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
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.

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
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
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
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
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
AbstractThin films of tin-doped indium oxide are widely used for transparent conductors. One application of ln203:Sn (ITO) is transparent contacts for electrochromic electrodes. Optical design of electrochromic devices requires knowledge of the optical constants for each layer from the near ultraviolet and visible to the mid infrared. Determination of the optical constants of the electrochromic layer cannot be made in isolation; a complete device or at least a half-cell including a layer of ITO is required to change the optical state of the electrochromic material. Measurements on ITO were made using variable-angle spectral ellipsometry, and spectral transmittance and reflectance. A series of structural models were fit to this data. The problem is complicated because of inhomogeneity in the films, variability in the manufacturing process, and sensitivity to environmental conditions. The spectral dependency was modeled by a single Lorentz oscillator and a Drude free-electron component. This data was then used as the basis for a model to extract the optical constants for a tungsten oxide electrochromic film.

Abstract
AbstractSnO2:F is a widely used transparent conductor and commercially available in a multilayer structure as Tech glass. Current applications include photovoltaics, electrochromics and displays. Optical design of these and other applications requires knowledge of the optical constants, in some cases, over the whole solar spectrum. Various optical property measurements were performed including variable angle spectroscopic ellipsometry, and spectral transmittance and reflectance measurements. This material is deposited in several steps and has a fairly complex structure. The measured data were fit to models based on this structure to obtain the optical indices. Atomic force microscopy confirmed the optically modeled surface roughness.

Abstract
Mount St. Helens volcano in southern Washington has erupted many times during the last 4000 years, usually after brief dormant periods. This behavior pattern. suggests that the volcano, last active in 1857, will erupt again-perhaps within the next few decades. Potential volcanic hazards of several kinds should be considered in planning for land use near the volcano.

Abstract
9027 Background: Metastatic melanoma remains resistant to therapy. Anti-angiogenesis agents and m-TOR inhibitors have shown modest activity as single agents. In this multicenter phase II trial, we evaluated the combination of bevacizumab and everolimus in the treatment of patients with metastatic melanoma. Methods: Patients with unresectable metastatic melanoma with ECOG PS 0–2 were eligible. Up to 2 previous treatment regimens were allowed; patients previously treated with angiogenesis or m-TOR inhibitors were excluded. Additional eligibility requirements: adequate organ function, no CNS involvement, standard bevacizumab exclusions. All patients received bevacizumab 15mg/kg IV q 3 weeks, and everolimus 10mg po daily. Patients were evaluated every 6 weeks, and treatment continued until disease progression. Results: Between February 2008 and October 2008, 56 patients were enrolled; the first 31 patients are included in this interim report. The median age was 71 years (range 36 to 89 years); 19 patients (61%) had visceral metastases; 0/1/2 previous regimens, 12/11/8 patients; ECOG PS 0/1/2, 17/11/1. 28 patients (90%) received at least 6 weeks of treatment; 3 patients withdrew prior to 6 weeks (toxicity, 2 patients; intercurrent illness, 1 patient). 1 of 28 evaluable patients (4%) had a PR. However, 19 additional patients (68%) had stable disease (15 of these patients had measurable decrease in tumor size), for a disease control rate of 72%. 14 patients remain on treatment, after treatment durations of 2 - 7.5 months. After a median followup of 5 months, the median progression-free survival is 3.5 months (95% CI 2.4 - 5.4 months). Bevacizumab/everolimus was generally well tolerated. 1 patient withdrew because of interstitial pneumonitis (reversible) and 1 patient had a fatal MI, possibly bevacizumab-related. Grade 3 mucositis occurred in 13%; other grade 3 toxicities occurred in < 10% of patients. Conclusions: The combination of bevacizumab and everolimus was well tolerated and has activity in patients with metastatic melanoma. Updated results in all 56 patients will be presented.

Abstract
6012 Background: Concurrent chemotherapy/RT is the standard of treatment for locally advanced head and neck cancer. Agents targeting EGFR and the angiogenesis pathway have also demonstrated activity. In this phase II trial, we added bevacizumab and erlotinib to an active combined modality regimen in the first-line treatment of pts with locally advanced head and neck cancer. Methods: Eligible pts had previously untreated squamous carcinoma of any head and neck site, with T3/T4 primary lesions and/or N1-N3 nodal involvement. Additional eligibility: ECOG PS 0 or 1; adequate organ function; indwelling central venous catheter; standard bevacizumab exclusions. All pts received induction therapy with 2 courses of paclitaxel (200mg/m2), carboplatin (AUC 6.0), 5-FU (200mg/m2 per day, 24 hour CI days 1–21), and bevacizumab (15 mg/kg); cycles were repeated at 21-day intervals. Pts then received concurrent RT (68.4 Gy, 1.8 Gy/day), paclitaxel (50 mg/m2 weekly x 6), bevacizumab (15 mg/kg weeks 1 and 4), and erlotinib (150 mg daily x 7 weeks). PFS was the primary endpoint. Results: Between December 2006 and July 2008, 60 pts were enrolled; the first 48 pts are included in this preliminary report. The median age was 56 years; T3/T4 = 9/8; N1/N2/N3 = 13/27/4. 45 pts (94%) completed the 6-week induction therapy, and 41 pts (85%) completed all therapy. After induction therapy, 56% of pts had objective response; 77% had objective response after completion of therapy. After a median follow-up of 16 months, the 18-month progression-free and overall survivals are 85% and 87%, respectively. Grade 3/4 toxicity during induction therapy included neutropenia (46%), neutropenic fever (6%), mucositis (14%), diarrhea (14%), and hand/foot syndrome (11%). Severe local toxicity (mucositis/esophagitis) occurred in 31 patients (76%) during combined modality therapy (56% grade 3/20% grade 4). Conclusions: The addition of bevacizumab and erlotinib to concurrent chemotherapy/RT was feasible, with no unexpected toxicity. After short followup, the regimen appears highly active. Updated results will be presented. [Table: see text]

Abstract #3148
Background: Vinflunine (VFL) is a novel microtubule inhibitor agent of the vinca alkaloid class that inhibits tubulin polymerization without stabilization, resulting in cell cycle arrest in mitosis and apoptosis. Weak tubulin binding at the vinca-binding site accounts for its reduced neurotoxicity. VFL has demonstrated activity in anthracycline and taxane pretreated patients (pts) and in combination with capecitabine. This trial evaluates the activity and safety of VFL monotherapy and in combination with trastuzumab (T) in HER2+ pts as 1st line therapy metastatic breast cancer (MBC).
 Methods: Eligibility: 0 prior regimens for MBC, > 6 mo from adjuvant therapy, RECIST criteria measurable disease, ECOG PS 0-2, adequate organ function, peripheral neuropathy < G2. Treatment: HER2 unspecified: VFL 320 mg/m2 IV q3 wks; FISH HER2+ pts: VFL 280 mg/m2 plus T 6 mg/kg q3 wks. Response evaluations q9 wks; treatment continued until disease progression or toxicity.
 Results: Due to termination of VFL licensing between BMS and Pierre Fabre Medicament, the study closed prematurely with only 31 evaluable pts of a planned 48 pts in each treatment arm of VFL monotherapy or VFL in combination with T. 10 pts received VFL and 21 pts were treated with VFL + T. Median age: 59 yrs (35-78). ECOG PS 0-18 pts, 1-11 pts, 2-2 pts. 48% were ER+. Prior adjuvant anthracyclines and taxanes noted in 17 and 19 pts respectively. 4 pts presented with de novo stage IV disease, all HER2 positive. 45% had 3 or more metastatic disease sites with bone (17 pts), liver (16 pts) and lung (15 pts) predominating. Median of # cycles: 4 (range 1-19). There were 10 PRs (32%), all in VFL + T, and 9 pts (29%) with PD (VFL-4 pts, VFL + T-5pts). SD was reported in 10 pts (32%). 2 pts (7%) were unevaluable, divided equally between the two arms. G3/4 neutropenia occurred in 11 pts (35%); none with fever. G3 nonhematologic toxicity consisted of pain, attributed to treatment in 5 pts (16%) (sites: abdomen-2, chest, back, and infusion site each in 1 pt), and GI toxicity characterized by N/V 3 pts (10%) as well as abdominal pain, diarrhea, constipation, occurring each in 2 pts (6%). There were no G4 events. 10 pts were hospitalized (GI -4 pts, pain 2 pts, pulmonary 2 pts, and other 2 pts). Median PFS was 3.5 months for VFL and 6.6 months for VFL + T. Median overall survival was 9 months for VFL and has not been reached for VFL + T.
 Conclusions: The combination of vinflunine and trastuzumab is active in the first line treatment of MBC, producing a 48% response rate. Adverse events were as expected, manageable and consisted primarily of neutropenia, pain and GI toxicity. This encouraging activity compares favorably with other trastuzumab combination regimens and merits further evaluation.

Abstract
BACKGROUND Recurrent chromosomal rearrangements have not been well characterized in common carcinomas. Using a novel bioinformatics approach, our group recently described a novel gene fusion in PCa. This fusion involves the androgen-regulated gene TMPRSS2 and so far three members of the ETS family of transcription factors already described as rearranged in the Ewing's family of tumors. By analogy, fusion status in prostate cancer may determine clinical outcome and secondary genetic alterations as witnessed in Ewing's tumors. MATERIAL These novel gene fusions occur in the majority of prostate cancers identified by PSA screening and are the driving mechanism for overexpression of the three members of the ETS transcription factor family, either ERG (21q22.3), ETV1 (7p21.2), or ETV4 (17q21). Considering the high incidence of prostate cancer and the high frequency of this gene fusion, the TMPRSS2-ETS gene fusion is the most common genetic aberration so far described in human malignancies. RESULTS So far, this is the only gene rearrangement in any of the most prevalent cancers. As confirmed by other groups, we demonstrated that, within the group of ETS transcription factors, ERG is the most common fusion partner of the ETS genes with TMPRSS2. This gene fusion is considered to be an early event in PCa development. Emerging data suggest that gene fusion PCa demonstrates a distinct clinical course and thus support its use as a diagnostic test and prognostic biomarker. Also similar to the Philadelphia chromosome in chronic myelogenous leukemia (CML), the gene fusion in prostate cancer has potential as an important candidate for the development of targeted therapy.

Abstract
BACKGROUND Bariatric surgery may be complicated by enlargement of the liver, especially of the left lobe, caused by nonalcoholic fatty liver disease often present with morbid obesity. METHODS The effect of a very low carbohydrate diet for 4 weeks before surgery on liver density and volume was assessed in 14 candidates for bariatric surgery. Computed tomography (CT) scans were performed before and at termination of the diet period. RESULTS The CT scans clearly showed a significant increase in mean liver density (p = 0.06) and a decrease in mean liver volume (p = 0.01). The increased mean density of the left lobe was markedly greater than that of the right lobe. CONCLUSIONS The findings show that 4 weeks of a very low carbohydrate diet reduces liver fat content and liver size, particularly of the left lobe. This approach may render bariatric surgery or any foregut operations less difficult in morbidly obese patients and may be a useful treatment for nonalcoholic fatty liver disease.
