Family and occupational functioning following military trauma exposure and moral injury

INTRODUCTION

Evidence is growing regarding the impact of potentially morally injurious events (PMIEs) on mental health; yet how moral injury may affect an individual's occupational and familial functioning remains poorly understood.

METHOD

Thirty male veterans who reported exposure to either traumatic or morally injurious events and 15 clinicians were recruited for semi-structured qualitative interviews.

RESULTS

While many veterans experienced psychological distress postevent, those who experienced PMIEs especially reported social withdrawal and engagement in aggressive, risk-taking behaviours. This was highly distressing for family members and created a tense, volatile home and workplace environment that was difficult for others to navigate. Following PMIEs, employment could be used as a cognitive avoidance strategy or as a means to atone for transgressive acts. In cases of moral injury, clinicians considered that targeted support for spouses and accessible guidance to help children to better understand how their military parent may be feeling would be beneficial.

CONCLUSIONS

This study provides some of the first evidence of the pervasive negative impact of PMIEs on veterans' familial and occupational functioning. These findings highlight the need to comprehensively screen for the impact of moral injury on daily functioning in future studies that goes beyond just an assessment of psychological symptoms.

Mental health treatment experiences of commonwealth veterans from diverse ethnic backgrounds who have served in the UK military

INTRODUCTION

Research has shown that the likelihood of ex-military personnel developing mental health problems following service is around one in five. Little is known about the barriers to accessing mental health in veterans from diverse ethnic backgrounds. This study aims to explore mental health treatment experiences of veterans from commonwealth countries and therefore diverse ethnic backgrounds.

METHODS

Semi-structured interviews were conducted over the telephone with veterans from commonwealth countries. Veterans were recruited from a mental health charity and were at various stages of treatment.

RESULTS

We interviewed six veterans who were from a diverse range of commonwealth countries including St Lucia, Gambia, Ghana, Fiji and South Africa. All had served in the UK army in combat roles. Our findings consisted of key themes: (1) feeling that they are treated differently, (2) they felt as though they were unheard when reaching out for help, (3) systemic pressures such as financial difficulties, missed opportunities and lack of insight about mental health and (4) the importance of involving the wider community in care.

CONCLUSION

Our findings highlight some distinct barriers to mental health treatment that commonwealth veterans experience. The themes reported by the participants appear to suggest they had experience signs of institutional racism. Suggesting the importance of highlighting these issues, and to help overcome these potential barriers to accessing services. Given that commonwealth veterans involvement in the UK military is significant and increasing, the findings in this study should be used to support this population by implementing service provision and policy.

A Big HIIT: A Fracture Dislocation of the Hip in a Young Man Participating in Extreme Conditioning Exercise: A Case Report

CASE

Hip dislocations with associated acetabular fracture are rare events usually associated with high-energy trauma. We describe an unusual case of low-energy acetabular fracture dislocation sustained by a 30-year-old athletic male athlete during a high-intensity training program.

CONCLUSION

Correct execution of training programs is important. Healthcare professionals as well as participants and instructors of extreme conditioning programs should be aware of this serious complication. Avoidance of this injury may be possible with increased interval recovery and improved technique.

Dissecting the phenotypic heterogeneity in sensory features in autism spectrum disorder: a factor mixture modelling approach

BACKGROUND

Heterogeneity in the phenotypic presentation of autism spectrum disorder (ASD) is apparent in the profile and the severity of sensory features. Here, we applied factor mixture modelling (FMM) to test a multidimensional factor model of sensory processing in ASD. We aimed to identify homogeneous sensory subgroups in ASD that differ intrinsically in their severity along continuous factor scores. We also investigated sensory subgroups in relation to clinical variables: sex, age, IQ, social-communication symptoms, restricted and repetitive behaviours, adaptive functioning and symptoms of anxiety and attention-deficit/hyperactivity disorder.

METHODS

Three hundred thirty-two children and adults with ASD between the ages of 6 and 30 years with IQs varying between 40 and 148 were included. First, three different confirmatory factor models were fit to the 38 items of the Short Sensory Profile (SSP). Then, latent class models (with two-to-six subgroups) were evaluated. The best performing factor model, the 7-factor structure, was subsequently used in two FMMs that varied in the number of subgroups: a two-subgroup, seven-factor model and a three-subgroup and seven-factor model.

RESULTS

The 'three-subgroup/seven-factor' FMM was superior to all other models based on different fit criteria. Identified subgroups differed in sensory severity from severe, moderate to low. Accounting for the potential confounding effects of age and IQ, participants in these sensory subgroups had different levels of social-communicative symptoms, restricted and repetitive behaviours, adaptive functioning skills and symptoms of inattention and anxiety.

LIMITATIONS

Results were derived using a single parent-report measure of sensory features, the SSP, which limits the generalisability of findings.

CONCLUSION

Sensory features can be best described by three homogeneous sensory subgroups that differ in sensory severity gradients along seven continuous factor scores. Identified sensory subgroups were further differentiated by the severity of core and co-occurring symptoms, and level of adaptive functioning, providing novel evidence on the associated clinical correlates of sensory subgroups. These sensory subgroups provide a platform to further interrogate the neurobiological and genetic correlates of altered sensory processing in ASD.

Confidentiality and psychological treatment of moral injury: the elephant in the room

Morally injurious incidents may present ethical or legal quandaries, yet how military or civilian clinicians should manage such disclosures is poorly understood. Individuals who experience moral injury may be reluctant to seek help due to concerns about the legal ramifications of disclosure. Guidance on breaching patient confidentiality differs by regulatory body but also by profession, geography and context. As moral injury continues to become recognised in clinical practice, in the military and elsewhere, clarity is needed regarding best practice in managing moral injury cases and the dilemmas they present.

Control of three gastrointestinal illness outbreaks in a British Role 1 facility in Afghanistan: a primary care perspective

INTRODUCTION

In 2019, Camp Qargha (QAA), a British-led multinational military camp in Kabul, had three of the largest outbreaks of gastrointestinal illness (GI) experienced by the British Military since 2003. This paper discusses the incidence, the response of the British-led Role 1 (R1) medical treatment facility, identifies potential causative and exacerbating factors, and explains the control measures initiated.

METHOD

GI in QAA results in local and UK military-wide data collection including in the form of local GI questionnaires, FMed85 forms and EpiNATO returns. The data from these was used to identify trends during and after outbreaks and produce environmental health (EH) and local outbreak reports.

RESULTS

Overall, among the outbreaks 56% of stool samples tested positive for norovirus. In each outbreak incidence peaked within the first 3 days, and hardened multiperson rooms were worst affected. 206 patient presentations occurred during the three outbreaks, 706 working days were lost in isolation, with QAA shut down while in quarantine for 27 days.

DISCUSSION

Significant strain was placed on QAA and the R1. Causative factors may include close interaction with the local national (LN) population, a high population density and accommodation being limited by specific national infrastructure protocols in an operational environment.

CONCLUSION

Early recognition of GI, positive standard operating procedures and good hygiene habits are essential to prevent the spread of GI such as norovirus. An early awareness of LN population illness patterns will allow the R1 and command to be better prepared for outbreaks in the future.

Predictors of not working among treatment-seeking UK veterans: a cross-sectional study

INTRODUCTION

Many veterans do well reintegrating to civilian life following military service. Yet, many face difficulties in finding and securing work. Veterans are more likely than civilians to experience work difficulties, but there remains little research investigating contributing factors, particularly among samples of treatment-seeking veterans. As such, the study examines predictors of not working among UK treatment-seeking veterans.

DESIGN

The study employed a cross-sectional design.

METHODS

Of 667 treatment-seeking UK veterans, 403 (M_age =50.94) provided information on a range of demographic variables, military-related experiences, the total number of physical health conditions and mental health outcomes. Work status was categorised as not working due to illness (M_age =48.15), not working due to other reasons (M_age =61.92) and currently working (M_age = 46.13).

RESULTS

Prevalence rates of not working was 69%. Not working was predicted by a greater number of physical health problems as well as more years since leaving the military. Not working due to poor health was independently predicted by symptoms of post-traumatic stress disorder (PTSD) and younger age, while not working due to other reasons was predicted by older age.

CONCLUSIONS

The study revealed that treatment-seeking veterans of younger age with a high number of physical health difficulties, symptoms of PTSD and more years since leaving the military are most at risk of not working due to ill health. The findings have important implications for identifying veterans most at risk of not working and offer the opportunity to tailor rehabilitation programmes to promote successful veteran reintegration into civilian life.

Comparison of Brain Morphology in Alzheimer’s Dementia in the General Population and Demented Subjects with Down’s Syndrome

Aim:

To compare Magnetic Resonance Imaging (MRI) findings in Alzheimer's dementia (AD) in the general population with Down's syndrome dementia.

Background review: AD is characterised by cognitive dysfunction interfering with activities of daily living. Mild cognitive impairment (MCI) is an intermediate state between normal aging and dementia. People with Down's syndrome have an increased risk of developing AD. AD pathology initially appears in the entorhinal cortex, followed by the hippocampus and later in the temporal lobes. These areas are critical for memory functioning.

Method:

Volumetric analysis was performed on MRI brain scans using Measure software. Manual tracing was undertaken for the hippocampus, temporal lobes and lateral ventricles as well as the total brain volume of the cerebral hemispheres and cerebellum. Brain volumes were normalised as a percentage of traced intracranial volumes. Freesurfer software was used to obtain entorhinal cortical thickness measures. Statistical analysis was undertaken using SPSS15.

Results:

Subjects with AD (n=46), MCI (n=28) and controls (n=39) were compared with Down's syndrome demented subjects (DS+, n=20), non-demented subjects with Down's syndrome (DS-, n=45) and age-matched controls (n=43). Hippocampi, entorhinal cortex and temporal lobes were significantly reduced in AD and DS+ compared to controls. Lateral ventricles were significantly increased in AD and DS+ compared to controls. MCI and DS- produced findings between those of dementia and controls.

Conclusions:

Critical memory regions atrophy in dementia corresponding to decreased cognitive functioning. DS+ morphology is comparable to AD in the general population but the atrophy is less pronounced.

Effects of route of administration on oxytocin-induced changes in regional cerebral blood flow in humans

Could nose-to-brain pathways mediate the effects of peptides such as oxytocin (OT) on brain physiology when delivered intranasally? We address this question by contrasting two methods of intranasal administration (a standard nasal spray, and a nebulizer expected to improve OT deposition in nasal areas putatively involved in direct nose-to-brain transport) to intravenous administration in terms of effects on regional cerebral blood flow during two hours post-dosing. We demonstrate that OT-induced decreases in amygdala perfusion, a key hub of the OT central circuitry, are explained entirely by OT increases in systemic circulation following both intranasal and intravenous OT administration. Yet we also provide robust evidence confirming the validity of the intranasal route to target specific brain regions. Our work has important translational implications and demonstrates the need to carefully consider the method of administration in our efforts to engage specific central oxytocinergic targets for the treatment of neuropsychiatric disorders.

Childhood adversities in UK treatment-seeking military veterans

Introduction

The long-term consequences of adverse childhood experiences (ACEs) on adult physical and mental health are well documented in the literature. The current study sought to examine this relationship in a sample of UK treatment-seeking military veterans.

Methods

The data were collected through a cross-sectional self-report survey from military veterans who have sought help for mental health difficulties from a veteran-specific UK-based charity. The response rate was 67.2% (n=403) and the effective sample for this study consisted of 386 male veterans. Participants’ history of ACEs and current mental/physical health difficulties were assessed. A latent class analysis was conducted to categorise participants into subgroups based on their ACEs and the relationship of these to the mental and physical health outcomes was examined.

Results

Five classes of veterans with different combinations of ACEs were identified. A total of 97% reported at least one ACE. There were minimal differences between the classes on mental and physical health outcomes, but the total number of ACEs was related to aggression, common mental health problems and post-traumatic stress disorder (PTSD).

Conclusions

No combination of ACEs was specifically predictive of adverse mental/physical health difficulties in our sample. Instead, those with a higher number of ACEs may be more prone to developing problems with aggression, common mental health problems and PTSD. Assessing the history of childhood adversities in military veterans is therefore important when veterans are seeking help for mental health difficulties, as some of these may be related to childhood adversities and may need to be addressed in treatment.

Week 48 Resistance Analyses of the Once-Daily, Single-Tablet Regimen Darunavir/Cobicistat/Emtricitabine/Tenofovir Alafenamide (D/C/F/TAF) in Adults Living with HIV-1 from the Phase III Randomized AMBER and EMERALD Trials

Darunavir/cobicistat/emtricitabine/tenofovir alafenamide (D/C/F/TAF) 800/150/200/10 mg is being investigated in two Phase III trials, AMBER (NCT02431247; treatment-naive adults) and EMERALD (NCT02269917; treatment-experienced, virologically suppressed adults). Week 48 AMBER and EMERALD resistance analyses are presented. Postbaseline samples for genotyping/phenotyping were analyzed from protocol-defined virologic failures (PDVFs) with viral load (VL) ≥400 copies/mL at failure/later time points. Post hoc analyses were deep sequencing in AMBER, and HIV-1 proviral DNA from baseline samples (VL <50 copies/mL) in EMERALD. Through week 48 across both studies, no darunavir, primary PI, or tenofovir resistance-associated mutations (RAMs) were observed in HIV-1 viruses of 1,125 participants receiving D/C/F/TAF or 629 receiving boosted darunavir plus emtricitabine/tenofovir-disoproxil-fumarate. In AMBER, the nucleos(t)ide analog reverse transcriptase inhibitor (N(t)RTI) RAM M184I/V was identified in HIV-1 of one participant during D/C/F/TAF treatment. M184V was detected pretreatment as a minority variant (9%). In EMERALD, in participants with prior VF and genoarchive data (N = 140; 98 D/C/F/TAF and 42 control), 4% had viruses with darunavir RAMs, 38% with emtricitabine RAMs, mainly at position 184 (41% not fully susceptible to emtricitabine), 4% with tenofovir RAMs, and 21% ≥ 3 thymidine analog-associated mutations (24% not fully susceptible to tenofovir) detected at screening. All achieved VL <50 copies/mL at week 48 or prior discontinuation. D/C/F/TAF has a high genetic barrier to resistance; no darunavir, primary PI, or tenofovir RAMs were observed through 48 weeks in AMBER and EMERALD. Only one postbaseline M184I/V RAM was observed in HIV-1 of an AMBER participant. In EMERALD, baseline archived RAMs to darunavir, emtricitabine, and tenofovir in participants with prior VF did not preclude virologic response.

Serum Iron Analytes in Healthy and Diseased Florida Manatees (Trichechus manatus latirostris)

Serum iron concentration is usually decreased in true iron deficiency and with inflammatory disease in man and domestic animals. Serum total iron binding capacity (TIBC) may be increased in true iron deficiency and decreased with inflammatory disease. This prospective study was designed to measure serum iron analytes in healthy free-ranging and housed Florida manatees (Trichechus manatus latirostris) of both sexes and various ages and to evaluate the effects of diseases common to manatees on these analytes. Blood samples were collected without anticoagulant from 137 healthy free-ranging manatees, 90 healthy housed manatees and 74 free-ranging diseased manatees, and serum was prepared by centrifugation. Serum iron concentration and unsaturated iron binding capacity were measured colourimetrically, and TIBC and percent transferrin saturation with iron were calculated. Serum amyloid A (SAA) was measured to assist in the health assessment of manatees and provide evidence of inflammation in diseased manatees. Based on the serum iron analytes, iron availability was lower in immature manatees compared with adults, and it was lower in housed manatees compared with free-ranging manatees. In contrast to other mammals studied, serum iron concentration was elevated rather than depressed in late pregnancy. Serum iron concentrations and transferrin saturation with iron percentages were significantly lower, and SAA concentrations were significantly higher, in diseased (ill and injured) manatees compared with healthy manatees. Serum iron concentration and transferrin saturation with iron values were negatively correlated with SAA concentrations, and manatees with the highest SAA concentrations had lower serum TIBC values. These findings indicate that inflammation is the major factor responsible for alterations in iron analytes in diseased manatees. Consequently, hypoferraemia may be used as supportive evidence of inflammatory disease in manatees (unless haemorrhage is also present). A decision threshold of ≤13.8 μmol/l was determined for hypoferraemia using receiver operating curve analysis. Based on studies in man and domestic animals, iron therapy is unnecessary for manatees with hypoferraemia associated with inflammation and has the potential for causing tissue damage and increased susceptibility to bacterial infections.

Impact of moral injury on the lives of UK military veterans: a pilot study

Introduction

Research suggests that moral injury (MI) in US veterans is associated with poor psychological outcomes and disruption in functioning. However, little is known about how MI may impact UK Armed Forces (AF) veterans. This study aimed to explore the impact of MI on veteran psychological well-being and functioning.

Methods

Six veterans identified as having had exposure to MI and four clinicians who treated veterans with MI were recruited from a UK charitable organisation which provides psychological care for veterans. Data were analysed using thematic analysis.

Results

MI was perceived to cause substantial psychological distress in this sample. Our data suggest that some veterans held extremely negative self-appraisals which appeared to contribute towards and maintain their distress. Issues relating to spirituality following MI were thought to be infrequent; however, a loss of faith was perceived by clinicians to be more common in morally injured veterans than heightened spiritual/religious views. Several difficulties relating to employment were described, including increased trouble coping with occupational stress and authority figures. Interpersonal difficulties were frequently reported, with withdrawal from others often leading to relationship breakdown with spouses and children.

Conclusion

This study provides some of the first evidence of the impact of MI on UK AF veterans’ psychological, spiritual, social and day-to-day functioning all of which would pose challenges to clinicians aiming to manage such difficulties. These findings highlight several gaps in existing care provision for morally injured veterans, including addressing issues related to spirituality, employment and family functioning, which could ultimately improve veteran well-being.

Relationship between obesity and health problems in help-seeking military veterans

Background

UK Armed Forces (UK AF) veterans may be particularly vulnerable to obesity and its comorbid physical and mental health problems.

Aim

To examine the relationship between body mass index (BMI), physical health problems, mental health disorders and sociodemographic characteristics in UK AF veterans engaged in psychological treatment.

Methods

Information regarding veteran BMI, demographic characteristics, physical health conditions and mental health problems was collected and analysed using univariate and multivariate regression analyses. Rates of veteran obesity were also compared with the UK general population.

Results

Of the 384 help-seeking veterans, 37.5% (n=151) were overweight (BMI 26–30) and 35.5% (n=143) were obese. Obesity in help-seeking male veterans was two to four times higher than that of the general population of UK. Higher scores on measures of anger and common mental health problems were significantly associated with greater BMI. Problems with physical systemic functioning and mobility were also significantly associated with greater BMI.

Conclusions

The results indicate that treatment-seeking UK AF veterans exhibit higher levels of obesity compared with the general population, and clinically significant physical and mental comorbidities. The findings highlight a need for mental health services to offer treatments that effectively integrate physical and mental healthcare in the treatment of people with mental health problems.

A latent profile analysis of PTSD symptoms among UK treatment seeking veterans

Background: Significant numbers of individuals leave the military and experience symptoms of posttraumatic stress disorder (PTSD). Veterans with PTSD symptoms rarely experience them in isolation, more commonly they are co-morbid with a range of other difficulties. Objective: Latent profile analysis (LPA) was used to explore the heterogeneity of PTSD symptom presentation. Following this, regression analysis was used to examine variables that predicted membership to the identified PTSD profiles. Methods: Data on childhood adversity, socio-demographic characteristics and mental health outcomes was collected from 386 male veterans who had engaged with mental health services in the UK. Results: LPA identified a six-profile model to best describe the sample. There was a Low symptom profile, a Severe symptom profile and four Moderate symptom profiles. The Severe symptom profile was the largest one, accounting for 37.57% of the sample. Five out of the six profiles had mean PTSD scores above the cut-off for probable PTSD. Higher rates of common mental health difficulties were associated with more symptomatic profiles. Discussion: As the vast majority of veterans met criteria for probable PTSD, the finding of six different profiles differing primarily quantitatively, but to some extent also qualitatively, suggests the importance of moving away from a 'one-size fits all' approach when it comes to treatments, towards developing interventions that are tailored to meet the specific PTSD and co-morbid symptoms profiles.

Abstract 408: Evidence of DLL4, NNAT, and SLC35C2 in suppression of breast cancer initiation, growth, and metastasis

Breast cancer affects 1 in 8 women, resulting in 40,000 deaths annually. In most cases, a single cause of breast cancer cannot be found, but rather multiple environmental and genetic factors contribute to overall disease susceptibility. This, combined with complex gene interaction in both malignant tumor cells and nonmalignant tumor microenvironment (TME) cells, poses significant challenges in sifting through the many variants that contribute to the ~31% of breast cancer risk that is heritable. Here, we narrowed the regions associated with breast cancer risk on rat chromosome 3 (RNO3) by introgressing portions of RNO3 derived from the BN rat (protective strain) onto the genomic background of the SS rat (susceptible strain). These SS.BN3 congenics were then phenotyped for DMBA-induced mammary tumor incidence, latency, and multiplicity, which revealed two loci in close proximity that contribute to mammary tumor risk: chr3:95-130Mb (QTL1) and chr3: 154-177Mb (QTL2). By comparing these data with a previous study (Flister et al. Breast Cancer Res Treat. 2017 Aug;165(1):53-64.), we concluded that QTL1 is dependent on the host TME, whereas QTL2 directly modifies breast tumorigenesis and cancer cell proliferation. By combining the congenic mapping studies with genomic and transcriptomic sequencing, and functional analysis, we have now localized the top three candidate modifiers on RNO3: DLL4 (QTL1; TME modifier), NNAT (QTL2; cancer cell modifier), and SLC35C2 (QTL2; cancer cell modifier). Collectively, these data demonstrate the effects of several novel breast cancer modifiers, as well as highlight the potential interactions between modifiers of the malignant cancer cells and the nonmalignant host TME.

Risk factors of suicidal ideation in a population of UK military veterans seeking support for mental health difficulties

Background

Little has been reported regarding the risk factors of suicidal ideation in individuals once they have left the military in the UK. The aim of this paper was to explore the risk factors associated with suicidal ideation in a sample of treatment-seeking veterans.

Methods

Using a cross-sectional design, participants included veterans (n=144) seeking treatment from a national mental health charity in the UK. Individuals completed questionnaires regarding their military experiences, pre-enlistment factors and health. Data were then linked to risk assessments extracted from clinical records.

Results

After controlling for relevant variables, suicidal ideation was significantly higher in veterans who were unemployed (OR 8.01; 95% CI 1.79 to 35.80), were early service leavers (OR 8.46; 95% CI 2.21 to 32.35) and those with a history of childhood adversity (OR 6.92; 95% CI 2.10 to 22.82). In addition, taking longer than 5 years to seek help was associated with a reduced risk of suicidal ideation (OR 0.10; 95% CI 0.06 to 0.87). There was no association between health outcomes and suicidal ideation.

Conclusions

Risk factors associated with suicidal ideation in this sample of veterans included: being unemployed, an early service leaver, taking less than 5 years to seek help and experiencing preservice adversity.

Can 5-methylcytosine analogues with extended alkyl side chains guide DNA methylation?

5-Methylcytosine (^MeC) is an endogenous modification of DNA that plays a crucial role in DNA-protein interactions, chromatin structure, epigenetic regulation, and DNA repair. ^MeC is produced via enzymatic methylation of the C-5 position of cytosine by DNA-methyltransferases (DNMT) which use S-adenosylmethionine (SAM) as a cofactor. Hemimethylated CG dinucleotides generated as a result of DNA replication are specifically recognized and methylated by maintenance DNA methyltransferase 1 (DNMT1). The accuracy of DNMT1-mediated methylation is essential for preserving tissue-specific DNA methylation and thus gene expression patterns. In the present study, we synthesized DNA duplexes containing MeC analogues with modified C-5 side chains and examined their ability to guide cytosine methylation by the human DNMT1 protein. We found that the ability of 5-alkylcytosines to direct cytosine methylation decreased with increased alkyl chain length and rigidity (methyl > ethyl > propyl ∼ vinyl). Molecular modeling studies indicated that this loss of activity may be caused by the distorted geometry of the DNA-protein complex in the presence of unnatural alkylcytosines.

Mental health of refugees in inner-London

What follows is an attempt to describe the provision of mental health care for refugees (including asylum seekers). Our views are based on our work with refugees in inner-London and on consultation with service providers.

Death of a hospital

The life of an institution may come to an end. The closure of a large mental hospital is an event of great emotional importance analogous to the death of an individual. Man has developed a set of rituals to help him cope with emotional turmoil released by bereavement. Since the death of an institution is not common the need for mourning rituals is not so generally acknowledged. We describe a ceremony to mark the closure of Cane Hill Hospital, Surrey.

Characteristics of prisoners with intellectual disabilities

BACKGROUND

Previous studies have found high rates of intellectual disabilities (ID) in prison. However, little is understood about prisoners with ID. This study aimed to identify prisoners with ID and compare their characteristics with prisoners without neurodevelopmental disorders with regard to demographic profile, mental health, suicide risk and offences.

METHOD

This was a descriptive, cross-sectional study carried out using face-to-face interviews with 240 participants in a London Category C prison. Standardised tools were used to assess prisoners for ID and mental disorder.

RESULTS

The study identified 18 prisoners as having ID. Participants with ID were less likely to be from a black or minority ethnic background, be over 35 years of age or have any qualifications. They were more likely to have been single, homeless or unemployed before coming into prison. Prisoners with ID were significantly more likely to have mental health problems and 25% had thought about suicide in the last month and 63% had attempted suicide in the past. Prisoners with ID were also more likely to be housed in the vulnerable prisoners' wing and significantly more likely to have committed robbery than other prisoners.

CONCLUSIONS

The findings confirm the presence of significant numbers of people with ID with high levels of mental illness in a male prison. Services across the CJS are required for this group, specifically, there is a need for raised awareness among those working in prison about ID and improved skills to recognise offenders with ID and address major gaps in current healthcare provision in prison.

Innovative Strategies for the Management of a Massive Neonatal Rhabdomyoma

Rhabdomyomas are histologically benign tumors known to be associated with tuberous sclerosis. The natural history predicts the majority of tumors to be asymptomatic and regress within the first year of life. We describe a neonate presenting on day 1 of life with cardiovascular collapse secondary to a massive rhabdomyoma. Surgical resection was excluded due to the extensive nature of the lesion and oral sirolimus, a mammalian target of rapamycin inhibitor, was commenced to promote tumor regression. The patient developed intractable arrhythmias requiring extracorporeal life support during therapy.

Exploring the health risks of help-seeking military veterans living in different parts of the UK

Background

Little is known about the mental and physical health differences of treatment-seeking military veterans across the different nations that make up the UK. The aim of this research was to explore potential health differences in order to support better service planning.

Methods

A random cross-sectional sample of treatment-seeking veterans residing in England, Scotland, Wales and Northern Ireland was identified from a national mental health charity. 403 veterans completed a questionnaire highlighting their demographics, mental health and physical health difficulties. The data were analysed using a multinomial logistic regression with England as the baseline comparison.

Results

Help-seeking veterans residing in Northern Ireland tended to be older, have experienced less childhood adversity, joined the military after the age of 18 and took longer to seek help. Additionally, veterans from Northern Ireland had higher levels of obesity, sensory, mobility and systemic problems and a greater number of physical health conditions. Scottish and Welsh veterans had a higher risk of smoking and alcohol misuse. No differences were found in mental health presentations.

Conclusion

The findings from this paper suggest that a greater focus needs to be placed on treating physical problems in Northern Irish veterans. Alcohol misuse should be addressed in more detail in treatment programmes, particularly in Scotland and Wales. As few differences were found in the mental health presentations, this suggests that standardised services are adequate.

Abstract 348: Interleukin 13 is Required for Neonatal Heart Regeneration

Shortly after birth neonatal mice can fully regenerate their hearts, but this potential is lost in the first week of life. Cell cycle entry of existing cardiomyocytes is thought to be an essential mechanism enabling neonatal mouse heart regeneration. In previous studies we found that the cytokine interleukin 13 (IL13) was a an upstream regulator of differentially expressed gene networks during neonatal heart regeneration and stimulated cell cycle activity of cultured rat cardiomyocytes, suggesting that this factor might be important in neonatal heart regeneration in vivo . In the present study, we subjected wildtype and IL13 knockout mice to ventricular apical resection at one day of age and assessed heart regeneration 21 days post resection (dpr). Compared to wildtype controls, IL13 knockout mice failed to regenerate their hearts as determined by extensive scar formation at the ventricular apex. To gain insight into the mechanism of impaired regeneration, we quantified cardiomyocyte proliferation and expression of macrophage markers at 7 dpr. We found no difference in gene expression of macrophage markers in IL13 knockout mice compared to wildtype. Interestingly, IL13 knockout mice demonstrate a significant increase cardiomyocyte cell cycle activity as determined by phosphorylated Histone H3 (pH3) staining. This seemingly contradictory result appears to be due to an underlying developmental defect in IL13 knockout hearts. Cardiomyocytes in IL13 knockout mice appeared large and disorganized. Cardiomyocytes from IL13 knockout unoperated mice showed decreased pH3 staining and had increased expression marker of hypertrophic growth such as Nppb and Nppa. Histologically, hearts from IL13 knockout mice appeared to have a dilated cardiomyopathy phenotype. Collectively our data suggests that during heart development IL13 influences proliferative versus hypertrophic growth. We surmise that following neonatal apical resection in IL13 knockout mice the significant increase in cardiomyocyte proliferation is a compensatory attempt to repair the injury, but the underlying cardiomyocyte phenotype inhibits complete regeneration. These data are the first to report a role for IL13 in normal heart development and neonatal heart regeneration.
