Homcology: home chemotherapy delivery in a simultaneous care project for frail advanced cancer patients.

Homcology is a project that represents both an opportunity for patients who may benefit from chemotherapy so far, but present physical and social problems that prevent day-hospital access, and a model of "no-profit" contribution to the Public Health System. Our medical oncology department conducted the project from May 2014 to January 2019. We included frail patients (G-8 < 14), with advanced disease, treated with oral, subcutaneous, or parenteral biological agents, with limitations to day-hospital access, comorbidities, and at least 6-month life expectancy. A multidisciplinary team included three oncologists, four nurses, an anesthetist, a psychologist, and a physiotherapist. Satisfaction was evaluated with FAMCARE scale. A total of 188 patients (median age of 73 years, 38-87) were enrolled. Ninety percent of patients presented with metastatic disease and a median G-8 score of 8.8 (3-13.5). All of them received anticancer treatment and concomitant supportive care; 24 patients received two or more lines of treatment. The median duration of taking care was 175 days (7-1200). A median number of 254 (195-325) nursing and 164 (139-190) medical visits were performed a year, with an average of 1.9 and 1.2 visits a month per patient respectively. The median number of in-line patients was 20 (17-25). Hospitalization occurred in 18% of cases. One-third of them died at home. The others were referred to hospice. Our experience shows that the integration of home cancer treatment and supportive care is effective. Hospitalization rate is lower than data reported in the literature. Results need to be confirmed in prospective pharmacoeconomics studies.

[Psychological processes of stress management and neuroendocrine regulation in incarcerated adolescent offenders: A pilot study]. / Processus psychologiques de gestion du stress et régulation neuroendocrinienne chez les adolescents délinquants en institution fermée : une étude pilote.

BACKGROUND: Adolescence is a stressful period where important biological, psychological and social changes occur. Adolescents are particularly vulnerable during this developmental period and can use various strategies to deal with daily stress, such as substance use or externalizing behaviors. In previous studies, stress in adolescents with externalizing behaviors was often linked to ineffective cognitive coping strategies (i.e., constructive thinking) and overlooking the biological aspects involved in stress management such as neuroendocrine regulation. Indeed, repeated activation of the hypothalamic-pituitary-adrenal (HPA) axis in chronic stress situations may have long-term effects on subsequent cortisol regulation and lead to psychological difficulties. It was also shown that basal cortisol levels are lower in adolescents with externalizing behaviors. This study aims to assess the links between constructive thinking and neuroendocrine regulation in adolescent offenders and their association with externalizing symptoms (e.g., aggression, delinquency, psychopathic traits, substance use). Identifying particular biopsychological patterns can help to better understand stress management in youth with externalizing behaviors and to improve clinical treatments. METHOD: Sixteen adolescent males aged from 12 to 18 years were recruited in an institution for juvenile offenders. Exclusion criteria were insufficient reasoning abilities assessed using the Raven Matrices Test. Regarding psychological dimensions, constructive thinking was assessed through the Constructive thinking inventory (CTI), psychopathic traits through the Youth psychopathic traits inventory (YPI), externalizing behaviors through 30 items (out of 113) and 2 subscales (aggressive behavior and delinquency problems) from the Child behavior checklist-youth self-report (CBCL), and substance use through the Dep-ado. Regarding biological dimensions, cortisol daily secretion and regulation were assessed through saliva samples that were collected during 3 consecutive days (4 samples per day: directly after awakening, at 10 a.m., at 4 a.m., and before going to bed). RESULTS: Adolescent offenders presented maladaptative thinking styles and a particular neuroendocrine regulation in their daily management with stress. In particular, their level of cortisol in the morning was higher than those expected in a general population (20.34 nmol/L while the norm is around 10 nmol/L). They also showed more agressive and delinquent behaviors (CBCL) as well as more psychopathic traits (YPI) than the general population. Moreover, constructive thinking style was associated with personality and behavioral dimensions. Indeed, results indicated positive and significant correlations between categorical thinking style (CTI), psychopathic traits (YPI) (r=0.57, P=0.021) and externalizing behaviors (CBCL) (r=0.55, P=0.028). In other words, the more adolescent offenders used categorical thinking, the more they presented psychopathic traits and externalizing behaviors. With respect to the association between psychological and biological dimensions in stress management, we observed a significant and positive correlation between cortisol regulation and esoteric thinking (r=0.57, P=0.028) and a trend with superstitious thinking (r=0.47, P=0.075). The more adolescent offenders used esoteric and superstitious thinking, the poorer was their cortisol regulation. We also observed a trend between the life style scale of the YPI (i.e., impulsive, irresponsible) and the daily secretion of cortisol (r=0.51; P=0.052) as well as cortisol regulation (r=0.49, P=0.065). The more adolescent offenders presented psychopathic traits, the higher tended to be their daily secretion of cortisol and the poorer their cortisol regulation. Finally, cortisol regulation (r=0.54, P=0.038) and secretion (r=0.73, P=0.002) were significantly correlated with the DEP-Ado score. In other words, a poor cortisol regulation and a high secretion of cortisol seem to be associated with substance use. CONCLUSIONS: Adolescent offenders face an important amount of daily stress and do not always have the appropriate skills to deal with it. Indeed, we know from clinical experience that they often report a sense of hopelessness toward their lack of professional perspectives as well as familial conflicts which can be important stressors in addition to the incarceration in itself. Therefore, treatment aiming to improve psychic elaboration can help these adolescents to make their thinking styles more flexible and use more appropriate ways of coping with stress instead of externalizing behaviors and substance use. Moreover, considering the complex cases of these adolescents and the many changes of caregivers and institutions where they have lived, which can be important stressors as well, professionals working with these youth should be aware of their emotional reactions toward them and try to encourage continuity of care.

Environmental justice burden and Black-White disparities in spontaneous preterm birth in Harris County, Texas.

Introduction: Given limited evidence of previous studies, we evaluated the role of environmental justice (EJ) burden (i.e., a neighborhood characterized by both increased environmental burden and socioeconomic deprivation) in Black-White disparities in spontaneous preterm birth (sPTB) in Harris County, Texas and compared results that evaluated neighborhood-level socioeconomic deprivation alone. Methods: We conducted a retrospective analysis using PeriBank, a database and biospecimen repository of gravidae giving birth at two hospitals in the Texas Medical Center. We included 3,703 non-Hispanic Black and 5,475 non-Hispanic white gravidae who were U.S.-born, delivered from August 2011-December 2020, and resided in Harris County, TX. We used data from the U.S. EPA EJScreen to characterize the EJ burden of participant's zip code of residence from fine particulate matter (PM2.5), ozone, and proximity to National Priorities List (NPL) sites and calculated zip-code level Area Deprivation Index (ADI). We assessed the contribution of neighborhood-level variables to the Black-White disparity in sPTB by evaluating attenuation of the odds ratio (OR) representing the effect of race in multivariable logistic regression models, controlling for individual-level characteristics. We also conducted race-stratified analyses between each neighborhood variable and sPTB. Exposure indices were treated as continuous variables; in stratified models, ORs and 95% Confidence Intervals (CIs) are presented per 10-unit increase in the neighborhood variable. Results: Accounting for individual-level variables, Black gravidae had 79% higher odds of sPTB than white gravidae (OR = 1.79, 95%CI = 1.32, 2.44); the disparity was moderately attenuated when accounting for EJ burden or ADI (ORs ranged from 1.58 to 1.69). Though we observed no association between any of the EJ burden indices and sPTB among white gravidae, we found increased risks among Black gravidae, with ORs of similar magnitude for each EJ variable. For example, Black gravidae experienced 17% increased odds of sPTB associated with a 10-unit increase in the EJ burden index for PM2.5 (OR = 1.17, 95%CI = 0.97, 1.40). No racial differences were observed in the association of ADI with sPTB. Discussion: Though we observed limited evidence of the contribution of living in EJ neighborhoods to the Black-White disparity in sPTB, our study suggests living in an EJ neighborhood may differentially impact Black and white gravidae.

[The influence of colostral antibodies on the postvaccination humoral immune response in neonatal calves]. / Einfluss kolostraler Antikörper auf die Postvakzinale Humorale Immunantwort bei Neonatalen Kälbern.

The aim of this study was to evaluate the efficiency of vaccination of young calves and to see whether maternal antibodies may influence the immunological response in calves. For this project 20 matched-pairs of cows and their offspring were selected. Of each pair, one cow received a placebo 8 and 4 weeks before term (group A) and the other was vaccinated against Feline Leucose Virus, FeLV, with Leucogen® (group B). All calves received colostrum from their respective mother shortly after birth and all calves were vaccinated with Leucogen® 10 days after birth. Blood samples from the cows and calves were taken during the whole study period (till four weeks after calf vaccination). An ELISA test was done in the lab to define the FeLV antibody concentration. 30 % of the vaccinated cows showed a seroconversion, 13 out of 20 vaccinated cows passed the antibodies onto their calves. 11 calves of group B did not convert in comparation of only 4 of group A. All seroconverted calves had low antibody concentration before their vaccination. Calves of group B with a low passive antibody level at the beginning showed a higher seroconversion as compared to calves with higher antibody concentrations of the same group. Two thirds of the calves without maternal antibodies reacted adequately to the vaccination. Therefore, an early vaccination of calves can be recommended.

Optical coherence tomography.

Optical coherence tomography (OCT) is a non-contact method for imaging the topological and internal microstructure of samples in three dimensions. OCT can be configured as a conventional microscope, as an ophthalmic scanner, or using endoscopes and small diameter catheters for accessing internal biological organs. In this Primer, we describe the principles underpinning the different instrument configurations that are tailored to distinct imaging applications and explain the origin of signal, based on light scattering and propagation. Although OCT has been used for imaging inanimate objects, we focus our discussion on biological and medical imaging. We examine the signal processing methods and algorithms that make OCT exquisitely sensitive to reflections as weak as just a few photons and that reveal functional information in addition to structure. Image processing, display and interpretation, which are all critical for effective biomedical imaging, are discussed in the context of specific applications. Finally, we consider image artifacts and limitations that commonly arise and reflect on future advances and opportunities.

Dendritic cells directly trigger NK cell functions: cross-talk relevant in innate anti-tumor immune responses in vivo.

Cytotoxic T lymphocytes and natural killer cells are essential effectors of anti-tumor immune responses in vivo. Dendritic cells (DC) 'prime' tumor antigen-specific cytotoxic T lymphocytes; thus, we investigated whether DC might also trigger the innate, NK cell-mediated anti-tumor immunity. In mice with MHC class I-negative tumors, adoptively transferred- or Flt3 ligand-expanded DC promoted NK cell-dependent anti-tumor effects. In vitro studies demonstrated a cell-to-cell contact between DC and resting NK cells that resulted in a substantial increase in both NK cell cytolytic activity and IFN-gamma production. Thus, DC are involved in the interaction between innate and adaptive immune responses.

[New guidelines for bariatric surgery care: practical implications]. / Nouvelles directives assécurologiques pour la prise en charge de la chirurgie bariatrique: conséquences pratiques.

From the 1st of January 2011, new conditions have been validated in which surgery for weight loss is borne by the basic insurance. These are very significant changes compared to the old criteria. Indeed, on one hand, patients with BMI > or = 35 kg/m2 may, without age limit and in the absence of comorbidities benefit from surgery without prior request to the medical council health insurance company concerned. On the other hand, the notion of a minimum casuistry is for the first time introduced in centers performing this type of intervention. In addition, certified centers are required to follow standard procedures for the patients' teaching and follow up.

Co-registered spectrally encoded confocal microscopy and optical frequency domain imaging system.

Spectrally encoded confocal microscopy and optical frequency domain imaging are two non-contact optical imaging technologies that provide images of tissue cellular and architectural morphology, which are both used for histopathological diagnosis. Although spectrally encoded confocal microscopy has better transverse resolution than optical frequency domain imaging, optical frequency domain imaging can penetrate deeper into tissues, which potentially enables the visualization of different morphologic features. We have developed a co-registered spectrally encoded confocal microscopy and optical frequency domain imaging system and have obtained preliminary images from human oesophageal biopsy samples to compare the capabilities of these imaging techniques for diagnosing oesophageal pathology.

Selective effects of PPARgamma agonists and antagonists on human pre-adipocyte differentiation.

AIM: The insulin sensitizer rosiglitazone (RTZ) acts by activating peroxisome proliferator and activated receptor gamma (PPAR gamma), an effect accompanied in vivo in humans by an increase in fat storage. We hypothesized that this effect concerns PPARgamma(1) and PPARgamma(2) differently and is dependant on the origin of the adipose cells (subcutaneous or visceral). To this aim, the effect of RTZ, the PPARgamma antagonist GW9662 and lentiviral vectors expressing interfering RNA were evaluated on human pre-adipocyte models. METHODS: Two models were investigated: the human pre-adipose cell line Chub-S7 and primary pre-adipocytes derived from subcutaneous and visceral biopsies of adipose tissue (AT) obtained from obese patients. Cells were used to perform oil-red O staining, gene expression measurements and lentiviral infections. RESULTS: In both models, RTZ was found to stimulate the differentiation of pre-adipocytes into mature cells. This was accompanied by significant increases in both the PPARgamma(1) and PPARgamma(2) gene expression, with a relatively stronger stimulation of PPARgamma(2). In contrast, RTZ failed to stimulate differentiation processes when cells were incubated in the presence of GW9662. This effect was similar to the effect observed using interfering RNA against PPARgamma(2). It was accompanied by an abrogation of the RTZ-induced PPARgamma(2) gene expression, whereas the level of PPARgamma(1) was not affected. CONCLUSIONS: Both the GW9662 treatment and interfering RNA against PPARgamma(2) are able to abrogate RTZ-induced differentiation without a significant change of PPARgamma(1) gene expression. These results are consistent with previous results obtained in animal models and suggest that in humans PPARgamma(2) may also be the key isoform involved in fat storage.

Weight Loss Directly Influences Intermediate-Term Remission of Diabetes Mellitus After Bariatric Surgery: A Retrospective Case-Control Study.

PURPOSE: Roux en Y gastric bypass surgery (RYGB) is an effective therapy for patients with severe obesity. It induces both significant weight loss and rapid improvements of metabolic complications. This study was undertaken to better define the direct role of weight loss in the metabolic improvements. METHODS: A retrospective, case-control study of a cohort of 649 patients with obesity who underwent RYGB, comparing higher and lower responders at 2 years after surgery (n = 100 pairs). Pairs of patients were matched for age, gender, and initial BMI. The rates of remission of diabetes, hypertension, dyslipidemia, and hyperuricemia were compared using a mixed effects logistic regression analysis. RESULTS: Diabetes before surgery was present in 12/100 lower responders and 17/100 higher responders. Remission at 2 years was observed in 4/12 (33%) of lower responders, compared to 15/17 (88%) of higher responders. Thus, the odds of diabetes remission was significantly smaller in lower responders (OR = 0.067, 95% CI 0.01-0.447). A mixed model regression analysis of all the parameters for each patient showed that the odds of achieving remission of any comorbidity was significantly lower in lower responders (OR = 0.62, 95% CI = 0.39-0.97). CONCLUSION: We could demonstrate that weight loss is a significant determinant of the remission of diabetes 2 years after RYGB. These data underline the importance of weight loss in the benefits of this procedure.

A new type of internal hernia after laparoscopic Roux-en-Y gastric bypass.

Roux-en-Y gastric bypass (RYGBP) is currently the most common bariatric procedure. One of its late complications is the development of internal hernia, which can lead to acute intestinal obstruction or recurrent colicky abdominal pain. The aim of this paper is to present a new, unusual, and so far not reported type of internal hernia. A common computerized database is maintained for all patients undergoing bariatric surgery in our departments. The charts of patients with the diagnosis of internal hernia were reviewed. Three patients were identified who developed acute intestinal obstruction due to an internal hernia located between the jejunojejunostomy and the end of the biliopancreatic limb, directly between two jejunal limbs with no mesentery involved. Another seven patients with intermittent colicky abdominal pain, re-explored for the suspicion of internal hernia, were found to also have an open window of the same location apart from a hernia at one of the typical hernia sites. Since this gap is systematically closed during RYGBP, no other patient has been observed with this problem. Even very small defects can lead to the development of internal hernias after RYGBP. Patients with suggestive symptoms must be explored. Closure of the jejunojejunal defect with nonabsorbable sutures prevents the development of an internal hernia between the jejunal loops at the jejunojejunostomy.

A central role for the armadillo protein plakoglobin in the autoimmune disease pemphigus vulgaris.

In pemphigus vulgaris (PV), autoantibody binding to desmoglein (Dsg) 3 induces loss of intercellular adhesion in skin and mucous membranes. Two hypotheses are currently favored to explain the underlying molecular mechanisms: (a) disruption of adhesion through steric hindrance, and (b) interference of desmosomal cadherin-bound antibody with intracellular events, which we speculated to involve plakoglobin. To investigate the second hypothesis we established keratinocyte cultures from plakoglobin knockout (PG-/-) embryos and PG+/+ control mice. Although both cell types exhibited desmosomal cadherin-mediated adhesion during calcium-induced differentiation and bound PV immunoglobin (IgG) at their cell surface, only PG+/+ keratinocytes responded with keratin retraction and loss of adhesion. When full-length plakoglobin was reintroduced into PG-/- cells, responsiveness to PV IgG was restored. Moreover, in these cells like in PG+/+ keratinocytes, PV IgG binding severely affected the linear distribution of plakoglobin at the plasma membrane. Taken together, the establishment of an in vitro model using PG+/+ and PG-/- keratinocytes allowed us (a) to exclude the steric hindrance only hypothesis, and (b) to demonstrate for the first time that plakoglobin plays a central role in PV, a finding that will provide a novel direction for investigations of the molecular mechanisms leading to PV, and on the function of plakoglobin in differentiating keratinocytes.

Earthquake dating: an application of carbon-14 atom counting.

Milligram-sized specimens of detrital charcoal from soil layers associated with prehistoric earthquakes on the Wasatch fault in Utah have been dated by direct atom counting of carbon-14 with a tandem Van de Graaff accelerator. The measured ratios of carbon-14 to carbon-12 correspond to ages of 7800, 8800, and 9000 years with uncertainties of +/- 600 years.

Control of early viral and bacterial distribution and disease by natural antibodies.

Natural antibodies are often dismissed from immunological analysis as "background," but they may play an important role in conferring immunity against infections. In antibody-free mice infected with various viruses or with Listeria monocytogenes, viral or bacterial titers in peripheral organs, including the kidney and brain, were 10 to 100 times greater than in antibody-competent mice (and enhanced their susceptibility to some infections), and titers in secondary lymphoid organs were 10 to 100 times lower than in antibody-competent mice. Thus, natural antibodies play a crucial role by preventing pathogen dissemination to vital organs and by improving immunogenicity through enhanced antigen-trapping in secondary lymphoid organs.

Contribution of thickened drinks, food and enteral and parenteral fluids to fluid intake in hospitalised patients with dysphagia.

BACKGROUND: Studies amongst older people with acute dysphagic stroke requiring thickened fluids have assessed fluid intakes from combinations of beverage, food, enteral and parenteral sources, but not all sources simultaneously. The present study aimed to comprehensively assess total water intake from food, beverages, enteral and parenteral sources amongst dysphagic adult in-patients receiving thickened fluids. METHODS: Patients requiring thickened fluid following dysphagia diagnosis were recruited consecutively from a tertiary teaching hospital's medical and neurosurgical wards. Fluid intake from food and beverages was assessed by wastage, direct observation and quantified from enteral and parenteral sources through clinical medical records. RESULTS: No patients achieved their calculated fluid requirements unless enteral or parenteral fluids were received. The mean daily fluid intake from food was greater than from beverages whether receiving diet alone (food: 807 +/- 363 mL, food and beverages: 370 +/- 179 mL; P < 0.001) or diet with enteral or parenteral fluid support (food: 455 +/- 408 mL, food and beverages: 263 +/- 232 mL; P < 0.001). Greater daily fluid intakes occurred when receiving enteral and parenteral fluid in addition to oral dietary intake, irrespective of age group, whether assistance was required, diagnosis and whether stage 3 or stage 2 thickened fluids were required (P < 0.05). After enteral and parenteral sources, food provided the most important contribution to daily fluid intakes. CONCLUSIONS: The greatest contribution to oral fluid intake was from food, not beverages. Designing menus and food services that promote and encourage the enjoyment of fluid dense foods, in contrast to thickened beverages, may present an important way to improve fluid intakes of those with dysphagia. Supplemental enteral or parenteral fluid may be necessary to achieve minimum calculated fluid requirements.

[Trends in surgery]. / Chirurgie.

More than the number of real novelties, trends and preliminary results characterise the annual development in surgery. The wealth and diversity of topics to be covered require arbitrary choices, therefore not necessarily complete. The constant development of choledocolithiasis management, dominated by minimal invasive technology, treatments of unusual nature of two frequent proctological conditions, fistulae and haemorrhoids, the increasing importance of metabolic bariatric surgery, as well as the strict rules of effective melanoma treatment, represent as many directions in which the operating procedure, although unseen, continue to gain quality and security.

Can disbudding of calves (one versus four weeks of age) induce chronic pain?

BACKGROUND: Calf disbudding is a welfare-relevant invasive husbandry procedure. While it is widely recognized that disbudding elicits acute pain, its chronic consequences are currently unknown. OBJECTIVES: Primary aim of this study was to investigate whether disbudding leads to chronic pain in calves; secondary aim was to evaluate the influence of age at disbudding (1 week versus 4 weeks). METHODS: Thirty-four Holstein bull calves, enrolled in a prospective, controlled, randomized trial, underwent either early disbudding (ED) or late disbudding (LD) or sham treatment (control) at 1 and 4 weeks of age. Pain scoring and quantitative sensory tests (von Frey filaments and algometry) were performed at regular intervals up to 105 days of life; neurophysiological determination of nociceptive reflex thresholds and conditioned pain modulation (CPM) up to 90 days. Data was analyzed with the Brunner and Langer model followed by post-hoc test, with level of significance set at 0.05. RESULTS: Thirty-one calves completed the data collection. Signs of chronic sensitization were observed in 38% of disbudded calves (4 in ED and 4 in LD). Pain scores (until 105 days) and allodynia scores (until 60 days) were significantly higher while pressure thresholds (until 105 days) were significantly lower in both groups ED and LD compared to control. Late disbudded calves showed impairment of trigeminal CPM. Lower laser-evoked trigeminal reflex thresholds were found in clinically painful calves compared to control. CONCLUSIONS: The sequelae of disbudding can extend beyond the acute post-procedural phase. Chronic trigeminal sensitization, independently from the age at disbudding can affect individual calves.

Almost routine prophylactic cholecystectomy during laparoscopic gastric bypass is safe.

BACKGROUND: Morbidly obese patients are at high risk to develop gallstones, and rapid weight loss after bariatric surgery further enhances this risk. The concept of prophylactic cholecystectomy during gastric bypass has been challenged recently because the risk may be lower than reported earlier and because cholecystectomy during laparoscopic gastric bypass may be more difficult and risky. METHODS: A review of prospectively collected data on 772 patients who underwent laparoscopic primary gastric bypass between January 2000 and August 2007 was performed. The charts of patients operated before 2004 were retrospectively reviewed regarding preoperative echography and histopathological findings. RESULTS: Fifty-eight (7.5%) patients had had previous cholecystectomy. In the remaining patients, echography showed gallstones or sludge in 81 (11.3%). Cholecystectomy was performed at the time of gastric bypass in 665 patients (91.7%). Gallstones were found intraoperatively in 25 patients (3.9%), for a total prevalence of gallstones of 21.2%. The age of patients with gallstones was higher than that of gallstone-free patients (43.5 vs 38.7 years, p<0.0001). Of the removed specimens, 81.8% showed abnormal histologic findings, mainly chronic cholecystitis and cholesterolosis. Cholecystectomy was associated with no procedure-related complication, prolonged duration of surgery by a mean of 19 min (4-45), and had no effect on the duration of hospital stay. Cholecystectomy was deemed too risky in 59 patients (8.3%) who were prescribed a 6-month course of ursodeoxycolic acid. CONCLUSION: Concomitant cholecystectomy can be performed safely in most patients during laparoscopic gastric bypass and does not prolong hospital stay. As such, it is an acceptable form of prophylaxis against stones forming during rapid weight loss. Whether it is superior to chemical prophylaxis remains to be demonstrated in a large prospective randomized study.

Gastric liposarcoma in a patient with severe obesity.

Liposarcoma is the most common soft tissue sarcoma in adults. Predominant locations are the limbs and retroperitoneum. Intra-abdominal liposarcoma represents only 2% of all cases and visceral location is exceptional. Gastric liposarcoma is extremely rare, with fewer than 20 cases reported. The treatment of choice is wide en-bloc surgical resection. If the tumour arises in the area of the cardia, resection involves resection of the proximal stomach as well as the distal oesophagus. Traditional reconstruction with oesophagogastrostomy often leads to troublesome reflux. We report a case of gastric liposarcoma arising in the gastro-oesophageal junction in a severely obese patient.
