Objectives
Breast cancer (BC) is a major global health issue as it is the most common malignancy in women. Despite, the role of neoadjuvant chemotherapy (NAC) in early BC has been established, there is a non-small proportion of patients who might develop chemoresistance. Several studies have investigated the relationship between microRNA-210 (miRNA-210) and neoadjuvant chemoresistance in BC with controversial results. Thus, this study aimed to evaluate the role of miRNA-210 as a predictor for chemoresistance in BC receiving NAC.

Material and Methods
The study enrolled 15 chemo-sensitive and 15 chemo-resistant patients with BC receiving NAC. In addition, 10 newly-diagnosed BC patients before treatment and 10 healthy women were recruited as controls. Serum samples from all patients and controls were withdrawn and measurements of miRNA-210 levels using quantitative real-time reverse transcriptase-polymerase chain reaction (qRT-PCR) were done and compared.

Results
The median value of miRNA-210 level was 1.53, 0.27, 0.52, and 1.35 in chemo-sensitive, chemo-resistant, newly-diagnosed, and control groups, respectively. A statistically significant difference (Chi square = 9.801, p = 0.020, df = 3) was found in the mean serum miRNA-210 among the four different groups. Using logistic regression model, low serum miRNA-210 expression level was found to be a predictive factor of chemo-resistance with p = 0.038 (OR of 0.103, 95% CI = 0.012 –0.886). Using the receiver operating characteristic curve, it was found that the area under the curve (AUC) was 0.747 (95% CI = 0.550 –0.943).

Conclusion
Serum miRNA-210 could be an effective predictive biomarker for chemoresistance in BC patients receiving NAC.
A survey regarding awareness of ‘plagiarism while writing articles’ among students and faculty members of Indian colleges/universities
Authors: Ambwani Meenakshi , Nayak Chaturbhuja 
Published: August 2023

Objectives:
Originality concerning scientific and research publications is of vital importance in this day and age and must be protected. With literary piracy reaching celestial heights in recent times, ethics must be maintained so that research integrity prevails. Plagiarism ranges from copying a few words to entire paragraphs and even ideas. The contribution(s) of the original author are not mentioned, not even using in-text citations. Plagiarism occurs largely due to the writer’s ignorance, but may be deliberate on occasion. The aim of the study was to understand the level of awareness among students and faculty members of Indian colleges/universities about plagiarism and its related aspects while writing and publishing articles.

Materials and Methods:
A virtual cross-sectional survey was conducted on students and faculty members using Google Forms. A 20-item self-administered questionnaire was framed by the authors after an extensive review of the literature and circulated through various WhatsApp groups to extract information from the participants about causes of plagiarism, paraphrasing, money-oriented publication agencies, plagiarism checker software and preventive measures.

Results:
Of 63 total respondents, 93.7% of participants were just aware of the term plagiarism in relation to writing papers and research articles, although 54% admitted that they had never written an article.

Conclusion:
The overall analysis highlighted that around 93% of responders had preliminary knowledge about plagiarism, but were still unaware of the seriousness of the problem and its grave consequences. Extensive campaigning and workshops need to be conducted to guide writers about the rules of publication ethics to prevent such malpractice.

Published: August 2023

Objectives:
Hyperlactatemia is associated with increased risk of mortality. Point-of-care (POC) lactate levels have been used worldwide in the emergency department (ED) and critical care units for risk stratification. The aim of this study was to determine whether POC lactate levels are predictive of outcomes in our low-resource setting.

Materials and Methods:
This was a non-interventional prospective cohort study carried out at the ED Critical Care wards in Kenyatta National Hospital between June 12, 2021, and July 25, 2021. The study included consecutively consenting adults above 18 years at the ED who were critically ill as indicated by a Modified Early Warning Score of equal to or above 5. Lactate was measured using a handheld Statstrip lactate meter. Patients were followed up for 7 days, and outcomes were documented.

Results:
Two hundred and eighty-one patients were enrolled in the study. The mean lactate level was 4.0 mmoL/L with a median interquartile range of 3.0. Hyperlactatemia was evident in 161 (57%) using a cutoff of 2.5 mmoL/L. The all-cause mortality rate was 33.8%. Type A hyperlactatemia was the most common at 84.3% and 17.7% in Type B. Type A hyperlactatemia mortality rate was 37.1% and Type B 15.9% (odds ratio [OR]: 3.1, 95% confidence interval [CI]: 1.3– 7.3, P = 0.006). In the high lactate group, the 7-day mortality rate was 42.2% compared to a mortality rate of 22.5% in the normal lactate group (OR: 2.5, 95% CI: 1.5–4.3, P = 0.001). Hyperlactatemia was associated with an increased need for intensive care unit admission (OR: 2.2, 95% CI: 1.3–3.7, P = 0.002) and organ support mainly mechanical ventilation (OR: 2.6, 95% CI: 1.5–4.4, P = 0.001) and inotropic/vasopressors support (OR: 2.7, 95% CI: 1.2–6.2, P = 0.016).

Conclusion:
POC lactate is an independent predictor of 7-day mortality with a 2-a fold increased risk of mortality and was associated with increased need for organ support.

Purpose: Humans are equipped by God with reason, and with their reason humans can think. If humans think deeply to find the root of a problem, then an entrepreneur is actually philosophizing to find the root of the problem of his business with a solution that is productive and beneficial for everyone involved.

Theoretical framework: This study aims to explain a practical implementation of philosophy in relation to the foundation of thought, business choices and rationality as an entrepreneur who dares to take risks in his entrepreneurial activities in an existentialist manner.

Design/Methodology/Approach: This study uses a descriptive qualitative method through a secondary data analysis approach.

Findings: This research arrives at the conclusion that existentialist entrepreneurs see a creative and innovative work that will make them exist in society.

Research, Practical & Social implications: This is because they tend to develop their potential, expertise, and credibility to become a product or work that is beneficial to humans without expecting excessive rewards. In fact, the reward for them is the essence of a useful life.

Originality/Value: This study is expected to be a reference in the academic realm in the field of entrepreneurship formally. In addition, it is highly recommended to be applied to every individual character who will be an entrepreneur, as well as those who have started. Because, it is never too late to start something in order to get good for personal, family and among God's creations as social beings.

Purpose: The present study aimed to explore factors causing work-family conflicts and family-work conflicts among married female public bank managers in West Java, Indonesia.

Theoretical framework: Variables such as family size, child's age, working hours, and level of social support are found to affect one's experience of work-family and family-work conflicts. These variables have been conceptualized as the antecedents of work-family and family-work conflicts. However, it is important to consider the effect of these variables on working women's psychological stress and wellbeing. This study aimed to identify the antecedents of work-family conflict and family-work conflicts among married working women. Although many studies have investigated issues on work-life balance, there is no study that reports the antecedents of work- family and family-work conflicts.

Design/Methodology/Approach: The participants were 93 married female managers aged between 30 to 50 years old who lived together with their family and were directly involved in their job. The survey was conducted by administering a six-point likert scale questionnaire, ranging from 1 (strongly agree) to 6 (strongly disagree). The obtained data had passed the normality, validity, and reliability test. After that, ANOVA was applied to find out the significance difference in the two data group.

Findings: This study found different levels of work-family conflict among female managers due to number and age of children and manager level, which affect their job quality and motivation.

Research, practical & social implications: The implication of this study is the growing needs of providing a working environment for women, including job satisfaction, communication, family support, and flexible working hours.

Originality/Value: This study fills the gap of knowledge by investigating the dual roles conflict among female public bank managers in West Java Province, Indonesia.
