Published: March 2016

Background:Glass-ionomer cements perform a protective effect on the dentin-pulp complex considering the F ions release and chemical bonding to the dental structures. On the other hand, those materials have poor physic-mechanical properties in comparison with the restorative resin composite. The main aim of this work was to evaluate the influence of zirconia and/or alumina fillers on the microstructure and strength of a resin modified glass-ionomer cement after thermal cycling.Methods:Anin vitroexperimental study was carried out on 9 groups (n= 10) of cylindrical samples (6 x 4 mm) made from resin modified glass-ionomer (Vitremer, 3M, USA) with different contents of alumina and/or zirconia fillers. A nano-hybrid resin composite was tested as a control group. Samples were mechanically characterized by axial compressive tests and electron scanning microscopy (SEM) coupled to energy dispersive X-ray spectrophotometry (EDS), before and after thermal cycling. Thermal cycling procedures were performed at 3000, 6000 and 10000 cycles in Fusayama´s artificial saliva at 5 and 60oC.Results:An improvement of compressive strength was noticed on glass-ionomer reinforced with alumina fillers in comparison with the commercial glass ionomer. SEM images revealed the morphology and distribution of alumina or zirconia in the microstructure of glass-ionomers. Also, defects such as cracks and pores were detected on the glass-ionomer cements. The materials tested were not affected by thermal cycling in artificial saliva.Conclusion:Addition of inorganic particles at nano-scale such as alumina can increase the mechanical properties of glass-ionomer cements. However, the presence of cracks and pores present in glass-ionomer can negatively affect the mechanical properties of the material because they are areas of stress concentration.
Value-Relevance of Corporate Social Responsibility: Evidence from Short Selling
Authors: Jain Archana , Jain Pankaj K. , Rezaee Zabihollah 
Published: March 2016

ABSTRACT
We examine whether short sellers, as informed investors, take into consideration corporate social responsibility (CSR) performance and disclosure in the areas of environmental, social, and governance (ESG) sustainability in making investment decisions. We find that firms' market value and future financial performance, measured by price per share, return on equity, and return on assets, are lower, whereas operating risk, measured by the standard deviation of return on equity and the standard deviation of return on assets, is higher for firms with low composite ESG scores. We detect a negative association between ESG scores and short selling, indicating that short sellers avoid firms with high ESG scores and tend to target firms with low ESG scores. We conclude that investors consider firms' ESG scores as value relevant in making investment decisions and thus management should integrate CSR into strategic decisions and corporate reporting.

Background Functional endoscopic sinus surgery (FESS) is considered to be the standard procedure for chronic rhinosinusitis with nasal polyps (CRSwNP). However, for CRSwNP that accompanies asthma, the results are not satisfying. Extensive endoscopic sinus surgery (EESS) aimed at reducing the inflammatory load has been indicated as a viable option for refractory chronic rhinosinusitis. Objective To evaluate the clinical outcomes and safety of EESS (middle turbinate and superior turbinate resection and total ethmoidectomy) for patients with CRSwNP and with asthma. Methods This was a prospective, single-institute cohort study conducted in a tertiary teaching hospital. Patients with CRSwNP and with asthma who were proceeding to surgery were enrolled. There were 23 patients in the EESS group and 24 patients in the FESS group. The preoperative disease severity was evaluated by the visual analog scale (VAS), Lund-Kennedy (L-K) endoscopy score, computed tomography Lund-Mackay score, asthma control test (ACT), and pulmonary function test. Clinical outcomes were comparatively evaluated between the two groups after a 1-year follow-up by using the VAS score, the postoperative endoscopic score (E score), L-K score, ACT score, and pulmonary function test. Results The disease severity (general VAS score, endoscopic L-K score, computed tomography score, ACT score) showed no significant differences between the two groups before surgery (p > 0.05). One year after surgery, both groups achieved significant improvement in the VAS score and endoscopic L-K score. The EESS group showed better improvement in the olfactory VAS score and E score compared with the FESS group (mean [standard deviation] change of olfactory VAS, 6.00 ∓ 3.67 versus 3.30 ∓ 3.44, p = 0.015; mean [standard deviation] E score, 0.31 ∓ 0.18 versus 0.66 ∓ 0.26, p < 0.001). No significant differences were found in the change of general nasal symptom VAS score, other individual VAS scores (nasal congestion, discharge, headache and/or facial pain), L-K score, ACT score, and pulmonary function between the two groups (p > 0.05). Conclusion EESS for patients with CRSwNP and with asthma may help to improve the subjective olfaction and endoscopic appearance.

Published: March 2016

Background Dry eye is characterized by decreased tear production and/or increased evaporation rates of the tear film barrier. Allergic rhinitis is an inflammatory disease that develops through immunoglobulin E in the rhino ocular mucosa due to allergens. To investigate the prevalence of allergic rhinitis symptoms and positive skin-prick test results in patients with dry eye. Methods This is a case-control study. The study included 57 patients with dry eye and 48 healthy subjects. The prevalence of allergic symptoms and skin-prick test results were assessed and compared with the control group. Results With regard to positive reactions to allergens in skin-prick tests, Dermatophagoides pteronyssinus allergy (p = 0.0003), Dermatophagoides farinae allergy (p = 0.0003), grass-mix allergy (p = 0.049), Salicaces allergy (p = 0.006), and Compositae allergy (p = 0.019) were significantly observed to be higher in the group with dry eye. Nasal obstruction (p = 0.027), discharge (p = 0.0001), sneeze (p = 0.0003), itching (p = 0.0001), and postnasal drainage (p = 0.001) symptoms were observed to be significantly higher in the group with dry eye. Conclusions Our study revealed that there was a significant association between dry eye and allergic rhinitis with positive skin-prick test results. There may be a possible link between dry eye and allergy.

Published: March 2016

Background MUC5AC, a major secreted mucin, is increased in chronic inflammatory airway disease. Spleen tyrosine kinase (SYK) is a mediator, which acts as an important regulator of intracellular signal transduction in the inflammatory response. SYK was originally identified in hematopoietic cells, and its expression in some nonhematopoietic cells, including respiratory epithelial cells, was recently demonstrated. However, the effects of SYK on mucin secretion in human airway epithelial cells have not been studied. The objective of this study was to investigate the effect and brief signaling pathways of SYK on MUC5AC expression in human airway epithelial cells. Methods In mucin-producing human NCI-H292 cells and primary cultures of human nasal epithelial cells, the effects and signaling pathways of SYK on MUC5AC expression were investigated by reverse transcriptase–polymerase chain reaction, real-time polymerase chain reaction, enzyme immunoassay, and immunoblot analysis with several specific inhibitors and small interfering RNA (siRNA). Results SYK induced MUC5AC expression. SYK activated significant phosphorylation of extracellular signal-related kinase (ERK)1/2 and p38 mitogen-activated protein kinase (MAPK) signaling pathways. SYK-induced MUC5AC expression was significantly attenuated by pretreatment with U0126 (ERK1/2 MAPK inhibitor) and SB203580 (p38 MAPK inhibitor). In addition, the knockdown of ERK2 and p38 MAPK by ERK2 and p38 MAPK siRNA significantly blocked SYK-induced MUC5AC expression. Conclusion These results indicated that SYK increased MUC5AC expression via ERK2 and p38 MAPK signaling pathways in human airway epithelial cells.

Published: March 2016

Background Sinonasal inverted papilloma (SNIP), classically, is a unilateral benign tumor of the nasal lateral wall. Numerous variations have been observed, depending on location, bilateral presentation, or association with nasal polyposis. Objective The aim of this work was to describe atypical presentations of SNIPs with their management specificities and to assess their influence on the recurrence rate in a large case series. Methods A retrospective single center study of 110 patients treated for SNIP. Atypical inverted papillomas were identified according to the following criteria: (1) unusual location (frontal, posterior, anterior), (2) bilateral involvement, and (3) association with nasal polyposis. Surgical management was detailed, and the influence of each atypical group on recurrence was assessed by using Kaplan-Meier survival curves and the log-rank test. Results Distribution of atypical presentations was as follows: frontal sinus localization (10.9%); posterior localization, including sphenoid sinus (9%); nasal anterior localization (3.6%); bilateral involvement (3.6%); and nasal polyposis association (10%). The surgical approach was endoscopic (74.5%), external (5.5%), or combined endoscopic and external (20%). Except for nasal anterior localization, all the groups were associated with a higher recurrence rate, without reaching statistical significance. Conclusion Recurrence rates for these atypical presentations arise from their specific surgical challenges. The choice of the surgical technique is guided by tumor location and extension, and by the surgeon's experience; the main objective is a complete resection. The endoscopic endonasal approach is the most frequent procedure.

Background Depression in patients with chronic rhinosinusitis (CRS) is underdiagnosed but significantly impacts treatment outcomes and health care utilization. Objective To compare undiagnosed depression in a CRS cohort with a healthy, non-CRS control cohort. Methods A case-control study of patients with symptomatic CRS and a non-CRS control cohort was performed. Demographic and comorbidity factors were correlated to depression-specific outcomes by using the Beck Depression Inventory II (BDI). Results We enrolled 42 patients with CRS and 88 control patients with no history of CRS. Physician-diagnosed depression was equivalent in CRS and control patients (6% and 9%, respectively). BDI-detected depression was higher among patients with CRS compared with controls (31% versus 14.8%, respectively; p = 0.031). BDI scores were higher in patients with CRS even when controlling for comorbid asthma, allergy, and aspirin sensitivity. When examined by polyp status, the patients without polyps had more depression than did the controls (38% versus 14.8%; p = 0.048). The somatic subscale scores of the BDI were worse in patients with CRS (p = 0.004), whereas the cognitive subscale trended toward significance (p = 0.081). Conclusion Depression may be more common in CRS than previously recognized, especially in patients without polyps. Somatic subscale scores of the BDI are increased in CRS and may impact future treatment outcomes.

Published: March 2016

Background Perioperative antibiotics are commonly used in endoscopic skull base surgeries as prophylaxis for infectious complications, e.g., meningitis. The role of perioperative prophylactic antibiotics in endoscopic sinus surgery is unclear, and the routine use of prophylactic antibiotics in endoscopic skull base surgery is also highly debated. Currently, there is no formal recommendation for perioperative antibiotic use in skull base surgery, and regimens vary greatly from one institution to the next. Objective To assess perioperative antibiotics as prophylaxis against infectious complications in patients who underwent endoscopic skull base surgery. Data Sources PubMed, Ovid EMBASE, and the Cochrane Library. Methods A systematic review that examined perioperative antibiotic use in endoscopic skull base and craniofacial surgeries was conducted. Inclusion criteria were prospective or retrospective study design and clinical trials related to the use of antibiotics within 30 days of skull base surgery. End points included infectious complications such as (1) meningitis and (2) sinusitis. Results A total of 2543 articles were identified by the initial search, and 5 articles met inclusion criteria. The five eligible trials were all observational and involved different types of skull base surgical procedures and antibiotic regimens. Conclusions Despite institutional variability in antibiotic regimens, meningitis rarely occurs after skull base procedures and seems to be encountered most frequently in open craniofacial surgeries. A systematic review revealed a limited number of published studies, all observational in study design, which precluded a formal meta-analysis. A novel large-scale randomized-controlled clinical trial is needed to evaluate antibiotic selection and need in endoscopic skull base surgery.
Hydropower Development: Before and After 1992
Authors: Shrestha Ratna Sansar 
Published: March 2016

Hydropower Development Policy promulgated in 1992 by Government of Nepal (GoN) heralded domestic and foreign private investment in hydropower projects, which was instrumental in adding 255,647 MW to the system with the investment of US$ 493 million in a period of 23 years. While, public sector succeeded to add only 238.6 MW during the same period; thus adding a total of 489.14 MW to the system by public and private sectors. As cumulative total installed capacity of projects implemented prior to it in eight decades from 1911 through 1991 was only 239.33 MW, it manifests successful implementation of the policy with resultant mobilization of private investment.Only 9th five-year plan period (1997-2002) succeeded to achieve 91% of the target set for the period resulting in mismatch in the growth of demand and supply; consequently load shedding. The reasons behind the failure need an in-depth analysis and critique of the policy and improvement thereof. HYDRO Nepal Journal of Water Energy and EnvironmentVolume- 18, 2016, JanuaryPage -16 to 21
Fishing Tourism can Support Fisher’s Livelihood and Fish Conservation in Nepal: A Value Chain Analysis
Authors: Gurung Tek Bahadur , Thing Amar 
Published: March 2016

Fishing tourism of recreational fisheries is a multibillion dollar outdoor activity. The fishing tourism in Nepal is yet to be systematized. Focusing on this need, the present paper attempts to pioneer how recreational fisheries in Nepal could be useful having commendable world renounced fish resources, luring pristine and suitable scenic landscapes for promoting fishing tourism. It is argued that fishing tourism should be systematically regularized and practiced in close collaboration with traditional ethnic fisher communities. Considering the potentiality, we elucidate the result of value chain analysis, arguing that promotion and streamlining of fishing tourism along with the traditional fishers could generate immense livelihood opportunities for resilience along with fish conservation. The value chain analysis showed that livelihood of fishers communities are likely to be enhanced by involving in fishing based tourism support services with fewer fishing activities, which in turn could be supportive to fish conservation. The present modality of promoting and systematizing fishing tourism might have implication to address the issues of poverty alleviation and resilience to fish conservation in many developing countries having similar socio-economic and agro ecological setups in Nepal.

Published: March 2016

Objective.To determine the consequences of disregarding first-degree relatives with psoriasis (FRP) as a classification criterion in juvenile idiopathic arthritis (JIA).Methods.Criteria were examined in children from a prospective cohort with unclassified and psoriatic JIA.Results.FRP was the most common reason children were unclassified (57/85, 67%); all 57 children could be classified if FRP were disregarded as an exclusion criterion. FRP was a necessary inclusion criterion to classify 11/77 (14.3%) children with psoriatic JIA.Conclusion.Eliminating FRP as an exclusion criterion, but keeping it as an inclusion criterion in psoriatic JIA simplifies classification, though it is unclear whether the resulting classification would be better.
