What is the role of doctors in respect of suspects with mental health and intellectual disabilities in police custody?

People with severe mental illness and intellectual disabilities are overrepresented in the criminal justice system worldwide and this is also the case in Ireland. Following Ireland's ratification of the United Nations' Convention on the Rights of People with Disabilities in 2018, there has been an increasing emphasis on ensuring access to justice for people with disabilities as in Article 13. For people with mental health and intellectual disabilities, this requires a multi-agency approach and a useful point of intervention may be at the police custody stage. Medicine has a key role to play both in advocacy and in practice. We suggest a functional approach to assessment, in practice, and list key considerations for doctors attending police custody suites. Improved training opportunities and greater resources are needed for general practitioners and psychiatrists who attend police custody suites to help fulfill this role.

European Society of Cardiology quality indicators for the prevention and management of cancer therapy-related cardiovascular toxicity in cancer treatment

AIMS

To develop quality indicators (QIs) for the evaluation of the prevention and management of cancer therapy-related cardiovascular toxicity.

METHODS AND RESULTS

We followed the European Society of Cardiology (ESC) methodology for QI development which comprises (i) identifying the key domains of care for the prevention and management of cancer therapy-related cardiovascular toxicity in patients on cancer treatment, (ii) performing a systematic review of the literature to develop candidate QIs, and (iii) selecting of the final set of QIs using a modified Delphi process. Work was undertaken in parallel with the writing of the 2022 ESC Guidelines on Cardio-Oncology and in collaboration with the European Haematology Association, the European Society for Therapeutic Radiology and Oncology and the International Cardio-Oncology Society. In total, 5 main and 9 secondary QIs were selected across five domains of care: (i) Structural framework, (ii) Baseline cardiovascular risk assessment, (iii) Cancer therapy related cardiovascular toxicity, (iv) Predictors of outcomes, and (v) Monitoring of cardiovascular complications during cancer therapy.

CONCLUSION

We present the ESC Cardio-Oncology QIs with their development process and provide an overview of the scientific rationale for their selection. These indicators are aimed at quantifying and improving the adherence to guideline-recommended clinical practice and improving patient outcomes.

Prediction of anthracycline-induced cardiotoxicity as assessed by global longitudinal strain in women with early breast cancer: insights from the PRADA trial

Background

Early recognition of anthracycline-induced cardiotoxicity is essential to prevent and treat left ventricular dysfunction before permanent damage ensues. Echocardiographic global longitudinal strain (GLS) may be a more sensitive indicator of decline in left ventricular systolic function than measurement left ventricular ejection fraction (LVEF). Many factors have been associated with cardiotoxicity defined by LVEF criteria, but less is known about predictors of early and late cardiotoxicity expressed as GLS.

Objective

The purpose of this study was to identify factors associated with cardiotoxicity, defined as absolute GLS <18% (a) after completion of anthracycline treatment and (b) at extended follow up after completion of adjuvant therapy for early breast cancer.

Methods

120 women with early breast cancer undergoing adjuvant treatment with anthracyclines and/or trastuzumab, were included in the PRADA (PRevention of cArdiac Dysfunction during Adjuvant breast cancer) trial and randomized in a 2x2 factorial fashion to concomitant treatment with candesartan cilexetil, metoprolol succinate or matching placebo. Serial measurements of cardiovascular biomarkers (high sensitivity cardiac troponin I (hs-cTnI), B-type natriuretic peptide (BNP) and Galectin-3), cardiovascular magnetic resonance and echocardiography were performed at baseline, after anthracycline treatment and at extended follow-up median 23 months (interquartile range 21–28 months) after initiation of adjuvant therapy for early breast cancer. To identify potential predictors of cardiotoxicity defined by GLS criteria, associations between demographic, clinical, cancer therapy and biochemical and imaging biomarker data were evaluated by logistic regression analysis.

Results

89 patients had GLS measurements performed at baseline, 87 at completed anthracycline therapy and 81 at extended follow-up. An overall decline in absolute GLS of 0.75% was observed at extended follow-up. One patient had absolute GLS <18 prior to anthracycline therapy whereas, 7 out of 87 (8.0%) and 7 out of 81 (8.6%) patients had GLS levels <18 after completion of anthracycline treatment and at extended follow up, respectively. Variables associated with absolute GLS <18% after anthracycline treatment and at extended follow-up are summarized in Tables 1a and 1b.

Conclusion

In this subanalysis of the PRADA trial, higher age, higher hs-cTnI, lower LVEF, lower E' and higher GLS at baseline predicted subsequent reduced systolic function expressed as reduced absolute GLS after anthracycline treatment. Higher age, hypertension, higher body mass index and higher hs-cTnI concentrations predicted absolute GLS <18 at extended follow up. Assessment of cardiac troponin I, cardiac imaging biomarkers and patient age may assist in the identification of patients at risk for developing cardiotoxicity.

Rationale and design of the PRevention of cArdiac Dysfunction during Adjuvant breast cancer therapy (PRADA II) trial: a randomized, placebo-controlled, multicenter trial

Background

Recent advances in the treatment algorithms of early breast cancer have markedly improved overall survival. However, anthracycline- and trastuzumab-associated cardiotoxicity may lead to dose-reduction or halt in potentially life-saving adjuvant cancer therapy. Early initiated neurohormonal blockade may prevent or attenuate the cardiotoxicity-induced reduction in cardiac function, but prior studies have been inconclusive. The angiotensin receptor-neprilysin inhibitor sacubitril/valsartan has been shown to be superior to traditional treatment in heart failure with reduced ejection fraction, but its cardioprotective effects in the cardio-oncology setting remains to be tested.

Objective

To assess if sacubitril/valsartan given concomitantly with early breast cancer treatment regimens including anthracyclines, with or without trastuzumab, may prevent cardiac dysfunction.

Methods

PRADA II is a randomized, placebo-controlled, double blind, multi-center, investigator-initiated clinical trial. Breast cancer patients from four university hospitals in Norway, scheduled to receive (neo-)adjuvant chemotherapy with epirubicin independently of additional trastuzumab/pertuzumab treatment, will be randomized 1:1 to sacubitril/valsartan or placebo. The target dose is 97/103 mg b.i.d. The patients will be examined with cardiovascular magnetic resonance (CMR), echocardiography, circulating cardiovascular biomarkers and functional testing at baseline, at end of anthracycline treatment and following 18 months after enrolment. The primary outcome measure of the PRADA II trial is the change in left ventricular ejection fraction (LVEF) by CMR from baseline to 18 months. Secondary outcomes include change in LV function by global longitudinal strain by CMR and echocardiography and change in circulating cardiac troponin concentrations.

Results

The study is ongoing. Results will be published when the study is completed.

Conclusion

PRADA II is the first randomized, placebo-controlled study of sacubitril/valsartan in a cardioprotective setting during (neo-)adjuvant breast cancer therapy. It may provide new insight in prevention of cardiotoxicity in patients receiving adjuvant or neo-adjuvant therapy containing anthracyclines. Furthermore, it may enable identification of patients at higher risk of developing cardiotoxicity and identification of those most likely to respond to cardioprotective therapy.

Trial registration

The trial is registered in the ClinicalTrials.gov registry (identifier NCT03760588). Registered 30 November 2018.

To assess the confidence levels of psychiatrists in physical healthcare competencies in one irish region, and to explore whether confidence was related to learning opportunities

Introduction

The bi-directional relationship between mental and physical illness is well established. Therefore, in order to lower the already high mortality rates associated with psychiatric disorders, physical health issues must be closely monitored in this population [1,2]. A recent Lancet commission highlights emerging strategies and recommendations for improvement of physical health outcomes in patients with chronic mental disorders. These strategies involve better integration of physical and mental health care, combined with broader implementation of lifestyle interventions to reduce elevated cardiometabolic risk and attenuate medication side-effects [3].

Objectives

To assess psychiatrists’ confidence levels in physical healthcare competencies; to explore whether confidence was related to learning opportunities.

Methods

Physical healthcare learning objectives were extracted from the Irish College of Psychiatrists’ training curriculum. An electronic questionnaire was sent to 50 psychiatrists in one Irish healthcare region with a catchment area of c. 450,000. Participants had to rate confidence levels for each competency on a five-point Likert scale and the availability of learning opportunities for attaining each competency.

Results

66% response rate was achieved. A majority reported confidence in cardiovascular examination, interpreting blood results and evaluating comorbidities. A minority reported confidence in interpreting imaging, electrocardiograms and recognising medical emergencies. This corresponds to a relative paucity of learning opportunities.

Conclusions

Clinical implication Programmes for trainee doctors and CME opportunities for consultant psychiatrists would benefit from an emphasis on physical health examination and modules on interpreting investigations and the recognition of medical emergencies.

1124 Central Sleep Apnea and Traumatic Brain Injury: A NIDILRR and VA TBI Model System Study

Introduction

Sleep-related breathing disorders are common after TBI. To date, two single site studies have reported divergent findings in post-TBI patients with one reporting predominantly obstructive sleep apnea (OSA, Holcomb et al., 2016) and the other central sleep apnea (CSA, Webster and Bell, 1998). The purpose of this analysis is to explore prevalence, demographics, and injury characteristics of patients with a clinical diagnosis of CSA in a recently-completed multicenter comparative-effectiveness trial during inpatient rehabilitation following moderate to severe TBI.

Methods

Participants in a six-center diagnostic comparative effectiveness trial underwent Level-1 polysomnography (PSG) during inpatient rehabilitation for TBI. Studies were scored at a centralized scoring center by one of two certified PSG technicians with final interpretation by a board-certified sleep medicine physician.

Results

21 of 248 (8.5%) participants evidenced elevated CSA indices >5. Predominant CSA was rare (n=3 [1.2%], age range: 36-59; 100% male; 33-52 days post-TBI). One participant was on opioid, anti-depressant and antiepileptic drugs, one was on an antiepileptic, and another was on an opioid. PAP therapy was not initiated during PSG thus there was no treatment-emergent CSA. All had a central apnea-hypopnea index (AHI) in the moderate to severe range (29-49). Two out of the three had a GCS <8 and one participant had a GCS of 14.

Conclusion

In this multi-center clinical trial, predominant CSA was rare. The common practice of reducing polypharmacy in order to minimize sedation and optimize mental status in specialized inpatient brain-injury rehabilitation programs may contribute to the low CSA incidence in this cohort. Attention to medication side-effects and their influence on sleep-related breathing should be routinely considered.

Epilepsy in Irish psychiatric inpatient settings

Aims To ascertain epilepsy prevalence in Irish psychiatric inpatient units and compliance with care planning guidelines. Methods Case records were reviewed in seven psychiatric inpatient units. Results The prevalence of epilepsy across seven psychiatric inpatient units (n=9/267) was three times that of general population estimates. Minimal data was recorded pertaining to seizure type (n=1,11.1%), triggers (n=2,22.2%), clinical investigations relating to epilepsy (n=2,22%) and no epilepsy risk assessments were recorded (n=0,0%). Conclusions The introduction of appropriate care plans is needed to optimise physical and mental wellbeing of those with epilepsy in psychiatric units.

Diversion of Mentally Ill Offenders from the Criminal Justice System in Ireland: Comparison with England and Wales

AIM

It is generally accepted that certain people who are mentally ill and have contact with the criminal justice system should be diverted to psychiatric care rather than imprisoned. We sought to comment on priorities relating to the development of diversion services in Ireland through comparison with developments in a neighbouring jurisdiction.

METHODS

A comparative review was undertaken in relation to the provision for psychiatric diversion across the offender pathway in Ireland and England and Wales. This included legal and service related considerations.

RESULTS

In both jurisdictions, services show significant geographical variability. While developments in England and Wales have focussed on the broader offender pathway, diversion services in Ireland are chiefly linked to imprisonment. There is little or no specialist psychiatric expertise available to Gardai in Ireland. Prison In-reach and Court Liaison Services (PICLS) are developing in Ireland but expertise and resourcing are variable geographically. There is a lack of Intensive Care Regional Units (ICRU) in Ireland, in sharp contrast with the availability of Intensive Care and Low Secure Units in England and Wales. There is limited scope to divert to hospital at sentencing stage in the absence of a "hospital order" provision in Irish legislation.

CONCLUSIONS

Three areas in the development of Irish diversion services should be prioritised. Firstly, the provision of advice and assistance to Gardai at arrest, custody and initial court hearing stages. Secondly, legislative reform to remove barriers to diverting remand prisoners and facilitating hospital disposal on sentencing. Thirdly, an urgent need to develop of ICRU's (Intensive Care Regional Units) to facilitate provision of appropriate care by local mental health services.

Prospective validation of a novel renal activity index of lupus nephritis

Objectives The renal activity index for lupus (RAIL) score was developed in children with lupus nephritis as a weighted sum of six urine biomarkers (UBMs) (neutrophil gelatinase-associated lipocalin, monocyte chemotactic protein 1, ceruloplasmin, adiponectin, hemopexin and kidney injury molecule 1) measured in a random urine sample. We aimed at prospectively validating the RAIL in adults with lupus nephritis. Methods Urine from 79 adults was collected at the time of kidney biopsy to assay the RAIL UBMs. Using receiver operating characteristic curve analysis, we evaluated the accuracy of the RAIL to discriminate high lupus nephritis activity status (National Institutes of Health activity index (NIH-AI) score >10), from low/moderate lupus nephritis activity status (NIH-AI score ≤10). Results In this mixed racial cohort, high lupus nephritis activity was present in 15 patients (19%), and 71% had proliferative lupus nephritis. Use of the identical RAIL algorithm developed in children resulted in only fair prediction of lupus nephritis activity status of adults (area under the receiver operating characteristic curve (AUC) 0.62). Alternative weightings of the six RAIL UBMs as suggested by logistic regression yielded excellent accuracy to predict lupus nephritis activity status (AUC 0.88). Accuracy of the model did not improve with adjustment of the UBMs for urine creatinine or albumin, and was little influenced by concurrent kidney damage. Conclusions The RAIL UBMs provide excellent prediction of lupus nephritis activity in adults. Age adaption of the RAIL is warranted to optimize its discriminative validity to predict high lupus nephritis activity status non-invasively.

Lung ultrasound in the ICU: from diagnostic instrument to respiratory monitoring tool

Imaging has greatly contributed to the understanding of lung disease in the critically ill and currently serves as a tool to diagnose lung pathology, monitor its course, and guide clinical management. Lung ultrasound is a real-time imaging modality that is simple, non-invasive, potentially ubiquitous, and free of ionizing radiation. Its increasing popularity and supporting research data substantiate its role as an emerging technique for bedside chest imaging in critical care. Furthermore, the International Consensus Conference on Lung ultrasound (ICC-LUS) promoted by the World Interactive Network Focused on Critical UltraSound (WINFOCUS) recently standardized the nomenclature and technique for lung ultrasound, and provided recommendations supporting its use in clinical practice. While the utility of lung ultrasound in the emergency setting is unquestioned, its potential role in the more complex and resource-rich intensive care environment is still under investigation. The purpose of this paper was to describe current and potential uses of lung ultrasound in the specific setting of adult intensive care, with an emphasis on respiratory monitoring, and to provide a framework for the practical application of this tool at the bedside.

Assessment of atherosclerosis by carotid intimomedial thickness in patients with rheumatoid arthritis

OBJECTIVES

To determine the prevalence of subclinical (asymptomatic) atherosclerosis in patients with rheumatoid arthritis (RA) and to study the variables affecting such an occurrence.

METHODS

Case control study which included 100 patients with RA having disease duration more than 5 years and 100 healthy age and sex matched controls. Cases and controls symptomatic for atherosclerosis or having traditional risk factors for atherosclerosis were excluded. Both cases and controls were subjected to carotid ultrasound examination in addition to detailed history and physical examination.

RESULTS

The study population (both cases and controls) included 94 females and 6 males. The mean age of cases and controls was similar (44.06 +/- 11.32 years and 44.1 +/- 11.52 years). The mean disease duration was 155.04 +/- 48.8 months. The mean carotid intimo-medial thickness (CIMT) of the RA patients (0.519 +/- 0.18 mm) was significantly greater than the controls (0.387 +/- 0.085). Age and disease duration were the only factors found to significantly affect CCIMT. RA patients had higher prevalence of carotid plaques (21%) compared to controls (1%). Erosions on hand radiographs were the only significant predictor of plaques in patients with RA.

CONCLUSION

Patients with RA exhibit premature atherosclerosis by way of increased CIMT and carotid plaques when compared to age and sex matched controls.

Comparison of echo and MRI in the imaging evaluation of intracardiac masses

We compared the efficacy of echocardiography (ECHO) and magnetic resonance imaging (MRI) for evaluating intracardiac masses. Over an 8-yr period, 28 patients, 21 males, 7 females, 16 days-60 years of age (mean 25 years) with a suspected intracardiac mass on ECHO (transthoracic in all; transesophageal in 9) underwent an MRI examination. Five patients had a contrast-enhanced MRI. ECHO and MRI were compared with respect to their technical adequacy, ability to detect and suggest the likely etiology of the mass, and provide additional information (masses not seen with the other technique, inflow or outflow obstruction, and intramural component of an intracavitary mass). With MRI, the image morphology (including signal intensity changes on the various sequences) and extracardiac manifestations were also evaluated. The diagnosis was confirmed by histopathology in 18, surgical inspection in 4, by follow- up imaging on conservative management in 5, and by typical extracardiac manifestations of the disease in 1 patient. Fifteen (54%) patients had tumors (benign 12, malignant 3), 5 had a thrombus or hematoma, and 4 each had infective or vascular lesions. Thirty-four masses (13 in ventricle, 11 septal, 7 atrial, 2 on valve and 1 in pulmonary artery) were seen on MRI, 28 of which were detected by ECHO. Transthoracic ECHO (TTE) and MRI were technically optimal in 82% and 100% of cases, respectively. Nine patients needed an additional transesophageal ECHO (TEE). Overall, MRI showed a mass in all patients, whereas ECHO missed it in 2 cases. In cases with a mass on both modalities, MRI detected 4 additional masses not seen on ECHO. MRI suggested the etiology in 21 (75%) cases, while the same was possible with ECHO (TTE and TEE) in 8 (29%) cases. Intramural component, extension into the inflow or outflow, outflow tract obstruction, and associated pericardial or extracardiac masses were better depicted on MRI. We conclude that MRI is advantageous over a combination of TTE and TEE for the detection and complete morphological and functional evaluation (hemodynamic effects) of cardiac masses.

Bilateral eventration of the diaphragm with perforated gastric volvulus in an adolescent

Bilateral congenital eventration of the diaphragm almost uniformly presents in infancy with respiratory compromise and is associated with a high mortality rate. Delayed presentation of diaphragmatic eventration in older children and adults may be associated with acute gastric volvulus. Thus, any patient with abdominal pain, vomiting, or nonspecific gastrointestinal symptoms in association with abnormal diaphragmatic findings on chest x-ray should undergo further diagnostic workup with upper gastrointestinal series or computed tomography (CT) scan. Treatment of gastric volvulus requires immediate surgical repair to prevent subsequent necrosis and perforation. The authors describe a case report of bilateral congenital diaphragmatic eventration complicated by a perforated gastric volvulus in a 13-year-old boy. Emergent reduction of the volvulus, closure of the perforated stomach, plication of the diaphragm, and placement of gastrostomy was performed successfully.

Effect of starvation and insulin-induced hypoglycemia on oxidative stress scavenger system and electron transport chain complexes from rat brain, liver, and kidney

Considerable evidence suggests that oxidative stress plays an important role in tissue damage associated with hypoglycemia and other metabolic disorders. The altered brain neurotransmitters metabolism, cerebral electrolyte contents, and impaired blood-brain barrier function may contribute to CNS dysfunction in hypoglycemia. The present study elucidates the effect of starvation and insulin-induced hypoglycemia on the free radical scavanger system--reduced glutathione (GSH) content, glutathione S-transferase (GST), glutathione peroxidase (GPx), glutathione reductase (GR), gamma-glutamyl transpeptidase (gamma-GTP), gamma-glutamyl cystein synthetase (gamma-GCS), catalase and superoxide dismutase (SOD), and mitochondrial electron transport chain (ETC) complexes I-IV from three different regions of rat brain, namely cerebral hemispheres (CH), cerebellum (CB), and brainstem (BS). Peripheral organs, such as liver and kidney, were also studied. Significant changes in these enzymic activities were observed. The analysis of such alterations is important in ultimately determining the basis of neuronal dysfunction during metabolic stress conditions, such as hypoglycemia, and also defining the nature of these changes may help to develop therapeutic means to cure metabolically stressed tissues.

Mutant forms of spectrin alpha-subunits in hereditary elliptocytosis

Two variant spectrins have been described in hereditary elliptocytosis (HE) and pyropoikilocytosis (HPP). Both are characterized by increased susceptibility of the alpha I (N-terminal) 80-kD domain to mild tryptic digestion, yielding peptides of 46-50 or 65-68 kD (T50a and T68 in our terminology). In this report we add a third unstable spectrin alpha I domain found in three kindreds with HE; alpha IT80 in this type of spectrin is cleaved by mild tryptic digestion to a 50-kD peptide (T50b) distinguished from T50a by its more basic isoelectric point. All three spectrins show impaired self-association to form oligomers. Intermediate tryptic peptides of the three unstable alpha I domains from HE spectrins were characterized by monoclonal immunoblotting and I125 limit peptide mapping and affinity purified using polyclonal anti-alpha IT80. Partial amino acid sequences of alpha I domain peptides were obtained from two unrelated patients for each of the three variant spectrins. T50a results from cleavage at arginine 250 or lysine 252 of alpha IT80; a proline replaced the normal leucine or serine at residues 254 and 255, respectively. T50b and a 19-kD peptide result from cleavage at arginine 462 or arginine 464; a proline replaced the normal residue 465 (in T19b) in one of the two patients studied. T68 results from cleavage at arginine 131. In both 68-kD peptides examined, a leucine is inserted at residue 150. The relationship of the sequence changes to the new tryptic cleavages, to the current model of alpha I domain structure, and to defective spectrin self-association is discussed.
