Difficulties quitting for smokers with and without a respiratory disease and use of a tailored intervention for smoking cessation – a qualitative study

Introduction: Smokers with respiratory diseases are less likely to quit than those without impaired lung function, yet few studies have investigated the effectiveness of smoking cessation interventions with this population, and none have used a computer-tailored approach. Aims: This paper aims to fill this gap in the literature by exploring smokers’ experiences when trying to quit and their perceptions of a computer-tailored intervention. Methods: Semi-structured interviews were conducted with 26 smokers recruited from six GP practices in North London. Thematic analysis was conducted to examine participants’ previous experiences of quitting and their perceptions of receiving personal tailored feedback reports to aid smoking cessation. Results: Participants discussed how their positive smoking experiences coupled with their negative cessation experiences led to conflicts with quitting smoking. Although the computer-tailored intervention was key in prompting quit attempts and participants valued its personal approach; it was not sufficient as a stand-alone intervention. Conclusion: The results highlight the difficulties that smokers experience when quitting and the need for a more personalised stop smoking service in smokers with respiratory diseases. The study also demonstrates the application and potential for computer tailored intervention as part of a wider programme of long-term smoking cessation

Transition to parenthood after successful non-donor in vitro fertilisation: The effects of infertility and in vitro fertilisation on previously infertile couples' experiences of early parenthood

Recent social science research in the field of parenting following assisted conception has focused on the experiences of donor assisted conception and surrogacy. This paper draws from a study which explored the experiences of the transition to early parenthood in 16 heterosexual non-donor couples and includes a specific consideration of the experiences of men as they navigate this journey. We argue that these couples’ transition to early parenthood can be as complex and provisional as in other newer forms of family making as they struggle with an emerging identity as a parent after successful non-donor IVF following their experiences of infertility. Their family making is contingent upon their ability to work at integrating their experiences of infertility and IVF into their emerging identity as a parent. This struggle is prominent when they contemplate a further pregnancy. Considering a sibling causes them further uncertainty and anxiety because it reminds them of their infertile identify and the possibility of further IVF. We report novel findings about the experiences of this transition to parenthood: how couples’ identity as parents is shaped by the losses and grief of infertility and the anxiety of IVF. We argue that their struggle with an emerging parenthood identity challenges the normative, naturalised view of non-donor heterosexual IVF parenthood. Our work contributes to the work on identity in parenthood after IVF in an ongoing effort to understand how assisted technologies shape infertile parents’ lives. This paper reports a small study with a relatively homogenous sample recruited from one fertility clinic. Nevertheless as an exploratory study of an under researched topic, we discuss useful insights and ideas for further research with larger and more diverse samples

An integrative literature review of psychosocial factors in the transition to parenthood following non-donor-assisted reproduction compared with spontaneously conceiving couples

An integrative literature review of research into the psychosocial factors which shape the transition to parenthood in couples following non-donor in vitro fertilisation in comparison with spontaneously conceiving couples was undertaken following adapted PRISMA guidelines. Nineteen papers of non-donor IVF and SC mothers and fathers were included in the review. This is the first review to report on research comparing the transition to parenthood of couples following successful non-donor singleton AR and SC couples. The small number of studies were over reliant on survey methodologies. Differences between groups were reported on a range of psychosocial measures during the transition from pregnancy to parenthood: locus of control, parental adjustment and child behaviour, parental stress, parental investment in the child, self-esteem and self-efficacy, greater levels of protectiveness (separation anxiety) towards child, marital and family functioning, family alliance, marital satisfaction and communication as well anxiety, indirect aggression and less respect for child. We have conceptualised these differences as three substantive themes which reflect psychosocial factors shaping transition to parenthood in parents after non-donor AR: social support, relationships, and emotional well-being which are in turn intersected by gender differences. These findings have implications for health care professionals’ assessment of individual couples’ support needs

Introduction. This study was performed to assess the applicability of the WHO Maternal Near Miss Tool (MNM Tool) and the organ dysfunction criteria in a high-income country. Material and methods. The MNM tool was applied to 2552 women who died of pregnancy-related causes or sustained severe acute maternal morbidity between August 2004 and August 2006 in one of the 98 hospitals with a maternity unit in the Netherlands. Fourteen (0.6%) cases had insufficient data for application. Each case was assessed according to the three main "MNM categories" specified in the MNM tool and their subcategory criteria: five disease-, four intervention- and seven organ dysfunction-based criteria. Potentially life-threatening conditions (disease-based inclusions) and life-threatening cases (organ dysfunction-based inclusions) were differentiated according to WHO methodology. Outcomes were incidence of all (sub)categories and case-fatality rates. Results. Of the 2538 cases, 2308 (90.9%) women fulfilled disease-based, 2116 (83.4%) intervention-based and 1024 (40.3%) organ dysfunction-based criteria. Maternal death occurred in 48 women, of whom 23 (47.9%) fulfilled disease-based, 33 (68.8%) intervention-based and 31 (64.6%) organ dysfunction-based criteria. Case-fatality rates were 23/2308 (1.0%) for cases fulfilling the disease-based criteria, 33/2116 (1.6%) for intervention-based criteria and 31/1024 (3.0%) for women fulfilling the organ dysfunction-based criteria. Conclusions. In the Netherlands, where advanced laboratory and clinical monitoring are available, organ dysfunction-based criteria of the MNM tool failed to identify nearly two-thirds of sustained severe acute maternal morbidity cases and more than one-third of maternal deaths. Disease-based criteria remain important, and using only organ dysfunction-based criteria would lead to underestimating severe acute maternal morbidity

Development and validation of the Religious Collective Self-Esteem scale for children

This study aimed to validate a Religious Collective Self-Esteem Scale (RCSES) that assesses children’s evaluations and judgments about their belonging to a religious group. The RCSES includes 3 subscales: Private Religious Self-Esteem (PrRSE), Public Religious Self-Esteem (PuRSE), and Importance to Religious Identity (RI). Data were gathered from students in 39 primary schools (9 Reformed Protestant, 9 Islamic, 3 Hindu and 18 public schools) across five regions in the Netherlands. Students were asked to complete an anonymous questionnaire containing measures of variables of interest. Subjects were 1,437 6th graders (Mage = 11.72, SD = 0.61; 51.7% girls. 680 Students identified themselves as Muslim (47.3%), 442 (30.8%) as Christian, 278 (19.3%) as Hindu, and 37 (2.6%) children had another religion. Results indicated sufficient internal consistency of RCSES (α = .80), PrRSE (α = .77), PuRSE (α = .73), and RI (α = .60), moderate to high correlations between the subscales and moderate to large test–retest reliability across 1 year (r = .57). Three-factor model fitted the best. Overall, findings support partial measurement and structural invariance across religious groups. Convergent validity was supported by small to moderate correlations with other scales (Individual Self-Esteem Scale, r = .29; Private Ethnic Self-Esteem Scale (PESES), r = .40). Divergent validity was supported by positive small significant correlations with school well-being (r = .18) and social school motivation (r = .19). RCSES and its subscales significantly predicted, over and above PESES, school well-being and school motivation scores. Findings support the reliability and validity of the RCSES for assessing religious collective self-esteem. (PsycINFO Database Record (c) 2017 APA, all rights reserved

The 5T mouse multiple myeloma model: absence of c-myc oncogene rearrangement in early transplant generations.

Consistent chromosomal translocations involving the c-myc cellular oncogene and one of the three immunoglobin loci are typical for human Burkitt's lymphoma, induced mouse plasmacytoma (MPC) and spontaneously arising rat immunocytoma (RIC). Another plasma cell malignancy, multiple myeloma (MM), arising spontaneously in the ageing C57BL/KaLwRij mice, was investigated in order to see whether the MM cells contain c-myc abnormalities of the MPC or RIC type. Rearrangement of the c-myc oncogene was found in the bone marrow cells only in 5T2 MM transplantation line in a mouse of the 24th generation and in none of the seven other MM of the 5T series which were of earlier generations. Since the mouse 5T MM resembles the human MM very closely, including the absence of consistent structural c-myc oncogene abnormalities, it can serve as a useful experimental model for studies on the aetiopathogenesis of this disease
