Stigmatization of AIDS patients : disentangling Thai nursing students' attitudes towards HIV/AIDS, drug use and commercial sex

This paper analyzes the interrelationships between the stigma of HIV/AIDS stigma and the co-stigmas of commercial sex (CS) and injecting drug use (IDU). Students of a Bangkok nursing college (N = 144) were presented with vignettes describing a person varying in the disease diagnoses (AIDS, leukemia, no disease) and co-characteristics (IDU, CS, blood transfusion, no co-characteristic). For each vignette, participants completed a social distance measure assessing their attitudes towards the hypothetical person portrayed. Multivariate analyses showed strong interactions between the stigmas of AIDS and IDU but not between AIDS and CS. Although AIDS was shown to be stigmatizing in and of itself, it was significantly less stigmatizing than IDU. The findings highlight the need to consider the non-disease-related stigmas associated with HIV as well as the actual stigma of HIV/AIDS in treatment and care settings. Methodological strengths and limitations were evaluated and implications for future research discussed.

Lived experience of gay men caring for others with HIV/AIDS : living, loving and dying in the era of HIV/AIDS

This thesis explored gay male carers’ experience of caring for their partner, brother or friend who had HIV/AIDS. Through using phenomenological methodology (van Manen, 1990), the day-to-day caring experiences were uncovered. The data gathered were then analysed through a nursing ‘lens’, with the concept of stigma as an anchoring point. The dual stigmas of homophobia and AIDS phobia impacted on the daily lives of these men as they cared for their loved one. The research identified six themes. These were: 1) the relationship; 2) coping with HIV and AIDS; 3) the corporal impact of HIV/AIDS; 4) experiences of carers including the absence of others; 5) living daily with the virus: Demands of people living with HIV/AIDS (PLWHA); and 6) saying goodbye, but wanting to keep the memory alive. The caring these men undertook, for which they were frequently unprepared, was intensive and complex, but because of their commitment and love they battled on. Because of a sense of shame associated with AIDS phobia on the part of the PLWHA, the carer often had to undertake this care in isolation, without support from family, friends or home health care agencies. The carers struggled with not only the demands of day-to-day care, but also with non-acceptance from family, both of the nature of the relationship with their partner and of their homosexuality. Family members were forced, often with great difficulty, to acknowledge the close commitment the men had to each other. Recognition that one had a terminal disease, HIV/AIDS was also required. The fear of potential transmission was high among carers, friends and family members. Notably, there was an absence of blame on the part of the carer towards his partner for contracting HIV/AIDS. The physical decline and marking of the body further stigmatised the PLWHA, which added to carers’ burdens. They endeavoured to minimise the physical decline in their partner, so he could continue to pass as healthy, and attempted to make the day-to-day living as normal as possible. The methods of combating weight loss and opportunistic infections meant frequent medical appointments, complex intensive medical procedures and help with personal care, which was undertaken at home largely without support from health care staff. Carers frequently struggled also with their partner’s denial of being ill. One strategy all carers used was to escape with their partners from their everyday life in Melbourne and attempt metaphorically to leave the HIV/AIDS behind; this was a time when they could rekindle their life together as it was before HIV/AIDS came into their lives. Some carers chose to holiday without their partner, to give themselves a break from the day-to-day caring, while others planned and took holidays with their partner. The decline of the health in the PLWHA meant that family members had to recognise and accept both the nature of the relationship and the presence of the disease. This recognition and acceptance often came only when the partner was very ill, even at the point of dying. Carers and their partners discussed the potential use of euthanasia, as a means of ending the final phase of life with some dignity. One carer and his partner used euthanasia, despite its illegal status. The main concern for all carers was providing comfort and a reduction in the pain associated with HIV/AIDS for the partner. The widespread grief associated with HIV/AIDS was evident amongst these carers. All had known other gay men who had died, some carers own partner had died, or was about to die. There was an overwhelming sense of grief, which at times was repressed as a means of coping day-to-day. All carers felt it was important and necessary to remember those lost to HIV/AIDS through the various public memorials, as they did not want their partner to be just another faceless person lost to this disease. This phenomenological study of carers’ experience highlights the need for health care workers to be aware of the differing strategies that gay men use to cope with HIV/AIDS. While it may seem that the carers are coping with care of their partner, the outer façade is not always an accurate portrayal of the true situation. Health care workers should enquire as to the assistance these carers need from health care services in order to continue to care for their loved one. Such assistance can be the simple recognition of the partner and acceptance of them as part of the PLWHA’s network; this inclusion and acceptance is half the battle.

Syphilis and AIDS : historical and social comparisons

Drawing on the literatures of history, sociology, epidemiology, and microbiology, this thesis compares syphillis with human immunodeficiency virus, with special reference to the social and historical factors likely to be relevant to the control or eradication of acquired imune dificiency syndrom (AIDS). The sudden appearance of a new disease causing suffering and death in a community, engenders apprehension and fear which is often manifested as hysteria against, and vilification of, those who have the disease. This fear is greatly increased should the disease be sexually-transmitted. Syphilis in a venereal form, occured in Europe toward the end of the 15th Century. Initially it was an acute, fulminating disease which rapidly spread through Europe and Asia. Attempts to control the disease have gone through periods of either partial successes or massive failures and have ended in frustration for the authorities. When the syndrome of acquired immune deficiency (AIDS) was first reported, it was seen in Western countries in homosexual men. However, as non-homosexual community members and children became infected, it became apparent to authorities that a pandemic was accurring. Within a few years, the disease was identified worldwide. Isolation of the virus (HIV-1), and development of test for detection of carriers, plus restoration of clean blood and blood-product supplies, have reassured the community to some extent. The history of syphilis shows that neither the epidemiological medical, nor the economic political approaches to disease control work, although there are positive aspects resulting from both. It is social responses that will offer the most hope in the long term for the control of AIDS and other sexually-transmitted diseases.

Effectiveness of an HIV / AIDS prevention approach across three countries

The study examined the effectiveness of one community based HIV / AIDS prevention approach, Community Counselling, in PNG, India and Zambia. Results indicated the three countries differed along cultural dimensions. Differences on behaviour, attitude, knowledge and risk perceptions associated with HIV / AIDS were noted within each country that reflected exposure to the approach. The professional portfolio examines the curent situations in which cultural guidelines have been developed to assist clinicians in considering indigenous cultural differences in increasingly multicultural societies. Four case studies are presented in which aspects of these issues are identified and discussed.

From globe to ground women, HIV & AIDS and Papue New Guinea

This thesis explored the HIV/AIDS epidemic in Papua New Guinea with a focus on women. The research drew upon principles of health promotion in shaping an analysis of models of prevention and technical support. The findings demonstrate the role of globalization, poverty, gender inequality and technical assistance in shaping vulnerability to HIV in Papua New Guinea.

Disentangling the layering of HIV/AIDS-related stigma

This thesis highlights the complexity of the inter-relationships between the disease stigma of HIV/AIDS and common modes of HIV transmission, such as injecting drug use, among health professionals in Asia. New ways of deconstructing disease-related stigma were explored. The findings pose challenges for the conventional approaches to HIV/AIDS stigma intervention.

Mining frequent patterns for AMP-activated protein kinase regulation on skeletal muscle

Background
AMP-activated protein kinase (AMPK) has emerged as a significant signaling intermediary that regulates metabolisms in response to energy demand and supply. An investigation into the degree of activation and deactivation of AMPK subunits under exercise can provide valuable data for understanding AMPK. In particular, the effect of AMPK on muscle cellular energy status makes this protein a promising pharmacological target for disease treatment. As more AMPK regulation data are accumulated, data mining techniques can play an important role in identifying frequent patterns in the data. Association rule mining, which is commonly used in market basket analysis, can be applied to AMPK regulation.

Results
This paper proposes a framework that can identify the potential correlation, either between the state of isoforms of α, β and γ subunits of AMPK, or between stimulus factors and the state of isoforms. Our approach is to apply item constraints in the closed interpretation to the itemset generation so that a threshold is specified in terms of the amount of results, rather than a fixed threshold value for all itemsets of all sizes. The derived rules from experiments are roughly analyzed. It is found that most of the extracted association rules have biological meaning and some of them were previously unknown. They indicate direction for further research.

Conclusion
Our findings indicate that AMPK has a great impact on most metabolic actions that are related to energy demand and supply. Those actions are adjusted via its subunit isoforms under specific physical training. Thus, there are strong co-relationships between AMPK subunit isoforms and exercises. Furthermore, the subunit isoforms are correlated with each other in some cases. The methods developed here could be used when predicting these essential relationships and enable an understanding of the functions and metabolic pathways regarding AMPK.

Learning dependency model for AMP-activated protein kinase regulation

The AMP-activated protein kinase (AMPK) acts as a metabolic master switch regulating several intracellular systems. The effect of AMPK on muscle cellular energy status makes this protein a promising pharmacological target for disease treatment. With increasingly available AMPK regulation data, it is critical to develop an efficient way to analyze the data since this assists in further understanding AMPK pathways. Bayesian networks can play an important role in expressing the dependency and causality in the data. This paper aims to analyse the regulation data using B-Course, a powerful analysis tool to exploit several theoretically elaborate results in the fields of Bayesian and causal modelling, and discover a certain type of multivariate probabilistic dependencies. The identified dependency models are easier to understand in comparison with the traditional frequent patterns.

Shake rattle and roll: a journey with Parkinson's

This is the journey of a man suffering from Parkinson's disease. Ross Collins tells of his past twelve years' experiences of living with Parkinson's. Before, he had a steady job with Victoria Police, with promising future prospects; and was happily married with two young children. The disease struck him at an early age, changing his life and setting him on a different course. His outlook on life has changed, and his decision-making influenced; as well, his relationships with his family affected. He feels normal only when he is shaking, rattling and rolling along on his Harley. His wish for a cure leads him to pin his hopes on faith healing by the 'miracle man', in Brazil. The first two visits did not seem to have done anything to improve his physical condition. Ross is returning to Brazil for the third time, hoping against hope that his condition could be improved by a miracle healing. This documentary gives an intimate look into the life of a Parkinson's disease sufferer and that of his family. Includes al.

Cultural ways of knowing

As a strategic response to HIV, this research made a significant contribution to the development of effective models of translation - from a rhetoric of lived experiences of HIV to social, political and cultural change. This brought benefits to areas such as HIV health promotion and education, practice and policy.

Children’s experiences of acute hospitalisation to a paediatric emergency and assessment unit – A qualitative study

Short-stay treatment has become a popular form of care as a strategy to cope with increased demands on health care. There is little research that considers children’s experiences of acute hospitalisation to a short-stay care facility such as a Paediatric Emergency and Assessment Unit (PEAU). This study explored the experiences of eight children aged 8–10 years. Semi-structured interviews were carried out to investigate the children’s own experiences of being hospitalised in a PEAU. Thematic content analyses were used. Three major themes were identified: the children’s understanding of disease, treatment and procedures; the children’s experiences of health-care personnel and the PEAU and transformation of everyday life into the settings of the hospital. The children identified the hospital stay as an overall positive experience. The children took part in leisure activities as they would at home and enjoyed time together with their parents while in hospital. In their conversations with staff they adapted to professional terms that they did not necessarily understand. They did not differentiate between professionals. Further work should be considered to clarify the consequences of this. This study has provided some limited insight into the child’s experiences of acute hospitalisation, which should inform nursing care.

Medication compliance and satisfaction with treatment for HIV disease in a sample of African-American crack cocaine smokers

The development of treatment regimes for African-American HIV-infected crack cocaine users has often been based on assumptions about compliance with medication regimes rather than evidence. This study sought to obtain baseline information on the adherence to antiretroviral medications by members of this important risk population in Houston, Texas. It was found that for only 5 of a range of 16 antiviral medications was there a significant correlation between levels of compliance reported by respondents and their beliefs as to how effective these medications are. Medication compliance was also found not to be associated with frequency of crack cocaine use in the month prior to interview. Furthermore, irrespective of both gender and their reported extent of medication compliance, the respondents tended to report positive relationships with their treating physician, with higher levels of satisfaction reported by women. These results suggest that the majority of African-American crack cocaine users are able to comply with HIV treatment regimes, with more than half (53%) claiming full compliance for one or more medications, and a further one third (31%) claiming compliance more than half the time. Moreover, these findings suggest that they will continue to take antiretroviral medications even if they have doubts about the effectiveness of these medications.

Ischaemic heart disease and Australian immigrants: the influence of birthplace and language skills on treatment and use of health services

Admission rates for ischaemic heart disease (IHD), and the use of invasive cardiovascular procedures, separation mode and length of stay (LOS) were compared between Australians from non-English speaking background (NESB; n=8627) and English speaking background (ESB; n=13162) aged 20 years and over admitted to Victorian urban public hospitals. The study covered the period from 1993 to 1998. It was found that, compared with their ESB counterparts, the incidence of admission for acute myocardial infarction was significantly higher for NESB men and women before and after controlling for confounding factors. The age-adjusted ratios for NESB women compared with their ESB counterparts ranged from 1.23 to 1.89 for cardiac catheterisation, from 0.23 to 0.27 for percutaneous transluminal coronary angioplasty (PTCA), and from 1.04 to 1.80 for coronary artery bypass grafting (CABG).
Procedure rates were comparable in men for cardiac catheterisation and CABG but higher for PTA rates in NESB men (OR: 1.29, 95%CI: 1.11-1.50) than their ESB counterparts. Both NESB men (β=0.04, 95%CI: 0.01-0.07) and women (β=0.03, 95%CI: 0.02-0.08) experienced significantly longer hospital stays than their ESB counterparts. These findings indicate there may be systematic differences in patients’ treatment and service utilisation in Victorian public hospitals. The extent to which physicians’ bias and
patients’ choice could explain these differences requires further investigation.

Stigmatization of patients with AIDS : understanding the interrelationships between Thai nurses' attitudes towards HIV/AIDS, drug use and commercial sex

There is currently a scarcity of research on the nature of HIV/AIDS stigma within the Thai health context. This is problematic given the negative role of stigma in hindering the provision of patient care and treatment. This study used a mixed-method approach to investigate the interrelationships between the stigma of HIV/AIDS and the stigmas relating to its various modes of disease transmission including injection drug use (IDU). Twenty interviews were conducted with trainees and qualified nurses from a Bangkok college. Participants were presented with vignettes describing a hypothetical person varying in disease diagnoses (AIDS, leukemia, no disease) and co-characteristics (IDU,  commercial sex (CS), blood transfusion, no co-characteristic). Using a Q-sort task, participants arranged the vignettes along a bipolar scale according to their willingness to interact with the persons, and were asked to explain their decisions. Univariate and multivariate regression analyses showed that IDU, AIDS, and CS were all individually stigmatizing. Strong interactions were found between the stigmas of HIV/AIDS, IDU, and CS. Interview data also showed clear biases toward patients according to their IDU and CS habits. The findings  suggest that addressing these co-stigmas could be vital to the success of efforts aimed at reducing the disease stigma of HIV/AIDS.
