Dysregulated RNA polyadenylation contributes to metabolic impairment in non-alcoholic fatty liver disease.

Pre-mRNA processing is an essential mechanism for the generation of mature mRNA and the regulation of gene expression in eukaryotic cells. While defects in pre-mRNA processing have been implicated in a number of diseases their involvement in metabolic pathologies is still unclear. Here, we show that both alternative splicing and alternative polyadenylation, two major steps in pre-mRNA processing, are significantly altered in non-alcoholic fatty liver disease (NAFLD). Moreover, we find that Serine and Arginine Rich Splicing Factor 10 (SRSF10) binding is enriched adjacent to consensus polyadenylation motifs and its expression is significantly decreased in NAFLD, suggesting a role mediating pre-mRNA dysregulation in this condition. Consistently, inactivation of SRSF10 in mouse and human hepatocytes in vitro, and in mouse liver in vivo, was found to dysregulate polyadenylation of key metabolic genes such as peroxisome proliferator-activated receptor alpha (PPARA) and exacerbate diet-induced metabolic dysfunction. Collectively our work implicates dysregulated pre-mRNA polyadenylation in obesity-induced liver disease and uncovers a novel role for SRSF10 in this process.

Laypeople's perceptions of the effects of event repetition, reporting delay, and emotion on children's and adults' memory.

For crimes such as child abuse and family violence, jurors' assessments of memory reports from key witnesses are vital to case outcomes in court. Since jurors are not experts on memory, the present research measured laypeople's (i.e., non-experts') beliefs about how three key factors affect witnesses' memory reports for an experienced event: how frequently an event was experienced (repeated, single), the delay between experiencing and reporting the event, and the emotional valence of the event. Across two studies, lay participants completed an online survey that measured their beliefs about each factor. In Study 1, 51 participants completed a survey about how the three factors affect children's memory. In Study 2, another 51 participants completed a survey about how the three factors affect adult's memory. Across both studies, delays were believed to worsen memory, and emotion was believed to improve memory. Beliefs about single and repeated events showed different patterns across the studies. In Study 1, participants' beliefs about children's memory for repeated experience were variable. In Study 2, participants believed that adults' memory was worse for repeated events than single events. Overall, laypeople demonstrated many accurate beliefs about memory, but showed some confusion about children's memory for repeated events.

The effects of episode spacing on adult's reports of a repeated event.

Witnesses' reports of repeated events have been the focus of much research; however, the spacing interval between each episode of the event has differed greatly. The aim of the current study was to determine whether spacing interval affects participants' memory reports. Adults (N = 217) watched one (n = 52) or four videos depicting workplace bullying. The repeated event participants watched the four videos all in one day (n = 55), one per day over four consecutive days (n = 60), or one every three days over 12 days (n = 50). One week after the last (or only) video, participants reported on that video and answered some reflective questions about the procedure. Repeated-event participants also reported on what usually happens across the videos. Single-event participants reported proportionally more accurate information about the target video than repeated-event participants, and spacing interval did not affect repeated event participants' accuracy. However, accuracy scores were close to ceiling while errors rates were at floor levels, preventing us from drawing strong conclusions. We found some evidence that episode spacing affected participants' perceptions of their memory performance. Overall, spacing may have a minimal effect on adults' memory for repeated events, but further research is required.

Reconsidering post 20-week abortion in Aotearoa New Zealand.

The Abortion Legislation Act 2020 established comprehensive grounds for approving abortions after 20 weeks. These grounds are less restrictive than before law reform. They give qualified health practitioners (QHP) the scope to approve any abortion anyone wants and might reasonably request, if the QHP believes the abortion is clinically justified in the circumstances, having considered all the factors required by law. Because patients hold QHPs accountable under the Health and Disability Commission and legal processes, it is unlikely a QHP will need to justify approving an abortion, although they may well be called upon to justify refusing one.

Disparities in utilisation of combined oral contraceptives in Aotearoa New Zealand: A cross-sectional whole-of-population study.

AIMS: The combined oral contraceptive (COC) is the most commonly used hormonal contraceptive in Aotearoa New Zealand (Aotearoa/NZ). Currently there is limited data available on who uses COC in Aotearoa/NZ. The aims were to (i) define the population of reproductive-aged females in Aotearoa/NZ in 2018 and identify the rate of COC use among this group and (ii) describe the sociodemographic and geographic characteristics of the population of COC users compared to the general population of reproductive-aged females in 2018. METHODS: This whole-of-population cross-sectional study used the Integrated Data Infrastructure, a large research database managed by Statistics New Zealand. Females aged 16-50 years with complete sociodemographic and geographic information in 2018 from Aotearoa/NZ's estimated resident population were included. COC dispensing records to this cohort were identified from the national Pharmaceutical Collection. This paper reports descriptive counts of COC use and employs generalised linear regression with a binomial distribution and a log link to estimate adjusted risk ratios (aRR) of COC use for key sociodemographic and geographic subgroups. RESULTS: Of 1 113 750 individuals in the study, 159 789 (14.3%) were dispensed as COC in 2018. European/other individuals were most likely to use COC (aRR: 2.72, 2.67-2.78), and Pacific Peoples were least likely (aRR: 0.56, 0.55-0.58) to use COC. Individuals residing in the most deprived quintile had less COC use than individuals in the least deprived quintile (aRR: 0.73, 0.72-0.74). CONCLUSION: Our study is able to highlight significant disparities in use by ethnicity, area-level deprivation, and geographic factors.

Adult memory for instances of emotionally stressful and non-stressful repeated events.

Repeated offences, such as domestic violence, are often distressing for victims. When victims of such offences make an allegation of abuse, they are usually required to report details about specific incidents. Therefore, this pre-registered study examined whether memory for an emotionally stressful versus non-stressful repeated event would differ depending on the instance being recalled. Eighty female participants (Mage = 22.3, SD = 7.4) imagined being involved in four abusive (emotionally stressful repeated event) or non-abusive relationship instances (non-stressful repeated event) over a four-week period. One-week after the last instance, participants completed recall and source memory questions about each instance. We found no evidence that memory for stressful versus non-stressful repeated events differed depending on the instance being recalled. Instead, we found that memory was more accurate for the last instance relative to the other instances (i.e., recency effect), regardless of event stressfulness. We also found that memory accuracy was better across all instances in the stressful than the non-stressful group. The findings suggest that victim-survivors of abuse might find the last instance of abuse particularly memorable when the delay between the offence and report is one-week or less, and the stressfulness of the instance might help them recall more details.

Does experiencing inattentional blindness for crime influence eyewitness recall?

Witnesses may not notice crimes occurring when their attention is elsewhere, which may affect their memory. In this study, 174 participants completed an attention-demanding task while viewing a video containing an assault. Whether participants noticed the assault or experienced inattentional blindness for it was assessed. Then, participants were exposed to post-event information (containing misinformation) before completing a cued-recall task under one of three recall instructions (free, forced, or no instruction). Most participants experienced inattentional blindness for the assault (65.5%), which had a negative effect on recall, regardless of recall instruction. Specifically, participants who experienced inattentional blindness were less confident, complete, and accurate, and were more likely to report misinformation, than participants who noticed the crime. Witnesses who experienced inattentional blindness reported that they relied purely on post-event information to answer some questions. The findings suggest that caution should be taken when interviewing witnesses who have not paid attention to a crime.

Willing but not able: A survey of New Zealand health practitioners' interests in providing second trimester abortion care and the obstacles they face.

BACKGROUND: In 2020, abortion was removed from the Crimes Act. Abortions under 20 weeks gestation no longer require an indication and criteria for abortion above 20 weeks gestation has broadened. Prior to law reform, all abortions were provided on licensed premises and the responsible health practitioner was a doctor. Subsequently, any health practitioner with abortion in their scope of practice can provide abortion care. AIMS: To describe the characteristics of health practitioners who expressed an interest in participating in second trimester abortion care, and to identify and describe the barriers to providing an optimal second trimester abortion service. MATERIALS AND METHODS: This was an exponential non-discriminating snowball email survey using tick boxes and open comments. Quantitative data were analysed using descriptive statistics and free-text components were analysed using a general inductive approach. RESULTS: The 113 respondents included: 38 hospital-based obstetrics and gynaecology doctors, 22 primary care doctors, 13 midwives and 14 nurses/nurse practitioners. Thirty-three (29.2%) and 62 (54.9%) respondents reported interest in providing second trimester surgical and medical abortion care respectively. The most commonly identified barrier to both surgical and medical second trimester abortion provision was lack of trained staff, followed by an unsupportive work environment. Thematic analysis aligned with these findings and commonly featured difficulty in accessing feticide. CONCLUSIONS: We need to actively recruit and train all health practitioners interested in providing second trimester abortion care to strengthen the workforce. This requires an organisation to oversee an inclusive national framework for abortion training, including feticide, and provide professional supervision.

Leaps ahead in law but not in practice: Why we need to train in second trimester abortion care.

BACKGROUND: Abortion care has always been controversial, with health professionals worldwide continually working to offer well-rounded safe services. Key improvements in New Zealand since abortion law reform include the ability to self-refer, no formal certification under 20 weeks gestation, and change to the indications for abortion after 20 weeks. Nationally, we know that the second trimester abortion incidence is stable, and will therefore require an ongoing workforce to sustain the service. AIMS: To document the current second trimester workforce for medical and surgical abortion in New Zealand, and examine their training and practice. MATERIALS AND METHODS: Anonymous non-discriminatory snowball survey covering the domains of demographics, barriers to abortion care, abortion training, abortion provision and procedure specifics using Qualtrics software. RESULTS: Eleven practitioners currently perform dilation and evacuation, and 33 wish to. Current providers have between zero and three other colleagues to assist them in service provision. Most learned by an informal apprenticeship model and operate relatively infrequently. There is variance in the cervical preparation and evacuation procedure as well as skillset and/or willingness for later gestations. Fifty-nine practitioners' units currently provide medical abortion, and 62 wish to. There is more coherence in the regime of medical abortion, although the availability of this is affected by gestation and location. CONCLUSION: For most women requesting second trimester abortions, additional time, cost and stress is still very much the status quo. District Health Boards need to prioritise training and workforce planning to ensure the availability of this essential service.

The perceived credibility of repeated-event witnesses depends upon their veracity.

For repeated crimes like domestic violence and workplace bullying, the primary evidence is often the alleged victim's testimony. Consequently, the perceived credibility of repeated event speakers can be pivotal to legal proceedings. In order to investigate perceptions of truthful and deceptive repeated-event speakers, undergraduate students observed interviews of speakers describing a single occurrence of an event that was either experienced or fabricated either once or multiple times. Some participants additionally read an expert statement on repeated-event memory. The effect of repetition on perceived credibility depended on the speaker's veracity, enhancing the credibility of fabricators but diminishing the credibility of truth-tellers. The expert testimony was found to raise the perceived honesty and cognitive competence of the repeated-event speakers and thus could be a promising mechanism for enhancing perceived credibility in legal proceedings.

The effects of immediate recall and subsequent retrieval strategy on eyewitness memory.

The current study investigated the effects of immediate recall and subsequent interview on mock witnesses' memory of a crime. After watching a video of a crime, 111 participants were randomly allocated to an immediate recall condition (the iWitnessed mobile app, free recall). One week later, participants were randomly allocated to a retrieval condition (timeline aid, category clustering recall, free recall). Results showed that iWitnessed elicited more correct details than free recall at immediate recall (Time 1), without compromising accuracy. However, the immediate recall tool did not affect memory performance at a one-week delay (Time 2). At Time 2, participants with retrieval support (timeline aid, category clustering recall) reported more details than those with no retrieval support (free recall), without compromising accuracy. The findings highlight that high-quality immediate recall and retrieval support during a subsequent interview are necessary to elicit more complete and accurate accounts.

The impact of recall timing on the preservation of eyewitness memory.

Two studies investigated the impact of recall timing on eyewitness memory. In Study 1, participants viewed a crime video and then completed the Self-Administered Interview (SAI©) either immediately, after a 24-h delay, after a 1-week delay, or not at all. All participants completed a final recall questionnaire 2 weeks after they had viewed the stimulus video. Study 2 aimed to determine how long the beneficial impact of the SAI© on witnesses' long-term memory lasts. Participants watched a crime video and then either completed the SAI© or did not engage in an immediate recall attempt. Participants then completed a final recall questionnaire after a delay of 24 h, 1 week, 2 weeks, or 1 month. The results indicated that initial recall should be completed within 24 h of an incident and that under these conditions, the beneficial impact of early recall on long-term memory endures for at least 1 month.

Adult memory for instances of a repeated emotionally stressful event: does retention interval matter?

This pre-registered study examined the impact of different retention intervals on remembering each instance of an emotionally stressful, repeated event. Eighty-nine adult female participants imagined being a victim of four similar domestic violence instances over a four-week period. Participants then completed recall and recognition memory questions about each instance either immediately, one-week, or three-weeks after the final instance. Overall, the findings showed that memory performance was often most accurate for the first and last instance compared to the middle instances. That is, participants reported more correct information, made fewer memory errors, and had better quality memory reports for the first and last instances compared to the middle instances. However, following a short delay (i.e., no delay and one-week), participants reported more correct information and were better at discriminating between correct and false details for the last instance relative to the others instances, while at a longer delay (i.e., three-weeks), more correct information was recalled for the first instance compared to other instances (there was no effect for memory discrimination). These findings suggest that memory for instances of a repeated event can depend on the position of an instance, and under some circumstances, the retention interval.

Proactively providing contraception to New Zealand adolescents.

High adolescent pregnancy rates in New Zealand (NZ) are influenced by limited access to contraception. In this paper, we discuss using a proactive contraception provision (PCP) model to overcome barriers that prevent effective contraceptive uptake. After outlining steps taken to assess acceptability of PCP in NZ, we cover three issues to consider with PCP: the range of contraceptives that should be offered, the age range that should be approached, and finally whether to include adolescents without uteruses. We conclude that PCP is an approach worth considering in the NZ context and should be piloted to assess feasibility and effectiveness.

Stopping crime? The effect of crime re-enactments on eyewitness memory.

Crime re-enactments broadcast on television encourage witnesses to provide information regarding unsolved crimes. However, given that eyewitness memory can be altered through exposure to post-event information, it is possible that crime re-enactments may influence the memory of eyewitnesses. The current studies examined the effects of crime re-enactments on eyewitness memory. In two experiments (Experiment 1 with a distractor task, Experiment 2 without a distractor task), participants were shown one of three versions of a crime video that differed in their ambiguity. One week later half of the participants viewed a crime re-enactment. All participants then completed a guided free- and cued-recall task regarding the original event. Across both studies, exposure to the re-enactment did not improve eyewitness memory; instead, participants who viewed the re-enactment were more likely to accept the misinformation in the re-enactment. The findings shed light on potential issues with using crime re-enactments to elicit eyewitness accounts.

Adult memory for specific instances of a repeated event: a preliminary review.

In cases of repeated victimisation, a complainant's statement of abuse, and therefore memory, is often critical evidence for forensic investigations and legal proceedings. It is therefore important to understand the functioning of adults' memory for repeated events. As such, the purpose of this paper was to review the extant literature on adult memory for instances of a repeated event. The results of the review revealed a small number of heterogeneous studies on adult repeated-event memory (N = 12). The literature so far shows that while adults might have difficulty in recalling information specific to instances (narrow accuracy), they are capable of remembering information across multiple instances (broad accuracy). It was also found that several factors may impact recall of instances including age, the number of experienced instances, rehearsing an event, repeated retrieval and event distinctiveness. The discussion highlights the forensic implications of this research and future research directions.

Using a citizens' jury approach to determine a good nutrition resource for pregnant women.

OBJECTIVE: The development of user-friendly nutrition resources for pregnant women seldom involves end-users. This qualitative study used a citizens' jury approach to determine if our modification of a longstanding, frequently used dietitian-informed diet and diabetes booklet was deemed to be a good healthy eating resource for pregnant women. DESIGN: Midwives recruited thirteen first-time pregnant women not requiring specialist obstetric care or specialist dietetic advice for any reason. Participants were sent a copy of the modified healthy eating in pregnancy booklet prior to 'jury day'. Five women were unable to attend the citizens' jury citing reasons such as early labour. At the jury, five experts presented evidence. Participants adjourned, with an independent facilitator, to 'deliberate' as to whether the resource was suitable or not. The verdict was presented, and subsequent discussion was audio-recorded, transcribed and inductively content analysed. SETTING: Southland, New Zealand. PARTICIPANTS: Pregnant women aged 19-35 years (n 8), of whom half had a household income <$NZ30 000. RESULTS: The verdict was 'Yes'; the resource was good. Three themes were derived: communication of health information, resource content and harm reduction in pregnancy. Based on these data, ways to enhance the quality and usability of the booklet were evident. CONCLUSIONS: Citizens' juries can be used to obtain an independent assessment by end-users of health resources. Our modified diet and diabetes booklet was considered suitable for providing healthy eating advice to pregnant women. Inclusion of end-users' perspectives is critical for end-user relevant content, comprehension and resource credibility.

A survey of the views and practices of abortion of the New Zealand Fellows and trainees of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

BACKGROUND: Abortion is a common procedure in New Zealand (NZ). Currently, it is only legal when two certifying consultants agree that the person seeking an abortion meets the statutory grounds outlined in Section 187A of the NZ Crimes Act (1961). The Crimes Act also states that one-half of certifying consultants must be practising obstetricians/gynaecologists. However, with abortion law reform on the political agenda, the way that abortion services are provided in NZ may change. AIM: This survey of NZ Fellows and trainees evaluates their attitudes toward training requirements for abortion, abortion care provision, and conscientious objection. MATERIALS AND METHODS: A pre-validated questionnaire was sent electronically to all NZ trainees and Fellows. Quantitative data were analysed using descriptive statistics and qualitative data analysed using generalised inductive thematic analysis. RESULTS: Most respondents (95.9%) believe that abortion should be available and 46.8% of respondents either provide abortion, or counsel women about their options and refer. The majority of respondents (73%) support abortion training in FRANZCOG and 68.5% support training in DRANZCOG. Qualitative data reflect a range of views on abortion, the role of conscientious objection in abortion care, and gestational limits. CONCLUSION: This study identifies overall support for abortion provision in NZ and abortion training. However, there is a range of views and practices of abortion among RANZCOG trainees and Fellows that reflects the complexity of the abortion debate.

The effects of repeatedly recalling a traumatic event on eyewitness memory and suggestibility.

The aims of this study were to examine the effects of repeatedly recalling a traumatic event on recall performance and eyewitness suggestibility. We also investigated whether these effects were moderated by the type of details recalled and the completeness of retrieval. Participants watched a video depicting a fatal car accident and were randomly allocated to one of four conditions in which they: (1) repeatedly recalled the traumatic (central) details of the event only (trauma-focused); (2) repeatedly recalled the non-traumatic (peripheral) details of the event only (non-trauma focused); (3) repeatedly recalled the entire video (complete); or (4) did not recall the video at all (no-recall control). Results indicated that repeated complete recall was beneficial for memory retention of the entire traumatic event and that, in general, trauma-related (central) post-event information (PEI) was less likely to be reported than trauma-unrelated (peripheral) PEI. It was also found that repeated trauma-focused recall increased trauma-related confabulations. These results not only illustrate the value of repeated complete recall to best preserve the integrity of eyewitness memory, but, perhaps more critically, warn of the dangers of repeatedly questioning witnesses specifically about the central or traumatic details of an event.

Seasonal and gestational variation in perinatal depression in a prospective cohort in New Zealand.

BACKGROUND: Perinatal depression has wide-ranging impacts on the health of mothers, babies and their families. Previously published data suggest seasonal variation in the prevalence of perinatal depression, as well as possible variation with gestation. AIMS: To describe the prevalence of perinatal depression in a New Zealand population; to describe the trend in depression over gestational age; and to assess the influence of season on perinatal depression. MATERIALS AND METHODS: We performed a secondary analysis of data from a prospective cohort of 260 women in Dunedin, New Zealand. Edinburgh Depression Scores were collected at four antenatal time points and at six months postpartum. RESULTS: Prevalence of depression decreased from 8.1% to 4.6% antenatally, and to 6.6% postnatally, but the variation was non-significant. Prevalence was significantly higher in winter and spring antenatally (odds ratio (OR) 3.15, 95% CI 1.01-9.82 and OR 3.16, CI 1.05-9.55), and in spring postnatally (OR 8.40, 95% CI 1.01-69.52) compared to autumn. Antenatal depression was associated with poor sleep quality (OR 4.27, 95% CI 1.22-14.93), while postnatal depression was associated with caesarean delivery (OR 5.03, 95% CI 1.29-19.64). CONCLUSIONS: This is the first NZ cohort to assess depression over multiple antenatal and postnatal time points. A significantly higher rate of depression was identified in winter and spring antenatally and in spring postnatally, corresponding to a higher risk of postnatal depression with autumn deliveries. These findings should prompt greater awareness at these higher risk time periods.
