Authors: Chen Sophia Y. , Leeds Ira L. , Cerullo Marcelo , Jones Joyce L. , Buchwald Ulrike K. , Efron Jonathan E. , Gearhart Susan L. , Safar Bashar , Fang Sandy H.
Published: November 2019

Background: Anal cancer incidence is increasing in the US. Though formally established national anal cancer screening guidelines are nonexistent, many providers advocate screening to avoid late disease presentation. This study assesses the knowledge, attitudes, and practices of anal cancer screening among providers to identify the degree of variation and barriers to screening.
Methods: Healthcare providers from two academic medical centers and a statewide community primary care group were surveyed using a questionnaire adapted from the National Survey of Primary Care Physicians’ Recommendations and Practice for Cancer Screening. Descriptive statistics were performed to explore providers’ responses and Fisher’s exact test to explore variation.
Results: 86 providers completed the questionnaire (response rate 24.2%): 81.4% physicians, 18.6% advanced practitioners. 48.2% of respondents perform anal cancer screening. 5.8% correctly identified all high-risk patient factors. “HIV+ patient” was identified most frequently as high-risk (93.5%), “organ transplant recipient” (42.9%) least frequently. Anal pap test was the most recommended first-line screening test (76.6%) followed by digital anorectal exam (19.2%), HPV test (8.5%), and high-resolution anoscopy (HRA) (6.4%). Clinical evidence (72.3%) and national guidelines (70.2%) were most influential in guiding providers’ screening recommendations. Lack of qualified screening providers (34.1%), lack of patient follow-up after positive test results (22.7%), and patient non-compliance to initial screening (15.9%) were identified as “usual” barriers.
Conclusions: Anal cancer screening attitudes and practices vary among providers. Development of national practice guidelines that define a multidisciplinary team approach from primary care anal cancer screening to specialist referral for HRA may reduce screening variability.

Authors: Aly Ahmed , Noubi Radwan , Ragab Mahmoud , Abdelaziz Khalid , Howarth Simon , Smith Stuart
Published: November 2019

Background: Maximal surgical resection is thought to confer survival benefit for both high- and low-grade gliomas. Intraoperative imaging assists with achieving maximal surgical resection. Different intraoperative imaging modalities have been implemented, but intra-operative MRI has a high cost that may limit its uptake in resource scarce healthcare systems.
Objectives: This study aims to evaluate intraoperative ultrasound as a surrogate for intra and post-operative MRI for assessing the extent of resection of glioma.
Methods: A partially prospective comparative study, which compares a prospective cohort group with a historical control group. We evaluated 74 glioma patients, who all underwent surgery in a regional UK Neurosurgical centre between October 2013 and October 2017. The study population was divided into 2 groups based on the use of ultrasound to guide the resection. We compared the size of the lesion prior and after excision to evaluate the extent of resection and undertook comparison with post-operative MRI.
Results: The mean extent of resection on the ultrasound images was 96.1 % and 97.7 % on the postoperative MR. Using Spearman’s correlation; extent of resection on the ultrasound images was strongly correlated with the extent of resection on the postoperative MR images (P=value <0.001). The use of intraoperative ultrasound was associated with a significant increase in the number of patients in whom 95% or greater extent of resection was achieved (Fisher’s exact test P= value 0.033).
Conclusion: Intra-operative ultrasonography could provide a reliable and cheaper alternative to intraoperative MRI to improve the extent of resection in glioma surgery.

Authors: Aly Ahmed , Smith Fiona , Glancz Laurence J , Mccabe Alistair , Coventry Julie , Dawson Kelly , Boam Sadie , Smith Stuart
Published: November 2019

Background: Venous thromboembolic events (VTE) are common causes of morbidity and mortality in glioblastoma patients. Mutation in the isocitrate dehydrogenase 1 enzyme (IDH1) is frequent in secondary glioblastoma and results in altered metabolomics.
Objectives: This study evaluates whether IDH-1 status correlates with incidence of VTE in glioblastoma patients.
Methods: Observational study of 398 cases of patients with glioblastoma, who all underwent surgery in a regional Neurosurgical centre between April 2012 and December 2014. IDH -1 status and Tissue factor (F3) protein expression were assessed by immunohistochemistry. Deep venous thrombosis (DVT) and pulmonary embolism (PE) were diagnosed by Doppler ultrasound and pulmonary CT angiogram respectively.
Results: 336 cases were wild type (WT) IDH-1 (94.1%) and 21 cases were IDH-1 mutated (R132H) (5.9%). 51 patients had a thromboembolic event (15.3%), with all cases of VTE in WT IDH-1 tumours, a rate of 21.8% within this group. IDH-1 status had a significant correlation with VTE (p=0.033 Fisher exact test). As expected, mutant IDH was associated with prolonged patient survival (p=0.024 Log rank). The mean expression in IDH-1 wild type GBM was 7.14 and in R132h mutant GBM was 4.87 (log2 scale). This was highly statistically significant with a corrected P value of less than 0.0001.
Conclusion: A significant association exists between IDH1 status in glioblastoma patients and the risk of VTE. Patients with wild type IDH-1 appear at high risk of VTE and appropriate precautions should be considered

Authors: Cativo Albuquerque Caroline , Da Silva Oliveira Livia , Barbosa de Alencar David
Published: November 2019

This paper addresses electric power as a relevant factor in the development of a region. For this reason, it highlights the importance of electricity in hard-to-reach communities, since the absence of electricity impacts the economic, social and political aspects. Aiming at rural electrification of low-income and isolated communities, the federal government created the Luz Para Todos program, since access to public energy is the right of the Brazilian citizen and social exclusion is vetoed by existing laws in the country. In this sense, the main objective of this study is to find a possible viable alternative for interconnecting the Costa do Parú communities to the local utility. For this, an analysis of the communities will be done to map the real conditions that portray importance and the necessity of the use of electricity among the families of the community. In addition, a survey will be conducted with the local utility about the Light for All program for the region. A model of photovoltaic system for the region will be elaborated based on surveys made with companies operating in the solar energy area. In the development of the research, it was found the various ways used in the Light for All Program to bring electricity to hard-to-reach regions, as well as the difficulties presented by the community for direct interconnection by the local utility. Relevant results were obtained about the real electric power conditions of the families. Based on this, a photovoltaic system model was designed for a possible LPT project that would meet the local needs of families. It is proposed that the maintenance of the off grid photovoltaic system be carried out by the local power utility.

The Problem of Two Bodies with a Finite Velocity of Gravity
Authors: Slyusarchuk Vasyl
Published: November 2019

From the moment of Newton’s discoveryof the law of universal gravitation, ordinary differentialequations were used to study the motion of bodies,since it was assumed that the velocity of gravitationis infinite. However, in reality the velocity of gravityis finite, which is consistent with the theory of relativityof Einstein, which postulated that the velocity ofgravity matches the velocity of light, and the studiesconducted by S. Kopeikin and E. Fomalont on the fundamentallimit of the velocity of gravity. Due to thedelay of the gravitational field for studying the motionof bodies, the mathematical apparatus based on differentialequations with a delay argument is the mostacceptable one. These equations are used to constructand study the mathematical model of the motion of twobodies. It is shown that the motion of these bodies withidentical masses (with finite velocity of gravity!) is notcarried out in accordance with Kepler’s laws.

Using the density functional theory approach and pseudopotentials we studied energetics and electron structures of metal layers (Al, Cu, Ni, and Cr) deposited on a cristobalite surface. We have found that the properties of the first adsorbed layers decide by interaction of metal atoms with oxygen atoms of a substrate surface. Aluminum as an easily oxidized metal, is characterized by the high adhesion, it is followed by nickel and chromium, and copper closes the studied group of metals. Further plating is characterized by significant reduction of binding energy; the properties of films tend to properties of bulk metals

In diesem Beitrag wird ein texthandlungsorientiertes Analyseverfahren zur sprachwissenschaftlichen Erforschung des Nation Branding in digitalen Medien vorgestellt. Der hier vertretene Ansatz, der eine eklektische Weiterentwicklung verschiedener pragmatischer Text- und Sprechhandlungskonzepte
(Rothkegel, Von der Lage-Müller, Brinker) ist, unterscheidet drei hierarchisch angeordnete Handlungsebenen, und zwar Texthandlung oder Textthema (’die in Frage kommende Nation besprechen‘), Teiltexthandlung oder Teilthema (die genaue Realisierung der Texthandlung durch verschiedene
sekundäre Handlungen, zum Beispiel ’die Lage der spanischen Wirtschaft bewerten‘) und die partielle oder tertiäre Teiltexthandlung (eine aus der Sentiment Analysis stammende Kategorie, die Teil- texthandlungen anhand ihrer Polarität klassifiziert, zum Beispiel ’die
Lage der spanischen Wirtschaft positiv bewerten‘). Die Durchführbarkeit des hier vorgestellten Texthandlungskonzepts wird empirisch in einer Pilotuntersuchung zum Bild Spaniens in der deutschen Presse und im sozialen Netzwerk Facebook evaluiert.

Abstrack: Type of roof, temparature and humidity in the house. The roof is the largest element that receives sun exposure. The type of roof affects the amount of heat energy that can be absorbed of reflected. The temperature and humidity in the room.This study aims to determine the relationship between the type of roof with temperature and humidity in the house in the Badaun village. This research use cross sectional design with variation of roof type was leaf, asbestos and iron sheeting. The study population was 68 houses and was analyzed using Somers'd test.The results showed that the proportion of leaf roof, asbestos and iron sheeting were 36.8%, 10.3% and 52.9%, respectively. Average home room temperature using a leaf roof type of 29.6°C, 32°C asbestos roof and 32.1°C iron sheeting roof. The average humidity of the house that uses the leaf roof is 72.28%, asbestos 55.7% and iron sheeting 57.3%. The results of the analysis using the Somers'd test proved statistically there is a strong relationship between the type of roof of the house (leaves, asbestos and zinc) with the temperature and humidity in the house in Badaun Village, Tapin District. Every home that uses zinc and asbestos roof 27 times the risk (OR = 27) hotter than the house using a leaf roof. Efforts that can be done to cope with higher temperatures and humidity is in the effort to install the ceiling of the house and always open the doors and windows every morning.

Abstract: Toxicity Test Of Acute Industrial Waste Water On Tilapia Fish (Oreochromis Niloticus). The sasirangan industrial liquid wastes containing high ammonia and high pH when discharged into the receiving water body without treatment will result in changes in water quality and even the death of aquatic biota so that an acute toxicity test is necessary. This study aims to determine the value of LC50 from waste sasirangan against tilapiaI. This research used the experimental method of Post Control Only Control Group Design design. Samples taken as much as 100 liters of waste in one industry sasirangan existing in the city of Banjarmasin. Concentrations of the sasirangan waste solution to be used in the acute toxicity test are: 4, 8, 12, 16 and 20%. Parameters studied include ammonia, DO, pH, and temperature. To determine the value of LC50 using probit analysis. The results showed that LC50 for exposure time 24, 48, 72 and 96 hours were 14.73%, 10.21%, 8.26%, and 7.35%, respectively. The results of the analysis show that pH and ammonia content of industrial effluent sasirangan affect the death of tilapia fish. This research is hoped that the sasirangan industry does not dispose of its waste directly to the water body but needs to process it first. For further research it can complement the untested parameters such as BOD, COD, and TSS that affect fish survival.
