0.001 vs. negative outcome, respectively).In this observational study, we showed that follicle-stimulating hormone treatment improves sperm DNA fragmentation, which in turn leads to increased pregnancy rates in infertile males undergoing in-vitro fertilization. In particular, double strand breaks (measured with γH2AX test) emerged as the most sensible parameter to follicle-stimulating hormone treatment in predicting reproductive outcome.

    Two experiments were conducted to determine estrous response and pregnancy rate in beef cattle given a controlled internal drug release (CIDR-B) device plus prostaglandin F2 alpha (PGF) at CIDR-B removal, and estradiol or gonadotropin releasing hormone (GnRH). In Experiment I, crossbred beef heifers received a CIDR-B device and 1 mg estradiol benzoate (EB), plus 100 mg progesterone (E + P group; n = 41), 100 micrograms gonadotropin releasing hormone (GnRH group; n = 42), or no further treatment (Control group; n = 42), on Day 0. On Day 7, CIDR-B devices were removed and heifers were treated with PGF. Heifers in the E + P group were given 1 mg EB, 24 h after PGF, and then inseminated 30 h later. Heifers in the GnRH group were given 100 micrograms GnRH, 54 h after PGF, and concurrently inseminated. Control heifers were inseminated 12 h after onset of estrus. The estrous rate was lower (P < 0.01) in the GnRH group (55%) than in either the E + P (100%) or Control (83%) groups. The mean interval from CIDR-B removal to estrus was shorter (P < 0.01) and less variable (P < 0.01) in the E + P group than in the GnRH or Control groups. Pregnancy rate in the E + P group (76%) was higher (P < 0.01) than in the GnRH (48%) or Control (38%) groups. In Experiment II, 84 cows were treated similarly to the E + P group in Experiment I. Cows received 100 mg progesterone and either 1 mg EB or 5 mg estradiol-17 beta (E-17 beta) on Day 0 and either 1 mg of EB or 1 mg of E-17 beta on Day 8 (24 h after CIDR-B removal), in a 2 x 2 factorial design, and were inseminated 30 h later. There were no differences among groups for estrous rates or conception rates. The mean interval from CIDR-B removal to estrus was 44.2 h, s = 11.2. Conception rates were 67%, 62%, 52%, and 71% in Groups E-17 beta/E-17 beta, E-17 beta/EB, EB/E-17 beta, and EB/EB, respectively. In cattle given a CIDR-B device and estradiol plus progesterone, treatment with either EB or E-17 beta effectively synchronized estrus and

    Objectives Intimate partner violence (IPV) is a significant public health problem in South Africa. However, limited research exists on IPV during pregnancy and the postpartum period in South Africa. The purpose of this study is to describe the prevalence, rates and correlates of IPV among South African women during pregnancy and the first nine months postpartum. Methods Data are from a longitudinal study with women recruited during pregnancy between 2008 and 2010 at a public clinic in Durban. We used a modified version of the World Health Organization’s IPV scale to estimate prevalence and rates of IPV during pregnancy, at four months postpartum and nine months postpartum and we used logistic regression to assess the correlates of IPV during this time. Results More than 20% of all women experienced at least one act of physical, psychological or sexual IPV during pregnancy. Nearly one-quarter of all women experienced at least one act of physical, psychological or sexual IPV during the first nine months postpartum. Psychological IPV was the most prevalent type of IPV during pregnancy and the first four months postpartum. Age and previous violence within the relationship were associated with IPV during pregnancy and IPV during the postpartum period. Conclusions The high levels of IPV during pregnancy and the postpartum period highlight the need to develop screening and intervention strategies specifically for this time. Further, women should be screened not only for physical violence but also psychological violence given that psychological violence may result in distinct negative consequences. PMID:24889116

    Control of the white-tailed doe's reproductive cycle is not well documented. The objective was to determine the effects of giving equine chorionic gonadotropin (eCG) at progesterone device removal on fixed time artificial insemination (FTAI) pregnancy rates in white-tailed does. All does (n = 74) were synchronized with a vaginal progesterone implant (CIDR; 0.3 g progesterone), inserted on Day 0 (without regard to stage of estrous cycle), removed 14 days later, and subjected to FTAI, on average, 60 h post-CIDR removal. Of these, 34 were given 200 IU (im) of eCG at CIDR removal. Overall, FTAI pregnancy rate was 50% across 2 yrs (effect of year, P = 0.35). Administration of eCG at CIDR removal did not affect (P = 0.16) pregnancy rate (eCG = 59%; no eCG = 43%). Pregnancy rates were not affected by vulva score or doe disposition. Does that were ≤ 4 yrs old were more likely (P = 0.01) to become pregnant than does > 4 yrs of age. Does inseminated ≥ 60.5 h after CIDR removal were 22 times more likely (P = 0.002) to become pregnant to FTAI than does inseminated < 60.5 h. When frozen-thawed semen was deposited in the cervix or uterus, does were 17 times more likely (P = 0.005) to become pregnant compared with those receiving intravaginal insemination. Fecundity was not different (P = 0.73) across treatment groups (1.6 ± 0.11; no eCG vs. 1.7 ± 0.10; eCG). Furthermore, fecundity of does pregnant to FTAI was not different (P = 0.72) compared with does pregnant to clean-up bucks (1.7 ± 0.08; AI does vs. 1.7 ± 0.09; clean-up bucks). In summary, white-tailed does were successfully inseminated using a 14 days FTAI protocol, eCG may not be essential for acceptable pregnancy rates, and increased pregnancy rates may result when FTAI is done ≥ 60.5 h after progesterone device removal.

    In this study, our purpose was to investigate the possible effect of paternal obesity on intracytoplasmic sperm injection (ICSI) outcomes on the basis of clinical pregnancy outcome. Antropometric measurements of 155 couples, referred to our infertility clinic and who underwent an ICSI cycle, have been evaluated. The study sample were divided into three groups with respect to paternal body mass index (BMI), as normal weight (BMI: 20-24.9), overweight (BMI: 25-29.9) and obese (BMI ≥ 30). Results of conventional semen analysis were also analysed. Clinical pregnancy data, including fertilisation rate, implantation rate, clinical pregnancy rate and live birth rate, were evaluated. Paternal obesity was a significant negative factor for sperm concentration and sperm motility (P = 0.03 and P = 0.01 respectively). A significant decrease of clinical pregnancy rate and live birth rate was associated with increased paternal BMI (P = 0.04 and P = 0.03 respectively). We have not determined a significant difference among groups in terms of fertilisation rate and implantation rate. This study demonstrates that increasing paternal BMI has a negative influence on ICSI success, including clinical pregnancy rate and live birth rate. There is a need for further studies to point the importance of lifestyle changes in order to overcome the negative influence of paternal obesity on couple's fertility.

    Ovine embryos were produced by maturation, fertilization and in vitro culture (IVM/IVF/IVC) of oocytes collected from slaughtered prepubertal ewes. At 24 h post IVM, oocytes were fertilized with fresh semen collected from Lori-Bakhtiari breed at a concentration of 1.0 x l0(6) sperm mL(-1). The presumptive ova/embryos were transferred into the embryo culture medium at 22-24 h post IVF. Following 4 to 7 day in culture, embryos (at morula and blastocyst stage, respectively) were transferred surgically to the uterine horn of synchronized recipients. Pregnancy was diagnosed at day 30 by hormonal assay and at days 55 and 140 of gestation by ultrasonography and pregnancies were allowed to go to term. A total of nine ewes received 27 embryos (3 embryos/ewe). Five ewes received 15 embryos at morula stage and four ewes received 12 embryos at blastocyst stage. From those received morula stage embryos one was pregnant on day 30 (20%), though no pregnancy was diagnosed on each of days 55 and 140. While from those received blastocyst stage embryos, three ewes were pregnant on day 30 (75%) and two ewes (50%) remained pregnant on each of days 55 and 140. In conclusion, day 4 IVM-IVF morula stage embryos had a lower survival rate than did day 7 IVM-IVF blastocysts embryos, following transfer to the synchronized recipient ewes.

    Logistic regression was used to quantify and characterize the effects of changes in marbling score, Warner-Bratzler shear force (WBSF), and consumer panel sensory ratings for tenderness, juiciness, or flavor on the probability of overall consumer acceptance of strip loin steaks from beef carcasses (n = 550). Consumers (n = 489) evaluated steaks for tenderness, juiciness, and flavor using nine-point hedonic scales (1 = like extremely and 9 = dislike extremely) and for overall steak acceptance (satisfied or not satisfied). Predicted acceptance of steaks by consumers was high (> 85%) when the mean consumer sensory rating for tenderness,juiciness, or flavor for a steak was 3 or lower on the hedonic scale. Conversely, predicted consumer acceptance of steaks was low (< or = 10%) when the mean consumer rating for tenderness, juiciness, or flavor for a steak was 5 or higher on the hedonic scale. As mean consumer sensory ratings for tenderness, juiciness, or flavor decreased from 3 to 5, the probability of acceptance of steaks by consumers diminished rapidly in a linear fashion. These results suggest that small changes in consumer sensory ratings for these sensory traits have dramatic effects on the probability of acceptance of steaks by consumers. Marbling score displayed a weak (adjusted R2 = 0.053), yet significant (P < 0.01), relationship to acceptance of steaks by consumers, and the shape of the predicted probability curve for steak acceptance was approximately linear over the entire range of marbling scores (Traces67 to Slightly Abundant97), suggesting that the likelihood of consumer acceptance of steaks increases approximately 10% for each full marbling score increase between Slight to Slightly Abundant. The predicted probability curve for consumer acceptance of steaks was sigmoidal for the WBSF model, with a steep decline in predicted probability of acceptance as WBSF values increased from 3.0 to 5.5 kg. Changes in WBSF within the high (> 5.5 kg) or low (< 3.0 kg

    Successful integration of UAS in the NAS will require that UAS interactions with the air traffic management system be similar to interactions between manned aircraft and air traffic management. For example, UAS response times to air traffic controller (ATCo) clearances should be equivalent to those that are currently found to be acceptable with manned aircraft. Prior studies have examined communication delays with manned aircraft. Unfortunately, there is no analogous body of research for UAS. The goal of the present study was to determine how UAS pilot communication and execution delays affect ATCos' acceptability ratings of UAS pilot responses when the UAS is operating in the NAS. Eight radar-certified controllers managed traffic in a modified ZLA sector with one UAS flying in it. In separate scenarios, the UAS pilot verbal communication and execution delays were either short (1.5 s) or long (5 s) and either constant or variable. The ATCo acceptability of UAS pilot communication and execution delays were measured subjectively via post trial ratings. UAS verbal pilot communication delay, were rated as acceptable 92% of the time when the delay was short. This acceptability level decreased to 64% when the delay was long. UAS pilot execution delay had less of an influence on ATCo acceptability ratings in the present stimulation. Implications of these findings for UAS in the NAS integration are discussed.

    The objective of the present experiment is to study the effect of feed intake restriction on the reproductive performance and pregnancy rate in Egyptian buffalo heifers. Thirty anestrus buffalo heifers were randomly divided into two equal groups. The low feed intake (LFI, n=15, 50 % restriction) group was fed a diet that consists of 3 kg concentrate, 1 kg wheat straw, and 3 kg fresh alfalfa, while the high feed intake (HFI, n=15) group was fed double the amount given to the LFI group for 4 months. All animals were weighed, transrectally examined, and visually checked for the signs of estrus, and blood samples were collected. Heifers in heat were mated with one fertile bull. The number of heifers showing estrus activity was 93.3 % in HFI vs. 20 % in LFI (P<0.01). Ovarian activity started earlier (P=0.03) in the HFI than LFI group. The weight at breeding, the diameter of the dominant follicle, number of heifers showing ovulations, number of services per conception, pregnancy rate, and overall mean of progesterone and estrogen concentrations were significantly higher (P<0.01) in the HFI than in the LFI group. The level of serum total protein, albumin, globulin, glucose, total cholesterol, and calcium were significantly higher (P<0.05) in the HFI group. Restriction of the daily feed intake to 50 % from NRC recommendations impair reproductive performance in terms of increasing the age at first service and reducing the pregnancy rate in buffalo heifers. In conclusion, feed intake could be effective in improvement of reproductive performance in buffalo heifers and further studies should be done on large scale of buffaloes in this point.

    Teenage pregnancy is a common public health problem worldwide. The objective of this ecological study was to investigate the spatial association between teenage pregnancy rates and socioeconomic characteristics of municipalities in São Paulo State, Southeast Brazil. We used a Bayesian model with a spatial distribution following a conditional autoregressive (CAR) form based on Markov Chain Monte Carlo algorithm. We used data from the Live Birth Information System (SINASC) and the Brazilian Institute of Geography and Statistics (IBGE). Early pregnancy was more frequent in municipalities with lower per capital gross domestic product (GDP), higher poverty rate, smaller population, lower human development index (HDI), and a higher percentage of individuals with State social vulnerability index of 5 or 6 (more vulnerable). The study demonstrates a significant association between teenage pregnancy and socioeconomic indicators.

    Background The World Health Organization recommends intermittent preventive treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) alongside long-lasting insecticide-treated nets (LLIN) and case management for reducing the risks associated with malaria in pregnancy in areas of moderate-to-high transmission in sub-Saharan Africa. Due to increasing Plasmodium falciparum resistance to SP, the search for alternative drugs or strategies to control malaria in pregnancy is a priority. We assessed the acceptability among pregnant women and health providers of intermittent screening and treatment (ISTp) and IPTp with dihydroartemisinin-piperaquine (DP) as alternative strategies in the context of an un-blinded clinical trial. Methods Qualitative data were collected through ten focus group discussions with women participating in a randomized controlled trial to evaluate ISTp or IPTp with DP (multi-day regimen) versus IPTp with SP (single dose) in western Kenya. Individual in-depth interviews were conducted with 26 health providers working in the trial facilities and trial staff. Results Women appreciated the advantages of being tested with a rapid diagnostic test (RDT) at every ANC visit (although a few women disliked finger pricks) and accepted that they would not receive any antimalarial when tested RDT-negative. There were differences in women’s experiences of the efficacy of antimalarials between the trial arms, with more women in the IPTp-SP arm reporting they had experienced malaria episodes. Side effects were experienced among women taking DP and SP. Although women and trial staff reported adherence to the full DP regimen within the trial, health providers were not confident that women would adhere to multi-day regimens in non-trial settings. Health providers recognized the advantages of ISTp in reducing unnecessary exposure to drugs, but lacked confidence in the reliability of RDTs compared to microscopy. Conclusions Our findings indicate that, within a

    This study addresses potential management risk factors affecting the incidence of twin pregnancies in high-producing dairy cows. Special attention was paid to the estrus synchronization protocol used before the AI resulting in pregnancy. Possible factors affecting the twin pregnancy rate were analyzed through binary logistic regression procedures on 2015 pregnant cows from July 2010 to July 2011. Twin pregnancy was recorded in 361 of the 2015 pregnancy diagnoses made (17.9%). Twin pregnancy rates differed among herds (P < 0.001) and ranged from 12.4% to 23.9%. Based on the odds ratios, the risk of twin pregnancy was reduced by factors of 0.65 or 0.71 when AI was performed during the warm season or an increasing photoperiod, respectively and increased by a factor of 1.11 for each unit increase in lactation number; by factors of 4.57 or 6.33 in cows that received a progesterone-releasing intravaginal device (PRID) plus 500 or 750 IU of equine chorionic gonadotropin (eCG) 28 days before the pregnancy AI, respectively; by a factor of 2.39 in cows with an ovarian cyst diagnosed in the 14 days prior to AI and treated with prostaglandins (PG); by factors of 1.94 or 3.91 in cows that received two PG doses during the 14 days prior to AI or cows that following failed PRID treatment had received PG started over the 28 days prior to AI, respectively; and by a factor of 2.58 in cows that had previously delivered twins compared to cows delivering singletons. Our results indicate that cow factors, such as lactation number and previous twining, as well as environmental factors, such as photoperiod and season and management related to synchronization protocols affect significantly the incidence of twin pregnancies.

    Objective To investigate effect of the afterloaded external guidance embryo transfer technique on pregnancy rates in single embryo transfer intracytoplasmic sperm injection (ICSI) cycles. Material and Methods This retrospective study was performed at the Dr. Zekai Tahir Burak Women’s Health Research and Education Hospital. Three hundred and thirteen women who underwent ICSI were included in the study. Subjects were categorized according to the embryo transfer technique; Group 1 (n: 232): easy transfer with a soft catheter, Group 2 (n: 45): after external guidance transfer, and Group 3 (n: 36): difficult transfer with a stylet. Basal parameters, clinical and laboratory IVF outcomes and pregnancy rates were studied. Results Infertility etiology, basal follicle stimulating hormone (FSH) levels, antral follicle count, duration of stimulation, total dose of gonadotropin, peak estradiol levels, endometrial thickness, oocyte number, 2 PN, and fertilization rate were similar between the three groups (p>0.05). Despite the decreased pregnancy rate in Group 3, there were no differences in clinical pregnancy rates among the groups (p=0.204). Conclusion Embryo transfer is one of the critical steps in assisted reproduction procedures. Using the afterloaded external guidance embryo transfer technique did not improve pregnancy rates.

    In six field trials, doses between 1.0 and 6.0 x 10(6) total sexed, frozen-thawed sperm were inseminated into the uterine body or bilaterally into the uterine horns of heifers and nursing Angus cows 12 or 24h after observed estrus. Except for one comparison in one trial in which uterine body insemination was slightly superior (P<0.05) to uterine horn insemination, there was no significant (P>0.1) difference between sites of semen deposition. Additionally, except for one small study with limited numbers, there was essentially no difference in pregnancy rates in the range between 1.5 and 6 x 10(6) sexed, frozen-thawed sperm per inseminate. Pregnancy rates with smaller doses of sexed sperm averaged about 75% of controls of 20 x 10(6) total frozen-thawed, unsexed sperm. While 1.0 x 10(6) sexed, frozen-thawed sperm per insemination dose resulted in decreased pregnancy rates compared to larger doses, the lesser fertility with sexed sperm could not be compensated by increasing sperm numbers in the range of 1.5-6 x 10(6) sperm per dose. Pregnancy rates with 2 x 10(6) sexed, frozen-thawed sperm per dose were not markedly less than control pregnancy rates with 20 x 10(6) frozen-thawed unsexed sperm/dose in well-managed herds.

    Background: Implantation failure is one of the most important factors limiting success in IVF treatment. The majority of trials have demonstrated favorable effect of endometrial injury on implantation success rate especially in women with recurrent implantation failure, while some studies failed to detect any benefit. Objective: The purpose of our trial was to explore whether endometrial injury in luteal phase prior to frozen-thawed embryo transfer cycles would improve pregnancy outcomes? Materials and Methods: We conducted a prospective controlled trial of 93 consecutive subjects at a research and clinical center for infertility. All women were undergone frozen-thawed embryo transfer (FTE) cycles. Women in the experimental group underwent endometrial biopsy with a Pipelle catheter in luteal phase proceeding FET cycle. Primary outcomes were implantation and clinical pregnancy rates and secondary outcomes were chemical, ongoing and multiple pregnancy and miscarriage rates. Results: 45 subjects who underwent endometrial injury (EI) were compared with 48 control group which did not include any uterine manipulation. There were no significant differences in baseline and cycle characteristics between two groups. The difference in implantation rate was trend to statistically significance, 11.8% in EI group vs. 20.5% in control group (p=0.091). The chemical, clinical and ongoing pregnancy rates were lower in EI group compared with control group but not statistically significant. The multiple pregnancy rate and miscarriage rate also were lower in EI group compared with control group. Conclusion: Based on results of this study, local injury to endometrium in luteal phase prior to FET cycle had a negative impact on implantation and clinical pregnancy rates. PMID:27525329

    Seven consecutive patients with Eisenmenber's syndrome, cared for by the obstetric team in conjunction with the cardiology service, were reviewed to assess the possible role of prophylactic heparin therapy and intensive care on the outcome of these patients. In each patient, the diagnosis of Eisenmenger's syndrome was established by the demonstration of equal pulmonary arterial and aortic pressures with a predominantly right-to-left shunt at cardiac catheterization. Five of the seven patients died as follows: Three patients died between the fifth and eighth post-partum days, one patient died during the twenty-sixth week of pregnancy, and one patient died on the fifth postoperative day following tubal ligation. All of these five patients received prophylactic heparin therapy. In three patients, heparin therapy was complicated by excessive bleeding during the postoperative or postpartum period. Autopsy examination in two patients revealed no evidence of thrombosis in the main pulmonary arteries and no pulmonary infarction, contrary to the antemortem clinical suspicion. The two survivors did not receive prophylactic heparin. They comprised one patient who had normal delivery and one patient who underwent tubal ligation and induction of abortion. We conclude that the prohibitive mortality rate of Eisenmenger's syndrome during pregnancy, puerpurium, or surgical procedures probably cannot be modified with prophylactic heparin therapy. Anticoagulant treatment does not prevent deterioration of patients and probably compounds the problem by causing significant bleeding.

  17. Abstinence-only education and teen pregnancy rates: why we need comprehensive sex education in the U.S.

    The United States ranks first among developed nations in rates of both teenage pregnancy and sexually transmitted diseases. In an effort to reduce these rates, the U.S. government has funded abstinence-only sex education programs for more than a decade. However, a public controversy remains over whether this investment has been successful and whether these programs should be continued. Using the most recent national data (2005) from all U.S. states with information on sex education laws or policies (N = 48), we show that increasing emphasis on abstinence education is positively correlated with teenage pregnancy and birth rates. This trend remains significant after accounting for socioeconomic status, teen educational attainment, ethnic composition of the teen population, and availability of Medicaid waivers for family planning services in each state. These data show clearly that abstinence-only education as a state policy is ineffective in preventing teenage pregnancy and may actually be contributing to the high teenage pregnancy rates in the U.S. In alignment with the new evidence-based Teen Pregnancy Prevention Initiative and the Precaution Adoption Process Model advocated by the National Institutes of Health, we propose the integration of comprehensive sex and STD education into the biology curriculum in middle and high school science classes and a parallel social studies curriculum that addresses risk-aversion behaviors and planning for the future.

    The present survey explored the acceptability of virtual reality (VR) exposure and in vivo exposure in 150 participants suffering from specific phobias. Seventy-six percent chose VR over in vivo exposure, and the refusal rate for in vivo exposure (27%) was higher than the refusal rate for VR exposure (3%). Results suggest that VR exposure could help increase the number of people who seek exposure therapy for phobias.

    Across taxa, cooperative breeding has been associated with high reproductive skew. Cooperatively breeding golden lion tamarins (Leontopithecus rosalia) were long thought to have a monogynous mating system in which reproduction was limited to a single dominant female. Subordinates with few reproductive opportunities delayed dispersal and remained in the natal group to provide alloparental care to siblings, thus allowing dominant reproductive females to meet the energetic needs associated with high rates of reproduction and successful infant rearing. The goal of this study was to re-assess monogyny in wild golden lion tamarin groups based upon pregnancy diagnoses that used non-invasive enzyme immunoassay for progesterone and cortisol, combined with weekly data on individual weight gain, bi-annual physical examinations noting pregnancy and lactation status and daily behavioral observations. We established quantitative and qualitative criteria to detect and determine the timing of pregnancies that did not result in the birth of infants. Pregnancy polygyny occurred in 83% of golden lion tamarin groups studied. The loss of 64% of subordinate pregnancies compared to only 15% by dominant females limited reproductive success mainly to dominant females, thus maintaining high reproductive skew in female golden lion tamarins. Pregnancy loss by subordinate adults did not appear to result from dominant interference in subordinate hormonal mechanisms, but more likely resulted from subordinate abandonment of newborn infants to mitigate dominant aggression.

    In vitro-produced (IVP) bovine embryos are more sensitive to cryopreservation than their in vivo counterparts due to their higher lipid concentrations, whereas Bos indicus IVP embryos are even more sensitive than Bos taurus IVP embryos. To examine the effects of a lipolytic agent, before vitrification of Bos indicus IVP embryos, on embryo survival, viability, and pregnancy rates, two experiments were conducted. In experiment 1, Bos indicus (Nelore) embryos were produced from abattoir-derived ovaries and allocated into two groups. In the treatment group, 10 μM of forskolin was added to the in vitro culture medium on Day 5 and incubated for 48 hours. On Day 7 of culture, IVP-expanded blastocysts from both the control (n = 101) and treatment (n = 112) groups were vitrified with ethylene glycol and DMSO via the Cryotop procedure. Although there was no significant difference between the rates of blastocoel reexpansion and hatching of the embryos exposed to forskolin (87.5% and 70.5%, respectively) compared with the control embryos (79.2% and 63.3%, respectively), the numerically superior rates of the embryos exposed to forskolin led to another experiment. In experiment 2, blastocysts produced from the ovum pick up were exposed or not exposed to the lipolytic agent and vitrified as in experiment 1. Embryos treated with forskolin had higher pregnancy rates than the control group (48.8% vs. 18.5%). In view of these results, 1908 Bos indicus embryos were produced from ovum pick up, exposed to the lipolytic agent, and blastocysts were transferred to recipients, and the pregnancy rates of the embryos of various breeds were compared. The mean pregnancy rate obtained was 43.2%. All data were analyzed by chi-square or by binary logistic regression (P ≤ 0.05). In conclusion, treatment with forskolin before vitrification improved cryotolerance of Bos indicus IVP embryos, resulting in good post-transfer pregnancy rates.

    Background There are different factors that influence treatment outcome after ovarian stimulation and timed-intercourse or intrauterine insemination (IUI). After patient age, it has been suggested that timing of insemination in relation to ovulation is probably the most important variable affecting the success of treatment. The objective of this study is to study the value of human chorionic gonadotropin (hCG) administration and occurrence of luteinizing hormone (LH) surge in timing insemination on the treatment outcome after follicular monitoring with timed-intercourse or intrauterine insemination, with or without ovarian stimulation. Methods Retrospective analysis of 2000 consecutive completed treatment cycles (637 timed-intercourse and 1363 intrauterine insemination cycles). Stimulation protocols included clomiphene alone or with FSH injection, letrozole (an aromatase inhibitor) alone or with FSH, and FSH alone. LH-surge was defined as an increase in LH level ≥200% over mean of preceding two days. When given, hCG was administered at a dose of 10,000 IU. The main outcome was clinical pregnancy rate per cycle. Results Higher pregnancy rates occurred in cycles in which hCG was given. Occurrence of an LH-surge was associated with a higher pregnancy rate with clomiphene treatment, but a lower pregnancy rate with FSH treatment. Conclusions hCG administration is associated with a favorable outcome during ovarian stimulation. Awaiting occurrence of LH-surge is associated with a better outcome with CC but not with FSH treatment. PMID:15239837

  3. Pregnancy-related low back pain and pelvic girdle pain approximately 14 months after pregnancy – pain status, self-rated health and family situation

    PubMed Central

    2014-01-01

    Background Pelvic girdle pain (PGP) in pregnancy is distinct from pregnancy-related low back pain (PLBP). However, women with combined PLBP and PGP report more serious consequences in terms of health and function. PGP has been estimated to affect about half of pregnant women, where 25% experience serious pain and 8% experience severe disability. To date there are relatively few studies regarding persistent PLBP/PGP postpartum of more than 3 months, thus the main objective was to identify the prevalence of persistent PLBP and PGP as well as the differences over time in regard to pain status, self-rated health (SRH) and family situation at 12 months postpartum. Methods The study is a 12 month follow-up of a cohort of pregnant women developing PLBP and PGP during pregnancy, and who experienced persistent pain at 6 month follow-up after pregnancy. Women reporting PLBP/PGP (n = 639) during pregnancy were followed up with a second questionnaire at approximately six month after delivery. Women reporting recurrent or persistent LBP/PGP at the second questionnaire (n = 200) were sent a third questionnaire at 12 month postpartum. Results A total of 176 women responded to the questionnaire. Thirty-four women (19.3%) reported remission of LBP/PGP, whereas 65.3% (n = 115) and 15.3% (n = 27), reported recurrent LBP/PGP or continuous LBP/PGP, respectively. The time between base line and the 12 months follow-up was in actuality 14 months. Women with previous LBP before pregnancy had an increased odds ratio (OR) of reporting ‘recurrent pain’ (OR = 2.47) or ‘continuous pain’ (OR = 3.35) postpartum compared to women who reported ‘no pain’ at the follow-up. Women with ‘continuous pain’ reported statistically significant higher level of pain at all measure points (0, 6 and 12 months postpartum). Non-responders were found to report a statistically significant less positive scoring regarding relationship satisfaction compared to responders

    Summary Background There is a growing interest in examining death rates associated with different pregnancy outcomes for time periods beyond one year. Previous population studies, however, have failed to control for complete reproductive histories. In this study we seek to eliminate the potential confounding effect of unknown prior pregnancy history by examining mortality rates associated specifically with first pregnancy outcome alone. We also examine differences in mortality rates associated with early abortion and late abortions (after 12 weeks). Material/Method Medical records for the entire population of women born in Denmark between 1962 and 1991 and were alive in 1980, were linked to death certificates. Mortality rates associated with first pregnancy outcomes (delivery, miscarriage, abortion, and late abortion) were calculated. Odds ratios examining death rates based on reproductive outcomes, adjusted for age at first pregnancy and year of women’s births, were also calculated. Results A total of 463,473 women had their first pregnancy between 1980 and 2004, of whom 2,238 died. In nearly all time periods examined, mortality rates associated with miscarriage or abortion of a first pregnancy were higher than those associated with birth. Compared to women who delivered, the age and birth year adjusted cumulative risk of death for women who had a first trimester abortion was significantly higher in all periods examined, from 180 days (OR=1.84; 1.11 <95% CI <3.71) through 10 years (1.39; 1.22 <95% CI <1.61), as was the risk for women who had abortions after 12 weeks from one year (OR=4.31; 2.18 <95% CI <8.54) through 10 years (OR=2.41; 1.56 <95% CI <2.41). For women who miscarried, the risk was significantly higher for cumulative deaths through 4 years (OR=1.75; 1.34 <95% CI <2.27) and at 10 years (OR=1.48; 1.18 <95% CI <1.85). Conclusions Compared to women who delivered, women who had an early or late abortion had significantly higher mortality rates within 1

    Objective To compare the risk of ectopic pregnancy (EP) after embryo transfer on day 3(D3-ET) and day 5(D5-ET). Design Meta-analysis Patients Women with pregnancy resulting from in vitro undergoing in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) Result(s) Twenty-two studies were identified through research conducted using the PubMed, Embase, and Cochrane databases and ClinicalTrials.gov. All studies were conducted prior to October 2016. Adding the reproductive data from our center, a total of 143 643 pregnancies were reviewed(D3-ET: n = 62027,D5-ET:n = 81616). A lower EP rate was found in women undergoing D5-ET than in those undergoing D3-ET [relative risk (RR), 0.67;95% confidence interval (CI), 0.54–0.85;143643 pregnancies in 23 studies; I2 = 67%]. These results were validated in subgroups of fresh embryo-transfer (Fre-ET) cycles [RR, 0.78; 95%CI, 0.69–0.88; 91 871 pregnancies in 21 studies; I2 = 29%] and frozen-thawed embryo-transfer (Fro-ET) cycles [RR, 0.43; 95%CI, 0.36–0.51; 51 772 pregnancies in 10 studies; I2 = 33%]. After separating out the randomized controlled trials (RCTs), a significant difference was found in the retrospective studies in both subgroups [both Fre-ET (RR,0.78;95% CI 0.69–0.88);91182 pregnancies in 14 studies; I2 = 45%] and Fro-ET(RR,0.43;95% CI 0.36–0.51; 51751pregnancies in 9 studies;I2 = 33%)], while the RCTs showed no statistical significance for Fre-ET cycles[RR,0.86;95% CI 0.32–2.26); 689 pregnancies in 7 studies; I2 = 0%]. Conclusion(s) The present study indicates that D5-ET reduces the risk for EP in cycles that use IVF or ICSI, compared with D3-ET. It suggests that D5-ET may be a better choice for decreasing the EP rate in assisted reproductive technology. Further high-quality randomized controlled trials are anticipated. PMID:28121989

    We compared the effects of porcine luteinizing hormone (pLH) versus gonadotropin-releasing hormone (GnRH) on ovulatory response and pregnancy rate after timed artificial insemination (TAI) in 605 lactating dairy cows. Cows (mean+/-SEM: 2.4+/-0.08 lactations, 109.0+/-2.5 d in milk, and 2.8+/-0.02 body condition score) at three locations were assigned to receive, in a 2x2 factorial design, either 100 microg GnRH or 25mg pLH im on Day 0, 500 microg cloprostenol (PGF) on Day 7, and GnRH or pLH on Day 9, with TAI 14 to 18h later. Ultrasonographic examinations were performed in a subset of cows on Days 0, 7, 10, and 11 to determine ovulations, presence of corpus luteum, and follicle diameter and in all cows 32 d after TAI for pregnancy determination. In 35 cows, plasma progesterone concentrations were determined 0, 3, 4, 5, 6, 7, and 12 d after ovulation. The proportion of noncyclic cows and cows with ovarian cysts on Day 0 were 12% and 6%, respectively. Ovulatory response to first treatment was 62% versus 44% for pLH and GnRH and 78% versus 50% for noncyclic and cyclic cows (P<0.01). Location, ovulatory response to first pLH or GnRH, cyclic status, presence of an ovarian cyst, and preovulatory follicle size did not affect pregnancy rate. Plasma progesterone concentrations after TAI did not differ among treatments. Pregnancy rate to TAI was greater (P<0.01) in the GnRH/PGF/pLH group (42%) than in the other three groups (28%, 30%, and 26% for GnRH/PGF/GnRH, pLH/PGF/GnRH, and pLH/PGF/pLH, respectively). Although only 3% of cows given pLH in lieu of GnRH on Day 9 lost their embryo versus 7% in those subjected to a conventional TAI using two GnRH treatments, the difference was not statistically significant. In summary, pLH treatment on Day 0 increased ovulatory response but not pregnancy rate. Cows treated with GnRH/PGF/pLH had the highest pregnancy rate to TAI, but progesterone concentrations after TAI were not increased. In addition, preovulatory follicle diameter did not

    Objective The aim of the present retrospective study was to evaluate intrauterine insemination (IUI) clinical experiences and to define the variables for predicting success. Material and Methods The present study was an observational trial performed in a private IVF center on subfertile couples who had applied for treatment between 2002 and 2012, in which the data of 503 IUI cases were retrospectively reviewed. Couples who had been diagnosed with unexplained and mild male subfertility were included. The primary outcome measure was the clinical pregnancy rate in an attempt to form a predictive model for the odds of a clinical pregnancy. Recorded parameters were used to determine the prediction model. Results Utilizing univariate logistic regression analysis, clinical pregnancy was positively associated with the duration of infertility (OR=1.09, p=0.089), secondary infertility (OR=1.77, p=0.050), and +4 sperm motility after preparation (OR=1.03, p=0.091). Following an adjustment analysis involving a multivariate logistic regression, clinical pregnancy was still found to positively associate with secondary infertility (OR=2.51, p=0.008). Conclusion IUI success in secondary infertile couples who were in the unexplained infertility and mild male subfertility groups was higher than that in primary infertile couples, and the chances of pregnancy increased as sperm numbers with +4 motility increased. It is difficult to concomitantly evaluate all these parameters and to determine a predictive parameter in IUI independent from other factors. PMID:27651720

    Background: The objective of this study was to identify the prognostic factors that influence the outcome of ovarian stimulation with intrauterine insemination (IUI) cycles in couples with different infertility etiology. Materials and Methods: This retrospective study was performed in data of 1348 IUI cycles with ovarian stimulation by clomiphene citrate (CC) and/or gonadotropins in 632 women with five different infertility etiology subgroups at Akbarabbadi Hospital, Tehran, Iran. Results: The pregnancy rate (PR)/ cycle was highest (19.9%) among couples with unexplained infertility and lowest (10.6%) in couples with multiple factors infertility. In cases of unexplained infertility, the best PRs were seen after CC plus gonadotropins stimulation (26.3%) and with inseminated motile sperm count>30×106 (21.9%), but the tendency didn’t reach statistical significant. In the ovarian factor group, the best PRs were observed in women aged between 30 and 34 years (20.8%), with 2-3 preovulatory follicles (37.8%) and infertility duration between 1and 3 years (20.8%), while only infertility duration (p=0.03) and number of preovulatory follicles (p=0.01) were statistically significant. Multiple logistic regression analysis determined that number of preovulatory follicles (p=0.02), duration of infertility (p=0.015), age (p=0.019), infertility etiology (p=0.05) and stimulation regimen (p=0.01) were significant independent factors in order to predict overall clinical PR. Conclusion: The etiology of infertility is important to achieve remarkable IUI success. It is worth mentioning that within different etiologies of infertility, the demographic and cycles characteristics of couples did not show the same effect. Favorable variables for treatment success are as follows: age <40, duration of infertility ≤5 years and a cause of infertility except of multiple factors. PMID:24520471

    Monitoring procedures are the basis to evaluate the clinical state of patients and to assess changes in their conditions, thus providing necessary interventions in time. Both these two objectives can be achieved by integrating technological development with methodological tools, thus allowing accurate classification and extraction of useful diagnostic information. The paper is focused on monitoring procedures applied to fetal heart rate variability (FHRV) signals, collected during pregnancy, in order to assess fetal well-being. The use of linear time and frequency techniques as well as the computation of non linear indices can contribute to enhancing the diagnostic power and reliability of fetal monitoring. The paper shows how advanced signal processing approaches can contribute to developing new diagnostic and classification indices. Their usefulness is evaluated by comparing two selected populations: normal fetuses and intra uterine growth restricted (IUGR) fetuses. Results show that the computation of different indices on FHRV signals, either linear and nonlinear, gives helpful indications to describe pathophysiological mechanisms involved in the cardiovascular and neural system controlling the fetal heart. As a further contribution, the paper briefly describes how the introduction of wearable systems for fetal ECG recording could provide new technological solutions improving the quality and usability of prenatal monitoring.

    The growth of the Gyr breed in Brazil in terms of genetic gain for milk, along with conditions for market, has led to the use of ovum pick-up in vitro production (OPU-IVP) as a leader in biotechnology for the multiplication of genetic material. The aim of this study was to investigate phenotypic correlations between OPU-IVP-linked characteristics and pregnancy rates registered in an embryo transfer program using Gyr cows as oocyte donors. Data collected from 211 OPU sessions and 298 embryo transfers during the years 2012 and 2013 were analyzed and statistical analysis was performed. Estimates of simple Pearson correlations were calculated for NVcoc and PVcoc (number and proportion of viable cumulus-oocyte complexes, respectively); NcleavD4 and PcleavD4 (number and proportion of cleaved embryos on day 4 of culture, respectively); NTembD7 and PTembD7 (number and proportion of transferable embryos on day 7 of culture, respectively); NPrD30 and PPrD30 (number and proportion of pregnancies 30 days after transfer, respectively); and NPrD60 and PPrD60 (number and proportion of pregnancies 60 days after transfer, respectively). Moderate to moderately high correlations were found for all numerical characteristics, suggesting these as the most suitable parameters for selection of oocyte donors in Gyr programs. NVcoc is proposed as a selection trait due to positive correlations with percentage traits and pregnancy rates 30 and 60 days after transfer.

    Background Untreated hypothyroidism can lead to ovulatory dysfunction resulting in oligo-amenorrhea. Treatment with levothyroxine can reverse such dysfunction and thus should improve fertility. The purpose of this retrospective study was to assess whether in vitro fertilization (IVF) pregnancy rates differ in levothyroxine-treated women with hypothyroidism compared to women without thyroid dysfunction/disorders. Methods Treated hypothyroid and euthyroid women undergoing IVF at an academic IVF center were studied after Institutional Review Board approval. Women with hypothyroidism were treated with levothyroxine 0.025–0.15 mg/day for at least 3 months to maintain baseline thyrotropin (TSH) levels of 0.35–4.0 μU/mL prior to commencing IVF treatment (HYPO-Rx group). Causes of infertility were similar in both groups with the exception of male factor, which was more common in the HYPO-Rx group. The main outcomes studied were implantation rate, clinical pregnancy rate, clinical miscarriage rate, and live birth rate. Results We reviewed the first IVF retrieval cycle performed on 240 women aged 37 years or less during the period January 2003 to December 2007. Women with treated hypothyroidism (n=21) had significantly less implantation, clinical pregnancy, and live birth rates than euthyroid women (n=219). Conclusions We conclude that, despite levothyroxine treatment, women with hypothyroidism have a significantly decreased chance of achieving a pregnancy following IVF compared to euthyroid patients. A larger prospective study is necessary to assess confounding variables, confirm these findings, and determine the optimal level of TSH prior to and during controlled ovarian hyperstimulation for IVF.

    Social preferences like interpersonal altruism, fairness, reciprocity and inequity aversion are inherently linked to departures from pure self-interest. During economic interactions, for example, defectors may be punished even if this implies a cost for the punishers. This violation of canonical assumptions in economics indicates that socially oriented decisions may predominate over self-centred stances. Here we explore whether the personal experience of pain changes the balance between self-gain and socially based choices. We used laser stimulation to induce pain or a warm sensation in subjects playing a modified version of the Ultimatum Game (UG) both in the role of responder and proposer. After each shot, responders evaluated the fairness of the offer. Moreover, responders and proposers rated the intensity and unpleasantness of the sensation evoked by the laser stimulation. Results show that suffering proposers decrease fair offers and suffering responders increase their acceptance rate irrespective of economic offer. Crucially, the intensity of painful stimulation has a predictive role on Moderately Unfair offers' acceptance rates. Thus the personal experience of pain may favour the emergence of a self-centered perspective aimed at maximizing self-gain. The results suggest that bodily states play a fundamental role in higher-order interpersonal negotiations and interactions.

    Poor ovarian response (POR) often means low success rates after in vitro fertilisation (IVF). We aim to study the impact of a low-dose growth hormone (GH) supplementation in pregnancy rates in poor responders in a prospective, self-controlled study of 64 poor responders to previous IVF cycles, who failed to achieve pregnancy and were supplemented with low-doses of GH in a subsequent cycle using the same gonadotropin dose and protocol. Our primary endpoint was the clinical pregnancy rate (CPR), considering secondary endpoints, the number of retrieved oocytes, embryos, embryo quality and the proportion of cycles with embryo transfer. CPR in the GH group was 34.4%. Significant differences were observed for the GH group both in the number of top quality embryos (0.64 ± 0.88 versus 1.03 ± 1.17, p < 0.05) and cryopreserved embryos (0.3 ± 0.81 versus 0.85 ± 1.49, p < 0.05). This is, to our knowledge, the first clinical trial to use a low dose of GH as a supplement for IVF in POR patients. Despite this low dose, we achieved excellent success rates in patients with a very poor prognosis, at a reasonable cost and without side effects, which makes this a safe and cost-effective alternative.

    In a prospective study of 807 consecutive women shown to have an apparently normal uterus after hysterosalpingography, hysteroscopy or pelvic ultrasonography prior to IVF or intracytoplasmic sperm injection (ICSI) and embryo transfer, the position and length of the uterine cavity was measured routinely at a pre-treatment mock transfer procedure. The apparent length of the uterine cavity was <7 cm in 128 women (group 1), 7-9 cm in 594 women (group 2) and >9 cm in 85 women (group 3). The uterus was noted to be retroverted in 38. 2% (308) women. The embryo transfer catheter was advanced to 5 mm from the uterine fundus based on the previously determined cavity length in all the embryo transfer procedures at 48 h after oocyte collection. Implantation and clinical pregnancy rates were not significantly different with respect to position of the uterus, difficulties encountered in passage of the catheter, mean age of the women, aetiology or duration of infertility or embryology events. An apparently greater cavity length was seen in older and/or parous women, but the difference was not statistically significant. Although the highest implantation and clinical pregnancy rates were seen in women with a cavity length of 7-9 cm (group 2) the differences were not statistically significant: group 1, 18.9 and 36. 7%; group 2, 21.0 and 46.5%; and group 3, 17.3 and 32.9% respectively. The incidence of ectopic pregnancy per reported clinical pregnancy was highest in group 1 women, being 14.9% (7/47) in comparison with group 2 (1.8%, 5/276) and group 3 (0%, 0/27) (P: < 0.0005), suggesting that the size of the uterus is a critical factor in the aetiology of ectopic pregnancy in IVF/ICSI-embryo transfer.

    In this review, effects of the composition of the inseminate on uterine response and pregnancy rates in mares are discussed. The inseminate can differ for volume, sperm concentration, total sperm numbers, presence, absence, or proportion of seminal plasma, and extender composition. Semen can be used as fresh, cooled, or frozen. The site of semen deposition also plays a role; semen is deposited either into the uterine body (standard artificial insemination (AI)) or into the tip of the uterine horn ipsilateral to the preovulatory follicle (deep AI) using the hysterocopical or transrectally guided techniques. In addition to pregnancy rates, some uterine responses to the inseminate are considered including myometrial contractions, transport and elimination of sperm, and uterine inflammation, which is reflected as numbers of polymorphonuclear leukocytes, enzyme levels, and presence of intrauterine fluid. Reproductively normal and abnormal mares are compared.

    Maternal preconception diet is proposed to affect fertility. Prior research assessing the effect of altering the fatty acid profile on female fertility is conflicting. The aim of this study was to assess the effect of preconception maternal diet, specifically fatty acid profile, on pregnancies and live births following in vitro fertilisation (IVF). Forty-six overweight and obese women undergoing IVF were randomised to a diet and physical activity intervention (intervention) or standard care (control). Outcome measures included pregnancy, live birth and pre-study dietary intake from food frequency questionnaire. Twenty pregnancies (n = 12/18 vs. n = 8/20, p = 0.12) and 12 live births (n = 7/18 vs. n = 5/20, p = 0.48) occurred following the intervention with no differences between the treatment groups. On analysis adjusted for BMI and smoking status, women who became pregnant had higher levels of polyunsaturated fatty acid (PUFA) intake (p = 0.03), specifically omega-6 PUFA and linoleic acid (LA) (p = 0.045) with a trend for an elevated intake of omega-3 PUFA (p = 0.06). There were no dietary differences for women who did or did not have a live birth. Maternal preconception PUFA, and specifically omega-6 and LA intake, are associated with improved pregnancy rates in overweight and obese women undergoing IVF. This has implications for optimising fertility through preconception nutrition.

    Background Maternal immunization has gained traction as a strategy to diminish maternal and young infant mortality attributable to infectious diseases. Background rates of adverse pregnancy outcomes are crucial to interpret results of clinical trials in Sub-Saharan Africa. Methods We developed a mathematical model that calculates a clinical trial's expected number of neonatal and maternal deaths at an interim safety assessment based on the person-time observed during different risk windows. This model was compared to crude multiplication of the maternal mortality ratio and neonatal mortality rate by the number of live births. Systematic reviews of severe acute maternal morbidity (SAMM), low birth weight (LBW), prematurity, and major congenital malformations (MCM) in Sub-Saharan African countries were also performed. Findings Accounting for the person-time observed during different risk periods yields lower, more conservative estimates of expected maternal and neonatal deaths, particularly at an interim safety evaluation soon after a large number of deliveries. Median incidence of SAMM in 16 reports was 40.7 (IQR: 10.6–73.3) per 1,000 total births, and the most common causes were hemorrhage (34%), dystocia (22%), and severe hypertensive disorders of pregnancy (22%). Proportions of liveborn infants who were LBW (median 13.3%, IQR: 9.9–16.4) or premature (median 15.4%, IQR: 10.6–19.1) were similar across geographic region, study design, and institutional setting. The median incidence of MCM per 1,000 live births was 14.4 (IQR: 5.5–17.6), with the musculoskeletal system comprising 30%. Interpretation Some clinical trials assessing whether maternal immunization can improve pregnancy and young infant outcomes in the developing world have made ethics-based decisions not to use a pure placebo control. Consequently, reliable background rates of adverse pregnancy outcomes are necessary to distinguish between vaccine benefits and safety concerns. Local studies that

    The rating of acceptable load (RAL) attained with a standard test (RALSt) and a wrk-simulating test (RALW) for postal parcel sorting was related to anthropometric, muscle strength, and spinal mobility characteristics of 18 male sorters. The subjects comprised a subsample of 103 experienced male sorters who carried out the RAL tests at postal sorting centres. The dynamic hand-grip endurance correlated significantly (p = 0.036) to the RALSt results. Correspondingly, there was a significant correlation (p = 0.044) between the ratio of maximal isometric strength of trunk extension to body weight and the RALW. The dynamic hand-grip endurance predicted 26% of the variation in the RALSt; in the RALW the maximal isometric strength of trunk flexion to body weight ratio predicted 24%. The subjects who rated heavier weights for RALSt tended to have a better trunk mobility. The dynamic endurance of hand-grip muscles, trunk strength, and spinal flexibility seemed to be the most powerful predictors for the psychophysically assessed 'acceptable loads' in experienced workers performing manual materials handling tasks.

    Affective illness is common in women, and the puerperium is a time of particular vulnerability. Gender differences in the expression of affective disorders have been attributed to the impact of hormonal influence, socialization, and genetics. Dramatic fluctuations in gonadal hormones that occur following childbirth, influences the increased incidence of mood disorders during this time. Numerous tools including the Edinburgh Postpartum Depression Scale can be used to screen for depression during pregnancy and postpartum. While screening tools may assist with appropriately identifying women who should be further assessed, their use alone does not significantly increase treatment seeking in women, even when their providers are notified about risk. Many studies demonstrate that only a small number (18%) of women who meet criteria for major depressive disorder seek treatment during pregnancy and postpartum. Additionally, common symptoms of depression (sleep, energy and appetite change) may be misinterpreted as normative experiences of pregnancy.Treatment engagement is important as untreated depression during pregnancy may have unfavorable outcomes for both women and children. Complications of pregnancy associated with depression include: inadequate weight gain,under utilization of prenatal care, increased substance use, and premature birth. Human studies demonstrate that perceived life-event stress, as well as depression and anxiety predicted lower birth weight, decreased Apgar scores, and smaller head circumference, and small for gestational age babies. Postpartum depression (PPD) is a common clinical disorder occurring in 15% of deliveries,making it one of the most frequent conditions to complicate pregnancy. Risk factors include past personal or family history of depression, sing marital status, poor health functioning, lower SES, and alcohol use. Women who have a prior history of postpartum depression, particularly with features of bipolarity or psychosis may be at

    1980-09-01

    The influence of male-induced early puberty on female reproductive rate was determined in three lines of mice differing in litter size and body weight. The lines originated from a single base population and had undergone 20 generations of selection for the following criteria: large litter size at birth (L(+)), large litter size and small 6-week body weight (L(+)W(-)), or small litter size and large 6-week body weight (L(-)W(+)). Females were paired with a mature intact male of the same line at 3, 5 or 7 weeks of age. Mean mating age, averaged over lines, was 26.5 ± .3, 38.3 ± .3 and 52.7 ± .3 days. Exposure to a mature male accelerated female sexual maturation in each line. When contrasted with their sibs mated at a later age, early-pregnant females from each line exhibited a decline in one or more component of reproductive performance, suggesting that the physiological state of the very young female was not optimum for normal pregnancy. In comparisons of early and later mating ages, all three lines showed a decreased littering rate at first mating, number born alive, and individual birth weight of progeny adjusted for litter size; L(+) and L(+)W(-) mice showed an increased perinatal mortality rate; L(+) and L(-)W(+) had a reduction in litter size at birth. When the L(+), L(+)W(-) and L(-)W(+) lines were compared with an unselected strain and a line selected for high postweaning gain in similar experiments, a genotype by environment interaction was apparent since all lines did not respond in a similar manner to early mating. The line ranking for litter size at birth for each age at male-exposure was L(+)>L(+)W(-)>L(-)W(+), despite the significant line by age interaction. When litter size was adjusted by covariance for body weight at mating, the significant effects of age at male-exposure and line by age interaction were eliminated. All fertile females were remated after they had weaned their first litter to obtain information on litter size in parity two. Line

    Trophectoderm vesicles (TVs) are observed in some blastocysts that penetrate cells from the zona pellucida to the outer margin. Therefore, we compared this incidence in relation to hatching, pregnancy, and miscarriage rates between conventional in vitro fertilization (c-IVF) and intracytoplasmic sperm injection (ICSI). Vitrified/warmed blastocysts (n = 112) were derived from surplus embryos. The blastocysts were then observed using time-lapse cinematography to resolve the relationship between hatching and implantation. Another study was conducted that comprised 681 embryo transfer cycles in 533 patients who received a single vitrified/warmed blastocyst from our clinic. The incidence of TV was significantly higher in embryos inseminated by ICSI compared with c-IVF [ICSI: 51/56 (91 %); c-IVF: 25/56 (45 %); P < 0.01]. The successful hatching rate was significantly lower in ICSI than in c-IVF [ICSI: 11/56 (20 %); c-IVF: 29/56 (52 %); P < 0.01]. In addition, the hatching rate was significantly lower when TVs were present (14/76; 18 %) than in non-TV embryos (26/36; 72 %) (P < 0.01). In regard to the clinical study results, no significant differences were found between the groups in the pregnancy rate (TV present group: 107/183, 58.5 %; TV absent group: 273/498, 54.8 %) and miscarriage rate (TV present group: 21/107, 19.6 %; TV absent group: 53/273, 19.4 %). In vivo, we hypothesized that hatching and hatched would occur naturally by assisting protease action in the uterus; therefore, these results suggest that the presence of TV has no effect on pregnancy rates in the clinical setting.

    The morphological assessment of oocytes is important for embryologists to identify and select MII oocytes in IVF/ICSI cycles. Dysmorphism of oocytes decreases viability and the developmental potential of oocytes as well as the clinical pregnancy rate. Several reports have suggested that oocytes with a dark zona pellucida (DZP) correlate with the outcome of IVF treatment. However, the effect of DZP on oocyte quality, fertilization, implantation, and pregnancy outcome were not investigated in detail. In this study, a retrospective analysis was performed in 268 infertile patients with fallopian tube obstruction and/or male factor infertility. In 204 of these patients, all oocytes were surrounded by a normal zona pellucida (NZP, control group), whereas 46 patients were found to have part of their retrieved oocytes enclosed by NZP and the other by DZP (Group A). In addition, all oocytes enclosed by DZP were retrieved from 18 patients (Group B). No differences were detected between the control and group A. Compared to the control group, the rates of fertilization, good quality embryos, implantation and clinical pregnancy were significantly decreased in group B. Furthermore, mitochondria in oocytes with a DZP in both of the two study groups (A and B) were severely damaged with several ultrastructural alterations, which were associated with an increased density of the zona pellucida and vacuolization. Briefly, oocytes with a DZP affected the clinical outcome in IVF/ICSI cycles and appeared to contain more ultrastructural alterations. Thus, DZP could be used as a potential selective marker for embryologists during daily laboratory work.

    The aim of this study was to determine if an association existed between serum human chorionic gonadotrophin (HCG) level at 12 h after trigger and IVF and intracytoplasmic sperm (ICSI) treatment outcomes. Women undergoing initial IVF-ICSI and embryo transfer treatment using the long luteal phase gonadotrophin-releasing hormone agonist protocol between April 2012 and March 2013 for tubal factor were included (n = 699). In the clinical pregnancy group, HCG after trigger was significantly elevated (276.0 ± 5.1 versus 198.5 ± 6.1 mIU/mL; P < 0.001). The optimal cut-off value proposed by the receiver operating characteristic analysis (area under curve = 0.730) for HCG was 201.2 mIU/ml. Compared with the lower HCG group, the clinical pregnancy rate in the higher HCG group was increased in obese and non-obese patients (77.8% versus 57.3%, P < 0.05; 85.6% versus 53.0%, P < 0.01, respectively). Adjusted for age and body mass index, an increase of HCG was associated with a better IVF-ICSI treatment outcome (OR 4.39, 95% CI 2.99 to 6.45). Clinical pregnancy rate was significantly higher across increasing quartiles of HCG. An elevated level of serum HCG at 12 h after trigger was associated with a better IVF-ICSI outcome.

    The objective of this study was to evaluate, over 2 consecutive years, the effects of acclimation to human interaction on performance, temperament, plasma concentrations of hormones and metabolites, and pregnancy rates of Brahman-crossbred cows. A total of 160 Braford and 235 Brahman x British cows were assigned to the 2-yr study. Approximately 45 d after weaning (August 2006) in yr 1, cows were evaluated for BW, BCS, and temperament (chute score, pen score, and exit velocity), stratified by these measurements in addition to breed and age, and randomly allocated to 14 groups (Braford = 8; Brahman x British = 6). Groups were randomly assigned to the control or acclimation treatment. In yr 2, cows were reevaluated within 45 d after weaning (August 2007) for BW, BCS, and temperament, stratified, and divided into 14 groups similarly as in yr 1, but in such a way that cows received the same treatment assigned in yr 1. Cows were acclimated to human interaction from August to January, and the acclimation process consisted of the same person visiting groups twice weekly and offering approximately 0.05 kg of range cubes per cow (as-fed basis). In January of both years, cow temperament, BW, and BCS were reassessed and cows were exposed to a 90-d breeding season. Blood samples were collected at the beginning of the acclimation period (August) and breeding season (January) for determination of plasma cortisol, IGF-I, and acute phase proteins. A treatment x breed interaction was detected during yr 1 (P < 0.01) for pregnancy analysis because acclimated Braford cows conceived earlier and at a greater percentage (P < 0.01) compared with control cows. According to values obtained at the beginning of breeding and pooled across treatments and breeds, IGF-I concentrations and BCS affected quadratically (P < 0.05), and concentrations of ceruloplasmin and haptoglobin decreased linearly (P < 0.05), the probability of pregnancy during both years.

    The aim of this study was to investigate whether the sperm chromatin structure assay (SCSA) results after swim-up are related to fertilization rates, embryo quality and pregnancy rates following in vitro fertilization (IVF). A total of 223 couples undergoing IVF in our hospital from October 2008 to September 2009 were included in this study. Data on the IVF process and sperm chromatin structure assay results were collected. Fertilization rate, embryo quality and IVF success rates of different DNA fragmentation index (DFI) subgroups and high DNA stainability (HDS) subgroups were compared. There were no significant differences in fertilization rate, clinical pregnancy or delivery rates between the DFI and HDS subgroups. However, the group with abnormal DFI had a lower good embryo rate. So, we concluded that the SCSA variables, either DFI or HDS after swim-up preparation, were not valuable in predicting fertilization failure or pregnancy rate, but an abnormal DFI meant a lower good embryo rate following IVF.

    Low reproductive productivity of young red deer (Cervus elaphus) hinds on New Zealand deer farms appears to reflect high incidences of puberty failure at 16 months of age. This is despite the general attainment of average liveweights 15-25 kg in excess of the accepted minimum threshold for puberty in subspecies of western European origin (scoticus, elaphus and hippelaphus) that form the basis of the national herd. The present study tests the hypotheses that introgression of the larger North American wapiti subspecies (nelsoni, manitobensis and roosevelti) into breeding herds (1) can be assessed from morphological features of individuals, (2) that there is a relationship between the level of wapiti parentage and non-pregnancy rate at 18 months of age (a proxy for puberty failure) and (3) that minimum liveweight thresholds for puberty increase with increasing levels of wapiti parentage. A total of 4329 18-month-old hinds across four "red" deer farms in southern New Zealand were scanned for pregnancy status. Each hind was assigned a wapiti score (WS) as a subjective assessment of the obviousness of wapiti features. Various body measurements were additionally recorded for each hind. A hair sample was collected for DNA analysis (14 markers) to objectively assign subspecies pedigree (i.e. "Elkmeter") on a subset of 1258 individuals. A total of 506 (11.7%) hinds were not pregnant at 18 months of age with rates varying between 4.1 and 37.3% between farms and years. Mean WS differed significantly between farms and reflected the genetic management policy of each farm. WS was positively correlated to Elkmeter for each farm/year (<0.05) although regression slopes varied significantly. WS was able to be adjusted for these differences to assign a corrected WS (CWS) for all 4329 individuals that estimated the proportion wapiti parentage. Discriminant analysis of morphological variables relative to Elkmeter supported the first hypothesis and showed that shoulder height and body

    In this study, the effects of oxytocin and an analog of prostaglandin (cloprostenol) on the uterine involution and pregnancy rates were investigated. Mares received 3 ml of 0.9% NaCl in Group C (n=10), 30 IU/mare of oxytocin in Group O (n=10) and 250 microg/mare of cloprostenol in Group P (n=10) within 12h after parturition. The gravid uterine horn's cross-sectional diameter was measured by ultrasonography. The mean uterine diameters did not differ significantly between the treatment (O and P) and the control (C) groups (p>0.05). The difference between the postpartum ovulation periods (Group C: 12.6+/-0.72 days, Group O: 15+/-1.33 days, Group P: 14.6+/-1.11 days), the pregnancy rates at foal heat (Group C: 60%, Group O: 60%, Group P: 80%) and the embryonic death rates at foal heat (Group C: 33.3%, Group O: 16%, Group P: 25%) were not found to be statistically significant between the treatment and the control groups. The mean progesterone concentrations were similar in all groups and decreased continuously from parturition to until foal heat (Group C: from 2.43+/-0.24 to 0.66 ng/ml, Group O: from 3.07+/-0.6 to 0.27+/-0.27 ng/ml and Group P: from 2.8+/-0.44 to 0 ng/ml) (p>0.05). In conclusion, it was decided that the oxytocin and PGF2alpha treatments performed on the mares with the purpose of stimulating involution had no effect on the duration of parturition-first ovulation, the shrinkage of the uterus diameter, the pregnancy and embryonic death rates.

  13. Does parental consent for birth control affect underage pregnancy rates? The case of Texas.

    Previous work based on conjectural responses of minors predicted that the 2003 Texas requirement for parental consent for state-funded birth control to minors would lead to a large increase in underage pregnancies. We use state- and county-level data to test this prediction. The latter allow us to compare the impact of parental consent in counties with and without state-funded family planning clinics. We control for characteristics systematically correlated with the presence of state-funded clinics by combining difference-in-difference estimation with propensity score-weighted regressions. The evidence suggests that the parental consent mandate led to a large decrease in attendance at family planning clinics among teens but did not lead to an increase in underage pregnancies.

    In this study, we compared pregnancy rates obtained using ram semen stored at 5 °C for 24 h, with ram or bull seminal plasma (SP) added to TRIS-egg yolk extender. During the breeding period, 670 adult Corriedale ewes were cervically inseminated with semen (2 × 10(8) sperm in a volume of 0.2 mL) from eight adult Corriedale rams. Ejaculates, obtained using an artificial vagina, were split into three aliquots and diluted with the following: TRIS-egg yolk based extender (T), T + 30% ram SP (R), or T + 30% bull SP (B). Samples were refrigerated and stored at 5 °C for 24 h until used for AI. Pregnancy was assessed by ultrasonography 35 to 40 d after AI. Pregnancy rate was not affected by ram (P = 0.77) or breeding period (P = 0.43), and there were no interactions between extender and ram (P = 0.94), or extender and breeding period (P = 0.24). However, there was an effect of extender (P = 0.0009) on pregnancy rates; ram SP, but not bull SP, increased pregnancy rates compared with extender without SP (49.7, 38.1, and 31.1%, for R, B, and T respectively). In conclusion, ram SP added to TRIS-egg yolk extender had a beneficial effect on the pregnancy rate of ram sperm stored at 5 °C for 24 h and used for cervical insemination of ewes.

  15. Green tea polyphenols added to IVM and IVC media affect transcript abundance, apoptosis, and pregnancy rates in bovine embryos.

    Three experiments were conducted to examine the effects of green tea polyphenols (GTP) during IVM and IVC on apoptosis and relative transcript abundance (RA) of three genes controlling antioxidant enzymes, as well as subsequent pregnancy rates. In experiment 1, oocytes were matured in the presence of 0, 10, 15, or 25 μM GTP for 24 hours. The GTP dose applied to IVM medium was followed by the same dose supplemented to IVC medium, so oocytes and embryos of a given group were cultured in similar conditions. This resulted in a total of four groups (three experimental groups and the control). After IVF, presumptive zygotes were cultured in medium containing 0 to 25 μM GTP for 8 days. The addition of 15 μM GTP during IVM and IVC increased RA of SOD1, CAT, and GPX genes in blastocysts compared with the control (P < 0.05). Increase in GTP doses from 15 to 25 μM did not further increase the transcript level. In experiment 2, effects of GTP doses on apoptosis were investigated in bovine blastocysts. Two of the applied GTP doses (10 and 15 μM) decreased the apoptotic index (AI) in blastocysts (7.4% and 6.2% respectively) compared with the control (9.3%; P < 0.05). However, the highest GTP dose used (25 μM) caused an increase in AI compared with a dose of 15 μM (P < 0.05). Considering the results of experiment 1 and 2, the effects of 15 μM GTP treatment during IVM and IVC on pregnancy rate was evaluated after embryo transfer in experiment 3. Cows receiving embryos treated with 15 μM GTP had higher pregnancy rates on Day 30 (34.8% vs. 28.6%) and Day 60 (34.8% vs. 23.9%) than those receiving control embryos (P < 0.05). In conclusion, addition of 15 μM GTP during IVM and IVC improved pregnancy rates; this improvement seemed to be associated with the increase of RA of antioxidant enzyme genes and the decrease in AI in bovine blastocysts.

    Background: The use of assisted reproductive technology (ART) is increasing in the world. The rate, efficacy and safety of ART are very different among countries. There is an increase in the use of intra cytoplasmic sperm injection (ICSI), single fresh embryo transfer (ET) and frozen-thawed embryo transfer (FET). Objective: The objective of this study was to compare pregnancy rate in fresh ET and FET. Materials and Methods: In this retrospective cross-sectional study 1014 ICSI-ET cycles (426 fresh ET and 588 FET) from 753 women undergoing ICSI treatment referred to Fatemezahra Infertility and Reproductive Health Research Center in Babol, Iran from 2008 to 2013 were reviewed. Results: There were no significant differences between biochemical pregnancy rate (23% versus 18.8%, OR 1.301; 95% CI .95-1.774), gestational sac (95.6% versus 100% in FET, OR 0.60; 95% CI 0.54-0.67), and fetal heart activity (87.2% versus 93.6% OR .46; 95% CI .16-1.32) in fresh ET and FET cycles, respectively. P< 0.05 was considered statistically significant for all measures. Conclusion: Although, the result showed no significantly difference between the fresh ET and the FET cycles, however the embryos are able to be stored for subsequent ART. Therefore, we recommend FET cycles as an option alongside the fresh ET. PMID:27141547

    Although embryo transfer technology has been used commercially in cattle for many years, the inefficiency of oestrus detection, especially in recipients, has limited the widespread application of this technology. The most useful alternative to increase the number of recipients utilised in an embryo transfer program is the use of protocols that allow for embryo transfer without the need for oestrus detection, usually called fixed-time embryo transfer (FTET). Most current FTET protocols are based on progestin-releasing devices combined with oestradiol or GnRH, which control and synchronise follicular wave dynamics and ovulation. Conception rates to a single FTET have been reported to be similar to those after detection of oestrus, but pregnancy rates are higher because these treatments have increased the proportion of recipients that receive an embryo. Recent changes to treatments for FTET, such as the administration of eCG, have resulted in increased pregnancy rates and provide opportunities to make these treatments easier to perform on farm.

    Maternal diazepam medication during labor reduces beat-to-beat variability of the fetal heart rate. In this study, the prolongation of the effect was examined in the newborn. The mother received diazepam: (A) during labor as a tranquilizer, (B) daily in low doses at the end of pregnancy, or (C) in high doses i.v. for (pre-)eclampsia. A control group had no analgesic or sedative during pregnancy or labor. The electrocardiogram (ECG) was recorded daily from each newborn during the first 6 days after birth. After preprocessing of the ECG, the median R-R interval, the long-term irregularity index (LTI index) and the interval difference index (ID index) were calculated. A cubic spline interpolation method was applied to compare the various groups with respect to these heart rate parameters. The median R-R interval showed no particular differences in trend for all groups. The LTI index was decreased in the first days after birth in the chronic diazepam (B), and in the diazepam infusion groups (C), but statistical significance was not reached. The ID index was significantly decreased in the first 1-2 days in the newborns of the acute and chronic diazepam group. In the diazepam infusion group, an even longer lasting effect was observed. Maternal diazepam medication affects the beat-to-beat variability in the newborn. The duration of the effect is dependent on dosage and route of administration.

    Advanced maternal age is an important predisposing factor on the reduction of reproductive efficiency. The aim of this study was to evaluate the effect of donor's age on several reproductive parameters in a commercial equine embryo transfer program. Donors were classified into 3 age groups: Group 1=fillies (3 and 4 years old), Group 2=middle age mares (aged 5-10) and Group 3=old mares (aged 13-25). Embryo recovery, multiple ovulation and pregnancy rates and interovulatory intervals were compared amongst age groups. Group 1 (171/244, 70.1%) and Group 2 (774/1081, 71.6%) had a higher (P<0.005) embryo recovery rate than Group 3 (385/701, 54.9%). Groups 2 and 3 were 2.5 and 3.4 times more likely to have multiple ovulations than Group 1 (P<0.05), respectively. The effect of age group on pregnancy rate was not significant (P>0.05). The interovulatory intervals length was influenced by individual mare (P<0.001), age (P<0.04), Day of flushing (P=0.009) and by month (P<0.012). The overall mean interovulatory interval of Group 1 (16.4±0.17 days) and Group 2 (16.6±0.12 days) was not different (P>0.05), but was shorter than the one of Group 3 (17.4±0.15 days; P<0.04). The embryo recovery rate of flushings from Groups 1 and 2 was influenced by the length of the previous interovulatory interval (P=0.03).

    The objective of this study was to evaluate the effects of equine chorionic gonadotropin (eCG) treatment on the number of induced accessory corpora lutea (CL), plasma progesterone concentrations and pregnancy rate in cross-bred heifers after transfer of frozen-thawed (1.5M ethylene glycol) embryos. All recipients received 500 microg PGF2alpha (dl-cloprostenol, i.m.) at random stages of the estrous cycle (Day 0) and were observed for estrus for 7 days. On Day 14, heifers detected in estrus between 2 and 7 days after PGF2alpha treatment were randomly allocated to four groups ( n=83 per group) and given 0 (control), 200, 400, or 600 IU of eCG. Two days later (Day 16), these recipients were given PGF2alpha and observed for estrus. Six to eight days after detection of estrus, plasma samples were collected to determine progesterone concentration and ultrasonography was performed to observe ovarian structures. Heifers with multiple CL or a single CL >15 mm in diameter received an embryo by direct transfer. Embryos of excellent and good quality were thawed and transferred to the recipients by the same veterinarian. Pregnancy was diagnosed by ultrasonography and confirmed by transrectal palpation 21 and 83 days after embryo transfer (ET), respectively. Plasma progesterone concentrations on the day of transfer (Day 7 of the estrous cycle) were 3.9+/-0.7, 4.2+/-0.4,6.0+/-0.4 and 7.8+/-0.6 ng/ml for groups Control, 200, 400, and 600, respectively (Control versus treated groups P=0.009; 200 versus 400 and 600 groups P=0.0001; and 400 versus 600 P=0.012 ). Conception rates 83 days after ET were 41.9, 50.0, 25.0, and 20.9% for groups Control, 200, 400, and 600, respectively (200 versus 400 and 600 groups P=0.0036 ). In conclusion, an increase in progesterone concentration, induced by eCG treatment, did not improve pregnancy rates in ET recipients. Conversely, there was a decline in conception rates in the animals with the highest plasma progesterone concentrations.

    In social insects, newly emerged individuals learn the colony-specific chemical label from their natal comb shortly after their emergence. These labels help to identify each individual's colony of origin and are used as a recognition template against which individuals can discriminate nestmates from non-nestmates. Our previous studies with Polybia paulista von Ihering support this general pattern, and the acceptance rate of young female and male wasps decreased as a function of their age. Our study also showed in P. paulista that more than 90% of newly emerged female wasps might be accepted by conspecific unrelated colonies. However, it has not been investigated whether the acceptance rate of newly emerged female wasps depends on colony developmental stage of recipient colonies. We introduced newly emerged female wasps of P. paulista into different colony developmental stags of recipient colonies, i.e., worker-producing and male-producing colonies. We found that the acceptance rate of newly emerged female wasps by alien colonies was pretty lower by male-producing colonies than worker-producing colonies. This is the first study to show that the acceptance rate of young female wasps depends on stages of recipient colonies.

    Introduction: Acceptance rate of postpartum intrauterine contraceptive device (PPIUCD) offered through a public health approach is unknown. Our aim was to describe the acceptance rate, expulsion, and follow-up and factors associated with it when PPIUCD was offered to women delivering at two primary health centers (PHCs). Methods: We analyzed routine health data of deliveries at two PHCs in district Faridabad, India between May and December 2014, having sociodemographic variables, obstetric history, and during the follow-up check-up at 6-weeks postpartum for in situ status of intrauterine contraceptive device, side effects, and complications. Results: The overall acceptance rate among those eligible for PPIUCD was 39% (95% confidence interval [CI]: 35.1–42.9). Independent predictor of acceptance was a monthly family income of rate, and removal rate at 6 weeks postpartum was 18.0% and 13.0%, respectively. Expulsion by 6 weeks was associated with, age >25 years (O.R.: 2.21, 95% CI: 1.03–4.73), gravida ≥4 (O.R.: 4.01, 95% CI: 1.28–12.56), and a living previous-child (O.R.: 1.51, 95% CI: 1.04–2.19). Conclusion: Acceptance rate of PPIUCD was higher than that reported in literature. Women from lower income family, having at least one living child, and having attended antenatal care clinic were more likely to accept PPIUCD. PMID:28348988

    DHA (22:6n-3) supplementation during infancy has been associated with lower heart rate (HR) and improved neurobehavioral outcomes. We hypothesized that maternal DHA supplementation would improve fetal cardiac autonomic control and newborn neurobehavior. Pregnant women were randomized to 600 mg/day of DHA or placebo oil capsules at 14.4 (+/-4) weeks gestation. Fetal HR and HRV were calculated from magnetocardiograms (MCGs) at 24, 32 and 36 weeks gestational age (GA). Newborn neurobehavior was assessed using the Neonatal Behavioral Assessment Scale (NBAS). Post-partum maternal and infant red blood cell (RBC) DHA was significantly higher in the supplemented group as were metrics of fetal HRV and newborn neurobehavior in the autonomic and motor clusters. Higher HRV is associated with more responsive and flexible autonomic nervous system (ANS). Coupled with findings of improved autonomic and motor behavior, these data suggest that maternal DHA supplementation during pregnancy may impart an adaptive advantage to the fetus.

    Aim of this study was to test the reliability of Trypan blue/Giemsa staining to evaluate sperm membrane integrity, acrosomal intactness and morphology in stallion to verify whether it could be applied in vitro as useful tool for sperm fertilizing ability. Fertility data on inseminated mares were collected to evaluate the relationship of sperm quality to pregnancy rates. Forty-one ejaculates were collected from 3 stallions of Salernitano Horse Breed and evaluated for gross appearance, volume, visual motility and membrane integrity with Trypan blue/Giemsa staining and thirty-five mares were inseminated during the breeding season from April to July. Differences among stallions were found in volume, sperm concentration (p < 0.05) and visual motility (p < 0.01). A decrease in sperm motility, concentration (p < 0.05) and total sperm number was found in June-July (p < 0.01). Live sperm with intact acrosome (LSIA) and proximal droplets (PD) were lower (p < 0.01) in June-July, while acrosome reacted sperm (ARS) percentage increased (p < 0.05). No fertility differences were found among stallions with an average fertility per cycle of 44.6% and a pregnancy rate of 68.6%. Higher percentages of LSIA were found in the ejaculates used to inseminate mares that became pregnant vs those used in mares not pregnant (p < 0.05). The significance of LSIA as test variable to verify the reliability of Trypan blue/Giemsa staining was confirmed by Receiver operating characteristic ROC analysis and the sensitivity of the test was 85% at a cut-off value of 48% LSIA. Trypan blue-Giemsa showed to be an accurate method that can be applied on field to evaluate sperm membrane integrity and to identify poor-quality ejaculates.

    Objectives Assess mental health outcomes among women raising children from sexual violence-related pregnancies (SVRPs) in eastern Democratic Republic of Congo and stigma toward and acceptance of women and their children. Design Participants were recruited using respondent-driven sampling. Setting Bukavu, Democratic Republic of Congo in 2012. Participants 757 adult women raising children from SVRPs were interviewed. A woman aged 18 and older was eligible for the study if she self-identified as a sexual violence survivor since the start of the conflict (∼1996), conceived an SVRP, delivered a liveborn child and was currently raising the child. A woman was ineligible for the study if the SVRP ended with a spontaneous abortion or fetal demise or the child was not currently living or in the care of the biological mother. Intervention Trained female Congolese interviewers verbally administered a quantitative survey after obtaining verbal informed consent. Outcome measures Symptom criteria for major depressive disorder, post-traumatic stress disorder, anxiety and suicidality were assessed, as well as stigma toward the woman and her child. Acceptance of the woman and child from the spouse, family and community were analysed. Results 48.6% met symptom criteria for major depressive disorder, 57.9% for post-traumatic stress disorder, 43.3% for anxiety and 34.2% reported suicidality. Women who reported stigma from the community (38.4%) or who reported stigma toward the child from the spouse (42.9%), family (31.8%) or community (38.1%) were significantly more likely to meet symptom criteria for most mental health disorders. Although not statistically significant, participants who reported acceptance and acceptance of their children from the spouse, family and community were less likely to meet symptom criteria. Conclusions Women raising children from SVRPs experience symptoms of mental health disorders. Programming addressing stigma and acceptance following sexual violence may

    Objective. To determine the optimal duration of progesterone supplementation prior to transfer of cryopreserved embryos and its impact on implantation and pregnancy rates. Study Design. Prospective randomised study. Materials and Methods. In an IVF unit of a tertiary centre, sixty-six patients undergoing cryopreserved embryo transfer cycles were included. Endometrial preparation was done with estradiol valerate. Once it reached a minimum of 7 mm, patients were allocated randomly into group I (n = 39) and group II (n = 27). Injectable progesterone 100 mg daily was then started for 3 and 4 days, respectively. This was followed by transfer of at least one thawed cleavage stage day 2 embryo of good quality. Groups I and II were compared in terms of clinical pregnancy and implantation rates. Results. In group I (3-day progesterone) and group II (4-day progesterone) the pregnancy rates were 41.02% (16/39) and 18.51% (5/27), respectively. On the other hand, the implantation rates were 16.82% (18/107) and 7.69% (6/78), respectively. The difference was statistically significant (p values 0.0172 and 0.0386, resp.). Conclusion. Progesterone supplementation for three days before the transfer of cleavage stage (day 2) cryopreserved embryos has significantly higher pregnancy and implantation rates, as compared to four-day supplementation.

    This study investigated the effects of gonadotrophin-releasing hormone (GnRH) administration (Experiment 1) and a controlled internal drug-releasing (CIDR) insert (Experiment 2) after timed artificial insemination (TAI) on the pregnancy rates of dairy cows. In Experiment 1, 569 dairy cows that underwent TAI (day 0) following short-term synchronization with prostaglandin F2α were randomly allocated into two groups: no further treatment (control, n = 307) or injection of 100 µg of gonadorelin on day 5 (GnRH, n = 262). In Experiment 2, 279 dairy cows that underwent TAI (day 0) following Ovsynch were randomly allocated into two groups: no further treatment (control, n = 140) or CIDR insert treatment from days 3.5 to 18 (CIDR, n = 139). The probability of pregnancy following TAI did not differ between the GnRH (34.4%) and control (31.6%, p > 0.05) groups. However, the probability of pregnancy following TAI was higher (odds ratio: 1.74, p < 0.05) in the CIDR group (51.1%) than in the control group (39.3%). Overall, CIDR insert treatment at days 3.5 to 18 increased pregnancy rates relative to non-treated controls, whereas a single GnRH administration on day 5 did not affect the pregnancy outcomes of dairy cows.

    Polycystic ovary syndrome (PCOS), affecting more than 5-10% of woman at reproductive childbearing age, is characterized by anovulation and hyperandrogenism. Frozen-thawed embryo transfer (ET) has been widely used for PCOS women to minimize the risk of ovarian hyperstimulation syndrome. However, the hyperandrogenic status of PCOS women deteriorates endometrial function, which has subsequently increased miscarriage rates in PCOS women. Therefore, we conducted this retrospective study to compare the pregnancy outcomes of hyperandrogenic PCOS women with (n = 29) and without (n = 31, controls) pretreatment of gonadotropin-releasing hormone (GnRH) agonist before frozen-thawed ET. We found that pretreatment with GnRH agonist before frozen-thawed ETs could not significantly improve the clinical pregnancy rate in these hyperandrogenic PCOS women. However, the ongoing pregnancy rate was significantly increased in women with GnRH agonist pretreatment (odds ratio: 3.98, 95% confidence interval: 1.12-14.20, p = 0.033). We concluded that androgen deprivation status due to pretreatment with GnRH agonist might improve the ongoing pregnancy rate in hyperandrogenic PCOS women. Additional large, well-designed prospective studies are worthwhile and necessary.

    Background: Clomiphene citrate (CC) is the first line agent used for ovulation induction in patients with polycystic ovarian syndrome (PCOS). However, there is marked discrepancy between the ovulation and pregnancy rates achieved, which may be attributed to the undesirable effect of CC on cervical mucus and endometrium. Objective: The aim of this study was to evaluate the effect of Isosorbid monoitrate (ISMN) as nitric oxide (NO) donors on the ovulation and pregnancy rates in an ovulatory women with PCOS treated with CC. Materials and Methods: Ninety patients with PCOS were randomly allocated into three groups. Patients in group A) were treated with 100 mg CC for five days starting from the fifth day of the cycle. Patients in group B) and C) received 10 mg and 20 mg of ISMN respectively in addition to CC, applied vaginally till the diagnosis of ovulation. Results: There was a significant increase in the ovulation and pregnancy rates in the patients treated with CC+ISMN as compared with patients treated with CC alone (p< 0.001). Conclusion: Concomitant use of NO with CC seems to improve the ovulation and pregnancy rates in the patients with PCOS with no significant increase in side effects as compared with CC alone.

    In the area of product design and usability, most products are developed for the mass-market by technically oriented designers and developers for use by persons who themselves are also technically adept by today's standards. The demands of older people are commonly not given sufficient consideration within the early developmental process. In the present study, the usability and acceptability of four different devices meant to be worn for the measurement of heart rate or ECG were analyzed on the basis of qualitative subjective user ratings and structured interviews of twelve older participants. The data suggest that there was a relatively high acceptance concerning these belts by older adults but none of the four harnesses was completely usable. Especially problematic to the point of limiting satisfaction among older subjects were problems encountered while adjusting the length of the belt and/or closing the locking mechanism. The two devices intended for dedicated heart rate recording yielded the highest user ratings for design, and were clearly preferred for extended wearing time. Yet for all the devices participants identified several important deficiencies in their design, as well as suggestions for improvement. We conclude that the creation of an acceptable monitoring device for older persons requires designers and developers to consider the special demands and abilities of the target group.

    The climate of Central America is highly variable both spatially and temporally; extreme events like floods and droughts are recurrent phenomena posing great challenges to regional water-resources management. Scarce and low-quality hydro-meteorological data complicate hydrological modelling and few previous studies have addressed the water-balance in Honduras. In the alluvial Choluteca River, the river bed changes over time as fill and scour occur in the channel, leading to a fast-changing relation between stage and discharge and difficulties in deriving consistent rating curves. In this application of a four-parameter water-balance model, a limits-of-acceptability approach to model evaluation was used within the General Likelihood Uncertainty Estimation (GLUE) framework. The limits of acceptability were determined for discharge alone for each time step, and ideally a simulated result should always be contained within the limits. A moving-window weighted fuzzy regression of the ratings, based on estimated uncertainties in the rating-curve data, was used to derive the limits. This provided an objective way to determine the limits of acceptability and handle the non-stationarity of the rating curves. The model was then applied within GLUE and evaluated using the derived limits. Preliminary results show that the best simulations are within the limits 75-80% of the time, indicating that precipitation data and other uncertainties like model structure also have a significant effect on predictability.

    Objective To determine the preferred regimen for women with adenomyosis undergoing in vitro fertilization (IVF), we compared the IVF outcomes of fresh embryo transfer (ET) cycles with or without gonadotropin-releasing hormone (GnRH) agonist pretreatment and of frozen-thawed embryo transfer (FET) cycles following GnRH agonist treatment. Methods This retrospective study included 241 IVF cycles of women with adenomyosis from January 2006 to January 2012. Fresh ET cycles without (147 cycles, group A) or with (105 cycles, group B) GnRH agonist pretreatment, and FET cycles following GnRH agonist treatment (43 cycles, group C) were compared. Adenomyosis was identified by using transvaginal ultrasound at the initial workup and classified into focal and diffuse types. The IVF outcomes were also subanalyzed according to the adenomyotic region. Results GnRH agonist pretreatment increased the stimulation duration (11.5±2.1 days vs. 9.9±2.0 days) and total dose of gonadotropin (3,421±1,141 IU vs. 2,588±1,192 IU), which resulted in a significantly higher number of retrieved oocytes (10.0±8.2 vs. 7.9±6.8, p=0.013) in group B than in group A. Controlled ovarian stimulation for freezing resulted in a significantly higher number of retrieved oocytes (14.3±9.2 vs. 10.0±8.2, p=0.022) with a lower dose of gonadotropin (2,974±1,112 IU vs. 3,421±1,141 IU, p=0.037) in group C than in group B. The clinical pregnancy rate in group C (39.5%) tended to be higher than those in groups B (30.5%) and A (25.2%) but without a significant difference. Conclusion FET following GnRH agonist pretreatment tended to increase the pregnancy rate in patients with adenomyosis. Further large-scale prospective studies are required to confirm this result.

    The winter diet of barren-ground caribou may affect adult survival, timing of parturition, neonatal survival, and postpartum mass. We used microhistological analyses and hormone levels in feces to determine sex-specific late-winter diets, pregnancy rates, group composition, and endocrine-based measures of physiological and nutritional stress. Lichens, which are highly digestible but contain little protein, dominated the diet (> 68%) but were less prevalent in the diets of pregnant females as compared to non-pregnant females and males. The amount of lichens in the diets of pregnant females decreased at higher latitudes and as winter progressed. Pregnancy rates (82.1%, 95% CI = 76.0 - 88.1%) of adult cows were within the expected range for a declining herd, while pregnancy status was not associated with lichen abundance in the diet. Most groups (80%) were of mixed sex. Male: female ratios (62:100) were not skewed enough to affect the decline. Levels of hormones indicating nutritional stress were detected in areas of low habitat quality and at higher latitudes. Levels of hormones indicated that physiological stress was greatest for pregnant cows, which faced the increasing demands of gestation in late winter. These fecal-based measures of diet and stress provided contextual information for the potential mechanisms of the ongoing decline. Non-invasive techniques, such as monitoring diets, pregnancy rates, sex ratios and stress levels from fecal samples, will become increasingly important as monitoring tools as the industrial footprint continues to expand in the Arctic.

    Background: Implantation is one of the essential steps for the success of assisted reproductive techniques (ART). Their success depends on three main factors: embryo quality, endometrial receptivity (ER), and synchrony between embryo and endometrium. There are various factors that regulate the complex process of implantation. In this regard, one may refer to human chorionic gonadotropin (hCG) as the most important factor. Objective: This study aims to investigate the effect of intrauterine hCG injection before embryo transfer (ET) on pregnancy outcome in infertile couples. Materials and Methods: A total of 159 patients undergone In vitro Fertilization/ Intracytoplasmic Sperm Injection (IVF/ICSI) with an antagonist protocol were evaluated. Patients were divided into three groups (n=53). Group 1 received 500 IU of hCG, group 2 received 1000 IU of hCG intrauterine injection before ET, and the control group underwent ET without hCG preceding intrauterine injection. Results: There was no significant difference among the groups. The implantation rates were 18.86%, 13.52%, and 14.37%, chemical pregnancy rates were 34%, 32.1%, and 35.3%, and clinical pregnancy rates were 34%, 32.1%, and 31.4% respectively. Conclusion: The pregnancy outcome in IVF/ICSI /ET cycles cannot be improved through hCG intrauterine injections before ET. PMID:27921090

    There is an ongoing debate whether tubal ectopic pregnancy should be treated by salpingotomy or salpingectomy. It is unknown which treatment women prefer in view of the potentially better fertility outcome but disadvantages of salpingotomy. This study investigated women surgically treated for tubal ectopic pregnancy and subfertile women desiring pregnancy and their preferences for salpingotomy relative to salpingectomy by means of a web-based discrete choice experiment consisting of 16 choice sets. Scenarios representing salpingotomy differed in three attributes: intrauterine pregnancy (IUP) chance, risk of persistent trophoblast and risk of repeat ectopic pregnancy. An 'opt out' alternative, representing salpingectomy, was similar for every choice set. A multinomial logistic regression model was used to analyse relative importance of the attributes. This study showed that the negative effect of repeat ectopic pregnancy was 1.6 times stronger on the preference of women compared with the positive effect of the spontaneous IUP rate. For all women, the risk of persistent trophoblast was acceptable if compensated by a small rise in the spontaneous IUP rate. The conclusion was that women preferred avoiding a repeat ectopic pregnancy to a higher probability of a spontaneous IUP in the surgical treatment of tubal ectopic pregnancy. An ectopic pregnancy occurs when a fertilized egg gets stuck inside the Fallopian tube where it starts growing instead of passing on to the uterus. This may lead to serious problems, such as internal bleeding and pain. Therefore, in the majority of women, it is necessary to remove the ectopic pregnancy by means of an operation. Two types of surgery are being used in removing the ectopic pregnancy. A conservative approach, salpingotomy, preserves the tube but bears the risk of incomplete removal of the pregnancy tissue (persistent trophoblast), which then needs additional treatment, and of a repeat ectopic pregnancy in the same tube in the

    Advanced paternal age has been associated with a variety of rare conditions and diseases of great public health impact. An increased number of de novo point mutations in sperm with increasing age have been suggested as a mechanism, which would likely also affect fetal viability. We examined the association between paternal age and stillbirth rate in a large nationwide cohort. We identified all pregnancies in Denmark from 1994 to 2010 carried to a gestational age of at least 22 completed weeks (n = 944,031) as registered in national registers and linked to individual register data about the parents. The hazard ratio of stillbirth according to paternal age was estimated, adjusted for maternal age in 1-year categories, year of outcome, and additionally parental educational levels. The relative rate of stillbirth (n = 4946) according to paternal age was found to be J-shaped with the highest hazard ratio for fathers aged more than 40 years when paternal age was modelled using restricted cubic splines. When modelled categorically, the adjusted hazard ratios of stillbirth were as follows: <25, 1.16 (95% confidence interval, CI 1.01-1.34); 25-29, 1.03 (95% CI 0.95-1.11); 35-39, 1.16 (95% CI 1.07-1.26); 40-44, 1.41 (95% CI 1.26-1.59); 45-49, 1.20 (95% CI 0.97-1.49); 50+, 1.58 (95% CI 1.18-2.11), compared with fathers aged 30-34 years. These estimates attenuated slightly when further adjusted for parental education. Our study showed that paternal age was associated with the relative rate of stillbirth in a J-shaped manner with the highest hazard ratios among fathers aged more than 40 years.

    Field trials were conducted to increase fertility with AI of flow-sorted, sexed bovine sperm. In the first trial, a novel competitive fertilization approach was used to compare pressures (30psi vs 50psi) for sorting sperm. Both X- and Y-sperm were sorted to approximately 95% purity at 30 and at 50psi; X-50+Y-30 (and the converse) were mixed in equal numbers for AI of heifers. Fetal sex divulged which treatment produced the pregnancy; 82% of pregnancies resulted from the 30psi treatment (P<0.05). Based on a similar approach, a new-pulsed laser did not damage sperm any more than the previous standard continuous wave laser. In a large field trial, sorting sperm at 40psi increased pregnancy rates in heifers relative to 50psi (42.3% vs 34.1%, n=367/group, P<0.05). Storing sperm for 20h before sorting at 40psi decreased pregnancy rates from 42.3% (n=367) to 36.8% (n=368; P<0.05). Breeding heifers with sexed sperm 55-56h after CIDR removal and PGF(2alpha) resulted in 34% (n=32) pregnant, compared to 49% (n=35) with fixed-time insemination 67-68h after CIDR removal (P>0.1). Lactating dairy cows pre-screened for normal reproductive tracts when OvSynch injections (GnRH, prostaglandin, GnRH) were initiated, had similar (P>0.1) pregnancy rates to timed AI, with 10x10(6) sexed sperm (43.9%, n=57), 2x10(6) sexed sperm (40.5%, n=57) and 10x10(6) unsexed control sperm (55.6%, n=58). A final field trial with unselected, lactating dairy cows resulted in similar pregnancy rates for 2x10(6) sexed sperm in 0.25mL straws (25.0%, n=708) and 0.5mL straws (24.4%, n=776), but lower (P<0.05) than unsexed control sperm (37.7%, n=713). Younger cows and those >84 days in milk had the highest pregnancy rates for both sexed and unsexed sperm. These studies improved sperm sexing procedures, and provided insight into appropriate commercial use of sexed sperm.

    Data from a large, international, multicenter, randomized trial were analyzed to compare the acceptability of two nonoxynol-9 spermicide preparations. Women who wished to use a spermicide for contraception were randomly assigned to use either a foaming tablet (n = 383) or a nonoxynol-9 film (n = 382) for 28 weeks as their only method of contraception. Participants completed questionnaires about acceptability of the assigned product 4 weeks after admission and at discontinuation. Women in both groups had very favorable opinions of the spermicide. The proportion of women who said that they liked their assigned product very much was 50% in the tablet group and 55% in the film group. Significantly more women in the film group rated the spermicide difficult to insert and stated that the product stuck to the finger during insertion. More women in the tablet group said that the product was messy and that, at least once, it did not dissolve. In both groups, liking the product was significantly associated with consistency of use, but not with subsequent pregnancy. Participants' male partners had little influence on participants' opinions about, or use of, the spermicides. Although previous analyses showed that both spermicides are associated with high pregnancy rates, they are both highly acceptable to most women.

    The advent of sentinel lymph node biopsy has revolutionised surgical management of axillary nodal disease in patients with breast cancer. Patients undergoing neo-adjuvant chemotherapy for large breast primary tumours may experience complete pathological response on a previously positive sentinel node whilst not eliminating the tumour from the other lymph nodes. Results from 2 large prospective cohort studies investigating sentinel lymph node biopsy after neo-adjuvant chemotherapy demonstrate a combined false negative rate of 12.6-14.2% and identification rate of 80-89% with the minimal acceptable false negative rate and identification rate being set at 10% and 90%, respectively. A false negative rate of 14% would have been classified as unacceptable when compared to the figures obtained by the pioneers of sentinel lymph node biopsy which was 5% or less.

  8. Teenage pregnancy.

    1998-03-01

    Pregnancy among women under age 15 years is unusual, but not rare. About one third of the approximately 3 million total pregnancies which occur each year in the US are to teenagers. However, only about 30% of all pregnant adolescents receive adequate prenatal care, even though it is women in that age group who most need such care. Teen mothers have a higher rate of anemia and pregnancy-induced hypertension, most probably related to diet. Infants born to teen mothers are more likely to be premature and of low birth weight. Infants born to teen mothers are also more predisposed to mental retardation, brain damage, and birth injuries. Teen mothers are more likely to have poor weight gain, premature labor, abruptio placentae, and preeclampsia. The psychosocial reasons why teenage women become pregnant are considered, as well as the relevant media influences. While teenage pregnancy remains a major problem in the US, 1996 statistics indicate an overall 4% decline to 54.7 births/1000 among women aged 15-19 years. Teenage women need to be taught that there are many options in life other than pregnancy.

    The objective of this study was to determine the effect of the interval from induced luteolysis to ovulation on fertility of mares from two different farms. At farm 1, 215 mares were inseminated with frozen/thawed semen during 513 estrous cycles over seven consecutive breeding seasons. Estrus was induced with analogues of PGF2α in 179 cycles. At farm 2, 375 embryo flushings were performed in 65 donor mares inseminated with fresh semen; of which, 327 were performed following artificial insemination after PGF-induced luteolysis. In both farms, the intervals from PGF treatment to ovulation (ITO) data were divided into three interval groups: less than 6 days, 6 to 8 days, and greater than 8 days. A mixed regression model was created to determine the effect of different factors on the pregnancy rate (PR) and embryo recovery rate (ERR). Of all factors analyzed, the ITO was the only one that significantly influenced the PR and ERR (P < 0.05). In farm 1, the PR of mares with an ITO of less than 6 days, 6 to 8 days, and greater than 8 days was 26.6%, 39.4%, and 55.9%, respectively (P = 0.01). The PR for mares inseminated after spontaneous luteolysis (without PGF) was 42.5%. In farm 2, the ERR of donor mares for the same ITO groups was 55.0%, 62.6%, and 73.7%, respectively (P = 0.02). The ERR for mares flushed after a previous spontaneous estrus was 75.0%. In conclusion, the ITO had a significant effect on the PR and ERR in the mare. Fertility was reduced as the ITO became shorter.

    Recent studies have proposed that, in women affected by the polycystic ovary syndrome (PCOS), aging is able to regularize the menstrual cyclicity. To evaluate the ovarian response in PCOS patients according to their age, we studied 33 PCOS patients, 20 of whom with an age ranging from 28 to 34 years (younger PCOS) and 13 ranging from 35 to 45 years (older PCOS). All patients underwent an ovulation induction therapeutic protocol with low-dose recombinant follicle stimulating hormone, for a total of 80 cycles (44 cycles for the younger PCOS group and 36 cycles for the older PCOS group). No significant difference was found between the days of therapy (12.3 +/- 5.4 vs. 13.5 +/- 5.6 days), total amount of drugs (980.7 +/- 568.9 IU vs. 1063.9 +/- 469.5 IU) or ovulation rate (93% vs. 89%) in the two groups. The two groups showed a significant difference in the maximum estradiol level (2053.5 +/- 1497.2 vs. 1269.0 +/- 911.5 pmol/l, p < 0.01), the number of the recruited and preovulatory follicles (1.7 +/- 2.5 vs. 0.64 +/- 0.9, p < 0.05 and 1.7 +/- 1.1 vs. 1.2 +/- 0.5, p < 0.01, respectively) and the pregnancy rate (36% vs. 14%, p < 0.05). In conclusion, our data clearly showed that, also in PCOS, advanced age is a negative prognostic factor in the ovarian response to ovulation induction therapies.

    The aim of this study was to document some epidemiological features of termination of pregnancy for birth defects in Iran. We studied 603 pregnant women who were diagnosed/recommended for the termination of pregnancy as having a fetus with some types of birth defect(s). Most women (87.2 percent) had at least one ultrasound examination. The proportion of other screening tests including amniocentesis and genetic tests were 2.8 and 4.6 percent, respectively. Of 603 women, 201 terminated the pregnancy giving a prevalence rate of 33.3 percent (CI 95%: 29.6-37.6). The remaining 402 subjects were unable to get the permission for abortion because of untimely diagnosis/application for termination (20th week of pregnancy and/or later). Forty-eight percent of termination of pregnancies was performed before the 18th week of pregnancy. Neural tube defects, limb deformation, hydrops fetalis, hydrocephaly, and chromosomal anomalies including Down syndrome accounted proportionally for about 65 percent of defects eligible for abortion in the region. Although the rate of termination of pregnancy for birth defects is acceptable at the current situation in the country, more efforts should still be made to convince the community authorities to give more possibility and ease for the termination of pregnancy for congenital anomalies.

    Cytomegalovirus (CMV) screening during pregnancy has been widely discussed for several years, but still no consensus has been agreed. With a number of live births of 750,000 per year in France, we would expect 7500 infected infants at birth per year (rate of congenital infection of 1%). Among infected infants at birth, the number of severely infected foetuses would be approximately 75, the number of infants with severe sequelae would be 480, 675 approximately would present with hearing loss and the number of asymptomatic infants would be 6270. Five different preventive methods for congenital CMV infection are possible: (1) Routine CMV screening at the beginning of pregnancy for primary prevention. (2) Secondary prevention by antenatal diagnosis of congenital CMV infection complications. (3) Tertiary prevention by serological testing during pregnancy. (4) Tertiary prevention by serological screening at birth. (5) Tertiary prevention: Hearing loss screening at birth. The aims of this review are to define the advantages and disadvantages of these different methods of CMV screening during pregnancy and to determine if the current available information would make systematic testing acceptable.

    BACKGROUND Recent systematic reviews of adjuvant acupuncture for IVF have pooled heterogeneous trials, without examining variables that might explain the heterogeneity. The aims of our meta-analysis were to quantify the overall pooled effects of adjuvant acupuncture on IVF clinical pregnancy success rates, and evaluate whether study design-, treatment- and population-related factors influence effect estimates. METHODS We included randomized controlled trials that compared needle acupuncture administered within 1 day of embryo transfer, versus sham acupuncture or no adjuvant treatment. Our primary outcome was clinical pregnancy rates. We obtained from all investigators additional methodological details and outcome data not included in their original publications. We analysed sham-controlled and no adjuvant treatment-controlled trials separately, but since there were no large or significant differences between these two subsets, we pooled all trials for subgroup analyses. We prespecified 11 subgroup variables (5 clinical and 6 methodological) to investigate sources of heterogeneity, using single covariate meta-regressions. RESULTS Sixteen trials (4021 participants) were included in the meta-analyses. There was no statistically significant difference between acupuncture and controls when combining all trials [risk ratio (RR) 1.12, 95% confidence interval (CI), 0.96–1.31; I2 = 68%; 16 trials; 4021 participants], or when restricting to sham-controlled (RR 1.02, 0.83–1.26; I2 = 66%; 7 trials; 2044 participants) or no adjuvant treatment-controlled trials (RR 1.22, 0.97–1.52; I2 = 67%; 9 trials; 1977 participants). The type of control used did not significantly explain the statistical heterogeneity (interaction P = 0.27). Baseline pregnancy rate, measured as the observed rate of clinical pregnancy in the control group of each trial, was a statistically significant effect modifier (interaction P < 0.001), and this covariate explained most of the heterogeneity of the

    A dynamic codeword transition ECC scheme is proposed for highly reliable solid-state drives, SSDs. By monitoring the error number or the write/erase cycles, the ECC codeword dynamically increases from 512 Byte (+parity) to 1 KByte, 2 KByte, 4 KByte…32 KByte. The proposed ECC with a larger codeword decreases the failure rate after ECC. As a result, the acceptable raw bit error rate, BER, before ECC is enhanced. Assuming a NAND Flash memory which requires 8-bit correction in 512 Byte codeword ECC, a 17-times higher acceptable raw BER than the conventional fixed 512 Byte codeword ECC is realized for the mobile phone application without an interleaving. For the MP3 player, digital-still camera and high-speed memory card applications with a dual channel interleaving, 15-times higher acceptable raw BER is achieved. Finally, for the SSD application with 8 channel interleaving, 13-times higher acceptable raw BER is realized. Because the ratio of the user data to the parity bits is the same in each ECC codeword, no additional memory area is required. Note that the reliability of SSD is improved after the manufacturing without cost penalty. Compared with the conventional ECC with the fixed large 32 KByte codeword, the proposed scheme achieves a lower power consumption by introducing the "best-effort" type operation. In the proposed scheme, during the most of the lifetime of SSD, a weak ECC with a shorter codeword such as 512 Byte (+parity), 1 KByte and 2 KByte is used and 98% lower power consumption is realized. At the life-end of SSD, a strong ECC with a 32 KByte codeword is used and the highly reliable operation is achieved. The random read performance is also discussed. The random read performance is estimated by the latency. The latency is below 1.5 ms for ECC codeword up to 32 KByte. This latency is below the average latency of 15,000 rpm HDD, 2 ms.

    Time-based rate programs1, enabled by utility investments in advanced metering infrastructure (AMI), are increasingly being considered by utilities as tools to reduce peak demand and enable customers to better manage consumption and costs. There are several customer systems that are relatively new to the marketplace and have the potential for improving the effectiveness of these programs, including in-home displays (IHDs), programmable communicating thermostats (PCTs), and web portals. Policy and decision makers are interested in more information about customer acceptance, retention, and response before moving forward with expanded deployments of AMI-enabled new rates and technologies. Under the Smart Grid Investment Grant Program (SGIG), the U.S. Department of Energy (DOE) partnered with several utilities to conduct consumer behavior studies (CBS). The goals involved applying randomized and controlled experimental designs for estimating customer responses more precisely and credibly to advance understanding of time-based rates and customer systems, and provide new information for improving program designs, implementation strategies, and evaluations. The intent was to produce more robust and credible analysis of impacts, costs, benefits, and lessons learned and assist utility and regulatory decision makers in evaluating investment opportunities involving time-based rates. To help achieve these goals, DOE developed technical guidelines to help the CBS utilities estimate customer acceptance, retention, and response more precisely.

    An experiment was conducted to examine effects of bovine ST (bST) on serum hormone concentrations, pregnancy rates, and offspring performance. Before initiation of a fall breeding period, 75 Rambouillet ewes (68.8 ± 1.5 kg) received an intravaginal insert containing 0.3 g of progesterone (P4) to synchronize onset of estrus. After 12 d, inserts were removed (d 0), and ewes (stratified by BW and age) received either 0 (control, n = 37) or 250 (n = 38) mg of recombinant bST (Posilac, Monsanto, St. Louis, MO, subcutaneously). Ewes were joined with fertile rams 24 h after insert removal. Blood samples were collected from 12 ewes in each treatment group daily from d 0 to 20 after insert removal. Serum IGF-I concentrations were 315 and 437 (± 58) ng/mL in control and bST-treated ewes 2 d after receiving bST (P = 0.02) and remained increased (P < 0.03) in bST-treated ewes throughout the 13-d period (P < 0.05). Serum prolactin (P > 0.10) and estradiol (P = 0.65) were similar between treatments. Serum triiodothyronine (T3) and thyroxine (T4) concentrations were similar (P > 0.20) between treatments from d 0 through 8. Controls had greater (P < 0.04) serum T3 and T4 concentrations than treated ewes did until d 18. Serum P4 was similar (P > 0.10) in control and bST-treated ewes from d 0 through 3 but was increased (P < 0.05) from d 4 to 8 in control ewes. Serum P4 was again similar (P > 0.10) between treatments from d 9 to 20. Serum insulin concentrations were 0.44 and 1.74 (± 0.19) ng/mL in control and bST-treated ewes, respectively, 1 d after receiving bST (P < 0.001) and remained increased (P < 0.03) in bST-treated ewes through d 9 (P < 0.03). Serum glucose was increased (P = 0.003) from d 0 to 10 in bST-treated ewes compared with controls. Thirty-three of 37 (89%) control ewes were pregnant, whereas 27 of 38 (71%) bST-treated ewes were pregnant (P = 0.05). As a percentage of ewes lambing, 61% and 39% of control ewes produced single and twin lambs, respectively, compared

    Heterotopic pregnancy occurs when intrauterine and ectopic pregnancy are concomitant; overall rate rises from 1/30.000 to 1.5/1000 in assisted reproductive technology pregnancies. HIV (human immunodeficiency virus) patients are at increased risk of heterotopic pregnancies due to the greater frequency of assisted reproductive technology and pelvic inflammatory disease. We report the first case of heterotopic pregnancy in HIV woman. PMID:27928504

    The objective of this study was to determine the effect of oestrous synchronization methods on oestrous behaviour, timing of ovulation and pregnancy rate during the breeding and low breeding seasons in Nili-Ravi buffaloes. In Experiment 1, oestrous behaviour and timing of ovulation were determined from (n=34) oestruses. The mean (+/- S.E.M.) time of ovulation after the onset of standing oestrus was greater (P<0.05) in PGF(2alpha)-induced luteolysis (30.6+/-1.5h) compared to Ovsynch buffaloes (15.0+/-0.8h). In Experiment 2, pregnancy rates were compared between two methods of synchronization (detected oestrus and Ovsynch protocol) during the breeding and low breeding seasons. Pregnancy rates of buffaloes bred at detected oestrus (62.5%) or by the Ovsynch protocol (36.3%) during the breeding season did not differ significantly (P>0.05) from those which were inseminated during the low breeding season (55.5%) and (30.4%), respectively. This study demonstrates clearly that (1) timing of ovulation in Nili-Ravi buffalo is about 30h after the onset of standing oestrus and (2) buffaloes can be successfully synchronized with optimum fertility using either PGF(2alpha) alone (detected oestrus) or using (Ovsynch protocol) during low breeding season, to calve during the period when milk availability is short.

    Pregnancy rates following transfer of an in vitro-produced (IVP) embryo are often lower than those obtained following transfer of an embryo produced by superovulation. The purpose of the current pair of experiments was to examine two strategies for increasing pregnancy rates in heat stressed, dairy recipients receiving an IVP embryo. One method was to transfer two embryos into the uterine horn ipsilateral to the CL, whereas the other method involved injection of GnRH at Day 11 after the anticipated day of ovulation. In Experiment 1, 32 virgin crossbred heifers and 26 lactating crossbred cows were prepared for timed embryo transfer by being subjected to a timed ovulation protocol. Those having a palpable CL were randomly selected to receive one (n = 31 recipients) or two (n = 27 recipients) embryos on Day 7 after anticipated ovulation. At Day 64 of gestation, the pregnancy rate tended to be higher (P = 0.07) for cows than for heifers. Heifers that received one embryo tended to have a higher pregnancy rate than those that received two embryos (41% versus 20%, respectively) while there was no difference in pregnancy rate for cows that received one or two embryos (57% versus 50%, respectively). Pregnancy loss between Day 64 and 127 only occurred for cows that received two embryos (pregnancy rate at Day 127=17%). Between Day 127 and term, one animal (a cow with a single embryo) lost its pregnancy. There was no difference in pregnancy rates at Day 127 or calving rates between cows and heifers, but females that received two embryos had lower Day-127 pregnancy rates and calving rates than females that received one embryo (P < 0.03). Of the females receiving two embryos that calved, 2 of 5 gave birth to twins. For Experiment 2, 87 multiparous, late lactation, nonpregnant Holstein cows were synchronized for timed embryo transfer as in Experiment 1. Cows received a single embryo in the uterine horn ipsilateral to the ovary containing the CL and received either 100 microg Gn

    Implantation failure and early pregnancy loss have been reported to be closely related to the quality of mammalian oocytes; however, the pregnant outcome of embryos from in-vitro matured (IVM) oocytes remains unknown. In this study we examined spindle assembly and chromosome segregation during differentiation, and the duration of IVM of mouse oocytes. The resulting implantation and pregnancy outcomes were analyzed to clarify the relationship between the spindle and chromosomes of IVM oocytes and implantation and early pregnancy. Cumulus-enclosed germinal vesicle oocytes were collected and randomly cultured in IVM medium with different IVM durations. One part of IVM oocytes were analyzed the spindle and chromosome morphology by immunofluorescence method, and the other part of them were fertilized by intracytoplasmic sperm injection. The resulting embryos were transferred into pseudo-pregnant female mice, and the post-implantation and full term development was observed. The chromosome aberrations and incorrect spindle assembly seems not affect the early development and blastocyst cell number derived from IVM oocytes, however the development potential of the resulting embryos after implantation were significant decreased with the ratio increasing of chromosome aberrations and incorrect spindle assembly. Accordingly, the full-term development was also decreased. In conclusion, the present study showed the spindle assembly of in vitro-matured oocytes was one of the most important factors that affected the implantation and ongoing pregnancy rates of IVM oocytes, and the improvement by an appropriate duration of maturation in vitro will enhance the post-implantation development potential of the resulting embryos, and decrease implantation failure and early pregnancy loss.

    The objective was to clarify in vitro production of bovine embryos in Brazil. Data from 656 ovum pick-up/in vitro production (OPU/IVP) procedures, performed on 317 Nelore (Bos indicus) donors, without hormone stimulation or control of ovarian follicular waves, were analysed. Donors were subjected to OPU from one to nine times (no specific schedule), with < 15 d between consecutive procedures. There were 20,848 oocytes, of which 15,747 (75.53%) were considered viable, 5,446 embryos were obtained, 5,398 embryos were immediately transferred, resulting in 1,974 pregnancies (36.57%) at Day 30 and 1,788 (33.12%) pregnancies at Day 60. The average number of total and viable oocytes produced per OPU session was (mean ± SEM) 30.84 ± 0.88 and 23.35 ± 0.7 (average of 8.1 ± 0.3 embryos and 3.0 ± 0.1 pregnancies per OPU-IVP procedure). Since oocyte production varied widely among donor, they were designated as very high, high, intermediate, and low, with 58.94 ± 2.04, 32.61 ± 0.50, 22.13 ± 0.50, and 10.26 ± 0.57 oocytes, respectively, produced by 78, 80, 79, and 80 donors. The number of viable oocytes recovered ranged from 0 to 128; since donors with numerous viable oocytes produced many viable embryos and pregnancies, oocyte production was useful for donor selection. However, there was no significant effect of the number of OPU sessions per donor on mean numbers of oocytes produced. In conclusion, we confirmed field reports of high oocyte production by some Nelore donors and demonstrated individual variation in oocyte yield, which was associated with embryo production and pregnancy rates.

    The winter diet of barren-ground caribou may affect adult survival, timing of parturition, neonatal survival, and postpartum mass. We used microhistological analyses and hormone levels in feces to determine sex-specific late-winter diets, pregnancy rates, group composition, and endocrine-based measures of physiological and nutritional stress. Lichens, which are highly digestible but contain little protein, dominated the diet (> 68%) but were less prevalent in the diets of pregnant females as compared to non-pregnant females and males. The amount of lichens in the diets of pregnant females decreased at higher latitudes and as winter progressed. Pregnancy rates (82.1%, 95% CI = 76.0 – 88.1%) of adult cows were within the expected range for a declining herd, while pregnancy status was not associated with lichen abundance in the diet. Most groups (80%) were of mixed sex. Male: female ratios (62:100) were not skewed enough to affect the decline. Levels of hormones indicating nutritional stress were detected in areas of low habitat quality and at higher latitudes. Levels of hormones indicated that physiological stress was greatest for pregnant cows, which faced the increasing demands of gestation in late winter. These fecal-based measures of diet and stress provided contextual information for the potential mechanisms of the ongoing decline. Non-invasive techniques, such as monitoring diets, pregnancy rates, sex ratios and stress levels from fecal samples, will become increasingly important as monitoring tools as the industrial footprint continues to expand in the Arctic.

    Hypopituitarism is a disorder characterized by the deficiency of one or more of the hormones secreted by the pituitary gland. Hypopituitarism patients may present the symptoms of amenorrhea, poor pregnancy potential, infertility, and no production of milk after delivery. Successful pregnancy in hypopituitarism patient is rare because hypopituitarism is associated with an increased risk of pregnancy complications, such as abortion, anemia, pregnancy-induced hypertension, placental abruption, premature birth, and postpartum hemorrhage. Hypopituitarism during pregnancy and perinatal period should be managed carefully. The hormone levels should be restored to normal before pregnancy. GH and HMG-hCG are combined to improve follicular growth and the success rate of pregnancy. Hypopituitary patients must be closely monitored as changes may need to be made to their medications, and serial ultrasound measurements are also necessary for fetal growth assessment. PMID:25663963

Bradburn's (1969) Affect Balance Scale, and measures of general and maternal self-acceptance during the last trimester of pregnancy and again 6 to 8 weeks following childbirth. There was a significant decrease in depression from pre- to postpartum for the total group. Women high in general self-acceptance were less depressed and displayed less negative affect than those low in general self-acceptance. There were no corresponding differences between the high and low maternal self-acceptance groups. Both pre- and postpartum women tended to rate themselves significantly higher for maternal self-acceptance than for general self-acceptance.

What should I tell her, and are there certain options that are better for use during pregnancy? Answer Although more research is required to fully determine the effects of in utero exposure to sugar substitutes, the available data do not suggest adverse effects in pregnancy. However, it is recommended that sugar substitutes be consumed in moderate amounts, adhering to the acceptable daily intake standards set by regulatory agencies. PMID:25392440

    Background Subclinical hypothyroidism (SCH) has been reported to be associated with adverse pregnancy outcomes, however universal screening and treatment is controversial. Objectives Our objectives were to determine population-specific pregnancy reference values (R1) for serum thyroid-stimulating hormone (TSH) and free thyroxine (FT4) at 14 weeks' gestation, along with the prevalence of SCH and thyroid peroxidase antibody (TPOAb). Methods This was a prospective hospital-based cohort study. 1,402 subjects were recruited. Blood samples were obtained from 769 singleton pregnancies due to default between recruitment and scheduled blood draw. The prevalence of SCH was determined using R1, the laboratory non-pregnant reference values (R2) and previously recommended pregnancy reference values (R3). Results R1 for TSH and FT4 was 0.03-3.17 mU/l (mean ± SD, 1.1 ± 0.76) and 8.85-17.02 pmol/l (mean ± SD, 11.96 ± 2.06), respectively. The prevalence of SCH using reference values R1, R2 and R3 was 1.4% (11/769), 0.5% (4/769) and 1.9% (15/769). Prevalence was significantly greater using R3 when compared to R2 (p = 0.011). TPOAb prevalence was 2.6%. A significantly greater prevalence of TPOAb was found in subclinical hypothyroid subjects using all three reference values than in euthyroid subjects (∼25 vs. 2%, p < 0.05). Conclusions These reference values are the first to be reported for an Afro-Caribbean population. Our findings support the use of pregnancy-specific reference values in our population. PMID:25759799

    To determine effects of biostimulation (BIO) and dietary supplementation (BIO+S) on pubertal age and pregnancy rates, Nelore heifers (n=392) were randomly assigned to one of four treatment groups (n=98/group). All animals were in tropical environmental conditions, in the middle-west region of Brazil, grazing in pastures of Brachiaria brizantha, cv. Marandu; Panicum Maximum, cv. Tanzânia and Brachiaria humidícula. The heifers of the BIO group were kept in the presence of bulls while being maintained on pasture; the animals in the BIO+S group were kept in the presence of bulls while being managed on pasture and were fed a diet with greater energy and protein content to produce 0.49 kg of BW gain/day; the animals in control group (the NBIO) were kept away from bulls and under pasture conditions; and the animals in the NBIO+S group were kept away from bulls, were maintained on pasture, and were fed the same diet as the BIO+S group. Heifers were bred at 22-23 months of age, and pregnancy diagnosis was made 45 days after the end of the breeding season. There were differences (P<0.05) between groups regarding pubertal heifers up to 19 months (NPH), final body weight (FBW) and pregnancy rates (P<0.01), with an advantage for the animals in the BIO and BIO+S groups. Although the effect of a diet with greater protein and energy content was not clear in this experiment, the exposure of heifers to a male during the prepubertal period decreased age at the first breeding season, resulting in a significant reduction in age of first pregnancy in Nelore heifers kept under extensive management systems in a tropical environment.

    Objective To examine the shape (functional form) of the association between the rate of gestational weight gain, pre-pregnancy body mass index (BMI), and preterm birth and its subtypes. Design Retrospective cohort study. Setting National reference obstetric centre in Lima, Peru. Population Pregnant women who delivered singleton babies during the period 2006–2009, resident in Lima, and beginning prenatal care at ≤12 weeks of gestation (n = 8964). Methods Data were collected from the centre database. The main analyses consisted of logistic regression with fractional polynomial modelling. Main outcome measures Preterm birth and its subtypes. Results Preterm birth occurred in 12.2% of women, being mostly idiopathic (85.7%). The rate of gestational weight gain was independently associated with preterm birth, and the shape of this association varied by pre-pregnancy BMI. In women who were underweight, the association was linear (per 0.1 kg/week increase) and protective (OR 0.88; 95% CI 0.82–1.00). In women of normal weight or who were overweight, the association was U-shaped: the odds of delivering preterm increased exponentially with rates <0.10 or >0.66 kg/week, and <0.04 or >0.50 kg/week, respectively. In women who were obese, the association was linear, but nonsignificant (OR 1.01; 95% CI 0.95–1.06). The association described for preterm birth closely resembled that of idiopathic preterm birth, although the latter was stronger. The rate of gestational weight gain was not associated with indicated preterm birth or preterm prelabour rupture of membranes. Conclusions In Peruvian pregnant women starting prenatal care at ≤12 weeks of gestation, the rate of gestational weight gain is independently associated with preterm birth, mainly because of its association with idiopathic preterm birth, and the shape of both associations varies by pre-pregnancy BMI.

    Largely because of assisted reproduction, the rate of multifetal pregnancy is rising rapidly in the United States. Accordingly, dietitians are increasingly being called upon to provide nutrition services for these high-risk pregnancies. This article gives an overview of the incidence of and risks associated with multifetal pregnancy and reviews studies that contribute to our knowledge of nutrition and multifetal pregnancy. Practice guidelines for promoting healthy outcomes based on the best available scientific data are suggested. Guidelines for weight gain for twin and triplet pregnancy, dietary intake, and supplement use are included. Suggested practice guidelines for multifetal pregnancy include a positive rate of weight gain early in pregnancy, the use of prepregnancy weight status to determine total weight gain goals in twin pregnancy, a 50-lb weight gain goal for triplet pregnancy, and higher minimal number of servings of foods from several of the Food Guide Pyramid groups. The need for additional information on the effects of nutritional status on the course and outcome of multifetal pregnancy is critical. Preliminary evidence of the benefits of nutrition services suggests that both the incorporation of dietetics services into care programs and additional research on nutrition and multifetal gestation are warranted.

    Bovine embryos (day 5) were cultured to day 10 with or without 100 ng/mL PGF2α in medium supplemented with control; 100 nM Dex; 1,000 U/mL recombinant human leukemia inhibitory factor (rhLIF); or Dex+rhLIF. Although the rates to development to the blastocyst were not significantly different among groups, the hatching rate after additional culture with Dex +/or rhLIF was significantly higher in all supplemented groups than the control (p < 0.05). In the presence of PGF2α, the hatching rate was significantly restored in all supplemented groups relative to the group treated with only PGF2α and the control (p < 0.05). Embryo transfer (ET) was performed with blastocysts (day 7). PGF2α levels of control recipient cows were significantly higher in the circulatory blood samples collected 60 min after ET than in samples collected 60 min before ET (p < 0.005), and were decreased in cows injected with loading medium supplemented with Dex+rhLIF (p < 0.005). Pregnancy rate was significantly higher in the ET group that received supplemented embryo-loading medium than in the non-supplemented control (p < 0.05). The intrauterine administration of Dex and rhLIF at ET prevented increased PGF2α in circulatory blood and resulted in enhanced pregnancy rate. PMID:27030197

    Infertility affects millions of couples worldwide resulting in distress and depression. In the past several decades, in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) have been developed with high efficiency and success rate. The possible effects of gonadotropin administration on follicular metabolism have been discussed but the outcomes remain controversial. The aim of this study was to identify whether serum progesterone on the day of human chorionic gonadotropin (hCG) administration and the ratio of serum progesterone and the number of oocyte retrieved (P/O) had a predictive role for the outcomes of IVF/ICSI. Eight hundred and twenty-five patients were enrolled between January 2012 and December 2012. A positive correlation between progesterone and IVF/ICSI outcomes were found in patients with good ovarian response using receiver operating characteristic (ROC) curve. We found that when progesterone level was higher than 1.04 ng/ml in good ovarian responses, the implantation rate and clinical pregnancy rate were both reduced compared to the rates in patients exhibiting lower progesterone level (progesterone≤1.04 ng/ml). Moreover, the rise of serum progesterone on the day of hCG was negatively correlated with luteinizing hormone (LH) level. This study used 1.04 ng/ml as a definition of progesterone elevation and an adverse effect of serum progesterone rise was observed on clinical pregnancy rate.

    The recently released findings of a large scale study indicate that developed countries which have accepting attitudes toward teenage sexuality and toward the provision of family planning services for adolescents generally have much lower adolescent pregnancy rates than the US; these findings are stimulating renewed efforts to make sex education and family planning services more readily available to adolescents in the US. The study, undertaken by the Alan Guttmacher Institute, consisted of a statistical analysis of factors associated with adolescent fertility in 37 developed countries and an in-depth comparative analysis of the US and 5 other developed countries (Sweden, France, Netherlands, England and Wales, and Canada). The study confirmed that the US had a higher adolescent pregnancy, abortion, and childbirth rate than almost all other developed countries. Among adolescents 15-19 years of age the pregnancy rate in the US was 96/1000. Respective rates for the Netherlands, Sweden, France, Canada, and England and Wales were 14, 35, 43, 44, and 45. The study failed to confirm many commonly proffered explanations for the high US rates. For example, the discrepancy between the US and the other 5 countries cannot be attributed to the high pregnancy rate among black teenagers in the US as the rate for white teenagers alone (83/1000) is much higher than the rate in the other 5 countries. Neither can the high US rate be attributed to the availability of welfare benefits; welfare benefits in the other countries tend to be higher. Nor can the high US rates be attributed to greater recourse to abortion in the other countries (the abortion rate is higher among adolescents in the the US then in the 5 countries) or to to high US unemployment rate (teenage unemployment is a serious problem in all the other countries). Factors which were common to all 5 countries but lacking in the US included an open attitude toward adolescent sexuality, easy access for teenagers to free and

    Many environmental conditions for in vitro embryo production (IVP) systems for cattle have been relatively standardised, e.g. media composition, temperature, pH, water quality, and atmospheric composition. However, little attention has been paid to the quality of ambient laboratory air and the gas environment in incubators. Although a few studies have examined the effects of chemical air contamination on IVP of human embryos, there are no published accounts for domestic animal embryos. Therefore, this study investigated the effects of an intra-incubator carbon-activated air filtration system (CODA) during in vitro culture (IVC) on embryonic development and subsequent pregnancy rate of bovine embryos. Immature cumulus-oocyte-complexes (COCs) were obtained twice-weekly by ultrasonic-guided transvaginal oocyte aspiration. The COCs were matured in TCM199/FCS/LH/FSH, fertilized with frozen-thawed Percoll-separated semen, and subsequently cultured for 7 day in SOFaaBSA. Day 7 embryos were transferred either fresh or frozen/thawed. The experimental design was a 2 x 2 factorial; presumptive zygotes were placed either in a conventional CO(2)-O(2)-N(2) incubator (Control group) or in an identical CO(2)-O(2)-N(2) incubator with a CODA intra-incubator air purification unit (CODA group) for IVC. The embryo production rate at Day 7 was not affected by the CODA air purification unit (23.4 and 24.7% morulae and blastocysts per oocyte for control and CODA, respectively) nor was there any significant effect on embryo stage or quality. However, the pregnancy rate was improved (P=0.043) for both fresh (46.3% versus 41.0%) and frozen/thawed embryos (40.8% versus 35.6%). In conclusion, atmospheric purification by the CODA intra-incubator air purification unit significantly increased pregnancy rate following transfer of in vitro-produced bovine embryos.

    I am proud and honored to accept this award on behalf of the Government of Bangladesh, and the millions of Bangladeshi children saved by oral rehydration solution. The Government of Bangladesh is grateful for this recognition of its commitment to international health and population research and cost-effective health care for all. The Government of Bangladesh has already made remarkable strides forward in the health and population sector, and this was recognized in UNICEF's 1993 "State of the World's Children". The national contraceptive prevalence rate, at 40%, is higher than that of many developed countries. It is appropriate that Bangladesh, where ORS was discovered, has the largest ORS production capacity in the world. It was remarkable that after the devastating cyclone in 1991, the country was able to produce enough ORS to meet the needs and remain self-sufficient. Similarly, Bangladesh has one of the most effective, flexible and efficient control of diarrheal disease and epidemic response program in the world. Through the country, doctors have been trained in diarrheal disease management, and stores of ORS are maintained ready for any outbreak. Despite grim predictions after the 1991 cyclone and the 1993 floods, relatively few people died from diarrheal disease. This is indicative of the strength of the national program. I want to take this opportunity to acknowledge the contribution of ICDDR, B and the important role it plays in supporting the Government's efforts in the health and population sector. The partnership between the Government of Bangladesh and ICDDR, B has already borne great fruit, and I hope and believe that it will continue to do so for many years in the future. Thank you.

    Mycoplasma hominis and Ureaplasma spp. may colonize the human genital tract and have been associated with adverse pregnancy outcomes such as preterm labour and preterm premature rupture of membranes. However, as these bacteria can reside in the normal vaginal flora, there are controversies regarding their true role during pregnancy and so the need to treat these organisms. We therefore conducted a retrospective analysis to evaluate the treatment of genital mycoplasma in 5377 pregnant patients showing symptoms of potential obstetric complications at 25-37 weeks of gestation. Women presenting with symptoms were routinely screened by culture for the presence of these bacteria and treated with clindamycin when positive. Compared with uninfected untreated patients, women treated for genital mycoplasma demonstrated lower rates of premature labour. Indeed preterm birth rates were, respectively, 40.9% and 37.7% in women colonized with Ureaplasma spp. and M. hominis, compared with 44.1% in uncolonized women (Ureaplasma spp., p 0.024; M. hominis, p 0.001). Moreover, a reduction of neonatal complications rates was observed, with 10.9% of newborns developing respiratory diseases in case of Ureaplasma spp. colonization and 5.9% in the presence of M. hominis, compared with 12.8% in the absence of those bacteria (Ureaplasma spp., p 0.050; M. hominis, p <0.001). Microbiological screening of Ureaplasma spp. and/or M. hominis and pre-emptive antibiotic therapy of symptomatic pregnant women in late pregnancy might represent a beneficial strategy to reduce premature labour and neonatal complications.

    The prevalence of hypertensive disorders in pregnancy is increasing. The etiology and pathophysiology of hypertensive disorders in pregnancy remain poorly understood. Hypertensive disorders are a major cause of maternal and perinatal morbidity and mortality. Treatment of hypertension decreases the incidence of severe hypertension, but it does not impact rates of preeclampsia or other pregnancy complications. Several antihypertensive medications are commonly used in pregnancy, although there is a lack of randomized controlled trials. Severe hypertension should be treated immediately to prevent maternal end-organ damage. Appropriate antepartum, intrapartum, and postpartum management is important in caring for patients with hypertensive disorders.

    The objective of this prospective study was to analyse the epidemiology and prognosis of ectopic pregnancy in Senegal. From January 1 to December 31, 1996, 255 ectopic pregnancies were registered. The national rate of ectopic pregnancy was 0.6%. of expected pregnancies. However, rates differed greatly between areas in Senegal, with extremes ranging from 0.85%. in Dakar to 0.32%. in Thiès. The epidemiological profile was that of a young woman-mean age: 23 years old, mean parity=3, admitted with broken ectopic pregnancy (95%). A salpingectomy was performed in all cases. The maternal mortality rate was 1.20%, while morbidity, mainly due to post-operative infection, was found in 2.7% of the cases.

    Introduction Clomiphene citrate is the first-line therapy for ovulation induction in Polycystic Ovarian Syndrome (PCOS). This drug binds and blocks estrogen receptors and thought to have an anti estrogenic effect on endometrium volume, thus may have adverse effect on fertility. Aim This study aimed to compare the effect of Clomiphene citrate plus Estradiol Valerate with Letrozole on endometrial thickness, abortion and pregnancy rate in infertile women with PCOS undergoing ovulation induction. Materials and Methods This was a randomized double blind clinical trial study on 100 women with PCOS, with an endometrial thickness less than 7mm in spite of follicles greater than 18mm after administration of Clomiphene citrate 100mg/d from 3th to 7th day of menstruation. They were randomly divided in two groups. Group A received 100mg Clomiphene citrate from day 3 to day 7 of menstruation and 4 mg Estradiol Valerate after the 8th day of menstruation until 14th day. Group B treated by 5mg Letrozole from day 3 to 7 of menstruation with placebo from 8th to 14th day of menstruation. In both groups endometrial thickness was measured by transvaginal sonography in the 14th day of menstruation. Data were analysed using SPSS Ver.18.0. Results The mean age was 30.34 years in group A and 29.62 years in group B (p=0.381). The number of infertility years in group A was 3.73 years and in group B was 3.85 years. There was no significant relationship statistically between the two groups in terms of mean age and infertility years (p=0.99). Endometrial thickness in group A was 7.26mm and in group B was 8.17 mm. Pregnancy rates in group A and group B was 32% and 16% respectively. There was significant relationship statistically between the two groups in terms of endometrial thickness and pregnancy rates (p=0.021 and p=0.05). There was no abortion in group A and 5 cases had abortion in group B, there was a significant relationship between the two groups statistically (p=0.028). Conclusion

    The objectives were (i) to evaluate the effect of temperament, determined by modified 2-point chute exit and gait score, on artificial insemination (AI) pregnancy rates in beef heifers following fixed time AI and (ii) to determine the effect of temperament on cortisol, substance-P, prolactin and progesterone at initiation of synchronization and at the time of AI. Angus beef heifers (n = 967) at eight locations were included in this study. At the initiation of synchronization (Day 0 = initiation of synchronization), all heifers received a body condition score (BCS), and temperament score (0 = calm; slow exit and walk or 1 = excitable; fast exit or jump or trot or run). Blood samples were collected from a sub-population of heifers (n = 86) at both synchronization initiation and the time of AI to determine the differences in serum progesterone, cortisol, prolactin and substance-P concentrations between temperament groups. Heifers were synchronized with 5-day CO-Synch+ controlled internal drug release (CIDR) protocol and were inseminated at 56 h after CIDR removal. Heifers were examined for pregnancy by ultrasound 70 days after AI to determine AI pregnancy. Controlling for synchronization treatment (p = 0.03), facility design (p = 0.05), and cattle handling facility design by temperament score interaction (p = 0.02), the AI pregnancy differed between heifers with excitable and calm temperament (51.9% vs 60.3%; p = 0.01). The alley-way with acute bends and turns, and long straight alley-way had lower AI pregnancy rate than did the semicircular alley-way (53.5%, 56.3% and 67.0% respectively; p = 0.05). The serum hormone concentrations differed significantly between different types of cattle handling facility (p < 0.05). The cattle handling facility design by temperament group interactions significantly influenced progesterone (p = 0.01), cortisol (p = 0.01), prolactin (p = 0.02) and substance-P (p = 0.04) both at the initiation of

    The influence of short- and long-term (cohort) effects of climate and density on the life-histories of ungulates in temperate regions may vary with latitude, habitat, and management practices, but the life-histories of ungulates in the Mediterranean region are less well known. This study examined the short- and long-term effects of rainfall and absolute density on hinds in two of the southernmost populations of red deer (Cervus elaphus hispanicus) in Europe. One population received supplementary forage. Unlike more northerly latitudes, where red deer hinds lose body mass in winter as a result of adverse weather, in the Spanish populations, hinds did not lose body mass. Hinds in the population that received supplementary forage were heavier and more likely to become pregnant than were the hinds in the unsupplemented population. The likelihood of pregnancy occurring was strongly influenced by hind body mass; the proportion of yearlings that became pregnant was consequently lower in the unsupplemented population than in the population that received supplementary forage. Cohort effects on hind body mass (negative for density and positive for rainfall at birth) and on the probability of pregnancy (negative for density at birth) were apparent only in the unsupplemented population, which implies that supplemental feeding may partially compensate for negative density-dependent factors during early growth, and that supplemented deer hinds may experience reduced selection pressures. These results reflect the particular seasonal variation in the abundance and quality of food in Mediterranean habitats. The delayed effects of climate and density at birth on adult hind body mass and the prevalence of pregnancy probably affects population dynamics and constitutes a mechanism by which cohort effects affect the population dynamics in Iberian red deer. The management of Iberian red deer populations should take into account cohort effects and supplemental feeding practices, which can

    An experiment was conducted to determine whether pregnancy rates following the transfer of in vitro-produced embryos to heat-stressed cows could be improved by 1) culturing embryos in the presence of IGF-I and 2) treating recipients with GnRH. Lactating Holstein cows (n = 260) were synchronized using a timed ovulation protocol. Embryos were produced in vitro and cultured with or without 100 ng/mL of IGF-I. On d 7 after anticipated ovulation (d 0), a single embryo was transferred to all recipients with a palpable corpus luteum (n = 210). A subset of recipients (n = 164) was injected with either GnRH or placebo on d 11. Plasma progesterone concentrations on d 0 and 7 were used to determine the synchrony of recipients. Pregnancy was diagnosed at d 53 and 81 by rectal palpation. Among all recipients, transfer of IGF-I-treated embryos increased pregnancy rate at d 53 (P < 0.05) and tended to increase pregnancy rate at d 81 (P < 0.06). Calving rate also tended to be higher for recipients that received IGF-I-treated embryos (P < 0.07). Among the subset of synchronized recipients (n = 190), pregnancy rate at d 53 and d 81 and calving rate were higher (P < 0.05) for IGF-I-treated embryos. The GnRH tended to increase pregnancy rate at d 53 for all recipients (P < 0.08) and the subset of synchronized recipients (P < 0.10). There were no effects of GnRH (P > 0.10) for pregnancy rate at d 81 and calving rate. The overall proportion of male calves was 64.3%. There was no effect (P > 0.10) of embryo treatment or GnRH on the birth weight or sex ratio of calves. Results of this experiment indicate that treatment of embryos with IGF-I can improve pregnancy and calving rates following transfer of in vitro-produced embryos. Further research is necessary to determine whether the treatment of recipients with GnRH is a practical approach to increase pregnancy rates following in vitro embryo transfer.

    Objective: Repeated implantation failure (RIF) is a condition in which the embryos implantation decreases in the endometrium. So, our aim was to evaluate the effect of local endometrial injury on embryo transfer results. Materials and methods: In this simple randomized clinical trial (RCT), a total of 120 patients were selected. The participants were less than 40 years old, and they are in their minimum two cycles of vitro fertilization (IVF). Patients were divided randomly into two groups of LEI (Local endometrial injury) and a control group (n = 60 in each group). The first group had four small endometrial injuries from anterior, posterior, and lateral uterus walls which were obtained from people who were in 21th day of their previous IVF cycle. The second group was the patients who have not received any intervention. Results: The experimental and control patients were matched in the following factors. Regarding the clinical pregnancy rate, there was no significant difference noted between the experimental and the control group. Conclusion: Local endometrial injury in a preceding cycle does not increase the clinical pregnancy rate in the subsequent FET cycle of patients with repeated implantation failure. PMID:28101111

    Frozen embryo transfer cycles are now common practice, however, various aspects regarding the potential of frozen embryos remain unclear. The main goal of the present study was to assess embryo quality before and after slow freezing procedure, and more specifically blastomere loss and embryo quality as indicator of viability. A single center retrospective analysis of single frozen-thawed embryo replacements (s-FER) was performed. The embryo quality before and after slow freezing and thawing, implantation, and pregnancy rates were recorded. One hundred and twenty seven s-FER were included in the final analysis. The probability of achieving an ongoing pregnancy was significantly associated with embryo quality and the percentage of blastomere loss after thawing. Considering thawed embryos, a non-significant difference in term of implantation rate was observed, regardless to their post-thawing quality and the percentage of blastomeres loss. In conclusion, current data suggest that thawed embryos are capable of implantation regardless of their morphological quality and the degree of cryoinjury sustained.

    Introduction In spite of the widespread use of automation in industry, manual material handling (MMH) is still performed in many occupational settings. The emphasis on ergonomics in MMH tasks is due to the potential risks of workplace accidents and injuries. This study aimed to assess the effect of box size, frequency of lift, and height of lift on maximum acceptable weight of lift (MAWL) on the heart rates of male university students in Iran. Methods This experimental study was conducted in 2015 with 15 male students recruited from Tehran University of Medical Sciences. Each participant performed 18 different lifting tasks that involved three lifting frequencies (1lift/min, 4.3 lifts/min and 6.67 lifts/min), three lifting heights (floor to knuckle, knuckle to shoulder, and shoulder to arm reach), and two box sizes. Each set of experiments was conducted during the 20 min work period using the free-style lifting technique. The working heart rates (WHR) were recorded for the entire duration. In this study, we used SPSS version 18 software and descriptive statistical methods, analysis of variance (ANOVA), and the t-test for data analysis. Results The results of the ANOVA showed that there was a significant difference between the mean of MAWL in terms of frequencies of lifts (p = 0.02). Tukey’s post hoc test indicated that there was a significant difference between the frequencies of 1 lift/minute and 6.67 lifts/minute (p = 0. 01). There was a significant difference between the mean heart rates in terms of frequencies of lifts (p = 0.006), and Tukey’s post hoc test indicated a significant difference between the frequencies of 1 lift/minute and 6.67 lifts/minute (p = 0.004). But, there was no significant difference between the mean of MAWL and the mean heart rate in terms of lifting heights (p > 0.05). The results of the t-test showed that there was a significant difference between the mean of MAWL and the mean heart rate in terms of the sizes of the two boxes (p

    Objective To explore the acceptability, mechanisms and consequences of provider incentives for smoking cessation and breast feeding as part of the Benefits of Incentives for Breastfeeding and Smoking cessation in pregnancy (BIBS) study. Design Cross-sectional survey and qualitative interviews. Setting Scotland and North West England. Participants Early years professionals: 497 survey respondents included 156 doctors; 197 health visitors/maternity staff; 144 other health staff. Qualitative interviews or focus groups were conducted with 68 pregnant/postnatal women/family members; 32 service providers; 22 experts/decision-makers; 63 conference attendees. Methods Early years professionals were surveyed via email about the acceptability of payments to local health services for reaching smoking cessation in pregnancy and breastfeeding targets. Agreement was measured on a 5-point scale using multivariable ordered logit models. A framework approach was used to analyse free-text survey responses and qualitative data. Results Health professional net agreement for provider incentives for smoking cessation targets was 52.9% (263/497); net disagreement was 28.6% (142/497). Health visitors/maternity staff were more likely than doctors to agree: OR 2.35 (95% CI 1.51 to 3.64; p<0.001). Net agreement for provider incentives for breastfeeding targets was 44.1% (219/497) and net disagreement was 38.6% (192/497). Agreement was more likely for women (compared with men): OR 1.81 (1.09 to 3.00; p=0.023) and health visitors/maternity staff (compared with doctors): OR 2.54 (95% CI 1.65 to 3.91; p<0.001). Key emergent themes were ‘moral tensions around acceptability’, ‘need for incentives’, ‘goals’, ‘collective or divisive action’ and ‘monitoring and proof’. While provider incentives can focus action and resources, tensions around the impact on relationships raised concerns. Pressure, burden of proof, gaming, box-ticking bureaucracies and health inequalities were

    Psychological disturbances, including anxiety and depression, are common during human pregnancy. Our objective was to determine whether these maternal disturbances influence cardiovascular responses of the offspring. The psychological status of 231 pregnant women was determined. Offspring (216) of these women were subsequently exposed to a video challenge stress when aged 7-9 years. Heart rate (HR) and blood pressure (BP) of the children were determined at rest, in response to video stress and during subsequent recovery. Children's resting and stress-induced increases in HR (bpm), systolic (SBP, mm Hg) and diastolic (DBP, mm Hg) BP were all greater in children whose mothers reported anxiety during pregnancy. Values (mean±s.d.) for resting HR, SBP and DBP were 75.15±5.87, 95.37±2.72 and 66.39±4.74 for children whose mothers reported no anxiety and an average of 81.62±6.71, 97.26±2.90 and 68.86±2.82 for children whose mothers reported anxiety at any level. Respective values for stress-induced increments in HR, SBP and DBP were 14.83.±2.14, 16.41±1.97 and 12.72±2.69 for children whose mothers reported no anxiety and 17.95±3.46, 18.74±2.46 and 14.86±2.02 for children whose mothers reported any level of anxiety. Effects of maternal depression were less consistent. The effects of maternal anxiety remained in multivariate analyses, which also included children's birth weight. The results indicate a long-term influence of maternal psychological status during pregnancy on the cardiovascular responses to stress among offspring. These effects may contribute to prenatal influences on subsequent health of the offspring.

    The present study evaluated the effect of progesterone supplementation during a double PGF2α injection synchronization protocol on pregnancy per artificial insemination (P/AI) and on the incidence of twin births. Seven hundred and eighty three dairy cows were synchronized with two injections of PGF2α 14 days apart, starting on day 35 postpartum for their first postpartum insemination. Six days before the second PGF2α injection, cows were treated either with a progesterone-releasing intravaginal device (PRID-Delta) and an intramuscular injection of 500mg of progesterone (n=387) or served as control (n=396) and did not receive progesterone treatment. Cows were inseminated 12h after being detected in estrus. Pregnancy was diagnosed 40-45 days later by transrectal palpation. Progesterone administration improved (P<0.05) the percentage of cows detected in estrus in multiparous [(192/255) 75% vs (161/267) 60%], but not in primiparous cows [93/132 (70%) vs 90/129 (70%)]. Progesterone treatment increased P/AI in multiparous [53/192 (28%) vs 27/161 (17%)] but not in primiparous cows [25/93 (27%) vs 29/90 (32%)]. The incidence of twin births tended to be lower (P=0.09) in cows treated with progesterone [1/74 (1%)] than in the control group [4/53 (7%)]. It is concluded that progesterone administration during estrus synchronization with two PGF2α injections in dairy cows improves estral response and increases P/AI in multiparous, but not in primiparous cows, and tended to decrease the incidence of twin births.

    Difficulties in emotion regulation are associated with development and maintenance of psychopathology. Typically, features of emotion regulation are assessed with self-report questionnaires. Heart rate variability (HRV) is an objective measure proposed as an index of emotional regulation capacity. A limited number of studies have shown that self-reported difficulties in emotion regulation are associated with HRV. However, results from prior studies are inconclusive, and an ecological validation of the association has not yet been tested. Therefore, further exploration of the relation between self-report questionnaires and psychophysiological measures of emotional regulation is needed. The present study investigated the contribution of self-reported emotion regulation difficulties on HRV in a student sample. We expected higher scores on emotion regulation difficulties to be associated with lower vagus-mediated HRV (vmHRV). Sixty-three participants filled out the Difficulties in Emotion Regulation Scale and their resting HRV was assessed. In addition, a subsample of participants provided ambulatory 24-h HRV data, in order to ecologically validate the resting data. Correlation analyses indicated that self-reported difficulties in emotion regulation was negatively associated with vmHRV in both resting HRV and 24-h HRV. Specifically, when exploring the contribution of the different facets of emotion dysregulation, the inability to accept negative emotions showed the strongest association with HRV. The results are discussed and need for future research is described.

    The objective was to evaluate the effects of plasma progesterone (P4) concentrations and exogenous eCG on ovulation and pregnancy rates of pubertal Nellore heifers in fixed-time artificial insemination (FTAI) protocols. In Experiment 1 (Exp. 1), on Day 0 (7 d after ovulation), heifers (n = 15) were given 2 mg of estradiol benzoate (EB) im and randomly allocated to receive: an intravaginal progesterone-releasing device containing 0.558 g of P4 (group 0.5G, n = 4); an intravaginal device containing 1 g of P4 (group 1G, n = 4); 0.558 g of P4 and PGF(2α) (PGF; 150 μg d-cloprostenol, group 0.5G/PGF, n = 4); or 1 g of P4 and PGF (group 1G/PGF, n = 3). On Day 8, PGF was given to all heifers and intravaginal devices removed; 24 h later (Day 9), all heifers were given 1 mg EB im. In Exp. 2, pubertal Nellore heifers (n = 292) were treated as in Exp. 1, with FTAI on Day 10 (30 to 36 h after EB). In Exp. 3, pubertal heifers (n = 459) received the treatments described for groups 0.5G/PGF and 1G/PGF and were also given 300 IU of eCG im (groups 0.5G/PGF/eCG and 1G/PGF/eCG) at device removal (Day 8). In Exp. 1, plasma P4 concentrations were significantly higher in heifers that received 1.0 vs 0.588 g P4, and were significantly lower in heifers that received PGF on Day 0. In Exp. 2 and 3, there were no significant differences among groups in rates of ovulation (65-77%) or pregnancy (Exp. 2: 26-33%; Exp. 3: 39-43%). In Exp. 3, diameter of the dominant ovarian follicle on Day 9 was larger in heifers given 0.558 g vs 1.0 g P4 (10.3 ± 0.2 vs 9.3 ± 0.2 mm; P < 0.01). In conclusion, lesser amounts of P4 in the intravaginal device or PGF on Day 0 decreased plasma P4 from Days 1 to 8 and increased diameter of the dominant follicle on Day 9. However, neither of these nor 300 IU of eCG on Day 8 significantly increased rates of ovulation or pregnancy.

    The use of fixed-time artificial insemination (FTAI) provides producers with numerous benefits including the use of superior genetics, shorter breeding and calving seasons, and a more uniform calf crop. However, the cost of implementing FTAI protocols is one of the several drawbacks hindering their use in the beef industry. Potential injection-site lesions from intramuscular injections of the hormones necessary for estrus synchronization are also a cause of concern for carcass quality. The objectives of this experiment were to (1) determine whether or not a twice-used controlled internal drug release (CIDR) device would be effective in an FTAI protocol without adversely affecting pregnancy rate and (2) whether or not the subcutaneous administration of PGF2α affects pregnancy rate. Nulliparous females (n = 99) between 13 and 27 months of age and multiparous cows (n = 43) between 48 and 74 months of age were synchronized for estrus using the 7-day CO-Synch + CIDR protocol. The females were randomly assigned to one of the two treatments: (1) a once-used CIDR (control) or (2) a twice-used CIDR device (treatment) incorporated into their synchronization protocol. The females were also randomly assigned to have their injection of PGF2α administered either intramuscularly or subcutaneously. Blood was taken in a random subset of nulliparous females (n = 52) just before device removal and assayed for concentration of progesterone. The concentration of progesterone was higher (P = 0.01) in the animals that received once-used CIDR devices than that in those received twice-used CIDR devices (3.4 ± 0.5 and 1.4 ± 0.5 ng/mL, respectively). There was no significant effect of parity (P = 0.82), artificial insemination technician (P = 0.60), PGF2α administration (P = 0.83), or treatment (P = 0.67) on pregnancy rates to artificial insemination which were 75.4 ± 6.0% and 71.7 ± 6.4%, for animals that received once- and twice-used CIDR devices, respectively.

    The positive health trends and overall improvement in health status among the US population cause health professionals, human service providers, educators, and policy makers to be encouraged about the fitness of our nation. When taking a closer look at these trends and related changes, however, a dilemma exists among a portion of our population that cannot be dismissed. While the health status of the US population as a whole has steadily improved over the past decades, such progress has not been sustained for adolescents. In fact, adolescence (15 to 21 years of age) is the only age group in which mortality rates have increased over the past decade. One of the principal threats to adolescent health is unwanted pregnancy. More than one million teenage pregnancies occur each year in the United States, 75 percent of which are unintended. Teenage pregnancy is a multifaceted problem that requires multifaceted intervention. It is not just the pregnant teenager's problem either, but may involve up to three generations of family members and a host of other significant relationships. The impact and cost to society can become staggering. If such a great proportion of these pregnancies are unintended, what steps can be taken to offer acceptable and accessible alternatives to adolescents? An assessment of the magnitude of this problem, its impact on the family and society, and the measures implemented to date reveal a major challenge facing our policy makers, health and human service providers, and concerned citizenry.

    Family planning is hailed as one of the great public health achievements of the last century, and worldwide acceptance has risen to three-fifths of exposed couples. In many countries, however, uptake of modern contraception is constrained by limited access and weak service delivery, and the burden of unintended pregnancy is still large. This review focuses on family planning's efficacy in preventing unintended pregnancies and their health burden. The authors first describe an epidemiologic framework for reproductive behavior and pregnancy intendedness and use it to guide the review of 21 recent, individual-level studies of pregnancy intentions, health outcomes, and contraception. They then review population-level studies of family planning's relation to reproductive, maternal, and newborn health benefits. Family planning is documented to prevent mother-child transmission of human immunodeficiency virus, contribute to birth spacing, lower infant mortality risk, and reduce the number of abortions, especially unsafe ones. It is also shown to significantly lower maternal mortality and maternal morbidity associated with unintended pregnancy. Still, a new generation of research is needed to investigate the modest correlation between unintended pregnancy and contraceptive use rates to derive the full health benefits of a proven and cost-effective reproductive technology.

    Background What role should previous cesarean section play in affecting clinical pregnancy outcomes and avoiding the complications of in vitro fertilization? In this article, we focus on elective single-embryo transfer (eSET) versus double-embryo transfer (DET) and assess the clinical efficacy and safety of eSET in patients who have a previous cesarean scar. Material/Methods The pregnancy, delivery, and neonatal outcomes of 130 patients who had a previous cesarean scar and received in vitro fertilization-embryo transfer (IVF-ET) were retrospectively analyzed. The number of transferred embryos was chosen depending on patients’ desire after acknowledging all benefits and risks, including eSET (eSET group, n=56) and DET (DET group, n=74). A total of 101 patients with previous vaginal delivery receiving IVF-ET in the same period were included as a control group. Results The pregnancy rates, multiple birth rates, abortion rates, ectopic pregnancy rates, gestational age at delivery, preterm birth rates, neonatal birth weight, and take-home baby rates were similar between the previous cesarean section group and the previous vaginal delivery group. A previous cesarean section scar did not affect embryo implantation and pregnancy outcomes in IVF. In the eSET and DET groups of previous cesarean section patients, the embryo implantation rates, pregnancy rates, abortion rates, and take-home baby rates were similar. However, the rate of multiple pregnancies reached 50% in the DET group, which led to more preterm births and lower birth weight. Conclusions Elective single-embryo transfer is a well-accepted strategy to avoid multiple pregnancies and improve the obstetric and neonatal outcomes of singleton pregnancy in IVF patients with a previous cesarean section.

    Aims: This study aimed at elucidating the effects of recombinant human follicle stimulating hormone (r-hFSH) on the ovarian follicular dynamics, progesterone, estradiol-17β profiles, and pregnancy of dairy cows. Materials and Methods: Three groups (G, n=5 cows) of multiparous dairy cows were used. G1 (C) control cows were given controlled internal drug release (CIDR) and prostaglandin F2α; G2 (L) cows were given low dose (525 IU and G3 (H) cows were given high dose (1800 IU) of r-hFSH on twice daily basis at the last 3 days before CIDR removal. All cows were ultrasonically scanned for follicular growth and dynamics, and blood samples were collected every other day for two consecutive estrus cycles for the determination of estradiol-17β and progesterone. Results: Estrus was observed in all C and L but not in H cows. Dominant follicle was bigger in L compared to C and H cows. Dominant follicle in C (16.00±2.5 mm) and L cows (17.40±2.3 mm) disappeared at 72 h after CIDR removal. However, in H cows, no ovulation has occurred during 7 days post-CIDR removal. Progesterone was not different (p>0.10) among groups, whereas estradiol-17β revealed significant (p<0.01) reduction in H (15.96±2.5 pg/ml) cows compared to C (112.26±26.1 pg/ml) and L (97.49±15.9 pg/ml) cows. Pregnancy rate was higher in L cows (60%) compared with C cows (20%). However, H cows were not artificially inseminated due to non-ovulation. Only a cow of C group has calved one calf, however, 2 of the L cows gave birth of twins and a cow gave single calf. Conclusion: Administration of a low dose (525 IU) of r-hFSH resulted in an optimal size of dominant follicle, normal values of progesterone and estradiol-17β, and 40% twinning rate, howeverusing 1800 IU of r-hFSH, have adverse effects on ovarian follicular dynamics and hormonal profiles with non-pregnancy of dairy cows raised under hot climate.

    The objectives were to determine the effects of feeding supplements rich in omega-6 or omega-3 fatty acids (FA) during the late gestation to the early postpartum and breeding periods on reproduction and milk FA profile in beef cows. For each of two years, at the beginning of period 1 (mid-December), 72 beef cows, calving in January or February, were assigned to diets supplemented with roasted flaxseed (Flax) or roasted soybean (Soybean). For each of two years, after 11 wk (end of period 1), 18 cows of 36 in the Flax group were switched to the soybean supplement and 18 cows of 36 in the Soybean group were switched to the flax supplement (start of Period 2). Cows were bred by timed artificial insemination (TAI) in week 5 of period 2. The FA composition of the milk reflected the FA profile of the oilseed supplements. There were no differences in pregnancy rates among the 4 groups. The treatments had no effect on plasma prostaglandin metabolite levels or ratios at 4 to 11 d postpartum. At 5 to 6 d post- TAI, pregnant cows fed Flax in period 1 had lower (P < 0.05) plasma prostaglandin F metabolite (PGFM) levels and PGFM to prostaglandin E metabolite (PGEM) ratio than cows fed Soybean, but there were no significant differences at 19 to 20 d post-TAI. Cows pregnant from TAI and fed Flax in period 2 had higher (P < 0.05) serum progesterone levels at 5 to 6 d post-TAI than cows fed Soybean, but there was no difference at 19 to 20 d post-TAI. The dietary treatments had no effect on pregnancy rates, but there were some effects on plasma PGFM levels, PGFM to PGEM ratios, and serum progesterone levels. The FA supplements influenced the FA composition of milk.

    OBJECTIVE: The objective of this study was to evaluate the relationship between oocyte yield, fertilization, and clinical pregnancy (CP), and anti-Mullerian hormone (AMH) level in serum and follicular fluid during in vitro fertilization treatment. METHODS: Forty-four infertile women who underwent IVF treatment using multiagonist protocol were included in this study. Baseline level of AMH in serum and follicular fluid was measured on third day of menstrual cycle. AMH level in serum and follicular fluid was then measured again on day of oocyte pick-up. Pearson correlation and binary regression tests were used for statistical analysis. For Type 1 error, p=5% was selected as cut-off value for statistical significance. RESULTS: Serum AMH level was positively correlated with total number of oocytes retrieved and rate of fertilization and CP (r=0.397, p=0.008; r=0.401, p=0.007; and r=0.382, p=0.011, respectively). There was significantly negative correlation between serum level of follicle-stimulating hormone (FSH) and fertilization rate (r=-0.320; p=0.034), as well as serum FSH level and CP rate (r=-0.308; p=0.042). There were no significant correlations between AMH level in follicular fluid and IVF treatment outcomes. CONCLUSION: Serum AMH levels may be more reliable for prediction of total number of oocytes retrieved and rate of fertilization and CP than AMH levels in follicular fluid. PMID:28058394

    Forsum, Elisabet; Löf, Marie

    2007-01-01

    This review summarizes information regarding how human energy metabolism is affected by pregnancy, and current estimates of energy requirements during pregnancy are presented. Such estimates can be calculated using either increases in basal metabolic rate (BMR) or increases in total energy expenditure (TEE). The two modes of calculation give similar results for a complete pregnancy but different distributions of energy requirements in the three trimesters. Recent information is presented regarding the effect of pregnancy on BMR, TEE, diet-induced thermogenesis, and physical activity. The validity of energy intake (EI) data recently assessed in well-nourished pregnant women was evaluated using information regarding energy metabolism during pregnancy. The results show that underreporting of EI is common during pregnancy and indicate that additional longitudinal studies, taking the total energy budget during pregnancy into account, are needed to satisfactorily define energy requirements during the three trimesters of gestation.

    The first PIVET algorithm for individualized recombinant follicle stimulating hormone (rFSH) dosing in in vitro fertilization, reported in 2012, was based on age and antral follicle count grading with adjustments for anti-Müllerian hormone level, body mass index, day-2 FSH, and smoking history. In 2007, it was enabled by the introduction of a metered rFSH pen allowing small dosage increments of ~8.3 IU per click. In 2011, a second rFSH pen was introduced allowing more precise dosages of 12.5 IU per click, and both pens with their individual algorithms have been applied continuously at our clinic. The objective of this observational study was to validate the PIVET algorithms pertaining to the two rFSH pens with the aim of collecting ≤15 oocytes and minimizing the risk of ovarian hyperstimulation syndrome. The data set included 2,822 in vitro fertilization stimulations over a 6-year period until April 2014 applying either of the two individualized dosing algorithms and corresponding pens. The main outcome measures were mean oocytes retrieved and resultant embryos designated for transfer or cryopreservation permitted calculation of oocyte and embryo utilization rates. Ensuing pregnancies were tracked until live births, and live birth productivity rates embracing fresh and frozen transfers were calculated. Overall, the results showed that mean oocyte numbers were 10.0 for all women <40 years with 24% requiring rFSH dosages <150 IU. Applying both specific algorithms in our clinic meant that the starting dose was not altered for 79.1% of patients and for 30.1% of those receiving the very lowest rFSH dosages (≤75 IU). Only 0.3% patients were diagnosed with severe ovarian hyperstimulation syndrome, all deemed avoidable due to definable breaches from the protocols. The live birth productivity rates exceeded 50% for women <35 years and was 33.2% for the group aged 35-39 years. Routine use of both algorithms led to only 11.6% of women generating >15 oocytes

    Objective Investigate the effect of transient hyperglycemic intake (analogous to snacking on high glycaemic foods) in the third trimester of pregnancy on offspring birthweight and subsequent growth in sheep. Design Randomised trial. Setting University research farm. Sample Third trimester pregnant ewes. Methods Ewes were blocked on weight, age and litter size and were randomly assigned to receive oral administration of 100 ml of propylene glycol (PG; n = 51) or 100 ml of water (control, C; n = 53) twice/day. Twice during treatment, 12 ewes from each group were selected and blood samples collected to determine the glucose and insulin response to treatment. Main outcome measures At birth, blood was collected from the lambs, their body dimensions measured and body weights recorded at 0, 6 and 12 weeks of age after which lambs were slaughtered when they reached 40 kg live weight. Results Administration of PG elevated (P < 0.05) plasma glucose and insulin concentrations for 2 hours post administration compared with control ewes. Lambs (C: n = 80; PG: n = 70) born to ewes fed high glycaemic meals had higher birthweights (C: 5.01 ± 0.18 kg; PG: 5.27 ± 0.22 kg, P = 0.032), plasma glucose concentrations (P = 0.001) and ponderal index (weight/height3, P = 0.043) and reached a similar (P > 0.05) slaughter carcass weight (C: 20.0 ± 0.51 kg; PG: 20.6 ± 0.55 kg) at an earlier age (PG: 166.0 ± 13.2; C: 183.4 ± 13.8 days, P = 0.039) compared with control lambs. Conclusions Transient high glycaemic intakes in the third trimester of pregnancy resulted in heavier offspring at birth that had faster growth rates in early postnatal life. This animal model is relevant for studying the relationship between maternal diet, fetal size and the risk of childhood obesity. PMID:19385960

Although most pregnant women do not meet minimal exercise recommendations, there are a growing number of physically active women who wish to continue training throughout pregnancy. Evidence Acquisition: A search of the Web of Science database of articles and reviews available in English through 2014. The search terms exercise pregnancy, strenuous exercise pregnancy, and vigorous exercise pregnancy were used. Study Design: Clinical review. Level of Evidence: Level 3. Results: With proper attention to risk stratification and surveillance, exercise is safe for the mother and fetus. Benefits of exercise in pregnancy include reduction in Cesarean section rates, appropriate maternal and fetal weight gain, and managing gestational diabetes. Exercise as a means of preventing gestational diabetes, preeclampsia, or perinatal depression cannot be reliably supported. Overall, the current evidence suffers from a lack of rigorous study design and compliance with physical activity interventions. Conclusion: Research thus far has been unable to consistently demonstrate proposed benefits of exercise in pregnancy, such as preventing gestational diabetes, preeclampsia, or perinatal depression. However, moderate- and high-intensity exercise in normal pregnancies is safe for the developing fetus and clearly has several important benefits. Thus, exercise should be encouraged according to the woman’s preconception physical activity level. PMID:26502446

  2. [Denial of pregnancy].

    With an incidence of 1:500, denial of pregnancy is a rather frequent incident in obstetrics. Strikingly, in our society, this issue is placed under a taboo. Reasons might be our moral values and socialization. Since pregnancy and motherhood have to be associated with joy, other sensations are often perceived as socially not accepted and thus denied. A similar phenomenon exists e. g. with postnatal depression.In all existing studies on denial of pregnancy, it was proven that there are no significant at-risk groups. Instead, it occurs in all social and educated classes and no association with parity was shown.Psychologically, the denial can be understood as an adaptive or anxiety disorder. Unconsciously, it serves as a defense mechanism against intrapsychic conflicts. Reinterpretation of physical changes allow sustained unconscious and thus conflict even in the presence of fetal movements and while body weight and abdominal girth are increasing.Lacking and insufficient preventive examinations increase risks for mother and child. Especially, when delivery takes place without professional help.The earlier the pregnant woman realizes her condition, if necessary with help from a reference person or medical personnel, the lower the risks. This implies to train detection and overcome fear of addressing the woman. After the pregnancy is revealed, the woman needs to be integrated into a social network, which conveys that denial of pregnancy is not a psychotic symptom and occurs more often than assumed. If this succeeds, the perspective for mother and child is favorable.

  3. Which issues concerning multiple pregnancies should be addressed during psychosocial counselling?

    PubMed

    Emery, Marysa

    2007-01-01

    The global rise in multiple pregnancy rates due to assisted reproductive technology has led to the development of various strategies to diminish these rates without jeopardising pregnancy. Policies at treatment centres may include the option of fetal reduction, although each centre is subject to national laws and its own guidelines. However, personal opinions and goals may also influence practice. The development of clinical decisions, therefore, is complex and subject to change. Primary prevention is the best way to reduce multiple births. For preventative psychosocial counselling, some centres employ counsellors, but if not, this becomes the physician's task. An in-depth assessment is required to define how many embryos to transfer and what risk of multiple birth is acceptable to patients. Counselling should address the following: the relationship between pregnancy rate, multiple pregnancy rate and the number of embryos transferred; benefits and risks of multiple pregnancy; and possibilities for primary and secondary prevention. Patients should voice how they feel facing these issues; which issues are worrisome; how they anticipate these possibilities; and what psychosocial support exists that could be mobilized. In summary, psychosocial counselling reinforces the partnership between couples and the assisted reproductive technology team, allowing for primary prevention and informed consent on multiple pregnancy issues.

  4. Rates and predictors of postpartum depression by race and ethnicity: results from the 2004 to 2007 New York City PRAMS survey (Pregnancy Risk Assessment Monitoring System).

    The objective of this study was to examine racial/ethnic disparities in the diagnosis of postpartum depression (PPD) by: (1) identifying predictors that account for prevalence rate differences across groups, and (2) comparing the strength of predictors across groups. 3,732 White, African American, Hispanic, and Asian/Pacific Islander women from the New York City area completed the Pregnancy Risk Assessment Monitoring System from 2004 to 2007, a population-based survey that assessed sociodemographic risk factors, maternal stressors, psycho-education provided regarding depression, and prenatal and postpartum depression diagnoses. Sociodemographic and maternal stressors accounted for increased rates in PPD among Blacks and Hispanics compared to Whites, whereas Asian/Pacific Islander women were still 3.2 times more likely to receive a diagnosis after controlling for these variables. Asian/Pacific Islanders were more likely to receive a diagnosis after their providers talked to them about depressed mood, but were less likely than other groups to have had this conversation. Prenatal depression diagnoses increased the likelihood for PPD diagnoses for women across groups. Gestational diabetes decreased the likelihood for a PPD diagnosis for African Americans; a trend was observed in the association between having given birth to a female infant and increased rates of PPD diagnosis for Asian/Pacific Islanders and Whites. The risk factors that account for prevalence rate differences in postpartum diagnoses depend on the race/ethnic groups being compared. Prenatal depression is confirmed to be a major predictor for postpartum depression diagnosis for all groups studied; however, the associations between other postpartum depression risk factors and diagnosis vary by race/ethnic group.

  5. Pregnancy associated breast cancer and pregnancy after breast cancer treatment.

    Breast cancer is one of the most common cancers diagnosed during pregnancy and its frequency is increasing as more women postpone their pregnancies to their thirties and forties. Breast cancer diagnosis during pregnancy and lactation is difficult and complex both for the patient and doctors. Delay in diagnosis is frequent and treatment modalities are difficult to accept for the pregnant women. The common treatment approach is surgery after diagnosis, chemotherapy after the first trimester and radiotherapy after delivery. Even though early stage breast cancers have similar prognosis, advanced stage breast cancers diagnosed during pregnancy and lactation have poorer prognosis than similar stage breast cancers diagnosed in non-pregnant women. Women who desire to become pregnant after treatment of breast cancer will have many conflicts. Although the most common concern is recurrence of breast cancer due to pregnancy, the studies conducted showed that pregnancy has no negative effect on breast cancer prognosis. In this review we search for the frequency of breast cancer during pregnancy, the histopathological findings, risk factor, diagnostic and treatment modalities. We reviewed the literature for evidence based findings to help consult the patients on the outcome of breast cancer diagnosed during pregnancy and lactation, and also inform the patients who desire to become pregnant after breast cancer according to current evidences.

    Objective The aims of the present study were to investigate the women's perspective on influenza infection and vaccination and to evaluate how they influence vaccine acceptability, in Korean women of childbearing age. Methods This was a prospective study by random survey of women of childbearing age (20 to 45 years). They were asked to complete a questionnaire assessing their knowledge, attitudes and acceptability of influenza vaccination before and during pregnancy. This study utilized data from the Korea National Health and Nutrition Examination Survey (KNHANES) between 2008 and 2012, to analyze the recent influenza vaccination trends. Results According to KNHANES (2008-2012), influenza vaccination rates in women of childbearing age have increased up to 26.4%, after 2009. The questionnaire was completed by 308 women. Vaccination rate during pregnancy or planning a pregnancy was 38.6%. The immunization rate increased significantly with the mean number of correct answers (P<0.001). Women who received influenza vaccination were more likely to be previously informed of the recommendations concerning the influenza vaccination before or during pregnancy, received the influenza vaccination in the past, and of the opinion that influenza vaccination is not dangerous during pregnancy, with odds ratios of 14.6 (95% confidence interval [CI], 6.44 to 33.33; P<0.0001), 3.6 (95% CI, 1.84 to 6.97; P=0.0002) and 2.7 (95% CI, 1.34 to 5.47; P=0.0057). Conclusion Influenza vaccination rate in women of childbearing age has increased in this study and national data. More information and recommendation by healthcare workers, especially obstetricians, including safety of vaccination, might be critical for improving vaccination rate in women of childbearing age.

    Aim: The aim of this study was to review our experience with gestations in autoimmune hepatitis patients. Background: There are only limited data describing pregnancy in patients with autoimmune hepatitis. Patients and methods: Retrospective analysis of pregnancies with autoimmune hepatitis followed in Centro Hospitalar do Porto, Portugal in the last ten years. Results: We reported nine pregnancies in seven patients with autoimmune hepatitis. Two patients had documented liver cirrhosis prior to the pregnancy. In this study, 66.7% of patients were treated with azathioprine and 88.9% with prednisolone. Clinical improvements were observed in 11.1% of pregnancies and 22.2% exacerbations were diagnosed. There were six live births and two preterm deliveries (preterm delivery rate of 33%). We also report three first trimester miscarriages (early gestation miscarriage rate of 33%). There were no neonatal or maternal deaths. Conclusion: The favorable obstetric outcome is a realistic expectation in patients with autoimmune hepatitis. Tight monitoring and control of asymptomatic and unpredictable exacerbations, which are unrelated to the severity of the underlying disease, are essential to the prognosis of the current pregnancy.

    A retrospective analysis evaluated pregnancy rates and embryo losses with in vitro-produced embryos in a commercial embryo transfer program on 15 different beef farms. Recipients were beef cows and heifers (n=1841) that were synchronized with 5 different protocols and transferred at a fixed-time (FTET). Recipients were examined by ultrasonography on Day 0, and those with a corpus luteum (CL) or a follicle ≥8mm in diameter and with body condition score 2 to 4 (1 to 5 scale) were synchronized. The synchronization treatments were as follows. (T1) Recipients received an intravaginal device with 0.5g of progesterone plus 2mg of oestradiol benzoate on Day 0; device removal, plus 500μg of cloprostenol (prostaglandin F2α), 400IU of eCG, and 0.5mg of oestradiol cypionate on Day 8; and FTET on Day 17. (T2) This treatment was similar to T1 but 1mg of oestradiol cypionate was injected at device removal instead of 0.5mg of oestradiol cypionate. (T3) This treatment was similar to T1 except that animals were tail-painted on Day 8 and observed on Day 10. Those with the tail-paint intact on Day 10 received 100μg of gonadorelin (gonadotropin-releasing hormone) and all recipients were FTET on Day 17. (T4) Recipients received a progesterone device on Day 0; device removal, prostaglandin F2α, and eCG on Day 5; gonadotropin-releasing hormone on Day 8; and FTET on Day 15. (T5) Recipients received a progesterone device and 2mg of oestradiol benzoate on Day 0; device removal, prostaglandin F2α, and eCG on Day 6; gonadotropin-releasing hormone on Day 9; and FTET on Day 16. On the day of FTET all recipients with CL ≥18mm in diameter (G1), ≥16 and <18mm in diameter (G2), and ≥14mm and <16mm in diameter (G3) received in vitro-produced fresh embryos. Pregnancy was diagnosed by ultrasonography at 30 and 60 days of gestation, and data were analysed by logistic regression. The overall proportion of recipients synchronized that were FTET was 80.8% (1487/1841), with a 30-day pregnancy

    Kent, N E; Farquharson, D F

    1993-01-01

    OBJECTIVE: To review the outcomes of pregnancies in women with cystic fibrosis (CF) and to address issues pertinent to the obstetric care of such women. DATA SOURCES: English-language case reports and case series published from 1960 to 1991 identified through a search of MEDLINE and Index Medicus. The terms of reference were "cystic fibrosis" and "pregnancy". Not all the reports reviewed addressed all the outcomes under consideration. STUDY SELECTION: A total of 20 reports citing cases of pregnancy in women with CF. DATA EXTRACTION: Outcomes included the number of spontaneous abortions, pregnancies continued beyond 20 weeks, preterm deliveries, maternal deaths at 6 months and 2 years after delivery and perinatal deaths. Breast-feeding was addressed. Measures to assess the severity of maternal disease included the mean age at diagnosis of CF, weight gain during pregnancy, pulmonary function studies if available and the need for pancreatic enzyme replacement therapy. DATA SYNTHESIS: Of 217 pregnancies in 162 women spontaneous abortion occurred in 10 (4.6%). Pregnancy progressed beyond 20 weeks in 81.6% of cases; 24.3% of the deliveries were preterm. The maternal death rate did not exceed that among age-related women with CF who were not pregnant. The rate of perinatal death was 7.9%. Breast milk was not hypernatremic. Poor outcomes were associated with a weight gain of less than 4.5 kg and a forced vital capacity of less than 50% of the predicted value. CONCLUSIONS: Premature labour and delivery remain a significant risk for pregnant women with CF, contributing to a high rate of perinatal death. Maternal illness and death result from deteriorating pulmonary function. Breast-feeding is not contraindicated. Attention to energy intake and pulmonary function is important. PMID:8374843

  13. Thrombophilia and Pregnancy Complications.

    2015-11-30

    There is a paucity of strong evidence associated with adverse pregnancy outcomes and thrombophilia in pregnancy. These problems include both early (recurrent miscarriage) and late placental vascular-mediated problems (fetal loss, pre-eclampsia, placental abruption and intra-uterine growth restriction). Due to poor quality case-control and cohort study designs, there is often an increase in the relative risk of these complications associated with thrombophilia, particularly recurrent early pregnancy loss, late fetal loss and pre-eclampsia, but the absolute risk remains very small. It appears that low-molecular weight heparin has other benefits on the placental vascular system besides its anticoagulant properties. Its use is in the context of antiphospholipid syndrome and recurrent pregnancy loss and also in women with implantation failure to improve live birth rates. There is currently no role for low-molecular weight heparin to prevent late placental-mediated complications in patients with inherited thrombophilia and this may be due to small patient numbers in the studies involved in summarising the evidence. There is potential for low-molecular weight heparin to improve pregnancy outcomes in women with prior severe vascular complications of pregnancy such as early-onset intra-uterine growth restriction and pre-eclampsia but further high quality randomised controlled trials are required to answer this question.

  14. Mammary cancers and pregnancy.

    PubMed Central

    Anderson, J M

    1979-01-01

    Uncertainties persist about management and prognosis of mammary cancers that occur during and after pregnancy and during lactation. Pathological features of mammary cancers occurring during pregnancy are the same as those in non-pregnant women and survival rates are comparable. Management should be the same as in non-pregnant patients. Termination of pregnancy does not improve survival but it should be advised if the prognosis is poor. Mastectomy apparently presents little danger to the fetus, though treatment such as chemotherapy and irradiation should be avoided. Women who have received treatment for mammary cancer need not be advised against subsequent pregnancy. Routine ovarian radiation in non-pregnant premenopausal women is not generally to be recommended, since it does not prolong survival and would deprive some of the chance of further pregnancy. In lactating women who develop mammary cancers survival is apparently not adversely affected. Lactation should be suppressed initially and followed by mastectomy. Regimens of immunotherapy, chemotherapy, or radiotherapy may then be begun. Until results of current trials of combined treatments of mammary cancers associated with pregnancy are available, management should be neither aggressive nor tentative. It should be based on a well-balanced concept of applying all available treatments, as in non-pregnant patients. PMID:376044

  15. Pregnancy and kidney transplantation.

    PubMed

    Josephson, Michelle A; McKay, Dianne B

    2011-01-01

    Despite decades of experience with child bearing in women with kidney transplants, these pregnancies remain high risk with an increased prevalence of hypertension and pre-eclampsia. Infertility, common in women with end-stage renal disease, is rapidly restored after transplant although pregnancy rates appear lower in transplant recipients than the general public. Many unanswered questions exist, some old questions such as what is the optimal timing of pregnancy after transplant, whether breast feeding is safe, the long-term impact if any on the offspring, and whether pregnancy negatively affects the kidney graft; and some new questions such as whether to modify immunosuppression in a patient taking a mycophenolic acid-containing drug, whether kidney donation has a deleterious impact on future pregnancies, whether to use erythropoietin-stimulating agents, and the role of BK virus. Counseling about contraception and pregnancy after transplant should be initiated during the pretransplant evaluation process. It is important because of the rapid restoration of fertility that occurs after transplant as well as the many risks and unanswered questions that remain.

    Fortification can help individuals achieve adequate nutritional intake. Foods may be fortified with soy flour as a source of protein for individuals limiting their intake of animal products, either due to personal dietary preference or to reduce their intake of saturated fat, a known risk factor for heart disease. This study determined the feasibility of fortifying peanut butter graham crackers by substituting soy flour for all-purpose wheat flour at 25%, 50%, 75%, or 100% weight/weight. Graham crackers fortified with soy flour were compared to similarly prepared nonfortified peanut butter graham crackers. Moisture contents of all graham crackers were similar. Consumers (n=102) evaluated each graham cracker using a hedonic scale and reported liking the color, smell, and texture of all products. However, unlike peanut butter graham crackers fortified with lower levels of soy, graham crackers fortified with 100% weight/weight soy flour had less than desirable flavor, aftertaste, and overall acceptability. Overall, this study shows that fortification of peanut butter graham crackers up to 75% weight/weight with soy flour for all-purpose wheat flour is acceptable.

    Black teenage pregnancy and sexually transmitted diseases in South Africa have reached a threatening level. Accepting that teenage pregnancy is multi-causational, this article outlines selected consequences. It concludes that teenage pregnancy as a social problem needs reexamination in terms of two hypotheses: that the pheronomal climate has an impact on prepuberal girls; and that teenage pregnancy is nature's way of ensuring the survival of the species.

  19. Pregnancy and scleroderma.

    PubMed

    Silman, A J

    1992-01-01

    Scleroderma is a rare disease with a marked female excess in incidence. The pattern of age of onset, together with the effects of the disease, are such that the majority of women with scleroderma experience pregnancy prior to diagnosis. There are three questions of interest: (1) Does pregnancy adversely affect the prognosis of scleroderma? Isolated case reports suggest that renal disease, and in particular hypertensive crises, are associated with pregnancy in the absence of any renal abnormality before pregnancy. However, such events are rare. (2) Does scleroderma adversely affect either fertility or the outcome of pregnancy? Women with established scleroderma, again in case series, have a high rate of spontaneous miscarriage which is not found consistently in epidemiological studies. Prematurity and low birth rates are more frequent problems. (3) Does reproductive history influence disease and particularly Raynaud's phenomenon may antedate diagnosis by many years and might influence reproductive outcome, in general reproductive outcome is similar to that seen after diagnosis, although fertility appears to be reduced.

    Adolescent pregnancy, although on the decline, represents a significant public health concern. Often adolescents present late to prenatal care, either from lack of knowledge, fear of consequences, limited access, stigma, or all of the above. Although multifaceted, there are many risks both to mother and child that are increased in adolescent pregnancy. Many are unintended and are at risk for repeat adolescent pregnancy, especially within the first 2 years. Risks include but are not limited to: low birth weight, preterm delivery, stillbirth, and preeclampsia, as well as feelings of social isolation, delayed or neglected educational goals, and maternal depression.

    In a retrospective cohort study undertaken in 12 European countries, 249 female narcoleptic patients with cataplexy (n = 216) and without cataplexy (n = 33) completed a self-administrated questionnaire regarding pregnancy and childbirth. The cohort was divided further into patients whose symptoms of narcolepsy started before or during pregnancy (308 pregnancies) and those in whom the first symptoms of narcolepsy appeared after delivery (106 pregnancies). Patients with narcolepsy during pregnancy were older during their first pregnancy (P < 0.001) and had a higher body mass index (BMI) prior to pregnancy (P < 0.01). Weight gain during pregnancy was higher in narcoleptic patients with cataplexy (P < 0.01). More patients with narcolepsy-cataplexy during pregnancy had impaired glucose metabolism and anaemia. Three patients experienced cataplexy during delivery. The rate of caesarean sections was higher in the narcolepsy-cataplexy group compared to the narcolepsy group (P < 0.05). The mean birth weight and gestational age of neonates were within the normal range and did not differ across groups. Neonatal care was affected adversely by symptoms of narcolepsy in 60.1% of those with narcolepsy during pregnancy. This study reports more obstetric complications in patients with narcolepsy-cataplexy during pregnancy; however, these were not severe. This group also had a higher BMI and higher incidence of impaired glucose metabolism during pregnancy. Caesarian section was conducted more frequently in narcolepsy-cataplexy patients, despite cataplexy being a rare event during delivery. Furthermore, symptoms of narcolepsy may render care of the infant more difficult.

  3. Pregnancy-associated plasma protein A (PAPP-A) and preeclampsia.

    PubMed

    Kalousová, Marta; Muravská, Alexandra; Zima, Tomás

    2014-01-01

    Pregnancy-associated plasma protein A (PAPP-A) is a key regulator of insulin-like growth factor bioavailability essential for normal fetal development. In maternal blood, this protein increases with gestational age and then rapidly decreases after delivery. It is routinely used for Down syndrome screening in the first trimester of pregnancy, and its decrease compared to a normal pregnancy indicates an increased risk for both chromosomal anomalies and adverse pregnancy outcomes. It belongs to a group of biomarkers that predict later preeclampsia development, primarily early onset preeclampsia; however, it should be combined with a Doppler ultrasonography of the uterine artery (pulsatile index) and other biochemical and maternal factors to achieve a higher detection rate with an acceptable false positivity rate. Some studies have demonstrated an even more pronounced decrease of PAPP-A in the early second trimester of pregnancy in women who subsequently develop preeclampsia compared with women who do not develop preeclampsia. Conversely, during the last trimester of pregnancy, its concentration increases even more in patients with preeclampsia than in patients without. It is also detectable at very low levels in nonpregnant individuals, and a higher concentration indicates an adverse effect in patients with acute coronary syndromes or stable atherosclerotic disease and in patients with end-stage renal disease who are being treated with hemodialysis.

    The overall objective was to compare the efficacy of GnRH, porcine LH (pLH) and estradiol cypionate (ECP), in a modified Ovsynch/fixed-time AI (FTAI) protocol that included a controlled internal drug [progesterone] release (CIDR) device. In Experiment 1, heifers received a CIDR on Day -10, and PGF (25mg) on Day -3. At CIDR insertion, heifers received 100 microg of GnRH (n=6), 0.5mg of ECP (n=6), 5.0mg of pLH (n=6) or 2 mL of saline (n=7); these treatments were repeated on Day -1, except for ECP, that was repeated on Day -2, concurrent with CIDR-removal. The 5.0 mg pLH was the least effective with a longer interval to ovulation than the other groups combined (102 versus 64 h; P<0.05). Overall mean LH concentrations (1.6 ng/mL) and area under the curve (AUC) did not differ among treatments, but mean peak LH concentration was lower in heifers given 5 mg of pLH compared to all other groups (4.5 versus 10.3 ng/mL; P<0.05). In Experiment 2, heifers on CIDR-based Ovsynch protocols were given 12.5mg pLH (n=6; pLH-low), 25.0 mg pLH (n=6, pLH-high), or 100 microg GnRH (n=5; control). Heifers in the pLH-high group had greater (P<0.01) plasma LH concentrations (between 12 and 20 h) than GnRH-treated heifers, but the pLH treatments did not differ (P>0.10). Area under the curve for LH (ng/32 h) was at least 50% greater (P<0.01) in pLH-treated heifers compared to GnRH-treated heifers (mean, 41.3, 56.3 and 20.3 for pLH-low, pLH-high and GnRH, respectively). Ovulation occurred in 15 of 17 heifers. Progesterone concentrations were higher on Days 9 and 14 in heifers given 25mg of pLH, suggesting enhanced CL function. In Experiment 3, 240 heifers were assigned to CIDR-based Ovsynch/FTAI protocols. The first and second hormonal treatments (with an intervening PGF treatment on Day -3) were GnRH/GnRH (100 microg), ECP/ECP (0.5 mg), pLH/pLH (12.5 mg) or GnRH/ECP, respectively; pregnancy rates were 58.7, 66.1, 45.9 and 48.3%, respectively (ECP/ECP>both pLH/pLH and GnRH/ECP; P

The trial was performed on 56 pluriparous buffaloes at 86.8 ± 8.1 d in milk. The animals underwent individual louse count and were divided into 2 homogenous groups according to louse count, age, number of lactations, days in milk, live BW, BCS, pregnancy status, and milk yield. Group A (n = 28) was treated by a pour-on formulation of ACYP, and Group S (n = 28) was treated by pour-on saline solution. Individual louse counts were performed weekly on 10 buffaloes in each group. Feed intake was recorded daily and the total mixed ration, individual ingredients, and orts were analyzed to calculate DM ingestion. Individual milk yield was recorded daily and milk samples were analyzed at the beginning of the trial, after 4 wk, and at the end of the trial to assess milk composition. Individual BCS was also evaluated simultaneously. Finally, the animals underwent synchronization of ovulation starting 4 wk after treatment and the pregnancy rate and the calving-conception interval were evaluated. Data were analyzed by the Mann-Whitney test and ANOVA for repeated measures. The infestation was constant in Group S, whereas no lice were present in Group A throughout the study. Daily DMI was similar in the 2 groups (16.7 ± 0.4 vs. 16.3 ± 0.3 kg/d in Group A vs. Group S, respectively), although buffaloes in Group A showed higher (P < 0.05) BCS score at the end of the trial (7.39 ± 0.1 vs. 7.14 ± 0.1 in Group A vs. Group S, respectively). The average milk yield/buffalo was higher (P < 0.05) in Group A compared to Group S (10.58 ± 0.1 vs. 10.39 ± 0.1 kg in Group A vs. Group S, respectively) and this was mainly due to the higher milk production recorded in buffaloes at less than 75 d in milk (11.81 ± 0

    Introduction. Rennin-angiotensin system and salt diet play important roles in blood pressure control. We hypothesized that the high-salt intake during pregnancy influences the degree of angiotensin-dependent control of the blood pressure in adult offspring. Methods. Female Wistar rats in two groups (A and B) were subjected to drink tap and salt water, respectively, during pregnancy. The offspring were divided into four groups as male and female offspring from group A (groups 1 and 2) and from group B (groups 3 and 4). In anesthetized matured offspring mean arterial pressure (MAP), heart rate and urine output were measured in response to angiotensin II (AngII) (0-1000 ng/kg/min, iv) infusion. Results. An increase in MAP was detected in mothers with salt drinking water (P < 0.05). The body weight increased and kidney weight decreased significantly in male offspring from group 3 in comparison to group 1 (P < 0.05). MAP and urine volume in response to AngII infusion increased in group 3 (P < 0.05). These findings were not observed in female rats. Conclusion. Salt overloading during pregnancy had long-term effects on kidney weight and increased sex-dependent response to AngII infusion in offspring (adult) that may reveal the important role of diet during pregnancy in AngII receptors.

    The interval from both spontaneous and prostaglandin (PGF)-induced luteolysis to ovulation is greatly variable in mares. Several reports have shown a positive association between the length of the interval from PGF treatment to ovulation (ITO) and the subsequent pregnancy rate (PR). However, it is not known whether this association also occurs in estrous cycles with spontaneous luteolysis. The main objective of this study was to determine the effect of the duration of estrus-like echotexture of the uterus during the follicular phase on the subsequent PR in both spontaneous and PGF-induced cycles. A total of 768 estrous cycles from 325 thoroughbred mares were analyzed (401 estruses were induced with exogenous PGF and 367 cycles were not treated with PGF). The following factors were taken into account to determine the effect on PR: age of the mare, stallion, year of breeding, month of season, reproductive status of the mare, use of PGF treatment, duration of follicular phase with estrus-like echotexture, interovulatory interval (IOI; in spontaneous cycles), and ITO (in PGF-induced cycles). The age of the mare (P = 0.017), mare status (P = 0.031), the ITO (P = 0.041), and the duration of the follicular phase with estrus-like echotexture (P < 0.001) influenced the PR. The PR increased with the duration of estrus and of endometrial edema in both PGF-induced and spontaneous cycles. The correlation between the duration of endometrial edema and the IOI and ITO was positive (r = 0.5) and significant (P < 0.05).

    Aim. To determine pregnancy and delivery outcomes among teenagers. Materials and Methods. An 8-year retrospective comparative hospital-based cohort study is analysing singleton pregnancy comorbidities and delivery parameters of a teenage group under the age of 20 compared with a young adult group 20-24 years of age in a university hospital. Results. Teenage is a risk factor for preterm birth <37 weeks (1.21 [1.08-1.35]), foetal growth restriction (1.34 [1.21-1.48]), episiotomy (1.27 [1.21-1.34]), uterine revision (1.15 [1.06-1.25]), APGAR <7 at 1 min (2.42 [1.21-1.67]), cephalopelvic disproportion (1.26 [1.07-1.48]), and postpartum haemorrhage (1.42 [1.25-1.62]); however, caesarean delivery occurs less frequently in teenagers than in adults (0.75 [0.70-0.80]). The following comorbidities are risk factors for teenage pregnancy (risk ratio [CI 95%]): anaemia (1.13 [1.10-1.17]), low urinary tract infection (1.10 [1.03-1.18]), pediculosis (2.42 [1.90-3.00]), anogenital condyloma (1.50 [1.04-2.17]), and trichomoniasis (1.74 [1.12-2.68]). The risks for hepatitis B and hepatitis C, premature rupture of membranes, and placenta praevia were lower compared with those in the young adult group, respectively, 0.43 (0.26-0.71), 0.90 (0.85-0.96), and 0.29 (0.20-0.41), while the risk for gestational diabetes and preeclampsia were the same in both groups. Conclusion. Considering the high risks for teenage pregnancy, this information should be provided to pregnant adolescent women and their caregivers.

    Intrahepatic cholestasis of pregnancy (ICP) is a pregnancy-specific liver disorder characterized by maternal pruritus in the third trimester, raised serum bile acids and increased rates of adverse fetal outcomes. The etiology of ICP is complex and not fully understood, but it is likely to result from the cholestatic effects of reproductive hormones and their metabolites in genetically susceptible women. Equally unclear are the mechanisms by which the fetal complications occur. This article reviews the epidemiology, clinical features, diagnosis, etiology and management of ICP. PMID:19418576

    This study compared pregnancy rates (PRs) and costs per calf born after fixed-time artificial insemination (FTAI) or AI after estrus detection (i.e., estrus detection and AI, EDAI), before and after a single PGF2α treatment in Bos indicus (Brahman-cross) heifers. On Day 0, the body weight, body condition score, and presence of a CL (46% of heifers) were determined. The heifers were then alternately allocated to one of two FTAI groups (FTAI-1, n = 139) and (FTAI-2, n = 141) and an EDAI group (n = 273). Heifers in the FTAI groups received an intravaginal progesterone-releasing device (IPRD; 0.78 g of progesterone) and 1 mg of estradiol benzoate intramuscularly (im) on Day 0. Eight days later, the IPRD was removed and heifers received 500 μg of PGF2α and 300 IU of eCG im; 24 hours later, they received 1 mg estradiol benzoate im and were submitted to FTAI 30 to 34 hours later (54 and 58 hours after IPRD removal). Heifers in the FTAI-2 group started treatment 8 days after those in the FTAI-1 group. Heifers in the EDAI group were inseminated approximately 12 hours after the detection of estrus between Days 4 and 9 at which time the heifers that had not been detected in estrus received 500 μg of PGF2α im and EDAI continued until Day 13. Heifers in the FTAI groups had a higher overall PR (proportion pregnant as per the entire group) than the EDAI group (34.6% vs. 23.2%; P = 0.003), however, conception rate (PR of heifers submitted for AI) tended to favor the estrus detection group (34.6% vs. 44.1%; P = 0.059). The cost per AI calf born was estimated to be $267.67 and $291.37 for the FTAI and EDAI groups, respectively. It was concluded that in Brahman heifers typical of those annually mated in northern Australia FTAI compared with EDAI increases the number of heifers pregnant and reduces the cost per calf born.

    An overlap of breast-feeding and late pregnancy is associated with decreased intake of human milk and reduced infant growth. We evaluated the association of an overlap with macronutrient and immunological components of milk, infant urinary IgA, and infant and maternal morbidity. On d 2 and 1 mo postpartum, staff measured 24-h intake of breast milk and collected samples from 133 Peruvian women; 68 had breast-fed during the last trimester of pregnancy (BFP) and 65 had not breast-fed during pregnancy (NBFP). Data on maternal and infant anthropometry and health were collected for 1 mo. On d 2, lactose and lysozyme concentrations were higher, total lysozyme intake was higher and concentration and total intake of lactoferrin were lower in the BFP than the NBFP group (P < 0.05). The total 1-mo IgA intake was lower among BFP than NBFP infants (P = 0.01). Urinary IgA concentration was correlated with breast milk IgA concentration (r = 0.29; P = 0.01) but not with breast-feeding during pregnancy. An overlap was not associated with diarrhea but BFP infants were 5 times as likely to have a cough for at least 7 d than NBFP infants (P < 0.05). Reported mastitis was rare and occurred only in the NBFP group (P = 0.05). An overlap of breast-feeding and late pregnancy was associated with changes in milk composition, an increased frequency in symptoms of infant respiratory illness but decreased reported mastitis. Further in-depth studies are warranted to determine the cumulative effects associated with a breast-feeding/pregnancy overlap on infant and maternal outcomes. PMID:12888642

    The prevalence of chronic kidney disease in women of childbearing age reaches approximately 0.2%. Under physiological conditions pregnancy results in important hemodynamic changes on the maternal organism. In the case of chronic kidney disease these adaptations often are only partial. Physiological changes of immune response during pregnancy may contribute to the progress of renal disease. Regardless of the underlying kidney disease, one can assume that the better the glomerular filtration rate and blood pressure are the more favorable the course of pregnancy will be with the chance for a healthy child and stable renal function. To achieve this goal, a close interaction is required between gynecologist, nephrologist, and other specialists in a center with appropriate experience.

  15. Eisenmenger Syndrome in Pregnancy

    Eisenmenger syndrome is very rare in pregnant women. Debates remain concerning the management of Eisenmenger syndrome in this patient population and the prognosis is unclear in terms of maternal and fetoneonatal outcomes. Epidural analgesia is preferred for Cesarean section as it alleviates perioperative pain and reduces the pulmonary and systemic vascular resistances. Maternal mortality in the presence of Eisenmenger syndrome is reported as 30-50% and even up to 65% in those with Cesarean section. The major causes of death could be hypovolemia, thromboembolism and preeclampsia. Pregnancy should ideally be avoided in a woman with Eisenmenger syndrome concerning the high maternal mortality rate and probable poor prognosis of the baby. A short labour and an atraumatic delivery under epidural block are preferred in the women with a strong desire of pregnancy. The purpose of this article is to discuss the debates of Eisenmenger syndrome in pregnancy and the possible resolutions. PMID:27849306

    The United States must improve its efforts to reduce teen pregnancy. We occupy an alarming position in the developed world from the standpoint of the magnitude of the pregnancy issue. While our society promotes sexuality to sell all sorts of consumer goods, it still refuses for the most part to make contraceptives familiar and available to sexually active teens. The youngest adolescents, 10 to 14 years, are having sex and babies at an increasing rate. Their children will have limited futures. Only by stepping up our efforts to prevent early pregnancy will we make possible a life of opportunity and choice for the young people of our country. Consequences will be costly and tragic if we do not.

    .2%-19.3% vs. 26.4%). The presence of cysteamine during IVM of OPU-derived COCs also significantly increased the embryo production rate (34.4% vs. 23.4%). The higher number of embryos was again totally due to an increased number of blastocysts, whereas cryotolerance was not affected. The relative increase in embryo production rate was higher with OPU-derived oocytes compared with slaughterhouse-derived COCs (47% vs. 24%). This improvement resulted in a mean of 1.73 transferable embryos per OPU session compared with 1.06 in the absence of cysteamine. The presence of cysteamine did not affect pregnancy rate, gestation length, birth weight, perinatal mortality, and sex of calves born from either fresh or frozen-thawed embryos. This study reported that cysteamine supplementation during IVM greatly improved the efficiency and affectivity of an OPU-IVP program.

    Background: Isotretinoin, a teratogen, is widely used to treat cystic acne. Although the risks of pregnancy during isotretinoin therapy are well recognized, there are doubts about the level of adherence with the pregnancy prevention program in Canada. Our objective was to evaluate the effectiveness of the Canadian pregnancy prevention program in 4 provinces: British Columbia, Saskatchewan, Manitoba and Ontario. Methods: Using administrative data, we identified 4 historical cohorts of female users of isotretinoin (aged 12–48 yr) for the period 1996 to 2011. We defined pregnancy using International Statistical Classification of Diseases and billing codes. One definition included only cases with documented pregnancy outcomes (high-specificity definition); the other definition also included individuals recorded as receiving prenatal care (high-sensitivity definition). We studied new courses of isotretinoin and detected pregnancies in 2 time windows: during isotretinoin treatment only and up to 42 weeks after treatment. Live births were followed for 1 year to identify congenital malformations. Results: A total of 59 271 female patients received 102 308 courses of isotretinoin. Between 24.3% and 32.9% of participants received prescriptions for oral contraceptives while they were taking isotretinoin, compared with 28.3% to 35.9% in the 12 months before isotretinoin was started. According to the high-specificity definition of pregnancy, there were 186 pregnancies during isotretinoin treatment (3.1/1000 isotretinoin users), compared with 367 (6.2/1000 users) according to the high-sensitivity definition. By 42 weeks after treatment, there were 1473 pregnancies (24.9/1000 users), according to the high-specificity definition. Of these, 1331 (90.4%) terminated spontaneously or were terminated by medical intervention. Among the 118 live births were 11 (9.3%) cases of congenital malformation. Pregnancy rates during isotretinoin treatment remained constant between 1996 and 2011

  19. Pregnancy testing and counseling.

    PubMed

    Stephenson, J N

    1989-06-01

    Pregnancy testing and counseling are increasingly accepted as necessary services for adolescents within the primary care setting. For teenagers in need of a pregnancy test, the easy-to-perform, highly sensitive and specific enzyme immunoassay analysis for measuring beta-human chorionic gonadotropin (beta-HCG) is ideal. However, no single beta-HCG analysis should be taken as absolute evidence for the presence or absence of pregnancy. Instead, an integrated approach using all of the health care professional's skills in adolescent health care should be taken. In some cases a careful history and physical examination will confirm the pregnancy. At other times serial quantitative serum HCG titers, pelvic ultrasonography, and culdocentesis may be necessary to rule out the possibility of ectopic pregnancy or threatened abortion. For more than three quarters of pregnant adolescents the pregnancy is unplanned and may represent a major conflict for themselves, their partner, and their families. When such an event occurs the health care professional will frequently be sought as a resource. Successful pregnancy counseling has many components. The adolescent will need to visualize the counselor as an available, sensitive, nonjudgmental individual who believes in the right of the pregnant teenager ultimately to progress to her own decision. The counseling process should be firmly based on an understanding of adolescent psychosocial and biologic development, crises intervention techniques, and family dynamics. The counselor needs to be a reliable information source. If the adolescent decides to go to term, programs offering comprehensive prenatal services to teenagers should be identified. Information concerning high-quality, low-cost abortion services also will need to be available for those who wish to terminate. It is important to monitor the quality of care given in prenatal and abortion service referrals. Few adolescents currently choose to place their babies for adoption

    Surgery remains an acceptable, and sometimes necessary, modality for the treatment of ectopic pregnancy. Laparoscopy is the preferred method of access, yet controversy remains regarding the optimal procedure and postoperative management. Generally, salpingostomy is employed with the goal of maintaining fertility, although data to support this tenet are lacking. In most cases, the decision to perform conservative versus radical surgery is on the basis of the patient's history, her desire for future fertility, and surgical findings. The procedures of salpingostomy and salpingectomy, techniques to prevent and control blood loss at the time of surgery, and surgical options for nontubal ectopic pregnancies are reviewed.

    Both youngsters and adults with same-sex attraction are at greater risk for negative health outcomes. Despite mounting efforts to determine the biological background, a satisfactory conclusion has not been reached and there is a need to explore alternate factors like functioning of thyroid system during pregnancy. A retrospective chart review was undertaken of 790 eligible children and adolescents who had been admitted to child psychiatry between 2005 and 2013. This population consisted of 520 (65%) males and 270 (35%) females, aged 8 to 17 years. Fifteen mothers (1.8%) were found to have a history of thyroid dysfunction during pregnancy. Sixteen youngsters (2%) had a history of same-sex attraction. Twelve overlapping cases with both same-sex attraction and maternal thyroid dysfunction during pregnancy were identified, which was extremely significant (P<0.0001, by Fisher’s exact test). The association was also significant for each sex (P<0.0001, by Fisher’s exact test). There is evidence that thyroid gland plays a crucial and decisive role in determining sexual orientation in people. Maternal thyroid dysfunctions during pregnancy may result in homosexual orientation in the offspring. PMID:26605033

  12. Risk management of seasonal influenza during pregnancy: current perspectives

    PubMed Central

    Yudin, Mark H

    2014-01-01

    Influenza poses unique risks to pregnant women, who are particularly susceptible to morbidity and mortality. Historically, pregnant women have been overrepresented among patients with severe illness and complications from influenza, and have been more likely to require hospitalization and intensive care unit admission. An increased risk of adverse outcomes is also present for fetuses/neonates born to women affected by influenza during pregnancy. These risks to mothers and babies have been observed during both nonpandemic and pandemic influenza seasons. During the H1N1 influenza pandemic of 2009–2010, pregnant women were more likely to be hospitalized or admitted to intensive care units, and were at higher risk of death compared to nonpregnant adults. Vaccination remains the most effective intervention to prevent severe illness, and antiviral medications are an important adjunct to ameliorate disease when it occurs. Unfortunately, despite national guidelines recommending universal vaccination for women who are pregnant during influenza season, actual vaccination rates do not achieve desired targets among pregnant women. Pregnant women are also sometimes reluctant to use antiviral medications during pregnancy. Some of the barriers to use of vaccines and medications during pregnancy are a lack of knowledge of recommendations and of safety data. By improving knowledge and understanding of influenza and vaccination recommendations, vaccine acceptance rates among pregnant women can be improved. Currently, the appropriate use of vaccination and antiviral medications is the best line of defense against influenza and its sequelae among pregnant women, and strategies to increase acceptance are crucial. This article will review the importance of influenza in pregnancy, and discuss vaccination and antiviral medications for pregnant women. PMID:25114593

    Teen pregnancy is a social problem not resolved in developing and some developed countries. Adolescent fecundity has become the most exact bio-demographic and health indicator of development. In developing countries that are expected to follow the sexual behaviour patterns of developed countries, without offering the levels of education and services for adolescents, the consequences will be adolescent fecundity and STI prevalence increase. The ignorance about sexuality and reproduction both in parents, teachers and adolescents increases the early initiation of coital relations and of unwanted pregnancies. Extreme poverty and being the son or daughter of an adolescent mother are risk factors of repeating the early pregnancy model. The application of predictive risk criteria in pregnant adolescents to facilitate the rational use of Health Services to diminish the maternal and perinatal mortality is discussed as well as the social factors associated with adolescent pregnancy as socioeconomic levels, structure - types and characteristics of the family, early leaving school, schooling after delivery, female employment, lack of sexual education, parental and family attitudes in different periods of adolescent pregnancy, adolescent decisions on pregnancy and children, unstable partner relationship and adoption as an option. Social consequences are analyzed as: incomplete education, more numerous families, difficulties in maternal role, abandonment by the partner, fewer possibilities of having a stable, qualified and well-paid job, greater difficulty in improving their socioeconomic level and less probability of social advancement, lack of protection of the recognition of the child. Finally, based on evidence, some measures that can reduce adverse consequences on adolescent mothers, fathers and their children are suggested.

  14. Teenage pregnancy: who suffers?

    2009-03-01

    In this review, we examine the epidemiology of teenage pregnancy (girls aged 15-17 years) in the UK and consider the evidence for its impact on the health and well-being of the mother, the baby, the father and society. There has been some decrease in the teenage pregnancy rate over the last decade in the UK but rates are still considerably higher than those in other European countries. Pregnancy and childbirth during the teenage years are associated with increased risk of poorer health and well-being for both the mother and the baby, possibly reflecting the socio-economic factors that precede early pregnancy and childbirth. There is little evidence concerning the impact of teenage fatherhood on health and future studies should investigate this. The effect on society is a perpetuation of the widening gap in health and social inequalities. Public health interventions should aim to identify teenagers who are vulnerable and support those who are pregnant with evidence based interventions such as teenage antenatal clinics and access to initiatives that provide support for early parenthood.

    Transgender people have experienced significant advances in societal acceptance despite experiencing continued stigma and discrimination. While it can still be difficult to access quality health care, and there is a great deal to be done to create affirming health care organizations, there is growing interest around the United States in advancing transgender health. The focus of this commentary is to provide guidance to clinicians caring for transgender men or other gender nonconforming people who are contemplating, carrying, or have completed a pregnancy. Terms transgender and gender nonconforming specifically refer to those whose gender identity (e.g., being a man) differs from their female sex assigned at birth. Many, if not most transgender men retain their female reproductive organs and retain the capacity to have children. Review of their experience demonstrates the need for preconception counseling that includes discussion of stopping testosterone while trying to conceive and during pregnancy, and anticipating increasing experiences of gender dysphoria during and after pregnancy. The clinical aspects of delivery itself fall within the realm of routine obstetrical care, although further research is needed into how mode and environment of delivery may affect gender dysphoria. Postpartum considerations include discussion of options for chest (breast) feeding, and how and when to reinitiate testosterone. A positive perinatal experience begins from the moment transgender men first present for care and depends on comprehensive affirmation of gender diversity. PMID:27030799

    Objective We evaluated the pharmacokinetics (pk) of raltegravir in HIV-infected women during pregnancy and postpartum. Methods IMPAACT 1026s is an on-going prospective study of antiretroviral pk during pregnancy (NCT00042289). Women receiving 400 mg raltegravir twice daily in combination antiretroviral therapy had intensive steady state 12-hour pk profiles performed during pregnancy and at 6–12 weeks postpartum. Targets were trough concentration above 0.035 µg/mL, the estimated tenth percentile in non-pregnant historical controls. Results Median raltegravir AUC was 6.6 µg*hr/mL for second trimester (n= 16), 5.4 µg*hr/mL for third trimester (n=41), and 11.6 µg*hr/mL postpartum (n= 38) (p=0.03 pp vs 2nd trimester, p=0.001 pp vs third trimester). Trough concentrations were above the target in 69%, 80%, and 79% of second trimester, third trimester and postpartum subjects respectively, with wide variability (<0.010–0.917 µg/mL), and no significant difference between third trimester and postpartum trough concentrations was detected. The median ratio of cord blood/maternal raltegravir concentrations was 1.5. HIV RNA levels were < 400 copies/mL in 92% of women at delivery. Adverse events included elevated liver transaminases in one woman and vomiting in one. All infants with known status are HIV-uninfected. Conclusions Median raltegravir AUC was reduced by approximately 50% during pregnancy; trough concentrations were frequently below target both during late pregnancy and postpartum. Raltegravir readily crossed the placenta. High rates of viral suppression at delivery and the lack of a clear relationship between raltegravir concentration and virologic effect in nonpregnant adults suggest that despite the decreased exposure during pregnancy, a higher dose is not necessary.

    Objectives To explore women’s knowledge, attitudes, and beliefs about adverse outcomes associated with smoking during pregnancy and which outcomes might motivate cessation; to explore reactions to graphic warnings depicting 2 adverse outcomes. Methods Twelve focus groups were conducted with women of childbearing age who were current smokers. Results Participants had low to moderate awareness of many outcomes and believed it was acceptable to smoke in the first trimester before knowledge of pregnancy. Perceived susceptibility to outcomes was low. Motivators included risk-focused information, especially serious risks to the baby (eg, stillbirth, SIDS). Graphic warnings produced strong reactions, especially the warning with a real photo. Conclusions Despite barriers to reducing rates of smoking during pregnancy, educational information and photos depicting babies’ risks could motivate women to quit. PMID:24933145

    Despite the fact that the US teenage birth rate has declined dramatically in recent years, teen births among Latinas are higher than any other racial/ethnic group. Most studies focus on the causes and consequences of early motherhood among Latina teenagers, neglecting other important dimensions of the issue. This study examines how Latina/o teenage parents living in California narrate their experiences with unintended pregnancy resolution. Qualitative analysis reveals three central themes. First, participants expressed shock upon learning they or their partner was pregnant, followed by acceptance about their impending parenthood. Second, participants' views of abortion and adoption largely foreclosed these options as pathways by which to resolve their unintended pregnancies. Third, participants recounted numerous stories of the messages they received from parents, other family members and male partners that were frequently directive regarding how to resolve their pregnancies. These findings have implications for young people's reproductive health and rights, and for reproductive justice more broadly.

  20. Diagnosis and management of ectopic pregnancy.

    2014-07-01

    Ectopic pregnancy affects 1% to 2% of all pregnancies and is responsible for 9% of pregnancy-related deaths in the United States. When a pregnant patient presents with first-trimester bleeding or abdominal pain, physicians should consider ectopic pregnancy as a possible cause. The patient history, physical examination, and imaging with transvaginal ultrasonography can usually confirm the diagnosis. When ultrasonography does not clearly identify the pregnancy location, the physician must determine whether the pregnancy is intrauterine (either viable or failing) or ectopic. Use of the beta subunit of human chorionic gonadotropin (ß-hCG) discriminatory level, the ß-hCG value above which an intrauterine pregnancy should be visualized by transvaginal ultrasonography, may be helpful. Failure to visualize an intrauterine pregnancy when ß-hCG is above the discriminatory level suggests ectopic pregnancy. In addition to single measurements of ß-hCG levels, serial levels can be monitored to detect changes. ß-hCG values in approximately 99% of viable intrauterine pregnancies increase by about 50% in 48 hours. The remaining 1% of patients have a slower rate of increase; these patients may have pregnancies that are misdiagnosed as nonviable intrauterine or ectopic. After an ectopic pregnancy has been confirmed, treatment options include medical, surgical, or expectant management. For patients who are medically unstable or experiencing life-threatening hemorrhage, a surgical approach is indicated. For others, management should be based on patient preference after discussion of the risks, benefits, and monitoring requirements of all approaches.

    The acceptability of ultrasound examinations during pregnancy has been documented in many studies. Yet there is little empirical evidence for the postulated psychological benefits of ultrasound examinations. Although seeing the baby is most often rated as a moving experience, there are no proven long-term effects of ultrasound visualization on bonding with the fetus or on pregnant women's health-related maternal behaviour. There is evidence to support the notion that attenuated anxiety and stress immediately following the examination are likely artefactual - a reflection of increased anxiety before real-time scan. Review of the literature indicates no evidence as to whether antenatal detection of fetal abnormalities leads to improvement in coping or only prolongs the phase of psychological stress and mourning. This articles provides an overview of current research on psychological effects of prenatal ultrasound examination.

    Many women report a heightened sense of smell during pregnancy. Accounts of these anecdotes have existed for over 100 years, but scientific evidence has been sparse and inconclusive. In this review, I examine the literature on olfactory perception during pregnancy including measures of self-report, olfactory thresholds, odor identification, intensity and hedonic ratings, and disgust. Support for a general decrease in olfactory thresholds (increase in sensitivity) is generally lacking. There is limited evidence that some suprathreshold measures of olfactory perception, such as hedonic ratings of odors, are affected by pregnancy, but these effects are idiosyncratic. In this review, I explore the hypotheses that have been put forth to explain changes in olfactory perception during pregnancy and provide suggestions for further research. PMID:24567726

    The current meta-analysis aimed to answer the following research question: is progesterone elevation on the day of hCG administration associated with the probability of clinical pregnancy in women undergoing ovarian stimulation for IVF using GnRH antagonists? A literature search in MEDLINE, EMBASE and CENTRAL electronic databases followed by extensive hand-searching from two independent reviewers was performed to identify relevant studies. Eventually five eligible studies (n=585 patients) were identified. No significant differences were present between patients with and those without progesterone elevation regarding female age, duration of stimulation and total dose of gonadotrophins required. However, patients with progesterone elevation were characterized by higher serum estradiol levels on the day of hCG administration (+956 pg/ml, 95% +248 to +1664, random effects model, p=0.008) and more COCs retrieved (+2.9, 95% CI +1.5 to +4.4, fixed effects model, p < 0.001). Progesterone elevation on the day of hCG administration was associated with a significantly decreased probability of clinical pregnancy per cycle (-9%, 95% CI -17 to -2, fixed model effects, p). In conclusion, in patients treated with GnRH antagonists and gonadotrophins, progesterone elevation on the day of hCG administration is significantly associated with a lower probability of clinical pregnancy.

    Preexisting type-I-diabetes (incidence 0.8%) and gestational diabetes (3-5%) are the two manifestations of disturbed carbohydrate metabolism in pregnancy. Maternal hyperglycemia and the resulting excessive glucose supply for the fetus leads to fetal hyperinsulinism which is responsible for the complications in the offspring. The most important clinical manifestations are the excessive growth of the fetus (macrosomia), the risk of intrauterine death and the neonatal morbidity caused by hypoglycemia and the delay of maturation of lungs and liver. Women with type-I-diabetes require preconception counseling and optimizing of glucose control to reduce the rate of abortion and of congenital anomalies of the offspring. Furthermore kidney function and retinopathia should be evaluated preconceptionally. The management of diabetic pregnancies requires a tight cooperation of obstetricians and diabetologists. Blood glucose levels have to be lower than outside pregnancy. Gestational diabetes is diagnosed by a screening test with 50 g glucose for all women followed by a regular 75 g oGTT when the glucose value is > or = 140 mg%. In most of the women euglycemia can be achieved by diet and exercise. Women after pregnancies with gestational diabetes should be retested postnatally and counseled about their increased risk to develop diabetes in later life.

    Pregnancy involves remarkable orchestration of physiologic changes. The kidneys are central players in the evolving hormonal milieu of pregnancy, responding and contributing to the changes in the environment for the pregnant woman and fetus. The functional impact of pregnancy on kidney physiology is widespread, involving practically all aspects of kidney function. The glomerular filtration rate increases 50% with subsequent decrease in serum creatinine, urea, and uric acid values. The threshold for thirst and antidiuretic hormone secretion are depressed, resulting in lower osmolality and serum sodium levels. Blood pressure drops approximately 10 mmHg by the second trimester despite a gain in intravascular volume of 30% to 50%. The drop in systemic vascular resistance is multifactorial, attributed in part to insensitivity to vasoactive hormones, and leads to activation of the renin-aldosterone-angiostensin system. A rise in serum aldosterone results in a net gain of approximately 1000 mg of sodium. A parallel rise in progesterone protects the pregnant woman from hypokalemia. The kidneys increase in length and volume, and physiologic hydronephrosis occurs in up to 80% of women. This review will provide an understanding of these important changes in kidney physiology during pregnancy, which is fundamental in caring for the pregnant patient.

    In Mexico, 20% of the annual births are presented in women younger than 20 years old. Pregnancy in adolescents puts at risk mother and child health. This risk is major while the woman is younger, especially when the social and economic conditions are not favorable, which is decisive in later psychosocial development. It has been pointed out that the youths with low education, with minor academic and laboral expectations, with low self-esteem and assertiveness, tend to begin early their active sexual life, to use less frequently contraceptives, and in the case of younger women, to be pregnant, with the risk of abortion because they cannot to make the best decision. It is important to take into account the social context and the special characteristics of the family to understand situation of adolescent at risk of pregnancy.

    In this study, we explored the effect of acupoint catgut embedding combined with Chinese medicine for nourishing kidney and promoting blood circulation as well as improving the glucose and lipid levels and pregnancy rate in obese polycystic ovary syndrome (PCOS) patients with infertility. A total of 62 obese patients with PCOS were randomly divided into three groups, 21 of whom were treated with acupoint catgut embedding combined with Chinese medicine, another 21 with catgut embedding therapy, and 20 only with Chinese medicine. We compared the improvement of clinical symptoms and the glucose and lipid levels in the three groups three months after surgery. We found that the effective rate of obesity treatment, body mass index and waist-to-hip ratio of acupuncture-drug group and catgut embedding group were significantly lower than those of the Chinese medicine group (P<0.05). A comparison between the acupuncture-drug group and catgut embedding group was not statistically significant (P>0.05). The triglyceride (TG) and high-density lipoprotein cholesterol (HDL) levels of the three groups were significantly decreased and increased, respectively, following treatment, with the total cholesterol (TC) level being decreased significantly only in the acupuncture-drug group (P<0.05), and the LDL level showing no significant difference (P>0.05). The fast insulins, HOMA-IR, TG, TC levels and periodic cancellation rate of the acupuncture-drug group was significantly reduced compared to those of the catgut embedding group and Chinese medicine group after treatment, whereas the HDL levels, periodic ovulation rate and clinical pregnancy rate were higher (P<0.05). However, a comparison between Chinese medicine group and catgut embedding group was not statistically significant (P>0.05). The incidence rate of luteinized unruptured follicle and ovarian hyper-stimulation syndrome of the three groups showed no statistical difference (P>0.05). In conclusion, the study has shown that

    The aim was to evaluate the effect of corn oil supplementation during postpartum anoestrus on ovarian activity, pregnancy rate, progesterone (P(4)), and lipid metabolites (cholesterol, CHO; low and high density lipoproteins; LDL and HDL, respectively) concentrations in blood of F(1) (Bos taurus x Bos indicus) grazing cows. Cows were randomly assigned to an experimental group, fed with a supplement containing 4% corn oil on dry matter basis (OG, n = 11), and a control group with the same supplement without corn oil (CG, n = 12). Both supplements contained equivalent amounts of crude protein and metabolizable energy and were fed for 34 days continuously. All cows were induced to estrous 12 days after beginning of supplementation by using a synthetic progestagen and artificially inseminated 56 h after retiring the implants. Pregnancy diagnosis was performed by transrectal palpation 45 days after insemination, evaluating simultaneously ovarian activity. P(4) and lipid metabolites (CHO, HDL, LDL) concentrations were determined in blood samples collected at 3-day intervals, from the beginning of corn oil supplementation and up to 10 days after artificial insemination. Ovarian activity was affected by treatment (p < 0.05), finding ovarian structures in 72.7% of OG cows and in 50% of CG cows. Concentration of P(4) and CHO was higher for OG with respect to CG (2.52 +/- 0.65 vs 1.88 +/- 0.62 ng/ml and 117.79 +/- 11.57 vs 85.71 +/- 12.11 mg/dl, respectively), whereas pregnancy rate and blood concentrations of HDL and LDL were not affected by treatment (p > 0.05). Addition of corn oil to the supplement stimulated ovarian activity and increased serum concentrations of progesterone and cholesterol in grazing B. taurus x B. indicus cows with low body condition score showing postpartum anoestrus.

    Prenatal diagnosis (PND) is an important issue in the comprehensive care of haemophiliacs. As a consequence of technological progress made in the field of PND, the early detection of an affected fetus provides the expectant couple with a chance to terminate pregnancy. This study was undertaken to assess the attitudes of two different haemophilic populations in Iran and Italy towards PND and termination of pregnancy. This study series included 59 Iranians (38 haemophilia A patients and 21 mothers) and 50 Italians (27 haemophilia A patients, 16 mothers and seven fathers). All the 109 participants received a questionnaire including demographic characteristics and evaluating the psychological effects stemming from PND and termination of pregnancy. Approximately 84.7% of the Iranians and 35.4% of the Italians were not familiar with the possibilities afforded by PND for haemophilia (P < 0.001). Termination of pregnancy appeared to be accepted by 58.2% of the Iranian and 16.7% of the Italian participants (P < 0.001). The greater rate of acceptability of abortion in Iranians may be due to differences in the quality of patient care in the two countries.

    Use of antiepileptic drugs (AEDs) in pregnant women with epilepsy (WWE) is associated with an increased risk of major congenital malformations (MCM). Previous studies have suggested that WWE who had a malformation in their index pregnancy were at an increased risk of recurrence in future pregnancies. We aimed to assess the risk of recurrence of MCM in 1,616 WWE from Kerala Registry of Epilepsy and Pregnancy. The pregnancy outcome of women (n = 246) with two prospective pregnancies in the registry were analyzed. They had partial seizures with or without generalization (57.3%) or generalized seizures (42.7%). Polytherapy was used in 26.4% (index pregnancy) and 23.6% (follow-up pregnancy). The mean dosage of AED for valproate was 498 mg/day and carbamazepine was 555 mg/day. The malformation rate in the index pregnancy was 8.5% (21/246) and in the follow-up pregnancy was 8.9% (22/246) with only one recurrence. There was no increased risk of MCM in follow-up pregnancy for those who had MCM in the index pregnancy (p = 0.70; OR 0.49; 95% CI 0.06-3.80). The use of any specific drug, continuation of the same drug or a change in drug therapy between two pregnancies did not alter the recurrence risk.

    Systemic lupus erythematosus (SLE) is mainly a disease of fertile women and the coexistence of pregnancy is by no means a rare event. How SLE and its treatment affect pregnancy outcomes is still a matter of debate. We performed a retrospective analysis of 41 SLE patients (55 pregnancies) who were followed at our university hospital from January 2000 to December 2009. The mean age of patients was 30.6±4.8 years and mean disease duration was 6.6±5.3 years. After exclusion of artificial abortions, live birth rate was 84%. Significantly, more women with stillbirth pregnancies were complicated with antiphospholipid syndrome (APS) than women with live birth pregnancies (two of eight stillbirth pregnancies (25%) versus one of 42 live birth pregnancies (2%); p=0.014) and hypocomplementemia at conception (four of eight stillbirth pregnancies (50%) versus six of 42 live birth pregnancies (14%); p=0.021). Compared with nonrenal pregnancies, renal pregnancies were younger at SLE disease onset, had a lower positivity of anti-RNP antibody, and were more complicated with pregnancy-induced hypertension. Past maximum dose of prednisolone, the dose of prednisolone at conception, and percentage of past steroid pulse therapy were higher in renal pregnancies. Outcomes of pregnancies were not significantly different both for mothers and for infants between renal and nonrenal pregnancies. We conclude that it is necessary to provide SLE mothers with the proper information before pregnancy. Women with APS or hypocomplementemia should be regarded with particular attention. Optimal management of mothers and infants requires collaborative efforts of rheumatologists and obstetricians.

    2016-06-01

    Primary hyperparathyroidism (PHPT) is one of the most common endocrine disorders in the general population but is rarely diagnosed during pregnancy. Symptoms of gestational PHPT may be unrecognized, or masked by physiological changes in calcium homeostasis associated with pregnancy. Gestational PHPT may have severe consequences for both mother and fetus. However, nowadays, gestational PHPT is usually diagnosed in earlier stages and milder forms, with low complication rates. Treatment should be individually tailored according to gestational age, the severity of hypercalcemia, and the risk-benefit balance. The conservative approach is preferred in mild forms, whereas surgery, usually performed during the second trimester, is reserved for symptomatic hypercalcemic PHPT. Given the young age of the patients, genetic causes should be considered.

    2016-01-01

    Pregnant women with known or suspected cardiovascular disease (CVD) often require cardiovascular imaging during pregnancy. The accepted maximum limit of ionising radiation exposure to the foetus during pregnancy is a cumulative dose of 5 rad. Concerns related to imaging modalities that involve ionising radiation include teratogenesis, mutagenesis and childhood malignancy. Importantly, no single imaging study approaches this cautionary dose of 5 rad (50 mSv or 50 mGy). Diagnostic imaging procedures that may be used in pregnancy include chest radiography, fluoroscopy, echocardiography, invasive angiography, cardiovascular computed tomography, computed tomographic pulmonary angiography, cardiovascular magnetic resonance (CMR) and nuclear techniques. Echocardiography and CMR appear to be completely safe in pregnancy and are not associated with any adverse foetal effects, provided there are no general contra-indications to MR imaging. Concerns related to safety of imaging tests must be balanced against the importance of accurate diagnosis and thorough assessment of the pathological condition. Decisions about imaging in pregnancy are premised on understanding the physiology of pregnancy, understanding basic concepts of ionising radiation, the clinical manifestations of existent CVD in pregnancy and features of new CVD. The cardiologist/physician must understand the indications for and limitations of, and the potential harmful effects of each test during pregnancy. Current evidence suggests that a single cardiovascular radiological study during pregnancy is safe and should be undertaken at all times when clinically justified. In this article, the different imaging modalities are reviewed in terms of how they work, how safe they are and what their clinical utility in pregnancy is. Furthermore, the safety of contrast agents in pregnancy is also reviewed.

    This study evaluated the effect of different doses of eCG (control, 300 or 400 IU) administered at progesterone (P4) device removal in suckled Bos taurus beef cows undergoing a timed artificial insemination (TAI) protocol. A total of 966 cows received a P4 insert and 2.0 mg intramuscular estradiol benzoate at the onset of the synchronization. After 9 days, P4 insert was removed, and 12.5 mg of dinoprost tromethamine and 1 mg of estradiol cypionate were administered, followed by TAI 48 hours later. Then, the cows received one of three treatments as follows: control (n = 323), 300 (n = 326), or 400 IU of eCG (n = 317). A subset (n = 435) of cows in anestrus had their ovaries evaluated using ultrasound at the time of P4 removal and at TAI. Data were analyzed by orthogonal contrasts (C): C1 (eCG effect) and C2 (eCG dose effect). Estrous occurrence (control = 53.7%, 300 IU = 70.6%, and 400 IU = 77.0%) and pregnancy per artificial insemination (control = 29.7%, 300 IU = 44.8%, and 400 IU = 47.6%) were improved by eCG treatment (C1; P = 0.0004 and P < 0.0001, respectively). Furthermore, the cows receiving eCG presented larger follicles at TAI (control = 13.5 ± 0.3 mm, 300 IU = 14.0 ± 0.2 mm, and 400 IU = 15.1 ± 0.3 mm; P < 0.0001; C1). However, there was no effect of eCG dose on any response variables studied (C2; P > 0.15). In conclusion, the eCG treatment administered at the time of P4 removal increased the occurrence of estrus, the larger follicles at TAI, and pregnancy per artificial insemination of suckled B taurus beef cows. Despite the greater occurrence of estrus in noncyclic cows receiving 400 IU of eCG, both eCG doses (300 and 400 IU) were equally efficient to improve pregnancy to artificial insemination.

    CONTEXT Native Hawaiians experience the highest reported rate of unintended pregnancy of any ethnic group in Hawaii. Understanding the context in which they make decisions that influence pregnancy and pregnancy planning is essential to reducing this rate. METHODS A qualitative study was carried out in partnership with a community health center serving a large Native Hawaiian population to explore how Native Hawaiians conceptualize pregnancy and pregnancy planning. Between August and October 2013, semistructured interviews were conducted with 10 diverse key informants from the Hawaiian community. Content analysis was used to identify themes and patterns that emerged from the interviews. RESULTS Core Hawaiian values of children and family strongly aff ect how Native Hawaiians view pregnancy, pregnancy planning and unintended pregnancies. ‘Ohana (families) are large and characterized by tremendous support, which is perceived to lessen the burden of an unintended pregnancy. Pregnancies, whether planned or not, are seen as blessings because children are highly valued. Because of these concepts, there is an expectation for women to continue unplanned pregnancies. Although Hawaiians ascribe value to planning pregnancies and hope that children are born under what they identify as ideal circumstances, they acknowledge that these circumstances are not necessary and often do not occur. CONCLUSION The concepts of family and children serve as core values to Native Hawaiians and are linked to the ways in which they view pregnancy and pregnancy planning. PMID:26684902

    1979-02-01

    Legal abortions have reduced the number of miscarriages by 20%, and of abandoned children by 56%; but at the same time, can be hazardous to the mother both initially (loss of blood, punctured uterus, damaged cervix) and later (infections in the reproductive system, infertility, extrauterine pregnancy, psychological disorders). From 1968 to 1975, 12,795 mothers and their newborns were studied: group 1 (24.8%), were mothers who have had abortions prior to 1st delivery; group 2 (42.3%), mothers having a first delivery with no previous miscarriages or abortions; and group 3 (32.9%), mothers of 2 or more children who had abortions afterwards. Abortion prior to first delivery increased the number of complications (54.4%) during pregnancy (liver and kidney problems, bacterial and viral infections), and during delivery (dirty amniotic fluid, bag of waters ruptured prematurely, pathology of the placenta and membranes, pathology of the umbilical cord). 10% of the deliveries where the mother had a previous history of abortion required medical intervention. Intrauterine dystrophy had occurred in 17% cases and the incidence of premature births was greater, 16%. 29.2% of the infants were in poor condition at delivery according to the Apgar scale (under 4 points) and 42.4% manifested disturbances in environment adaptability. The neonatal mortality rate 6.6% was twice that of the infants from the other 2 groups. The authors conclude that abortions are a threat to the health of mothers and during subsequent pregnancies, endanger the fetus and the newborn. Abortion cannot be regarded as a means of family planning. (Summaries in RUS, ENG).

  6. Improved pregnancy rate in human in vitro fertilization with the use of a medium based on the composition of human tubal fluid.

    PubMed

    Quinn, P; Kerin, J F; Warnes, G M

    1985-10-01

    Significantly more mouse zygotes developed to blastocysts in culture in a medium formulated on the composition of human tubal fluid (HTF) than in modified Tyrode's medium (T6). In a randomized 2 X 2 factorial trial of human in vitro fertilization that compared the two media and culture under oil versus culture in loosely capped tubes, significantly more clinical pregnancies (30% of 60 transfers) were obtained with HTF medium than with T6 medium (11% of 53 transfers). Decreasing the K+ content of HTF medium to that present in T6 medium significantly decreased the number of mouse zygotes that developed in culture. Modifying Ca++ levels had no effect. It is therefore likely that the higher K+ content in HTF medium is primarily responsible for the superiority of HTF medium over T6 medium, but other differences in the composition of the two media could contribute to the results observed.

    1991-07-01

    After 50 hours of small group participation during 9 weeks, 91 young adults rated each same-group member's conduct on SYMLOG's dimensions of dominance, friendliness, and task-orientedness. Earlier, they made similar ratings twice, several weeks apart, on separate measures of self-acceptance and acceptance of others. Individuals' mean SYMLOG dominance ratings by group peers correlated much more highly with aggregated ratings for self-acceptance (.83) than for other-acceptance (.02), while SYMLOG friendliness correlated more positively with acceptance of others (.85) than with self-acceptance (.05). Self-ratings yielded parallel, but weaker associations. After attenuation corrections, these divergent approaches to assessing the interpersonal domain's central dimensions yielded empirically equivalent results. Both methods provide measures relevant to small group processes.

    Lewey, Jennifer; Haythe, Jennifer

    2014-08-01

    Cardiomyopathy during pregnancy is uncommon but potentially catastrophic to maternal health, accounting for up to 11% of maternal deaths. Peripartum cardiomyopathy is diagnosed in women without a history of heart disease 1 month before delivery or within 5 months postpartum. About half of all women will have full myocardial recovery within 6 months of diagnosis, but complications such as severe heart failure or death are not rare. African-American women have higher rates of diagnosis and adverse events. Women with preexisting cardiomyopathy, such as dilated or hypertrophic cardiomyopathy, followed closely during pregnancy often tolerate pregnancy and delivery. Risk factors for adverse outcomes include functional status at baseline, severity of systolic dysfunction or outflow tract gradient, or history of prior cardiac event, such as arrhythmia or stroke. The level of brain natriuretic peptide (BNP) can be used to risk stratify women for adverse events. Pregnant women with cardiomyopathy should be followed closely by a multidisciplinary team comprised of nurses, obstetricians, neonatologists, cardiologists, anesthesiologists, and cardiac surgeons.

    increased need for medical and social support. The Technology Being Reviewed IVF was first developed as a method to overcome bilateral Fallopian tube obstruction. The procedure includes several steps: (1) the woman’s egg is retrieved from the ovaries; (2) exposed to sperm outside the body and fertilized; (3) the embryo(s) is cultured for 3 to 5 days; and (4) is transferred back to the uterus. IFV is considered to be one of the most effective treatments for infertility today. According to data from the Canadian Assisted Reproductive Technology Registry, the average live birth rate after IVF in Canada is around 30%, but there is considerable variation in the age of the mother and primary cause of infertility. An important advantage of IVF is that it allows for the control of the number of embryos transferred. An elective single embryo transfer in IVF cycles adopted in many European countries was shown to significantly reduce the risk of multiple pregnancies while maintaining acceptable birth rates. However, when number of embryos transferred is not limited, the rate of IVF-associated multiple pregnancies is similar to that of other treatments involving ovarian stimulation. The practice of multiple embryo transfer in IVF is often the result of pressures to increase success rates due to the high costs of the procedure. The average rate of multiple pregnancies resulting from IVF in Canada is currently around 30%. An alternative to IVF is IUI. In spite of reported lower success rates of IUI (pregnancy rates per cycle range from 8.7% to 17.1%) it is generally attempted before IVF due to its lower invasiveness and cost. Two major drawbacks of IUI are that it cannot be used in cases of bilateral tubal obstruction and it does not allow much control over the risk of multiple pregnancies compared with IVF. The rate of multiple pregnancies after IUI with COS is estimated to be about 21% to 29%. Ontario Health Insurance Plan Coverage Currently, the Ontario Health Insurance Plan covers

    Adolescent childbearing increased 16% over 1986-90 in the Southern region of the US from 38.4 to 44.6 births/1000 girls aged 15-17; adolescent birth rates declined only in Oklahoma at the rate of 1%. Southern states spent more than $5.7 billion in Aid to Families with Dependent Children, Medicaid, and food stamps in 1991 to support families started by adolescent mothers, but federal and state spending combined for the primary prevention of adolescent pregnancy totalled only $110 million in the same states. Public expenditures related to adolescent childbearing in Alabama in fiscal year 1991 totalled more than $117 million, yet less than $1.5 million is spent on preventing teen pregnancy. The author stresses the need for stronger state commitment, leadership, and funds for programs to prevent pregnancy. Thus far, Alabama has definitely not done enough to address the HIV and AIDS pandemic.

    Anestrous and lactating Bos taurus by Bos indicus crossbred cows with minimum body condition were studied to determine the efficacy of GnRH+PGF 2alpha combinations for induction of estrus and/or ovulation on pregnancy rate during the months of the year when temperatures are greater. On day 0 (start of treatment), cows were assigned randomly to either treatment or control groups. Treated cows (n = 74) received i.m. 200 microg of GnRH on day 0 and 150 microg of PGF 2alpha 7 days later (day 7). On day 7, treated cows were equally distributed to each of three protocols: (1) Select Synch (n = 25), artificial insemination (AI) 12 h after exhibiting estrus from day 7 (PGF 2alpha injection) until day 12; (2) Ovsynch (n = 24), 200 microg of GnRH at 48 h after PGF 2alpha (day 9) + timed-AI (TAI) 16-20 h later; (3) CO-Synch (n = 25), 200 microg of GnRH + TAI at 48 h after PGF 2alpha (day 9). Control cows (n = 25) received no treatment + AI 12 h after exhibiting estrus from days 0 to 12. Detection of estrus was performed daily during the early morning and evening hours from days 0 to 7 in all the cows, and from days 7 to 12 in the cows treated with Select Synch and in the control group, with the aid of a sterilized bull. Palpation per rectum and transrectal ultrasonography were used on days -30, -20, -10 and 0 to confirm anestrus (absence of CL and no signs of estrus at each evaluation) but with ovarian follicles > or = 10 mm on day 0. Pregnancy rate was 0% for Select Synch, 21% for Ovsynch and 28% for CO-Synch (P < 0.05). In conclusion, the Ovsynch and CO-Synch protocols resulted in greater pregnancy rates compared with the Select Synch protocol in Bos taurus/Bos indicus cows with minimum body condition that were anestrous and lactating during the summer months in a tropical environment.

    Two experiments were conducted to evaluate the effect of different ovulation inducers on E-17β plasma concentrations, synchronized ovulations and pregnancy rates. In Experiment 1, cows received a progesterone intravaginal device (PID) with 1 g of progesterone (P4) plus 2 mg of estradiol benzoate (EB) (day 0). At PID removal (day 8), cows received 0.150 mg of D-cloprostenol and were randomly assigned to four treatment groups (n = 10/treatment): Group ECP: 1 mg of estradiol cypionate at PID removal, Group EB: 1 mg of EB 24 hr after PID removal, Group GnRH: 10 μg of GnRH 48 hr after PID removal, Group ECP-GnRH: 1 mg of ECP at PID removal plus 10 μg of GnRH 48 hr later. Ultrasonographic examinations were performed to detect the dominant follicle and ovulation. GnRH-treated cows ovulated later (p < .05) compared to ECP- and ECP+GnRH-treated cows. There were effects of treatment, time and their interaction on E-17β concentrations (p < .05). ECP treatment affected plasma E-17β concentration, which increased earlier and decreased later compared to treatments without ECP. In Experiment 2, cows received (i) ECP: n = 126; (ii) EB: n = 126; (iii) GnRH: n = 136; (iv) ECP+GnRH: n = 139; FTAI was performed 48-50 hr after PID removal. Pregnancy rates did not differ among ovulation inducers (p > .05; ECP: 54.0%, 68/126; EB: 49.2%, 62/126; GnRH: 40.4%, 55/136; ECP+GnRH: 43.9%, 61/139). In conclusion, ECP administration (ECP and ECP+GnRH treatments) affected E-17β concentrations, determining its earlier increase and later decrease compared to treatments without ECP (EB and GnRH treatments). ECP+GnRH-treated cows achieved the best distribution of ovulations without affecting pregnancy rates.

    Acne vulgaris is a common disease of the pilosebaceous unit and affects adolescents and adults. Because high-quality guidelines regarding treatment of acne in pregnancy are scarce, management of this condition can be challenging. We describe the safety profile of common therapies and outline approaches based on available evidence. Topical azelaic acid or benzoyl peroxide can be recommended as baseline therapy. A combination of topical erythromycin or clindamycin with benzoyl peroxide is recommended for inflammatory acne. Oral erythromycin or cephalexin is generally considered safe for moderate to severe inflammatory acne when used for a few weeks. A short course of oral prednisolone may be useful for treating fulminant nodular cystic acne after the first trimester. In general, topical and oral antibiotics should not be used as monotherapy, but combined with topical benzoyl peroxide to decrease bacterial resistance. Oral retinoids are teratogenic and absolutely contraindicated for women who are pregnant or considering pregnancy. Although some complementary therapies including micronutrients and nonpharmacologic treatments seem to be well tolerated, limited data exist regarding their safety and efficacy, and they are not currently recommended during pregnancy. The risk-to-benefit ratio, efficacy, acceptability, and costs are considerations when choosing a treatment for acne in pregnancy.

    Younger maternal age at delivery has been linked to adverse reproductive outcomes. Pregnancy complicated by type 1 diabetes mellitus (T1DM) is also associated with adverse pregnancy outcomes. Optimising diabetic glycaemic control prior to pregnancy is known to reduce the rate of congenital abnormalities and improve pregnancy outcomes. Teenage pregnancies are not usually planned and little data exist on teenage pregnancy complicated by T1DM. We sought to identify the glycemic control achieved in teenage pregnancy with T1DM and to clarify if there is an associated increase in adverse pregnancy outcomes compared to those seen in older women with T1DM. We compared outcomes in 18 teenagers (TG) with 582 older women with T1DM (CON) from 1995-2007. TG booked to the combined diabetes-obstetrical service at a median gestational age of 11 weeks (range 6-22) compared to 7 weeks in CON (range 4-40, p < 0.02). Glycaemic was worse in TG compared to CON at 13, 26 and 35 weeks gestation, despite higher insulin doses. First trimester miscarriage rate did not differ between groups. Major congenital anomaly rate was 6.2% (1/16) compared to 3.2% in CON. This preliminary study has demonstrated that pregnant teenage women with T1DM book later to specialised care and have worse glycaemic control in pregnancy compared to older women with T1DM. This group also appear to be more insulin resistant than older women in early pregnancy. Our data would suggest that teenagers with type 1 diabetes mellitus may constitute a high-risk group for adverse pregnancy outcomes.

    The skin changes in pregnancy can be either physiological (hormonal), changes in pre-existing skin diseases or development of new pregnancy specific dermatoses. Pregnancy-specific skin dermatoses include an ill-defined heterogeneous group of pruritic skin eruptions which are seen only in pregnancy. These include atopic eruption of pregnancy, polymorphic eruption of pregnancy, pemphigoid gestationis and intrahepatic cholestasis of pregnancy. Atopic eruption of pregnancy is the most common of these disorders. Most skin eruptions resolve postpartum and require only symptomatic treatment. Antepartum surveillance is recommended for patients with pemphigoid gestationis and intrahepatic cholestasis of pregnancy as they carry fetal risk. This article deals with the classification, clinical features and treatment of the specific dermatoses of pregnancy. PMID:19882004

    The purpose of this study was to determine whether exposure to stressful life events was associated with changes in levels of circulating cortisol during pregnancy in a population of 603 pregnant women. The participating pregnant women filled out a questionnaire and collected a morning and evening sample of saliva in early pregnancy (median 14th gestational week) and in late pregnancy (median and 30th gestational week). They were asked to report the number of life events experienced during first and second trimester, respectively, and were asked to rate the intensity of the experienced events. Complications related to the pregnancy such as vaginal bleeding and suspected growth retardation were registered and the women were asked about concerns about their pregnancy. The salivary samples were analyzed for cortisol and the levels were higher in late than in early pregnancy. In late pregnancy women exposed to more than one life event or were concerned about pregnancy complications during second trimester had a higher evening cortisol level, whereas morning values were unaffected. After adjustment for smoking women who experienced more than one very stressful life event had 27% higher evening cortisol concentrations (95% confidence intervals: 1-59%). Women with worries about pregnancy complications had 27% (95% confidence intervals: 2-57%) higher levels. In early pregnancy women reporting stressful life events did not have higher evening cortisol levels, but tended to have a blunted morning HPA response. In conclusion, we found differences in the associations between chronic stress in early and late pregnancy and cortisol levels indicating that the response to chronic stress is dependent on the stage of the pregnancy.

    This study aimed to evaluate the opinions and practices of general dentists in Connecticut regarding dental care during pregnancy. A survey was mailed to Connecticut general dentists to acquire data regarding age, gender, training, type of practice, years in practice, payment types accepted, procedures provided for pregnant women according to trimester, provider comfort level with treating pregnant patients, reasons for not treating pregnant patients, and provider opinions about dental care during pregnancy. The response rate was 42%, yielding a sample of 116 dentists. The majority of respondents (97%) reported treating pregnant patients; however, only 45% felt "very comfortable" treating these patients. All dentists in the sample agreed that physicians need to include an oral health evaluation and appropriate referral for patients' prenatal care. However, 70% of respondents had never received a dental referral for a pregnant patient. The majority of dentists favored providing dental treatment during the second trimester of pregnancy. Most dentists (77%) would take a radiograph for a patient 10 weeks into the pregnancy seeking treatment for dental pain, but only 2% would take routine radiographs regardless of the pregnancy trimester. There was a lack of consensus about medications dentists reported acceptable to prescribe for pregnant patients, and female dentists were significantly less likely than males to prescribe ibuprofen (P < 0.05). At least half of the respondents reported not being completely comfortable treating pregnant patients. Further, many dentists appear to not follow medication prescribing guidelines for this population. While additional research is needed, these initial results indicate that additional education regarding the treatment of pregnant patients would be a beneficial addition to dental school and continued education course curricula.

    2006-12-01

    The purpose of this review was to examine the impact of varying degrees of renal insufficiency on pregnancy outcome in women with chronic renal disease. Our search of the literature did not reveal any randomized clinical trials or meta-analyses. The available information is derived from opinion, reviews, retrospective series, and limited observational series. It appears that chronic renal disease in pregnancy is uncommon, occurring in 0.03-0.12% of all pregnancies from two U.S. population-based and registry studies. Maternal complications associated with chronic renal disease include preeclampsia, worsening renal function, preterm delivery, anemia, chronic hypertension, and cesarean delivery. The live birth rate in women with chronic renal disease ranges between 64% and 98% depending on the severity of renal insufficiency and presence of hypertension. Significant proteinuria may be an indicator of underlying renal insufficiency. Management of pregnant women with underlying renal disease should ideally entail a multidisciplinary approach at a tertiary center and include a maternal-fetal medicine specialist and a nephrologist. Such women should receive counseling regarding the pregnancy outcomes in association with maternal chronic renal disease and the effect of pregnancy on renal function, especially within the ensuing 5 years postpartum. These women will require frequent visits and monitoring of renal function during pregnancy. Women whose renal disease is further complicated by hypertension should be counseled regarding the increased risk of adverse outcome and need for blood pressure control. Some antihypertensives, especially angiotensin-converting enzyme inhibitors and angiotensin-receptor blockers, should be avoided during pregnancy, if possible, because of the potential for both teratogenic (hypocalvaria) and fetal effects (renal failure, oliguria, and demise).

    The US has one of the highest teenage pregnancy rates in the industrialized world, over 1,000,000 a year. This can add to social problems including poverty, unemployment, family breakup, juvenile crime, school dropouts, and child abuse. In several studies various approaches have been developed and it is concluded that teens must not only be given the knowledge to avoid teen pregnancies, but the motivation to do so. Sex education is an important part of pregnancy prevention, but few programs go beyond the facts of reproduction and less than 14% of them are 40 hours long. Studies have shown mixed results as to the effect of education on teen pregnancy. There are many programs that have been developed by different communities, including computer programs and youth service agencies. Religious groups also play an important part in sex education and they have some distinct advantages in affecting teens' sexual values and activities. Education programs for teen's parents appear to be very important since studies show when sexuality is discussed at home, the teens begin activity later and use birth control more. Clinics have had difficulty recruiting and retaining teen patients and devote special attention to establishing a rapport with them. The school-based clinic is becoming increasingly popular and can provide birth control counseling, contraceptives, family planning clinic referral, examinations, pregnancy testing, and prenatal care. There success is due to confidentiality, convenience, and comprehensive service. However, since nearly all efforts on teen pregnancy prevention are directed at girls, 1/2 of those involved in teen pregnancies--males--are not participating in programs. This must change for longterm success of these programs and also the involvement of the community and media.

  9. Monitoring outcomes of pregnancy following drug exposure: a company-based pregnancy registry program.

    Women who discover they are pregnant after exposure to a drug and pregnant women who have a condition that requires continued treatment during pregnancy are told to balance the benefits and risks of the exposure to justify continuation of treatment, discontinuation of treatment or, possibly, pregnancy termination. However, there are limited data available to inform decision-making. The Merck Pregnancy Registry Program is a company-run pregnancy registry whose objective is to acquire and analyse information on drug exposures and pregnancy outcomes to better describe the safety profile of Merck products used during pregnancy. Information is collected from women and healthcare providers who call to report drug exposure during pregnancy. Prospective pregnancies are followed up to outcome and data are collected via questionnaires, telephone calls and a review of medical records. Reports are classified as prospective (information received prior to knowledge of pregnancy outcome) or retrospective (received after the outcome is known). Congenital anomaly reports are assessed for timing of exposure, maternal age and medical history, biological plausibility and concomitant medication exposures. Rates of pregnancy outcomes and birth defects in the prospective cohort are computed and confidence intervals are calculated to reflect the strength of the finding based on the sample size. Rates of pregnancy outcomes in the Pregnancy Registry are compared with the rates of pregnancy outcomes in the general US population and, if available, in subpopulations with the relevant disease states. The limitations of post-marketing surveillance are well known as voluntary reporting of individuals and healthcare professionals is known to be subject to various types of bias. Small sample size is another major limitation. However, the strength of the registry lies in its ability to gather pregnancy outcome reports early in the life of a product and to recognise and analyse unusual birth defects

    Systemic lupus erythematosus (SLE) is a multisystem autoimmune disease that primarily affects women during their reproductive years. The interaction between SLE and pregnancy remains debated. The objective of this study was to analyze the fetal and maternal outcomes of Chinese women with SLE. A total of 109 pregnancies in 83 SLE patients from June 2004 to June 2014 at a tertiary university hospital were reviewed retrospectively. Patients’ characteristics, clinical and laboratory data during pregnancy were obtained from electronic medical records. After exclusion of elective abortions, the live birth rate was 61.5%. Significantly, APS (antiphospholipid syndrome), disease activity, hypertension, hypocomplementemia, thrombocytopenia, and anemia during pregnancy were more commonly observed in fetal loss pregnancies than in live birth pregnancies. Compared to the 64 women with a history of SLE, 19 women with new-onset lupus during pregnancy had worse pregnancy outcome. Furthermore, the 64 patients with a history of SLE were divided into lupus nephritis group and SLE group (non-renal involvement). We found that the lupus nephritis group had worse maternal outcome than the SLE group. We conclude that new-onset lupus during pregnancy predicts both adverse maternal and fetal outcomes, while a history of lupus nephritis predicts adverse maternal outcomes. It is essential to provide SLE women with progestational counseling and regular multispecialty care during pregnancy. PMID:27442513

    Isolated complete congenital heart block (CHB) in the majority of cases is associated with the presence of autoantibodies to SSA (Ro) and SSB (La) antigens in the maternal serum. The prognosis is less favorable in fetuses with a ventricular rate < 55bpm. We have reported a case of a fetus with an isolated non-autoimmune CHB with an extremely low ventricular rate (34bpm) in which the outcome was favorable. In the neonate the non-compaction of the myocardium was diagnosed.

    During pregnancy immunological, metabolic, hormonal and vascular changes occur, and can cause specific skin diseases. The specific dermatoses of pregnancy have undergone numerous changes in nomenclature and classification, partly due to advances in the knowledge of the pathogenesis of these skin diseases. Currently the following diseases are considered specific dermatoses of pregnancy: pemphigoid gestations, polymorphic eruption of pregnancy, intrahepatic cholestasis of pregnancy and atopic eruption of pregnancy. Timely diagnosis and specific and safe treatment are essential to prevent complications which, although rare, may be associated with significant maternal-fetal comorbidity.

    To evaluate whether periconceptional exposure to oral contraceptives (OCs) increased adverse pregnancy outcomes, 136 pregnant women taking OCs within the periconceptional period were identified at the Korean Motherisk Program. Of them, 120 pregnant women accepted to participate in their study and were followed up until completion of the pregnancy. A control group of 240 age- and gravidity-matched pregnant women exposed to non-teratogen drugs for at least 1 month before pregnancy was also included. The median gestational age at delivery was 39.1 (27.0-41.0) weeks in the exposed group and 39.3 (27.4-42.0) weeks in the control group (P = 0.19). In the exposed group, 7.1% of babies were born with low birth weight versus 2.6% in the control group (P = 0.068). The number of preterm deliveries or babies born large for gestational age did not differ between the two groups. In the exposed group, the rate of birth defects was 3.2% (n = 3/99) versus 3.6% (n = 7/193) in the control group (P = 1.0). There were 15 women who took high doses of progesterone (emergency contraception) and no adverse fetal outcomes were observed. In conclusion, periconceptional exposure to OCs does not appear to increase the risk for adverse pregnancy outcomes.

    2014-01-01

    Background Diagnostic ultrasound is a sophisticated electronic technology, which utilises pulses of high frequency sound to produce an image. Diagnostic ultrasound examination may be employed in a variety of specific circumstances during pregnancy such as after clinical complications, or where there are concerns about fetal growth. Because adverse outcomes may also occur in pregnancies without clear risk factors, assumptions have been made that routine ultrasound in all pregnancies will prove beneficial by enabling earlier detection and improved management of pregnancy complications. Routine screening may be planned for early pregnancy, late gestation, or both. The focus of this review is routine early pregnancy ultrasound. Objectives To assess whether routine early pregnancy ultrasound for fetal assessment (i.e. its use as a screening technique) influences the diagnosis of fetal malformations, multiple pregnancies, the rate of clinical interventions, and the incidence of adverse fetal outcome when compared with the selective use of early pregnancy ultrasound (for specific indications). Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (September 2009). Selection criteria Published, unpublished, and ongoing randomised controlled trials that compared outcomes in women who experienced routine versus selective early pregnancy ultrasound (i.e. less than 24 weeks’ gestation). We have included quasi-randomised trials. Data collection and analysis Two review authors independently extracted data for each included study. We used the Review Manager software to enter and analyse data. Main results Routine/revealed ultrasound versus selective ultrasound/concealed: 11 trials including 37505 women. Ultrasound for fetal assessment in early pregnancy reduces the failure to detect multiple pregnancy by 24 weeks’ gestation (risk ratio (RR) 0.07, 95% confidence interval (CI) 0.03 to 0.17). Routine scan is associated with a reduction in

    Porphyrias are rare metabolic diseases caused by enzymatic defects of the haeme biosynthesis. Association of pregnancy and acute porphyria is rare, but mortality rate among pregnant women from acute attack has been reported up to 42%. This paper presents a patient with pregnancy complicated by intermittent hepatic porphyria with good perinatal outcome. The pattern of the attack in pregnancy varies individually and it makes porphyric pregnancies a challenge. Previously diagnosed porphyria patients should be closely monitored during pregnancy and diagnosis of acute porphyria must be also considered in all pregnant women with unexplained abdominal pain.

    Extensive evidence exists regarding the efficacy and acceptability of medical abortion through 63 days since last menstrual period (LMP). In Mexico City's Secretariat of Health (SSDF) outpatient facilities, mifepristone-misoprostol medical abortion is the first-line approach for abortion care in this pregnancy range. Recent research demonstrates continued high rates of complete abortion through 70 days LMP. To expand access to legal abortion services in Mexico City (where abortion is legal through 12 weeks LMP), this study sought to assess the efficacy and acceptability of the standard outpatient approach through 70 days in two SSDF points of service. One thousand and one women seeking pregnancy termination were enrolled and given 200 mg mifepristone followed by 800 μg misoprostol 24-48 hours later. Women were asked to return to the clinic one week later for evaluation. The great majority of women (93.3%; 95% CI: 91.6-94.8) had complete abortions. Women with pregnancies ≤ 8 weeks LMP had significantly higher success rates than women in the 9th or 10th weeks (94.9% vs. 90.5%; p = 0.01). The difference in success rates between the 9th and 10th weeks was not significant (90.0% vs. 91.2%; p = 0.71). The majority of women found the side effects (82.9%) and the use of misoprostol (84.4%) to be very acceptable or acceptable. This study provides additional evidence supporting an extended outpatient medical abortion regimen through 10 weeks LMP.

    1993-11-01

    Neurofibromatosis is one of the most frequent genetic diseases in humans. Pregnancy in neurofibromatosis patients is, however, less common. Most current information on pregnancy and neurofibromatosis is derived from case reports, which may not reflect the true situation. In the past 15 years only two series of pregnant neurofibromatosis patients were reported in the English-language literature. We present our experience with 34 pregnancies in nine neurofibromatosis patients who delivered at our medical center. While fertility does not seem to be impaired in neurofibromatosis, these patients experience a higher-than-expected rate of first-trimester spontaneous abortions (20.7%), stillbirths (8.7%) and intrauterine growth retardation (13.0%). A high rate of cesarean section (26%) was also observed in our series. We conclude that pregnant neurofibromatosis patients constitute a high-risk group, in danger of developing life-threatening complications. However, with proper antenatal care, most pregnant neurofibromatosis patients can deliver safety if the pregnancy continues beyond the first trimester.

  1. Accepting space radiation risks.

    PubMed

    Schimmerling, Walter

    2010-08-01

    The human exploration of space inevitably involves exposure to radiation. Associated with this exposure are multiple risks, i.e., probabilities that certain aspects of an astronaut's health or performance will be degraded. The management of these risks requires that such probabilities be accurately predicted, that the actual exposures be verified, and that comprehensive records be maintained. Implicit in these actions is the fact that, at some point, a decision has been made to accept a certain level of risk. This paper examines ethical and practical considerations involved in arriving at a determination that risks are acceptable, roles that the parties involved may play, and obligations arising out of reliance on the informed consent paradigm seen as the basis for ethical radiation risk acceptance in space.

    2009-01-01

    Liver diseases in pregnancy may be categorized into liver disorders that occur only in the setting of pregnancy and liver diseases that occur coincidentally with pregnancy. Hyperemesis gravidarum, preeclampsia/eclampsia, syndrome of hemolysis, elevated liver tests and low platelets (HELLP), acute fatty liver of pregnancy, and intrahepatic cholestasis of pregnancy are pregnancy-specific disorders that may cause elevations in liver tests and hepatic dysfunction. Chronic liver diseases, including cholestatic liver disease, autoimmune hepatitis, Wilson disease, and viral hepatitis may also be seen in pregnancy. Management of liver disease in pregnancy requires collaboration between obstetricians and gastroenterologists/hepatologists. Treatment of pregnancy-specific liver disorders usually involves delivery of the fetus and supportive care, whereas management of chronic liver disease in pregnancy is directed toward optimizing control of the liver disorder. Cirrhosis in the setting of pregnancy is less commonly observed but offers unique challenges for patients and practitioners. This article reviews the epidemiology, pathophysiology, diagnosis, and management of liver diseases seen in pregnancy. PMID:19248187

  5. [Smoking and pregnancy].

    PubMed

    Wenderlein, J M

    1995-10-01

    The medical consultation during pregnancy should include information about smoking and side-stream smoking. More than half of the fetuses are more or less exposed to harmful substances passing the placenta due to smoking of the mother or smoking persons in the direct environment. The danger due to side-stream smoking have to be considered more during the consultation. It is known that toxic substances are concentrated higher in the side-stream smoke than in the main-stream smoke. Due to enzyme induction, smokers can metabolize toxic substances faster than non-smokers or side-stream smokers. Already before a planned pregnancy, it should be pointed out that tobacco smoke contains numerous teratogenic substances which double the risk of fetal malformations. A high consumption of cigarettes induces an increased risk of abortion. An insufficient perfusion of the uterus and the placenta causes an O2-debt with an increased risk for malformations such as schistasis or an increased rate of premature birth. The increased CO content of the maternal blood reduces the O2 transport capacity since CO has an about 200 times greater affinity to hemoglobin than O2. These and other topics of the consultation for pregnant women are important in the interest of the fetus.

  6. Lupus nephritis and renal disease in pregnancy.

    PubMed

    Germain, S; Nelson-Piercy, C

    2006-01-01

    Management of pregnant women with renal disease involves awareness of, and allowance for, physiological changes including decreased serum creatinine and increased proteinuria. For women with systemic lupus erythematosus (SLE), pregnancy increases likelihood of flare. These can occur at any stage, and are more difficult to diagnose, as symptoms overlap those of normal pregnancy. Renal involvement is no more common in pregnancy. Worsening proteinuria may be lupus flare but differential includes pre-eclampsia. In women with chronic renal disease, pregnancy may accelerate decline in renal function and worsen hypertension and proteinuria, with increased risk of maternal (eg, pre-eclampsia) and fetal (eg, IUGR, IUD) complications, strongly correlating with degree of renal impairment peri-conception. Pregnancy success rate varies from 20% to 95% depending on base-line creatinine. Best outcome is obtained if disease was quiescent for >6 months pre-conception. Women on dialysis or with renal transplants can achieve successful pregnancy but have higher maternal and fetal complication rates. Acute on chronic renal failure can develop secondary to complications such as HELLP and AFLP. Management needs to be by a multidisciplinary team involving physicians and obstetricians, ideally beginning with pre-pregnancy counselling. Treatment of flares includes corticosteroids, hydroxychloroquine, azothioprine, NSAIDs and MME Blood pressure is controlled with methyldopa, nifedipine or hydralazine.

    2015-01-01

    Repeat pregnancies with different perinatal outcomes minimize underlying maternal genetic diversity and provide unique opportunities to investigate nongenetic risk factors and epigenetic mechanisms of pregnancy complications. We investigated gestational diabetes mellitus (GDM)-related differential DNA methylation in early pregnancy peripheral blood samples collected from women who had a change in GDM status in repeat pregnancies. Six study participants were randomly selected from among women who had 2 consecutive pregnancies, only 1 of which was complicated by GDM (case pregnancy) and the other was not (control pregnancy). Epigenome-wide DNA methylation was profiled using Illumina HumanMethylation 27 BeadChips. Differential Identification using Mixture Ensemble and false discovery rate (<10%) cutoffs were used to identify differentially methylated targets between the 2 pregnancies of each participant. Overall, 27 target sites, 17 hypomethylated (fold change [FC] range: 0.77-0.99) and 10 hypermethylated (FC range: 1.01-1.09), were differentially methylated between GDM and control pregnancies among 5 or more study participants. Novel genes were related to identified hypomethylated (such as NDUFC1, HAPLN3, HHLA3, and RHOG) or hypermethylated sites (such as SEP11, ZAR1, and DDR). Genes related to identified sites participated in cell morphology, cellular assembly, cellular organization, cellular compromise, and cell cycle. Our findings support early pregnancy peripheral blood DNA methylation differences in repeat pregnancies with change in GDM status. Similar, larger, and repeat pregnancy studies can enhance biomarker discovery and mechanistic studies of GDM. PMID:25676578

    An experiment was designed to evaluate whether expression of oestrus in recipients synchronized with progesterone devices and oestradiol affects pregnancy rates to a fixed-time embryo transfer (FTET). A secondary objective was to determine whether administration of gonadotropin-releasing hormone (GnRH) to those recipients not showing oestrus by 48h after device removal had an effect on pregnancy rates. Mature, non-lactating beef recipients (Bonsmara, Brangus, and Braford; n=729), with a corpus luteum (CL) or a follicle ≥8mm in diameter detected by ultrasonography (Mindray DP 30, Shenzhen, China) and body condition score 2 to 4 (1 to 5 scale) were synchronized in 7 replicates. On Day 0, recipients received a progesterone device (DIB 0.5g, Zoetis, Buenos Aires, Argentina) and 2mg of oestradiol benzoate (Gonadiol, Zoetis). On Day 8, DIB were removed and recipients received 400IU eCG (Novormon 5000, Zoetis) plus 0.5mg of oestradiol cypionate (Cipiosyn, Zoetis) and 500μg of cloprostenol (Cyclase, Zoetis). In addition, all cows were tail-painted on the sacrococcygeal area (CeloTest, Biotay, Buenos Aires, Argentina) at DIB removal and were observed to determine the expression of oestrus, according to the percentage of paint loss 48h later. The animals that showed oestrus (paint loss >30%) were recorded, and those with paint loss ≤30% (not in oestrus) were randomly allocated to receive 100μg of gonadorelin (GnRH; Gonasyn, Zoetis) or no treatment. On Day 17, all recipients were examined by ultrasonography and those with a CL ≥18mm (G1), ≥16 and <18mm (G2), or ≥14 and <16mm (G3) in diameter received in vivo-produced frozen-thawed embryos by direct transfer or fresh in vitro-produced embryos. Pregnancy was diagnosed by ultrasonography at 23 days after FTET, and data were analysed by logistic regression. There were no differences between replicates, in vivo- and in vitro-produced embryos, or operators (P>0.2). However, the proportion of recipients transferred and

    Renal injury or failure may occur in the context of pregnancy requiring special considerations with regard to fetal and maternal health. The condition of pregnancy itself may be a major factor in such injuries. In addition, for many young women previously known to be healthy, pregnancy may be the first presentation for routine urine and blood testing which may yield previously subclinical renal disease. As such, pregnancy may add complexity to considerations in the management of renal disease presenting coincidentally requiring knowledge of the physiologic changes and potential renal disorders that may be encountered during pregnancy.

    Hemodynamic changes occur in pregnancy to prepare for expected blood loss at delivery. Physiologic anemia occurs in pregnancy because plasma volume increases more quickly than red cell mass. Anemia is most commonly classified as microcytic, normocytic, or macrocytic. Iron deficiency anemia accounts for 75% of all anemias in pregnancy. Oral iron supplementation is the recommended treatment of iron deficiency anemia in pregnancy. Parenteral iron and erythropoietin can also be used in severe or refractory cases. Outcomes and treatments for other forms of inherited and acquired anemias in pregnancy vary by disease, and include nutritional supplementation, corticosteroids, supportive transfusions, and splenectomy.

However, acute deterioration in liver function can also be caused by drug overdose, viral infections, and an exacerbation of underlying chronic liver disease. This article provides an overview of the normal liver changes that occur during pregnancy, and summarizes the most common conditions and general management strategies of liver failure during pregnancy.

    With the increase in incidence of ectopic pregnancy over the decades, bilateral ectopic pregnancy is also increasing. It is usually associated with assisted reproductive techniques (ART) but in recent years few cases of spontaneous bilateral ectopic pregnancy have been reported. Gynaecologists should be aware of this and that ultrasonography has limitations in diagnosis. In cases of ectopic pregnancy where contralateral adnexa is not clearly identified on ultrasound and fertility needs to be conserved, patient should be managed by experts in well equipped centres. A case of spontaneous bilateral tubal pregnancy that remained undiagnosed till laparotomy, is described.

    Renal injury or failure may occur in the context of pregnancy requiring special considerations with regard to fetal and maternal health. The condition of pregnancy itself may be a major factor in such injuries. In addition, for many young women previously known to be healthy, pregnancy may be the first presentation for routine urine and blood testing which may yield previously subclinical renal disease. As such, pregnancy may add complexity to considerations in the management of renal disease presenting coincidentally requiring knowledge of the physiologic changes and potential renal disorders that may be encountered during pregnancy.

    The range of pregnancy options available to adolescents each have significant ramifications for future educational and economic achievement. The changing societal context of adolescent pregnancy decision-making are described, and the characteristics of adolescents who choose to terminate their pregnancy, parent their child, or place for adoption are examined. The role of significant others in decision-making and the implications of mandatory parental involvement in pregnancy decision-making is discussed, as well as the roles of schools in promoting the well-being and potential of adolescents considering pregnancy decisions.

  15. Why was Relativity Accepted?

    NASA Astrophysics Data System (ADS)

    Brush, S. G.

    Historians of science have published many studies of the reception of Einstein's special and general theories of relativity. Based on a review of these studies, and my own research on the role of the light-bending prediction in the reception of general relativity, I discuss the role of three kinds of reasons for accepting relativity (1) empirical predictions and explanations; (2) social-psychological factors; and (3) aesthetic-mathematical factors. According to the historical studies, acceptance was a three-stage process. First, a few leading scientists adopted the special theory for aesthetic-mathematical reasons. In the second stage, their enthusiastic advocacy persuaded other scientists to work on the theory and apply it to problems currently of interest in atomic physics. The special theory was accepted by many German physicists by 1910 and had begun to attract some interest in other countries. In the third stage, the confirmation of Einstein's light-bending prediction attracted much public attention and forced all physicists to take the general theory of relativity seriously. In addition to light-bending, the explanation of the advance of Mercury's perihelion was considered strong evidence by theoretical physicists. The American astronomers who conducted successful tests of general relativity became defenders of the theory. There is little evidence that relativity was `socially constructed' but its initial acceptance was facilitated by the prestige and resources of its advocates.

    With over 100 models of unmanned vehicles now available for military and civilian safety, security or rescue applications, it is important to for agencies to establish acceptance testing. However, there appears to be no general guidelines for what constitutes a reasonable acceptance test. This paper describes i) a preliminary method for acceptance testing by a customer of the mechanical and electrical components of an unmanned ground vehicle system, ii) how it has been applied to a man-packable micro-robot, and iii) discusses the value of testing both to ensure that the customer has a workable system and to improve design. The test method automated the operation of the robot to repeatedly exercise all aspects and combinations of components on the robot for 6 hours. The acceptance testing process uncovered many failures consistent with those shown to occur in the field, showing that testing by the user does predict failures. The process also demonstrated that the testing by the manufacturer can provide important design data that can be used to identify, diagnose, and prevent long-term problems. Also, the structured testing environment showed that sensor systems can be used to predict errors and changes in performance, as well as uncovering unmodeled behavior in subsystems.

    Several alternative approaches to address the question {open_quotes}How safe is safe enough?{close_quotes} are reviewed and an attempt is made to apply the reasoning behind these approaches to the issue of acceptability of radiation exposures received in space. The approaches to the issue of the acceptability of technological risk described here are primarily analytical, and are drawn from examples in the management of environmental health risks. These include risk-based approaches, in which specific quantitative risk targets determine the acceptability of an activity, and cost-benefit and decision analysis, which generally focus on the estimation and evaluation of risks, benefits and costs, in a framework that balances these factors against each other. These analytical methods tend by their quantitative nature to emphasize the magnitude of risks, costs and alternatives, and to downplay other factors, especially those that are not easily expressed in quantitative terms, that affect acceptance or rejection of risk. Such other factors include the issues of risk perceptions and how and by whom risk decisions are made.

    The objective of this prospective cohort study was to determine the sensitivity, specificity, accuracy, and predictive value of twin pregnancy diagnosis by rectal palpation and to examine fetal survival, culling rates, and gestational lengths of cows diagnosed with twins. In this prospective study, 5309 cows on 14 farms in California were followed from pregnancy diagnosis to subsequent abortion or calving. The average sensitivity, specificity, accuracy, and predictive value of twin pregnancy diagnosis were 49.3%, 99.4%, 96.0%, and 86.1%, respectively. The abortion rate for single pregnancies of 12.0% differed significantly from those for bicornual twin pregnancies and unicornual twin pregnancies of 26.2% and 32.4%, respectively (P < 0.05). The early calf mortality between cows calving with singles (3.2%) and twins (15.7%) were significantly different (P < 0.005). The difference in fetal survival between single pregnancies and all twin pregnancies resulted in 0.42 and 0.29 viable heifers per pregnancy, respectively. The average gestation for single, bicornual, and unicornual pregnancies that did not abort before drying-off was 278, 272, and 270 days, respectively. Results of this study show that there is an increased fetal wastage associated with twin pregnancies and suggest a need for further research exploring management strategies for cows carrying twins.

    Teenage pregnancy is a global problem and is considered a high-risk group, in spite of conflicting evidence. Our objective was to compare obstetric outcomes of pregnancy in teenagers and older women. This was a retrospective study of case records of pregnancies from August 2000 to July 2001. Girls aged < or =19 years were compared with pregnancy outcomes in older women (19-35 years) in the same hospital. The study took place in the Government General Hospital, Sangli, India, a teaching hospital in rural India, with an annual delivery rate of over 3,500. A total of 386 teenage pregnancies were compared with pregnancies in 3,326 older women. Socioeconomic data, age, number of pregnancies, antenatal care and complications, mode of delivery, and neonatal outcomes were considered. The incidence of teenage pregnancy in the study was 10%. A significant proportion of teenage pregnant mothers were in their first pregnancies. The teenage mothers were nearly three times more at risk of developing anaemia (OR = 2.83, 95% CI = 2.2-3.7, p < 0.0001) and delivering pre-term (OR = 2.97, 95% CI = 2.4-3.7, p < 0.0001). Teenage mothers were twice as likely to develop hypertensive problems in pregnancy (OR = 2.2, 95% CI = 1.5-3.2, p < 0.0001) and were more likely to deliver vaginally with no significant increase in the risk of assisted vaginal delivery or caesarean section. Young mothers were nearly twice at risk of delivering low birth weight babies (OR = 1.8, 95% CI = 1.5-2.2, p < 0.0001) and 50% less likely to have normal birth weight babies (OR = 0.5, 95% CI = 1.2-2.9, p < 0.0001). The outcome of this study showed that teenage pregnancies are still a common occurrence in rural India in spite of various legislations and government programmes and teenage pregnancy is a risk factor for poor obstetric outcome in rural India. Cultural practices, poor socioeconomic conditions, low literacy rate and lack of awareness of the risks are some of the main contributory factors. Early booking

    Abdominal pregnancy is a rare entity, which has been classified as primary or secondary by Studiford criteria. A retrospective study, between January 1989 and December 1994, realized at Instituto Nacional de Perinatología, found 35,080 pregnancies, from which 149 happened to be ectopic, and 6 of them were abdominal. All patients belonged to a low income society class, age between 24 and 35 years, and average of gestations in 2.6. Gestational age varied from 15 weeks to 32.2 weeks having only one delivery at term with satisfactory postnatal evolution. One patient had a recurrent abdominal pregnancy, with genital Tb as a conditional factor. Time of hospitalization varied from 4 to 5 days, and no further patient complications were reported. Fetal loss was estimated in 83.4%. Abdominal pregnancy is often the sequence of a tubarian ectopic pregnancy an when present, it has a very high maternal mortality reported in world literature, not found in this study. The stated frequency of abdominal pregnancy is from 1 of each 3372, up to 1 in every 10,200 deliveries, reporting in the study 1 abdominal pregnancy in 5846 deliveries. The study had two characteristic entities one, the recurrence and two, the delivery at term of one newborn. Abdominal pregnancy accounts for 4% of all ectopic pregnancies. Clinical findings in abdominal pregnancies are pain, transvaginal bleeding and amenorrea, being the cardinal signs of ectopic pregnancy.

    2016-04-01

    Pregnancy associated liver diseases affect up to 3% of pregnant women and are the most frequent cause of liver dysfunction in pregnancy. When severe, they are associated with significant morbidity and mortality for both mother and infant. A rapid evaluation to distinguish them from non-pregnancy related liver dysfunction is essential, in order to facilitate appropriate management. Liver disease unrelated to pregnancy can present de novo in pregnancy, or pregnancy can occur in women with preexisting liver pathology (Table 1). Research and subsequent advances in medical care have resulted in improved but still not satisfactory maternal and fetal outcomes. In this review we provide an overview of the liver diseases specific to the pregnant state and an update on their pathogenesis, treatment and outcomes. The risks of pregnancy in women with pre-existent liver pathology is detailed and recent advances in our understanding of specific risks and outcomes are discussed.

  2. Diabetes insipidus and pregnancy.

    PubMed

    Chanson, Philippe; Salenave, Sylvie

    2016-06-01

    Diabetes insipidus (DI) is a rare complication of pregnancy. It is usually transient, being due to increased placental production of vasopressinase that inactivates circulating vasopressin. Gestational, transient DI occurs late in pregnancy and disappears few days after delivery. Acquired central DI can also occur during pregnancy, for example in a patient with hypophysitis or neuroinfundibulitis during late pregnancy or postpartum. Finally, pre-existing central or nephrogenic DI may occasionally be unmasked by pregnancy. Treatment with dDAVP (desmopressin, Minirin(®)) is very effective on transient DI of pregnancy and also on pre-existing or acquired central DI. Contrary to vasopressin, dDAVP is not degraded by vasopressinase. Nephrogenic DI is insensitive to dDAVP and is therefore more difficult to treat during pregnancy if fluid intake needs to be restricted.

    Pruritic folliculitis of pregnancy is a rare disease of unknown etiology. It occcurs primarily during pregnancy, usually with spontaneous resolution postpartum. It is characterized by a benign dermatosis, with papular and pustular follicular lesions that first appear on the torso and occasionally spread throughout the body. We report the case of a patient in the 27th week of pregnancy, with a two-month evolution of pruritic and papular erythematous lesions on her lower back. Differential diagnosis includes other pregnancy-specific dermatoses: gestational pemphigoid, pruritic urticarial papules and plaques of pregnancy (PUPPP), prurigo of pregnancy, and (PUPPP) and prurigo of pregancy. Histopathological tests showed changes consistent with pruritic folliculitis of pregnancy. This case is relevant due to its rare nature and its clinical and histopathological characteristics.

    Fetal abnormality is more common in multiple than in singleton pregnancies. This, together with the requirement to consider the risks with at least two babies to sample correctly each fetus and to undertake accurately-targeted selective termination, amounts to a major challenge for obstetricians involved in prenatal diagnosis. Early determination of chorionicity should be routine, since this influences not only the genetic risks but also the invasive procedure chosen for karyotyping or genotyping. Assessment of nuchal translucency identifies individual fetuses at risk of trisomy. Contrary to expectation, invasive procedures in twins appear to have procedure-related miscarriage rates that are similar to those in singletons. Instead, contamination remains a concern at chorionic villus sampling. Elective late karyotyping of fetuses may have a role in some countries. Whereas management options for discordant fetal abnormality are relatively straightforward in dichorionic pregnancies, monochorionic pregnancies are at risk of co-twin sequelae after any single intrauterine death. Techniques have now been developed to occlude completely the cord vasculature by laser and/or ultrasound guided bipolar diathermy. Given the complexities associated with prenatal diagnosis, all invasive procedures in multiple pregnancies should be performed in tertiary referral centres.

    Background Recent studies suggest that placenta may harbour a unique microbiome that may have origin in maternal oral microbiome. Although the major physiological and hormonal adjustments observed in pregnant women lead to biochemical and microbiological modifications of the oral environment, very few studies evaluated the changes suffered by the oral microbiota throughout pregnancy. So, the aim of our study was to evaluate oral yeast colonization throughout pregnancy and to compare it with non-pregnant women. Material and Methods The oral yeast colonization was assessed in saliva of 30 pregnant and non-pregnant women longitudinally over a 6-months period. Demographic information was collected, a non-invasive intra-oral examination was performed and saliva flow and pH were determined. Results Pregnant and non-pregnant groups were similar regarding age and level of education. Saliva flow rate did not differ, but saliva pH was lower in pregnant than in non-pregnant women. Oral yeast prevalence was higher in pregnant than in non-pregnant women, either in the first or in the third trimester, but did not attain statistical significance. In individuals colonized with yeast, the total yeast quantification (Log10CFU/mL) increase from the 1st to the 3rd trimester in pregnant women, but not in non-pregnant women. Conclusions Pregnancy may favour oral yeast growth that may be associated with an acidic oral environment. Key words:Oral yeast, fungi, pregnancy, saliva pH. PMID:28160578

    Tests of iron and folate nutrition have been carried out in early pregnancy and at delivery in 63 Bantu females. Accepted normal values for serum iron, and percentage saturation of transferrin, but not for unsaturated iron-binding capacity, for non-pregnant subjects were found to apply equally well in pregnancy. Concomitant folate deficiency in early pregnancy did not render tests of iron deficiency less valid. The unsaturated iron-binding capacity, percentage saturation, and marrow iron stores in early pregnancy all showed a significant correlation with the haemoglobin value at term. Patients with normal marrow iron stores and a percentage saturation of transferrin of 20 or more at or before the 24th week are unlikely to become anaemic from iron deficiency during pregnancy.

    This paper has three objectives: to explore the nature of the problem implicit in the term "risk acceptability," to examine the possible contributions of scientific information to risk standard-setting, and to argue that societal response is best guided by considerations of process rather than formal methods of analysis. Most technological risks are not accepted but are imposed. There is also little reason to expect consensus among individuals on their tolerance of risk. Moreover, debates about risk levels are often at base debates over the adequacy of the institutions which manage the risks. Scientific information can contribute three broad types of analyses to risk-setting deliberations: contextual analysis, equity assessment, and public preference analysis. More effective risk-setting decisions will involve attention to the process used, particularly in regard to the requirements of procedural justice and democratic responsibility.

    2014-01-01

    Objective Pharmacotherapy for mood disorders during pregnancy is often complicated by pregnancy-related pharmacokinetic changes and the need for dose adjustments. The objectives of this review are to summarize the evidence for change in perinatal pharmacokinetics of commonly used pharmacotherapies for mood disorders, discuss the implications for clinical and therapeutic drug monitoring (TDM), and make clinical recommendations. Methods The English-language literature indexed on MEDLINE/PubMed was searched for original observational studies (controlled and uncontrolled, prospective and retrospective), case reports, and case series that evaluated or described pharmacokinetic changes or TDM during pregnancy or the postpartum period. Results Pregnancy-associated changes in absorption, distribution, metabolism, and elimination may result in lowered psychotropic drug levels and possible treatment effects, particularly in late pregnancy. Mechanisms include changes in both phase 1 hepatic cytochrome P450 and phase 2 uridine diphosphate glucuronosyltransferase enzyme activities, changes in hepatic and renal blood flow, and glomerular filtration rate. Therapeutic drug monitoring, in combination with clinical monitoring, is indicated for tricyclic antidepressants and mood stabilizers during the perinatal period. Conclusions Substantial pharmacokinetic changes can occur during pregnancy in a number of commonly used antidepressants and mood stabilizers. Dose increases may be indicated for antidepressants including citalopram, clomipramine, imipramine, fluoxetine, fluvoxamine, nortriptyline, paroxetine, and sertraline, especially late in pregnancy. Antenatal dose increases may also be needed for lithium, lamotrigine, and valproic acid because of perinatal changes in metabolism. Close clinical monitoring of perinatal mood disorders and TDM of tricyclic antidepressants and mood stabilizers are recommended. PMID:24525634

    During pregnancy, untreated sexually transmitted or urinary tract infections are associated with significant morbidity, including low birth weight, preterm birth, and spontaneous abortion. Approximately one in four women will be prescribed an antibiotic during pregnancy, accounting for nearly 80% of prescription medications in pregnant women. Antibiotic exposures during pregnancy have been associated with both short-term (e.g., congenital abnormalities) and long-term effects (e.g., changes in gut microbiome, asthma, atopic dermatitis) in the newborn. However, it is estimated that only 10% of medications have sufficient data related to safe and effective use in pregnancy. Antibiotics such as beta-lactams, vancomycin, nitrofurantoin, metronidazole, clindamycin, and fosfomycin are generally considered safe and effective in pregnancy. Fluoroquinolones and tetracyclines are generally avoided in pregnancy. Physiologic changes in pregnancy lead to an increase in glomerular filtration rate, increase in total body volume, and enhanced cardiac output. These changes may lead to pharmacokinetic alterations in antibiotics that require dose adjustment or careful monitoring and assessment.

    To examine the rates and factors associated with alcohol consumption after the recognition of pregnancy among indigenous pregnant women, as well as the rates and factors associated with continuing alcohol consumption after the recognition of pregnancy among indigenous pregnant women who drank alcohol before the recognition of pregnancy in 10 hospitals in southern and eastern Taiwan. A total of 806 indigenous women who had just given birth in 10 hospitals in southern and eastern Taiwan were recruited. They were interviewed to collect their substance use information, demographic characteristics, psychological health status, history of physical abuse, and pregnancy history. The rates of alcohol consumption after the recognition of pregnancy in all indigenous pregnant women and the rates of continuing alcohol consumption after the recognition of pregnancy among those who drank alcohol before the recognition of pregnancy were calculated. The factors relating to alcohol consumption and continuing alcohol consumption after the recognition of pregnancy were examined using logistic regression analyses. The results of this study found that 26.6% of indigenous pregnant women drank alcohol at any stage after the recognition of pregnancy, and 52.5% of indigenous pregnant women who drank alcohol before the recognition of pregnancy persisted in drinking alcohol after the recognition of pregnancy. Multiple parities, smoking or chewing betel quid after the recognition of pregnancy, and a higher frequency of drinking alcohol before the recognition of pregnancy were significantly associated with alcohol consumption and continuing alcohol consumption after the recognition of pregnancy. Meanwhile, being single or divorced, and intimate partner violence after the recognition of pregnancy were significantly associated with alcohol consumption after the recognition of pregnancy.

    The impact of an ectopic pregnancy in the next generation is unknown. Our aim was to compare reproductive outcomes in daughters of women with and without ectopic pregnancy. Designed as a historical prospective controlled cohort study with data collected in four Danish registries from 1977-2009, women with ectopic pregnancy during 1977-1982 were age-matched to women without ectopic pregnancy. Daughters of these two cohorts were followed until 2009. We compared 5126 daughters of women with ectopic pregnancy with 19 928 daughters of women without ectopic pregnancy. The daughters of women with ectopic pregnancy had a 1.5-fold (95% confidence interval 1.2-1.9) increased risk of ectopic pregnancy, while for deliveries this was 1.0 (1.0-1.1), for miscarriages 1.1 (1.0-1.2), and for induced abortions 1.3 (1.2-1.4). Daughters of mothers with ectopic pregnancy have a 50% higher risk of ectopic pregnancy than daughters of women without an ectopic pregnancy, but a normal delivery rate.

  17. Anticoagulant prophylaxis for placenta mediated pregnancy complications.

    2011-02-01

    Thrombophilias are not yet established as a cause of the placenta-mediated pregnancy complications (pregnancy loss, pre-eclampsia, small for gestational age and placental abruption). A thrombophilia may be only one of many factors that lead to development of these complications. Our recent large systematic review of prospective cohort studies highlight that the association between thrombophilia and placenta mediated pregnancy complications is far from proven. The small step of previously describing an association in case control studies has led a large number of clinicians and opinion leaders to take the large leap of accepting this relationship as being causal and potentially treatable with anticoagulant interventions. Furthermore, while data in women with prior severe pre-eclpamsia, abruption and small for gestational age births without thrombophilia suggests some promise for anticoagulant prophylaxis to prevent complications in subsequent pregnancies in these women, in the absence of large well done and generalisable "no intervention" controlled studies adopting anticoagulant prophylaxis to prevent these complications is premature. The absence of strong evidence, coupled with the small potential for harm from anticoagulant prophylaxis suggests that these drugs should be considered experimental in thrombophilic and non-thrombophilic women with prior placenta mediated pregnancy complications.

  18. Thyroid in pregnancy: From physiology to screening.

    Thyroid hormones are crucial for the growth and maturation of many target tissues, especially the brain and skeleton. During critical periods in the first trimester of pregnancy, maternal thyroxine is essential for fetal development as it supplies thyroid hormone-dependent tissues. The ontogeny of mature thyroid function involves organogenesis, and maturation of the hypothalamus, pituitary and the thyroid gland; and it is almost complete by the 12th-14th gestational week. In case of maternal hypothyroidism, substitution with levothyroxine must be started in early pregnancy. After the 14th gestational week, fetal brain development may already be irreversibly affected by lack of thyroid hormones. The prevalence of manifest hypothyroidism in pregnancy is about 0.3-0.5%. The prevalence of subclinical hypothyroidism varies between 4 and 17%, strongly depending on the definition of the upper TSH cutoff limit. Hyperthyroidism occurs in 0.1-1% of all pregnancies. Positivity for antibodies against thyroid peroxidase (TPOAb) is common in women of childbearing age with an incidence rate of 5.1-12.4%. TPOAb-positivity may be regarded as a manifestation of a general autoimmune state which may alter the fertilization and implantation processes or cause early missed abortions. Women positive for TPOAb are at a significant risk of developing hypothyroidism during pregnancy and postpartum. Laboratory diagnosis of thyroid dysfunction during pregnancy is based upon serum TSH concentration. TSH in pregnancy is physiologically lower than the non-pregnant population. Results of multiple international studies point toward creation of trimester-specific reference intervals for TSH in pregnancy. Screening for hypothyroidism in pregnancy is controversial and its implementation varies from country to country. Currently, the case-finding approach of screening high-risk women is preferred in most countries to universal screening. However, numerous studies have shown that one-third to one

    Maternal immunization holds tremendous promise to improve maternal and neonatal health for a number of infectious conditions. The unique susceptibilities of pregnant women to infectious conditions, as well as the ability of maternally-derived antibody to offer vital neonatal protection (via placental transfer), together have produced the recent increased attention on maternal immunization. The Advisory Committee on Immunization Practices (ACIP) currently recommends 2 immunizations for all pregnant women lacking contraindication, inactivated Influenza and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap). Given ongoing research the number of vaccines recommended during pregnancy is likely to increase. Thus, achieving high vaccination coverage of pregnant women for all recommended immunizations is a key public health enterprise. This review will focus on the present state of vaccine acceptance in pregnancy, with attention to currently identified barriers and determinants of vaccine acceptance. Additionally, opportunities for improvement will be considered.

    Background Diabetes in pregnancy has been associated with a paradoxically reduced risk of neonatal death in twin pregnancies. Risk “shift” may be a concern in that the reduction in neonatal deaths may be due to an increase in fetal deaths (stillbirths). This study aimed to clarify the impact of diabetes on the risk of perinatal death (neonatal death plus stillbirth) in twin pregnancies. Methods This was a retrospective cohort study of twin births using the largest available dataset on twin births (the U.S. matched multiple birth data 1995-2000; 19,676 neonates from diabetic pregnancies, 541,481 from non-diabetic pregnancies). Cox proportional hazard models were applied to estimate the adjusted hazard ratios (aHR) of perinatal death accounting for twin cluster-level dependence. Results Comparing diabetic versus non-diabetic twin pregnancies, overall perinatal mortality rate was counterintuitively lower [2.1% versus 3.3%, aHR 0.70 (95% confidence intervals 0.63-0.78)]. Individually, both stillbirth and neonatal mortality rates were lower in diabetic pregnancies, but we identified significant differences by gestational age and birth weight. Diabetes was associated with a survival benefit in pregnancies completed before 32 weeks [aHR 0.55 (0.48-0.63)] or with birth weight <1500 g [aHR 0.61 (0.53-0.69)]. In contrast, diabetes was associated with an elevated risk of perinatal death in pregnancies delivered between 32 and 36 weeks [aHR 1.38 (1.10-1.72)] or with birth weight >=2500 g [aHR 2.20 (1.55-3.13)]. Conclusions Diabetes in pregnancy appears to be “protective” against perinatal death in twin pregnancies ending in very preterm or very low birth weight births. Prospective studies are required to clarify whether these patterns of risk are real, or they are artifacts of unmeasured confounders. Additional data correlating these outcomes with the types of diabetes in pregnancy are also needed to distinguish the effects of pre-gestational vs. gestational diabetes

    Cancer diagnosed during pregnancy is uncommon, complicating between 0.02% and 0.1% of all pregnancies. Nonetheless, due to increasing age of childbearing, the incidence of cancer during pregnancy is likely to increase due to higher incidence of several age-dependent malignancies. The most common malignancies include breast cancer, cervical cancer, malignant melanoma and lymphoma. One of the key challenges in the management of cancer in pregnancy is treating the women with standard chemotherapy regimen, without compromising the safety of the developing foetus. Exposure of chemotherapy in the first trimester is associated with an increased risk of major birth defects, whereas use in the second and third trimesters is associated with intrauterine growth restriction, low birthweight and stillbirth. In this article, we review available data regarding the use of chemotherapeutic agents in pregnancy, and we summarise the neonatal outcomes, including malformations, perinatal complications and long-term follow-up. In addition, the management plan during pregnancy is also discussed.

    2013-08-01

    Abnormalities of liver function (notably rise in alkaline phosphatase and fall in serum albumin) are common in normal pregnancy, whereas rise in serum bilirubin and aminotransferase suggest either exacerbation of underlying pre-existing liver disease, liver disease related to pregnancy or liver disease unrelated to pregnancy. Pregnant women appear to have a worse outcome when infected with Hepatitis E virus. Liver diseases associated with pregnancy include abnormalities associated hyperemesis gravidarum, acute fatty liver disease, pre-eclampsia, cholestasis of pregnancy and HELLP syndrome. Prompt investigation and diagnosis is important in ensuring a successful maternal and foetal outcome. In general, prompt delivery is the treatment of choice for acute fatty liver, pre-eclampsia and HELLP syndrome and ursodeoxycholic acid is used for cholestasis of pregnancy although it is not licenced for this indication.

    The objective of the study was to assess the frequency of alternative medical usage in an antenatal population. A survey of alternative medicine usage was carried out among 305 consecutive patients over 2 months at their registration in mid-pregnancy at an Australian Antenatal Clinic. The study showed that something like 40% of patients used alternative medical therapy, including 12% herbal therapy. No specific study of pregnancy outcome was carried out, but it is of concern that some herbs taken had the potential to adversely affect pregnancy outcome. The herbal therapies commonly used in pregnancy are reviewed with their potential complications; examples of toxicity are also discussed. It is important to obtain a herbal medicine history at any time but particularly in pregnancy. Herbs may have unrecognised effects on pregnancy or labour, have interactions with prescribed medications and have potentially serious complications for the foetus.

    Adolescent pregnancy remains a public health issue with significant medical, emotional, and societal consequences for the adolescent mother, her child, and her family. Teenage pregnancies are at higher risk of many adverse outcomes, including preterm delivery, low birth weight, and neonatal and infant mortality. Teen pregnancy and motherhood may have detrimental effects on the teen mother and her child; antenatal and postpartum care need to be adapted to meet the special needs of pregnant adolescents because standard obstetrical environments may not do so. This comprehensive review of adolescent pregnancy will highlight global statistics, factors contributing to adolescent pregnancy, social implications of adolescent pregnancy, obstetrical and neonatal outcomes, and the importance of multidisciplinary antenatal and postnatal care.

    Pregnancy causes significant changes in all systems of the body. Although most of them are physiological, they may also lead to pathological consequences. The resulting pathological changes may occur for the first time or existing diseases affected by pregnancy can become more serious or change course. Diseases specific only to pregnancy may arise. Like all systems of the body, the visual system is also affected by pregnancy, developing a wide range of physiological and pathological changes. Knowing the ocular physiological changes and diagnosing eye diseases that may develop during pregnancy, and preventing and treating these diseases is crucial to ensure the baby’s healthy development. Therefore, we have reviewed the conditions that an ophthalmologist should recognize, follow-up, and pay attention to during treatment and summarized them under the topic “pregnancy and the eye”.

    A project about attitudes and practices related to pregnancy and birth was presented by a team of doctors at the Gustavo Baz Hospital in the Municipality of Tlalnepantla and at the National Institute of Perinatology, both in Mexico. The objective of this study was to describe the concepts, the attitudes, and the practices concerning the reproductive process that women and their partners have, in order to use them as a basis for the elaboration of an educational program about reproduction, which will be applied at government Health Centers. 100 pregnant women attending these Health Centers, 1st level, Out-Patient, 2nd level, were selected; all these women had requested prenatal care. A questionaire was used, previously pilot tested, which consisted of 32 questions grouped in 7 areas; 1) General characteristics, 2) Background factors, 3) Reaction when pregnancy was known, 4) Participation of the male partner, 5) Preparation for the newborn, 6) Prenatal Control, and 7) Education about reproduction. The results showed a lack or little planning about the pregnancy preparation for the newborn, limited participation of the male partner, prenatal control initiated with more frequency in the 1st trimester of the pregnancy and a desire to receive information, principally about child care. 2 principal benefits will be derived from modifying the traditional behaviors that intervene in the health and reproduction of the couples studied: Greater responsibility and a positive attitude toward pregnancy, childbirth, puerperium, and child care on the part of the mother and her partner. A high rate of compliance in adhering to instructions from the team of health professionals, acceptance of therapeutic indications, and knowledge on the part of mother and partner will benefit the health of the mother and child diad.

    We present two cases of ectopic pregnancy located within the remnant tube following ipsilateral salpingectomy. This particular pathology is rare and yet has significant consequences for the patient, with mortality rates 10–15 times higher than other ectopic pregnancies. It demonstrates that salpingectomy does not exclude ectopic pregnancy on the ipsilateral side. We suggest careful clinical consideration and bring attention to the current surgical technique.

    QUESTION: A 27-year-old patient in our clinic with familial Mediterranean fever (FMF) has been treated with colchicine for the last decade. She is planning her first pregnancy. What recommendations should we give her regarding use of colchicine before and during pregnancy, bearing in mind that discontinuation of colchicine could lead to complications from amyloidosis? ANSWER: Colchicine passes through the placenta in humans, is teratogenic in animals, and raises rates of male and female infertility. Based on several patients with chromosomal anomalies, some authorities recommend that patients who require colchicine therapy during pregnancy undergo amniocentesis with karyotyping. In contrast, an increasing body of evidence suggests that colchicine use throughout pregnancy carries no substantial teratogenic or mutagenic risk when used at recommended doses. Its use prevents febrile attacks of FMF and reduces the frequency of renal complications. PMID:12943352

    Antiphospholipid syndrome (APS) is the association of antiphospholipid antibodies with thromboses and/or obstetric morbidity. Obstetric morbidity includes recurrent first trimester loss, stillbirth, intrauterine death, preeclam-psia, premature birth and fetal growth restriction. Although current treatment regimens including aspirin and low-molecular weight heparin have improved pregnancy outcomes, 30% of affected women have pregnancy complica-tions. Women with APS are therefore high-risk pregnancies who should be monitored in specialist centres according to international standards.

    Hypertension is present in about 10 % of all pregnancies. The frequency of chronic hypertension and that of gestational hypertension is increasing. The management of pregnant women with hypertension remains a significant, but controversial, public health problem. Although treatment of hypertension in pregnancy has shown to reduce maternal target organ damage, considerable debate remains concerning treatment. We review current evidence regarding treatment goals, the ideal treatment starting time, and which drugs are available for the treatment of hypertension in pregnancy.

    Women with renal disease who conceive and continue a pregnancy are at significant risk for adverse maternal and fetal outcomes. Risk is inversely related to the degree of renal insufficiency. Pregnancy-induced changes in the urinary tract can temporarily increase renal function compromise, such as nephrosis, but most often results in no net increase in dysfunction. Common complications of pregnancy--such as hypertension and hypovolemia--can be associated with acute renal injury or aggravation of pre-existing disease.

    ABSTRACT OBJECTIVE To determine the knowledge, counseling practices, and learning needs of practitioners in British Columbia regarding risk factors for listeriosis in pregnancy. DESIGN A 1-page, mailed, self-administered, anonymous questionnaire. SETTING British Columbia. PARTICIPANTS A total of 827 practitioners (614 family physicians, 93 midwives, and 120 family practice residents) were sent the questionnaire. MAIN OUTCOME MEASURES Awareness of listeriosis, knowledge of the risk factors for listeriosis, practices for counseling pregnant women, practitioners’ learning needs, and provider and practice characteristics. RESULTS A total of 340 practitioners (41%) completed the questionnaire. While most (88%) physicians and midwives had heard of listeriosis, few (18%) were aware that infection was more common during pregnancy. One-third (33%) of practitioners counseled pregnant women about the risk factors for listeriosis. The main reasons for not providing such counseling were lack of knowledge and the perception that listeriosis was rare and not an important concern for pregnant women. Rates of counseling were highest among midwives (84%) and lowest among physicians practising outside the Lower Mainland of British Columbia (12%). Of those practitioners providing prenatal care, 47% counseled pregnant women about the risks of unpasteurized milk and 41% counseled women about the risks of consuming soft cheese; few counseled about the risks of consuming deli meat or raw hot dogs (25%), unwashed fruit and vegetables (12%), or refrigerated smoked seafood (6%). CONCLUSION Most prenatal care providers in British Columbia are unaware of the risk factors for listeriosis or its propensity for pregnant women and do not counsel their pregnant patients about these risks.

    In order to detect neutrons and protons in the 50 to 600 MeV energy range and measure their polarization, an efficient, low-noise, self-calibrating device is being designed. This detector, known as the High Acceptance Recoil Polarimeter (HARP), is based on the recoil principle of proton detection from np[r arrow]n[prime]p[prime] or pp[r arrow]p[prime]p[prime] scattering (detected particles are underlined) which intrinsically yields polarization information on the incoming particle. HARP will be commissioned to carry out experiments in 1994.

    The baby's crying is his most important mean of communication. The crying monitoring performed by devices that have been developed doesn't ensure the complete safety of the child. It is necessary to join, to these technological resources, means of communicating the results to the responsible, which would involve the digital processing of information available from crying. The survey carried out, enabled to understand the level of adoption, in the continental territory of Portugal, of a technology that will be able to do such a digital processing. It was used the TAM as the theoretical referential. The statistical analysis showed that there is a good probability of acceptance of such a system.

    The hypothalamic-pituitary-adrenal axis is central to mammalian reproductive function, including conception, pregnancy maintenance, parturition, and breastfeeding. Pregnancy is associated with substantial physiologic changes within this endocrine axis to meet the demands of pregnancy, which include support of the fetus (volume support, nutritional and oxygen supply, clearance of fetal waste), protection of the fetus (from starvation, drugs, toxins), preparation of the uterus for labor, and protection of the mother from potential cardiovascular injury at delivery. This article reviews the anatomy, embryology, and physiology of the pituitary. The effect of pregnancy on pituitary structure and function, in health and disease, also is discussed.

    Increasing evidence indicates that hypertension in pregnancy is an under recognized risk factor for cardiovascular disease (CVD). Compared with women who have had normotensive pregnancies, those who are hypertensive during pregnancy are at greater risk of cardiovascular and cerebrovascular events and have a less favorable overall risk profile for CVD years after the affected pregnancies. One factor that might underlie this relationship is that hypertensive disorders of pregnancy (pre-eclampsia, in particular) and CVD share several common risk factors (e.g. obesity, diabetes mellitus and renal disease). Alternatively, hypertension in pregnancy could induce long-term metabolic and vascular abnormalities that might increase the overall risk of CVD later in life. In both cases, evidence regarding risk-reduction interventions specific to women who have had hypertensive pregnancies is lacking. While awaiting results of large-scale studies, hypertensive disorders of pregnancy should be screened for during assessment of a woman's overall risk profile for CVD. Women at high risk must be monitored closely for conventional risk factors that are common to both CVD and hypertensive disorders of pregnancy and treated according to current evidence-based national guidelines.

    Association of hyperthyroidism and pregnancy is not an unusual event, and has an impact on both the mother and fetus. After delivery, it may also affect the newborn and the nursing mother. Clinical management of this situation is quite different from that required by non-pregnant hyperthyroid women and poses significant diagnostic and therapeutic challenges. This review addresses aspects related to the unique characteristics of biochemical assessment of thyroid function in pregnancy, the potential causes of hyperthyroidism in pregnancy, and the clinical and therapeutic approach in each case. Special attention is paid to pregnancy complicated with Graves' disease and its different the maternal, fetal, neonatal, and postnatal consequences.

We initially begin by describing the application of common clinical estimators of GFR and proteinuria in pregnancy and then summarize recent studies regarding pregnancy in women with chronic kidney disease and the latest information on the use of common renal medications in pregnancy. In the final section, we describe advances in our understanding of the pathophysiology of preeclampsia and the potential clinical implications of these discoveries for screening, prevention, and treatment of preeclampsia.

    The management of lupus nephritis in pregnancy presents a diagnostic and therapeutic challenge for providers. Pregnancy creates a series of physiologic changes in the immune system and kidney that may result in an increased risk of disease flare and adverse maternal and fetal outcomes, such as preeclampsia, fetal loss, and preterm delivery. Conception should be delayed until disease is in remission to ensure the best pregnancy outcomes. Maternal disease activity and fetal well-being should be monitored closely by an interdisciplinary team, including obstetricians, rheumatologists, and nephrologists throughout pregnancy. Careful attention must be paid to the dosing and potential teratogenicity of medications.

    Liver disease can be observed in pregnant women whether or not related to pregnancy. Liver disorders can be revealed by pruritus, vomiting, jaundice or abnormal liver blood tests during pregnancy. These liver manifestations can lead to the diagnosis of liver disease specifically associated to pregnancy as intrahepatic pregnancy, intrahepatic cholestasis of pregnancy, Hyperemesis gravidarum, acute fatty liver of pregnancy and preeclampsia-induced liver injury. Pregnancy may also be a risk factor for other liver diseases coincident with pregnancy as viral hepatitis, thrombosis, drug toxicity or gallstone. Finally, pre-existing liver disease must be taken into account given the risk of fœto-maternal transmission risk as well as the risk of decompensation of underlying cirrhosis secondary to the hemodynamic changes caused by pregnancy. The aim of this revue is to perform an update on the various situations that can be observed, the principles of management of these liver diseases, in order to reduce the risk of complications and to ensure the best maternal and fetal prognosis.

    In recent decades, the association between a hypercoagulable state and its causes and adverse pregnancy outcome, in particular recurrent pregnancy loss (RPL) has been studied extensively. Although the first studies were focused only on the association between thrombophilia and RPL, subsequent studies underlined also a potential role of antithrombotic treatment to prevent vascular complication such as venous thromboembolism (VTE) during pregnancy. Thromboprophylaxis should be considered also for pregnant subjects carriers of molecular thrombophilia or that previously experienced VTE, in order to prevent VTE during pregnancy, while antithrombotic treatment for VTE should be performed during all pregnant periods.

    Anatomic and physiologic adaptations within the renal system during pregnancy are significant. Alterations are seen in renal blood flow and glomerular filtration, resulting in changes in normal renal laboratory values. When these normal renal adaptations are coupled with pregnancy-induced complications or preexisting renal dysfunction, the woman may demonstrate a reduction of renal function leading to an increased risk of perinatal morbidity and mortality. This article will review normal pregnancy adaptations of the renal system and discuss common pregnancy-related renal complications.

    The aim of this study was to understand the meanings of acceptance attributed to pregnancy and their influence on the eating behavior of pregnant women attending a health unit located in a low-income neighborhood in the city of Rio de Janeiro, Brazil. The methodology involved a qualitative approach with social representations as the analytical category. Data were collected through semi-structured interviews with adolescent and adult pregnant women (primiparous or multiparous) in different stages of pregnancy. Discourse analysis drew on in-depth hermeneutics, using thematic analysis as the main technical resource. Two representational categories emerged from the set of discourses, namely accepting versus not accepting the pregnancy, which involved different eating behaviors. In the former, women tended to either eat adequately or overeat. For the latter, not accepting the pregnancy was associated with denial of eating, temporarily or throughout the pregnancy.

    Molar pregnancy remains an uncommon and still not fully understood disorder. The clinical presentation has changed over recent decades. In developed countries complete moles are now usually diagnosed early (on clinical and/or ultrasound scan criteria) so that the more severe clinical presentations are much less commonly seen. The important differences between complete and partial moles and their risk factors are now well recognized. Common protocols for managing persistent gestational trophoblastic disease are being derived, and molecular genetic studies are advancing our understanding of molar pregnancy and its sequelae. Cure rates approaching 100% should now be the rule rather than the exception. There is a strong case for formal registration and monitoring of all cases through specialist centers.

    Hypertension-related maternal mortality reaches 16% when it is compared to other causes of maternal mortality such as sepsis, bleeding or abortus. Pregnant women with hypertension disorder are at increased risk for experiencing numerous complications including disseminated intravascular coagulation (DIC), cerebral hemorrhage, liver dysfunction and acute renal failure; while to the fetus, it may cause intrauterine growth retardation, prematurity and perinatal mortality. Hypertension in pregnancy should be managed appropriately to reduce maternal and fetal morbidity and mortality rate, i.e. by preventing women from getting the risks of increased blood pressure, preventing disease progression and preventing the development of seizure and considering termination of pregnancy in life-threatening situation for maternal and fetal health.

    Acute fatty liver of pregnancy (AFLP) is rare and is peculiar to the latter half of pregnancy. Despite the high rates of death among affected mothers and their fetuses, early recognition of the disease and immediate delivery of the infant may improve the chances of survival. This paper describes a case of AFLP, characterized by a rapid decrease in the size of the liver, a greatly prolonged prothrombin time and minimal increases in the serum transaminase levels, in which an immediate cesarean section followed by vigorous supportive care led to survival of both mother and infant. It is clear that guidelines on treatment are necessary if the management of such cases is to be successful. Images FIG. 2 PMID:6751513

    2013-05-01

    The National Toxicology Program (NTP) Office of Health Assessment and Translation (OHAT) conducted an evaluation of the developmental effects and pregnancy outcomes associated with cancer chemotherapy use during pregnancy in humans. The final NTP monograph was completed in May 2013 (available at http:// ntp.niehs.nih.gov/go/36495). The incidence of cancer during pregnancy has been reported to occur from 17 to 100 per 100,000 pregnant women. Chemotherapy is a common treatment for cancer; however, most chemotherapy agents are classified as known or suspected human teratogens. Cancer chemotherapy use during pregnancy was selected for evaluation by the NTP because of the: (1) paucity of comprehensive reviews on the pregnancy outcomes following cancer chemotherapy use during pregnancy in humans, including the integration of the developmental animal toxicology literature with the observational studies in humans, and (2) growing public interest in the developmental effects of chemotherapy on offspring exposed to cancer chemotherapy during gestation due to the expected incidence of cancer diagnosed during pregnancy as women delay pregnancy to later ages. Of the approximately 110 cancer chemotherapeutic agents currently in use, the NTP monograph includes data on 56 agents used during 1,261 pregnancies for which pregnancy outcomes were documented. Overall, the NTP evaluation found that treatment with chemotherapy for cancer appeared to be associated with: (1) a higher rate of major malformations following exposure during the first trimester compared to exposure in the second and/or third trimester; (2) an increase the rate of stillbirth following exposure in the second and/ or third trimester; abnormally low levels of amniotic fluid (primarily attributable to Trastuzumab); and (3), also data are insufficient, impaired fetal growth and myelosuppression. Treatment with chemotherapy for cancer during pregnancy did not appear to increase spontaneous preterm birth, or impair

    Objective: Pregnancy brings about significant changes in respiratory function, as evidenced by alterations in lung volumes and capacities, which are attributable to the mechanical impediment caused by the growing foetus. This study was undertaken in order to identify changes in respiratory function during normal pregnancy and to determine whether such changes are more pronounced in twin pregnancy than in singleton pregnancy. Methods: Respiratory function was assessed in 50 women with twin pregnancies and in 50 women with singleton pregnancies (during the third trimester in both groups), as well as in 50 non-pregnant women. We measured the following pulmonary function test parameters: FVC; FEV1; PEF rate; FEV1/FVC ratio; FEF25-75%; and maximal voluntary ventilation. Results: All respiratory parameters except the FEV1/FVC ratio were found to be lower in the pregnant women than in the non-pregnant women. We found no significant differences between women with twin pregnancies and those with singleton pregnancies, in terms of respiratory function. Conclusions: Despite its higher physiological demands, twin pregnancy does not appear to impair respiratory function to any greater degree than does singleton pregnancy. PMID:25029647

    2016-06-01

    Hypertension (HT) is a complication of 8% of all pregnancies and 10% of HT cases are due to primary aldosteronism (PA). There is very little data on PA and pregnancy. Given the changes in the renin angiotensin system during pregnancy, the diagnosis of PA is difficult to establish during gestation. It may be suspected in hypertensive patients with hypokalemia. A comprehensive literature review identified reports covering 40 pregnancies in patients suffering from PA. Analysis of these cases shows them to be high-risk pregnancies leading to maternal and fetal complications. Pregnancy must be programmed, and if the patient has a unilateral form of PA, adrenalectomy should be performed prior to conception. It is customary to stop spironolactone prior to conception and introduce antihypertensive drugs that present no risk of teratogenicity. When conventional antihypertensive drugs used during pregnancy fail to control high blood pressure, diuretics, including potassium-sparing diuretics may be prescribed. Adrenalectomy can be considered during the second trimester of pregnancy exclusively in cases of refractory hypertension. A European retrospective study is currently underway to collect a larger number of cases.

    2014-09-01

    Hyperprolactinemia, frequently caused by a prolactinoma, is an important cause of infertility among young women. Dopamine agonists (DA) are the treatment of choice. Although cabergoline (CAB) is currently considered the gold standard DA, bromocriptine (BRC) remains the drug of choice for women desiring pregnancy, as it was proven to be safe in more than 6,000 pregnancies. The purpose of this review is to perform a critical evaluation of CAB safety in pregnancy, as it is used by most patients harboring prolactinomas. Although the number of CAB-induced pregnancies (about 800) is still reduced as compared with those under BRC treatment, data in the literature do not point to increase risk of preterm delivery or fetal malformations, comparing to pregnancies induced by BRC and those in the general population. Moreover, CAB use throughout pregnancy was reported in about ten cases, without evidence of any harm to fetal development. Therefore, even though BRC still remains the recommended DA drug for pregnancy induction or use during pregnancy in women with prolactinomas, increasing evidences point to the safety of CAB for this purpose.

  1. Immunology of neuromyelitis optica during pregnancy

    2016-01-01

    Anti–aquaporin-4 (AQP4) autoantibody plays a key role in the pathogenesis of neuromyelitis optica (NMO). Studies have shown increased relapse rates in patients with NMO during pregnancy and postpartum. High estrogen levels during pregnancy can increase activation-induced cytidine deaminase expression, which is responsible for immunoglobulin production. Additionally, sex hormones may influence antibody glycosylation, with effects on antibody function. Estrogen decreases apoptosis of self-reactive B cells, through upregulation of antiapoptotic molecules. Furthermore, high estrogen levels during pregnancy can boost B-cell activating factor and type 1 interferon (IFN) production, facilitating development of self-reactive peripheral B cells in association with increased disease activity. Elevated levels of estrogen during pregnancy decrease IFN-γ generation, which causes a shift toward T helper (Th) 2 immunity, thereby propagating NMO pathogenesis. Women with NMO have an elevated rate of pregnancy complications including miscarriage and preeclampsia, which are associated with increased Th17 cells and reduction of T-regulatory cells. These in turn can enhance inflammation in NMO. Increased regulatory natural killer cells (CD56−) during pregnancy can enhance Th2-mediated immunity, thereby increasing inflammation. In the placenta, trophoblasts express AQP4 antigen and are exposed to maternal blood containing anti-AQP4 antibodies. Animal models have shown that anti-AQP4 antibodies can bind to AQP4 antigen in placenta leading to complement deposition and placental necrosis. Reduction of regulatory complements has been associated with placental insufficiency, and it is unclear whether these are altered in NMO. Further studies are required to elucidate the specific mechanisms of disease worsening, as well as the increased rate of complications during pregnancy in women with NMO. PMID:27761482

  2. A review of interventions to prevent pregnancy.

    Of more developed nations, the US is unique in its problem with high rates of teen pregnancy. At the heart of our failure to check teen pregnancy may lie the country's poor sexual climate, a lack of government commitment, poor health system performance, local barriers to the provision of quality sex education, and/or lack of access to contraception. Potential solutions to reduce teen pregnancy are equally wide-ranging. Programs may aim to provide better and more health and sex education, improve decision making skills, improve access to contraception and abortion, improve life opportunities as alternatives to pregnancies, restructure welfare, and/or encourage youths to refrain from premarital sex. This essay presents and discusses major prevention efforts which seem to have the highest probability of reducing pregnancy rates, and especially childbearing rates among young, unmarried teens. Literature on program successes, agency reports, and program observations are reviewed, and include programs of sex education and skills enhancement, those helping sexually active youths become better contraceptors, and those which offer life option alternatives. In the area of improving access to contraception, school-based clinics, condom distribution, and other male-oriented programs are covered. Major social structural change is, however, called for with a view to promoting equity in education, housing, and jobs. Short of such change, interventions may target school-based populations, as well as community centers to reach dropouts. Early intervention and collaboration to bolster health, social, and recreational services for children and adolescents is urged.

    Objectives: We would like to determine the best treatment option depending of ectopic pregnancy situation. Methods. This is a retrospective cohort study that registered all women admitted in Obstetrics and Gynecologic “Queen Geraldine” Hospital June 2003 until 2008 dicember. There were admitted 228 women diagnosed with Ectopic Pregnancy that were treated in our Hospital. Results: Unruptured ectopic pregnancy is diagnosed in 5,2 week of pregnancy and ruptured ectopic in an average of 6,4 weeks. Surgical intervention is registered in 170 patients and we did tubectomy. Success rate of Methotrexate application was more successful if β-hCG level was lower. If the β-hCG level is higher over 10 000 the success rate will decrease in 83 % and in β-hCG levels over 15 000 the success rate will be until 50%. Conclusions: The treatment will be determined by combination of clinical symptoms, ultrasound examination and β-hCG levels. MTX is recommended for all women without hemodinamic problems, unruptured pregnancy and low β-hCG level (β-hCG < 5000 mlU/mL). It is confirmed that the reduction of 15% of β-hCG in the fourth day after application of MTX is a success guide. PMID:22439058

    We have previously shown that expression of oestrus significantly influences the time of ovulation and pregnancy rates to timed-AI (P/TAI) in beef cattle synchronized with progesterone devices and oestradiol (Bó et al. 2016 Theriogenology 86, 388-396). Furthermore, delaying TAI from 48h to 54-58h after device removal improved P/TAI of those animals not showing oestrus by 48h. The objective of the present study was to determine whether the administration of GnRH to those animals not showing oestrus by 48h after device removal had an impact on P/TAI. Non-lactating and suckled beef cows and heifers (Bonsmara, Brangus, and Braford; n=868), with a corpus luteum (CL) or a follicle ≥8mm in diameter detected by ultrasonography (Mindray DP 30 Vet, 7.5MHz, China) and body condition score 2 to 4 (1 to 5 scale) were synchronized in 3 replicates. On Day 0, animals received a progesterone device (DIB 0.5g, Zoetis, Argentina) and 2mg of oestradiol benzoate (Von Franken, Argentina). On Day 8, DIB were removed and cows received 0.150mg of D+cloprostenol (Río de Janeiro, Argentina) plus 0.5mg oestradiol cypionate (Cipiosyn, Zoetis). In addition, all cows were tail-painted on the sacrococcygeal area (CeloTest, Biotay, Argentina) at DIB removal and were observed to determine the expression of oestrus, according to the percentage of paint loss (PL) 48h later. The animals that showed oestrus (PL>30%) were recorded and TAI at that time while those with PL ≤ 30% (not in oestrus) were randomly allocated to receive 100μg of gonadorelin (GnRH; Gonasyn, Zoetis) or no treatment and TAI between 54 to 58h after DIB removal. Pregnancy was diagnosed by ultrasonography at 45 days after TAI, and data were analysed by logistic regression. There were no significant differences among replicates, inseminators, semen source or animal class (dry cows, suckled cows or heifers; P>0.11). However, animals showing oestrus by 48h after DIB removal had higher P/TAI (371/666; 55.7; P<0.04) than those that

    Abdominal pregnancies constitute 1% of ectopic pregnancies, among which broad ligament pregnancy is a rare form. The maternal mortality rate has been reported to be as high as 20%. The diagnosis is seldom established before surgery. Laparoscopic management of broad ligament ectopic pregnancy is the ideal form of treatment in appropriately selected patients. We present the case report of successful laparoscopic treatment of a 3x3.5cm broad ligament pregnancy. A search of literature shows that ours is the 6th case report of such a rare ectopic pregnancy managed endoscopically successfully. PMID:27630914

    We describe cervical pregnancy concept and its rareness. Its frequency is one in 2,550 to 98,000 intrauterine pregnancies. Predisposing factors are related with endometrial damage due to uterine curettages and previous cesarian section. Clinical picture was nonspecific and diagnosis was based in endovaginal ultrasonography. It can cause massive bleeding and put life in risk. During 2007 we attend 829 intrauterine pregnancies at Hospital San José de Querétaro: 11 tubal, and 3 cervical, this represents an extraordinarily high frequency of cervical pregnancy. Here we report three cases of cervical pregnancies treated with total hysterectomy, two as urgency and one elective. We remark early diagnosis importance to perform conservative treatment and maintain reproductive function.

  7. Diabetic nephropathy and pregnancy.

    PubMed

    Landon, Mark B

    2007-12-01

    Diabetic nephropathy, the most common etiology for end-stage renal disease, complicates approximately 5% of insulin-dependent diabetic pregnancies. Assessment for vasculopathy is important before pregnancy because nephropathy can increase perinatal risks including potential for preeclampsia and preterm birth. Counseling women receiving renoprotective medications including angiotensin converting enzyme inhibitors has recently become complicated in light of new information suggesting a teratogenic risk for these agents. Most reproductive age women with overt diabetic nephropathy have preserved renal function and do not seem to have the progression of their disease affected by pregnancy. Perinatal outcomes are excellent for these women who have received care in tertiary institutions. However, there are relatively few women with significant renal impairment included in case series of pregnancies complicated by diabetic nephropathy. For these women, adverse perinatal outcomes are more common, and the effect of pregnancy on the course of their disease is less certain.

  8. Hypertension in pregnancy.

    PubMed

    Vest, Amanda R; Cho, Leslie S

    2014-03-01

    Hypertensive disorders of pregnancy represent the second commonest cause of direct maternal death and complicate an estimated 5-10 % of pregnancies. Classification systems aim to separate hypertension similar to that seen outside pregnancy (chronic and gestational hypertension) from the potentially fatal pregnancy-specific conditions. Preeclampsia, HELLP syndrome, and eclampsia represent increasing severities of this disease spectrum. The American College of Obstetricians and Gynecologists' 2013 guidelines no longer require proteinuria as a diagnostic criterion, because of its variable appearance in the disease spectrum. The cause involves inadequate cytotrophoblastic invasion of the myometrium, resulting in placental hypoperfusion and diffuse maternal endothelial dysfunction. Changes in angiogenic and antiangiogentic peptide profiles precede the onset of clinical preeclampsia. Women with preeclampsia should be closely monitored and receive magnesium sulfate intravenously if severe features, HELLP syndrome, or eclampsia occur. Definitive therapy is delivery of the fetus. Hypertension in pregnancy increases future maternal risk of hypertension and cardiovascular disorders.

  9. Primary aldosteronism and pregnancy.

    PubMed

    2015-10-01

    Primary aldosteronism is the most common cause of secondary hypertension. Less than 50 cases of pregnancy in women with primary aldosteronism have been reported, suggesting the disorder is significantly underdiagnosed in confinement. Accurate diagnosis is complicated by physiological changes in the renin-angiotensin-aldosterone axis in pregnancy, leading to a risk of false negative results on screening tests. The course of primary aldosteronism during pregnancy is highly variable, although overall it is associated with a very high risk of fetal and maternal morbidity and mortality. The optimal management of primary aldosteronism during pregnancy is unclear, with uncertainty regarding the safety of mineralocorticoid antagonists and amiloride, their relative efficacy compared with the antihypertensive medications commonly used during pregnancy, and as to whether prognosis is improved by laparoscopic adrenalectomy where an adrenal adenoma can be demonstrated.

    Thrombocytopenia during pregnancy is quite common. Evaluation of blood counts of pregnant women has shown that thrombocytopenia is the second most common haematological problem in pregnancy, after anaemia. While mostly thrombocytopenia has no consequences for either the mother or the foetus, in some cases it is associated with substantial maternal and/or neonatal morbidity and mortality. It may result from a number of diverse aetiologies. Adequate knowledge of these causes will help the clinicians in making proper diagnosis and management of thrombocytopenia in pregnancy. The evaluation of thrombocytopenia is essential to rule out any systemic disorders that may affect pregnancy management as thrombocytopenia can present as an isolated finding or in combination with underlying conditions. In this concise review, we have provided the overview of thrombocytopenia diagnosed during pregnancy.

    Cancer complicates approximately 0.1% of all pregnancies. Primary tracheal carcinoma is one of very rarely seen tumors and the rate of its being seen makes up approximately % 0.2 of all tumors of respiratory tract. The patient, 28 years old, who has 28-weeks-pregnant, was diagnosed with primary tracheal adenocystic carcinoma. Patient was made operation as thoracotomy and tracheal tumor was removed at the 28th week of pregnancy. Patient was delivered with sectio abdominale at the 39th week of pregnancy. Primary tracheal adenocystic carcinoma is very rarely seen tumors and it is the first tracheal ACC with pregnancy case in literature to have been detected and surgically treated during pregnancy. We discussed primary tracheal adenocystic carcinoma and tracheal tumors during pregnancy with literature. PMID:22066040

    We report on an abdominal pregnancy in human immunodeficiency virus-positive mother, currently on antiretroviral therapy, which was discovered incidentally while training the obstetric ultrasound capacity building program. Although abdominal pregnancy is a rare form of ectopic pregnancy, it may be more common in women with HIV infection because they tend to have a higher rate of sexually transmitted diseases than the general population. The positive diagnosis of abdominal pregnancy is difficult to establish and is usually missed during prenatal assessment particularly in settings that lack routine ultrasound examination as is the case in most developing countries. For the management of abdominal pregnancy, surgical intervention is recommended and removal of the placenta is a key controversy. Ultrasonography is considered the front-line and most effective imaging method and an awareness with a high index of suspicion of abdominal pregnancy is vital for reducing associated high maternal and even higher perinatal mortality.

    During pregnancy, women often show a willingness to make positive lifestyle changes, such as smoking cessation, initiation of a vitamin regimen, improvement of their diet, and increases in their levels of exercise or physical activity. To study health outcomes in both pregnant mice and their offspring, we developed a model of controlled maternal exercise during mouse pregnancy. Female ICR and C57BL/6 mice underwent controlled wheel walking for 1 h daily, 5 d each week, at a speed of 6 m/min prior to and during pregnancy and nursing. Dam body weight, food consumption, pregnancy rates, litter size, pup weights and litter survival were used as markers of pregnancy success and were not significantly affected by controlled maternal exercise. The proposed exercise paradigm is a safe pregnancy intervention and can be explored further.

    Thrombocytopenia (TP) affects 7-10% of pregnant women. It occurs 4 times more frequently in pregnancy than in the non-pregnant women population. Women with thrombocytopenia in pregnancy are a heterogeneous and poorly known group. There are several possible causes of thrombocytopenia in pregnancy. The most common are: gestational thrombocytopenia (GE) (60-75%), preeclampsia (PE) and HELLP (hemolysis, elevated liver enzymes, low platelets) syndrome associated TP (21%), and idiopathic immune thrombocytopenia (ITP) (3-10%). Although thrombocytopenia diagnosed in pregnancy in most cases has a mild course, it has also been reported to be associated with a higher rate of preterm birth and premature detachment of the placenta. Some cases of severe thrombocytopenia with systemic involvement are associated with high risk of serious perinatal complications and require early diagnosis, careful clinical monitoring and medical treatment. The differential diagnosis and proper assessment of clinical risk of TP during pregnancy may be of great concern. The article discusses these issues, focusing on pathophysiology of TP in pregnancy.

    From 1969 to 1987, 35 pregnancies occurred in 31 women with renal transplant. Four of them were still pregnant when this study was concluded. There was one ectopic pregnancy. All patients received azathioprine and prednisone. In the majority of patients the glomerular filtration rate increased in a way similar to normal pregnant women. In five cases there was a progressive loss in renal function. In four of them this was attributed to preexistent renal damage. No toxemia occurred. Anemia developed during 11 pregnancies and blood transfusion was required for five women. Four patients had urinary tract infection which was easily controlled with antibiotics. One patient had severe arterial hypertension, secondary to chronic rejection. One patient developed jaundice reverted with reduction in azathioprine doses. One woman died of septicemia secondary to fetal death, during the 6th month of pregnancy. Twenty children were born with no abnormalities, although many of them were underweighted. Two thirds of pregnancies were delivered by cesarean section. No harm to the pelvic allograft occurred in vaginal deliveries. There have been 4 abortions (2 of them were induced with no medical indication). Four pregnancies (26 to 39 gestational weeks) ended in stillborn babies: the mothers had impaired renal function associated with hypertension and proteinuria. One newborn died of pulmonary infection two days after delivery. Another was born with microcephaly and polydactilia and survived 6 years. No breast feeding was allowed.

    Malignant germ cell tumors (MGCT) are a rare type of ovarian cancer with poorly understood behavior during pregnancy. This systematic review evaluated feto-maternal outcomes and management patterns of 102 ovarian MGCT-complicated pregnancies identified in PubMed/MEDLINE. Mean age was 25.8. The most common histology type was dysgerminoma (38.2%) followed by yolk sac tumor (30.4%). Abdomino-pelvic pain (35.3%) was the most common symptom. The majority were stage I disease (76.4%) with a mean tumor size of 17.9cm. Most cases had live births (77.5%) at term (56.6%). Tumor surgery without fetal conservation took place in 22 (21.6%) cases (Group 1). This group was characterized by the first trimester tumor detection and intervention, non-viable pregnancy, and frequent concurrent hysterectomy. There were 59 (57.8%) cases which underwent expectant management of pregnancy: mean delay 16.4 weeks for 46 (45.1%) cases with tumor surgery and fetal conservation (Group 2); and 7.8 weeks for 13 (12.7%) cases with tumor surgery after delivery (Group 3). The live birth rate in Groups 2 and 3 was 98.3%. There were 21 (20.6%) cases in which the tumor was incidentally found intra/postpartum (Group 4). Group 2 showed the highest 5-year overall survival rate (92.8%) followed by Group 4 (79.5%), Group 3 (71.4%), and Group 1 (56.2%, p=0.028). Group 1 had more advanced-stage disease when compared to Group 2 (proportion of stages II-IV disease, 36.4% versus 11.4%, p=0.023). In multivariate analysis, age ≤20 (p=0.032) and stages II-IV (p=0.02) remained independent prognosticators for decreased overall survival in all cases. Expectant management of pregnancy was not associated with poor survival outcome in multivariate analysis (p=0.43). In conclusion, our analysis demonstrated that timing of tumor intervention and delivery significantly impacted feto-maternal outcome of ovarian MGCT-complicated pregnancies. It is suggested that early detection and tumor intervention with expectant

    OBJECTIVES While progress has been made to reduce adolescent pregnancies in the United States, rates of unplanned pregnancy among young adults (18–29 years) remain high. In this study, we assessed factors associated with perceived likelihood of pregnancy (likelihood of getting pregnant/getting partner pregnant in the next year) among sexually experienced young adults who were not trying to get pregnant and had ever used contraceptives. METHODS We conducted a secondary analysis of 660 young adults, 18–29 years old in the United States, from the cross-sectional National Survey of Reproductive and Contraceptive Knowledge. Logistic regression and classification tree analyses were conducted to generate profiles of young adults most likely to report anticipating a pregnancy in the next year. RESULTS Nearly one-third (32%) of young adults indicated they believed they had at least some likelihood of becoming pregnant in the next year. Young adults who believed that avoiding pregnancy was not very important were most likely to report pregnancy likelihood (odds ratio [OR], 5.21; 95% CI, 2.80–9.69), as were young adults for whom avoiding a pregnancy was important but not satisfied with their current contraceptive method (OR, 3.93; 95% CI, 1.67–9.24), attended religious services frequently (OR, 3.0; 95% CI, 1.52–5.94), were uninsured (OR, 2.63; 95% CI, 1.31–5.26), and were likely to have unprotected sex in the next three months (OR, 1.77; 95% CI, 1.04–3.01). DISCUSSION These results may help guide future research and the development of pregnancy prevention interventions targeting sexually experienced young adults. PMID:25782849

    Objectives: To evaluate the dental anxiety level and the degree of acceptance of laser assisted pedodontic treatments from the children part. Also, we want to underline the advantages of laser use in pediatric dentistry, to make this technology widely used in treating dental problems of our children patients. Methods: Thirty pediatric dental patients presented in the Department of Pedodontics, University of Medicine and Pharmacy "Victor Babeş", Timişoara were evaluated using the Wong-Baker pain rating scale, wich was administered postoperatory to all patients, to assess their level of laser therapy acceptance. Results: Wong-Baker faces pain rating scale (WBFPS) has good validity and high specificity; generally it's easy for children to use, easy to compare and has good feasibility. Laser treatment has been accepted and tolerated by pediatric patients for its ability to reduce or eliminate pain. Around 70% of the total sample showed an excellent acceptance of laser dental treatment. Conclusions: Laser technology is useful and effective in many clinical situations encountered in pediatric dentistry and a good level of pacient acceptance is reported during all laser procedures on hard and soft tissues.

    Two foaming vaginal tablets containing nonoxynol-9 (OVT-n) or menfegol (OVT-m) were studied to evaluate safety, effectiveness and acceptability. The study was conducted at the Chulalongkorn University, Institute of Health Research, Bangkok, Thailand. One-hundred-two women randomly assigned to one of the two types of tablets were scheduled for follow-up visits at 1, 3, 6 and 12 months. Although there were differences between the two groups in the gross cumulative 12-month life table rates and 12-month continuation rates, these differences were not statistically significant. Twelve-month discontinuation rates for accidental pregnancy were 31.7 per 100 women for OVT-n group and 25.3 per 100 women for the OVT-m group. Seventeen of the total 22 pregnancies occurred due to use failure. This study indicates that the regular and proper use of OVT-n or OVT-m tablets are comparable and are a safe means of birth control. Although a few product-related (burning) or medical complaints were reported by both groups of tablet users, it seems that the vaginal contraceptive is an acceptable method for fertility control in a suitable population who will use it regularly and properly.

    Frequency of pregnancy among childbearing age women with end-stage renal disease (ESRD) undergoing long-term periodic dialysis ranges from 1% to 7%. Although pregnancy in dialysis women with ESRD is considered a largely high-risk pregnancy, occurrence of successful pregnancy is not impossible with success rates approaching 70%. Rates of successful pregnancy are greatly impacted by early pregnancy diagnosis and preserved residual renal functions. Herein, to the best of our knowledge, we report the first case of successful pregnancy (despite late diagnosis at 14 weeks of gestation) in a 31-year-old peritoneal dialysis patient with bilateral nephrectomy and no whatsoever preserved residual renal function. Moreover, a literature review on pregnancy in dialysis patients is presented. PMID:24198990

    After ovulation, non-pregnant female giant pandas experience pseudopregnancy. During pseudopregnancy, non-pregnant females exhibit physiological and behavioral changes similar to pregnancy. Monitoring hormonal patterns that are usually different in pregnant mammals are not effective at determining pregnancy status in many animals that undergo pseudopregnancy, including the giant panda. Therefore, a physiological test to distinguish between pregnancy and pseudopregnancy in pandas has eluded scientists for decades. We examined other potential markers of pregnancy and found that activity of the acute phase protein ceruloplasmin increases in urine of giant pandas in response to pregnancy. Results indicate that in term pregnancies, levels of active urinary ceruloplasmin were elevated the first week of pregnancy and remain elevated until 20-24 days prior to parturition, while no increase was observed during the luteal phase in known pseudopregnancies. Active ceruloplasmin also increased during ultrasound-confirmed lost pregnancies; however, the pattern was different compared to term pregnancies, particularly during the late luteal phase. In four out of the five additional reproductive cycles included in the current study where females were bred but no birth occurred, active ceruloplasmin in urine increased during the luteal phase. Similar to the known lost pregnancies, the temporal pattern of change in urinary ceruloplasmin during the luteal phase deviated from the term pregnancies suggesting that these cycles may have also been lost pregnancies. Among giant pandas in captivity, it has been presumed that there is a high rate of pregnancy loss and our results are the first to provide evidence supporting this notion.

    Pregnancy in patients with ESRD is rare and remains especially challenging. Because endocrine abnormalities and sexual dysfunction decrease fertility, conception rates have been remarkably low in this patient population. Moreover, when pregnancy does occur, hypertension, preeclampsia, anemia, intrauterine growth restriction, preterm delivery, stillbirth, and other complications can decrease the rate of a successful outcome. However, recent experiences with intensive hemodialysis managed by a multidisciplinary team are encouraging with respect to better overall outcomes for mothers and infants. In this article, we discuss the main causes of decreased fertility in dialysis-dependent women, review outcomes and complications of pregnancy among dialysis patients with a special focus on recent intensive hemodialysis data, and summarize the current best strategy to manage pregnant women on dialysis.

    The determination of the magnitude of sonic boom exposure which would be acceptable to the general population requires, as a starting point, a method to assess and compare individual sonic booms. There is no consensus within the scientific and regulatory communities regarding an appropriate sonic boom assessment metric. Loudness, being a fundamental and well-understood attribute of human hearing was chosen as a means of comparing sonic booms of differing shapes and amplitudes. The figure illustrates the basic steps which yield a calculated value of loudness. Based upon the aircraft configuration and its operating conditions, the sonic boom pressure signature which reaches the ground is calculated. This pressure-time history is transformed to the frequency domain and converted into a one-third octave band spectrum. The essence of the loudness method is to account for the frequency response and integration characteristics of the auditory system. The result of the calculation procedure is a numerical description (perceived level, dB) which represents the loudness of the sonic boom waveform.

    The purpose of the present study was to examine pregnancy and delivery among Finnish endurance athletes at the national top level. A questionnaire concerning first pregnancy was sent to 30 Finnish endurance athletes who had been at national top level in cross-country skiing, running, speed-skating or orienteering. Data on labour were collected retrospectively through a questionnaire and from the diaries in the hospital concerned. The next primipara in the diaries formed a member of the control group. Twenty-three athletes (77%) had regular menstrual cycles, seven (23%) had irregularities, and four of them had received hormonal treatment for this. Seven athletes (23%) had experienced spontaneous abortion during the first trimester in previous pregnancy. Sixteen (53%) did not notice any change in their exercise performance, three (10%) subjectively felt themselves to be in a better physical condition, and seven (23%) felt themselves to be in a worse condition than before the pregnancy. Four did not respond on the question. After delivery, 18 athletes continued to compete, the median interval being 8.2 months (range 2-24 months). Two of them (11%) achieved a better condition than before the pregnancy, 11 (61%) reached the same level and five (28%) did not achieve the same performance level. There were no significant differences in labour parameters between the athletes and controls. Endurance training had no harmful side-effects on the pregnancies or deliveries of the athletes. The effect of pregnancy on exercise performance is individual.

    Prolactinomas are the most prevalent functional benign pituitary tumors due to a pituitary micro- or macroadenoma. The majority of patients presents with infertility and gonadal dysfunction. A dopamine agonist (DA) (bromocriptine or cabergoline) is the treatment of choice that can normalize prolactin levels, reduce tumor size, and restore ovulation and fertility. Cabergoline generally preferred over bromocriptine because of its higher efficacy and tolerability. Managing prolactinomas during pregnancy may be challenging. During pregnancy, the pituitary gland undergoes global hyperplasia due to a progressive increase in serum estrogens level that may lead to increase of the tumor volume with potential mass effect and visual loss. The risk of tumor enlargement may occur in 3% of those with microadenomas, 32% in those with macroadenomas that were not previously operated on, and 4.8% of those with macroadenomas with prior ablative treatment. Though both drugs appear to be safe during pregnancy, the data on fetal exposure to DAs during pregnancy have been reported with bromocriptine far exceeds that of cabergoline with no association of increased risk of pregnancy loss and premature delivery. It is advisable to stop the use of DAs immediately once pregnancy is confirmed, except in the case of women with invasive macroprolactinomas or pressure symptoms. This review outlines the therapeutic approach to prolactinoma during pregnancy, with emphasis on the safety of available DA therapy. PMID:26074878

    Cervical pregnancy is a rare type of ectopic pregnancy and it represents <1% of all ectopic pregnancies. Early diagnosis and medical management with systemic or local administration of methotrexate is the treatment of choice. If the pregnancy is disturbed, it may lead to massive hemorrhage, which may require hysterectomy to save the patient. We report three cases of cervical pregnancy managed successfully with different approaches of management. Our first case, 28 years old G3P2L2 with previous two lower segment cesarean sections, presented with bleeding per vaginum following 6 weeks of amenorrhea. Clinical examination followed by transvaginal ultrasound confirmed the diagnosis of cervical pregnancy. Total abdominal hysterectomy was done in view of intractable bleeding to save the patient. The second case, a 26-year-old second gravida with previous normal vaginal delivery presented with pain abdomen and single episode of spotting per vaginum following 7 weeks of amenorrhea. Transvaginal ultrasound revealed empty endometrial cavity, closed internal os with gestational sac containing live fetus of 7 weeks gestational age in cervical canal and she was treated with intra-amniotic potassium chloride followed by systemic methotrexate. Follow up with serum beta human chorionic gonadotropin level revealed successful outcome. Our third case, a 27-year-old primigravida with history of infertility treatment admitted with complaints of bleeding per vaginum for 1 day following 8 weeks amenorrhea. She was diagnosed as cervical pregnancy by clinical examination, confirmed by transvaginal ultrasonography and subsequently managed by dilation and curettage with intracervical Foleys' ballon tamponade.

  11. Anaemia in pregnancy.

    Anaemia in pregnancy, defined as a haemoglobin concentration (Hb) < 110 g/L, affects more than 56 million women globally, two thirds of them being from Asia. Multiple factors lead to anaemia in pregnancy, nutritional iron deficiency anaemia (IDA) being the commonest. Underlying inflammatory conditions, physiological haemodilution and several factors affecting Hb and iron status in pregnancy lead to difficulties in establishing a definitive diagnosis. IDA is associated with increased maternal and perinatal morbidity and mortality, and long-term adverse effects in the new born. Strategies to prevent anaemia in pregnancy and its adverse effects include treatment of underlying conditions, iron and folate supplementation given weekly for all menstruating women including adolescents and daily for women during pregnancy and the post partum period, and delayed clamping of the umbilical cord at delivery. Oral iron is preferable to intravenous therapy for treatment of IDA. B12 and folate deficiencies in pregnancy are rare and may be due to inadequate dietary intake with the latter being more common. These vitamins play an important role in embryo genesis and hence any relative deficiencies may result in congenital abnormalities. Finding the underlying cause are crucial to the management of these deficiencies. Haemolytic anaemias rare also rare in pregnancy, but may have life-threatening complications if the diagnosis is not made in good time and acted upon appropriately.

  12. Thrombophilia, thrombosis and pregnancy.

    The risk of venous thromboembolism (VTE) in pregnancy is 0.05-1.8%, six times greater than in the non-pregnant state, and pulmonary embolism remains the most common cause of maternal death. Maternal age, previous history of VTE, Caesarean section and the presence of thrombophilia, significantly increase the risk of VTE. Acquired or hereditary thrombophilia occur in almost two-thirds of women presenting with recurrent miscarriages, pre-eclampsia, intrauterine growth restriction, abruptio placentae, or stillbirth, which are associated with microvascular thrombosis in placental blood vessels. Women with VTE during pregnancy and especially those with thrombophilia require individualized management, based on the type of defect, the family history and the presence of additional risk factors. These factors are important in determining the dose and duration of antithrombotic therapy during pregnancy and the puerperium, and the thromboprophylactic strategy for future pregnancies. Oral anticoagulants are now seldom used during pregnancy because of their significant side effects. Low-molecular-weight heparins (LMWHs) are increasingly replacing unfractionated heparin in the prevention and treatment of VTE during pregnancy. LMWHs have also been shown to be effective in improving the outcome of pregnancy in women with previous obstetric complications.

    Sexual behavior may be altered during pregnancy. The authors aimed to investigate the behavior of pregnant women in terms of level of sexual initiative and change in sexual positions for intercourse. The authors conducted a retrospective research with 156 pregnant Brazilian women who completed a questionnaire. Before pregnancy, both partners usually initiated sex, whereas during pregnancy, the male partner generally did. In general, women who took the sexual initiative showed better scores in the sexuality variables. During pregnancy, the use of each sexual position reduced significantly. Couples in which both partners take the sexual initiative tend to accept a wider variety of sexual positions.

    Key Clinical Message Ovarian pregnancy is one of the rarest types of extrauterine pregnancy. Its preoperative diagnosis remains a challenge since it presents quite similarly to tubal pregnancy and complicated ovarian cysts. Although in most cases, histology is necessary to confirm the diagnosis, we present an ovarian pregnancy in a teenager, correctly diagnosed during ultrasound examination. PMID:26576271

    Abstract Rationale: Pregnancy is a complicated physiological process. Physiological leukocytosis often takes place and it is primarily related to the increased circulation of neutrophils, especially during the last trimester of pregnancy. Noncongenital agranulocytosis during pregnancy is rare and reported only occasionally, while in most of the cases, the agranulocytosis has already occurred prior to pregnancy or induced by identified factors such as antibiotics, antithyroid agents, or cytotoxic agents. Gestation-induced agranulocytosis has not been reported, so we present a case of gestation-induced agranulocytosis in this article. Patients concern: In this case, we present a Chinese woman (aged 25) in her 38th week of the first gestation who had the complication of agranulocytosis. No abnormality was detected in regular examinations before pregnancy and in the first trimester. Since the last trimester of pregnancy, the patient began to suffer from agranulocytosis and intermittent fever, the maximum being temperature 38.8°C. At admission, the neutrophil granulocytes were 0.17 × 109 L−1 and the bone marrow biopsy showed that agranulocytosis was detected, but the levels of red blood cell and megalokaryocyte were normal. In addition, antinuclear antibodies were detected at a dilution of 1:40, but anti-dsDNA, antiphospholipid antibody, and neutrophil granulocyte antibody were negative. Diagnoses: The patient was empirically treated as having pneumonia. Interventions: We tried to use granulocyte colony-stimulating factor, γ-globulin, glucocorticoids, antibiotics, and antifungi agents to treat the patient, but her symptoms were not alleviated until the patient had a cesarean section. Outcomes: After 24 hours of cesarean section, the temperature and neutrophil granulocyte returned to normal. After a year of follow-up, we found that the patient and the baby were healthy. Lessons: Agranulocytosis during pregnancy seems to be associated with immunosuppression

    More and increasingly young adolescents are sexually active and pay less or no attention to contraception. The pregnancy rate among adolescents has been definitely increasing in recent years and especially among the youngest. This entails a large proportion of medicosomatic and also psychosocial risks such as premature labour and delivery as well as social disadvantages. Moreover, abortions have greatly increased. e.g. by 20% in 2001. Among the causes besides earlier maturity we may assume inadequate sex education falling short of cognitive capacity and emotional needs as well as difficult social problems with deficiencies in tenderness requirements and poor prospects of vocational training and professional career 8 examples, case reports). The overall situation pre-programmes medium-term and long-term consequences such as deficient school education and training, financial dependence and excessive financial and emotional strain on mother and child. A considerable gap in this regard can be filled by medical health promotion in step with physical and mental development, as well as by primary and secondary prevention in respect of information deficits, within the framework of a sound relationship of trust and reliability between the physician and the (female) patient.

    The presentation of urolithiasis is often dramatic, but rarely is it more anxiety provoking than during pregnancy. The evaluation and the intervention are often approached with trepidation as the health of the mother and the fetus must be taken into account. The typical diagnostic course and surgical management used in the nonpregnant population must be reevaluated in the expectant mother. Failure to promptly diagnose and manage urolithiasis during pregnancy may have adverse consequences for mother and child. The authors present a review of the relevant anatomic and physiologic changes of pregnancy as they affect stone disease and outline options for radiologic evaluation and surgical management.

    Sleep disturbances are common in pregnancy and may be influenced by a multitude of factors. Pregnancy physiology may predispose to sleep disruption but may also result in worsening of some underlying sleep disorders, and the de novo development of others. Apart from sleep disordered breathing, the impact of sleep disorders on pregnancy, fetal, and neonatal outcomes is poorly understood. In this article, we review the literature and discuss available data pertaining to the most common sleep disorders in perinatal women. These include restless legs syndrome, insomnia, circadian pattern disturbances, narcolepsy, and sleep-disordered breathing.

  19. Renal Failure in Pregnancy.

    Renal failure during pregnancy affects both mother and fetus, and may be related to preexisting disease or develop secondary to diseases of pregnancy. Causes include hypovolemia, sepsis, shock, preeclampsia, thrombotic microangiopathies, and renal obstruction. Treatment focuses on supportive measures, while pharmacologic treatment is viewed as second-line therapy, and is more useful in mitigating harmful effects than treating the underlying cause. When supportive measures and pharmacotherapy prove inadequate, dialysis may be required, with the goal being to prolong pregnancy until delivery is feasible. Outcomes and recommendations depend primarily on the underlying cause.

    Hypertension is a common complication of pregnancy. Preeclampsia, in particular, is associated with substantial risk to both the mother and the fetus. Several risk factors have been recognized to predict risk for preeclampsia. However, at present no biomarkers have sufficient discriminatory ability to be useful in clinical practice, and no effective preventive strategies have yet been identified. Commonly used medications for the treatment of hypertension in pregnancy include methyldopa and labetalol. Blood pressure thresholds for initiating antihypertensive therapy are higher than outside of pregnancy. Women with prior preeclampsia are at increased risk of hypertension, cardiovascular disease, and renal disease.
