Abstract

Purpose

The purpose of this paper is to study the effect of chronic consumption of fresh palm oil (FPO) and thermoxidized palm oil (TPO) diet on gastric acid secretion, pepsin secretions, gastric mucus output and gastric cytoprotection.

Design/methodology/approach

Adult Wistar rats were randomly assigned into three groups, i.e. control, FPO and TPO groups (n = 10 in each). The control group was fed with normal rat chow only, the FPO group was fed on diet containing 15 per cent v/w FPO and the TPO group was fed with diet containing v/w of thermally oxidized palm oil. All animals had free access to feed and water, and the feeding lasted for 14 weeks. At the end of the feeding period, gastric acid secretion, pepsin secretion, mucus output and gastric ulceration were measured following standard methods.

Findings

There was increase in histamine-stimulated gastric acid output in the TPO diet-fed group (p < 0.01) compared with the control and FPO diet-fed groups. No significant change in the mucus output was observed across all the experimental groups; whereas, pepsin secretion was significantly higher (p < 0.05) in the TPO diet-fed group (0.46 ± 0.27) compared with the control (0.14 ± 0.05) and FPO diet-fed groups (0.25 ± 0.01). Ulcer scores in the TPO diet-fed group (15.5 ± 0.33) was significantly higher (p < 0.01) compared with the control (10.0 ± 0.05) and FPO diet-fed (5.0 ± 0.04) groups.

Originality/value

Chronic consumption of TPO increased gastric acid and pepsin secretion (gastric-aggressive factors) without a change in the mucus output. This can bring about gastric ulceration; therefore, the liberal use of TPO should be discouraged.

Abstract

In Nigeria, family is most important. It is usually made up of people who are related by blood, marriage, or adoption. Family plays a major role in influencing the use of psychoactive substances by adolescents and can help protect the adolescents or the reverse. Family differs in so many ways, for example, in the extent of support for education, children’s upbringing, monitoring peer activities among others. There are certain family situations where values are not being instilled, parental and social guides are not in place to ensure that children are well brought up. High levels of economic hardship (such as unemployment), family conflict, poor communication skills, domestic violence, parental divorce or single parenting, death, parental criminal activity among others disrupt parenting which reduces adolescents’ emotional security and reinforce the use of aggression and interpersonal hostility which in turn expose them to certain risks of psychoactive substance use. It is in this context that this chapter examines how family factors affect the use of psychoactive substances among adolescents in Nigeria. Empirical investigations were carried out through a review of literature search. The findings show family factors having a significant influence on the use of psychoactive substances among adolescents in Nigeria. In addition, proper parental relationship through training of moral values, teachings of the immense danger attributed to the use of psychoactive substances through counseling and communication skills could serve as a control measure that will discourage the future use and thus improve the health, safety and the general well-being of the adolescents.

Abstract

Purpose

Chronic feeding with thermoxidized palm oil causes tissue damage. The purpose of this paper is to ascertain whether chronic feeding of oxidized and fresh palm oil affects biliary secretion.

Design/methodology/approach

Albino Wistar rats were divided into three groups of ten rats each. The first group was the control and were fed on normal rat chow, while the second (FPO) and third group (TPO) were fed diet containing either fresh or thermoxidized palm oil (15per cent (w/w)) for 14 weeks. Biliary secretion, bilirubin, electrolytes, cholesterol and serum levels of alkaline phosphatase, aspartate aminotransferase and alanine aminotransferase enzymes were measured.

Findings

Biliary secretion in TPO was significantly (p < 0.05) lower compared with the control or FPO. Electrolytes (Na+, Cl and HCO3) content of bile were significantly (p < 0.05) lower in TPO compared with control or FPO group. Conjugated and un‐conjugated bilirubin levels were significantly (p < 0.05) elevated in TPO compared with control or FPO. The levels of serum liver enzymes were significantly (p < 0.001) higher in TPO than control or FPO. The cholesterol level in the TPO was significantly higher (p < 0.001) than in control or FPO.

Research limitations/implications

The non‐clinical approach and use of experimental animals present limitations to the study.

Originality/value

These results suggest that long‐term feeding of thermally oxidized palm oil alters bile composition and decreases biliary flow due to its hazardous free radicals.

Abstract

Purpose

This study aims to review the lived experience of patients suffering from stroke and describe their perception of palliative care needs.

Design/methodology/approach

A literature review search was conducted. Web of Sciences, SAGE, CINAHL, PubMed and Jordanian Database for Nursing Research databases were used to search the literature.

Findings

The findings of 37 articles were address palliative care approaches for patients with stroke, lived experiences of patients suffering from stroke and the experience, barriers and facilitators related to health-care service for stroke survivors.

Originality/value

This review indicated the importance of recognizing palliative care needs among patients suffering from stroke to improve post-stroke recovery. This study recommends further research, especially in low- and middle-income countries, to understand patients’ experiences and recognize the main palliative care needs that can be incorporated into interventions designed to improve the quality of life among them.

Abstract

Purpose

Depression and its symptoms negatively influence the health-related quality of life of patients. This paper aims to explore the occurrence of depressive symptoms and their relationship with health-related quality of life and sociodemographic characteristics.

Design/methodology/approach

It was a cross-sectional study conducted among patients attending the outpatient psychiatric clinics of two Nigerian hospitals. Data were collected using sociodemographic, PHQ-9 and 15 D questionnaires from a convenience sample of patients. Statistical Product and Services Solution Software (SPSS) version 21.0 was used to evaluate depressive symptoms, health-related quality of life, sociodemographic characteristics and the associations among them.

Findings

The mean depressive symptoms and health-related quality of life scores were found to be 12.118 ± 4.373 and 0.829 ± 0.141, respectively. The result showed a significant negative correlation (r = −0.318, p < 0.001) between respondents’ depressive symptoms and health-related quality of life. Patients with comorbid conditions reported a significantly higher level of depressive symptoms (p = 0.002) and lower health-related quality of life (p < 0.001). There was a significant difference in the mean health-related quality of life of the respondents across their level of education and marital status.

Originality/value

Depressive symptoms are a common occurrence in psychiatric conditions. This study provides an insight into the associations between depressive symptoms, socio-demographic factors and the health-related quality of life of psychiatric patients in a low-income country.

Abstract

Purpose

Alcohol and tobacco consumption are significant public health concerns and considered some of the riskiest behaviors among students. Despite strong indications of heavy consumption of these substances, certain sections of the student population remain unexplored regarding their consumption patterns and associated factors, including research scholars pursuing Doctor of Philosophy degrees. This study aims to explore the patterns and correlations of consumption of alcohol and tobacco among doctoral students in three Indian universities.

Design/methodology/approach

A cross-sectional study was conducted on a total of 530 scholars from three central universities, Aligarh Muslim University, Banaras Hindu University and Jawahar Lal Nehru University, and focused on two substances (alcohol and tobacco) frequently used by students in India. Bi-variate analysis and penalized logistic regressions were applied to analyse the prevalence and associated factors of alcohol, smoking and smokeless tobacco among doctoral students.

Findings

Tobacco consumption was observed to be the dominant form of substance use among doctoral students. Findings revealed that 34% of scholars smoked and 25% consumed smokeless tobacco daily and around 14% consumed alcohol at least once a week. Major significant correlates of substance consumption among scholars were found to be gender, religion, parental mortality, dissatisfaction with academic performance and stress about future career/employment. Significant variation in substance use patterns was observed among universities.

Originality/value

This study provides first-hand evidence on substance use patterns and the correlates among doctoral students in three Indian universities. Findings indicate the implementation of specific intervention programs for mental health and counselling for this section of students to prevent substance use addiction would be beneficial.

Abstract

Purpose

The purpose of this study is to explore the influence of harmful cultural practices and its implications on stigmatization and the spread of HIV infection among people diagnosed with HIV in North Central Nigeria. It will help to identify the cultural values that pose a threat to the social, health and psychological well-being of the members of the society. This study will provide recommendations through educational teachings to community leaders and policymakers for health-care protection through Human Rights Act.

Design/methodology/approach

This study uses the qualitative phenomenological research design through a face-to-face in-depth interview to collect data using the audio recorder and field notes. Purposive sampling technique was used to recruit, from three selected hospitals, 20 participants aged 18 years–56 years who gave their consent by filling the informed consent form between April 2019 and July 2019. The data collected were analyzed through thematic analysis using ATLAS.ti 8 software. Also, thematic network analysis was used to visualize the themes, sub-themes and quotations.

Findings

The study findings indicate that sociocultural factors and HIV stigma in Nigeria are significant psychosocial problems that have adverse implications for health and psychological well-being. These problems contribute to the harmful traditional practices, thereby making people vulnerable to contracting HIV infection. The nontherapeutic practices of female genital mutilation, sexual intercourse during menstruation and tribal marks or scarification cause medical complications such as vesicovaginal fistula, rectovaginal fistula and HIV infection. Also, the practice of 18 months of sexual abstinence during breastfeeding predisposes couples to extramarital affairs and HIV infections. The findings also reveal that lack of education contributes to gender inequality.

Originality/value

The research uses a scientific method using ATLAS.ti 8 software for the transcription, organization and thematic analysis of the qualitative data. The study findings will benefit specifically the young girls and women who are usually the victims of the harmful cultural practices of female genital mutilation, gender inequality, sexual intercourse during menstruation and lack of female education in North Central Nigeria. Also, this study will serve as a relevant document and guide for policy implementation of Human and Child Rights Acts against all harmful cultural practices and gender inequality.

Abstract

Purpose

The purpose of this paper is to examine the asymmetric behavior between CEO pay and firm performance in Nigeria.

Design/methodology/approach

The study adopts a two-step dynamic panel generalized method of moments (GMM) to reveal asymmetric responses of CEO pay to positive and negative shocks in firm performance.

Findings

The research outcomes of a two-step dynamic panel GMM) adopted reveal asymmetric responses of CEO pay to positive and negative shocks in firm performance. This implies that CEOs are handsomely compensated for good performance, but not punished for poor performance.

Originality/value

The study, therefore, suggests that CEO pay fails to serve as an internal corporate governance mechanism to alleviate agency problem in Nigeria’s listed firms.

Abstract

Purpose

The purpose of this paper is to examine the nature of interactive effect of competition and corporate governance on productivity growth of firms in Nigeria. Studies that have considered this issue were mainly from developed countries possessing strong institutions as against those of developing countries like Nigeria. Moreover, studies from Nigeria have focused exclusively on corporate governance and firm performance. The interaction effect of competition on corporate governance is yet to be addressed in the context of Nigeria.

Design/methodology/approach

The study adopts the dynamic panel data analysis approach suggested by Arellano and Bond for productivity growth analysis. Data on 76 non-financial firms for 11 years beginning from 1997 were extracted from the financial statements of companies collected from the Nigerian Stock Exchange and subsequently analysed using General Methods of Moments (GMM).

Findings

The results show that competition had a positive impact on productivity growth, however, its interaction effect with corporate governance had a substitute but not significant impact on productivity growth. When competition was interacted with an alternative corporate governance mechanism – bank – a positive and significant impact was, however, observed which shows that competition and bank loans are complementary in stimulating productivity growth of firms in Nigeria.

Research limitations/implications

The study could not be carried out beyond year 2007 owing to the exit of some firms after 2007 which could have reduced the sample size drastically. The findings emanating from this study suggests that government should focus much more on implementing competitive policies and bother less on writing corporate governance codes.

Practical implications

The results demonstrate that corporate governance had no significant impact on productivity growth even when it was interacted with competition. However, competition on its own had a significant impact on productivity which means that Nigeria should concentrate more on building a competitive private sector, and in this regard, government should try and pursue policies that will foster competition and eliminate monopolistic tendencies. Once, there is effective competition, the corporate governance may be strengthened. However, the interactive effect of competition and bank loans was found with a positive and significant impact which indicates that banks as alternate corporate governance mechanism can only be effective if competition is strong. This goes to show that the financial sector may not be able to effectively and positively impact the real sector in Nigeria if the prevailing level of competition is low. In such a situation finance may not be channelled to projects that have long-run implications on sustainable growth and development.

Social implications

Socially, if the environment for competition is not fostered in Nigeria, the country may face an uphill task in combating the problem of poverty through a private sector-led solution. Hence, there is a need for government to begin to formulate comprehensive competition policies that will ensure that resources are optimally utilized in Nigeria.

Originality/value

In the context of Nigeria, this study is novel, the use of productivity growth as against firm financial performance is unique for Nigeria while the use of GMM method of analysis helps in reducing the effect of endogeneity inherent in corporate governance and performance of firms in Nigeria.

Abstract

Purpose

The purpose of this paper is to investigate consensus formation among the top and middle managers during the strategy process. Specifically, the paper seeks to gain insight into the role of strategic consensus during the transition between strategy formulation and implementation.

Design/methodology/approach

Adopting a social practice perspective and a single case study approach, we undertook semi-structured interviews of twenty-seven managers working in a Kuwaiti Ministry. Data collected were analyzed using thematic analysis.

Findings

We found that social interaction among individuals with similar characteristics and shared understanding fosters consensus. Factors such as alignment of strategic priorities, managerial flux and centralized control contribute to the extent to which strategic consensus is achievable. Additionally, managerial turnover and lack of empowerment hamper the development of shared understanding. Finally, that consensus on strategy content is insufficient for effective intergroup communications.

Originality/value

The research contributes to the strategic consensus literature from a social practice perspective as it provides new insights into the dynamics between top managers and middle managers. Significantly, it highlights the importance and need for common understanding, as well as communications prioritization among managers for consensus development and successful implementation of organization strategy.
