BACKGROUND: Bariatric surgery is the most effective treatment for severe obesity. However, following Roux-en-Y gastric bypass (RYGB) surgery, a small minority of patients develop new-onset alcohol use disorder (AUD), the aetiology of which is poorly understood. AIM: The aim is to construct a theory to explain the development of AUD among a sample of individuals who reported problematic drinking following RYGB. METHOD: Semi-structured interviews were conducted with eight RYGB patients diagnosed with AUD attending a multi-disciplinary outpatient weight management service at a public hospital in the Republic of Ireland...

Gitanjali Srivastava, Caroline M Apovian
More than one-third of adults in the USA have obesity, which causes, exacerbates or adversely impacts numerous medical comorbidities, including diabetes mellitus and cardiovascular disease. Despite intensive lifestyle modifications, the disease severity warrants further aggressive intervention, including pharmacotherapy, medical devices and bariatric surgery. Noninvasive anti-obesity drugs have thus now resurfaced as targeted adjunctive therapeutic approaches to intensive lifestyle intervention, bridging the gap between lifestyle and bariatric surgery...

INTRODUCTION: Modern metal-on-metal hip resurfacing arthroplasty has led to decreased revision rates and high implant survival rates as compared to prior generations of resurfacing. Many of the series that report on resurfacing outcomes focus upon patients treated with a diagnosis of osteoarthritis. Patients with inflammatory arthritis such as rheumatoid arthritis (RA) and ankylosing spondylitis (AS) are also treated in these series, however, their outcomes following resurfacing are underreported...

BACKGROUND: Syphilis infection has recently resurfaced as a significant public health problem. Although there has been a tremendous amount of research on the epidemiology of syphilis, there has been limited work done to synthesize the extensive body of research and systematically estimate patterns of disease within high-risk groups in the Americas. The purpose of this systematic review and meta-analysis is to (1) summarize recent patterns of syphilis infection in North and South America among four high-risk groups (MSM, transgender women, sex workers, and incarcerated individuals) from 1980 to 2016, (2) identify and differentiate regional geographic epidemiologic characteristics, and (3) compare the epidemics of the economically developed countries of North America from the developing countries and public health systems of Latin America and the Caribbean...

BACKGROUND: Loss of soft tissue in heel-calcaneal region is frequently caused by trauma, infection, or tumors. Limited availability of similar tissue becomes challenging, therefore, the use of free tissue transfer offers a solution. Our aim is to describe long term functional outcome of different free tissue transfers for these defects. PATIENTS AND METHODS: We retrospectively reviewed 24 consecutive cases of the heel-calcaneal defect between January 2009 and December 2014...

Importance: Thirty-day readmission to hospital after total hip arthroplasty (THA) has significant direct costs and is used as a marker of hospital performance. All-cause readmission is the only metric in current use, and risk factors for surgical readmission and those resulting in return to theater (RTT) are poorly understood. Objective: To determine whether patient-related predictors of all-cause, surgical, and RTT readmission after THA differ and which predictors are most significant...

Polymyxin B has resurfaced as a last-line treatment for multi-drug resistant Gram-negative bacteria. Accurate characterization and quantification of polymyxin B components is necessary to optimize this therapy. We developed and validated a robust, straightforward LC-MS/MS method to quantify polymyxin B1 and B2, the primary polymyxin B components, in various matrices (cation-adjusted Mueller-Hinton broth (CAMHB), human and rat plasma). Of sample preparation approaches investigated, two protein precipitation/extraction methods were developed as part of an analytical strategy based upon reverse-phase LC-MS/MS using electrospray ionization in positive multiple-reaction monitoring mode...
