- Abstract
Objective: To explore the relationship between blood pressure (BP) variability and perinatal outcomes., Study Design: This was a retrospective study of 996 pregnant women with hypertension/risk factors for hypertension in pregnancy. BP variability was calculated by visit-to-visit standard deviation (SD) and mean difference (MD). Logistic regression explored the relationship between BP variability and perinatal outcome, adjusting for confounders., Main Outcome Measures: Correlation between BP variability and i) fetal growth restriction (FGR) and ii) preterm birth (PTB)., Results: FGR and PTB complicated 128/996 (13 %) and 233/996 (23 %) pregnancies. At visit 1, 61 (6 %) women were taking labetalol, 125 (13 %) were taking calcium channel blockers and 780 (78 %) were not taking antihypertensives. Increased BP variability was associated with FGR and PTB. These relationships persisted after adjustment for number of antihypertensives, pre-pregnancy BP, BMI, ethnicity and previous FGR for systolic but not diastolic BP variability (adjusted OR for FGR: 1.16 [95 % C.I. 1.03-1.30]; PTB: 1.16 [1.05-1.29]). However, statistical significance was lost after adjustment for maximum BP. Nifedipine was associated with increased BP variability, compared with labetalol, despite adjustment for ethnicity and pre-existing hypertension (adjusted difference: 1.93 mmHg [0.13-3.73], p = 0.04)., Conclusions: Increased visit-to-visit systolic but not diastolic BP variability is associated with adverse perinatal outcomes. Nevertheless, it is unclear whether BP lability directly influences perinatal outcome, or merely reflects peak BP. The difference in BP variability between antihypertensives may reflect varying effectiveness or factors influencing antihypertensive choice. Prospective research is needed to investigate any potential link between antihypertensive medications, BP variability and perinatal outcome., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2025 The Authors.

- Abstract
Background: The COVID-19 pandemic has affected the healthcare systems worldwide since the dawn of 2020. In March 2020, the United Kingdom government announced the first national lockdown which severely disturbed all National Health Service (NHS) healthcare elective services. Our aim is to assess the long-term impact of COVID-19 related disruption of NHS elective services on emergency major lower limb amputations (MLLAs)., Methods: Patients' data for emergency MLLA for critical limb-threatening ischemia and diabetic foot infections performed at Aberdeen Royal Infirmary was collected through Trakcare and divided into the control prepandemic group (April 2018-March 2020) and the pandemic group (April 2020-March 2022). The statistical analysis was conducted using the IBM SPSS software (v28.0.1.1 [14])., Results: A total of 358 patients underwent MLLA and 206 (57.5%) of these had diabetes mellitus. There was a 17% increase in the number of urgent referrals and every 1 in 5 of these finally underwent an amputation. There was an increase in the absolute number of Above- and Below-Knee amputations. There was a statistically significant increase by 33% in emergency MLLAs during the pandemic period (P < 0.05). A total of 165 postoperative deaths up to December 2022 were recorded with 30-day mortality rate of 7.26% (n = 26)., Conclusions: NHS vascular management groups should update themselves with evolving technologies to optimize the care provided during future unprecedented times. Furthermore, more effective measures should also be implemented to avoid delayed presentations, which can potentially lead to higher rates of major limb amputations., (Copyright © 2024 Elsevier Inc.

- Abstract
Objectives: Abdominal aortic aneurysms (AAAs) demonstrating hostile neck anatomy (HNA) are associated with increased perioperative risk and mortality. A number of these patients are not suitable for standard endovascular aneurysm repair (EVAR) and are high risk for open surgery. We present our experience with the first implantations in Scotland of a novel conformable aortic stent-graft designed to overcome some of the challenges of HNAs., Methods: From May 2018 to March 2022, 24 consecutive patients with non-ruptured AAAs demonstrating HNAs (neck length < 15 mm, or angulation > 60°) were treated with GORE Excluder Conformable AAA endoprosthesis (CLEVAR) (CEXC Device, W.L. Gore and Associates, Flagstaff, AZ, USA) at a Scottish vascular centre. We assessed clinical outcomes and technical success of CLEVAR during deployment, primary admission and the post-operative period at 3- and 12-month clinical follow-up alongside CT angiography., Results: Twenty-four patients (20 males, mean age 75.6) were included. Primary technical success of proximal seal zones and CLEVAR deployment (no type 1/3 endoleaks, no conversion to open repair, AAA excluded and patient leaving theatre alive) was achieved in 100% of patients. All patients were alive and clinically stable at 3- and 12-month follow-up. There were five patients requiring re-intervention; at the 3-month follow-up, one patient (4.2%) developed a type 1b endoleak requiring graft limb extension, one patient developed a right common femoral artery dissection requiring open repair and one patient required a limb extension of the right iliac limb due to risk of developing a type 1b endoleak. At the 12-month follow-up, two patients required embolization of type 2 endoleaks and no patients demonstrated type 1 or type 3 endoleaks. Conclusions: In-hospital and post-operative 3- and 12-month clinical and angiographic outcomes demonstrate safety and efficacy with CLEVARs in treating unruptured AAAs with HNA. Further research involving larger heterogenous sample sizes is warranted to determine long-term clinical outcomes., Competing Interests: Declaration of conflicting interestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: B.R is the BSET-CLEVAR trial local principal investigator for the North of Scotland.

- Abstract
Inferior mesenteric artery (IMA) aneurysms represent the minority of visceral aneurysm presentations. A 57-year-old female was admitted with a symptomatic IMA aneurysm secondary to atherosclerotic disease. She was treated with open excision which revealed a contained ruptured of a true aneurysm. This case highlights the challenges of an accurate preoperative diagnosis of IMA aneurysm and the correct position of the recent guidelines on visceral aneurysms issued by the Society of Vascular Surgery (SVS). more...

- Abstract
Purpose of the Research: This pilot study reports the feasibility of a future randomized controlled trial (RCT) investigating the effect of supported self-management through low-intensity psychological intervention in patients with peripheral arterial disease (PAD) resulting in claudication. The study protocol, measurement instrument, data collection, and analysis were evaluated. Clinical outcome measures include depression and anxiety scores, smoking cessation, activity (step count), weight, and quality of life. Both Quantitative and Qualitative data were collected to evaluate participant experience and the clinical impact of a supported self-management intervention delivered in a routine clinical setting., Methods: Participants received an initial one to one assessment with a health psychologist. Demographic data and baseline clinical outcome measures were recorded. These included Hospital Anxiety and Depression Scale score (HADS), health-related quality of life questionnaire (EQ-5D-3 L), number of cigarettes smoked daily, weight/BMI, and daily step count. Participants each received an activity tracker to record daily step count and were followed up weekly to provide psychological input, including goal setting, overcoming barriers, and preventing relapse. Quantitative data collection was scheduled at baseline, 3 and 6 months (final follow-up). At the final follow-up, participants provided qualitative feedback reflecting upon their experience of the intervention and its impact. Descriptive statistical analysis and simple paired samples t-test were employed in data evaluation., Results: The sample size was small (n = 30). Twenty-three participants were followed up to 6 months. Depression scores improved with statistical significance from baseline to 6-month follow-up. Eight participants stopped smoking (47% reduction); a further 9 greatly reduced their intake. A borderline statistically significant increase of daily step count was achieved between baseline and 6-month follow-up. In addition, positive weight loss trends were observed in a predominantly obese or overweight cohort. The qualitative feedback highlighted participants understood and embraced the information delivered regarding the importance of health behavior change. Participants were able to link tailored action plans with what mattered to them with the help of the Health Psychologist., Conclusion: This study embraces the contemporary ideology of enabling self-management of long-term conditions to improve clinical outcomes. As a pilot study, we have shown that an expanded, randomized controlled trial is both safe and feasible. A positive trend in clinical outcomes suggests this patient group may benefit from supported self-management through low-intensity psychological intervention, where other forms of early intervention have historically faltered., (Copyright © 2021 Society for Vascular Nursing.

- Abstract
Background: Despite their use in clinical practice, there is little evidence to support the use of therapist written goodbye letters as therapeutic tools. However, preliminary evidence suggests that goodbye letters may have benefits in the treatment of anorexia nervosa (AN)., Aims: This study aimed to examine whether therapist written goodbye letters were associated with improvements in body mass index (BMI) and eating disorder symptomology in patients with AN after treatment., Method: Participants were adults with AN (n = 41) who received The Maudsley Model of Anorexia Treatment for Adults (MANTRA) in a clinical trial evaluating two AN out-patient treatments. As part of MANTRA, therapists wrote goodbye letters to patients. A rating scheme was developed to rate letters for structure and quality. Linear regression analyses were used to examine associations between goodbye letter scores and outcomes after treatment., Results: Higher quality letters and letters that adopted a more affirming stance were associated with greater improvements in BMI at 12 months. Neither the overall quality nor the style of goodbye letters were associated with improvements in BMI at 24 months or reductions in eating disorder symptomology at either 12 or 24 months., Conclusions: The results highlight the potential importance of paying attention to the overall quality of therapist written goodbye letters in the treatment of AN, and adopting an affirming stance. more...

- Abstract
Anatomical variation may result in unexpected complications after fenestrated endovascular aneurysm repair (FEVAR). We report a 78-year-old gentleman who was admitted for elective FEVAR procedure for a juxtarenal abdominal aortic aneurysm. Three days post-operatively, he deteriorated clinically. Computed tomography (CT) angiogram showed small bowel ischaemia and a replaced right hepatic artery originating from superior mesenteric artery. A necrotic gallbladder found during laparotomy required cholecystectomy following small bowel resection that required a relook for anastomosis and drainage of bile collection. He had prolonged ICU stay requiring treatment for multiple organ dysfunction then spent 4 weeks in hospital. Following multidisciplinary team approach in management of his complications during post-operative phase, he recovered well enough for rehabilitation and discharge home. Surveillance CT aorta at 1 month and 6 months post FEVAR showed satisfactory FEVAR appearance with no endoleak., (Published by Oxford University Press and JSCR Publishing Ltd.

- Abstract
In anorexia nervosa (AN), motivational salience is attributed to illness-compatible cues (e.g., underweight and active female bodies) and this is hypothesised to involve dopaminergic reward circuitry. We investigated the effects of reducing dopamine (DA) transmission on the motivational processing of AN-compatible cues in women recovered from AN (AN REC, n = 17) and healthy controls (HC, n = 15). This involved the acute phenylalanine and tyrosine depletion (APTD) procedure and a startle eye-blink modulation (SEM) task. In a balanced amino acid state, AN REC showed an increased appetitive response (decreased startle potentiation) to illness-compatible cues (underweight and active female body pictures (relative to neutral and non-active cues, respectively)). The HC had an aversive response (increased startle potentiation) to the same illness-compatible stimuli (relative to neutral cues). Importantly, these effects, which may be taken to resemble symptoms observed in the acute stage of illness and healthy behaviour respectively, were not present when DA was depleted. Thus, AN REC implicitly appraised underweight and exercise cues as more rewarding than did HC and the process may, in part, be DA-dependent. It is proposed that the positive motivational salience attributed to cues of emaciation and physical activity is, in part, mediated by dopaminergic reward processes and this contributes to illness pathology. These observations are consistent with the proposal that, in AN, aberrant reward-based learning contributes to the development of habituation of AN-compatible behaviours., Competing Interests: The authors have declared that no competing interests exist. more...

- Abstract
Objective: Case formulation is a core component of many psychotherapies and formulation letters may provide an opportunity to enhance the therapeutic alliance and improve treatment outcomes. This study aimed to determine if formulation letters predict treatment satisfaction, session attendance, and symptom reductions in anorexia nervosa (AN). It was hypothesized that higher quality formulation letters would predict greater treatment satisfaction, a greater number of attended sessions, and greater improvement in eating disorder symptoms., Method: Patients were adult outpatients with AN (n = 46) who received Maudsley Anorexia Nervosa Treatment for Adults (MANTRA) in the context of a clinical trial. A Case Formulation Rating Scheme was used to rate letters for adherence to the MANTRA model and use of a collaborative, reflective, affirming stance. Analyses included linear regression and mixed models., Results: Formulation letters that paid attention to the development of the AN predicted greater treatment acceptability ratings (p = 0.002). More reflective and respectful letters predicted greater reductions in Eating Disorder Examination scores (p = 0.003)., Discussion: Results highlight the potential significance of a particular style of written formulation as part of treatment for AN. Future research should examine applicability to other psychiatric disorders. © 2016 Wiley Periodicals, Inc.(Int J Eat Disord 2016; 49:874-882)., (© 2016 Wiley Periodicals, Inc.) more...

Objective: This study reports follow-up data from a multicenter randomized controlled trial (n = 142) comparing the Maudsley Model of Anorexia Nervosa Treatment for Adults (MANTRA) with Specialist Supportive Clinical Management (SSCM) in outpatients with broadly defined anorexia nervosa (AN). At 12 months postrandomization, all patients had statistically significant improvements in body mass index (BMI), eating disorder (ED) symptomatology and other outcomes with no differences between groups. MANTRA was more acceptable to patients. The present study assessed whether gains were maintained at 24 months postrandomization., Methods: Follow-up data at 24 months were obtained from 73.2% of participants. Outcome measures included BMI, ED symptomatology, distress, impairment, and additional service utilization during the study period. Outcomes were analyzed using linear mixed models., Results: There were few differences between groups. In both treatment groups, improvements in BMI, ED symptomatology, distress levels, and clinical impairment were maintained or increased further. Estimated mean BMI change from baseline to 24 months was 2.16 kg/m(2) for SSCM and 2.25 kg/m(2) for MANTRA (effect sizes of 1.75 and 1.83, respectively). Most participants (83%) did not require any additional intensive treatments (e.g., hospitalization). Two SSCM patients became overweight through binge-eating., Discussion: Both treatments have value as outpatient interventions for patients with AN. © 2016 Crown copyright.

- Abstract
Background: This study is part of a series of process evaluations within the MOSAIC Trial (Maudsley Outpatient Study of Treatments for Anorexia Nervosa and Related Conditions). This randomised controlled trial (RCT) compared two psychological treatments, the Maudsley Model for Treatment of Adults with Anorexia Nervosa (MANTRA) and Specialist Supportive Clinical Management (SSCM) for adult outpatients with Anorexia Nervosa. The present process study integrates quantitative (treatment acceptability and credibility) and qualitative (written) feedback to evaluate patients' treatment experiences., Method: All 142 MOSAIC participants were asked to (a) rate treatment acceptability and credibility on visual analogue scales (VAS) at six and 12 months post-randomisation, and (b) provide written feedback regarding their views on their treatment at 12 months. Transcripts were first analysed thematically and then rated according to the global valence of feedback (positive, mixed/negative)., Results: 114/142 (80.3 %) MOSAIC participants provided VAS data and 82 (57.7 %) provided written feedback. At 12 months, MANTRA patients gave significantly higher acceptability and credibility ratings compared to SSCM patients. A significantly higher proportion of MANTRA patients provided written feedback. MANTRA patients also tended to write in more detail and to give globally more positive feedback when compared to individuals receiving SSCM. Qualitative themes suggest that patients experienced the two treatments differently in terms of characteristics and outcomes., Conclusions: This study highlights the benefits of incorporating qualitative and quantitative data into RCT process evaluations. MANTRA patients were more willing to express their views on treatment and generally felt more positively about this than those receiving SSCM. more...

- Abstract
This study investigated whether dopaminergic systems are involved in the motivation to engage in behaviours associated with anorexia nervosa (AN), specifically, the drive to exercise. Women recovered from AN (AN REC, n = 17) and healthy controls (HC, n = 15) were recruited. The acute phenylalanine/tyrosine depletion (APTD) method was used to transiently decrease dopamine synthesis and transmission. The effect of dopamine precursor depletion on drive to exercise was measured using a progressive ratio (PR) exercise breakpoint task. Both groups worked for the opportunity to exercise, and, at baseline, PR breakpoint scores were higher in AN REC than HC. Compared to values on the experimental control session, APTD did not decrease PR breakpoint scores in AN REC, but significantly decreased scores in HC. These data show that women recovered from AN are more motivated to exercise than HC, although in both groups, activity is more reinforcing than inactivity. Importantly, decreasing dopamine does not reduce the motivation to exercise in people recovered from AN, but in contrast, does so in HC. It is proposed that in AN, drive to exercise develops into a behaviour that is largely independent of dopamine mediated reward processes and becomes dependent on cortico-striatal neurocircuitry that regulates automated, habit- or compulsive-like behaviours. These data strengthen the case for the involvement of reward, learning, habit, and dopaminergic systems in the aetiology of AN. more...

- Abstract
Objective: Anorexia nervosa (AN) in adults has poor outcomes, and treatment evidence is limited. This study evaluated the efficacy and acceptability of a novel, targeted psychological therapy for AN (Maudsley Model of Anorexia Nervosa Treatment for Adults; MANTRA) compared with Specialist Supportive Clinical Management (SSCM)., Method: One hundred forty-two outpatients with broadly defined AN (body mass index [BMI] ≤ 18.5 kg/m²) were randomly allocated to receive 20 to 30 weekly sessions (depending on clinical severity) plus add-ons (4 follow-up sessions, optional sessions with dietician and with carers) of MANTRA (n = 72) or SSCM (n = 70). Assessments were administered blind to treatment condition at baseline, 6 months, and 12 months after randomization. The primary outcome was BMI at 12 months. Secondary outcomes included eating disorders symptomatology, other psychopathology, neuro-cognitive and social cognition, and acceptability. Additional service utilization was also assessed. Outcomes were analyzed using linear mixed models., Results: Both treatments resulted in significant improvements in BMI and reductions in eating disorders symptomatology, distress levels, and clinical impairment over time, with no statistically significant difference between groups at either 6 or 12 months. Improvements in neuro-cognitive and social-cognitive measures over time were less consistent. One SSCM patient died. Compared with SSCM, MANTRA patients rated their treatment as significantly more acceptable and credible at 12 months. There was no significant difference between groups in additional service consumption., Conclusions: Both treatments appear to have value as first-line outpatient interventions for patients with broadly defined AN. Longer term outcomes remain to be evaluated., ((c) 2015 APA, all rights reserved).) more...

- Abstract
Objective: This study aimed to explore the neuro- and social-cognitive profile of a consecutive series of adult outpatients with anorexia nervosa (AN) when compared with widely available age and gender matched historical control data. The relationship between performance profiles, clinical characteristics, service utilization, and treatment adherence was also investigated., Method: Consecutively recruited outpatients with a broad diagnosis of AN (restricting subtype AN-R: n = 44, binge-purge subtype AN-BP: n = 33 or Eating Disorder Not Otherwise Specified-AN subtype EDNOS-AN: n = 23) completed a comprehensive set of neurocognitive (set-shifting, central coherence) and social-cognitive measures (Emotional Theory of Mind). Data were subjected to hierarchical cluster analysis and a discriminant function analysis., Results: Three separate, meaningful clusters emerged. Cluster 1 (n = 45) showed overall average to high average neuro- and social- cognitive performance, Cluster 2 (n = 38) showed mixed performance characterized by distinct strengths and weaknesses, and Cluster 3 (n = 17) showed poor overall performance (Autism Spectrum disorder (ASD) like cluster). The three clusters did not differ in terms of eating disorder symptoms, comorbid features or service utilization and treatment adherence. A discriminant function analysis confirmed that the clusters were best characterized by performance in perseveration and set-shifting measures., Discussion: The findings suggest that considerable neuro- and social-cognitive heterogeneity exists in patients with AN, with a subset showing ASD-like features. The value of this method of profiling in predicting longer term patient outcomes and in guiding development of etiologically targeted treatments remains to be seen., (© 2014 Wiley Periodicals, Inc.) more...

- Abstract
Objective: This study is the second part of a process evaluation, embedded in the MOSAIC study, a large randomised controlled trial comparing two different psychological therapies, the Maudsley Model for Treatment of Adults with Anorexia Nervosa (MANTRA) and Specialist Supportive Clinical Management (SSCM). The study adopted a qualitative approach to examine patient experiences of the two treatments., Method: Seventeen semi-structured interviews were conducted with Anorexia Nervosa and Eating Disorder Not Otherwise Specified-Anorexia Nervosa type patients, and transcripts were analysed thematically., Results: Patient responses yielded five main themes: positive and helpful aspects, beneficial outcomes, less helpful aspects, possible improvements to the treatments, and the therapeutic and external environment. The findings show clear differences and some overlaps between patients' views on MANTRA and SSCM., Discussion: Both therapies were experienced by patients as credible and largely helpful, albeit in different ways. These results are in agreement with those of therapists' views on these treatments., (Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.) more...

- Abstract
Objectives: Forming part of a process evaluation of a large randomised controlled trial (the Maudsley Outpatient Study of Treatments for Anorexia Nervosa and Related conditions, MOSAIC) comparing two outpatient therapies for Anorexia Nervosa (AN), the Maudsley Model for Treatment of Adults with Anorexia Nervosa (MANTRA) and Specialist Supportive Clinical Management (SSCM), this study adopted a qualitative approach to examine therapist experiences of treatment delivery., Method: Twenty MOSAIC therapists completed semi-structured interviews. Interviews were recorded, transcribed and analysed thematically., Results: Themes of positive aspects, challenges and therapeutic fit emerged. MANTRA was seen as structured and flexible but could feel demanding on therapist time and skill. The slow pace and narrower focus of SSCM gave patients space to talk, but the lack of psychological tools and nutritional emphasis could create frustration. Views on the therapeutic relationship and patient-therapy fit differed across treatments., Discussion: Findings provide testable hypotheses about what works for whom, ideas for therapist training, treatment development and delivery., (Copyright © 2014 John Wiley & Sons, Ltd and Eating Disorders Association.) more...

- Abstract
Objective: Attentional bias (AB) modification treatment targeting general or social anxiety has been recently highlighted as a potential novel approach for the treatment of anorexia nervosa (AN). The purpose of this study was to examine threat-related AB in patients with ANand healthy control participants (HC) and the relationship between AB and eating disorder and other psychopathology., Method: Forty-nine female outpatients with AN or Eating Disorder Not Otherwise Specified, Anorexia Type (EDNOS-AN), and 44 female HC completed a dot-probe task with threat words and a range of self-report measures assessing eating disorder symptoms and other psychopathology., Results: There was no evidence for a differential threat-related AB in AN patients despite elevated anxiety in this group. The AB-index, a parameter of the magnitude of attention allocation when two competing stimuli are presented, did not correlate with any of the self-report measures. However, patients with AN responded significantly more slowly to the probe as compared to controls, regardless of the valence or position of the stimuli., Discussion: The results suggest that the AB in AN patients may be specific to eating disorder-relevant anxieties., (Copyright © 2013 Wiley Periodicals, Inc.) more...

- Abstract
Objective: Psychological treatments for eating disorders (ED) rely on mastery of effortful attentional control to divert attention from anxiety provoking thoughts. This paper assesses the potential suitability of attentional bias modification treatment (ABMT) for EDs as a way to target early automatic attentional processes and implicitly retune threat perception that happens outside of conscious control., Method: We review data on anxiety in EDs, the neurobiological and behavioural relationship between anxiety disorders and EDs, attentional biases (AB) in EDs and the use of ABMT., Results: Co-morbidities between EDs and anxiety disorders are common and negatively affect illness outcome. EDs and anxiety disorders share many underlying elements, including AB towards threatening and disorder-relevant stimuli. AB has been modified across a range of anxiety disorders using ABMT. It is possible to modify AB in EDs., Conclusion: There is evidence to suggest that ABMT has potential as a targeted, rapid and convenient treatment option for EDs., (Copyright © 2013 John Wiley & Sons, Ltd and Eating Disorders Association.) more...

- Abstract
Background: Anorexia nervosa (AN) is a biologically based serious mental disorder with high levels of mortality and disability, physical and psychological morbidity and impaired quality of life. AN is one of the leading causes of disease burden in terms of years of life lost through death or disability in young women. Psychotherapeutic interventions are the treatment of choice for AN, but the results of psychotherapy depend critically on the stage of the illness. The treatment response in adults with a chronic form of the illness is poor and drop-out from treatment is high. Despite the seriousness of the disorder the evidence-base for psychological treatment of adults with AN is extremely limited and there is no leading treatment. There is therefore an urgent need to develop more effective treatments for adults with AN. The aim of the Maudsley Outpatient Study of Treatments for Anorexia Nervosa and Related Conditions (MOSAIC) is to evaluate the efficacy and cost effectiveness of two outpatient treatments for adults with AN, Specialist Supportive Clinical Management (SSCM) and the Maudsley Model of Treatment for Adults with Anorexia Nervosa (MANTRA)., Methods/design: 138 patients meeting the inclusion criteria are randomly assigned to one of the two treatment groups (MANTRA or SSCM). All participants receive 20 once-weekly individual therapy sessions (with 10 extra weekly sessions for those who are severely ill) and four follow-up sessions with monthly spacing thereafter. There is also optional access to a dietician and extra sessions involving a family member or a close other. Body weight, eating disorder- related symptoms, neurocognitive and psychosocial measures, and service use data are measured during the course of treatment and across a one year follow up period. The primary outcome measure is body mass index (BMI) taken at twelve months after randomization., Discussion: This multi-center study provides a large sample size, broad inclusion criteria and a follow-up period. However, the study has to contend with difficulties directly related to running a large multi-center randomized controlled trial and the psychopathology of AN. These issues are discussed. more...

- Abstract
We report the case of a 55-year-old man who presented with a left hemisphere stroke. The initial computed tomography scan demonstrated a cerebral infarct in association with a left middle cerebral artery occlusion. Carotid duplex ultrasound imaging revealed a surgical grade stenosis of the proximal left internal carotid artery; however, in view of the uncertain benefits of internal carotid endarterectomy in the face of ipsilateral middle cerebral artery occlusion, surgery was deferred. Subsequent surveillance by transcranial Doppler imaging and repeat computed tomography demonstrated spontaneous recanalization. The patient proceeded to carotid endarterectomy with no complications. more...
