Abstract
INTRODUCTION Electrical status epilepticus in sleep (ESES) is an electrographic pattern in which interictal epileptiform activity is augmented by the transition to sleep, with non-rapid eye movement sleep state characterized by near-continuous lateralized or bilateral epileptiform discharges. The aim of this study was to measure the reliability of the spike-wave index (SWI) of the first 100 seconds of sleep as a tool for the diagnosis of ESES. METHODS One hundred forty studies from 60 unique patients met the inclusion. Two neurophysiologists calculated the SWI of the first 100 seconds of spontaneous stage II non-rapid eye movement sleep. This was compared with the SWI of the first 5 minutes of non-rapid eye movement sleep and the cumulative SWI of three 5-minute bins of sleep. Agreement between the three SWI methods were analyzed using several statistical tools and methods. RESULTS Using an SWI of 50% as a diagnostic cutoff, 57% of records had a diagnosis of ESES based on the first 100 seconds of sleep. Fifty-four percent of records had a diagnosis of ESES based on the method of using the SWI of three bins. This resulted in a diagnostic accuracy of 92%, sensitivity of 96%, and specificity of 88%. Positive predictive values of children diagnosed with ESES using the first 100 seconds of sleep, compared with 3 combined bins, was determined to be 90% and a negative predictive value was determined to be 95%. CONCLUSIONS This analysis confirmed the diagnostic accuracy of using the SWI of the first 100 seconds of sleep and the cumulative total of three 5-minute bins.

Abstract
PURPOSE To determine long-term outcome for seizure control and clinical predictors for seizure freedom in patients undergoing surgical treatment for epilepsy associated with hypothalamic hamartoma (HH). METHODS 155 patients underwent surgical treatment for HHs and treatment-resistant epilepsy at one center (Barrow Neurological Institute at St. Joseph's Hospital and Medical Center, Phoenix, Arizona, USA) between February 2003 and June 2010. Data collection included medical record review and direct follow-up interviews to determine seizure outcome. Statistical analysis included descriptive summaries of patient characteristics and time-to-event analysis for seizure freedom. RESULTS Long-term survival with follow-up of at least five years since first surgical treatment was available for 108 patients (69.7% of the treatment cohort). The surgical approach for first HH intervention consisted of transventricular endoscopic resection (n = 57; 52.8%), transcallosal interforniceal resection (n = 35; 32.4%), pterional resection (n = 7; 6.5%), and gamma knife radiosurgery (n = 9; 8.3%). Multiple surgical procedures were required for 39 patients (36.1%). There were 10 known deaths from all causes in the treatment cohort (6.5%). Of these, one (0.6%) was related to immediate complications of HH surgery, three (1.9%) were attributed to Sudden Unexpected Death in Epileptic Persons (SUDEP), and one (0.6%) to complications of status epilepticus. For surviving patients with long-term follow-up, 55 (50.9%) were seizure-free for all seizure types. Univariable analysis showed that seizure-freedom was related to 1) absence of a pre-operative history for central precocious puberty (p = 0.01), and 2) higher percentage of HH lesion disconnection after surgery (p = 0.047). Kaplan-Meier survival analysis shows that long-term seizure outcome following HH surgery is comparable to short-term results. SUMMARY These uncontrolled observational results show that long-term seizure control following HH surgical treatment is comparable to other forms of epilepsy surgery. Late relapse (at least one year after surgery) and SUDEP do occur, but in a relatively small number of treated patients. These results inform clinical practice and serve as a comparable benchmark for newer technologies for HH surgery, such as magnetic resonance imaging-guided laser interstitial thermal therapy, where long-term outcome results are not yet available.

Abstract
Neutrophils are key first responders to Clostridioides difficile infection (CDI). Excessive tissue and blood neutrophils are associated with worse histopathology and adverse outcomes, however their functional role during CDI remains poorly defined. Utilizing intestinal epithelial cell (IEC)-neutrophil co-cultures and a pre-clinical animal model of CDI, we show that neutrophils exacerbate C. difficile -induced IEC injury. We utilized cutting-edge single-cell transcriptomics to illuminate neutrophil subtypes and biological pathways that could exacerbate CDI-associated IEC damage. As such, we have established the first transcriptomics atlas of bone marrow (BM), blood, and colonic neutrophils after CDI. We found that CDI altered the developmental trajectory of BM and blood neutrophils towards populations that exhibit gene signatures associated with pro-inflammatory responses and neutrophil-mediated tissue damage. Similarly, the transcriptomic signature of colonic neutrophils was consistent with hyper-inflammatory and highly differentiated cells that had amplified expression of cytokine-mediated signaling and degranulation priming genes. One of the top 10 variable features in colonic neutrophils was the gene for neutrophil glycoprotein, Olfactomedin 4 (OLFM4). CDI enhanced OLFM4 mRNA and protein expression in neutrophils, and OLFM4 + cells aggregated to areas of severe IEC damage. Compared to uninfected controls, both humans and mice with CDI had higher concentrations of circulating OLFM4; and in mice, OLFM4 deficiency resulted in faster recovery and better survival after infection. Collectively, these studies provide novel insights into neutrophil-mediated pathology after CDI and highlight the pathogenic role of OLFM4 + neutrophils in regulating CDI-induced IEC damage. One Sentence Summary Utilizing single-cell transcriptomics, IEC-epithelial co-cultures, and pre-clinical models of CDI, we have identified a subset of neutrophils that are marked by OLFM4 expression as pathogenic determinants of IEC barrier damage after CDI.

Abstract
Background and Objectives Folic acid is an important supplement to take for women with epilepsy on antiseizure medications (ASMs). Determination of baseline counseling given to women with epilepsy and the association with folic acid being recommended were evaluated. Factors surrounding the association were reviewed. Methods An exploratory retrospective review of women with epilepsy seen at a large Midwestern pediatric institution was performed between January 2018 and January 2020. Results Patients who received preconception counseling were more likely to be given a recommendation to take folic acid. Patients on more than 1 ASM were likely to receive counseling. Patient age and race were associated with having folic acid recommended. Discussion Providing preconception counseling for women with epilepsy is associated with an increased recommendation and prescription of folic acid. Further evaluation into possible disparities to receiving a folic acid recommendation is needed.

Abstract
BACKGROUND AND OBJECTIVES The ideal duration of neoadjuvant chemotherapy (NACT) in patients with localized pancreatic adenocarcinoma (PDAC) treated with curative intent is unclear. We sought to determine the prognostic significance of both duration of NACT and Carbohydrate Antigen 19-9 (CA19-9) normalization to NACT. METHODS We examined patients with resectable and borderline resectable PDAC treated with NACT and chemoradiation. Patients were compared by NACT duration (2 vs 4 months) and by CA19-9 normalization after NACT. RESULTS Among 171 patients, 83 (49%) received two months of NACT and 88 (51%) received four months. After NACT completion, 115 (67%) patients had persistently elevated CA19-9 and 56 (33%) had normalized. Of the 125 patients who had successful surgery, 73 (58%) had normalized CA19-9 postoperatively. Duration of NACT was not associated with overall survival (OS) while CA19-9 normalization after NACT (regardless of duration) was associated with improved OS (HR 0.56, 95% CI 0.35-0.89, p=0.02). Adjuvant chemotherapy was associated with improved OS among patients without CA19-9 normalization after NACT (HR 0.42, CI 0.20-0.86, p=0.02) but not among those that normalized, independent of duration. CONCLUSIONS CA19-9 normalization after NACT is a clinically significant endpoint of treatment; patients without CA19-9 normalization may benefit from additional therapy.

Abstract
ALG6-CDG is a rare, but second most common, type 1 congenital disorder of glycosylation (CDG) caused by a defect in the α-1-3-glucosyltransferase (ALG6) enzyme in the N-glycan assembly pathway. Many mutations have been identified and inherited in an autosomal recessive pattern. There are less than 100 ALG6-CDG cases reported, all sharing the phenotype of hypotonia and developmental delay. The majority (perhaps >70%) have seizures, but a minority have intractable epilepsy or epileptic encephalopathy. We report the clinical course, EEG findings, and neuroimaging of a child found to have compound heterozygous alleles c.257 + 5G > A and c.680G > A (p.G227E) who developed explosive onset of intractable epilepsy and epileptic encephalopathy. Initially, CDG was not suspected due to its rarity and lack of multi-organ system involvement, but rapid whole exam sequence (8-day turnaround) revealed the specific diagnosis quickly.

Abstract
Introduction
Colorectal carcinoma is one of the most commonly diagnosed cancers. Metastasis is seen in the liver, lung, peritonium and bone. Though skeletal muscles make up a majority of our body mass, they are an extremely rare site for metastasis
A 74 y/male known to have total ulcerative colitis was put on the 2WW due to change in bowel habits, weight loss and anemia. Investigations revealed a large cavitating lesion in the right colon with no evidence of metastasis. He underwent an open total pan procto-colectomy, small bowel resection and end ileostomy
Histopathology showed the tumour was a completely excised adenocarcinoma
During surveillance it was noted his CEA levels were high, for which he had a host of investigations including a CT scan and a PET scan, all of which had no interval changes.
He mentioned that he noticed a lump in his left thigh. Orthopedicians advised an MRI scan which showed a tissue lump covering the front of the thigh, within the vastus medialis.
A biopsy revealed metastatic adenocarcinoma.
He also had left wrist pain. A thorough examination revealed a hard mass within the swelling. Ultrasound confirmed a solid well circumscribed mass with vascularity.
Given the above information the patient felt he would be like to complete the remaining of his life with dignity and comfort at home and was fast-track discharged.
Discussion
Skeletal muscle metastasis of colorectal cancers is always associated with a prognosis that is somber and terminal. A high degree of suspicion is needed for diagnosis.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
AIMS To improve the timeliness and quality of discharge for patients by creating the role of the Attending Nurse. BACKGROUND Discharge time affects hospital throughput and patient satisfaction. Bedside nurses and hospitalists have competing priorities that can hinder performing timely, high quality discharges. METHODS This retrospective analysis evaluated the effect of an Attending Nurse paired with a hospital medicine physician on discharge time and quality. A total of 8329 patient discharges were eligible for the study and propensity score matching yielded 2715 matched pairs. RESULTS In the post- intervention matched cohort, the percentage of patients discharged before 2pm increased from 34.4% to 45.9% (p <0.01) and the median discharge time moved 48 minutes earlier. In the unmatched cohort, patient satisfaction with the discharge process improved on several questions. While length of stay was not affected, the 30-day readmission rate did increase from 8.9% to 10.7% (p=0.02). CONCLUSION With the new Attending Nurse role, we positively impacted throughput by shifting discharge times earlier in the day while improving patient satisfaction Length of stay stayed the same but the 30-day readmission rate increased. IMPLICATIONS FOR NURSING MANAGEMENT Our multidisciplinary approach to the problem of late discharge times led to the creation of a new role. This role made ownership of discharge tasks clear and reduced competing priorities, freeing up nurses and hospitalists to perform other care related responsibilities without holding up discharges.

Background/Introduction
Non-vitamin K antagonist oral anticoagulants (NOACs) are class I recommended by various guidelines for stroke prevention in atrial fibrillation. NOACs are associated with comparable or lower risk of stroke / systemic embolism and significantly lower major bleeding as compared to VKAs. Despite the fact that NOACs have demonstrated safety and efficacy in stroke prevention in AF by various randomized clinical trials and real-world evidences, the pharmacoeconomic data of NOACs in stroke prevention is lacking in India. In view of the higher initial and long-term cost of the NOAC therapy, it is important to analyze the cost effectiveness of such therapy to ensure wider acceptance and compliance to medication since majority of population in India is self-paying.
Purpose
The aim of this study was to evaluate the cost-effectiveness of apixaban versus other NOACs available in India (dabigatran and rivaroxaban), warfarin and aspirin for stroke prevention in atrial fibrillation from the healthcare providers’ and patients’ perspectives in the government healthcare as well as the private healthcare facilities across Indian subcontinent.
Methods
A Markov model was constructed using six-week cycle length over a lifetime horizon by including the available data from RCTs and real-world analyses of all NOACs. The clinical consequences of AF included in the analysis were stroke (ischemic and hemorrhagic), systemic embolism, bleeding (intracranial hemorrhage, other major and clinically relevant non-major), myocardial infarction, mortality and morbidity associated with NVAF not on anticoagulant. Innovator brands of NOACs were considered for this analysis, as NOACs are not under price control in India unlike warfarin and aspirin. Model outputs included quality-adjusted life years (QALY), life years gained, direct medical costs and incremental cost-effectiveness ratios (ICERs). Additional sensitivity and scenario analyses were conducted to test the robustness of the outcomes.
Results
From healthcare provider’s perspective irrespective of private medical facility or the government healthcare facilities, Apixaban was dominantly associated with cost-saving over other OACs. Apixaban was cost effective as compared to warfarin from patients’ perspective at the private medical facilities. Apixaban was cost-effective compared to dabigatran and rivaroxaban from patients’ perspective in the RWE-based analysis.
Conclusion
We conclude that apixaban is cost saving (less costly and more effective) compared to warfarin, aspirin and other NOACs from healthcare providers’ perspective. Apixaban may be a cost-effective alternative to dabigatran and rivaroxaban from patients’ perspective as per the RWD-based cost-effectiveness analysis. These conclusions are based on indirect comparisons, but despite this limitation, the information is useful for healthcare professionals and decision-makers. Abstract Figure.

Abstract
Abstract
Aim
There is an increase in the number of complex SPECC cases presented at colorectal MDT meetings with a wide variation in the treatments offered to patients, many of whom undergo high-risk and life-changing surgical resection. This study aimed to evaluate the detection, diagnosis and treatment of early colorectal cancer since the introduction of a SPECC MDT.
Method
This was a retrospective audit of 108 patients, from the SPECC MDT database from January 2014 to December 2019. Primary outcome assessed the recognition of lesions using endoscopy and radiological evaluation to assess depth of invasion and lymph node involvement. Secondary outcomes included definite treatment, pathological reporting and recurrence.
Results
Overall, mean age of 72, 79% had one or more significant co-morbidity. Clinical presentation; 61 asymptomatic, 46 symptomatic and 31 referred from the national bowel cancer-screening programme. All patients (n = 108) had endoscopic assessment the lesions were, 53% sessile and 47% pedunculated; 78% of the lesions were found in the rectum. We observed surgical management in 31 cases, endoscopic in 28, chemo-radiotherapy in 12 and 3 cases were palliative. However, 17 (n = 108) underwent failed endoscopic resection and required surgical intervention. Recurrence was observed in 17.6% of cases and mortality in 4%.
Conclusions
Pathological reports provide a definitive answer to questions of malignancy but SPECC can be challenging in all areas. A specialist MDT allows for appropriate assessment and treatment of lesions and leads to better patient outcomes.

Abstract
Abstract
Introduction
Port site hernias containing the appendix are sporadically described in the literature, with most cases presenting with acute appendicitis. Cases of a normal appendix being found in such hernias are extremely rare and rarely published. Here we describe a patient with a port site hernia containing a non-inflamed appendix. The lack of similar recorded cases makes this a unique case to highlight and discuss.
Case Description
81-year-old lady, with adenocarcinoma of the upper rectum, underwent a laparoscopic high anterior resection in late 2018. With 12 mm ports placed in Umbilicus and RIF. 5mm ports placed in RUQ and LUQ. The 12 mm ports were closed with deep suture closure and the skin was closed using clips. Computerised tomography (CT) imaging at one year showed local cancer recurrence and a small abdominal wall hernia in the right iliac fossa. During subsequent resection surgery, a RIF port site hernia was identified intraoperatively. The hernia sac consisted of an uninflamed appendix. The hernia was reduced and an appendicectomy was performed with the hernia being closed with interrupted suture closure. Histology of the appendix confirmed no evidence of inflammation.
Discussion
When a clinical rarity is encountered there is often minimal literature to guide management and decisions must be made based on surgical principles and clinical reasoning. Although here an appendicectomy was performed, resection of a normal appendix remains a contentious point in the surgical field. This case demonstrates a potential management option to guide surgeons who encounter this clinical rarity in their future practice.

Abstract
AbstractElectrical status epilepticus during sleep (ESES) is an age-related, self-limited epileptic encephalopathy characterized by heterogeneous clinical manifestations and a specific electroencephalographic pattern of continuous spikes and waves during slow sleep. The etiology of ESES is not completely clear, although structural brain lesions, abnormal immunological markers, and genetic mutations have been associated with the syndrome. ESES was first described in 1971 and since then, the diagnostic criteria have changed multiple times. Additionally, inconsistency between authors in how to record and evaluate the electroencephalogram also leads to variability between studies. These inconsistencies hamper objectivity, comparison, and generalization. Because of this, one of the first priorities of physicians treating this condition should be defining the parameters of this disease so that cooperative building can occur.

Abstract
Abstract
Introduction
Updated guidelines published by the National Institute for Health and Care Excellence in 2015 widened the referral criteria for the two week wait (2WW) pathway for suspected lower gastrointestinal cancer, in an attempt to increase early diagnosis. The aim of this study was to evaluate the compliance of referrals received via the (2WW) pathway for suspected lower gastrointestinal cancer.
Method
We conducted a retrospective study which utilised a local cancer registry to identify all patients who had been referred to United Lincolnshire Hospitals Trust over a two-month period. Electronic patient records were checked to establish whether patients fulfilled the 2015 referral criteria.
Results
Out of 615 patients referred, 51 (8%) had colorectal cancer. 92 (15%) referrals did not meet the criteria for the 2WW pathway. Whether or not the referral was ‘appropriate’ had no significant effect on the diagnoses of bowel cancer (X2 = .003, p>.05).
Conclusions
16% of all referrals did not meet criteria. This may appear as an inefficient use of resources, however there was no difference in rates of cancer between appropriate and inappropriate referrals. The referral criteria are likely to evolve over the course of time, and perhaps clinicians’ judgement should be taken into account.

Abstract
Background:Clinical profile of myositis differs in respect of the setting. We present a single center experience from a community based referral centerObjectives:STUDY CLINICAL PROFILE OF INFLAMMATORY MYOSITIS (IM)Methods:We present data from 114 patients of connective tissue disorders (CTD) with dominant Inflammatory Myopathy(IM) evaluated in CRD where we have patient database since 1996. Standard investigations & ELISA, immunoblot and nephlometry to assay autoantibodies (AAb) were done. Data extraction done from 2005-2017Results:36 and 28 patients respectively diagnosed as dominant idiopathic dematomyositis (DM) and polymyositis (PM); remaining 41 patients showed overlap (OCTD). Mean onset age range 33-40 years in each subset with women dominance. Exclusive proximal muscle involvement seen 64% DM, 67% PM and 43% OCTD. 12 of OCTD showed classical DM rash. Raynauds’s phenomenon was seen in 38% (25% DM, 10% PM, 65% OCTD). 83% OCTD showed inflammatory polyarthritis; DM 29% and PM 42%. Two patients DM also diagnosed malignancy (ovarian CA). 25% DM, nil PM and 31.7% OCTD showed CT based lung findings. Mean creatinine phosphokinase at diagnosis were DM 1580, PM 2239 & OCTD 830. EMG required in 48 patients confirmed diagnosis (DM 17, PM 16 and OCTD 15). Seven patients with diagnostic dilemma/ poor therapy response required muscle histopathology confirmation. 59% DM,69% PM and 84% OCTD were seropositive ANA positive in 71%(ENA profile available for most). All Patients received steroids. Methotrexate prescribed in (92%), Azthioprine in (28%), hydroxychloroquine in (88%) with majority showing good response. Mycophenolate prescribed in (6%) for aggressive disease, IVIG in 2 patients for acute IIM with interstitial pneumonitis. Rituximab was prescribed in 4 resistant cases; all responding favourably. Mortality data of 4 patients(severe myositis(1), interstitial pneumonitis(1), ovarian cancer(1), septic shock(1)) was available. Antesynthatase syndrome noted in 9 patients.Conclusion:Overlap CTD with myositis seems more common profile than DM or PM. Response to therapy was satisfactory with steroids and methotrexate being the mainstay. Rituximab is a promising biological agent in chronic resistant cases.References:[1]A Kumar.

Abstract
Benign familial neonatal epilepsy is a syndrome characterized by recurrent seizures
occurring in the neonatal period. Seizures commonly begin at day 3 of life and usually
abate by 1 to 4 months of life. Seizures are usually described as tonic with an asymmetric
component with associated autonomic features. The authors report a newborn presenting with
an unusual electroclinical phenotype. The electroencephalogram demonstrated an unusual
pattern of electrical attenuation at the onset of seizures. Identification of these
features is important for early recognition of this neonatal syndrome, as well as
initiation of proper therapy.

Abstract
Antineutrophil cytoplasmic antibody (ANCA)-associated glomerulonephritis in a patient of scleroderma is very rare. Very few cases have been reported in English literature. We report a case of a 58-year-old male with long-standing limited cutaneous scleroderma (Scl-70 positive) presenting with normotensive scleroderma renal crisis. Perinuclear ANCA with antimyeloperoxidase antibody was found to be strongly positive. Renal biopsy showed pauci immune-necrotizing crescentic glomerulonephritis. We believe that this case report will be helpful in understanding clinical features of normotensive ANCA-associated glomerulonephritis in scleroderma patients.

Abstract
GNAO1, located on chromosome 16q12.2, encodes for 1 of the heterotrimeric guanine binding proteins subunits (G proteins), specifically Gαo, which has been implicated as having an important role in brain function. GNAO1 mutations have been shown to impart oncogene properties as well as cause epileptic encephalopathy. The authors report 2 cases of brothers with a severe movement disorder and hypotonia without epilepsy who have been confirmed by whole exome sequencing to have a novel mutation in GNAO1. Their movement disorder improved significantly with deep brain stimulation.

Abstract
PURPOSE Aicardi syndrome (AIC) is a congenital neurodevelopmental disorder characterized by infantile spasms, agenesis of the corpus callosum, and chorioretinal lacunae. Variation in phenotype and disease severity is well documented, but chorioretinal lacunae represent the most constant pathological feature. Aicardi syndrome is believed to be an X-linked-dominant disorder occurring almost exclusively in females, although 46, XY males with AIC have been described. The purpose of this study is to identify genetic factors and pathways involved in AIC. METHODS We performed exome/genome sequencing of 10 children diagnosed with AIC and their parents and performed RNA sequencing on blood samples from nine cases, their parents, and unrelated controls. RESULTS We identified a de novo mutation in autosomal gene TEAD1, expressed in the retina and brain, in a patient with AIC. Mutations in TEAD1 have previously been associated with Sveinsson's chorioretinal atrophy, characterized by chorioretinal degeneration. This demonstrates that TEAD1 mutations can lead to different chorioretinal complications. In addition, we found that altered expression of genes associated with synaptic plasticity, neuronal development, retinal development, and cell cycle control/apoptosis is an important underlying potential pathogenic mechanism shared among cases. Last, we found a case with skewed X inactivation, supporting the idea that nonrandom X inactivation might be important in AIC. CONCLUSIONS We expand the phenotype of TEAD1 mutations, demonstrate its importance in chorioretinal complications, and propose the first putative pathogenic mechanisms underlying AIC. Our data suggest that AIC is a genetically heterogeneous disease and is not restricted to the X chromosome, and that TEAD1 mutations may be present in male patients.

Abstract
The role of non-invasive methods in the investigation of acute effects of traffic-related air pollution is not clearly established. We evaluated the usefulness of non-invasive biomarkers in detecting acute air pollution effects according to the age of participants, the disease status, their sensitivity compared with lung function tests and their specificity for a type of pollutant. Search terms lead to 535 titles, among them 128 had potentially relevant abstracts. Sixtynine full papers were reviewed, while 59 articles were excluded as they did not meet the selection criteria. Methods used to assess short-term effects of air pollution included analysis of nasal lavage (NAL) for the upper airways, and induced sputum (IS), exhaled breath condensate (EBC) and exhaled nitric oxide (FeNO) for central and lower airways. There is strong evidence that FeNO evaluation is useful independently from subject age, while IS analysis is suitable almost for adults. Biomarker changes are generally observed upon pollutant exposure irrespective of the disease status of the participants. None of the biomarkers identified are specific for a type of pollutant exposure. Based on experimental exposure studies, there is moderate evidence that IS analysis is more sensitive than lung function tests, whereas this is not the case for biomarkers obtained by NAL or EBC. Cells and some cytokines (IL-6, IL-8 and myeloperoxidase) have been measured both in the upper respiratory tract (NAL) and in the lower airways (IS). Overall, the response to traffic exposure seems different in the two compartments. In conclusion, this survey of current literature displays the complexity of this research field, highlights the significance of short-term studies on traffic pollution and gives important tips when planning studies to detect acute respiratory effects of air pollution in a non-invasive way.

Abstract
We measure the time dependence of the ratio of decay rates for D0→K(+)π(-) to the Cabibbo-favored decay D(0)→K(-)π(+). The charge conjugate decays are included. A signal of 3.3×10(4) D(*+)→π(+)D(0), D(0)→K(+)π(-) decays is obtained with D0 proper decay times between 0.75 and 10 mean D0 lifetimes. The data were recorded with the CDF II detector at the Fermilab Tevatron and correspond to an integrated luminosity of 9.6 fb(-1) for pp¯ collisions at √s=1.96 TeV. Assuming CP conservation, we search for D0-D¯0 mixing and measure the mixing parameters to be R(D)=(3.51±0.35)×10(-3), y'=(4.3±4.3)×10(-3), and x'2=(0.08±0.18)×10(-3). We report Bayesian probability intervals in the x'2-y' plane and find that the significance of excluding the no-mixing hypothesis is equivalent to 6.1 Gaussian standard deviations, providing the second observation of D0-D¯0 mixing from a single experiment.

Molecular markers as intermediate end-points in chemoprevention of colon-cancer - modulation of ras activation by sulindac and phenylhexylisothiocyanate during colon carcinogenesis.

Abstract
Recent evidence suggests that activation of ras proto-oncogenes and inactivation of suppressor genes induce malignant phenotype in colonic cells. Thus the identification of clonal population of cells expressing activated ras may lead to a valuable intermediate biomarker to detect premalignant lesions amenable to chemoprevention. Previously, we demonstrated that sulindac inhibited the carcinogen-induced colon tumor development whereas phenylhexylisothiocyanate (PHITC) promoted the tumor outcome. The present study was conducted to investigate the effect of sulindac and PHITC on azoxymethane (AOM)induced activation of ras proto-oncogenes in order to explore the plausibility of using ras as an intermediate biomarker in chemoprevention of colon cancer. Male F344 rats were fed the AIN-76A diet containing 0, 320 ppm sulindac or 640 ppm PHITC and administered s.c. AOM dissolved in normal saline at a dose rate of 15 mg/kg body wt/week for 2 weeks. Vehicle control groups received s.c. equal volume of normal saline. Animals were sacrificed 52 weeks after AOM or saline treatment and their colonic mucosa and tumors were analyzed for mutations in codon 12 and 13 of K-ras and the expression of ras p21. As an alternative non-invasive approach, we developed a simple and sensitive one-step mutant-enriched PCR method to detect these genetic lesions in stools collected at 16, and again at 24 weeks after AOM treatment. AOM-induced G to A transitions were observed at the second nucleotide of 12th codon of K-ras substituting amino acid asp with wild-type gly. Sulindac not only suppressed the selective amplification of initiated cells possessing AOM-induced mutated K-ras codon 12, but significantly inhibited the AOM-induced expression of total and mutant ras-p21. PHITC did not exert any inhibitory effect on AOM-induced ras activation. Results indicated a strong correlation between ras activation and tumor outcome. Data suggest that ras activation may be a useful intermediate molecular marker in chemoprevention of colon cancer.

Abstract
Several studies have successfully employed GM1 ganglioside to treat animal models of Parkinson's disease (PD), suggesting involvement of this ganglioside in PD etiology. We recently demonstrated that genetically engineered mice (B4galnt1(-/-) ) devoid of GM1 acquire characteristic symptoms of this disorder, including motor impairment, depletion of striatal dopamine, selective loss of tyrosine hydroxylase-expressing neurons, and aggregation of α-synuclein. The present study demonstrates similar symptoms in heterozygous mice (HTs) that express only partial GM1 deficiency. Symptoms were alleviated by administration of L-dopa or LIGA-20, a membrane-permeable analog of GM1 that penetrates the blood-brain barrier and accesses intracellular compartments. Immunohistochemical analysis of paraffin sections from PD patients revealed significant GM1 deficiency in nigral dopaminergic neurons compared with age-matched controls. This was comparable to the GM1 deficiency of HT mice and suggests that GM1 deficiency may be a contributing factor to idiopathic PD. We propose that HT mice with partial GM1 deficiency constitute an especially useful model for PD, reflecting the actual pathophysiology of this disorder. The results point to membrane-permeable analogs of GM1 as holding promise as a form of GM1 replacement therapy.

Abstract
Flunisolide (6α-fluorine 11β, 16α, 17α, 21-tetrahydroxypregna-1, 4-diene-3.20-dione 16.17 acetonide) is a potent inhaled corticosteroid, as demonstrated by its anti-inflammatory activities. Clinical data have widely demonstrated that inhaled flunisolide administered twice daily is effective for the treatment of bronchial asthma. However, pharmacokinetic studies suggest that the high solubility rate of flunisolde in bronchial fluid reduces the residence time of the drug in the lungs to a few minutes. The aim of this study is to determine the concentration of flunisolide in lung tissue of rats after administration by inhalation at varying time periods. Male Wistar rats weighing approximately 300 g were divided into four groups and administered a single dose of 1 mg flunisolide via inhalation. Rats were sacrificed with the exposure to CO2 either immediately or 3,6,12 hours after inhalation. The whole lung was then surgically removed and analysed for flunisolide concentration using gas chromatography. The mean concentration (2 standard deviation) of flunisolide detected in the lung tissue at 0, 3, 6 hours after inhalation were 66.4 (11.9), 48.6 (5.9), 42.7 (8.1) ng/mg of proteins, respectively. No flunisolide was detected after 12 hours in lung tissue. We conclude that flunisolide is retained for long duration (more than 6 hours) in lung tissue. This finding partially explains the mechanisms of action of the drug.

Abstract
BACKGROUND To assess the plaque and salivary pH changes at different time intervals in vivo after consumption of a carbonated beverage modified with sodium fluoride and calcium phosphate. MATERIALS AND METHODS Twenty-four subjects aged 18-25 years were recruited and randomly assigned to three groups (group A, original drink Sprite; group B, Sprite with sodium fluoride; group C, Sprite with calcium phosphate). Collection of pooled plaque and unstimulated saliva was done before and after the drinks were consumed by the subjects at 5-, 10-, 20- and 30-minute intervals. RESULTS The pH rise was higher with group C for plaque and group B for saliva. CONCLUSIONS Modification of the test carbonated beverage with calcium phosphate and fluoride may exert some protective potential, especially in high caries risk candidates.

Abstract
Parkinson's disease (PD) is the second most prevalent late-onset neurodegenerative disorder that affects nearly 1% of the global population aged 65 and older. Whereas palliative treatments are in use, the goal of blocking progression of motor and cognitive disability remains unfulfilled. A better understanding of the basic pathophysiological mechanisms underlying PD would help to advance that goal. The present study provides evidence that brain ganglioside abnormality, in particular GM1, may be involved. This is based on use of the genetically altered mice with disrupted gene Galgt1 for GM2/GD2 synthase which depletes GM2/GD2 and all the gangliotetraose gangliosides that constitute the major molecular species of brain. These knockout mice show overt motor disability on aging and clear indications of motor impairment with appropriate testing at an earlier age. This disability was rectified by L-dopa administration. These mice show other characteristic symptoms of PD, including depletion of striatal dopamine (DA), loss of DA neurons of the substantia nigra pars compacta, and aggregation of alpha synuclein. These manifestations of parkinsonism were largely attenuated by administration of LIGA-20, a membrane permeable analog of GM1 that penetrates the blood brain barrier and enters living neurons. These results suggest that perturbation of intracellular mechanisms mediated by intracellular GM1 may be a contributing factor to PD.

Abstract
The T2K experiment observes indications of ν(μ) → ν(e) appearance in data accumulated with 1.43×10(20) protons on target. Six events pass all selection criteria at the far detector. In a three-flavor neutrino oscillation scenario with |Δm(23)(2)| = 2.4×10(-3) eV(2), sin(2)2θ(23) = 1 and sin(2)2θ(13) = 0, the expected number of such events is 1.5±0.3(syst). Under this hypothesis, the probability to observe six or more candidate events is 7×10(-3), equivalent to 2.5σ significance. At 90% C.L., the data are consistent with 0.03(0.04) < sin(2)2θ(13) < 0.28(0.34) for δ(CP) = 0 and a normal (inverted) hierarchy.

Abstract
Measurements of the local susceptibility and 3d spin relaxation rate for single Fe impurities embedded in a nanocrystalline Nb host indicates the emergence of a local moment on Fe at and below a critical size of 11 nm. Our ab initio electronic structure calculations show that the moment formation occurs due to Stoner enhancement arising from a size dependent lattice expansion and a consequent shift in the Fermi level. We also show that a size-induced positive host spin polarization of the Nb-4d band electrons strongly influences the fluctuation rate of the Fe moment.

Abstract
BACKGROUND Interdisciplinary communication is critically important to provide safe and effective care, yet it has been inadequately studied for hospitalised medical patients. Our objective was to characterise nurse-physician communication and their agreement on patients' plan of care. METHODS During a one-month period, randomly selected hospitalised patients, their nurses and their physicians were interviewed. Nurses and physicians were asked to identify one another, whether communication had occurred, and about six aspects of the plan of care. Two internists rated nurse-physician agreement on aspects of the plan of care as none, partial or complete agreement. Measures included the percentage of nurses and physicians able to identify one another and reporting communication and the percentage of nurse-physician pairs in agreement on aspects of the plan of care. RESULTS 310 (91%) and 301 (88%) of 342 eligible nurses and physicians completed interviews. Nurses correctly identified patients' physicians 71% of the time and reported communicating with them 50% of the time. Physicians correctly identified the patients' nurses 36% of the time and reported communicating with them 62% of the time. Physicians and nurses showed no agreement on aspects of the plan of care ranging from 11% for planned procedures to 42% for medication changes. CONCLUSIONS Nurses and physicians did not reliably communicate with one another and were often not in agreement on the plan of care for hospitalised medical patients.

Abstract
BACKGROUND The burning of biomass fuels results in exposure to high levels of indoor air pollution, with consequent health effects. Possible interventions to reduce the exposure include changing cooking practices and introduction of smoke-free stoves supported by health education. Social, cultural and financial constraints are major challenges to implementation and success of interventions. The objective of this study is to determine awareness of women in Gondar, Ethiopia to the harmful health effects of cooking smoke and to assess their willingness to change cooking practices. METHODS We used a single, administered questionnaire which included questions on household circumstances, general health, awareness of health impact of cooking smoke and willingness to change. We interviewed 15 women from each of rural, urban-traditional and middle class backgrounds. RESULTS Eighty percent of rural women cooked indoors using biomass fuel with no ventilation. Rural women reported two to three times more respiratory disease in their children and in themselves compared to the other two groups. Although aware of the negative effect of smoke on their own health, only 20% of participants realised it caused problems in children, and 13% thought it was a cause for concern. Once aware of adverse effects, women were willing to change cooking practices but were unable to afford cleaner fuels or improved stoves. CONCLUSION Increasing the awareness of the health-effects of indoor biomass cooking smoke may be the first step in implementing a programme to reduce exposure.

Abstract
Eighteen bacterial strains were isolated from soil samples and screened for alkaline, thermophilic lipase production. Pseudomonas fluorescens NS2W was selected and its production of lipase was optimized in shake flasks using a statistical experimental design. Cell growth and lipase production were studied in shake flasks and in a 1-l fermenter in the optimized medium. Maximum lipase yields were 69.7 and 68.7 U ml(-1), respectively. The optimized medium resulted in about a five-fold increase in the enzyme production, compared to that obtained in the basal medium. The lipase had an optimal activity at pH 9.0 and was stable over a wide pH range of 3-11 with more than 70% activity retention. The lipase had an optimal activity at 55 degrees C and was stable up to 60 degrees C with more than 70% activity retention for at least 2 h.

Abstract
OBJECTIVE This study was undertaken to determine whether surgery for advanced pelvic organ prolapse corrects the voiding dysfunction commonly associated with this condition and if so to evaluate the ability of preoperative voiding studies to predict such correction. STUDY DESIGN We reviewed the records of all women who underwent surgery at our center between January 1996 and June 1999 for stage 3 or 4 pelvic organ prolapse. Patients were included in this review if they had a postvoid residual volume of >100 mL documented by catheterization on at least 2 occasions, had no normal postvoid residual volumes documented, and had undergone preoperative multichannel urodynamic testing that included an instrumented voiding study. Demographic and urodynamic data were analyzed for the ability to predict whether the elevated postvoid residual volume would be resolved after surgery. RESULTS Thirty-five patients satisfied the criteria for inclusion in the review. Twenty-six had stage 3 pelvic organ prolapse and 9 had stage 4 pelvic organ prolapse. The mean preoperative postvoid residual volume was 226 mL (range, 105-600 mL). Thirty-one patients (89%) had normal postvoid residual volumes after surgery. As a predictor of elevated postoperative postvoid residual volumes, the preoperative voiding study (performed with the prolapse reduced) had a sensitivity of 66%, a specificity of 46%, a positive predictive value of 12%, and a negative predictive value of 93%. CONCLUSION In our center a preoperative voiding study performed with the pelvic organ prolapse reduced most accurately predicted postoperative voiding function when results of the voiding study were normal. Most patients with advanced pelvic organ prolapse and elevated postvoid residual volume had normalization of the postvoid residual volume after surgical correction of the pelvic organ prolapse.
