Authors: Lopes Quiti dos Anjos , neto Ernesto de Paula Guedes , Gross Luiza Azevedo , Pedrini José Luiz , Savaris Ricardo Francalacci
Published: November 2019

Background: The search for new markers for breast cancer (BC) has been sought in order to better understand this type of cancer. The Heart and Neural Crest Derivatives Expressed Transcript 2 (HAND2) has been related to endometrial cancer but there are scant data related to BC. The aim of this study is to compare the immunohistochemical expression of HßAND2 in normal breast tissue vs. BC and to correlate with the estrogen receptor (ERα).
Patients and Methods: In this case-control study, 19 formalin–fixed, paraffin-embedded tissues were obtained from pathological archives. Benign (n=9; control) and cancer (n=10) breast tissue were analyzed with immunohistochemistry for HAND2 (Ab60037), at dilution 1:50 at pH 9 and ERα (SP1). ImageJ software with "color deconvolution" was used for analysis of the expression of these proteins. The sample size was calculated (power=95%, α error= 1%) to identify an increase from mean 15 DAB units (control) to 40 DAB units in cancer.
Results: HAND2 expression (mean ± SD) was 15.5 ± 6.1 (cancer) versus 44.8 ± 21.1 (control) (P=0.002, Student t-test). Its expression was mainly present in the cytosol of the cells. No correlation was observed between ERα and HAND2 (Pearson r = -0.28 (95%CI=-0.6 to 0.22; P=0.2).
Conclusions: The protein expression of HAND2, using Ab60037 antibody, is reduced in breast cancer, compared with normal breast tissue. The expression of HAND2 is not correlated with ERα expression.

Published: December 2019

Purpose: Tumor regression scores are used to evaluate local response to preoperative treatment. Complete pathological response (tumor regression score=0) is associated with excellent prognosis. In this study we evaluated the prevalence and impact of poor-to-no pathological response to neoadjuvant treatment (tumor regression score=3), based on a recently revised grading system on long term oncologic outcomes among rectal cancer patients.
Methods: This retrospective study included rectal cancer patients who received. neoadjuvant chemoradiotherapy and surgical resection at our medical center. Pathological specimens were ren evaluated and graded (grades 0-3) based on the revised tumor regression scores. Disease free survival and cancer specific survival rates were documented and matched with the patients’ tumor regression scores.
Results: Initially 78 patients were included. 6 patients were later excluded from the long-term follow up since they developed disease progression during neoadjuvant treatment. Among the other 72 patients, 38 (52.8%) were classified as tumor regression score=3 (no response) and 34 (47.2%) tumor regression score=0-2 (any level of response). Conversion from laparoscopy to open surgery was higher in the tumor regression score=3 group (21% vs. 2.9%, p=0.02). Follow-up ranged from 5 months to 12 years. Nine (12.5%) patients experienced disease recurrence, 8 with tumor regression score=3. Most recurrences were metastases to liver and lungs. Disease free survival was lower in tumor regression score=3 patients as compared to tumor regression score=0-2.
Conclusions: Non-responders to neoadjuvant therapy are at higher risk for disease recurrence, conversion to open surgery and disease-related mortality. Systemic recurrence of tumor regression score=3 tumors suggests an aggressive biology of these tumors. Further studies are needed to characterize tumors that are less likely to respond to radiotherapy and to personalize preoperative treatment decisions.

Authors: Al-Nass Zainab Jaffar , ZeidanAli Zeidan Abdu , Wahabi Hayfaa Abdelmageed Ahmed
Published: November 2019

Background: Childhood obesity is a major public health challenge of the 21st century. Obese children have double the risk of being obese adults than children who are of normal weight. Obese children bhave increased risks of developing hypertension, dyslipidemia, and other cardio-metabolic morbidities.
Objectives: to investigate the effect of the children food knowledge and preferences on their BMI and the effects of mothers’ nutritional knowledge on their children’s BMI.
Methods: A school-based case-control study design was carried out in the Eastern Region of Saudi Arabia. Data collection was carried out from November 2017 to February 2018. A multistage stratified cluster random sampling technique was used. Four clusters (schools) were selected based on size and equal numbers of participants were included from each cluster. From each of grade 4th, 5th, and 6th, one class was selected randomly. The weight and height of each girl were recorded, BMI calculated, and the students were divided into obese/ overweight group and the normal weight group from which cases and control randomly selected thereafter. Out of total 442 students measured BMI, 348 were included in the study, 116 cases and 232 controls.
Data were collected by face to face interview with the girl, and a self-administrated questionnaire was sent to the same student's mother. Determinants of girls' obesity were calculated using regression analysis. Results were presented as adjusted Odds Ratio (aOR) and 95% confidence intervals (CI).
Result: After controlling for the confounding variables, more healthy food preferences in children and higher mother's knowledge were associated with 77% and 51% reduced odds of overweight-obesity (aOR = 0.23 95% CI 0.09–0.64 and aOR = 0.49 95% CI 0.33–0.71).
Conclusion: Healthy food preferences among girls and adequate nutritional knowledge among their mothers were significantly associated with decreased obesity in girls.
Limitations: The main limitations were its inability to assess causation and the potential for recall bias, especially in the questions related to behaviors; namely, physical activity and diet recall.

Authors: Hashimi Batol Shiwa , Boudjella Aissa , Saboor Wagma
Published: November 2019

The purpose of this investigation is to examine the variation of temperature in Japan over the past 114 years. The historical dataset of the monthly average temperature from 1901 to 2015 were analyzed. The relationship between temperature and time during the four time intervals, i.e (1901 -1930), (1931-1960), (1961-1990) and (1991-2015) is described using a new analytical model based on the last â€“square method of estimation. We accurately fit a polynomial regression trend of degree 4 to the time series to describe the temperature variation. The results show the average difference of temperature between 2015 and 1901 increases about 0.97 Â°C. The average monthly difference between the maximum and minimum temperature was approximately 2.11 Â°C. This approach of modeling temperature using regression form significantly simplifies the data analysis. The information from data, namely the variation of the temperature, maybe be obtained from the extracted parameters such as slope, y-intercept, and the coefficients of polynomial function that are a function of time. More importantly, the parameters that describe the time variation temperature trends over 115 years obtained with a high R-squared do not vary significantly. This is in agreement with the Earthâ€™s average temperature that has climbed to more 1 oC.

Treatment of late stages of the tumor process requires the implementation of increasingly high-tech and complex interventions, aimed at improving the overall and disease-free survival, improving the quality of life of patients. HIPEC technique is a point of growth at which progress in oncology and all medical science can be demonstrated. Among the specialists involved in the implementation of this type of specialized care, there is still no consensus on what traits the malignant process of the peritoneum should be able to use this technique. Intraperitoneal hyperthermic perfusion (HIPEC) is gaining popularity as a method of palliative treatment of patients with common tumors of the abdominal cavity. Using the popular medical virtual search engine PubMed identified 2140 cited publications on the search query "hipec, peritoneal" and 752 cited publications "hipec, peritoneal, CRS", finally the phrase "hipec, cancer, randomized trial" with the clarifying characteristic "Clinical Trial" (excludes review articles) – 30 scientific publications, 10 of them in the last 5 years. All this demonstrates the growing interest to HIPEC around the world. The technique is used mainly for ovarian cancer, mesothelioma, pseudomyxoma of the peritoneum, colorectal cancer, and gastric cancer. It is possible as a combination of surgically performed PE and HIPEC, and HIPEC in mono-mode, in the absence of macroscopically detected carcinoma of the abdominal cavity, but positive washings from the peritoneum in verified cancer. It is performed both during the cytoreductive operation and as the second stage as a component of the Second look procedure, as well as in the adjuvant mode in the absence of carcinomatosis, but of high potential danger of peritoneal dissemination (for example, if the tumor has infiltrated the entire wall of the organ). HIPEC has never become a standard treatment, and multicenter randomized trials are regularly conducted on this topic.

Spreading of chemical substance after its accidental spillage onto the soil surface under unsaturated conditions and variable porosity
Authors: Kozhushko Olena , Martyniuk Petro
Published: November 2019

In this paper we study a mathematical model of soil moisture transport with variable porosity. The problem is set for the case of highly concentrated solute spilled onto soil surface. We investigate the way solute transfer, adsorption of contaminant by soil particles and variable porosity influence infiltration of solute into the soil profile. For that purpose, two models are used: a classical one and the one with consideration of mentioned factors. By comparing the results of both models, we established that high concentration of solute causes moisture transport to transpire more slowly, and the pollutant to remain on the soil surface for longer time. Numerical results indicate that porosity can vary considerably under the conditions of intensive contamination with salts.

The article proposes to use of a combination of the criterion method and Markov processes to evaluate the quality of functioning of renewable energy sources (RES) in the form of integrated readiness characteristic of the electricity network with RES or a local electrical system (LES). This is possible throughthe analysis of the problems of ensuring the quality of electricity supply in the conditions of intensive development of RES and defined by the qualimetric characteristics of the electricity networks, which are important for the provision of quality electricity. This contribute the development of generalizedsolutions and network development strategies, especially when it comes to building RES. The components of the integral index are determined as the probability of matching the actual regime to the "ideal". The "ideal" mode is determined on the basis of the principle of least action and corresponds to the circuit diagram of the network formed by the r-scheme. The basis thus determined in this way reduces the subjectivity of both evaluations and decisions taken on the basis of it.

Hasil dari penelitian ini adalah berupa sumbangan positivime Auguste Comte terhadap pengembangan ilmu dakwah dari aspek ontologi, epistomologi, dan aksiologi.    Abstract:Auguste Comte (1798-1857) was a French philosopher who initiated the flow of positivism. This term began to be used by Comte in his work "Cours de Philosophic Positive". Aside from being a philosopher, Auguste Comte also received the title as "Father of Modern Sociology". Positivism is a school of thought that emphasizes the validity of data empirically-verification, so that sensory knowledge is used as the only norm for scientific activity. Despite many criticisms, of course, as a result of philosophy, Auguste Comte's positivism was very important in the development of other sciences such as da'wah. The results of this study are in the form of the contribution of Auguste Comte's positivime to the development of da'wah from the aspects of ontology, epistomology, and axiology.

Commitment and the Second-Person Standpoint
Authors: Schaab Janis
Published: December 2019

On Chang's voluntarist account of commitments, when we commit to φ, we employ the 'normative powers' of our will to give ourselves a reason to φ that we would otherwise not have had. I argue that Chang's account, by itself, does not have sufficient conceptual resources to
reconcile the normative significance of commitments with their alleged fundamentally volitional character. I suggest an alternative, second-personal account of commitment, which avoids this problem. On this account, the volitional act involved in committing is one of holding ourselves accountable,
thus putting us under to a pro tanto obligation to ourselves. The second-personal account implies that there is an interesting link between commitment and morality.
