RESUMEN
OBJECTIVES: Deep margin elevation (DME) is a restorative approach offering the possibility of performing stepwise elevation of deep proximal cavities to create more favourable margins for direct or indirect restorations. The objectives of this scoping review were to explore what is known or unknown about DME by describing a wide ranging evidence base including peer reviewed literature and non-traditionally published information on the web. DATA: Data were extracted from the included evidence in order to describe the following: the extent and nature of the evidence base; the situations which are appropriate for DME; the materials and techniques which are used; the outcomes which have been measured in empirical studies; the risks which have been reported; and the findings which have been reported in studies which compared DME to surgical crown lengthening. SOURCES: This scoping review included a wide range of published evidence and extensive web searching for grey literature, including CPD, training and multimedia information. STUDY SELECTION: The findings revealed a range of published literature as well as freely available, online information advising practitioners about DME. Most empirical evidence was based on in vitro studies, and there were few clinical studies comparing DME to crown lengthening. Online information included recent, multimedia sources. CONCLUSIONS: DME is a technique that can be used with motivated patients with good oral hygiene if rubber dam isolation is achieved, if there is no invasion of the connective tissue space, and if a strict restorative protocol is adhered to. CLINICAL SIGNIFICANCE: With phasing out of amalgam and adhesive dentistry increasing in popularity, DME addresses multiple clinical problems associated with sub-gingival margins prior to restoration.

The anterior cingulate cortex (ACC) is critical for the perception and unpleasantness of pain.1,2,3,4,5,6 It receives nociceptive information from regions such as the thalamus and amygdala and projects to several cortical and subcortical regions of the pain neuromatrix.7,8 ACC hyperexcitability is one of many functional changes associated with chronic pain, and experimental activation of ACC pyramidal cells produces hypersensitivity to innocuous stimuli (i.e., allodynia).9,10,11,12,13,14 A less-well-studied projection to the ACC arises from a small forebrain region, the claustrum.15,16,17,18,19,20 Stimulation of excitatory claustrum projection neurons preferentially activates GABAergic interneurons, generating feed-forward inhibition onto excitatory cortical networks.21,22,23,24 Previous work has shown that claustrocingulate projections display altered activity in prolonged pain25,26,27; however, it remains unclear whether and how the claustrum participates in nociceptive processing and high-order pain behaviors. Inhibition of ACC activity reverses mechanical allodynia in animal models of persistent and neuropathic pain,1,9,28 suggesting claustrum inputs may function to attenuate pain processing. In this study, we sought to define claustrum function in acute and chronic pain. We found enhanced claustrum activity after a painful stimulus that was attenuated in chronic inflammatory pain. Selective inhibition of claustrocingulate projection neurons enhanced acute nociception but blocked pain learning. Inversely, chemogenetic activation of claustrocingulate neurons had no effect on basal nociception but rescued inflammation-induced mechanical allodynia. Together, these results suggest that claustrocingulate neurons are a critical component of the pain neuromatrix, and dysregulation of this connection may contribute to chronic pain.

Finasteride is commonly prescribed to treat benign prostate hyperplasia and male-pattern baldness in cis men and, more recently, trans individuals. However, the effect of finasteride on cardiovascular disease remains elusive. We evaluated the role of finasteride on atherosclerosis using low-density lipoprotein (LDL) receptor-deficient (Ldlr-/-) mice. Next, we examined the relevance to humans by analyzing the data deposited between 2009 and 2016 in the National Health and Nutrition Examination Survey. We show that finasteride reduces total plasma cholesterol and delays the development of atherosclerosis in Ldlr-/- mice. Finasteride reduced monocytosis, monocyte recruitment to the lesion, macrophage lesion content, and necrotic core area, the latter of which is an indicator of plaque vulnerability in humans. RNA sequencing analysis revealed a downregulation of inflammatory pathways and an upregulation of bile acid metabolism, oxidative phosphorylation, and cholesterol pathways in the liver of mice taking finasteride. Men reporting the use of finasteride showed lower plasma levels of cholesterol and LDL-cholesterol than those not taking the drug. Our data unveil finasteride as a potential treatment to delay cardiovascular disease in people by improving the plasma lipid profile.

Loss-of-function of DDX3X is a leading cause of neurodevelopmental disorders (NDD) in females. DDX3X is also a somatically mutated cancer driver gene proposed to have tumour promoting and suppressing effects. We perform saturation genome editing of DDX3X, testing in vitro the functional impact of 12,776 nucleotide variants. We identify 3432 functionally abnormal variants, in three distinct classes. We train a machine learning classifier to identify functionally abnormal variants of NDD-relevance. This classifier has at least 97% sensitivity and 99% specificity to detect variants pathogenic for NDD, substantially out-performing in silico predictors, and resolving up to 93% of variants of uncertain significance. Moreover, functionally-abnormal variants can account for almost all of the excess nonsynonymous DDX3X somatic mutations seen in DDX3X-driven cancers. Systematic maps of variant effects generated in experimentally tractable cell types have the potential to transform clinical interpretation of both germline and somatic disease-associated variation.

BACKGROUND: Evidence attests a link between junior doctors' working conditions and psychological distress. Despite increasing concerns around suicidality among junior doctors, little is known about its relationship to their working conditions. AIMS: To (a) establish the prevalence of suicidal ideation among junior doctors in the National Health Service; (b) examine the relationships between perceived working conditions and suicidal ideation; and (c) explore whether psychological distress (e.g. symptoms of depression and anxiety) mediates these relationships. METHOD: Junior doctors were recruited between March 2020 and January 2021, for a cross-sectional online survey. We used the Health and Safety Executive's Management Standards Tool; Depression, Anxiety and Stress Scale 21; and Paykel Suicidality Scale to assess working conditions, psychological distress and suicidality, respectively. RESULTS: Of the 424 participants, 50.2% reported suicidal ideation, including 6.1% who had made an attempt on their own life. Participants who identified as LGBTQ+ (odds ratio 2.18, 95% CI 1.15-4.12) or reported depression symptoms (odds ratio 1.10, 95% CI 1.07-1.14) were more likely to report suicidal ideation. No direct relationships were reported between working conditions (i.e. control, support, role clarity, strained relationships, demand and change) and suicidal ideation. However, depression symptoms mediated all six relationships. CONCLUSIONS: This sample of junior doctors reported alarming levels of suicidal ideation. There may be an indirect relationship between working conditions and suicidal ideation via depressive symptoms. Clearer research exploring the experience of suicidality in junior doctors is needed, including those who identify as LGBTQ+. Systematic interventions addressing working environment are needed to support junior doctors' mental health.
RESUMEN
The classification of non-specific chronic low back pain (CLBP) according to multidimensional data could guide clinical management; yet recent systematic reviews show this has not been attempted. This was a prospective cross-sectional study of participants with CLBP (n = 21) and age-, sex- and height-matched pain-free controls (n = 21). Nervous system, lumbar spinal tissue and psychosocial factors were collected. Dimensionality reduction was followed by fuzzy c-means clustering to determine sub-groups. Machine learning models (Support Vector Machine, k-Nearest Neighbour, Naïve Bayes and Random Forest) were used to determine the accuracy of classification to sub-groups. The primary analysis showed that four factors (cognitive function, depressive symptoms, general self-efficacy and anxiety symptoms) and two clusters (normal versus impaired psychosocial profiles) optimally classified participants. The error rates in classification models ranged from 4.2 to 14.2% when only CLBP patients were considered and increased to 24.2 to 37.5% when pain-free controls were added. This data-driven pilot study classified participants with CLBP into sub-groups, primarily based on psychosocial factors. This contributes to the literature as it was the first study to evaluate data-driven machine learning CLBP classification based on nervous system, lumbar spinal tissue and psychosocial factors. Future studies with larger sample sizes should validate these findings.

Decades of research into chronic pain has deepened our understanding of the cellular mechanisms behind this process. However, a failure to consider the biological variable of sex has limited the application of these breakthroughs into clinical application. In the present study, we investigate fundamental differences in chronic pain between male and female mice resulting from inflammatory activation of the innate immune system. We provide evidence that female mice are more sensitive to the effects of macrophages. Injecting small volumes of media conditioned by either unstimulated macrophages or macrophages stimulated by the inflammatory molecule TNFα lead to increased pain sensitivity only in females. Interestingly, we find that TNFα conditioned media leads to a more rapid resolution of mechanical hypersensitivity and altered immune cell recruitment to sites of injury. Furthermore, male and female macrophages exhibit differential polarization characteristics and motility after TNFα stimulation, as well as a different profile of cytokine secretions. Finally, we find that the X-linked gene Tlr7 is critical in the facilitating the adaptive resolution of pain in models of acute and chronic inflammation in both sexes. Altogether, these findings suggest that although the cellular mechanisms of pain resolution may differ between the sexes, the study of these differences may yield more targeted approaches with clinical applications.
RESUMEN
Purpose: Intimate Partner Violence and Abuse (IPVA) is as a major health concern globally. The prevalence of IPVA perpetration and victimisation has been found to be higher in military compared to civilian populations. Of concern, help-seeking for other psychosocial difficulties among military communities has been shown to be both limited and challenging, and military personnel could face additional or amplified barriers to help-seeking for IPVA than their civilian counterparts. This study aimed to use qualitative methods to explore the experiences of, and barriers to, help-seeking for IPVA victimisation and perpetration among UK military personnel. Methods: Thematic analysis was conducted on 40 one-to-one semi-structured interviews with military personnel (29 male, 11 female). Results: Four superordinate themes were derived, thematically organised according to different levels of the social ecological model: Military cultural factors; Support service factors; Interpersonal factors; and Individual factors. At a military cultural level, participants described difficulties in help-seeking for IPVA resulting from widespread stigma and hypermasculine attitudes in military communities, minimisation of violence, perceived pressure from chain of command, and fear of consequences of reporting. At a support-service level, participants' negative views or experiences and lack of awareness of services were also significant in deterring help-seeking. At an interpersonal level, participants recounted how relationships with military colleagues, their partner and their family could be both instrumental or a hindrance to help-seeking for IPVA. At an individual level, lack of insight into IPVA and different forms of abuse were suggested through minimisation of violence and described to contribute to delay in help-seeking. Shame, compounded by multi-layered stigma present at each social ecological model level, was a key reason for delaying or avoiding help-seeking. Conclusions: The findings indicate the added challenges in help-seeking for IPVA experienced by military personnel and highlight a need for a whole systems approach to improve the provision of support for IPVA in the military serving and ex-serving community to instil meaningful change.
RESUMEN
Purpose: Digital tools may improve chronic obstructive pulmonary disease (COPD) management, but further evidence of significant, persisting benefits are required. The RECEIVER trial was devised to evaluate the Lenus COPD support service by determining if people with severe COPD would continue to utilize the co-designed patient web application throughout study follow-up and to explore the impact of this digital service on clinical outcomes with its adoption alongside routine care. Patients and Methods: The prospective observational cohort hybrid implementation-effectiveness study began in September 2019 and included 83 participants. Recruitment stopped in March 2020 due to COVID-19, but follow-up continued as planned. A contemporary matched control cohort was identified to compare participant clinical outcomes with and minimize biases associated with wider COVID-19 impacts. Utilization was determined by daily COPD assessment test (CAT) completion through the application. Survival metrics and post-index date changes in annual hospitalizations were compared between the RECEIVER and control cohorts. Longitudinal quality of life and symptom burden data and community-managed exacerbation events were also captured through the application. Results: High and sustained application utilization was noted across the RECEIVER cohort with a mean follow-up of 78 weeks (64/83 participants completed at least one CAT entry on ≥50% of possible follow-up weeks). Subgroup analysis of participants resident in more socioeconomically deprived postcode areas revealed equivalent utilization. Median time to death or a COPD or respiratory-related admission was higher in the RECEIVER cohort compared to control (335 days vs 155 days). Mean reduction in annual occupied bed days was 8.12 days vs 3.38 days in the control cohort. Quality of life and symptom burden remained stable despite the progressive nature of COPD. Conclusion: The sustained utilization of the co-designed patient application and improvements in participant outcomes observed in the RECEIVER trial support scale-up implementation with continued evaluation of this digital service.

Opioid addiction is characterized by adaptations in the mesolimbic dopamine system that occur during chronic opioid use. Alterations in dopaminergic transmission contribute to pathological drug-seeking behavior and other symptoms associated with opioid withdrawal following drug discontinuation, making drug abstinence challenging and contributing to high rates of relapse among those suffering from substance use disorder. Recently, the use of dopamine partial agonists has been proposed as a potential strategy to restore dopaminergic signalling during drug withdrawal, while avoiding the adverse side effects associated with stronger modulators of dopaminergic transmission. We investigated the effects of the atypical antipsychotic brexpiprazole, which is a partial agonist at dopamine D2 and D3 receptors, in a mouse model of opioid dependence. The development of opioid dependence in mice is characterized by locomotor sensitization, analgesic tolerance, opioid-induced hyperalgesia, and drug-seeking behavior. We set up four paradigms to model the effects of brexpiprazole on each of these adaptations that occur during chronic opioid use in male and female C57BL/6J mice. Concomitant treatment of brexpiprazole during chronic morphine administration attenuated the development of locomotor sensitization. Brexpiprazole treatment abolished morphine place preference and blocked reinstatement of this behavior following extinction. Brexpiprazole treatment did not alter morphine analgesia, nor did it impact the development of morphine tolerance. However, brexpiprazole treatment did prevent the expression of opioid-induced hyperalgesia in a tail-withdrawal assay, while failing to improve somatic withdrawal symptoms. Altogether, these results provide preclinical evidence for the efficacy of brexpiprazole as a modulator of dopamine-dependent behaviors during opioid use and withdrawal.

OBJECTIVE: Recovery Colleges support recovery for adults with mental health problems, through coproduction and education principles. This study aimed to determine whether students at three Recovery Colleges in England were representative of mental health service users. METHODS: Gender, age, ethnicity, diagnosis, involuntary detention, and inpatient admission were extracted from clinical records. Data for all service user students enrolled, and those who had attended 70% of a Recovery College course were compared to mental health services caseloads, using chi-square goodness-of-fit tests. RESULTS: Clinical records were identified for 1,788 students. Significant differences were identified for gender, age, and diagnosis (p < .001). In some Colleges, more students had recent inpatient admissions or involuntary detentions. CONCLUSIONS AND IMPLICATIONS FOR PRACTICE: Service user students were largely representative of mental health service users, although some groups were underrepresented. Further research is needed to understand why, so that Recovery Colleges can continue to address inequalities. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

BACKGROUNDS: Magnetic resonance imaging is the primary method for local staging in rectal cancer patients. Administration of intravenous (IV) hyoscine butylbromide is thought to improve accuracy, but there are contraindications and potential adverse effects. The aim was to assess the efficacy of IV hyoscine butylbromide on the accuracy of MRI rectal cancer staging of T2 and T3 rectal cancers. METHODS: A retrospective cohort study was carried out on patients prospectively recorded on the Cabrini Monash colorectal neoplasia database. A total of 74 patients (53 males, 21 females) MRI pelvis and rectums with antispasmodics were performed at multiple centres in the pre-operative setting between 2010 and 2016. Each patient underwent total mesorectal excision of rectal cancer. The excision specimens were assessed and given a pathological TNM stage, which was considered the reference standard. RESULTS: There was no statistically significant impact on the overall accuracy of MRI rectal cancer staging between patient groups who received IV hyoscine butylbromide and groups who did not receive IV hyoscine butylbromide. The accuracy of T2 and T3 staged rectal cancers was more likely to be correct (compared with T1 cancers) with the administration of IV hyoscine butylbromide. Still, there was no improvement in the accuracy of N-staging. CONCLUSION: Given the potential side effects and adverse outcomes of IV anti-spasmodic agents, department protocols may need to be re-assessed regarding the prescription of these medications for MRI rectal cancer staging.

Severe antisocial behavior in girls, best exemplified by conduct disorder (CD), is a serious clinical and public health problem. Treatment is difficult, particularly in girls with comorbid internalizing disorders. Identifying biological correlates may help to develop new treatments or diagnostic, prognostic, or treatment response biomarkers. Based on our earlier work and research from others occurring primarily in boys with severe antisocial behavior, it is possible that abnormalities in the hypothalamic pituitary adrenal (HPA) axis circadian cortisol cycle may be associated with female CD. Additionally, research suggests that the presence of comorbid internalizing disorders may be related to differences in cortisol secretion, compared to subjects who only have CD. Our study aimed: 1) to compare the circadian cortisol cycle in 98 girls with CD, 15-16 years of age to 47 girls without any psychiatric disorder (ND) and 2) to compare the cycle in girls with CD and comorbid internalizing disorders (CD + INT) to those without such comorbidity (CD Only). Salivary cortisol was collected over 24 h during weekdays at scheduled times, with protocol adherence measures in place. Unstructured covariance pattern modeling, controlling for effects of age, social class, IQ, and awakening time was used to analyze cortisol data. CD was associated with overall lower cortisol secretion (p = 0.03), but this difference was due to a lower volume of cortisol secreted 30 min after awakening (area under the curve with respect to ground, p = 0.01). Circadian cortisol secretion was no different in the CD+INT group compared to the CD Only group (p = 0.52). Our findings need to be replicated using current consensus guidelines for the assessment of the CAR. We also suggest two new avenues of research in this field.

There is evidence that Intimate Partner Violence and Abuse (IPVA) is more prevalent among military populations compared with civilian populations. However, there has been limited research into the help-seeking experiences of civilian victim-survivors who have experienced IPVA within relationships with military personnel. This qualitative study aimed to explore the experiences of, and barriers to, help-seeking for IPVA victimisation among civilian partners of military personnel in order to identify strategies to improve the management of IPVA both within the military and civilian sectors. The study adopted a descriptive cross-sectional study design and used qualitative research methods. One-to-one telephone interviews were conducted with civilian victim-survivors (n = 25) between January and August 2018. Interview transcripts were analysed using thematic analysis. Three superordinate themes were derived: (1) Drivers to help-seeking; (2) Barriers to help-seeking; and (3) Experiences of services. The findings indicate difficulties in help-seeking for IPVA among civilian partners of military personnel due to stigma, fear, dependency, poor understanding of IPVA, lack of appropriate and timely support, and a perceived lack of victim support. Difficulties in help-seeking were perceived by participants to be amplified by military culture, public perceptions of the military, military protection of personnel and the lack of coordination between civilian and military judicial services. This study reinforces the need for a military specific Domestic Abuse strategy, identifies vulnerable groups and highlights a need for both increased awareness and understanding of IPVA within civilian and military services in order to provide adequate victim protection.
RESUMEN
DDX3X variants are a common cause of intellectual disability (ID) in females, and have been associated with autism spectrum disorder and emotional-behavioural difficulties. In this study, we compared phenotypic data for 23 females with DDX3X variants, to 23 females with ID and other genetic diagnoses. We found a wide range of adaptive, social and emotional function within the DDX3X group. Autism characteristics did not differ between DDX3X and comparison groups, while levels of anxiety and self-injurious behaviour (SIB) were significantly higher in the DDX3X group. Within the DDX3X group, adaptive function, autism characteristics, anxiety and SIB scores were positively correlated, with evidence for group-specific associations with SIB. Future work is warranted to explore the multilevel mechanisms contributing to social and emotional development in individuals with DDX3X variants.

BACKGROUND: Doctors, including junior doctors, are vulnerable to greater levels of distress and mental health difficulties than the public. This is exacerbated by their working conditions and cultures. While this vulnerability has been known for many years, little action has been taken to protect and support junior doctors working in the NHS. As such, we present a series of recommendations from the perspective of junior doctors and other relevant stakeholders, designed to improve junior doctors' working conditions and, thus, their mental health. METHODS: We interviewed 36 junior doctors, asking them for recommendations for improving their working conditions and culture. Additionally, we held an online stakeholder meeting with a variety of healthcare professionals (including junior doctors), undergraduate medical school leads, postgraduate speciality school leads and NHS policymakers where we asked what could be done to improve junior doctors' working conditions. We combined interview data with notes from the stakeholder discussions to produce this set of recommendations. RESULTS: Junior doctor participants and stakeholders made organisational and interpersonal recommendations. Organisational recommendations include the need for more environmental, staff and educational resources as well as changes to rotas. Interpersonal recommendations include changes to communication and recommendations for better support and teamwork. CONCLUSION: We suggest that NHS policymakers, employers and managers consider and hopefully implement the recommendations set out by the study participants and stakeholders as reported in this paper and that the gold standards of practice which are reported here (such as examples of positive learning environments and supportive supervision) are showcased so that others can learn from them.

Purpose: The prevalence of Intimate Partner Violence and Abuse (IPVA) perpetration and victimisation has been found to be higher in serving and ex-serving military samples compared to civilians. Despite this, there is a lack of qualitative research exploring the IPVA experiences of couples in which one or both partners are serving or have served in the military. This qualitative study aimed to explore IPVA experiences within the UK military community from the perspective of serving and ex-serving military personnel and civilian partners of UK military personnel. Method: One-to-one telephone interviews were conducted with 40 serving and ex-serving military personnel (29 male, 11 female) and 25 female civilian partners. Data was analysed using thematic analysis. Results: Four superordinate themes were derived: (1) patterns and directions of IPVA, (2) types of IPVA, (3) perceived drivers of IPVA and (4) perceived impact of IPVA. The findings point to frequent bidirectional abuse in part driven by poor communication and emotion regulation, whilst also highlighting the experiences of severe IPVA victimisation of civilian partners by military personnel motivated by power and control. Perceived drivers of both IPVA perpetration and victimisation include military factors borne of military culture or training, alcohol and mental health difficulties. Conclusion: These results highlight the role of cultural norms, as well as the role of emotion dysregulation, poor communication skills and mental health difficulties in explaining and perpetuating abuse within ecological theoretical frameworks of violence among couples within which one or both partners are serving or ex-serving military personnel.
RESUMEN
Objective: To examine the trajectories of cognitive, motor and behavioural development in infants with NF1 compared to infants without a family history of neurodevelopmental difficulties. Study design: Infants with NF1 and low-risk controls were recruited from 5 months of age and followed longitudinally. Data from standardised tests was gathered at 5, 10 and 14 months and developmental trajectories of motor, language, behaviour, sleep, social development and parent-infant interaction were examined. Linear mixed modelling was used to estimate group differences in cognitive and behavioural measures over time. Results: No group differences were observed on Mullen Scale of Early Learning, overall adaptive functioning, temperament or behavioural measures. There were no group differences observed on measures of social communication or parent-infant interaction. Over the course of development, the NF1 group slept less and took more time to settle to sleep as compared to the control group. Maternal education was significantly associated with cognitive and behavioural developmental outcomes in both groups. Conclusion: Cognitive, social and behavioural impairments are a cause of significant functional morbidity in children with NF1. This report is the first study to investigate the trajectories of cognitive, motor and behavioural development in infancy in NF1. Our results demonstrate that overall cognitive and behavioural developmental trajectories of the NF1 group in the infancy period are similar to controls. Given previous reports of delayed development in the NF1 cohort by 40 months, early clinical interventions strategies to promote sleep hygiene may be beneficial to optimise developmental outcomes.
RESUMEN
OBJECTIVES: This paper explored the self-reported prevalence of depression, anxiety and stress among junior doctors during the COVID-19 pandemic. It also reports the association between working conditions and psychological distress experienced by junior doctors. DESIGN: A cross-sectional online survey study was conducted, using the 21-item Depression, Anxiety and Stress Scale and Health and Safety Executive scale to measure psychological well-being and working cultures of junior doctors. SETTING: The National Health Service in the UK. PARTICIPANTS: A sample of 456 UK junior doctors was recruited online during the COVID-19 pandemic from March 2020 to January 2021. RESULTS: Junior doctors reported poor mental health, with over 40% scoring extremely severely depressed (45.2%), anxious (63.2%) and stressed (40.2%). Both gender and ethnicity were found to have a significant influence on levels of anxiety. Hierarchical multiple linear regression analysis outlined the specific working conditions which significantly predicted depression (increased demands (ß=0.101), relationships (ß=0.27), unsupportive manager (ß=-0.111)), anxiety (relationships (ß=0.31), change (ß=0.18), demands (ß=0.179)) and stress (relationships (ß=0.18), demands (ß=0.28), role (ß=0.11)). CONCLUSIONS: The findings illustrate the importance of working conditions for junior doctors' mental health, as they were significant predictors for depression, anxiety and stress. Therefore, if the mental health of junior doctors is to be improved, it is important that changes or interventions specifically target the working environment rather than factors within the individual clinician.
