Primary bariatric surgery has been proven to be effective in weight loss and improvement of weight-related metabolic co-morbidities. However, a small proportion of patients after bariatric surgery either have persistent hyperglycemia or relapse after initial remission of their metabolic disease. Revisional bariatric surgery has been evaluated extensively for weight recidivism and postoperative complications. However, there has not been any high-level evidence validating the utility of revisional bariatric surgery on recurrent metabolic diseases, especially diabetes...

INTRODUCTION: Improving tissue oxygenation is one of most important tasks in management of low cardiac output. Central venous oxygen saturation (ScvO2) and lactate are established criteria for monitoring the adequacy of tissue oxygenation. The venous-to-arterial carbon dioxide difference [P(v-a)CO2] is inversely associated with cardiac output. AIM: To study the use of P(v-a)CO2/C(a-v)O2 ratio as a marker of low cardiac output during Cardiopulmonary Bypass (CPB) in paediatric cardiac surgical patients...

Self-mixing interferometry (SMI) represents a robust, self-aligned technique for metrology applications. Recently, it has been shown that the detection of the frequency-modulated (FM) signal enhances the conventional SMI signal based on the amplitude modulation. Here, an all-optical, simple and effective alternative approach to detect the FM self-mixing signal is presented. We demonstrate the enhanced self-mixing approach using a laser diode emitting at 405 nm and a volume Bragg grating (VBG) to map frequency to intensity modulations for further optical detection...

The electrostatic gating of graphene field-effect transistors is demonstrated using a monolayer electrolyte. The electrolyte, cobalt crown ether phthalocyanine (CoCrPc) and LiClO4, is deposited as a monolayer on the graphene channel, essentially creating an additional two-dimensional layer on top of graphene. The crown ethers on the CoCrPc solvate lithium ions and the ion location is modulated by a backgate without requiring liquid solvent. Ions dope the channel by inducing image charges; the doping level (i...

205 Background: Indwelling pleural catheter (IPC) placement is an alternative to chemical pleurodesis for malignant pleural effusion (MPE), a complication of advanced cancer. In 1997 an IPC was approved which uses vacuum bottles (VB) for drainage (PleurX, Becton, Dickinson and Company, Franklin Lakes, NJ), and later another IPC system, which employs a manually operated vacuum pump (VP) for drainage (Aspira, Bard Access Systems, Salt Lake City, UT). Most studies comparing IPC versus chemical pleurodesis used the VB IPC...

BACKGROUND: Although vertical banded gastroplasty (VBG) is no longer performed in the USA, due to its popularity in 1980s, many patients still possess this anatomy with its inherent complications. The stomal stenosis secondary to tight ring or mesh is traditionally treated with surgical removal of the silastic ring or a complex revision, which was hampered by complications, technical complexity, and invasiveness. We described our experience of endoscopic management of this complex problem and the early outcomes...

Recent research has shown that using multiple diverse-bandgap photovoltaic (PV) cells in conjunction with a spectrum splitting optical system can significantly improve PV power generation efficiency. Although volume Bragg gratings (VBGs) can serve as effective spectrum splitters, the inherent dispersion of a VBG can be detrimental given a broad-spectrum input. The performance of a single holographic spectrum splitter element can be improved by utilizing multiple single volume gratings, each operating in a slightly different spectral band...
