Gamma knife capsulotomy for intractable OCD: Neuroimage analysis of lesion size, location, and clinical response. Transl Psychiatry 2023; 13:134. [PMID: 37185805 PMCID: PMC10130137 DOI: 10.1038/s41398-023-02425-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2022] [Revised: 02/27/2023] [Accepted: 03/31/2023] [Indexed: 05/17/2023] Open
Abstract
Obsessive-compulsive disorder (OCD) affects 2-3% of the population. One-third of patients are poorly responsive to conventional therapies, and for a subgroup, gamma knife capsulotomy (GKC) is an option. We examined lesion characteristics in patients previously treated with GKC through well-established programs in Providence, RI (Butler Hospital/Rhode Island Hospital/Alpert Medical School of Brown University) and São Paulo, Brazil (University of São Paolo). Lesions were traced on T1 images from 26 patients who had received GKC targeting the ventral half of the anterior limb of the internal capsule (ALIC), and the masks were transformed into MNI space. Voxel-wise lesion-symptom mapping was performed to assess the influence of lesion location on Y-BOCS ratings. General linear models were built to compare the relationship between lesion size/location along different axes of the ALIC and above or below-average change in Y-BOCS ratings. Sixty-nine percent of this sample were full responders (≥35% improvement in OCD). Lesion occurrence anywhere within the targeted region was associated with clinical improvement, but modeling results demonstrated that lesions occurring posteriorly (closer to the anterior commissure) and dorsally (closer to the mid-ALIC) were associated with the greatest Y-BOCS reduction. No association was found between Y-BOCS reduction and overall lesion volume. GKC remains an effective treatment for refractory OCD. Our data suggest that continuing to target the bottom half of the ALIC in the coronal plane is likely to provide the dorsal-ventral height required to achieve optimal outcomes, as it will cover the white matter pathways relevant to change. Further analysis of individual variability will be essential for improving targeting and clinical outcomes, and potentially further reducing the lesion size necessary for beneficial outcomes.

Abstract
A prescriber might ask if a new medication is a good option for use in the patients he or she sees in clinic, with their particular blends of demographic and comorbid clinical characteristics. Is this medicine more effective, safe, tolerable, or affordable than the options used in the past? A payer may ask if the new medication offers a more effective, cost-efficient, or convenient alternative to those treatments already being covered. These are the types of questions that are often difficult to answer on the basis of the clinical trials used to support a medication's initial approval, which are generally designed to evaluate a medication's efficacy, safety, and tolerability in narrowly defined patient populations. Consequently, in order to answer the questions most relevant to key stakeholders (i.e., regulators, patients, and clinicians), it is important to continue to examine a medication's impact and characteristics after it has received regulatory approval. Such studies vary in their purpose, scope, and methodology. In this chapter, we review the types of questions most likely to be investigated after regulatory approval, the methods generally used to investigate them, and the characteristics typically considered when prioritizing the allocation of resources.

Abstract
IntroductionHospital discharge is a significant transitional phase with varying levels of needs and risks to be managed as lapses in communication commonly happen between secondary/tertiary and primary care.ObjectivesOur aim was to look at inclusion of delirium diagnosis in discharge summaries based on standards set by: 1. Health Information and Quality Authority (HIQA) National Standard for Patient Discharge Summary Information 2. NICE Guidelines on Delirium: prevention, diagnosis and management (CG 103)MethodsAll inpatients referred to Liaison Psychiatry from 9thJuly 2019 till 5th January 2020 were included, n = 729. Compared discharge summaries diagnoses to the internal Liaison Psychiatry ICD 10 consensus diagnosis and also HIPE coded diagnosis specifically for delirium.ResultsDelirium diagnoses and inclusion of delirium-specific information on discharge summarynProportion (n=112*) (%)Q1 Any F05 diagnosis coded by Liaison Psychiatry117100Q2 F10.4 diagnosis coded by Liaison Psychiatry00Q3 F1x.4 diagnosis coded by Liaison Psychiatry00Q4 Any F05, F10.4 and F1x.4 diagnosis coded in discharge summary on patient centre2320.5Q5 Was the word delirium or its synonym such as acute confusional state mentioned in the body of the discharge summary?6255.4HIPE Code Diagnosis6658.9ConclusionsHospital discharge summaries are essentially the main communication link between hospitalists and general practitioners to ensure continuity and future care of patients. Delirium diagnosis is not always recorded in discharge summaries. This is a risk to be managed. Education is vital to ensure awareness, prevention, early recognition and to ensure recording of diagnosis of delirium.

The general populations' understanding of first trimester miscarriage: a cross sectional survey. Eur J Obstet Gynecol Reprod Biol 2020; 254:200-205. [PMID: 33010694 DOI: 10.1016/j.ejogrb.2020.08.042] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2020] [Revised: 08/11/2020] [Accepted: 08/21/2020] [Indexed: 11/29/2022]
Abstract
OBJECTIVES Miscarriage is a common, yet for many, devastating adverse pregnancy outcome. However, despite this the level of public knowledge on the topic is sub-optimal. We aimed to examine the general public's knowledge of miscarriage as well as their health information seeking behaviours associated with this topic. STUDY DESIGN We commissioned a national cross-sectional telephone survey of adults in the Republic of Ireland. 967 members of the general public consented to participate to this anonymised telephone survey. Sampling procedures ensured proportionality as per national standards. We examined respondents' definitions of miscarriage, its incidence and clinical findings, as well as the information seeking behaviours of the general population surrounding miscarriage. RESULTS 699 (72%) of respondents provided an estimate of miscarriage frequency, with 28% of respondents correctly estimating that miscarriage occurs in 21-30% of pregnancies, with 61% under-estimating the incidence. Men were three times more likely than women to under-estimate (aOR3.5; 95% CI 2.4-4.9), as were those without children (aOR 1.7; 95% CI 1.2-2.6), or those living in urban areas (aOR 1.6; 95%CI 1.0-2.4. One third of respondents (33%) believed that the risk of miscarriage was higher following only one miscarriage. While 83% of respondents knew someone who had experienced a miscarriage, just over one third had discussed the topic of miscarriage with a family member/friend. CONCLUSIONS The general populations' knowledge of miscarriage, its incidence and associated factors is concerning, as are their health information seeking behaviours. Improving the level of knowledge of the general public could be achieved by adopting the topic into existing public health and education strategies. This will allow those experiencing miscarriage to frame their experience and expectations.

Abstract
Abstract
ERBB2, the gene encoding HER2, is mutated in 2-4% of breast cancers. The HER2 tyrosine kinase inhibitor neratinib has shown clinical activity against breast cancers harboring HER2 activating mutations, suggesting these tumors depend on HER2 signaling. Co-occurring HER2 and HER3 (ERBB3) mutations have been reported in patients who respond to neratinib (Hanker et al., Cancer Discov. 2017) suggesting the possibility of cooperativity of both oncogenes. Co-expression of the mutant intracellular domains of HER2 and HER3 in HEK293 cells enhanced phosphorylation of HER3 and ERK compared to expression of either mutant alone, which was blocked by 100 nM neratinib. Interrogation of TCGA, METABRIC, Project GENIE, and Foundation Medicine datasets revealed that gain-of-function mutations in ERBB2 and ERBB3 co-occur with a statistically significant frequency. For example, in GENIE, ERBB2 mutations co-occur with mutations in ERBB3 (8.3% of ERBB2-mutant vs 2.3% of ERBB2 WT; q=1.37x10-10).
We hypothesized that co-occurring mutations in HER2 and HER3 cooperate to enhance HER2 signaling and dependence and breast cancer progression.
Thirty-four unique breast cancers were found to harbor co-occurring mutations in HER2 and HER3, the most common of which were ERBB2L755S/ERBB3E928G (n=10), ERBB2V777L/ERBB3E928G(n=6), and ERBB2L869R/Q/ERBB3E928G (n=4). Using co-immunoprecipitation assays with HER2 and HER3 antibodies in transfected HEK293 cells, we found that co-expression of HER3E928G with wild type (WT) HER2, or co-expression of HER2L755S or HER2L869R with HER3WT, slightly increased HER2-HER3 dimerization. However, binding was strongest between double mutants. This was accompanied by the highest levels of Y1289 p-HER3 in cells expressing both HER3E928G and each HER2L755S, HER2V777L, or HER2L869R compared to cells expressing each HER2 or HER3 mutant with a respective WT heterodimer partner. Structural modeling of the HER2L869R/HER3E928G double-mutant predicted that the HER3 mutation, located at the dimer interface, may enhance heterodimerization of the kinase domains through decreased bulk and electrostatic repulsion. We also noted that the HER2L755S mutation is predicted to be in close proximity to HER3E928G (<4 Å) and may impact binding affinity. Investigation of the structural basis for the enhanced binding of other double mutants is in progress.
MCF7 “knock-in” cells incorporating HER2L755S, HER2V777L, or HER2L869R (or HER2WT) were stably transduced with HER3E928G or HER3WT. Co-expression of double mutants strongly enhanced estrogen-independent growth in 3D Matrigel over cells expressing either mutant alone. We are currently testing inhibitors of HER2/HER3 signaling, including neratinib ± trastuzumab, trastuzumab + pertuzumab, and the ERBB1-3 antibody mixture Sym013, to determine therapeutic strategies to block the cooperative growth induced by co-occurring HER2 and HER2 mutations.
Conclusions: Co-expression of mutant HER2 and mutant HER3 promotes HER2/HER binding, HER3 phosphorylation, and breast tumor cell proliferation. We aim to identify therapeutic vulnerabilities for patients with co-occurring HER2 and HER3 mutations.

Abstract
Thermal dose and absorbed radiation dose have historically been difficult to compare because different biological mechanisms are at work. Thermal dose denatures proteins and the radiation dose causes DNA damage in order to achieve ablation. The purpose of this paper is to use the proportion of cell survival as a potential common unit by which to measure the biological effect of each procedure. Survival curves for both thermal and radiation doses have been extracted from previously published data for three different cell types. Fits of these curves were used to convert both thermal and radiation dose into the same quantified biological effect: fraction of surviving cells. They have also been used to generate and compare survival profiles from the only indication for which clinical data are available for both focused ultrasound (FUS) thermal ablation and radiation ablation: essential tremor thalamotomy. All cell types could be fitted with coefficients of determination greater than 0.992. As an illustration, survival profiles of clinical thalamotomies performed by radiosurgery and FUS are plotted on a same graph for the same metric: fraction of surviving cells. FUS and Gamma Knife have the potential to be used in combination to deliver a more effective treatment (for example, FUS may be used to debulk the main tumour mass, and radiation to treat the surrounding tumour bed). In this case, a model which compares thermal and radiation treatments is valuable in order to adjust the dose between the two.

Abstract
OBJECTIVES Saxagliptin and sitagliptin are two commonly used dipeptidyl peptidase-4 (DPP-4) inhibitors. Little is known about their comparative effectiveness in the real world, particularly their impact on cost and resources use. The objective of this study was to analyze charges and resource use associated with saxagliptin and sitagliptin to understand the impact of these DPP-4 inhibitor treatment options in a real-world setting. METHODS This was a retrospective, new-user study approved by the Institutional Review Board at the University of Toledo. Data were collected from a US insurance claims dataset (OptumInsight) for patients newly initiating treatment with saxagliptin or sitagliptin between January 1, 2010 and December 31, 2011. ICD-9 code 250 was used to identify patients with T2D. Overall and diabetes-related medical and pharmacy charges were observed. Inpatient hospitalizations were also compared. Propensity score matching was used to balance the cohorts of patients prescribed saxagliptin and sitagliptin. Appropriate univariate statistical tests were applied to the propensity-matched sample to examine differences in resource utilization outcomes. Statistical significance was evaluated at P < 0.05. RESULT After the propensity score matching, each cohort included 7711 patients. Saxagliptin treatment was associated with lower overall charges ($13,292 vs $14,032; P = 0.0023) and overall medical charges ($9,540 vs $10,296; P = 0.0024) during the 6-month follow-up period compared with sitagliptin treatment. No significant differences were observed in the overall pharmacy charges ($3,751 vs $3,753; P = 0.6937) and the diabetes-related charges ($5,141 vs $5,232; P = 0.2957). All-cause and diabetes-related inpatient hospitalization rates were significantly lower with saxagliptin treatment (p = 0.0001 and p = 0.0019, respectively). All-caused inpatient charges were also significantly lower with saxagliptin ($2,917.26 vs $3445.89; P < 0.0001). CONCLUSION Compared with patients initiating sitagliptin treatment, patients initiating saxagliptin treatment reported lower overall and medical charges and lower overall and diabetes-related hospitalization rates. These findings may aid payers in managing patients with T2D.

Abstract
Disorder-specific (DS-CBT) and transdiagnostic (TD-CBT) cognitive behaviour therapy have both been used to treat social anxiety disorder (SAD). This study compared internet-delivered DS-CBT and TD-CBT for SAD across clinician-guided (CG-CBT) and self-guided (SG-CBT) formats. Participants with SAD (n=233) were randomly allocated to receive internet-delivered TD-CBT or DS-CBT and CG-CBT or SG-CBT. Large reductions in symptoms of SAD (Cohen's d≥1.01; avg. reduction≥30%) and moderate-to-large reductions in symptoms of comorbid depression (Cohen's d≥1.25; avg. reduction≥39%), generalised anxiety disorder (Cohen's d≥0.86; avg. reduction≥36%) and panic disorder (Cohen's d≥0.53; avg. reduction≥25%) were found immediately post-treatment and were maintained or further improved to 24-month follow-up. No marked differences were observed between TD-CBT and DS-CBT or CG-CBT and SG-CBT highlighting the potential of each for the treatment of SAD and comorbid disorders.

Abstract
Transdiagnostic cognitive behaviour therapy (TD-CBT) aims to target the symptoms of multiple disorders whereas disorder-specific CBT (DS-CBT) targets the symptoms of principal disorders. This study compared the relative benefits of internet-delivered TD-CBT and DS-CBT when provided in clinician-guided (CG-CBT) and self-guided (SG-CBT) formats for people with a principal diagnosis of Panic Disorder (PD). Participants (n=145) were randomly allocated to receive TD-CBT or DS-CBT and CG-CBT or SG-CBT. Large reductions in symptoms of PD (Cohen's d ≥ 0.71; avg. reduction ≥ 36%) and moderate-to-large reductions in symptoms of comorbid depression (Cohen's d ≥ 0.71; avg. reduction ≥ 33%), generalised anxiety disorder (Cohen's d ≥ 0.91; avg. reduction ≥ 34%) and social anxiety disorder (Cohen's d ≥ 0.50; avg. reduction ≥ 15%) were found over the 24-month follow-up period. Highlighting their efficacy and acceptability, no marked and consistent differences were observed between TD-CBT and DS-CBT or CG-CBT and DS-CBT.

Abstract
Disorder-specific cognitive behavior therapy (DS-CBT) is effective at treating major depressive disorder (MDD) while transdiagnostic CBT (TD-CBT) addresses both principal and comorbid disorders by targeting underlying and common symptoms. The relative benefits of these two models of therapy have not been determined. Participants with MDD (n=290) were randomly allocated to receive an internet delivered TD-CBT or DS-CBT intervention delivered in either clinician-guided (CG-CBT) or self-guided (SG-CBT) formats. Large reductions in symptoms of MDD (Cohen's d≥1.44; avg. reduction≥45%) and moderate-to-large reductions in symptoms of comorbid generalised anxiety disorder (Cohen's d≥1.08; avg. reduction≥43%), social anxiety disorder (Cohen's d≥0.65; avg. reduction≥29%) and panic disorder (Cohen's d≥0.45; avg. reduction≥31%) were found. No marked or consistent differences were observed across the four conditions, highlighting the efficacy of different forms of CBT at treating MDD and comorbid disorders.

Abstract
Macrovascular and microvascular complications that accompany Type 2 diabetes mellitus (T2DM) add to the burden among patients. The purpose of this systematic review is to conduct a comprehensive search of the medical literature investigating the prevalence of cardiovascular (CV) complications and assess their impact on healthcare costs, quality of life and mortality among patients with T2DM in the context of microvascular complications. A total of 76 studies and reports were used in this systematic review. Hypertension was the most prevalent complication among patients with T2DM. The additional cost burden due to CV complications was higher than any other complication except end-stage renal disease. Quality of life was much lower among patients with CV complications and T2DM, and mortality was higher than either illness alone.

Abstract
BACKGROUND The efficacy of adjunctive aripiprazole in patients with major depressive disorder (MDD) with no improvement after 8 weeks of prior antidepressant monotherapy has not been evaluated. METHODS A post hoc analysis of three similarly designed, randomised, double-blind, placebo-controlled, phase III studies was conducted investigating the efficacy and safety of aripiprazole adjunctive to standard antidepressant treatment (ADT) in MDD patients with a prior inadequate response to one to three ADTs. Minimal improvement to antidepressant monotherapy was defined as a Clinical Global Impressions - Improvement (CGI-I) score of 3 and non-improvement as a CGI-I of 4 at weeks 6 and 8 of antidepressant monotherapy. RESULTS The end-point response rate for ADT minimal improvers receiving adjunctive aripiprazole was 38.8% vs. 26.6% for adjunctive placebo (p < 0.05; number needed to treat [NNT] = 9 [95% confidence interval: 4.8-27.7]), and for ADT non-improvers receiving adjunctive aripiprazole was 24.0% vs. 10.3% for adjunctive placebo (p < 0.05; NNT = 8 [95% confidence interval: 4.4-21.5]). ADT minimal improvers and non-improvers demonstrated significant improvements in response vs. ADT alone as early as after 1 and 2 weeks of adjunctive treatment, respectively. The end-point remission rate for ADT minimal improvers receiving adjunctive aripiprazole was 34.2% vs. 21.0% for adjunctive placebo (p < 0.05; NNT = 8), and for ADT non-improvers receiving adjunctive aripiprazole was 16.0% vs. 5.9% for adjunctive placebo (p < 0.05; NNT = 10). The most common adverse events for ADT minimal improvers and non-improvers receiving adjunctive aripiprazole were akathisia, restlessness and insomnia. CONCLUSION Patients with minimal or no improvement after 8 weeks of antidepressant monotherapy significantly benefited from adjunctive aripiprazole treatment, supporting the efficacy of this treatment for MDD patients with all levels of response to ADT.

Abstract
OBJECTIVE To assess the current use of glucocorticoids (GCs) in Duchenne muscular dystrophy in the UK, and compare the benefits and the adverse events of daily versus intermittent prednisolone regimens. DESIGN A prospective longitudinal observational study across 17 neuromuscular centres in the UK of 360 boys aged 3-15 years with confirmed Duchenne muscular dystrophy who were treated with daily or intermittent (10 days on/10 days off) prednisolone for a mean duration of treatment of 4 years. RESULTS The median loss of ambulation was 12 years in intermittent and 14.5 years in daily treatment; the HR for intermittent treatment was 1.57 (95% CI 0.87 to 2.82). A fitted multilevel model comparing the intermittent and daily regiments for the NorthStar Ambulatory Assessment demonstrated a divergence after 7 years of age, with boys on an intermittent regimen declining faster (p<0.001). Moderate to severe side effects were more commonly reported and observed in the daily regimen, including Cushingoid features, adverse behavioural events and hypertension. Body mass index mean z score was higher in the daily regimen (1.99, 95% CI 1.79 to 2.19) than in the intermittent regimen (1.51, 95% CI 1.27 to 1.75). Height restriction was more severe in the daily regimen (mean z score -1.77, 95% CI -1.79 to -2.19) than in the intermittent regimen (mean z score -0.70, 95% CI -0.90 to -0.49). CONCLUSIONS Our study provides a framework for providing information to patients with Duchenne muscular dystrophy and their families when introducing GC therapy. The study also highlights the importance of collecting longitudinal natural history data on patients treated according to standardised protocols, and clearly identifies the benefits and the side-effect profile of two treatment regimens, which will help with informed choices and implementation of targeted surveillance.

Abstract
AIM The aim of the study was to assess the early clinical experience with the Zilver Vena stent in treating patients with iliofemoral venous obstruction at a tertiary referral hospital. METHODS Demographic, procedural, and follow-up data of 20 patients (12 women; mean age of 59 ± 17 years) treated for iliofemoral vein obstruction between January 2011 and December 2012 were retrospectively reviewed. Most patients presented with acute obstruction (N.=14; 70%), and 10 patients (50%) had an active malignancy. Patency was established venographically at procedure end, and was evaluated with Duplex ultrasound in follow-up. RESULTS Venous obstructions were attributed primarily to extrinsic compression from a malignant or other mass in the pelvis (N.=9) and May-Thurner (N.=5). Flow was re-established through the obstructed venous segment in all patients at procedure end. In follow-up, three patients experienced early stent thrombosis (<30 days); the clinical patency rate was 85% (17/20 patients). Clinical improvement was demonstrated by decreased leg swelling in the remaining 17 patients. CONCLUSION The Zilver Vena stent performed favorably in this challenging patient population; these results need to be confirmed in multicenter studies.

Abstract
Central Core Disease (CCD) and Multi-minicore Disease (MmD) (the "core myopathies") have been mainly associated with mutations in the skeletal muscle ryanodine receptor (RYR1) and the selenoprotein N (SEPN1) gene. A proportion of cases remain unresolved. Mutations in MYH7 encoding the beta myosin heavy chain protein have been implicated in cardiac and, less frequently, skeletal muscle disorders. Here we report four patients from two families with a histopathological diagnosis of MmD, presenting in childhood with slowly progressive muscle weakness, more proximal in Family 1 and more distal in Family 2, and variable degrees of cardiorespiratory impairment evolving later in life. There was also a strong family history of sudden death in the first family. Muscle biopsies obtained in early childhood showed multiple minicores as the most prominent feature. Sequencing of the MYH7 gene revealed heterozygous missense mutations, c.4399C>G; p.Leu1467Val (exon 32) in Family 1 and c.4763G>C; p.Arg1588Pro (exon 34) in Family 2. These findings suggest MYH7 mutations as another cause of a myopathy with multiple cores, in particular if associated with dominant inheritance and cardiac involvement. However, clinical features previously associated with this genetic background, namely a more distal distribution of weakness and an associated cardiomyopathy, may only evolve over time.

Abstract
A miscarriage can be very traumatic for a couple and their immediate family. The aim of this study was to assess, using the Perinatal Grief Scale (PGS), whether the type of early pregnancy loss influences the severity of grief and whether the presence of living children influences the severity of grief. Over a period of 6 months in 2008, seventy five patients were recruited for the study, of which 7 (9.3%) had molar pregnancies, 20 (26.7%) had ectopic pregnancies, 43 (573%) had a miscarriage and 5 (6.7%) had recurrent miscarriages. In this study there was no significant difference in severity of grief, between women that had a miscarriage and ectopic pregnancy (p = 0.14) or, between women that had a miscarriage and a molar pregnancy (p = 0.85). Women who had experienced a ectopic pregnancy did not have a higher grief intensity than the women that had a molar pregnancy (p = 0.75). However, for women with a child, the grief intensity significantly increases with the number of miscarriages (p = 0.015). Women with no children with an ectopic pregnancy grieve significantly more than those with a child (p = 0.019). An appointment for the 'Miscarriage Clinic' should be offered to all of these women but special attention should be paid to those in the categories most at risk

Abstract
PURPOSE To develop and evaluate a modified anthropomorphic head phantom for evaluation of stereotactic radiosurgery (SRS) dose planning and delivery. METHODS A phantom was constructed from a water equivalent, plastic, head-shaped shell. The original phantom design, with only a spherical target, was modified to include a nonspherical target (pituitary) and an adjacent organ at risk (OAR) (optic chiasm), within 2 mm, simulating the anatomy encountered when treating acromegaly. The target and OAR spatial proximity provided a more realistic treatment planning and dose delivery exercise. A separate dosimetry insert contained two TLD for absolute dosimetry and radiochromic film, in the sagittal and coronal planes, for relative dosimetry. The prescription was 25Gy to 90% of the GTV with >= 10% of the OAR volume receiving >= 8Gy. The modified phantom was used to test the rigor of the treatment planning process, dosimeter reproducibility, and measured dose delivery agreement with calculated doses using a Gamma Knife, CyberKnife, and linear accelerator based radiosurgery systems. RESULTS TLD results from multiple irradiations using either a CyberKnife or Gamma Knife agreed with the calculated target dose to within 4.7% with a maximum coefficient of variation of+/-2.0%. Gamma analysis in the coronal and sagittal film planes showed an average passing rate of 99.3% and 99.5% using +/-5%/3mm criteria, respectively. A treatment plan for linac delivery was developed meeting the prescription guidelines. Dosimeter reproducibility and dose delivery agreement for the linac is expected to have results similar to the results observed with the CyberKnife and Gamma Knife. CONCLUSIONS A modified anatomically realistic SRS phantom was developed that provided a realistic clinical planning and delivery challenge that can be used to credential institutions wanting to participate in NCI funded clinical trials.

Abstract
BACKGROUND Brain-imaging literature of irritable bowel syndrome (IBS) suggests an abnormal brain-gut communication. We analyzed the literature to evaluate and compare the aspects of brain activity in individuals with IBS and control subjects experiencing controlled rectal stimulation. METHODS PubMed was searched until September 2010. Data from 16 articles reporting brain activity during rectal balloon distensions in IBS compared to control groups was analyzed. Prevalence rates and pairwise activations were assessed using binomial distributions for 11 selected regions of interest. The data were aggregated to adjust for center effect. KEY RESULTS There was considerable variability in the literature regarding regions and their activity patterns in controls and individuals with IBS. There was no significant difference found in the thalamus, anterior cingulate cortex, posterior cingulate cortex, and prefrontal cortex, however, results show limited evidence of consensus for the anterior insula (AI) (P = 0.22). Pairwise activity results suggest that pairs involving the AI tend to have more consistent activity together than pairs which do not involve the AI (posterior insula and AI, P = 0.08; posterior cingulate cortex and AI, P = 0.16), however, no pairwise evaluation reached significance. CONCLUSIONS & INFERENCES Our pooled analysis demonstrates that the literature reports are quite heterogeneous but there is some evidence that there may be patterns of higher activity more common in individuals with IBS than in controls. A consensus, though, regarding study designs, analysis approach and reporting could create a clearer understanding of brain involvement in IBS pathophysiology.
