Abstract
INTRODUCTION Dysmenorrhea is the most common cause of gynecological pain among women that has considerable impact on quality of life and psychosocial wellbeing. Non-steroidal anti-inflammatory drugs (NSAIDs) and hormonal therapies are most commonly used to treat dysmenorrhea. However, given these drugs are often associated with bothersome side effects and are less effective when there is an underlying cause contributing to dysmenorrhea (e.g. endometriosis), a patient-centered approach to managing dysmenorrhea is important. Various new drugs are currently being investigated for the treatment of primary and secondary dysmenorrhea. AREAS COVERED This review provides an updated overview on new therapeutic targets and investigational drugs for the treatment of primary and secondary dysmenorrhea. The authors describe the clinical development and implications of these drugs. EXPERT OPINION Among the investigative drugs discussed in this review, anti-inflammatories show the most promising results for the treatment of dysmenorrhea. However, given some trials have considerable methodological limitations, many drugs cannot be currently recommended. Research focused on understanding the mechanisms involved in menstruation and its associated symptoms will be important to identify new therapeutic targets for dysmenorrhea. Further robust clinical trials are required to better understand the efficacy and safety of investigational drugs for treating primary and secondary dysmenorrhea.

Abstract
BACKGROUND The incidence of endometrial cancer is globally increasing. Aotearoa New Zealand is no exception with a 59% increase in cases over that last ten years. AIMS We report a sub-set of themes which pertain to provider reflections of rising endometrioid-type endometrial cancer incidence in individuals with high weight. MATERIALS AND METHODS Fifteen semi-structured interviews with healthcare professionals experienced in providing care to women with endometrial cancer were audio-recorded and transcribed. Interviews were analysed using reflexive thematic analysis. RESULTS Two main themes emerged: (1) concerns for the future; and (2) impact on fertility and treatment options. Healthcare professionals discussed rising incidence in younger people and a need for increased awareness about the association of excess weight as a risk factor for developing the disease. The concern extended to workforce and equipment shortfalls of meeting the needs of individuals with higher weight, which subsequently influenced treatment options, health outcomes and survivorship. CONCLUSIONS Rising incidence of endometrial cancer in individuals with high weight presents multiple chances for inequitable access and health outcomes over the care continuum for endometrial cancer. Action is required to address incidence, awareness, access to equitable and inclusive treatment, and survivorship.

Abstract
A reliable non-invasive biomarker for endometriosis is highly likely in the coming years. In the lead-up to this, clinicians need to be aware of commercially available tests as they become accessible, be aware of the level of evidence to support them and be prepared to counsel and manage patients who present with the results of such tests. One such test gaining popularity in Europe was developed using a machine-based learning algorithm to analyse thousands of microRNAs based on a 200-patient cohort with suspected endometriosis in France. We explore the background science for this commercially available test; outline the questions that remain to be answered; and caution against its use outside of a research setting.

Abstract
PURPOSE This pilot study aimed to investigate the acceptability and efficacy of a patient storytelling intervention (live and recorded) on empathy levels of medical students. MATERIALS AND METHODS Medical students participated in a storytelling intervention that had three components: listening to live or recorded stories from women with abnormal uterine bleeding, reflective writing, and a debriefing session. Empathy scores of students pre- and post-intervention were measured using the Jefferson Scale of Empathy-student version (JSE-S). Students also completed a feedback survey. Descriptive and inferential statistics were used to analyse quantitative data and content analysis was used for text comments. RESULTS Both live and recorded storytelling interventions had positive effects on student's empathy scores post intervention. Overall, students were satisfied with the intervention and reported that it improved their understanding of life experiences of women. Suggestions were made for an in-person storytelling session and interactive discussion after listening to each story. CONCLUSION A storytelling intervention has the potential to improve medical students' empathy and understanding of lived experience of women with health conditions. This could be valuable when student-patient interactions are limited in healthcare settings, or to enable stories of small numbers of patient volunteers to reach students.

Abstract
AIMS The aim of this study was to explore barriers and facilitators to delivery and uptake of nutrition advice to women diagnosed with endometrial cancer from a health professionals' viewpoint. METHODS Fifteen semi-structured interviews with health professionals with experience in providing healthcare to women diagnosed with endometrial cancer were audio-recorded and transcribed. Interviews were analysed using reflexive thematic analysis. Topics included high weight as a risk factor for endometrial cancer, nutrition information sources, and barriers and facilitators to delivering nutrition advice in clinical care. RESULTS Four themes were identified. The first three exist as barriers to women receiving nutrition advice-how to navigate conversations about high weight, access to limited resourcing and health professionals feeling powerless to overcome system influences. The fourth theme identified a community approach need to facilitate a supportive environment and share knowledge. CONCLUSIONS This study, through the lens of health professionals, highlights barriers to the delivery and uptake of nutrition advice at the patient, community and system levels. Enhancing survivorship for women after the diagnosis of endometrial cancer may be enabled by further understanding of how to overcome barriers and promote facilitators. Communication and partnership with women are imperative to achieving this.

Abstract
The symptom of heavy menstrual bleeding (HMB) affects at least a quarter of reproductive-age menstruators. However, given the variance in diagnosing the underlying causes, barriers, and inequity in access to care for HMB, and therefore reporting of HMB, this figure is likely to be a gross underestimate. HMB can have a detrimental impact on quality of life. From the limited reports available it is estimated that around 50%-80% of people with HMB do not seek care for this debilitating symptom, and for those that do, it may take years until the first treatment action. Almost half of those with HMB believe their condition is unworthy of treatment, that there is no treatment available, or that it is "normal". The term "medical gaslighting" has recently been used to describe how healthcare professionals disregard people's symptoms. This has the ensuing effect of negatively compounding self-doubt and embarrassment around menstrual bleeding, creating a cycle of diminished experience inhibiting further seeking of care. There is a scarcity of intervention studies informing increased access to care. Multilevel approaches are needed to increase access to care and support for those with HMB. During the COVID-19 global pandemic, barriers to care access and support for HMB have been exacerbated and, given the significant pressures that this pandemic has placed on healthcare services worldwide, it will take many years to recover. In the meantime, it is crucial to ensure that medically "benign" conditions such as the symptom of HMB are not overlooked.

Abstract
BACKGROUND Since 2015, the Ambitions for Palliative and End of Life Care: a national framework for local action has provided guidance for care within England and beyond. Relaunched in 2021, the Framework sets out six Ambitions which, collectively, provide a vision to improve how death, dying and bereavement are experienced and managed. However, to date, there has been no central evaluation of how the Framework and its Ambitions have been implemented within service development and provision. To address this evidence gap, we investigated understanding and use of the Framework. METHODS An online questionnaire survey was conducted to identify where the Framework has been used; examples of how it has been used; which Ambitions are being addressed; which foundations are being used; understanding of the utility of the Framework; and understanding of the opportunities and challenges involved in its use. The survey was open between 30 November 2021-31 January 2022, promoted via email, social media, professional newsletter and snowball sampling. Survey responses were analysed both descriptively, using frequency and cross-tabulations, and exploratively, using content and thematic analysis. RESULTS 45 respondents submitted data; 86% were from England. Findings indicate that the Framework is particularly relevant to service commissioning and development across wider palliative and end of life care, with most respondents reporting a focus on Ambition 1 (Each person is seen as an individual) and Ambition 3 (Maximising comfort and wellbeing). Ambition 6 (Each community is prepared to help) was least likely to be prioritised, despite people welcoming the focus on community in national guidance. Of the Framework foundations, 'Education and training' was seen as most necessary to develop and/or sustain reported services. The provision of a shared language and collaborative work across sectors and partners were also deemed important. However, there is some indication that the Framework must give more prioritisation to carer and/or bereavement support, have greater scope to enhance shared practice and mutual learning, and be more easily accessible to non-NHS partners. CONCLUSIONS The survey generated valuable summary level evidence on uptake of the Framework across England, offering important insights into current and past work, the factors impacting on this work and the implications for future development of the Framework. Our findings suggest considerable positive potential of the Framework to generate local action as intended, although difficulties remain concerning the mechanisms and resources necessary to enact this action. They also offer a valuable steer for research to further understand the issues raised, as well as scope for additional policy and implementation activity.

Abstract
Endometrial cancer (EC) is the most common gynecologic malignancy in the world and incidence is steadily increasing. The Levonorgestrel Intrauterine System (LNG-IUS) is an alternative conservative treatment for early-stage EC, however, Levonorgestrel (LNG) resistance occurs for 1 in 3 people. This study aimed to present potential LNG resistance mechanisms and identify differentially expressed genes (DEGs) in EC cell lines. Two LNG resistant cell lines were developed through long term culture in LNG (MFE296R and MFE319R ). Whole transcriptome sequencing was carried out on triplicate RNA samples. EdgeR v3.32.1 was used to identify differentially DEGs. Blast2go V6.0 (BioBam software) was used for functional annotation and analysis of genomic datasets. Protein interactions were investigated using the STRING database, including the identification of genes with high levels of interaction (HUB genes). Select DEGs and HUB genes were validated by quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. Fifteen DEGs were identified according to FDR < 0.05 and logFC < 2. Protein analysis identified six HUB genes with a degree of connectivity > 10. Relative mRNA expression of MAOA, MAOB, THRSP, CD80, NDP, LINC01474, DUSP2 and CXCL8 was significantly upregulated in both LNGR cell lines. Relative protein expression of GNAO1 and MAOA were significantly upregulated in both LNGR cell lines. This research identified novel markers of resistance in LNGR cell lines. We discussed potential mechanisms of LNG resistance including dedifferentiation and immunostimulation. The next step for this research is to validate these findings further in both translational and clinical settings.

Abstract
Differences of sex development (DSDs) are a group of congenital conditions characterized by a discrepancy between chromosomal, gonadal, and genital sex development of an individual, with significant impact on medical, psychological and reproductive life. The genetic heterogeneity of DSDs complicates the diagnosis and almost half of the patients remains undiagnosed. In this context, chromosomal imbalances in syndromic DSD patients may help to identify new genes implicated in DSDs. In this study, we aimed at describing the burden of chromosomal imbalances including submicroscopic ones (copy number variants or CNVs) in a cohort of prenatal syndromic DSD patients, and review their role in DSDs. Our patients carried at least one pathogenic or likely pathogenic chromosomal imbalance/CNV or low-level mosaicism for aneuploidy. Almost half of the cases resulted from an unbalanced chromosomal rearrangement. Chromosome 9p/q, 4p/q, 3q and 11q anomalies were more frequently observed. Review of the literature confirmed the causative role of CNVs in DSDs, either in disruption of known DSD-causing genes (SOX9, NR0B1, NR5A1, AR, ATRX, …) or as a tool to suspect new genes in DSDs (HOXD cluster, ADCY2, EMX2, CAMK1D, …). Recurrent CNVs of regulatory elements without coding sequence content (i.e. duplications/deletions upstream of SOX3 or SOX9) confirm detection of CNVs as a mean to explore our non-coding genome. Thus, CNV detection remains a powerful tool to explore undiagnosed DSDs, either through routine techniques or through emerging technologies such as long-read whole genome sequencing or optical genome mapping.

Abstract
BACKGROUND Women with abnormal uterine bleeding (AUB) experience barriers to accessing healthcare services. OBJECTIVES To identify and describe the evidence on interventions to improve healthcare access of women with AUB. SEARCH STRATEGY A systematic search of databases including Medline, CINAHL, EMBASE, Scopus, and Cochrane register for clinical trials on February 26, 2021. SELECTION CRITERIA Studies including women with AUB and investigating an intervention to improve access at the levels of individual patient, community, organization, health system, or medical education. DATA COLLECTION AND ANALYSIS Data extraction and descriptive analysis of the country, study design, settings, participant characteristics, intervention, outcome measures, and key findings. MAIN RESULTS We identified 20 studies and most interventions (13 studies) targeted organizational changes. Creating a multidisciplinary team, bringing services together and developing a care pathway improved the availability of services. Management of AUB in an outpatient setting improved the affordability. The use of decision aids improved patient engagement in consultations. There is a lack of interventions at an individual or community level targeting health literacy, health beliefs, social acceptability, and opportunity to reach and pay for services. CONCLUSIONS Community-based culturally-adapted interventions focusing on access to women with different socio-economic and cultural backgrounds should be investigated.

Abstract
In orthopedic surgery, the well-known iatrogenic risk of oral anticoagulants is particularly increased due to surgical management (suspension and resumption of treatment). In order to prevent avoidable iatrogenic events linked to incomplete discharge documents, targeted medical reconciliation (MR) has been deployed. This is a single-center prospective study conducted in orthopaedic surgery for six months including any patient treated upon admission with an oral anticoagulant. The analysis of the compliance of discharge documents (hospitalization report and prescriptions) was carried out before and after pharmaceutical interventions. The criteria analysed included the mention of the oral treatment, its dosage as well as the supervision of the switch from heparin therapy to the usual oral treatment. The documents were compliant if the mention of oral anticoagulant treatment and the date of the shift were correctly documented. Thirty-seven patients were included. The compliance rate of discharge documents was significantly improved by MR, going from 13.5 % to 78.4 % (P <0.05). The non-compliances before the intervention concerned the absence of mention of: the usual treatment (64.9 %), its dosage (81.1 %) or the switch's securing (75.7 %). Discharge from surgery of the patient on anticoagulants is a stage presenting a real risk which can be managed by the intervention of pharmacists. Improving the compliance of discharge documents is a first step towards better securing drug management.

Abstract
Abstract
Introduction
Multiple smart devices capable of “screening” for atrial fibrillation (AF) based on single-lead electrocardiogram (SL ECG) are presently available. Manufacturers' algorithm capabilities and accuracy for the automated detection of AF vary. Reliable artificial intelligence (AI) algorithms would be valuable to assist physicians with managing the large amount of data. We aimed to assess the clinical value of applying a smart device agnostic AI-based algorithm for the detection of AF from five different smart devices (four smartwatches, one handheld device) and compared the results to the cardiologist-interpreted 12-lead ECG in a real world cohort of patients.
Methods
This is a prospective, observational study enrolling patients presenting to a cardiology service at a tertiary referral center. Patients were prescribed a 12-lead ECG, followed by five consecutive smart device recordings from five different manufacturers. SL ECGs were exported as PDF files from the devices and analyzed by a deep neural network (DNN) based platform which allows automated AI assisted cardiac rhythm interpretation.
Results
We prospectively enrolled 157 patients (32% female, median age 66 years). AF was present in 48 patients (31%) at time of recording, as documented by the 12-lead ECG. Accuracy for the detection of AF by the DNN-based algorithm was 96.6% for the Apple Watch 6, 95.2% for the AliveCor Kardia Mobile, 96.0% for the Fitbit Sense, 95.7% for the Samsung Galaxy Watch 3 and 93.8% for the Withings Scanwatch, respectively (Figure 1, left). While diagnostic accuracy of the DNN-based algorithm was similar compared to each manufacturer's individual algorithm, the proportion of SL ECGs with a conclusive diagnosis was significantly higher for all smart devices when using the DNN-based algorithm, p<0.001 (Figure 1, right). As complementary analysis, we assessed sensitivity and specificity detection capabilities in both algorithms (Figure 2).
Conclusion
In this clinical validation, a DNN-based algorithm reported significantly more conclusive diagnoses for each smart device compared to the manufacturers' algorithms, whilst showing similarly high accuracy in the detection of AF compared to the cardiologist-interpreted standard 12-lead ECG. Given further validation, SL ECG assisted rhythm interpretation through a cross-platform AI-algorithm presents a promising clinical value for AF detection and offers a possible solution for managing the data surge for smart device-acquired ECGs.

Abstract
Human brain development is a complex process that begins in the third week of gestation. During early development, the fetal brain undergoes dynamic morphological changes. These changes result from events such as neurogenesis, neuronal migration, synapse formation, axonal growth and myelination. Disruption of any of these processes is thought to be responsible for a wide array of different pathologies. Recent advances in magnetic resonance imaging, especially diffusion-weighted imaging and diffusion tensor imaging (DTI), have enabled characterization and evaluation of brain development in utero. In this review, aimed at practitioners involved in fetal medicine and high-risk pregnancies, we provide a comprehensive overview of fetal DTI studies focusing on characterization of early normal brain development as well as evaluation of brain pathology in utero. We also discuss the reliability and limitations of fetal brain DTI. © 2022 International Society of Ultrasound in Obstetrics and Gynecology.

Abstract
Endometrial cancer (EC) is the most common gynaecological malignancy in the developed world, and concerningly incidence is rising, particularly in younger people. Therefore, there is increased interest in novel diagnostic and prognostic biomarkers. Extracellular vesicles (EVs) are membrane-bound particles present in bodily fluids that have the potential to facilitate non-invasive, early diagnosis of EC and could aid with monitoring of recurrence and treatment response. EV cargo provides molecular insight into the tumor, with the lipid bilayer providing stability for RNA species usually prone to degradation. miRNAs have recently become a focus for EV biomarker research due to their ability to regulate cancer related pathways and influence cancer development and progression. This review evaluates the current literature on EV miRNA biomarkers with a focus on EC, and discusses the challenges facing this research. This review finally highlights areas of focus for EV miRNA biomarker research going forward, such as standardization of normalization approaches, sample storage and processing, extensive reporting of methodologies and moving away from single miRNA biomarkers.

Abstract
The Covid‐19 vaccine has been recommended for pregnant people (hapū māmā) in Aotearoa New Zealand since June 2021. We surveyed people birthing in a tertiary hospital regarding their vaccination status and reasons for this. There were 74% (142/191) of pregnant people who were fully vaccinated. Motivators for vaccination included protection against Covid‐19 and antibody transfer to the baby (pēpē). Unvaccinated participants worried about vaccine safety. Concerns were raised about the change in official advice without well‐communicated reasons for the change. Future vaccine and booster rollouts must be delivered equitably and hapū māmā must be a priority group.

Abstract
Introduction
Bipolar disorder has been repeatedly associated with abnormalities of white matter. However, DTI is intrinsically limited and the precise cellular mechanisms that underlie these alterations remains unknown.
Objectives
Our aim was to investigate microscopical characteristics of white matter using MRI in patients with bipolar and healthy controls.
Methods
77 patients and 71 controls from 3 sites had a T1 structural MRI, a multi-shell HARDI MRI and at one site with a T1-weighted VFA-SPGR acquisition, and a T2 MSME acquisition. The volume fraction and the orientation dispersion was extracted using NODDI from DW images in each site. Myelin Water Fraction was extracted in 33 patients and 36 controls to probe myelin characteristics. White matter bundles were reconstructed using deterministic tractography. Statistical analyses were performed after harmonization by the ComBat algorithm and controlled for age, gender and handedness.
Results
We found significant lower axonal density in patients along the short fibers of the left cingulum, the left anterior arcuate and the left inferior fronto-occipital fasciculus. We found lower mean MWF in patients along the short fibers of the right cingulum, the left inferior fronto-occipital fasciculus, the left anterior arcuate and the splenium of the corpus callosum. We found higher mean orientation dispersion in patients only along the left uncinate fasciculus.
Conclusions
We report alterations of limbic and inter-hemispheric white matter tracts in patients with bipolar disorder reflecting axonal loss, demyelination and architecture alterations. These results contribute to better capture the plurality of the mechanisms involved in bipolar disorder that cannot be deciphered with classical diffusion MRI.

Abstract
Introduction Bipolar disorder (BD) is a psychiatric disorder characterized by alternating episodes of high mood and low mood similar to depression. To differentiate BD patients from unipolar (UN) depressed patients remains a challenge and the clinical scales available failed to distinguish these 2 populations. ALCEDIAG developed EDIT-B, the first blood test able to make a differential diagnosis of BD. Based on RNA editing modifications measurement and AI, the test requires a simple blood draw and equipment available in most central laboratories. A first study on 160 UN and 95 BD patients allowed a differential diagnosis with an AUC of 0.935 and high specificity (Sp=84.6%) and sensitivity (Se=90.9%). A multicentric clinical study has been set up to validate these performances. Objectives The objective of this project is to run a multicentric clinical study in Europe and assess the performances of the test. Methods The EDIT-B project, led by Alcediag, is supported by EIT-Health grant (European institute of Innovation and Technology) and gathers 4 clinical centers in 3 countries (France, Spain, Danemark), a CRO for the clinical study management (Aixial), a CRO for the development of a diagnostic kit (Veracyte), a diagnostic lab for molecular biology analyses (Synlab), and a regulatory company (PLG). Results At the end of the study, the EDIT-B performance will be confirmed and the test will be CE-marked. Conclusions This test will address the needs of millions of patients suffering from misdiagnosis and therefore allow them to receive the correct treatment. Disclosure JDA, NS and DW are employees of Alcediag.

Background/Introduction
Smartwatch electrocardiograms (SW ECG) have been identified as a promising noninvasive solution to assess heart rhythm abnormalities, especially atrial arrhythmias (AA) which includes atrial fibrillation, atrial flutter and supraventricular tachycardia. This study evaluates the performance of the detection of AA with a smartwatch and compares the accuracy of two algorithms, the latest version of the original companion application (Apple ECG 2.0 App) and a novel deep neural network (DNN), in a population typical of an electrophysiology department.
Purpose
Determine if a novel DNN can improve the detection of AA on SW ECG in a tertiary care hospital.
Methods
101 patients from the electrophysiology department of one tertiary center were included in this ongoing study. Three simultaneous ECGs were collected for each patient: one 12-lead ECG (Mindray BeneHeart R12) and two SW ECGs (Apple Watch) taken from the left wrist (SWw ECG) and the lower left abdomen (SWa ECG). 12-lead ECGs were adjudicated by a blinded expert electrophysiologist as 52 AA and 49 not AA and considered as gold standard. The SW ECGs were processed by the ECG 2.0 App and the DNN in parallel. The proportions of inconclusive diagnoses returned and the performances were assessed and compared.
Results
Overall, the ECG 2.0 App yielded inconclusive diagnoses for 19% (19/101) of all SWw ECGs while the DNN reduced that number to 0% (0/101). A similar result holds for SWa ECGs (Figure 1). Regarding the detection of AA from SWw ECGs, the ECG 2.0 App had a sensitivity of 81% (95% CI, 67%-90%), a specificity of 97% (95% CI, 87%-100%) and an accuracy of 89% (95% CI, 80%-94%) while the DNN had a sensitivity of 92% (95% CI, 82%-97%), a specificity of 90% (95% CI, 78%-96%) and an accuracy of 91% (95% CI, 84%-95%). For SWa ECGs (Figure 2), the sensitivity of the DNN was found significantly higher compared to the ECG 2.0 App: 96% (95% CI, 89%-98%) vs 76% (95% CI, 61%-87%). Conclusion(s): A novel DNN algorithm decreased the number of inconclusive diagnostics in the detection of AA from SW ECG from around 20% to 0%, which could help limit the overreading time spent by the physicians. Excluding inconclusive diagnostics, we observed no significant difference in performance between the two algorithms except for the sensitivity for SW ECG taken from the abdomen where the DNN outperforms the ECG 2.0 App. Routine application of this SW ECG analysis in tertiary care hospitals offers significant promise in arrhythmia diagnosis.

Abstract
INTRODUCTION Aspirin overdose causes acid-base disturbances and organ dysfunction. Management is guided by research reported over 50 years ago when chronic aspirin toxicity was common and accounted for significant morbidity. We investigate our experience of aspirin overdose and the effectiveness of charcoal and bicarbonate administration over 20 years. METHODS This is a retrospective series of acute aspirin overdose from two toxicology units from January 2000 to September 2019. Acute aspirin ingestions > 3000 mg were identified in each unit's database. Excluded were cases of chronic exposure, hospital presentation > 24 hours after ingestion, and cases without a salicylate concentration. Included in our analysis was demographic data, clinical effects, investigations, complications, and treatment. RESULTS There were 132 presentations in 108 patients (79 females (73%)). The median age was 28 years (range: 13-93 years). The median dose ingested was 7750 mg (IQR: 6000-14,400 mg). There were 44 aspirin-only ingestions. Mild toxicity (nausea, vomiting, tinnitus or hyperventilation) occurred in 22 with a median dose of 160 mg/kg. Moderate toxicity (acid-base disturbance, confusion) occurred in 16 with a median ingested dose of 297 mg/kg. There were no cases of severe toxicity (coma or seizures) due to aspirin alone. The median peak salicylate concentration was 276 mg/L (IQR: 175-400 mg/L, range: 14-814 mg/L). There was a moderate association between dose ingested and peak concentration (Pearson r = 0.58; 95% CI 0.45-0.68). Activated charcoal was administered in 36 (27%) cases, which decreased the median peak salicylate concentration (34.2 to 24.8 mg/L/g (difference: 9.4, 95% CI: 1.0-13.1)). Bicarbonate was administered in 34 (26%) presentations, decreasing the median apparent elimination half-life from 13.4 to 9.3 h (difference: 4.2 h, 95% CI: 1.0-6.5 h). CONCLUSIONS Acute aspirin overdose caused only mild to moderate effects in this series. Early administration of activated charcoal decreased absorption and use of bicarbonate enhanced elimination.

CONTEXT In 2007, we performed a nationwide prospective study to assess the epidemiology of encephalitis in France. We aimed to evaluate epidemiological changes 10years later. METHODS We performed a 4-year prospective cohort study in France (ENCEIF) from 2016 to 2019. Medical history, comorbidities, as well as clinical, biological, imaging, and demographic data were collected. For the comparison analysis, we selected similar data from adult patients enrolled in the 2007 study. We used Stata statistical software, version 15 (Stata Corp). Indicative variable distributions were compared using Pearson's Chi2 test, and means were compared using Student's t-test for continuous variables. RESULTS We analyzed 494 cases from 62 hospitals. A causative agent was identified in 65.7% of cases. Viruses represented 81.8% of causative agents, Herpesviridae being the most frequent (63.6%). Arboviruses accounted for 10.8%. Bacteria and parasites were responsible for respectively 14.8% and 1.2% of documented cases. Zoonotic infections represented 21% of cases. When comparing ENCEIF with the 2007 cohort (222 adults patients from 59 hospitals), a higher proportion of etiologies were obtained in 2016-2019 (66% vs. 53%). Between 2007 and 2016-2019, the proportions of Herpes simplex virus and Listeria encephalitis cases remained similar, but the proportion of tuberculosis cases decreased (P=0.0001), while tick-borne encephalitis virus (P=0.01) and VZV cases (P=0.03) increased. In the 2016-2019 study, 32 causative agents were identified, whereas only 17 were identified in the 2007 study. CONCLUSION Our results emphasize the need to regularly perform such studies to monitor the evolution of infectious encephalitis and to adapt guidelines.

Abstract
Background Endometrial cancer (EC) is the most common gynaecologic malignancy in the developed world, and incidence is increasing in premenopausal women. The levonorgestrel intrauterine system (LNG-IUS) is gaining traction as an alternative treatment for hyperplasia and early-stage EC for women who are unable to undergo surgery. Thirty to 60% of the women do not respond to this treatment, making the unknown mechanisms of levonorgestrel (LNG) resistance a critical obstacle for the conservative management of EC. This study aimed to characterise LNG-IUS treatment resistance in early-stage endometrial cancer in cell-line models. Methods LNG-resistant endometrial cancer cell lines (MFE296R and MFE319R) and cultures from three early stage endometrial cancer patients were developed. The behavioural profile of MFE296R and MFE319R was analysed using proliferation, adhesion, migration (wound healing and transwell) and invasion (spheroid) assays. LNG-sensitive cell lines (MFE296S and MFE319S) were compared to LNGR cell lines (MFE296R and MFE319R). A literature search was conducted to identify possible candidate biomarkers of LNG resistance. RT-qPCR was used to analyse the mRNA expression of 17 candidate biomarkers in MFE296R and MFE319R. mRNA expression of the top differentially expressed genes was measured using RT-qPCR in primary cultures. Results LNG resistance did not affect proliferation or invasion in immortalised endometrial cancer cells. Transwell migration was significantly increased in MFE319R cells (p=0.03). Cellular adhesion significantly decreased in both MFE296R cells (p=0.012) and MFE319R cells (p=0.04). mRNA expression of KLF4 and SATB2 was significantly amplified in MFE296R and MFE319R cells. mRNA expression of KLF4 was significantly upregulated LNG-resistant primary cell lines. Conclusion LNG-resistant cells may have more oncogenic potential than their LNG-sensitive counterparts. Significant changes in the mRNA expression of KLF4 and SATB2 of LNG-resistant cells is a promising preliminary result in biomarker discovery for guiding LNG-IUS treatment of early stage endometrial cancer.

Abstract
Endometrial Cancer (EC) is the most common gynaecologic malignancy in the developed world, and is increasing in premenopausal women. The surgical standard of care for early-stage EC is not possible in women with concurrent comorbidities or women who desire a fertility sparing approach. The Levonorgestrel Intrauterine System (LNG-IUS) is gaining traction as an alternative treatment for endometrial hyperplasia and early stage EC in inoperable women. Whilst early evidence appears promising, predictive biomarkers need to be established to determine non-responders, which make up one in three women. This timely review discusses the current literature around the identification of clinical, molecular and novel biomarkers that show potential to predict response to progesterone treatment, including the LNG-IUS.

Abstract
OBJECTIVES To investigate the experiences and views of practitioners in the UK and Ireland concerning changes in bereavement care during the COVID-19 pandemic. DESIGN Online survey using a snowball sampling approach. SETTING Practitioners working in hospitals, hospices, care homes and community settings across the UK and Ireland. PARTICIPANTS Health and social care professionals involved in bereavement support. INTERVENTIONS Brief online survey distributed widely across health and social care organisations. RESULTS 805 respondents working in hospice, community, and hospital settings across the UK and Ireland completed the survey between 3 August and 4 September 2020. Changes to bereavement care practice were reported in: the use of telephone, video and other forms of remote support (90%); supporting people bereaved from non-COVID conditions (76%), from COVID-19 (65%) and people bereaved before the pandemic (61%); funeral arrangements (61%); identifying bereaved people who might need support (56%); managing complex forms of grief (48%) and access to specialist services (41%). Free-text responses demonstrated the complexities and scale of the impact on health and social care services, practitioners and their relationships with bereaved families, and on bereaved people. CONCLUSIONS The pandemic has created major challenges for the support of bereaved people: increased needs for bereavement care, transition to remote forms of support and the stresses experienced by practitioners, among others. The extent to which services are able to adapt, meet the escalating level of need and help to prevent a 'tsunami of grief' remains to be seen. The pandemic has highlighted the need for bereavement care to be considered an integral part of health and social care provision.

Abstract
Background: The objective of this study was to develop a conceptual framework to define a domain map describing the experience of patients with severe mental illnesses (SMIs) on the quality of mental health care. Methods: This study used an exploratory qualitative approach to examine the subjective experience of adult patients (18-65 years old) with SMIs, including schizophrenia (SZ), bipolar disorder (BD) and major depressive disorder (MDD). Participants were selected using a purposeful sampling method. Semistructured interviews were conducted with 37 psychiatric inpatients and outpatients recruited from the largest public hospital in southeastern France. Transcripts were subjected to an inductive analysis by using two complementary approaches (thematic analysis and computerized text analysis) to identify themes and subthemes. Results: Our analysis generated a conceptual model composed of 7 main themes, ranked from most important to least important as follows: interpersonal relationships, care environment, drug therapy, access and care coordination, respect and dignity, information and psychological care. The interpersonal relationships theme was divided into 3 subthemes: patient-staff relationships, relations with other patients and involvement of family and friends. All themes were spontaneously raised by respondents. Conclusion: This work provides a conceptual framework that will inform the subsequent development of a patient-reported experience measure to monitor and improve the performance of the mental health care system in France. The findings showed that patients with SMIs place an emphasis on the interpersonal component, which is one of the important predictors of therapeutic alliance. Trial registration: NCT02491866.

Abstract
Vaginal evisceration of the small bowel is a surgical emergency insofar as it entails the risk of acute vascular lesions in the latter. It may be caused by a vaginal prolapse. Delayed treatment of a prolapse may entail the risk of poor scarring of vaginal suture, and sacrocolpopexy is not necessarily called for. In an 80-year-old female patient with repeatedly recurrent stage 4 vaginal prolapse, vaginal evisceration and vaginal prolapse were treated by perineal approach and emergency colpocleisis.

Abstract
INTRODUCTION There are few studies of user perceptions of the Levonorgestrel Intrauterine System (LNG-IUS; Mirena™), which now has the potential to play an important role in the treatment of women with hyperplasia or early stage endometrial cancer. There is limited evidence on how well the Mirena™ is perceived and accepted by women in this context. AIM To gain an understanding of New Zealand women's views on the use of the Mirena™ contraceptive device to inform policies in endometrial cancer prevention. METHODS An online survey platform (Qualtrics™) was disseminated over social media sites such as Facebook once a week for 3 weeks. The survey used mixed methods (closed questions, multiple choice and open-ended questions) and covered topics relating to the knowledge and use of the Mirena™ for endometrial protection. Data were collected and explored using content and thematic analysis. RESULTS In total, 89 women responded to the survey. Half (42/89) of respondents had never used a Mirena™ in their life. Most women (79/89) did not know anyone who had had endometrial cancer. The frequency of negative comments about the Mirena™ was higher than positive comments (42 and 26 respectively), largely attributed to personal or reported poor experiences with other contraceptives (including the copper intrauterine device). DISCUSSION Although health-care providers may view the Mirena™ favourably, this view was not reciprocated in this community sample.

Abstract
OBJECTIVE Non-Alcoholic fatty liver disease (NAFLD) is becoming the most common liver disease in Western populations. While obesity and metabolic abnormalities are highly frequent in bipolar disorders (BD), no studies have been performed to estimate the prevalence of NALFD in individuals with BD. The aim of our study is to estimate the prevalence of NAFLD and to identify the potential associated risk factors in a large sample of BD individuals. METHODS Between 2009 and 2019, 1969 BD individuals from the FACE-BD cohort were included. Individuals with liver diseases, Hepatitis B or C, and current alcohol use disorders were excluded from the analyses. A blood sample was drawn from participants. Screening of NAFLD was determined using fatty liver index (FLI). Individuals with FLI> 60 were considered as having NAFLD. RESULTS The prevalence of NAFDL in this sample was estimated at 28.4%. NAFLD was observed in 40% of men and 21% of women. NAFLD was independently associated with older age, male gender, sleep disturbances, and current use of atypical antipsychotics or anxiolytics. As expected, the prevalence of NALFD was also higher in individuals with overweight and in those with metabolic syndrome. CONCLUSIONS This study reinforces the view that individuals with BD are highly vulnerable to metabolic and cardiovascular diseases. The prevalence of NAFLD in individuals with BD was two times higher than the prevalence reported in the general population. The regular screening of the MetS in individuals with BD should be therefore complemented by the additional screening of NAFLD among these vulnerable individuals.

Abstract
OBJECTIVE To gain a deeper understanding of women's experiences of accessing care for abnormal uterine bleeding (AUB) in order to inform future strategies to improve care pathways, including the early detection of endometrial cancer. DESIGN We conducted semistructured interviews with 15 women who attended their first gynaecological specialist consultation for AUB at Wellington Regional Hospital between October and December 2019. Inductive thematic analysis was used to explore experiences and barriers to seeking care. RESULTS The median age of the participant cohort was 45 years, with women self-identifying as New Zealand European (9/15), Māori (2/15) and Pasifika (4/15). All women had sought investigation for their AUB in primary care, for some women this was over a timeframe of many years. For all women, AUB had a significant and traumatic impact on their quality of life including their relationships and their work or education. Women described how they felt they often received inadequate care for AUB, and reported negative experiences with their general practitioner. Timely access was further compounded by feelings of embarrassment and that AUB was a taboo subject, and being able to discuss it with family, friends and their general practitioners was difficult. CONCLUSION Women in our cohort experienced a multitude of compounding influences that acted as barriers to them having access to appropriate and timely care. Information campaigns that create awareness around 'abnormal periods' alongside better health provider practice guidelines for AUB investigation need to be a priority.

Abstract
The necessity of developing effective and innovative primary prevention strategies is a pressing objective in stemming the harm caused by the production and consumption of child sexual exploitation material (CSEM). Digital media interventions - including search engine advertisements - hold promise as prevention tools to deflect potential users away from CSEM and redirect them to therapeutic services. This study aimed to establish an evidence base for effective advertising in this context by creating mock-up helpline advertisements and testing them in focus groups and interviews with staff and clients of New Zealand's major treatment service providers for harmful sexual behavior. Prior to testing these advertisements in situ (on online platforms), this paper reports on a foundational creative and qualitative investigation of effective advertisements - what imagery, text, and design features are most likely to succeed in diverting people away from seeking CSEM and encouraging them to reach out to a helpline? The findings of this study offer deeper understanding of the mindset, emotions, and barriers to reaching out that are experienced by onset CSEM users, as well as suitability of certain imagery and text for advertising in this context, and thereby contribute to strengthening primary prevention efforts in combatting CSEM consumption.

Abstract
BACKGROUND Valproate is associated with teratogenic and neurodevelopmental effects. Several agencies have restricted the conditions of its prescription in bipolar disorders (BD). We aimed to assess the evolution of valproate prescription and the clinical profile of BD women of childbearing age receiving valproate. METHODS Based on a large national cohort, we included all BD women 16-50 years old. Sociodemographic, clinical and pharmacological data were recorded. Logistic regression analyses were used to describe variables associated with valproate prescription. RESULTS Of the 1018 included women 16-50 years old, 26.9% were treated with valproate with a mean daily dosage of 968 mg. The prevalence of BD women using valproate was 32.6% before May 2015 and 17.3% after May 2015 (p<0.001), the date of French regulatory publication of restriction of valproate prescription. The multivariate analysis revealed that the inclusion period after May 2015 (OR=0.54, CI 95% 0.37-0.78, p=0.001), the age lower than 40 years (OR=0.65, CI 95% 0.43-0.98, p=0.040) and the number of lifetime mood episodes (OR=0.98, CI 95% 0.95-0.99, p=0.040) were the variables negatively associated with the use of valproate. LIMITATIONS Study could be underpowered to determine a clinical profile associated with valproate prescription. CONCLUSIONS The regulatory change in BD women of childbearing age had a significant impact on valproate prescription, even if the prescription rate remains high. Important efforts are needed to help clinicians and patients to improve quality of care in BD women of childbearing age.

Abstract
Abstract
Background and aim
Tumor derived cell-free DNA (cfDNA) in blood is a promising biomarker for cancer. Understanding factors that influence cfDNA concentrations and tissues of origins will assist with cancer biomarker development by excluding cfDNA changes driven by normal physiological processes. Endothelial cells make up 10% of the plasma cfDNA pool and undergo angiogenesis in the endometrium during the recurrent cycles of menstruation. Therefore, endothelial cfDNA changes are a potential source of false positive signals in cancer screening of pre-menopausal women. The aim of this study is to determine if cfDNA derived from the endothelium is increased during menstruation.
Methods
80 matched blood samples were collected from 40 healthy female donors at non-menstruating (NM) and menstruating (M) phases. CfDNA was extracted from 5 mL of plasma and quantified by qPCR by targeting a short (ALU115) and long region (ALU247) of ALU sequences. Methylation specific primers were designed to interrogate VE-cadherin DNA region at sequences downstream of the transcriptional start site (from +122 bp to +218 bp) to generate a 96 bp amplicon. The primer was tested against human primary aortic and blood-brain barrier endothelial cells as positive controls. To detect and measure endothelium derived sequences, cfDNA equivalent of 4 mL of plasma was bisulfite converted for quantification of endothelial specific VE-cadherin region by qPCR.
Results
VE-cadherin was identified from the literature and selected as a gene with methylation unique to endothelial cells. The VE-cadherin primer, designed specifically to amplify unmethylated version of the region, was tested against bisulfite-converted human aortic and blood-brain barrier genomic DNA with detection levels down to 111 pg and 125 pg input, respectively.
There was no statistically significant change in total cfDNA amount during menstruation and, based on the ratio of ALU115 and ALU247, no change in the integrity and size distribution of cfDNA was observed. We also found no correlation in total cfDNA amount between the NM and M phases. However, there was a positive correlation in the size ratio (r = 0.53), meaning that while individual cfDNA levels fluctuate over time, the size distribution stays relatively similar. Additionally, no significant changes were observed in the endothelium-derived cfDNA concentration between NM and M phases in the 40 matched plasma, including when the proportion is adjusted against the total cfDNA concentration. Positive correlation was also found between NM and M samples in the endothelium-derived cfDNA levels (r = 0.4).
Conclusion
This absence of change suggests a specific release pathway for cfDNA to enter the bloodstream rather than simply inefficiency in apoptotic debris clean-up and provides evidence that women can be screened for early detection of ovarian cancer using tests targeting cfDNA methylation regardless of their menstrual status.

Abstract
Abstract
Background: Ovarian cancer screening has the potential to greatly reduce mortality by shifting the time of diagnosis to an early stage when the tumor is confined to a single site and can be completely cured by surgical removal. Ovarian cancer DNA is present in blood and has a distinct methylation profile that distinguishes it from healthy blood cells, thus making it a target for ovarian cancer diagnosis via a blood test. However, while the presence of this DNA in the blood of cancer patients is well established, low abundance and DNA fragmentation present a barrier to developing clinical applications that target it.
Methods: We are systematically evaluating and optimizing each step of DNA extraction, processing, and analysis to increase the sensitivity of cancer DNA detection by PCR. At the same time, we are developing PCR assays to detect ovarian cancer specific methylation based on a previous tumor and blood screen that identified 73 methylated candidate biomarker regions.
Results: We have found that inhibitors of the PCR reaction introduced into the sample during DNA extraction and bisulphite treatment limit the total amount of DNA that can be analyzed, and thus the sensitivity of the test. Precipitation of the DNA samples prior to PCR analysis removes the inhibitors and increases useable sample volume and thus sensitivity. We have also developed methylation-specific PCR assays for DNA regions that are methylated in ovarian tumor tissue, and unmethylated in white blood cells.
Conclusions: We are progressing our candidate methylated DNA ovarian cancer biomarkers closer to testing in clinical samples. Our results on sample processing and DNA analysis methods to enable ovarian cancer DNA detection are relevant to all cancer types for which cell-free tumor DNA has clinical applications.

Abstract
Background Although Abnormal Uterine Bleeding (AUB) can have serious medical consequences and significantly impacts daily life, the overall trend is that most women do not seek care for these symptoms. The objective of this review was to synthesise factors impeding women’s access care for AUB. Methods Systematic literature review of qualitative studies (interview and focus group) regarding the lived in experiences of women with abnormal menstrual symptoms, followed by a thematic analysis of these studies. We screened CINAHL, SCOPUS, ProQuest, OVID and Pubmed for qualitative studies. Studies were assessed using the Clinical Appraisal Skills Programme checklist and thematic synthesis was used to develop themes from the findings of the studies. Results The review yielded 12 studies that satisfied the inclusion criteria. Three themes were developed that described barriers for women seeking care for AUB: health literacy (understanding of normal periods, role of cervical Pap smears and lack of access to appropriate information), taboo/normalisation (fear and embarrassment of symptoms, prioritising others) and health care provider (lack of accessible and trusted female GPs and poor experiences with GPs). Conclusions For 20 years women have consistently reported poor experiences in accessing care for AUB. The findings from our review indicate that drivers to impeding access are multiple; therefore any approaches to improve access will need to be multi-level – from comprising local sociocultural considerations to improved GP training.

Abstract
OBJECTIVES Bipolar Disorder (BD) is frequently comorbid with other psychiatric disorders. However, few studies systematically examine which disorders are more likely to occur pre- or post-BD onset. We examine the prevalence and Age At Onset (AAO) of psychiatric conditions in adults with BD. METHODS A structured clinical interview was used to assess lifetime history and AAO of alcohol and cannabis misuse, suicide attempts, anxiety and eating disorders in a French sample of euthymic patients with BD (n = 739). Regression analyses were used to test for statistically significant associations between rates and AAO of comorbidities in BD groups stratified by sex or subtype. RESULTS Prevalence of alcohol and cannabis misuse was associated with male sex and BD-I subtype; whilst most anxiety and eating disorders were associated with female sex. The AAO of most comorbid conditions preceded that of BD, except for panic disorder, agoraphobia and alcohol misuse. Few variations were observed in AAO of comorbidities according to groups. LIMITATIONS All assessments were retrospective, so estimates of prevalence rates and especially exact AAO of some comorbidities are at risk of recall bias. CONCLUSIONS Sex and BD subtype are associated with different rates of comorbid disorders. However, there were minimal between group differences in median AAO of comorbidities. By describing the chronological sequence of comorbidities in BD we were able to demonstrate that a minority of comorbidities typically occurred post-onset of BD. This is noteworthy as these disorders might be amenable to interventions aimed at early secondary prevention.

AbstractPurpose:Two common approaches to identify subgroups of patients with bipolar disorder are clustering methodology (mixture analysis) based on the age of onset, and a birth cohort analysis. This study investigates if a birth cohort effect will influence the results of clustering on the age of onset, using a large, international database.Methods:The database includes 4037 patients with a diagnosis of bipolar I disorder, previously collected at 36 collection sites in 23 countries. Generalized estimating equations (GEE) were used to adjust the data for country median age, and in some models, birth cohort. Model-based clustering (mixture analysis) was then performed on the age of onset data using the residuals. Clinical variables in subgroups were compared.Results:There was a strong birth cohort effect. Without adjusting for the birth cohort, three subgroups were found by clustering. After adjusting for the birth cohort or when considering only those born after 1959, two subgroups were found. With results of either two or three subgroups, the youngest subgroup was more likely to have a family history of mood disorders and a first episode with depressed polarity. However, without adjusting for birth cohort (three subgroups), family history and polarity of the first episode could not be distinguished between the middle and oldest subgroups.Conclusion:These results using international data confirm prior findings using single country data, that there are subgroups of bipolar I disorder based on the age of onset, and that there is a birth cohort effect. Including the birth cohort adjustment altered the number and characteristics of subgroups detected when clustering by age of onset. Further investigation is needed to determine if combining both approaches will identify subgroups that are more useful for research.

Abstract
AbstractObjective:Bipolar disorders (BD) are characterized by sleep disturbances and emotional dysregulation both during acute episodes and remission periods. We hypothesized that sleep quality (SQ) and emotional reactivity (ER) defined clusters of patients with no or abnormal SQ and ER and we studied the association with functioning.Method:We performed a bi-dimensional cluster analysis using SQ and ER measures in a sample of 533 outpatients patients with BD (in remission or with subsyndromal mood symptoms). Clusters were compared for mood symptoms, sleep profile and functioning.Results:We identified three clusters of patients: C1 (normal ER and SQ, 54%), C2 (hypo-ER and low SQ, 22%) and C3 (hyper-ER and low SQ, 24%). C1 was characterized by minimal mood symptoms, better sleep profile and higher functioning than other clusters. Although highly different for ER, C2 and C3 had similar levels of subsyndromal mood symptoms as assessed using classical mood scales. When exploring sleep domains, C2 showed poor sleep efficiency and a trend for longer sleep latency as compared to C3. Interestingly, alterations in functioning were similar in C2 and C3, with no difference in any of the sub-domains.Conclusion:Abnormalities in ER and SQ delineated three clusters of patients with BD and significantly impacted on functioning.

Abstract
Abstract
Thirteen laboratories analyzed samples of edible animal tissues for tetracycline residues. The method included extraction of analytes into buffer, elution from a C18 solid-phase extraction (SPE) cartridge, and reversed-phase liquid chromatographic (LC) analysis, including use of a confirmation column. An additional laboratory, using an alternative LC assay based on a different sample cleanup, also analyzed the samples. Results showed the 2 methods are comparable. The LC method for determination of cholortetracycline, oxytetracycline, and tetracycline in edible animal tissues has been adopted by AOAC INTERNATIONAL. Results from 13 laboratories indicate that the method under study provides generally better results at the higher concentrations tested than at concentrations near the detection limit and that there is less problem with interferences in muscle tissue than in kidney. The method can achieve reliable results for analytes and matrixes studied at concentrations from 0.1 to 0.6 ppm and above, depending on the analyte-matrix combination, with generally better performance to be expected with muscle than with kidney. The poorer performance for fortified samples, particularly kidney, was attributed to additional homogenization steps required to prepare these samples. Recovery of analytes from different

Abstract
Abstract
A collaborative study was conducted to evaluate the repeatability and reproducibility of an extension of AOAC Official Method 991.20, Nitrogen (Crude) in Milk, to animal feed, forage (plant tissue), grain, and oilseed materials. Test portions are digested in an aluminum block at 420°C in sulfuric acid with potassium sulfate and a copper catalyst. Digests are cooled and diluted, and concentrated sodium hydroxide is added to neutralize the acid and make the digest basic; the liberated ammonia is distilled by using steam distillation. The liberated ammonia is trapped in a weak boric acid solution and titrated with a stronger standardized acid, hydrochloric acid; colorimetric endpoint detection is used. Fourteen blind samples were sent to 13 collaborators in the United States, Denmark, Sweden, Germany, and the United Kingdom. Recoveries of nitrogen from lysine, tryptophan, and acetanilide were 86.8, 98.8, and 100.1%, respectively. The within-laboratory relative standard deviation (RSDr, repeatability) ranged from 0.40 to 2.38% for crude protein. The among-laboratories (including within-) relative standard deviation (RSDR, reproducibility) ranged from 0.44 to 2.38%. It is recommended that the method be adopted First Action by AOAC INTERNATIONAL. A lower concentration (1% H3BO3) of trapping solution was compared with the concentration specified in the original protocol (4% H3BO3) and was found comparable for use in an automatic titration system in which titration begins automatically as soon as distillation starts. The Study Directors recommend that 1% H3BO3 as an optional alternative to 4% boric acid trapping solution be allowed for automatic titrators that titrate throughout the distillation.

Abstract
BACKGROUND Methylation patterns in circulating cell-free DNA are potential biomarkers for cancer and other pathologies. Currently, bisulfite treatment underpins most DNA methylation analysis methods, however, it is known to fragment DNA. Circulating DNA is already short, and further fragmentation during bisulfite treatment is of concern, as it would potentially reduce the sensitivity of downstream assays. METHODS We used high molecular weight genomic DNA to compare fragmentation and recovery following bisulfite treatment with 2 commercially available kits (Qiagen). The bisulfite treated DNA was visualised on an agarose gel and quantified by qPCR. We also bisulfite treated, visualised and quantitated circulating DNA from plasma. RESULTS There was no difference in DNA fragmentation between the two kits tested, however, the Epitect Fast kit gave better recovery than the standard Epitect kit, with the same conversion efficiency. We also found that bisulfite treated circulating DNA migrates as distinct bands on agarose gels, suggesting that, in contrast to genomic DNA, it remains largely intact following treatment. Bisulfite treatment of 129 and 234 base PCR products confirmed that this was due to the short length of the circulating DNA fragments. Compared to double stranded DNA, bisulfite treated single stranded DNA gives a very weak signal on gel electrophoresis. CONCLUSIONS DNA fragmentation during bisulfite treatment does not contribute to loss of sensitivity in methylation analysis of circulating DNA. The absence of DNA fragments below approximately 170 bases from agarose gel images of purified circulating DNA raises the possibility that these fragments are single stranded following the DNA extraction step.

Abstract
Incidence of endometrial cancer is increasing rapidly in the developed world and is the most common gynaecological cancer in Australia and New Zealand. In line with obesity rates, the landscape and average age of women diagnosed with endometrial cancer are changing. There is still unmet need in early diagnosis, directed treatment, management of comorbidities and prevention strategies. This opinion piece aims to reflect on the current status of endometrial cancer in New Zealand in parallel to Australia, drawing out areas for future research and discussion.

Abstract
BACKGROUND Suicide attempts (SA) are more frequent in bipolar disorder (BD) than in most other mental disorders. Prevention strategies would benefit from identifying the risk factors of SA recurrence in BD. Substance use disorders (SUD) (including tobacco-related) are strongly associated with both BD and SA, however, their specific role for the recurrence of SA in BD remains inadequately investigated. Thus, we tested if tobacco smoking - with or without other SUDs - was independently associated with recurrent SA in BD. METHODS 916 patients from France and Norway with ascertained diagnoses of BD and reliable data about SA and SUD were classified as having no, single, or recurrent (≥2) SA. Five SUD groups were built according to the presence/absence/combination of tobacco, alcohol (AUD) and cannabis use disorders. Multinomial logistic regression was used to identify the correlates of SA recurrence. RESULTS 338 (37%) individuals reported at least one SA, half of whom (173, 51%) reported recurrence. SUD comorbidity was: tobacco smoking only, 397 (43%), tobacco smoking with at least another SUD, 179 (20%). Regression analysis showed that tobacco smoking, both alone and comorbid with AUD, depressive polarity of BD onset and female gender were independently associated with recurrent SA. LIMITATIONS Lack of data regarding the relative courses of SA and SUD and cross-national differences in main variables. CONCLUSION Tobacco smoking with- or without additional SUD can be important risk factors of SA recurrence in BD, which is likely to inform both research and prevention strategies.
