Published: February 2021

BACKGROUND: Post-therapeutic tissue is bradytrophic and thus has low perfusion values in PCT. In contrast, malignant tissue is expected to show higher perfusion values as cancer growth partially depends on angiogenesis. OBJECTIVES: This prospective study investigates perfusion computed tomography (PCT) for the post-therapeutic detection of cancer in the head and neck region. METHODS: 85 patients underwent PCT for 1) initial work-up of head and neck cancer (HNC; n=22) or 2) for follow-up (n=63). Regions of interest (ROIs) were placed in confirmed tumour, a corresponding location of benign tissue, and reference tissue. Perfusion was calculated using a single input maximum slope algorithm. Statistical analysis was performed with the Mann-Whitney U-test. RESULTS: PCT allowed significant differentiation of malignant tissue from post-therapeutic tissue after treatment for HNC (p=0.018). Significance was even greater after normalization of perfusion values (p=0.007). PCT allowed highly significant differentiation of HNC from reference tissue (p<0.001). CONCLUSIONS: PCT provides significantly distinct perfusion values for malignant and benign as well as post-therapeutically altered tissue in the head and neck area, thus allowing differentiation of cancer from healthy tissue. Our results show that PCT in conjunction with a standard algorithm is a potentially powerful HNC diagnostic tool.

OBJECTIVE: To assess the impact and procedural input of intraoperative ultrasound (IOUS) with contrast-enhanced ultrasound (CEUS) and ultrasound elastography on surgical decision making during the procedure and consequently the outcome after hepato-pancreatico-biliary (HPB) surgery. MATERIALS AND METHODS: Data of 50 consecutive patients, who underwent HPB surgery from 04/2018 to 07/2018 were prospectively collected for this study. During surgery, IOUS with a high-resolution ultrasound device using CEUS after bolus injection of 2.4–5 ml dulphur hexafluoride microbubbles using a 6–9 MHz probe and a share wave and strain elastography was performed by an experienced examiner. Process and time analysis were carried out using mobile phone timer. RESULTS: The IOUS with CEUS and elastography correctly identified 42 malignant tumors and 4 benign lesions. In 3 cases, the examination provided false positive result (identifying 3 benign lesions as malignant) and in 1 case a malignant lesion was incorrectly assessed as benign (sensitivity 97,7%, specificity 57,1%, PPV 93,3% and NPV 80%). The specific question by the surgeon could be answered successfully in 98% of the cases. In 76% of the cases, there was a modification (42%) or a fundamental change (34%) of the planned surgical approach due to the information provided by the IOUS. Within the last group, the IOUS had a major impact on therapy outcome. In 7 patients an additional tumor resection was required, in 5 patients the tumor was assessed as inoperable, and in total in 5 patients an intraoperative RFA (4/5) or postoperative RITA (1/5) was required. Regarding procedural input, there was only a slight, but significant difference between the transport and set-up times before the intraoperative use (mean: 14 min 22 s) and the return transport (mean 13 min 6 s), (p = 0,038). The average examination time was 14 minutes, which makes only one third of the overall time demand. CONCLUSION: Combination of IOUS with CEUS and elastography in oncological HPB surgery provides valuable information that affects surgical decision-making. The procedural input of about 45 minutes seems to be a good investment considering the improvement of the surgical procedure and a significant modification of the therapy approach in the majority of the cases.
A time series approach to player churn and conversion in videogames
Authors: Fernández del Río Ana , Guitart Anna , Periánẽz África
Published: February 2021

Players of a free-to-play game are divided into three main groups: non-paying active users, paying active users and inactive users. A State Space time series approach is then used to model the daily conversion rates between the different groups, i.e., the probability of transitioning from one group to another. This allows, not only for predictions on how these rates are to evolve, but also for a deeper understanding of the impact that in-game planning and calendar effects have. It is also used in this work for the detection of marketing and promotion campaigns about which no information is available. In particular, two different State Space formulations are considered and compared: an Autoregressive Integrated Moving Average process and an Unobserved Components approach, in both cases with a linear regression to explanatory variables. Both yield very close estimations for covariate parameters, producing forecasts with similar performances for most transition rates. While the Unobserved Components approach is more robust and needs less human intervention in regards to model definition, it produces significantly worse forecasts for non-paying user abandonment probability. More critically, it also fails to detect a plausible marketing and promotion campaign scenario.
Detection of effort maximality in adults performing isokinetic wrist flexion and extension
Authors: Torra Mercè , Pujol Eduard , Maiques Anna , Quintana Salvador , Garreta Roser , Chaler Joaquim
Published: February 2021

BACKGROUND:

The difference between isokinetic eccentric to concentric strength ratios at high and low velocities (DEC) is a powerful tool for identifying submaximal effort in other muscle groups but its efficiency in terms of the wrist extensors (WE) and flexors (WF) isokinetic effort has hitherto not been studied.

OBJECTIVE:

The objective of the present study is to examine the usefulness of the DEC for identifying suboptimal wrist extensor and flexor isokinetic efforts.

METHODS:

Twenty healthy male volunteers aged 20–40 years (28.5 [Formula: see text] 3.2) were recruited. Participants were instructed to exert maximal and feigned efforts, using a range of motion of 20[Formula: see text] in concentric (C) and eccentric (E) WE and WF modes at two velocities: 10 and 40[Formula: see text]/s. E/C ratios (E/CR) where then calculated and finally DEC by subtracting low velocity E/CR from high velocity ones.

RESULTS:

Feigned maximal effort DEC values were significantly higher than their maximal effort counterparts, both for WF and WE. For both actions, a DEC cutoff level to detect submaximal effort could be defined. The sensitivity of the DEC was 71.43% and 62.5% for WE ad WF respectively. The specificity was 100% in both cases.

CONCLUSION:

The DEC may be a valuable parameter for detecting feigned maximal WF and WE isokinetic effort in healthy adults.

INTRODUCTION: Cycling has been the subject of numerous studies. Among these, measuring muscular performance during cycling has attracted much interest. OBJECTIVE: To investigate the relationship between Wattbike® and isokinetic findings in a group of cyclists. METHODS: Thirty-seven male cyclists performed a 30-s anaerobic power test on a Wattbike® and then were tested concentrically for knee extensor and flexor strength using isokinetic dynamometry. RESULTS: There was a positive fair-to-moderate correlation between the peak moment, peak power, and total work derived from the Wattbike® and the respective parameters evaluated isokinetically. CONCLUSION: While the findings exclude interchangeability of the two methods, the fact that total work is the most closely associated parameter among the measurements highlights its importance as an outcome measure in muscle performance in cyclists.

Published: February 2021

The objective of the paper is to present a multiple criteria hierarchical process (MCHP) approach for portfolio selection in a stock exchange. One of the problems that investors usually face is which stock should be included in the portfolio. This paper helps investors answer that question, and the paper presents an MCHP approach using different criteria based on financial ratios that the decision maker (in this case, the investor) will give different weights to make a portfolio based on her preferences; different importance is given to each criterion. An example using the Mexican Stock Exchange is presented.

Regardless of the sizable number of terrorist attacks in the last decade in Jordan, Jordanians’ fear of the terrorists or risk of dying in a terrorist attack in Jordan is almost non-existent. What drives the young educated student to sympathize and support terrorist groups like ISIS? Sympathy and support for terrorist groups like ISIS among youths in Jordan can be understood by tracing its roots of the micro (personal factors), meso (institutional factors), and macro-level (social, cultural factors). Youths’ sympathy and support for ISIS are based on religious beliefs, social taboos, kinship, and social ties. The current study aims at examining radical, conservative, and extremist thoughts, fear about, and behavioral and material support for ISIS among college students in Jordan. Findings showed that, on average, 59% of students expressed radical thoughts, concentrated on areas of social and religiously conservative and extremist beliefs. Moreover, results showed that 66% of students carried extreme ideas, with 90.7% accepting the use of violence. More than half (61%) of the sample expressed conservative thoughts ranged from stoning adultery cases (82.4%) to segregation of women in the workplace (59.4.%). Findings showed less than half of the sample, 43.4% feared that they might become victims of ISIS one day, and 69.4% of students worried about the emergence of radical groups in Jordan. Also, findings showed that about 10% of students expressed behavioral or/and material support for ISIS ranging from money donation (11.7%) to providing personal and operational assistance (8%). Students’ overall average justification for ISIS’s support was 14%, and 15.6% of students justified their behavioral and material support for ISIS due to foreign assistance for Muslim authoritarian regimes. The lowest justification was for seeing ISIS as a defender of Islam. Finally, there was a significant relationship between radical thoughts and each of the support justifications (r = .254), strain (0.32), fear (0.46), religiosity (0.78), and ISIS support (r = .297). Additionally, there is a significant relationship between ISIS’s support and ISIS’s support justification (r = .72). Radical thoughts, violent extremism beliefs, conservative beliefs, stress, victimization, and justification explained 56% of the variance on behavioral and material support for ISIS and had an overall significant effect on behavioral and material support for ISIS (F = 85.936, α = .000).
Managing Fear in a Post-Factual Era
Authors: Forst Brian
Published: February 2021

Fear is dangerous because of its tendency to cause our instincts to overrule our ability to think; get us to behave against our self-interests; make us more easily exploited by politicians, terrorists, and others with harmful intentions; create enemies; and feed on itself in a vicious downward spiral. The problem is worsened by irresponsible media, politicians who exploit fear by distorting facts about threats to security, social networks that spread hatred and misinformation on the Internet, and cyberattacks. This paper describes these forces and argues that the vicious cycle of fear and the exploitation of fear can be broken by electing responsible leaders, using fear management programs at the national and state levels, applying lessons learned from community policing programs to reduce fear at the local level, and by instituting stronger sanctions against Internet abuse, including defenses against cyberattacks.

The prevalence of iron-deficiency anemia (IDA) is steadily increasing. IDA is more common in women of reproductive age, pregnant women, and adolescent girls thus accounting for the importance of this issue in obstetrics and gynecology. Abnormal uterine bleeding (AUB) is one of the most common causes of IDA both in the puberty and reproductive period which requires hemostasis as well as addressing iron deficiency. A high rate of IDA was also reported in women with pelvic inflammatory diseases; this should considered when managing this large group of gynecological patients. The treatment for anemia or latent iron deficiency is performed for a long time, therefore, the selection of a medication is particularly important. Peroral Tardyferon® containing 80 mg of iron meets all modern-day requirements for anti-anemic drugs and is recommended for anemia resulting from AUB both in women of reproductive age and adolescent girls. Case studies illustrate high efficacy and good tolerability of this medication. KEYWORDS: iron-deficiency anemia, pregnancy, abnormal uterine bleeding in puberty, heavy menstrual bleeding, genital inflammation, high efficacy, compliance.

Tolosa-Hunt syndrome (THS) is a rare disease manifested with one or more cranial nerve disorders and orbital pain. In children, THS is diagnosed very rarely due to the lack of vigilance among physicians. Careful examination including MRI or helical CT help diagnose this disease. This paper discusses case history of THS in a child in the first ten years of life who has previously experienced similar episodes of ptosis and right-sided orbital pain; however, the cause of these symptoms has remained elusive. Disease anamnesis, clinical signs, neurological status, and additional diagnostic data are described in detail. Clinical course of THS with its relapses and remissions, rapid symptom regress after corticosteroid pulse therapy, and no specific granulomatous inflammation of the lateral wall of the cavernous sinus as demonstrated by MRI suggest idiopathic THS. The importance of in-depth neurological and general examination of patients with clinical signs of THS due to a variety of the causes of this syndrome is highlighted.

Recent data suggest that the technical staff’s appraisals of the condition and development of economic activity, inflation and the labor market have been in line with current trends, marked by a decline in demand and the persistence of ample excess productive capacity. A significant projected fall in output materialized in the second quarter, contributing to a decline in inflation below the 3% target and reflected in a significant deterioration of the labor market. A slow recovery in output and employment is expected to continue for the remainder of 2020 and into next year, alongside growing inflation that should remain below the target. The Colombian economy is likely to undergo a significant recession in 2020 (GDP contraction of 7.6%), though this may be less severe than projected in the previous report (-8.5%). Output is expected to have begun a slow recovery in the second half of this year, though it is not projected to return to pre-pandemic levels in 2021 amid significant global uncertainty. The output decline in the first half of 2020 was less severe than anticipated, thanks to an upward revision in first-quarter GDP and a smaller contraction in the second quarter (-15.5%) than had been projected (-16.5%). Available economic indicators suggest an annual decline in GDP in the third quarter of around 9%. No significant acceleration of COVID-19 cases that would imply a tightening of social distancing measures is presumed for the remainder of this year or in 2021. In that context, a gradual opening of the economy would be expected to continue, with supply in sectors that have been most affected by the pandemic recovering slowly as restrictions on economic activity continue to be relaxed. On the spending side, an improvement in consumer confidence, suppressed demand for goods and services, low interest rates, and higher expected levels of foreign demand should contribute to a recovery in output. A low base of comparison would also help explain the expected increase in GDP in 2021. Based on the conditions laid out above, economic growth in 2020 is expected to be between -9% and -6.5%, with a central value of -7.6%. Growth in 2021 is projected to be between 3% and 7%, with a central value of 4.6% (Graph 1.1). Upward revisions compared to the July report take into account a lower-than-expected fall in first-semester growth and a somewhat faster recovery in the third quarter in some sectors. The forecast intervals for 2020 and 2021 growth tightened somewhat but continue to reflect a high degree of uncertainty over theevolution of the pandemic, the easures required to deal with it, and their effects on global and domestic economic activity.
Pemanfaatan Getah Pinus dan Perannya Terhadap Penghidupan Masyarakat di Provinsi Sulawesi Selatan
Authors: Tajuddin Tajuddin
Published: February 2021

Pine forest in South Sulawesi is one of the evidence of successful reforestation and has been utilized by the community in the form of tapping pine resin. This article explains the permits types of the utilization/collection of pine resin by the community, the role of pine resin in community livelihoods, and various problems in the utilization of pine resin by the community in South Sulawesi. Qualitative/quantitative descriptive analysis is used to analyze primary data obtained through interviews and secondary data analysis obtained from relevant agencies. We found that the utilization/collection of pine resin in South Sulawesi by the community used four schemes or permits types, namely: Business License for Non-Timber Forest Product Utilization, Licence for Collection of Non-Timber Forest Products, Social Forestry Schemes Permits, and Cooperation of Forest Utilization. Furthermore, for the community livelihoods, utilization/collection of pine resin has provided extra incomes and employment for local communities and workers from outside. However, labor limitations, fluctuations in the price of pine resin, relying on the community on business partners, and tapping techniques that contradict the principle of forest sustainability is still becoming the problems in the utilization/collection of pine resin in South Sulawesi.

The existence of the LPHD is considered important, because it can improve the standard of living of the community around the forest area as well as be able to maintain the stability of the forest ecosystem, one of which is the LPHD Muara Danau, but its management is still considered not optimal in developing agroforestry businesses. This study aims to analyze the performance of the LPHD Muara Danau in village forest management. The research methodology are interviews, observation, and documentation studies. The data obtained were analyzed descriptively. Results showed that the performance of the Muara Danau LPHD was categorized as quite good, this was seen from three aspects, namely institutional, area and business management. The institutional management aspect is measured based on the participation of the management and LPHD members in participating in the activities as many as >75% of the members are present in the activity (91%) and the type of binding group rules in the form of (AD/ART) and unwritten rules (84%) and area management is measured based on types of forest resource conservation activities carried out were 52 people (95%) and the impact that was felt by 2-4 impacts on the environment from Village Forest management was 48 people (87%). However, business management has not yet achieved optimal results, measured based on the absence of local institutions (cooperatives) that carry out marketing of forest products. LPHD agroforestry business development needs to be increased in order to maximize the marketing of forest products.

Authors: Nirma Amit Kumar , Kumar Aditya , Kumar Satish
Published: February 2021

Aim: to analyse the thyroid profile, hs-CRP and lipid profile in newly detected hypothyroid adults in comparison to controls and also to compare the above parameters in subclinical and clinical hypothyroid cases.

Material and methods: The study was a cross sectional study which was carried in Nalanda Medical College and Hospital, Patna, Bihar, India from October 2019 to march 2020. Total 240 patients were divided into 2 groups. Group-1 for newly detected hypothyroid adults and Group 2 as Controls. Blood samples were collected with full aseptic precautions after obtaining informed consent. Clot activator that contains vacuum evacuated tubes for analysis of serum TSH, FT3, FT4, TC, HDL-c, LDL-c, TG, hs-CRP. Then after collection, serum samples were stored at -200 until analyzed. Anthropometric measurements for BMI, height (cm) and body weight (kg) were measured.

Results: The mean age of cases and controls in our study was found to be 36.12±12.21years and 35.87±11.06years respectively (p = 0.81). BMI values in the study were higher in cases (27.24 ± 4.65kg/m2) compared to controls (25.17 ± 4.37kg/m2) and was statistically significant (P = 0.03). In the study, the mean TSH levels (15.27 ± 9.2µIU/ml) of cases were high compared to controls (3.1 ± 0.88µIU/ml) and were statistically significant (p<0.001). The mean serum hs-CRP levels in both the study groups was within the reference range, but it was high and statistically significant in cases than in control (p = 0.004). The total cholesterol level in cases (182.29 ± 39.75mg/dl) and control (184.27±28.37mg/dl) were within the reference range and there was no statistical significance (p = 0.82). Further it was found that HDL-c in cases (45.89±9.47mg/dl) and control (52.87±6.7mg/dl) were found to be lower in cases compared to controls and the difference was statistically significant (p < 0.001). The mean LDLc value in cases (145.14±34.12mg/dl) and control (132.05±32.14mg/dl) was high in cases and the difference was statistically significant (p= 0.01). The triglyceride levels of cases (159.26±49.87mg/dl) were significantly higher than that of control (146.23±29.27mg/dl) and was statistically significant (p=0.03). hs -CRP levels were in within reference range for 92 (76.67%) of cases and 109(90.83%)controls whereas above the normal range was seen in 28 (23.33%) cases and only 11(9.17%) controls. Out of 120, 64.17% (n=77) were subclinical hypothyroid (SCH) and 35.83% (n=43) were clinical hypothyroid (CH) cases. There was a significant increase in serum TSH in CH (24.11 ± 9.1µIU/ml) as compared to SCH (10.2 ± 2.2 µIU/ml). The difference was statistically significant (p<0.001).

Conclusion: we concluded that the hypertriglyceridemia and at risk hs-CRP levels though seen in hypothyroid cases were more prominent in CH cases than SCH. Dyslipidemia and inflammatory markers were found to be increased in the cases that helped in prediction and evaluation of patients at risk of cardiovascular disease.

The use of parametric modeling and calculation tools to assess the insolation characteristics of architectural objects allows us to make a qualitative assessment of the degree of heating of the building exterior, which therefore accelerates the stage of the preliminary design of sun protection elements and clearly demonstrates their effectiveness. Rhino and grasshopper are convenient tools that can be used for this purpose. Using grasshopper plug-ins, we have a visually clear diagram that demonstrates the stability of the use of various additional facade solutions. Optimization and improvement of the exterior help to avoid energy loss, which contributes to savings and improves environmental friendliness, this allows architects to follow global trends in energy efficiency sustainability.
Estudo sobre o Respeito ao Princípio da Autonomia em Crianças e/ou Adolescentes sob Tratamento Oncológico Experimental, através do Processo de Obtenção do Consentimento Livre e Esclarecido
Authors: Teixeira Vânia Maria Fernandes , Braz Marlene
Published: February 2021

O presente estudo se propôs a analisar o respeito ao princípio da autonomia em crianças e/ou adolescentes, sob tratamento oncológico experimental, através do processo de obtenção do Termo de Consentimento Livre e Esclarecido (TCLE), para fins de pesquisa, por meio de um estudo de casos, de caráter exploratório, de cunho qualitativo. Os dados foram obtidos através de entrevistas temáticas e interpretados pela análise indiciária. Foram entrevistados: três crianças, um adolescente, quatro pesquisadores e quatro mães. Os resultados mostraram que a autonomia, mesmo relativa, da criança e/ou adolescente, não é levada em consideração, o que se traduz pela não obtenção do TCLE, uma vez que os pais e pesquisadores acreditam que essas crianças e/ou adolescentes não são capazes de entender os riscos e benefícios da pesquisa. Neste sentido, a decisão dos pais, em permitir a participação da criança e/ou adolescente nesse tratamento experimental, foi baseada na esperança de cura para o filho e, por isso, são eles quem assinam o TCLE. Tanto pesquisadores quanto os responsáveis não consultaram a criança e/ou adolescente sobre o tratamento proposto. As decisões de saúde na infância e adolescência dependem dos adultos; contudo, esse grupo foi considerado competente e capaz de decidir situações rotineiras em família. Por outro lado, as crianças e/ou adolescentes sabiam de suas condições de saúde e identificaram a possibilidade da pesquisa/tratamento não lhes trazer benefícios, haja vista a convivência com a realidade da morte de outras crianças, na enfermaria, que sofreram o mesmo tratamento.

O pamidronato dissódico, bifosfonato utilizado no tratamento de diversas condições, como hipercalcemia oncogênica, osteoporose e Doença de Paget, pode alterar a biodistribuição do MDP-99m Tc na cintilografia óssea. Relata-se um caso de importante redução da fixação óssea e aumento da captação em partes moles e pulmões em paciente neoplásico com metástases ósseas e hipercalcemia oncogênica tratado recentemente com pamidronato intravenoso. O provável mecanismo responsável pela alteração descrita seria a competição do MDP pelo mesmo sítio de ligação do pamidronato nos cristais de hidroxiapatita. Já o acúmulo do radiotraçador nos pulmões pode ser atribuído à provável formação de microcalcificações decorrente da hipercalcemia apresentada pelo paciente. Vale ressaltar, portanto, a importância do conhecimento dessas possíveis alterações pelos especialistas em medicina nuclear, a fim de se evitar erros diagnósticos.

The number of verses in the Qur'an that is not small will be difficult and time consuming if done manually. Building a search system in the Qur'anic verse using the Indonesian Arabic-Latin equivalent will be very helpful for the Muslim community in Indonesia, especially for those who are not familiar with Arabic writing. In this study, a verse search system will be built on the Al-Qur'an based on phonetic similarity, more details about the handling of the verses in the Al-Qur'an. The system was built using the Jaro-Winkler algorithm to calculate the value of similarity and using the N-Grams algorithm for ranking documents. The same study has been done before with the name Lafzi +, with MAP 90% and 93% recall. In previous studies cases such as nun wiqoyah at the end of the verse could not be handled, so the system could not handle the search for the entire Qur'an. In addition, in the previous system the application of the Jaro-Winkler method to calculate the value of similarity has also not been fully implemented. So to complete the previous research, in this study added rules other than pre-existing rules so that they can handle nun wiqoyah at the end of the verse. By applying the Jaro-Winkler method to calculate the value of similarity and N-Grams for ranking documents and adding nun wiqoyah rules, this system generates 94% MAP and 92% recall. The results of this study indicate an increase in MAP, this shows that this system can improve the accuracy of systems that have been built before.

Na postura “ganha-ganha”, todos podem obter vantagens e saírem ganhando já que o acordo é mais provável. Porém, há obstáculos na negociação, quando há prejuízo, podendo ocorrer o rompimento na relação. Além disso, uma má negociação produz consequências futuras, porque há muitas variáveis que tornam imprevisível o resultado. Assim, este artigo apresenta a técnica “ganha-ganha” a partir de seus modos e estratégias, bem como as maneiras que devem ser evitadas pelo negociador. A negociação “ganha-ganha”, atualmente, tem a maior interdependência entre pessoas, empresas e instituições na busca de parcerias contíguas para se obter qualidade e produtividade, o que pode tornar a negociação mais eficaz. Este artigo tem como objetivo apresentar as experiências de negociação “ganha-ganha” realizadas pelas organizações no mercado brasileiro. A metodologia optada para o desenvolvimento desta pesquisa baseou-se na análise qualitativa, realizada através de levantamento bibliográfico. Foram pesquisados autores das áreas de negociação para que fosse possível associar a temática a ser estudada. Os principais pontos avaliados foram a evolução dos conceitos que abarcam a negociação e seu aprimoramento, que visam gerar um ambiente saudável para contenda e solução de conflitos.
