Abstract
OBJECTIVES To describe daily environmental cleaning and disinfection practices and their associations with cleaning rates while exploring contextual factors experienced by healthcare workers involved in the cleaning process. METHODS A convergent mixed methods approach using quantitative observations (ie, direct observation of environmental service staff performing environmental cleaning using a standardized observation form) and qualitative interviews (ie, semistructured interviews of key healthcare workers) across 3 Veterans Affairs acute and long-term care facilities. RESULTS Between December 2018 and May 2019 a total of sixty-two room observations (N = 3602 surfaces) were conducted. The average observed surface cleaning rate during daily cleaning in patient rooms was 33.6% for all environmental surfaces and 60.0% for high-touch surfaces (HTS). Higher cleaning rates were observed with bathroom surfaces (Odds Ratio OR = 3.23), HTSs (OR = 1.57), and reusable medical equipment (RME) (OR = 1.40). Lower cleaning rates were observed when cleaning semiprivate rooms (OR = 0.71) and rooms in AC (OR = 0.56). In analysis stratified by patient presence (ie, present, or absent) in the room during cleaning, patient absence was associated with higher cleaning rates for HTSs (OR = 1.71). In addition, the odds that bathroom surfaces being cleaned more frequently than bedroom surfaces decreased (OR = 1.97) as well as the odds that private rooms being cleaned more frequently than semi-private rooms also decreased (OR = 0.26; 0.07-0.93). Between January and June 2019 eighteen qualitative interviews were conducted and found key themes (ie, patient presence and semiprivate rooms) as potential barriers to cleaning; this supports findings from the quantitative analysis. CONCLUSION Overall observed rates of daily cleaning of environmental surfaces in both acute and long-term care was low. Standardized environmental cleaning practices to address known barriers, specifically cleaning practices when patients are present in rooms and semi-private rooms are needed to achieve improvements in cleaning rates.

Abstract
In-situ study of comet 1P/Halley during its 1986 apparition revealed a surprising abundance of organic coma species. It remained unclear, whether or not these species originated from polymeric matter. Now, high-resolution mass-spectrometric data collected at comet 67P/Churyumov-Gerasimenko by ESA’s Rosetta mission unveil the chemical structure of complex cometary organics. Here, we identify an ensemble of individual molecules with masses up to 140 Da while demonstrating inconsistency of the data with relevant amounts of polymeric matter. The ensemble has an average composition of C1H1.56O0.134N0.046S0.017, identical to meteoritic soluble organic matter, and includes a plethora of chain-based, cyclic, and aromatic hydrocarbons at an approximate ratio of 6:3:1. Its compositional and structural properties, except for the H/C ratio, resemble those of other Solar System reservoirs of organics—from organic material in the Saturnian ring rain to meteoritic soluble and insoluble organic matter –, which is compatible with a shared prestellar history. A new analysis of Rosetta mass spectra reveals an ensemble of complex organic molecules with striking similarities to other organic reservoirs in the Solar System, including Saturn’s ring rain material, pointing at a likely joint prestellar history.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is common in bariatric surgery candidates. We evaluated the effect of sleeve gastrectomy (SG) on NAFLD using validated non-invasive measures. METHODS Patients with morbid obesity and NAFLD, planned for SG, were evaluated before and after surgery. Data collected included anthropometrics, biochemistry, adiponectin, SteatoTest™, NashTest™, FibroTest™, OWLiver® test and real-time ShearWave™ elastography (SWE). RESULTS Twenty-six subjects were included in the study, mean age 44.1 ± 4.8 years, 69.2% males. One year following SG, body mass index decreased significantly from 41.7 ± 4.8 kg/m2 to 29.6 ± 4.5 kg/m2. Concomitantly, significant improvements in triglycerides, ALT, diabetes markers and adiponectin were observed. Mean steatosis, as measured by SteatoTest™, was significantly improved. Steatohepatitis score measured by NashTest™ and OWLiver® significantly decreased. Mean fibrosis, as measured by SWE liver stiffness and FibroTest™, did not change over time. CONCLUSION Steatosis and steatohepatitis are significantly improved by SG as measured by non-invasive measures.

Abstract
CONTEXT Pre-equinox measurements of comet 67P/Churyumov-Gerasimenko with the mass spectrometer ROSINA/DFMS on board the Rosetta spacecraft revealed a strongly heterogeneous coma. The abundances of major and various minor volatile species were found to depend on the latitude and longitude of the nadir point of the spacecraft. The observed time variability of coma species remained consistent for about three months up to equinox. The chemical variability could be generally interpreted in terms of surface temperature and seasonal effects superposed on some kind of chemical heterogeneity of the nucleus. AIMS We compare here pre-equinox (inbound) ROSINA/DFMS measurements from 2014 to measurements taken after the outbound equinox in 2016, both at heliocentric distances larger than 3 AU. For a direct comparison we limit our observations to the southern hemisphere. METHODS We report the similarities and differences in the concentrations and time variability of neutral species under similar insolation conditions (heliocentric distance and season) pre- and post-equinox, and interpret them in light of the previously published observations. In addition, we extend both the pre- and post-equinox analysis by comparing species concentrations with a mixture of CO2 and H2O. RESULTS Our results show significant changes in the abundances of neutral species in the coma from pre- to post-equinox that are indicative of seasonally driven nucleus heterogeneity. CONCLUSIONS The observed pre- and post-equinox patterns can generally be explained by the strong erosion in the southern hemisphere that moves volatile-rich layers near the surface.

Abstract
Duodenal perforation due to biliary stent migration is rare, and it often requires surgical repair; however, endoscopic closure has recently become a viable option in the appropriate patients. We present the case of a 79-year-old female who underwent biliary stent placement for a common bile duct stricture, who subsequently was found to have a duodenal wall perforation secondary to stent migration. The stent was extracted endoscopically with successful defect closure using a ConMed® repositional DuraClip™. We aim to contribute to the limited body of literature that describes endoscopic repair of duodenal perforation secondary to biliary stent migration using through-the-scope endoclips.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
With about 70 million cases of infertility worldwide, half of which are caused by male factors, sperm analysis is critical to determine male fertility potential. Conventional semen analysis methods involve complex and manual inspection with a microscope, and these methods are labor intensive and can take several days. Due to unavailability of rapid, convenient, and user-friendly semen analysis tools, many men do not seek medical evaluation, especially in resource-constrained settings. Furthermore, as conventional methods have to be conducted in the laboratories, many men are unwilling to be tested as a result of social stigma in certain regions of the world. One solution can be found in at-home sperm analysis, which allows men to test their semen without the hassle of going to and paying for a clinic. Herein, we examine current at-home sperm analysis technologies and compare them to the traditional laboratory-based methods. In addition, we discuss emerging sperm analysis approaches and describe their limitations and future directions.

Abstract
The European Rosetta mission has been following comet 67P/Churyumov-Gerasimenko for 2 years, studying the nucleus and coma in great detail. For most of these 2 years the Rosetta Orbiter Sensor for Ion and Neutral Analysis (ROSINA) has analysed the volatile part of the coma. With its high mass resolution and sensitivity it was able to not only detect deuterated water HDO, but also doubly deuterated water, D2O and deuterated hydrogen sulfide HDS. The ratios for [HDO]/[H2O], [D2O]/[HDO] and [HDS]/[H2S] derived from our measurements are (1.05 ± 0.14) × 10-3, (1.80 ± 0.9) × 10-2 and (1.2 ± 0.3) × 10-3, respectively. These results yield a very high ratio of 17 for [D2O]/[HDO] relative to [HDO]/[H2O]. Statistically one would expect just 1/4. Such a high value can be explained by cometary water coming unprocessed from the presolar cloud, where water is formed on grains, leading to high deuterium fractionation. The high [HDS]/[H2S] ratio is compatible with upper limits determined in low-mass star-forming regions and also points to a direct correlation of cometary H2S with presolar grain surface chemistry.This article is part of the themed issue 'Cometary science after Rosetta'.

Abstract
BACKGROUND The scale and variables linked to bariatric surgery's effect on dyslipidemia have not been conclusive. OBJECTIVE To compare the effect of Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and adjustable gastric banding (LAGB) on dyslipidemia SETTING: National bariatric surgery registry. METHODS Plasma lipids and associated variables were compared at baseline and 1 year (12±4 mo) after surgery for registry patients with dyslipidemia enrolled from June 2013 to August 2014. RESULTS The greatest mean total-cholesterol (TC) reduction was observed post-RYGB, 226.7±26.4 to 181.3±30.9 mg/dL (19.9%, n = 208), followed by post-SG, 227.9±24.4 to 206.7±34.2 mg/dL (8.9%, n = 1515; P<.001). Normal TC levels of below 200 mg/dL were achieved by 76% post-RYGB patients compared with 43.5% post-SG patients (odds ratio [OR] = 6.24, 95% confidence interval [CI]: 3.69-10.53) and 25.6% post-LABG patients (OR = 9.66, 95% CI: 4.11-22.67; P<.01). Although equivalent patterns were observed for low-density-lipoprotein cholesterol (LDL), the levels of high-density-lipoprotein cholesterol (HDL) were most improved post-SG, reaching normal levels in 58.1% of SG male patients versus 39.5% of RYGB male patients (OR = 1.56, 95% CI: 1.04-2.35), (P = .02). The lowering of triglyceride levels by approximately 75% was comparable after SG and RYGB procedures. The type of surgery was the strongest independent predictor for all lipid level improvements or remissions. Male sex was an independent predictor for LDL normalization only (OR = 1.88, 95% CI: 1.24-2.85). Excess weight loss offered no meaningful prediction for lipid improvement (OR = 1.01-1.03). CONCLUSION Particular types of bariatric surgeries had different effects on dyslipidemia, independent of weight loss. Overall, the RYGB achieved the biggest reduction in plasma lipids (TC and LDL), although SG did affect HDL. Our results could aid in the decision-making process regarding the most appropriate procedure for patients with dyslipidemia.

Abstract
AIM To investigate the frequency of sonographic findings that required neurosurgical consultation for all referred outpatients suspected to have benign macrocrania (BMC). MATERIALS AND METHODS A retrospective review was performed from September 2011 until June 2015 for all outpatients referred to the ultrasound (US) department for BMC. Electronic medical records, US images, and reports were reviewed in conjunction with follow-up imaging. Each review consisted of gender, specialty of referring physician, first head circumference, head circumference at or closest to the time of the head US, the last head circumference, and any neurological issue prior to the US, at the time of US, or following the US, and clinical outcomes. Statistical analysis employed the Kruskal-Wallis rank sum test and Fischer's exact test (chi square test of independence) that compared normal/BMC patients from the patients requiring a neurosurgical consultation. RESULTS One hundred and thirty (40.9%) had a normal head US, 181 patients (56.9%) had sonographic findings of BMC, and seven (2.2%) patients had an abnormal head US that required a neurosurgical consultation. Of the 181 patients with BMC, 23 underwent follow-up imaging with 22 patients having unchanged BMC or a normal head US and one patient developing mild ventriculomegaly that was stable on follow-up imaging. Three of the seven patients (1%) aged 1.8, 2.3, and 13.1 months with abnormal head US requiring neurosurgical consultation, had mild ventriculomegaly that was stable on follow-up imaging. Four of the seven patients (1.2%) that required neurosurgical consultation needed a neurosurgical procedure. Between the two US subgroups (normal and BMC), no statistical significance was noted regarding age of patient at US, head circumference at clinical and radiological presentation (p>0.05) except for the first head circumference clinically documented which demonstrated statistical significance (p<0.03). CONCLUSION Short interval surveillance including head circumference and assessment for the development of bulging anterior fontanelle and neurological abnormalities may be more cost effective than US in the initial evaluation of patients clinically suspected to have BMC.

Abstract
BACKGROUND Although laparoscopic sleeve gastrectomy (LSG) has been shown to have a long-term antidiabetic effect, little is known regarding the immediate response to surgery. This study's objective was to evaluate the glycemic and lipid metabolic response in the first postoperative week. METHODS The study included 21 obese diabetic participants. Glycemic markers, lipids, and hepatic function tests were measured just prior to surgery and at 1 week and 3 months postoperatively. Two participants were dropped prior to all measurements due to technical reasons, and two more were lost to follow-up. RESULTS At 1 week after surgery, compared to preoperative baseline, we found reduced hemoglobin A1c (7.63 to 7.31, P < 0.001), insulin (24.96 to 10.92, P < 0.05), and borderline significant homeostatic model assessment insulin resistance (HOMA-IR, 9.48 to 3.91, P > 0.05). Low-density lipoprotein (LDL) cholesterol increased and high-density lipoprotein (HDL) cholesterol decreased. Three months after surgery, hemoglobin A1c, insulin, and HOMA-IR continued to decrease (6.05, 7.11, and 1.92, respectively, P < 0.05), with hemoglobin A1c correlated to weight loss (P < 0.05). Triglycerides, triglyceride to HDL ratio, and total cholesterol to HDL ratio also decreased, but there was no significant change in LDL cholesterol or HDL versus presurgery levels. Reduced triglyceride levels were correlated with reduced alanine transaminase (ALT) and gamma-glutamyl transpeptidase (GGT) (P < 0.05). CONCLUSIONS LSG is associated with marked antidiabetic effects as early as 1 week after surgery, unrelated to weight loss. The antidiabetic effect improves at 3 months. Triglyceride reduction was associated with improved hepatic functions, but cholesterol did not show a meaningful reduction.

Abstract
Observations of the green and red-doublet emission lines have previously been realized for several comets. We present here a chemistry-emission coupled model to study the production and loss mechanisms of the O(1S) and O(1D) states, which are responsible for the emission lines of interest for comet 67P/Churyumov-Gerasimenko. The recent discovery of O2 in significant abundance relative to water 3.80 ± 0.85% within the coma of 67P has been taken into consideration for the first time in such models. We evaluate the effect of the presence of O2 on the green to red-doublet emission intensity ratio, which is traditionally used to assess the CO2 abundance within cometary atmospheres. Model simulations, solving the continuity equation with transport, show that not taking O2 into account leads to an underestimation of the CO2 abundance within 67P, with a relative error of about 25%. This strongly suggests that the green to red-doublet emission intensity ratio alone is not a proper tool for determining the CO2 abundance, as previously suggested. Indeed, there is no compelling reason why O2 would not be a common cometary volatile, making revision of earlier assessments regarding the CO2 abundance in cometary atmospheres necessary. The large uncertainties of the CO2 photodissociation cross section imply that more studies are required in order to better constrain the O(1S) and O(1D) production through this mechanism. Space weather phenomena, such as powerful solar flares, could be used as tools for doing so, providing additional information on a good estimation of the O2 abundance within cometary atmospheres.

Abstract
AIM: To evaluate a new imaging device for colonoscopy that adds two side viewing CMOS lenses, the Third Eye® Panoramic™ cap.
METHODS: In this prospective observational feasibility study, 33 patients, 18 male and 15 female, underwent routine screening, surveillance or diagnostic colonoscopy with the new Third Eye® Panoramic™ cap clipped on to the distal tip of a high definition Fuji EC530-LS Slim Colonoscope®. All procedures were performed at the New York Presbyterian-Queens Endoscopy unit by two experienced endoscopists (Rubin M and Kim SH). Main outcome measurements included evaluation of the image quality of the Third Eye® Panoramic™ cap, adenoma detection rate, cecal intubation rate, withdrawal time and total procedure time.
RESULTS: The Third Eye® Panoramic™ cap enabled enhanced views without affecting the quality of the colonoscope’s image or its handling characteristics through the colon. Ileal intubation was accomplished in most cases, but was more challenging. The side view lenses detected polyps and diverticula hidden behind folds and in flexures not seen on the standard view. The side view lenses were easily cleaned utilizing an Endogator® Irrigation Pump (Medivators, Minneapolis, MN, United States) by angling the scope tip against the mucosa while washing. The cecum was reached in all 33 patients. Mean cecal intubation time was 8.19 ± 2.17 min, mean withdrawal time was 10.15 ± 5.56 min and mean total procedure time was 20.31 ± 5.14 min. The overall adenoma detection rate was 44%.
CONCLUSION: The Third Eye® Panoramic™ cap enables wide view colonoscopy with enhanced visualization utilizing standard forward view colonoscopes.

Abstract
Molecular nitrogen (N2) is thought to have been the most abundant form of nitrogen in the protosolar nebula. It is the main N-bearing molecule in the atmospheres of Pluto and Triton and probably the main nitrogen reservoir from which the giant planets formed. Yet in comets, often considered the most primitive bodies in the solar system, N2 has not been detected. Here we report the direct in situ measurement of N2 in the Jupiter family comet 67P/Churyumov-Gerasimenko, made by the Rosetta Orbiter Spectrometer for Ion and Neutral Analysis mass spectrometer aboard the Rosetta spacecraft. A N2/CO ratio of (5.70 ± 0.66) × 10(-3) (2σ standard deviation of the sampled mean) corresponds to depletion by a factor of ~25.4 ± 8.9 as compared to the protosolar value. This depletion suggests that cometary grains formed at low-temperature conditions below ~30 kelvin.

Abstract
Comets contain the best-preserved material from the beginning of our planetary system. Their nuclei and comae composition reveal clues about physical and chemical conditions during the early solar system when comets formed. ROSINA (Rosetta Orbiter Spectrometer for Ion and Neutral Analysis) onboard the Rosetta spacecraft has measured the coma composition of comet 67P/Churyumov-Gerasimenko with well-sampled time resolution per rotation. Measurements were made over many comet rotation periods and a wide range of latitudes. These measurements show large fluctuations in composition in a heterogeneous coma that has diurnal and possibly seasonal variations in the major outgassing species: water, carbon monoxide, and carbon dioxide. These results indicate a complex coma-nucleus relationship where seasonal variations may be driven by temperature differences just below the comet surface.

Abstract
BACKGROUND The incidence, recurrence, and all-cause mortality rate for Clostridium difficile-associated diarrhea (CDAD) has increased markedly over the past 10 years despite treatment. Low vitamin D levels are known to impair immune responses to infection and are associated with increased mortality. We compared the role of patient comorbidity measured by the Charlson Comorbidity Index (CCI) with vitamin D levels to ascertain whether vitamin D levels were an independent variable affecting the outcome of CDAD or a marker of overall comorbidity. METHODS A prospective cohort study studied 62 patients hospitalized between 2008 and 2009 with manifestations of CDAD and a positive C. difficile toxin assay. All patients received standard antibiotics (metronidazole and/or vancomycin). Their status at 30-day follow up was classified as resolved or recurred/expired. Patients' CCI was calculated using their medical history. Logistic regression analysis of variables including 25-hydroxyvitamin D, CCI, age, gender, white blood cell count (WBC), albumin and residence type were performed. RESULTS There were 62 patients (43.6% men, 56.4% women) with CDAD; mean age was 75 ± 17 years. At 30-day follow up, 28 (45.2%) expired, 10 (16.1%) had persistent or recurrent diarrhea and 24 (38.7%) resolved. Nonresolution was seen in 38 (61.3%). There was no significant association between 30-day resolution status and CCI, gender, WBC, albumin level or residence type. Two variables were found to be independent predictors of resolution of CDAD: normal vitamin D levels (p = 0.028) and age <70 years (p = 0.024). Subjects with low vitamin D were 4.75 times more likely to fail to resolve CDAD than subjects with normal Vitamin D. CONCLUSION In this study, vitamin D level and age are independent predictors of CDAD resolution in hospitalized patients. Low vitamin D levels and age >70 years old are associated with increased likelihood of recurrence. Low vitamin D levels are not a marker of comorbidity or advanced age.

Abstract
BACKGROUND Upper gastrointestinal bleeding (UGIB) accounts for 400,000 hospital admissions in the US each year. Despite advances, mortality rates remain high and are estimated to be 5-10%. Early therapeutic endoscopy is widely recommended as a means of reducing morbidity and mortality. The Rockall and Blatchford scores are clinical scoring systems devised to assist in risk stratifying patients with UGIB. In a prior study we found that rapid live bedside video capsule endoscopy (VCE) utilizing Pillcam ESO(®) correctly identified patients with high-risk stigmata of bleeding seen on upper endoscopy. In this study, we compare the accuracy of the Rockall and Blatchford scores with Pillcam ESO(®) in predicting high-risk endoscopic stigmata. METHODS Pre-endoscopy Blatchford and Rockall scores were calculated for 25 patients (14 males, 11 females) presenting to the emergency room with acute UGIB. The average patient was 66 years of age. A total of 24 out of 25 patients underwent upper endoscopy within 24 hours. One patient did not undergo endoscopy due to clinical instability. The timing of endoscopy was based on clinical parameters in 12 patients, and on live view VCE with Pillcam ESO(®) in the other 13 patients. Positive VCE was defined as red blood, clot or coffee grounds. Mean Rockall and Blatchford scores for all 24 patients were compared to determine potential differences between high- and low-risk patients. Rockall and Blatchford scores were also compared with VCE findings. RESULTS Of 24 patients, 13 had high-risk stigmata on upper endoscopy. The mean Rockall and Blatchford scores were 3 and 13, respectively. In the 11 patients without stigmata, the mean Rockall and Blatchford scores were 2 and 11, respectively. There was no statistically significant difference between the Blatchford scores of the two groups (95% confidence interval [CI] -5.1 to 1.3; p = 0.22). There was no statistically significant difference between the Rockall scores of the two groups (95% CI -2.3 to 0.3; p = 0.11). In the subgroup of 12 patients who underwent VCE prior to endoscopy, 8/12 had positive findings, which were all confirmed at endoscopy. All 4 patients with negative VCE had no high-risk stigmata at endoscopy. CONCLUSION In emergency room patients with acute UGIB, neither the Rockall nor the Blatchford scores were able to differentiate high- and low-risk patients identified at endoscopy. Live view VCE, however, was accurate in predicting high-risk endoscopic stigmata, and may be better suited as a risk stratification tool. Additional studies with a larger cohort will be required to validate these findings.

Abstract
AIM: To determine the test characteristics of community based video capsule endoscopy (VCE) in patients undergoing sequential VCE and double balloon enteroscopy (DBE).
METHODS: Eighty-nine patients (34 females, 55 males, mean age 66) who underwent both VCE and DBE from 2008-2010 were retrospectively reviewed. Lesions detected at VCE were categorized. Capsule directed DBE followed and included 44 antegrade, 11 retrograde and 34 combined antegrade and retrograde procedures. Lesions detected were compared utilizing the McNemar’s test.
RESULTS: Angioectasia detection with VCE was 25% and with DBE 35% (P < 0.03) with a calculated sensitivity and specificity of 58% and 93% respectively. Polyps were detected by VCE in 22% and in DBE 20%, (P = 0.6), with a sensitivity and specificity for VCE of 61% and 87%. Small bowel diverticula were only seen in 1% of VCE but in 12% of DBE patients (P < 0.002) with a calculated sensitivity and specificity of VCE of 9% and 100%.
CONCLUSION: VCE would be moderately sensitive and specific overall with considerable variation by lesion. Furthermore, VCE cannot be relied upon to diagnose small bowel diverticula.

Abstract
BACKGROUND Obesity is associated with a poor anesthetic risk, in part because of the greater aspiration rates. A greater gastric residue and lower stomach pH have been implicated. The relationship of obesity to gastric emptying is ill-defined. with contradicting reports stating shorter, similar, and longer times compared with nonobese subjects. The aim of the present study was to compare gastric emptying in obese and nonobese subjects at a university hospital. METHODS A total of 19 obese (body mass index [BMI] >40 kg/m(2)) and 20 nonobese (BMI <30 kg/m(2)) subjects underwent a standardized scintigraphic gastric emptying study. The participants consumed a standard semisolid, technetium-99m-labeled meal. Images were acquired immediately and 1, 2, and 4 hours after meal completion. The interval to evacuate one half of the counts measured at meal completion) and retention (the percentage of counts in stomach at each measurement point) were recorded. RESULTS The mean age and BMI was 35 years and 45 kg/m(2) in the obese and 44 years and 26 kg/m(2) in the nonobese group, respectively. No differences were found between the 2 groups regarding gastric emptying. Regression analysis showed no statistical association between the BMI and gastric emptying, including multivariate analysis, considering BMI, age, and gender. CONCLUSION A scintigraphy test of a labeled meal was used to evaluate gastric emptying in obese and nonobese subjects. In accordance with other published data, no significant difference was found between the 2 groups. The anesthetic risks in the obese should be attributed to factors other than delayed gastric emptying (i.e., anatomic variation, increased rates of hiatal hernia and reflux).

Abstract
Background The life expectancy of patients with HIV has increased significantly since the introduction of highly active antiretroviral therapy in 1995. Although this population of patients now carries less risk for the development of AIDS defining illnesses and malignancies, they are still at risk for non-AIDS defining cancers, such as colon, prostate, and breast. Several studies have shown that HIV infected patients have a higher prevalence of advanced colonic neoplasia which occur at a younger age. Our aim is to examine the prevalence of adenomas and adenocarcinoma in HIV patients undergoing colonoscopy. Methods HIV patients seen in our gastroenterology clinic and inpatient service undergoing colonoscopy were identified from 2010 - 2011. Indication was screening in 27 patients and diagnostic in 23 patients. Significant lesions were defined as adenomas, serrated polyps, and adenocarcinoma. Results Total 50 patients were included in the study, 32 male and 18 female (mean age: 53.6; range 37 - 72 years), 25 patients were African American, 21 were Hispanic, 3 were Caucasian, and one was Indian, 39 patients had undetectable HIV RNA, 30 patients had CD4 lymphocyte counts greater than 500, 20 had CD4 lymphocyte counts less than 500, and 4 patients had CD4 lymphocyte counts less than 200, 52% (26/50) of patients had polyps. Significant lesions (adenomas and serrated polyps) were seen in 34% (17/50) of patients, 39% in diagnostic and 30% in screening procedures (P = 0.56). Males were found to have significant lesions 28% of the time as compared to 44% of females (P = 0.35), 43% of Hispanics had significant lesions versus 24% of African Americans (P = 0.22), 25% of the patients under age 50 were found to have significant lesions, 45% of the patients with detectable HIV RNA levels were found to have significant lesions vs 31% (P = 0.48). Surprisingly, patients with CD4 counts > 500 had significantly more adenomas than those with CD4 counts < 500, 47% vs 15% (P = 0.03). No adenocarcinomas were seen in our patient population. Conclusion In our case series of HIV patients the adenoma detection rate was 34% overall, 45% in the patients with detectable HIV RNA levels, and 47% in patients with CD4 counts > 500. Additionally, there was a 25% adenoma detection rate in patients less than fifty years of age. This data reinforces the need for aggressive colon cancer screening in the HIV population.

Abstract
This paper describes a technique to significantly improve upon the mass peak shape and mass resolution of spaceborne quadrupole mass spectrometers (QMSs) through higher order auxiliary excitation of the quadrupole field. Using a novel multiresonant tank circuit, additional frequency components can be used to drive modulating voltages on the quadrupole rods in a practical manner, suitable for both improved commercial applications and spaceflight instruments. Auxiliary excitation at frequencies near twice that of the fundamental quadrupole RF frequency provides the advantages of previously studied parametric excitation techniques, but with the added benefit of increased sensed excitation amplitude dynamic range and the ability to operate voltage scan lines through the center of upper stability islands. Using a field programmable gate array, the amplitudes and frequencies of all QMS signals are digitally generated and managed, providing a robust and stable voltage control system. These techniques are experimentally verified through an interface with a commercial Pfeiffer QMG422 quadrupole rod system. When operating through the center of a stability island formed from higher order auxiliary excitation, approximately 50% and 400% improvements in 1% mass resolution and peak stability were measured, respectively, when compared with traditional QMS operation. Although tested with a circular rod system, the presented techniques have the potential to improve the performance of both circular and hyperbolic rod geometry QMS sensors.

Abstract
Our objective was to assess the ability of postoperative electroneuronography (ENoG) and electromyography (EMG) to predict clinical facial function 1 year postoperatively in patients with facial paralysis and an intact facial nerve after cerebellopontine angle surgery. The study was a prospective, nonrandomized, uncontrolled clinical trial on an outpatient basis, at a tertiary care hospital. Primary eligibility criteria include: (1) cerebellopontine angle (CPA) surgery with anatomical preservation of facial nerve, (2) complete facial nerve paralysis; and (3) 1 year follow-up. ENoG and EMG were measured at 1 and 3 months postoperatively, House-Brackmann facial nerve grade at 1 year postoperatively. The Kendall coefficient of rank correlation demonstrated that the 1 and 3 month postoperative ENoG data were significant predictors of ultimate facial nerve outcome. Tracking multiple ENoG examinations in a single patient, over time was of little predictive value. EMG was a poor predictor of facial nerve outcome. In general, patients with delayed facial nerve paralysis had better ultimate facial function than patients with immediate paralysis. Postoperative ENoG, but not EMG was a statistically significant predictor of ultimate facial nerve outcome after CPA surgery. Patients with delayed facial paralysis had better outcomes than those with immediate facial paralysis.

Abstract
Angiosarcomas represent 1–2% of soft tissue sarcomas and most frequently occur in the subcutis. They may affect internal
organs, such as the heart, liver, and spleen, and only rarely do they emerge in the gastrointestinal tract. The association
between angiosarcomas and certain toxic chemical substances or previous external-beam radiation therapy is well
documented.
