VIKOR method for multiple criteria group decision making under 2-tuple linguistic neutrosophic environment

In this article, the VIKOR method is proposed to solve the multiple criteria group decision making (MCGDM) with 2-tuple linguistic neutrosophic numbers (2TLNNs). Firstly, the fundamental concepts, operation formulas and distance calculating method of 2TLNNs are introduced. Then some aggregation operators of 2TLNNs are reviewed. Thereafter, the original VIKOR method is extended to 2TLNNs and the calculating steps of VIKOR method with 2TLNNs are proposed. In the proposed method, it’s more reasonable and scientific for considering the conflicting criteria. Furthermore, the VIKOR are extended to interval-valued 2-tuple linguistic neutrosophic numbers (IV2TLNNs). Moreover, a numerical example for green supplier selection has been given to illustrate the new method and some comparisons are also conducted to further illustrate advantages of the new method

Elevation of hilar mossy cell activity suppresses hippocampal excitability and avoidance behavior

Modulation of hippocampal dentate gyrus (DG) excitability regulates anxiety. In the DG, glutamatergic mossy cells (MCs) receive the excitatory drive from principal granule cells (GCs) and mediate the feedback excitation and inhibition of GCs. However, the circuit mechanism by which MCs regulate anxiety-related information routing through hippocampal circuits remains unclear. Moreover, the correlation between MC activity and anxiety states is unclear. In this study, we first demonstrate, by means of calcium fiber photometry, that MC activity in the ventral hippocampus (vHPC) of mice increases while they explore anxiogenic environments. Next, juxtacellular recordings reveal that optogenetic activation of MCs preferentially recruits GABAergic neurons, thereby suppressing GCs and ventral CA1 neurons. Finally, chemogenetic excitation of MCs in the vHPC reduces avoidance behaviors in both healthy and anxious mice. These results not only indicate an anxiolytic role of MCs but also suggest that MCs may be a potential therapeutic target for anxiety disorders

An Overview of Regional Experiments on Biomass Burning Aerosols and Related Pollutants in Southeast Asia: From BASE-ASIA and the Dongsha Experiment to 7-SEAS

By modulating the Earth-atmosphere energy, hydrological and biogeochemical cycles, and affecting regional-to-global weather and climate, biomass burning is recognized as one of the major factors affecting the global carbon cycle. However, few comprehensive and wide-ranging experiments have been conducted to characterize biomass-burning pollutants in Southeast Asia (SEA) or assess their regional impact on meteorology, the hydrological cycle, the radiative budget, or climate change. Recently, BASEASIA (Biomass-burning Aerosols in South-East Asia: Smoke Impact Assessment) and the 7-SEAS (7- South-East Asian Studies) Dongsha Experiment were conducted during the spring seasons of 2006 and 2010 in northern SEA, respectively, to characterize the chemical, physical, and radiative properties of biomass-burning emissions near the source regions, and assess their effects. This paper provides an overview of results from these two campaigns and related studies collected in this special issue, entitled Observation, modeling and impact studies of biomass burning and pollution in the SE Asian Environment. This volume includes 28 papers, which provide a synopsis of the experiments, regional weatherclimate, chemical characterization of biomass-burning aerosols and related pollutants in source and sink regions, the spatial distribution of air toxics (atmospheric mercury and dioxins) in source and remote areas, a characterization of aerosol physical, optical, and radiative properties, as well as modeling and impact studies. These studies, taken together, provide the first relatively complete dataset of aerosol chemistry and physical observations conducted in the sourcesink region in the northern SEA, with particular emphasis on the marine boundary layer and lower free troposphere (LFT). The data, analysis and modeling included in these papers advance our present knowledge of source characterization of biomass-burning pollutants near the source regions as well as the physical and chemical processes along transport pathways. In addition, we raise key questions to be addressed by a coming deployment during springtime 2013 in northern SEA, named 7-SEASBASELInE (Biomass-burning Aerosols Stratocumulus Environment: Lifecycles and Interactions Experiment). This campaign will include a synergistic approach for further exploring many key atmospheric processes (e.g., complex aerosol-cloud interactions) and impacts of biomass burning on the surface-atmosphere energy budgets during the lifecycles of biomass burning emissions

The Changing Landscape for Stroke\ua0Prevention in AF: Findings From the GLORIA-AF Registry Phase 2

Background GLORIA-AF (Global Registry on Long-Term Oral Antithrombotic Treatment in Patients with Atrial Fibrillation) is a prospective, global registry program describing antithrombotic treatment patterns in patients with newly diagnosed nonvalvular atrial fibrillation at risk of stroke. Phase 2 began when dabigatran, the first non\u2013vitamin K antagonist oral anticoagulant (NOAC), became available. Objectives This study sought to describe phase 2 baseline data and compare these with the pre-NOAC era collected during phase 1. Methods During phase 2, 15,641 consenting patients were enrolled (November 2011 to December 2014); 15,092 were eligible. This pre-specified cross-sectional analysis describes eligible patients\u2019 baseline characteristics. Atrial fibrillation disease characteristics, medical outcomes, and concomitant diseases and medications were collected. Data were analyzed using descriptive statistics. Results Of the total patients, 45.5% were female; median age was 71 (interquartile range: 64, 78) years. Patients were from Europe (47.1%), North America (22.5%), Asia (20.3%), Latin America (6.0%), and the Middle East/Africa (4.0%). Most had high stroke risk (CHA2DS2-VASc [Congestive heart failure, Hypertension, Age  6575 years, Diabetes mellitus, previous Stroke, Vascular disease, Age 65 to 74 years, Sex category] score  652; 86.1%); 13.9% had moderate risk (CHA2DS2-VASc = 1). Overall, 79.9% received oral anticoagulants, of whom 47.6% received NOAC and 32.3% vitamin K antagonists (VKA); 12.1% received antiplatelet agents; 7.8% received no antithrombotic treatment. For comparison, the proportion of phase 1 patients (of N = 1,063 all eligible) prescribed VKA was 32.8%, acetylsalicylic acid 41.7%, and no therapy 20.2%. In Europe in phase 2, treatment with NOAC was more common than VKA (52.3% and 37.8%, respectively); 6.0% of patients received antiplatelet treatment; and 3.8% received no antithrombotic treatment. In North America, 52.1%, 26.2%, and 14.0% of patients received NOAC, VKA, and antiplatelet drugs, respectively; 7.5% received no antithrombotic treatment. NOAC use was less common in Asia (27.7%), where 27.5% of patients received VKA, 25.0% antiplatelet drugs, and 19.8% no antithrombotic treatment. Conclusions The baseline data from GLORIA-AF phase 2 demonstrate that in newly diagnosed nonvalvular atrial fibrillation patients, NOAC have been highly adopted into practice, becoming more frequently prescribed than VKA in Europe and North America. Worldwide, however, a large proportion of patients remain undertreated, particularly in Asia and North America.

Weight Loss and Improvement of Obesity-related Illness Following Laparoscopic Adjustable Gastric Banding Procedure for Morbidly Obese Patients in Taiwan

Laparoscopic adjustable gastric banding (LAGB) is a newly developed minimally invasive surgical procedure for the treatment of morbid obesity. This study was conducted to evaluate body weight loss, surgical complications, and comorbidities after LAGB surgery. Methods: Ninety-one morbidly obese patients (mean age, 31.2 years; mean preoperative weight, 120.8 kg) underwent LAGB in a private Taiwan hospital setting within a comprehensive multidisciplinary bariatric program. Patients were followed up to 36 months. Comorbidities were assessed in 55 patients who completed more than 12 months of follow-up by comparing each comorbid condition before surgery and during follow-up. Results: All procedures were performed laparoscopically with no conversion. Mean operation time was 88.7 ±32.9 minutes. There were no intraoperative or major postoperative complications. Minor complication of stoma stenosis occurred in three (3.3%) patients. At 36 months after surgery, mean body mass index had decreased from 42.7 to 33.9 kg/m2, and mean percentage of excess weight loss was 44.8%. Late complications were as follows: intractable vomiting requiring band removal in one (1.1%) patient, tubing problems requiring revision surgery in four (4.3%), and stoma obstruction in two (2.1%). There was no mortality. Resolution or improvement of comorbidities was significant for hyperglycemia and diabetes-related index, dyslipidemia, abnormal liver function, hyperuricemia, sleep apnea, and arthralgia, but not for hypertension. Conclusion: LAGB provides good weight loss and significant reduction in comorbidities with few minor complications

Anti-neutrophil Cytoplasmic Antibody-associated Pauci-immune Crescentic Glomerulonephritis Complicating Sjögren's Syndrome

Sjögren's syndrome is a chronic autoimmune disease, characterized by specific autoimmune antibodies anti-Ro and anti-La, and it can involve multiple organs, such as the kidneys, lungs, muscles, and nervous system. The most common renal complication of Sjögren's syndrome is tubulointerstitial nephritis, and glomerulonephritis is relatively uncommon. We report the case of an 86-year-old man presenting with recurrent fever, poor appetite, decreased salivary secretion, and body weight loss. Laboratory investigation revealed that serum creatinine was 4.2 mg/dL, proteinuria was 3+, and there was microscopic hematuria. Positive perinuclear anti-neutrophil cytoplasmic antibody, anti-Ro, and anti-La antibodies were detected. Renal biopsy showed crescentic glomerulonephritis with scanty immune complex deposition. The patient was diagnosed with primary Sjögren's syndrome complicated with rapidly progressive glomerulonephritis with positive anti-neutrophil cytoplasmic antibody. Unlike the patients of other case reports, our patient's renal function did not recover after immunosuppressant treatment, and he finally received long-term hemodialysis. Pauci-immune glomerulonephritis is a rare renal complication of Sjögren's syndrome, and progress to renal failure in such patients is possible

Surgical intervention of a giant gastric gastrointestinal stromal tumor following neoadjuvant therapy with imatinib

Gastrointestinal stromal tumors (GISTs) treatment has improved remarkably in recent years. However, giant and unresectable lesions could still be challenging, especially from the surgical aspect. We reported a case of a 44-year-old male patient who complained about abdominal pain and distention. Computed tomography scans, upper GI endoscopy, and tissue biopsy proved the diagnosis of a giant GIST which was considered unresectable. With the aid of neoadjuvant imatinib therapy, the tumor shrank tremendously, and we successfully performed en bloc resection with clean margins. Therefore, we suggested combining imatinib therapy and surgery in managing giant and unresectable GIST lesions
