Abstract
AIM The standard approach for the surgical management of colorectal cancer (CRC) in the setting of ulcerative colitis (UC) involves total proctocolectomy (TPC). However, some patients also undergo a partial resection (PR). This may be an attractive option in older patients with a high risk for surgery. The aim of this study was to compare the risk of metachronous cancer after PR or TPC for CRC in the setting of UC. METHOD This was a retrospective cohort study conducted through the Nationwide Veterans Affairs Healthcare System (VA). Patients who had UC and underwent a PR or TPC for CRC were followed from the time of their surgery to their most recent clinical follow-up. The primary outcome was development of metachronous cancer in the PR group. Secondary outcomes included surgical and medical outcomes. RESULTS Fifty-nine patients were included: 24 (40.7%) underwent PR and 35 (59.3%) underwent TPC. The median age at cancer diagnosis was 73.0 and 61.7 years in PR and TPC groups, respectively (P < 0.0005). Amongst patients undergoing PR, 15 (60%) had no active UC at the time of surgery, whereas in patients undergoing TPC, at the time of surgery eight (23.5%) had no active UC (P = 0.005). No patient who underwent a partial colectomy developed a metachronous cancer in the retained colonic segment during the follow-up period (median 7 years). CONCLUSION Our study suggests that PR for CRC in the setting of UC may be a viable option in a selected cohort of patients, especially among the elderly.

Abstract
BACKGROUND AND PURPOSE Feasibility of brain atrophy measurement in patients with MS in clinical routine, without prior standardization of the MRI protocol, is unknown. Our aim was to investigate the feasibility of brain atrophy measurement in patients with MS in clinical routine. MATERIALS AND METHODS Multiple Sclerosis and Clinical Outcome and MR Imaging in the United States (MS-MRIUS) is a multicenter (33 sites), retrospective study that included patients with relapsing-remitting MS who began treatment with fingolimod. Brain MR imaging examinations previously acquired at the baseline and follow-up periods on 1.5T or 3T scanners with no prior standardization were used, to resemble a real-world situation. Brain atrophy outcomes included the percentage brain volume change measured by structural image evaluation with normalization of atrophy on 2D-T1-weighted imaging and 3D-T1WI and the percentage lateral ventricle volume change, measured by VIENA on 2D-T1WI and 3D-T1WI and NeuroSTREAM on T2-fluid-attenuated inversion recovery examinations. RESULTS A total of 590 patients, followed for 16 months, were included. There were 585 (99.2%) T2-FLAIR, 425 (72%) 2D-T1WI, and 166 (28.2%) 3D-T1WI longitudinal pairs of examinations available. Excluding MR imaging examinations with scanner changes, the analyses were available on 388 (65.8%) patients on T2-FLAIR for the percentage lateral ventricle volume change, 259 and 257 (43.9% and 43.6%, respectively) on 2D-T1WI for the percentage brain volume change and the percentage lateral ventricle volume change, and 110 (18.6%) on 3D-T1WI for the percentage brain volume change and percentage lateral ventricle volume change. The median annualized percentage brain volume change was -0.31% on 2D-T1WI and -0.38% on 3D-T1WI. The median annualized percentage lateral ventricle volume change was 0.95% on 2D-T1WI, 1.47% on 3D-T1WI, and 0.90% on T2-FLAIR. CONCLUSIONS Brain atrophy was more readily assessed by estimating the percentage lateral ventricle volume change on T2-FLAIR compared with the percentage brain volume change or percentage lateral ventricle volume change using 2D- or 3D-T1WI in this observational retrospective study. Although measurement of the percentage brain volume change on 3D-T1WI remains the criterion standard and should be encouraged in future prospective studies, T2-FLAIR-derived percentage lateral ventricle volume change may be a more feasible surrogate when historical or other practical constraints limit the availability of percentage brain volume change on 3D-T1WI.

Abstract
Despite efforts to control toxigenic Fusarium species, wilt and head-blight infections are destructive and economically damaging diseases that have global effects. The utilization of biological control agents in disease management programs has provided an effective, safe, and sustainable means to control Fusarium-induced plant diseases. Among the most widely used microbes for biocontrol agents are members of the genus Bacillus. These species influence plant and fungal pathogen interactions by a number of mechanisms such as competing for essential nutrients, antagonizing pathogens by producing fungitoxic metabolites, or inducing systemic resistance in plants. The multivariate interactions among plant-biocontrol agent-pathogen are the subject of this study, in which we survey the advances made regarding the research on the Bacillus-Fusarium interaction and focus on the principles and mechanisms of action among plant-growth promoting Bacillus species. In particular, we highlight their use in limiting and controlling Fusarium spread and infestations of economically important crops. This knowledge will be useful to define strategies for exploiting this group of beneficial bacteria for use as inoculants by themselves or in combination with other microbes for enhanced crop protection.

Abstract
Punica granatum L. (wild) belongs to family Punicaceae, a woody plant, predominantly found on calcareous and alkaline soils. The species is extensively utilized as food and firewood and for the extraction of various chemicals due to its therapeutic properties. To understand the ethno-botanical and ecological status of the species on a regional scale, a questionnaire survey was conducted in the Dir (L) area using close and open-ended questionnaires. Data collected from 124 respondents were analysed quantitatively using statistical analysis to calculate indices like Relative Frequency of Citation (RFC), Use value (UV) and multivariate analysis. GPS data used for the presence data of the plants were used to develop GIS thematic maps. Geo-referenced data on P. granatum was collected from the study area, using GPS. Results suggest that the plant is mostly used as a remedy for dry cough, as an astringent, people used powder form of fruit peelings. It was documented in the present investigation that P. granatum is mainly eradicated due to its extensive use as firewood. The study also evaluated on the major aspect of how the P. granatum can be conserved naturally. It was found out that the plant is conserved in areas inaccessible to humans. The status of the vegetation community around this plant was also explored, it is found out that specific shrub and tree communities were major flora growing in proximity to P. granatum. The finding of this survey has concluded that wild P. granatum is an endangered species due to its extensive and uncontrollable use for firewood, curing diseases and its economic potential. These findings could be exploited to take necessary steps for the conservation of this species.

Abstract
The high-risk surgical patient is a growing challenge to modern health care. This cohort, although comprising only 10-15% of surgical procedures, accounts for approximately 80% of postoperative deaths and suffers a high rate of postoperative morbidity. Developing robust systems to help identify and better manage this patient group should be a priority. Risk stratification has become a valuable clinical tool for shared decision-making and the development of individualized care plans. Methods for stratifying individual risk include assessment tools, measures of functional capacity and plasma biomarker assays. Routine evaluation of perioperative risk is central to the delivery of high quality, appropriate surgical care.

Abstract
BACKGROUND The risk of herpes zoster (HZ) is elevated in inflammatory bowel disease (IBD) patients treated with anti-TNF medications. While it is optimal to give herpes zoster vaccine prior to initiation of therapy clinical circumstances may not always allow this. AIM To determine the safety of giving herpes zoster vaccine while patients are on anti-TNF therapy. METHODS We conducted a retrospective cohort study involving IBD patients who were followed in the Veterans Affairs (VA) healthcare system between 2001 and 2016. Patients who received herpes zoster vaccine while on anti-TNF medication were identified through vaccination codes and confirmed through individual chart review. Our outcome of interest was development of HZ between 0 and 42 days after herpes zoster vaccine administration. RESULTS Fifty-six thousand four hundred and seventeen patients with IBD were followed in the VA healthcare system. A total of 59 individuals were on anti-TNF medication when they were given herpes zoster vaccine, and amongst them, 12 (20%) were also taking a thiopurine. Median age at the time of herpes zoster vaccine was 64.9 years and 95% of patients had a Charlson Comorbidity Index of ≥2. Median number of encounters within 42 days after receiving herpes zoster vaccine was two. No case of HZ was found within 0-42 days of HZV administration. CONCLUSION Our data suggest that co-administering the herpes zoster vaccine to patients who are taking anti-TNF medications is relatively safe. This study significantly expands the evidence supporting the use of herpes zoster vaccine in this population, having included an elderly group of patients with a high Charlson Comorbidity Index who are likely at a much higher risk of developing HZ.

Abstract
BACKGROUND The Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI) and Cutaneous Assessment Tool-Binary Method (CAT-BM) have been shown to be reliable and valid outcome measures to assess cutaneous disease in adult dermatomyositis (DM) and juvenile DM (JDM), respectively. OBJECTIVES This study compared the CDASI and CAT-BM for use by paediatric dermatologists, paediatric rheumatologists and paediatric neurologists in patients with JDM. METHODS Five paediatric dermatologists, five paediatric rheumatologists and five paediatric neurologists each evaluated 14 patients with JDM using the CDASI, CAT-BM, and skin Physician Global Assessment (PGA) scales. Inter-rater reliability, intra-rater reliability, construct validity and completion time were compared. RESULTS Inter-rater reliability for CDASI activity and damage scores was good to moderate for paediatric dermatologists and rheumatologists, but poor for paediatric neurologists. The inter-rater reliability for CAT-BM activity scores was moderate for paediatric dermatologists and rheumatologists, but poor for paediatric neurologists and poor across all specialties for damage scores. Intra-rater reliability for the CDASI and CAT-BM activity and damage scores was moderate to excellent for paediatric dermatologists, rheumatologists and neurologists. Strong associations were found between skin PGA activity and damage scores and CDASI or CAT-BM activity and damage scores, respectively (P < 0·002). The CDASI had a mean completion time of 5·4 min compared with that for the CAT-BM of 3·1 min. CONCLUSIONS Our data confirm the reliability of the CDASI activity and damage scores and the CAT-BM activity scores when used by paediatric dermatologists and rheumatologists in assessing JDM. Significant variation existed in the paediatric neurologists' scores.

Abstract
OBJECTIVE Chronic symptomatic sinus node dysfunction (SND), the most common bradyarrhythmia, can be effectively managed by permanent cardiac pacing. Yet the care pathway and barriers to adoption of pacing therapy are not well understood - particularly in low volume implanting countries. The IMPROVE Brady study is a quality improvement initiative being conducted at centers in South Asia, Latin America, and Russia. We assessed the rates of SND diagnosis and pacemaker treatment for SND in the South Asia cohort. METHODS The prospective study enrolled patients with heart rate of ≤50 beats per minute presenting with symptoms including syncope, dizziness, and/or dyspnea from ten centers in India and Bangladesh. Patients were followed to identify the proportion diagnosed with SND and subsequently treated with pacemaker therapy. RESULTS A total of 508 patients meeting criteria were enrolled and followed on average for 8.3±8.0months. Patients were on average 58 years of age, 77% were male, and 91% had completed at least primary education. An SND diagnosis was made in 368 (72%) of patients, with the majority (80%) of diagnoses occurring within 1 month of enrollment. Of the patients with an SND diagnosis, 63 (17%) were treated with a pacemaker. Reasons for not receiving treatment were: subject refusal or deferred decision (45%), unaffordability (34%), physician determined - not-indicated (20%), and other (1%). Older age, female gender, history of hypertension, lower resting heart rate, and syncopal or pre-syncopal symptoms were associated with a higher probability of implant. CONCLUSIONS In a care pathway assessment for the diagnosis and treatment of symptomatic SND in South Asia only 1 in 6 patients received pacemaker indicated therapy, largely due to patient refusal and physician decision. Phase II of the study will be aimed to improve this treatment rate.

Abstract
Renormalization group theory does not restrict the form of continuous variation of critical exponents which occurs in presence of a marginal operator. However, the continuous variation of critical exponents, observed in different contexts, usually follows a weak universality scenario where some of the exponents (e.g., β, γ, ν) vary keeping others (e.g., δ, η) fixed. Here we report ferromagnetic phase transition in (Sm1−yNdy)0.52Sr0.48MnO3 (0.5 ≤ y ≤ 1) single crystals where all three exponents β, γ, δ vary with Nd concentration y. Such a variation clearly violates both universality and weak universality hypothesis. We propose a new scaling theory that explains the present experimental results, reduces to the weak universality as a special case, and provides a generic route leading to continuous variation of critical exponents and multi-criticality.

Abstract
OBJECTIVE This study aimed to examine the association between baseline and changes in dietary quality assessed by the Alternative Healthy Eating Index-2010 (AHEI-2010) and abdominal aortic calcification (AAC) among community-dwelling older adults. DESIGN Population-based longitudinal study. SETTING A subset of the Melbourne Collaborative Cohort Study (MCCS). PARTICIPANTS 262 community-dwelling adults (60% female) aged 53 ± 5 years at baseline. MEASUREMENTS Dietary intake was assessed using validated Food Frequency Questionnaires at baseline (1990-1994) and follow-up (2010-2011). AAC was evaluated by radiography and dual-energy x-ray absorptiometry (DXA) at follow-up. RESULTS Higher baseline AHEI-2010 score was associated with lower AAC severity by radiography [OR (95% CI) for Tertile 3 VS Tertile 1: 0.53 (0.29-0.99)] after adjustment for gender, age, physical activity, smoking, BMI, systolic blood pressure, plasma total cholesterol, calcium and energy intake. The association between AHEI-2010 and AAC severity by DXA was also significant in the multivariate-adjusted model [OR (95% CI) for Tertile 3 VS Tertile 1: 0.38 (0.20-0.70)]. Changes in AHEI-2010 over 18 years were not associated with AAC severity. CONCLUSION Baseline but not the changes in AHEI-2010 was inversely associated with the risk of AAC severity suggesting that a high quality diet might help prevent or delay the progression of AAC in community-dwelling older adults and the benefits might be manifested over the long-term.

Abstract
BACKGROUND Previous studies have shown that skin disease in dermatomyositis (DM) is best assessed using the Cutaneous Dermatomyositis Disease Area and Severity Index (CDASI). Although the CDASI has been validated for use by dermatologists, it has not been validated for use by other physicians such as rheumatologists and neurologists, who also manage patients with DM and assess skin activity in clinical trials. OBJECTIVES To assess the reliability of the CDASI among dermatologists, rheumatologists and neurologists. METHODS Fifteen patients with cutaneous DM were assessed using the CDASI and the Physician Global Assessment (PGA) by five dermatologists, five rheumatologists and five neurologists. RESULTS The mean CDASI activity scores for dermatologists, rheumatologists and neurologists were 21·0, 21·8 and 20·8, respectively. These mean scores were not different among the specialists. The CDASI damage score means for dermatologists, rheumatologists and neurologists were 5·3, 7·0 and 4·8, respectively. The mean scores between dermatologists and rheumatologists were significantly different, but the means between dermatologists and neurologists were not. The intraclass correlation coefficients (ICCs) for interrater reliability for CDASI activity and damage were good to excellent for dermatologists and rheumatologists, and moderate to excellent for neurologists. The ICCs for intrarater reliability for CDASI activity and damage were excellent for dermatologists and rheumatologists and moderate to excellent for neurologists. The PGA displayed lower interrater and intrarater reliability relative to the CDASI. CONCLUSIONS Our results confirm the reliability of the CDASI when used by dermatologists and rheumatologists. The data for its use by neurologists were not as robust.
