Abstract

Purpose

The incidence of prostate cancer is increasing from the past few decades. Various studies have tried to determine the survival of patients, but metastatic prostate cancer is still not extensively explored. The survival rate of metastatic prostate cancer is very less compared to the earlier stages. The study aims to investigate the survivability of metastatic prostate cancer based on the age group to which a patient belongs, and the difference between the significance of the attributes for different age groups.

Design/methodology/approach

Data of metastatic prostate cancer patients was collected from a cancer hospital in India. Two predictive models were built for the analysis-one for the complete dataset, and the other for separate age groups. Machine learning was applied to both the models and their accuracies were compared for the analysis. Also, information gain for each model has been evaluated to determine the significant predictors for each age group.

Findings

The ensemble approach gave the best results of 81.4% for the complete dataset, and thus was used for the age-specific models. The results concluded that the age-specific model had the direct average accuracy of 83.74% and weighted average accuracy of 79.9%, with the highest accuracy levels for age less than 60.

Originality/value

The study developed a model that predicts the survival of metastatic prostate cancer based on age. The study will be able to assist the clinicians in determining the best course of treatment for each patient based on ECOG, age and comorbidities.

Abstract

Purpose

Breast cancer is the most increasing female cancer worldwide, including Bangladesh. The purpose of this study was to investigate the association between dietary patterns and knowledge perception of breast cancer risk patients in Bangladesh.

Design/methodology/approach

A questionnaire survey about 27 frequently consumed food items was conducted among 140 patients in Amader Gram Cancer Care & Research Center. A logistic regression was applied to estimate breast cancer risk. Dietary patterns were analyzed by the principal component analysis: the fat-rich foods (meat, oil, etc.), fruits, vegetables, sugar, tea, coffee, eggs and fish patterns.

Findings

The marginal effect of the logit model estimated an increased risk of breast cancer for a“Fatty Diet”, characterized by a higher consumption of milk (1.2 per cent, p < 0.01), vegetable oils and fats, butter (3.7 per cent, p < 0.05) and red meat (4.9 per cent, p < 0.05), but a decreased risk of breast cancer for a “Fruity and Vegetable Diet”, characterized by a higher consumption of fish (1.3 per cent, p < 0.01), chicken and eggs (5.1 per cent, p < 0.05), fruits (0.05 per cent, p < 0.01) and vegetables (2.9 per cent, p < 0.05). The findings of this study also suggested that weight (0.07 per cent, p < 0.01) and age (19 per cent, p < 0.05) were associated with an increased risk of breast cancer, but exercise (13 per cent, p < 0.05) reduced breast cancer risk. The findings also showed that maximum patients had inadequate knowledge on dietary and clinical factors of breast cancer risk, in addition to poor cancer screening practice. Poor knowledge and practice of breast screening were likely to lead to late stage presentation of breast cancer.

Originality/value

The authors found an association between the prudent dietary patterns and breast cancer risk and poor knowledge on nutrition and breast cancer.

The purpose of this study is to evaluate the nutritional status of patients with end-stage kidney disease undergoing hemodialysis.

Abstract

Purpose

The purpose of this study is to evaluate the nutritional status of patients with end-stage kidney disease undergoing hemodialysis.

Design/methodology/approach

End-stage renal failure outpatients on hemodialysis were selected using simple random sampling technique from the dialysis unit of Sono Hospital Limited, Kushtia, Bangladesh. The nutritional status of 142 participant, of age 18-65 years, was screened. A direct method of nutritional assessment including anthropometric measurement, biochemical measurement, clinical assessment and dietary method was conducted. A logistic regression was applied to estimate the prevalence of malnutrition in hemodialysis patients.

Findings

In total 69.0 per cent participants were men and 31.0 per cent were women, whereas about 65.5 and 16.9 per cent patients of this study had a BMI of less than 23 kg/m2 and 18.5 kg/m2 (p < 0.05) where malnutrition was significantly prevalent. Mean ± SD hemoglobin level of both men and women participants was below the normal level which might increase the risk of malnutrition (p < 0.05). Of the total number of participants, 97.2 per cent were anemic, 66.9 per cent had anorexia, 63.4 per cent complained of nausea, 58.5 per cent complained of vomiting and 26.1 per cent complained of diarrhea, factors that can increase the risk of malnutrition in hemodialysis patients (p < 0.05). The creatinine and urea levels were higher in both men and women participants (p < 0.05). Results show significant difference in albumin levels among men and women (p < 0.05). The bicarbonate level was lower in both men and women, and the participants were suffering from metabolic acidosis (p < 0.05). About 87.3 per cent participants were taking inadequate amounts of protein which was a significant risk factor of malnutrition in hemodialysis patients (p < 0.01).

Originality/value

The result shows that renal failure is prevalent more in men than in women. The majority of patients on hemodialysis were at a risk of malnutrition including being underweight. Most of the patients were anemic. Malnutrition is related to low nutrient intake.

Abstract

Purpose

The purpose of this paper is to inspect the potential mediation pathways among emotional empathy, personality traits and coping strategies in orphan and non-orphan students. Additionally, it designed to investigate the association of coping strategies with emotional empathy and personality traits.

Design/methodology/approach

Purposive sampling technique and cross-sectional design were employed in current study. The data of 130 adolescents (institutionalized orphans, n= 62; school students, n=68) were included from different high schools and orphanages of Rawalpindi and Islamabad, Pakistan, in 2017. Three instruments, emotional empathy scale (Mehrabian and Epstein, 1972; Shazia, 2004), coping of problem experience (Carver, 1989; Akhtar, 2005), and Eysenck personality questionnaire (Naqvi and Kamal, 2010; Eysenck, 1964; Eysenck and Eysenck, 1994), were employed to measure personality traits, emotional empathy and coping strategies in orphan and non-orphan students.

Findings

Mediation analyses illustrated that personality traits relegated active avoidance coping strategy through emotional empathy in orphan students. On contrary, the study findings demonstrated that neurotic personality promoted positive coping strategy through emotional empathy in non-orphan students.

Research limitations/implications

The methodological limitations of this study are that the sample is of 130 participants that limits the generalizability of its results; furthermore, it was done on only the male orphans students of only one institute. Further research can be done on different orphanages to enhance the generalizability of results. This study included orphan and non-orphan students from the two cities of Pakistan; consequently, its findings may not be generalizable to the whole population. In the future, cross-sectional and experimental researches working with more assorted data could help elucidate the mechanisms by which interpersonal factors affect and stimulate coping strategies in orphans and high school students.

Practical implications

This paper exposes a number of ways for upcoming future studies. This study findings can be employed to enhance knowledge and offer assistance for orphans, on how to identify and get help from coping resources to tackle various problems and how to build new psychological preventions and interventions strategies in the Pakistani society. There still exists a need to find out the effect of emotion, empathy on personality types in relation to different environmental conditions. The findings have implications for pedagogical intervention as such improvements can be initiated in the pedagogical context.

Social implications

This study comprised only orphan and non-orphan students from two twin cities of Pakistan; consequently, its findings may not be applicable to the whole population. In future, cross-sectional and experimental researches with more assorted data will assist clarify the mechanism that interpersonal factors affect and stimulate coping strategies in high school students.

Originality/value

Study findings proposed that coping strategies can be promoted by interpersonal factors such as personality traits and empathy to tackle different orphan’s psychological problem in various negative situation.

Abstract

Purpose

The purpose of this paper is to investigate the mediating role of psychological problems (stress, anxiety, depression) between hearing impairment (HI) and tinnitus in tinnitus patients. Sample comprised of 110 patients (male, n=70; female, n=40).

Design/methodology/approach

The purposive sampling technique was used based on correlational design. Two scales, tinnitus handicap inventory developed by Newman et al. (1996), and depression, anxiety and stress scale developed by Lovibond and Lovibond (1995), were employed to assess tinnitus, anxiety, stress and depression among tinnitus patients.

Findings

The study revealed that tinnitus was positively significant correlated with depression (r=0.55, p<0.001), anxiety (r=0.63, p<0.001), stress (r=0.54, p<0.001) and hearing loss (r=0.81, p<0.001). The results also revealed that hearing loss was positively significant predictor for tinnitus (β=20.72, p<0.001). Further, it was revealed that tinnitus was positively significant predicted by anxiety (β=2.62, p<0.001), stress (β=2.33, p<0.001) and depression (β=2.71, p<0.001); the interaction between psychological symptoms and hearing loss was negatively significant predictor for stress (β=−0.51, p<0.001), anxiety (β=−0.57, p<0.001) and depression (β=−0.62, p<0.001). Moreover, it was revealed that female tinnitus patients were more predisposed to stress, anxiety and depression as compared to male tinnitus patients. Results also elaborated that those tinnitus patient who had profound HI were less inclined toward psychological problems as compared to those tinnitus patients who had mild to moderate level of HI. This study would be helpful for the clinical setting to tackle the psychological problems of tinnitus patients.

Research limitations/implications

This study consisted on population from urban cities of Pakistan; therefore, the findings cannot be generalized on overall population. In future, descriptive as well as experimental studies will be beneficial to describe the mechanism of tinnitus across gender in detail. Native tool for measuring gender-related problems would be effective in future as it integrates cultural aspects as well.

Originality/value

There is a consensus across researchers that tinnitus is one of the most important biological problem which initiates various other psychological problem (Minen et al., 2014; Vogel et al., 2014). Numerous studies have been conducted to find out the relationship of tinnitus with various psychological and biological factors (Boi et al., 2012; Li et al., 2014; Marciano et al., 2003; McCormack et al., 2015; Møller et al., 2010; Udupi et al., 2013; Zöger et al., 2006).

Abstract

Purpose

The purpose of this paper is to explore how heuristics are formed and whether herding and prospect theory act as antecedents to heuristics. The relationship is explored specifically for millennials.

Design/methodology/approach

The proposed relationship is explored specifically for millennials. Herding and prospect theory are modelled as antecedents to heuristics. The study uses survey data from 923 millennials from India to test the model for two financial products: equity and mutual funds. Regression analysis is used to evaluate the model.

Findings

Findings support the role of herding and prospect theory as antecedents to heuristics of millennials although to varying degrees for equity and mutual fund investments. The impact of herding on heuristics is likely to be smaller for equity investments as compared to mutual fund investments.

Research limitations/implications

The findings provide insights into how heuristics are formed for millennials. The findings add to literature by beginning a new line of inquiry on how heuristics are formed. Since the model is tested on a single generation, future research can test the model on other generations. In addition, future research can also add more antecedents to our proposed model.

Practical implications

Findings from this study can provide financial planners and marketers with an understanding of how heuristics are formed for millennials. Financial planners can use these insights while providing financial advice to this generation and marketers can use them to create more relevant outreach.

Social implications

Financial investments are an important conduit for financial security. By understanding the cognitive processes that influence financial investment decision-making, it is possible for educators to create content appropriately and for financial planners to advise clients accordingly to enable optimal financial decisions that will be wealth-creating.

Originality/value

Existing literature primarily treats heuristics, herding and prospect theory as being independent of each other. The authors take a novel approach to model the antecedents to heuristics to be herding and prospect theory. The model is tested on millennials for two financial products: equity and mutual funds.

Abstract

Purpose

In this study, the tri-bological behaviour of the un-coated and diamond coated tungsten carbide was evaluated using the pin-on-disc test rig. The same was also tested on a lathe machine tool. This paper aims to compare the tri-bological behaviour of coated tungsten carbide pin with un-coated tungsten carbide pin it also correlates the wear obtained from the two machines used.

Design/methodology/approach

Experiments were performed using L8 orthogonal array and results obtained on a pin-on-disc test rig under dry sliding process were optimized through a modern optimization technique i.e. genetic algorithm (GA). The response surface methodology model (L8 orthogonal array) formed the basis for the development of the GA model, which defines the conditions of minimum wear, minimum coefficient of friction and minimum surface roughness for the sliding process of the pin-on-disc test rig.

Findings

Implementation of the heuristic approach for optimization of input parameters for the combination of tool material used for the turning process. The initial approach involves tri-bological testing considering the same combination. The set of experiments further performed, inferred that the results were similar and that the diamond coating enhances the life of the tool.

Originality/value

Successfully synthesized the diamond coating on tungsten carbide tool material. Implantation of the heuristic approach, i.e. GA to tri-bological tests to identify the optimized level of input variables. Experimentation involves the tri-bological testing whose results were confirmed through performing experiments on the lathe machine tool.
