You see but you do not observe: A review of bystander intervention and sexual assault on university campuses

Sexual assault on university campuses has garnered increased attention in recent years. A systematic review was conducted to identify the factors associated with bystander intervention regarding sexual assault on university campuses. Currently, no published systematic reviews exist within this area. Twenty-eight studies were reviewed according to four major bystander factors: rape myth and date rape attitudes; bystander efficacy; bystander intent; and bystander behavior. There was a heavy emphasis on bystander intent and behavior throughout. Three important limitations were identified: (1) all empirical research has been conducted in the USA, yet bystander intervention programs exist outside of the USA, in countries such as the UK, (2) a majority of the studies employed quantitative methodologies and so failed to capture important details such as bystanders' perceptions of sexual assault or what other factors influence the likelihood of intervening, and (3) there were limited attempts to control for factors such as social desirability. This area of research is still in its infancy. Future research should examine in greater detail the factors inhibiting and facilitating bystander intervention. Finally, research outside of the USA is important in developing the literature in this area to effectively inform bystander intervention programs

UK and Australian University Students’ Perceptions of the Nature of Sexual Assault and Intervening Behavior

Sexual assault is a global problem, with the risk highest among university students. Bystander intervention preventing sexual assaults has primarily been researched using quantitative methods to understand what factors influence it. However, both sexual assault and bystander intervention are complex with many subtle and overlapping issues that, when analyzed qualitatively, can offer new insights. The current study aimed to explore and develop a nuanced and comprehensive understanding of students’ perceptions of sexual assault and bystander intervention across two universities, one in the United Kingdom and one in Australia. Thirty-nine university students (19 in the United Kingdom; 20 in Australia) took part in one-to-one semistructured interviews. Using inductive thematic analysis, two overarching themes were identified: (a) navigating the complex dynamics of sexual assault; and (b) decisions to intervene or not to intervene. Findings suggest that the complexity and ambiguity around sexual assault can forestall bystander intervention. As such, increasing education, awareness, and discussions around sexual assault and bystander intervention is vital to increase awareness of the problem and mobilize action from bystanders to prevent sexual assault

Radiotherapy exposure directly damages the uterus and causes pregnancy loss

Female cancer survivors are significantly more likely to experience infertility than the general population. It is well established that chemotherapy and radiotherapy can damage the ovary and compromise fertility, yet the ability of cancer treatments to induce uterine damage, and the underlying mechanisms, have been understudied. Here, we show that in mice total-body γ-irradiation (TBI) induced extensive DNA damage and apoptosis in uterine cells. We then transferred healthy donor embryos into ovariectomized adolescent female mice that were previously exposed to TBI to study the impacts of radiotherapy on the uterus independent from effects to ovarian endocrine function. Following TBI, embryo attachment and implantation were unaffected, but fetal resorption was evident at midgestation in 100% of dams, suggesting failed placental development. Consistent with this hypothesis, TBI impaired the decidual response in mice and primary human endometrial stromal cells. TBI also caused uterine artery endothelial dysfunction, likely preventing adequate blood vessel remodeling in early pregnancy. Notably, when pro-apoptotic protein Puma-deficient (Puma-/-) mice were exposed to TBI, apoptosis within the uterus was prevented, and decidualization, vascular function, and pregnancy were restored, identifying PUMA-mediated apoptosis as a key mechanism. Collectively, these data show that TBI damages the uterus and compromises pregnancy success, suggesting that optimal fertility preservation during radiotherapy may require protection of both the ovaries and uterus. In this regard, inhibition of PUMA may represent a potential fertility preservation strategy.</p

A multiorganism pipeline for antiseizure drug discovery:Identification of chlorothymol as a novel γ-aminobutyric acidergic anticonvulsant

OBJECTIVE:Current medicines are ineffective in approximately one-third of people with epilepsy. Therefore, new antiseizure drugs are urgently needed to address this problem of pharmacoresistance. However, traditional rodent seizure and epilepsy models are poorly suited to high-throughput compound screening. Furthermore, testing in a single species increases the chance that therapeutic compounds act on molecular targets that may not be conserved in humans. To address these issues, we developed a pipeline approach using four different organisms. METHODS:We sequentially employed compound library screening in the zebrafish, Danio rerio, chemical genetics in the worm, Caenorhabditis elegans, electrophysiological analysis in mouse and human brain slices, and preclinical validation in mouse seizure models to identify novel antiseizure drugs and their molecular mechanism of action. RESULTS:Initially, a library of 1690 compounds was screened in an acute pentylenetetrazol seizure model using D rerio. From this screen, the compound chlorothymol was identified as an effective anticonvulsant not only in fish, but also in worms. A subsequent genetic screen in C elegans revealed the molecular target of chlorothymol to be LGC-37, a worm γ-aminobutyric acid type A (GABAA ) receptor subunit. This GABAergic effect was confirmed using in vitro brain slice preparations from both mice and humans, as chlorothymol was shown to enhance tonic and phasic inhibition and this action was reversed by the GABAA receptor antagonist, bicuculline. Finally, chlorothymol exhibited in vivo anticonvulsant efficacy in several mouse seizure assays, including the 6-Hz 44-mA model of pharmacoresistant seizures. SIGNIFICANCE:These findings establish a multiorganism approach that can identify compounds with evolutionarily conserved molecular targets and translational potential, and so may be useful in drug discovery for epilepsy and possibly other conditions

“I was a full time proper smoker”: A qualitative exploration of smoking in the home after childbirth among women who relapse postpartum

Background: Many women stop smoking during pregnancy but relapse shortly afterwards, potentially putting their infants at risk of secondhand smoke (SHS) exposure. Women who were able to stop during pregnancy may be a motivated group, receptive to making behaviour changes postpartum to protect their infant from SHS exposure. Understanding more about their experiences of relapse, and if this influences home smoking behaviours and children’s exposure to SHS in the home may help to inform intervention development to prevent infant SHS exposure. Methods: Guided by interpretative phenomenological methodology we conducted and analysed nine semi-structured interviews with women who quit smoking during pregnancy, but relapsed ≤3 months postpartum. Findings: Central to mothers’ accounts of their smoking behaviours during pregnancy and postpartum was their desire to be a ‘responsible mother’. Mothers described using strategies to protect their infant from SHS exposure, and held strong negative attitudes towards other smoking parents. After relapsing, mothers appeared to reposition themselves as ‘social’ or ‘occasional’ smokers rather than ‘regular’ smokers Conclusions: Findings suggest that interventions to prevent/reduce infants' home SHS exposure should build on mothers' intentions to be responsible parents. As mothers who relapse principally view themselves as ‘social’ or ‘occasional’ smokers, interventions that are highlighted as relevant for women with these types of smoking patterns may be more likely to be responded to, and, ultimately, be effective

Using Theory to Understand the Barriers to Engagement in Group Offending Behavior Programs

Noncompletion of group offending behavior programs is a common problem, indicating barriers to engagement. While existing theoretical models have accounted for determinants of motivation, little focus has been directed towards barriers to engagement. The authors developed the program engagement theory (PET) which not only accounts for the determinants of engagement and the engagement process, it also considers the barriers to engagement. Interviews and session observations were used to collect data from 23 program facilitators and 28 offenders, which were analyzed using grounded theory. The barriers to engagement were classified as program and referral factors (uninformative referrals, offense-focused programs, rigid and abstract content, didactic delivery, and homework), facilitator characteristics (lack of control: contentious and nonassertive), and group member characteristics (unmotivated, pre-contemplative, and blaming others and young, chaotic, and disruptive). Suggestions as to the design and facilitation of group offending behavior programs, and facilitator training and supervision to overcome barriers to engagement are proposed

Key mechanisms by which post-ICU activities can improve in-ICU care: results of the international THRIVE collaboratives

Objective: To identify the key mechanisms that clinicians perceive improve care in the intensive care unit (ICU), as a result of their involvement in post-ICU programs. Methods: Qualitative inquiry via focus groups and interviews with members of the Society of Critical Care Medicine’s THRIVE collaborative sites (follow-up clinics and peer support). Framework analysis was used to synthesize and interpret the data. Results: Five key mechanisms were identified as drivers of improvement back into the ICU: (1) identifying otherwise unseen targets for ICU quality improvement or education programs—new ideas for quality improvement were generated and greater attention paid to detail in clinical care. (2) Creating a new role for survivors in the ICU—former patients and family members adopted an advocacy or peer volunteer role. (3) Inviting critical care providers to the post-ICU program to educate, sensitize, and motivate them—clinician peers and trainees were invited to attend as a helpful learning strategy to gain insights into post-ICU care requirements. (4) Changing clinician’s own understanding of patient experience—there appeared to be a direct individual benefit from working in post-ICU programs. (5) Improving morale and meaningfulness of ICU work—this was achieved by closing the feedback loop to ICU clinicians regarding patient and family outcomes. Conclusions: The follow-up of patients and families in post-ICU care settings is perceived to improve care within the ICU via five key mechanisms. Further research is required in this novel area
