Background: Epigenetic regulation plays vital roles in the oncogenesis and treatment of diffuse large B-cell lymphoma (DLBCL). The H3K9me3-specific histone methyltransferase SUV39H1 is an epigenetic gene that promotes the progression of a variety of malignancies. However, the roles of SUV39H1 in DLBCL remain unclear.Methods: Initially, the Oncomine, Cancer Cell Line Encyclopedia (CCLE), UALCAN and Gene Expression Profiling Interactive Analysis (GEPIA) databases were searched to explore the expression of SUV39H1 in DLBCL. The clinical parameters and pathological sections of 61 successive patients, including 47 cases of DLBCL and 14 cases of reactive lymphoid hyperplasia, were collected from January 2019 to November 2020. Immunohistochemistry was conducted to verify the results of the database search. Finally, relevant parameters and pathological results were combined to analyze the expression of SUV39H1.Results: We found that the expression of SUV39H1 in DLBCL tissues was higher than that in normal and other cancer tissues (P<0.05) in database and immunohistochemistry analyses. Among the analyzed clinical parameters, only tumor size was closely associated with SUV39H1 (P=0.037), suggesting that patients with high SUV39H1 expression are less likely to develop tumors over 7.5 cm in size. Regarding survival, the group with high SUV39H1 expression had a lower survival rate than the group with low SUV39H1 expression in terms of 10-year disease-free survival (DFS) according to the database analyses (P=0.035). However, SUV39H1 was revealed as an independent predictor of overall survival (OS) and progression-free survival (PFS) in patients from both databases and our hospital (P>0.05).Conclusion: SUV39H1 expression is higher in DLBCL tissues than in normal and other cancer tissues, indicating that DLBCL patients may not develop bulky tumors over follow-up and suggesting that SUV39H1 might serve not only as a predictive factor in the clinic but also as a target for the epigenetic therapy of DLBCL.

Published: April 2021

Background

To date, little is known about the virulence characteristics of pyogenic liver abscess (PLA) that cause multidrug resistant (MDR) Klebsiella pneumoniae (K. pneumoniae), which might be due to the rarity of these strains. This study aimed to analyze the virulence characteristics and molecular epidemiology of 12 MDR strains obtained from 163 PLA cases in a tertiary teaching hospital from the perspective of clinical characteristics, virulence phenotypes, and genotypes.
Methods

The MDR strains were obtained from sterile fluid samples collected from patients with PLA. The antimicrobial susceptibility testing was confirmed by the agar dilution method and microdilution broth method. The virulence phenotypes were analyzed by the growth curves, string test, capsular quantification, serum killing test, biofilm formation assay and infection model. Polymerase chain reaction (PCR) was used to investigate the virulence genotypes. The molecular epidemiology was identified by multilocus sequence typing (MLST).
Results

The results of growth curves, string test, capsular quantification, serum killing test, biofilm formation assay, and infection model revealed that the virulence phenotypes of the 12 PLA-causing MDR K. pneumoniae were similar to or more obvious than those of the typical hypervirulent K. pneumoniae strains. These MDR strains were mainly non-K1/K2 serotypes and carried multiple virulence genes. The results of MLST illustrated that the MDR strains were categorized into 9 sequence types.
Conclusions

This is the first study to analyze the virulence characteristics in PLA-causing MDR strains. The data revealed the coexistence of hypervirulence and MDR in PLA-causing MDR K. pneumoniae strains, and the clones of these strains were diverse and scattered. Also, one ST11 carbapenem-resistant hypervirulent strain was identified in PLA.
High detection rate and risk factors of melanosis coli in end-stage renal disease patients awaiting kidney transplantation: a single-center retrospective study in China

Published: April 2021

BackgroundRhubarb-containing Traditional Chinese Medicine (TCM) is widely used to manage renal failure in China. Studies show that anthranoids contained in rhubarb are related to the occurrence of melanosis coli (MC). However, no study on the rate of MC in end-stage renal disease (ESRD) patients has been reported.MethodsWe conducted a retrospective study on 99 ESRD patients who received a colonoscopy as part of pre-transplant work-up between Jan 1, 2017 and July 1, 2020 in a single center in Beijing, China. 200 age- and gender-matched subjects with normal renal function and received a colonoscopy for health screening in the same period were randomly selected as control group. Univariate analysis and multivariate logistic regression were performed in succession to determine the association between ESRD and MC, and also probe the independent MC risk factors in ESRD patients.ResultsAmong the 99 ESRD patients, MC was detected in 19, with a detection rate of 19.2% (95% confidence interval [CI]: 11.3%, 27.1%). In contrast, among 200 control subjects, MC was only detected in 1 subject, with an detection rate of 0.5% (95%CI: 0.5%, 1.5%) (ESRD vs. control: odds ratio [OR] = 47.263, 95% CI: 6.222, 358.981; p=0.000). After adjustment of age, body mass index(BMI), albumin, hemoglobin and Charlson comorbidity index, being ESRD was still associated with the presence of MC (OR = 36.251, 95%CI: 3.435, 382.559, p = 0.003). In ESRD patients, both univariate analysis (OR = 4.358, 95% CI: 1.329, 14.286; p = 0.012) and multivariate logistic regression (OR = 4.916, 95% CI: 1.462, 16.525, p = 0.010) found that past use of Rhubarb-containing TCM was the only independent risk factor of MC. However, when the ESRD patients with above use history were excluded, MC rate in ESRD was still higher than non-ESRD group (8.5% vs. 0.5%; OR = 18.512, 95% CI: 2.019, 169.755; p = 0.000).ConclusionOur work highlights that MC rate is high and rhubarb-containing TCM use might be a risk factor in Chinese ESRD patients. There is a need for arranging high quality studies to examine the development of MC in ESRD, especially those awaiting transplantation.

Urban green infrastructure provides ecosystem
services that are essential to human wellbeing. A dearth of national-scale
assessments in the Global South has precluded the ability to explore how
political regimes, such as the forced racial segregation in South Africa during
and after Apartheid, have influenced the extent of and access to green infrastructure
over time. We investigate whether there are disparities in green infrastructure
distributions across race and income geographies in urban South Africa. Using
open-source satellite imagery and geographic information, along with national
census statistics, we find that public and private green infrastructure is more
abundant, accessible, greener and more treed in high-income relative to
low-income areas, and in areas where previously advantaged racial groups (i.e.
White citizens) reside.

The production of plant fibre products is
considered a promising pathway for contributing to people’s livelihoods
particularly in developing countries, where economic options might be limited.
However, there are limited comparative studies across countries on plant fibre
products, making it difficult to examine how local and broader biophysical,
socioeconomic, cultural and policy contexts influence craft production patterns
in terms of primary plant resources used, products made and contributions to
livelihoods. Using household surveys for data collection, this paper presents
findings from a comparative analysis of plant fibre craft production and income
in three southern African countries, Eswatini, Malawi and Zimbabwe

In this study, phenolic extracts of strawberry, red raspberry, sour cherry, and cornelian cherry were obtained using methanol, ethanol, 80% methanol, and 80% ethanol as extraction solvents. Total phenolic content and antioxidant activities (ferric reducing power, antioxidant activity in linoleic acid emulsion, and DPPH radical scavenging activity) were determined for each fruit extracts at different concentrations (0.5, 1, 2 and 3 mg mL-1). Antioxidant activities of all extracts were increased with increased concentration (P<0.05). There was a correlation between total phenol content and antioxidant activity of the extracts. According to total phenolic content and antioxidant activity analyses, strawberry extracts had significantly higher antioxidant activity compared to other fruit extracts (P<0.05). Reducing power of raspberry ethanol extract was the lowest and sour cherry had higher reducing power than cornelian cherry for the same solvent. Aqueous ethanol extracts had higher antioxidant activity in linoleic acid emulsion among fruit extracts at all concentrations. Except for strawberry extracts, 80% methanol extract of red raspberry had the highest DPPH radical scavenging activity at all the concentration tested, followed by cornelian cherry and sour cherry extracts.

Bu çalışmada, bazı Arbusküler Mikorhizal Fungus (AMF) türleri (Rhizophagus intraradices (Ri) ve Funneliformis mosseae (Fm)) ile bazı uçucu yağların (kekik, nane ve adaçayı), domatesteki önemli hastalıklar arasında yer alan Fusarium oxysporum f. sp. radicis- lycopersici (Jarvis & Shoemaker) (FORL)‘nin yol açtığı kök ve kök boğazı çürüklüğü hastalığı üzerine etkileri incelenmiştir. Çalışmanın birinci aşamasında, in-vitro koşularda üç farklı uçucu yağ ile bunların beş farklı dozu (25, 50, 75, 100 ve 150 μl L-1), FORL’ye karşı denenmiştir. Çalışma sonucunda patojenin miseliyal koloni gelişiminin sadece kekikten elde edilen uçucu yağın (KUY) tüm dozlarının %50.8-80.8 oranında engellediği; en iyi dozun ise 150 μl L-1 doz olduğu saptanmıştır. Çalışmanın ikinci aşamasında in-vivo koşullarında yetiştirilen domates bitkilerine, AMF türleri ile 150 μl L-1 dozundaki KUY uygulanmıştır. Uygulama gruplarının bitki gelişimine önemli bir etkileri olmamakla beraber, AMF kolonizasyon yoğunluklarına ve mikorizal bağımlılık kriterlerine göre en iyi uyumun Ri ile olduğu saptanmıştır. Çalışmanın üçüncü aşamasında Ri ile KUY’un 150 μl L-1 doz uygulamasının, domates bitkisinde FORL’ye olan etkileri araştırılmıştır. Tüm uygulamalar kontrol grubuna göre hastalığı %28-55 oranlarında baskılarken, Ri+KUY+FORL kombinasyonun patojene karşı en etkili grup olduğu, uygulama gruplarının bitkinin morfolojik gelişimine önemli katkı sağlamadığı gözlenmiştir. AMF kök kolonizasyon yoğunluğu açısından en yüksek değerler Ri ve Ri+KUY+FORL uygulama gruplarında sırasıyla, %43.89 ile %37.77 oranlarında olurken, AMF spor yoğunluklarında istatistiki olarak önemli fark oluşmamıştır. Mikorizal bağımlılık ise sadece Ri+KUY uygulamasında tespit edilmiştir. Sonuç olarak, bu çalışmada kullanılan Ri ile KUY uygulamalarının patojeni engellemede önemli bir potansiyele sahip olduğu, ancak bitki gelişimine önemli katkı sağlamadığı belirlenmiştir.
The Evaluations and Comparisons of Nuclear and Chloroplast DNA Regions Based on Species Identification and Phylogenetic Relationships of Crocus L. Taxa
Authors: YILMAZ Aykut
Published: April 2021

The genus Crocus L. (Iridaceae) consists of about 200 species distributed from western Europe and north west Africa to western China. The genus is taxonomically very problematic and day after day it becomes more difficult to understand the relationships between Crocus species because of the identification of new species. Recently, the studies based on DNA sequences are frequently used for the solution of taxonomic problems, the determination of species diversity and especially the evaluation of phylogenetic relationships among the studied taxa. The use of the regions belonging to nuclear DNA and especially chloroplast genome and the combinations of these regions are frequently recommended in many studies. However, there is no information about suitable barcoding regions that can be used for all plant groups. This study focuses on determination of the most succesful barcoding regions, understanding the species discrimination abilities and finally evaluation of phylogenetic relationships among the Crocus taxa using one region from nuclear DNA (ITS1-5.8S rRNA gene-ITS2) and four regions from chloroplast DNA (1. trnK-matK IGS, 2. partial psbA gene-psbA/trnH IGS-partial trnH gene, 3. rpoC1 gene, 4. partial trnL gene-trnL/trnF IGS-partial trnF gene). Sequence informations for related DNA regions were obtained from NCBI. As a result, it can be stated that the region which is only covering ITS1-5.8S rRNA gene-ITS2 separated the all taxa in species level and it is more beneficial for the phylogenetically evaluation of Crocus taxa. Furthermore, dendrogram show taxonomic problems belonging to some species in the genus such as C. biflorus taxa.

Published: April 2021

A sustainable solid waste management system planning is a complex and interdisciplinary subject, which requires considering technical, environmental, economic, and social factors. Landfills play an essential role in solid waste management strategies, and landfilling is an extensively accepted preference for the clearance of solid waste worldwide. Site selection of landfill facilities can be a considerable problem as all infrastructural projects can deteriorate the ecology of the site on which they are developed because of changing land uses, loss of habitats, and displacement of fauna. These effects are mainly specific for location and need to be evaluated on every example. Landfill site selection is related to certain factors and limitations defined by natural and artificial thresholds and/or legislation. Legal provisions may vary according to the country's policy and even to the provincial policies. In addition to these features of study zones or sites, landfill site selection methods may have different criteria and sub-criteria in identifying parameters. This paper aims to identify landfill site(s) multicriteria decision analysis depending on Edirne's environmentally sensitive areas by using the Geographic Information System (GIS) technique. Data of land use, geologic features, protected areas, natural and archeological sites, transportation network, hydrological data, soil suitability for agricultural activities, and land capability classes which have been acquired from the relevant public authorities were used to proposed model. Regional factors were identified and assessed according to the risk of contamination for environmental components such as natural resources, sensitive ecosystems, and unique habitats. The chosen criteria were graded in this context, and alternative landfill sites were proposed by applying GIS-based analysis. According to the analysis, the northern subprovince of the study area, Lalapasa, has the most appropriate landfill sites.

Published: April 2021

One of the main problems in the control of the coupled tank liquid level systems, which are used frequently in water treatment systems and petrochemical industry today, is to determine the water flow rate between the two tanks. In this paper, proportional-integral +feed forward control method (PI+FF), whose parameters are determined using genetic algorithm (GA), one of the heuristic optimization methods, is used to solve this problem. In addition, in order to show the performance of the GA-based controller, the PI+FF controller that PI parameters obtained using the Ziegler-Nichols (Z-N) method are applied to the same system and the real-time application results of both controllers are compared. The experimental results showed that the controller, which parameters are determined by GA, reached the desired reference value with less settling time and less overshooting when it compared to the Z-N method based controller, and also it has given faster response to sudden changes in the system.

Edible wild plants are important food sources of the increasing world population and contribute to the healthy functioning of the body. Some of the edible wild plants, which are considered among the favourite flavours and consumed with pleasure in many countries, are rich in trace elements that play an effective role in the fight against various diseases. Ferula, a genus of edible wild plants in the Apiaceae family, is also known worldwide for its aromatic composition and medicinal properties. In this study, the essential oil of F. orientalis obtained by hydrodistillation and water, ethanol: water, methanol: water, chloroform, and n-hexane extracts prepared by classical and ultrasonic were studied. According to the mineral composition data determined by the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), the essential oil was found to contain only sodium, potassium, manganese, and aluminum, among the 18 elements scanned. The most common elements found in the extracts were potassium, sodium, and phosphorus, and their amounts varied between 982.504- 42 282.486 ppm, 3267.141- 39 103.835 ppm, and 1898.652- 9280.814 ppm, respectively. According to the results, the ultrasound process significantly increased the mineral transfer to the extracts (p< 0.01).

Bu çalışmada; keskin kokusu ve tadı nedeniyle tüketimi sınırlı olan ve sağlığa faydası tespit edilen çam propolis ekstraktının mikroenkapsüle edilerek top kek üretiminde kullanılabilirliğinin araştırılması amaçlanmıştır. Sadece çam ağaçlarının bulunduğu Muğla bölgesinden temin edilen propolisin ultrasonik ekstraksiyonu sonucunda elde edilen ekstrakt, maltodekstrin/arap zamkı kombinasyonu ile mikroenkapsüle edilmiştir. Mikroenkapsüle çam propolisi (MÇP) 4 farklı oranda (%0 [kontrol], %6, %9, %15) un ile yer değiştirme prensibine göre kek formülasyonuna ilave edilmiştir. MÇP ilave edilerek üretilen top keklerin toplam fenolik madde ve antioksidan aktivite değerlerinin yanı sıra bazı kimyasal, tekstürel, fiziksel ve duyusal özellikleri incelenmiştir. MÇP ilave edilme oranının artmasıyla kek örneklerinin toplam fenolik madde, antioksidan aktivite değeri, nem, protein, yağ ve kül içerikleri artmış, kabuk ve iç L* değeri azalmış, a* ve b* değerinde artış meydana gelmiştir. MÇP ilavesi keklerin tekstürel özelliklerine önemli düzeyde (P<0.05) etki etmiş ve ilave edilme oranının artmasıyla sertlik değerinde azalma meydana gelmiştir. Duyusal özelliklerde ise MÇP’nin %6 oranında kullanılması top keklerde olumsuz bir etki yaratmamış ancak daha yüksek oranlarda kullanılması beğeni değerini olumsuz etkilemiştir. Çalışma sonucunda farklı yaş grupları ve gelir düzeyine sahip kişiler tarafından sevilerek tüketilen top keklerin fonksiyonel bir ürün haline getirilebilmesi için %6 seviyesine kadar MÇP’nin duyusal özelliklerde bir olumsuzluğa yol açmadan top kek üretiminde kullanılabileceği tespit edilmiştir.

Authors: KUMLAY Ahmet Metin , KAYA Canan , YILDIRIM Bünyamin
Published: April 2021

The study compared the effects of MS medium containing 0.1 mg L-1 gibberellic acid (GA3) and α-naphthaleneacetic acid (NAA) in combination with 2.0 mg L-1 of kinetin (KIN), 2.0 mg L-1 of benzyl aminopurine (BAP), 1.0 mg L-1 of zeatine riboside (ZR), and 0.5 mg L-1 of jasmonic acid (JA) for the micropropagation development of three potato (Solanum tuberosum L.) cultivars namely Caspar, Granola and Pasinler-92 using binodal stem explants. The results of this research clearly indicated that inclusion of JA among the other plant growth regulators significantly increased shoot regeneration and other characteristics of all potato cultivars used in the study. The minimum days to shoot proliferation on three cultivars ranged 4.0–5.5 d (best result on cv. Pasinler-92) on MS medium containing 0.5 mg L-1 JA. The minimum time to root initiation (11.0 d) was observed on cv. Pasinler-92 on the same medium. The maximum number of axillary shoots (15.25) and nodes (19.0), maximum shoot length (17.25 cm), leaves (19.0) and roots (25.25) were noted on cv. Caspar. The longest roots (18.45 cm) on cv. Pasinler-92, and the maximum fresh weight (404.87 mg) and dry weight (61.85 mg) of plantlets from cv. Granola were also recorded on MS medium fortified with 0.1 mg L-1 GA3+0.1 mg L-1 NAA+0.5 mg L-1 JA.
Maxilon Blue 5G Removal by Bimetallic Pt/Co Loaded on GO Material under Ultrasonic Conditions from Aquatic Medium
Authors: ÇALIMLI Mehmet Harbi
Published: April 2021

Bimetallic Pt/Co loaded on GO adsorbance was produced following a series of simple hydrothermal methods. The produced bimetallic Pt/Co loaded GO material was used in the maxilon blue 5G removal (MB 5G) and investigated its adsorption studies. The adsorption studies on removal of MB 5G using the bimetallic Pt/Co loaded on GO material were carried out performing different experimental conditions like ultrasonic irradiation time (1-120 min), temperature (24-55 oC), initial MB 5G concentration (0.7.10-5- 1.5.10-5 M), and pH (4- 10) to detect optimum removal conditions. The reaction kinetics were investigated by pairing the so-called first-order pseudo-second-order and intraparticle diffusion in the adsorption process study. In addition, enthalpy, entropy and Gibbs free energy, and thermodynamic activation functions were investigated in order to understand the adsorption mechanism. These data showed that the bimetallic Pt/Co loaded on GO material can be used as an effective nano adsorbent for the removal of MB 5G as an organic pollutant in an aquatic medium.
Social responsibility as the dominant driver of the evolution of reporting from financial to non-financial: theory and methodology
Authors: Bychkova Svetlana , Karelskaia Svetlana , Abdalova Elena , Zhidkova Elena
Published: April 2021

Introduction. For over half a century, corporate social responsibility has been in the center of scientific discourse. Its basic concept has become part of strategic management, changing the content of financial reporting and leading to new forms of corporate reporting.

Study objects and methods. The article substantiated the importance of studying corporate social responsibility (CSR) concepts and national models. The study covered the CSR basic concept, targets and paradigms. The evolution of CSR was considered in terms of its impact on the formation of non-financial reporting.

Results and discussion. The authors identified two stages of non-financial reporting development and two directions for the convergence of financial and non-financial reporting. They proposed an assessment matrix to measure facts, actions, and resources in the past, present, and future. This matrix can help companies to generate information for integrated reporting by showing the impact of each type of capital (financial, production, human, intellectual, social, and environmental) on their value creation. Within a promising direction for developing non-financial reporting in conjunction with financial reporting, the authors set requirements to reflect the impact of climate risks on the company’s activities in accordance with the recommendations of the Task Force on Climate-Related Financial Disclosures. The authors discussed both standardized and their own approaches to CSR indicators. Finally, they addressed the problem of reliability of non-financial reporting, discussed various forms of its verification (taking evidence from food industry enterprises), and set specific principles to control non-financial reporting indicators.

Conclusion. The authors identified further promising areas of research in the theory and practice of CSR. Their findings can be used in scientific debates on CSR and in the practice of corporate reporting.
Egyptian kishk as a fortificant: Impact on the quality of biscuit
Authors: Ibrahim Gamil , Bahgaat Wafaa , Hussein Ahmed
Published: April 2021

Introduction. Biscuit is a mass-consumption product worldwide. As biscuit contains low amount of protein, it can be fortified with protein-containing raw materials. In the present work, we fortified biscuit with kishk, an Egyptian dairy product, and evaluated changes in its physicochemical properties and volatile compounds.

Study objects and methods. We analyzed biscuit from wheat flour (control sample) and biscuit form wheat flour with 10, 20, 30, 40, and 50% of kishk (experimental samples). The experiments were carried out by using standard methods.

Results and discussion. The fortified biscuit samples showed higher lightness (L*) values than control. The antioxidant activity in the biscuit increased with the increasing amount of kishk. Aldehydes were the main volatile compounds in all the biscuit samples, followed by sulfur-containing compounds and alcohols. The predominant aldehyde was benzldehyde. However, kishk in amounts more than 20% affected adversely the aroma, taste and texture, as well as volatile compounds of the biscuits. Both the control and fortified with kishk biscuits contained an increased amount of total phenolic compounds. Based on sensory evaluation and volatile analysis, the most acceptable amount of kishk for fortification of biscuit was 10%.

Conclusion. Fortification of biscuit with Egyptian kishk enhanced its protein, fat and fiber, as well as antioxidant activity at all levels of fortification with no significant effect on appearance and color. Further studies are needed to evaluate storage conditions and shelf life of biscuits with kishk.
Minced products from undersized sea fish: new industrial technology
Authors: Gorbatovskiy Andrey , Rakityanskaya Irina , Kaledina Marina
Published: April 2021

Introduction. The ever-growing world population and protein deficiency increase the demand for products of animal origin, especially fish-based. However, canned foods and fillets, which are the most popular types of fish products, are made from medium-sized and large fish. In spite of the fact that undersized fish is cheap, it requires manual processing and remains so time and labour consuming that it is utilized for non-food purposes. The research objective was to develop a new technology for processing undersized sea fish into minced ready-to-eat products.

Study objects and methods. The study featured experimental samples of fish mince with texturing agents and food additives vs. control samples of pure fish mince. The experiment involved block-frozen Peruvian anchovy (Engraulis ringens L.). The anchovy was minced without pre-defrosting, gutting, or beheading. The experimental and control samples underwent sensory evaluation and were tested for moisture content, water-binding capacity, and rheological properties using a PNDP-penetrometer.

Results and discussion. Adding 3.6% of wheat fiber, ≤ 15% of pea flour, ≤ 10% of textured soy, and 12% of onion improved the sensory and technological profiles of the finished product. The recommended mass fraction of fish in the finished product did not exceed 55%, as a higher amount deteriorated the sensory quality of the product. The textured soy provided the optimal texture. The fish balls were cooked from the fish mince, which were deep-fried in breadcrumbs, received a high score for sensory properties and could be recommended as basis for various formulations.

Conclusion. Minced undersized fish, traditionally used as fertilizers or crude product, proved to be an advantageous semi-finished and ready-to-eat product. The developed technology is relevant for most undersized block-frozen sea fish.

Authors: Chhabra Shakuntala , Suman Akanksha
Published: April 2021

OBJECTIVE: Knowing about complications, care sought by women is essential for understanding the risks, services, programs, and policies for abortion care. This study aimed to know the magnitude of abortion complications and to define the care sought by rural tribal women.
STUDY DESIGN: Rural community-based cross-sectional study was carried out in villages near Sewagram Wardha and Melghat, Amravati, Maharashtra, India.
RESULTS: Spontaneous abortions rate was 3.30% in villages around Sewagram and 0.32% in villages of Melghat. The reported complications rate for induced abortions was 1% in Sewagram villages and 0.1%in Melghat villages. In Sewagram villages, among 24 (4.3%) women who had complications with spontaneous abortions, the reported complications were: vaginal bleeding in 33.3% (1.4% of all spontaneous abortions), abdominal pain in 33.3%, weakness in 29.16% (1.2% all spontaneous abortions), backache in16.6% (0.7%of spontaneous abortions), fever in 12.5%(0.5% of spontaneous abortions), excessive vaginal discharge in 8.33% (0.3% of spontaneous abortions), and other complications in 8.33% (0.36% of spontaneous abortions) women. Among 7 women (3.9% of all 177), who reported complications after induced abortions, 57.1% (2.2% of all induced abortions) reported, vaginal bleeding and 28.5% (1.1% of induced abortions) reported abdominal pain. In Melghat villages only 4 women reported complications with spontaneous abortions (0.32% spontaneous abortions): two (0.16% spontaneous abortions) reported abdominal pain, one (0.08% spontaneous abortions) reported vaginal bleeding, and one (0.08% of spontaneous abortions) reported backache. In villages of Melghat 2 women (3.7%) out of 27 induced abortions cases had complications: one had vaginal bleeding, discharge, pain, weakness, another only vaginal bleeding. In villages of Melghat 2 of the total 6 sought health facility care, however, no one reported to specialists despite complications. Nevertheless, there was neither abortion-related mortality nor near-miss morbidity or severe morbidity during the same duration.
CONCLUSION: Research is needed about traditional therapies, reverse pharmacology, socio-behavioral issues in addition to creating awareness in women about abortion complications, long-term squeal, and the necessity of care-seeking.

Authors: Yurtcu Engin , Mutlu Sibel , Ozkaya Enis
Published: April 2021

OBJECTIVE: To investigate the effects of pre-pregnancy body mass index and weight gain during pregnancy on perinatal outcomes and delivery mode.
STUDY DESIGN: In this retrospective cohort study, 722 pregnant women giving birth between 2018-2019 were screened from our hospital database. First, they were divided into four groups according to their pre-pregnancy body mass index (low-weight/normal-weight/overweight/obese), and then they were redivided into three groups according to pregnancy weight gain (≤7/8-15/≥16 kg). Prenatal body mass index and pregnancy weight gain were compared concerning maternal-neonatal results and mode of delivery.
RESULTS: According to pre-pregnancy body mass index, among the obese pregnant group, gestational diabetes mellitus (p<0.001), preeclampsia (p=0.029), preterm delivery (p=0.011) and cesarean delivery (p=0.061) rates were more common. As the body mass index increases, neonatal intensive care requirement (p=0.0020) and low 1st minute APGAR scores (p=0.019) were detected more frequently. However, as pregnancy weight gain decreased, preterm delivery (p=0.041) increased. Also, birth weight increased (p<0.001) with the weight gain of the pregnant. Pregnant women gaining more than 16 kg were associated either with a lower <2500 g or a higher birth weight risk >4000 g.
CONCLUSION: Pre-pregnancy high body mass index is associated with negative obstetric outcomes like gestational diabetes, preeclampsia, preterm delivery, and increased cesarean rates, and poor fetal incidences with a low APGAR score and high neonatal intensive care admission rates.
Использование методики «Сетевой самоотчет» для изучения специфики интернет-социализации подростков и юношей с нарушением интеллекта
Authors: Кузьмина Татьяна И.
Published: April 2021

Введение. Изучение специфики сетевой социализации подростков и юношей с ОВЗ и, в частности, с нарушением интеллекта является новым и перспективным направлением в специальной психологии и нуждается в разработке методологических подходов и методических основ проведения исследований подобного рода.

Методы. Изучение специфики сетевой социализации лиц с нарушением интеллекта связано с описанием особенностей их социализационно-сетевого становления, в сравнении с нормативно развивающимися сверстниками предполагающим понимание исследователем интернет-взаимодействия как формы альтернативной коммуникации, способа адаптации и потенциального источника сетевых рисков личности. Методический инструментарий представлен авторской методикой «Сетевой самоотчет», апробированной с участием 181 респондента подросткового и юношеского возраста с нормативным развитием и 119 респондентов тех же возрастов с нарушением интеллекта.

Результаты. Апробация методики «Сетевой самоотчет» с участием выборок подростков и юношей с умственной отсталостью и их нормативно развивающихся сверстников показала, что данный инструментарий доступен для выполнения респондентам обеих групп и применим для выявления качественно-количественных различий между выборками. У респондентов с умственной отсталостью наблюдаются меньшая активность в Сети по поиску информации, низкая осведомленность о сетевых явлениях и феноменах сетевого взаимодействия, использование Интернета как дополнительного поля реализации выраженной потребности в общении и более агрессивная защита своего сетевого пространства от вмешательства родителей.

Обсуждение результатов. Представленные данные открывают ряд перспективных направлений исследования в предметной области сетевой социализации обучающихся с нарушением развития: 1) первичный скрининг в рамках ведущего нарушения по сравнению с нормативно развивающимися сверстниками; 2) углубленное исследование по возрастным диапазонам в рамках одной нозологии и выявление возрастных различий внутри одной нозологической группы; 3) дифференцированное исследование по сравнению разных нозологических категорий и выявлению межгрупповых различий.
