    Full Text Available BACKGROUND: Elective repeat caesarean delivery (ERCD rates have been increasing worldwide, thus prompting obstetric discourse on the risks and benefits for the mother and infant. Yet, these increasing rates also have major economic implications for the health care system. Given the dearth of information on the cost-effectiveness related to mode of delivery, the aim of this paper was to perform an economic evaluation on the costs and short-term maternal health consequences associated with a trial of labour after one previous caesarean delivery compared with ERCD for low risk women in Ireland. METHODS: Using a decision analytic model, a cost-effectiveness analysis (CEA was performed where the measure of health gain was quality-adjusted life years (QALYs over a six-week time horizon. A review of international literature was conducted to derive representative estimates of adverse maternal health outcomes following a trial of labour after caesarean (TOLAC and ERCD. Delivery/procedure costs derived from primary data collection and combined both "bottom-up" and "top-down" costing estimations. RESULTS: Maternal morbidities emerged in twice as many cases in the TOLAC group than the ERCD group. However, a TOLAC was found to be the most-effective method of delivery because it was substantially less expensive than ERCD (€ 1,835.06 versus € 4,039.87 per women, respectively, and QALYs were modestly higher (0.84 versus 0.70. Our findings were supported by probabilistic sensitivity analysis. CONCLUSIONS: Clinicians need to be well informed of the benefits and risks of TOLAC among low risk women. Ideally, clinician-patient discourse would address differences in length of hospital stay and postpartum recovery time. While it is premature advocate a policy of TOLAC across maternity units, the results of the study prompt further analysis and repeat iterations, encouraging future studies to synthesis previous research and new and relevant evidence under a single

    Elective repeat caesarean delivery (ERCD) rates have been increasing worldwide, thus prompting obstetric discourse on the risks and benefits for the mother and infant. Yet, these increasing rates also have major economic implications for the health care system. Given the dearth of information on the cost-effectiveness related to mode of delivery, the aim of this paper was to perform an economic evaluation on the costs and short-term maternal health consequences associated with a trial of labour after one previous caesarean delivery compared with ERCD for low risk women in Ireland.

    Repeat caesarean delivery (RCD) ranks as the top reason for the high caesarean rates in Taiwan. More than 90% of Taiwanese women who have had a previous caesarean delivery chose RCD following their next pregnancy. To explore the decision-making processes regarding RCD in Taiwanese women. A qualitative approach with grounded theory was used to conduct this research. Participants were recruited from a private medical centre in northern Taiwan. Methods of data collection include in-depth interviews, observation, and field notes. Constant comparative analytical techniques were employed for data analysis. A total of 16 women chose RCD. Ensuring the well-being of mother and fetus was the core theme. Women's decisions were influenced by both internal factors (previous negative experience of birth, concern about uterine rupture, fixing the scar of previous caesarean and current pregnancy situation) and external factors (obstetrician's recommendation, the experience of female significant others, an inaccurate information from internet and the unconditional financial coverage from Health National Insurance). Decision-making processes involved searching information regarding mode of birth, evaluating vaginal birth risk, trusting obstetricians' professional judgment, and a lack of progress during the course of labour. The well-being of mother and fetus is the major concern affecting mothers' decisions regarding RCD. The majority of Taiwanese women participate passively in the decision-making process regarding their options for mode of birth. In the present study, women choices were primarily guided by reducing the risk of uterine rupture. Hospitals should reduce unnecessary induction interventions. Obstetricians should inform women of the risks and benefits of various birth modes. The government could establish a website that provides a clear explanation of the criteria for the government to financially cover the costs of RCD in order to assist women to make optimal birth

She had history of haematuria during menstruation and her menstrual flow is scanty. Her first baby was female and alive, but her second baby was stillborn following prolonged and obstructed labour. This has been continuously blamed by family and others for happening that events. Her fistula was confirmed by ultrasound scan, histerography and cystoscopy. The vesicouterine fistula was treated by local repair with omental patch through transperitoneal approach.

    OBJECTIVE: Given international variation in obstetric practices and outcomes, comparison of labour outcomes in different ethnic groups could provide important information regarding the underlying reasons for rising caesarean delivery rates. Increasing numbers of women from Eastern European countries are now delivering in Irish maternity hospitals. We compared labour outcomes between Irish and Eastern European (EE) women in a large tertiary referral center. STUDY DESIGN: This was a prospective consecutive cohort study encompassing a single calendar year. The cohort comprised 5550 Irish and 867 EE women delivered in a single institution in 2009. Women who had multiple pregnancies, breech presentation, and elective or pre-labour caesarean sections (CS) were excluded. Data obtained from birth registers included maternal age, nationality, parity, gestation, onset of labour, mode of delivery and birth weight. RESULTS: The overall intrapartum CS rate was 11.4% and was significantly higher in Irish compared to EE women (11.8% vs. 8.8%; p=0.008). The proportion of primiparas was lower in Irish compared to EE women (44.8% vs. 63.6%; p<0.0001). The intrapartum CS rate was almost doubled in Irish compared to EE primiparas (20.7% vs. 11.0%; p<0.0001). Analysis of primiparas according to labour onset revealed a higher intrapartum CS rate in Irish primiparas in both spontaneous (13.5% vs. 7.2%; p<0.0001) and induced labour (29.5% vs. 19.3%; p=0.005). Irish women were older with 19.7% of primiparas aged more than 35, compared to 1.6% of EE women (p<0.0001). The primigravid CS rate in Irish women was significantly higher in women aged 35 years or older compared women aged less than 35 (30.6% vs. 18.3%; p<0.0001) consistent in both spontaneous and induced labour. The primiparous induction rate was 45.4% in Irish women compared to 32% in EE women, and more Irish women were induced before 41 weeks gestation. CONCLUSION: The results highlight that primigravid intrapartum CS rates were

    Full Text Available Caesarean section (CS rates have been increasing worldwide and have caused concerns. For meaningful comparisons to be made World Health Organization recommends the use of the Ten-Group Robson classification as the global standard for assessing CS rates. 2625 women who birthed over a 12-month period were analysed using this classification. Women with previous CS (group 5 comprised 10.9% of the overall 23.5% CS rate. Women with one previous CS who did not attempt VBAC contributed 5.3% of the overall 23.5% CS rate. Second largest contributor was singleton nulliparous women with cephalic presentation at term (5.1% of the total 23.5%. Induction of labour was associated with higher CS rate (groups 1 and 3 (24.5% versus 11.9% and 6.2% versus 2.6%, resp.. For postdates IOL we recommend a gatekeeper booking system to minimise these being performed <41 weeks. We suggest setting up dedicated VBAC clinic to support for women with one previous CS. Furthermore review of definition of failure to progress in labour not only may lower CS rates in groups 1 and 2a but also would reduce the size of group 5 in the future.

    To audit the data of caesarean sections carried out in single-handed-run small private hospitals on the basis of the modified Robson criteria (Canada), to know the changing trends of caesarean sections over a considerable duration of time (15 years) in private sector, and to focus on a particular group out of the classification of caesarean section in the efforts to reduce the caesarean section rate. It is a retrospective observational study of 7342 caesarean section cases carried out in different small private maternity hospitals over a period of 15 years. The data analysed by applying the modified Robson criteria (Canada) and the changing trends were studied in the view of reducing caesarean section rate. Statistically significant increasing trend was observed in groups of both primary and repeat caesarean section cases done before the onset of labour in the last 5 years. Auditing the data of caesarean sections on the basis of the modified Robson criteria (Canada) is a better way of classification as compared to Ten Group Classification System (TGCS). The change in trends is seen only in the last 5 years, which suggests that there is shift in attitude of the obstetricians of small private hospitals in performing caesarean sections before onset of labour than performing it after the onset of labour. Our analysis suggests the obstetricians from small private hospitals to target groups 2B, 4B and 5C.

    Full Text Available BACKGROUND Today, there is a concern over the rising caesarean delivery both in the developed and developing countries across the world. It has been observed that both primary and repeat caesarean deliveries have been increasing at an alarming rate. Indications for caesarean deliveries also shows changing trends in the present scenario. The main aim of this study is to compare the caesarean delivery rates over the last one decade. The objective behind the study is to understand the contributing factors for the new trends. MATERIALS AND METHODS For this study, the data was collected in a retrospective manner from all the deliveries that occurred between July 1, 2005, to June 30, 2006, and July 2015 to June 30, 2016, in the Department of Obstetrics and Gynaecology, Karwar Institute of Medical Science, Karwar. A cohort of 2752 delivered women were studied. Among the caesarean births, the indications for both the primary and repeat caesarean sections were studied. After analysing the caesarean births from total live births, the rate for both primary and repeat caesarean were calculated. RESULTS The caesarean delivery rate is increased from 167 to 263 for 1000 live births with increase in primary caesarean delivery rate from 101 (10.1% to 187 (18.7% per 1000 live births in last one decade. Foetal distress, cephalopelvic disproportion, arrest of descent, multiple gestations, breech presentation contributed to this increase. CONCLUSION There is an increase in the total caesarean rate with significant rise in the primary caesarean rate in the last one decade.

    Full Text Available BACKGROUND: Caesarean delivery (CD rates are commonly used as an indicator of quality in obstetric care and risk adjustment evaluation is recommended to assess inter-institutional variations. The aim of this study was to evaluate whether the Ten Group classification system (TGCS can be used in case-mix adjustment. METHODS: Standardized data on 15,255 deliveries from 11 different regional centers were prospectively collected. Crude Risk Ratios of CDs were calculated for each center. Two multiple logistic regression models were herein considered by using: Model 1- maternal (age, Body Mass Index, obstetric variables (gestational age, fetal presentation, single or multiple, previous scar, parity, neonatal birth weight and presence of risk factors; Model 2- TGCS either with or without maternal characteristics and presence of risk factors. Receiver Operating Characteristic (ROC curves of the multivariate logistic regression analyses were used to assess the diagnostic accuracy of each model. The null hypothesis that Areas under ROC Curve (AUC were not different from each other was verified with a Chi Square test and post hoc pairwise comparisons by using a Bonferroni correction. RESULTS: Crude evaluation of CD rates showed all centers had significantly higher Risk Ratios than the referent. Both multiple logistic regression models reduced these variations. However the two methods ranked institutions differently: model 1 and model 2 (adjusted for TGCS identified respectively nine and eight centers with significantly higher CD rates than the referent with slightly different AUCs (0.8758 and 0.8929 respectively. In the adjusted model for TGCS and maternal characteristics/presence of risk factors, three centers had CD rates similar to the referent with the best AUC (0.9024. CONCLUSIONS: The TGCS might be considered as a reliable variable to adjust CD rates. The addition of maternal characteristics and risk factors to TGCS substantially increase the

    Summary of the impact of Caesarean section on anal incontinence. Review. Department of Gynaecology and Obstetrics, Charles University and University Hospital Plzen. Review of the current international literature. Currently, Caesarean section is not considered to reduce symptoms of anal incontinence. If there is any reduction of symptoms, that remains only for a short term (40% in 3 months after the delivery in the largest trial). In a long term, virtually in no trial has been observed any difference, and others, non-obstetrical factors (particularly aging) prevail. Current knowledge does not allow to assess sufficiently pros and cons of Caesarean compared to vaginal delivery. High risk groups, that would profit from elective Ceasarean, have not been clearly identified yet.

    Caesarean sections (CS) have significantly increased worldwide and a previous CS is nowadays an important and increasingly reported indication to perform a repeat CS. There is a paucity of information in Switzerland on the incidence of repeat CS after previous CS and relationship between the rates of vaginal birth after CS (VBAC). The aim of this study was to analyse the actual trend in VBAC in Switzerland. We performed a retrospective cohort study to analyse the proportion of VBAC among all pregnant women with previous sections which give birth during two time periods (group 1:1998/1999 vs. group 2:2004/2005) in our tertiary care referral hospital and in the annual statistics of Swiss Women's Hospitals (ASF-Statistics). In addition, the proportion of induction of labour after a previous caesarean and its success was analysed. In both cohorts studied, we found a significant decrease of vaginal births (p Switzerland. There was no significant change in labour induction during the study period. While this trend might reflect an increasing demand for safety in pregnancy and childbirth, it concomitantly increases maternal risks of further pregnancies, and women need to be appropriately informed about long-term risks.

    Researchers commonly collect repeated measures on individuals nested within groups such as students within schools, patients within treatment groups, or siblings within families. Often, it is most appropriate to conceptualize such groups as dynamic entities, potentially undergoing stochastic structural and/or functional changes over time. For instance, as a student progresses through school, more senior students matriculate while more junior students enroll, administrators and teachers may turn over, and curricular changes may be introduced. What it means to be a student within that school may thus differ from 1 year to the next. This article demonstrates how to use multilevel linear models to recover time-varying group effects when analyzing repeated measures data on individuals nested within groups that evolve over time. Two examples are provided. The 1st example examines school effects on the science achievement trajectories of students, allowing for changes in school effects over time. The 2nd example concerns dynamic family effects on individual trajectories of externalizing behavior and depression. PsycINFO Database Record (c) 2013 APA, all rights reserved.

    Full Text Available Abstract Background Caesarean section rates continue to increase worldwide with uncertain medical consequences. Auditing and analysing caesarean section rates and other perinatal outcomes in a reliable and continuous manner is critical for understanding reasons caesarean section changes over time. Methods We analyzed data on 97,095 women delivering in 120 facilities in 8 countries, collected as part of the 2004-2005 Global Survey on Maternal and Perinatal Health in Latin America. The objective of this analysis was to test if the "10-group" or "Robson" classification could help identify which groups of women are contributing most to the high caesarean section rates in Latin America, and if it could provide information useful for health care providers in monitoring and planning effective actions to reduce these rates. Results The overall rate of caesarean section was 35.4%. Women with single cephalic pregnancy at term without previous caesarean section who entered into labour spontaneously (groups 1 and 3 represented 60% of the total obstetric population. Although women with a term singleton cephalic pregnancy with a previous caesarean section (group 5 represented only 11.4% of the obstetric population, this group was the largest contributor to the overall caesarean section rate (26.7% of all the caesarean sections. The second and third largest contributors to the overall caesarean section rate were nulliparous women with single cephalic pregnancy at term either in spontaneous labour (group 1 or induced or delivered by caesarean section before labour (group 2, which were responsible for 18.3% and 15.3% of all caesarean deliveries, respectively. Conclusion The 10-group classification could be easily applied to a multicountry dataset without problems of inconsistencies or misclassification. Specific groups of women were clearly identified as the main contributors to the overall caesarean section rate. This classification could help health care

    2013-01-01

    Objective: To develop a scoring system for the prediction of successful vaginal birth after caesarean section, following induction of labour with intra-vaginal E2 gel (Glandin). Methods: The cross-sectional study was conducted from January 2010 to August 2011, at the Pakistan Institute of Medical Sciences in Islamabad. Trial of labour in previous one caesarean section, undergoing induction with intra-vaginal E2 gel, was attempted in 100 women. They were scored according to six variables; maternal age; gestation; indications of previous caesarean; history of vaginal birth either before or after the previous caesarean; Bishop score and body mass index. Multivariate and univariate logistic regression analysis was used to develop the scoring system. Results: Of the total, 67 (67%) women delivered vaginally, while 33 (33%) ended in repeat caesarean delivery. Among the subjects, 55 (55%) women had no history of vaginal delivery either before or after previous caesarean section; 15 (15%) had history of vaginal births both before and after the previous caesarean; while 30 (30%) had vaginal delivery only after the previous caesarean section. Rates of successful vaginal birth after caesarean increased from 38% in women having a score of 0-3 to 58% in patients scoring 4-6. Among those having a score of 7-9 and 10-12, the success rates were 71% and 86% respectively. Conclusion: Increasing scores correlated with the increasing probability of vaginal birth after caesarean undergoing induction of labour. The admission VBAC scoring system is useful in counselling women with previous caesarean for the option of induction of labour or repeat caesarean delivery. (author)

  2. An overview of the health economic implications of elective caesarean section.

    2013-12-01

    The caesarean section rate has continued to increase in most industrialised countries, which raises a number of economic concerns. This review provides an overview of the health economic implications of elective caesarean section. It provides a succinct summary of the health consequences associated with elective caesarean section for both the infant and the mother over the perinatal period and beyond. It highlights factors that complicate our understanding of the health consequences of elective caesarean section, including inconsistencies in definitions and coding of the procedure, failure to adopt an intention-to-treat principle when drawing comparisons, and the widespread reliance on observational data. The paper then summarises the economic costs associated with elective caesarean section. Evidence is presented to suggest that planned caesarean section may be less costly than planned vaginal birth in some clinical contexts, for example where the singleton fetus lies in a breech position at term. In contrast, elective caesarean section (or caesarean section as a whole) appears to be more costly than vaginal delivery (either spontaneous or instrumented) in low-risk or unselected populations. The paper proceeds with an overview of economic evaluations associated with elective caesarean section. All are currently based on decision-analytic models. Evidence is presented to suggest that planned trial of labour (attempted vaginal birth) following a previous caesarean section appears to be a more cost-effective option than elective caesarean section, although its cost effectiveness is dependent upon the probability of successful vaginal delivery. There is conflicting evidence on the cost effectiveness of maternal request caesareans when compared with trial of labour. The paucity of evidence on the value pregnant women, clinicians and other groups in society place on the option of elective caesarean section is highlighted. Techniques that might be used to elicit

    The aim of the study is to investigate the benefits and the limits in using the soft cup vacuum extractor on the fetal scalp during the caesarean section. The prospective study includes 19 cases of caesarean sections (group A), with vacuum assisted delivery using the soft cup vacuum extractor on the fetal scalp (diameter 6 cm) and 25 cases (group B) of caesarean sections with usual, manual extraction of the head assisted by fundal compression. All of the patients had undergone a planned caesarean section on term in absence of uterine activity and preserved amniotic membranes. Our results doesn't show differences in the Apgar score on the first and 5-th minute in the newborns of the two groups. The duration of the scalp traction was significantly shorter (30 +/- 4 sec) in comparison to the classical manual extraction (53 +/- 21 sec). The mean duration for applying the vacuum cup was 10 sec and 25 sec for tractions. The total blood loose and total duration of the caesarean sections were shorter than in the control group. The applied traction with the vacuum cup was sufficient for head extraction and there was no need for additional fundal compression. In conclusion we consider that the extraction of the fetal head in high position in caesarean section with vacuum extractor is an easy, non traumatic and rapid method which can put away the need of rough and prolonged fundal compression and its consequences.

    One of the greatest contributors to the overall caesarean section rate is elective repeat caesarean section. Decisions around mode of birth are often complex for women and influenced by the views of the doctors and midwives who care for and counsel women. Women may be more likely to choose a repeat elective caesarean section (CS) if their health care providers lack skills and confidence in supporting vaginal birth after caesarean section (VBAC). To explore the views and experiences of providers in caring for women considering VBAC, in particular the decision-making processes and the communication of risk and safety to women. A descriptive interpretive method was utilised. Four focus groups with doctors and midwives were conducted. The central themes were: 'developing trust', 'navigating the system' and 'optimising support'. The impact of past professional experiences; the critical importance of continuity of carer and positive relationships; the ability to weigh up risks versus benefits; and the language used were all important elements. The role of policy and guidelines on providing standardised care for women who had a previous CS was also highlighted. Midwives and doctors in this study were positively oriented towards assisting and supporting women to attempt a VBAC. Care providers considered that women who have experienced a prior CS need access to midwifery continuity of care with a focus on support, information-sharing and effective communication.

    Establishing how collective behaviour emerges is central to our understanding of animal societies. Previous research has highlighted how universal interaction rules shape collective behaviour, and that individual differences can drive group functioning. Groups themselves may also differ considerably in their collective behaviour, but little is known about the consistency of such group variation, especially across different ecological contexts that may alter individuals' behavioural responses. Here, we test if randomly composed groups of sticklebacks differ consistently from one another in both their structure and movement dynamics across an open environment, an environment with food, and an environment with food and shelter. Based on high-resolution tracking data of the free-swimming shoals, we found large context-associated changes in the average behaviour of the groups. But despite these changes and limited social familiarity among group members, substantial and predictable behavioural differences between the groups persisted both within and across the different contexts (group-level repeatability): some groups moved consistently faster, more cohesively, showed stronger alignment and/or clearer leadership than other groups. These results suggest that among-group heterogeneity could be a widespread feature in animal societies. Future work that considers group-level variation in collective behaviour may help understand the selective pressures that shape how animal collectives form and function. PMID:29436496

    A study of 26 maternal deaths following 3647 caesarean sections was conducted in Eden Hospital from 1974-1977. During the time period there were 35,544 births and 308 total maternal deaths (8.74/1000). Indications for Caesarean sections included: 1) abnormal presentation; 2) cephalopelvic disproportion; 3) toxemia; 4) prolonged labor; 5) fetal distress; and 6) post-caesarean pregnancies. Highest mortality rates were among cephalopelvic disproportion, toxemia, and prolonged labor patients. 38.4% of the patients died due to septicaemia and peritonitis, but other deaths were due to preclampsia, shock, and hemorrhage. Proper antenatal care may have prevented anemia and preclampsia and treated other pre-existing or superimposed diseases.

    Objective: To determine the effect on subsequent mode of labour in case of previous elective caesarean for breech presentation in primiparous women. Study Design: A cohort study. Place and Duration of Study: Department of Obstetrics and Gynaecology, Liaquat University of Medical and Health Sciences, Jamshoro, Unit-1 and 1V, from January 2005 to December 2009. Methodology: All women with previous one elective caesarean section for breech or cephalic presentation visited OPD for antenatal checkup or admitted in emergency in maternity or labour ward were recruited for the study, while the women with previous 2 and 3 caesarean section were excluded from the study. The case records of these women were reviewed thoroughly, and entered in predesigned proforma. The main outcome measure was mode of labour in current pregnancy decided electively or adopted in emergency. Results: Out of the total, 131 (16.92%) women had previous elective caesarean section due to breech presentation while 643 (83.07%) women had previous elective caesarean section with cephalic presentation. Overall repeat caesarean section rate was 92 (70.22%) in women with previous breech presentation (n=131) in comparison with 475 (73.87%) women with previous cephalic presentation n=643 (RR=1.04, p=0.32). The vaginal birth rate after elective caesarean section due to breech presentation was 39 (29.77%) in comparison with 168 (26.12%) cases with previous cephalic presentation (RR=0.98, p=0.83). Conclusion: Women having elective caesarean section for breech presentation in their previous pregnancy had about 1 in 6 chance of having repeat elective caesarean section. (author)

  9. The compulsion to repeat relationships with abusive partners and how group therapy can help.

    2013-07-01

    The mystery of why some people are compelled to repeatedly engage in relationships with people who are cruel to them is frequently pondered in literature and psychology. The present paper posits that the etiology of this pathological relationship pattern derives from a parental relationship that was both highly exciting and highly frustrating. Spontaneous recapitulations of the passionate masochistic relationship in the therapy group allow the patient, the therapist and the group to appreciate the exact nature of the "bad" partner's appeal for the patient and its link to parental antecedents. In addition, the author suggests, group therapy can provide attachment experiences that are stimulating and rewarding enough to override the patient's attraction to the toxic partner(s) and build an enhanced capacity for intimacy. The cases of two patients are presented who spent three and a half years in the same long term psychodynamic group, and who, through the processes described above, successfully resolved their masochistic relationship patterns.

    Medical evidence indicates that 60-80% of women can achieve vaginal delivery after a previous lower segment caesarean section. Proper selection of patients for trial of scar and vigilant monitoring during labour will achieve successful maternal and perinatal outcome. The objective of our study is to establish the fact that vaginal delivery after one caesarean section has a high success rate in patients with previous one caesarean section for non-recurrent cause. Methods: The study was conducted in Ayub Teaching Abbottabad, Gynae-B Unit. All labouring patients, during the study period of five years, with previous one caesarean section and between 37 weeks to 41 weeks of gestation for a non-recurrent cause were included in the study. Data was recorded on special proforma designed for the purpose. Patients who had previous classical caesarean section, more than one caesarean section, and previous caesarean section with severe wound infection, transverse lie and placenta previa in present pregnancy were excluded. Foetal macrosomia (wt>4 kg) and severe IUGR with compromised blood flow on Doppler in present pregnancy were also not considered suitable for the study. Patients who had any absolute contraindication for vaginal delivery were also excluded. Results: There were 12505 deliveries during the study period. Total vaginal deliveries were 8790 and total caesarean sections were 3715. Caesarean section rate was 29.7%. Out of these 8790 patients, 764 patients were given a trial of scar and 535 patients delivered successfully vaginally (70%). Women who presented with spontaneous onset of labour were more likely to deliver vaginally (74.8%) as compared to induction group (27.1%). Conclusion: Trial of vaginal birth after caesarean (VBAC) in selected cases has great importance in the present era of the rising rate of primary caesarean section. (author)

    Toinvestigate CAG repeats variation of ATXN2 gene coding region in six ethnic groups that live in comparatively different environments, to evaluate whether these variations are under positive selection, and to find factors driving selection effects, 291 unrelated healthy individuals were collected from six ethnic groups and their STR geneotyping was performed. The frequencies of alleles and genotypes were counted and thereby Slatkin's linearized Fst values were calculated. The UPGMA tree against this gene was constructed. The MDS analysis among these groups was carried out as well. The results from the linearized Fst values indicated that there were significant evolutionary differences of the STR in ATXN2 gene between Hui and Yi groups, but not among the other 4 groups. Further analysis was performed by combining our data with published data obtained from other groups. These results indicated that there were significant differences between Japanese and other groups including Hui, Hani, Yunnan Mongolian, and Inner Mongolian. Both Hui and Mongolian from Inner Mongolia were significantly different from Han. In conclusion, the six ethnic groups had their own distribution characterizations of allelic frequencies of ATXN2 STR, and the potential cause of frequency changes in rare alleles could be the consequence of positive selection.

    Objective: To examine the effect of education on deciding about natural delivery in women opting for elective caesarean section. Methods: The quasi-experimental study was carried out between January and March 2012 and comprised a sample of 200 women in their third trimester of pregnancy attending women's clinics of Imam Ali Hospital, Zahedan, Iran, with the intention of having elective caesarean section. The subjects were voluntarily classified into three groups: one group received an educational package; the other had educational package along with group discussion, and the last one without any intervention was considered the control group. Post-test was conducted a month after intervention. Data were analysed using Kruskal Wallis, and logistic regression tests. Results: Group A represented the controls and had 100 (50%) women; Group B with the educational package had 40 (20%), while there were 60 (30%) women in Group C who had exposure to the educational package as well as group discussion. There were significant changes in behaviour in Group B and C (p <0.01) but no change among the controls in Group A. In Group C, 25 (42%) women decided to go for natural delivery, while 1 (2.5%) woman had a change of opinion in Group B. Four (4%) women in the control Group A had ultimately natural delivery, but they were all emergency cases. Conclusion: The two educational methods increased model construct scores, including awareness, attitude, perceived behaviour control, subjective norms and behavioural intention. Nevertheless, educational package in conjunction with group discussion was more effective in influencing the choice towards natural delivery. (author)

    Caesarean section (CS) rates are increasing worldwide and as a result repeat CS is common. The optimal mode of delivery in women with one previous CS is widely debated and the risks to the infant are understudied. The aim of the current study was to evaluate if women with a trial of labour after caesarean (TOLAC) had an increased odds of neonatal and infant death compared to women with an elective repeat CS (ERCS).

  14. Thirty years of the World Health Organization's target caesarean section rate: time to move on.

    Robson, Stephen J; de Costa, Caroline M

    2017-03-06

    It has been 30 years since the World Health Organization first recommended a "maximum" caesarean section (CS) rate of 15%. There are demographic differences across the 194 WHO member countries; recent analyses suggest the optimal global CS rate is almost 20%. Attempts to reduce CS rates in developed countries have not worked. The strongest predictor of caesarean delivery for the first birth of "low risk" women appears to be maternal age; a factor that continues to increase. Most women whose first baby is born by caesarean delivery will have all subsequent children by caesarean delivery. Outcomes that informed the WHO recommendation primarily relate to maternal and perinatal mortality, which are easy to measure. Longer term outcomes, such as pelvic organ prolapse and urinary incontinence, are closely related to mode of birth, and up to 20% of women will undergo surgery for these conditions. Pelvic floor surgery is typically undertaken for older women who are less fit for surgery. Serious complications such as placenta accreta occur with repeat caesarean deliveries, but the odds only reach statistical significance at the third or subsequent caesarean delivery. However, in Australia, parity is falling, and only 20% of women will have more than two births. We should aim to provide CS to women in need and to continue including women in the conversation about the benefits and disadvantages, both short and long term, of birth by caesarean delivery.

    Pregnant women who have previously had a caesarean birth and who have no contraindication for vaginal birth after caesarean (VBAC) may need to decide whether to choose between a repeat caesarean birth or to commence labour with the intention of achieving a VBAC. Women need information about their options and interventions designed to support decision-making may be helpful. Decision support interventions can be implemented independently, or shared with health professionals during clinical encounters or used in mediated social encounters with others, such as telephone decision coaching services. Decision support interventions can include decision aids, one-on-one counselling, group information or support sessions and decision protocols or algorithms. This review considers any decision support intervention for pregnant women making birth choices after a previous caesarean birth. To examine the effectiveness of interventions to support decision-making about vaginal birth after a caesarean birth.Secondary objectives are to identify issues related to the acceptability of any interventions to parents and the feasibility of their implementation. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 June 2013), Current Controlled Trials (22 July 2013), the WHO International Clinical Trials Registry Platform Search Portal (ICTRP) (22 July 2013) and reference lists of retrieved articles. We also conducted citation searches of included studies to identify possible concurrent qualitative studies. All published, unpublished, and ongoing randomised controlled trials (RCTs) and quasi-randomised trials with reported data of any intervention designed to support pregnant women who have previously had a caesarean birth make decisions about their options for birth. Studies using a cluster-randomised design were eligible for inclusion but none were identified. Studies using a cross-over design were not eligible for inclusion. Studies published in abstract form

    The alpha C protein is a protective surface-associated antigen of group B streptococci (GBS). The prototype alpha C protein of GBS (strain A909) contains nine identical tandem repeats, each comprising 82 amino acids, flanked by N- and C-terminal domains. Clinical isolates of GBS show variable numbers of repeats with a normal distribution and a median of 9 to 10 repeats. Here, we show that escape mutants of GBS expressing one-repeat alpha C protein were 100-fold more pathogenic than GBS expres...

    A twenty year old parturient with short stature presented to the hospital in early labour. An elective lower segment caesarean section(LSCS was planned in view of cephalopelvic disproportion. She had papers which suggested that she had been diagnosed as a case of achondroplasia though details were not available. Combined spinal epidural(CSE anaesthesia was planned in the patient in view of the death of her first baby following caesarean section under general anaesthesia. Repeatedly dry taps were achieved on attempting dural puncture. Dural puncture was abandoned and an 18 G epidural catheter was threaded via the Tuohy needle. Sensory block till T 6 was achieved with 6ml of local anaesthetic solution. The patient was stable during the intraoperative and postoperative period.

    What levels of total abatement can one hope for in a global climate agreement. Some potential answers to this question are provided by game theory. This working paper contains a critical discussion of two (prominent) game ,models that answer the question quite pessimistically. Both models take the n-person, infinitely repeated prisoner's dilemma game as their point of departure. The first model is a full information model and utilises the motion of a weakly re negotiation proof equilibrium. This results in the (maybe counterintuitive) prediction that an agreement that can provide high utility to the group will attract less total abatement than an agreement that can only provide low utility to the group. The second model assumes imperfect public information and utilises the notion of a trigger level equilibrium. This results in the (more intuitive) prediction that the level of total abatements will increase with improved verification techniques for a given player set. Still the level of total abatements decrease with an increasing player set for a given verification technique. Empirical implications of the two models are identified and it is argued that one should confront these with experimentally generated data in order to discriminate between the models. One reason for this is that historical data on abatement efforts in a global climate agreement do not exist since no such agreement has entered into force yet. (Author)

  1. Repeated Reticulate Evolution in North American Papilio machaon Group Swallowtail Butterflies.

    Julian R Dupuis

    Full Text Available Hybridization between distinct populations or species is increasingly recognized as an important process for generating biodiversity. However, the interaction between hybridization and speciation is complex, and the diverse evolutionary outcomes of hybridization are difficult to differentiate. Here we characterize potential hybridization in a species group of swallowtail butterflies using microsatellites, DNA sequences, and morphology, and assess whether adaptive introgression or homoploid hybrid speciation was the primary process leading to each putative hybrid lineage. Four geographically separated hybrid populations were identified in the Papilio machaon species group. One distinct mitochondrial DNA clade from P. machaon was fixed in three hybrid taxa (P. brevicauda, P. joanae, and P. m. kahli, while one hybrid swarm (P. zelicaon x machaon exhibited this hybrid mtDNA clade as well as widespread parental mtDNA haplotypes from both parental species. Microsatellite markers and morphology showed variable admixture and intermediacy, ranging from signatures of prolonged differential introgression from the paternal species (P. polyxenes/P. zelicaon to current gene flow with both parental species. Divergences of the hybrid lineages dated to early- to mid-Pleistocene, suggesting that repeated glaciations and subsequent range shifts of parental species, particularly P. machaon hudsonianus, facilitated initial hybridization. Although each lineage is distinct, P. joanae is the only taxon with sufficient evidence (ecological separation from parental species to define it as a homoploid hybrid species. The repetition of hybridization in this group provides a valuable foundation for future research on hybridization, and these results emphasize the potential for hybridization to drive speciation in diverse ways.

    To date, there is a lack of satisfactory inferential techniques for the analysis of multivariate data in factorial designs, when only minimal assumptions on the data can be made. Presently available methods are limited to very particular study designs or assume either multivariate normality or equal covariance matrices across groups, or they do not allow for an assessment of the interaction effects across within-subjects and between-subjects variables. We propose and methodologically validate a parametric bootstrap approach that does not suffer from any of the above limitations, and thus provides a rather general and comprehensive methodological route to inference for multivariate and repeated measures data. As an example application, we consider data from two different Alzheimer's disease (AD) examination modalities that may be used for precise and early diagnosis, namely, single-photon emission computed tomography (SPECT) and electroencephalogram (EEG). These data violate the assumptions of classical multivariate methods, and indeed classical methods would not have yielded the same conclusions with regards to some of the factors involved.

    K-means clustering has become a popular tool for connectivity-based cortical segmentation using Diffusion Weighted Imaging (DWI) data. A sometimes ignored issue is, however, that the output of the algorithm depends on the initial placement of starting points, and that different sets of starting points therefore could lead to different solutions. In this study we explore this issue. We apply k-means clustering a thousand times to the same DWI dataset collected in 10 individuals to segment two brain regions: the SMA-preSMA on the medial wall, and the insula. At the level of single subjects, we found that in both brain regions, repeatedly applying k-means indeed often leads to a variety of rather different cortical based parcellations. By assessing the similarity and frequency of these different solutions, we show that approximately 256 k-means repetitions are needed to accurately estimate the distribution of possible solutions. Using nonparametric group statistics, we then propose a method to employ the variability of clustering solutions to assess the reliability with which certain voxels can be attributed to a particular cluster. In addition, we show that the proportion of voxels that can be attributed significantly to either cluster in the SMA and preSMA is relatively higher than in the insula and discuss how this difference may relate to differences in the anatomy of these regions.

    Group B streptococcus (GBS) can cause severe disease in susceptible hosts, including newborns, pregnant women, and the elderly. GBS serine-rich repeat (Srr) surface glycoproteins are important adhesins/invasins in multiple host tissues, including the vagina. However, exact molecular mechanisms contributing to their importance in colonization are unknown. We have recently determined that Srr proteins contain a fibrinogen-binding region (BR) and hypothesize that Srr-mediated fibrinogen binding may contribute to GBS cervicovaginal colonization. In this study, we observed that fibrinogen enhanced wild-type GBS attachment to cervical and vaginal epithelium, and that this was dependent on Srr1. Moreover, purified Srr1-BR peptide bound directly to host cells, and peptide administration in vivo reduced GBS recovery from the vaginal tract. Furthermore, a GBS mutant strain lacking only the Srr1 "latching" domain exhibited decreased adherence in vitro and decreased persistence in a mouse model of GBS vaginal colonization, suggesting the importance of Srr-fibrinogen interactions in the female reproductive tract. © The Author 2014.

    As in most countries of the world also at Kosovo the rate of Cesarean section from year to year is increasing. The main purpose of this paper was to present the incidence of births completed by Caesarean section at the Clinic of Gynecology and Obstetrics of University Clinical Center of Kosovo in Prishtinë. This study is retrospective, namely its made by collecting epidemiological data from patients' histories that completed birth by Caesarean section for the period 2000-2006 in this clinic. During this period, 14 maternal deaths were recorded during or after Caesarean section. Besides this, 14 lethal outcomes, the object of our study was 84 mothers which completed birth by Caesarean section and which are best used as a control group. The average age of mothers who died during or after Caesarean section was 32.1 years (SD ± 4.9). Youngest in this group was 24 years old and oldest 42 years. While the average age of mothers from the control group was 30.6 years (SD ± 5.9). Youngest was 19 and oldest 43 years, without significant difference. Most mothers included in the survey had more than one indication for Caesarean section. The most frequent indication was PIH syndrome with 33.7% and previous Caesarean section in 32.7%. Then with the participation of 12.2% were abruption of the placenta and disproportio feto pelvinea, 11.2% pelvinea and placenta praevia presentation, 10.2% parturiens while other indications were much rarer with less than 10% participation. Based on this we can conclude that the risk of the Caesarean section is high.

  7. Vaginal Birth After Caesarean Section in Low Resource Settings: The Clinical and Ethical Dilemma.

    2015-10-01

    Vaginal birth after Caesarean section (VBAC) has long been practised in low resource settings using unconventional methods. This not only poses danger to the woman and her baby, but could also have serious legal and ethical implications. The adoption of this practice has been informed by observational studies with many deficiencies; this is so despite other studies from settings in which the standard of care is much better that show that elective repeat Caesarean section (ERCS) may actually be safer than VBAC. This raises questions about whether we should insist on a dangerous practice when there are safer alternatives. We highlight some of the challenges faced in making this decision, and discuss why the fear of ERCS may not be justified after all in low resource settings. Since a reduction in rates of Caesarean section may not be applicable in these regions, because their rates are already low, the emphasis should instead be on adequate birth spacing and safer primary operative delivery.

    To compare the results of isobaric bupivacaine (0.5%) with hyperbaric bupivacaine (0.75%) in cases of elective Caesarean Section, in respect of time to sensory analgesia, highest level of sensory block, haemodynamic effects, and complications. Sixty pregnant patients scheduled for elective Caesarean Section. The patients were randomly assigned to receive either 0.5% isobaric bupivacaine (Group-1B) or 0.75% hyperbaric bupivacaine (Group-HB) via intrathecal route. The time of onset of block, highest level of sensory block, cardio-respiratory data, duration of analgesia and complications were recorded during surgery. The time taken to reach T4 sensory analgesia in Group-1B was 6+-6.43 minutes as compared to 6.93+-7.8 minutes in Group-HB, while the highest sensory level achieved in Group-1B was T1 and in Group-HB T2. The lowest systolic blood pressure recorded in Group-1B was 83.27+-12.69 mmHg and in Group-HB 114.33+-13.83 mm Hg, the difference being significant (p<0.05). There was a higher incidence of complications in Group-1B as compared to Group-HB like high spinal analgesia, vomiting and discomfort. Intrathecal block showed a greater reduction in the systolic blood pressure, and associated complications, with Isobaric Bupivacaine as compared to Hyperbaric Bupivacaine. (author)

    The purpose of this study was to provide information to develop a program to prevent repeated falls by analyzing the difference in gait, muscle strength, balance, and fear of falling according to their fall experience. The study subjects were 110 elderly individuals aged over 60 years who agreed to their participation in this research. The study participants were categorized into a repeated fall group (n = 40), a one-time fall group (n = 15), and a nonfall group (n = 46) of the elderly.

    External cephalic version (ECV) in the presence of a uterine scar is still considered a relative contraindication despite encouraging studies of the efficacy and safety of this procedure. We present our experience with this patient population, which is the largest cohort published to date. To evaluate the efficacy and safety of ECV in the setting of a prior caesarean delivery. A total of 158 patients with a fetus presenting as breech, who had an unscarred uterus, had an ECV performed. Similarly, 158 patients with a fetus presenting as breech, and who had undergone a prior caesarean delivery also underwent an ECV. Outcomes were compared. ECV was successfully performed in 136/158 (86.1%) patients in the control group. Of these patients, 6/136 (4.4%) delivered by caesarean delivery. In the study group, 117/158 (74.1%) patients had a successful ECV performed. Of these patients, 12/117 (10.3%) delivered by caesarean delivery. There were no significant complications in either of the groups. ECV may be successfully performed in patients with a previous caesarean delivery. It is associated with a high success rate, and is not associated with an increase in complications. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Perinatal health disparities including disparities in caesarean births have been observed between migrant and non-migrant women and some literature suggests that non-medical factors may be implicated. A systematic review was conducted to determine if migrants in Western industrialized countries consistently have different rates of caesarean than receiving-country-born women and to identify the reasons that explain these differences. Reports were identified by searching 12 literature databases (from inception to January 2012; no language limits) and the web, by bibliographic citation hand-searches and through key informants. Studies that compared caesarean rates between international migrants and non-migrants living in industrialized countries and that did not have a 'fatal flaw' according to the US Preventative Services Task Force criteria were included. Studies were summarized, analyzed descriptively and where possible, meta-analyzed. Seventy-six studies met inclusion criteria. Caesarean rates between migrants and non-migrants differed in 69% of studies. Meta-analyses revealed consistently higher overall caesarean rates for Sub-Saharan African, Somali and South Asian women; higher emergency rates for North African/West Asian and Latin American women; and lower overall rates for Eastern European and Vietnamese women. Evidence to explain the consistently different rates was limited. Frequently postulated risk factors for caesarean included: language/communication barriers, low SES, poor maternal health, GDM/high BMI, feto-pelvic disproportion, and inadequate prenatal care. Suggested protective factors included: a healthy immigrant effect, preference for a vaginal birth, a healthier lifestyle, younger mothers and the use of fewer interventions during childbirth. Certain groups of international migrants consistently have different caesarean rates than receiving-country-born women. There is insufficient evidence to explain the observed differences.

    . These inequalities might be due to a combination of inadequate access to emergency obstetric care among the poorest subgroups and high levels of caesarean use without medical indication in the richest subgroups, especially in middle income countries. Country specific strategies should address these inequalities to improve maternal and newborn health. Published by the BMJ Publishing Group Limited.

    To quantify the association between maternal obesity and caesarean delivery, particularly caesarean delivery on maternal request (CDMR), a fast-growing component of caesarean delivery in many nations. We followed 1,019,576 nulliparous women registered in the Perinatal Healthcare Surveillance System during 1993-2010. Maternal body mass index (BMI, kg/m(2) ), before pregnancy or during early pregnancy, was classified as underweight (obese (≥27.5), consistent with World Health Organization guidelines for Asian people. The association between maternal obesity and overall caesarean and its subtypes was modelled using log-binomial regression. During the 18-year period, 404,971 (39.7%) caesareans and 93,927 (9.2%) CDMRs were identified. Maternal obesity was positively associated with overall caesarean and CDMR. Adjusted risk ratios for overall caesarean in the four ascending BMI categories were 0.96 [95% confidence interval (CI) 0.94, 0.97], 1.00 (Reference), 1.16 [95% CI 1.14, 1.18], 1.39 [95% CI 1.43, 1.54], and for CDMR were 0.95 [95% CI 0.94, 0.96], 1.00 (Reference), 1.20 [95% CI 1.18, 1.22], 1.48 [95% CI 1.433, 1.54]. Positive associations were consistently found in women residing in southern and northern provinces and in subgroups stratified by year of delivery, urban or rural residence, maternal age, education, level of delivering hospital, and birthweight. In a large Chinese cohort study, maternal obesity was associated with an increased risk of caesarean delivery and its subtypes, including CDMR. Given the rising global prevalence of obesity, and in view of the growth of CDMR, it seems likely that caesarean births will increase, unless there are changes in obstetrical practice. © 2015 John Wiley & Sons Ltd.

    Conclusions: As observed in this study, most pregnant women with previous caesarean delivery prefer repeated caesarean delivery rather than VD in their subsequent pregnancy and educational level of pregnant women and doctor′s advice were important factors that influenced this preference. This subject suggests the need to counsel pregnant women with an obstetrician before select delivery type.

  3. Techniques for assisting difficult delivery at caesarean section.

    Caesarean section involves making an incision in the woman's abdomen and cutting through the uterine muscle. The baby is then delivered through that incision. Difficult caesarean birth may result in injury for the infant or complications for the mother. Methods to assist with delivery include vacuum or forceps extraction or manual delivery utilising fundal pressure. Medication that relaxes the uterus (tocolytic medication) may facilitate the birth of the baby at caesarean section. Delivery of the impacted head after prolonged obstructed labour can be associated with significant maternal and neonatal complication; to facilitate delivery of the head the surgeon may utilise either reverse breech extraction or head pushing. To compare the use of tocolysis (routine or selective use) with no use of tocolysis or placebo and to compare different extraction methods at the time of caesarean section for outcomes of infant birth trauma, maternal complications (particularly postpartum haemorrhage requiring blood transfusion), and long-term measures of infant and childhood morbidity. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2015) and reference lists of retrieved studies. All published, unpublished, and ongoing randomised controlled trials comparing the use of tocolytic agents (routine or selective) at caesarean section versus no use of tocolytic or placebo at caesarean section to facilitate the birth of the baby. Use of instrument versus manual delivery to facilitate birth of the baby. Reverse breech extraction versus head pushing to facilitate delivery of the deeply impacted fetal head. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. Seven randomised controlled trials, involving 582 women undergoing caesarean section were included in this review. The risk of bias of included trials was variable, with some trials not adequately describing allocation or

    Articaine is used as a local anesthetic for outpatient surgery because it offers rapid onset of anesthesia and short duration motor block. Levobupivacaine is often preferred for Caesarean section. We evaluated the anesthetic characteristics of fentanyl-supplemented plain articaine and levobupivacaine for Caesarean section under combine spinal epidural anesthesia. Patients undergoing Caesarean section received in random order plain articaine 40 mg (Group A, n=50) or plain levobupivacaine 10 mg (Group L, n=50) mixed with fentanyl 20 µg intrathecally. The onset and duration of sensory and motor block, first analgesic request, and hemodynamic parameters were recorded. Onset times of maximum motor block were longer in Group L than Group A (P=0,001). Time to two-segment regression of sensory block were 70 min for Group A and 90 min group L (P=0.001). Times to complete regression of motor blockade were significantly longer in group L than group A (P =0,001). To have a faster onset and shorter duration of spinal anesthesia, we recommend the use of plain articaine for Caesarean section.

  11. Methods of achieving and maintaining an appropriate caesarean section rate.

    LENUS (Irish Health Repository)

    2013-04-01

    Caesarean section rates continue to increase worldwide. The appropriate caesarean section rate remains a topic of debate among women and professionals. Evidence-based medicine has not provided an answer and depends on interpretation of the literature. Overall caesarean section rates are unhelpful, and caesarean section rates should not be judged in isolation from other outcomes and epidemiological characteristics. Better understanding of caesarean section rates, their consequences and their benefits will improve care, and enable learning between delivery units nationally and internationally. To achieve and maintain an appropriate caesarean section rate requires a Multidisciplinary Quality Assurance Programme in each delivery unit, recognising caesarean section rates as one of many factors that determine quality. Women will always choose the type of delivery that seems safest to them and their babies. Professionals need to monitor the quality of their practice continuously in a standardised way to ensure that women can make the right choice.

    2010-12-01

    Full Text Available Abstract Background Rates of caesarean section are progressively increasing in many parts of the world. As a result of psychosocial factors there has been an increasing tendency for pregnant women without justifiable medical indications for caesarean section to ask for this procedure in China. A critical examination of this issue in relation to maternal outcomes is important. At present there are no clinical trials to help assess the risks and benefits of caesarean section in low risk women. To fill the gap left by trials, this indication-matched cohort study was carried out to examine prospectively the outcomes of caesarean section on women with no absolute obstetric indication compared with similar women who had vaginal delivery. Methods An indication-matched cohort study was undertaken to compare maternal outcomes following caesarean section with those undergoing vaginal delivery, in which the two groups were matched for non-absolute indications. 301 nulliparous women with caesarean section were matched successfully with 301 women who delivered vaginally in the Maternal and Children's Hospitals (MCHs in Shanghai, China. Logistic regression model or binomial regression model was used to estimate the relative risk (RR directly. Adjusted RRs were calculated adjusting for propensity score and medical indications. Results The incidence of total complications was 2.2 times higher in the caesarean section group during hospitalization post-partum, compared with the vaginal delivery group (RR = 2.2; 95% CI: 1.1-4.4. The risk of haemorrhage from the start of labour until 2 hours post-partum was significantly higher in the caesarean group (RR = 5.6; 95% CI: 1.2-26.9. The risk of chronic abdominal pain was significantly higher for the caesarean section group (RR = 3.6; 95% CI: 1.2-10.9 than for the vaginal delivery group within 12 months post-partum. The two groups had similar incidences of anaemia and complicating infections such as wound complications

    This study evaluated the effects of vaginal and caesarean delivery on internal and external anal sphincter muscle thickness using translabial ultrasonography (TL-US). This prospective cohort study enrolled nulliparous women who either had vaginal or caesarean deliveries. The thickness of the hypoechoic internal anal sphincter (IAS) and hyperechoic external anal sphincter (EAS) at the 12, 3, 6, and 9 o'clock positions at the distal level were measured before delivery and within 24-48 h after delivery. A total 105 consecutive women were enrolled in the study: 60 in the vaginal delivery group and 45 in the caesarean delivery group. The IAS muscle thickness at the 12 o'clock position in the vaginal delivery group was significantly thicker before compared with after delivery (mean ± SD: 2.31 ± 0.74 mm versus 1.81 ± 0.64 mm, respectively). The EAS muscle thickness at the 12 o'clock position in the vaginal delivery group was significantly thicker before compared with after delivery (mean ± SD: 2.42 ± 0.64 mm versus 1.97 ± 0.85, respectively). There was significant muscle thinning of both the IAS and EAS at the 12 o'clock position after vaginal delivery, but not after caesarean delivery. © The Author(s) 2016.

    A group version of the Trier Social Stress Test (TSST-G) was introduced as a standardized, economic and efficient tool to induce a psychobiological stress response simultaneously in a group of subjects. The aim of the present study was to examine the efficacy of the TSST-G to repeatedly induce an affective and autonomic stress response while comparing two alternative protocols for the second examination. Healthy young male recruits participated twice in the TSST-G 10 weeks apart. In the first examination, the TSST-G consisted of a combination of mental arithmetic and a fake job interview (TSST-G-1st; n=294). For the second examination, mental arithmetic was combined with either (a) a defensive speech in response to a false shoplifting accusation (TSST-G-2nd-defence; n=105), or (b) a speech on a more neutral topic selected by the investigators (TSST-G-2nd-presentation; n=100). Affect ratings and salivary alpha-amylase (sAA) were determined immediately before and after the stress test, while heart rate (HR) and heart rate variability (HRV) were measured continuously. TSST-G-1st resulted in a significant increase of negative affect, HR, and sAA, and a significant decrease in positive affect and HRV. TSST-G-2nd, overall, resulted in a significant increase of HR and sAA (the latter only in response to TSST-G-2nd-defence) and a decrease in HRV, while no significant affect alterations were found. When comparing both, TSST-G-2nd-defence and -2nd-presentation, the former resulted in a stronger stress response with regard to HR and HRV. The findings reveal that the TSST-G is a useful protocol to repeatedly evoke an affective and autonomic stress response, while repetition leads to affective but not necessarily autonomic habituation. When interested in examining repeated psychosocial stress reactivity, a task that requires an ego-involving effort, such as a defensive speech, seems to be significantly superior to a task using an impersonal speech.

    Objectives. We aimed to assess if Caesarean section is a risk factor for overnutrition in early- and late-childhood, and to assess the magnitude of the effect of child- versus family-related variables in these risk estimates. Methods. Longitudinal data from Peruvian children from the Young Lives Study was used. Outcomes assessed were overweight, obesity, overnutrition (overweight plus obesity), and central obesity (waist circumference) at the age 5 (first follow-up) and 7 (second follow-up) years. The exposure of interests was delivery by Caesarean section. Relative risks (RR) and 95% confidence intervals (95% CI) were calculated using multivariable models adjusted for child-related (e.g., birth weight) and family-related (e.g., maternal nutritional status) variables. Results. At baseline, mean age was 11.7 (± 3.5) months and 50.1% were boys. Children born by Caesarean section were 15.6%. The 10.5% of the children were overweight and 2.4% were obese. For the obesity outcome, data from 6,038 and 9,625 children-years was included from baseline to the first and second follow-up, respectively. Compared to those who did not experience Caesarean delivery, the risk of having obesity was higher in the group born by Caesarean: RRs were higher at early-childhood (first follow-up: 2.25; 95% CI [1.36-3.74]) than later in life (second follow-up: 1.57; 95% CI [1.02-2.41]). Family-related variables had a greater effect in attenuating the risk estimates for obesity at the first, than at the second follow-up. Conclusion. Our results suggest a higher probability of developing obesity, but not overweight, among children born by Caesarean section delivery. The magnitude of risk estimates decreased over time, and family-related variables had a stronger effect on the risk estimates at early-childhood.

    The United Kingdom (UK) caesarean section (CS) rate is largely determined by reluctance to augment trial of labour and vaginal birth. Choice between repeat CS and attempting vaginal birth after CS (VBAC) in the next pregnancy is challenging, with neither offering clear safety advantages. Women may access online information during the decision-making process. Such information is known to vary in its support for either mode of birth when assessed quantitatively. Therefore, we sought to explore qualitatively, the content and presentation of web-based health care information on birth after caesarean section (CS) in order to identify the dominant messages being conveyed. The search engine Google™ was used to conduct an internet search using terms relating to birth after CS. The ten most frequently returned websites meeting relevant purposive sampling criteria were analysed. Sampling criteria were based upon funding source, authorship and intended audience. Images and written textual content together with presence of links to additional media or external web content were analysed using descriptive and thematic analyses respectively. Ten websites were analysed: five funded by Government bodies or professional membership; one via charitable donations, and four funded commercially. All sites compared the advantages and disadvantages of both repeat CS and VBAC. Commercially funded websites favoured a question and answer format alongside images, 'pop-ups', social media forum links and hyperlinks to third-party sites. The relationship between the parent sites and those being linked to may not be readily apparent to users, risking perception of endorsement of either VBAC or repeat CS whether intended or otherwise. Websites affiliated with Government or health services presented referenced clinical information in a factual manner with podcasts of real life experiences. Many imply greater support for VBAC than repeat CS although this was predominantly conveyed through subtle

    Pregnancy in women with achondroplasia presents major challenges for anaesthetists and obstetricians. We report the case of a woman with achondroplasia who underwent general anaesthesia for an elective caesarean section. She was 99cm in height and her condition was further complicated by severe kyphoscoliosis and previous back surgery. She was reviewed in the first trimester at the anaesthetic high-risk clinic. A multidisciplinary team was convened to plan her peripartum care. Because of increasing dyspnoea caesarean section was performed at 32weeks of gestation. She received a general anaesthetic using a modified rapid-sequence technique with remifentanil and rocuronium. The intraoperative period was complicated by desaturation and high airway pressures. The woman's postoperative care was complicated by respiratory compromise requiring high dependency care. Copyright © 2014 Elsevier Ltd. All rights reserved.

  19. Perimortem caesarean section following maternal gunshot wounds

    Directory of Open Access Journals (Sweden)

    2011-01-01

    Full Text Available Perimortem caesarean section is an ethically difficult decision for emergency medicine resuscitation teams. A 34-years-old woman was attacked by her husband with a gunshot. At the time arrival to the emergency room, there was no pulse, no spontaneous breath and blood pressure was unobtainable. Although extensive advanced cardiopulmonary resuscita-tion was performed for 7 minutes, no cardiac activity was regained. During the cardiopulmonary resuscitation efforts, an abdominal ultrasonography was performed and revealed a fetal heart rate with bradycardia. Low segment caesarean section was performed by the obstetrician in the resuscitation room and a female newborn was delivered within less than one minute of the skin incision. Decision on terminating the CPR efforts should not be made in maternal cardiac arrests older than 28 weeks′ gestational age, unless the viability of the fetus had been evaluated.

    The narrative of caesarean birth appears on several occasions in Greek mythology: in the birth of Dionysus is the God of the grape harvest and winemaking and wine; in the birth of Asclepius the God of medicine and healing; and in the birth of Adonis the God of beauty and desire. It is possible, however not obligatory, that it was not solely a fantasy but also reflected a contemporary medical practice.

    Full Text Available Adequate post-operative analgesia after caesarean section (CS is vital as it impacts the distinct surgical recovery requirements of the parturient. Although newer analgesic modalities and drugs for post-caesarean analgesia have been introduced over the recent years, review of the literature suggests suggests that we are far from achieving the goals of optimum post-operative analgesia. We conducted a systematic review of recent advances in modalities for post-caesarean analgesia. After systematic search and quality assessment of studies, we included a total of 51 randomised controlled trials that evaluated the role of opioids, transversus abdominis plane (TAP block, wound infiltration/infusion, ketamine, gabapentin and ilioinguinal-iliohypogastric nerve block (II-IH NB for post-caesarean analgesia. Administration of opioids still remains the gold standard for post-operative analgesia, but the associated troublesome side effects have led to the mandatory incorporation of non-opioid analgesics in post-CS analgesia regime. Among the non-opioid techniques, TAP block is the most investigated modality of the last decade. The analgesic efficacy of TAP block as a part of multimodal analgesia is established in post-CS cases where intrathecal morphine is not employed and in CS under general anaesthesia. Among non-steroidal anti-inflammatory drugs, COX-I inhibitors and intravenous paracetamol are found to be useful in post-operative analgesic regimen. The perioperative use of ketamine is found useful only in CS done under spinal anaesthesia; no benefit is seen where general anaesthesia is employed. Wound infiltration with local anaesthetics, systemic gabapentin and II-IH NB need further trials to assess their efficacy.

    Full Text Available Background. Pain after Caesarean delivery is partly related to Pfannenstiel incision, which can be infiltrated with local anaesthetic solutions. Methods. A double- blind randomized control trial was designed to assess the analgesic efficacy of 7.5 mg/mL ropivacaine solution compared to control group, in two groups of one hundred and forty four parturients for each group, who underwent Caesarean section under spinal anaesthesia: group R (ropivacaine group and group C (control group. All parturients also received spinal sufentanil (2.5 g. Results. Ropivacaine infiltration in the Pfannenstiel incision for Caesarean delivery before wound closure leads to a reduction of 30% in the overall consumption of analgesics (348 550 mg for group R versus 504 426 mg for group C with <.05, especially opioids in the first 24 hours, but also significantly increases the time interval until the first request for an analgesic (4 h 20 min ± 2 h 26 for group R versus 2 h 42 ± 1 h 30 for group C. The P values for the two groups were: <.0001 for paracetamol, <.0001 for ketoprofen and P for nalbuphine which was the most significant. There is no significant difference in the threshold of VAS in the two series. Conclusion. This technique can contribute towards a programme of early rehabilitation in sectioned mothers, with earlier discharge from the post-labour suite.

    Clustered regularly interspaced short palindromic repeats (CRISPR) are the bacterial adaptive immune system against foreign nucleic acids. Given the variable nature of CRISPR, it could be a good marker for molecular epidemiology. Group A streptococcus is one of the major human pathogens. It has two CRISPR loci, including CRISPR01 and CRISPR02. The aim of this study was to analyze the distribution of CRISPR-associated gene cassettes (cas) and CRISPR arrays in highly prevalent emm types. The cas cassette and CRISPR array in two CRISPR loci were analyzed in a total of 332 strains, including emm1, emm3, emm4, emm12, and emm28 strains. The CRISPR type was defined by the spacer content of each CRISPR array. All strains had at least one cas cassette or CRISPR array. More than 90% of the spacers were found in one emm type, specifically. Comparing the consistency between emm and CRISPR types by Simpson's index of diversity and the adjusted Wallace coefficient, CRISPR01 type was concordant to emm type, and CRISPR02 showed unidirectional congruence to emm type, suggesting that at least for the majority of isolates causing infection in high income countries, the emm type can be inferred from CRISPR analysis, which can further discriminate isolates sharing the same emm type.

    In neuropsychological research, single-cases are often compared with a small control sample. Crawford and colleagues developed inferential methods (i.e., the modified t-test) for such a research design. In the present article, we suggest an extension of the methods of Crawford and colleagues employing linear mixed models (LMM). We first show that a t-test for the significance of a dummy coded predictor variable in a linear regression is equivalent to the modified t-test of Crawford and colleagues. As an extension to this idea, we then generalized the modified t-test to repeated measures data by using LMMs to compare the performance difference in two conditions observed in a single participant to that of a small control group. The performance of LMMs regarding Type I error rates and statistical power were tested based on Monte-Carlo simulations. We found that starting with about 15-20 participants in the control sample Type I error rates were close to the nominal Type I error rate using the Satterthwaite approximation for the degrees of freedom. Moreover, statistical power was acceptable. Therefore, we conclude that LMMs can be applied successfully to statistically evaluate performance differences between a single-case and a control sample.

    The purpose of our study was to evaluate the safety and efficacy of transcervical amnioinfusion during labour complicated by meconium-stained amniotic fluid, in a setting with limited peripartum facilities, to lower the incidence of caesarean section. A prospective study was conducted in a teaching hospital in north India, which enrolled 292 patients admitted in labour. Patients were randomly divided into two groups after taking their consent. One group received transcervical amnioinfusion, whilst in the other group amnioinfusion was not done. Caesarean sections were performed in either group if there were foetal heart rate abnormalities (bradycardia or irregularity for 10-20 min) or slow progress of labour. The outcomes studied were the incidence of caesarean sections, duration of maternal hospital stay, maternal febrile morbidity (temperature of >38 degrees C, 24 h after delivery), low Apgar score (at 1 and 5 min), respiratory death, MAS and perinatal mortality. There was a statistically significant reduction in the incidence of caesarean sections in the study group compared to the control group (31 vs. 61%). Amnioinfusion was associated with improved neonatal outcome as evidenced by statistically improved Apgar score at 1 min in newborns in the study group compared to the control group (10 vs. 37.2%). Amnioinfusion during labour was not associated with any significant maternal and neonatal complications. The mean hospital stay of the mother was decreased significantly in the study group patients compared to the control group. Transcervical amnioinfusion in labour for meconium-stained amniotic fluid is a simple, safe and easy-to-perform procedure. It can be performed safely in a setup with limited peripartum facilities, especially in developing countries, to decrease intrapartum operative intervention and reduce foetomaternal morbidity and mortality.

    The optimal mode of subsequent delivery of women with prior caesarean birth remains a subject of intense research and debate in contemporary obstetric practice especially in low resource settings like West Africa where there are obvious systemic and management-related challenges associated with trial of scar. However, there is evidence that vaginal birth after caesarean section (VBAC) is safe in appropriately selected women in addition to adequate intrapartum monitoring and ready access to theatre when emergency CS is indicated. The primary objective of the study was to determine the current trends and performance of VBAC in Ghana after decades of practice of trial of labour after caesarean section (TOLAC) in the mist of inherent challenges in deciding the optimal mode of childbirth for women with a previous caesarean birth. The secondary objective was to relate evidence based practice of TOLAC to obstetric practice in low resource settings like Ghana and provide recommendations for improving maternal and newborn health among women with prior caesarean birth. This was a retrospective study of the records of patients who had had a prior caesarean delivery and who then proceeded to deliver the next babies at the Korle Bu Teaching Hospital (KBTH) between Jan 2010 and Dec 2014. The data on demography, antenatal care, labour and delivery and outcomes were collected from the Labour and Recovery wards and the Biostatistics unit of the Maternity unit of the Hospital. Excluded were women with a previous CS who had multiple pregnancies and those with incomplete notes as well as those whose delivery plans were not predetermined antenatally.. The data were analyzed using SPSS version 20. There were 53,581 deliveries during the study period. Vaginal delivery was obtained in 31,870 (59.5%) pregnancies and 21,711(40.5%) had CS. Also, 6261 (11.7%) had had a prior CS and 2472 (39.5%) of these were selected for TOLAC while 2119 (33.8) were scheduled for planned repeat CS. There was

    Thromboprophylaxis for women undergoing caesarean section (CS) was introduced in the hospital in 1995. This study audited the use of tinzaparin prophylaxis in a nested cohort of women who screened negative for diabetes mellitus at 28 weeks gestation. All the women had their weight measured and BMI calculated at the first antenatal visit. Of the 284 women, 68 (24%) had a CS and all received tinzaparin. Of the 68, however, 94% received a dose lower than recommended. Compliance with prophylaxis was complete but compliance with the recommended dosage was suboptimal, which may result in venous thromboembolism after CS despite thromboprophylaxis.

    Full Text Available Background: Caesarean section has been a part of human culture since ancient times. It has been used effectively throughout the 20th century and among the major abdominal surgeries, it is the most common, oldest worldwide surgery performed in obstetrics. Despite the life saving advantages, there are several adverse consequences of caesarean delivery for a woman and to her household. The rate and risk of these complications increases due to the increasing incidence mainly in countries like India. The role of nurse midwife is to act in the best interest of patient and newborn and make the patient independent in carrying out the activities of daily living as soon as possible. This can lead to a faster recovery and shorter hospital stay. Also it can indirectly help in reducing the complications associated with prolonged bed rest and can improve the maternal newborn bonding. Aim and Objectives: The present study was done to evaluate the effect of planned early ambulation on selected biophysiological health parameters of post caesarean patients. Material and Methods: The study included total 500 study subjects, 250 in experimental and 250 in control group. Quasi experimental approach with multiple time series design was adopted for the study. The experimental group was given an early planned recommended ambulation technique starting from the day of surgery. This consisted of deep breathing exercise, cough exercise, leg exercise and early mobilization. Over and above, the routine general health care was given by the doctors and nurses. The control group received only by routine general care by doctors and nurses and mobilization on third post operative day as per strategy adopted by the hospital. The deep breathing exercises, coughing exercises and leg exercises were not given routinely and hence were not given to the control group. Post caesarean biophysiological parameters chart was used to assess the selected parameters for first five post operative

    Full Text Available Introduction: Association between caesarean section and intra operative and post operative bleeding is known. Post-partum hemorrhage is still a leading cause for maternal morbidity and mortality. This study will evaluate the efficacy and safety of tranexamic acid in reducing the blood loss after placental delivery following lower segment caesarean section (LSCS and note any adverse effects. Materials and Methods: A total of 100 women, who underwent elective or emergency primary caesarean section at term between 37 and 41 weeks have been studied prospectively. They were divided into two groups. In the study group of 50, tranexamic acid 1 gm IV was given 20 minutes before making incision for caesarean section and the control group of 50 did not receive tranexamic acid. Statistical Analysis: For quantitative outcomes, the t-test was used to test for difference in the two groups. For categorical outcomes, chi square and odds ratio with 95% confidence interval were used as applicable. Results: The patient characteristics, namely age, height, weight, gestational age and gravidity in two groups were similar which was statistically insignificant. Hemoglobin decreased slightly after birth in both groups but no statistical difference between two groups was noticed. There was no episode of thrombosis in the study. Tranexamic acid significantly reduced the quantity of the blood loss from time of placental delivery to 2 hours postpartum (P < 0.001 and from end of LSCS to 2 hours postpartum (P < 0.001. However, there was no statistical difference in quantity of blood loss from time of placental delivery to end of LSCS in both groups (P < 0.001. Conclusion: A safe dose of tranexamic acid has an effective role in reducing blood loss during LSCS without causing adverse reaction. Thus, drug can be used effectively in reducing maternal morbidity and mortality during LSCS.

    To study changes of renin-angiotensin-aldosterone system (RAAS) and influence of anesthetic effect on it during caesarean operation, PRA, AT II and ALD in maternal and placental blood were determined by RIA for 30 healthy women scheduled for caesarean operation. Blood was taken before anesthesia(T 0 group) and just at the end of surgery (T 1 group) for comparison. Results showed that there were significant differences in PRA(P 0 and T 1 group, but there were no significant differences in ALD, PRA and AT II between placental blood, umbilical arteria and vein blood. The data suggest that there was obvious relationship between anesthetic effect and the secretion of RAAS. The levels of AT II, ALD and PRA in patients of partial block anesthesia were significantly than those in patients of complete block anesthesia. (authors)

    To describe the challenges of, and steps taken to successfully collect video ethnographic data during and after caesarean sections. Video ethnographic research uses real-time video footage to study a cultural group or phenomenon in the natural environment. It allows researchers to discover previously undocumented practices, which in-turn provides insight into strengths and weaknesses in practice. This knowledge can be used to translate evidence-based interventions into practice. Video ethnographic design. A video ethnographic approach was used to observe the contact between mothers and babies immediately after elective caesarean sections in a tertiary hospital in Sydney, Australia. Women, their support people and staff participated in the study. Data were collected via video footage and field notes in the operating theatre, recovery and the postnatal ward. Challenges faced whilst conducting video ethnographic research included attaining ethics approval, recruiting vast numbers of staff members and 'vulnerable' pregnant women, and endeavouring to be a 'fly on the wall' and a 'complete observer'. There were disadvantages being an 'insider' whilst conducting the research because occasionally staff members requested help with clinical tasks whilst collecting data; however, it was an advantage as it enabled ease of access to the environment and staff members that were to be recruited. Despite the challenges, video ethnographic research enabled the provision of unique data that could not be attained by any other means. Video ethnographic data are beneficial as it provides exceptionally rich data for in-depth analysis of interactions between the environment, equipment and people in the hospital environment. The analysis of this type of data can then be used to inform improvements for future care. © 2016 John Wiley & Sons Ltd.

    PurposeTo explore the efficacy and safety of prophylactic temporary balloon occlusion of the infrarenal abdominal aorta during caesarean for the management of patients with placenta praevia accreta.MethodsTwo hundred and sixty-eight cases of placenta praevia accreta from January 2012 to June 2015 were retrospectively reviewed. Group A included two hundred and thirty patients who underwent prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section. Group B included thirty-eight patients who underwent caesarean without endovascular intervention. The parameters including operating room time, estimated blood loss, blood transfusion volume, PT (prothrombin time) during operation, days in the intensive care unit, and total hospital days were compared between the two groups.ResultsThe operating room time, estimated blood loss, PT, the incidence of hysterectomy, blood transfusion volume, postpartum haemorrhage, and days in intensive care unit were lower in group A than in group B, with statistical significance (P   0.05). No patient in the group with prophylactic temporary balloon occlusion of the infrarenal abdominal aorta was performed hysterectomy, while three patients in group B were performed hysterectomy because of uncontrollable haemorrhage.ConclusionsThe results indicate that prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section is safe and effective to control intraoperative blood loss and greatly decreases the risk of hysterectomy in patients with placenta praevia accreta.

    To determine the risks and benefits of an elective Caesarean section (CS) at term in healthy nulliparous women. We conducted a population-based cohort study of deliveries between 1994 and 2002. Using bivariate and multivariable techniques, we compared maternal and neonatal outcomes in healthy nulliparous women who had undergone elective pre-labour CS (using breech presentation as a surrogate) with those in women who had undergone spontaneous labour with anticipated vaginal delivery (SL) at full term. There were 1046 deliveries in the pre-labour CS group and 38 021 in the SL group. Life-threatening maternal morbidity was similar in each group. Life-threatening neonatal morbidity was decreased in the CS group (RR 0.34; 99% CI 0.12 to 0.97). Subgroup analysis of the SL group by mode of delivery demonstrated the increased neonatal risk was associated with operative vaginal delivery and intrapartum CS but not spontaneous vaginal delivery. An elective pre-labour Caesarean section in a nulliparous woman at full term decreased the risk of life-threatening neonatal morbidity compared with spontaneous labour with anticipated vaginal delivery. However, the 63% of women with spontaneous labour who achieved a spontaneous vaginal delivery would not have benefited from delivery by Caesarean section. Further research is needed to better identify women with an increased likelihood of an operative vaginal or intrapartum Caesarean section, as this may assist maternity caregivers in decision-making about childbirth. Further research is also needed to determine if these findings can be confirmed in a prospective study.

    To identify the role of bilateral internal iliac artery (IIA) ligation on reducing blood loss in abnormally invasive placenta (AIP) undergoing caesarean hysterectomy. In this parallel-randomized control trial, 57 pregnant females with ultrasound features suggestive of AIP were enrolled. They were randomized into two groups; IIA group (n = 29 cases) performed bilateral IIA ligation followed by caesarean hysterectomies, while Control group (n = 28 cases) underwent caesarean hysterectomy only. The main outcome was the difference in the estimated intraoperative blood loss between the two groups. There was no significant difference between the two groups regarding the intraoperative estimated blood loss (1632 ± 804 versus 1698 ± 1251, p value .83). The operative procedure duration (minutes) (223 ± 66 versus 171 ± 41.4, p value .001) varied significantly between the two groups. Bilateral internal iliac artery ligation, in cases of AIP undergoing caesarean hysterectomy, is not recommended for routine practice to minimize blood loss intraoperatively.

    High caesarean rates are of concern given associated risks. International migrant women (women born abroad) represent a substantial proportion of women giving birth in high-income countries (HICs) and face social conditions that may exacerbate childbearing health risks. Among migrant women, emergency rather than planned caesareans, tend to be more prevalent. This method of delivery can be stressful, physically harmful and result in an overall negative birth experience. Research establishing evidence of risk factors for emergency caesareans in migrants is insufficient. (1) Describe potential pathways (with a focus on modifiable factors) by which migration, using internationally recommended migration indicators: country of birth, length of time in country, fluency in receiving-country language, migration classification and ethnicity, may lead to emergency caesarean; and (2) propose a framework to guide future research for understanding "potentially preventable" emergency caesareans in migrant women living in HICs. "Potentially preventable" emergency caesareans in migrant women are likely due to several modifiable, interrelated factors pre-pregnancy, during pregnancy and during labour. Migration itself is a determinant and also shapes other determinants. Complications and ineffective labour progress and/or foetal distress and ultimately the decision to perform an emergency caesarean may be the result of poor health (i.e., physiological effects), lack of support and disempowerment (i.e., psychological effects) and sub-optimal care. Understanding the direct and indirect effects of migration on emergency caesarean is crucial so that targeted strategies can be developed and implemented for reducing unnecessary caesareans in this vulnerable population.

    Full Text Available Abstract Background Caesarean section (CS rates around the world have been increasing and in Australia have reached 30% of all births. Robson's Ten-Group Classification System (10-group classification provides a clinically relevant classification of CS rates that provides a useful basis for international comparisons and trend analyses. This study aimed to investigate trends in CS rates in New South Wales (NSW, including trends in the components of the 10-group classification. Methods We undertook a cross-sectional study using data from the Midwives Data Collection, a state-wide surveillance system that monitors patterns of pregnancy care, services and pregnancy outcomes in New South Wales, Australia. The study population included all women giving birth between 1st January 1998 and 31st December 2008. Descriptive statistics are presented including age-standardised CS rates, annual percentage change as well as regression analyses. Results From 1998 to 2008 the CS rate in NSW increased from 19.1 to 29.5 per 100 births. There was a significant average annual increase in primary 4.3% (95%CI 3.0-5.7% and repeat 4.8% (95% CI 3.9-5.7% CS rates from 1998 to 2008. After adjusting for maternal and pregnancy factors, the increase in CS delivery over time was maintained. When examining CS rates classified according to the 10-group classification, the greatest contributors to the overall CS rate and the largest annual increases occurred among nulliparae at term having elective CS and multipara having elective repeat CS. Conclusions Given that the increased CS rate cannot be explained by known and collected maternal or pregnancy characteristics, the increase may be related to differences in clinical decision making or maternal request. Future efforts to reduce the overall CS rate should be focussed on reducing the primary CS rate.

    Full Text Available BACKGROUND Recently, caesarean section rates are increased in developing countries like India. Postpartum haemorrhage is more after caesarean section. Most of the maternal mortality is attributed to postpartum haemorrhage. This study was undertaken to find out the drug effective in reducing blood loss in lower segment caesarean section. The aim of the study is to compare the efficacy of ethamsylate versus tranexamic acid in reducing blood loss during and after caesarean section. MATERIALS AND METHODS All women undergoing LSCS were divided in 3 groups, viz. 2 study groups and control group. All were requested for preop and postop Hb%, PCV and TRBC. Tranexamic acid and ethamsylate, 1 g diluted in 10 mL NS were given intravenously for both the study groups and control group with NS, 20 minutes prior to skin incision and blood loss was measured from placental delivery up to 2 hours in all the groups was calculated by weighing pre-weighted pads soaked in blood. RESULTS Statistical analysis was done quantitatively by Student’s t-test. Postoperative blood loss was similar and lower in both the study groups compared to the control group. Hb% change in postop period is significant in control group. CONCLUSION Ethamsylate is safe and effective alternative to tranexamic acid in preventing postpartum haemorrhage after caesarean section.

    Preterm delivery is often performed by Caesarean section. We investigated modes of anaesthesia and risk factors for general anaesthesia among women undergoing preterm Caesarean delivery. Women undergoing Caesarean delivery between 24(+0) and 36(+6) weeks' gestation were identified from a multicentre US registry. The mode of anaesthesia was classified as neuraxial anaesthesia (spinal, epidural, or combined spinal and epidural) or general anaesthesia. Logistic regression was used to identify patient characteristic, obstetric, and peripartum risk factors associated with general anaesthesia. Within the study cohort, 11 539 women had preterm Caesarean delivery; 9510 (82.4%) underwent neuraxial anaesthesia and 2029 (17.6%) general anaesthesia. In our multivariate model, African-American race [adjusted odds ratio (aOR)=1.9; 95% confidence interval (CI)=1.7-2.2], Hispanic ethnicity (aOR=1.5; 95% CI=1.2-1.8), other race (aOR=1.4; 95% CI=1.1-1.9), and haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome or eclampsia (aOR=2.8; 95% CI=2.2-3.5) were independently associated with receiving general anaesthesia for preterm Caesarean delivery. Women with an emergency Caesarean delivery indication had the highest odds for general anaesthesia (aOR=3.5; 95% CI=3.1-3.9). For every 1 week decrease in gestational age at delivery, the adjusted odds of general anaesthesia increased by 13%. In our study cohort, nearly one in five women received general anaesthesia for preterm Caesarean delivery. Although potential confounding by unmeasured factors cannot be excluded, our findings suggest that early gestational age at delivery, emergent Caesarean delivery indications, hypertensive disease, and non-Caucasian race or ethnicity are associated with general anaesthesia for preterm Caesarean delivery. © The Author 2015.

    Full Text Available Objectives. We aimed to assess if Caesarean section is a risk factor for overnutrition in early- and late-childhood, and to assess the magnitude of the effect of child- versus family-related variables in these risk estimates.Methods. Longitudinal data from Peruvian children from the Young Lives Study was used. Outcomes assessed were overweight, obesity, overnutrition (overweight plus obesity, and central obesity (waist circumference at the age 5 (first follow-up and 7 (second follow-up years. The exposure of interests was delivery by Caesarean section. Relative risks (RR and 95% confidence intervals (95% CI were calculated using multivariable models adjusted for child-related (e.g., birth weight and family-related (e.g., maternal nutritional status variables.Results. At baseline, mean age was 11.7 (± 3.5 months and 50.1% were boys. Children born by Caesarean section were 15.6%. The 10.5% of the children were overweight and 2.4% were obese. For the obesity outcome, data from 6,038 and 9,625 children-years was included from baseline to the first and second follow-up, respectively. Compared to those who did not experience Caesarean delivery, the risk of having obesity was higher in the group born by Caesarean: RRs were higher at early-childhood (first follow-up: 2.25; 95% CI [1.36–3.74] than later in life (second follow-up: 1.57; 95% CI [1.02–2.41]. Family-related variables had a greater effect in attenuating the risk estimates for obesity at the first, than at the second follow-up.Conclusion. Our results suggest a higher probability of developing obesity, but not overweight, among children born by Caesarean section delivery. The magnitude of risk estimates decreased over time, and family-related variables had a stronger effect on the risk estimates at early-childhood.

    2015-05-01

    The aim of the study was to compare the effectiveness of Carbetocin versus Oxyotcin during caesarean section for preventing postpartum haemorrhage. Prospective observational study (before/after design). Five hundred and forty patients who received an injection of Oxytocin were compared to 262 patients with single injection of 100 micrograms of Carbetocin. The primary outcome was to compare the differential hematocrit level between pre- and postoperative blood samples. The secondary outcome was to compare differential hemoglobin level and the use of complementary therapies for postpartum haemorrhage. We did not find any difference between the Oxytocin and Carbetocin groups on differential hematocrit level. There was no difference between the groups regarding the use of additionnal therapies (Sulproston injections, blood transfusions and surgery methods). The rate of postpartum haemorrhage was similar in the two groups (18.7% vs 21.6%; P=0.33). We found a lower percentage of patients with differential of hemoglobin level between 2 g/dL and 4 g/dL in the Carbetocin group (6.5% vs 15.6%, Poxytocin. Carbetocin seems to reduce the need for postoperative intravenous iron injection. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    Brown, Hilary K; Hill, Jacquelyn; Natale, Renato

    2014-07-01

    To compare Caesarean section rates in a cohort of women in Southwestern Ontario over time, overall, and in patient subgroups defined by the Robson criteria, after adjusting for important medical and social characteristics. We obtained data from a perinatal database on deliveries at ≥ 22 weeks' gestation at a level II centre and a level III centre in London, Ontario between 1999 and 2010. Caesarean section rates were examined overall and in subgroups defined by parity, presentation, plurality, gestational age, and history of previous Caesarean section. Multivariable modified Poisson regression was used to compare Caesarean section rates in 2003-2006 and 2007-2010 versus 1999-2002. In the fully adjusted models, the overall Caesarean section rate was significantly higher in 2007-2010 than in 1999-2002 for the level II centre (adjusted relative risk [aRR] 1.12; 95% CI 1.05 to 1.21). An increase was also seen in the level III centre in both 2003 to 2006 (aRR 1.19; 95% CI 1.14 to 1.24) and 2007 to 2010 (aRR 1.17; 95% CI 1.12 to 1.22). Similar increases were seen over time among patient subgroups. Notably, repeat Caesarean sections without labour increased at the level II centre (2003 to 2006 aRR 1.21; 95% CI 1.01 to 1.45, and 2007 to 2010 aRR 1.44; 95% CI 1.21 to 1.71) and the level III centre (2003 to 2006 aRR 1.72; 95% CI 1.53 to 1.94, and 2007 to 2010 aRR 1.77; 95% CI 1.57 to 2.00). There has been a significant increase over time in the Caesarean section rate overall and in important subgroups. This increase remains even after controlling for other factors which may explain the trend.

    Full Text Available Background: Caesarean section is one of the most common interventions to overcome labor complications. However, pain cannot be avoided after the surgery. Lavender aromatherapy is considered as one of non-pharmacological therapy to reduce pain and increase beta-endorphin levels. Objective: To examine the effect of lavender aromatherapy on the intensity of pain and beta-endorphin levels in post-caesarean mothers. Methods: This was a quasy-experimental study with pretest and posttest with control group at Sembiring Delitua General Hospital on December 2016 to February 2017. There were 40 samples selected using purposive sampling, with 20 samples assigned in the experiment and control group. Numerical Rating Scale (NRS was used to measure pain and ELIZA methods to measure beta-endorphin levels. Independent t-test and paired t-test were used for data analysis Results: Results of this study showed that there was a significant difference in the mean value of pain intensity levels (p=0.000 and beta-endorphin levels (p=0.023 between experiment and control group. Conclusion: There was a significant effect of lavender aromatherapy on the decrease of pain intensity and the increase of beta-endorphin hormone in post-caesarean mothers. It is expected that lavender aromatherapy can be used as an alternative treatment to reduce pain and increase beta-endorphin levels in post-caesarean mothers.

    2010-02-01

    To describe the frequency of caesarean sections in a large sample of pedigree dogs in the UK. Data on the numbers of litters born in the previous 10 years were available from a cross-sectional study of dogs belonging to breed club members (2004 Kennel Club/BSAVA Scientific Committee Purebred Dog Health Survey). In this survey 151 breeds were represented with data for households that had reported on at least 10 litters (range 10-14,15): this represented 13,141 bitches which had whelped 22,005 litters. The frequency of caesarean sections was estimated as the percentage of litters that were reported to be born by caesarean section (caesarean rates) and are reported by breed. The dogs were categorised into brachycephalic, mesocephalic and dolicocephalic breeds. The 10 breeds with the highest caesarean rates were the Boston terrier, bulldog, French bulldog, mastiff, Scottish terrier, miniature bull terrier, German wirehaired pointer, Clumber spaniel, Pekingese and Dandie Dinmont terrier. In the Boston terrier, bulldog and French bulldog, the rate was > 80%. These data provide evidence for the need to monitor caesarean rates in certain breeds of dog.

    Full Text Available This study investigated efficacy and side effects of Morphine suppository for pain management after the first elective caesarean delivery in comparison to Diclofenac suppository. One hundred women aged 18-40 with term pregnancies undergoing elective caesarean section for the first time participated in this prospective project. Exclusion criteria included drug sensitivity, fetal malformations or defects, and complications during the cesarean operation. After same spinal anesthesia and same surgical techniques and in the recovery room patients consecutively received 100 mg diclofenac suppository or 10 mg morphine suppository. The pain severity was rated by “Numerical Rating Scale.” There was not the difference between two groups in terms of basal information. Pain score was significantly different between two groups in the first 12 hours (5.66 ±1.36 in morphine group and 3.63±0.96 in diclofenac group but not in the second 12 hour period. Considering pain scores every two hours in first 12 hours and every 4 hours in second 12 hours, morphine group had higher scores in comparison to diclofenac group. Also, the morphine group required pethidine injection sooner than the other group. The time giving first pethidine injection was 3.28±2.16 hours after operation in morphine group and 5.24±4.07 hours after operation (P<0.05. This study demonstrated that diclofenac suppository in comparison to morphine suppository decreased subjective pain scores in the first twenty-four hours after elective caesarean section which reached statistical significance in the first twelve hours. Although in diclofenac group, pethidine injection was prescribed significantly later.

    Full Text Available Background:: The effect of ilioinguinal and iliohypogastric (II-IH nerve block on postoperative pain is well documented when applied before Caesarean section but the efficacy remains unclear when applied after the surgical procedure. Therefore we investigated the effect of II-IH nerve block on postoperative pain and analgesic consumption in patients when applied after Caesarean Section. Methods: Sixty ASA I-II patients, scheduled for elective C/S were included in the study. After general anaesthesia was performed, the patients were allocated into 2 groups randomly. In Group I (n=30, bilateral II-IH block had been applied after the skin closure, with 10 ml of 0.5% ropivacaine on each side. In Group II (n=30 sham block had been applied. For postoperative analgesia all patients received tramadol via i.v patient controlled analgesia. VAS scores, tramadol consumption and side effects at 0th, 2nd, 4th, 6th, 8th, 12th, 16th, 20th, 24th hours were noted. Results: There was no difference between groups regarding demographical data. The mean VAS scores in Group I were significantly lower than in Group II at 6th (p=0.003, 8th (p=0.019, 12th (p=0.024, 24th hours (p=0.004 at rest and at 6th (p=0.022, 8th hours (p=0.047 with movement. Tramadol usage in Group I was significantly less than in Group II at all estimated time intervals (P=0.001. Total tramadol consumption was 331 ± 82 mg in Group I and 622±107 mg in group II (P=0.001. Conclusions: We observed that II-IH nerve block when applied after the surgery may reduce analgesic consumption after C/S.

    We present the case of a 31-year-old woman with Ehler-Danlos syndrome (EDS) type 2. She had a previous caesarean section and went on to have an uncomplicated vaginal birth in her last pregnancy. To our knowledge, this is the first case of a successful vaginal birth after caesarean section in a patient with EDS. EDS is a multisystem disorder involving a genetic defect in collagen and connective-tissue synthesis and structure. It is a heterogeneous group of 11 different inherited disorders. Obstetric complications in these patients include miscarriages, stillbirths, premature rupture of the membranes, preterm labour, uterine prolapse, uterine rupture and severe postpartum haemorrhage. There has been much controversy over the appropriate mode of delivery. Abdominal deliveries are complicated by delayed wound healing and increased perioperative blood loss. Vaginal deliveries may be complicated by tissue friability causing extensive perineal tears, pelvic floor and bladder lesions. Our case highlights that in specific, controlled situations it is possible to have a vaginal delivery even after previous caesarean section in patients with EDS.

    Full Text Available BACKGROUND Lower segment caesarean section is a common surgical procedure. Postpartum haemorrhage incidence after LSCS is 4%. Misoprostol is a prostaglandin E1 analogue with good uterotonic properties, easy availability, low cost, thermostability, long shelf life, easy administration and few adverse effects at therapeutic dose. It is readily absorbed by oral, sublingual, buccal, vaginal or rectal route. Sublingual route attains quickest concentration. Dose of 400 mcg was chosen in this study to minimise adverse effects with optimal therapeutic benefit. The aim of the study is to determine the efficacy of sublingual misoprostol in reducing caesarean blood loss. MATERIALS AND METHODS It is a prospective experimental study done in VSSIMSAR, Burla. Women undergoing LSCS were randomly assigned to study and control groups of equal strength of 100 each. In all cases, preoperative Hb%, haematocrit, pulse, BP was noted. Study group were given 400 mcg misoprostol at the time of cord clamping. In control group, nothing was given. In all patients, active management of third stage of labour was done by using oxytocin 10 IU (IV along with uterine massage. Blood loss soaked by tetra was calculated using formula, blood loss = wet weight-dry weight/1.05 (1.05 is constant. Amount of blood loss, postoperative Hb%, haematocrit, pulse rate, BP was noted in both groups and compared. BP and pulse were noted after 1 hour and Hb%, haematocrit were noted after 24 hours. RESULTS Study group showed significant decrease in total blood loss (around 117.9 mL as compared to control group. There was significant decrease in the postoperative fall in Hb in the study group as compared to control, the mean difference being 0.631 gm%. Study group also showed decrease in postoperative fall in haematocrit as compared to control, the mean difference being 0.055. CONCLUSION Misoprostol significantly reduced caesarean blood loss and doesn’t affect foetal outcome without significant

    The objective of our study was to determine, in accordance with WHO recommendations, the rates of Caesarean sections in a French perinatal network according to the Robson classification and determine the benefit of the medico-administrative data (PMSI) to collect this indicator. This study aimed to identify the main groups contributing to local variations in the rates of Caesarean sections. A descriptive multicentric study was conducted in 13 maternity units of a French perinatal network. The rates of Caesarean sections and the contribution of each group of the Robson classification were calculated for all Caesarean sections performed in 2014. The agreement of the classification of Caesarean sections according to Robson using medico-administrative data and data collected in the patient records was measured by the Kappa index. We also analysed a 6 groups simplified Robson classification only using data from PMSI, which do not inform about parity and onset of labour. The rate of Caesarean sections was 19% (14.5-33.2) in 2014 (2924 out of 15413 deliveries). The most important contributors to the total rates were groups 1, 2 and 5, representing respectively 14.3%, 16.7% and 32.1% of the Caesarean sections. The rates were significantly different in level 1, 2b and 3 maternity units in groups 1 to 4, level 2a maternity units in group 5, and level 3 maternity units in groups 6 and 7. The agreement between the simplified Robson classification produced using the medical records and the medico-administrative data was excellent, with a Kappa index of 0.985 (0.980-0.990). To reduce the rates of Caesarean sections, audits should be conducted on groups 1, 2 and 5 and local protocols developed. Simply by collecting the parity data, the excellent metrological quality of the medico-administrative data would allow systematisation of the Robson classification for each hospital.

  6. The role of caesarean section in modern Obstetrics

    Directory of Open Access Journals (Sweden)

    Alessandra Meloni

    2012-10-01

    Full Text Available Caesarean section (CS is a safe obstetric surgical procedure that contributes to reducing maternal and perinatal mortality and morbidity. Nevertheless, its advantages do not justify its continuous increase. During the last few years an average of 35% of deliveries have occurred by CS in Italy whereas an average of 20-25% is very common in other western countries. Although these percentages are very different, an important issue of modern obstetric Medicine is to ascertain whether the threshold of 15% proposed by the WHO in 1985 is actually adequate. Different medical, cultural, social, economic and medico-legal issues are of concern in the different countries and in contemporary society compared with the past. If we wish to discuss whether a new threshold should be proposed to reach the best balance between risks and benefits of CS in modern Obstetrics, it is mandatory to evaluate the reasons why these high percentages of CS occur in western countries and, in particular, in Italy. To reach this goal an optimal management of the delivery room should be pursued by implementing an organizational program, considering the objective delivery trend (Robson’s ten group classification and organizing continuous audit processes. The potential concern for the medico-legal issue, women’s choice and the use of analgesia in childbirth must be taken into account.

  7. Revisiting "The evolution of reciprocity in sizable groups": continuous reciprocity in the repeated n-person prisoner's dilemma.

    Science.gov (United States)

    Takezawa, Masanori; Price, Michael E

    2010-05-21

    For many years in evolutionary science, the consensus view has been that while reciprocal altruism can evolve in dyadic interactions, it is unlikely to evolve in sizable groups. This view had been based on studies which have assumed cooperation to be discrete rather than continuous (i.e., individuals can either fully cooperate or else fully defect, but they cannot continuously vary their level of cooperation). In real world cooperation, however, cooperation is often continuous. In this paper, we re-examine the evolution of reciprocity in sizable groups by presenting a model of the n-person prisoner's dilemma that assumes continuous rather than discrete cooperation. This model shows that continuous reciprocity has a dramatically wider basin of attraction than discrete reciprocity, and that this basin's size increases with efficiency of cooperation (marginal per capita return). Further, we find that assortative interaction interacts synergistically with continuous reciprocity to a much greater extent than it does with discrete reciprocity. These results suggest that previous models may have underestimated reciprocity's adaptiveness in groups. However, we also find that the invasion of continuous reciprocators into a population of unconditional defectors becomes realistic only within a narrow parameter space in which the efficiency of cooperation is close to its maximum bound. Therefore our model suggests that continuous reciprocity can evolve in large groups more easily than discrete reciprocity only under unusual circumstances. Copyright (c) 2010 Elsevier Ltd.

    This paper portrays the genetic variation observed at three tetrameric short tandem repeat (STR) loci HumTHO1, TPOX, and CSF1PO in five ethnic population groups from northeastern India. The study also specifies the suitability of use of these markers for forensic testing. The populations studied included three tribal groups (Kuki, Naga and Hmar), one Mongoloid caste group (Meitei), and a religious caste group (Manipuri Muslims). The loci were highly polymorphic in the populations, and all loci met Hardy-Weinberg expectations. No evidence for association of alleles among the loci was detected. The probability of match for the three loci of the most frequent genotype in the five population groups ranged between 2.6 x 10(-4) and 6.6 x 10(-5). The average heterozygosity among the population groups was approximately 70% with the overall extent of gene differentiation among the five groups being high (Gst = 0.046). Genetic affinity among the populations reveal very close association between the Kuki, Hmar, Naga, and Meitei. The Manipuri Muslims, despite being found in the same region, have had no admixture with these populations and maintain a substantial distance with the other groups. The genetic polymorphism data suggest that the studied systems can be used for human identity testing to estimate the frequency of a multiple locus STR DNA profile in population groups of northeastern India.

  9. Refusal of emergency caesarean section in Ireland: a relational approach.

    Science.gov (United States)

    Wade, Katherine

    2014-01-01

    This article examines the issue of emergency caesarean section refusal. This raises complex legal and ethical issues surrounding autonomy, capacity, and the right to refuse treatment. In Ireland, the situation is complicated further by the constitutional right to life of the unborn. While cases involving caesarean section refusal have occurred in other jurisdictions, a case of this nature has yet to be reported in Ireland. This article examines possible ways in which the interaction of a woman's right to refuse treatment and the right to life of the unborn could be approached in Ireland in the context of caesarean section refusal. The central argument of the article is that the liberal individualistic approach to autonomy evident in the caesarean section cases in England and Wales is difficult to apply in the Irish context, due to the conflicting constitutional rights of the woman and foetus. Thus, alternative visions of autonomy which take the interests and rights of others into account in medical decision-making are examined. In particular, this article focuses on the concept of relational consent, as developed by Alasdair Maclean and examines how such an approach could be applied in the context of caesarean section refusal in Ireland. The article explains why this approach is particularly appropriate and identifies mechanisms through which such a theory of consent could be applied. It is argued that this approach enhances a woman's right to autonomy, while at the same time allows the right to life of the unborn to be defended.

    Full Text Available Background and Objective: We conducted this study to evaluate and compare postpartum sexual functioning after vaginal and caesarean births. Materials and Methods: This was a cross-sectional study that was carried out in postnatal health care in a hospital. A total of 50 primiprous women who had given birth 6-12 months ago and came to the hospital for postnatal care were asked to join the study. Forty of the women completed the entire questionnaire. Among these women, 20 delivered spontaneously with mediolateral episiotomy and 20 had elective caesarean section. Sexual function was evaluated by a validated, self-created questionnaire. A statistical evaluation was carried out by SPSS v.11. A two-part self-created validated questionnaire for data collection was administered regarding sexual function prior to pregnancy and 6-12 months postpartum. Results: The median time to restart intercourse in the normal vaginal delivery with episiotomy (NVD/epi group was 40 days and in the caesarean section (C/S group was 10 days postpartum. The most common problems in the NVD/epi group was decreased libido (80%, sexual dissatisfaction (65%, and vaginal looseness (55%. In the C/S group, the most common problems were vaginal dryness (85%, sexual dissatisfaction (60%, and decreased libido (35%. There were clinically significant differences between the two groups regarding sexual outcomes, but these differences were not statically significant. Conclusion: Postnatal sexual problems were very common after both NVD/epi and C/S. Because sexual problems are so prevalent during the postpartum period, clinicians should draw more attention to the women′s sexual life and try to improve their quality of life after delivery.

    Dystocia is the leading indication for primary caesarean sections. Our aim is to compare two approaches in the management of dystocia in labor in nulliparous women with a singleton fetus in cephalic presentation at term in spontaneous or induced labor. Prospective cohort study. Four hundred and nineteen consecutive patients were divided into two groups: the standard management group (SM), in acceleration of labor was commenced at the "action line" in the case of arrested or protracted labor, and the comprehensive management group (CM) in which arrested or protracted labor was considered as a warning sign promoting further diagnostic assessment prior to considering intervention. Caesarean sections rate was 22.2 % in the SM group (216 patients) and 10.3 % in the CM group (203 patients) (p = 0.001). The rate of oxytocin use decreased from 33.3 % in SM group to 13.8 % in the CM group (p dystocia enabled us to achieve a reduction in iatrogenic interventions in labor while maintaining good neonatal outcomes.

    Full Text Available BACKGROUND Caesarean section (Sectio Caesarea is a surgical method for the completion of delivery. After various historical modifications of operative techniques, modern approach consists in the transverse dissection of the anterior wall of the uterus. The rate of vaginal birth after caesarean section was significantly reduced from year to year and the rate of repeated caesarean section is increased during the past 10 years. Evaluation of scar thickness is done by ultrasound, but it is still debatable size of thick scar that would be guiding “cut-off value” for the completion of the delivery method. To better assess the risk of uterine rupture, some authors have proposed sonographic measurement of lower uterine segment thickness near term assuming that there is an inverse correlation between LUS thickness and the risk of uterine scar defect. Therefore, this assessment for the management of women with prior CS may increase safety during labour by selecting women with the lowest risk of uterine rupture. The aim of the study is to study the diagnostic accuracy of sonographic measurements of the Lower Uterine Segment (LUS thickness near term in predicting uterine scar defects in women with prior Caesarean Section (CS. We aim to ascertain the best cut-off values for predicting uterine rupture. MATERIALS AND METHODS 100 antenatal women with history of previous one LSCS who come to attend antenatal clinic will be assessed for scar thickness by transabdominal ultrasonography and its correlation with intraoperative findings. This prospective longitudinal study was conducted for 1 year after IEC approval with inclusion criteria previous one LSCS. Exclusion criteria- 1 Previous myomectomy scar; 2 Previous 2 LSCS; 3 Previous hysterotomy scar. RESULTS Our findings indicate that there is a strong association between degree of LUS thinning measured near term and the risk of uterine scar defect at birth. In our study, optimal cut-off value for predicting

    While opioids are the mainstay for post-operative analgesia after lower segment caesarean section, they are associated with various untoward effects. Ultrasound guided transversus abdominis plane (TAP) block has been postulated to provide effective analgesia for caesarean section. We evaluated the analgesic efficacy of this block for post caesarean analgesia in a randomised controlled trial. One hundred thirty-nine mothers undergoing caesarean delivery were randomised to receive TAP block with either 20 ml 0.375% ropivacaine or 20 ml saline after obtaining informed consent. All the subjects received a standard spinal anaesthetic and diclofenac was administered for post-operative pain. Breakthrough pain was treated with tramadol. Post-operatively, all the subjects were assessed at 0, 2, 4, 6, 8, 10, 12, 18 & 24 h. The primary outcome was the time to first analgesic request. The secondary measures of outcome were pain, nausea, sedation, number of doses of tramadol administered and satisfaction with the pain management. The median (interquartile range) time to first analgesic request was prolonged in the TAP group compared to the control group (p consumption when used for multimodal analgesia for pain relief after caesarean section. However, the risk of local anaesthetic systemic toxicity remains unknown with this block. Hence larger safety trials and measures to limit this complication need to be ascertained. The trial was registered with the Clinical Trial Registry of India ( CTRI/2017/03/008194 ) on 23/03/2017 (trial registered retrospectively).

    PurposeTo explore the efficacy and safety of prophylactic temporary balloon occlusion of the infrarenal abdominal aorta during caesarean for the management of patients with placenta praevia accreta.MethodsTwo hundred and sixty-eight cases of placenta praevia accreta from January 2012 to June 2015 were retrospectively reviewed. Group A included two hundred and thirty patients who underwent prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section. Group B included thirty-eight patients who underwent caesarean without endovascular intervention. The parameters including operating room time, estimated blood loss, blood transfusion volume, PT (prothrombin time) during operation, days in the intensive care unit, and total hospital days were compared between the two groups.ResultsThe operating room time, estimated blood loss, PT, the incidence of hysterectomy, blood transfusion volume, postpartum haemorrhage, and days in intensive care unit were lower in group A than in group B, with statistical significance (P < 0.05). There was no significant difference in the Apgar scores of the neonates and the incidences of thrombosis in lower limbs between the two groups (P > 0.05). No patient in the group with prophylactic temporary balloon occlusion of the infrarenal abdominal aorta was performed hysterectomy, while three patients in group B were performed hysterectomy because of uncontrollable haemorrhage.ConclusionsThe results indicate that prophylactic temporary balloon occlusion of infrarenal abdominal aorta followed by caesarean section is safe and effective to control intraoperative blood loss and greatly decreases the risk of hysterectomy in patients with placenta praevia accreta.

    Full Text Available In obstetrics postoperative cognitive dysfunctions may take place after caesarean section and vaginal delivery with poor results both for mother and child. The goal was to study influence of anesthesia techniques following caesarian section on memory, perception and speech. Having agreed with local ethics committee and obtained informed consent depending on anesthesia method, pregnant women were divided into 2 groups: 1st group (n=31 had spinal anesthesia, 2nd group (n=34 – total intravenous anesthesia. Spinal anesthesia: 1.8-2.2 mLs of hyperbaric 0.5% bupivacaine. ТIVА: Thiopental sodium (4 mgs kg-1, succinylcholine (1-1.5 mgs kg-1. Phentanyl (10-5-3 µgs kg-1 hour and Diazepam (10 mgs were used after newborn extraction. We used Luria’s test for memory assessment, perception was studied by test “recognition of time”. Speech was studied by test "name of fingers". Control points: 1 - before the surgery, 2 - in 24h after the caesarian section, 3 - on day 3 after surgery, 4 - at discharge from hospital (5-7th day. The study showed that initially decreased memory level in expectant mothers regressed along with the time after caesarean section. Memory is restored in 3 days after surgery regardless of anesthesia techniques. In spinal anesthesia on 5-7th postoperative day memory level exceeds that of used in total intravenous anesthesia. The perception and speech do not depend on the term of postoperative period. Anesthesia technique does not influence perception and speech restoration after caesarean sections.

    To evaluate the safety of electrocautery for coagulation during Caesarean sections. A randomized, controlled, clinical pilot study was performed at a university maternity hospital. After admission for delivery and decision to perform a C-section, volunteers were randomized to either the intervention group (use of electrocautery for coagulation) or nonintervention group. The women were examined at the time of postpartum discharge (day 3), at days 7 to 10, and again at days 30 to 40 for signs of infection, hematoma, seroma, or dehiscence. Data were analyzed using an intention-to-treat analysis, and risk ratios were calculated. No significant differences were found between the two groups. Only 2.8% of patients in the intervention group developed surgical wound complications during hospitalization. However, 7 to 10 days following discharge, these rates reached 23.0% and 15.4% in the intervention and nonintervention groups, respectively (RR = 1.50, 95% CI = 0.84-2.60). Further studies should confirm whether the use of electrocautery for coagulation does not increase the risk of surgical wound complications in patients undergoing Caesarean sections.

    Aim: To evaluate the feasibility and efficacy of routine uterine artery embolization (UAE) immediately after planned caesareans performed in the cath lab for conservative treatment of placenta accreta. Materials and methods: A retrospective study included all patients who had a planned caesarean in the cath lab for conservative treatment of placenta accreta at Angers University Hospital, which is a tertiary care centre, from April 2001 to September 2010. Twelve patients underwent UAE immediately after caesarean with the placenta left partially or totally in situ. The success rate of embolization, blood loss, and complications were reported. Results: Diagnosis of abnormal placentation was confirmed by caesarean findings in 14 cases. Four patients had a percreta form with bladder invasion. In seven cases blood loss was insignificant and UAE was prophylactic; no secondary haemorrhage was observed in this group. Postpartum haemorrhage occurred in five cases: control of immediate postpartum bleeding by embolization was successful in three and failed in two leading to hysterectomy. In one case uterine necrosis occurred 6 weeks after embolization, requiring a hysterectomy. Delayed complications resulted in hysterectomy and partial bladder resection 3 months after delivery for one of the patients with placenta percreta. Conclusion: UAE immediately after a caesarean performed in the cath lab is a feasible therapeutic option for conservative treatment of placenta accreta. Advantages include reducing stress and risks associated with transferring women with potentially unstable haemodynamics.

    1999-04-01

    In a prospective, randomized, double-blind study in 55 women undergoing elective caesarean section under spinal anaesthesia, we compared epidural diamorphine 3 mg (2 distinct boluses, group ED) with single-dose intrathecal morphine 0.2 mg (group SM), in terms of analgesic efficacy, patient satisfaction and side-effects at 2, 3, 4, 8, 12, 16, 24 and 28 h postoperatively. There were no significant differences between groups in pain (assessed by 100 mm visual analogue scale), incidence of pruritus, sedation or respiratory depression measured by continuous pulse oximetry. However, time to first request for supplementary oral analgesia was longer in SM than in ED (mean +/- SD: 22.3+/-12.0 h vs. 13.8+/-6.5 h, P=0.04). The incidence of nausea or vomiting was significantly higher in SM than ED (73% vs. 41%, P=0.01). In ED, the mean +/- SD time to requirement of the second bolus was 6.7+/-3.2 h. There was a high level of satisfaction in both groups. We conclude that two boluses of epidural diamorphine 3 mg and single-dose intrathecal morphine 0.2 mg provide satisfactory analgesia after caesarean section, but spinal morphine was associated with both delayed requirement for supplementary analgesia and a higher incidence of nausea and vomiting.

    2009-03-01

    Full Text Available INTRODUCTION: Uterine arteriovenous malformations are classified as acquired or congenital. Caesarean section which is performed more frequently on nowadays, uterine curettage and other uterine surgeries are the most common causes of the acquired arteriovenous malformations. CASE: Twenty-two years old woman delivered her second child by caesarean section, due to history of caesarean section, was admitted with complaint of profuse vaginal bleeding 15 days after the surgery. She demonstrated the clinical features of the hypovolemic shock. At first she treated with four units of red blood suspension, two units of fresh frozen plasma and rapid infusion of the fluids. On endometrial curettage only blood and coagulum were obtained. The bleeding could only be controlled by the internal pressure of the 18 F Foley catheter. Doppler analyze of the uterus revealed a vascular malformation signifying a turbulent flow pattern with low pressure and high flow rate. A unilateral uterine artery embolization was performed her and her menstruel cycles are resumed at the fifth month of the puerperium. DISCUSSION: The clinical presentation of the uterine arteriovenous malformations depends on the localization and the dimensions of the malformation. The uterine arteriovenous malformation should be kept in mind in cases of late occurrence vaginal bleeding unresponsive to the uterotonic medications, especially in a woman with previous history of uterine damage, such as curettage or caesarean section.

    2016-07-01

    To quantify maternal obesity as a risk factor for Caesarean delivery in sub-Saharan Africa. Multivariable logistic regression analysis using 31 nationally representative cross-sectional data sets from the Demographic and Health Surveys (DHS). Maternal obesity was a risk factor for Caesarean delivery in sub-Saharan Africa; a clear dose-response relationship (where the magnitude of the association increased with increasing BMI) was observable. Compared to women of optimal weight, overweight women (BMI 25-29 kg/m(2) ) were significantly more likely to deliver by Caesarean (OR: 1.54; 95% CI: 1.33, 1.78), as were obese women (30-34.9 kg/m(2) (OR: 2.39; 95%CI: 1.96-2.90); 35-39.9 kg/m(2) (OR: 2.47 95%CI: 1.78-3.43)) and morbidly obese women (BMI ≥40 kg/m(2) OR: 3.85; 95% CI: 2.46-6.00). BMI is projected to rise substantially in sub-Saharan Africa over the next few decades and demand for Caesarean sections already exceeds available capacity. Overweight women should be advised to lose weight prior to pregnancy. Furthermore, culturally appropriate prevention strategies to discourage further population-level rises in BMI need to be designed and implemented. © 2016 The Authors.

    Full Text Available To assess the cognition of patients with multiple sclerosis (MS using the Rao's Brief Repeatable Battery of Neuropsychological Tests (BRB-N. METHOD: BRB-N was translated and adapted for control subjects. Subsequently, it was applied to a group of patients with relapsing-remitting (RR MS. RESULTS: The assessment on the healthy controls (n=47 showed that the correlation between tests on the same cognitive domain was high and that there was a five-factor solution that explained 90% of the total variance. Except for the Word List Generation subset of tests, the performance of patients with RRMS (n=39 was worse than that of the healthy controls. CONCLUSION: BRB-N is a relatively simple method to assess cognition of patients with MS in the daily clinic. It does not take long to apply and does not require special skills or equipment.

    To compare the morbidity associated with placenta previa with and without previous caesarean sections. Study Design: Retrospective comparative study. Place and Duration of Study: From March 2014 till March 2016 in the department of Obstetrics and Gynaecology at PNS Shifa hospital Karachi. Material and Methods: After the approval from hospital ethical committee, antenatal patients with singleton pregnancy of gestational age >32 weeks, in the age group of 20-40 years diagnosed to have placenta previa included in the study. All patients with twin pregnancy less than 20 years and more than 40 years of age were excluded. The records of all patients fulfilling the inclusion criteria were reviewed. Data had been collected for demographic and maternal variables, placenta previa, history of previous lower segment caesarean section (LSCS), complications associated with placenta previa and techniques used to control blood loss were recorded. Results: During the study period, 6879 patients were delivered in PNS Shifa, out of these, 2060 (29.9%) had caesarean section out of these, 47.3% patients had previous history of LSCS. Thirty three (1.6%) patients were diagnosed to have placenta previa and frequency of placenta previa was significantly higher in patients with previous history of LSCS than previous normal delivery of LSCS i.e. 22 vs. 11 (p=0.023). It was observed that the frequency of morbidly adherent placenta (MAP) and Intensive care unit (ICU) stay were significantly higher in patients with previous history of LSCS than previous history of normal delivery. Conclusion: Frequency of placenta previa was significantly higher in patients with history of LSCS. Also placenta previa remains a major risk factor for various maternal complications. (author)

    Cow milk allergy (CMA) is the most common food allergy in breastfed infants. The aim of this study is to verify whether certain perinatal factors may influence the development of CMA immunoglobulin E (IgE)+. A retrospective, observational study of case and control groups was carried out. Information was collected of patients with CMA IgE+ from our department during the years 1990-2013. Patients of the same age and sex were recruited for the control group. Information on the following variables was collected: sex, age, pregnancy tolerance, duration of pregnancy, type of delivery, isolated doses of formula feeding in hospital (FFH), duration of breastfeeding, and family history of allergy (defined as ≥1 first-degree family member with allergic disease). Statistical analysis was performed using multivariate logistic regression techniques. A total of 211 cases were included in this study. Multivariate analysis showed an influence of duration of breastfeeding, FFH to be a risk factor (OR 4.94; 95% CI 2.68-9.08), especially in caesarean delivery (OR 11.82; 95% CI 2.64-47.50), and prematurity (OR 0.29; 95% CI 0.09-0.92) to be a protective factor. Perinatal factors play a key role in the development of CMA IgE+, with an influence of breastfeeding duration, FFH and caesarean delivery as risk factors and prematurity as a protective factor. While family history had no important role, environmental factors were more decisive. © 2017 S. Karger AG, Basel.

    The Royal College of Obstetrics and Gynaecology guidelines state that all uncomplicated breech Presentation should be offered external cephalic version and all such women should be briefed about the risks and benefits of external cephalic version and all such women should be briefed about the risks and benefits of external cephalic version before undertaking the procedure. To ascertain the acceptability of external cephalic version before elective caesarean section for breech Presentation by pregnant ladies and see whether they were adequately informed about the risks and benefits. The clinical audit was registered with the audit department at Watford general hospital and written Consent for the access of medical records was obtained. A retrospective view of 86 accessible medical records out of Total 110 elective breech caesarean sections was done over a period of one year. This retrospective study was conducted at the gynaecology and obstetrics department at Watford general hospital, Watford United Kingdom. Written consent for the access of medical records was obtained. All women who under went elective caesarean section due to breech presentation were included in the study. Out of a total of 110 elective breech caesarean sections performed, the data on 86 cases was selected for the final analysis. The information gathered included patient's profile, whether patient was informed of risks and benefits of external cephalic version, recognition of obstetric risk factors, external cephalic version performed and its success. Out of total 86 caesarean sections 46 were suitable for external cephalic version of whom 37 cases were offered external cephalic version. Among 37 patients who were offered external cephalic version only 15 patients accepted (22 declined) the procedure. Moreover, it was found that the documentation of risk/benefit explanation of the procedure was inadequate. External cephalic version was not successful in any of the patient. Causes for

    Full Text Available Implantation of a pregnancy in a scar after Caesarean section is one of the rarest locations of ectopic pregnancies. A diagnosis and/or treatment which is too late may lead to a uterine rupture, the necessity to remove the uterus and a significant increase in morbidity among mothers. The study presents a diagnostically difficult case of a 29-year-old woman, who was diagnosed with pregnancy in its seventh week, located in a scar after a Caesarean section, with highly increased values of human chorionic gonadotropin (β-HCG concentration in blood serum. The pregnancy was removed and the wound was stitched during laparotomy, without a need to remove the uterus.

    Classic metaphyseal lesion (CML) is the term given to a fracture that most often occurs in the posteromedial aspect of the distal femur, proximal tibia, distal tibia, and proximal humerus in infants; this finding is strongly associated with non-accidental injury. To demonstrate that the CML may occur following simple lower segment caesarean section (LSCS). A review of 22 years of an obstetric practice that delivers 8,500 babies per year. We identified three neonates born by elective LSCS, each with distal femoral metaphyseal fractures on postpartum radiographs. All caesarean sections were elective and uncomplicated. External cephalic version was not employed preoperatively. Postpartum radiographs demonstrated a fracture of the distal femoral metaphysis in each neonate, typical of a CML. We propose that a CML can occur in the setting of a simple, elective and uncomplicated LSCS where no external cephalic version is employed. (orig.)

    Our aim was to determine the service quality of delivered care for people with Caesarean Section and Normal Delivery. A cross-sectional study was conducted among 200 people who had caesarean section and normal delivery in Al-Zahra Teaching Hospital in Tabriz, north western Iran. Service quality was calculated using: Service Quality = 10 - (Importance × Performance) based on importance and performance of service quality aspects from the postpartum women's perspective.A hierarchical regression analysis was applied in two steps using the enter method to examine the associations between demographics and SQ scores. Data were analysed using the SPSS-17 software. "Confidentiality", "autonomy", "choice of care provider" and "communication" achieved scores at the highest level of quality; and "support group", "prompt attention", "prevention and early detection", "continuity of care", "dignity", "safety", "accessibility and "basic amenities" got service quality score less than eight. Statistically significant relationship was found between service quality score and continuity of care (P=0.008). A notable gap between the participants‟ expectations and what they have actually received in most aspects of provided care. So, there is an opportunityto improve the quality of delivered care.

    2009-07-01

    Full Text Available Background. The incidence of obesity has undergone a dramatic increase around the world during the last few years. Such epidemic behavior has been associated with obstetric patient’s frequent presentation of different stages of obesity when undergoing anesthetic procedure. Obesity in pregnant women involves the risk of adverse maternal and fetal outcomes. Hypertension and preeclampsia, diabetes, fetal macrosomia, caesarean delivery, difficult airway management and neuroaxial techniques are more likely to be performed in this group of patients. Materials and methods. This is a case report of a morbid obese patient scheduled for caesarean delivery and tubal ligation. Regional, spinal and epidural techniques were attempted for surgery with unsuccessful results; this entails general anesthesia for surgery. The literature on complications due to obesity during pregnancy was reviewed, emphasising relevance for the anesthesiologist. Conclusion. Obesity, especially morbid obesity in pregnant women, represents a challenge for anesthesia management. Updated knowledge of physiology and the conditions related to obesity in pregnancy is necessary; medical services must be prepared to provide optimum and safe obstetric anesthesia, analgesia and post-operation care.

    Objective: To compare the safety and efficacy of 10 units of intravenous syntocinon alone with 10 units intravenous syntocinon and 0.25 mg intramuscular ergometrine in the prevention of atonic uterine haemorrhage during caesarean section. Method: The quasi-experimental study was conducted at the Maternal and Child Health Centre, Unit I, Pakistan Institute of Medical Sciences, Islamabad, from November 1, 2010 to February 28, 2011. All women undergoing caesarean section were included in the study. Patients were given intravenous 10 units syntocinon alone intra-operatively from November 1 to December 31, 2010, while 0.25 mg ergometrine intramuscular was added to 10 units intravenous syntocinon from January 1 to February 28, 2011. Frequency of postpartum haemorrhage, adverse effects of drugs and maternal morbidity and mortality were assessed by using chi square test. P <0.05 was taken as statistically significant. Results: Of the total number of 701 subjects, 378 (54%) women were given 10 units syntocinon and 323 (46%) were given 0.25 mg ergometrine in addition to 10 units syntocinon. The mean age in the syntocinon group was 28+-3.5 yrs with gestational age of 37.5+-2 weeks, while that in syntocinon-ergometrine group was 29+-3.4 years and 38+-2 weeks respectively. Postpartum haemorrhage in the syntocinon group was found in 38 (10%) women versus 05 (1.5%) women) in the other group (p<0.001). Adverse effects like nausea, vomiting and raised blood pressure were slightly more with syntocinon-ergometrine than syntocinon alone (n=56; 15.3% vs n=35; 9.2%), but it was not statistically significant. Post partum haemorrhage was responsible for 40% of maternal mortality during the study period and that was in the syntocinon group. Conclusion: Prophylactic ergometrine in addition to syntocinon is superior to syntocinon alone in decreasing frequency of postpartum haemorrhage in caesarean section and associated maternal morbidity and mortality. Regarding safety profile, the two

    This study, based on the Lebanese National Perinatal Survey which included 5231 women, examined the relations between the caesarean section (CS) rate and the characteristics of mothers, children, antenatal care and maternity units in two geographical zones of Lebanon (Beirut-Mount Lebanon and the rest of the country) and then looked at geographical variations. This analysis concerned 3846 women with singleton pregnancies and livebirths at low risk of CS, after exclusion of women with a previous CS, non-cephalic fetal presentations, or delivery before 37 weeks' gestation. The principal end point was caesarean delivery. The relations between the factors studied and CS were estimated by odds ratios (OR), both crude and adjusted, using logistic regression. The rate of CS was higher in the Beirut-Mount Lebanon zone than elsewhere (13.4% vs. 7.6%). After adjustment, several factors remained associated with caesarean delivery in each zone. Common factors were primiparity, gestational age > or = 41 weeks and antenatal hospitalisation. Factors identified only in the Beirut-Mount Lebanon zone were obstetric history and insurance coverage, whereas for the other zones we only found major risk factors for obstetric disease: maternal age > or = 35 years, number of antenatal consultations > or = 4 and birthweight Lebanon (OR = 1.80 [95% CI 1.09, 2.95]). In conclusion, the CS rates in Lebanon were high, with geographical differences that were associated with access to care and with obstetric practices.

    To estimate the incidence of scar endometriosis after different surgical procedures. A retrospective study of 72 patients diagnosed with scar endometriosis between 1978 and 2003 was performed. Patient age, site of endometriosis, previous operations, time-gap between last surgery and onset of symptoms, nodule characteristics, and recurrence were evaluated. Age ranged from 16 to 48 years. Location varied according to the previous surgery: 46 caesarean section, one hysterectomy, one in abdominal surgery, 19 episiotomy, one was a relapse and two pelvic floor procedures, two women with no previous surgery. The incidence of scar endometriosis after caesarean section was significantly higher than after episiotomy (0.2 and 0.06%, respectively: p<0.00001) with a relative risk of 3.3. Pain was the most frequent symptom. The mean time between surgery and onset of symptoms was 3.7 years. Our findings confirm that scar endometriosis is a rare condition and indicate, probably for the first time, that caesarean section greatly increases the risk of developing scar endometriosis.

    Objective: To establish as reliable and valid the nine-point global rating scale for assessing residents' independent performance of Caesarean Section. Methods: The validation study was conducted at the Department of Obstetrics and Gynaecology, Aga Khan University Hospital, from April to December 2008, and comprised 15 residents during 40 Caesarean Sections over 9 months. Independently two evaluators rated each procedure and the difficulty of each case. Results: The observations per faculty ranged from 1-8 (mean 4.07+- 2.56). The Year 4 residents were observed the most i.e. 32 (40%), followed by Year 3, 30 (37.5%); Year 2; 14 (17.5%); and Year 1, 4 (5%). Mean time required for observation of the surgery was 43.81+-14.28 (range: 20-90) with a mode of 45 min. Mean aggregate rating on all items showed gradual progression with the year of residency. The assessment tool had an internal consistency reliability (Cronbach's alpha) of 0.9097 with low inter-rater reliability. Conclusion: The evaluation tool was found to be reliable and valid for evaluating a resident's competence for performing Caesarean Section. Training of the assessors is required for a better inter-rater agreement. (author)

    We retrospectively documented indications for Caesarean sections in a rural district level hospital in the highlands of Papua New Guinea. Over a 53-month study period, 745 Caesarean sections were performed. Prolonged labour, previous history of Caesarean section, cephalopelvic disproportion, malpresentation and fetal distress accounted for over 88% of Caesarean sections performed. In older mothers (aged >30 years), antepartum haemorrhage (Fisher exact test, P = 0.05) and multiple indications (P = 0.001) were leading reasons for Caesarean sections while cephalopelvic disproportion (P = 0.005) was the leading indication in younger mothers. Further prospective studies incorporating perinatal and maternal mortality rates are required to optimise the value of Caesarean sections at district level hospitals in Papua New Guinea. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    INTRODUCTION: Caesarean section is thought to be a risk factor for childhood asthma, but this association may be caused by confounding from, for instance, familial factors. To address this problem, we used twin pairs to assess the risk of childhood asthma after emergency caesarean section. METHODS...... respiratory morbidity, the risk of childhood asthma following emergency caesarean section remained unchanged. CONCLUSION: Emergency caesarean section was not associated with childhood asthma. FUNDING: none. TRIAL REGISTRATION: not relevant.......: In total, 464 twin pairs (928 twins) were included. In 30 pairs, the first twin (vaginal delivery) was diagnosed with asthma, but the second twin (emergency caesarean section) was not. In 20 pairs, the second twin (emergency caesarean section) was diagnosed with asthma, but the first twin (vaginal delivery...

    Because of their sensitivity and high level of discrimination, short tandem repeat (STR) maker systems are currently the method of choice in routine forensic casework and data banking, usually in multiplexes up to 15-17 loci. Constraints related to sample amount and quality, frequently encountered in forensic casework, will not allow to change this picture in the near future, notwithstanding the technological developments. In this study, we present a free online calculator named PopAffiliator ( http://cracs.fc.up.pt/popaffiliator ) for individual population affiliation in the three main population groups, Eurasian, East Asian and sub-Saharan African, based on genotype profiles for the common set of STRs used in forensics. This calculator performs affiliation based on a model constructed using machine learning techniques. The model was constructed using a data set of approximately fifteen thousand individuals collected for this work. The accuracy of individual population affiliation is approximately 86%, showing that the common set of STRs routinely used in forensics provide a considerable amount of information for population assignment, in addition to being excellent for individual identification.

    Full Text Available BACKGROUND There are few issues in modern obstetrics that have been as controversial as management of a woman with a prior caesarean delivery. Hence, it is required to have evidence based correct practice of this surgical procedure. Healing of the uterine incision and the strength of the scar should be the most important consideration. The aim of the study is to compare the effect of technique of uterine closure (Single Layer vs. Double Layer on subsequent pregnancies and to find out, which technique has a better maternal and neonatal outcome by strengthening the scar. MATERIALS AND METHODS 500 cases of previous caesarean section pregnancies were taken, 250 from single layer closure group and 250 from double layer closure group. The mode of delivery during present pregnancy was noted. Integrity of scar, thickness of scar, presence of adhesion were documented. The neonates were observed. Results were compared so as to draw an inference about the better method. RESULTS Mean age between the two groups were similar. Majority did not have history of premature rupture of membrane during previous pregnancy. Postoperative complications were more when double layer closure of uterine scar was done in index surgery. Interpregnancy gap of <3 years was more commonly present in double layer closure group (52.8% in double layer versus 34.8% in single layer. Single layer had more scar tenderness (21.2%, thinned out scars (34.6%, incomplete ruptures (7.1% and complete ruptures (2.8% than double layer closure group. Neonatal outcomes were not statistically different in both the groups. CONCLUSION Double layer uterine closure seems to have better impact on scar integrity as compared to single layer uterine closure.

    2012-01-01

    Background: In the past 30 years the rate of caesarean section (C/S) has steadily increased from 5% to more than 20% for many avoidable and unavoidable indications. The objective of this study was to compare maternal morbidity and determine its cause in elective and emergency caesarean section. Method: It was a cross-sectional comparative study conducted in Civil Hospital Karachi at Obs/Gyn Unit III. All mothers admitted through OPD or emergency during the study period, of any age or parity undergoing C/S were recruited in the study. Patients having previous myomectomy, hysterotomy or classical C/S were excluded from the study. Patients undergoing emergency C/S were placed in group A, and those delivered by elective C/S were included in group B. Study variables were general and obstetric parameters and complications observed intra-operatively. Any postoperative complications were recorded from recovery room till patient was discharged from the ward. Results: There were 50 patients in each group. In group A, 11 (22%) were booked and 33 (66%) were referred cases. In group B, 48 (96%) were booked. The mean age in both groups was 28 years. In both groups, multigravida compared to primigravida were 78% vs 22% in group A, and 92% vs 8% in group B. Indication for C/S was previous C/S in 10 (20%) patients in group A, and 39 (78%) patients in group B, placenta previa, chorioamionitis, obstructed labour (6, 12% each); pregnancy induced hypertension and eclampsia in 5 (10%) cases in group A only. Intra-operative complications in group A were 48 (96%) vs 15 (30%) in group B (p=0.000). Postoperative morbidity in group A was 50 (100%) and 26 (52%) in group B (p=0.000). Intra-operative complication was haemorrhage in 46 (92%) cases in group A and 11 (22%) in group B. Anaesthetic complications were 40 (80%); prolonged intubation 25 (50%), aspiration of gastric contents 8 (16%), and difficult intubation 7 (14%) in group A. Ten (20%) cases had anaesthetic complications in group B

Selection criteria Articles with objective scientific information or advice, comments, opinions, or the experience of ordinary women or celebrities on delivery by caesarean section. Main outcome measures Sources of information mentioned by the author of the article, the accuracy and completeness of data presented on caesarean section, and alleged reasons why women would prefer to deliver though caesarean section. Results 118 articles were included. The main cited sources of information were health professionals (78% (n=92) of the articles). 71% (n=84) of the articles reported at least one benefit of caesarean section, and 82% (n=97) reported at least one short term maternal risk of caesarean section. The benefits most often attributed to delivery by caesarean section were reduction of pain and convenience for family or health professionals. The most frequently reported short term maternal risks of caesarean section were increased time to recover and that it is a less natural way of giving birth. Only one third of the articles mentioned any long term maternal risks or perinatal complications associated with caesarean section. Fear of pain was the main reported reason why women would prefer to deliver by caesarean section. Conclusions Most of the articles published in Brazilian women’s magazines do not use optimal sources of information. The portrayal of caesarean section is mostly balanced, not explicitly in favour of one or another route of delivery, but incomplete and may be leading women to

    McMorrow, R C N

    2012-02-01

    BACKGROUND: Transversus abdominis plane (TAP) block is an alternative to spinal morphine for analgesia after Caesarean section but there are few data on its comparative efficacy. We compared the analgesic efficacy of the TAP block with and without spinal morphine after Caesarean section in a prospective, randomized, double-blinded placebo-controlled trial. METHODS: Eighty patients were randomized to one of four groups to receive (in addition to spinal anaesthesia) either spinal morphine 100 microg (S(M)) or saline (S(S)) and a postoperative bilateral TAP block with either bupivacaine (T(LA)) 2 mg kg(-1) or saline (T(S)). RESULTS: Pain on movement and early morphine consumption were lowest in groups receiving spinal morphine and was not improved by TAP block. The rank order of median pain scores on movement at 6 h was: S(M)T(LA) (20 mm)groups. Anti-emetic use and pruritus were highest in the S(M)T(LA) group. CONCLUSIONS: Spinal morphine-but not TAP block-improved analgesia after Caesarean section. The addition of TAP block with bupivacaine 2 mg kg(-1) to spinal morphine did not further improve analgesia.

    This introduction sets out the context of the special issue “Karl Marx @ 200: Debating Capitalism & Perspectives for the Future of Radical Theory”, which was published on the occasion of Marx’s bicentenary on 5 May 2018. First, we give a brief overview of contemporary capitalism’s development...... and its crises. Second, we argue that it is important to repeat Marx today. Third, we reflect on lessons learned from 200 years of struggles for alternatives to capitalism. Fourth, we give an overview of the contributions in this special issue. Taken together, the contributions in this special issue show...... that Marx’s theory and politics remain key inspirations for understanding exploitation and domination in 21st-century society and for struggles that aim to overcome these phenomena and establishing a just and fair society. We need to repeat Marx today....

    Caesarean section increases the risk of postpartum infection for women and prophylactic antibiotics have been shown to reduce the incidence; however, there are adverse effects. It is important to identify the most effective class of antibiotics to use and those with the least adverse effects. To determine, from the best available evidence, the balance of benefits and harms between different classes of antibiotic given prophylactically to women undergoing caesarean section. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 September 2014) and reference lists of retrieved papers. We included randomised controlled trials comparing different classes of prophylactic antibiotics given to women undergoing caesarean section. We excluded trials that compared drugs with placebo or drugs within a specific class; these are assessed in other Cochrane reviews. Two review authors independently assessed the studies for inclusion, assessed risk of bias and carried out data extraction. We included 35 studies of which 31 provided data on 7697 women. For the main comparison between cephalosporins versus penicillins, there were 30 studies of which 27 provided data on 7299 women. There was a lack of good quality data and important outcomes often included only small numbers of women.For the comparison of a single cephalosporin versus a single penicillin (Comparison 1 subgroup 1), we found no significant difference between these classes of antibiotics for our chosen most important seven outcomes namely: maternal sepsis - there were no women with sepsis in the two studies involving 346 women; maternal endometritis (risk ratio (RR) 1.11, 95% confidence interval (CI) 0.81 to 1.52, nine studies, 3130 women, random effects, moderate quality of the evidence); maternal wound infection (RR 0.83, 95% CI 0.38 to 1.81, nine studies, 1497 women, random effects, low quality of the evidence), maternal urinary tract infection (RR 1.48, 95% CI 0.89 to 2.48, seven studies, 1120

    Full Text Available OBJECTIVES To study the efficacy of Tranexamic acid in reducing blood loss during and after the lower segment caesarean section in Multigravida parturients. METHODOLOGY A case controlled prospective study was conducted in 50 multigravida parturient women undergoing elective lower segment caesarean section in our hospital after getting Institutional Ethical Committee approval, over a period of two months. 25 of them were given Tranexamic acid 15 mg/kg immediately before caesarean section. Blood loss was collected and measured during two periods. The first period was from placental delivery to end of LSCS and the second from the end LSCS to 2 hours postpartum. RESULTS Tranexamic acid significantly reduces the quantity of blood loss from the end of LSCS to 2 hours post-partum in multigravida parturients. No complications or side effects are noted in both the groups. CONCLUSION Tranexamic acid significantly reduces the amount of blood loss during and after the lower segment caesarean section in multigravida parturients and its use was not associated with any side effects or complications.

    Previous studies examining the efficacy of transversus abdominis plane block after caesarean section have mostly been in parturients under spinal anaesthesia. We postulated that the advantage of performing transversus abdominis plane block after caesarean section might be even more obvious after general anaesthesia, resulting in reduced 24-h consumption of morphine. DESIGN, SETTING, PATIENTS AND INTERVENTIONS: In this single centre, randomised double-blind controlled trial, 40 women who underwent caesarean delivery under general anaesthesia were allocated randomly to receive a transversus abdominis plane block or no block. In those who received the block, 20 ml of levobupivacaine 2.5 mg ml was deposited bilaterally into the transversus abdominis plane under ultrasound guidance using a Sonosite Titan (SonoSite, Bothell, Washington, USA) 7-13 MHz linear transducer at the end of surgery when the patient was still anaesthetised. We recorded patient-controlled intravenous morphine use for 24 h, pain scores at rest and activity, sedation, nausea and vomiting, use of antiemetic medication and overall maternal satisfaction. The primary outcome was 24-h morphine consumption. Patients who received the transversus abdominis plane block used significantly less morphine in 24 h than those in the control group [12.3 (2.6) vs. 31.4 mg (3.1), Pplane block reduced morphine consumption following caesarean section under general anaesthesia, with increased maternal satisfaction.

    Objective: To determine the efficacy of prophylactic administration of intravenous Ondansetron for prevention of spinal anaesthesia induced hypotension in lower segment caesarean section. Study Design: Double blinded randomized controlled trial. Place and Duration of Study: It was conducted in Anesthesiology department, CMH Rawalakot; from 3 Mar to 4 Jun 2014. Material and Methods: One hundred patients were selected for this study, and randomly divided in two groups of 50 each, using random numbers table. Both groups were preloaded with Ringer's lactate at dose of 10ml/kg. Group A received 04 mg of IV ondansetron 5 min prior to spinal anaesthesia, whereas Group B received normal saline 05 minutes before administration of Spinal Anaesthesia. Results: Average age of Group A was 28.62 +- 4.64 years, whereas that of Group B was 27.88 +- 3.98 (p-value= 0.394). Average weight of Group A was 70.30 +- 6.25 kg, whereas that of Group B was 70.74 +- 6.17 kg (p-value= 0.724). Hypotension was noted in 21 patients in group A (42 percent), whereas it was observed in 34 Patients in Group B (68 percent) (p-value= 0.009). Bradycardia was noted in 9 patients in Group A (18 percent) and 19 patients in Group B (p=0.026). Conclusion: Intravenous administration of 04 mg of intravenous ondansetron, 05 minutes prior to subarachnoid block, is effective in decreasing frequency of hypotension. (author)

    To develop a patient decision aid (PtDA) for mode of delivery after caesarean section that integrates personalised prediction of vaginal birth after caesarean (VBAC) with the elicitation of patient preferences and evidence-based information. A PtDA was developed and pilot tested using the International Patients Decision Aid Standards (IPDAS) criteria. Obstetric health care in the Netherlands. A multidisciplinary steering group, an expert panel, and 25 future users of the PtDA, i.e. women with a previous caesarean section. The development consisted of a construction phase (definition of scope and purpose, and selection of content, framework, and format) and a pilot testing phase by interview. The process was supervised by a multidisciplinary steering group. Usability, clarity, and relevance. The construction phase resulted in a booklet including unbiased balanced information on mode of birth after caesarean section, a preference elicitation exercise, and tailored risk information, including a prediction model for successful VBAC. During pilot testing, visualisation of risks and clarity formed the main basis for revisions. Pilot testing showed the availability of tailored structured information to be the main factor involving women in decision-making. The PtDA meets 39 out of 50 IPDAS criteria (78%): 23 out of 23 criteria for content (100%) and 16 out of 20 criteria for the development process (80%). Criteria for effectiveness (n = 7) were not evaluated. An evidence-based PtDA was developed, with the probability of successful VBAC and the availability of structured information as key items. It is likely that the PtDA enhances the quality of decision-making on mode of birth after caesarean section. © 2013 Royal College of Obstetricians and Gynaecologists.

    The purpose of this Roy Adaptation Model-based study was to describe women's physical, emotional, functional and social adaptation; postpartum concerns; and learning needs during the first two weeks following caesarean birth and identify relevant nursing interventions. Studies of caesarean-delivered women indicated a trend toward normalisation of the caesarean birth experience. Escalating caesarean birth rates mandate continued study of contemporary caesarean-delivered women. Mixed methods (qualitative and quantitative) descriptive research design. Nursing students collected data from 233 culturally diverse caesarean-delivered women in urban areas of the Midwestern and Northeastern USA between 2002-2004. The focal stimulus was the planned or unplanned caesarean birth; contextual stimuli were cultural identity and parity. Adaptation was measured by open-ended interview questions, fixed choice questionnaires about postpartum concerns and learning needs and nurse assessment of post-discharge problems. Potential interventions were identified using the Omaha System Intervention Scheme. More positive than negative responses were reported for functional and social adaptation than for physical and emotional adaptation. Women with unplanned caesarean births and primiparous women reported less favourable adaptation than planned caesarean mothers and multiparas. Black women reported lower social adaptation, Hispanic women had more role function concerns and Black and Hispanic women had more learning needs than White women. Post-discharge nursing assessments revealed that actual problems accounted for 40% of identified actual or potential problems or needs. Health teaching was the most commonly recommended postpartum intervention strategy followed by case management, treatment and surveillance interventions. Caesarean-delivered women continue to experience some problems with adapting to childbirth. Recommended intervention strategies reflect the importance of health teaching

    Due to the variety of requirements across aerospace platforms, and one off projects, the repeatability of cryogenic multilayer insulation (MLI) has never been fully established. The objective of this test program is to provide a more basic understanding of the thermal performance repeatability of MLI systems that are applicable to large scale tanks. There are several different types of repeatability that can be accounted for: these include repeatability between identical blankets, repeatability of installation of the same blanket, and repeatability of a test apparatus. The focus of the work in this report is on the first two types of repeatability. Statistically, repeatability can mean many different things. In simplest form, it refers to the range of performance that a population exhibits and the average of the population. However, as more and more identical components are made (i.e. the population of concern grows), the simple range morphs into a standard deviation from an average performance. Initial repeatability testing on MLI blankets has been completed at Florida State University. Repeatability of five Glenn Research Center (GRC) provided coupons with 25 layers was shown to be +/- 8.4% whereas repeatability of repeatedly installing a single coupon was shown to be +/- 8.0%. A second group of 10 coupons has been fabricated by Yetispace and tested by Florida State University, the repeatability between coupons has been shown to be +/- 15-25%. Based on detailed statistical analysis, the data has been shown to be statistically significant.

    This study investigated shoulder pain as a maternal complication after caesarean section (CS), evaluation of its prevalence and comparison between spinal anaesthesia (SA) and general anaesthesia (GA) groups. A total of 200 women as CS candidates were allocated into two equal groups; SA and GA. The total prevalence of shoulder pain was 39.45%. The two groups were matched according to demographic data. However, the incidence of shoulder pain in the GA group was more than that in the SA group (p =0.004). Shoulder pain in the right shoulder in the GA group was more prevalent than the left shoulder (p <0.001). Moderate severity of shoulder pain was significantly more in the GA group (p =0.000), while in the SA group, the mild severity was significant (p <0.001). Our study revealed that the incidence of shoulder pain after CS is significant. Moreover, shoulder pain was significantly more common in the GA group than the SA group.

    The rate of caesarean sections around the world is rising each year, reaching epidemic proportions. Although many caesarean sections are performed for concerns about fetal welfare on the basis of abnormal cardiotocography, the majority of babies are shown to be well at birth, meaning that the operation, with its inherent short and long term risks, could have been avoided without compromising the baby's health. Previously, fetal scalp blood sampling for pH estimation was performed in the context of an abnormal cardiotocograph, to improve the identification of babies in need of expedited delivery. This test has largely been replaced by lactate measurement, although its validity is yet to be established through a randomised controlled trial. This study aims to test the hypothesis that the performance of fetal scalp blood lactate measurement for women in labour with an abnormal cardiotocograph will reduce the rate of birth by caesarean section from 38 % to 25 % (a 35 % relative reduction). Prospective unblinded randomised controlled trial conducted at a single tertiary perinatal centre. Women labouring with a singleton fetus in cephalic presentation at 37 or more weeks' gestation with ruptured membranes and with an abnormal cardiotocograph will be eligible. Participants will be randomised to one of two groups: fetal monitoring by cardiotocography alone, or cardiotocography augmented by fetal scalp blood lactate analysis. Decisions regarding the timing and mode of delivery will be made by the treating team, in accordance with hospital protocols. The primary study endpoint is caesarean section with secondary outcomes collected from maternal, fetal and neonatal clinical course and morbidities. A cost effectiveness analysis will also be performed. A sample size of 600 will provide 90 % power to detect the hypothesised difference in the proportion of women who give birth by caesarean section. This world-first trial is adequately powered to determine the impact of fetal

    Caesarean section is thought to be a risk factor for childhood asthma, but this association may be caused by confounding from, for instance, familial factors. To address this problem, we used twin pairs to assess the risk of childhood asthma after emergency caesarean section. The study was a register-based nation-wide matched cohort study using twin pairs to minimise residual confounding. Included were twin pairs in which the first twin was delivered vaginally and the second by emergency caesarean section during the study period from January 1997 through December 2012. In total, 464 twin pairs (928 twins) were included. In 30 pairs, the first twin (vaginal delivery) was diagnosed with asthma, but the second twin (emergency caesarean section) was not. In 20 pairs, the second twin (emergency caesarean section) was diagnosed with asthma, but the first twin (vaginal delivery) was not. In 11 pairs, both twins developed asthma. In the unadjusted analysis, emergency caesarean section did not affect the risk of asthma (odds ratio = 0.67 (95% confidence interval: 0.38-1.17); p = 0.16). After adjusting for birth weight, gender, umbilical cord pH, Apgar score at 5 min. and neonatal respiratory morbidity, the risk of childhood asthma following emergency caesarean section remained unchanged. Emergency caesarean section was not associated with childhood asthma. none. not relevant.

    The rate of caesarean sections at full cervical dilatation with their high risk of morbidity continues to rise mirroring the overall increase in caesarean section rates internationally. The objectives of this study were to determine the rate of full dilatation caesarean section in a tertiary referral unit and evaluate key labour, maternal and fetal factors potentially linked to those deliveries. We also assessed maternal and fetal morbidity at full dilatation sections. Where possible, these were compared with successful operative vaginal deliveries carried out in theatre to determine key differences. Retrospective cohort study. We reviewed the rate of full dilatation caesarean section over a 10-year period. We analysed deliveries (caesarean sections or operative vaginal deliveries) in single cephalic pregnancies ≥34 weeks with contemporaneously collected data from our unit's electronic database for 2015. The rate of full dilatation caesarean section increased by over a third in the ten-year period (56/6947 (0.80%) vs 92/7378 (1.24%), p = 0.01). Of 84 full dilatation caesarean sections who met the inclusion criteria, 63 (75%) were nulliparous and the mean maternal age was 33 (±5) years. Oxytocin was used in the second stage in less than half of second stage caesarean sections (22 out of a recorded 57, 38.6%). There were more fetal head malposition (occipito-posterior, or occipito-transverse) at full dilatation caesarean section compared to successful operative vaginal deliveries (41/46 (89.1%) vs 2/21 (9.5), p < 0.001). The rate of significant postpartum haemorrhage (defined as estimated blood loss ≥1000 ml) was similar in both full dilatation caesarean section and operative vaginal deliveries. There was no difference in the mean birthweight at full dilatation caesarean sections compared to operative vaginal delivery (3.88 kg (2.80-5.33 kg) vs 3.48 kg (1.53-4.40 kg)).

    To compare the effectiveness of carbetocin with oxytocin with respect to maintain adequate uterine tone and to reduce the incidence and severity of postpartum haemorrhage. Moreover safety, adverse effects and the need of additional medications were evaluated. Prospective controlled clinical trial. We compared the effect of a single dose of carbetocin (n = 55) with oxytocin infusion (n = 55) in a women population undergoing to elective caesarean section with regional subarachnoid anaesthesia with at least one risk factor for postpartum haemorrhage. The mean ± SD of postoperative pain in the day of surgery in carbetocin group was significantly lower than in oxytocin group and remained significant till the third day after caesarean section. In the day of surgery and the first day after surgery, women of carbetocin group who needed analgesic drugs were significantly lower than women of oxytocin group. The differences of diuresis and of diuretic drugs need were not statistically significant between the two groups. A single carbetocin injection is efficacious and safe on the maintenance of uterine tone and on the limitation of blood losses, in peri- and in postoperative period. In addition, carbetocin was able to reduce pain perception during postoperative days improving quality life of women.

    To generate a global reference for caesarean section (CS) rates at health facilities. Cross-sectional study. Health facilities from 43 countries. Thirty eight thousand three hundred and twenty-four women giving birth from 22 countries for model building and 10,045,875 women giving birth from 43 countries for model testing. We hypothesised that mathematical models could determine the relationship between clinical-obstetric characteristics and CS. These models generated probabilities of CS that could be compared with the observed CS rates. We devised a three-step approach to generate the global benchmark of CS rates at health facilities: creation of a multi-country reference population, building mathematical models, and testing these models. Area under the ROC curves, diagnostic odds ratio, expected CS rate, observed CS rate. According to the different versions of the model, areas under the ROC curves suggested a good discriminatory capacity of C-Model, with summary estimates ranging from 0.832 to 0.844. The C-Model was able to generate expected CS rates adjusted for the case-mix of the obstetric population. We have also prepared an e-calculator to facilitate use of C-Model (www.who.int/reproductivehealth/publications/maternal_perinatal_health/c-model/en/). This article describes the development of a global reference for CS rates. Based on maternal characteristics, this tool was able to generate an individualised expected CS rate for health facilities or groups of health facilities. With C-Model, obstetric teams, health system managers, health facilities, health insurance companies, and governments can produce a customised reference CS rate for assessing use (and overuse) of CS. The C-Model provides a customized benchmark for caesarean section rates in health facilities and systems. © 2015 World Health Organization; licensed by John Wiley & Sons Ltd on behalf of Royal College of Obstetricians and Gynaecologists.

Rates of caesarean section are of concern to both developed and developing countries. The indications for caesarean section have been undergoing a gradual change over the last few decades. Besides the obstetric causes, several other medical, social, ethical, economical and medicolegal factors play a role in the rising trend of caesarean section. The aim of the study was undertaken to determine the rate, indications, intraoperative and postoperative complications of primary caesarean section in primi and multipara and maternal and foetal morbidities in these patients. MATERIALS AND METHODS This is a retrospective study carried out on primary caesarean section in the Department of O and G at Mahatma Gandhi Memorial Government Hospital attached to K.A.P.Viswanatham Government Medical College, Trichy, during 1 year period from January 2015-December 2015. Inclusion Criteria- Patients (booked/unbooked attending the labour room undergoing primary caesarean section in the department. Their intraoperative and postoperative complications were noted and also maternal and foetal morbidities and complications. Exclusion Criteria- Gestational age <28 wks., previous LSCS, previous uterine surgery or hysterotomy, multiple gestation. RESULTS There has been a steady increase in total deliveries (increase by 5.2% in the last 2 yrs. at Mahathma Gandhi Memorial Government Hospital attached to K.A.P. Viswanatham Government Medical College, Trichy, and total caesarean section rate (increased by 19.3% and primary caesarean section rate (increased by 12.3% in the past 2 years with concomitant reduction in neonatal mortality rate by 28%. However, this doesn’t justify the increase in primary caesarean section rate. CONCLUSION Potentially modifiable factors such as patient preferences, practice variations among hospitals, systems and

    OBJECTIVE: This study looked at the association between caesarean section (CS) and Body Mass Index (BMI) in primigravidas compared with multigravidas. STUDY DESIGN: We enrolled women at their convenience, in the first trimester after an ultrasound examination confirmed an ongoing pregnancy. Weight and height were measured digitally and BMI calculated. After delivery, clinical details were again collected from the Hospital\\'s computerised database. RESULTS: Of the 2000 women enrolled, there were 50.4% (n=1008) primigravidas and 49.6% (n=992) multigravidas. Of the 2000 8.5% were delivered by elective CS and 13.4% were delivered by emergency CS giving an overall rate of 21.9%. The overall CS rate was 30.1% in obese women compared with 19.2% in the normal BMI category (p<0.001). In primigravidas the increase in CS rate in obese women was due to an increase in emergency CS (p<0.005) and in multigravidas the increase was due to an increase in elective CS (p<0.01). In obese primigravidas 20.6% had an emergency section for fetal distress. In obese multigravidas 17.2% had a repeat elective CS. CONCLUSION: The influence of maternal obesity on the increase in CS rates is different in primigravidas compared with multigravidas.

    Identification of determinants affecting the outcome of external cephalic version (ECV) in breech presentation, and investigation of the impact of ECV--performed according to a standardized protocol in an outpatient clinic--on the mode of delivery. Retrospective analysis. In 2003 a standardized protocol of ECV was developed in the outpatient clinic for obstetrics of the Catharina Hospital in Eindhoven, the Netherlands; it was tested in 'version office visits'. Obstetric characteristics of all pregnant women who underwent attempts of ECV in the clinic from January 2004 until June 2006 during these sessions, and the subsequent births, were analysed. 85% of all ECVs were performed by the same hospital midwife and gynaecologist, in accordance with the protocol. ECV was successful in 96 of 209 pregnant women (46%). In 1 pregnant woman an emergency caesarean section was performed after ECV because of partial abruptio placentae. Nulliparity, incomplete breech presentation and low birth weight of the baby were associated with a lower success rate of ECV in this study. In the group with a successful ECV the percentage of caesarean deliveries was substantially lower (9 versus 83%; odds ratio: 0.21; 95% CI: 0.09-0.51). A regular team consisting of a hospital midwife and a gynaecologist working according to a standardized protocol for ECV in a case of breech presentation proved successful: the number of term breech presentations substantially diminished and therefore the percentage of caesarean sections was lower in the group in which ECV had been successful. This could have considerable impact on health care in the Netherlands in terms of reduced maternal morbidity and cost savings.

    2015-02-05

    BackgroundThe number of caesarean sections (CS) is increasing globally, and repeat CS after a previous CS is a significant contributor to the overall CS rate. Vaginal birth after caesarean (VBAC) can be seen as a real and viable option for most women with previous CS. To achieve success, however, women need the support of their clinicians (obstetricians and midwives). The aim of this study was to evaluate clinician-centred interventions designed to increase the rate of VBAC.MethodsThe bibliographic databases of The Cochrane Library, PubMed, PsychINFO and CINAHL were searched for randomised controlled trials, including cluster randomised trials that evaluated the effectiveness of any intervention targeted directly at clinicians aimed at increasing VBAC rates. Included studies were appraised independently by two reviewers. Data were extracted independently by three reviewers. The quality of the included studies was assessed using the quality assessment tool, `Effective Public Health Practice Project¿. The primary outcome measure was VBAC rates.Results238 citations were screened, 255 were excluded by title and abstract. 11 full-text papers were reviewed; eight were excluded, resulting in three included papers. One study evaluated the effectiveness of antepartum x-ray pelvimetry (XRP) in 306 women with one previous CS. One study evaluated the effects of external peer review on CS birth in 45 hospitals, and the third evaluated opinion leader education and audit and feedback in 16 hospitals. The use of external peer review, audit and feedback had no significant effect on VBAC rates. An educational strategy delivered by an opinion leader significantly increased VBAC rates. The use of XRP significantly increased CS rates.ConclusionsThis systematic review indicates that few studies have evaluated the effects of clinician-centred interventions on VBAC rates, and interventions are of varying types which limited the ability to meta-analyse data. A further limitation is that

    Full Text Available BACKGROUND Awareness during general anaesthesia for caesarean section is a big concern because of its serious adverse consequences. It has been reported that ketamine used as induction agent reduces awareness. This study was conducted to compare awareness under general anaesthesia when thiopentone and ketamine are used as induction agents for caesarean section. MATERIALS AND METHODS Fifty healthy mothers scheduled for elective caesarean section were randomly divided into two groups to receive thiopentone (4 mg/kg -1 or ketamine (1.5 mg/kg -1 for induction of anaesthesia. Mothers were examined for intraoperative awareness using isolated forearm technique until the delivery of the baby. Postoperatively, they were spoken about recall and any hallucination by using a set of questionnaire. RESULTS 15% patients who received thiopentone were able to follow the commands compared to 8% patients who received ketamine. 65% patients who received thiopentone made reaching movements of the isolated forearm towards the stimulus compared to 20% patients of ketamine group. None of the patients in thiopentone group experienced any hallucinations compared to 1 patient (4% in ketamine group who exhibited hallucinations. None of fifty patients could recall the intraoperative events like squeezing of hands or the pain of operation. CONCLUSION Ketamine can be used as substitute for thiopentone as an induction agent in a dose equal to 1.5 mg/kg -1 . Having profound analgesic effect, property to maintain foetoplacental exchange better than any other induction agents, ketamine can be used routinely as an induction agent for mothers undergoing caesarean section under general anaesthesia.

    A head-elevation pillow places a patient in a ramped posture, which maximises the view of the larynx during laryngoscopy, particularly in obese parturients. In our institution an elevation pillow is used pre-emptively for neuraxial anaesthesia. We hypothesised that head-elevation may impair cephalad spread of local anaesthetic before caesarean section resulting in a lower block or longer time to achieve a T6 level. We aimed to investigate the effect of head-elevation on spread of intrathecal local anaesthetics during anaesthesia for caesarean section. One-hundred parturients presenting for caesarean section under combined spinal-epidural anaesthesia were randomised to either the standard supine position with lateral displacement or in the supine position with lateral displacement on an head-elevation pillow. Each patient received intrathecal hyperbaric bupivacaine 11 mg, morphine 100 μg and fentanyl 15 μg. Patients were assessed for adequacy of sensory block (T6 or higher) at 10 min. Sensory block to T6 was achieved within 10 min in 65.9% of parturients in the Elevation Pillow Group compared to 95.7% in the Control Group (P<0.05). Compared to the Control Group, patients in the Elevation Pillow Group had greater requirements for epidural supplementation (43.5% vs 2.1%, P<0.001) or conversion to general anaesthesia (9.3% vs 0%, P<0.04). Use of a ramped position with an head-elevation pillow following injection of the intrathecal component of a combined spinal-epidural anaesthetic for scheduled caesarean section was associated with a significantly lower block height at 10min.

    To establish the degree of variation across hospitals in the use of Caesarean delivery for the indication of labour dystocia before and after accounting for maternal, fetal, and hospital characteristics. This study was a retrospective, population-based cohort study of nulliparous women delivering term singletons in cephalic position following labour. Delivery visits were extracted from three provincial perinatal registries in the Canadian provinces of Ontario, Alberta, and British Columbia, from 2008-2012. Crude hospital-specific rates of Caesarean delivery for labour dystocia were reported, and these rates were then stabilized to account for hospitals with low delivery volumes. Rates were then adjusted for maternal, fetal, and hospital characteristics using hierarchical logistic regression. Among 403 205 women delivering at 170 hospitals, the overall Caesarean delivery rate was 21.0%, and the rate of Caesarean delivery for labour dystocia was 12.7%, indicating that 60% of all Caesarean deliveries were performed in part for this indication. The middle 95% of hospitals had Caesarean delivery rates for labour dystocia ranging from 4.5% to 24.7%. Differences in maternal case mix and hospital characteristics explained only a small proportion of this variation (95% central range 6.3%-21.7%). Considerable inter-hospital variation in rates of Caesarean delivery for labour dystocia remained after accounting for differences in maternal and hospital factors. Reporting systems that monitor variation in inter-institutional rates should incorporate stabilization and adjustment for case-mix differences and consider indication-specific rates of Caesarean delivery to more fairly compare hospital performance and better target interventions to reduce Caesarean delivery for specific indications.

    Full Text Available AIM: We reasoned that addition of musicotherapy -a simple and convenient method with no adverse effects- in the preoperative period would have favorable effects pertaining to postoperative pain. METHODS: One hundred patients, between the ages of 20-40 years, who were undergoing elective caesarean delivery under general anaesthesia, were enrolled. The patients were randomly allocated into two groups (with 50 patients in each and in group 1, patients listened to music through a headphone for one hour immediately before surgery whereas in group 2, patients did not listen to any music during the same period. The anaesthetic technique was standardized. All neonates were also assessed and Apgar scores were recorded. In the postanaesthesia care unit, patients were connected to i.v.-PCA device when they were able to respond to commands. The patient’s level of satisfaction with perioperative care was assessed by a 10-cm visual analogue scale and the severity of postoperative pain was assessed with VAS. RESULTS: Postoperative tramadol consumption, total amount of tramadol consumption, additional analgesic use and all VAS values were lower in group 1 (p<0.05. Apgar scores were significantly greater in group 1. CONCLUSION: We imply that music therapy given before surgery decreases postoperative pain and analgesic requirement.

    2016-10-01

    Full Text Available BACKGROUND Recent trends in obstetric anaesthesia show increased popularity of regional anaesthesia among obstetric anaesthetists. General anaesthesia in caesarean section is associated with high morbidity and mortality rate when compared with regional anaesthesia. Regional anaesthesia has its own demerits which are primarily related to excessively high spinal blocks and toxicity of local anaesthetics. Reduction in doses and improvement in technique to avoid high level blocks and increased awareness of toxicity of local anaesthetics have contributed to reduction in complications related to regional anaesthesia. The challenges presented by a parturient requiring anaesthesia or analgesia, or both, make the role of obstetric anaesthesiologist both challenging and rewarding. Spinal anesthesia is a popular technique for caesarean delivery. Hyperbaric Bupivacaine in 8% glucose is often used. Plain or glucose-free, Bupivacaine has been frequently referred to as “Isobaric” in the literature, even after Blomqvist and Nilsson demonstrated its hypobaricity. More recently, several studies have confirmed that plain Bupivacaine is indeed hypobaric in comparison with human CSF. Although hyperbaric local anesthetic solutions have a remarkable record of safety, their use is not totally without risk. To prevent unilateral or saddle blocks, patients should move from the lateral or sitting position rapidly to supine position. Hyperbaric solutions may cause sudden cardiac arrest after spinal anesthesia because of the extension of the sympathetic block. The use of truly isobaric solutions may prove less sensitive to position issues. Hyperbaric solutions may cause hypotension or bradycardia after mobilization. Isobaric solutions are favored with respect to their less sensitivity to postural changes. MATERIALS AND METHODS 60 full term parturients of ASA Grade 1 and 2 posted for elective caesarean section under spinal anaesthesia were divided in to two groups. GROUP

    Placenta accreta, morbid adherence to the uterus to the myometrium, is commonest in association with placenta previa in women previously delivered by caesarean section (CS). It has become proportionally a greater cause of major maternal morbidity and mortality as the frequency of other serious obstetric complications has declined. The aim of this study was to examine the incidence of placenta accreta in the context of a rising caesarean delivery rate.

    2013-11-01

    the rising trends in caesarean section have been partially attributed to women's requests. Many studies in developed and very few in developing countries have attempted to understand this phenomenon. This qualitative study explores experiences of women having caesarean section on demand in a middle-income country with a private health-care system. an inductive qualitative design, using face-to-face semi-structured interviews. women were identified and recruited through a perinatal database and selected obstetricians' clinics in the Greater Beirut area in Lebanon. a purposive sample of women who had a caesarean childbirth within the four months preceding the interview, were visited for an interview at home using a semi-structured interview guide. Thematic content analysis was conducted on a sub-sample of 22 women who requested a caesarean birth. lack of information about caesarean sections fosters women's fear from labour pain and acts as the main impetus for women to consider caesareans as the pain free alternative. Findings reveal health-care providers' role in reinforcing beliefs about caesarean sections being the way for pain free deliveries by overestimating the safety of the procedure and disregarding postpartum health issues. caesarean birth is presented to women as a safe option for 'pain free' childbirth. This needs to be considered within the cultural context of understanding safety and pain as well as the dynamics of power in maternity care. Health-care professionals need to explore these dimensions and promote women's informed choice as well as encouraging the normality of birth. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Full Text Available Recently two parturients with Eisenmenger's syndrome underwent caesarean section at our hospital. They were managed by a multidisciplinary team during their perioperative period. The caesarean sections were uneventfully performed, one under general anaesthesia and one with epidural anaesthesia, with delivery of two newborns with satisfactory Apgar scores. One patient died in the post-partum period, and the other did well. We discuss the anaesthetic considerations in managing these high-risk patients.

    The aim of this study was to compare the postoperative results of the patients who were treated with Bakri balloon tamponade or hysterectomy for placenta accreta and increta. Patients who were diagnosed with placenta accreta or increta preoperatively and intraoperatively and treated with Bakri balloon tamponade (Group 1) or caesarean hysterectomy (Group 2) were compared in regards to the postoperative results. Among the 36 patients diagnosed with placenta accreta or increta, 19 patients were treated with Bakri balloon tamponade while 17 cases were treated with hysterectomy. Intraoperative blood loss amount was 1794 ± 725 ml in G1, which was lower than that in G2 (2694 ± 893 ml). Blood transfusion amount was 2.7 ± 2.6 units in G1, lower than that in G2 (5.7 ± 2.4 units), too. Operation time was 64.5 ± 29 min and 140 ± 51 min in G1 and G2, respectively, showing significant differences between two groups. The success rate of Bakri balloon was determined as 84.21%. In conclusion, cases with placenta accreta/increta, with predicted placental detachment who are willing to preserve fertility, application of uterine balloon tamponade devices before the hysterectomy is encouraging with its advantages compared with the hysterectomy. Impact statement What is already known on this subject: Invasive placental anomalies are the most common indication of postpartum hysterectomy. Recently, uterine balloon tamponade was also included in the treatment modalities of postpartum haemorrhage.This study aimed to compare the postoperative results of UBT or hysterectomy for patients with placenta accreta and increta. What the results of this study add: In this study, the total amount of blood loss was higher in the caesarean hysterectomy group when compared with the Bakri balloon tamponade group. The mean transfusion requirement, mean operation time and hospitalisation period was significantly longer in the caesarean hysterectomy group. The success

    promoting vaginal births after caesarean section (VBAC) for eligible women and increasing rates of successful VBACs are the best strategies to reduce the number of repeat caesarean sections (CS). Knowledge of factors that are associated with women's decision-making around mode of birth after CS is important when developing strategies to promote VBAC. This study assessed which factors are associated with women's preferences for VBAC versus elective repeat caesarean section (ERCS) in a new pregnancy after one previous caesarean in Switzerland. cross-sectional web-survey. Western Switzerland. French-speaking women living in Western Switzerland, with one previous CS who gave birth subsequently to a child after a complication-free pregnancy were eligible to participate in the survey. Of 393 women who started the survey in November/December 2014, 349 were included: 227 who planned a VBAC and 122 who planned an ERCS at term. univariable and multivariable analyses were conducted to describe and compare women who had planned a VBAC with women who had planned an ERCS in a pregnancy following a CS. Logistic regression modelling was used to investigate predictors that were associated with a preference for a VBAC at term. Analyses were performed with SPSS 22 and Stata 13. of the women planning a VBAC, 62.6% VBAC gave birth vaginally. Predictors which were significantly associated with increased odds of women choosing a VBAC: duration since previous birth in years (OR=1.11 95% CI [1.03-1.20], p=0.010), having had midwifery care during pregnancy (OR=2.09, 95% CI [1.08-4.05], p=0.029), being advised by their healthcare provider to attempt a VBAC (OR=4.20, 95% CI [1.75-10.09], p=0.001), preference for VBAC during the third trimester of their pregnancy (OR=3.98, 95% CI [1.77-8.93], p=0.001), and wishing to let the child choose the moment of birth (OR=1.46, 95% CI[1.22-1.74], p<0.001). The importance of safety for the mother decreased the odds of women preferring a VBAC (OR=0.74, 95

    Upper-arm non-invasive blood pressure measurement during caesarean section can be uncomfortable and unreliable because of movement artefact in the conscious parturient. We aimed to determine whether ankle blood pressure measurement could be used instead in this patient group by comparing concurrent arm and ankle blood pressure measured throughout elective caesarean section under regional anaesthesia in 64 term parturients. Bland-Altman analysis of mean difference (95% limits of agreement [range]) between the ankle and arm was 11.2 (-20.3 to +42.7 [-67 to +102]) mmHg for systolic arterial pressure, -0.5 (-21.0 to +19.9 [-44 to +91]) mmHg for mean arterial pressure and -3.8 (-25.3 to +17.8 [-41 to +94]) mmHg for diastolic arterial pressure. Although ankle blood pressure measurement is well tolerated and allows greater mobility of the arms than measurement from the arm, the degree of discrepancy between the two sites is unacceptable to allow routine use of ankle blood pressure measurement, especially for systolic arterial pressure. However, ankle blood pressure measurement may be a useful alternative in situations where arm blood pressure measurement is difficult or impossible.

    Full Text Available Abstract Objective to compare the distribution of caesarean rates in the Robson's 10 groups classification in order to see if any change occurred after the implementation of an audit and feedback intervention. Design: cross sectional, before and after an audit and feedback study. Setting: a university hospital in Brazil. Methods clinical records of all births during two three months-periods were evaluated. Each case of CS was classified into one of ten mutually exclusive categories according to obstetric characteristics. The proportion of CS in each group was compared in both periods. Results total number of deliveries and the high rate of CS were similar in both periods. Group 3 (multiparous excluding previous CS, single, cephalic, ≥ 37 weeks, spontaneous labour accounted for the largest proportion of deliveries, 28.5 and 26.8% in both periods. Group 1 (nulliparous, single, cephalic, ≥ 37 weeks, spontaneous labour was the second largest one, while Group 5 (previous caesarean section, single, cephalic, and ≥ 37 weeks was the third but the largest contributor to CS, accounting for 16.6 and 14.9% among all deliveries in both periods. Groups 2 (nulliparous, single, cephalic, ≥ 37 weeks, induction or CS before labour and 4 (multiparous excluding previous CS, single, cephalic, ≥ 37 weeks, induction or CS before labour were less prevalent, however had higher rates of CS. Only in Group 10 (All single, cephalic, ≤ 36 weeks, including previous CS, there was a significant decrease of CS rate from 70.5 to 42.6% between periods. Conclusion Robson's classification did not identify any significant change in the pattern of CS rates with the audit and feedback process, but showed to be useful for comparing trends among similar obstetric populations.

    , factors related to infant-care competencies, and some labour and birth outcomes were measured. The largest of the included studies (n = 1275) examined an educational and social support intervention to increase vaginal birth after caesarean section. This high-quality study showed similar rates of vaginal birth after caesarean section in 'verbal' and 'document' groups (relative risk 1.08, 95% confidence interval 0.97 to 1.21). The effects of general antenatal education for childbirth or parenthood, or both, remain largely unknown. Individualized prenatal education directed toward avoidance of a repeat caesarean birth does not increase the rate of vaginal birth after caesarean section.

    Is there an association between Caesarean section and subsequent fertility? There is no or only a slight effect of Caesarean section on future fertility. Previous studies have reported that delivery by a Caesarean section is associated with fewer subsequent pregnancies and longer inter-pregnancy intervals. The interpretation of these findings is difficult because of significant weaknesses in study designs and analytical methods, notably the potential effect of the indication for Caesarean section on subsequent delivery. Retrospective cohort study of 1 047 644 first births to low-risk women using routinely collected, national administrative data of deliveries in English maternity units between 1 April 2000 and 31 March 2012. Primiparous women aged 15-40 years who had a singleton, term, live birth in the English National Health Service were included. Women with high-risk pregnancies involving placenta praevia, pre-eclampsia, eclampsia (gestational or pre-existing), hypertension or diabetes were excluded from the main analysis. Kaplan-Meier analyses and Cox proportional hazard models were used to assess the effect of mode of delivery on time to subsequent birth, adjusted for age, ethnicity, socio-economic deprivation and year of index delivery. Among low-risk primiparous women, 224 024 (21.4%) were delivered by Caesarean section. The Kaplan-Meier estimate of the subsequent birth rate at 10 years for the cohort was 74.7%. Compared with vaginal delivery, subsequent birth rates were marginally lower after elective Caesarean for breech (adjusted hazard ratio, HR 0.96, 95% CI 0.94-0.98). Larger effects were observed after elective Caesarean for other indications (adjusted HR 0.81, 95% CI 0.78-0.83), and emergency Caesarean (adjusted HR 0.91, 95% CI 0.90-0.93). The effect was smallest for elective Caesarean for breech, and this was not statistically significant in women younger than 30 years of age (adjusted HR 0.98, 95% CI 0.96-1.01). We used birth cohorts from maternity

    Full Text Available Setting: The study was conducted in Addis Ababa, the capital city of Ethiopia. Specifically, it was conducted in all healthcare facilities offering maternity and obstetric services. Objective: The objective of the study was to explore the patterns of caesarean-section (CS delivery in Addis Ababa. Methods: A cross-sectional survey was carried out between December 2013 and January 2014. The population for the study were women aged between 15 and 19 years of age who had given birth in the last 1–3 years before the date of data collection. The Census and Survey Processing System software was used for data capturing and analysing both descriptive and inferential statistics using Statistical Package for Social Sciences version 20.0. Results: Amongst the 835 women who delivered at health facilities, 19.2% had given birth by CS. The prevalence of CS based on medical indication was 91.3%. However, 6.9% of CS performed had no medical indication. Private health facilities performed more CSs than public health facilities, 41.1% and 11.7% respectfully. CS was high amongst women of higher socioeconomic standing. Conclusion: Overall, CS deliveries rate in Ethiopia is above the rate recommended by the World Health Organisation. Because socio-economic factors influence CS delivery, governments should play a key role in regulating performance of CSs in private institutions.

    Results from case-control studies have shown an increased risk of acute lymphoblastic leukaemia (ALL) in young children born by caesarean delivery, and prelabour caesarean delivery in particular; however, an association of method of delivery with childhood leukaemia subtypes has yet to be established. We therefore did a pooled analysis of data to investigate the association between childhood leukaemia and caesarean delivery. We pooled data from 13 case-control studies from the Childhood Leukemia International Consortium done in nine countries (Canada, Costa Rica, Egypt, France, Germany, Greece, Italy, New Zealand, and the USA) for births from 1970-2013. We analysed caesarean delivery overall and by indications that probably resulted in prelabour caesarean delivery or emergency caesarean delivery. We used multivariable logistic regression models, adjusted for child's birthweight, sex, age, ethnic origin, parental education, maternal age, and study, to estimate odds ratios (ORs) and 95% CIs for the risk of ALL and acute myeloid leukaemia (AML) in children aged 0-14 years at diagnosis. The studies provided data for 8780 ALL cases, 1332 AML cases, and 23 459 controls, of which the birth delivery method was known for 8655 (99%) ALL cases, 1292 (97%) AML cases, and 23 351 (>99%) controls. Indications for caesarean delivery were available in four studies (there were caesarean deliveries for 1061 of 4313 ALL cases, 138 of 664 AML cases, and 1401 of 5884 controls). The OR for all indications of caesarean delivery and ALL was 1·06 (95% CI 0·99-1·13), and was significant for prelabour caesarean delivery and ALL (1·23 [1·04-1·47]; p=0·018). Emergency caesarean delivery was not associated with ALL (OR 1·02 [95% CI 0·81-1·30]). AML was not associated with caesarean delivery (all indications OR 0·99 [95% CI 0·84-1·17]; prelabour caesarean delivery 0·83 [0·54-1·26]; and emergency caesarean delivery 1·05 [0·63-1·77]).

    Sterile water injections have been used as an effective intervention for the management of back pain during labour. The objective of the current research is to determine if sterile water injections, as an intervention for back pain in labour, will reduce the intrapartum caesarean section rate. A double blind randomised placebo controlled trialSetting: Maternity hospitals in AustraliaParticipants: 1866 women in labour, ≥18 years of age who have a singleton pregnancy with a fetus in a cephalic presentation at term (between 37 + 0 and 41 + 6 weeks gestation), who assess their back pain as equal to or greater than seven on a visual analogue scale when requesting analgesia and able to provide informed consent. Participants will be randomised to receive either 0.1 to 0.3 millilitres of sterile water or a normal saline placebo via four intradermal injections into four anatomical points surrounding the Michaelis' rhomboid over the sacral area. Two injections will be administered over the posterior superior iliac spine (PSIS) and the remaining two at two centimetres posterior, and one centimetre medial to the PSIS respectively. Proportion of women who have a caesarean section in labour.Randomisation: Permuted blocks stratified by research site.Blinding (masking):Double-blind trial in which participants, clinicians and research staff blinded to group assignment. Funded by the National Health and Medical Research CouncilTrial registration:Australian New Zealand Clinical Trials Registry (No ACTRN12611000221954). Sterile water injections, which may have a positive effect on reducing the CS rate, have been shown to be a safe and simple analgesic suitable for most maternity settings. A procedure that could reduce intervention rates without adversely affecting safety for mother and baby would benefit Australian families and taxpayers and would reduce requirements for maternal operating theatre time. Results will have external validity, as the technique may be easily applied to

    Multiple studies suggest that transversus abdominis plane (TAP) block (without intrathecal morphine) after Caesarean section (CS) reduces post-operative morphine consumption. In our study, we wanted to compare the analgesic effect of TAP block with infiltration of the wound after CS. We included 60 pregnant women scheduled for elective CS under spinal anaesthesia in a randomised, single-centre, double-blind study. Thirty patients received ultrasound-guided TAP block using 20 ml bupivacaine 0.25% with adrenaline 5 μg/ml bilaterally and 20 ml normal saline as wound infiltration (TAP group). The other 30 patients (the control group) received normal saline 20 ml bilaterally in the TAP, and 20 ml bupivacaine 0.25% with adrenaline 5 μg/ml as wound infiltration. The main outcome was cumulative morphine consumption at 48 h after surgery. In addition, continuous morphine consumption, pain scores and side effects were registered. Fifty-seven patients completed the study. Cumulative morphine consumption at 48 h (mean±standard deviation) was 41±34 mg in the TAP group and 38±27 mg in the control group (P=0.7); a difference of 3 mg (95% confidence interval -13 to 19 mg). Morphine consumption at any time up to 48 h was virtually identical in both groups. Side effects were similar, except for a higher degree of sedation in the TAP group (P=0.04). Compared with wound infiltration with local anaesthetics, TAP block did not reduce cumulative morphine consumption following CS. The TAP block was associated with more pronounced sedation. © 2015 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

    Caesarean delivery carries a risk of major intra-operative blood loss and its performance is often delayed by non-availability of blood and blood products. Unnecessary cross-matching and reservation of blood lead to apparent scarcity in centres with limited supply. This study set out to identify the risk factors for blood transfusion in women who underwent caesarean delivery at a tertiary obstetric unit with a view to ensuring efficient blood utilization. A prospective cohort analysis of 906 women who had caesarean deliveries at the Lagos State University Teaching Hospital, Nigeria between January and December, 2011. A comparison was made between 188 women who underwent blood transfusion and 718 who did not. Data were obtained on a daily basis by investigators from patients, clinical notes and referral letters using structured pre-tested data collecting form. Socio-demographic characteristics; antenatal, perioperative and intraoperative details; blood loss; transfusion; and puerperal observations were recorded. EPI-Info statistical software version 3.5.3 was used for multivariable analysis to determine independent risk factors for blood transfusion. Of the 2134 deliveries during the study period, 906 (42.5%) had caesarean deliveries and of which 188 (20.8%) were transfused. The modal unit of blood transfused was 3 pints (41.3%). The most common indication for caesarean section was cephalo-pelvic disproportion (25.7%).The independent risk factors for blood transfusion at caesarean section were second stage Caesarean Section (aOR = 76.14, 95% CI = 1.25-4622.06, p = 0.04), placenta previa (aOR = 32.57, 95% CI = 2.22-476.26, p = 0.01), placental abruption (aOR = 25.35, 95% CI = 3.06-211.02, p blood transfusion (aOR = 0.24, 95% CI = 0.09-0.61, p = 0.0024).

    Bangladesh has a high level of maternal mortality, corresponding to one of the world's lowest rates of use of skilled birth attendance (12.1%), and a similarly low rate of caesarean births (2.4%). While increasing the proportion of women who deliver with professional medical care is essential to prevent maternal deaths, past work has identified distrust of caesarean procedures in Bangladesh. The reasons behind this distrust can manifest itself in health seeking behaviour around maternal care. This paper presents findings from a qualitative study of 30 women in a rural district of Bangladesh who recently delivered in a health facility. It finds that the distrust in doctor's recommendations for surgery stemmed from high costs incurred and a belief that it was used when not medically justified. This could lead to women avoiding or leaving medical facilities in extreme cases. Some women's experiences further illustrated disagreement among medical staff as to whether or not a caesarean procedure should be done, with conflicting financial incentives for doctors to perform caesarean deliveries, and for nurses and midwives to conduct normal deliveries. Policy makers must recognise that the fears women hold of caesarean deliveries may not simply be rooted in ignorance and may, in fact, reflect legitimate concerns with medical practice. Ultimately, it will be essential to address problems in the health systems environment, which may promote improper service provision.

    Empowering surgical nurses improves compliance rates for antibiotic prophylaxis after caesarean birth. This paper is a report of a study of the effect of empowering surgical nurses to ensure that patients receive antibiotic prophylaxis after caesarean birth. Despite the consensus that single dose antibiotic prophylaxis is beneficial for women have either elective or non-elective caesarean delivery, hospitals need methods to increase compliance rates. In a study in Israel in 2007 surgical nurses were empowered to ensure that a single dose of cefazolin was given to the mother after cord clamping. A computerized system was used to identify women having caesarean births, cultures sent and culture results. Compliance was determined by chart review. Rates of compliance, suspected wound infections, and confirmed wound infections in 2007 were compared to rates in 2006 before the policy change. Relative risks were calculated dividing 2007 rates by those in 2006, and 95% confidence intervals were calculated using Taylor's series that does not assume a normal distribution. Statistical significance was assessed using the chi-square test. The compliance rate was increased from 25% in 2006 to 100% in 2007 (chi-square test, P rates decreased from 16.8% (186/1104) to 12.6% (137/1089) after the intervention (relative risk 0.75, 95% confidence interval, 0.61-0.92). Surgical nurses can ensure universal compliance for antibiotic prophylaxis in women after caesarean birth, leading to a reduction in wound infections.

    Previous exposure to antibiotics has been associated with the pathogenesis of several autoimmune diseases. Our objective was to explore whether childhood exposure to antibiotics would be associated with the risk of developing juvenile idiopathic arthritis (JIA). The material was collected from national registers containing all children born in 2000-2010 in Finland and diagnosed with JIA by the end of December 2012 (n = 1298) and appropriate controls (n = 5179) matched for age, sex, and place of birth. All purchases of antibiotics were collected from birth until the index date (i.e., the date of special reimbursement for JIA medications). A conditional logistic regression was performed to evaluate the association between the exposure to antibiotics and the risk of JIA. The risk of JIA increased with the number of antibiotic purchases from birth to the index date: for ≥ 1 purchases versus none, OR 1.6, 95% CI 1.3-1.9 with an upward trend in OR (p Antibiotic groups lincosamides and cephalosporins showed the strongest association with JIA (OR 6.6, 95% CI 3.7-11.7, and OR 1.6, 95% CI 1.4-1.8, respectively). Overall exposure to antibiotics before 2 years of age was associated with an increased risk of JIA (OR 1.4, 95% CI 1.2-1.6), with the trend test of OR (p antibiotics may predispose individuals to develop JIA. Alternatively, the apparent association may reflect shared susceptibility to infections and JIA.

    Preventative psychological interventions to aid women after traumatic childbirth are needed. This proof-of-principle randomized controlled study evaluated whether the number of intrusive traumatic memories mothers experience after emergency caesarean section (ECS) could be reduced by a brief cognitive intervention. 56 women after ECS were randomized to one of two parallel groups in a 1:1 ratio: intervention (usual care plus cognitive task procedure) or control (usual care). The intervention group engaged in a visuospatial task (computer-game 'Tetris' via a handheld gaming device) for 15 min within six hours following their ECS. The primary outcome was the number of intrusive traumatic memories related to the ECS recorded in a diary for the week post-ECS. As predicted, compared with controls, the intervention group reported fewer intrusive traumatic memories (M = 4.77, SD = 10.71 vs. M = 9.22, SD = 10.69, d = 0.647 [95% CI: 0.106, 1.182]) over 1 week (intention-to-treat analyses, primary outcome). There was a trend towards reduced acute stress re-experiencing symptoms (d = 0.503 [95% CI: -0.032, 1.033]) after 1 week (intention-to-treat analyses). Times series analysis on daily intrusions data confirmed the predicted difference between groups. 72% of women rated the intervention "rather" to "extremely" acceptable. This represents a first step in the development of an early (and potentially universal) intervention to prevent postnatal posttraumatic stress symptoms that may benefit both mother and child.

The objectives of this study were to compare postoperative pain, wound healing based on wound evaluation scale (WES, wound cosmetic appearance based on visual analogue scale (VAS scores and patient satisfaction score (PSS, and safety profiles between C. striatus group and placebo group after six weeks of lower segment caesarean section (LSCS delivery. A randomised, double-blind, placebo-controlled study was conducted. Subjects were randomised in a ratio of 1 : 1 into either the C. striatus group (500 mg daily or placebo group (500 mg of maltodextrin daily. 76 subjects were successfully randomised, with 38 in the C. striatus group and 35 in the placebo group. There were no significant differences in postoperative pain p=0.814 and WES p=0.160 between the C. striatus and placebo groups. However, VAS and PSS in the C. striatus group were significantly better compared with the placebo group (p=0.014 and p<0.001, resp.. The safety profiles showed no significant differences between the groups. In conclusion, six-week supplementation of 500 mg of C. striatus extract showed marked differences in wound cosmetic appearance and patient’s satisfaction and is safe for human consumption.

    This study reviewed caesarean sections for very low birth weight babies in a tertiary referral maternity hospital. Maternal and neonatal complications were recorded and classified according to uterine incision type. We reviewed medical records of 89 women over a period of 2 years. The indication for the caesarean section influenced the type of uterine incision made (p = 0.004). Women who had antepartum haemorrhage were more likely to need a vertical incision. There was also a higher incidence of vertical incisions for gestations <28 weeks (p = 0.029). Surprisingly, when the computerised discharge summaries were reviewed retrospectively, all the vertical uterine incisions were recorded as lower segment caesarean sections. This would have a clinical impact on those women in future pregnancies, especially in a highly mobile population.

    Full Text Available The caesarean delivery (CD rate has risen in most countries over the last decades, but it remains relatively low in the Netherlands. Our objective was to analyse the trends of CD rates in various subgroups of women between 2000 and 2010, and identify the practice pattern that is attributable to the relative stability of the Dutch CD rate.A total of 1,935,959 women from the nationwide Perinatal Registry of the Netherlands were included. Women were categorized into ten groups based on the modified CD classification scheme. Trends of CD rates in each group were described.The overall CD rate increased slightly from 14.0% in 2000-2001 to 16.7% in 2010. Fetal, early and late neonatal mortality rates decreased by 40-50% from 0.53%, 0.21%, 0.04% in 2000-2001 to 0.29%, 0.12%, 0.02% in 2010, respectively. During this period, the prevalence of non-vertex presentation decreased from 6.7% to 5.3%, even though the CD rate in this group was high. The nulliparous women with spontaneous onset of labor at term and a singleton child in vertex presentation had a CD rate of 9.9%, and 64.7% of multiparous women with at least one previous uterine scar and a singleton child in vertex presentation had a trial of labor and the success rate of vaginal delivery was 45.9%.The Dutch experience indicates that external cephalic version for breech presentation, keeping the CD rate low in nulliparous women and encouraging a trial of labor in multiparous women with a previous scar, could help to keep the overall CD rate steady.

    Full Text Available Abstract:Background:A systematic review concluded that a caesarean section that is performed for medical indications will save lives, but is associated with short and long term complications. The caesarean section rate at CHBAH was 39.78% in 2015. Objectives:To evaluate the indications for caesarean section.Methods:This was a cross-sectional study  in the week 23rd June to the 29th June 2015. Each file was  evaluated for the  correctness of the decision by at least two researchers. Each reviewer could state that he/she absolutely agreed, partially agreed, did not agree or could not make an assessmen.Results:The mean age was 27.01 (6.35; range- 15-44. The median parity was 1(IQR=0-2; range=0-4. No co-morbdities was found in 20 (13.61%. Complications occurred in 25 (17.01% women. The median gestational age at delivery was 38.14 (IQR=36.39-40.14; range-28.0-42.4. The median Apgar (5 min was 10 (IQR=9-10; range- 0-10. The median birth weight was 3040 g (IQR=2530-3440; range- 825-4575 g. The most common indications were fetal distress (n=73; 49.66% and dystocia (n=42; 28.57%. There was absolute agreement between the 2 reviewers in the following; retained 2nd twin, APH of unknown origin, placenta previa, severe IUGR, multiple pregnancy, abnormal presentation, eclampsia, two caesarean sections. When the indication was fetal distress, dystocia, 2nd stage caesarean section, or with 1 previous caesarean the absolute agreement was between 73.85% and 90.24%.Conclusion:There were  few absolute disagreements with the indication. There needs to be an evaluation of methods to diagnose fetal distress and dystocia.

    Birth cohort studies in some countries have shown a link between caesarean section and asthma. To determine if there is an association between asthma and delivery via caesarean section in Malaysian children. This is a case-control study involving 156 children aged 3-15 years old, in a tertiary hospital in Kuala Lumpur, Malaysia. Seventy-eight children with a confirmed diagnosis of asthma and seventy-eight age-matched controls (no history of asthma or wheezing) were enrolled. Demographic data including mode of delivery and family history of allergic disorders was obtained. Total serum immunoglobulin E (IgE) was measured and skin prick tests (SPT) to 6 common aeroallergens were performed. The median age of the patients was 8 years old. One hundred and three (66%) children were delivered via normal vaginal delivery, 8 (5.1%) via assisted vaginal delivery and 45 children (28.9%) via caesarean section. Delivery via caesarean section was not significantly associated with asthma (OR = 1.21 [95% CI 0.60-2.41], p = 0.596). Children delivered via caesarean section did not have higher IgE levels nor were they more sensitized to aeroallergens. Multiple logistic regression showed that asthma was significantly associated with a positive family history of atopy (OR = 13.8 [95% CI 5.96, 32.1], p food after 6 months old had a protective effect against asthma (OR = 0.97 [95% CI 0.94, 0.99], p = 0.034). Childhood asthma in Malaysian children was not associated with delivery by caesarean section.

    Full Text Available Even though the caesarean section is an essential component of comprehensive obstetric and newborn care for reducing maternal and neonatal mortality, there is a lack of data regarding caesarean section rates, its determinants and health outcomes among tribal communities in India.The aim of this study is to estimate and compare rates, determinants, indications and outcomes of caesarean section. The article provides an assessment on how the inequitable utilization can be addressed in a community-based hospital in tribal areas of Gujarat, India.Prospectively collected data of deliveries (N = 19923 from April 2010 to March 2016 in Kasturba Maternity Hospital was used. The odds ratio of caesarean section was estimated for tribal and non-tribal women. Decomposition analysis was done to decompose the differences in the caesarean section rates between tribal and non-tribal women.The caesarean section rate was significantly lower among tribal compared to the non-tribal women (9.4% vs 15.6%, p-value < 0.01 respectively. The 60% of the differences in the rates of caesarean section between tribal and non-tribal women were unexplained. Within the explained variation, the previous caesarean accounted for 96% (p-value < 0.01 of the variation. Age of the mother, parity, previous caesarean and distance from the hospital were some of the important determinants of caesarean section rates. The most common indications of caesarean section were foetal distress (31.2%, previous caesarean section (23.9%, breech (16% and prolonged labour (11.2%. There was no difference in case fatality rate (1.3% vs 1.4%, p-value = 0.90 and incidence of birth asphyxia (0.3% vs 0.6%, p-value = 0.26 comparing the tribal and non-tribal women.Similar to the prior evidences, we found higher caesarean rates among non-tribal compare to tribal women. However, the adverse outcomes were similar between tribal and non-tribal women for caesarean section deliveries.

    External cephalic version (ECV) reduces the incidence of breech presentation at term and caesarean section for non-cephalic births. Tocolytics may improve success rates, but are time consuming, may cause side effects and have not been proven to alter caesarean section rates. The aim of this trial was to determine whether tocolysis should be used if ECV is being re-attempted after a failed attempt. To determine whether tocolysis should be used if ECV is being re-attempted after a failed attempt. Randomised, double-blinded, placebo-controlled trial. UK teaching hospital. One hundred and twenty-four women with a breech presentation at term who had undergone an unsuccessful attempt at ECV. Relative risks with 95% confidence intervals for categorical variables and a t test for continuous variables. Analysis was by intention to treat. Incidence of cephalic presentation at delivery. Secondary outcomes were caesarean section and measures of neonatal and maternal morbidity. The use of tocolysis for a repeat attempt at ECV significantly increases the incidence of cephalic presentation at delivery (RR 3.21; 95% CI 1.23-8.39) and reduces the incidence of caesarean section (RR 0.33; 95% CI 0.14-0.80). The effects were most marked in multiparous women (RR for cephalic presentation at delivery 9.38; 95% CI 1.64-53.62). Maternal and neonatal morbidity remain unchanged. The use of tocolysis increases the success rate of repeat ECV and reduces the incidence of caesarean section. A policy of only using tocolysis where an initial attempt has failed leads to a relatively high success rate with minimum usage of tocolysis.

Cases were validated by review of medical records and 53 cases with prior CD, trial of labour, available cardiotocogram (CTG and complete uterine rupture were included and compared with 43 controls with prior CD, trial of labour and available CTG. The CTG tracings were assessed by 19 independent experts divided into groups of three different experts for each tracing. The assessors were blinded to group, outcome and clinical data. They analyzed occurrence of defined abnormalities and classified the traces as normal, suspicious, pathological or pre-terminal according to international guidelines (FIGO.A pathological CTG during the first stage of labour was present in 77% of cases and in 53% of the controls (OR 2.58 [CI: 0.96-6.94] P = 0.066. Fetal tachycardia was more frequent in cases with uterine rupture (OR 2.50 [CI: 1.0-6.26] P = 0.053. Significantly more cases showed more than 10 severe variable decelerations compared with controls (OR 22 [CI: 1.54-314.2] P = 0.022. Uterine tachysystole was not correlated with the presence of uterine rupture.A pathological cardiotocogram should lead to particular attention on threatening uterine rupture but cannot be considered a strong predictor as it is common in all women with trial of labour after caesarean delivery.

  13. Repeated DNA sequences in fungi

    1974-11-01

    Several fungal species, representatives of all broad groups like basidiomycetes, ascomycetes and phycomycetes, were examined for the nature of repeated DNA sequences by DNA:DNA reassociation studies using hydroxyapatite chromatography. All of the fungal species tested contained 10 to 20 percent repeated DNA sequences. There are approximately 100 to 110 copies of repeated DNA sequences of approximately 4 x 10/sup 7/ daltons piece size of each. Repeated DNA sequence homoduplexes showed on average 5/sup 0/C difference of T/sub e/50 (temperature at which 50 percent duplexes dissociate) values from the corresponding homoduplexes of unfractionated whole DNA. It is suggested that a part of repetitive sequences in fungi constitutes mitochondrial DNA and a part of it constitutes nuclear DNA. (auth)

    We describe the anaesthetic management of a patient with Liddle\\'s syndrome during caesarean section and emergency hysterectomy for placenta accreta associated with significant intrapartum haemorrhage. Liddle\\'s syndrome is a rare autosomal dominant disorder characterised by early onset arterial hypertension and hypokalaemic metabolic alkalosis. Additional issues were the presence of short stature, limb hypertonicity and preeclampsia. Initial management with a low-dose combined spinal-epidural technique was subsequently converted to general anaesthesia due to patient discomfort. The management of Liddle\\'s syndrome in the setting of neuraxial and general anaesthesia in a patient undergoing caesarean section is discussed.

    Objective: To assess efficacy of colloid (Polygeline) over crystalloid (Lactated Ringer) preloading in preventing hypotension in patients undergoing caesarean-section under spinal anaesthesia. Study design: Randomized control trial. Settings: The study was conducted in department of Anesthesiology and Intensive care Combined Military Hospital Peshawar over a period of 6 months from 01 March 2007 to 31 August 2007. Material and Methods: One hundred patients fulfilling the inclusion criteria were selected for study and divided into two groups of 50 each. Group A was given 500 ml Polygeline as preloading solution while group B received 1 liter of Ringer's Lactate as preloading solution just before administration of spinal anaesthesia. Heart rate and systolic blood pressure were recorded at 01 min, 05 mins, 10 mins, 15 mins, 20 mins, 30 mins and 45 mins after the performance of spinal block. Dose of ephedrine given to treat hypotension after the block was also recorded. Results: There was significant difference in terms of heart rate and systolic arterial pressure 1 and 5 minutes after block between both the groups. There was also significant difference in terms of dose of ephedrine between both the groups. Conclusion: Polygeline is more effective than Ringer's Lactate as preloading fluid in preventing hypotension for caesarean section under spinal anaesthesia. (author)

    To examine how the relaxation of the one child policy and policies to reduce caesarean section rates might have affected trends over time in caesarean section rates and perinatal and pregnancy related mortality in China. Observational study. China's National Maternal Near Miss Surveillance System (NMNMSS). 6 838 582 births at 28 completed weeks or more of gestation or birth weight ≥1000 g in 438 hospitals in the NMNMSS between 2012 and 2016. Obstetric risk was defined using a modified Robson classification. The main outcome measures were changes in parity and age distributions and relative frequency of each Robson group, crude and adjusted trends over time in caesarean section rates within each risk category (using Poisson regression with a robust variance estimator), and trends in perinatal and pregnancy related mortality over time. Caesarean section rates declined steadily between 2012 and 2016 (crude relative risk 0.91, 95% confidence interval 0.89 to 0.93), reaching an overall hospital based rate of 41.1% in 2016. The relaxation of the one child policy was associated with an increase in the proportion of multiparous births (from 34.1% in 2012 to 46.7% in 2016), and births in women with a uterine scar nearly doubled (from 9.8% to 17.7% of all births). Taking account of these changes, the decline in caesarean sections was amplified over time (adjusted relative risk 0.82, 95% confidence interval 0.81 to 0.84). Caesarean sections declined noticeably in nulliparous women (0.75, 0.73 to 0.77) but also declined in multiparous women without a uterine scar (0.65, 0.62 to 0.77). The decrease in caesarean section rates was most pronounced in hospitals with the highest rates in 2012, consistent with the government's policy of targeting hospitals with the highest rates. Perinatal mortality declined from 10.1 to 7.2 per 1000 births over the same period (0.87, 0.83 to 0.91), and there was no change in pregnancy related mortality over time. China is the only country that

    Caesarean section was initially performed to save the lives of the mother and/or her baby. Caesarean section rates have risen substantially worldwide over the past decades. In this study, we set out to compile all available caesarean section rates worldwide at the country level, and to identify the appropriate caesarean section rate at the population level associated with the minimal maternal and neonatal mortality. Ecological study using longitudinal data. Worldwide country-level data. A total of 159 countries were included in the analyses, representing 98.0% of global live births (2005). Nationally representative caesarean section rates from 2000 to 2012 were compiled. We assessed the relationship between caesarean section rates and mortality outcomes, adjusting for socio-economic development by means of human development index (HDI) using fractional polynomial regression models. Maternal mortality ratio and neonatal mortality rate. Most countries have experienced increases in caesarean section rate during the study period. In the unadjusted analysis, there was a negative association between caesarean section rates and mortality outcomes for low caesarean section rates, especially among the least developed countries. After adjusting for HDI, this effect was much smaller and was only observed below a caesarean section rate of 5-10%. No important association between the caesarean section rate and maternal and neonatal mortality was observed when the caesarean section rate exceeded 10%. Although caesarean section is an effective intervention to save maternal and infant lives, based on the available ecological evidence, caesarean section rates higher than around 10% at the population level are not associated with decreases in maternal and neonatal mortality rates, and thus may not be necessary to achieve the lowest maternal and neonatal mortality. The caesarean section rate of around 10% may be the optimal rate to achieve the lowest mortality. © 2015 The Authors

    Most African countries are challenged in recruiting and retaining voluntary blood donors by cost and other complexities and in establishing and implementing national blood policies. The availability of replacement donors who are a cheaper source of blood has not enhanced repeat voluntary donor initiatives. An overview of activities for recruiting and retaining voluntary blood donors was carried out. Donor records from mobile sessions were reviewed from 2002 to 2008. A total of 71,701 blood donations; 45,515 (63.5%) being voluntary donations with 11,680 (25%) repeat donations were collected during the study period. Donations from schools and colleges contributed a steady 60% of total voluntary whilst radio station blood drives increased contribution from 10 to 27%. Though Muslim population is less than 20%, blood collection was above the 30-donation cost-effectiveness threshold with a repeat donation trend reaching 60%. In contrast Christian worshippers provided donations. Repeat donation trends amongst school donors and radio blood drives were 20% and 70% respectively. Repeat donations rates have been variable amongst different blood donor groups in Kumasi, Ghana. The impact of community leaders in propagating altruism cannot be overemphasized. Programs aiming at motivating replacement donors to be repeat donors should be developed and assessed. Copyright 2009 The International Association for Biologicals. All rights reserved.

    to assess the association between non-clinical factors and the incidence of caesarean section (CS); to estimate the effect of a prenatal instructor's presence during childbirth on birth outcome (vaginal or CS). cross-sectional study from a register of women who attended prenatal classes. Multivariate logistic regression was used to measure the effects of each variable on whether the birth was vaginal or CS. Mexico City, Mexico. 992 births to 847 women from the register of the Birth Education Centre (CEPAPAR) between 1987 and 2000. the incidence of CS was 33%. The most commonly reported (by the women) reason for performing a CS was dystocia (53%). Most women were middle or upper-middle class professionals, and 85% of the women gave birth in private institutions. Odds of having a CS were higher among women who gave birth in a large hospital, women who were over 25 years of age, primigravidae, and women who were not supported by a prenatal instructor during childbirth. non-clinical factors considerably affect the type of birth outcome (vaginal vs. CS). A system in which a prenatal instructor provided support to the woman during childbirth could contribute significantly to reducing initial and repeat CS.

    Background: Ante partum haemorrhage remains to be a major cause of morbidity and mortality. 30 percentage of this haemorrhage is attributed to placental abruption. Along with other adverse maternal outcomes, it increases the risk of Caesarean sections in patients, which is a public health concern. This study was conducted to find out whether any significant association exists between placental abruption and C-section in our set up. Methods: A cross-sectional study was conducted from July 26th, 2011 to May 1st, 2013 (i.e., 21 months) in the Department of Obstetrics and Gynaecology, Khyber Teaching Hospital Peshawar on a sample of 334 patients who presented with antepartum haemorrhage after 28 weeks of gestation. All those patients with and without placental abruption were followed throughout pregnancy and labour to detect the risk of caesarean section. Results: Among study participants, parity had the highest dispersion while gestational age had the lowest. Caesarean section was performed on 26.3 percentage (95 percentage CI) of the study participants. Proportion of placental abruption among patients presenting with ante partum haemorrhage was 20.6 percentage, (95 percentage CI) out of which 7.5 percentage underwent C-section. Association between placental abruption and C-section was found significant at a=0.05 (ρ=0.03). Conclusion: Risk of caesarean section is increased in pregnancies complicated by placental abruption as compared to pregnancies complicated by other causes of ante partum haemorrhage. (author)

    Caesarean section (CS) is a common surgical procedure. Although it has been performed in a modern context for about 100 years, there is no concise analysis of the international architecture of caesarean section research output available so far. Therefore, the present study characterizes the global pattern of the related publications by using the NewQIS (New Quality and Quantity Indices in Science) platform, which combines scientometric methods with density equalizing mapping algorithms. The Web of Science was used as a database. 12,608 publications were identified that originated from 131 countries. The leading nations concerning research activity, overall citations and country-specific h-Index were the USA and the United Kingdom. Relation of the research activity to epidemiologic data indicated that Scandinavian countries including Sweden and Finland were leading the field, whereas, in relation to economic data, countries such as Israel and Ireland led. Semi-qualitative indices such as country-specific citation rates ranked Sweden, Norway and Finland in the top positions. International caesarean section research output continues to grow annually in an era where caesarean section rates increased dramatically over the past decades. With regard to increasing employment of scientometric indicators in performance assessment, these findings should provide useful information for those tasked with the improvement of scientific achievements.

    Full Text Available Abstract Background Post caesarean wound infection is not only a leading cause of prolonged hospital stay but a major cause of the widespread aversion to caesarean delivery in developing countries. In order to control and prevent post caesarean wound infection in our environment there is the need to access the relative contribution of each aetiologic factor. Though some studies in our environment have identified factors associated with post caesarean wound infection, none was specifically designed to address these issues prospectively or assess the relative contribution of each of the risk factors. Findings Prospective multicentre study over a period of 56 months in Lagos Nigeria. All consecutive and consenting women scheduled for caesarean section and meeting the inclusion criteria were enrolled into the study. Cases were all subjects with post caesarean wound infection. Those without wound infection served as controls. Data entry and analysis were performed using EPI-Info programme version 6 and SPSS for windows version 10.0. Eight hundred and seventeen women were enrolled into the study. Seventy six (9.3% of these cases were complicated with wound infection. The proportion of subjects with body mass index greater than 25 was significantly higher among the subjects with wound infection (51.3% than in the subjects without wound infection (33.9% p = 0.011. There were also significantly higher proportions of subjects with prolonged rupture of membrane (p = 0.02, prolonged operation time (p = 0.001, anaemia (p = 0.031 and multiple vaginal examinations during labour (0.021 among the women that had wound infection compared to the women that did not have wound infection. After adjustment for confounders only prolonged rupture of membrane (OR = 4.45, prolonged operation time (OR = 2.87 and body max index > 25 (2.34 retained their association with post caesarean wound infection. Conclusion Effort should be geared towards the prevention of prolonged

    Pregnancy- and childbirth-related fears are common psychological concerns and the primary reasons for requesting caesarean section (CS). We aimed to examine the content of maternal fear and the associated demographic factors in a sample of Iranian primigravidae. A randomly selected sample of primigravidae (n = 342) was recruited in four health care centres in Iran. Data were collected using a 30-item questionnaire. Principal components factor analysis was applied to identify the main factors of pregnancy- and childbirth-related fears. All primigravidae reported some degree of fear, 48.2 % presented severe fear, and 62.6 % requested a CS because of childbirth-related fear. Most of the employed primigravidae with higher education level, higher family income, and unplanned pregnancy requested CS. The items constructed to measure maternal fear were subjected to exploratory factor analysis. Six categories were identified, including 'process of labour and childbirth', 'life and well-being of the baby', 'competence and behaviour of maternity ward personnel', 'own capabilities and reactions', 'becoming a parent and family life after delivery' and 'general fear in pregnancy' that cumulatively explained 55.3 % of the variance. The most common factor was 'life and well-being of the baby'. Severe fear was found in 70.6 % of those who chose CS, while 10.9 % of those who chose vaginal delivery reported severe fear. The between-group differences for mean scores and levels of fear were statistically significant. Pregnancy- and childbirth-related fears were frequently experienced by all low-risk primigravidae. Better strategies to address women's psychological needs during pregnancy are necessary.

    The objective of this study is to answer the question: have we not been doing a lot of caesarean sections at University Teaching Hospital of Dakar? This is an analytic study about caesarean section in 1992, 1996 and 2001; it was a prospective and longitudinal data collection from the epidemiological survey program carried through in Senegal about its obstetrical and surgical cover. For each year concerned, we have analysed caesarean section rate, maternal mortality rate and perinatal mortality rate. To eliminate the random part in observed variation, we used the comparison of proportions observed as a statistical test with a significant threshold less or equal to 5%. Caesarean section has gone from 12% in 1992 to 17.5 in 1996 and 25.2% in 2001. Operative indications are dominated by foeto-pelvic disproportion with an average of 31% and foetal suffering with an average of 25%. The increasing trend has been statistically significant for information's such as foeto-pelvic disproportion and maternal pathologies. The falling trend was statistically significant for indications in relation on relation to foetal suffering and scarred uterus. Gathering information has shown a stabilisation of "obligatory" caesarean rate around 41%, a decrease in "caution" caesarean rate from 50 to 37.2% and an increase in caesarean by "necessity" from 8.6 to 22.4%. The maternal mortality rate among women delivered has fallen from 1.4% to 0.8%, but postoperative surgery morbidity rate was still high around 10%, essentially due to infections. Reading of caesarean section rate has not a significant impact in perinatal prognosis. Today there is an inflation of caesarean section at University Teaching Hospital of Dakar, without any significant loss of the maternal and perinatal mortality rate. The high level of complications due to surgery incite to reverse trends in order to get reasonable rate around 10 to 15% of childbirths.

  3. STUDY CONCERNING THE COSTS OF BIRTH BY CAESAREAN SECTION COMPARED TO NATURAL BIRTH

    Full Text Available The birth by caesarean section has become an expanding phenomenon in the recent years, natural births being more and more rare in Romania. The increasing incidence of these operations has been observed in the recent years, in the conditions of more effective fetal monitoring, modification of the malpractice law and increasing degree of information of the women. In Romania, depending on the hospital, the percentage of births by caesarean section ranges between 20-80%, even 90% (these latter percentage being valid especially in private clinics. The percentage of the operations is higher in big cities, and in Bucharest about 70% of the births are done by C-section. The World Health Organization recommends a maximum percentage surgical intervention of 10-15%. Fearing the labor pain, more and more women are choosing to bring their children into the world by Caesarean section. Also the number of doctors who claim that cesarean section is a better option is increasing. Both persons involved in the birth process have the responsibility of that decision - meaning both mother and doctor. The option of the mother is very important, but the recommendation of the doctor can make the difference. The decision is not only of the doctor, he just presents the information that the mother does not know, mother's wish being the most important. In this paper we conducted a study to determine the comparative costs of the vaginal births with those by Caesarean section. The retrospective study was conducted between 01.01.2015 - 31.12.2015, on 3607 births registered in the Obstetrics and Gynecology Clinics of Clinical Emergency County Hospital Oradea. Gemellary births were excluded from the study. We analyzed the comparative costs of a vaginal birth and of a birth by caesarean section in order to highlight the share of cesarean births compared to vaginal births.

    Objective The aim of this study was to assess the effect of ‘population group’ classification, as a specific instance of ‘racial’ categorization, on caesarean section rates in South Africa. Design Information on ‘population group’ classification (‘Black’, ‘Coloured’, ‘Indian’ or ‘White’, as defined under apartheid legislation) and place of delivery, together with basic obstetric, sociodemographic and perinatal data, were extracted from the birth notification forms of 5456 children who made up the birth cohort of the Birth to Ten longitudinal study. This cohort included all births that occurred to mothers resident in Soweto-Johannesburg during a 7-week period in 1990. Results After accounting for differences in maternal age, gravidity, birth weight and gestational age at delivery, the rate of caesarean sections at private facilities was more than twice that at public facilities. Although there were significant differences in the utilisation of private facilities by women from different ‘population groups’, there was an independent effect of ‘population group’ classification on caesarean section rates: caesarean section rates among women classified as ‘White’ and ‘Coloured’ were significantly higher (95% confidence intervals for odds ratios: 1.40-2.42 and 1.05-1.81, respectively) than among women classified as ‘Black’. Conclusion ‘Population group’ differences in caesarean section rates among South African women are not explained by differences in demographic risk factors for assisted delivery, nor by differences in access to private health care. Instead, the differences in section rates may reflect the effect of bias in clinical decision-making, and/or differences among women from different ‘population groups’ in their attitude towards assisted delivery, and their capacity to negotiate with clinicians.

    Objective: To determine the prediction rate of success in trial of labour after one previous caesarean section. Methods: The cross-sectional study was conducted at the Department of Obstetrics and Gynaecology, Cantonment General Hospital, Rawalpindi, from January 1, 2012 to January 31, 2013, and comprised women with one previous Caesarean section and with single alive foetus at 37-41 weeks of gestation. Women with more than one Caesarean section, unknown site of uterine scar, bony pelvic deformity, placenta previa, intra-uterine growth restriction, deep transverse arrest in previous labour and non-reassuring foetal status at the time of admission were excluded. Intrapartum risk assessment included Bishop score at admission, rate of cervical dilatation and scar tenderness. SPSS 21 was used for statistical analysis. Results: Out of a total of 95 women, the trial was successful in 68 (71.6%). Estimated foetal weight and number of prior vaginal deliveries had a high predictive value for successful trial of labour after Caesarean section. Estimated foetal weight had an odds ratio of 0.46 (p<0.001), while number of prior vaginal deliveries had an odds ratio of 0.85 with (p=0.010). Other factors found to be predictive of successful trial included Bishop score at the time of admission (p<0.037) and rate of cervical dilatation in the first stage of labour (p<0.021). Conclusion: History of prior vaginal deliveries, higher Bishop score at the time of admission, rapid rate of cervical dilatation and lower estimated foetal weight were predictive of a successful trial of labour after Caesarean section.

    Full Text Available Background and Aim: Recent developments in the field of intrathecal adjuvants have led to accelerated functional recovery with adequate postoperative analgesia following caesarean section. Encouraging results have been obtained with the use of intrathecal magnesium with or without fentanyl in parturients. This study was conceived to evaluate the effects of adding magnesium sulphate and/or fentanyl to low-dose intrathecal bupivacaine in parturients undergoing caesarean section under subarachnoid block (SAB. Materials and Methods: Ninety, American Society of Anesthesiologists I or II, parturients for the elective caesarean section were enrolled in this prospective randomized, double-blind study. The parturients were randomly assigned to three groups. In Group M, parturients received 8.5 mg (1.7 mL hyperbaric bupivacaine 0.5% with 50 mg (0.1 mL magnesium sulphate and 0.4 mL normal saline. Group F received 8.5 mg hyperbaric bupivacaine 0.5% with 20 μg (0.4 mL fentanyl and 0.1 mL of normal saline and Group MF parturients received 8.5 mg hyperbaric bupivacaine 0.5% with 20 μg fentanyl added to 50 mg magnesium sulphate. Results: Parturients in the group MF were pain free for longest period (273.70 ± 49.30 min as compared to group M (252.67 ± 40.76 min and group F (239.80 ± 38.45 mins [gp MF vs F and, gp M vs F (P = 0.00]. The total doses of rescue analgesics were least in group MF (2.43 ± 0.56 and maximum in group F (3.30 ± 0.63, with comparable neonatal outcomes in three groups. Conclusion: Our data supports synergistic action of intrathecal magnesium sulphate to fentanyl, and it is concluded that on addition of intrathecal magnesium sulphate and fentanyl to low-dose bupivacaine as adjuvant in subarachnoid block, results in prolonged duration of postoperative analgesia with lesser pain scores and lesser dose of rescue analgesia with better haemodynamic stability.

    Full Text Available Background: Different volumes of local anaesthetic are employed in transversus abdominis plane (TAP block to provide analgesia for lower abdominal surgeries. Our aim was to compare the efficacy of high versus low volume of bupivacaine TAP block in providing postoperative analgesia for caesarean sections. Settings and Design: Prospective, single-blind, randomized comparative study was performed during post-operative period. Materials and Methods: Sixty patients who had received spinal anaesthesia for caesarean section were randomly allocated to one of three groups: Group A received 20 ml of 0.25% bupivacaine, Group B received 30 ml of 0.166% bupivacaine on each side TAP block under ultrasound guidance, respectively, and Group C did not receive TAP block. Multi-modal analgesia comprising paracetamol, diclofenac and patient-controlled analgesia (PCA morphine was administered to all patients. The primary outcome measure in our study was 24-h post-operative morphine consumption through intravenous (IV PCA. Other secondary outcome measures were pain scores, nausea, sedation and patient satisfaction scores. Statistical Analysis: Statistical analysis done using analysis of variance, Fisher's Exact test and Kruskal–Wallis test. Results: Our primary outcome measure of 24-h cumulative PCA morphine consumption was 18.2 ± 6.5, 17.9 ± 8.6 and 19.4 ± 8.4 mg in groups A, B and C, respectively (P = 0.819. In the secondary outcome measures, 100% of study population in group A & B and 95% of group C had pain score of 0-3 on Numerical Rating Scale (P = 1.000 at 24 hr. 19, 15 and17 patients in group A, B and C, respectively, agreed and 1, 5 and 3 patients in group A, B and C, respectively, very strongly agreed with patient satisfaction survey for pain management (P = 0.265. Conclusion: TAP block as a part of multi-modal analgesia is debatable in the context of reducing the need of post-operative opioids. The present study was unequivocal in that two different

    The present study was conducted to evaluate the suitability of a repeated-dose liver micronucleus (LMN) assay in young adult rats as a collaborative study by the Mammalian mutagenicity study (MMS) group. All procedures were performed in accordance with the standard protocols of the MMS Group. Six-week-old male Crl:CD(SD) rats (5 animals/group) received oral doses of the hepatocarcinogen N-nitrosomorpholine (NMOR) at 0 (control), 5, 10, and 30mg/kg/day (10mL/kg) for 14 days. Control animals received vehicle (water). Hepatocytes were collected from the liver 24h after the last dose, and the number of micronucleated hepatocytes (MNHEPs) was determined by microscopy. The number of micronucleated immature erythrocytes (MNIMEs) in the femoral bone marrow was also determined. The liver was examined using histopathologic methods after formalin fixation. The results showed statistically significant and dose-dependent increases in the number of MNHEPs in the liver at doses of 10mg/kg and greater when compared with the vehicle control. However, no significant increase was noted in the number of MNIMEs in the bone marrow at doses of up to 30mg/kg. Histopathology of the liver revealed hypertrophy and single cell necrosis of hepatocytes at doses of 5mg/kg and above. These results showed that the induction of micronuclei by NMOR was detected by the repeated-dose LMN assay, but not by the repeated-dose bone marrow micronucleus assay. Copyright © 2014 Elsevier B.V.

    The incidence of pruritus after elective caesarean section under spinal anaesthesia with subarachnoid morphine may be 60-100%, and is a common cause of maternal dissatisfaction. Ondansetron has been shown to reduce pruritus but the effect is short-lived. The objective of this randomized double-blind trial was to evaluate the anti-pruritic efficacy of granisetron compared with ondansetron. Eighty ASA I or II women undergoing elective caesarean section received spinal anaesthesia with 0.5% hyperbaric bupivacaine 10 mg, fentanyl 25 microg and preservative-free morphine 150 microg. After delivery of the baby and clamping of the umbilical cord, they were randomised to receive granisetron 3mg i.v. (group G) or ondansetron 8 mg i.v. (group O). The two groups were similar for age, gestational age, height and weight. According to visual analogue pruritus scores, patients in group G experienced less pruritus at 8h (P=0.003) and 24h (P=0.01). Fewer patients in group G (n=8) than group O (n=18) required rescue anti-pruritic medication (P=0.03). Satisfaction scores were also higher in group G than in group O (P=0.03). There was no difference in overall incidence of pruritus, nausea and vomiting, and visual analogue pain scores between the two groups. Administration of granisetron 3mg i.v. reduces the severity of pruritus and the use of rescue anti-pruritic medication, and improves satisfaction but does not reduce the overall incidence of pruritus in women who have received subarachnoid morphine 150 microg compared to ondansetron 8 mg i.v.

METHODS: Eighty ASA I or II women undergoing elective caesarean section received spinal anaesthesia with 0.5% hyperbaric bupivacaine 10 mg, fentanyl 25 microg and preservative-free morphine 150 microg. After delivery of the baby and clamping of the umbilical cord, they were randomised to receive granisetron 3mg i.v. (group G) or ondansetron 8 mg i.v. (group O). RESULTS: The two groups were similar for age, gestational age, height and weight. According to visual analogue pruritus scores, patients in group G experienced less pruritus at 8h (P=0.003) and 24h (P=0.01). Fewer patients in group G (n=8) than group O (n=18) required rescue anti-pruritic medication (P=0.03). Satisfaction scores were also higher in group G than in group O (P=0.03). There was no difference in overall incidence of pruritus, nausea and vomiting, and visual analogue pain scores between the two groups. CONCLUSIONS: Administration of granisetron 3mg i.v. reduces the severity of pruritus and the use of rescue anti-pruritic medication, and improves satisfaction but does not reduce the overall incidence of pruritus in women who have received subarachnoid morphine 150 microg compared to ondansetron 8 mg i.v.

    This article aims at assessing the joint effect of maternal age and education on the risk of having a caesarean delivery. As high maternal education is often associated with lower caesarean-birth rates, but high-educated women tend to postpone motherhood, these effects may offset each other in traditional analyses. Secondary analysis of the data from the German Family Panel pairfam. The interview-based data refer to 1020 births between 2008 and 2015. We analyse only reports from mothers and calculate logistic regression models. The caesarean delivery rate differs strongly between education levels, and low-educated women are at higher risk of having a caesarean delivery when controlling for parity and age. A positive age gradient is found, indicating a higher risk of caesarean section for older mothers. Without controlling for age, the association of education and caesarean section risk is weaker, i.e., effects of age and education partially level each other out. A model including an interaction term between age and education confirms this result. The risk of having a caesarean delivery does not differ between levels of education when maternal age is not taken into account. Lower maternal education and higher age are both positively associated with the risk of experiencing a caesarean section in Germany. However, as higher educated women tend to have their children later, effects of education and age weigh each other out. Preventive campaigns should target women with lower education and raise women's awareness on the risks associated with late motherhood. Copyright © 2017 The Royal Society for Public Health.

    Full Text Available Purpose. To compare the incidence of nausea, vomiting, and arterial hypotension between carbetocin and oxytocin to prevent haemorrhage after caesarean section (CS. Methods. A randomized controlled trial in term pregnant women undergoing planned CS. Groups were randomized to carbetocin or oxytocin. Blood pressure (BP, heart rate, presence of nausea/vomitus, and need for vasopressors were evaluated throughout surgery. Preoperative and postoperative haemoglobin and haematocrit levels were compared. Results. Fifty-eight women were randomized (carbetocin n=32; oxytocin n=26. Both medications had hypotensive effect, difference in BP for carbetocin versus oxytocin: systolic (14.4 ± 2.4 mmHg versus 8.5 ± 1.8 mmHg; diastolic (7.8 ± 1.6 mmHg versus 8.9 ± 3.0 mmHg without significant difference between the drugs (p=0.1 and p=0.7. Both groups had similar needs for vasopressors. The presence of nausea was not rare, but the difference was not statistically significant (p=0.4. Average blood loss was slightly lower in the carbetocin group but not statistically significant (p=0.8. Conclusion. In planned CS, a possible clinical significant lower incidence of nausea after carbetocin was noted but this was not statistically significant. There were no differences regarding BP, heart rate, the need for vasopressor, and blood loss. The study was registered in the International Journal of Clinical Trials (ISRCTN 95504420, 2/2017.

    Vaginal birth after caesarean (VBAC) is an alternative option for women who have had a previous caesarean section (CS); however, uptake is limited because of concern about the risks of uterine rupture. The aim of this study was to explore women's decision-making processes and the influences on their mode of birth following a previous CS. A qualitative approach was used. The research comprised three stages. Stage I consisted of naturalistic observation at 33-34 weeks' gestation. Stage II involved interviews with pregnant women at 35-37 weeks' gestation. Stage III consisted of interviews with the same women who were interviewed postnatally, 1 month after birth. The research was conducted in a private medical centre in northern Taiwan. Using a purposive sampling, 21 women and 9 obstetricians were recruited. Data collection involved in-depth interviews, observation and field notes. Constant comparative analysis was employed for data analysis. Ensuring the safety of mother and baby was the focus of women's decisions. Women's decisions-making influences included previous birth experience, concern about the risks of vaginal birth, evaluation of mode of birth, current pregnancy situation, information resources and health insurance. In communicating with obstetricians, some women complied with obstetricians' recommendations for repeat caesarean section (RCS) without being informed of alternatives. Others used four step decision-making processes that included searching for information, listening to obstetricians' professional judgement, evaluating alternatives, and making a decision regarding mode of birth. After birth, women reflected on their decisions in three aspects: reflection on birth choices; reflection on factors influencing decisions; and reflection on outcomes of decisions. The health and wellbeing of mother and baby were the major concerns for women. In response to the decision-making influences, women's interactions with obstetricians regarding birth choices

    This retrospective study reviewed the mode of delivery when vaginal prostaglandins were used to induce labour in women with a single previous lower segment caesarean section. Over a 4-year period, PGE 2 gel was used cautiously in low doses in 54 women. Induction with PGE 2 gel was associated with an overall vaginal birth after caesarean section (VBAC) rate of 74%, which compared favourably with the 74% VBAC rate in women who went into spontaneous labour (n = 1969). There were no adverse outcomes recorded after the prostaglandin inductions but the number reported are too small to draw any conclusions about the risks, such as uterine rupture. We report our results because they may be helpful in assessing the chances of a successful VBAC in the uncommon clinical circumstances where prostaglandin induction is being considered.

    Full Text Available A 31-year-antenatal lady with critical mitral stenosis presented for emergency caesarean section with fetal distress. She had acute onset atrial fibrillation. She was given a combined spinal epidural (CSE anaesthesia and her arrhythmia was successfully managed after delivery of the baby with intravenous calcium channel blocker. Mitral stenosis is the most common valvular heart disease complicating pregnancy in developing countries. The physiological changes during pregnancy may exacerbate their cardiac symptoms. They may present with complications like congestive cardiac failure, atrial fibrillation, or pulmonary thromboembolism during the antenatal, intrapartum, or postpartum period. Here we discuss the management of parturient woman with high maternal and fetal risk presenting for emergency caesarean. The merits of regional anaesthesia and the importance of invasive monitoring are also discussed.

    Full Text Available This is a rare case of persistent Horner′s syndrome following epidural anesthesia and Caesarean section. A 33-year-old female presented with persistent ptosis and miosis following epidural anesthesia and Caesarian section several months prior. Magnetic resonance imaging (MRI/magnetic resonance angiography (MRA of head, neck, and chest were unremarkable. Medline search using terms Horner′s, epidural, spinal anesthesia, delivery, childbirth, Caesarian, and pregnancy identified 31 articles describing Horner′s syndrome in obstetric epidural anesthesia, of which 11 were following Caesarean section. The increased incidence of Horner′s syndrome in the setting of epidural anesthesia in pregnancy may be related to epidural venous engorgement and cephalic spread of the local anaesthetic, with disruption in the oculosympathetic pathway. It is important to include recent epidural anesthesia within the differential diagnosis of acute Horner′s syndrome in a postpartum female. Rarely, the ptosis may be permanent and require surgical intervention.

    Pregnancy is associated with both anatomical and physiological changes in the body, especially in cardiovascular and respiratory systems. Patients with anterior and middle mediastinal masses are recognized to be at risk for cardiorespiratory compromise. Likewise, pregnancy has a widely known constellation of potential complications that confront the anaesthesiologist. The combination of both (pregnancy and mediastinal mass) in a single patient presents an unusual anaesthetic challenge. Caesarean sections are usually the mode of delivery, therefore, the cardio-respiratory stability is very important. The following is the report of a 31 weeks pregnant patient with a large, symptomatic anterior and middle mediastinal mass, who required anaesthesia for emergency caesarean section. The anaesthetic management entailed Combined Spinal and Epidural (CSE) technique with safe feto-maternal outcome. (author)

  1. A Combination of Surgery And Methotrexate for Successful Treatment of a Caesarean Scar Ectopic Pregnancy.

    Tadesse, WG

    2018-06-01

    Caesarean scar ectopic pregnancy (CSEP) is one of the rarest forms of ectopic pregnancies. With rising caesarean delivery (CD) rates worldwide, there is an increase in the incidence of CSEP. Patients usually present with painless vaginal bleeding and often misdiagnosed as spontaneous miscarriage. The use of ultrasonography with colour flow Doppler helps in the differential diagnosis. Different treatment options are described in the literature, although there is insufficient evidence regarding the best approach. We report the diagnosis and management of a case of CSEP in a woman with four previous CD who presented with vaginal bleeding and lower abdominal cramps at six weeks of gestation. She was treated with laparoscopic and ultrasound guided aspiration of the gestational sac and local injection of methotrexate supplemented by intramuscular methotrexate injection.

    To compare the effectiveness of carbetocin and oxytocin when they are administered after caesarean section for prevention of postpartum haemorrhage (PPH). Double-blind randomised single centre study (1:1 ratio). Teaching hospital in Bristol, UK with 6000 deliveries per annum. Women at term undergoing elective or emergency caesarean section under regional anaesthesia, excluding women with placenta praevia, multiple gestation and placental abruption. Women were randomised to receive either carbetocin 100 microg or oxytocin 5 IU intravenously after the delivery of the baby. Perioperative care was otherwise normal and use of additional oxytocics was at the discretion of the operating obstetrician. Analysis was by intention to treat. The proportion of women in each arm of the trial that needed additional pharmacological oxytocic interventions. Significantly more women needed additional oxytocics in the oxytocin group (45.5% versus 33.5%, Relative risk 0.74, 95% CI 0.57-0.95). The majority of women had oxytocin infusions. There were no significant differences in the secondary outcomes, including major PPH, blood transfusions and fall in haemoglobin. Carbetocin is associated with a reduced use of additional oxytocics. It is unclear whether this may reduce rates of PPH and blood transfusions.

Based on the four data waves on the TEPS, we consider two abilities (general and mathematic and two population groups (male and female students to construct a multi-group multivariate linear growth model. Because the two-group multivariate repeated measures belong to the different populations and the different research variables, the residual terms of linear growth models may imply heterogeneity of the error covariance structure. We treat the error covariance structure as an unrestricted structure to compare the various types of models. The results from the HLM on the complete data (2,806 students reveal that the male and female students in this study have the same error covariance structure but have distinct linear growth trajectories. In addition, comparisons of the competitive models and related suggestions are discussed in the results and conclusion

  4. Revisiting the TALE repeat.

    Transcription activator-like (TAL) effectors specifically bind to double stranded (ds) DNA through a central domain of tandem repeats. Each TAL effector (TALE) repeat comprises 33-35 amino acids and recognizes one specific DNA base through a highly variable residue at a fixed position in the repeat. Structural studies have revealed the molecular basis of DNA recognition by TALE repeats. Examination of the overall structure reveals that the basic building block of TALE protein, namely a helical hairpin, is one-helix shifted from the previously defined TALE motif. Here we wish to suggest a structure-based re-demarcation of the TALE repeat which starts with the residues that bind to the DNA backbone phosphate and concludes with the base-recognition hyper-variable residue. This new numbering system is consistent with the α-solenoid superfamily to which TALE belongs, and reflects the structural integrity of TAL effectors. In addition, it confers integral number of TALE repeats that matches the number of bound DNA bases. We then present fifteen crystal structures of engineered dHax3 variants in complex with target DNA molecules, which elucidate the structural basis for the recognition of bases adenine (A) and guanine (G) by reported or uncharacterized TALE codes. Finally, we analyzed the sequence-structure correlation of the amino acid residues within a TALE repeat. The structural analyses reported here may advance the mechanistic understanding of TALE proteins and facilitate the design of TALEN with improved affinity and specificity.

    An extended reach EPON repeater is one of the solutions to effectively expand FTTH service areas. In this paper, we propose a reconfigurable multi-port EPON repeater for effective accommodation of multiple ODNs with a single OLT line card. The proposed repeater, which has multi-ports in both OLT and ODN sides, consists of TRs, BTRs with the CDR function and a reconfigurable electrical matrix switch, can accommodate multiple ODNs to a single OLT line card by controlling the connection of the matrix switch. Although conventional EPON repeaters require full OLT line cards to accommodate subscribers from the initial installation stage, the proposed repeater can dramatically reduce the number of required line cards especially when the number of subscribers is less than a half of the maximum registerable users per OLT. Numerical calculation results show that the extended reach EPON system with the proposed EPON repeater can save 17.5% of the initial installation cost compared with a conventional repeater, and can be less expensive than conventional systems up to the maximum subscribers especially when the percentage of ODNs in lightly-populated areas is higher.

    Full Text Available Background and Aims: Subarachnoid block is one of the common modes of anaesthesia opted for emergency caesarean section, if the maternal and foetal conditions are favourable. Various factors influence the quality of care administered during the procedure. This questionnaire based study was undertaken to look for self-expressed problems in peri-operative period in patients undergoing emergency caesarean surgery under subarachnoid block. Methods: All the parturients who underwent emergency caesarean section under subarachnoid block during 6 months period were distributed a questionnaire in post-operative period. They were encouraged to fill and return the form within 15 days. Patient satisfaction and the self-expressed problems were analysed at the end of 6 months. Results: One hundred and seventy five out of 220 parturients responded. 58.3% of them said that they were explained about the anaesthesia prior to surgery and 85.3% overall remained anxious. With people around them, 93.1% of them felt comfortable and 91.4% expressed that they were made comfortable inside the theatre. The self-expressed problems were shivering (43.4%, breathlessness (21.7%, pain (20%, post-operative headache (15.4% and backache (19.4%. Parturients who heard their babies cry was 85.1%. After their babies were shown after delivery, 77.1% mothers slept well; 86.9% fed their babies within 4 h of delivery. Conclusion: Pre-operative communication in emergency caesarean section by health personnel did not reduce the anxiety level, which shows that communication was ineffective. Intra-operative psychological support like making the patient comfortable, showing baby to mother and early breast feeding improve bonding between child and mother and essentially contribute to patient satisfaction.

    We present a scheme for playing quantum repeated 2 × 2 games based on Marinatto and Weber’s approach to quantum games. As a potential application, we study the twice repeated Prisoner’s Dilemma game. We show that results not available in the classical game can be obtained when the game is played in the quantum way. Before we present our idea, we comment on the previous scheme of playing quantum repeated games proposed by Iqbal and Toor. We point out the drawbacks that make their results unacceptable. (paper)

    2009-12-01

    Using data about births from the perinatal information system (PIS) registered in Montevideo (Uruguay), we estimated the probability of having a Caesarian section delivery, controlled by risk factors and the endogeneity of the choice of hospital. In public hospitals in Montevideo there is a fixed payment system, but in private hospitals this procedure has to be paid for separately. In the former, there is no effect on the doctor's income if he performs a Caesarian, but in the latter there is a positive effect. Empirical evidence shows the probability of a Caesarean section increases with the age of the woman, the presence of eclampsy, pre-eclampsy, previous hypertension, previous Caesarean sections, multiple pregnancies and fetopelvic disproportion, and decreases for multiparous women and women in a public hospital. In fact, the probability of having a Caesarean section in a private institution is almost two times higher than in a public hospital (20% as against 39%). Focusing on women without risk factors, we found that the probability a Caesarian in a public hospital was 11%, but the probability in a private hospital was 25%. We conclude that the remuneration system explains an important part of this difference.

    We investigated block heights that anaesthetists considered adequate for caesarean section to proceed under spinal anaesthesia. During 3 months, 15 obstetric anaesthetists recorded block height to touch, pinprick or cold when spinal anaesthesia was considered satisfactory for caesarean section to proceed. Median (IQR [range]) block height for touch, pinprick, first cold and icy were: T10 (T7-T12 [T3-L1]); T5 (T4-T6 [C7-L1]); T5 (T4-T6 [C7-L1]); and T3 (T2-T4 [C7-L1]), respectively. Modalities were significantly correlated for: touch and cold, p = 0.0001; touch and icy, p = 0.0007; touch and pinprick, p = 0.0018; cold and icy, p satisfactory anaesthesia despite 76 (81%) having a block to touch below T6. Single modality assessment of block height, particularly using touch, may erroneously indicate inadequate anaesthesia for caesarean section.

    The Free Deliveries and Caesarean Policy (FDCP) entitles all women in Morocco to deliver free of charge within public hospitals. This study assesses the policy's effectiveness by analysing household expenditures related to childbirth, by delivery type and quintile. Structured exit survey of 973 women in six provinces at five provincial hospitals, two regional hospitals, two university hospitals and three primary health centres with maternity units. Households reported spending a median of US$ 59 in total for costs inside and outside of hospitals. Women requiring caesareans payed more than women with uncomplicated deliveries (P < 0.0001). The median cost was US$45 for a uncomplicated delivery, US$50 for a complicated delivery and US$65 for a caesarean section. The prescription given upon exiting the hospital comprised 62% of the total costs. Eighty-eight per cent of women from the poorest quintiles faced catastrophic expenditures. The women's perception of their hospital stay and the FDCP policy was overwhelmingly positive, but differences were noted at the various sites. The policy has been largely but not fully effective in removing financial barriers for delivery care in Morocco. More progress should also be made on increasing awareness of the policy and on easing the financial burden, which is still borne by households with lower incomes. © 2015 John Wiley & Sons Ltd.

    2017-01-01

    Full Text Available Objective. To summarise the evidence for use of intravenous magnesium for analgesic effect in caesarean section patients. Background. Postcaesarean pain requires effective analgesia. Magnesium, an N-methyl-D-aspartate receptor antagonist and calcium-channel blocker, has previously been investigated for its analgesic properties. Methods. A systematic search was conducted of PubMed, Scopus, MEDLINE, Cochrane Library, and Google Scholar databases for randomised-control trials comparing intravenous magnesium to placebo with analgesic outcomes in caesarean patients. Results. Ten trials met inclusion criteria. Seven were qualitatively compared after exclusion of three for unclear bias risk. Four trials were conducted with general anaesthesia, while three utilised neuraxial anaesthesia. Five of seven trials resulted in decreased analgesic requirement postoperatively and four of seven resulted in lower serial visual analogue scale scores. Conclusions. Adjunct analgesic agents are utilised to improve analgesic outcomes and minimise opioid side effects. Preoperative intravenous magnesium may decrease total postcaesarean rescue analgesia consumption with few side effects; however, small sample size and heterogeneity of methodology in included trials restricts the ability to draw strong conclusions. Therefore, given the apparent safety and efficacy of magnesium, its role as an adjunct analgesic in caesarean section patients should be further investigated with the most current anaesthetic techniques.

    Globally 166 000 women die annually as a result of obstetric haemorrhage. More than 50% of these deaths occur in sub-Saharan Africa. Uterine atony is the commonest cause of severe postpartum haemorrhage (PPH). Bleeding at or after caesarean section (CS) is responsible for >30% of maternal deaths due to obstetric haemorrhage in South Africa (SA). To compare oxytocin alone with oxytocin + ergometrine in terms of primary prophylaxis for PPH at the time of CS. This was a double-blind randomised controlled interventional study comparing oxytocin with oxytocin + ergometrine administered during CS. Patients were randomised to receive oxytocin alone intravenously as a bolus or oxytocin + ergometrine intramuscularly, with the placebo being an injection of sterile water. The study population consisted of women undergoing CS at Kalafong Provincial Tertiary Hospital in Atteridgeville, Gauteng, SA. Five hundred and forty women were randomised and data for 416 women, of whom 214 received oxytocin and 202 oxytocin + ergometrine, were available for analysis. In the oxytocin group 19 women (8.9%) required blood transfusion, compared with seven (3.5%) in the oxytocin + ergometrine group (p=0.01; relative risk = 2.78; 95% confidence interval 1.21 - 6.4). There were no statistically significant differences in the mean estimated visual and mean calculated blood loss. The overall need for blood transfusion was significantly reduced by about two-thirds in women receiving the oxytocin + ergometrine combination. Consideration should be given to using oxytocin + ergometrine for prophylaxis of PPH at CS.

    2009-01-01

    We review the medical literature on the success, safety and economic value of central neuraxial blockade-assisted (CNB) external cephalic version from randomized controlled studies identified from 1951 to 2009. The result showed that more women had successful ECV with regional anaesthesia with corresponding reduction in caesarean section rate. They were 1.5 times more likely than women not receiving anaesthesia to have a successful ECV. The number to treat is six women needed to receive anaesthesia for 1 baby to be turned from breech to cephalic presentation. Feto-maternal morbidity was not increased in the CNB-aided group consisting of only transient bradycardia. Although the appropriate amount of force for safe version has not been quantified, there was no report of uterine rupture despite removal of these patients from “excessive force-pain biofeedback loop” induced through motor nerve blockade. We can attribute 30% of cost savings amounting to £42,150.00 directly to CNB using the most up to date Health Resource Group Code (HRG4). The initial results are encouraging but until the benefits and safety of CNB-aided ECV are substantiated by large randomized, blinded controlled trials, this practice cannot be universally recommended.

    Full Text Available We review the medical literature on the success, safety and economic value of central neuraxial blockade-assisted (CNB external cephalic version from randomized controlled studies identified from 1951 to 2009. The result showed that more women had successful ECV with regional anaesthesia with corresponding reduction in caesarean section rate. They were 1.5 times more likely than women not receiving anaesthesia to have a successful ECV. The number to treat is six women needed to receive anaesthesia for 1 baby to be turned from breech to cephalic presentation. Feto-maternal morbidity was not increased in the CNB-aided group consisting of only transient bradycardia. Although the appropriate amount of force for safe version has not been quantified, there was no report of uterine rupture despite removal of these patients from “excessive force-pain biofeedback loop” induced through motor nerve blockade. We can attribute 30% of cost savings amounting to £42,150.00 directly to CNB using the most up to date Health Resource Group Code (HRG4. The initial results are encouraging but until the benefits and safety of CNB-aided ECV are substantiated by large randomized, blinded controlled trials, this practice cannot be universally recommended.

    Bupivacaine is the most commonly used local anaesthetic for spinal anaesthesia (SA). There are two forms of commercially available bupivacaine; isobaric bupivacaine (IB): a formulation with a specific gravity or density equal to cerebrospinal fluid, and hyperbaric bupivacaine (HB): a formulation with density heavier than cerebrospinal fluid. The difference in densities of the two available preparations is believed to affect the diffusion pattern that determines the effectiveness, spread and side-effect profile of bupivacaine. This systematic review will summarise the best available evidence regarding the effectiveness and safety on the use of HB compared with IB, when used to provide SA for surgery. Primarily, we will analyse the need for conversion to general anaesthesia. As secondary outcomes, we will compare the incidence of hypotension, incidence of nausea/vomiting, the onset time and duration of anaesthesia. We will search key electronic databases using search strategy (1) injections, spinal OR intrathecal OR subarachnoid; (2) bupivacaine OR levobupivacaine; (3) hypobaric OR isobaric OR plain; (4) baricity. We will search MEDLINE, EMBASE and Cochrane databases, from their inception for randomised controlled trials, with no restrictions on language. Caesarean section surgery will be excluded. 2 reviewers will independently extract the data using a standardised form. Extracted items will include study characteristics, risk of bias domains, as per modified Cochrane risk of bias, participant disposition and study outcomes. We will conduct a meta-analysis for variables that can be compared across the studies. We will evaluate clinical heterogeneity by qualitatively appraising differences in study characteristics in participants, interventions and the outcomes assessed. We will report our findings as relative risks (dichotomous), and weighted mean differences (continuous) for individual outcomes, along with their 95% CIs. We plan to submit, and will publish, our

    This article investigates the determinants of repeat migration among the 44 regions of Canada, using information from a large micro-database which spans the period 1968 to 1971. The explanation of repeat migration probabilities is a difficult task, and this attempt is only partly successful. May of the explanatory variables are not significant, and the overall explanatory power of the equations is not high. In the area of personal characteristics, the variables related to age, sex, and marital status are generally significant and with expected signs. The distance variable has a strongly positive effect on onward move probabilities. Variables related to prior migration experience have an important impact that differs between return and onward probabilities. In particular, the occurrence of prior moves has a striking effect on the probability of onward migration. The variable representing disappointment, or relative success of the initial move, plays a significant role in explaining repeat migration probabilities. The disappointment variable represents the ratio of actural versus expected wage income in the year after the initial move, and its effect on both repeat migration probabilities is always negative and almost always highly significant. The repeat probabilities diminish after a year's stay in the destination region, but disappointment in the most recent year still has a bearing on the delayed repeat probabilities. While the quantitative impact of the disappointment variable is not large, it is difficult to draw comparisons since similar estimates are not available elsewhere.

    Full Text Available Background: Caesarean section is one of the most frequently performed surgeries in obstetrics. Optimal pain relief of the mother is possible with multimodal methods. Wound infiltration is one of the simplest and safe methods. The aim of the study was to compare the analgesic efficacy of wound infiltration of bupivacaine, with tramadol and bupivacaine mixture for postoperative pain. Materials and Methods: After obtaining Institutional Ethical Committee approval, 60 pregnant women of age group 18–35 years, undergoing elective caesarean section under spinal anaesthesia were included in the study. The patients were randomized into two groups of 30 each. Patients belonging to group B received bupivacaine 0.25% 0.7 mg/kg (diluted to 20 mL with normal saline, while those belonging to group T received tramadol 2 mg/kg mixed in bupivacaine 0.25% 0.7 mg/kg (diluted to 20 mL with normal saline. The time for first request of analgesia, numerical rating scale score, and cumulative consumption of diclofenac and tramadol in 24 h were compared. Results: The time for first request of analgesia in group T was 386.17 ± 233.84 min compared to group B which was 192.50 ± 134.77 (P < 0.0002. The total diclofenac consumption in the first 24 h was significantly reduced in group T when compared to group B (P < 0.0068. Conclusions: Subcutaneous wound infiltration with tramadol and bupivacaine prolongs the pain-free period and analgesic consumption after caesarean section, while it also enhances the patient satisfaction.

    The repeated-dose liver micronucleus (RDLMN) assay using young adult rats has the potential to detect hepatocarcinogens. We conducted a collaborative study to assess the performance of this assay and to evaluate the possibility of integrating it into general toxicological studies. Twenty-four testing laboratories belonging to the Mammalian Mutagenicity Study Group, a subgroup of the Japanese Environmental Mutagen Society, participated in this trial. Twenty-two model chemicals, including some hepatocarcinogens, were tested in 14- and/or 28-day RDLMN assays. As a result, 14 out of the 16 hepatocarcinogens were positive, including 9 genotoxic hepatocarcinogens, which were reported negative in the bone marrow/peripheral blood micronucleus (MN) assay by a single treatment. These outcomes show the high sensitivity of the RDLMN assay to hepatocarcinogens. Regarding the specificity, 4 out of the 6 non-liver targeted genotoxic carcinogens gave negative responses. This shows the high organ specificity of the RDLMN assay. In addition to the RDLMN assay, we simultaneously conducted gastrointestinal tract MN assays using 6 of the above carcinogens as an optional trial of the collaborative study. The MN assay using the glandular stomach, which is the first contact site of the test chemical when administered by oral gavage, was able to detect chromosomal aberrations with 3 test chemicals including a stomach-targeted carcinogen. The treatment regime was the 14- and/or 28-day repeated-dose, and the regime is sufficiently promising to incorporate these methods into repeated-dose toxicological studies. The outcomes of our collaborative study indicated that the new techniques to detect chromosomal aberrations in vivo in several tissues worked successfully. Copyright © 2015 The Authors.

    Full Text Available OBJECTIVE: To compare the risk of stillbirth and miscarriage in a subsequent pregnancy in women with a previous caesarean or vaginal delivery. DESIGN: Systematic review of the published literature including seven databases: CINAHL; the Cochrane library; Embase; Medline; PubMed; SCOPUS and Web of Knowledge from 1945 until November 11(th 2011, using a detailed search-strategy and cross-checking of reference lists. STUDY SELECTION: Cohort, case-control and cross-sectional studies examining the association between previous caesarean section and subsequent stillbirth or miscarriage risk. Two assessors screened titles to identify eligible studies, using a standardised data abstraction form and assessed study quality. DATA SYNTHESIS: 11 articles were included for stillbirth, totalling 1,961,829 pregnancies and 7,308 events. Eight eligible articles were included for miscarriage, totalling 147,017 pregnancies and 12,682 events. Pooled estimates across the stillbirth studies were obtained using random-effect models. Among women with a previous caesarean an increase in odds of 1.23 [95% CI 1.08, 1.40] for stillbirth was yielded. Subgroup analyses including unexplained stillbirths yielded an OR of 1.47 [95% CI 1.20, 1.80], an OR of 2.11 [95% CI 1.16, 3.84] for explained stillbirths and an OR of 1.27 [95% CI 0.95, 1.70] for antepartum stillbirths. Only one study reported adjusted estimates in the miscarriage review, therefore results are presented individually. CONCLUSIONS: Given the recent revision of the National Institute for Health and Clinical Excellence guidelines (NICE, providing women the right to request a caesarean, it is essential to establish whether mode of delivery has an association with subsequent risk of stillbirth or miscarriage. Overall, compared to vaginal delivery, the pooled estimates suggest that caesarean delivery may increase the risk of stillbirth by 23%. Results for the miscarriage review were inconsistent and lack of adjustment

    The aim of this study was to evaluate the effectiveness of three knowledge-transfer intervention trial types (postal, group, one-to-one) to promote best practice to treat sheep with footrot. Further aims were to investigate whether farmer behaviour (i.e. management of lameness) before the trial was associated with uptake of best practice and whether the benefits of best practice framed positively or negatively influenced change in behaviour. The intervention was a message developed from evidence and expert opinion. It was entitled "Six steps to sound sheep" and promoted (1) catch sheep within three days of becoming lame, (2) inspect feet without foot trimming, (3) correctly diagnose the cause, (4) treat sheep lame with footrot or interdigital dermatitis with antibiotic injection and spray without foot trimming, (5) record the identity of treated sheep, (6) cull repeatedly lame sheep. In 2013, 4000 randomly-selected English sheep farmers were sent a questionnaire, those who responded were recruited to the postal (1081 farmers) or one-to-one intervention (32 farmers) trials. A random sample of 400 farmers were invited to join the group trial; 78 farmers participated. A follow-up questionnaire was sent to all participants in summer 2014. There were 72%, 65% and 91% useable responses for the postal, group and one-to-one trials respectively. In both 2013 and 2014, the prevalence of lameness was lower in flocks managed by LC1 farmers than LC2 and LC3 farmers. Between 2013 and 2014, the reduction in geometric mean (95% CI) period prevalence of lameness, proportional between flock reduction in lameness and within flock reduction in lameness was greatest in the one-to-one (7.6% (7.1-8.2%) to 4.3% (3.6-5.0%), 35%, 72%) followed by the group (4.5% (3.9-5.0%) to 3.1% (2.4-3.7%), 27%, 55%) and then the postal trial (from 3.5% (3.3-3.7%) to 3.2% (3.1-3.4%), 21%, 43%). There was a marginally greater reduction in lameness in farmers using most of Six steps but slow to treat lame

    the attitudes of two counsellors towards women requesting a caesarean section due to fear of birth were identified. One emphasised the ability to overcome any emotional obstacle to vaginal birth ('coping attitude'), and the other emphasised that the ultimate choice of mode of birth was the womans' ('autonomy attitude'). Two research questions were asked: (1) What are the predictors of change in a wish for a caesarean and of vaginal birth in women with fear of birth? (2) Does a change from an 'autonomy attitude' to a 'coping attitude' increase the number of women who change their request for a caesarean and who give birth vaginally? the study population consisted of two samples of pregnant women with fear of birth and concurrent request for a caesarean, referred for crisis-oriented counselling at the antenatal clinic, University Hospital of North Norway between 2000-2002 (n=86) and 2004-2006 (n=107). Data were gathered from referral letters, counseling and antenatal, intra- and postpartum records. a coping attitude of the counsellor was positively associated with change in the request for a caesarean and with vaginal birth. A change from an autonomy attitude to a coping attitude was associated with a significant increase in the percentage of women who changed their desire for a caesarean from 77 to 93, and who had a vaginal birth from 42 to 81. a coping attitude was strongly associated with change in the desire for a caesarean and giving birth vaginally. A coping attitude can be learned through critical reflection and awareness of the counsellor's attitude, with measurable clinical results. Copyright 2008 Elsevier Ltd. All rights reserved.

    Hypotension necessitating vasopressor administration occurs commonly during caesarean section under spinal anaesthesia. We developed a novel vasopressor delivery system that automatically administers phenylephrine or ephedrine based on continuous non-invasive arterial pressure monitoring. A phenylephrine bolus of 50 μg was given at 30-s intervals when systolic blood pressure fell manual boluses of either phenylephrine 100 μg or ephedrine 8 mg, administered at 1-min intervals based on the same thresholds for systolic pressure and heart rate. This randomised, controlled, double-blinded trial involved 213 healthy women who underwent elective caesarean delivery under spinal anaesthesia using 11 mg hyperbaric bupivacaine with 15 μg fentanyl and 100 μg morphine. The automated vasopressor group had better systolic pressure control, with 37/106 (34.9%) having any beat-to-beat systolic pressure reading 120% of baseline, with 8/106 (7.5%) in the automated vasopressor group vs 14/107 (13.1%) in the control group, or total dose of vasopressors. The automated vasopressor group had lower median absolute performance error of 8.5% vs control of 9.8% (p = 0.013), and reduced incidence of nausea (1/106 (0.9%) vs 11/107 (10.3%), p = 0.005). Neonatal umbilical cord pH, umbilical lactate and Apgar scores were similar. Hence, our system afforded better control of maternal blood pressure and reduced nausea with no increase in reactive hypertension when compared with manual boluses. © 2013 The Association of Anaesthetists of Great Britain and Ireland.

    The optimal local-anaesthetic (LA) dose for transversus-abdominis-plane (TAP) block is unclear. In this meta-analysis, we aimed to determine whether TAP blocks for Caesarean delivery (CD) with low-dose (LD) LA demonstrated non-inferiority in terms of analgesic efficacy, compared with high-dose (HD) LA. A literature search was performed for randomised controlled trials examining the analgesic efficacy of TAP blocks vs control after CD. The different dosing used in these studies was classified as HD or LD (bupivacaine equivalents >50 or ≤50 mg per block side, respectively). The pooled results of each dose group vs control were indirectly compared using the Q test. The primary outcome was 24 h opioid consumption. Secondary outcomes included 6 and 24 h postoperative pain scores, time to first analgesia, 6 h opioid consumption, opioid-related side-effects, and maternal satisfaction. Fourteen studies consisting of 770 women (389 TAP and 381 control) were included. Compared with controls, the 24 h opioid consumption (milligram morphine equivalents) was lower in HD [mean difference (MD) 95% confidence interval (CI) -22.41 (-38.56, -6.26); P=0.007; I 2 =93%] and LD [MD 95% CI -16.29 (-29.74, -2.84); P=0.02; I 2 =98%] TAP groups. However, no differences were demonstrated between the HD and LD groups (P=0.57). There were also no differences between the HD and LD groups for the 6 h opioid consumption, time to first analgesia, 6 and 24 h pain scores, postoperative nausea and vomiting, pruritus, and maternal satisfaction. Low-dose TAP blocks for Caesarean delivery provide analgesia and opioid-sparing effects comparable with the high-dose blocks. This suggests that lower doses can be used to reduce local anaesthetic toxicity risk without compromising the analgesic efficacy. Copyright © 2017 British Journal of Anaesthesia.

    Does a primary Caesarean section influence the rate of, and time to, subsequent live birth compared with vaginal delivery? Caesarean section was associated with a reduction in the rate of subsequent live birth, particularly among elective and maternal-requested Caesareans indicating maternal choice plays a role. Several studies have examined the relationship between Caesarean section and subsequent birth rate with conflicting results primarily due to poor epidemiological methods. This Danish population register-based cohort study covered the period from 1982 to 2010 (N = 832 996). All women with index live births were followed until their subsequent live birth or censored (maternal death, emigration or study end) using Cox regression models. In all 577 830 (69%) women had a subsequent live birth. Women with any type of Caesarean had a reduced rate of subsequent live birth (hazard ratio [HR] 0.86, 95% confidence intervals [CI] 0.85, 0.87) compared with spontaneous vaginal delivery. This effect was consistent when analyses were stratified by type of Caesarean: emergency (HR 0.87, 95% CI 0.86, 0.88), elective (HR 0.83, 95% CI 0.82, 0.84) and maternal-requested (HR 0.61, 95% CI 0.57, 0.66) and in the extensive sub-analyses performed. Lack of biological data to measure a woman's fertility is a major limitation of the current study. Unmeasured confounding and limited availability of data (maternal BMI, smoking, access to fertility services and maternal-requested Caesarean section) as well as changes in maternity care over time may also influence the findings. This is the largest study to date and shows that Caesarean section is most likely not causally related to a reduction in fertility. Maternal choice to delay or avoid childbirth is the most plausible explanation. Our findings are generalizable to other middle- to high-income countries; however, cross country variations in Caesarean section rates and social or cultural differences are acknowledged.

    The incidence of caesarean section for breech presentation has increased markedly in the last 20 years. A prospective, interventional cohort study was carried out of the success rate of external cephalic version (ECV) and its predictors of as well as its impact on the rate of caesarean section for vaginal breech delivery. All 128 women admitted during the study period to the obstetrics department of a tertiary care military hospital in Taif, Saudi Arabia with breech presentation at term, regardless of age and parity, who accepted ECV were recruited. ECV was successful in 53.9% of the women. Most of the women with successful ECV delivered normally (84.1%) and only 14.5% of them delivered by caesarean section. Conversely, normal vaginal delivery was reported among 8.5% of those who had spontaneous version with failed ECV and approximately two-thirds of them delivered by caesarean section (62.7%). Successful ECV reduced the breech and caesarean section rate.

    The rate of caesarean section deliveries has increased globally and mothers are faced with challenges of postoperative recovery and caring thereof. Midwives have a duty to assist these mothers to self-care. The objective was to explore and describe experiences of post-caesarean section delivered mothers of midwifery care at a public hospital in Nelson Mandela Bay. A qualitative, descriptive and explorative research design was used in the study. Data were collected from 11 purposively criterion-selected mothers who had a caesarean section delivery. One-on-one semi-structured interviews were conducted in the post-natal wards. Research ethics, namely autonomy, beneficence, justice and informed consent, were adopted in the study. All participants were informed of their right to withdraw from the study at any stage without penalties. Interviews were analysed using Tesch's method of data analysis. Three main themes were identified as experiences of: diverse pain, physical limitation and frustration and health care services as different. Experiences of mothers following a caesarean section delivery with midwifery services at a public hospital in Nelson Mandela Bay were explored and described as diverse. A need for adequate pain management as well as assistance and breastfeeding support to mothers following caesarean delivery was identified as crucial to promote a good mother-to-child relationship.

    Abstract Among teleost fishes, Asian swamp eel (Monopterus albus Zuiew, 1793) possesses the lowest chromosome number, 2n = 24. To characterize the chromosome constitution and investigate the genome organization of repetitive sequences in M. albus, karyotyping and chromosome mapping were performed with the 18S – 28S rRNA gene, telomeric repeats, microsatellite repeat motifs, and Rex retroelements. The 18S – 28S rRNA genes were observed to the pericentromeric region of chromosome 4 at the same position with large propidium iodide and C-positive bands, suggesting that the molecular structure of the pericentromeric regions of chromosome 4 has evolved in a concerted manner with amplification of the 18S – 28S rRNA genes. (TTAGGG)n sequences were found at the telomeric ends of all chromosomes. Eight of 19 microsatellite repeat motifs were dispersedly mapped on different chromosomes suggesting the independent amplification of microsatellite repeat motifs in M. albus. Monopterus albus Rex1 (MALRex1) was observed at interstitial sites of all chromosomes and in the pericentromeric regions of most chromosomes whereas MALRex3 was scattered and localized to all chromosomes and MALRex6 to several chromosomes. This suggests that these retroelements were independently amplified or lost in M. albus. Among MALRexs (MALRex1, MALRex3, and MALRex6), MALRex6 showed higher interspecific sequence divergences from other teleost species in comparison. This suggests that the divergence of Rex6 sequences of M. albus might have occurred a relatively long time ago. PMID:29093797

  12. Elective caesarean section versus vaginal delivery. Whither the end of traditional obstetrics?

    Science.gov (United States)

    Husslein, P

    2001-11-01

    No other topic has dominated the obstetrical discussion to the same extent as caesarean section. Nor has any other aspect of obstetrics been subject to a comparable degree of professional controversy,quite recently the topic has been discussed in this journal by Ludwig and Loeffler. For some caesarean section remains a major surgical procedure with a corresponding level of risk, which must only be employed in the presence of specific complications and in conjunction with a clearly defined set of indications; others consider caesarean section quite simply to be the most efficient and straightforward means to deliver as well as the one attended by the least amount of risk. Opinion among those most immediately affected is likewise divided: For many women the experience of vaginal birth is among the most fulfilling of their entire life - comparable only to sexuality-related moments of ecstasy - other women come to regard birth as the worst thing that ever happened to them an experience attended by pain, fear, loneliness, perhaps even long lasting negative consequences. There can be no doubt that, this question also affects the foundations of patriarchal thinking, still so firmly embedded in peoples' minds: Are doctors to determine what exactly takes place in the delivery room and in the operating theatre, or will the patient - in obstetrics, the parturient - be enabled to assert her right to self-determination also in the medical context; especially in light of the fact that said right can currently be exercised in an almost unlimited fashion throughout the rest of one's adult life? It is against the wider background of this ongoing controversy that the ensuing article will seek to defuse the emotional charge characterising some of the commonly employed arguments and instead revert to a more rational and factually based approach to this question.

  13. Successful use of sugammadex for caesarean section in a patient with myasthenia gravis

    Directory of Open Access Journals (Sweden)

    Lokman Soyoral

    Full Text Available Abstract Myasthenia gravis is an autoimmune disorder that is characterized by muscle weakness that fluctuates, worsening with exertion, and improving with rest. Diagnosis of myasthenia gravis is made following clinical and physical examination and is confirmed by serum immunoassays to measure autoantibody levels. Myasthenia gravis especially when associated with pregnancy is a high-risk disease, and its course is unpredictable. We described the second report about use of sugammadex after rocuronium for a caesarean delivery with myasthenia gravis, but, unlike our case that formerly was diagnosed with myasthenia gravis, the patient was extubated on postoperative successfully and we did not encounter any respiratory problems.

    2007-10-01

    We describe a 30-year-old parturient with acute generalised pustular psoriasis who presented for urgent caesarean section. A multidisciplinary team was involved and general anaesthesia was used successfully. Management of this condition is discussed and the literature reviewed. While generalised pustular psoriasis or impetigo herpetiformis is well recognised in pregnancy, it has not hitherto been reported in obstetric anaesthesia literature. The purpose of this article is to delineate the clinical picture of this disease, its treatment, and the effect on the mother and the fetus.

    Full Text Available Successful anaesthetic management for caesarean section in a case with previous pituitary tumour resection, with residual tumour, is reported. The pituitary gland undergoes global hyperplasia during pregnancy. Functional pituitary tumours may exhibit symptomatic enlargement during pregnancy. Growth hormone secreting tumour is associated with acromegaly which has associated anaesthetic implications of difficult airway, systemic hypertension, and diabetes and electrolyte imbalance. Intracranial space occupying lesions can increase intra cranial pressure and compromise cerebral perfusion or cause herniation. We report management of this case.

    Full Text Available Phaeochromocytoma is a rare cause of hypertension during pregnancy with potentially fatal consequences. If not detected and treated early in pregnancy, it is catastrophic for both the mother and the baby. Management requires close co-ordination between the obstetrician, anaesthesiologist, paediatrician and the endocrinologist. Perioperative management for an emergency caesarean section in a parturient with untreated phaeochromocytoma is an anaesthetic challenge and no standard recommendations have been reported till date. In this case report, we present anaesthetic management in such a case with successful maternal and foetal outcome.

    2014-04-01

    Full Text Available At Pravara Rural Hospital a 29 year old patient was admitted for delivery. Patient had conjoint-twins diagnosed after sonography and was posted for elective caesarean section. Patient was managed under general anaesthesia after thorough preparation and under multi-disciplinary involvement. Both the twins females were living and were further managed by neonatologists. Though conjoint-twins are rare and patients coming for delivery with conjoint-twins are still rarer because of early diagnosis and termination, anaesthesiologists working in developing countries and working in remote areas may face such patients. There are very few publications for management of delivery in such patients, hence this case report.

    Caesarean section (CS) is often a life-saving procedure, but can also lead to serious complications, even more so in low-resource settings. Therefore unnecessary CS should be avoided and optimal circumstances for vaginal delivery should be created. In this study, we aim to audit indications for Caesarean sections and improve decision-making and obstetric management. Audit of all cases of CS performed from January to August 2013 was performed in a rural referral hospital in Tanzania. The study period was divided in three audit blocks; retrospective (before auditing), prospective 1 and prospective 2. A local audit panel (LP) and an external auditor (EA) judged if obstetric management was adequate and indications were appropriate or if CS could have been prevented and yet retain good pregnancy outcome. Furthermore, changes in modes of deliveries, overall pregnancy outcome and decision-to-delivery interval were monitored. During the study period there were 1868 deliveries. Of these, 403 (21.6%) were Caesarean sections. The proportions of unjustified CS prior to introduction of audit were as high as 34 and 75%, according to the respective judgments of LP and EA. Following introduction of audit, the proportions of unjustified CS decreased to 23% (p = 0.29) and 52% (p = 0.01) according to LP and EA respectively. However, CS rate did not change (20.2 to 21.7%), assisted vacuum delivery rate did not increase (3.9 to 1.8%) and median decision-to-delivery interval was 83 min (range 10 - 390 min). Although this is a single center study, these findings suggest that unnecessary Caesarean sections exist at an alarming rate even in referral hospitals and suggest that a vast number can be averted by introducing a focused CS audit system. Our findings indicate that CS audit is a useful tool and, if well implemented, can enhance rational use of resources, improve decision-making and harmonise practice among care providers.

    Several studies have shown differences in the composition of the gastrointestinal flora of children who develop sensitization to food allergens compared with non-allergic children. It has been hypothesized that changes in the gut microbiota resulting from caesarean section delivery could increase a child's risk of developing food allergy; however, studies examining the relationship between mode of delivery and food allergy have produced conflicting results. The objective of this review was to determine whether there is sufficient evidence to support an association between delivery by caesarean section and the development of sensitization to food allergens and immunoglobulin E (IgE) mediated food allergy. Using predefined inclusion and exclusion criteria, MEDLINE and PubMed were searched for studies investigating the relationship between caesarean section delivery and food allergy. The information on the quality of the studies and results were extracted and analysed systematically. The search identified four relevant studies as per our protocol. Symptomatic food allergy was used as the outcome in two studies and was found to occur more frequently in children born by caesarean section in one study while the second study found no association between food allergy diagnoses and mode of delivery. The other two studies measured levels of food antigen-specific IgE, with both studies showing an increase in sensitization to food allergens among children born by caesarean section. Overall, there is evidence that the risk of developing IgE-mediated sensitization to food allergens is increased among children delivered by caesarean section, however further studies using objectively diagnosed food allergy as the outcome are needed to verify whether this equates to an increase in confirmed food allergy. Future birth cohort studies should control for the effects of mode of delivery when investigating environmental modifiers of food allergy.

    Objective To assess the differences in rates and odds for emergency caesarean section among singleton pregnancies in six governmental Palestinian hospitals. Design A prospective population-based birth cohort study. Setting Obstetric departments in six governmental Palestinian hospitals. Participants 32 321 women scheduled to deliver vaginally from 1 March 2015 until 29 February 2016. Methods To assess differences in sociodemographic and antenatal obstetric characteristics by hospital, χ2 test, analysis of variance and Kruskal-Wallis test were applied. Logistic regression was used to estimate differences in odds for emergency caesarean section, and ORs with 95% CIs were assessed. Main outcome measures The primary outcome was the adjusted ORs of emergency caesarean section among singleton pregnancies for five Palestinian hospitals as compared with the reference (Hospital 1). Results The prevalence of emergency caesarean section varied across hospitals, ranging from 5.8% to 22.6% among primiparous women and between 4.8% and 13.1% among parous women. Compared with the reference hospital, the ORs for emergency caesarean section were increased in all other hospitals, crude ORs ranging from 1.95 (95% CI 1.42 to 2.67) to 4.75 (95% CI 3.49 to 6.46) among primiparous women. For parous women, these differences were less pronounced, crude ORs ranging from 1.37 (95% CI 1.13 to 1.67) to 2.99 (95% CI 2.44 to 3.65). After adjustment for potential confounders, the ORs were reduced but still statistically significant, except for one hospital among parous women. Conclusion Substantial differences in odds for emergency caesarean section between the six Palestinian governmental hospitals were observed. These could not be explained by the studied sociodemographic or antenatal obstetric characteristics. PMID:29500211

    To investigate the association between maternal country of birth and father's origin and unplanned and planned caesarean birth in Sweden. Population-based register study including all singleton births in Sweden between 1999 and 2012 (n = 1 311 885). Multinomial regression was conducted to estimate odds ratios (OR) for unplanned and planned caesarean with 95% confidence intervals for migrant compared with Swedish-born women. Analyses were stratified by parity. Women from Ethiopia, India, South Korea, Chile, Thailand, Iran, and Finland had statistically significantly higher odds of experiencing unplanned (primiparous OR 1.10-2.19; multiparous OR 1.13-2.02) and planned caesarean (primiparous OR 1.18-2.25; multiparous OR 1.13-2.46). Only women from Syria, the former Yugoslavia and Germany had consistently lower risk than Swedish-born mothers (unplanned: primiparous OR 0.76-0.86; multiparous OR 0.74-0.86. Planned; primiparous OR 0.75-0.82; multiparous OR 0.60-0.94). Women from Iraq and Turkey had higher odds of an unplanned caesarean but lower odds of a planned one (among multiparous). In most cases, these results remained after adjustment for available social characteristics, maternal health factors, and pregnancy complications. Both parents being foreign-born increased the odds of unplanned and planned caesarean in primiparous and multiparous women. Unplanned and planned caesarean birth varied by women's country of birth, with both higher and lower rates compared with Swedish-born women, and the father's origin was also of importance. These variations were not explained by a wide range of social, health, or pregnancy factors. © 2017 John Wiley & Sons Ltd.

    This qualitative research focused on the significance of subjective experience of mothers who gave birth in an emergency Caesarean section. Ten first-time mothers experiencing emergency Caesarean section were interviewed, and their narrative accounts were analyzed using Giorgi's phenomenological method. Mothers described alienation from the infant on encountering her/him; primal difficulties in holding; a 'mechanistic' pattern of childcare at home; over-apprehension and fear of a cradle-death. A few of the women seemed to cope with these experiences by performing 'a symbolic adoption' of their infants. In the context of object-relations theory, the findings, will potentially inform psychological care in obstetrics and gynaecology.

    The objective of this study was to assess effectiveness and safety of the reverse breech extraction approach in Caesarean section for obstructed labour, and compare it with the standard approach of pushing the fetal head up through the vagina. This randomised controlled trial included 192 women. In 96, the baby was delivered by the 'reverse breech extraction approach', and in the remaining 96, by the 'standard approach'. Extension of uterine incision occurred in 18 participants (18.8%) in the reverse breech extraction approach group, and 46 (47.9%) in the standard approach group (p = .0003). Two women (2.1%) in the reverse breech extraction approach group needed blood transfusion and 11 (11.5%) in the standard approach group (p = .012). Pyrexia developed in 3 participants (3.1%) in the reverse breech extraction approach group, and 19 (19.8%) in the standard approach group (p = .0006). Wound infection occurred in 2 women (2.1%) in the reverse breech extraction approach group, and 12 (12.5%) in the standard approach group (p = .007). Apgar score pushing the fetal head up through the vagina.

    Delayed postpartum haemorrhage due to uterine atony after caesarean section was occurring in women in our recovery area despite many of them already having an oxytocin infusion running to prevent such a problem. We therefore decided to compare the incidence of such problems for a 2-month period before and after altering our uterotonic policy: in addition to the routine bolus dose of 5 units of oxytocin after delivery of the baby, we added 500 microg of intramuscular ergometrine during abdominal closure. We noticed a reduced number of massive postpartum haemorrhages due to an atonic uterus in the recovery room but an increased incidence of nausea and vomiting. No prophylactic anti-emetic was given during this pilot study. This small study suggests that 50 women would need to be given ergometrine at caesarean section to prevent one delayed massive haemorrhage from uterine atony and four extra women would suffer with vomiting. We feel this is reasonable and now use a prophylactic anti-emetic as well as delaying the ergometrine until closure of the rectus sheath which reduces the incidence of nausea and vomiting.

    To evaluate the effect of a novel communication tool, related to the degree of urgency for Caesarean sections (CSs), on the decision-to-delivery interval for emergency CS. Red CS are very urgent cases corresponding to life-threatening maternal or foetal situations, orange CS are urgent cases and green CS are non-urgent intrapartum CS. We carried out this cohort study in a French maternity hospital. The study included all emergency Caesarean sections during two 6-month periods, before and after introduction of the code. We compared the decision-to-delivery interval of the two study periods. Our study included 174 emergency CS. The mean decision-to-delivery interval after introduction of the code was 31.7 min, significantly shorter (p=0.02) than the 39.6 min interval before introduction of the colour code. Except for the preparation time, each time interval decreased. This included transporting the patient into the operating theatre, and the incision-to-delivery time interval. This study suggests that the use of the three-colour code could significantly shorten the decision-to-delivery interval in emergency CS. Further prospective studies are needed to confirm this result.

    The delivery of a macrosomic infant is associated with a higher risk for maternofoetal complications. Shoulder dystocia is the most feared fetal complication, leading sometimes to a disproportionate use of caesarean section. This study aims to evaluate the interest of preventive caesarean section. We conducted a retrospective study of 400 macrosomic births between February 2010 and December 2012. We also identified cases of infants with shoulder dystocia occurred in 2012 as well as their respective birthweight. Macrosomic infants weighed between 4000g and 4500g in 86.25% of cases and between 4500 and 5000 in 12.25% of cases. Vaginal delivery was performed in 68% of cases. Out of 400 macrosomic births, 9 cases with shoulder dystocia were recorded (2.25%). All of these cases occurred during vaginal delivery. The risk for shoulder dystocia invaginal delivery has increased significantly with the increase in birth weight (p dystocia affectd macrosoic infants in 58% of cases. Shoulder dystocia is not a complication exclusively associated with macrosomia. Screening for risky deliveries and increasing training of obstetricians on maneuvers in shoulder dystocia seem to be the best way to avoid complications.

    Full Text Available Background: Our aim was to determine the service quality of delivered care for people with Caesarean Section and Normal Delivery. Methods: A cross-sectional study was conducted among 200 people who had caesarean section and normal delivery in Al-Zahra Teaching Hospital in Tabriz, north western Iran. Service quality was calculated using: Service Quality = 10 – (Importance × Performance based on importance and performance of service quality aspects from the postpartum women‟s perspective.A hierarchical regression analysis was applied in two steps using the enter method to examine the associations between demographics and SQ scores. Data were analysed using the SPSS-17 software. Results: “Confidentiality”, “autonomy”, “choice of care provider” and “communication” achieved scores at the highest level of quality; and “support group”, “prompt attention”, “prevention and early detection”, “continuity of care”, “dignity”, “safety”, “accessibility and “basic amenities” got service quality score less than eight. Statistically significant relationship was found between service quality score and continuity of care (P=0.008. Conclusion: A notable gap between the participants‟ expectations and what they have actually received in most aspects of provided care. So, there is an opportunityto improve the quality of delivered care.

    2012-01-01

    Full Text Available Eisenmenger′s syndrome is a cyanotic congenital heart disease that includes pulmonary hypertension with reversed or bidirectional shunt associated with septal defects or patent ductus arteriosus. The decreased systemic vascular resistance associated with pregnancy increases the degree of right to left shunting, thereby carrying substantial risk to both the mother and the foetus. The maternal mortality rate of pregnancy in the presence of Eisenmenger′s syndrome is reported to be as high as 30-70%. We present a case of a 22-year-old primigravida with Eisenmenger′s syndrome who gave birth at 37 weeks of gestation via caesarean section to a live female baby under general anaesthesia. On the third post-operative day, the patient developed tachycardia, tachypnoea, hypotension and decrease in oxygen saturation despite supplemental oxygen, clinically suspected pulmonary thromboembolism. We describe the anaesthetic management for caesarean section and its complications in a patient with Eisenmenger′s syndrome. Although pregnancy should be discouraged in women with Eisenmenger′s syndrome, it can be successful.

    A retrospective and comparative study of women delivered by caesarean section over two different 3-year periods was conducted at Olabisi Onabanjo University Teaching Hospital, Sagamu, Nigeria. The caesarean section rate (CSR) increased from 10.3% in 1989-1991 to 23.1% in 2000-2003. The most frequent indication in both periods was different: prolonged/obstructed labour (20.0%) in 1989-1991 and antepartum haemorrhage (14.9%) in 2000-2003. Malpresentation, antepartum haemorrhage and pre-eclampsia/eclampsia were responsible for 51.7% of the difference in the CSR recorded between both periods. The CSR rose from 13.3% to 25.0% while the instrumental vaginal delivery (IVD) rate decreased significantly by 11.4% among the nulliparous women between the periods. Increase in CSR can be attributed mainly to reduction in IVD rate and alteration in the management of labour complications and induction policy. Strategies to reduce the CSR should cut across all indications and focus on encouraging instrumental vaginal deliveries, especially among nulliparous women.

    Low-income and middle-income countries have introduced different health insurance schemes over the past decades, but whether different schemes are associated with different neonatal outcomes is yet unknown. We examined the association between the health insurance coverage scheme and neonatal mortality in Colombia. We used Colombian national vital registration data, including all live births (2 506 920) and neonatal deaths (17 712) between 2008 and 2011. We used Poisson regression models to examine the association between health insurance coverage and the neonatal mortality rate (NMR), distinguishing between women insured via the contributory scheme (40% of births, financed through payroll and employer's contributions), government subsidised insurance (47%) and the uninsured (11%). NMR was lower among babies born to mothers in the contributory scheme (6.13/1000) than in the subsidised scheme (7.69/1000) or the uninsured (8.38/1000). Controlling for socioeconomic and demographic factors, NMRs remained higher for those in the subsidised scheme (OR 1.09, 95% CI 1.05 to 1.14) and the uninsured (OR 1.16, 95% CI 1.10 to 1.23) compared to those in the contributory scheme. These differences increased in models that additionally controlled for caesarean section (C-section) delivery. This increase was due to the higher fraction of C-section deliveries among women in the contributory scheme (49%, compared to 34% for the subsidised scheme and 28% for the uninsured). Health insurance through the contributory system is associated with lower neonatal mortality than insurance through the subsidised system or lack of insurance. Universal health insurance may not be sufficient to close the gap in newborn mortality between socioeconomic groups. Published by the BMJ Publishing Group Limited.

    Variations in caesarean section (CS) between some immigrant groups and receiving country populations have been widely reported. Often, African immigrant women are at higher risk of CS than the receiving population in developed countries. However, evidence about subsequent mode of birth following CS for African women post-migration is lacking. The objective of this study was to examine differences in attempted and successful vaginal birth after previous caesarean (VBAC) for Eastern African immigrants (Eritrea, Ethiopia, Somalia and Sudan) compared with Australian-born women. A population-based observational study was conducted using the Victorian Perinatal Data Collection. Pearson's chi-square test and logistic regression analysis were performed to generate adjusted odds ratios for attempted and successful VBAC. Victoria, Australia. 554 Eastern African immigrants and 24,587 Australian-born eligible women with previous CS having singleton births in public care. 41.5% of Eastern African immigrant women and 26.1% Australian-born women attempted a VBAC with 50.9% of Eastern African immigrants and 60.5% of Australian-born women being successful. After adjusting for maternal demographic characteristics and available clinical confounding factors, Eastern African immigrants were more likely to attempt (OR adj 1.94, 95% CI 1.57-2.47) but less likely to succeed (OR adj 0.54 95% CI 0.41-0.71) in having a VBAC. There are disparities in attempted and successful VBAC between Eastern African origin and Australian-born women. Unsuccessful VBAC attempt is more common among Eastern African immigrants, suggesting the need for improved strategies to select and support potential candidates for vaginal birth among these immigrants to enhance success and reduce potential complications associated with failed VBAC attempt.

    Increasing awareness of the risks of blood transfusion has prompted examination of red cell transfusion practice in obstetrics. A six-month prospective observational study was performed to examine blood transfusion practices in patients undergoing caesarean delivery at three hospitals in Pakistan. In the three hospitals (two private, one public) 3438 caesarean deliveries were performed in the study period. Data were collected on patient demographics, indications for transfusion, ordering physicians, consent, associations with obstetric factors, estimated allowable blood loss, calculated blood loss, pre- and post-transfusion haemoglobin and discharge haemoglobin. A total number of 397 (11.5%) patients who underwent caesarean section received a blood transfusion. The highest transfusion rate of 16% was recorded in the public tertiary care hospital compared to 5% in the two private hospitals. Emergency caesarean delivery and multiparity were associated with blood transfusion (Ptransfusion in 98% of cases. In 343 (86%) patients, blood transfusion was given even when the haemoglobin was >7g/dL. The method for documenting the indication or consent for transfusion was not found in any of the three hospitals. Blood transfusion was prescribed more readily in the public hospital. Identification of a transfusion trigger and the development of institutional guidelines to reduce unnecessary transfusion are required. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Caesarean section (CS) is the most common obstetric surgical procedure, with more than one-third of pregnant women having lower-segment CS. Bladder evacuation is carried out as a preoperative procedure prior to CS. Emerging evidence suggests that omitting the use of urinary catheters during and after CS could reduce the associated increased risk of urinary tract infections (UTIs), catheter-associated pain/discomfort to the woman, and could lead to earlier ambulation and a shorter stay in hospital. To assess the effectiveness and safety of indwelling bladder catheterisation for intraoperative and postoperative care in women undergoing CS. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 December 2013) and reference lists of retrieved studies. Randomised controlled trials (RCTs) comparing indwelling bladder catheter versus no catheter or bladder drainage in women undergoing CS (planned or emergency), regardless of the type of anaesthesia used. Quasi-randomised trials, cluster-randomised trials were not eligible for inclusion. Studies presented as abstracts were eligible for inclusion providing there was sufficient information to assess the study design and outcomes. Two review authors independently assessed studies for eligibility and trial quality, and extracted data. Data were checked for accuracy. The search retrieved 16 studies (from 17 reports). Ten studies were excluded and one study is awaiting assessment. We included five studies involving 1065 women (1090 recruited). The five included studies were at moderate risk of bias.Data relating to one of our primary outcomes (UTI) was reported in four studies but did not meet our definition of UTI (as prespecified in our protocol). The included studies did not report on our other primary outcome - intraoperative bladder injury (this outcome was not prespecified in our protocol).

    Full Text Available Background. In the past decade, the rate of caesarean section (CS has increased dramatically in many parts of the world. At Muhimbili National Hospital (MNH there has been a dramatic rise in the caesarean section rate over the past decade.Objective. To determine the incidence of maternal request for CS and factors associated with intention to request caesarean section at the MNH antenatal clinic.Methods. We conducted a cross-sectional study from August to October 2014. A structured questionnaire gathered participants’ background and obstetric information, perceptions and opinions regarding a request for caesarean section, and the respective reasons for the request. Confidence intervals were calculated and a p-value <0.05 was considered significant.Results. The incidence of CS on maternal request was about 6%. The intention to request for CS in the index pregnancy was 8%. Higher-level education and formal-sector employment had higher odds for requesting CS (p=0.01 and p=0.05, respectively. Half of the participants agreed that maternal request for CS should be allowed; more private patients agreed that it could affect the doctor-patient relationship (p=0.02; more private patients agreed that request for CS was due to fear of losing a child (p=0.03. Previous history of CS was an independent predictor of maternal request for caesarean section (OR 1.7; 95% CI 1.7 - 15.4 and (OR 5.8; 95% CI 1.6 - 20.1, respectively.Conclusion. Maternal requests for CS exist at the national referral hospital in Tanzania. This was associated with factors other than women’s preferences, including perceived fear of child loss and events associated with previous CS.

    Gum chewing has been reported to enhance bowel motility and reduce postoperative ileus (POI). However, the efficacy remains imprecise for women following caesarean section. To summarise and evaluate the current evidence for postoperative gum chewing on the recovery of bowel function following caesarean section. We searched studies from the following electronic databases: PubMed, EMBASE, SCOPUS and Cochrane Library from inception to 30 May 2013. We included randomised controlled trials (RCTs) of women after caesarean section; these RCTs should compared gum chewing with no gum chewing and reported on at least one of the outcomes: time to flatus, time to bowel sound, time to passing stool and length of hospital stay (LOS). Study outcomes were presented as mean differences (for continuous data) with 95% confidence interval (95% CI). The risk of bias in the study results was assessed using the assessment tool from the Cochrane Handbook. Six RCTs including 939 women were included in our meta-analysis. The pooled results demonstrated that gum chewing is superior to no gum chewing with a reduction of 6.42 hours (95% CI -7.55 to -5.29) for time to first flatus, 3.62 hours (95% CI -6.41 to -0.83) for time to first bowel sound, 6.58 hours (95% CI -10.10 to -3.07) for time to first stool and 5.94 hours (95% CI -9.39 to -2.49) for LOS. In addition, no evidence emerged for any side effects caused by gum chewing. The current evidence suggests that gum chewing is associated with early recovery of bowel motility and shorter LOS for women after caesarean section. This safe and inexpensive intervention should be included in routine postoperative care following a caesarean section. © 2014 Royal College of Obstetricians and Gynaecologists.

    To examine trends in the utilisation of facility-based delivery care and caesareans in Morocco between 1987 and 2012, particularly among the poor, and to assess whether uptake increased at the time of introduction of policies or programmes aimed at improving access to intrapartum care. Using data from nationally representative household surveys and routine statistics, our analysis focused on whether women delivered within a facility, and whether the delivery was by caesarean; analyses were stratified by relative wealth quintile and public/private sector where possible. A segmented Poisson regression model was used to assess whether trends changed at key events. Uptake of facility-based deliveries and caesareans in Morocco has risen considerably over the past two decades, particularly among the poor. The rate of increase in facility deliveries was much faster in the poorest quintile (annual increase RR: 1.09; 95% CI: 1.07-1.11) than the richest quintile (annual increase RR: 1.01; 95% CI: 1.02-1.02). A similar pattern was observed for caesareans (annual increase among poorest RR: 1.13; 95% CI: 1.07-1.19 vs. annual increase among richest RR: 1.08; 95% CI: 1.06-1.10). We found no significant acceleration in trend coinciding with any of the events investigated. Morocco's success in improving uptake of facility deliveries and caesareans is likely to be the result of the synergistic effects of comprehensive demand and supply-side strategies, including a major investment in human resources and free delivery care. Equity still needs to be improved; however, the overall trend is positive. © 2015 John Wiley & Sons Ltd.

    To compare the frequency of hypotension of sitting versus lateral position during induction of spinal anesthesia for elective LSCS using Hyperbaric Bupivacaine. Study Design: Randomized control trial. Place and Duration of Study: The study was conducted at Military Hospital Rawalpindi, a tertiary care hospital, after seeking hospital ethics committee permission. Study was carried out for six months, from Nov 2014 to May 2015. Patient and Methods: A total of 130 participants achieving the inclusion criteria were picked up for this study. Patients were randomized into group-S and group-L (65 in each group). Group-S received spinal anesthesia using 0.75% hyperbaric Bupivacaine in sitting position and group-L in left lateral position. Maternal Blood pressure was measured before Induction (baseline) and every 3 min after subarachnoid injection for 15 min and final outcome measured at 15 minutes. Decrease in systolic blood pressure of >20% from baseline or a value <90 mmHg was considered as hypotension. Results: The age of the patients ranged between 25-35 years. Average age of participants were 29.18 +- 2.80 and 29.12 +- 2.52 in group S and L, respectively. In group-S hypotension developed in 34 patients (52.3%) and in group-L hypotension was observed in 20 patients (30.7%), (p=0.013). Mean weight in group-S was 71.77 +- 2.82 and in group-L was 70.91 +- 2.05. Stratification with regard to age and ASA status was carried out. Conclusion: Occurrence of Hypotension was significantly less frequent when spinal anesthesia was induced to patients in the left lateral position, for elective caesarean using 0.75% Hyperbaric Bupivacaine compared to the sitting position.

    A caesarean section (CS) is one of the most common surgical procedures performed in the world, for which there are minimal variations in the surgical approach. During the last few years the "skin-to-skin" CS, also coined "natural" or "gentle" CS, is on the rise; parental participation, slow delivery and direct skin-to-skin contact are important aspects. Most Dutch hospitals offer some form of "skin-to-skin" CS but there are local differences in availability and performance of the procedure. Since 2011, the standard procedure in the Martini Hospital in Groningen is the "skin-to-skin" CS (for both elective and emergency CS, 24/7). We describe our method and share our retrospective data, and demonstrate that this procedure does not result in more complications for mother or baby.

  5. Acute Chest Syndrome in Sickle Cell Disease Patients Post Caesarean Delivery

    2016-02-01

    Full Text Available Sickle cell disease (SCD is the most common inherited disease worldwide and is associated with anaemia and intermittent painful crisis. Pregnant women who are affected are known to have increased maternal and fetal mortality and morbidity. Acute chest syndrome (ACS is an uncommon but serious complication in pregnant women with SCD that can lead to death. We present two cases of patients with SCD, both of whom had severe ACS within 24 hours post Caesarean section. By accurate diagnosis and appropriate management by a multidisciplinary team, both mothers and fetuses had excellent outcomes. It is suggested that prompt recognition of ACS in a pregnant woman with SCD and collaborative medical and obstetric management are essential to optimize maternal and fetal outcomes.

    The uteroplacental blood flow was measured before and during epidural anaesthesia for caesarean section in 11 woman. The blood flow was measured with dynamic placental scintigraphy. After an i.v. injection of indium-113m chloride, the gamma radiation over the placenta was recorded with a computer-linked scintillation camera. The uteroplacental blood flow could be calculated from the isotope accumulation curve. The anaesthesia was performed with bupivacaine plain 0.5%, 18-22 ml and a preload of a balanced electrolyte solution 10 ml/kg b.w. was given. The placental blood flow decreased in eight patients and increased in three with a median change of -21%, not being statistically significant. No correlation between maternal blood pressure and placental blood flow was found. (author).

    2018-01-01

    Full Text Available We present a 32-year-old G1P0 woman at 32 weeks and two days gestation with new onset paraplegia, hyperreflexia, and sensory disturbance that gradually progressed over the past month and acutely worsened over the last 24 hours. MRI revealed a demyelinating process of the thoracic spine and diffuse cervicothoracic cord oedema. After 7 days, her foetus developed recurrent heart rate decelerations and an emergent caesarean section was performed. On airway exam, she was Mallampati 3 with a short thyromental distance. She reported fasting overnight and into the morning. Our choice was between performing neuraxial anaesthesia in the setting of an acute demyelinating process of her spinal cord versus general anaesthesia on a patient at risk of aspiration with a potentially difficult airway. Given the potential complications of neuraxial anaesthesia, we utilized rocuronium to perform a rapid sequence induction of general anaesthesia with endotracheal intubation.

    Myasthenia gravis is an autoimmune disorder that is characterized by muscle weakness that fluctuates, worsening with exertion, and improving with rest. Diagnosis of myasthenia gravis is made following clinical and physical examination and is confirmed by serum immunoassays to measure autoantibody levels. Myasthenia gravis especially when associated with pregnancy is a high-risk disease, and its course is unpredictable. We described the second report about use of sugammadex after rocuronium for a caesarean delivery with myasthenia gravis, but, unlike our case that formerly was diagnosed with myasthenia gravis, the patient was extubated on postoperative successfully and we did not encounter any respiratory problems.

    OBJECTIVES: The aim of this study was to estimate the effects of risk factors on elective and emergency caesarean section (CS) and to estimate the between-hospital variation of risk-adjusted CS proportions. DESIGN: Historical registry-based cohort study. SETTINGS AND PARTICIPANTS: The study......, for example, body mass index, parity, age and size of maternity unit and (2) risk-adjusted proportions of elective and emergency CS to evaluate between-hospital variation. RESULTS: The CS proportion was stable at 20%-21%, but showed wide variation between units, even in adjusted models. Large units performed...... CSs and one unit fewer CSs than expected. CONCLUSION: The main risk factors for elective CS were breech presentation and previous CS; for emergency CS they were breech presentation and cephalopelvic disproportion. The proportions of CS were stable during the study period. We found variation in risk...

  12. Anaesthesia for caesarean section in a patient with Sturge-Weber syndrome following acute neurological deterioration.

    Sturge-Weber syndrome consists of facial capillary malformation (port-wine stain) and abnormal blood vessels in the brain or eye. Seizures, developmental delay and intracranial and airway angiomata are principal concerns. We report a 28-year-old primiparous woman at 41 weeks of gestation with Sturge-Weber syndrome who developed unilateral weakness, aphasia, blurred vision and confusion. Preeclampsia was excluded. Neuroimaging showed left sided cerebral oedema and a right parieto-occipital lesion, most likely an angioma. Caesarean section was planned to avoid the risk of angioma rupture during labour. General anesthesia was avoided due to the haemodynamic response to laryngoscopy and reports of seizure-related mortality. Despite the possibility of raised intracranial pressure and precipitation of cerebral herniation, a lumbar epidural block was administered but failed. A subarachnoid block was successfully performed and a healthy infant delivered. The choice of anaesthesia was strongly influenced by detailed radiological investigations and multidisciplinary participation.

    Primarily, to assess the performance of three statistical models in predicting successful vaginal birth in patients attempting a trial of labour after one previous lower segment caesarean section (TOLAC). The statistically most reliable models were subsequently subjected to validation testing in a local antenatal population. A retrospective observational study was performed with study data collected from the Northern Ireland Maternity Service Database (NIMATs). The study population included all women that underwent a TOLAC (n=385) from 2010 to 2012 in a regional UK obstetric unit. Data was collected from the Northern Ireland Maternity Service Database (NIMATs). Area under the curve (AUC) and correlation analysis was performed. Of the three prediction models evaluated, AUC calculations for the Smith et al., Grobman et al. and Troyer and Parisi Models were 0.74, 0.72 and 0.65, respectively. Using the Smith et al. model, 52% of women had a low risk of caesarean section (CS) (predicted VBAC >72%) and 20% had a high risk of CS (predicted VBAC <60%), of whom 20% and 63% had delivery by CS. The fit between observed and predicted outcome in this study cohort using the Smith et al. and Grobman et al. models were greatest (Chi-square test, p=0.228 and 0.904), validating both within the population. The Smith et al. and Grobman et al. models could potentially be utilized within the UK to provide women with an informed choice when deciding on mode of delivery after a previous CS.

    Full Text Available In order to meet the Sustainable Development Goal to decrease maternal mortality, increased access to obstetric interventions such as Caesarean sections (CS is of critical importance. As a result of women's limited access to routine and emergency obstetric services in Nigeria, the country is a major contributor to the global burden of maternal mortality. In this analysis, we aim to establish rates of CS and determine socioeconomic or medical risk factors associated with having a CS in Enugu, southeast Nigeria.Data for this study originated from the Healthy Beginning Initiative study. Participant characteristics were obtained from 2300 women at baseline via a semi-structured questionnaire. Only women between the ages of 17-45 who had singleton deliveries were retained for this analysis. Post-delivery questionnaires were used to ascertain mode-of-delivery. Crude and adjusted logistic regressions with Caesarean as the main outcome are presented.In this sample, 7.22% women had a CS. Compared to women who lived in an urban setting, those who lived in a rural setting had a significant reduction in the odds of having a CS (aOR: 0.58; 0.38-0.89. Significantly higher odds of having a CS were seen among those with high peripheral malaria parasitemia compared to those with low parasitemia (aOR: 1.54; 1.04-2.28.This study revealed that contrary to the increasing trend in use of CS in low-income countries, women in this region of Nigeria had limited access to this intervention. Increasing age and socioeconomic proxies for income and access to care (e.g., having a tertiary-level education, full-time employment, and urban residence were shown to be key determinants of access to CS. Further research is needed to ascertain the obstetric conditions under which women in this region receive CS, and to further elucidate the role of socioeconomic factors in accessing CS.

    In most regions worldwide, caesarean section (CS) rates are increasing. In these settings, new strategies are needed to reduce CS rates. To identify, critically appraise and synthesise studies using the Robson classification as a system to categorise and analyse data in clinical audit cycles to reduce CS rates. Medline, Embase, CINAHL and LILACS were searched from 2001 to 2016. Studies reporting use of the Robson classification to categorise and analyse data in clinical audit cycles to reduce CS rates. Data on study design, interventions used, CS rates, and perinatal outcomes were extracted. Of 385 citations, 30 were assessed for full text review and six studies, conducted in Brazil, Chile, Italy and Sweden, were included. All studies measured initial CS rates, provided feedback and monitored performance using the Robson classification. In two studies, the audit cycle consisted exclusively of feedback using the Robson classification; the other four used audit and feedback as part of a multifaceted intervention. Baseline CS rates ranged from 20 to 36.8%; after the intervention, CS rates ranged from 3.1 to 21.2%. No studies were randomised or controlled and all had a high risk of bias. We identified six studies using the Robson classification within clinical audit cycles to reduce CS rates. All six report reductions in CS rates; however, results should be interpreted with caution because of limited methodological quality. Future trials are needed to evaluate the role of the Robson classification within audit cycles aimed at reducing CS rates.

    To evaluate caesarean section (CS) rates and moderate to severe hypoxaemic ischaemic encephalopathy (HIE) rates with other core intra-partum outcomes following reconfiguration of maternity services in Cardiff, South Wales, UK. Cohort study of births from 2006 to 2015. A University tertiary referral centre for foetal and maternal medicine with 6000 births/year, University Hospital of Wales, United Kingdom. Data relating to births from 1 January 2006 to 31 December 2015 were extracted from the computerized maternity database on a yearly basis. Case notes of all mothers and babies for the same duration were hand searched for documentation of HIE. HIE data was also collected prospectively by neonatologist (SC) and obstetrician (PA). Incidence of caesarean section births, babies with moderate to severe HIE, instrumental vaginal births, obstetric anal sphincter injuries (OASIS) associated with instrumental delivery, and major post-partum haemorrhage (MPPH) of 2500 mL or more. During this 10-year period, a downward trend in emergency CS rate was seen from 15.6% in 2006 to 10.5% in 2015, reducing total CS rate from 25.5% in 2006 to 21.2% in 2015. A downward trend in the incidence of moderate and severe HIE was seen over the same period. There was an increase in operative vaginal births (OVB) from 12.8% to 15%. The rate of spontaneous vaginal births (SVB) remained stable. The incidence of OASIS remained constant and MPPH rate has fallen. Following amalgamation of two medium sized obstetric units and the opening of a Midwifery Led Unit (MLU), core intrapartum outcomes have improved. Contributing factors are the introduction of regular multidisciplinary training with enhanced team working, compulsory education for obstetricians and midwives on cardiotocograph (CTG) interpretation, increased consultant presence on delivery suite, robust risk management systems and broad multidisciplinary agreement on clinical guidelines promoting vaginal birth.

    Positioning of the patient during and after surgery can have significant implications on recovery. Therefore, the purpose of the present study was to determine the influence of placing patients in a lateral decubitus position for 15 min after combined use of hyperbaric and hypobaric ropivacaine and assess hemodynamic characteristics during spinal anesthesia for caesarean section. One hundred-forty patients undergoing elective cesarean delivery with combined use of hyperbaric and hypobaric ropivacaine were included in the present study. Patients meeting inclusion criteria (134) were randomly allocated into Group A: immediately turned to the supine position after induction of spinal anesthesia (n = 67) or Group B: maintained in a lateral decubitus position for 15 min before being turned to the supine position (n = 67). Primary endpoints of the study were to compare hemodynamic characteristics and sensory blockade levels in the two groups, while a secondary endpoint was to observe the incidence of complications. Both groups showed similar effects of the combined anesthetic treatment. Incidence of hypotension (43% vs 18%, P = 0.001), systolic AP hyperbaric and hypobaric ropivacaine had satisfactory anesthetic effects and a more stable hemodynamic characteristic than either drug used alone. Maintaining the patient in a lateral decubitus position for 15 min can significantly decrease the incidence of hypotension.

  19. Repeated causal decision making.

    2013-01-01

    Many of our decisions refer to actions that have a causal impact on the external environment. Such actions may not only allow for the mere learning of expected values or utilities but also for acquiring knowledge about the causal structure of our world. We used a repeated decision-making paradigm to examine what kind of knowledge people acquire in such situations and how they use their knowledge to adapt to changes in the decision context. Our studies show that decision makers' behavior is strongly contingent on their causal beliefs and that people exploit their causal knowledge to assess the consequences of changes in the decision problem. A high consistency between hypotheses about causal structure, causally expected values, and actual choices was observed. The experiments show that (a) existing causal hypotheses guide the interpretation of decision feedback, (b) consequences of decisions are used to revise existing causal beliefs, and (c) decision makers use the experienced feedback to induce a causal model of the choice situation even when they have no initial causal hypotheses, which (d) enables them to adapt their choices to changes of the decision problem.

  20. An Examination of Women Experiencing Obstetric Complications Requiring Emergency Care: Perceptions and Sociocultural Consequences of Caesarean Sections in Bangladesh

    2012-01-01

    Little is known about the physical and socioeconomic postpartum consequences of women who experience obstetric complications and require emergency obstetric care (EmOC), particularly in resource-poor countries such as Bangladesh where historically there has been a strong cultural preference for births at home. Recent increases in the use of skilled birth attendants show socioeconomic disparities in access to emergency obstetric services, highlighting the need to examine birthing preparation and perceptions of EmOC, including caesarean sections. Twenty women who delivered at a hospital and were identified by physicians as having severe obstetric complications during delivery or immediately thereafter were selected to participate in this qualitative study. Purposive sampling was used for selecting the women. The study was carried out in Matlab, Bangladesh, during March 2008–August 2009. Data-collection methods included in-depth interviews with women and, whenever possible, their family members. The results showed that the women were poorly informed before delivery about pregnancy-related complications and medical indications for emergency care. Barriers to care-seeking at emergency obstetric facilities and acceptance of lifesaving care were related to apprehensions about the physical consequences and social stigma, resulting from hospital procedures and financial concerns. The respondents held many misconceptions about caesarean sections and distrust regarding the reason for recommending the procedure by the healthcare providers. Women who had caesarean sections incurred high costs that led to economic burdens on family members, and the blame was attributed to the woman. The postpartum health consequences reported by the women were generally left untreated. The data underscore the importance of educating women and their families about pregnancy-related complications and preparing families for the possibility of caesarean section. At the same time, the health

    OBJECTIVE: Caesarean section is one of the most commonly performed major operations on women worldwide. Operative morbidity includes haemorrhage, anaemia, blood transfusion and in severe cases, maternal death. Various clinical guidelines address oxytocin use at the time of caesarean section. We previously reported wide variation in practice amongst clinicians in the United Kingdom in the use of oxytocin at caesarean section. The aim of this current study was to determine whether the variation in approach is universal across the individual countries of Great Britain and Ireland and whether this reflects differences in interpretation and implementation of clinical practice guidelines. STUDY DESIGN: We conducted a survey of practice in the five individual countries of Great Britain and Ireland. A postal questionnaire was sent to all lead consultant obstetricians and anaesthetists with responsibility for the labour ward. We explored the use of oxytocin bolus and infusion, the measurement of blood loss at caesarean section and the rates of major haemorrhage. Existing clinical guidelines from the National Institute for Clinical Excellence (NICE), the Royal College of Obstetricians and Gynaecologists (RCOG) and ALSO (Advanced Life Support in Obstetrics) were used to benchmark reported practice against recommended practice for the management of blood loss at caesarean section. RESULTS: The response rate was 82% (391 respondents). Use of a 5 IU oxytocin bolus was reported by 346 respondents (85-95% for individual countries). In some countries, up to 14% used a 10 IU oxytocin bolus despite recommendations against this. Routine use of an oxytocin infusion varied greatly between countries (11% lowest-55% highest). Marked variations in choice of oxytocin regimens were noted with inconsistencies in the country-specific recommendations, e.g. NICE (which covers England and Wales) recommends a 30 IU oxytocin infusion over 4h, but only 122 clinicians (40%) used this.

    women who birth in private facilities in Australia are more likely to have a caesarean birth than women who birth in public facilities and these differences remain after accounting for sector differences in the demographic and health risk profiles of women. However, the extent to which women's preferences and/or freedom to choose their mode of birth further account for differences in the likelihood of caesarean birth between the sectors remains untested. women who birthed in Queensland, Australia during a two-week period in 2009 were mailed a self-report survey approximately 3 months after birth. Seven hundred and fifty-seven women provided cross-sectional retrospective data on where they birthed (public or private facility), mode of birth (vaginal or caesarean) and risk factors, along with their preferences and freedom to choose their mode of birth. A hierarchical logistic regression was conducted to determine the extent to which maternal risk and freedom to choose one's mode of birth explain sector differences in the likelihood of having a caesarean birth. while there was no sector difference in women's preference for mode of birth, women who birthed in private facilities had higher odds of feeling able to choose either a vaginal or caesarean birth, and feeling able to choose only a caesarean birth. Women had higher odds of having caesarean birth if they birthed in private facilities, even after accounting for significant risk factors such as age, body mass index, previous caesarean and use of assisted reproductive technology. However, there was no association between place of birth and odds of having a caesarean birth after also accounting for freedom to choose one's mode of birth. these findings call into question suggestions that the higher caesarean birth rate in the private sector in Australia is attributable to increased levels of obstetric risk among women birthing in the private sector or maternal preferences alone. Instead, the determinants of sector

    To assess the mode of delivery and Caesarean Section (CS) rate after successful External Cephalic Version (ECV). A matched case-control study. Data were gathered from a tertiary care university hospital register from 1996-2015. All pregnant women who delivered after successful External Cephalic Version (ECV). Among 643 women who attempted ECV, we identified 198 with successful ECVs and compared them with the next two women who presented for labor management with spontaneous cephalic presentation, matching for delivery date, maternal age, parity, body mass index, and delivery history using univariate and stepwise logistic regression. The main outcome measure was the risk of caesarean. The caesarean section rate was higher after successful ECV (respectively 20.7% versus 7.07%, P<0.05). Caesarean section for abnormal fetal head position (forehead, bregma, face) was higher after successful ECV (28.6% versus 0%). After adjustment for matching and confounding variables (variation of the caesarean section rate over the study period, gestational maternal complications, antepartum fetal complications, term of delivery, induction of labor, oxytocin use for dystocia, neonatal cephalic perimeter), a successful ECV increased the risk of caesarean section (adjusted OR 3.17, 95% CI 1.86-5.46). By stratifying on week, a trend for increased risk for caesarean section was observed at the week after ECV and at post term (28.6% before 37+6, 14.8% at 38+0-38+6, 13.8% at 39+0-39+6, 14.2% at 40+0-40+6 and 33.3% beyond 41+0 weeks' gestation, P=0.06). Women who have a successful ECV are at increased risk of caesarean section compared with women who experience spontaneous cephalic presentation. Copyright © 2017 Elsevier Masson SAS.

    Full Text Available Abstract Background There has been a marked increase in the number of Caesarean sections in many countries during the last decades. In several countries, Caesarean sections are carried out in more than 20 per cent of births. These high Caesarean section rates give cause for concern, both from an economic and a medical perspective. A general opinion among epidemiologists is that the increase in the number of Caesarean sections during the last decade has been greater than could be expected in relation to medical risk factors. Therefore, other explanations must be sought. We studied one potential explanation; the effect that the increase in hospital revenue per bed during the period 1976-2005 has had on the Caesarean section rate in Norway. During this period, hospital revenue increased by about 260% (adjusted for inflation. Methods The analyses were carried out using data from the Medical Birth Registry 1976-2005 from Norway. The data were merged with data about hospital revenue, which were obtained from Statistics Norway. The analyses were carried out using annual data from 46 hospitals. A fixed effect regression model was estimated. Relevant medical control variables were included. Results The elasticity of the Caesarean section rate with respect to hospital revenue per bed was 0.13 (p Conclusion The increase in hospital revenue explains only a small part of the increase in the Caesarean section rate in Norway during the last three decades. The increase in the Caesarean section rate is considerably greater than could be expected, based on the increase in hospital revenue alone. The strength of our study is that we have estimated a cause and effect relationship. This was done by using fixed effects for hospitals, a lagged revenue variable and by including an extensive set of control variables for the risk factors of the mother and the baby.

    This study aims to assess the level of self-esteem of newly delivered mothers who had caesarean section (CS) and evaluate the sociodemographic and obstetrics correlates of low self-esteem in them. Newly delivered mothers who had CS (n = 109) and who had spontaneous vaginal delivery (SVD) (n = 97) completed questionnaires on sociodemographic and obstetrics variables within 1 week of delivery. They also completed the Rosenberg self-esteem scale. RESULTS. Women with CS had statistically significant lower scores on the self-esteem scale than women with SVD (p = 0.006). Thirty (27.5%) of the CS group were classified as having low self-esteem compared with 11 (11.3%) of the SVD group (p = 004). The correlates of low self-esteem in the CS group included polygamy (odd ratio (OR) 4.99, 95% confidence interval (95% CI) 1.62-15.33) and emergency CS (OR 4.66, 95% CI 1.55-16.75). CS in South-Western Nigerian women is associated with lowered self-esteem in the mothers.

  6. Expansion of protein domain repeats.

    Full Text Available Many proteins, especially in eukaryotes, contain tandem repeats of several domains from the same family. These repeats have a variety of binding properties and are involved in protein-protein interactions as well as binding to other ligands such as DNA and RNA. The rapid expansion of protein domain repeats is assumed to have evolved through internal tandem duplications. However, the exact mechanisms behind these tandem duplications are not well-understood. Here, we have studied the evolution, function, protein structure, gene structure, and phylogenetic distribution of domain repeats. For this purpose we have assigned Pfam-A domain families to 24 proteomes with more sensitive domain assignments in the repeat regions. These assignments confirmed previous findings that eukaryotes, and in particular vertebrates, contain a much higher fraction of proteins with repeats compared with prokaryotes. The internal sequence similarity in each protein revealed that the domain repeats are often expanded through duplications of several domains at a time, while the duplication of one domain is less common. Many of the repeats appear to have been duplicated in the middle of the repeat region. This is in strong contrast to the evolution of other proteins that mainly works through additions of single domains at either terminus. Further, we found that some domain families show distinct duplication patterns, e.g., nebulin domains have mainly been expanded with a unit of seven domains at a time, while duplications of other domain families involve varying numbers of domains. Finally, no common mechanism for the expansion of all repeats could be detected. We found that the duplication patterns show no dependence on the size of the domains. Further, repeat expansion in some families can possibly be explained by shuffling of exons. However, exon shuffling could not have created all repeats.

    Introduction Approximately 25% of all babies in North America are delivered via Caesarean section (C-section). Though a common surgical procedure, C-section recovery can be painful. Opioids, specifically codeine, are commonly used to ease pain; however, its active metabolite, morphine, passes into breast milk, and may produce unwanted side effects in neonates; therefore, alternatives to opioids are being sought. Reiki is an ancient Japanese form of healing where practitioners transfer healing energy through light touch and positive healing intention. Although 1.2 million Americans use reiki to reduce pain or depression, there is a lack of strong evidence supporting its effectiveness. A recent systematic review showed existing studies to be of poor methodological quality, with the common limitation of lack of blinding. To overcome this issue, the authors used distant reiki to assess its effectiveness in reducing pain following an elective C-section. Methods In this randomised, double-blinded study, women who underwent an elective C-section were allocated to either usual care (control, n=40) or three distant reiki sessions in addition to usual care (n=40). Pain was assessed using a visual analogue scale (VAS). The primary endpoint was the Area Under the VAS-Time Curve (AUC) for days 1–3. Secondary measures included: the proportion of women who required opioid medications and dose consumed, rate of healing and vital signs. Results AUC for pain was not significantly different in the distant reiki and control groups (mean±SD; 212.1±104.7 vs 223.1±117.8; p=0.96). There were no significant differences in opioid consumption or rate of healing; however, the distant reiki group had a significantly lower heart rate (74.3±8.1 bpm vs 79.8±7.9 bpm, p=0.003) and blood pressure (106.4±9.7 mm Hg vs 111.9±11.0 mm Hg, p=0.02) post surgery. Conclusion Distant reiki had no significant effect on pain following an elective C-section. Clinical Trial Registration

    The large majority of caesarean sections in the UK are now carried out under neuraxial anaesthesia. Although this technique is widely accepted as being the safest option in most circumstances, the use of regional anaesthesia increases the risk of patients experiencing intra-operative discomfort or pain. Pain during operative obstetric delivery is the commonest successful negligence claim relating to regional anaesthesia against obstetric anaesthetists in the UK. In the following article, using a database of over 360 cases spanning 21 years, we break down and examine the recurrent components of medicolegal claims concerning pain during caesarean section and consider how anaesthetists might avoid litigation. © 2017 The Association of Anaesthetists of Great Britain and Ireland.

    to explore midwives' experiences and perceptions of skin-to-skin contact between mothers and their healthy full-term infants immediately and during the first day after caesarean section. qualitative interviews with semi-structured questions. eight midwives at three different hospitals in Stockholm participated in the study. All participants provided care for mothers and their newborn infants after caesarean birth. transcribed material was analysed and interpreted using qualitative content analysis. The analysis yielded the theme 'fighting an uphill battle'. skin-to-skin contact was considered to be important, and something that midwives strove to implement as a natural element of postnatal care. However, in daily practice, midwives experienced many obstacles to such care, such as lack of knowledge among parents and other professionals about the benefits of skin-to-skin contact, the mother's condition after the caesarean section, and other organisational difficulties (e.g. collaboration with other professionals, lack of time). Introducing more skin-to-skin care was a challenge for the midwives, who sometimes felt both dismissed and disappointed when they tried to communicate the benefits of this type of care. skin-to-skin contact is not prioritised because many health care practitioners are unaware of its positive effects, and their care reflects this lack of knowledge. There is a need for education among all health care practitioners involved in caesarean procedures. Another difficulty is that many parents are unaware of the benefits of skin-to-skin contact. Maternity outpatient clinics need to inform parents about the benefits of such care, so mothers will understand the importance of skin-to-skin contact. Copyright © 2014 Elsevier Ltd.

    During a one year period, 4910 radiographs of 55780 films were repeated. The objective of our study was to analyse and to classify the causes in order to minimize the repeats, cut the expenses and to provide optimal radiographs for accurate diagnosis. Analysis of the different factors revealed that, 43.6% of film repeats in our service were due to faults in exposure factors, centering comprises 15.9% of the repeats, while too much collimation was responsible for 7.6% of these repeats. All of which can be decreased by awareness and programmed training of technicians. Film blurring caused by patient motion was also responsible for 4.9% for radiographs reexamination, which can be minimized by detailed explanation to the patient and providing the necessary privacy. Fogging of X-Ray films by improper storage or inadequate handling or processing faults were responsible for 14.5% in repeats in our study. Methods and criteria for proper storage and handling of films were discussed. Recommendation for using modern day-light and laser processor has been high lighted. Artefacts are noticeably high in our cases, due to spinal dresses and frequent usage of precious metals for c osmotic purposes in this part of the world. The repeated films comprise 8.8% of all films We conclude that, the main factor responsible for repeats of up to 81.6% of cases was the technologists, thus emphasizing the importance of adequate training of the technologists.

    1981-01-01

    A ten megabit per second serial data repeater system has been developed for the 6.28km Tevatron accelerator. The repeaters are positioned at each of the thirty service buildings and accommodate control and abort system communications as well as distribution of the Tevatron time and energy clocks. The repeaters are transparent to the particular protocol of the transmissions. Serial data are encoded locally as unipolar two volt signals employing the self-clocking Manchester Bi-Phase code. The repeaters modulate the local signals to low-power bursts of 50 MHz rf carrier for the 260m transmission between service buildings. The repeaters also demodulate the transmission and restructure the data for local utilization. The employment of frequency discrimination techniques yields high immunity to the characteristic noise spectrum

    Quantum communication holds promise for unconditionally secure transmission of secret messages and faithful transfer of unknown quantum states. Photons appear to be the medium of choice for quantum communication. Owing to photon losses, robust quantum communication over long lossy channels requires quantum repeaters. It is widely believed that a necessary and highly demanding requirement for quantum repeaters is the existence of matter quantum memories. Here we show that such a requirement is, in fact, unnecessary by introducing the concept of all-photonic quantum repeaters based on flying qubits. In particular, we present a protocol based on photonic cluster-state machine guns and a loss-tolerant measurement equipped with local high-speed active feedforwards. We show that, with such all-photonic quantum repeaters, the communication efficiency scales polynomially with the channel distance. Our result paves a new route towards quantum repeaters with efficient single-photon sources rather than matter quantum memories. PMID:25873153

    This study investigates features of visual acuity chart design and acuity testing scoring methods which affect the validity and repeatability of visual acuity measurements. Visual acuity was measured using the Sloan and British Standard letter series, and Landolt rings. Identifiability of the different letters as a function of size was estimated, and expressed in the form of frequency-of-seeing curves. These functions were then used to simulate acuity measurements with a variety of chart designs and scoring criteria. Systematic relationships exist between chart design parameters and acuity score, and acuity score repeatability. In particular, an important feature of a chart, that largely determines the repeatability of visual acuity measurement, is the amount of size change attributed to each letter. The methods used to score visual acuity performance also affect repeatability. It is possible to evaluate acuity score validity and repeatability using the statistical principles discussed here.

    Although term breech presentation is a relatively rare condition (3-5% of all births), it continues to be an important indication for caesarean section and has contributed to its increased use. Risk of complications may be increased for both mother and foetus in such a situation. Vaginal delivery of a breech presenting foetus is complex and may involve many difficulties, so today there is a general consensus that planned caesarean section is better than planned vaginal birth for the foetus in breech presentation at term. External cephalic version is one of the most effective procedures in modern obstetrics. It involves the external manipulation of the foetus from the breech into the cephalic presentation. A successful manoeuvre can decrease costs by avoiding operative deliveries and decreasing maternal morbidity. The aim of the present study is to evaluate the effectiveness of this obstetric manoeuvre to increase the proportion of vertex presentation among foetuses that were formerly in the breech position near term, so as to reduce the caesarean section rate. The safety of the version is also showed. From 1999 to 2002, 89 women with foetal breech presentation underwent external cephalic version at the Department of Obstetrics and Gynaecology of the Brescia University. The gestational age was 36.8+/-0.8 weeks. The following variables have been taken into consideration: breech variety, placental location, foetal back position, parity, amount of amniotic fluid and gestational age. Every attempt was performed with a prior use of an intravenous drip of Ritodrine, and foetal heart rate was monitored continuously with cardiotocogram. The success rate of the procedure was 42.7% (n=38). No maternal or foetal complication or side effects occurred, both during and after the manoeuvre, except a transient foetal bradycardia that resolved spontaneously. Only one spontaneous reversion of the foetus occurred before delivery. Of all the women that underwent a successful version

    Full Text Available Abstract Background Haemorrhage from obstetric causes is the most common cause of maternal mortality in the developing world. Prevention of mortality from haemorrhage will necessarily involve prompt blood transfusions among other life saving measures. There are however limited stocks of fresh or stored blood in many health care facilities in Sub Saharan Africa. Caesarean section has been identified as a common indication for blood transfusion in obstetrics practice and its performance is often delayed by non availability of blood in our centre. An evaluation of blood reservation and use at caesarean sections in a tertiary maternity unit in Lagos, south western Nigeria should therefore assist in formulating the most rational blood transfusion policies. Methods Case records of 327 patients who had elective and emergency caesarian sections at the Lagos State University Teaching Hospital between 1st October and 31st December 2007 were reviewed. Data pertaining to age, parity, booking status, type and indication for Caesarean section, pre- and post-operative packed cell volume, blood loss at surgery, units of blood reserved in the blood bank, unit(s of blood transfused and duration of hospital stay was extracted and the data analysed. Results There were 1056 deliveries out of which 327 (31% were by Caesarean section. During the study period, a total of 654 units of blood were reserved in the blood bank and subsequently made available in theatre. Out of this number, only 89 (13.6% were transfused to 41 patients. Amongst those transfused, twenty-six (54% were booked and 31 (75.6% had primary caesarian section. About 81% of those transfused had emergency caesarean section. The most common indication for surgery among those transfused were placenta praevia (9 patients with 21 units of blood and cephalo-pelvic disproportion (8 patients with 13 units. Conclusion Even though a large number of units of blood was reserved and made available in the theatre at

    Full Text Available Background: Oxytocin is widely used for the prevention of postpartum haemorrhage. In the setting of Caesarean section (CS, the dosage and mode of administrating oxytocin differs according to different guidelines. Inappropriate oxytocin doses have been identified ascontributory to some cases of maternal deaths. The main aim of this study was to audit the current standard of clinical practice with regard to the use of oxytocin during CS at a referral hospital in Botswana.Methods: A clinical audit of pregnant women having CS and given oxytocin at the time of the operation was conducted over a period of three months. Data included indications for CS, oxytocin dose regimen, prescribing clinician’s designation, type of anaesthesia for the CS and estimated blood loss.Results: A total of 139 case records were included. The commonest dose was 20 IU infusion (31.7%. The potentially dangerous regimen of 10 IU intravenous bolus of oxytocin was used in 12.9% of CS. Further doses were utilized in 57 patients (41%. The top three indications forCS were fetal distress (36 patients, 24.5%, dystocia (32 patients, 21.8% and a previous CS (25 patients, 17.0%. Estimated blood loss ranged from 50 mL – 2000 mL.Conclusion: The use of oxytocin during CS in the local setting does not follow recommended practice. This has potentially harmful consequences. Education and guidance through evidencebased national guidelines could help alleviate the problem.

    Full Text Available Objectives: This study was undertaken to assess the degree of agreement amongst obstetricians regarding decisions to perform emergency Caesarean section (CS procedures at a university hospital. Methods: This retrospective clinical audit was carried out on 50 consecutive emergency CS procedures performed between November 2012 and March 2013 on women with singleton pregnancies at the Sultan Qaboos University Hospital in Muscat, Oman. Data on each procedure were collected from electronic patient records and independently reviewed by six senior obstetricians to determine agreement with the decision. Results: Of the 50 women who underwent CS procedures, the mean age was 28.9 ± 5.1 years and 48% were primigravidae. A total of 65% of the CS procedures were category I. The most common indications for a CS was a non-reassuring fetal heart trace (40% and dystocia (32%. There was complete agreement on the decision to perform 62% of the CS procedures. Five and four obstetricians agreed on 80% and 95% of the procedures, respectively. The range of disagreement was 4–20%. Disagreement occurred primarily with category II and III procedures compared to category I. Additionally, disagreement occurred in cases where the fetal heart trace pattern was interpreted as an indication for a category II CS. Conclusion: The majority of obstetricians agreed on the decisions to perform 94% of the emergency CS procedures. Obstetric decision-making could be improved with the implementation of fetal scalp pH testing facilities, fetal heart trace interpretation training and cardiotocography review meetings.

The study took place in a tertiary referral maternity hospital. Women who had a CS at full dilatation were included. Clinical and demographic details were recorded. There were 199 cases. The average age was 30.3 years and average BMI was 25.8kg\\/m2. There were 79.9 % (159) primigravidas and 20.1% (40) multigravidas. The average gestation at delivery was 39.4 weeks. Labour was induced in 46.9 % (92) and spontaneous in 53.8% (107). Oxytocin was used in 67.8 % (135). An instrumental delivery was attempted in 46.7 % (93). The rate of malposition was 46.5 % (92). The average birthweight was 3,629g and 9 babies weighed ≥4.5kg. The average estimated blood loss (EBL) was 665mls and 34 had EBL>1L. Most had an oxytocin infusion (141). Other uterotonic agents were used in 70 women. Seven women had blood transfusions. The highest rate of CS at full dilatation was in primigravidas due to malposition. There was a low rate of major obstetric haemorrhage.

    Full Text Available BackgroundAlthough little data are available concerning safety for newborns, family-centered caesarean sections (FCS are increasingly implemented. With FCS mothers can see the delivery of their baby, followed by direct skin-to-skin contact. We evaluated the safety for newborns born with FCS in the Leiden University Medical Center (LUMC, where FCS was implemented in June 2014 for singleton pregnancies with a gestational age (GA ≥38 weeks and without increased risks for respiratory morbidity.MethodsThe incidence of respiratory pathology, unplanned admission, and hypothermia in infants born after FCS in LUMC were retrospectively reviewed and compared with a historical cohort of standard elective cesarean sections (CS.ResultsFrom June 2014 to November 2015, 92 FCS were performed and compared to 71 standard CS in 2013. Incidence of respiratory morbidity, hypothermia, temperatures at arrival at the department, GA, and birth weight were comparable (ns. Unplanned admission occurred more often after FCS when compared to standard CS (21 vs 7%; p = 0.03, probably due to peripheral oxygen saturation (SpO2 monitoring. There was no increase in respiratory pathology (8 vs 6%, ns. One-third of the babies were separated from their mother during or after FCS.ConclusionUnplanned neonatal admissions after elective CS increased after implementing FCS, without an increase in respiratory morbidity or hypothermia. SpO2 monitoring might have a contribution. Separation from the mother occurred often.

    WHO uses the Caesarean section (CS) rate to monitor implementation of emergency obstetric care (EmOC). Although CS rates are rising in sub-Saharan Africa, maternal outcome has not improved. We audited indications for CS and related complications among women with severe maternal morbidity and mortality in a referral hospital in rural Tanzania. Cross-sectional study was from November 2009 to November 2011. Women with severe maternal morbidity and mortality were identified and those with CS were included in this audit. Audit criteria were developed based on the literature review and (inter)national guidelines. Tanzanian and Dutch doctors reviewed hospital notes. The main outcome measured was prevalence of substandard quality of care leading to unnecessary CS and delay in performing interventions to prevent CS. A total of 216 maternal near misses and 32 pregnancy-related deaths were identified, of which 82 (33.1%) had a CS. Indication for CS was in accordance with audit criteria for 36 of 82 (44.0%) cases without delay. In 20 of 82 (24.4%) cases, the indication was correct; however, there was significant delay in providing standard obstetric care. In 16 of 82 (19.5%) cases, the indication for CS was not in accordance with audit criteria. During office hours, CS was more often correctly indicated than outside office hours (60.0% vs. 36.0%, P audit. © 2016 John Wiley & Sons Ltd.

    Full Text Available Background: Low milk production is one of the barries to exclusive breastfeeding. Oxytocin massage is considered as an alternative treatment, which combined with lavender essential oil as an aromatherapy. Objective: This study aims to examine the effect of oxytocin massage using lavender essential oil on the increase of levels of prolactin and milk production in primiparaous mothers after caesarean section. Methods: This was a quasi-experimental study with non-equivalent control group design conducted in October-December 2016 at the General Hospital of Dr.H. Soewondo Kendal. There were 32 recruited by consecutive sampling, divided to be intervention (16 participants and control group (16 participants. Prolactin hormone levels were measured using Enzyme-linked immunosorbent assay (ELIZA, breast milk production was measured based on the indicators of milk volume, urination and defecation frequency and sleep duration of babies; and infant’s weight was also measured by digital scale. Data were analyzed using Mann Whitney and Wilcoxon test. Results: The mean difference of prolactin hormone level in control group was 17.82 ng / ml while mean of difference of hormone prolactin level in intervention group was 132.13 ng / ml. There were statistically significant differences between intervention and control group in prolactin levels (p-value 0.000, milk volume (p-value 0.000, infant weight (p-value 0.000, urination frequency (p-value 0.017, defecation frequency (p-value 0.002, and infant sleep duration (p-value 0.000. Conclusion: There was a significant effect of the oxytocin massage using lavender essential oil on the increase of breast milk production and prolactin levels. Therefore, oxytocin massage using lavender essential oil can be used as an alternative treatment for midwives and other health professionals in an effort to increase milk production in postpartum.

    2017-01-01

    This book presents a broad range of statistical techniques to address emerging needs in the field of repeated measures. It also provides a comprehensive overview of extensions of generalized linear models for the bivariate exponential family of distributions, which represent a new development in analysing repeated measures data. The demand for statistical models for correlated outcomes has grown rapidly recently, mainly due to presence of two types of underlying associations: associations between outcomes, and associations between explanatory variables and outcomes. The book systematically addresses key problems arising in the modelling of repeated measures data, bearing in mind those factors that play a major role in estimating the underlying relationships between covariates and outcome variables for correlated outcome data. In addition, it presents new approaches to addressing current challenges in the field of repeated measures and models based on conditional and joint probabilities. Markov models of first...

    The purpose of this study was to examine the impact of Diagnosis-Related Group (DRG)-based payment on the length of stay and the number of outpatient visits after discharge in for patients who had undergone caesarean section. This study used the health insurance data of the patients in health care facilities that were paid by the Fee-For-Service (FFS) in 2001-2004, but they participated in the DRG payment system in 2005-2007. In order to examine the net effects of DRG payment, the difference-in-differences (DID) method was adopted to observe the difference in health care utilization before and after the participation in the DRG payment system. The dependent variables of the regression model were the length of stay and number of outpatient visits after discharge, and the explanatory variables included the characteristics of the patients and the health care facilities. The length of stay in DRG-paid health care facilities was greater than that in the FFS-paid ones. Yet, DRG payment has no statistically significant effect on the number of outpatient visits after discharge. The results of this study that DRG payment was not effective in reducing the length of stay can be related to the nature of voluntary participation in the DRG system. Only those health care facilities that are already efficient in terms of the length of stay or that can benefit from the DRG payment may decide to participate in the program.

    To audit the quality of obstetric management preceding emergency caesarean sections for prolonged labour. A quality assurance analysis of a retrospective criterion-based audit supplemented by in-depth interviews with hospital staff. Two Tanzanian rural mission hospitals. Audit of 144 cases of women undergoing caesarean sections for prolonged labour; in addition, eight staff members were interviewed. Criteria of realistic best practice were established, and the case files were audited and compared with these. Hospital staff were interviewed about what they felt might be the causes for the audit findings. Prevalence of suboptimal management and themes emerging from an analysis of the transcripts. Suboptimal management was identified in most cases. Non-invasive interventions to potentially avoid operative delivery were inadequately used. When deciding on caesarean section, in 26% of the cases labour was not prolonged, and in 16% the membranes were still intact. Of the women with genuine prolonged labour, caesarean sections were performed with a fully dilated cervix in 36% of the cases. Vacuum extraction was not considered. Amongst the hospital staff interviewed, the awareness of evidence-based guidelines was poor. Word of mouth, personal experience, and fear, especially of HIV transmission, influenced management decisions. The lack of use and awareness of evidence-based guidelines led to misinterpretation of clinical signs, fear of simple interventions, and an excessive rate of emergency caesarean sections. © 2012 The Authors BJOG An International Journal of Obstetrics and Gynaecology © 2012 RCOG.

    Full Text Available Caesarean sections (CS rates continue to increase worldwide without a clear understanding of the main drivers and consequences. The lack of a standardized internationally-accepted classification system to monitor and compare CS rates is one of the barriers to a better understanding of this trend. The Robson's 10-group classification is based on simple obstetrical parameters (parity, previous CS, gestational age, onset of labour, fetal presentation and number of fetuses and does not involve the indication for CS.

    Obstetric surgical site infections (SSIs) are common and expensive to the health care system but remain under reported given shorter postoperative hospital stays and suboptimal post-discharge surveillance systems. SSIs, for the purpose of this paper, are defined according to the Center for Disease Control and Prevention (1999) as infection incurring within 30 days of the operative procedure (in this case, Caesarean section [CS]). Demonstrate the feasibility of real-life use of a patient driven SSIs post-discharge surveillance system consisting of an online database and mobile phone technology (surgical mobile app - how2trak) among women undergoing CS in a Canadian urban centre. Estimate the rate of SSIs and associated predisposing factors. Prospective cohort of consecutive women delivering by CS at one urban Canadian hospital. Using surgical mobile app-how2trak-predetermined demographics, comorbidities, procedure characteristics, and self-reported symptoms and signs of infection were collected and linked to patients' incision self-portraits (photos) on postpartum days 3, 7, 10, and 30. A total of 105 patients were enrolled over a 5-month period. Mean age was 31 years, 13% were diabetic, and most were at low risk of surgical complications. Forty-six percent of surgeries were emergency CSs, and 104/105 received antibiotic prophylaxis. Forty-five percent of patients (47/105) submitted at least one photo, and among those, one surgical site infection was detected by photo appearance and self-reported symptoms by postpartum day 10. The majority of patients whom uploaded photos did so multiple times and 43% of them submitted photos up to day 30. Patients with either a diagnosis of diabetes or self-reported Asian ethnicity were less likely to submit photos. Post-discharge surveillance for CS-related SSIs using surgical mobile app how2trak is feasible and deserves further study in the post-discharge setting. Copyright © 2017. Published by Elsevier Inc.

    Full Text Available Myasthenia gravis is an autoimmune disorder that is characterized by muscle weakness that fluctuates, worsening with exertion, and improving with rest. Diagnosis of myasthenia gravis is made following clinical and physical examination and is confirmed by serum immunoassays to measure autoantibody levels. Myasthenia gravis especially when associated with pregnancy is a high-risk disease, and its course is unpredictable. We described the second report about use of sugammadex after rocuronium for a caesarean delivery with myasthenia gravis, but, unlike our case that formerly was diagnosed with myasthenia gravis, the patient was extubated on postoperative successfully and we did not encounter any respiratory problems. Resumo: Miastenia grave (MG é uma doença autoimune caracterizada por fraqueza muscular que flutua, piorando com o esforço físico e melhorando com o repouso. O diagnóstico de MG é feito após exame clínico e físico e confirmado por imunoensaios séricos para medir os níveis de autoanticorpos. MG, especialmente quando associada à gravidez, é uma doença de alto risco e de curso imprevisível. Descrevemos o segundo relato sobre o uso de sugamadex após rocurônio para um parto cesário com miastenia grave, mas, ao contrário de nosso caso que foi previamente diagnosticado com miastenia grave, a paciente foi extubada com sucesso no pós-operatório sem qualquer problema respiratório.

    Caesarean section (CS) rates are increasing worldwide and maternal request is cited as one of the main reasons for this trend. Women's preferences for route of delivery are influenced by popular media, including magazines. We assessed the information on CS presented in Spanish women's magazines. Systematic review. Women's magazines printed from 1989 to 2009 with the largest national distribution. Articles with any information on CS. Articles were selected, read and abstracted in duplicate. Sources of information, scientific accuracy, comprehensiveness and women's testimonials were objectively extracted using a content analysis form designed for this study. Accuracy, comprehensiveness and sources of information. Most (67%) of the 1223 selected articles presented exclusively personal opinion/birth stories, 12% reported the potential benefits of CS, 26% mentioned the short-term and 10% mentioned the long-term maternal risks, and 6% highlighted the perinatal risks of CS. The most frequent short-term risks were the increased time for maternal recovery (n = 86), frustration/feelings of failure (n = 83) and increased post-surgical pain (n = 71). The most frequently cited long-term risks were uterine rupture (n = 57) and the need for another CS in any subsequent pregnancy (n = 42). Less than 5% of the selected articles reported that CS could increase the risks of infection (n = 53), haemorrhage (n = 31) or placenta praevia/accreta in future pregnancies (n = 6). The sources of information were not reported by 68% of the articles. The portrayal of CS in Spanish women's magazines is not sufficiently comprehensive and does not provide adequate important information to help the readership to understand the real benefits and risks of this route of delivery. © 2014 The Authors.

    Full Text Available Abstract Background Previous studies on change in maternal age composition in Tanzania do not indicate its impact on adverse pregnancy outcomes. We sought to establish temporal changes in maternal age composition and their impact on annual Caesarean section (CS and low birth weight deliveries (LBWT at Muhimbili National Hospital in Tanzania. Methods We conducted data analysis of 91,699 singleton deliveries that took place in the hospital between 1999 and 2005. The data were extracted from the obstetric data base. Annual proportions of individual age groups were calculated and their trends over the years studied. Multiple logistic analyses were conducted to ascertain trends in the risks of CS and LBWT. The impact of age composition changes on CS and LBWT was estimated by calculating annual numbers of these outcomes with and without the major changes in age composition, all others remaining equal. In all statistics, a p value Results The proportion of teenage mothers (12–19 years progressively decreased over time while that of 30–34 years age group increased. From 1999, the risk of Caesarean delivery increased steadily to a maximum in 2005 [adjusted OR = 1.7; 95%CI (1.6–1.8] whereas that of LBWT declined to a minimum in 2005 (adjusted OR = 0.76; 95% CI (0.71–0.82. The current major changes in age trend were responsible for shifts in the number of CS of up to206 cases per year. Likewise, the shift in LBWT was up to 158 cases per year, but the 30–34 years age group had no impact on this. Conclusion The population of mothers giving birth at MNH is progressively becoming older with substantial impact on the incidence of CS and LBWT. Further research is needed to estimate the health cost implications of this change.

    Is first birth Caesarean delivery associated with a lower likelihood of subsequent childbearing when compared with first birth vaginal delivery? In this study of US women whose first delivery was in 2000, those who had a Caesarean delivery were less likely to have a subsequent live birth than those who delivered vaginally. Some studies have reported lower birth rates subsequent to Caesarean delivery in comparison with vaginal delivery, while other studies have reported no difference. We conducted a retrospective cohort study of 52 498 women who had a first singleton live birth in the State of Pennsylvania, USA in 2000 and were followed to the end of 2008 via Pennsylvania birth certificate records to identify subsequent live births during the 8- to 9-year follow-up period. Birth certificate records of first singleton births were linked to the hospital discharge data for each mother and newborn, and linked to all birth certificate records for each mother's subsequent deliveries which occurred in 2000 to the end of 2008. Poisson regression models were used to evaluate the association between first birth factors and whether or not there was a subsequent live birth during the follow-up period. Over an average of 8.5 years of follow-up, 40.2% of women with a Caesarean first birth did not have a subsequent live birth, compared with 33.1% of women with a vaginal first birth (risk ratio (RR): 1.21, 95% confidence interval (CI): 1.18-1.25). Adjustment for the demographic confounders of maternal age, race, education, marital status and health insurance coverage attenuated the RR to 1.16 (95% CI: 1.13-1.19). Specific pregnancy and childbirth-related complications associated with not having a subsequent live birth included diabetes-related disorders, abnormalities of organs and soft tissues of the pelvis, fetal abnormalities, premature or prolonged rupture of membranes, hypertensive disorders, amnionitis, fetal distress and other maternal health problems. However, adjustment

    Visual inspection of cardiotocography traces by obstetricians and midwives is the gold standard for monitoring the wellbeing of the foetus during antenatal care. However, inter- and intra-observer variability is high with only a 30% positive predictive value for the classification of pathological outcomes. This has a significant negative impact on the perinatal foetus and often results in cardio-pulmonary arrest, brain and vital organ damage, cerebral palsy, hearing, visual and cognitive defects and in severe cases, death. This paper shows that using machine learning and foetal heart rate signals provides direct information about the foetal state and helps to filter the subjective opinions of medical practitioners when used as a decision support tool. The primary aim is to provide a proof-of-concept that demonstrates how machine learning can be used to objectively determine when medical intervention, such as caesarean section, is required and help avoid preventable perinatal deaths. This is evidenced using an open dataset that comprises 506 controls (normal virginal deliveries) and 46 cases (caesarean due to pH ≤ 7.20-acidosis, n = 18; pH > 7.20 and pH machine-learning algorithms are trained, and validated, using binary classifier performance measures. The findings show that deep learning classification achieves sensitivity = 94%, specificity = 91%, Area under the curve = 99%, F-score = 100%, and mean square error = 1%. The results demonstrate that machine learning significantly improves the efficiency for the detection of caesarean section and normal vaginal deliveries using foetal heart rate signals compared with obstetrician and midwife predictions and systems reported in previous studies.

    Recent studies in undergraduate medical education have demonstrated the advantage of repeated testing over repeated practice with regard to knowledge and skills retention. The aim of this study was to investigate whether this "testing effect" also applies to skills retention in undergraduate dental education. In this prospective, randomised controlled trial, fourth-year dental students at Göttingen University Medical Centre participated in a training session on surgical suturing in winter term 2014/2015. Following this, they were either assigned to two sessions of additional skills training (group A) or two sessions of skills assessment with feedback (group B). These sessions were spaced over a period of 4 weeks. Skills retention was assessed in a summative objective structured clinical examination (OSCE) at the end of term, that is 6 months after the initial teaching session. A total of 32 students completed the study. With regard to suturing, OSCE performance was significantly better in group B than group A (81.9±13.1% vs 63.0±15.4%; P=0.001; Cohen's d=1.33). There was no significant OSCE performance difference in the two groups with regard to other learning objectives that were addressed in the end-of-term examination. Thus, the group difference was specific to suturing skills. This is the first study to demonstrate that in dental education, repeated testing produces more favourable skills retention than repeated practice. Test-enhanced learning might be a viable concept for skills retention in undergraduate dentistry education. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The Gd5Ge2Si2 alloy and the off-stoichiometric Ni50Mn35In15 Heusler alloy belong to a special class of metallic materials that exhibit first-order magnetostructural transitions near room temperature. The magnetic properties of this class of materials have been extensively studied due to their interesting magnetic behavior and their potential for a number of technological applications such as refrigerants for near-room-temperature magnetic refrigeration. The thermally driven first-order transitions in these materials can be field-induced in the reverse order by applying a strong enough field. The field-induced transitions are typically accompanied by the presence of large magnetic hysteresis, the characteristics of which are a complicated function of temperature, field, and magneto-thermal history. In this study we show that the virgin curve, the major loop, and sequentially measured MH loops are the results of both repeatable and non-repeatable processes, in which the starting magnetostructural state, prior to the cycling of field, plays a major role. Using the Gd5Ge2Si2 and Ni50Mn35In15 alloys, as model materials, we show that a starting single phase state results in fully repeatable processes and large magnetic hysteresis, whereas a mixed phase starting state results in non-repeatable processes and smaller hysteresis.

    The Gd 5 Ge 2 Si 2 alloy and the off-stoichiometric Ni 50 Mn 35 In 15 Heusler alloy belong to a special class of metallic materials that exhibit first-order magnetostructural transitions near room temperature. The magnetic properties of this class of materials have been extensively studied due to their interesting magnetic behavior and their potential for a number of technological applications such as refrigerants for near-room-temperature magnetic refrigeration. The thermally driven first-order transitions in these materials can be field-induced in the reverse order by applying a strong enough field. The field-induced transitions are typically accompanied by the presence of large magnetic hysteresis, the characteristics of which are a complicated function of temperature, field, and magneto-thermal history. In this study we show that the virgin curve, the major loop, and sequentially measured MH loops are the results of both repeatable and non-repeatable processes, in which the starting magnetostructural state, prior to the cycling of field, plays a major role. Using the Gd 5 Ge 2 Si 2 and Ni 50 Mn 35 In 15 alloys, as model materials, we show that a starting single phase state results in fully repeatable processes and large magnetic hysteresis, whereas a mixed phase starting state results in non-repeatable processes and smaller hysteresis

    Full Text Available Conflicting findings on the risk of obesity among subjects born by caesarean section have been published. Caesarean section should also increase the risk of obesity related cardiovascular risk factors if type of delivery is associated with obesity later in life. This study was aimed at assessing the effect of type of delivery on metabolic cardiovascular risk factors in early adulthood.In 1982, maternity hospitals in Pelotas, southern Brazil, were visited and those livebirths whose family lived in the urban area of the city have been followed. In 2000, when male subjects undertook the Army entrance examination (n=2200, fat mass and fat free mass were estimated through bioimpedance. In 2004-2005, we attempted to follow the whole cohort (n=4297, and the following outcomes were studied: blood pressure; HDL cholesterol; triglycerides; random blood glucose, C-reactive protein, waist circumference and body mass index. The estimates were adjusted for the following confounders: family income at birth; maternal schooling; household assets index in childhood; maternal skin color; birth order; maternal age; maternal prepregnancy weight; maternal height; maternal smoking during pregnancy; birthweight and family income at early adulthood.In the crude analyses, blood pressure (systolic, diastolic and mean arterial pressure and body mass index were higher among subjects who were delivered through caesarean section. After controlling for confounders, systolic blood pressure was 1.15 mmHg (95% confidence interval: 0.05; 2.25 higher among subjects delivered by caesarean section, and BMI 0.40 kg/m(2 (95% confidence interval: 0.08; 0.71. After controlling for BMI the effect on systolic blood pressure dropped to 0.60 mmHg (95% confidence interval: -0.47; 1.67. Fat mass at 18 years of age was also higher among subjects born by caesarean section.Caesarean section was associated with a small increased in systolic blood pressure, body mass index and fat mass.

    Aim: To report experience of prophylactic occlusion balloon catheters (POBCs) in both internal iliac arteries before caesarean section, with or without embolization, to preserve the uterus and reduce haemorrhage. Methods and materials: Twenty-seven women diagnosed with morbidly adherent placenta (MAP) and with suspected placenta percreta underwent POBC placement before caesarean section. The balloons were inflated immediately after delivery of the baby. The patients' case notes were reviewed retrospectively for histological grading of MAP, blood loss, transfusion, requirement of uterine artery embolization (UAE), or hysterectomy, radiation dose, and infant or maternal morbidity and mortality. Results: MAP was confirmed histologically as percreta in 17, accreta in eight, and increta in two women. Mean blood loss was 1.92 l (range 0.5–12 l). Postpartum haemorrhage (PPH) occurred in nine patients. Eight were referred for UAE, which was successful in six. Immediate peri-partum hysterectomy was performed in one patient. Three women in total required hysterectomy, two after recurrent haemorrhage after UAE. No foetal morbidity or mortality occurred. No maternal mortality occurred. There was one case of iliac artery thrombosis, which resolved with conservative therapy. Conclusion: POBC, with or without UAE, contributes to reduction of blood loss and preservation of the uterus in women with MAP. - Highlights: • Management of morbidly adherent placenta requires a multidisciplinary team approach. • Prophylactic occlusion balloon catheters reduce blood loss and help avoid hysterectomy. • Protocols ensure correct management of placenta percreta patients and minimise risk

    Objective Rural north-central Liberia has one of the world's highest maternal mortality ratios. We studied health facility birthing service utilisation and the motives of women seeking or not seeking facility-based care in north-central Liberia. Design Cross-sectional community-based structured interviews and health facility medical record review. Setting A regional hospital and the surrounding communities in rural north-central Liberia. Participants A convenience sample of 307 women between 15 and 49 years participated in structured interviews. 1031 deliveries performed in the regional hospital were included in the record review. Primary outcomes Delivery within a health facility and caesarean delivery rates were used as indicators of direct utilisation of care and as markers of availability of maternal health services. Results Of 280 interview respondents with a prior childbirth, only 47 (16.8%) delivered their last child in a health facility. Women who did not use formal services cited cost, sudden labour and family tradition or religion as their principal reasons for home delivery. At the regional hospital, the caesarean delivery rate was 35.5%. Conclusions There is an enormous unmet need for maternal health services in north-central Liberia. Greater outreach and referral services as well as community-based education among women, family members and traditional midwives are vital to improve the timely utilisation of care. PMID:23117566

    The aim of this study was to investigate caesarean operation (CO) undertaken before the pre-partum decrease of progesterone but following administration of a progesterone receptor antagonist and to evaluate the innocuity of this procedure for the dam and pups. Thirty seven bitches of 15 different breeds, received an injection of 15 mg/kg aglepristone 59 or 60 days after the estimated day of ovulation, determined by progesterone quantitative assays, and caesarean section (CS) was performed between 20 and 24 h after administration. Progesterone remained above 6 nmol/l at the time of CS (mean = 15.75, SD = 3.84). No post-operative clinical complications were reported in any of the bitches. All bitches were able to nurse and feed their puppies in the first 24 h following surgery. No pups showed any signs of prematurity and 5 out of 188 pups (2.6) died in the first 2 weeks after delivery. This small study demonstrates that a CS may be safely and successfully performed an average of 2 days before the expected date of parturition following the administration of aglepristone, without any harmful consequence for the dam and her neonates.

    To analyze the impact of caesarean section (CS) on fertility and time to pregnancy in German gynecological practices. Women initially diagnosed for the first time with a vaginal delivery (VD) or CS between 2000 and 2013 were identified by 227 gynecologists in the IMS Disease Analyzer database. They were included if they were aged between 16 and 40 years, and were not previously diagnosed with female sterility. The two main outcomes were the first-time diagnosis of female sterility and the time between the first delivery and the next pregnancy within 10 years. A multivariate Cox regression model was used to predict these outcomes on the basis of patient characteristics. 6483 patients were included in the CS group and 6483 in the VD group. Mean age was 30.6 years and the proportion of individuals with private health insurance amounted to 9.0 %. Within 10 years of the index date, 19.5 % of women who delivered by CS and 18.3 % of women who delivered vaginally were diagnosed with sterility (p value = 0.0148). CS and polycystic ovary syndrome significantly increased the risk of sterility. Within 10 years of the index date, 57.9 % of women who underwent a CS and 64.0 % of women who delivered vaginally were pregnant for the second time (p value <0.001). CS, polycystic ovary syndrome, and the deterioration of menstrual cycle significantly decreased the chance of becoming pregnant a second time. CS is associated with an increased risk of sterility and a decreased number of subsequent pregnancies in Germany.

    2015-01-01

    Motivated by online advertising auctions, we consider repeated Vickrey auctions where goods of unknown value are sold sequentially and bidders only learn (potentially noisy) information about a good's value once it is purchased. We adopt an online learning approach with bandit feedback to model this problem and derive bidding strategies for two models: stochastic and adversarial. In the stochastic model, the observed values of the goods are random variables centered around the true value of t...

    To determine the economic impact of the introduction of carbetocin for the prevention of postpartum haemorrhage (PPH) at caesarean section, compared to oxytocin. The model is a decision tree conducted from a UK National Health Service perspective. 1500 caesarean sections (both elective and emergency) were modelled over a 12 month period. Efficacy data was taken from a published Cochrane meta-analysis, and costs from NHS Reference costs, the British National Formulary and the NHS electronic Medicines Information Tool. A combination of hospital audit data and expert input from an advisory board of clinicians was used to inform resource use estimates. The main outcome measures were the incidence of PPH and total cost over a one year time horizon, as a result of using carbetocin compared to oxytocin for prevention of PPH at caesarean section. The use of carbetocin compared to oxytocin for prevention of PPH at caesarean section was associated with a reduction of 30 (88 vs 58) PPH events (>500ml blood loss), and a cost saving of £27,518. In probabilistic sensitivity analysis, carbetocin had a 91.5% probability of producing better outcomes, and a 69.4% chance of being dominant (both cheaper and more effective) compared to oxytocin. At list price, the introduction of carbetocin appears to provide improved clinical outcomes along with cost savings, though this is subject to uncertainty regarding the underlying data in efficacy, resource use, and cost.

    Fast radio bursts are millisecond-duration astronomical radio pulses of unknown physical origin that appear to come from extragalactic distances. Previous follow-up observations have failed to find additional bursts at the same dispersion measure (that is, the integrated column density of free electrons between source and telescope) and sky position as the original detections. The apparent non-repeating nature of these bursts has led to the suggestion that they originate in cataclysmic events. Here we report observations of ten additional bursts from the direction of the fast radio burst FRB 121102. These bursts have dispersion measures and sky positions consistent with the original burst. This unambiguously identifies FRB 121102 as repeating and demonstrates that its source survives the energetic events that cause the bursts. Additionally, the bursts from FRB 121102 show a wide range of spectral shapes that appear to be predominantly intrinsic to the source and which vary on timescales of minutes or less. Although there may be multiple physical origins for the population of fast radio bursts, these repeat bursts with high dispersion measure and variable spectra specifically seen from the direction of FRB 121102 support an origin in a young, highly magnetized, extragalactic neutron star.

    The accepted rate rate of caesarean section is 15%. It is expected that an increase in the density of midwives in the family physician program lead to a decrease in this indicator. This study aimed to compare the rates of caesarean section and women's awareness and preference for mode of delivery before and after the implementation of the family physician program in health centres with and without an increase in midwives density. In this cross-sectional study, using multistage cluster sampling method a total of 668 mothers with two-month-old children were selected from among all mothers with two-month-old children who were living in rural areas of Kurdistan province. Using the difference-in-differences model and Matchit statistical model, the factors associated with caesarean section rates and women's awareness and preference for mode of delivery were compared in centres with and without an increase in midwives density after the implementation of the family physician program. To compare the changes before and after the program, we used the data collected from the same number of women in 2005 as the baseline. After adjusting for baseline data collected in 2005, the resutls showed no significant change in caesarean section rates and women's awareness and preference for mode of delivery in the centres with and without an increase in midwives density after the implementation of the family physician program. The Matchit model showed a significant mean increase 14%(0.03-0.25) in women's awareness of the benefits of natural childbirth between 2005 and 2013 in health centres where the density of midwives increased compared with health centres where it did not. The difference-in-differences model showed that the odds ratio of women's preference for caesarean section decreased by 41% among participants who were aware of the benefits of natural childbirth, (OR = 0.59, 95% CI: (0.22-0.85); P>0.001). The results of this study showed that an increase in the density of midwives

    Aim: To determine the efficacy and safety of caesarean section combined with temporary aortic balloon occlusion followed by uterine artery embolisation (UAE) for the treatment of patients with placenta accreta. Materials and methods: This retrospective study involved 42 patients with placenta accreta. All patients underwent caesarean section combined with temporary aortic balloon occlusion followed by UAE through the right femoral approach. Results: All patients were confirmed to have placenta praevia and accreta, including five patients with placenta percreta, at the time of delivery. The technical success rate of the combined treatment was 97.6% (41/42). Forty-one patients underwent successful caesarean section with conservation of the uterus. Hysterectomy was required in one (3.1%) patient. The amount of blood loss and blood transfusion, and the operation time were was 586 ± 355 ml, 422 ± 83 ml and 65.5 ± 10.6 minutes, respectively. The mean postoperative hospital stay, occlusion time and fetal radiation dose were 5.5 ± 2.6 days, 22.4 ± 7.2 minutes and 4.2 ± 2.9 mGy, respectively. There were no significant changes before and 7 days after the endovascular procedure in creatinine levels (56.8 ± 13.8 μmol/l versus 63.4 ± 16.7 μmol/l, p = 0.09) or urea nitrogen (6.3 ± 2.5 μmol/l versus 7.4 ± 3.8 μmol/l, p = 0.17). There were no access-site complications after the endovascular procedure and no complications related to the intervention during follow-up. Conclusion: Temporary aortic balloon occlusion followed by UAE can effectively control postpartum haemorrhage during placental dissection, and reduce transfusion requirements, hysterectomy rate, and operation time in patients with placenta accreta. -- Highlights: •Aortic balloon occlusion can overcome the collateral flow from other arteries. •UAE can effectively manage secondary postpartum haemorrhage. •The aortic balloon can rapidly and easily insert. •The mean

    Tooth injuries are serious clinical conditions. Some children experience dental trauma only once, while others are more prone to repeated tooth injuries. Repeated dental trauma occurs in 19.4% to 30% of patients. Pain and dental trauma are the most common reasons for fear and anxiety. The main objective of this study was to investigate how dental trauma, as well as repeated dental trauma affects the occurrence and development of dental fear in children. The study was conducted on a random sample of 147 subjects (88 boys and 59 girls) aged 5-8 and 9-12 years. Subjects in both age groups were divided into subroups without dental trauma, with one dental trauma and with repeated dental trauma. The validated Children’s Fear Survey Schedule – Dental Subscale was used on fear assessment. Results showed that only 12.2% of children without trauma, 33.3% with one trauma and 51.7% with repeated trauma were not afraid of injection. Older children had a significantly lower fear of injections, touch of an unknown person, choking, going to the hospital and people in white uniforms. Dentist was not the cause of fear in 65.5% of patients with repeated trauma. With each repeated injury of teeth, the degree of their fear of dental treatment was lower.

    Patient-initiated elective Caesarean section (PIECS) is increasingly prevalent and is emerging as an urgent issue for individual maternity practitioners, hospitals, and policy makers, as well as for maternity patients. This qualitative study sought to explore women's experiences of the decision-making process leading to elective operative delivery without medical indication. We conducted 17 exploratory qualitative in-depth interviews with primiparous women who had undergone a patient-initiated elective Caesarean section in the absence of any medical indication. The study took place in five hospitals (three urban, two semi-rural) in British Columbia. The findings revealed three themes within the process of women deciding to have a Caesarean section: the reasons for their decision, the qualities of the decision-making process, and the social context in which the decision was made. The factors that influenced a patient-initiated request for delivery by Caesarean section in participants in this study were diverse, culturally dependent, and reflective of varying degrees of emotional and evidence-based influences. PIECS is a rare but socially significant phenomenon. The a priori decision making of some women choosing PIECS does not follow the usual diagnosis-intervention trajectory, and the care provider may have to work in reverse to ensure that the patient fully understands the risks and benefits of her decision subsequent to the decision having been made, while still ensuring patient autonomy. Results from this study provide a context for a woman's request for an elective Caesarean section without medical indication, which may contribute to a more efficacious informed consent process.

    A rising caesarean section rate and substandard peri-operative care are believed to be the main reasons for recent increases in maternal deaths from bleeding during and after caesarean section (BDACS) in South Africa (SA). The Donabedian model assumes that clinical outcomes are influenced by healthcare workers and the healthcare system. To evaluate near-miss cases from BDACS with regard to health system structure (resources and facilities) and process (patient care). A cross-sectional prospective study was conducted in greater Johannesburg, SA. Data of women who had near-miss-related BDACS were collected by means of ongoing surveillance at 13 public hospitals. The World Health Organization intervention criteria were used to identify near-miss cases. A comparison of structure and process between the healthcare facilities was conducted. Of 20 527 caesarean sections , there were 93 near misses and 7 maternal deaths from BDACS. Dominant risk factors for near misses were previous caesarean section (43.9%), anaemia (25.3%) and pregnancy-induced hypertension (28.6%). Eighteen women were transferred to higher levels of care, and 8 (44.4%) experienced transport delays of >1 hour. The caesarean section decision-to-incision interval (DII) was ≥60 minutes in 77 of 86 women, with an average interval of 4 hours. Structural deficiencies were frequently present in district hospitals, and there were serious delays in ambulance transfer and DIIs at all levels of care. The majority of the women had risk factors for BDACS. There were major ambulance delays and lack of facilities, mostly in district hospitals. All women required life-saving interventions, but could not access appropriate care timeously. Prevention and management of BDACS require a fully functional health system.

    Full Text Available Objectives: This study aimed to evaluate rates of success and perinatal complications of labour induction using an intracervical Foley catheter among women with a previous Caesarean delivery at a tertiary centre in Oman. Methods: This retrospective cohort study included 68 pregnant women with a history of a previous Caesarean section who were admitted for induction via Foley catheter between January 2011 and December 2013 to the Sultan Qaboos University Hospital, Muscat, Oman. Patient data were collected from electronic and delivery ward records. Results: Most women were 25–35 years old (76.5% and 20 women had had one previous vaginal delivery (29.4%. The most common indication for induction of labour was intrauterine growth restriction with oligohydramnios (27.9%. Most women delivered after 40 gestational weeks (48.5% and there were no neonatal admissions or complications. The majority experienced no complications during the induction period (85.3%, although a few had vaginal bleeding (5.9%, intrapartum fever (4.4%, rupture of the membranes (2.9% and cord prolapse shortly after insertion of the Foley catheter (1.5%. However, no cases of uterine rupture or scar dehiscence were noted. Overall, the success rate of vaginal birth after a previous Caesarean delivery was 69.1%, with the remaining patients undergoing an emergency Caesarean section (30.9%. Conclusion: The use of a Foley catheter in the induction of labour in women with a previous Caesarean delivery appears a safe option with a good success rate and few maternal and fetal complications.

    Time lapse (4-D) seismic is a promising tool for reservoir characterization and monitoring. The method is apparently simple: to acquire data repeatedly over the same reservoir, process and interpret the data sets, then changes between the data sets indicate changes in the reservoir. A problem with time lapse seismic data is that reservoirs are a relatively small part of the earth and important reservoir changes may cause very small differences to the time lapse data. The challenge is to acquire and process economical time lapse data such that reservoir changes can be detected above the noise of varying acquisition and environment. 7 refs., 9 figs.

  4. Telomerase Repeated Amplification Protocol (TRAP).

    Science.gov (United States)

    Mender, Ilgen; Shay, Jerry W

    2015-11-20

    Telomeres are found at the end of eukaryotic linear chromosomes, and proteins that bind to telomeres protect DNA from being recognized as double-strand breaks thus preventing end-to-end fusions (Griffith et al. , 1999). However, due to the end replication problem and other factors such as oxidative damage, the limited life span of cultured cells (Hayflick limit) results in progressive shortening of these protective structures (Hayflick and Moorhead, 1961; Olovnikov, 1973). The ribonucleoprotein enzyme complex telomerase-consisting of a protein catalytic component hTERT and a functional RNA component hTR or hTERC - counteracts telomere shortening by adding telomeric repeats to the end of chromosomes in ~90% of primary human tumors and in some transiently proliferating stem-like cells (Shay and Wright, 1996; Shay and Wright, 2001). This results in continuous proliferation of cells which is a hallmark of cancer. Therefore, telomere biology has a central role in aging, cancer progression/metastasis as well as targeted cancer therapies. There are commonly used methods in telomere biology such as Telomere Restriction Fragment (TRF) (Mender and Shay, 2015b), Telomere Repeat Amplification Protocol (TRAP) and Telomere dysfunction Induced Foci (TIF) analysis (Mender and Shay, 2015a). In this detailed protocol we describe Telomere Repeat Amplification Protocol (TRAP). The TRAP assay is a popular method to determine telomerase activity in mammalian cells and tissue samples (Kim et al. , 1994). The TRAP assay includes three steps: extension, amplification, and detection of telomerase products. In the extension step, telomeric repeats are added to the telomerase substrate (which is actually a non telomeric oligonucleotide, TS) by telomerase. In the amplification step, the extension products are amplified by the polymerase chain reaction (PCR) using specific primers (TS upstream primer and ACX downstream primer) and in the detection step, the presence or absence of telomerase is

    We develop a coordinated hybrid automatic repeat request (HARQ) approach. With the proposed scheme, if a user message is correctly decoded in the first HARQ rounds, its spectrum is allocated to other users, to improve the network outage probability and the users\\' fairness. The results, which are obtained for single- and multiple-antenna setups, demonstrate the efficiency of the proposed approach in different conditions. For instance, with a maximum of M retransmissions and single transmit/receive antennas, the diversity gain of a user increases from M to (J+1)(M-1)+1 where J is the number of users helping that user.

    Postpartum haemorrhage is a major cause of maternal morbidity and mortality worldwide. A recent Cochrane review of carbetocin (long-acting oxytocin analogue) concluded that its use decreased additional uterotonic requirements, however, no included studies compared its use against intravenous bolus oxytocin. The majority of studies of carbetocin have considered its use in vaginal delivery; no studies have examined the economic implications of its use. This study describes a clinical and financial evaluation undertaken at a United Kingdom District General Hospital surrounding the introduction of carbetocin for prophylaxis against postpartum haemorrhage at caesarean deliveries. A range of clinical outcomes were observed including frequency of postpartum haemorrhage, estimated blood loss, transfusion requirements, change in haemoglobin or haemodynamics, use of additional uterotonics and perioperative recovery. Finally, a composite financial analysis was performed. No clinically significant benefit was found, however associated costs increased by £18.52/patient.

    During a 5-year period there were 32 cases where the vaginal assessment performed by a specialist registrar in the second stage of labour was re-assessed within 15 minutes by a consultant obstetrician. The examination was prompted by a request for permission to perform a caesarean section in the second stage of labour. The results suggest a significant discrepancy between the consultants and the specialist registrar's findings, with 44% of the cases indicating a difference in the position of the head, and 81% a difference in the station of the head. No comment was made about caput or moulding in the majority of cases (94%). The study findings suggest that vaginal examination, like instrumental delivery, is a skill that is being eroded and will require formal instruction to address this problem.

  8. A Quality Improvement Approach to Reducing the Caesarean section Surgical Site Infection Rate in a Regional Hospital

    Surgical site infection (SSI) rates are used extensively by hospitals as a basis for quality improvement. A 30-day post-discharge SSI programme for Caesarean section operations has been implemented in Our Lady of Lourdes Hospital since 2011. It has been shown that skin antisepsis and antibiotic prophylaxis are key factors in the prevention of SSI. Using quality improvement methodology, an infection prevention bundle was introduced to address these two factors. Skin antisepsis was changed from povidone-iodine to chlorhexidine-alcohol. Compliance with choice of antibiotic prophylaxis increased from 89.6% in 2014 to 98.5% in 2015. Compliance with timing also improved. The SSI rate of 7.5% was the lowest recorded to date, with the majority of SSIs (64%) diagnosed after hospital discharge. The level of variation was also reduced. However, the continued presence of variation and possibility of lower infection rates from the literature imply that further improvements are required.

    Postpartum haemorrhage (PPH) is the leading cause of maternal mortality worldwide. Prophylaxis with oxytocic medication is recommended by the WHO to prevent its occurrence. Carbetocin is a newer oxytocic, with potential to lower PPH rates, reduce the total use of oxytocic drugs and lead to financial savings. Meta-analyses have confirmed a reduction in the use of additional oxytocic medication with the use of carbetocin compared to oxytocin. However, there are few studies evaluating the costs of carbetocin prophylaxis. We carried out a prospective cohort study evaluating the financial impact of carbetocin, following its introduction at our centre for caesarean section. We collected data for 400 patients in total, making this, to our knowledge, the largest study conducted on this topic. We found a significant reduction in PPH rates and the use of additional oxytocics with projected overall financial savings of £68.93 per patient with the use of carbetocin. Impact statement It is well established that carbetocin reduces the use of secondary oxytocics compared to oxytocin alone in the active management of the third stage of labour. Evidence for reduction of post-partum haemorrhage and its cost effectiveness are more equivocal. Our study demonstrates that carbetocin also reduces post-partum haemorrhage, use of blood and blood products and midwifery recovery time in the setting of caesarean section. We have also demonstrated that despite the increased index cost of carbetocin it delivers an overall substantial cost benefit. The implications of these findings are of reduced morbidity, faster recovery and cost savings in these times of austerity in the UK. It allows more efficient labour distribution of midwives, particularly in the setting of staff shortages across the NHS. A randomised control trial in this area needs to be conducted to determine the cost benefit of carbetocin and with this and post-partum haemorrhage rates as the primary outcome measures.

    Full Text Available Background : The present audit was initiated to evaluate the knowledge, attitude, perception and acceptance of women toward labor analgesia and caesarean section, in a Medical College Hospital in Udaipur, India. Materials and Methods : A semi-structured interview of 200 antenatal women was conducted, to assess the knowledge, attitude and perception regarding labor analgesia and caesarean section (CS and to estimate the correlation of awareness and acceptability with demographic variables. The data were analyzed using Epi Info 6 and the Likert type scale (0 - 10, as also the chi square test, to calculate the statistical significance. Results : Most of the patients (n = 181, 90.50% were unaware of labor analgesia. When the option of labor analgesia was offered, only 23% (n = 46 accepted it and the most significant reason for refusal was to experience natural child birth (n = 114 / 154, 74.03%. An educational status of the graduate level had a positive impact on knowledge about labor analgesia (P = 0.0001. When the option for CS was offered, 73.50% women (n = 147; P = 0.008 refused and the most common reasons for refusal were fear of operation (53.06%, n = 78 and delay in resuming household work (46.26%, n = 68. Educational status up to the graduate level and previous surgical experience of CS had a positive correlation with preference for CS (P = 0.0092 and P = 0.0001, respectively. Conclusions : Awareness and acceptance for labor analgesia was relatively low among the prospective parturients. A higher level of education had a significant impact on their decisions regarding delivery.

    Full Text Available Abstract Background Increasing rates of postpartum haemorrhage in developed countries over the past two decades are not explained by corresponding changes in risk factors and conjecture has been raised that maternal obesity may be responsible. Few studies investigating risk factors for PPH have included BMI or investigated PPH risk among nulliparous women. The aim of this study was to determine in a cohort of nulliparous women delivering at term whether overweight and obesity are independent risk factors for major postpartum haemorrhage (PPH ≥1000ml after vaginal and caesarean section delivery. Methods The study population was nulliparous singleton pregnancies delivered at term at National Women’s Hospital, Auckland, New Zealand from 2006 to 2009 (N=11,363. Multivariable logistic regression was adjusted for risk factors for major PPH. Results There were 7238 (63.7% women of normal BMI, 2631 (23.2% overweight and 1494 (13.1% obese. Overall, PPH rates were increased in overweight and obese compared with normal-weight women (n=255 [9.7%], n=233 [15.6%], n=524 [7.2%], p Conclusion Nulliparous obese women have a twofold increase in risk of major PPH compared to women with normal BMI regardless of mode of delivery. Higher rates of PPH among obese women are not attributable to their higher rates of caesarean delivery. Obesity is an important high risk factor for PPH, and the risk following vaginal delivery is emphasised. We recommend in addition to standard practice of active management of third stage of labour, there should be increased vigilance and preparation for PPH management in obese women.

    2009-01-01

    Full Text Available To address whether there are differences of variation among repeat motif types and among taxonomic groups, we present here an analysis of variation and correlation of dinucleotide microsatellite repeats in eukaryotic genomes. Ten taxonomic groups were compared, those being primates, mammalia (excluding primates and rodentia, rodentia, birds, fish, amphibians and reptiles, insects, molluscs, plants and fungi, respectively. The data used in the analysis is from the literature published in the Journal of Molecular Ecology Notes. Analysis of variation reveals that there are no significant differences between AC and AG repeat motif types. Moreover, the number of alleles correlates positively with the copy number in both AG and AC repeats. Similar conclusions can be obtained from each taxonomic group. These results strongly suggest that the increase of SSR variation is almost linear with the increase of the copy number of each repeat motif. As well, the results suggest that the variability of SSR in the genomes of low-ranking species seem to be more than that of high-ranking species, excluding primates and fungi.

    Full Text Available The last Hungarian repeat station survey was completed between October 2010 and February 2011. Declination, inclination and the total field were observed using one-axial DMI fluxgate magnetometer mounted on Zeiss20A theodolite and GSM 19 Overhauser magnetometer. The magnetic elements of the sites were reduced to the epoch of 2010.5 on the basis of the continuous recordings of Tihany Geophysical Observatory. In stations located far from the reference observatory, the observations were carried out in the morning and afternoon in order to decrease the effect of the distant temporal correction. To further increase the accuracy, on-site dIdD variometer has also been installed near the Aggtelek station, in the Baradla cave, during the survey of the easternmost sites. The paper presents the technical details and the results of our last campaign. The improvement of the accuracy of the temporal reduction by the use of the local variometer is also reported.

    A cart system using linear synchronous motors was being considered for the Plutonium Immobilization Plant (PIP). One of the applications in the PIP was the movement of a stack of furnace trays, filled with the waste form (pucks) from a stacking/unstacking station to several bottom loaded furnaces. A system was ordered to perform this function in the PIP Ceramic Prototype Test Facility (CPTF). This system was installed and started up in SRTC prior to being installed in the CPTF. The PIP was suspended and then canceled after the linear synchronous motor system was started up. This system was used to determine repeatability of a linear synchronous motor cart system for the Modern Pit Facility

    The endeavor to develop quantum networks gave rise to a rapidly developing field with far-reaching applications such as secure communication and the realization of distributed computing tasks. This ultimately calls for the creation of flexible multiuser structures that allow for quantum communication between arbitrary pairs of parties in the network and facilitate also multiuser applications. To address this challenge, we propose a two-dimensional quantum repeater architecture to establish long-distance entanglement shared between multiple communication partners in the presence of channel noise and imperfect local control operations. The scheme is based on the creation of self-similar multiqubit entanglement structures at growing scale, where variants of entanglement swapping and multiparty entanglement purification are combined to create high-fidelity entangled states. We show how such networks can be implemented using trapped ions in cavities.

    Fibre reinforced concretes (FRC) containing several volume fractions in different ratios of two types of fibres - polypropylene and steel, were tested under repeated loading. Mechanical properties of specimens - cubes 150/150/150 mm (for compressive strength), prisms 100/100/400 (for flexural strength), short cylinders 150/60 mm (for impact strength) have been experimentally investigated before and after cyclic loading at the age of 28 days curing time. Mix proportions were designed after DIN 1045 with max. aggregate size 8 mm and grading curve B 8. Portland Cement PC 400 in the amount of 450 kg. m -3 was applied and W/C ratio 0.55. Workability of mixes was measured by Vebe method and regulated by plasticizing admixture Ligoplast Na. Maximum hybrid fibre volume fraction (polypropylene + steel) was 1.0%. Dynamic forces generated in Schenck testing machine with frequency 16 Hz had sinusoidal wave form varying between 0.7 and 0.1 of static mechanical characteristics. The number of cycles in all tests was 10 5 . The residual MOR at static four point bending test and working diagram force-deflection was carried out as well. The impact properties after repeated loading in compression were tested by means of falling weight test. Relationships between composition of fibre composites with different combination of polypropylene (0.2, 0.3, 0.5% by volume) and steel (0.5, 0.7, and 0.8% by volume) fibre content were obtained and technological properties of mixes as well.

    Full Text Available Most of the debate ¡s about how the slow or frequent turnover of fresh fat affects the deterioration, of fat used in frying. Then, the modification of different oils used in repeated fryings of potatoes without or with turnover of fresh oil, under similar frying conditions, was evaluated by two criteria: by measuring the total polar component isolated by column chromatography and by the evaluation of the specific compounds related to thermoxidative and hydrolytic alteration by High Performance Size Exclusion Chromatography (HPSEC. The results indicate that with frequent turnover of fresh oil, the critical level of 25% of polar material is rarely reached, and there are fewer problems with fat deterioration because the frying tended to increase the level of polar material and thermoxidative compounds (polymers and dimers of triglycerides and oxidized triglycerides in the fryer oil during the first fryings, followed by minor changes and a tendency to reach a near-steady state in successive fryings. However, in repeated frying of potatoes using a null turnover the alteration rate was higher being linear the relationship found between polar material or the different thermoxidative compounds and the number of fryings. On the other hand chemical reactions produced during deep-fat frying can be minimized by using proper oils. In addition the increased level of consumers awareness toward fat composition and its impact on human health could had an impact on the selection of fats for snacks and for industry. In this way monoenic fats are the most adequate from a nutritional point of view and for its oxidative stability during frying.

    The effects of repeated swim stress on brain benzodiazepine receptors were examined in the mouse using both an in vivo and in vitro binding method. Specific in vivo binding of [ 3 H]Ro15-1788 to benzodiazepine receptors was decreased in the hippocampus, cerebral cortex, hypothalamus, midbrain and striatum after repeated swim stress (7 consecutive days of daily swim stress) when compared to nonstressed mice. In vivo benzodiazepine receptor binding was unaltered after repeated swim stress in the cerebellum and pons medulla. The stress-induced reduction in in vivo benzodiazepine receptor binding did not appear to be due to altered cerebral blood flow or to an alteration in benzodiazepine metabolism or biodistribution because there was no difference in [14C]iodoantipyrine distribution or whole brain concentrations of clonazepam after repeated swim stress. Saturation binding experiments revealed a change in both apparent maximal binding capacity and affinity after repeated swim stress. Moreover, a reduction in clonazepam's anticonvulsant potency was also observed after repeated swim stress [an increase in the ED50 dose for protection against pentylenetetrazol-induced seizures], although there was no difference in pentylenetetrazol-induced seizure threshold between the two groups. In contrast to the results obtained in vivo, no change in benzodiazepine receptor binding kinetics was observed using the in vitro binding method. These data suggest that environmental stress can alter the binding parameters of the benzodiazepine receptor and that the in vivo and in vitro binding methods can yield substantially different results

    To illustrate the variability in the use of antibiotic prophylaxis for caesarean section, and its effect on the prevention of postoperative infections. Secondary analysis of a cross-sectional study. Twenty-nine countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health. Three hundred and fifty-nine health facilities with the capacity to perform caesarean section. Descriptive analysis and effect estimates using multilevel logistic regression. Coverage of antibiotic prophylaxis for caesarean section. A total of 89 121 caesarean sections were performed in 332 of the 359 facilities included in the survey; 87% under prophylactic antibiotic coverage. Thirty five facilities provided 0-49% coverage and 77 facilities provided 50-89% coverage. Institutional coverage of prophylactic antibiotics varied greatly within most countries, and was related to guideline use and the practice of clinical audits, but not to the size, location of the institution or development index of the country. Mothers with complications, such as HIV infection, anaemia, or pre-eclampsia/eclampsia, were more likely to receive antibiotic prophylaxis. At the same time, mothers undergoing caesarean birth prior to labour and those with indication for scheduled deliveries were also more likely to receive antibiotic prophylaxis, despite their lower risk of infection, compared with mothers undergoing emergency caesarean section. Coverage of antibiotic prophylaxis for caesarean birth may be related to the perception of the importance of guidelines and clinical audits in the facility. There may also be a tendency to use antibiotics when caesarean section has been scheduled and antibiotic prophylaxis is already included in the routine clinical protocol. This study may act as a signal to re-evaluate institutional practices as a way to identify areas where improvement is possible. © 2014 RCOG The World Health Organization retains copyright and all other rights in

    Cognitive aids have come to be viewed as promising tools in the management of perioperative critical events. The majority of published simulation studies have focussed on perioperative crises that are characterised by time pressure, rare occurrence, or complex management steps (e.g., cardiac arrest emergencies, management of the difficult airway). At present, there is limited information on the usefulness of cognitive aids in critical situations with moderate time pressure and complexity. Intraoperative myocardial infarction may be an emergency to which these limitations apply. Anaesthetic teams were allocated to control (no cognitive aid; n = 10) or intervention (cognitive aid provided; n = 10) groups. The primary aim of this study was to compare cognitive aid versus memory for intraoperative ST-elevation myocardial infarction (STEMI) management in a simulation of caesarean delivery under spinal anaesthesia. We identified nine evidence-based metrics of essential care from current guidelines and subdivided them into mandatory (high level of evidence; no interference with surgery) and optional (lower class of recommendation; possible impact on surgery) tasks. Six clinically relevant tasks were added by consensus. Implementation of these steps was measured by scoring task items in a binary fashion (yes/no). The interval between the diagnosis of STEMI and the first contact with the cardiac catheterisation lab was measured. To determine whether or not the cognitive aid had prompted an action, participants from the cognitive aid group were interviewed during debriefing on every single treatment step. At the end of the simulation, session participants were asked to complete a survey. The presence of the cognitive aid did not shorten the time interval until the cardiac catheterisation lab was contacted. The availability of the cognitive aid improved task performance in the tasks identified from the guidelines (93% vs. 69%; p consultants and nurses. The

    Doxapram is a respiratory stimulant used to treat hypoventilation. Here we investigated whether doxapram could also trigger respiratory neuroplasticity. Specifically, we hypothesized that intermittent delivery of doxapram at low doses would lead to long-lasting increases (i.e., facilitation) of phrenic motor output in anesthetized, vagotomized, and mechanically-ventilated rats. Doxapram was delivered intravenously in a single bolus (2 or 6mg/kg) or as a series of 3 injections (2mg/kg) at 5min intervals. Control groups received pH-matched saline injections (vehicle) or no treatment (anesthesia time control). Doxapram evoked an immediate increase in phrenic output in all groups, but a persistent increase in burst amplitude only occurred after repeated dosing with 2mg/kg. At 60min following the last injection, phrenic burst amplitude was 168±24% of baseline (%BL) in the group receiving 3 injections (Pphrenic response to doxapram (2mg/kg) was reduced by 68% suggesting that at low doses the drug was acting primarily via the carotid chemoreceptors. We conclude that intermittent application of doxapram can trigger phrenic neuroplasticity, and this approach might be of use in the context of respiratory rehabilitation following neurologic injury. © 2013.

    2008-08-01

    The leucine-rich repeat is a widespread structural motif of 20-30 amino acids with a characteristic repetitive sequence pattern rich in leucines. Leucine-rich repeat domains are built from tandems of two or more repeats and form curved solenoid structures that are particularly suitable for protein-protein interactions. Thousands of protein sequences containing leucine-rich repeats have been identified by automatic annotation methods. Three-dimensional structures of leucine-rich repeat domains determined to date reveal a degree of structural variability that translates into the considerable functional versatility of this protein superfamily. As the essential structural principles become well established, the leucine-rich repeat architecture is emerging as an attractive framework for structural prediction and protein engineering. This review presents an update of the current understanding of leucine-rich repeat structure at the primary, secondary, tertiary and quaternary levels and discusses specific examples from recently determined three-dimensional structures.

    Chlamydia infections are common in both men and women, are often asymptomatic and can cause serious complications. Repeat testing in high-risk groups is therefore indicated. In the Netherlands, guidelines on repeat chlamydia testing differ between testing facilities, and knowledge on repeat testing behaviour is limited. Here, we analyse the current repeat testing behaviour of heterosexual STI clinic visitors, and aim to identify groups for which repeat testing advice could be advantageous. Longitudinal surveillance data from all Dutch STI outpatient clinics were used, which included all STI clinic consultations carried out among heterosexual men and women between June 2014 and December 2015. Repeat testing was defined as returning to the same STI clinic between 35 days and 12 months after initial consultation. We calculated chlamydia positivity at repeat test stratified by initial test result and time between consultations. Logistic regression analyses were used to identify predictors of repeat testing, and predictors of having a chlamydia positive repeat test. In total, 140,486 consultations in 75,487 women and 46,286 men were available for analyses. Overall, 15.4% of women and 11.1% of men returned to the STI clinic within the study period. Highest chlamydia positivity at repeat test was seen 3-5 months after initial positive test. Among both women and men, repeat testing was associated with non-Western ethnicity, having had more than two sex partners in the past 6 months, reporting STI symptoms, having a history of STI, and having a chlamydia positive initial test. Among repeat testers, chlamydia positive repeat test was most strongly associated with younger age, followed by a chlamydia positive initial test. Repeat testing most often resulted in a positive test result among young heterosexuals (<25) and heterosexuals of any age with a chlamydia infection at the initial consultation. Further efforts are needed to determine optimal repeat testing strategies.

    Objective: To estimate the relation of single-layer closure at previous caesarean delivery, and other pre-labour and intra-partum risk factors for complete uterine rupture in trial of vaginal birth after a caesarean (TOLAC) at term. Study design: Population-based case-control study. We identified...... all women (n = 39 742) recorded in the Danish Medical Birth Registry (DMBR) during a 12-year period (1997–2008) with a singleton pregnancy at term and TOLAC.

    The authors pose the question - What is the best treatment to reduce the need for caesarean section in nulliparous women at term with delayed first stage of labour? and state in their paper that "There is no consensus on the optimal dose regimen of oxytocin for delay in the first stage of labour...... in nulliparous women at term (37-42 weeks’ gestation) to reduce unplanned caesarean section and increase vaginal birth with minimal adverse events". However, they describe only low and high dose oxytocin regimens and fail to acknowledge that no oxytocin at all is associated with a spontaneous delivery just...... as often as when oxytocin is given (1,2) or that discontinuation of oxytocin once the active phase of labour is reached can result in higher spontaneous delivery rates than continuing oxytocin (3,4). The paper in its list of trials (box 2) only describes those addressing high and low dose oxytocin, which...

    Full Text Available Abstract Background Caesarean section is one of the most commonly performed major operations in women throughout the world. Rates are escalating, with studies from the United States of America, the United Kingdom, China and the Republic of Ireland reporting rates between 20% and 25%.

    2017-01-01

    Full Text Available Background: Oxytocin, a commonly used drug to prevent uterine atony after caesarean section, should be administered as dilute rapid infusion rather than as a bolus. This study was conducted to calculate ED90 of oxytocin infusion during caesarean delivery in parturients at high risk of postpartum haemorrhage (PPH. Materials and Methods: One hundred and twenty parturients having one or more risk factors for PPH received a blinded infusion of oxytocin following emergency caesarean delivery. The initial dose of oxytocin infusion was started as 0.4 IU min−1. The dose of oxytocin infusion for the next parturient was based on the response of preceding patient in increments or decrements of 0.1 IU min−1 as per a biased-coin design up-down sequential method (UDM. Measurements of non-invasive blood pressure and heart rate were taken at 2 min intervals from the time of oxytocin infusion. Intraoperative blood loss was noted. Side effects such as tachycardia, hypotension, nausea, vomiting, chest pain, headache and flushing were also recorded. Results: The ED90 of oxytocin infusion was found to be 0.405 IU min−1 (95% confidence interval 0.3864–0.4125 as calculated by Firth's penalised likelihood estimation using a biased-coin design UDM. Hypotension was observed for brief period of time in 25.6% of parturients and brief period of tachycardia was observed in 9.4% of parturients. No headache, flushing, chest pain and vomiting were observed in any parturients in our study. The estimated blood loss was within the normal limits. Conclusion: Our study showed that ED90 of oxytocin infusion required to achieve adequate uterine tone (UT after an emergency caesarean delivery in parturients at high risk of uterine atony was 0.405 IU min−1. The higher doses of oxytocin did not result in further improvement of UT. Therefore, early use of alternative uterotonic therapy is preferable to achieve adequate UT.

    Full Text Available Hypertrophic obstructive cardiomyopathy (HOCM is a complex cardiovascular disorder with autosomal dominant inheritance and an incidence of 0.1-0.5% in pregnant females. Anaesthetic management of a pregnant female with HOCM posted for elective caesarean section is a challenge, as even minor hemodynamic insults may lead to life-threatening complications. We report successful management of one such patient using epidural anaesthesia with 0.75% Ropivacaine.

    Full Text Available Abstract Background The rate of caesarean delivery (CD in rural China has been rapidly increasing in recent decades. Due to the exorbitant costs associated with CD, paying for this expensive procedure is often a great challenge for the majority of rural families. Since 2003, the Chinese government has re-established the New Cooperative Medical Scheme (NCMS, aimed to improve the access of essential healthcare to rural residents and reduce financial burden owing to high out of pocket payments. This paper seeks to test the hypothesis that NCMS may provide service users and providers with financial incentives to select CD. It also assesses the effect of different health insurance reimbursement strategies of NCMS on CD rates in rural China. Methods Mixed quantitative and qualitative methods were adopted for data collection. Two cross-sectional household surveys were conducted with women having babies delivered in 2006 and 2009; 2326 and 1515 women, respectively, from the study sites were interviewed using structured questionnaires, to collect demographic and socio-economic data, maternal and child care characteristics and health-related expenditures. Focus group discussions (FGDs and in-depth key informant interviews (KIIs were undertaken with policy makers, health managers, providers and mothers to understand their perceptions of the influence of NCMS on the choices of delivery mode. Results The CD rates in the two study counties were 46.0 percent and 64.7 percent in 2006, increasing to 63.6 percent and 82.1 percent, respectively, in 2009. The study found that decisions on the selection of CD largely came from the pregnant women. Logistic regression analysis, after adjusting for socio-economic, maternal and fetal characteristics, did not indicate a significant effect of either proportional reimbursement or fixed amount reimbursement on the choice of CD for both study years. Interviews with stakeholders reflected that different reimbursable rates for

    The ankyrin repeat (ANK) protein family plays a crucial role in plant growth and development and in response to biotic and abiotic stresses. However, no detailed information concerning this family is available for tomato (Solanum lycopersicum) due to the limited information on whole genome sequences. In this study, we identified a total of 130 ANK genes in tomato genome (SlANK), and these genes were distributed across all 12 chromosomes at various densities. And chromosomal localizations of SlANK genes indicated 25 SlANK genes were involved in tandem duplications. Based on their domain composition, all of the SlANK proteins were grouped into 13 subgroups. A combined phylogenetic tree was constructed with the aligned SlANK protein sequences. This tree revealed that the SlANK proteins comprise five major groups. An analysis of the expression profiles of SlANK genes in tomato in different tissues and in response to stresses showed that the SlANK proteins play roles in plant growth, development and stress responses. To our knowledge, this is the first report of a genome-wide analysis of the tomato ANK gene family. This study provides valuable information regarding the classification and putative functions of SlANK genes in tomato. Crown Copyright © 2013. Published by Elsevier B.V. All rights reserved.

  19. The diversity and evolution of Wolbachia ankyrin repeat domain genes.

    Full Text Available Ankyrin repeat domain-encoding genes are common in the eukaryotic and viral domains of life, but they are rare in bacteria, the exception being a few obligate or facultative intracellular Proteobacteria species. Despite having a reduced genome, the arthropod strains of the alphaproteobacterium Wolbachia contain an unusually high number of ankyrin repeat domain-encoding genes ranging from 23 in wMel to 60 in wPip strain. This group of genes has attracted considerable attention for their astonishing large number as well as for the fact that ankyrin proteins are known to participate in protein-protein interactions, suggesting that they play a critical role in the molecular mechanism that determines host-Wolbachia symbiotic interactions. We present a comparative evolutionary analysis of the wMel-related ankyrin repeat domain-encoding genes present in different Drosophila-Wolbachia associations. Our results show that the ankyrin repeat domain-encoding genes change in size by expansion and contraction mediated by short directly repeated sequences. We provide examples of intra-genic recombination events and show that these genes are likely to be horizontally transferred between strains with the aid of bacteriophages. These results confirm previous findings that the Wolbachia genomes are evolutionary mosaics and illustrate the potential that these bacteria have to generate diversity in proteins potentially involved in the symbiotic interactions.

    In recent decades, we have observed a remarkable increase in the rate of caesarean section (CS) in both developed and developing countries, especially in China. According to the World Health Organization (WHO) systematic review, if the increase in CS rate was between 10% and 15%, the maternal and neonatal mortality was decreased. However, above this level, increasing the rate of CS is no longer associated with reduced mortality. To date, no consensus has been reached on the main factors driving the cesarean epidemic. To reduce the progressively increasing rate of CS, we should find indications for the increasing CS rate. The aim of our study was to estimate the change of CS rate of Beijing Obstetrics and Gynecology Hospital and to find the variation of the indications.From January 1995 to December 2014, the CS rate of Beijing Obstetrics and Gynecology Hospital was analyzed. For our analysis, we selected 14,642 and 16,335 deliveries respectively that occurred during the year 2011 and 2014, to analyze the difference of indications, excluding incomplete data and miscarriages or termination of pregnancy before 28 weeks of gestation because of fatal malformations, intrauterine death, or other reasons.The average CS rate during the past 20 years was 51.15%. The highest caesarean delivery rate was 60.69% in 2002; however, the caesarean delivery rate declined to 34.53% in 2014. The obviously different indications were caesarean delivery on maternal request and previous CS delivery. The rate of CS due to maternal request in 2014 was decreased by 8.16% compared with the year 2011. However, the percentage of pregnancy women with a previous CS delivery increased from 9.61% to 20.42% in 3 years. Along with the decline of CS rate, the perinatal mortality and the rate of neonatal asphyxia decreased in 2014 compared with that in 2011.After a series of measures, the CS rate declined indeed. Compared with 2011, the perinatal mortality and the rate of neonatal asphyxia decreased in

    Epidemiological studies relating maternal 25-hydroxyvitamin D (25OHD) with gestational diabetes mellitus (GDM) and mode of delivery have shown controversial results. We examined if maternal 25OHD status was associated with plasma glucose concentrations, risks of GDM and caesarean section in the Growing Up in Singapore Towards healthy Outcomes (GUSTO) study. Plasma 25OHD concentrations, fasting glucose (FG) and 2-hour postprandial glucose (2HPPG) concentrations were measured in 940 women from a Singapore mother-offspring cohort study at 26-28 weeks' gestation. 25OHD inadequacy and adequacy were defined based on concentrations of 25OHD ≤75nmol/l and >75nmol/l respectively. Mode of delivery was obtained from hospital records. Multiple linear regression was performed to examine the association between 25OHD status and glucose concentrations, while multiple logistic regression was performed to examine the association of 25OHD status with risks of GDM and caesarean section. In total, 388 (41.3%) women had 25OHD inadequacy. Of these, 131 (33.8%), 155 (39.9%) and 102 (26.3%) were Chinese, Malay and Indian respectively. After adjustment for confounders, maternal 25OHD inadequacy was associated with higher FG concentrations (β = 0.08mmol/l, 95% Confidence Interval (CI) = 0.01, 0.14), but not 2HPPG concentrations and risk of GDM. A trend between 25OHD inadequacy and higher likelihood of emergency caesarean section (Odds Ratio (OR) = 1.39, 95% CI = 0.95, 2.05) was observed. On stratification by ethnicity, the association with higher FG concentrations was significant in Malay women (β = 0.19mmol/l, 95% CI = 0.04, 0.33), while risk of emergency caesarean section was greater in Chinese (OR = 1.90, 95% CI = 1.06, 3.43) and Indian women (OR = 2.41, 95% CI = 1.01, 5.73). 25OHD inadequacy is prevalent in pregnant Singaporean women, particularly among the Malay and Indian women. This is associated with higher FG concentrations in Malay women, and increased risk of emergency

    The purpose of this study was to assess the repeatability of corneal topography measurements in dry eye patients and healthy controls. Participants underwent consecutive corneal topography measurements (Sirius; Costruzione Strumenti Oftalmici, Florence, Italy). Two images with acquisition quality higher than 90% were accepted. The following parameters were evaluated: minimum and central corneal thickness, aqueous depth, apex curvature, anterior chamber volume, horizontal anterior chamber diameter, iridocorneal angle, cornea volume, and average simulated keratometry. Repeatability was assessed by calculating intra-class correlation coefficient. Thirty-three patients with dry eye syndrome and 40 healthy controls were enrolled to the study. The groups were similar in terms of age (39 [18-65] vs. 30.5 [18-65] years, p=0.198) and gender (M/F: 4/29 vs. 8/32, p=0.366). Intra-class correlation coefficients among all topography parameters within both groups showed excellent repeatability (>0.90). The anterior segment measurements provided by the Sirius corneal topography system were highly repeatable for dry eye patients and are sufficiently reliable for clinical practice and research.

    Seven hundred and fifty five cases of acute non-traumatic subarachnoid hemorrhage (SAH) were admitted to the department of neurosurgery of our hospital from July, 1995 to March, 2004. In 555 patients cerebral angiography was conducted but initial angiography was negative in 30 patients. Except 10 general condition poor patients, in 20 initial angiogram-negative patients were undergone repeated angiography. The cause of SAH could not be demonstrated in 13 cases. The SAH in perimesencephalic and non-perimesencephalic cisturns was seen in 7 and 6 cases, respectively. Occipital and/or neck pain on admission was statistically more common among patients with perimesencephalic SAH than those with non-perimesencephalic SAH (p=0.029), and the prognosis of perimesencephalic SAH was good. We conclude that repeat angiography should not be recommended in patients with perimesencephalic SAH. Patients with non-perimesencephalic SAH had a higher rate of complication. In the non-perimesencephalic group, 3 patients developed hydrocephalus and 3 patients had vasospasm, which were found by repeated angiography. Therefore, repeated angiography is recommended for better clinical outcome by early detection and management of serious complications in this group of patients. (author)

    Background The objective of our study was to describe factors associated with repeat workers' compensation claims and to compare the work disability arising in workers with single and multiple compensation claims. Methods All initial injury claims lodged by persons of working age during a five year period (1996 to 2000) and any repeat claims were extracted from workers' compensation administrative data in the state of Victoria, Australia. Groups of workers with single and multiple claims were identified. Descriptive analysis of claims by affliction, bodily location, industry segment, occupation, employer and workplace was undertaken. Survival analysis determined the impact of these variables on the time between the claims. The economic impact and duration of work incapacity associated with initial and repeat claims was compared between groups. Results 37% of persons with an initial claim lodged a second claim. This group contained a significantly greater proportion of males, were younger and more likely to be employed in manual occupations and high-risk industries than those with single claims. 78% of repeat claims were for a second injury. Duration between the claims was shortest when the working conditions had not changed. The initial claims of repeat claimants resulted in significantly (p claims. Conclusions A substantial proportion of injured workers experience a second occupational injury or disease. These workers pose a greater economic burden than those with single claims, and also experience a substantially greater cumulative period of work disability. There is potential to reduce the social, health and economic burden of workplace injury by enacting prevention programs targeted at these workers. PMID:21696637

    Full Text Available Abstract Background The reproducibility of research is essential to rigorous science, yet significant concerns of the reliability and verifiability of biomedical research have been recently highlighted. Ongoing efforts across several domains of science and policy are working to clarify the fundamental characteristics of reproducibility and to enhance the transparency and accessibility of research. Methods The aim of the proceeding work is to develop an assessment tool operationalizing key concepts of research transparency in the biomedical domain, specifically for secondary biomedical data research using electronic health record data. The tool (RepeAT was developed through a multi-phase process that involved coding and extracting recommendations and practices for improving reproducibility from publications and reports across the biomedical and statistical sciences, field testing the instrument, and refining variables. Results RepeAT includes 119 unique variables grouped into five categories (research design and aim, database and data collection methods, data mining and data cleaning, data analysis, data sharing and documentation. Preliminary results in manually processing 40 scientific manuscripts indicate components of the proposed framework with strong inter-rater reliability, as well as directions for further research and refinement of RepeAT. Conclusions The use of RepeAT may allow the biomedical community to have a better understanding of the current practices of research transparency and accessibility among principal investigators. Common adoption of RepeAT may improve reporting of research practices and the availability of research outputs. Additionally, use of RepeAT will facilitate comparisons of research transparency and accessibility across domains and institutions.

    It is not known if "hospital quality reports" (HQR) document Caesarean (C-) section rates at the hospital level accurately enough for use as a reliable data source when it comes to explaining regional variations of C-sections in Germany by factors at the hospital level. We aimed to answer this question using HQR from hospitals in Baden-Württemberg as data source. Diagnostic and procedure codes from HQR for the year 2008 (HQRdata), were used to calculate numbers of births, numbers of C-sections, and rates of births by C-section (CSR) for 94 of 97 hospitals in Baden-Württemberg. These numbers were compared to internal hospital (IH) data delivered upon request by 80 of 97 hospitals and stemming from vital statistics, birth registry forms, or external quality assurance datasets. There was no difference in the number of births between HQR data and IH data, but the number of C-sections and the CSR differed significantly (pCSR calculated using HQR data was 4.9 ± 17.9% higher than CSR from IH data (absolute difference 1.5 ± 5.8%). The correlation between the 2 data sources was moderate (r=0.73). Only 55% of the variance in IH data-based CSR was explained by HQR data. The proportion between highest and lowest CSR in hospitals in Baden-Württemberg was 4.9 for HQR data and 3.6 for IH data. There are significant and relevant differences between C-section rates based on ei-ther HQR or IH data. This questions routine data from HQR for 2008 as a reliable data source for research work. © Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available Globally the rates of caesarean section (CS have steadily increased in recent decades. This rise is not fully accounted for by increases in clinical factors which indicate the need for CS. We investigated the socio-demographic predictors of CS and the average annual rates of CS in Bangladesh between 2004 and 2014.Data were derived from four waves of nationally representative Bangladesh Demographic and Health Survey (BDHS conducted between 2004 and 2014. Rate of change analysis was used to calculate the average annual rate of increase in CS from 2004 to 2014, by socio-demographic categories. Multi-level logistic regression was used to identify the socio-demographic predictors of CS in a cross-sectional analysis of the 2014 BDHS data.CS rates increased from 3.5% in 2004 to 23% in 2014. The average annual rate of increase in CS was higher among women of advanced maternal age (≥35 years, urban areas, and relatively high socio-economic status; with higher education, and who regularly accessed antenatal services. The multi-level logistic regression model indicated that lower (≤19 and advanced maternal age (≥35, urban location, relatively high socio-economic status, higher education, birth of few children (≤2, antenatal healthcare visits, overweight or obese were the key factors associated with increased utilization of CS. Underweight was a protective factor for CS.The use of CS has increased considerably in Bangladesh over the survey years. This rising trend and the risk of having CS vary significantly across regions and socio-economic status. Very high use of CS among women of relatively high socio-economic status and substantial urban-rural difference call for public awareness and practice guideline enforcement aimed at optimizing the use of CS.

    Post-traumatic stress disorder (PTSD) occurs in 1-7% of women following childbirth. While having a caesarean section (C-section) is known to be a significant risk factor for postpartum PTSD, it is currently unknown whether coexisting anaesthesia-related factors are also associated to the disorder. The aim of this study was to assess anaesthesia-linked factors in the development of acute postpartum PTSD. We performed a prospective cohort study on women having a C-section in a tertiary hospital in Switzerland. Patients were followed up six weeks postpartum. Patient and procedure characteristics, past morbidity or traumatic events, psychosocial status and stressful perinatal events were measured. Outcome was divided into two categories: full PTSD disease and PTSD profile. This was based on the number of DSM-IV criteria of the Diagnostic and Statistical Manual of Mental Disorders 4th edition (DSM-IV) present. The PTSD Checklist Scale and the Clinician Administered PTSD Scale were used for measurement. Of the 280 patients included, 217 (77.5%) answered the questionnaires and 175 (62.5%) answered to an additional phone interview. Twenty (9.2%) had a PTSD profile and six (2.7%) a PTSD. When a full predictive model of risk factors for PTSD profile was built using logistic regression, maternal prepartum and intrapartum complications, anaesthetic complications and dissociative experiences during C-section were found to be the significant predictors for PTSD profile. This is the first study to show in parturients having a C-section that an anaesthesia complication is an independent risk factor for postpartum PTSD and PTSD profile development, in addition to known perinatal and maternal risk factors.
