Abstract
Obesity is associated with serious comorbidities and economic implications. Bariatric surgery, most commonly Roux-en-Y gastric bypass and sleeve gastrectomy, are effective options for weight loss and the improvement of obesity-related comorbidities. With the growing obesity epidemic, there has been a concomitant rise in bariatric surgeries, particularly in sleeve gastrectomy, which has been the most widely performed bariatric surgery since 2013. Gastroesophageal reflux disease (GERD) is highly prevalent in obese individuals, can significantly impact quality of life and may lead to serious complications. Obesity and GERD both improve with weight loss. However, as the incidence of sleeve gastrectomy rises, recent data have revealed a risk of exacerbation of pre-existing GERD or the development of de novo GERD following sleeve gastrectomy. We performed a detailed review of GERD post-sleeve gastrectomy, including its overall incidence, pathophysiology and current treatment paradigms.

Abstract
The healthy eating plate concept has been introduced in many countries, including Malaysia, as a visual guide for the public to eat healthily. The relationship between Malaysian Healthy Plate (MHP) and adequate fruit and vegetable (FV) intake among morbid Malaysian adults is unknown. Hence, we investigated the relationship between awareness of the MHP and FV intake among morbid Malaysian adults. National survey data on 9760 morbid Malaysian adults aged 18 years and above were analyzed. The relationship between awareness of MHP and FV intake among Malaysian adults with obesity, diabetes mellitus, hypertension, and hypercholesterolemia were determined using multivariable logistic regression controlling for sociodemographic characteristics and lifestyle risk factors. Our data demonstrated that MHP awareness is associated with adequate FV intake among the Malaysian adults with abdominal obesity (adjusted odds ratio (aOR): 1.86, 95% confidence interval (CI): 1.05-3.29), diabetes mellitus (aOR: 4.88, 95% CI: 2.13-22.18), hypertension (aOR: 4.39, 95% CI: 1.96-9.83), and hypercholesterolemia (aOR: 4.16, 95% CI: 1.48-11.72). Our findings indicated the necessity for ongoing efforts by policymakers, healthcare professionals, and nutrition educators to promote the concept of MHP and ensure that morbid Malaysian adults consume a sufficient intake of FV or adopt a healthy eating pattern to achieve and maintain optimal health.

Abstract
Gastrointestinal reflux disease (GERD) is a chronic, highly prevalent condition in the United States. GERD can significantly impact quality of life and lead to complications including aspiration pneumonia, esophageal stricture, Barrett's esophagus (BE) and esophageal cancer. Obesity is a risk factor for GERD, which often improves with weight loss and bariatric surgery. Though the incidence of bariatric surgery, in particular, minimally invasive sleeve gastrectomy, has risen in recent years, emerging data has revealed that the severity or new onset of GERD may follow bariatric surgery. We performed a literature review to provide a detailed analysis of GERD with an emphasis on bariatric surgery as both the cure and the cause for GERD in the morbidly obese population. We also describe the pathophysiological mechanisms, management approach and treatment strategies of GERD following bariatric surgery.

Abstract
Metabolic/bariatric surgery is currently the most effective measure to treat morbid obesity and obesity-related comorbidities such as type 2 diabetes. It has proven effective not only in terms of short-term weight loss, but also in maintaining the lower body weight for several decades. Such weight loss improves patient quality of life and extends life expectancy. It is crucial for patients to understand the likely results of a given bariatric procedure so that they can make an informed decision about whether to undergo surgery. The amount of weight loss after metabolic/bariatric surgery is usually the most important outcome of interest to patients considering surgical treatment. It is also the most common primary endpoint for healthcare providers. Patients undergoing surgery want tangible and realistic expectations about how much weight they could lose after surgery, and healthcare professionals need to determine at each follow-up visit after surgery whether patients are on track to reach their weight loss target so they can provide timely intervention to patients with insufficient weight loss or weight regain. Weight loss after metabolic/bariatric surgery is influenced by many clinical variables, including initial body mass index, age, gender, ethnicity, and type of surgery. A well-validated chronological weight loss prediction model would enable patient-centered counseling and goal setting. This review summarizes and compares several publicly available prediction models.

Abstract
BACKGROUND Severe obesity is associated with complications following arthroplasty, leading surgeons to increasingly counsel patients regarding weight loss. For patients seeking arthroplasty, learning that severe obesity may be a relative contraindication to surgery can create a challenging clinical interaction. We sought to describe the self-reported health of United States (US) adults who had severe obesity and osteoarthritis (OA) to better understand patient perspectives. METHODS The National Health and Nutrition Examination Survey, a nationally representative sample of the US population, was used to identify adult participants who had a body mass index (BMI) over 35 and an OA diagnosis. In total, 889 participants representing a US population of 9,604,722 were included. Self-reported health was dichotomized as poor to fair versus good to excellent. Analyses were weighted to produce national estimates. Associations between obesity severity and patient characteristics with self-reported health were assessed. RESULTS Of US adults with a BMI over 35 and OA diagnosis, 64% rated their health as good or better. For adults who had a BMI over 45, 55% still reported their health as good or better. The strongest predictors of self-reported health were measures of physical functioning. Only 37% of participants who had much difficulty walking a quarter mile rated their health as good or better compared to 86% without difficulty (P < .001). CONCLUSION Approximately two-thirds of patients who have severe obesity and OA do not perceive their health as compromised and consider decreased physical function as the primary driver of decreased health. This suggests that counseling about the association between obesity and overall health may improve shared decision making and that patient satisfaction metrics may be difficult to interpret in these clinical situations.

Abstract
INTRODUCTION According to current guidelines, hormonal therapy may be applied in endometrioid type endometrial cancer as an alternative to surgery for fertility preservation and in medically unfit patients. Since it is unknown how often hormonal therapy is applied, the objective of this study was to investigate trends over time in hormonal therapy use in the background of the overall incidence of endometrial cancer. METHODS All patients with endometrial cancer (n=48 222) registered in the Netherlands Cancer Registry in the period 1989-2018 were included. European age-standardized incidence rates with corresponding estimated annual percentage change were calculated to describe trends in the incidence of endometrial cancer. The use of hormonal therapy was analyzed in the three periods 1989-1998, 1999-2008, and 2009-2018 for the following sub-groups: primary and adjuvant therapy, International Federation of Gynecology and Oncology (FIGO) stage I-II and III-IV, and by age group. RESULTS The European age-standardized incidence rate of endometrioid endometrial cancer peaked in 2004 with a significant increase from 1989 to 2004 (annual percentage change 0.55; 95% CI 0.10 to 0.99, p=0.020) and a subsequent decrease from 2005 to 2018 (annual percentage change -1.79; 95% CI -2.28 to -1.31, p<0.001). The incidence rate of non-endometrioid type endometrial cancer increased significantly in the study period. Hormonal therapy was used in 1482 (3.5%) patients with endometrioid endometrial cancer. Among patients with FIGO stage I aged ≤40 years, hormonal therapy increased from 0% in 1989-1998 to 27% in 2009-2018. Primary hormonal treatment increased from 175 patients (5.5%) to 329 patients (7.8%) in those aged ≥75 years. Adjuvant hormonal treatment was mostly used in advanced stage endometrial cancer. CONCLUSIONS The use of primary hormonal therapy in endometrioid type endometrial cancer increased over time in patients aged ≤40 years and among elderly patients. The observed trends in the current use of hormonal therapy support the need to study the effect of hormonal treatment in elderly patients and as adjuvant treatment in advanced stage endometrial cancer.

Abstract
AIMS AND OBJECTIVES To explore the relationship between patient obesity and nursing workload, and discuss the nursing activities most affected by patient obesity. BACKGROUND The increasing number of patients with obesity, and the severity of obesity, impacts the healthcare workforce, particularly to nurses who provide most direct care to patients. There is growing evidence to suggest that patient obesity may increase nursing workload and time taken for clinical care. DESIGN Integrative review. METHODS A comprehensive search of academic databases for primary research related to patient obesity and nursing workload, published since 2000, was conducted. References of relevant articles were hand-searched. RESULTS 27 articles were analysed. Analysis was undertaken at the levels of patient characteristics, nursing work and the healthcare system. The increasing number of patients with obesity, and the severity of patient obesity, increases nursing workload by affecting nursing time needed to deliver care. An increased number of nurses, particularly with increased clinical skill, are needed to deliver care meeting these increased needs. Organisational change is required to provide infrastructure and bariatric equipment that enables effective nursing care of patients with obesity. Organisations must consider additional time and staff needs when delivering care for patients with obesity. CONCLUSIONS The current health system is not established to address the challenge of providing nursing care to the increasing numbers of patients with obesity. Further research on accurately and objectively quantifying the impact and severity of patient obesity on nursing clinical activities is required. RELEVANCE TO CLINICAL PRACTICE When determining staffing, healthcare organisations must consider the increased nursing staff, time and clinical skill required to provide care for patients with obesity. Healthcare organisations should implement policies that ensure sufficient staffing in areas where care of patients with obesity is prevalent, and provide training for and workplace availability of bariatric equipment.

Abstract
OBJECTIVES Bilirubin is a biochemical substance with metabolic benefits. The objective of this research was to elucidate the association between serum bilirubin levels and metabolic alterations in different obesity phenotypes. METHODS In total, 1,042 drug-naive participants were included in the study. Of them, 541 were obese patients and 501 were age-matched and sex-matched healthy control subjects. The obese patients were divided into metabolically healthy obesity (MHO) group and metabolically unhealthy obesity (MUHO) group according to the levels of fasting plasma glucose (FBG), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and blood pressure (BP). Clinical and biochemical parameters including total bilirubin (TBil), indirect bilirubin (IBil) and direct bilirubin (DBil) were measured. ANOVA or Kruskal-Wallis H test was used to test differences among the three groups. Pearson and Spearman correlations were used to analyze the relationships between two parameters. The relationships between bilirubin and other variables were analyzed using Multivariate regression analysis. RESULTS MHO group had favorable blood pressure, glucose and lipids profiles, along with increased TBil and DBil, and decreased high-sensitivity C-reactive protein (hsCRP) and homeostasis model assessment of insulin resistance (HOMA-IR) levels when compared to MUHO group (P < 0.05 for all). TBil and DBil were negatively correlated with total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), fasting insulin (FINS), hsCRP and HOMA-IR, even after adjusted for age, gender and BMI (all P <0.01). Multivariate regression analysis demonstrated that HOMA-IR was independently correlated with TBil and DBIi levels (β = -0.400, P < 0.01). CONCLUSION MHO group harbors increased bilirubin level compared with MUHO group. HOMA-IR was independently correlated with TBil and DBIi levels.

Abstract
INTRODUCTION Bariatric surgery offers the most effective treatment for obesity, ameliorating or even reverting associated metabolic disorders, such as type 2 diabetes. We sought to determine the effects of bariatric surgery on circulating microRNAs (miRNAs) that have been implicated in the metabolic cross talk between the liver and adipose tissue. RESEARCH DESIGN AND METHODS We measured 30 miRNAs in 155 morbidly obese patients and 47 controls and defined associations between miRNAs and metabolic parameters. Patients were followed up for 12 months after bariatric surgery. Key findings were replicated in a separate cohort of bariatric surgery patients with up to 18 months of follow-up. RESULTS Higher circulating levels of liver-related miRNAs, such as miR-122, miR-885-5 p or miR-192 were observed in morbidly obese patients. The levels of these miRNAs were positively correlated with body mass index, percentage fat mass, blood glucose levels and liver transaminases. Elevated levels of circulating liver-derived miRNAs were reversed to levels of non-obese controls within 3 months after bariatric surgery. In contrast, putative adipose tissue-derived miRNAs remained unchanged (miR-99b) or increased (miR-221, miR-222) after bariatric surgery, suggesting a minor contribution of white adipose tissue to circulating miRNA levels. Circulating levels of liver-derived miRNAs normalized along with the endocrine and metabolic recovery of bariatric surgery, independent of the fat percentage reduction. CONCLUSIONS Since liver miRNAs play a crucial role in the regulation of hepatic biochemical processes, future studies are warranted to assess whether they may serve as determinants or mediators of metabolic risk in morbidly obese patients.

Abstract
INTRODUCTION The objective of this study was to study associations of a wide range of halogenated biphenyls, dibenzo-p-dioxins, dibenzofurans and diphenylethers with body mass index (BMI) and evaluate changes in their concentration following bariatric surgery. METHODS Subcutaneous fat, visceral fat and liver tissue samples were collected from 106 patients undergoing Roux-en-Y gastric bypass surgery for weight loss or patients who were undergoing abdominal surgery for nonbariatric reasons. We measured concentrations of an extensive panel of chlorinated and brominated biphenyls, dioxins, and furans, and brominated diphenylethers in the samples. We conducted linear regression to examine associations with BMI, adjusting for age and gender. Changes in concentration for indicator chemicals were evaluated in samples collected following bariatric surgery in a small subpopulation. RESULTS After adjustments for age and gender and correction for multiple testing, seven ortho-chlorinated biphenyls, one nonortho-chlorinated biphenyl, four PCDD/Fs and one ortho-brominated biphenyl were associated with BMI. The strongest associations between BMI and lipid-adjusted concentrations were seen with PCB-105 in subcutaneous fat (beta = 16.838 P-val = 1.45E-06) PCB-126 in visceral fat (beta = 15.067 P-val = 7.72E-06) and PCB-118 (beta = 14.101 P-val = 2.66E-05) in liver. The concentrations of sum PCBs, chlorinated toxic equivalent quantity (TEQ's) and brominated compounds increased significantly with weight loss in subcutaneous fat in a group of ten individuals resampled up to five years after bariatric surgery and substantial weight loss. CONCLUSION We show that selected polychlorinated biphenyls PCBs and structurally related polychlorinated dibenzo-p-dioxins dibenzofurans (PCDD/Fs) were associated with BMI. Concentrations of these lipophilic compounds in subcutaneous fat increased following bariatric surgery.

Abstract
OBJECTIVE To compare post-operative length of stay and complication rates of matched obese and non-obese patients in an enhanced recovery (ERAS) program after open gynecologic cancer surgery. METHODS We performed an observational cohort study of patients (n=1225) undergoing open surgery from November 2014 to November 2018 at a tertiary cancer center. Patients undergoing multidisciplinary procedures, non-oncologic surgery, or procedures in addition to abdominal surgery were excluded (n=190). Obese and non-obese patients were matched by date, age, disease status, and surgical complexity. The primary outcome was post-operative length of stay. Secondary outcomes included 30-day peri-operative complications, re-operation, re-admission, opioid use, and program compliance. RESULTS After matching, 696 patients (348 obese, 348 non-obese) with median age of 57 years (IQR 48-66) were analyzed. Obese patients had a longer median procedure time (218 min vs 192.5 min, p<0.001) and greater median estimated blood loss (300 mL vs 200 mL, p<0.001). Median (IQR) post-operative length of stay was the same for obese and non-obese patients: 3 days (IQR 2-4). Obese and non-obese patients had similar rates of grade III-IV complications (10.9% and 6.6%, respectively, p=0.06), re-operation (2.3% and 1.4%, respectively, p=0.58), and re-admission (11.8% and 8.0%, respectively, p=0.13). Grade I-II complications were more common among obese patients (62.4% vs 48.3%, p<0.001) because they had more wound complications (17.8% vs 4.9%, p<0.001). Obese patients received more opioids both during surgery (morphine equivalent dose 57.25 mg (IQR 35-72.5) vs 50 mg (IQR 25-622.5), p=0.003) and after surgery (morphine equivalent daily dose 45 mg/day (IQR 10-96.2) vs 29.37 mg/day (IQR 7.5-70), p=0.01). Obese and non-obese patients had similar ERAS program compliance (70.1% and 69.8%, respectively, p=0.32). CONCLUSIONS Neither post-operative length of stay nor the rate of serious complications differed significantly despite longer surgeries, greater blood loss, and more opioid use among obese patients. An ERAS program was safe, effective, and feasible for obese patients with suspected gynecologic cancer.

Abstract
The effect of intra-operative intravenous methadone on quality of postoperative recovery was compared with morphine after laparoscopic gastroplasty. We included 137 adult patients with a body mass index > 35 kg.m-2 who underwent bariatric surgery. Patients were allocated at random to receive either intra-operative methadone (n = 69) or morphine (n = 68). All patients received the same postoperative care and analgesia. The primary outcome of postoperative quality of recovery was assessed using the Quality of Recovery-40 questionnaire total score 24 h after surgery. Secondary outcomes were assessed in the post-anaesthesia care unit the night of the day of surgery (T1), in the morning after surgery (T2); and at night on the day following surgery (T3). The median (IQR [range]) total Quality of Recovery-40 questionnaire score of 194 (190-197 [165-200]) was higher (p < 0.0001) in the methadone group compared with the score of 181 (174-185.5 [121-200]) in the morphine group. In the post-anaesthesia care unit, the pain burden; incidence of nausea and vomiting; rescue morphine dose; and time to discharge, were significantly lower in the methadone group. On the ward, the methadone group had a lower: incidence of rescue morphine requests at T1 (5.8 vs. 54.4%, p < 0.0001) and T2 (0 vs. 20.1%, p < 0.0001); and incidence of nausea (21.7 vs. 41.2%, p = 0.014), compared with the morphine group. We conclude that intra-operative intravenous methadone improved quality of recovery in patients who underwent laparoscopic gastroplasty, compared with intra-operative morphine. Methadone also reduced postoperative pain, postoperative opioid consumption and the incidence of opioid-related adverse events.

Abstract
BACKGROUND Obesity control in Prader-Willi syndrome (PWS) is notoriously difficult. The role of bariatric surgery in PWS remains controversial as long-term data are lacking. OBJECTIVES To evaluate the 10-year outcomes of bariatric surgery in PWS. METHODS This was a prospective observational study on PWS patients who received bariatric surgery and multidisciplinary follow-up programmes for obesity control. Outcomes on weight reduction and comorbidity resolution were evaluated. RESULTS Between 2008 and 2013, five PWS patients (two males, mean age 19.2 ± 3.0 years) with body mass index of 47.3 ± 6.9 kg m-2 received sleeve gastrectomy (n = 2), one anastomosis gastric bypass (n = 2), and Roux-en-Y gastric bypass (n = 1) after failing all non-operative weight loss programmes. The median follow-up was 8.4 ± 2.2 years. The best mean percentage of total weight loss (%TWL) was achieved at 2 years (24.7%). %TWL dropped to 23.3% at 3 years, 11.9% at 5 years, 4.1% at 8 years, and 0% at 10 years. Each patient had at least three comorbidities preoperatively, but none of them had resolution of any one of the comorbidities at the last follow-up. CONCLUSIONS Bariatric surgery could not produce sustainable long-term weight loss or comorbidity resolution in PWS. This study suggests that bariatric surgery cannot be recommended to PWS patients as a standard treatment.

Abstract
Severely energy-restricted diets are used in obesity management, but their efficacy in people with class III obesity (body mass index ≥40 kg/m2) is uncertain. The aims of this systematic review and meta-analysis were to determine the effectiveness and characteristics of severely energy-restricted diets in people with class III obesity. As there was a lack of publications reporting long-term dietary interventions and randomised controlled trial designs, our original publication inclusion criteria were broadened to include uncontrolled study designs and a higher upper limit of energy intake. Eligible publications reported studies including adults with class III obesity and that assessed a diet with daily energy intake ≤5000 kJ for ≥4 weeks. Among 572 unique publications from 4 databases, 11 were eligible and 10 were suitable for meta-analysis. Our original intention was to classify comparison arms into short-term (<6 months) and long-term (>1 year) interventions. Due to the lack of long-term data found, comparison arms were classified according to the commonalities in dietary intervention length among the included publications, namely dietary interventions of 4 weeks' duration and those of ≥6 weeks' duration. After a 4-week severely energy-restricted diet intervention, the pooled average weight loss was 9.81 (95% confidence interval 10.80, 8.83) kg, with a 95% prediction interval of 6.38 to 13.25 kg, representing a loss of approximately 4.1 to 8.6% of initial body weight. Diets ≥6 weeks' duration produced 25.78 (29.42, 22.15) kg pooled average weight loss, with a 95% prediction interval of 13.77 to 37.80 kg, representing approximately 10.2 to 28.0% weight loss. Daily dietary prescriptions ranged from 330 to 5000 kJ (mean ± standard deviation 2260 ± 1400 kJ), and had wide variations in macronutrient composition. The diets were administered mostly via liquid meal replacement products. While the included publications had a moderate risk of bias score, which may inflate reported weight loss outcomes, the published data to date suggest that severely energy-restricted diets, delivered via diets of varying composition, effectively produce clinically relevant weight loss (≥10% of initial body weight) when used for 6 weeks or more in people with class III obesity.

Abstract
INTRODUCTION Bariatric surgery (BS) has gained popularity in order to treat morbid obesity. However, post-operative (PO) neurologic complications have become increasingly recognized. Our aim was to examine incidence, clinical presentation, and outcomes of neurologic disorders secondary to BS. METHODS Patients who underwent BS between the years 2012 and 2015 at Parma University were included in this survey, and assessed before (T0) and 1 year after surgery (T1). Baseline characteristics and medical comorbidities, type of surgery, and PO complications were retrieved. Patients with a previous history of peripheral neuropathic disease were excluded from the analysis. If a patient presented with a new onset neurologic symptom including extremity numbness, paresthesia, muscle weakness, the status was considered "positive" for PO-neuropathy. RESULTS Overall, we retrieved data from 61 patients (n=30 Roux-en-Y Gastric bypasses, n=31 Gastric banding; 81.0% females). Of them, 7 (11.4%) developed some signs of PO-neuropathy, that eventually disappeared at T+24 months. The most common manifestations were paresthesia (n=6) and muscle weakness (n=4), similarly distributed in Gastric Bypass (n=4) and Gastric Banding (n=3) groups. Although patients affected by PO-neuropathy exhibited higher SF-36 score at T0 (p=0.018), no significant differences were found regarding BMI (T0, T1), percentual weight loss, serological data (i.e. vitamin B1, B2, B6, B12: in all cases p>0.05). CONCLUSION PO-BS neuropathy is usually associated with lower levels of vitamin B1, B2, B12. However, no differences in PO-BMI, excess weight loss, and metabolic data levels were found. Larger data and more extended follow-up are required to validate our results.

Abstract
Obesity is a health issue that can lead to medical and psychological problems. Recently, bariatric surgery has become the best choice for treatment of selected candidates. As the number of bariatric surgeries increases, various related postoperative complications are being encountered. Most studies have been concerned with abdominal complications and thoracic complications were beyond their scope. The aim of this report was to review thoracic complications following bariatric surgery, in terms of incidence, management, and outcome. A literature search of English language published data concerning thoracic complications related to or following bariatric surgery was performed in November 2018. A total of 10,145 results were found. After screening titles and abstracts, 10,060 noneligible publications were excluded. Eighty-five publications were potentially eligible and their full texts were analyzed. After excluding overlapping series of patients, 44 studies were selected. These included 934 patients. Females accounted for 87.9% of the included patients. Ages ranged between 21 and 64 years (mean 43.86 ± 4.4 years). Most frequently encountered complications were esophageal (80.84%) followed by pulmonary (17.45%). The majority of esophageal complications were functional (82.38%) in contrast to the pulmonary type that were mostly organic (87.73%). There were 5 documented deaths. We concluded that thoracic complications are not infrequent after bariatric surgery. Esophageal and pulmonary are the most common thoracic complications reported. The outcome is usually favorable. Mortality may be avoided when complications are detected early and well-managed.

Abstract
Background General anaesthesia leads to atelectasis, reduced end-expiratory lung volume (EELV), and diminished arterial oxygenation in obese patients. We hypothesized that a combination of a recruitment manoeuvre (RM) and individualized positive end-expiratory pressure (PEEP) can avoid these effects. Methods Patients with a BMI ≥35 kg m -2 undergoing elective laparoscopic surgery were randomly allocated to mechanical ventilation with a tidal volume of 8 ml kg -1 predicted body weight and (i) an RM followed by individualized PEEP titrated using electrical impedance tomography (PEEP IND ) or (ii) no RM and PEEP of 5 cm H 2 O (PEEP 5 ). Gas exchange, regional ventilation distribution, and EELV (multiple breath nitrogen washout method) were determined before, during, and after anaesthesia. The primary end point was the ratio of arterial partial pressure of oxygen to inspiratory oxygen fraction ( P aO 2 / F iO 2 ). Results For PEEP IND ( n =25) and PEEP 5 ( n =25) arms together, P aO 2 / F iO 2 and EELV decreased by 15 kPa [95% confidence interval (CI) 11-20 kPa, P <0.001] and 1.2 litres (95% CI 0.9-1.6 litres, P <0.001), respectively, after intubation. Mean ( sd ) PEEP IND was 18.5 (5.6) cm H 2 O. In the PEEP IND arm, P aO 2 / F iO 2 before extubation was 23 kPa higher (95% CI 16-29 kPa; P <0.001), EELV was 1.8 litres larger (95% CI 1.5-2.2 litres; P <0.001), driving pressure was 6.7 cm H 2 O lower (95% CI 5.4-7.9 cm H 2 O; P <0.001), and regional ventilation was more equally distributed than for PEEP 5 . After extubation, however, these differences between the arms vanished. Conclusions In obese patients, an RM and higher PEEP IND restored EELV, regional ventilation distribution, and oxygenation during anaesthesia, but these differences did not persist after extubation. Therefore, lung protection strategies should include the postoperative period. Clinical trial registration German clinical trials register DRKS00004199, www.who.int/ictrp/network/drks2/en/ .

Abstract
Background: In high-fat diet-fed mice, interleukin-1 beta (IL-1 beta) has been shown to play a key role in hepatic steatosis. However, it remains unknown whether IL-1 beta could be associated with different grades of steatosis in obese humans. Materials and Methods: Morbidly obese patients (n = 124) aged 18–65 years were divided into four groups: no steatosis (controls), mild steatosis, moderate steatosis, and severe steatosis using abdominal ultrasound. IL-1 beta serum levels and liver function tests were measured and significant differences were estimated by one-way ANOVA followed by Tukey test. Results: IL-1 beta serum levels significantly increased in morbidly obese patients with mild (11.38 ± 2.40 pg/ml), moderate (16.72 ± 2.47 pg/ml), and severe steatosis (23.29 ± 5.2 pg/ml) as compared to controls (7.78 ± 2.26 pg/ml). Liver function tests did not significantly change among different grades of steatosis. Conclusion: IL-1 beta serum levels associate better with steatosis degree than liver function tests in morbidly obese population.

Abstract
Purpose: This article describes the knowledge, attitudes, and practice of in-patient physiotherapists in Ontario regarding the treatment of patients who are super-morbidly obese (SMO; i.e., those whose BMI is >50). Method: A 62-item questionnaire was developed to assess demographics, sources of knowledge, current practice, and attitudes such as confidence, willingness, and the perceived effectiveness of treatment. It was distributed electronically using FluidSurveys. All physiotherapists working in a clinical role with adults in an in-patient setting in Ontario were eligible to participate. Results: A total of 276 physiotherapists completed the survey. Most of them had learned about the treatment from non-structured sources such as clinical experience. More than half (52%) of the participants disagreed that their place of employment was well prepared to facilitate the treatment of patients who are SMO. The majority of respondents were confident in treating these patients, were willing to treat them (82%), and believed that physiotherapy would improve at least one health outcome (96%) for them; however, 46% were reluctant to treat for fear of personal injury. Participants most commonly felt limited by lack of equipment and lack of staff to assist. Conclusions: Physiotherapists have positive attitudes toward treating patients who are SMO, and increased equipment and staff to assist, as well as appropriate education, may decrease the fear of injury for physiotherapists while treating these patients and improve health outcomes for them.

Abstract
BACKGROUND The role of obesity as a risk factor for difficult intubation remains controversial. We primarily assessed the association between body mass index (BMI) and difficult tracheal intubation. METHODS We analysed electronic records of more than 67 000 adults having elective non-cardiac surgery requiring tracheal intubation at the Cleveland Clinic between 2011 and 2015. The association between BMI and difficult intubation, defined as more than one intubation attempt, was assessed using multivariable logistic regression adjusting for pre-specified confounders. RESULTS Amongst 40 183 patients with BMI <30 kg m-2 and 27 519 with BMI ≥30 kg m-2, 9% required more than one intubation attempt. Increasing BMI up to 30 kg m-2 was significantly associated with increased odds of more than one intubation attempt [odds ratio (OR): 1.03; 97.5% confidence interval (CI): 1.02, 1.04] per unit increase in BMI, P < 0.001. However, the odds of difficult intubation remained unchanged once BMI exceeded 30 kg m-2 (P = 0.08). The results were similar when analysis was restricted to patients without history of airway abnormalities in whom intubation was attempted using a standard direct laryngoscope (OR: 1.03; 99.4% CI: 1.01, 1.04) per kg m-2 increase in BMI <30 kg m-2). CONCLUSIONS Increasing BMI was associated with increasing odds of difficult intubation in the lean range. At higher BMI, the odds of difficult intubation remain elevated, but there is no additional increase in odds with further increase in BMI. Obese patients were thus harder to intubate than lean ones, but difficult intubation was no more likely in morbidly obese patients than in those who were only slightly obese.

Abstract
Purpose Obesity is a well-known of risk factor for atherosclerosis and the amount of visceral adipose tissue is considered as an independent predictor of coronary artery disease (CAD). An aim of the study was to investigate the distribution of intrathoracic adipose tissue in morbidly obese patients. Material and methods Fifty-one patients with morbid obesity (BMI ≥ 40 kg/m2) and thirty controls were scanned in a coronary calcium scoring protocol. Control group consisted of patients scanned due to a clinical suspicion of CAD, who did not fulfill obesity criteria. The amount of adipose tissue was measured as epicardial adipose tissue (EAT) thickness, pericoronary fat (PCF) thickness, total intra-pericardial fat (IPF) volume, and total intrathoracic fat (ITF) volume. Results Mean BMI of obese patients and controls was 47.3 and 26.5, respectively (p < 0.0001). Patients with obesity and controls did not differ with respect to mean EAT, mean PCF, and IPF. However, ITF was lower in obesity group than in control group (268 vs. 332 cm3, respectively; p < 0.03). Moreover, ROC analysis presented relation between obesity and the superior EAT thickness, PCF at LCX, mean PCF, ITF, and chest soft tissue (CST) thickness (p < 0.03). CST thickness of > 60 mm was the parameter that presented the strongest association with morbid obesity (AUC 0.95; p < 0.0001). Conlcusions Increased chest soft tissue thickness but not the increased intrathoracic adipose tissue volume was associated with morbid obesity. Since the quantity of the pericardiac fat is not directly related to the obesity, its accumulation may be related to a mechanism different than that of subcutaneous adipose tissue growth.

Abstract
Background Addressing the prevalence of severe obesity and its concomitant morbidities is widely acknowledged as one of the most pressing global health priorities. Nevertheless, a paucity of effective interventions and universal pressure on health‐care budgets means that access to obesity treatments is often limited. Although health‐care rationing can be conceived as a socially constructed process, little is known about how decisions emerge within the context of face‐to‐face doctor–patient interactions. Methods In this study, we used in‐depth interviews and clinic observations to investigate clinicians’ (n = 11) and patients’ (n = 22) experiences of the rationing of obesity surgery and to examine how broader cultural assumptions around personal responsibility for health emerged in the context of clinical interactions. Results Patients and clinicians worked within similar frameworks when it came to self‐responsibility for health and the appropriateness of providing publicly‐funded weight loss surgery. Issues around personal accountability dominated consultations, and patients were expected to provide narratives of the development of their obesity and to account for the failure of previous interventions. Clinicians faced the added pressure of having to prioritise a limited number of patients for surgery, which was predominantly managed through mandating pre‐referral weight loss targets. Discussion Although clinicians sought to maintain an empathic attitude towards individual patients, in practice they were conflicted by their responsibility to ration health‐care resources and tended to rely on entrenched models of behaviour change to allocate treatment. As a result, the content of consultations was mostly focused on issues of personal responsibility, reflecting wider stigmatized attitudes towards extreme obesity.

Abstract
OBJECTIVE The aim of this study was to evaluate the vertical component of the ground reaction force, plantar pressure, contact area of the feet and double-support time using static and dynamic (gait) baropodometry before and after bariatric surgery. METHODS Sixteen individuals with a body mass index of between 35 and 55 were evaluated before and after bariatric surgery. Thirteen patients (81.3%) were female and three (18.8%) male and their average age was 46±10 (21-60) years. An FSCAN system (version 3848) was used for baropodometric analyses (1 km/h and 3 km/h). The peak plantar pressure and ground reaction force were measured for the rear foot and forefoot. The double-support time and foot contact area were measured during gait. RESULTS There were reductions in the ground reaction force in the forefoot and rear foot and in the foot contact area in all evaluations and of the double-support time at 3 km/h, as well as a significant reduction in the body mass index at six months post-surgery. The peak pressure did not vary at 1 km/h and at 3 km/h, reductions in peak pressure were observed in the left and right rear feet and left forefoot. CONCLUSIONS Weight loss after bariatric surgery resulted in decreases in the ground reaction force and contact area of the foot. Plantar pressure was decreased at 3 km/h, especially in the forefoot. There was an increase in rhythm because of a reduction in the double-support time at 3 km/h.

Abstract
BACKGROUND Tubo-ovarian abscess (TOA) arises in most cases from pelvic infection. Appropriate treatment includes use of antimicrobials and, especially in patients with increased BMI, drainage of the contents. CASE A 44-year-old morbidly obese woman (BMI 72) had a persistent TOA despite receiving antibiotic treatment for four months. She had no history of diabetes, and denied being sexually active. Imaging demonstrated a pelvic abscess of 14.9 × 8.9 × 11.1 cm. Successful percutaneous drainage was performed yielding purulent material which grew Candida albicans. The patient recovered after drainage of the abscess and the addition of fluconazole to her antimicrobials. She had no apparent risk factor for acquiring such an opportunistic infection, other than her morbid obesity. CONCLUSION Because morbid obesity may confer a relative immunodeficiency, morbidly obese patients may develop unusual infections such as opportunistic fungal abscesses.

Abstract
Frotteurism is a perverted sexual behaviour wherein the person tends to rub or bring about physical contact between his genitals and an unrelated female or male to derive sexual pleasure. Moreover, frotteurism is a common phenomenon among the general population which usually goes unnoticed or overlooked. Nevertheless, public frottage has legal implications in almost all countries over the world. But, when frotteurism manifests on the backdrop of psychiatric illness or as a developmental abnormality then it is worth discussing what the legal liability would be. The present case report is based on hypersexual frotteuristic behaviour manifested on the background of a concealed psychiatric illness, featuring depression and obsessive compulsive disease. The hypersexual behaviour manifested in the form of masturbation with features of frotteurism and subsequent development of depression. Nevertheless, compulsive manifestation of frotteuristic behaviour and subsequent development of morbid depression is rare. This paper describes a 12-year-old boy having unrestrained impulsive frotteurism with his peers, school mates and with his younger brother. He was conscious of the fact and feeling guilty of what he was doing but unable to restrain himself. It was followed by the development of symptoms of depression which was treated with Sertraline. Concurrent psychiatric counseling and rehabilitation measures were taken too. There was complete remission of the symptoms 6 months after the onset of treatment and without relapse thereafter. The paper discusses the differential diagnosis and management of hypersexual behaviour.

Abstract
PURPOSE We determined the effect of dietary fat and oxalate on fecal fat excretion and urine parameters in a rat model of Roux-en-Y gastric bypass surgery. MATERIALS AND METHODS Diet induced obese Sprague-Dawley® rats underwent sham surgery as controls (16), or Roux-en-Y gastric bypass surgery (19). After recovery, rats had free access to a normal calcium, high fat (40%) diet with or without 1.5% potassium oxalate for 5 weeks and then a normal (10%) fat diet for 2 weeks. Stool and urine were collected after each period. Fecal fat was determined by gas chromatography and urine metabolites were evaluated by assay spectrophotometry. RESULTS Daily fecal fat excretion remained low in controls on either diet. However, Roux-en-Y gastric bypass rats ingested a food quantity similar to that of controls but had eightfold higher fecal fat excretion (p <0.001) and heavier stools (p = 0.02). Compared to controls, gastric bypass rats on the high fat diet with potassium oxalate had a fivefold increase in urine oxalate excretion (p <0.001), while gastric bypass rats without potassium oxalate had a twofold increase in urine calcium (p <0.01). Lowering dietary fat in gastric bypass rats with potassium oxalate led to a 50% decrease in oxalate excretion (p <0.01), a 30% decrease in urine calcium and a 0.3 U increase in urine pH (p <0.001). CONCLUSIONS In this Roux-en-Y gastric bypass model high fat feeding resulted in steatorrhea, hyperoxaluria and low urine pH, which were partially reversible by lowering the dietary fat and oxalate content. Roux-en-Y gastric bypass rats on normal fat and no oxalate diets excreted twice as much oxalate as age matched, sham operated controls. Although Roux-en-Y gastric bypass hyperoxaluria appears primarily mediated by gut and diet, secondary causes of oxalogenesis from liver or other mechanisms deserve further exploration.

Abstract
Guidelines for the clinical management of obese, reproductive age women with reduced fertility in the USA are limited. Clinical professional organizations have yet to publish practice guidelines on this topic. Thus, treatment decisions are made at the provider and/or clinic level and the variation in clinic policy regarding fertility treatment for obese women is not readily available. Globally, there is an ongoing discussion among reproductive endocrinologists that practice in countries with government-funded health care about whether treatment should be restricted to women under a certain body mass index. Our analysis of a representative US population identified that differences exist in the utilization of fertility-related services according to female body mass. Women with class II/III obesity were the group reporting the highest percentage seeking medical attention to become pregnant, but the lowest percentage receiving medical or surgical fertility-related services, although these differences were not statistically significant. As the prevalence of obesity among women of reproductive age increases both in the USA and abroad, it is critical to consider the medical, social and ethical issues involved in allocating resources for fertility treatment. Ongoing monitoring of trends in service utilization in light of the obesity epidemic and delayed childbearing will provide further insight into this clinical health policy issue.
