Abstract
PURPOSE A significant proportion of patients experience insufficient weight loss or weight regain after bariatric surgery. There is a paucity of literature describing anti-obesity medication (AOM) use following bariatric surgery. We sought to identify prevalence and trends of AOM use following bariatric surgery. MATERIALS AND METHODS We utilized the IBM Explorys® database to identify all adults with prior bariatric surgery (Roux-en-Y gastric bypass or sleeve gastrectomy). Those prescribed AOMs (semaglutide, liraglutide, topiramate, phentermine/topiramate, naltrexone/bupropion, orlistat) within 5 years of surgery were further identified. Data was analyzed to characterize AOM utilization among different age, demographic, and comorbid populations. RESULTS A total of 59,160 adults with prior bariatric surgery were included. Among AOMs studies, prevalence of use was highest for topiramate (8%), followed by liraglutide (2.9%), phentermine/topiramate (1.03%), naltrexone/bupropion (0.95%) semaglutide (0.52%), and orlistat (0.17%). Age distribution varied, with the highest utilization among those age 35-39 years for topiramate, 40-44 years for phentermine/topiramate and naltrexone/bupropion, 45-49 years for semaglutide, and 65-69 years for liraglutide and orlistat. African American race was associated with higher utilization across all AOMs. Among comorbidities, hypertension, hyperlipidemia, and diabetes mellitus were most associated with AOM use. CONCLUSION Despite a relatively high incidence of weight regain, AOMs are underutilized following bariatric surgery. It is imperative that barriers to their use be addressed and that AOMs be considered earlier and more frequently in patients with insufficient weight loss or weight regain after bariatric surgery.

Abstract
PURPOSE OF REVIEW To comprehensively summarize the current body of literature on the topic of adjuvant and neoadjuvant pharmacotherapy used in combination with bariatric surgery. RECENT FINDINGS Anti-obesity medications (AOMs) have been used since the mid-1900s; however, their use in combination with bariatric surgery is a newer area of research that is rapidly growing. Pharmacotherapy may be used before (neoadjuvant) or after (adjuvant) bariatric surgery. Recent literature suggests that adjuvant AOMs may address weight regain and inadequate weight loss following bariatric surgery. Research on neoadjuvant AOM used to optimize weight loss before bariatric surgery is more limited. A literature review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Thirty-four studies were included after screening and exclusion of irrelevant records. Included studies were as follows: seven prospective studies on adjuvant AOM use, 23 retrospective studies on adjuvant AOM use, one prospective study on adjuvant and neoadjuvant AOM use, one retrospective study on adjuvant or neoadjuvant AOM use, one prospective study on neoadjuvant AOM use, and one case series on neoadjuvant AOM use. In the following scoping review, each of these studies is discussed with the goal of presenting a complete synthesis of the current body of literature on AOM use in combination with bariatric surgery.

Abstract
Post liver transplant obesity is associated with the development of metabolic disorders such as diabetes mellitus and nonalcoholic fatty liver disease and is a strong predictor of post-transplant mortality. Anti-obesity pharmacotherapy could serve as an effective adjunct to lifestyle modification in the post-transplant setting. Currently, utilization of anti-obesity medication in post liver transplant patients is limited by scarce data on their efficacy and safety in the post-transplant setting. Newer classes of anti-obesity medications, including the glucagon-like peptide 1 agonists (GLP-1) do not only help with weight loss but are effective anti-diabetic agents and are in further development for their potential hepatoprotective and renoprotective effects and reduction in cardiovascular risk. The objective of this manuscript was to critically review the efficacy and safety of anti-obesity pharmacotherapy in post-liver transplant patients.

Abstract
Excess body weight is a significant risk factor for the development and recurrence of many types of cancer. Patients with a history or current diagnosis of cancer who are overweight or have obesity have an increased risk of cancer treatment-related morbidity, recurrence, and decreased quality of life. Weight loss and maintenance of a healthy body weight may reduce cancer morbidity and recurrence in cancer survivors. While guidelines for cancer survivorship elaborate sufficiently on lifestyle interventions, little guidance is provided when considering additional therapies like anti-obesity pharmacotherapy or bariatric surgery for weight loss. This review will highlight and address current recommendations and feasible interventions that clinicians may consider to further reduce the incidence and recurrence of cancer in patients with obesity.

Abstract
INTRODUCTION The recent approval in the USA (Food and Drug Administration), Canada (Health Canada), UK (Medicines and Healthcare products Regulatory Agency), and EU (European Medicines Agency) of once-weekly injectable semaglutide 2.4 mg, as an adjunct to a calorie-controlled diet and increased physical activity, for chronic weight management provides health-care practitioners with an additional option when prescribing weight-loss medication. AREAS COVERED We describe the chemistry, mechanism of action, and pharmacological properties of semaglutide (a glucagon-like peptide 1 receptor agonist [GLP-1 RA]) and discuss clinical data and considerations for using once-weekly subcutaneous semaglutide 2.4 mg as treatment for overweight and obesity among patients with and without type 2 diabetes (T2D). EXPERT OPINION Once-weekly subcutaneous semaglutide 2.4 mg is the most efficacious medication approved for chronic weight management among patients with overweight and obesity, with and without T2D, and is the first drug to induce sustained double-digit reductions in percentage body weight over 1- to 2-year treatment periods. It demonstrates a similar safety and tolerability profile to other GLP-1 RAs. Semaglutide 2.4 mg treatment could dramatically improve clinical approaches to weight management, but the relatively high cost might prevent patients accessing treatment. Further research exploring the cost-effectiveness of subcutaneous semaglutide 2.4 mg is required.

Abstract
Older medications approved for chronic weight management (orlistat, naltrexone/bupropion, liraglutide 3 mg and, in the USA, phentermine/topiramate) have not been widely adopted by health care providers. Those medications produce only modest additional weight loss when used to augment lifestyle intervention. However, semaglutide 2.4 mg weekly has recently emerged and produces much more weight loss - on average 15% weight loss at 1 year. Semaglutide's enhanced efficacy and that its class (GLP-1 receptor analogs) is well-known may result in more clinicians adopting pharmacotherapy. Furthermore, the first dedicated cardiovascular outcome trial powered for superiority testing an anti-obesity medication (SELECT) is underway with semaglutide 2.4 mg. A positive outcome will further promote the concept that weight management should be a primary target for cardiometabolic disease control. In phase 3, tirzepatide and cagrilintide/semaglutide combination are showing promise for even greater weight loss efficacy. Another recently approved medication takes a personalized medicine approach; setmelanotide is approved as a therapy for those with some of the ultra-rare genetic diseases characterized by severe, early onset obesity. This chapter reviews the currently available and anticipated medications for chronic weight management as well as those approved for the genetic and syndromic obesities.

Abstract
Introduction: Healthcare providers (HCPs) see many patients with obesity-related complications and are therefore well placed to help treat obesity itself. However, limited collated information exists to help HCPs with the practical use of anti-obesity medications (AOMs). We focus on the initiation and maintenance of a glucagon-like peptide-1 receptor agonist (GLP-1 RA) for weight management, liraglutide 3.0 mg. Literature search was conducted between 25-28 November 2019 on PubMed and ClinicalTrials.gov.Areas covered: Clinical trial and real-world data describing weight-loss efficacy, cardiometabolic risk factors, incidence of adverse events (AEs), and persistence are presented to assist HCPs with patient discussions. Practical considerations to overcome barriers to optimal use are provided, equipping HCPs with the information required to aid with adherence to and persistence with AOMs. The use of other GLP-1- RA therapies in obesity is discussed in light of the recent US Food and Drug Administration approval of semaglutide 2.4 mg for weight management.Expert opinion: Liraglutide 3.0 mg provides benefits regarding weight loss and improvements in cardiometabolic risk factors. Promising areas of future research in the field of obesity include dual receptor agonists and the combination of glucagon-like peptide-1 receptor agonists with other molecules.

Abstract
PURPOSE OF REVIEW To discuss clinical outcomes, changes in weight, and weight loss strategies of patients with obesity post left ventricular assist device (LVAD) implantation. RECENT FINDINGS Despite increased complications in patients with obesity after LVAD implantation, survival is comparable to patients without obesity. A minority of patients with obesity lose significant weight and become eligible for heart transplantation after LVAD implantation. In fact, a great majority of such patients gain weight post-implantation. Obesity by itself should not be considered prohibitive for LVAD therapy but, rather, should be incorporated into the overall risk assessment for LVAD implantation. Concerted strategies should be developed to promote sustainable weight loss in patients with obesity and LVAD to improve quality of life, eligibility, and outcomes after heart transplantation. Investigation of the long-term impact of weight loss on patients with obesity with LVAD is warranted.

Abstract
BACKGROUND This pilot study evaluated whether adding phentermine to liraglutide would induce further weight loss in participants who had previously lost weight with liraglutide alone. SUBJECTS/METHODS Participants were 45 adults with obesity (75.6% female, 55.6% white, body mass index = 34.3 ± 4.7 kg/m2) who had lost an average of 12.6 ± 6.8% of initial weight during a prior 1-year randomized trial with liraglutide and intensive behavioral treatment. Participants were re-randomized, in a double-blinded fashion, to liraglutide 3.0 mg plus phentermine 15.0 mg (liraglutide-phentermine) or liraglutide plus placebo (liraglutide-placebo). Participants also were provided with four, 15-minute counseling sessions during the 12-week extension study. RESULTS At week 12, the liraglutide-phentermine and liraglutide-placebo groups lost a mean (±SEM) of 1.6 ± 0.6% and 0.1 ± 0.5% of re-randomization weight, respectively (p = 0.073). Two (9.1%) liraglutide-phentermine participants and one (4.3%) liraglutide-placebo participant lost ≥5% of re-randomization weight; 19 (86.4%) and 16 (69.9%) participants, respectively, maintained their full weight loss achieved in the prior 1-year trial (p = 0.125). Liraglutide-phentermine participants generally reported larger reductions in hunger and food preoccupation than liraglutide-placebo participants during the first 8 weeks of the extension study. CONCLUSIONS The combination of liraglutide and phentermine appeared to be well-tolerated but did not produce additional clinically meaningful weight loss in individuals who had already lost 12.6% of initial weight with liraglutide alone. TRIAL REGISTRATION ClinicalTrials.gov number, NCT02911818.

Abstract
AIMS/HYPOTHESIS This multicentre randomised double-blind placebo-controlled clinical trial assessed the efficacy and safety of a methionine aminopeptidase 2 (MetAP2) inhibitor, beloranib, in individuals with obesity (BMI ≥30 kg/m2) and type 2 diabetes (HbA1c 53-97 mmol/mol [7-11%] and fasting glucose <15.6 mmol/l). METHODS Participants were randomised (via a centralised interactive web response system) to placebo, 1.2 or 1.8 mg beloranib s.c. twice weekly for 26 weeks. Participants, investigators and the sponsor were blinded to group assignment. The primary endpoint was the change in weight from baseline to week 26. The trial was terminated early when beloranib development was stopped because of an imbalance of venous thromboembolism events in beloranib-treated individuals vs placebo that became evident during late-stage development of the drug. RESULTS In total, 153 participants were randomised, 51 to placebo, 52 to 1.2 mg beloranib and 50 to 1.8 mg beloranib. In participants who completed week 26, the least squares mean ± SE weight change (baseline 111 kg) was -3.1 ± 1.2% with placebo (n = 22) vs -13.5 ± 1.1% and -12.7 ± 1.3% with 1.2 and 1.8 mg beloranib, respectively (n = 25; n = 19; p < 0.0001). The change in HbA1c (baseline 67 mmol/mol [8.3%]) was -6.6 ± 2.2 mmol/mol (-0.6 ± 0.2%) with placebo vs -21.9 ± 2.2 mmol/mol (-2.0 ± 0.2%) or -21.9 ± 3.3 mmol/mol (-2.0 ± 0.3%) with 1.2 or 1.8 mg beloranib (p < 0.0001), respectively. The most common beloranib adverse events were sleep related. One beloranib-treated participant experienced a non-fatal pulmonary embolism. CONCLUSIONS/INTERPRETATION MetAP2 inhibitors represent a novel mechanism for producing meaningful weight loss and improvement in HbA1c.
