Abstract:
This article discusses a dynamical analysis of the fractional-order model of HIV/AIDS. Biologically, the rate of subpopulation growth also depends on all previous conditions/memory effects. The dependency of the growth of subpopulations on the past conditions is considered by applying fractional derivatives. The model is assumed to consist of susceptible, HIV infected, HIV infected with treatment, resistance, and AIDS. The fractional-order model of HIV/AIDS with Caputo fractional-order derivative operators is constructed and then, the dynamical analysis is performed to determine the equilibrium points, local stability and global stability of the equilibrium points. The dynamical analysis results show that the model has two equilibrium points, namely the disease-free equilibrium point and endemic equilibrium point. The disease-free equilibrium point always exists and is globally asymptotically stable when the basic reproduction number is less than one. The endemic equilibrium point exists if the basic reproduction number is more than one and is globally asymptotically stable unconditionally. To illustrate the dynamical analysis, we perform some numerical simulation using the Predictor-Corrector method. Numerical simulation results support the analytical results.

Abstract:
System dynamics models can facilitate the understanding of complex and dynamic biomedical systems such as in HIV/AIDS. Untangling the dynamics among various population stocks (e.g., susceptible population, infected population, HIV population, AIDS population) can be used to investigate the effective points of interventions in the HIV/AIDS cycle. With that in mind, the authors have developed a system dynamics model that can be used to examine various policy decisions for the prevention and the treatment of HIV/AIDS. The specific objectives of their study was to examine the growing number of AIDS-related deaths in Canada. They used the authors’ dynamic simulation model to evaluate the impact of various HIV/AIDS policy intervention scenarios centred on the reduction of the number of AIDS deaths in Canada. Their analysis suggests that more lives will be saved if effective preventive and treatment programs are implemented simultaneously. A simultaneous implementation of these programs will also result in a much smaller HIV-infected and AIDS populations.

We had constructed mathematical model of HIV/AIDS with seven compartments. There were two different stages of infection and susceptible subpopulations. Two stages in infection subpopulation were an HIV-positive with consuming ARV such that this subpopulation can survive longer and an HIV-positive not consuming ARV. The susceptible subpopulation was divided into two, uneducated and educated susceptible subpopulations. The transmission coefficients from educated and uneducated subpopulations to infection stages were where (( and ) ( and )) In this paper, we consider the case of and were zero. We investigated local stability of the model solutions according to the basic reproduction number as a threshold of disease transmission.

HIV/AIDS is a very dangerous disease. The transmission of HIV/AIDS can be in three ways and one of them through a syringe. In this paper we describe SIR and SEIR Host-Vector model transmission of HIV/AIDS amongst populations of injecting drug users. From the existing model we obtained disease-free equilibrium point and endemic equilibrium point. Then we study the stability conditions and sensitivity analysis of the . The analysis shows if then the disease-free equilibrium point is stable and if then the endemic equilibrium point will be stable. We also obtained that parameter of probality host-vector infected with HIV/AIDS affects the increase of number infected HIV/AIDS.

Abstract:
Objectives: To examine the awareness regarding HIV/AID and sexual behaviouramong long distance truck drivers (LDTDs) in Bahawalpur division. Study design: A crosssectional population study. Setting: Three districts (Bahawalpur, Bahawalnagar and RYK).Data: Sample of size of 120 LDTDs is taken by using convenient sampling technique. Methods:Descriptive and inferential analysis carried out. Results: Every 6 out of 10 LDTDs have heardaboutHIV/AIDS and believed that sexual intercourse is a major mode of its transmission. Theuse of condom before sex is seldom among truckers. Exactly half of LDTDs have only onesexual partner while nearly quarter (23.3%) of the respondents currently having two sexualpartners. Over half (54.2%) of truckers made payment for sex with commercial sex workers(CSWs) and only 3.3% did so with their helper/conductor. Two models are executed separatelyto explore the association of trucker’s knowledge about HIV/AIDS (Model 1) and those whopaid for sex (Model 2). Pearson chi-square analysis exhibits that respondents having age group25-30 year, those with native of Punjabi language, those who manage to earn more than 15,000Pakistani rupees per month, those having secondary level of schooling and those watchingTV has higher knowledge regarding HIV/AIDS. LDTDs with age thirty years and over, Saraikispeaking, monthly income less than 10,000, illiterate, unmarried, watching TV and remainaway from home during current trip a week are found to be more prone to pay for sex toCSW. Conclusions: The awareness of HIV/AIDS and knowledge of its transmission throughsexual contact is high among LDTDs but still public health strategies are needed to promotethe knowledge of all possible transmission modes of HIV/AIDS and use of condom before sex,ultimately to improve health outcomes.

Abstract:
In this Paper, a staged-progression model for HIV/AIDS transmission dynamics is formulated and analyzed to study the impact of Screening, Condom usage and Condom compliance. The local stability for the disease free equilibrium (DFE) was proved for Rc < 1 and Kransnoselki sublinearity trick was used to show that the endemic equilibrium (EE) is locally asymptotically stable for a special case whenever Rc > 1. Numerical simulation was also carried out to investigate the effects of screening unaware (unscreened) asymptomatic individuals and Condom compliance. The result shows the influence of condom compliance and screening on the transmission dynamics of HIV/AIDS. The result clearly shows that increase in the compliance of Condom usage and increase of screening rate of HIV individuals reduces the total number of HIV/AIDS individuals. This point that increase in Condom usage and screening reduces HIV/AIDS burden.

Abstract:
In the paper, we have considered a nonlinear compartmental mathematical model that assesses the effect of treatment on the dynamics of HIV/AIDS and pneumonia coinfection in a human population at different infection stages. Our model revealed that the disease-free equilibrium points of the HIV/AIDS and pneumonia submodels are both locally and globally asymptotically stable whenever the associated basic reproduction numbers ( R H and R P ) are less than unity. Both the submodel endemic equilibrium points are locally and globally asymptotically stable whenever the associated basic reproduction numbers ( R P and R H ) are greater than unity. The full HIV/AIDS-pneumonia coinfection model has both locally and globally asymptotically stable disease-free equilibrium points whenever the basic reproduction number of the coinfection model R H P is less than unity. Using standard values of parameters collected from different kinds of literature, we found that the numerical values of the basic reproduction numbers of the HIV/AIDS-only submodel and pneumonia-only submodel are 17 and 7, respectively, and the basic reproduction number of the HIV/AIDS-pneumonia coinfection model is max 7 , 17 = 17 . Applying sensitive analysis, we identified the most influential parameters to change the behavior of the solution of the considered coinfection dynamical system are the HIV/AIDS and pneumonia transmission rates β 1 and β 2 , respectively. The coinfection model was numerically simulated to investigate the stability of the coinfection endemic equilibrium point, the impacts of transmission rates, and treatment strategies for HIV/AIDS-only, pneumonia-only, and HIV/AIDS-pneumonia coinfected individuals. Finally, we observed that numerical simulations indicate that treatment against infection at every stage lowers the rate of infection or disease prevalence.

Abstract:
The issues of capacity and capacity development in the response to HIV and AIDS is a topic of intense academic interest and is on the agenda of development practitioners, particularly as these issues are linked to community HIV and AIDS competence and sustainability of civil society organisations and community capacity. The capacity development model of the Southern African AIDS Trust is one of the more illuminating examples of capacity development of civil society organisations for the enhancement of community HIV and AIDS competence in southern Africa. The thesis examines the conceptualisation and implementation of the Southern African AIDS Trust's capacity development model in order to identify and understand the multi-dimensional factors that influence the success and sustainability of HIV and AIDS responses. It argues that, even though the conceptualisation, formulation and implementation of the model were appropriate and yielded acceptable benefits to communities in relation to HIV and AIDS, the sustainability of the model depended fundamentally on the availability of requisite resources. The dependence on external resources, the availability of which is in large part beyond the control of the Southern African AIDS Trust and its community-based beneficiaries, undercuts the sustainability of the model and the programmes delivered through it. Community capacities and community-based HIV and AIDS responses are sustainable only to the extent that communities have sufficient resources to build capacities and develop responses, or can leverage and negotiate external inputs. The degeneration of capacity in intermediary organisations (such as Southern African AIDS Trust) that support community competence undermines models that at first sight seem suitable for effective capacity enhancement with regard to HIV and AIDS programmes. In this regard, the thesis also focuses on the organisational crisis within Southern African AIDS Trust and the ramifications this had for community HIV and AIDS competence.

In this thesis, we investigate the HIV/AIDS epidemic in a population which experiences a significant flow of immigrants. We derive and analyse a math- ematical model that describes the dynamics of HIV infection among the im- migrant youths and intervention that can minimize or prevent the spread of the disease in the population. In particular, we are interested in the effects of public-health education and of parental care.We consider existing models of public-health education in HIV/AIDS epidemi-ology, and provide some new insights on these. In this regard we focus atten-tion on the papers [b] and [c], expanding those researches by adding sensitivity analysis and optimal control problems with their solutions.Our main emphasis will be on the effect of parental care on HIV/AIDS epidemi-ology. In this regard we introduce a new model. Firstly, we analyse the model without parental care and investigate its stability and sensitivity behaviour.We conduct both qualitative and quantitative analyses. It is observed that in the absence of infected youths, disease-free equilibrium is achievable and is asymptotically stable. Further, we use optimal control methods to determine the necessary conditions for the optimality of intervention, and for disease eradication or control. Using Pontryagin’s Maximum Principle to check the effects of screening control and parental care on the spread of HIV/AIDS, we observe that parental care is more effective than screening control. However, the most efficient control strategy is in fact a combination of parental care and screening control. The results form the central theme of this thesis, and are included in the manuscript [a] which is now being reviewed for publication. Finally, numerical simulations are performed to illustrate the analytical results.

Abstract:
Philosophiae Doctor - PhD
The HIV/AIDS pandemic has been a torment to the African developmental agenda, especially the Southern African Development Countries (SADC), for the past two decades. The disease and condition tends to affect the productive age groups. Children have also not been spared from the severe effects associated with the disease. The advent of antiretroviral treatment (ART) has brought a great relief to governments and patients in these regions. More people living with HIV/AIDS have experienced a boost in their survival prospects and hence their contribution to national developmental projects. Survival analysis methods are usually used in biostatistics, epidemiological modelling and clinical research to model time to event data. The most interesting aspect of this analysis comes when survival models are used to determine risk factors for the survival of patients undergoing some treatment or living with a certain disease condition. The purpose of this thesis was to determine prognostic risk factors for patients' survival whilst on ART. The study sought to highlight the risk factors that impact the survival time negatively at different survival time points. The study utilized a sample of paediatric and adult datasets from Namibia and Zimbabwe respectively. The paediatric dataset from Katutura hospital (Namibia) comprised of the adolescents and children on ART, whilst the adult dataset from Bulawayo hospital (Zimbabwe) comprised of those patients on ART in the 15 years and above age categories. All datasets used in this thesis were based on retrospective cohorts followed for some period of time. Different methods to reduce errors in parameter estimation were employed to the datasets. The proportional hazards, Bayesian proportional hazards and the censored quantile regression models were utilized in this study. The results from the proportional hazards model show that most of the variables considered were not signifcant overall. The Bayesian proportional hazards model shows us that all the considered factors had different risk profiles at the different quartiles of the survival times. This highlights that by using the proportional hazards models, we only get a fixed constant effect of the risk factors, yet in reality, the effect of risk factors differs at different survival time points. This picture was strongly highlighted by the censored quantile regression model which indicated that some variables were significant in the early periods of initiation whilst they did not significantly affect survival time at any other points in the survival time distribution. The censored quantile regression models clearly demonstrate that there are significant insights gained on the dynamics of how different prognostic risk factors affect patient survival time across the survival time distribution compared to when we use proportional hazards and Bayesian propotional hazards models. However, the advantages of using the proportional hazards framework, due to the estimation of hazard rates as well as it's application in the competing risk framework are still unassailable. The hazard rate estimation under the censored quantile regression framework is an area that is still under development and the computational aspects are yet to be incorporated into the mainstream statistical softwares. This study concludes that, with the current literature and computational support, using both model frameworks to ascertain the dynamic effects of different prognostic risk factors for survival in people living with HIV/AIDS and on ART would give the researchers more insights. These insights will then help public health policy makers to draft relevant targeted policies aimed at improving these patients' survival time on treatment.

Abstract:
Human Immune Virus (HI)V /Acquired Immune Deficiency Syndrome (AIDS) has emerged as the most devastating epidemic that the world has experienced. Voluntary counselling and testing (VCT) has proven to be an effective way of preventing and controlling HIV. South African universities provide free VCT services on their campuses; however, these facilities are underused. The study’s objectives were to use the components of the health belief model (HBM) to explore and describe the factors that influenced the decision made by university students who have gone for VCT. The sample consisted of five male students. Data was collected through one-on-one in depth interviews, which were recorded. Data was analysed using thematic analysis, and the components of the HBM were used as codes for the data. Themes were generated for each component. The results indicated that perceived severity, perceived benefits and cues to action played a role in influencing the participants’ decision to go for VCT. In addition, results show that perceived susceptibility had little influence on their decision to go for VCT. Even though participants acknowledged barriers to VCT, they reported that the perceived benefits for VCT outweighed the barriers, and the decision to go for VCT was made. Participants suggested that to increase uptake of VCT on their campus, the university could improve current VCT campaigns, introduce rewards for VCT and introduce couples VCT.

Thesis (DTech (Mechanical Engineering))--Cape Peninsula University of Technology, 2012
In this thesis, we investigate certain key aspects of mathematical modelling to explain the epidemiology of HIV/AIDS at the workplace and to assess the potential benefits of proposed control strategies. Deterministic models to investigate the effects of the transmission dynamics of HIV/AIDS on labour force productivity are formulated. The population is divided into mutually exclusive but exhaustive compartments and a system of differential equations is derived to describe the spread of the epidemic. The qualitative features of their equilibria are analyzed and conditions under which they are stable are provided. Sensitivity analysis of the reproductive number is carried out to determine the relative importance of model parameters to initial disease transmission. Results suggest that optimal control theory in conjunction with standard numerical procedures and cost effective analysis can be used to determine the best intervention strategies to curtail the burden HIV/AIDS is imposing on the human population, in particular to the global economy through infection of the most productive individuals. We utilise Pontryagin’s Maximum Principle to derive and then analyze numerically the conditions for optimal control of the disease with effective use of condoms, enlightenment/educational programs, treatment regime and screening of infectives. We study the potential impact on productivity of combinations of these conventional control measures against HIV. Our numerical results suggest that increased access to antiretroviral therapy (ART) could decrease not only the HIV prevalence but also increase productivity of the infected especially when coupled with prevention, enlightenment and screening efforts.

Abstract:
This descriptive research used the Health Belief Model (HBM) to assess HIV/AIDS knowledge, perceived severity, perceived susceptibility, and behavioral practices within the population throughout the State of Sonsonate, El Salvador. Geographic Information Systems (GIS) was also utilized to display the results of this population study. The study population was composed of 15-39 year olds consisting of a total sample size of 1,500 (250 participants from each of the six cities). The basis of this study was to evaluate where this population fit within the Health Belief Model (HBM) and also to practically represent the results pictorially. Also, this information was collected so that the government of El Salvador could see and understand where their educational deficits existed so that future programs could be established to alleviate these discrepancies. An instrument consisting of 65 items including demographics, knowledge, perceived severity, perceived susceptibility, and behavioral practices was used for the general population. The analysis of the data was two-fold using Geographic Information Systems (GIS) mapping and statistical analysis. GIS mapping was used to graphically pinpoint areas of knowledge deficit and misinformation about HIV/AIDS. Results were based on a general population of 1,454. Various indices were created to show the level of knowledge or frequency of safe behavioral practices. The Perceived Severity and Perceived Susceptibility sections were not aggregated into an index but rather treated as individual variables. An item analysis of the questionnaire found that on average the general population responded correctly to 78% of the knowledge questions. However, a total of 11 questions in the knowledge section had less 75% (n=385) of the general population answering correctly. Another 3 questions in the behavior section were also found to have less than 75% (n=385) indicating safe behavioral practices. Linear regression analyses were performed to explore correlations between the areas of demographics, knowledge level, perceived severity, and perceived susceptibility to safe behavior. GIS maps were created to pictorially show where this population's deficiencies were in regard to the HBM. This research helped to pinpoint where this population fits within the construct of the Health Belief Model so that future educational efforts can be targeted in geographic areas with the greatest need. This will help to move this sample toward behavioral change.

Abstract:
This thesis describes bioanalytical methods for drug determination in biological matrixes, with drugs in focus used against diseases largely affecting low-income countries. Solid-phase extraction is used for sample cleanup, and processed samples are analyzed by liquid chromatography. Developed bioanalytical methods are validated according to international guidelines. Eflornithine (DFMO) is a chiral drug, used for treating human African trypanosomiasis. A bioanalytical method for determination of DFMO enantiomers in plasma is presented. The enantiomers are detected by evaporative light-scattering detection. The method has been applied to determination of D-DFMO and L-DFMO in rats, after intravenous and oral administration of racemic DFMO. It is concluded that DFMO exhibits enantioselective absorption, with the more potent enantiomer L-DFMO being less favored. Sulfadoxine (SD) and sulfamethoxazole (SM) are sulfa-drugs used for malaria and pneumonia respectively. Two methods are described for simultaneous determination of SD and SM in capillary blood sampled on filter paper. The former method allows direct injection of extracts from dried blood spots (DBS), while for the latter method solid-phase extraction is added. Pre-analytical factors contributing to measurement uncertainty is also discussed, and it is concluded that it is of high importance that homogeneity in type of sampling paper and sampling volume is assured. Piperaquine (PQ) is an antimalarial, increasingly used in artemisinin combination therapy. A method for determination of piperaquine in DBS is presented. By using a monolithic LC column, a very short LC analysis of two minutes per sample is achieved. A method for simultaneous determination of three antiretroviral drugs i.e. lamivudine (3TC), zidovudine (AZT) and nevirapine (NVP), in DBS samples is described. The method is applied to drug determination in two subjects after receiving standard antiretroviral treatment. Conclusion is that the method is suitable for determination of 3TC and NVP, and to some extent for AZT.

Abstract:

This study utilised secondary data from a larger study that looked at individuals that are already infected by HIV which is entitled Implicative personal dilemmas and cognitive conflicts in health decision making in HIV positive adults and adults with AIDS. The primary aim of the larger study was to examine the cognitive construction of the individual and how they utilised their individual resources to construct who they are and how they perceived the difficulties and challenges that they face and the decisions they make regarding their health. HIV and AIDS is a debilitating disease and it affects millions worldwide. South Africa, presently, has the largest burden of this disease with those between the ages of 15 &ndash
49 years of age being most affected. As previously 
mentioned the decisions that individuals make can impact on their health. Decisions to take necessary precautions such as protected sex during sexual intercourse can decrease the 
progression of the disease. Decisions made regarding abstinence of risky behaviour as well as being committed to taking medication could also positively impact health. People living with HIV and AIDS find it 
difficult to adjust to the challenges that this disease presents. Depression is often experienced due to the changes in self image and perception. Studies show that 
females are twice more likely to experience depression than men. There has however been no conclusive evidence showing the reason for this, however, the perception of stress based on 
gender could shed some light on this matter and how these perceptions can increase the likelihood of women being more vulnerable to depression. Due to the limitation of this study, it will 
only look at depression as it relates to HIV and AIDS. Psychological problems such as depression can hamper the adjustment process and the effect of depression is evident in that it can lower the CD 4 + cells. Not only are those 
living with HIV and AIDS affected by depression, but they also have a lifetime prevalence to depression. It is important to have an effective screening tool for depression so that the detection of this 
disease can be made and effective treatment can be implemented to enhance health. The sample consisted of 113 adult participants that have already been diagnosed with HIV and AIDS. The 
primary aim of this study was to compare the Beck&rsquo
s Depression Inventory II (BDI II) and the Hospital Anxiety and Depression Scale &ndash
(the Depression component) (HADS-D) as a screening tool 
 
for depression. Exploratory Factor Analysis revealed a 5 factor structure which accounted for 60.14 % of the total variance. The HADS yielded one factor accounting for 14.33% of total variance. The BDI II has proven to be more a reliable measure of depression with 0.89 according to the Cronbach&rsquo
s Alpha co efficient opposed to 0.375 as per the HADS-D. The secondary aim was to establish 
the sociodemographic and disease profiles of the participants under study.

Abstract:
Background: HIV is a virus that attacks the white blood cells (lymphocytes). HIV causing Acquired Immunodeficiency Syndrome (AIDS). HIV/ AIDS has become a global emergency problem. East Java Province is in the top five of the population infected with HIV (8,204) and AIDS (741) and the most dominant are men. This will worsen the situation of women if they are infected pregnant women. This study aimed to analyze the effect of the Health Belief Model approach on the prevention of HIV/ AIDS among pregnant women in Madiun City, East Java. Subjects and Method: This was a cross sectional study conducted in Madiun City, East Java. A total of 80 pregnant women who conducted HIV/ AIDS check was enrolled in this study. The dependent variable was HIV prevention. The independent variables were perceived seriousness, perceived vulnerability, perceived benefit, and perceived barrier. The data were collected using questionnaire and analyzed using multiple logistic regression analysis. Results: There was a positive effect on perceived seriousness (OR = 8.43; 95% CI=1.38 to 51.4; p = 0.021), perceived vulnerability (OR = 8.36; 95% CI=1.06 to 65.9; p = 0.044), perceived benefit (OR = 12.6; 95% CI=1.37 to 115.5; p = 0.025) on the prevention of HIV/ AIDS among pregnant women and it was statistically significant. There was a negative effect on perceived barrier (OR = 0.13; 95% CI=0.02 to 0.86; p = 0.034) and it was statistically significant. Conclusion: Perceived seriousness, perceived vulnerability, perceived benefit, and perceived barrier influence pregnant women in taking HIV/ AIDS prevention.

Abstract:
Background: The HIV-1 envelope glycoprotein (Env) is the target of antigen design for antibody- based vaccination. In 2019, four trimeric Env vaccines entered an experimental trial: ConM, ConS, and their cross-linked counterparts. The trimers were formulated with MPLA adjuvant. Studies have demonstrated that adjuvants trigger neutrophil infiltration. Neutrophils activate and degranulate releasing proteases, namely elastase and cathepsinG. Aims: To assess the stability and immunogenicity of these vaccines in the presence of adjuvant- recruited neutrophils and their proteolytic enzymes. Methods: Trimers were incubated with commercially-sourced proteases. To analyse stability, samples were reduced, denatured and separated using gel electrophoresis. To assess antibody binding, a trimer-protease incubation was followed by an ELISA. To establish more physiologically relevant conditions, harvested neutrophils were exposed to various adjuvants. The supernatant, shown to contain elastase, was incubated alongside the vaccines. The reducing and denaturing gels, as well as the ELISA, was repeated. Results: Gel analysis revealed that un-crosslinked trimers underwent significant digestion whereas cross-linking conferred enhanced stability. In the presence of neutrophil-sourced protease-containing-supernatant, trimers displayed resistance to digestion. The differential stability profile of Env trimers when exposed to commercially sourced compared to supernatant- derived proteases may be due to the inhibitory effect of human serum on elastase. Antibody epitopes were maintained in vitro. Conclusion: The vaccine antigens are sensitive to enzymatic degradation. This is reduced by cross-linking and human serum.
