Published: December 2019

Background

Burnout (BO), a critical syndrome particularly for nurses in health care settings, substantially affects their physical and psychological status, the institute’s well-being, and indirectly, patient outcomes. However, objectively classifying BO levels has not been defined and noticed in the literature.

Objective

The aim of this study is to build a model using the convolutional neural network (CNN) to develop an app for automatic detection and classification of nurse BO using the Maslach Burnout Inventory–Human Services Survey (MBI-HSS) to help assess nurse BO at an earlier stage.

Methods

We recruited 1002 nurses working in a medical center in Taiwan to complete the Chinese version of the 20-item MBI-HSS in August 2016. The k-mean and CNN were used as unsupervised and supervised learnings for dividing nurses into two classes (n=531 and n=471 of suspicious BO+ and BO−, respectively) and building a BO predictive model to estimate 38 parameters. Data were separated into training and testing sets in a proportion 70%:30%, and the former was used to predict the latter. We calculated the sensitivity, specificity, and receiver operating characteristic curve (area under the curve) across studies for comparison. An app predicting respondent BO was developed involving the model’s 38 estimated parameters for a website assessment.

Results

We observed that (1) the 20-item model yields a higher accuracy rate (0.95) with an area under the curve of 0.97 (95% CI 0.94-0.95) based on the 1002 cases, (2) the scheme named matching personal response to adapt for the correct classification in model drives the prior model’s predictive accuracy at 100%, (3) the 700-case training set with 0.96 accuracy predicts the 302-case testing set reaching an accuracy of 0.91, and (4) an available MBI-HSS app for nurses predicting BO was successfully developed and demonstrated in this study.

Conclusions

The 20-item model with the 38 parameters estimated by using CNN for improving the accuracy of nurse BO has been particularly demonstrated in Excel (Microsoft Corp). An app developed for helping nurses to self-assess job BO at an early stage is required for application in the future.

Published: December 2019

BACKGROUND

Knowledge graph embedding is an effective semantic representation method for entities and relations in knowledge graphs. Several translation-based algorithms, including TransE, TransH, TransR, TransD, and TranSparse, have been proposed to learn effective embedding vectors from typical knowledge graphs in which the relations between head and tail entities are deterministic. However, in medical knowledge graphs, the relations between head and tail entities are inherently probabilistic. This difference introduces a challenge in embedding medical knowledge graphs.

OBJECTIVE

We aimed to address the challenge of how to learn the probability values of triplets into representation vectors by making enhancements to existing TransX (where X is E, H, R, D, or Sparse) algorithms, including the following: (1) constructing a mapping function between the score value and the probability, and (2) introducing probability-based loss of triplets into the original margin-based loss function.

METHODS

We performed the proposed PrTransX algorithm on a medical knowledge graph that we built from large-scale real-world electronic medical records data. We evaluated the embeddings using link prediction task.

RESULTS

Compared with the corresponding TransX algorithms, the proposed PrTransX performed better than the TransX model in all evaluation indicators, achieving a higher proportion of corrected entities ranked in the top 10 and normalized discounted cumulative gain of the top 10 predicted tail entities, and lower mean rank.

CONCLUSIONS

The proposed PrTransX successfully incorporated the uncertainty of the knowledge triplets into the embedding vectors.

Published: December 2019

Poly(N-vinylcaprolactam) (PNVCL) offers superior characteristics as a thermoresponsive polymer for various potential applications. An attractive procedure, namely in-situ polymerization, was used to prepare NVCL/clay nanocomposite in different clay ratios. Organo-modified clay as C20 and B30 were employed in a range between 1–5% based on weight. Thermogravimetric analysis (TGA) and Fourier transform infrared spectroscopy (FTIR) were used to study thermal decomposition and to assess bond conversion during polymerization of the nanocomposite. This research was conducted to study PNVCL characteristics with the addition of clay as a nanocomposite. The stretch mode of the carboxylic group (C=O) and (C=C) was present in the band range about ~1635 cm–1 for the C20, but it was ranging between 1640 to 1664 cm–1 for the B30 of the nanocomposite. It was observed that the decomposition was different for each type of organoclay and the temperature peaked at 30 to 800 °C, to measure the degradation points at 5, 10, and 50%. Comparison results for FTIR and TGA showed that the best nanocomposite was found in the C20 (3%) case.

Published: December 2019

Noodles is an easy-to-serve food product and widely consumed. The weakness of the noodle is in its hard texture, less elastic and easily broken, so it requires the addition of gelling agent for texture improvement. Gelatin is a gelling agent that can be extracted from fish scales. The addition of gelatin from scales of fish that were caught from different habitat (fresh, brackish, and sea) might affects the characteristics of the dried noodles. This study aimed to determine the effect of gelatin prepared from the scales of tilapia, milkfish and sulphur goatfish on the characteristics of dry noodles.The research method was experimental laboratories using a Completely Randomized Design (RAL) with one factor which was gelatin from the difference fish scales (tilapia, milkfish, and sulphur goatfish). The parameters that were observed include protein content, tensile strength, water content, and hedonic analysis (appearance, smell, taste, and texture). The results show that the addition of tilapia, milkfish and sulphur goatfish scales gelatin significantly affected protein levels, tensile strength, moisture content and hedonic analysis of dried noodles. Dry noodles with the addition of gelatin scales of sulphur goatfish were not significantly different from milkfish gelatin, meanwhile dry noodles with the addition of tilapia scales gelatin shows a significant different from the control. Hedonic scores on a scale of 1 to 5 for dry noodles with fish scales gelatin and controls resulted to the appearance, aroma, taste, and texture values which were favored by panelists. These results indicate that the addition of fish scales gelatin produces characteristics of dry noodles that are suitable for consumption according to SNI 8217.2015.

Published: December 2019

Shrimp farming has been introduced since the mid-1980s at the southern coast of Daerah Istimewa Yogyakarta (DIY). However, the industry was not well growing in the initial stage. The new shrimp development project also promoted in the early of 2000s, particularly in Jangkaran Village, Subdistrict of Temon, Kulon Progo District and Poncosari Village, Subdistrict of Srandakan, Bantul District, but many of shrimp farms fail because of shrimp diseases, lack of capital to recover and shrimp farming experiences. Recently, the shrimp culture industry experienced rapid expansion along the coast of the two districts. This study aimed to determine the profile and growing of shrimp farming at the southern coast of DIY and to identify the technical aspects, social, and economic indicators of sustainable shrimp culture in the less favorable areas. To identify the sustainability of current shrimp culture, the study develop four indicators consist of technical indicators (6 sub-indicators), economic indicators (9 sub-indicators), social indicators (7 sub-indicators), and environmental indicators (8 sub-indicator). The study was conducted during March to October 2014 by using a combination of literature study and survey at two selected villages: Jangkaran and Poncosari Villages. The total 82 respondents were interviewed; consist of shrimp farmers, coastal communities, community leaders, and local government. The study showed that the rapid growing of shrimp farming were caused by several factors, among others: (1) the existence of technological innovation in shrimp farming in the sandy soil areas, particularly the lower cost in the pond investment and the more easier of seawater collecting; (2) high price and market opportunities of the commodity; and (3) changes in the physical environment due to the threat of coastal erosion which damage the fisher livelihood, thus demanding adaptation strategies. Shrimp farmer in average managed 2,138 m2 and implemented intensive to super intensive cultivation technology, with an average stocking density of 144 shrimp/m2. Production per year in average reaches 25.9 ton/ha and generating revenue of IDR286.544.232 per year. The total cost of production is estimated at IDR210.590.175 per year, and generated a net profit of IDR75.954.057 per year. The perception based indicator of sustainability showed the environmental related issues were in average have a low value. Thus, environmental regulation of aquaculture is an important aspect to be considered in promoting sustainable development of shrimp farming at the southern coast of the province.

Authors: ERTEKİN Yusuf Haydar , ARIKAN Sedat , KARABOGA İhsan
Published: December 2019

Introduction: To investigate the effect
of ozone (O3) therapy on cornea subjected to systemically used high dose
methylprednisolone (MP) in a rabbit model.

Methods:  Twenty-four New Zealand White adult male
rabbits were randomly divided into three equal groups as containing eight
animals. The first group (n = 8) was used as the control group and nothing was
applied to them, whereas the other 2 groups named as steroid groups were
subjected to IM methylprednisolone injection at a dose of 20 mg/kg/day for
three days. After three days of MP administration, only the third group was
treated with 50-µg/mL O3 (20 mL O3) through the rectal insufflation for 14
sessions. The histopathological examination of corneas of three groups were
made, and they were also assessed regarding the expression of hypoxia-inducible
factor-1 α (HIF-1α).

Results: It was determined that systemically
administered high dose MP caused erosion and necrosis in corneal epithelium and
stromal disintegrations in corneal stroma in steroid groups (Group 2 and Group
3). In the MP + O3 group (Group 3), the histopathological findings were mild.
The expression of HIF1-α in the cornea of Group1 (control group), Group 2 (MP),
and Group 3 (MP-O3) was measured as, 17.9±9.6%, 3.1±1.0% and 6.4±1.9% respectively.

Conclusions: MP and MP-O3 therapy decreased HIF-1a expression in rabbit cornea in
both intervention groups. Between these two groups, HIF-1α expression remained
relatively high in the MP-O3 group than in the MP group alone.

Authors: Sarwar Jawad , Hasnain Arshmah , Abbas Ahmed , Kakosimos Konstantinos
Published: December 2019

In this work, a novel design of a concentrated photovoltaic system with thermal management using phase change material is analyzed. The novelty lies in utilizing two mono-facial photovoltaic cells, installing one on upper side of the receiver to receive non-concentrated sunlight and installing another photovoltaic cell on bottom side to receive concentrated sunlight. An RT47 (melting range of 41-48?) phase change material enclosed in an aluminum containment regulates the temperature of the system. Parabolic trough concentrator is used to focus sunlight on the bottom photovoltaic cell with a concentration ratio of 25. A finite volume based coupled thermal, electrical and optical model is developed and the system is analyzed for environmental conditions of Doha, Qatar. Temperature regulation and electrical power output of upper photovoltaic cell and bottom concentrated photovoltaic cell of proposed design are compared to a conventional flat plate system. Analysis is made for one day of each month of a year. It is found that the proposed design maintains the temperature below 85? for all months of a year. The performance of the proposed system is comparable to the conventional flat plate system and excels it with power production in the range of ?4.7% and +21.7%.

Published: December 2019

Epistaxis is one of the most common complications of nasotracheal intubation and can be life-threatening. However, there is little discussion in the current literature on the acute management of massive epistaxis after nasotracheal extubation. This is a report of 2 patients who experienced severe unanticipated nasal bleeding immediately after extubation, 1 after a surgical procedure for oral cancer and another after restorative dental treatment. In both cases the significant epistaxis was managed successfully with a Foley balloon catheter used to pack the posterior nasal cavity. The Foley catheter technique may be useful for managing and arresting sudden postextubation epistaxis.

Increase in life expectancy is among the most significant achievements of modern medicine. Currently, the majority of patients are elderly, being characterised by multimorbidity and frailty. Sarcopenia, a progressive and generalized loss of skeletal muscle mass and strength, is associated with a reduced quality of life and high risk of adverse outcomes including disability and death in these patients. Age-related neuromuscular degeneration, decline of circulating anabolic hormones, chronic inflammation and oxidative stress considerably affect the development of sarcopenia. In addition, low intake of proteins and carbohydrates along with a decrease in physical activity also affect muscular homeostasis. Being combined with obesity, osteopenia/osteoporosis, and vitamin D deficiency, sarcopenia worsens the prognosis of the patient in terms of life expectancy. In this review, we discuss the current advances in epidemiology, pathophysiology, and diagnosis of sarcopenia.

Aim. To develop a tool for the prediction of perinatal complications in pregnant women with gestational diabetes utilizing conventional and ultrasound markers of diabetic fetopathy.

Materials and Methods. We analyzed 128 case histories of women who suffered from gestational diabetes. Among their newborns, 35 had clinical manifestations of maternal hyperglycemia (birth weight > 90th percentile, neonatal hyperglycemia, respiratory distress syndrome, and neonatal jaundice) while 74 were free of the indicated signs and symptoms.

Results. Risk factors of maternal hyperglycemia manifestations in neonates included family history of diabetes mellitus type 2, obesity, and pre-eclampsia. Maternal hyperglycemia was significantly associated with the higher risk of adverse perinatal outcomes. A combination of ≥ 4 ultrasound оценке markers of a diabetic fetopathy permitted the diagnosis of the fetal macrosomia. Conclusion. Ultrasound markers of diabetic fetopathy have limited sensitivity in the prediction of perinatal complications after gestational diabetes.

Results. Enterobacteriaceae spp., Enterococcaceae spp. and Staphylococcaceae spp. were respectively isolated from placentas of 24 (37.5%), 19 (29.7%), and 19 (29.7%) women with placental microbial colonization. Candida albicans was isolated in 2 (3.1%) cases. All placentas excised from women without placental microbial colonization were sterile. Vaginal delivery occurred in 61 (95.3%) women with placental microbial colonization but only in 24 (37.5%) women without (p = 0.001). Subinvolution was revealed in 10 (15.6%) and 4 (6.3%) (р = 0.09), lochiometra was found in 4 (6.3%) and 2 (3.1%) (р = 0.409), and wound infections were observed in 5 (7.8%) and 1 (1.6%) (p = 0.095) women with or without placental microbial colonization, respectively. Therefore, prevalence of postpartum complications did not differ significantly between the groups. Placental inflammation was detected in 27(42.2%) and 14 (21.9%) (p = 0.014) patients with or without placental microbial colonization, respectively.

Conclusions. Placental inflammation is associated with microbial colonization which is more common in women who undergo vaginal delivery.

Aim: To study the level of thyroid-stimulating and thyroid hormones in pregnant women with obesity and their newborns.

Materials and Methods. We consecutively recruited 40 pregnant women and their newborns. Blood sampling in pregnant women was carried out at the end of the third trimester 12 hours after the last meal while in newborns it was conducted immediately after birth. Measurement of serum thyroid-stimulating hormone, thyroxine, triiodothyronine, and free thyroxine was performed using chemiluminescent immunoassay.

Results. Thyroid disease was significantly more common in pregnant women with obesity. Clinical and latent hypothyroidism in obese pregnant women was observed 1.5-fold more frequently as compared with those having normal body weight. In keeping with these findings, goiter and elevated thyroxine were also more common in obese pregnant women. Newborns from obese women were more often characterized by a transient hypothyroidism in combination with an augmented thyroid-stimulating hormone.

Conclusion. Levels of thyroid-stimulating and thyroid hormones in obese pregnant women and their newborns significantly differ from the patients with normal body weight.

Aim.To identify associations of mtDNA polymorphisms with sudden cardiac death.

Materials and Methods.DNA was isolated from the cardiac tissue excised during the autopsy from individuals who died from sudden cardiac death (n = 260). The frequencies of the most common European mtDNA haplogroups (H, U, T and J) were determined using restriction fragment length polymorphism analysis. In addition, we performed a comparative analysis using previously published data on mtDNA polymorphisms in the West Siberian population.

Results.The distribution of mtDNA haplogroups in the patients who died from sudden cardiac death was similar as in the general population: 40% for haplogroup H, 23% for haplogroup U, 12% for haplogroup T and 6.5% for haplogroup J. We found no significant differences regarding the frequency of mtDNA haplogroups in individuals who died from sudden cardiac death and the population level.

Conclusion.We discovered no associations of H, U, T, and J mtDNA haplogroups with sudden cardiac death. These results indicate the necessity of a detailed analysis of mitochondrial genome to determine mtDNA variants associated with sudden cardiac death.

Aim. Immunoprevention represents a well-established tool to prevent and eliminate life-threatening infectious diseases. However, low adherence in the population is a major obstacle to achieve the full coverage of preventive vaccinations. Here we studied the adherence of various population groups and healthcare workers to vaccination.

Materials and Methods. We conducted an original survey among 1147 university students, 214 parents and 512 physicians.

Results. Among the students of humanitarian and technical faculties, only 33% and 37% respectively showed a positive attitude to immunoprevention. This indicator, however, was higher in medical students and physicians (76% and 80%, respectively). Overall awareness of all population groups on immunization is insufficient to perform such measures efficiently. The reasons of low adherence include anti-vaccine propaganda, negative attitude and lack of awareness of healthcare workers on immunoprevention efficiency.

Conclusion. Further large efforts are urgently needed to increase the adherence to immunization both in general population and healthcare professionals. The primary task is to eliminate the lack of information on the role and importance of immunization in maintaining population health.
Influence of seed treatment with mineral nutrient products on emergence and growth in spring oilseed rape (Brassica napus L.)
Authors: Wallenhammar Ann-Charlotte E , Stoltz Eva
Published: December 2019

Seed treatment with mineral nutrients in spring oilseed rape (SOR) under cold climatic conditions has the potential to improve the outcome of production. The objectives of this study were to investigate the effects of mineral nutrients applied as seed treatment on germination and growth of roots and biomass in SOR. In addition, seed yield and oil content were also measured. Seed vigour tests and in-field experiments were performed in Central Sweden in 2016 and 2017. Seven products with different composition of mineral nutrients were applied to the seed in a combination with binder, filler and fungicide (BFF), or applied directly onto the seed. The results showed that a treatment with mineral nutrients increased the plant size at stage BBCH 60 (early flowering stage) when the products were applied in combination with BFF in the field experiments. However, the increased plant size did not influence seed yield. Furthermore, when seeds were treated only with a nutrient product the addition of BFF decreased plant size by 10% on average and seed and crude fat yields by 4% on average. The use of BFF may thereby be questioned and is subject to further investigation.

Legumes are particularly susceptible to clostridial fermentation when ensiled because of their high buffering capacity and water-soluble carbohydrate contents. The aim of the study was to investigate if a sodium nitrite treatment (900 g t-1 herbage in fresh matter [FM]) impairs butyric acid fermentation of red clover-timothy-meadow fescue silage compared with formic acid-treated (4 l t-1 FM) and untreated silage. The sward was harvested after wilting at low dry matter (DM) (LDM, 194 g kg-1) and high DM (HDM, 314 g kg-1) concentrations and half of the herbage batches were inoculated with Clostridium tyrobutyricum spores before additive treatments. No butyric acid fermentation was observed in HDM silages probably because of the relatively high DM and nitrate contents of the herbage mixture. In LDM silage butyric acid was detected only in formic acid-treated silage, and the number of clostridia copies was higher in formic acid-treated than in sodium nitrite treated silage. Sodium nitrite treatment was superior to FA treatment in suppressing clostridial fermentation in the LDM silages.
Valokuvan nainen
Authors: Schreck Hanna-Reetta
Published: December 2019

Artikkeli tutkii kuvataiteilija Ellen Thesleffin (1869-1954) valokuvia ja niiden suhdetta hänen elämäänsä, aikakauteensa ja maalarin työhönsä. Tarkemman tarkastelun kohteeksi on valikoitunut seitsemän omavalokuvaa Thesleffistä noin 1890-luvun alusta. Lisäksi artikkelissa rinnastetaan Thesleffin valokuvia hänen vuosina 1894-95 maalaamaansa Omakuvaan sekä siitä otettuun valokuvaan.

 

Kuvien Ellen Thesleff ilmentää koko ruumiillaan, valokuvallisella olemassaolollaan, jotakin erityistä. Kuvissa esiintyy kapinallinen nainen, joka katsoo suoraan kohti, myös kameraan ja hänellä on lyhyet hiukset. Tutkija Juliet McMasterin mukaan naisten kajoaminen omiin hiuksiinsa oli ”feminiininen itsenäisyydenjulistus”, koska saksia käyttävä henkilö oli nainen itse. Taiteilijan sukupuolipiirteitä liudentavan olemuksen voi lukea 1800-luvun asenneilmastossa itsevarmuutena, joka pohjautui oman kyvykkyyden tiedostamiseen ja sen korostamiseen. Queer-teoreetikko Judith Halberstamin (Female Masculinity 1998) mukaan maskuliinisuus ei palaudu vain miehen kehoon, vaan maskuliinisuutta tekevät myös naiset – se määrittyy toiminnan, asennoitumisen ja itseilmaisun kautta.

 

Thesleffin omavalokuvien avulla voimme tutkia, miten hän otti osaa modernin naissubjektin synnyttämiseen ja siihen liittyviin keskusteluihin, ja eli modernia ruumiillisuutta. Thesleffin omavalokuvia on mahdollista lähestyä vapauttavina ja demokratisoivina kuvina. Hänen omissa verkostoissaan nämä valokuvat saattoivat toimia emansipoivasti, tuoden niin Thesleffille kuin hänen lähipiirilleen uusia kuvia ja käsityksiä siitä, mitä ruumiillisuus, sukupuoli ja toimijuus oli ja voisi olla.

Fractional Vegetation Cover Change Detection In Megacities Using Landsat Time-Series Images: A Case Study Of Hanoi City (Vietnam) During 1986-2019
Authors: Nguyen Thanh Tien
Published: December 2019

The objective of the study is to assess changes of fractional vegetation cover (FVC) in Hanoi megacity in period of 33 years from 1986 to 2016 based on a two endmember spectral mixture analysis (SMA) model using multi-spectral and multi-temporal Landsat-5 TM and -8 OLI images. Landsat TM/OLI images were first radiometrically corrected. FVC was then estimated by means of a combination of Normalized Difference Vegetation Index (NDVI) and classification method. The estimated FVC results were validated using the field survey data. The assessment of FVC changes was finally carried out using spatial analysis in GIS. A case study from Hanoi city shows that: (i) the proposed approach performed well in estimating the FVC retrieved from the Landsat-8 OLI data and had good consistency with in situ measurements with the statistically achieved root mean square error (RMSE) of 0.02 (R 2 =0.935); (ii) total FVC area of 321.6 km 2 (accounting for 9.61% of the total area) was slightly reduced in the center of the city, whereas, FVC increased markedly with an area of 1163.6 km 2 (accounting for 34.78% of the total area) in suburban and rural areas. The results from this study demonstrate the combination of NDVI and classification method using Landsat images are promising for assessing FVC change in megacities.

Mercury is a widespread environmental pollutant becoming a crucial health concern as a result of natural and anthropogenic releases. Understanding Hg distribution pattern between different functional urban areas is needed for urban pollution control and health impact assessment. Therefore, in this paper urban soil Hg spatial distribution, pollution level evaluation, and mercury-induced health risks were studied, for different urban functional areas (355 samples) and kindergartens (18 samples) of Vanadzor. Geospatial mapping and the geostatistical analysis suggest that Hg concentration in the entire area of Vanadzor and its kindergartens has a natural origin, besides a certain anthropogenic impact on some urban sites. According to geoaccumulation index (Igeo), uncontaminated or moderately contaminated levels were detected only in 2 samples from industrial area and 5 samples from residential area, the remaining samples were classified as uncontaminated. In all kindergartens and the 22.15 sq.km of the city (270 samples) are characterized by low level potential ecological risk, whereas 3.85 sq.km (85 samples) correspond to moderate and for 1 sampling site high level of potential ecological risk. A non-carcinogenic health risk assessed for children and adults indicates health hazards neither in Vanadzor entire areas nor in kindergartens. The hazard index (HI) in each urban functional area is less than allowable level (HI <1) for children and adults. Obtained results are indicative and offer the ability for better management of urban soil and urban planning in terms of Hg pollution regulation in different functional areas.
