Authors: RIBEIRO Isabella Lima Arrais , VALENÇA Ana Maria Gondim , BONAN Paulo Rogério Ferreti
Published: January 2016

This article reports the resolution of a case of severe oral mucositis and the treatment protocol that promoted complete remission of the lesions. A male 13-year-old patient with chondroblastic osteosarcoma in the left distal thigh and acute lymphoblastic leukemia undergoing cancer treatment with methotrexate presented with severe oral mucositis. The treatment protocol included the use of 10ml of a mucositis mouthwash and low-level laser therapy. The lesions remitted after five days of gargling with the mucositis mouthwash and two sessions of low-level laser therapy on the lesions. The use of a treatment protocol consisting of a mucositis solution associated with low-level laser therapy effectively resolved a case of severe chemotherapy-induced oral mucositis. The monitoring and treatment of oral mucositis lesions in children and adolescents undergoing chemotherapy are necessary to prevent the patient from suffering from induced comorbidities.
Effect of the action of diamond burs with high speed on the tensile strength of cores cemented with zinc phosphate at different preparation times
Authors: Rodrigues Vanilde Rocha
Published: January 2016

Objective: To know the finishing effect, in order to be able to safely proceed with the cores preparation in the daily clinic, without compromising the prosthetic restoration longevity. Methods: This study used 48 human single-rooted premolars, which after the section of its crowns, were endodontically treated, and its root canal prepared 8 mm deep to receive cores casting in cobalt-chrome alloy. Cementing was made with zinc phosphate and the tensile test performed at different preparation times: G1 - without re-preparation after cementation (control); G2 - re-prepared 24 hours after cementation, and G3 - re-prepared 15 minutes after cementation. Results: Statistical analysis showed no significant difference in the tensile strength values in the different groups (p = 0.233), in other words, the core re-preparation 15 minutes or 24 hours after the cementation caused no significant reduction in tensile strength between the core and the root remaining when using the zinc phosphate cement. Conclusion: The metallic core re-preparation cast 15 minutes or 24 hours after cementation caused no significant reduction in tensile strength between the cast metallic core and the root remaining, although in absolute values there was an important difference.

Objective: To know the vulnerability of the elderly to the HIV infection in the context of preventive practices. Method: Exploratory qualitative study, lead from December 2012 to May 2013, with 37 nursing Coexistence Groups in João Pessoa - Paraiba. The Focus Group was elected as the research technique, and the empirical material obtained was subjected to a Content Analysis Technique, thematic modality. Results: The elderly recognize the importance of preventive practices, but they face difficulties in its use when their emotional relationships with their partners do not favor preventive behavior, resulting in vulnerability. The elderly showed the population groups most vulnerable to HIV and do not recognize themselves as such. Conclusion: The complexity of the various contexts experienced by the elderlies of this study indicate the need for more research that allows advances in the understanding of subjectivity imposed in relations that underlie the aging process and the experience of sexuality in this age group.

Published: January 2016

Objective: to identify situations of pleasure and suffering in the process of training multidisciplinary health resident. Method: qualitative research, developed in the Multiprofessional Residence Program in Health at a university from the south of Brazil. Data was collected in 2013 through focus groups with nine residents, and analyzed according to a thematic analysis. Results: The situations of suffering were stimulated by negative situations undergone by the health workers such as difficulties in participating in other professional training activities, excessive number of activities the residents commit to as health workers, lack of knowledge and hindered integration in the areas of Residency. The situations of pleasure were a result of the multiprofessional activities developed and the resident's larning possibility. Conclusion: The situations of pleasure and suffering identified can help in the planning of institutional actions that contribute to a professional training process and the overall wellbeing of the residents.

Authors: Roque Ariane Thaise Frello , Carraro Telma Elisa
Published: January 2016

Objective: to understand the perceptions of high-risk puerperal women about the hospital environment based on Florence Nightingale's theory. High-risk postpartum period is the period of time when post-partum women care for their babies in the neonatal ICU, and experience high stress levels. Methods: it is a qualitative study with narrative approach based on Florence Nightingale's theory, conducted at a public institution in southern Brazil, from January to March 2010. Seven mothers over 18 years with newborns admitted to the neonatal ICU were the research subjects. Results: the contextualization of their narratives, the caring environment in which they experienced this particular stage in their lives, indicates that high-risk puerperal women seek ties and support. Conclusions: the challenge of spending an indefinite period of time in a strange environment, away from home, with their babies under the care of health professionals, while apart from their relatives, highlights the need for nursing care during this stage.
Niilismo e alegoria em Lira de lixo , de Adriano Scandolara
Authors: Santiago Emmanuel
Published: January 2016

RESUMO Em Lira de lixo , Adriano Scandolara elabora poeticamente uma vivência social típica da modernidade, relacionada à vida num grande centro urbano (no caso, a Curitiba do século XXI). Tal vivência pode ser percebida não apenas na temática desenvolvida nos poemas do autor como também nas determinantes formais de sua poesia. Conjuga-se, então, uma visão niilista da existência, que nega a vida e a história como unidades de sentido, com uma forma fragmentada (alegórica), que rompe com a noção clássica da obra de arte orgânica. A análise segue no sentido de colocar a poesia de Scandolara em constante fricção com o pensamento de Walter Benjamin a respeito da vida moderna e a expressão desta no campo das artes.

Published: January 2016

The electrical conductivity test is a quick, practical and objective test force; however, its effectiveness varies according to the species, quantity of seed, water volumes, soaking temperature, among other factors. The objective of this study was to evaluate the physiological quality of P.moniliformis seeds lots by means of the electrical conductivity test, testing different methodologies. For this, two lots were tested in three quantities of time (25, 50 and 75 seeds) and nine soaking times (2, 4, 6 , 12, 24 , 36, 48, 60 and 72 hours) in three volumes of water (50, 75 and 100 mL) at 25 °C. To evaluate the initial quality of the lots, germination percentage, germination speed index, average time of germination, length and dry mass of seedlings were determined. The use of the electrical conductivity test of P. moniliformis seeds is recommended using 75 seeds in 75 mL of water for 2 hours at 25 °C or seeds in 50 mL distilled water with 50 seeds per 6 hours at 25 °C.

Published: January 2016

Brazilian guava (Psidium guineense Swartz.) is a plant species native from Brazil and present in all Brazilian biomes. This species occurs in the Caatinga biome as a wild fruit that has broad utility and can generate income, as well as provide material for breeding. The objective of this work was to study seed germination of guava accessions collected in two municipalities in Bahia. Seeds imbibition curve was studied. Also, seed germination and seedlings initial growth were evaluated for 44 days on different temperatures (15, 20, 25, 30 and 35 °C), fruit maturation, drying, pre-soaking and priming. Seeds imbibition curve was triphasic in which lag-phase begun after 30 hours imbibition and lasted 256 hours. An effect of guava genotype was observed in seeds physiological quality. Temperatures of 20 and 25 °C were ideal for guava seeds germination. Seeds pre-soaking and priming techniques are feasible to reduce germination time and increase seedling performance.

Published: January 2016

The reactivation of Chagas disease in HIV infected patients presents high mortality and morbidity. We present the case of a female patient with confirmed Chagasic meningoencephalitis as AIDS-defining illness. Interestingly, her TCD4+ lymphocyte cell count was 318 cells/mm3. After two months of induction therapy, one year of maintenance with benznidazol, and early introduction of highly active antiretroviral therapy (HAART), the patient had good clinical, parasitological and radiological evolution. We used a qualitative polymerase chain reaction for the monitoring of T. cruzi parasitemia during and after the treatment. We emphasize the potential value of molecular techniques along with clinical and radiological parameters in the follow-up of patients with Chagas disease and HIV infection. Early introduction of HAART, prolonged induction and maintenance of antiparasitic therapy, and its discontinuation are feasible, in the current management of reactivation of Chagas disease.

Published: January 2016

Anisakiasis and Pseudoterranovosis are human diseases caused by the ingestion of live Anisakidae larvae in raw, undercooked or lightly marinated fish. Larvae were collected from one salted cod sold for human consumption in a Sao Paulo market in 2013. One section of one brownish larva was used for molecular analyses. The partial COX2 gene sequence from the larva had a nucleotide identity of 99.8 % with Pseudoterranova azarasi, which belongs to the Pseudoterranova decipiens species complex. The risk of allergy when consuming dead larvae in salted fish is not well known and should be considered.

Published: January 2016

Resumo: O objetivo deste trabalho foi avaliar o efeito de alturas de pastejo e épocas de dessecação de uma pastagem de Urochloa ruziziensis e da adubação nitrogenada sobre o desempenho da soja. Foram testadas três alturas (15, 35 e 50 cm) de pastejo contínuo da pastagem por bovinos, durante seis meses, além de um piquete sem pastejo, que constituíram quatro experimentos distintos. Em cada experimento, utilizou-se o delineamento de blocos ao acaso, em arranjo de parcelas subdivididas. Nas parcelas principais, foram alocadas quatro épocas de dessecação da pastagem (35, 28, 20 e 8 dias antes da semeadura da soja); e, nas subparcelas, foram realizados dois tratamentos (sem e com 30 kg ha-1 de N, aplicado a lanço na semeadura). O manejo da pastagem de U. ruziziensis a 35 cm de altura confere maior produtividade de grãos de soja cultivada em sucessão à pastagem. Os intervalos de 8 a 35 dias, entre a dessecação da pastagem de U. ruziziensis e a semeadura da soja, não alteram o desempenho agronômico da cultura. Após o manejo da pastagem de U. ruziziensis, a aplicação de 30 kg ha-1 de N à soja, em semeadura, proporciona maior altura de plantas e de inserção da primeira vagem, mas não altera a produtividade de grãos.

Resumo: O objetivo deste trabalho foi avaliar o efeito de diferentes quantidades de palhada sobre o sistema radicular e a produtividade da cana-de-açúcar (Saccharum officinarum), de primeira e segunda soqueiras, em Latossolo Vermelho eutroférrico. Seis tratamentos foram avaliados : 0, 5 (25%), 10 (50%), 15 (75%) e 20 Mg ha-1 (100%) de palhada e cana-queimada, na primeira e segunda soqueiras. Utilizou-se a cana-de-açúcar 'SP80-1816'. Avaliou-se a massa de raízes a 0,45 e 0,75 m de distância da linha de plantio, até 0,60 m de profundidade. Na primeira soqueira, os tratamentos com 50, 75 e 100% de palhada proporcionaram maior massa radicular até 0,20 m de profundidade, em comparação aos tratamentos cana-queimada, 0 e 5 Mg ha-1 (25%) de palhada. Os tratamentos com 50 e 75% de palhada proporcionaram produtividades 43% maiores do que a da cana-queimada (110 Mg ha-1). O tratamento com 10 Mg ha-1 (50%) foi suficiente para proporcionar aumento da massa radicular e da produtividade da cana-de-açúcar. O sistema radicular e a produtividade da cana-de-açúcar são favorecidos pela mudança do sistema de colheita de cana-queimada para o de cana sob palhada.

Published: January 2016

Abstract : The objective of this work was to evaluate the effect of (S)-cis-abscisic acid (S-ABA) application at different ripening stages, in increasing phenolic compounds and color of berry and juice of 'Isabel' grape (Vitis labrusca). The evaluated treatments were: control, without S-ABA application; 400 mg L-1S-ABA applied 7 days before veraison (DBV) + 400 mg L-1S-ABA at 35 days after first application (DAFA); 400 mg L-1S-ABA applied at veraison (V) + 400 mg L-1S-ABA at 35 DAFA; and 400 mg L-1S-ABA applied 7 days after veraison (DAV) + 400 mg L-1S-ABA at 35 DAFA. There was no difference among treatments regarding the physical characteristics of berries and clusters, as well as total polyphenols in berry and juice. However, there was an increase in total anthocyanins in berry and juice with S-ABA application. Colorimetric variables indicated the increase in color of berry treated with S-ABA. Juices produced from grapes treated with S-ABA were more appreciated by tasters. The treatments with 400 mg L-1S-ABA applied 7 days before, during, or 7 days after veraison, combined with an additional application 35 days after the first one, increment total anthocyanin concentration and color of berry and juice of 'Isabel' grape, with better juice acceptance, without affecting total polyphenol concentration.

Resumen Introducción: la deficiencia de antitrombina III hereditaria es una rara enfermedad que afecta al 0.02-0.2% de la población. Puede presentar mayor frecuencia de complicaciones y resultados adversos tanto en la madre como en el feto. Se presenta el manejo obstétrico de dos gestaciones consecutivas en una mujer con deficiencia de antitrombina III. Descripción: en ambos embarazos la madre realiza profilaxis de la enfermedad tromboembólica con heparina de bajo peso molecular para evitar la aparición de esta patología tanto en el embarazo como en el puerperio y mejorar el flujo útero-placen-tario. Con respecto a las complicaciones obstétricas, sólo existe un enlentecimiento del crecimiento fetal que obliga a un control obstétrico estricto. En ambas gestaciones los estudios eco-Doppler están dentro de la normalidad lo que permite una conducta expectante, consiguiendo llegar a término. Discusión: la profilaxis con heparina de bajo peso molecular en las gestantes con esta trombofilia y las intervenciones preventivas de factores de riesgo de enfermedad tromboembólica, junto con un control obstétrico adecuado, ha conseguido evitar la apari-ción de complicaciones derivadas de esta patología en el embarazo y en el puerperio. Por otra parte, el control del crecimiento fetal y el estudio Eco-Doppler han permitido asegurar el bienestar fetal no adelan-tando el parto, consiguiendo partos a término.

Published: January 2016

Abstract Introduction: melanoma is a very aggressive cancer, with increasing incidence, and is currently the fifth most common cancer in men and the sixth most common in women in the United States. Melanoma is not unusual in pregnancy, with an estimated occur-rence rate of 1:1.000. Although not the most common cancer in pregnancy, melanoma is the tumor with the highest incidence ofplacenta and fetus metastases. Description: a 29-year-old lady, 4 weeks after conception underwent resection of an atypical pigmented lesion after a diagnosis of stage T4b melanoma. At 16 weeks she underwent a broad local excision and sentinel lymph node (SLN) biopsy. SLN was evaluated histologically and tested positive for melanoma. A radical axillary lymphadenectomy was performed on the patient without evidence of metas-tasis in any other LN. In the 40th week of pregnancy, labor was induced and a healthy newborn was deli-vered via cesarean. Discussion: melanoma management in pregnancy is more complex and requires multidisciplinary coor-dination, as well as extensive discussion with the patient and her family. We present a case report description in which treatment recommendations are established according to no pregnancy experience.
Performance comparison of biotic indices measuring the ecological status base on soft-bottom macroinvertebrates: a study along the shallow Gomishan lagoon (Southeast Caspian Sea)
Authors: Basatnia Nabee , Hosseini Seyed Abbas , Ghorbani Rasoul , Muniz Pablo
Published: January 2016

Abstract This paper aims to test the suitability of some biotic indices for their application in Southeast Caspian Sea. For this purpose, the ecological quality of the Gomishan lagoon was assessed using three biotic indices (AMBI, BENTIX, BOPA) during summer and autumn 2010. The results from the application of the biotic indices do not highlight a clear distinction between the stations. The results show that two of the indices (AMBI and BENTIX) are very close in terms of diagnosis (good and high) and seem to generally perform better than BOPA. In addition, Principal Component Analysis (PCA) based on abiotic parameters showed clear spatial and temporal differences in environmental variables. However, at this shallow sites with low human pressure and high water residence times, such benthic community composition can be associated with physical stress due to salinity increase and to changes in environmental characteristics, triggered by conventional seasonal variations. Natural variability of transitional waters is a crucial factor for a correct evaluation of the ecological condition of macroinvertebrate communities across the lagoonal system.
Numerical simulations of SAR microwave imaging of the Brazil current surface front
Authors: Macedo Carina Regina de , Lorenzzetti João Antônio
Published: January 2016

Abstract This paper analyzes the hydrodynamic and atmospheric instability modulation mechanisms which influence the Brazilian Current's (BC) thermal front signature in Synthetic Aperture Radar (SAR) images. Simulations were made using the M4S SAR imaging model. Two SAR images of the Brazilian Southeastern Coast depicting the BC's thermal front were selected including a VV (ASAR/Envisat) and a HH polarization (RADARSAT-1) image. Conditions of current shear and divergence were reproduced for the fronts imaged, using in situ (Acoustic Doppler Current Profilers) current velocities. Wind velocity fields were simulated based on QuikSCAT data. Results showed that SAR imaging of the BC front may be influenced both by atmospheric instabilities and hydrodynamic modulations. The first mechanism prevailed on the RADARSAT image and the latter on the ASAR/Envisat image. When atmospheric instabilities prevailed, the contribution of shear and divergence was almost negligible. When hydrodynamic modulations prevailed, a better agreement between the simulated responses and SAR image responses was obtained by inforcing a reduction of 88% in the relaxation rate, and higher divergence values, of the order of 10-4 s-1. Results indicate that, for some specific cases, local increases in shear and divergence may allow the detection of the BC thermal front.

Published: January 2016

Abstract The objective of the present study was to follow the structural modifications of the aortic wall in middle-aged rats submitted to a resistance training protocol for a period of four months. Three groups of 8 animals per group were considered: middle-aged group (MA), old control group (OC) and old trained group (OT). Training consisted in to climb a 1.1-m vertical (80° incline) ladder with weights tied to their tail. Aortic wall structural modifications were studied through light and electron microscopy and morphometry. The mean arterial blood pressure at rest was similar in the three experimental groups (p = .07). At the beginning of the experiment, the OC and OT groups had similar repetition maximums, ranging from 1.6-fold to 1.9-fold the body weight. At the end of the experiment, the repetition maximum of the OT group was 5-fold greater than the body weight (p = .03). The LV weight was 15% larger in the OT group than in the MA group and 12% larger than in the OC group (p = .02). The LV wall thickness of the OT group was significantly larger than that of both, the MA group and the OC group (p = .03). The LV internal diameter in the OT group was significantly smaller than that observed in the MA and OC groups (p = .02). Resistance training diminished the alterations associated with aging improving aortic wall structure by reducing the thickness, normalising the elastic material, the collagen and the smooth muscle cells. Resistance training seems to be a potential treatment for reducing the deleterious effects of aging on the aortic wall.
Vastus lateralis muscle architecture to estimate knee extension moment of older individuals
Authors: Brodt Guilherme Auler , Geremia Jeam Marcel , Melo Mônica de Oliveira , Vaz Marco Aurélio , Loss Jefferson Fagundes
Published: January 2016

Abstract The aim of this study was to compare the knee extension moment of older individuals with the muscle moment estimated through a biomechanical model. This was accomplished by using (1) the specific muscle architecture data of individuals, and (2) the generic muscle architecture available in the literature. The muscle force estimate was determined using a model with the muscle architecture from cadavers and the individual vastus lateralis muscle architecture of sixteen older volunteers. For the muscle moment comparison, all of the volunteers performed maximal voluntary isometric contractions (MVIC) in five different knee extension position angles. The architectural data was acquired using both resonance and ultrasound imaging. Both estimated muscle moments (generic and individual) were higher than the experimental. The architecture of the other vastii may be necessary to make the model more accurate for the older population. Although other factors inherent to ageing, such as co-contractions, fiber type percentage, and passive forces are not considered in the model, they could be responsible for the differences between moments in older people.
A New Generalized Poisson-Lindley Distribution: Applications and Properties
Authors: Bhati Deepesh , Sastry DVS , Qadri PZ Maha
Published: January 2016

A new generalized Poisson Lindley distribution is obtained by compounding Poissondistribution with two parameter generalised Lindley distribution. The new distribution isshown to be unimodal and over dispersed. This distribution has a tendency to accommodate right tail as well as for particular values of parameter the tail tends to zero at a faster rate. Various properties like cumulative distribution function, generating function, Moments etc. are derived. Knowledge about the parameters is obtained through Method of Moments, Maximum Likelihood Method and EM Algorithm. Moreover, an actuarial application in collective risk model is shown by considering the proposed distribution as primary and Exponential and Erlang as secondary distribution. The model is applied to real dataset and found to perform better than competing models.
Restricted graphical log-linear models
Authors: Ramírez-Aldana Ricardo , Eslava-Gómez Guillermina
Published: January 2016

We introduce a new type of graphical log-linear model called restricted graphical log-linear model. This model is obtained by imposing equality restrictions on subsets of main effects and of first-order interactions. These restrictions are obtained through partitions of the variable and first-order interaction sets. The vertices or variables in the same class have the same main effects in all their categories and the first-order interactions in the same class are equal. We study its properties and derive its associated likelihood equations and give some applications. A graphical representation is possible through a coloured graph.

Preliminary findings of finger independency and visual force control in children with DCD
Authors: Oliveira Marcio Alves de
Published: January 2016

Finger independency and visual force control were studied in children with DCD. Five children, 9 to10 years of age, diagnosed with DCD and five age-matched typically developing children were asked to perform two isometric tasks, maximum voluntary force production (MVF) and visual force control (VFC), in seven different finger conditions [Index (I), Middle (M), Ring (R), Little (L) IM, IMR, and IMRL]. For the VFC tasks, the participants were asked to continuously control their finger forces at 20% of the MVF. To examine finger force independency, maximum voluntary force (MVF), force enslaving (FE) and force sharing (FS) values were computed. To analyze the ability of children with DCD to visually control their finger forces, the following performance measures were calculated: rate of force change, initial overshoot, coefficient of variation (CV), root mean square error (RMSe), and inter-trial variability. The results from the MVF task showed that children with DCD as compared with TD children (a) produced similar levels of maximum finger force; (b) demonstrated less finger independency; (c) had similar finger-force sharing patterns. In addition, from the VFC task we found (d) larger performance errors in children with DCD; (e) and lower inter-trial consistency as compared to their TD peers. Our preliminary findings suggest that the impairments in manipulative skills often observed in children with DCD during everyday activities may be related to deficits in finger independency. Additionally we found that children with DCD do not have difficulties in reducing the number of joint/muscle-level degrees of freedom in order to achieve a common motor task.

Published: January 2016

In late pregnancy, maternal insulin resistance occurs to support fetal growth, but little is known about insulin-glucose dynamics close to delivery. This study measured insulin sensitivity in mice in late pregnancy at day 16 (D16) and near term at D19. Nonpregnant (NP) and pregnant mice were assessed for metabolite and hormone concentrations, body composition by DEXA, tissue insulin signaling protein abundance by Western blotting, glucose tolerance and utilization, and insulin sensitivity using acute insulin administration and hyperinsulinemic-euglycemic clamps with [3H]glucose infusion. Whole-body insulin resistance occurred in D16 pregnant dams in association with basal hyperinsulinemia, insulin-resistant endogenous glucose production, and downregulation of several proteins in hepatic and skeletal muscle insulin signaling pathways relative to NP and D19 values. Insulin resistance was less pronounced at D19, with restoration of NP insulin concentrations, improved hepatic insulin sensitivity, and increased abundance of hepatic insulin signaling proteins. At D16, insulin resistance at whole-body, tissue, and molecular levels will favor fetal glucose acquisition, while improved D19 hepatic insulin sensitivity will conserve glucose for maternal use in anticipation of lactation. Tissue sensitivity to insulin, therefore, alters differentially with proximity to delivery in pregnant mice, with implications for human and other species.

OBJECTIVE

We investigated fat distribution and tissue-specific insulin-stimulated glucose uptake (GU) in seven fat compartments (visceral and subcutaneous) and skeletal muscle in morbidly obese patients with (T2D) and without (ND) type 2 diabetes before and 6 months after bariatric surgery.

RESEARCH DESIGN AND METHODS

A total of 23 obese patients (BMI 43.0 ± 3.6 kg/m2; 9 T2D and 14 ND) were recruited from a larger, randomized multicenter SLEEVEPASS study. MRI (for fat distribution) and [18F]-fluorodeoxyglucose PET (for GU) studies were performed for the obese patients before and 6 months postsurgery; 10 lean subjects served as control subjects and were studied once.

RESULTS

At baseline, visceral fat GU was 30 ± 7% of muscle GU in control subjects and 57 ± 5% in obese patients. Visceral and deep subcutaneous fat were more abundant (despite same total fat mass) and less insulin sensitive in T2D than ND; in both, GU was impaired compared with control subjects. Postsurgery, visceral fat mass decreased (∼40%) more than subcutaneous fat (7%). Tissue-specific GU was improved, but not normalized, at all sites in T2D and ND alike. The contribution of visceral fat to whole-body GU was greater in T2D than ND but decreased similarly with surgery. Subcutaneous fat made a fourfold greater contribution to whole-body GU in obese versus lean subjects (15% vs. 4%) both before and after surgery.

CONCLUSIONS

Bariatric surgery leads to sustained weight loss and improves tissue-specific glucose metabolism in morbidly obese patients. We conclude that 1) enhanced visceral fat accumulation is a feature of T2D, 2) severe obesity compromises muscle insulin sensitivity more than fat insulin sensitivity, and 3) fat mass expansion is a sink for plasma glucose.

OBJECTIVE

Treatment of severe hypoglycemia with loss of consciousness or seizure outside of the hospital setting is presently limited to intramuscular glucagon requiring reconstitution immediately prior to injection, a process prone to error or omission. A needle-free intranasal glucagon preparation was compared with intramuscular glucagon for treatment of insulin-induced hypoglycemia.

RESEARCH DESIGN AND METHODS

At eight clinical centers, a randomized crossover noninferiority trial was conducted involving 75 adults with type 1 diabetes (mean age, 33 ± 12 years; median diabetes duration, 18 years) to compare intranasal (3 mg) versus intramuscular (1 mg) glucagon for treatment of hypoglycemia induced by intravenous insulin. Success was defined as an increase in plasma glucose to ≥70 mg/dL or ≥20 mg/dL from the glucose nadir within 30 min after receiving glucagon.

RESULTS

Mean plasma glucose at time of glucagon administration was 48 ± 8 and 49 ± 8 mg/dL at the intranasal and intramuscular visits, respectively. Success criteria were met at all but one intranasal visit and at all intramuscular visits (98.7% vs. 100%; difference 1.3%, upper end of 1-sided 97.5% CI 4.0%). Mean time to success was 16 min for intranasal and 13 min for intramuscular (P < 0.001). Head/facial discomfort was reported during 25% of intranasal and 9% of intramuscular dosing visits; nausea (with or without vomiting) occurred with 35% and 38% of visits, respectively.

CONCLUSIONS

Intranasal glucagon was highly effective in treating insulin-induced hypoglycemia in adults with type 1 diabetes. Although the trial was conducted in a controlled setting, the results are applicable to real-world management of severe hypoglycemia, which occurs owing to excessive therapeutic insulin relative to the impaired or absent endogenous glucagon response.

Although the number of experimental studies investigating the effect of friction stir welding (FSW) parameters on joining properties have increased recently, there are not sufficient numbers of studies on the effect of the stirring tool material in friction stir welding. This study investigated the effect of stirring tool materials on microstructure, mechanical properties and residual stress of joints. Samples of 7075-T651 Al alloys were joined by FSW using uncoated and TiN-coated X210Cr12 alloy steel stirring tools. The welding processes were performed at rotational speeds of 900, 1250 and 1600 rpm and at a welding speed of 60 mm × min−1. Mechanical and metallographic tests were applied to the welded joints and residual stress analysis was performed using the hole drilling method. The best mechanical properties were determined in the welded samples joined by the uncoated tool at a rotational speed of 900 rpm. It was also determined that the TiN-coated tool negatively affected the mechanical and metallurgical properties of the weldements. Moreover, the highest longitudinal residual stresses were specified in the joining performed by the uncoated tool.

Published: January 2016

In this study, Co-based Cr-Mo powder alloy was produced at different pressing temperatures by using hot pressing technique and abrasive wear behaviors of the produced specimens were examined. Produced specimens were exposed to abrasive wear experiment using block on disc wear test device by applying a load of 50 N with 100-mesh SiC abrasive paper. Each specimen was investigated at 25, 50, 75 and 100 m. At the end of the experiment, abrasive wear results of the specimens were determined by calculating their mass losses. Microstructural properties of the specimens which were produced at different pressing temperatures were investigated by optical and SEM examinations and their wear resistances were examined by abrasive wear experiments. Consequently, it was observed that in Co-based Cr–Mo powder alloy produced by hot pressing technique; as sintering temperature increased, size of neck formations between the powder grains increased, porosity decreased and abrasive wear resistance increased.

Iron deficiency anemia is considered as one of the major public health problem in Bangladesh. Cardiac autonomic nerve dysfunction may present in iron deficiency anemia which increases the risk and further complications of this disease. Assessment of heart rate variability (HRV) is a non-invasive technique to evaluate cardiac autonomic nerve function status. To assess the cardiac autonomic nerve function status by heart rate variability analysis, 100 female subjects with iron deficiency anemia aged 20-45 years were included in the study group. For comparison, age and sex matched 100 apparently healthy female were selected as control. The HRV parameters were recorded by a 4 active channels, Polyrite-D. Mean resting pulse rate, LF power, LF norm and LF/HF were significantly (p <0.0001) higher and total power, HF power, HF norm were significantly (p <0.0001) lower in subjects with iron deficiency anemia in comparison to those of control group. This study concludes that cardiac parasympathetic activity was reduced in female with iron deficiency anemia.Bangladesh Med J. 2014 Sep; 43 (3): 125-129

Non-cirrhotic portal hypertension (NCPH) is a heterogeneous group of liver disorders of vascular origin, leading to portal hypertension (PHTN) in the absence of cirrhosis.The lesions are generallyvascular, either in the portal vein, its branches or in the peri-sinusoidal area. The majority of diseases included in the category of NCPH are well-characterized disease entities where PHTN is a late manifestation. Two diseases that present only with features of PHTN and are common in developing countries are non-cirrhotic portal fibrosis (NCPF) and extrahepatic portal vein obstruction (EHPVO). Non-cirrhotic portal fibrosis is a syndrome of obscure etiology, characterized by obliterative-portovenopathy leading to PHT, massive splenomegaly and well-tolerated episodes of variceal bleeding in young adults from low socioeconomic backgrounds, having near normal hepatic functions. In some parts of the world, NCPFis called idiopathic portal hypertension in Japan or hepatoportalsclerosisin USA. Because 8595% of patient with NCPF and EHPVO present with variceal bleeding, treatment involves management with endoscopic sclerotherapy (EST) or variceal ligation (EVL). These therapies are effective in approximately 9095% of patients. Gastric varices are another common cause of upper gastrointestinal bleeding in these patients and these can be managed with cyanoacrylate glue injection or surgery. The prognosis of patients with NCPF is good and 5 years survival in patients in whom variceal bleeding can be controlled has been reported to be approximately 95100%.Bangladesh Med J. 2014 Sep; 43 (3): 170-176

Published: January 2016

Phase change materials (PCM) in the construction industry became attractive because of several interesting attributes, such as thermo-physical parameters, open air atmospheric condition usage, cost and the duty structure requirement. Thermal performance optimization of PCMs in terms of proficient storage of a large amount of heat or cold in a finite volume remains a challenging task. Implementation of PCMs in buildings to achieve thermal comfort for a specific climatic condition in Iraq is our main focus. From this standpoint, the present paper reports the experimental and numerical results on the lowering of heat flux inside a residential building using PCM, which is composed of oil (40%) and wax (60%). This PCM (paraffin), being plentiful and cost-effective, is extracted locally from waste petroleum products in Iraq. Experiments are performed with two rooms of identical internal dimensions in the presence and absence of PCM. A two-dimensional numerical transient heat transfer model is developed and solved using the finite difference method. A relatively simple geometry is chosen to initially verify the numerical solution procedure by incorporating in the computer program two-dimensional elliptic flows. It is demonstrated that the heat flux inside the room containing PCM is remarkably lower than the one devoid of PCM.
Assessing the Environmental Sustainability of Electricity Generation in Turkey on a Life Cycle Basis
Authors: Atilgan Burcin , Azapagic Adisa
Published: January 2016

Turkey’s electricity mix is dominated by fossil fuels, but the country has ambitious future targets for renewable and nuclear energy. At present, environmental impacts of electricity generation in Turkey are unknown so this paper represents a first attempt to fill this knowledge gap. Taking a life cycle approach, the study considers eleven impacts from electricity generation over the period 1990–2014. All 516 power plants currently operational in Turkey are assessed: lignite, hard coal, natural gas, hydro, onshore wind and geothermal. The results show that the annual impacts from electricity have been going up steadily over the period, increasing by 2–9 times, with the global warming potential being higher by a factor of five. This is due to a four-fold increase in electricity demand and a growing share of fossil fuels. The impact trends per unit of electricity generated differ from those for the annual impacts, with only four impacts being higher today than in 1990, including the global warming potential. Most other impacts are lower from 35% to two times. These findings demonstrate the need for diversifying the electricity mix by increasing the share of domestically-abundant renewable resources, such as geothermal, wind, and solar energy.
