Women's preference for a cesarean section: incidence and associated factors

Abstract: Background:Few studies have examined women's preferences for birth. The object of this study was to determine the incidence of women's preferred type of birth, and the reasons and factors associated with their preference.Methods:Three hundred and ten women between 36 and 40 weeks' gestation were recruited from the antenatal clinic of a major metropolitan teaching hospital and the consulting rooms of six private obstetricians in Brisbane, Australia. Participants completed a questionnaire asking about their preferred type of birth, reasons for their preference, preparation for childbirth, level of anxiety and concerns, and the influence of the primary caregiver.Results:Two hundred and ninety women (93.5%) preferred a spontaneous vaginal birth; 20 women (6.4%) preferred a cesarean section. Of the latter group, most had a current obstetric complication or experienced a previously complicated delivery (p <0.001); 1 woman (0.3%) preferred a cesarean section in the absence of any known current or previous obstetric complication. Women who preferred a cesarean section were more anxious, were generally poorly informed of the risks of this procedure, and/or overestimated the safety of the procedure.Conclusions:Women who preferred a cesarean section were more likely to have experienced this type of birth previously and to have negative feelings about it. To decrease women's preference for a cesarean section, practitioners should reduce the primary cesarean delivery rate and improve the quality of emotional care for women who require a cesarean section. Caregivers should engage in a sensitive discussion of the risks and benefits of various birth options, including a vaginal birth after cesarean, with women who have previously experienced a cesarean birth before they make decisions about mode of delivery in a subsequent pregnancy.

Accuracy and Reliability of Methods to Measure Marginal Adaptation of Crowns and FDPs: A Literature Review

Abstract: Purpose To review methods used to investigate marginal adaptation of crowns and fixed dental prostheses (FDPs), and to discuss testing variables employed and their influence on results. Methods Online libraries including PubMed, Scopus, and Ovid were searched for articles evaluating the marginal adaptation of crowns and FDPs using a combination of the keywords: “marginal accuracy,” “marginal fit,” “marginal gap,” “marginal discrepancy,” “fitting accuracy,” “crown,” and “FPD.” Peer-reviewed publications in English in the period 1970 to December 2011 were collected, evaluated by their abstract, and included if they met the inclusion criteria. The criteria involved studies evaluating marginal adaptation of crowns and FDPs through clear experimental protocols. Exclusion criteria involved longitudinal prospective and retrospective clinical evaluations, studies using subjective tactile sensation, and other predefined criteria. Results A total of 277 papers were identified; only 183 met the inclusion criteria. Direct view technique was used by 47.5% of the articles followed by cross-sectioning (23.5%), and impression replica (20.2%) techniques. The marginal gap values reported by these techniques varied among individual crown systems and across different systems because of variations in study type (in vivo vs. in vitro), sample size and measurements per specimen, finish line design, and stage at which the marginal gap was measured. Conclusion There was a substantial lack of consensus relating to marginal adaptation of various crown systems due to differences in testing methods and experimental protocols employed. Direct view technique was the most commonly used method of reproducible results. Also, conducting an experimental set-up of testing a minimum of 30 specimens at 50 measurements per specimen should produce reliable results. Additionally, using a combination of two measurement methods can be useful in verification of results.

Work/Family Conflict, Psychological Well-Being, Satisfaction and Social Support: A Longitudinal Study in New Zealand

Abstract: A survey of employed workers was conducted at two time periods to assess relationships between work‐family conflict, well‐being, and job and family satisfaction, along with the role of social support from work colleagues and family members Levels of work‐to‐family interference (WFI) were found to be uniformly higher than family‐to‐work interference (FWI) However, at each time period FWI showed more consistent negative relationships with well‐being and satisfaction, indicating that family‐to‐work interference may have a greater bearing on employees’ affective reactions There were few cross‐time relationships between work‐family conflict and these reactions, which suggests that the association of work‐family conflict with well‐being and satisfaction may be time‐dependent Although there was some evidence that social support from work colleagues moderated the relationship of WFI with psychological strain and family satisfaction, family support did not display a consistent moderator influence Instead, both forms of support tended to exhibit direct (rather than moderator) relationships with the outcome variables Implications of the findings for research and interventions are discussed

Psychological characteristics, stressful life events and deliberate self-harm: findings from the Child & Adolescent Self-harm in Europe (CASE) Study.

Abstract: There is evidence to suggest that both psychological characteristics and stressful life events are contributory factors in deliberate self-harm among young people. These links, and the possibility of a dose-response relationship between self-harm and both psychological health and life events, were investigated in the context of a seven-country school-based study. Over 30,000, mainly 15 and 16 year olds, completed anonymous questionnaires at secondary schools in Belgium, England, Hungary, Ireland, the Netherlands, Norway and Australia. Pupils were asked to report on thoughts and episodes of self-harm, complete scales on depression and anxiety symptoms, impulsivity and self-esteem and indicate stressful events in their lives. Level and frequency of self-harm was judged according to whether they had thought about harming themselves or reported single or multiple self-harm episodes. Multinomial logistic regression assessed the extent to which psychological characteristics and stressful life events distinguished between adolescents with different self-harm histories. Increased severity of self-harm history was associated with greater depression, anxiety and impulsivity and lower self-esteem and an increased prevalence of all ten life event categories. Female gender, higher impulsivity and experiencing the suicide or self-harm of others, physical or sexual abuse and worries about sexual orientation independently differentiated single-episode self-harmers from adolescents with self-harm thoughts only. Female gender, higher depression, lower self-esteem, experiencing the suicide or self-harm of others, and trouble with the police independently distinguished multiple- from single-episode self-harmers. The findings reinforce the importance of psychological characteristics and stressful life events in adolescent self-harm but nonetheless suggest that some factors are more likely than others to be implicated.
