Objective. To study the immediate and late follow-up results of treatment in patients, suffering hemorrhoids, to whom transanal hemorrhoidal desarterization under ultrasound rectodopplerometry control was done, and to compare them with results of treatment in patients, operated in accordance to procedure of standard hemorrhoidectomy.
Materials and methods. There were analyzed the results of treatment of 111 patients, suffering hemorrhoids. The main group have consisted of 50 patients, to whom transanal hemorrhoidal desarterization under ultrasound rectodopplerometry control was performed. Into control group 61 patients were included, who were operated in accordance to Parks procedure.
Results. In the main group the average time of the operation have constituted (50.1 ± 1.4) min, the patient stationary stay - (9.9 ± 0.7) days, the pain syndrome intensity in postoperative period was estimated as 2 - 3 points, what have appeared significantly lesser, than in the control group of the patients (p < 0.01). Good late follow-up results were achieved in 100% patients of the main group and in 88% of the control group.
Conclusion. There was established, that transanal hemorrhoidal desarterization under ultrasound rectodopplerometry control permits to reduce essentially the average time of the operation, the patients’ stationary stay, to lower the pain syndrome intensity, and to improve late follow-up results of the hemorrhoids treatment.

Authors: Yakovlev P. G. 
Published: April 2021

Objective. To determine the operative volume of surgical treatment in total radical resection of the bladder in autonomous regime and to estimate the survival indices in patients with low-differentiated cancer of the bladder depending on time of conduction of radical total resection of the bladder.
Materials and methods. Retrospectively 522 histories of the diseases were analyzed in the patients with diagnosis of low-differentiated cancer of the bladder, including 190, in whom radical total resection of the bladder was performed in 1998 - 2016 yrs period. The survival indices were determined. Using Kaplan-Meier method, comparative analysis of the survival indices in patients was done, to whom radical total resection or salvage resection of the bladder performed.
Results. Total radical resection of the bladder in autonomous regime was done in 24.7% patients with low-differentiated cancer of the bladder or in 67.9% patients, to whom total resection of the bladder was performed. The indices of total 3-, 5- and 10-yr survival of the patients have constituted 96, 93 and 45%, accordingly. The survival indices in the patients after organ-preserving treatment and further salvage total resection of the bladder for locally progression of cancer were better, than in the patients, to whom the treatment consisted of primary radical total resection of the bladder, but the difference have appeared statistically nonsignificant (p=0.286). Average period between conduction of organ-preserving treatment and salvage total resection of the bladder have constituted 34 mo.
Conclusion. Radical total resection of the bladder in autonomous regime constitutes the extended method of treatment of muscularly-invaded low-differentiated cancer of the bladder (performed in 24.7% of all the patients) and guarantees satisfactory late follow-up results while primary or postponed performance.

Published: April 2021

Skin is a part of a human body that covers the entire body and protect the lower layer from direct sunlight and another microorganism. Because of that, skin cells are always changing and could be changed because of genetic mutation that causes skin cancer. In general, skin cancer is divided into three groups, namely : skin cancer Basal cell carcinoma, skin cancer Squamous cell carcinoma, and skin cancer Melanoma. Melanoma skin cancer is caused by abnormal growth in melanocyte cells. Several methods are proposed to predict Melanoma skin cancer using ResNet, LeNet, and Support Vector Machine. System performance is measured based on the value of accuracy, precision, recall, and f-measure. This experiment is conducted using a Melanoma skin cancer dataset that obtained the average value in terms of accuracy, precision, recall, and f-measure are 0.94, 0.95, 0.92, and 0.94 respectively. Based on that result, the proposed DenseNet121 performs better with 0.94 accuracy, compared with ResNet, LeNet, and Support Vector Machine method.

Abstract — The role of parents is very important in the education of their children, even though parents have entrusted their children to school. Parents also have responsibility for continuing children's learning at home. Parents of course need information about their child's learning at school, so that they guide learning at home in accordance with the lessons learned at school. In order for the information to be conveyed properly, SDN 04 Bengkalis uses a Buku Penghubung. Buku penghubung is used as a medium for communication between teachers and parents. However, the problem that arises from using it is the lack of interest of parents in using buku penghubung. Buku penghubung, also often left behind, easy to lose, and prone to damage because made of paper. This research aims to build an android-based buku penghubung application. The application features announcements, daily grades, list of lessons, and attendance. The method in this research is the prototyping. The result of this research is an android-based buku penghubung application that can be used by teachers and parents. Application testing uses the black box testing and compatibility testing.

The development of technology is very helpful in agriculture by using the internet to get the information we need. The problem that farmers think of is that they cannot easily and quickly get information in the form of light intensity, precipitation, soil pH, soil moisture, soil temperature, humidity and air temperature. When farmers get the information they need from agricultural land, they usually get information through the internet so they are considered less efficient as it is quite time consuming. To solve this problem, a system is designed using the research and development method (RnD). A new Android-based application that can display data in text and graphics that are more easily accessible to farmers. This study creates an Android-based mobile application based on tests using the Android interface to display information about agricultural land conditions and display graphical data that is updated every 5 minutes.

Pathologic response after neoadjuvant chemotherapy predicts locoregional control in patients with triple negative breast cancer
Authors: Einck John P. , Chen Victor E. , Zakeri Kaveh 
Published: April 2021

Abstract

Purpose
Our goal was to determine the impact of pathologic response after neoadjuvant chemotherapy in triple negative breast cancer (TNBC) on the subsequent risk of locoregional recurrence (LRR) and disease-free survival (DFS) in the setting of adjuvant radiation therapy.

Methods and materials
This was an institutional review board–approved retrospective chart review of patients with clinical stage I-III breast cancer treated with neoadjuvant chemotherapy, local surgery (breast conservation or mastectomy), and adjuvant radiation therapy between 1997 and 2015. Medical records were reviewed for clinical stage, tumor grade and subtype, neoadjuvant chemotherapy regimen, type of surgery, pathologic stage, use of radiation therapy, date and location of recurrence, and date of death. Molecular subtypes were defined using immunohistochemistry and histologic grade. ypT0 and ypN0 were defined as no residual invasive disease in breast or nodes, respectively. LRR was defined as any failure within the breast, chest wall, or regional lymph nodes. Statistical analysis was performed; LRR and DFS rates over 30 months were determined from Kaplan-Meier plots.

Results
Ninety-four patients with TNBC were analyzed, of whom 72 received radiation therapy. This subgroup was isolated for further investigation. Median follow-up was 32.5 months in this group. The pathologic complete response (pCR) rate was 36%, and presence or absence of disease in breast and/or nodes was significantly predictive of LRR. In TNBC patients who received radiation therapy, 30-month LRR was 22% in 41 patients with ypT+ versus 0% in 31 patients with ypT0 (P = .003), 23% in 31 patients with ypN+ versus 5% in 41 patients with ypN0 (P = .016), and 20% in 46 patients with residual disease in breast or nodes versus 0% in 26 patients with pCR (P = .015). The difference in the rate of LRR between those who underwent lumpectomy versus mastectomy did not reach significance (8% vs 17%, respectively). Furthermore, patients with residual disease had a higher rate of DFS events (hazard ratio, 3.58; 95% confidence interval, 1.37-9.41; P = .006). The difference in DFS was not significantly associated with the type of surgery received.

Conclusions
Patients with TNBC treated with neoadjuvant chemotherapy who have residual disease in the breast or lymph nodes at the time of surgery have significantly higher rates of locoregional failure and lower DFS compared with those with a pCR despite the use of adjuvant radiation therapy. Strategies to intensify therapy for patients with residual disease warrant further investigation.
Congenital Heart Disease and Maternal Diabetes Mellitus
Authors: Petropoulos Andreas , Khudiyeva A , İsmailova İ 
Published: April 2021

Diabetes mellitus is a relatively common illness that can complicate pregnancy and result in an increased incidence of congenital malformations. Offspring of diabetic mothers suffering from type IDDM have a fivefold incidence of congenital malformations compared to pregnancies in the general healthy population. Specifically, the pattern of congenital heart disease (CHD) encountered among this group, with an emphasis on abnormalities of laterality, looping and conotruncal septation, suggesting that the maternal metabolic state affects cardiogenesis at a very early stage of the developmental period, prior to 7 weeks of gestation. Although many have been written on the effect of diabetes in pregnant women, less is known for the effects of type II DM and gestational diabetes mellitus (GDM) and its role in provoking CHD.
Aim of this paper is to review the literature regarding the types of CHD seen in offspring of mothers suffering from different types of diabetes mellitus, maternal types 1 and 2 and gestational and to comment on the incidences and any differences found in the types of detected CHD.
Right use of Screening Pulse Oximetry test for early detection of Critical Congenital Heart Diseases
Authors: Petropoulos Andreas , Huseynov Rustam 
Published: April 2021

Introduction: Preventive medicine is the ideal way in dealing with frequent and fatal diseases. Congenital heart disease (CHD) is responsible for the largest proportion of mortality caused by birth defects in the first year of life. Actual numbers and mortality from CHD is increasing. In the developed world the treatment of CHD has escalating costs for health care systems and private covered patients, while in low-income countries the resources are minimal. Prevention/early detection is urgently needed to tackle the increasing needs.
Aim: To justify why pulse oximetry (pox) is the best available, early detecting postnatal screening test currently.
Conclusion: Although CHD’s are both frequent and carry a high morbidity and mortality, we still lack a single, easy to apply, non-invasive and low-cost screening test, worldwide. The most advantageous method for minimizing CHD deaths worldwide seems to be currently, the combination of clinical assessment with pox.

Determination of Reinforced Concrete Rectangular Sections Having Plastic Moments Equal to all IPE Profiles
Authors: Beroual Sayeh , Samai Mohamed Laid 
Published: April 2021

The comparison between steel structures and reinforced concrete structures has always been governed by economy and response to earthquake. Steel structures being lighter and are thus more efficient to resist earthquake. On the other hand, they are more expensive (4 to 5 times). Theoretically, two structural elements having the same plastic moment have an equal failure or collapse load. Different profiles of IPE are realized in industry and all their characteristics are determined with a great precision (weight, geometrical characteristics and thus their plastic moment). Determining equivalent rectangular singly reinforced concrete cross-sections is not easy and seems impossible to be solved analytically. To a given profile it may be found a multitude of equivalent rectangular reinforced concrete cross-section (singly and doubly reinforced with different yield strengths and compositions of concrete). To take into consideration all these factors, it is absolutely necessary to construct three axis design charts with an appropriate choice of system of coordinates in order to cover all possible ranges of different parameters. The choice of all these possible rectangular reinforced concrete sections is governed by the plastic performance of these later. They must be under reinforced, allowing plastification of steel before failure in order to permit the redistribution phenomenon in plastic analysis. The exploitation of these different charts has revealed that the absolute majority of these rectangular reinforced concrete cross-section are reasonably well designed and are in conformity with the dimensions used in practice. The results of the present characterization using Eurocode 2 characteristics are compared to those of CP110. The impact does not seem to be very relevant.

Published: April 2021

S-Curve analysis in the construction interpreted as managing project with knowledge and traceable in the context of sustainable construction while displays the cumulative costs, labour hours or other quantities plotted against time. In the contract administration, delays in completing a construction project led to the breach of contract but, in contracts itself allow the construction period to be extended where there are delays that are not the contractor's fault. Under those circumstances, a presentation of a case-study regarding the analysis of S-Curve of a life project drew comparative interpretation of project performance towards project delivery schedule has been conducted in private initiative project. This study aims to investigate and examine the factors that cause delays in construction projects from the perspective of S-curve representations. The paper aims to provide in depth light about the existing causes of project delay and describe the key sources of financing problem and identify the consequences of contraventions of contract. Two distinct parts divided which are refers to the methods used to assess the perceptions of clients, consultants, and contractors on the relative importance of causes of delay in a project and referred to the procurement and documentation to analyse the delay. As a result, an Extension of Time (EOT) granted and identically changed the progress towards extension time where better planning demanded for improvement and restoration progress kept on track. This paper presented a practical and comparative S-Curve within extension of time to ensure delivery of project on schedule. In the long run, the identified causes are combined into 16 factors. Finally, the result of this match was brought in order to critically understand and provide a guideline to contractor in preparing EOT application and choose reliable factor based on the specific circumstances of project delay factors thorough review conducted to reveal the nature of EOT application techniques.

Study of Head Loss in Rapid Filtration with four River Sands
Authors: Agbo Komitse Edoh , Ayité Yawovi M. X. Dany , Pachoukova Irina 
Published: April 2021

In this work, we studied the filtration behavior, with regard to the head loss, of four calibrated Togo Rivers sands compared to that of a reference filter sand imported from Europe. The objective is to determine the suitability of local rivers sands as filter sands for water treatment plants. The sands were successively loaded into a filtration pilot and subjected, during at least 20 hours, to the filtration of water whose turbidity was maintained at around 20 NTU. The results show that the average deviations of the head loss profiles as a function of depth, calculated in relation to the head loss recorded on the reference sand, at the same filtration time t=20h, are small and vary from 2 cm to 8 cm. In the same way, the curves of the head loss as a function of time are quite close to the one observed for the reference sand. Examination of the clogging front after 20 hours of filtration reveals that the progression is either the same or greater and reached 20 cm in depth at the same time. This study can be extended to other rivers sand samples and by varying the turbidity and the filtration rate. Doi: 10.28991/cej-2021-03091682 Full Text: PDF

Understanding the influence of various variables on surface water quality is extremely important for protecting ecosystem health. The principal aim of this study is to assess the direct (DE), indirect (IE) and total effects (TE) of socio-economic, terrestrial and hydrological factors on surface water quality via path analysis through the lens of 15 sub-basins located on Indus basin, Pakistan. Four path models were selected based on Comparative Fit Index (CFI) = 0.999 value. First path model showed that rangelands having low population density decline river runoff which decreases instream Electrical Conductivity (EC) because of lower anthropogenic activities. Second path model depicted that croplands having higher population density enhance river runoff due to irrigation tail water discharge which decline instream EC because of dilution. Third path model showed that croplands with higher population density enhance river runoff which increases instream NO3 concentration because of unscientific application of irrigation water. Fourth path model unveiled that croplands enhance Gross Domestic Product (GDP) which enhance river runoff and instream NO3 concentration. To protect ecosystem health, Best Management Practices (BMPs), precision farming and modern irrigation techniques should be adopted to reduce irrigation tail water discharges containing pollutants entry in Indus River.
