Cone beam computed tomography-guided differences among registration methods for lung cancer and the effects of tumor position,treatment model,and tumor size on positioning errors

Objective To explore the differences in three different registration methods of cone beam computed tomography(CBCT)-guided down-regulated intense radiation therapy for lung cancer as well as the effects of tumor location,treatment mode,and tumor size on registration.Methods This retrospective analysis included 80 lung cancer patients undergoing radiotherapy in our hospital from November 2017 to October 2019 and compared automatic bone registration,automatic grayscale(t+r)registration,and automatic grayscale(t)positioning error on the X-,Y-,and Z-axes under three types of registration methods.The patients were also grouped according to tumor position,treatment mode,and tumor size to compare positioning errors.Results On the X-,Y-,and Z-axes,automatic grayscale(t+r)and automatic grayscale(t)registration showed a better trend.Analysis of the different treatment modes showed differences in the three registration methods;however,these were not statistically significant.Analysis according to tumor sizes showed significant differences between the three registration methods(P<0.05).Analysis according to tumor positions showed differences in the X-and Y-axes that were not significant(P>0.05),while the autopsy registration in the Z-axis showed the largest difference in the mediastinal and hilar lymph nodes(P<0.05).Conclusion The treatment mode was not the main factor affecting registration error in lung cancer.Three registration methods are available for tumors in the upper and lower lungs measuring<3 cm;among these,automatic gray registration is recommended,while any gray registration method is recommended for tumors located in the mediastinal hilar site measuring<3 cm and in the upper and lower lungs≥3 cm.

Efficiency of locally available filter media on fluoride and phosphate removal for household water treatment system

Since conventional water treatment is not affordable in developing countries,looking for locally available and alternative treatment options is mandatory.Removal of fluoride and phosphate can be achieved by designing appropriate filtration media from different materials such as sand,calcined clay,pumice,scoria and bone char.This study was designed to determine the removal efficiency of these locally available filter media with respect to detention time and pH.The filtration apparatuses(tank) were filled separately with stone,gravel with grain size 0.6-4.75 mm and 40 cm deep,sand(ES = 0.15—0.35 mm and UC = 1.5-3),calcined clay,pumice,scoria and bone char with grain size 0.25-0.5 inch.Water samples were prepared using glass bottles with fluoride concentrations of 6 and 8 mg/1 and phosphate concentration of 4 mg/1.Laboratory analysis was carried out before and after filtration to determine the removal efficiency of each medium.It was found that the highest removal of fluoride was achieved by bone char(89.65%),followed by pumice(82.4%).However,bone char has rather increased the concentration of phosphate by 63.8%.Sand was the most efficient media to remove phosphate,managing to remove by 70%.Therefore,it is an attractive option to use these locally available,environmental friendly and appropriate technologies for efficient removal of both fluorine and phosphate at the household or community water treatment level.

FEM simulation and experimental verification of temperature field and phase transformation in deep cryogenic treatment

Combining with the low temperature material properties and the boiling heat transfer coefficient of specimen immersed in the liquid nitrogen, a numerical model based on metallo-thermo-mechanical couple theory was established to reproduce the deep cryogenic treatment （DCT） process of a newly developed cold work die steel Cr8Mo2SiV （SDC99）. Moreover, an experimental setup for rapid temperature measurement was designed to validate the simulation results. The investigation suggests that the differences in temperature and cooling rate between the surface and core of specimen are very significant. However, it should be emphasized that the acute temperature and cooling rate changes during DCT are mainly concentrated on the specimen surface region about 1/3 of the sample thickness. Subjected to DCT, the retained austenite of quenched specimen continues to transform to martensite and finally its phase volume fraction reduces to 2.3%. The predicted results are coincident well with the experimental data, which demonstrates that the numerical model employed in this study can accurately capture the variation characteristics of temperature and microstructure fields during DCT and provide a theoretical guidance for making the reasonable DCT procedure.

NUMERICAL SIMULATION OF FORGING AND SUBSEQUENT HEAT TREATMENT OF A ROD BY A FINITE VOLUME METHOD

A method to simulate processes of forging and subsequent heat treatment of an axial symmetric rod is formulated in eulerian description and the feasibility is investigated. This method uses finite volume mushes for troching material deformation and an automatically refined facet surface to accurately trace the free surface of the deforming material.In the method,the deforming work piece flows through fixed finite volume meshes using eulerian formulation to describe the conservation laws,Fixed finite volume meshing is particularly suitable for large three-dimensional deformation such as forging because remeshing techniques are not required, which are commonly considered to be the main bottelencek in the ssimulations of large defromation by using the finite element method,By means of this finite volume method, an approach has been developed in the framework of 'metallo-thermo-mechanics' to simulate metallic structure, temperature and stress/strain coupled in the heat treatment process.In a first step of simulation, the heat treatment solver is limited in small deformation hypothesis,and un- coupled with forging. The material is considered as elastic-plastic and takes into account of strain, strain rate and temperature effects on the yield stress.Heat generation due to deformation,heat con- duction and thermal stress are considered.Temperature - dependent phase transformation,stress-in- duced phase transformation,latent heat,transformation stress and strain are included.These ap- proaches are implemented into the commerical commercial computer program MSC/SuperForge and a verification example with experimental date is given as comparison.

Effect of microwave treatment on tensile properties of sugar palm fibre reinforced thermoplastic polyurethane composites

The effect of microwave treatment on the tensile properties of treated sugar palm fibre with 6% NaOH reinforced thermoplastic polyurethane composites was investigated. Firstly, the sugar palm fibres were treated by 6% alkali solution. Then, microwave treatment was used to treat the alkali treated sugar palm fibres. Three types of temperatures(i.e. 70, 80 and 90℃) were applied in microwave treatment. The extruder and hot press machines were used to mixing the sugar palm fibres and polyurethane resin, and fabricate the composites. Tensile properties(i.e. tensile strength, tensile modulus and elongation at break) were studied by following the ASTM D-638 standard. The highest tensile strength was recorded 18.42 MPa with microwave temperature at 70℃ and 6% alkali pre-treatment. Therefore, the temperature 70℃ of microwave treatment may consider the best degree cent grate.

Gastric cancer with peritoneal metastases: Efficiency of standard treatment methods

BACKGROUND Peritoneal metastasis(PM),arising from gastric cancer(GC),is the most common pattern of synchronous and metachronous dissemination and is generally associated with poor prognosis.New therapeutic modalities are being increasingly employed for such patients.AIM To develop more advanced methods,it becomes necessary to study the results of existing standard treatment methods in patients with PM in order to perform a comparative analysis of the strategies.METHODS A retrospective analysis of the efficiency of standard treatment methods(i.e.,palliative chemotherapy,palliative gastrectomy,and the best supportive care)was performed on 200 GC patients with synchronous PM.RESULTS The overall survival(OS)rate in 200 GC patients with PM under standard treatment was 5.4 mo.One-year survival occurred in 18.4%of patients.In multivariate analysis,the survival rate was significantly influenced by the following factors:Presence of extraperitoneal metastases,and stage of PM according to both the Japanese Gastric Cancer Association(JGCA)and the peritoneal cancer index(PCI).The median OS and 1-year survival of patients withР1,P2,and P3(JGCA)carcinomatosis were 9.8 mo,6.7 mo,and 4.0 mo,and 47.2%,18.8%,and 5.1%,respectively.The application of the palliative gastrectomy resulted in an increase in the median OS by up to 17 mo compared to the conservative approach where the value was 8.5 mo(P=0.05)in patients withР1РМ.In patients withР3,palliative chemotherapy increased the OS by up to 5.6 mo compared to the OS of 3.2 mo(P=0.0006)for best supportive care.The median OS and 1-year survival of patients withРCI of 1-6,7-12 and 13+points were 8.5 mo,4.2 mo,and 4.1 mo,and 39.8%,6.7%,and 5.5%,respectively.Palliative gastrectomy increased the median OS to 12.6 mo compared to conservative approach of 8.0 mo(P=0.03)in patients withРCI of 1-6 points.In patients withРCI 13+points,only palliative chemotherapy increased the OS to 6.0 mo compared to the OS of 3.4 mo for best supportive care(P=0.0008).CONCLUSION GC patients with PM are characterized by extremely poor prognoses.Long-term survivors were found in the group with PCI of 1-6 points,and there was no survival difference in groups with PCI 7-12 vs PCI 13+points.Palliative gastrectomy could prove effective in treating patients with early stage PM.The three standard treatment methods are equally effective for moderate stages of PM.In cases with advanced peritoneal carcinomatosis,a significant increase in prognosis was registered only after treatment with palliative chemotherapy.

An Alternative Regression-Based Approach to Estimate the Crash Modification Factors of Multiple Treatments Using Before-and-After Data

Before-and-after methods have been effectively used in the road safety studies to estimate Crash Modification Factors (CMFs) of individual treatments as well as the multiple treatments on roadways. Since the common practice is to apply multiple treatments on road segments, it is important to have a method to estimate CMFs of individual treatment so that the effect of each treatment towards improving the road safety can be identified. Even though there are methods introduced by researchers to combine multiple CMFs or to isolate the safety effectiveness of individual treatment from CMFs developed for multiple treatments, those methods have to be tested before using them. This study considered two multiple treatments namely 1) Safety edge with lane widening 2) Adding 2 ft paved shoulders with shoulder rumble strips and/or asphalt resurfacing. The objectives of this research are to propose a regression-based method to estimate individual CMFs estimate CMFs using before-and-after Empirical Bayes method and compare the results. The results showed that having large sample size gives accurate predictions with smaller standard error and p-values of the considered treatments. Also, results obtained from regression method are similar to the EB method even though the values are not exactly the same. Finally, it was seen that the safety edge treatment reduces crashes by 15% - 25% and adding 2 ft shoulders with rumble strips reduces crashes by 25% - 49%.

The Pathogenetic Concept of the Diagnostic-Treatment Approach for Patients with Purulent-Septic Complications

Background: The significant improvement of immediate and long-term functional results of treating patients is the fundamental problem of modern medical science. A deep understanding of the pathogenesis is the key point in creating the management strategy for patients with various diseases. Information about the mechanisms of origin and development of purulent-inflammatory diseases and sepsis is essential for finding effective ways to prevent and treat them. The aim of the research is to use the method of fluorescence spectroscopy in creating the pathogenetic diagnostic and treatment model for the prevention and treatment of purulent-inflammatory diseases and sepsis, modification of treatment tactics, search for new markers of purulent-septic diseases, as well as monitoring of patients during the treatment. Materials and methods: The proposed approach, along with standard diagnostic methods, was used to organize the treatment process of 100 patients with purulent-inflammatory diseases, including 15 patients with sepsis, 35 with acute inflammatory abdominal pathology, 20 patients with burn injury (main group) and 35 patients with burn injury (comparison group). Results: The behavior of spectral-fluorescent characteristics in their dynamics has been studied, and the new markers for assessing patients’ conditions have been proposed. Their effectiveness for the diagnosis of purulent-septic diseases has been proved, which advances the results of standard research methods by 24 - 48 hours. Conclusions: The proposed diagnostic and treatment approach is fundamentally important for diagnosis and monitoring during the treatment of patients with purulent-septic diseases. Particularly relevant is the proposal to modify the treatment process for these patients, associated with the use of infusion of donor albumin solutions.

Different Detection and Treatment Methods for <i>Entamoeba histolytica</i>and <i>Entamoeba dispar</i>in Water/Wastewater: A Review

Entamoeba histolytica is an anaerobic parasitic protozoan and well known as a human pathogen, while its close relative, Entamoeba dispar, also possesses similar characteristics as an infectious agent. These microorganisms are generally transmitted in fecal-contaminated water. However, E. dispar present in industrial wastewater is also capable of creating biofilms that can cause adverse impacts in piping networks. Therefore, it is important to detect both of these protozoan species in water and to find a cost-effective technique for inactivation or management control. This review article summarizes the available detection methods in water and wastewater matrices along with feasible disinfection techniques.

Knowledge, Attitudes and Practices of the Population of the District of Ahomadégbé(Municipality of Lalo) in Benin on Methods of Water Treatment at Home

Water is an indispensable resource for life. In the district of Ahomadégbé in Benin, although most of the population has access to improved water sources, in their homes, residents consume poor water quality due to microbiological contamination during transport and storage. To identify necessary actions needed to improve household drinking water quality, the present study aims to analyze the knowledge, attitudes, and practices the district of Ahomadégbé’s population regarding household drinking water treatments methods. A study was conducted, where 377 residents were interviewed using an individual questionnaire and 82 participants were selected for eight focus groups to determine the population’s knowledge, attitudes, and practices. More than 65% of the district’s population knew some methods of water treatment at home. In practice, however, they lacked the knowledge to apply the different water treatment methods and only 6.1% of the population used at least one method of water treatment at home, even if it was not always adapted. The water treatment methods residents used were Alum (KAl(SO4)2·12 H2O, chemical decantation method), filtration on tissues, and disinfection by boiling. Ineffective home water treatment methods, such as oil and cresol were also used. The population is aware of water contamination during transport and storage. Unfortunately, most residents surveyed do not treat water before consumption, and those who treat it, use inappropriate methods. Thus, people must be made aware of the health benefits of using effective home water treatment methods and their correct use.

Functional physiotherapy method results for the treatment of idiopathic clubfoot

BACKGROUND Idiopathic clubfoot is a congenital deformity of multifactorial etiology.The initial treatment is eminently conservative;one of the methods applied is the Functional physiotherapy method(FPM),which includes different approaches:Robert Debré(RD)and Saint-Vincent-de-Paul(SVP)among them.This method is based on manipulations of the foot,bandages,splints and exercises adapted to the motor development of the child aimed to achieve a plantigrade and functional foot.Our hypothesis was that the SVP method could be more efficient than the RD method in correcting deformities,and would decrease the rate of surgeries.AIM To compare the RD and SVP methods,specifically regarding the improvement accomplished and the frequency of surgery needed to achieve a plantigrade foot.METHODS Retrospective study of 71 idiopathic clubfeet of 46 children born between February 2004 and January 2012,who were evaluated and classified in our hospital according to severity by the Dimeglio-Bensahel scale.We included moderate,severe and very severe feet.Thirty-four feet were treated with the RD method and 37 feet with the SVP method.The outcomes at a minimum of two years were considered as very good(by physiotherapy),good(by percutaneous heel-cord tenotomy),fair(by limited surgery),and poor(by complete surgery).RESULTS Complete release was not required in any case;limited posterior release was done in 23 cases(74%)with the RD method and 9(25%)with the SVP method(P<0.001).The percutaneous heel-cord tenotomy was done in 2 feet treated with the RD method(7%)and 6 feet(17%)treated with the SVP method(P<0.001).Six feet in the RD group(19%)and twenty-one feet(58%)in the SVP group did not require any surgery(P<0.001).CONCLUSION Our study provides evidence of the superiority of the SVP method over the RD method,as a variation of the FPM,for the treatment of idiopathic clubfoot.
