Published: July 2020

Background:

Perineural invasion (PNI) and spread are one of the grimmest prognostic factors associated with primary skin and head-and-neck cancers, yet remain an often confused, and underreported, phenomenon. Adding complexity to reaching a diagnosis and treating perineural spread (PNS) is the finding that patients may have no known primary tumor, history of skin cancer, and/or incidental PNI in the primary tumor. These delays in diagnosis and treatment are further compounded by an already slow disease process and often require multidisciplinary care with combinations of stereotactic radiosurgery, surgical resection, and novel treatments such as checkpoint inhibitors.

Methods:

Six patients with metastatic cancer to the cranial nerves who underwent Gamma Knife radiosurgery (GKRS) treatment were chosen for retrospective analysis. This information included age, gender, any past surgeries (both stereotactic and regular surgery), dose of radiation and volume of the tumor treated in the GKRS, date of PNS, comorbidities, the patient follow-up, and pre- and post-GKRS imaging. The goal of the follow-up with radiographing imaging was to assess the efficacy of GKSS.

Results:

The clinical course of six patients with PNS is presented. Patients followed variable courses with mixed outcomes: two patients remain living, one was lost to follow-up, and three expired with a median survival of 12 months from date of diagnosis. Patients at our institution are ideally followed for life.

Conclusion:

Given the morbidity and mortality of PNS of cancer, time is limited, and further understanding is required to improve outcomes. Here, we provide a case series of patients with PNS treated with stereotactic radiosurgery, discuss their clinical courses, and review the known literature.
Massive Secondary Cutaneous Meningioma with Extension to the Face
Authors: Elarjani Turki , Alhuthayl Meshari , Hassounah Maher
Published: July 2020

Background:

Cutaneous meningioma is a very uncommon pathologic entity that can be divided into primary and secondary types. Secondary cutaneous meningioma arises from an intracranial meningioma through metastasis, seeding during surgery, or direct bone invasion. There are limited published case reports correlating the development of cutaneous meningioma to high-grade convexity meningioma.

Case Description:

A 63-year-old man underwent total resection of a right frontal convexity meningioma, World Health Organization Grade I in 2001. He presented in 2016 with a small frontal cutaneous mass over the craniotomy site. Computed tomography showed extracranial and intracranial components of the meningioma. The patient declined surgical intervention and lost to follow. One and half years later, he underwent resection of the growing ulcerating cutaneous component in an outside hospital. The pathological diagnosis was Grade 3 meningioma. Six months later, he presented to us with a massive cutaneous meningioma and large intracranial component. Surgical resection and multidisciplinary management were planned. The patient was very hesitant to have surgery but settled for receiving radiation. Seven months after radiation, he presented with a decreased level of consciousness and skin necrosis with maggot infestation. His code status was changed to “do not attempt resuscitation,” and he died 3 days later in December 2019.

Conclusion:

Large intracranial meningiomas with massive transosseous extension to the scalp pose a significant challenge to the treating team. Proper planning and a multidisciplinary approach are essential. However, prognosis remains generally poor.
A case of aphasia due to temporobasal edema: Contemporary models of language anatomy are clinically relevant
Authors: Surbeck Werner , Gerardy Francois , Moura Aude Barjona Morgado De , Deprez Louis , Martin Didier , Scholtes Felix
Published: July 2020

Background:

Understanding the anatomy of language in the human brain is crucial for neurosurgical decision making and complication avoidance. The traditional anatomical models of human language, relying on relatively simple and rigid concepts of brain connectivity, cannot explain all clinical observations. The clinical case reported here illustrates the relevance of more recent concepts of language networks involving white matter tracts and their connections.

Case Description:

Postoperative edema of the ventral occipitotemporal cortex, where modern network models locate a crucial language hub, resulted in transient severe aphasia after a subtemporal approach. Both verbal comprehension and expression were lost. The resolution of edema was associated with complete recovery from phonetic and semantic dysfunction.

Conclusion:

Complete aphasia due to a functional disturbance remote from the areas of Broca and Wernicke could be explained by contemporary neuroanatomical concepts of white matter connectivity. Knowledge of network-based models is relevant in brain surgery complication avoidance.

Diabetes is one of the most common metabolic disturbances associated with carbohydrates, lipids, proteins and relative or absolute insulin depletion. Hyperglycemia in type 2 diabetes (T2DM) leads to the increased lipid and decreased total antioxidant capacity followed by development of chronic complications due to oxidative stress. Cumin is one of the medicinal herbs which are being studied for antioxidant, antibacterial and effects. purpose of this study was to evaluate the effect of cumin on status, oxidative stress and antioxidant capacity in patients with T2DM. Two hundred patients with T2DM were selected in the randomized control trial, of which 100 subjects were enrolled as the study group was given 500 mg of cumin powder in capsule form daily along with their drug medication () for 3 months period while 100 subjects on medication of drug () were selected as the control group. Fasting plasma glucose, serum levels of lipid in the form of (MDA) and Total Antioxidant Capacity (TAC) were measured at baseline and also after a period of 3 months intervention period. The result showed a significant reduction in fasting plasma glucose level (FPGL), serum MDA and significant rise in serum TAC in study group by the end of 3 months of cumin supplementation period. Supplement action of cumin leads to improve , antioxidant and decrease oxidative stress in type 2 diabetes patients and could be useful in the management of T2DM.

Holoprosencephaly has a sever condition called Cylopia that is occur due to embryonic prosencephalon cleavage failure and contrast. Mostly cylopia form is holoprosencephaly, mid facial tissue is absent which causes the one eye on a single orbit. It is a sever deformity of median faciocerebal development. There are 1.05 cases in100,000 birth, still births of cyclopean. Abnormal nose above eyes or absence of nose, single eyes or half divided eyes in single orbit are features of cyclopia, where as reduced size of oral aperture or absence of mouth, absence of mandible with ears below chin. It is as etiologically heterogeneous condition, which can be caused by genetic mutation, chromosomal defect and teratogenic environmental factors. Environmental factors can be diabetic embryopathy, retinoic acid, several anecdotal suggestion of teratogenic factor for HPE, which includes salicylates and viruses. Some list of syndrome are also involved to cause cyclopia Like steinfeld syndrome, dysgnathia complex,Pseudotrisomy 13 syndrome and Smith–Lemli– Opitz syndrome. On other hand inborn abnormalities also cause cyclopia but its come under chromosomal syndrome. Anatomical detection can be done by brain MRI, whereas in prenetal diagnosis, sonography is more significant. Ultrasound also used early detection can be done and knowledge of sonographic finding soectrum leads to accuracy of prenatal diagnosis of cyclopia. After birth the chromosomal study helps to diagnose cyclopia along with postmortem biopsy.

Preservatives are used in a wide field of application to maintain the quality of products. They are used to deal with the chemical, physical and microbiological problems and the constraints of the development of several formulations. In this work, we tested the stability of antimicrobial preservatives which are the parabens under different stress degradation conditions to evaluate their degree of effectiveness. The tested parabens were incubated in different solutions at different pH, Temperatures, light conditions, and presence or absence of sucrose in solution (create a medium similar of syrups). The HPLC was used for the assay, by a validated method for the parabens assay and the statistical analysis of the data is carried out by JMP software. The results show a direct influence of temperature and pH on the level of parabens, while the influence of light remains negligible. The increase in temperature gives a degree of immunity of parabens levels, especially with the extreme values of pH. This study is one of the first studies of forced decomposition of parabens carried out under the various conditions suggested. The results give an idea of the stability profile of the tested parabens and suggest a model of the conditions of conservation and use of these products in different domains and under different conditions.

Authors: Saumya Das  , Aukunuru Jithan  , Raghunadha Gupta
Published: July 2020

The bioavailability of the drug is mainly governed by factors like partition coefficient, solubility Pka, etc. The modification of these physicochemical properties can be done to enhance the bioavailability and thus effective therapy can be achieved. This research deals with the advantages of co-crystals over salts, solvates (hydrates), solid dispersions and polymorphs. A pharmaceutical co-crystal is a single crystalline solid that incorporates two neutral molecules, one being an active pharmaceutical ingredient (API) and the other a co-crystal former. In the present study co-crystals of Metformin Hydrochloride and Glimepiride were prepared using different co-formers. Different ratio of urea, succinic acid and tartaric acid were used to design the co-crystals. They were formulated by two different methods- cooling crystallization and solvent evaporation. The prepared co-crystals were evaluated for microscopic characters, product yield, Fourier Transform Infrared Spectroscopy, Micromeretic properties, drug content, dissolution study of co-crystals, stability studies. The results indicated that co-crystals prepared by using a suitable co-former can definitely enhance the dissolution rate ultimately leading to enhanced bioavailability. Out of three co-formers used to design the co-crystals, succinic acid is found to be more effective. Moreover the bioavailability of Glimepiride is more enhanced as compared to Metformin Hydrochloride as it belongs to BCS class II.

Authors: Kala Barathi S  , Merlin P
Published: July 2020

Pain is an undesirable tactile and emotional experience related with real or potential tissue harm. Pain prompts people to seek health care more often than any other symptom. It is one of the most important areas of care because people cannot function fully when they are in pain. Pain prompts people to seek health care more often than any other symptom. Painful procedures in the hospital are blood collection, intramuscular injection and intravenous injection etc. this procedural pain is relieved by non pharmacological measures. Procedural pain is the most common cause for pain during provision of nursing care. So as the part of nursing profession, it is our responsibility to use effective strategies to reduce procedural pain. Especially in infant’s routine immunization, bruises and childhood illness mean that pain is a part of everyday experiences of all children and infants. Because infants cannot describe their pain and emotions, it is important to observe the behavioural response of the children to assess the pain. So the present study is done to determine the effectiveness of manual pressure on lumbar region to reduce pain during intramuscular injection among infants in selected hospital, Thiruvalur. Quantitative approach with quasi experimental design was adopted to conduct this study with 60 infants who were selected with purposive sampling technique. The data was collected using structured questionnaire to assess the demographic variable and FLACC pain rating scale for assessing the pain level. The results of the study are out of 60 samples (56.6%) had moderate pain and (43.4%) had mild pain in the experimental group.

Authors: Saja S. Falih  , Falah S. Al-Fartusie  , Noor T. Tahir
Published: July 2020

Short stature is a general term that usually accompanies a lack of growth hormone among people, and is more common among children. In this study, some kidney functions and lipid profile tests were evaluated in children and adolescents with short stature to find any relationship between the disturbance in these parameters and the etiology of short stature. A total of 60 short stature patients with a growth hormone deficiency, age range between 4-18 years, along with 60 age-matched healthy volunteers, were included in this study. Serum levels of GH, IGF-1, urea, and creatinine, as well as lipid profile, were determined, and then statistical analysis was performed on the collected data. The obtained results indicated a significant decrease in serum levels of GH and IGF-1 (p <0.01) in patients compared to control values. The results also indicated a substantial increase in serum levels of triglycerides and VLDL, mainly seen in children, and reported non-significant differences in HDL, LDL, and urea levels for GHD patients compared to control values. Additionally, the results showed a significant increase in the creatinine level of adolescent patients only. This study concluded that there is a clear relationship between disturbances in creatinine levels and the promotion of GHD in short stature patients. Current work has demonstrated that anomalies in the lipid profile, especially triglycerides and VLDL, are closely related to the causes of short stature. Finally, and most importantly, we can suggest that triglycerides and VLDL may help identify patients at an early age who are at risk of short stature, especially children.

This article provides insight into an emerging research discipline called Psychoinformatics.In the context of Psychoinformatics, we emphasize the co-operation between the disciplines of Psychology and Information Science which handles large data sets is derivative from severely used devices like smartphones or any online social networking in order to highlight  sychological qualities including both personality and mood. New challenges await psychologists considering the result “Big Data” sets because classic psychological methods will only in part be able to analyze this data derived from ubiquitous mobile devices as well as other everyday technologies. Consequently, psychologist must enrich their scientific methods through the inclusion of methods from informatics. Furthermore, we also emphasize on data which is derived from Psychoinformatics to combine in a such a way to give meaningful way with data from human neuroscience. We close the article with some observations of areas for future research and problems that require consideration within this new discipline.

Novice Programmers’ Coping with Multi-Threaded Software Design
Authors: Rashkovits Rami , Lavy Ilana
Published: July 2020

Aim/Purpose: Multi-threaded software design is considered to be difficult, especially to novice programmers. In this study, we explored how students cope with a task that its solution requires a multi-threaded architecture to achieve optimal runtime.

Background: An efficient exploit of multicore processors architecture requires computer programs that use parallel programming techniques. However, parallel programming is difficult to understand and apply by novice programmers.

Methodology: The students had to address a two-stage problem: (1) design an optimal runtime solution to a given problem with no additional instructions; and (2) provide an optimal runtime multi-threaded design to the same problem. Interviews were conducted with a representative group of students to understand the underlying causes of their provided designs. We used qualitative research methods to gain refined insights regarding the students’ decision making during the design process. To analyze the gained data, we used content analysis tools.

Contribution: The case study presented in this paper will help the teacher to stress the merits and limitations of various parallel architectures and confront students with the consequences of their solutions via performances’ benchmark.

Findings: Analysis of the student’s solutions to the first stage revealed that the majority of them did not provide a multi-threaded solution ignoring the optimal runtime requirement. At the second stage, seven various architectures were provided differing in the number of involved threads, the data structures used, and the synchronization mechanism employed. The majority of the solutions were sub-optimal and only a few students provided an optimal one.

Recommendations for Practitioners: We recommend conducting class discussions that will follow a task similar to the one used in this study.

Recommendation for Researchers: To be able to generalize the received results this research should be repeated with larger study participant groups from various academic institutions.

Impact on Society: Understanding the difficulties of novice programmers may lead to quality software systems.

Future Research: To be able to generalize the received results this research should be repeated with larger study participant groups from various academic institutions.

The study was carried out to analyze the compliance status of NBC and Byelaws in private housing construction of Tilottama Municipality. The permitted building samples with all necessary documents is taken for research purpose to trace the compliance status of National Building Code and Byelaws in construction of private housing.

Field verification and review of approved drawings and building permits of 51 numbers of households from the total population of 323are selected by purposive sampling method to check the compliance status of NBC and Byelaws provisions. The samples are taken from both ProfessionallyEngineeredBuildingsandMandatoryruleofthumb-(NBC205) buildings constructed in the Tilottama Municipality.

From the study, it is found that after the earthquake concerned stakeholders possess good knowledge of earthquake and its consequences. Knowledge regarding the earthquake resistant design and construction process is found fairly adequate. The perspective of concerned stakeholders towards building code and byelaws are positive. Out of 51 households surveyed, only 7 of the buildings have not complied with all the technical requirements of NBC whereas the building byelaws provisions are found to be effectively implemented by 44 buildings. The adopted process and existing mechanism for the implementation of building code and byelaws by the municipality is not effective as the tracking system of building permit process is ineffective.

Investigating students understanding of organic reaction mechanisms from performing organic chemistry experiments
Authors: Mistry Nimesh , Nicholson Stephen
Published: July 2020

The use of laboratory work to improve students’ knowledge of theory is one that is disputed. Student reflections of what they learn during practical work repeatedly show that students rarely think about theory. There is a lack of data that objectively compares students’ knowledge of theory where they complete an associated experiment to when they do not in order to understand if practical work does effect students’ knowledge of scientific concepts. In this work we aimed to address this gap by investigating the effect of students’ knowledge of organic mechanisms where they both perform and associated experiment and where they did not. Our results showed that organic chemistry experiments had no effect on students’ knowledge of organic mechanisms. These results support the view that there is little evidence to support the use of laboratory work to aid understanding of theory.

In an undergraduate programming class taught at Nanyang Technological University, Singapore, students (N=243) were given an opportunity to grade reports submitted by their peers. 10% of all students participated in peer grading and were satisfied with the grade given to them by peers (i.e., this group did not use instructors’ resources). 13% participated in peer grading, updated their reports based on peer feedback, and submitted to a course tutor for final grading. We have shown that even though students who participated in peer grading and updated their reports achieved higher scores, but it happened because they were stronger students to begin with. At the same time, scores of students who participated in peer grading and did not re-submit their reports to an instructor were not lower than average scores. Thus peer grading can be recommended in teaching programming classes as a strategy that reduces instructors’ workload while not jeopardizing students’ learning.

Published: July 2020

In architecture, interlace structural concept is considered as a new design approach for cosmopolitan cities with high density to minimize the land use and increase the interaction. With various architectural approach, land resources can be minimized by this interlace concept for residential complexes. Such buildings will eliminate the reduction of land resource problem and on the other side safety measures in structural design is incorporated by interlace concept of buildings. This new concept can be constructed steel or reinforced concrete. In this paper, an analytical approach has been presented for these buildings in architecture and structural design. In the research, design considerations were taken for interlaced structures with reinforced concrete and steel. Components of steel structure, isolated footing, and columns. This paper is presenting a step wise process for interlance structures. They are identification of project area, layout and model preparation, analysis and design of concrete interlaced structure, analysis and design of steel interlaced structure, drafting of the plans and costing and estimation of the structures. Comparison of both reinforced concrete and steel structures were carried out. The main aim of the paper is to provide a comparison between steel and concrete interlaced structure. A cost estimation was carried out to determine optimum design and construction for interlaced structures.

Remote sensing of submerged aquatic vegetation: an introduction and best practices review
Authors: Rowan Gillian , Kalacska Margaret
Published: July 2020

Submerged aquatic vegetation (SAV) is a critical component of aquatic ecosystems. It is however understudied and rapidly changing due to global climate change and anthropogenic disturbances. Remote sensing can provide the efficient, accurate and large-scale monitoring needed to ensure proper SAV management. Our objective is to introduce remote sensing to researchers in the field of aquatic ecology. Applying remote sensing to the underwater environment is more complex in comparison to terrestrial studies due to the water column. A wide range of sensors and platforms from remotely operated vehicles to satellites are available for use in the underwater environment, a sample of which being presented herein. The utility of any sensor/platform combination varies depending on the aquatic conditions being observed. An overview of the required corrections, processing, and analysis methods for passive optical imagery is presented and discussed. Previous applications of remote sensing to identify and detecting SAV are briefly presented and notable results and lessons are discussed.
