Feline immunodeficiency virus (FIV) discovered in 1986 is a lentivirus that causes AIDS in domestic cats. FIV is classified into five subtypes (A–E), and all subtypes and circulating intersubtype recombinants have been identified throughout the world. A commercial FIV vaccine, consisting of inactivated subtype-A and –D viruses (Fel-O-Vax FIV, Fort Dodge Animal Health), was released in the United States in 2002. The United States Department of Agriculture approved the commercial release of Fel-O-Vax FIV based on two efficacy trials using 105 laboratory cats and a major safety trial performed on 689 pet cats. The prototype and commercial FIV vaccines had broad prophylactic efficacy against global FIV subtypes and circulating intersubtype recombinants. The mechanisms of cross-subtype efficacy are attributed to FIV-specific T-cell immunity. Findings from these studies are being used to define the prophylactic epitopes needed for an HIV-1 vaccine for humans. PMID:20210778

Inactivated or "killed" virus (KV) is a "classical" approach that has produced safe and effective human and veterinary vaccines but has received relatively little attention in the effort to develop an HIV/AIDS vaccine. Initially, KV and rgp120 subunit vaccines were the two most obvious approaches but, unfortunately, rgp120 has not been efficacious and the KV approach has been limited by a variety of scientific, technical, and sociological factors. For example, when responses to cellular antigens, present on SIV grown in human cells, proved to be largely responsible for efficacy, the KV approach was widely discounted. Similarly, when lab-adapted HIV-1 appeared to lose envelope glycoprotein during preparation (not the case for primary isolates), this was viewed as a fundamental barrier to the KV concept. Also, a preference for "safer", genetically-engineered vaccines, and emphasis on cellular immunity, have left KV low on the priority list for funding agencies and investigators. The recent suggestion that "native" trimeric gp120 displays conserved conformational neutralization epitopes, along with the failure of rgp120, and difficulties in raising strong cellular responses with DNA or vectored vaccines, has restored some interest in the KV concept. In the past 15 years, several groups have initiated pre-clinical development of KV candidates for SIV or HIV and promising, albeit limited, information has been produced. In this chapter we discuss the rationale (including pros and cons) for producing and testing killed-HIV vaccines, the prospects for success, the nature and scope of research needed to test the KV concept, what has been learned to date, and what remains undone.

HIV/AIDS continues to be a significant public health problem. Millions of people worldwide are infected with this virus daily, and thousands die yearly of AIDS-related illnesses. Despite rapid advances in our knowledge about HIV and its mode of transmission, we have been unable to find a cure or prevent new infections. Psychiatric comorbidity is associated with HIV/AIDS: as a risk factor for HIV infection, a comorbidity of HIV infection, sequelae of HIV/AIDS, and a potential mediator for progression to AIDS. In this article, we focus on depression, which is prevalent in HIV/AIDS. We review the evidence associating depression with HIV, the challenges in recognizing depression in HIV-positive individuals, and the psychopharmacologic strategies known to be effective in the treatment of HIV-positive individuals with depression.

Antibody to hepatitis E virus of IgG class (anti-HEV IgG) is regularly detected in industrialized countries, where HEV is non-endemic, at levels not exceeding 2-3%; seropositive individuals are often found in certain groups of patients and professionals exposed to an increased risk of blood-borne infections. The present study was aimed at the identification of anti-HEV IgG in patients with human immunodeficiency virus (HIV) infection, including acquired immune deficiency syndrome (AIDS), living in Russia and Belarus, an area of low anti-HEV prevalence with a moderate spread of HIV infection and AIDS. In Russia, 13 out of 117 HIV-infected patients (11.1%) were found to be anti-HEV seropositive. This differed significantly from the frequency observed in the normal population (1.7%) but not from the frequency in a matching control, high-risk group consisting of male prisoners (8.0%). No difference in the frequency of anti-HEV IgG seropositivity was found between groups of HIV-infected men subdivided by sexual orientation. The rate of anti-HEV seropositivity increased with the progression of HIV infection, reaching 43.3% in AIDS patients and 38.1% in those who died from AIDS. In Belarus, anti-HEV IgG seropositivity was not found among 20 HIV-infected subjects nor among individuals from the control risk group, which consisted of 25 intravenous drug users. In conclusion, HEV infection may have common transmission mechanisms (risk factors) with HIV infection rather than represent an additional opportunistic infection in AIDS.

Antiretroviral therapy can inhibit HIV replication in patients and prevent progression to AIDS. However, it is not curative. Here we provide an overview of what antiretroviral drugs do and how the virus persists during therapy in rare reservoirs, such as latently infected CD4+ T cells. We also outline several innovative methods that are currently under development to eradicate HIV from infected individuals. These strategies include gene therapy approaches intended to create an HIV-resistant immune system, and activation/elimination approaches directed towards flushing out latent virus. This latter approach could involve the use of novel chemically synthesized analogs of natural activating agents.

Acquired Immunodeficiency Syndrome (AIDS) is the final and most serious stage of the disease caused by human immunodeficiency virus. The Immune system is the target of AIDS. We investigate presently any possible involvement of thyroid hormone, the deficiency of which gives rise to oedema and susceptibility to nonspecific infections; with a view to finding the primary factor seeding the disease. It has been reported that circumcision reduced the incidence of HIV/AIDS infection. Beyond circumcision however there might be some constitutional factor that comprises HIV infection to clinical AIDS. It is against this background that our research team turned to possible dyshormonopoisis and to thyroid hormone as a prime suspect among other possible factors that cause clinical AIDS. Moreover the hormone has been reported to be crucial for optimum immune function. A population of 200 seropositive AIDS patients were investigated against a control of 50 subjects made up of 25 healthy circumcised males and 25 healthy females; all of who were seronegative for the disease. The parameters investigated include thyrotropin (TSH), Thyroxine (T4), Total protein (TP), Albumin (Alb), Globulin (Glob), Immune complex (IC3) and Bence Jones proteins (BJP) levels in serum or urine. All seropositive clinically HIV/AIDS patients were hypothyroid. Seronegatives had significantly higher T4, TP, and Alb levels at P < 0.001 and P < 0.05 for Glob than seropositives. Seropositive females exhibited significant (P < 0.001) higher levels of IC3 than seronegative males. The globulin levels of all HIV patients were significantly (P < 0.05) higher than control. BJP was also isolated in the urine of patients. The findings suggest that thyroid hormone deficiency is a primary culprit for the other inert or dormant factors to be activated.

We consider a simple HIV/AIDs finite dimensional mathematical model on interactions of the blood cells, the HIV/AIDs virus and the immune system for consistence of the equations to the real biomedical situation that they model. A better understanding to a cure solution to the illness modeled by the finite dimensional equations is given. This is accomplished through rigorous mathematical analysis and is reinforced by numerical analysis of models developed for real life cases.

Since September 1984, six cases of acquired immune deficiency syndrome (AIDS) and 11 cases of AIDS related complex (ARC) have been reported in Thailand. All people with AIDS were homosexual or bisexual men; two were Thai and the rest were European or American. Nine of the 11 people with ARC were homosexual or bisexual men, one was the female sexual partner of a man with AIDS, and one was a Thai man who had lived in the United States of America for several years, but denied having had any homosexual contact. Nine of the 11 people with ARC were Thai. In a survey in April 1985 at a resort area near Bangkok, antibodies to human immunodeficiency virus (HIV) (confirmed by western blot) were detected in 2.4% of 127 homosexual men and none of 77 female prostitutes. In a more extensive survey in October 1985, antibodies were detected in 0.8% of 720 homosexual men, but none of 2880 female prostitutes or 309 sexually active heterosexual men. HIV has been introduced into Thailand primarily by homosexual transmission. The public health policy of Thailand concerning AIDS is discussed.

Objective: This study aimed to determine whether the human immunodeficiency virus (HIV) exists in giant idiopathic esophageal ulcers in the patients with acquired immune deficiency syndrome (AIDS). Methods: 16 AIDS patients with a primary complaint of epigastric discomfort were examined by gastroscopy. Multiple and giant esophageal ulcers were biopsied and analyzed with pathology staining and reverse transcription-polymerase chain reaction (RT-PCR) to determine the potential pathogenic microorganisms, including HIV, cytomegalovirus (CMV) and herpes simplex viruses (HSV). Results: HIV was detected in ulcer samples from 12 out of these 16 patients. Ulcers in 2 patients were infected with CMV and ulcers in another 2 patients were found HSV positive. No obvious cancerous pathological changes were found in these multiple giant esophageal ulcer specimens. Conclusion: HIV may be one of the major causative agents of multiple benign giant esophageal ulcers in AIDS patients. PMID:27830031

Many of the clinical features of HIV/AIDS can be ascribed to the profound immune deficiency which develops in infected patients. The destruction of the immune system by the virus results in opportunistic infection, as well as an increased risk of autoimmune disease and malignancy. In addition, disease manifestations related to the virus itself may occur. For example, during the primary illness which occurs within weeks after first exposure to HIV, clinical symptoms occur in at least 50% of cases, typically as a mononucleosis syndrome. HIV-related complications are rarely encountered in patients with preserved immunity (i.e. CD4 T-cell counts greater than 500 cells/mm3). Recurrent mucocutaneous herpes simplex (HSV), herpes zoster (VZV), oral candidiasis and oral hairy leukoplakia occur with increasing frequency as the CD4 count drops below this level. Immune thrombocytopenia (ITP) occurs in association with HIV and often presents early in the clinical course. The risk of developing opportunistic infections and malignancies typical of AIDS increases progressively as CD4 counts fall below 200 cells/mm3. The clinical manifestations of infections associated with AIDS tend to fall into well-recognized patterns of presentation, including pneumonia, dysphagia/odynophagia, diarrhoea, neurological symptoms, fever, wasting, anaemia and visual loss. The commonest pathogens include Candida albicans, Pneumocystis carinii, Mycobacterium tuberculosis, Toxoplasma gondii, Cryptococcus neoformans, Mycobacterium avium intracellulare and cytomegalovirus. Malignant disease in patients with HIV infection also occurs in a characteristic pattern. Only two tumours are prevalent: Kaposi's sarcoma, a multifocal tumour of vascular endothelium which typically involves skin and mucosal surfaces; and non-Hodgkin's lymphoma, which is typically high grade in phenotype, often arising within the central nervous system. The principles of therapy include reduction of HIV replication by antiretroviral

Nearly 34 million people are currently living with HIV/AIDS: ocular complications are common, affecting 50% to 75% of all such patients at some point during the course of their illness. Cytomegalovirus retinitis is by far the most frequent cause of vision loss in patients with AIDS. Although the prevalence of cytomegalovirus retinitis is decreasing in industrialized countries because of the widespread availability of highly active antiretroviral therapy, between 10% and 20% of HIV-infected patients worldwide can be expected to lose vision in one or both eyes as a result of ocular cytomegalovirus infection. Less frequent but important causes of bilateral vision loss in patients with HIV/AIDS include varicella zoster virus and herpes simplex virus retinitis, HIV-related ischaemic microvasculopathy, ocular syphilis, ocular tuberculosis, cryptococcal meningitis, and ocular toxic or allergic drug reactions. At present, most patients with HIV/AIDS in developing countries who lose their vision have a very limited life expectancy. As antiretroviral therapy makes its way to these countries, however, both life expectancy and the prevalence of blindness related to HIV/AIDS can be expected to increase dramatically. PMID:11285664

Since it tends to be significantly affected by HIV/AIDS, the tourism sector is a likely target for HIV/AIDS interventions in many countries. The tourist industry is at particular risk from the pandemic because of the mobility of the work force, the presence of sex tourists, and the heavy reliance of many countries upon tourism revenues. Indeed, tourism is one of the largest and fastest growing industries in many countries. Some people have speculated that potential tourists' fear of AIDS could discourage them from visiting certain countries, while others have even suggested that tourism should be discouraged because the industry contributes to the spread of HIV/AIDS. When traveling, tourists often take risks that they would not take at home. They tend to drink more, use drugs more, and be generally more adventurous while on holiday. Such adventures often include taking sexual risks. When tourists have sex with prostitutes, hotel staff, and others in the local population, a bridge can be created for HIV to cross back and forth between the tourist's home country and the tourist destination. The author reviews selected studies on the relationship between HIV/AIDS and tourism. Overall, the existing literature offers no definitive evidence that AIDS has had any lasting impact upon the tourism industry anywhere in the world. Rather, promoting a healthy tourism industry and HIV/AIDS prevention are likely complementary in many ways.

Exosomes are membranous extracellular nanovesicles secreted by diverse cell types. Exosomes from healthy human semen have been shown to inhibit HIV-1 replication and to impair progeny virus infectivity. In this study, we examined the ability of healthy human semen exosomes to restrict HIV-1 and LP-BM5 murine AIDS virus transmission in three different model systems. We show that vaginal cells internalize exosomes with concomitant transfer of functional mRNA. Semen exosomes blocked the spread of HIV-1 from vaginal epithelial cells to target cells in our cell-to-cell infection model and suppressed transmission of HIV-1 across the vaginal epithelial barrier in our trans-well model. Our in vivo model shows that human semen exosomes restrict intravaginal transmission and propagation of murine AIDS virus. Our study highlights an antiretroviral role for semen exosomes that may be harnessed for the development of novel therapeutic strategies to combat HIV-1 transmission. PMID:25880110

Up to December 1993, a total of 10858 AIDS cases were reported to the central AIDS registry at the Federal Health Office. Human immunodeficiency virus is acquired through needle sharing (i.v. drug users), contaminated blood transfusions, intercourse with infected persons and transplacentally by fetuses. In Germany, about seven people a day are estimated to acquire the HIV infection. Half the patients will develop systemic manifestations of AIDS within 12-13 years. Only a small percentage of these patients suffer from urological manifestations, e.g. urinary tract infection, prostatism or HIV-associated nephropathy. Nevertheless, knowledge of genitourinary pathology caused by HIV makes early diagnosis of AIDS possible.

Human immunodeficiency virus and the acquired immunodeficiency syndrome (HIV/AIDS) have greatly complicated dermatologic disease and the required care in most regions of Africa. Opportunistic infections, ectoparasites, Kaposi sarcoma, and skin manifestations of systemic infections are exceedingly common in patients with HIV/AIDS. Dermatologists have contributed significantly to our knowledge base about HIV/AIDS and have played an important educational role regarding the clinical manifestations historically. Because of the increased burden of skin disease in Africa due to the HIV/AIDS epidemic we must redouble our efforts to provide dermatology education to care providers in Africa. We review the burden of skin disease in Africa, how it relates to HIV/AIDS and global infectious disease, current educational strategies in Africa to address this need, and suggest potential solutions to move these efforts forward. PMID:21887061
Although epigenetics is not a new field, its implications for acquired immunodeficiency syndrome (AIDS) research have not been explored fully. To develop therapeutic and preventive approaches against the human immunodeficiency virus (HIV) and AIDS, it is essential to understand the mechanisms of interaction between the virus and the host, involvement of genetic and epigenetic mechanisms, characterization of viral reservoirs, and factors influencing the latency of the virus. Both methylation of viral genes and histone modifications contribute to initiating and maintaining latency and, depending on the context, triggering viral gene repression or expression. This chapter discusses progress made at the National Institutes of Health (NIH), recommendations from the International AIDS Society Scientific Working Group on HIV Cure, and underlying epigenetic regulation. A number of epigenetic inhibitors have shown potential in treating AIDS-related malignancies. Epigenetic drugs approved by the US Food and Drug Administration and their implications for the eradication of HIV/AIDS and AIDS-related malignancies also are discussed.Past and current progress in developing treatments and understanding the molecular mechanisms of AIDS and HIV infection has greatly improved patient survival. However, increased survival has been coupled with the development of cancer at higher rates than those observed among the HIV/AIDS-negative population. During the early days of the AIDS epidemic, the most frequent AIDS-defining malignancies were Kaposi's sarcoma and non-Hodgkin lymphoma (NHL). Now, with increased survival as the result of widespread use in the developed world of highly active antiretroviral therapy (HAART), non-AIDS defining cancers (i.e., anal, skin, and lung cancers, and Hodgkin disease) are on the increase in HIV-infected populations. The current status of AIDS-related malignancies also is discussed.

This paper outlines some of the imperatives that should drive attention to the rights of legal and illegal migrants to health, particularly in relation to HIV/AIDS. It is noted that migrants can be especially vulnerable to HIV/AIDS/sexually transmitted diseases (STDs), but they are often excluded or simply missed in many prevention and care programs. In terms of the effects of globalization, it would seem that governments are required to ensure that this state of affairs does not continue. Evidence indicates that human rights and other ethical violations are occurring and need to be urgently addressed at local, national and international levels. In view of such, it is recommended that HIV/AIDS/STD prevention and care programs for migrant populations should be developed with and guided by migrant communities, and involving substantial community mobilization. Although some progress in preventing the spread of HIV to and from migrants have been documented, and projects addressing their needs have been made accessible, the challenge of dealing more comprehensively the complex issues involved still remains.

Background Studies show that nearly 40 million people are living with human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) around the world and since the beginning of the epidemic, about 35 million have died from AIDS. Heterosexual intercourse is the most common route for transmission of HIV infection (85%). People with a sexually transmitted infection (STI), such as syphilis, genital herpes, chancroid, or bacterial vaginosis, are more likely to obtain HIV infection during sex. On the other hand, a patient with HIV can acquire other infections such as hepatitis C virus (HCV) and hepatitis B virus (HBV) and also STIs. Co-infections and co-morbidities can affect the treatment route of patients with HIV/AIDs. Sometimes, physicians should treat these infections before treating the HIV infection. Therefore, it is important to identify co-infection or comorbidity in patients with HIV/AIDS. Objectives This study was conducted in order to understand the prevalence of HIV/AIDS/STI co-infection. Patients and Methods In this cross-sectional study, we evaluated all HIV/AIDS patients who were admitted to the infectious wards of Boo-Ali hospital (Southeastern Iran) between March 2000 and January 2015. All HIV/AIDS patients were studied for sexually transmitted infections (STI) such as syphilis, gonorrhea, hepatitis B virus (HBV) and genital herpes. A questionnaire including data on age, sex, job, history of vaccination against HBV, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc), hepatitis B surface antigen (anti-HBs), HCV-Ab, venereal disease research laboratory (VDRL) test, fluorescent treponemal antibody absorption (FTA-Abs) test, and urine culture was designed. Data was analyzed by the Chi square test and P values of < 0.05 were considered significant. Results Among the 41 patients with HIV/AIDS (11 females and 30 males; with age range of 18 to 69 years) five cases (12.1%) had a positive test (1:8 or more) for
We explore the links between substance use, misuse, addiction, and dependency1 and sexuality, sexually transmitted diseases (STD), human immunodeficiency virus (HIV), and acquired immune deficiency syndrome (AIDS) to increase our awareness of their interdependence and to identify new ways to perceive, judge, and intervene (or not to) with associated problems. We consider the sociocultural and economic context in which these behaviors occur; the impact these behaviors have on one another; the personal opinions and attitudes; the religious, moral, or political beliefs and agendas; the physiological and fiscal constraints; and theories of rational decision-making and psychological motivation that act to increase or reduce the incidence of these behaviors and their sequellae, while hindering or facilitating prevention, harm reduction, and treatment interventions. Mechanisms of epidemic spread of STDS/HIV/AIDS are presented in the Appendix. Each of these terms are loaded "container concepts" that are culture-bound and stakeholder-driven and whose dimensions are less than consensus-based. They represent a range of meanings, uses, and misuses in an ongoing politicalized area of human and systemic functioning and adaptations.

Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) are leading chronic illnesses in many major cities worldwide. Frequently, people with HIV infection require surgery or develop chronic wounds. This paper summarizes the impact of HIV infection on body organs and systems and the effect of antiretroviral therapy as a basis for potential complications with wound care and healing. The authors also present research on wound healing in HIV-positive people undergoing operative procedures. Besides the physical effect of HIV infection on the person, clinicians must also realize psychosocial and economic effects of the disease when considering wound care. This paper also addresses care considerations for patients with HIV/AIDS in the inpatient, outpatient, and home care settings.

Acquired immunodeficiency syndrome (AIDS) of humans is caused by two lentiviruses, human immunodeficiency viruses types 1 and 2 (HIV-1 and HIV-2). Here, we describe the origins and evolution of these viruses, and the circumstances that led to the AIDS pandemic. Both HIVs are the result of multiple cross-species transmissions of simian immunodeficiency viruses (SIVs) naturally infecting African primates. Most of these transfers resulted in viruses that spread in humans to only a limited extent. However, one transmission event, involving SIVcpz from chimpanzees in southeastern Cameroon, gave rise to HIV-1 group M-the principal cause of the AIDS pandemic. We discuss how host restriction factors have shaped the emergence of new SIV zoonoses by imposing adaptive hurdles to cross-species transmission and/or secondary spread. We also show that AIDS has likely afflicted chimpanzees long before the emergence of HIV. Tracing the genetic changes that occurred as SIVs crossed from monkeys to apes and from apes to humans provides a new framework to examine the requirements of successful host switches and to gauge future zoonotic risk.

Cross-reactive immunity occurs when infection with or vaccination against one virus protects against another related family member. A search for homologues of the HIV-1 envelope glycoprotein revealed that it is composed of thousands of intercalating and overlapping viral matches of pentapeptide or longer gapped consensi, belonging to over 70% of the currently sequenced virome, infecting all kingdoms from bacteria to man. It was also highly homologous to proteins from the Visna/Maedi and other ovine viruses, while other proteins (nef/tat/gag/pol) were homologous to proteins from the equine infectious anaemia virus and HTLV-2/HTLV-3 viruses. This phenomenon suggests that horizontal gene transfer from coinfecting RNA and DNA viruses to retroviruses is extensive, providing a route for the subsequent insertion of non-retroviral genes into human and other genomes via retroviral integration. This homology includes all viruses for which vaccines already exist. Cross-reactive immunity may be operative in AIDS, as Vaccinia vaccination decreases viral replication in HIV-1 infected patients' cells, for the CCR5 tropic form. Measles, Dengue virus, or GB virus C infections also decrease the HIV-1 viral load. A resumption of Vaccinia/smallpox vaccination might be expected to have a significant effect on the AIDS pandemic, and a careful study of the potential uses of other existing viral and bacterial vaccines merits close attention. This phenomenon may also be relevant to other recalcitrant viruses, bacteria, and parasites for which no vaccine exists and the armory of existing vaccines may have a role to play in diseases other than those for which they were designed.

Women account for half of the global human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) infections. Heterosexual contact is the leading risk factor in women. Over 50% of patients are significantly immunosuppressed at the time of diagnosis. Women with advanced HIV infection are at a risk for opportunistic infections (OIs). OIs lead to significant morbidity and cost. Some of OIs may impact women more significantly than men, that is, human papillomavirus infection and cervical cancer. OIs during pregnancy can increase the risk of maternal-to-child transmission of HIV and some OIs, such as Hepatitis C. This chapter will review of OIs that are most important in women's health.

The greatest current threat to humanity, most especially in the developing countries of the world, is HIV/AIDS. The first case of HIV/AIDS in Nigeria was in 1986 in Lagos. Due to inaction and denial by the people, there was a rapid but subtle transmission of the virus within Nigeria's various populations and communities. Presently, the disease has…

In the 1990s, defenders of "aids exceptionnalism" have promised that the inequities caused by HIV/AIDS could provide leverage in the care of other health issues later. Fifteen years later, this argument can be rethought at the light of the current context of hepatitis B virus (HBV) in Ivory Coast. In fact, in this country, the challenges caused by HBVecho those of HIV/AIDS fifteen years ago: high prevalence (8-10%), ignorance of the disease, and high cost of care. To this end, this article compares the role of private companies in the fights against HIV/AIDS in the 2000s and its role in the fight against HBV today. Although some private firms played a critical role in the promotion of universal access to ART, today, they are one of the few places where HBV screening, vaccination and treatment are offered in the country. HIV/AIDS opened the door for private companies to address other diseases through their health care systems. However, many challenges still need to be met: the absence of qualitative ongoing training for health professionals, illness representations and the costs of treatments, which are all related to the lack of international and national collective action. In Ivory Coast, at the early stage of the HIV/AIDS epidemic, national authorities took up the leadership in the fight against AIDS in West Africa, by developing extraverted strategies (Xth ICASA's organization, Unaids initiative hosting). The exceptional international mobilization and the creation of innovative funding mechanisms [International Therapeutic Solidarity Fund (ITSF), Global Fund (GM), and President's Emergency Plan for AIDS Relief (PEPFAR)] have facilitated easy access to ARV. Although 380 million people are infected by chronic HBV in the world, even so, international and national collective actions are fledgling and remained weak. Moreover, private firms have represented leverage for testing, treatment, and the provision of universal access to medication in the context of the HIV/AIDS

HIV/AIDS is increasing in prevalence in China and spread of infection from highly risk populations to the general populations was recognized. Despite the fact, there are still only few scientific reviews on quality of life (QOL) for people living with HIV/AIDS (PLWHAs). However, many PLWHAs are struggling with social and psychological influences such as substances abuse, cultural beliefs, depression, stigma, poverty, which can affect their QOL. Public unawareness about infection and disease, willingness to seek medical care and motivation to follow therapy are indirectly influencing health outcome. In 2003 Chinese government has established the so-called the "Four Frees and One Care" policy. The policy was officially implemented from 2004 in some areas, yet to date it is not implemented nationwide. This paper discussed the epidemiology of HIV, underlying psychosocial factors affecting PLWHAs and their impact on QOL. We put forward some recommendations for stakeholders, advocacy groups, non-government organizations and Chinese government.

Human Immunodeficiency Virus (HIV) infection causes progressive damage to both limbs of the immune system, which results in a plethora of opportunistic infections. Among the various opportunistic infections, gastrointestinal infections are very common in HIV / Acquired Immunodeficiency Syndrome (AIDS). Opportunistic spore-forming protozoal parasites, namely, Cryptosporidium parvum, Isospora belli, Cyclospora cayetanensis, and Microsporidia, play a major role in causing chronic diarrhea, accompanied with weight loss, in patients with HIV / AIDS. The purpose of this review is to discuss the salient microbiological, clinical, and diagnostic aspects of important enteric spore-forming opportunistic parasites in HIV / AIDS.
Efficacy of zidovudine and human immunodeficiency virus (HIV) hyperimmune immunoglobulin for reducing perinatal HIV transmission from HIV-infected women with advanced disease: results of Pediatric AIDS Clinical Trials Group protocol 185.
Stiehm, E R; Lambert, J S; Mofenson, L M; Bethel, J; Whitehouse, J; Nugent, R; Moye, J; Glenn Fowler, M; Mathieson, B J; Reichelderfer, P; Nemo, G J; Korelitz, J; Meyer, W A; Sapan, C V; Jimenez, E; Gandia, J; Scott, G; O'Sullivan, M J; Kovacs, A; Stek, A; Shearer, W T; Hammill, H
Pediatric AIDS Clinical Trials Group protocol 185 evaluated whether zidovudine combined with human immunodeficiency virus (HIV) hyperimmune immunoglobulin (HIVIG) infusions administered monthly during pregnancy and to the neonate at birth would significantly lower perinatal HIV transmission compared with treatment with zidovudine and intravenous immunoglobulin (IVIG) without HIV antibody. Subjects had baseline CD4 cell counts =500/microL (22% had counts <200/microL) and required zidovudine for maternal health (24% received zidovudine before pregnancy). Transmission was associated with lower maternal baseline CD4 cell count (odds ratio, 1.58 per 100-cell decrement; P=.005; 10.0% vs. 3.6% transmission for count <200 vs. >/=200/microL) but not with time of zidovudine initiation (5.6% vs. 4.8% if started before vs. during pregnancy; P=. 75). The Kaplan-Meier transmission rate for HIVIG recipients was 4. 1% (95% confidence interval, 1.5%-6.7%) and for IVIG recipients was 6.0% (2.8%-9.1%) (P=.36). The unexpectedly low transmission confirmed that zidovudine prophylaxis is highly effective, even for women with advanced HIV disease and prior zidovudine therapy, although it limited the study's ability to address whether passive immunization diminishes perinatal transmission.

Infection with the human immunodeficiency virus (HIV) that causes acquired immunodeficiency syndrome (AIDS) is still rising globally. In order to develop effective HIV/AIDS risky behavior reduction intervention strategies and to further decrease the spread of HIV/AIDS, it is important to assess the prevalence of psychosocial problems and HIV/AIDS risky behaviors in people living with HIV/AIDS (PLWHA). The objective of this study is to assess the relationship between psychosocial variables and HIV/AIDS risky behaviors among PLWHA. A total of 341 questionnaires were distributed and 326 were fully completed and returned, 96% response rate. The relationships between the identified psychosocial and HIV/AIDS risky behaviors among PLWHA were analyzed using The Moment Structures software version 17.0 (SPSS Inc.) The results indicate that psychosocial health problems were significant predictors of HIV/AIDS risky behaviors in PLWA. Further cross-disciplinary research that addresses the manner in which psychosocial problems and HIV/AIDS risky behaviors interact with each other among PLWHA is needed. PMID:22374351

The fight against HIV/AIDS poses enormous challenges worldwide, generating fears that success may be too difficult or even impossible to attain. Uganda has demonstrated that an early, consistent and multisectoral control strategy can reduce both the prevalence and the incidence of HIV infection. From only two AIDS cases in 1982, the epidemic in Uganda grew to a cumulative 2 million HIV infections by the end of 2000. The AIDS Control Programme established in 1987 in the Ministry of Health mounted a national response that expanded over time to reach other relevant sectors under the coordinating role of the Uganda AIDS Commission. The national response was to bring in new policies, expanded partnerships, increased institutional capacity for care and research, public health education for behaviour change, strengthened sexually transmitted disease (STD) management, improved blood transfusion services, care and support services for persons with HIV/AIDS, and a surveillance system to monitor the epidemic. After a decade of fighting on these fronts, Uganda became, in October 1996, the first African nation to report declining trends in HIV infection. Further decline in prevalence has since been noted. The Medical Research Council (UK) and the Uganda Virus Research Institute have demonstrated declining HIV incidence rates in the general population in the Kyamulibwa in Masaka Districts. Repeat knowledge, attitudes, behaviour and practice studies have shown positive changes in the priority prevention indicators. The data suggest that a comprehensive national response supported by strong political commitment may be responsible for the observed decline. Other countries in sub-Saharan Africa can achieve similar results by these means. Since success is possible, anything less is unacceptable. PMID:11799443

A retrospective review of 4,721 human immunodeficiency virus (HIV)-infected patients, followed at St. Luke's Roosevelt Hospital Center, New York City, was conducted from January 1, 2005 to December 31, 2009. HIV-Hepatitis B virus (HBV) co-infection rate was 218/4,721, 4.6%. Among co-infected patients, 19 patients (19/218, 8.7%) died; 13 patients (13/19, 68.4%) died from non-acquired immune deficiency syndrome (AIDS) defining including 2 patients with liver failure. More non-survivors (5 patients, 5/19, 26.3%) had liver cirrhosis than those who survived (8 patients, 8/199, 4.0%; P = 0.002). There were more patients with positive HBV e antigen (HBeAg) among non-survivors, (12 patients, 12/19, 63.2%) than among survivors (74 patients, 74/199, 37.2%; P = 0.047). HIV-HBV co-infection is associated with increased overall mortality. Therefore, use of dual active antiretrovirals, particularly, tenofovir (TDF) based regimen for optimal suppression of HIV-HBV and immune restoration with prevention of high risk behaviors may contribute to improved outcomes.

According to a 2004 report by the Joint United Nations Programme on HIV/AIDS, Chile has an incipient HIV/AIDS epidemic. Regardless of the classification, every year the cumulative incidence of HIV/AIDS increases. Young Chileans have been the most affected group; still, their knowledge, attitudes, and concerns about HIV/AIDS are not known. This study describes Chilean university students' HIV/AIDS-related knowledge, their worry about getting the virus, and the correlation between both variables. A convenience sample of 45 university students responded to an anonymous self-administered questionnaire after orally consenting to participate in this study. Overall, students had good levels of HIV/AIDS-related knowledge, with 77% responding correctly to at least 85% of the questions. Despite this knowledge, almost 56% of students stated that they were not worried about getting HIV/AIDS. The situation was corroborated by a nonsignificant statistical correlation between both variables (p > .05). These results are congruent with literature from other countries and strengthen the need for further research to clarify why university students, the majority of whom are well-educated and engage in behaviors that place them at risk for contracting the virus, do not worry about HIV.

Recent studies have highlighted the importance of eradication of human immunodeficiency virus (HIV) and cure of acquired immunodeficiency syndrome (AIDS). However, a pivotal point that the patient immunity controls HIV reactivation after highly active anti-retroviral therapy [HAART or combination anti-retroviral therapy (cART)] remains less well addressed. In spite of the fact that both innate and adaptive immunities are indispensable and numerous cells participate in the anti-HIV immunity, memory CD4 T-cells are indisputably the key cells organizing all immune actions against HIV while being the targets of HIV. Here we present a view and multidisciplinary approaches to HIV/AIDS eradication and cure. We aim at memory CD4 T-cells, utilizing the stem cell properties of these cells to reprogram an anti-HIV memory repertoire to eliminate the viral reservoir, toward achieving an AIDS-free world.

Human immunodeficiency virus (HIV) spread to humans from chimpanzees (HIV-1 groups M and N), gorillas (HIV-1 groups P and O), and sooty mangabeys (HIV-2). HIV is spread mainly through blood or body fluids. Subjects can become infected with HIV by sexual contact, needle sharing, blood transfusions, or maternal transmissions as a blood-borne virus or via breast-milk. The incubation period of HIV-1 from infection to the development of AIDS ranges from 8 to 11 years. In the past 3 decades, HIV has caused a great burden to global wealth and health. According to the WHO global health survey, 36.7 million people were infected with HIV, causing 1.1 million deaths in 2015. Since the discovery of HIV-1, many anti-retroviral drugs have been developed. Following the discovery and wide-spread use of anti-retroviral therapy (ART) the life expectancy of HIV infected individuals has substantially increased. By 2015, all major guidelines recommended treating all HIV-infected adults regardless of their CD4 count. Despite effective ART with virological suppression, HIV-associated neurocognitive disorders (HAND), cardiovascular diseases (CVD), metabolic syndrome (MS), bone abnormalities and non-HIV-associated malignancies remain a major complication associated with HIV infection. In this review article, I would like to describe recent ART status and problems in the ART-era.

More than 40 million people worldwide have been infected with human immunodeficiency virus (HIV) since it was first reported in 1981. Over 25 million of these have lost their lives to the disease. Most of the studies related to HIV/AIDS have been conducted in stable populations across the globe. Few of these studies have been devoted to displaced populations, particularly those in areas of conflict. Displaced populations that are forced to leave their homes in most cases find themselves in unfamiliar territories, often poor and hungry. Many of them become refugees and internally displaced people (IDPs). The objective of this review was to address a number of different social determinants of HIV/AIDS in displaced populations in areas of conflict. A comprehensive review of peer reviewed literature published in English between 1990 and 2010 obtained through an open search of PUBMED database using key words such as HIV and war, HIV/AIDS and conflict, AIDS and security was conducted. Twelve different studies that looked at the implications of HIV/AIDS in conflict or displaced populations were retrieved. The review revealed that there were various factors influencing conflict and HIV/AIDS such as forced population displacement, breakdown of traditional sexual norms, lack of health infrastructure, and poverty and powerlessness of women and children. Social determinants of increased HIV/AIDS prevalence in displaced populations are scarcity of food, poverty, insecurity of displaced populations and gender power differentials. PMID:28299050

This special report discusses the impact of globalization, patterns of migration in Southeast Asia, gender issues in migration, the links between migration and HIV/AIDS, and spatial mobility and social networks. Migrants are particularly marginalized in countries that blame migrants for transmission of infectious and communicable diseases and other social ills. Effective control of HIV/AIDS among migrant and native populations requires a multisectoral approach. Programs should critically review the privatization of health care services and challenge economic models that polarize the rich and the poor, men and women, North and South, and migrant and native. Programs should recognize the equality between locals and migrants in receipt of health services. Countermeasures should have input from migrants in order to reduce the conditions that increase vulnerability to HIV/AIDS. Gender-oriented research is needed to understand women's role in migration. Rapid assessment has obscured the human dimension of migrants' vulnerability to HIV. Condom promotion is not enough. Migration is a major consequence of globalization, which holds the promise, real or imagined, of prosperity for all. Mass migration can be fueled by explosive regional developments. In Southeast Asia, migration has been part of the process of economic development. The potential to emigrate increases with greater per capita income. "Tiger" economies have been labor importers. Safe sex is not practiced in many Asian countries because risk is not taken seriously. Migrants tend to be used as economic tools, without consideration of social adjustment and sex behavior among singles.

The vaccinia virus (VACV) C6 protein has sequence similarities with the poxvirus family Pox_A46, involved in regulation of host immune responses, but its role is unknown. Here, we have characterized the C6 protein and its effects in virus replication, innate immune sensing and immunogenicity in vivo. C6 is a 18.2 kDa protein, which is expressed early during virus infection and localizes to the cytoplasm of infected cells. Deletion of the C6L gene from the poxvirus vector MVA-B expressing HIV-1 Env, Gag, Pol and Nef antigens from clade B (MVA-B ΔC6L) had no effect on virus growth kinetics; therefore C6 protein is not essential for virus replication. The innate immune signals elicited by MVA-B ΔC6L in human macrophages and monocyte-derived dendritic cells (moDCs) are characterized by the up-regulation of the expression of IFN-β and IFN-α/β-inducible genes. In a DNA prime/MVA boost immunization protocol in mice, flow cytometry analysis revealed that MVA-B ΔC6L enhanced the magnitude and polyfunctionality of the HIV-1-specific CD4+ and CD8+ T-cell memory immune responses, with most of the HIV-1 responses mediated by the CD8+ T-cell compartment with an effector phenotype. Significantly, while MVA-B induced preferentially Env- and Gag-specific CD8+ T-cell responses, MVA-B ΔC6L induced more Gag-Pol-Nef-specific CD8+ T-cell responses. Furthermore, MVA-B ΔC6L enhanced the levels of antibodies against Env in comparison with MVA-B. These findings revealed that C6 can be considered as an immunomodulator and that deleting C6L gene in MVA-B confers an immunological benefit by enhancing IFN-β-dependent responses and increasing the magnitude and quality of the T-cell memory immune responses to HIV-1 antigens. Our observations are relevant for the improvement of MVA vectors as HIV-1 vaccines.

Antiretroviral therapy advances have proportioned to AIDS patients a survival increase. At the same time, the permanence of the seropositive people in the nosocomial environment becomes common not only by the adverse reactions caused by this therapy, but also by several opportunistic diseases that take them into and out of hospital environment. During the hospital permanence, the patients expose their impaired immune system to the nosocomial virulent microorganisms, and acquire destructive nosocomial infections that sometimes can be lethal. Among several hospital syndromes described, little is known about infections in immunocompromised patients and how their immune system is able to determine the course of the infection. The objective of this study was to describe the major microorganisms involved in the nosocomial infections of HIV-1 seropositive patients associated with their immunological status. The survey was carried out with the Hospital Infection Control Service records, from University Hospital, Londrina, Paraná, Southern of Brazil, during the period from July 2003 to July 2004. From all the cases studied (n=969), 24 patients (2.5%) had AIDS diagnosis and a half of them was women with the mean of CD4+ T cells counts of 158/mm3. The main topography of the infection was pulmonary (50.0%) and the main isolated microorganisms were Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli. A major incidence of infection was observed in patients with CD4+ T cells counts lower than 50/mm3. The study of the relationship between the impairment of the immune system and infectious agents could provide a better healthcare of people living with HIV/AIDS and advances into the nosocomial infection control systems.

Oral lesions are common in women and children with HIV/AIDS and may decrease the overall quality of life in these patients because of pain, dry mouth, and difficulty in eating. An oral cavity screening is an easy, noninvasive, quick, and inexpensive procedure that provides nurses with invaluable information about the need for referral, treatment, and health education. Nurses can use the information obtained from a careful oral screening to decrease the symptoms experienced with oral lesions and optimize a patient's ability to chew and enjoy food. Common oral manifestations of HIV infection include fungal, viral, and bacterial infections, although neoplasms, periodontal disease, salivary gland disease, and lesions of uncertain origin are also seen. Oral lesions such as candidiasis, oral hairy leukoplakia, herpetic ulcers, and Kaposi's sarcoma are often among the first symptoms of HIV infection.

While the population of the southern United States is only 37% of the country's total, this region is experiencing 50% of new HIV diagnoses and 46% of new AIDS diagnoses. Specifically, Mississippi has the highest rates of new infection, the most AIDS deaths, the greatest number of people living with HIV/AIDS, and the fewest resources. Mississippi has the highest death rate in the country: 32.9 per 1,000. A Mississippian with HIV/AIDS is almost twice as likely to die as the average American with the virus (SHARP Report, 2010). Compounding the problem are government policy issues, such as disproportionate program funding; socio-economic issues, such as widespread poverty, housing insecurity, and the lack of access to care; and cultural issues, such as homophobia and social stigma. These factors are reflected in this study which examines the needs of people living with HIV/AIDS in a southern, rural county of Mississippi. From a representative sample of 218 HIV positive individuals, researchers identified the levels of need for housing, transportation, medical care, mental health care, substance abuse treatment, and education. The author discusses the reciprocal influences of these needs and HIV, the need for policy changes at the state and federal levels, and the need for resources that both support people living with HIV/AIDS and curb the rate of new infections.
HIV still primarily affects two groups in the UK--gay men and black African communities. Recent advances have revolutionised the treatment of HIV and many people with the virus are able to lead full and healthy lives. Nurses can help people with HIV to understand that good health is not just about feeling physically well--it is also about emotions, thoughts, relationships, environment and many other aspects of life. World Aids Day is the one day a year when we remember all those living with and affected by HIV across the world, as well as those who have died.

The AIDS pandemic continues to present us with unique scientific and public health challenges. Although the development of effective antiretroviral therapy has been a major triumph, the emergence of drug resistance requires active management of treatment regimens and the continued development of new antiretroviral drugs. Moreover, despite nearly 30 years of intensive investigation, we still lack the basic scientific knowledge necessary to produce a safe and effective vaccine against HIV-1. Animal models offer obvious advantages in the study of HIV/AIDS, allowing for a more invasive investigation of the disease and for preclinical testing of drugs and vaccines. Advances in humanized mouse models, non-human primate immunogenetics and recombinant challenge viruses have greatly increased the number and sophistication of available mouse and simian models. Understanding the advantages and limitations of each of these models is essential for the design of animal studies to guide the development of vaccines and antiretroviral therapies for the prevention and treatment of HIV-1 infection.

Operations research is mainly applied to decision making in industries and corporations using quantitative methods to optimize production. The applications of operations research in social sciences research or health research in HIV, service delivery, and program performance improvement are minimal. Considering the complexity of the HIV/AIDS epidemic, it is imperative to learn from operations research in scaling up HIV treatment, prevention, and intervention in resource-poor settings. In this article the author discusses the methodological issues in operations research within the context of HIV/AIDS research. The author also suggests a framework for using operations research in the field of HIV/AIDS research and program intervention.

The clinical, immunologic, and virologic effects and the pharmacokinetics of human immunodeficiency virus (HIV) human hyperimmune immunoglobulin (HIVIG) were assessed in 30 HIV-infected children aged 2-11 years. All had moderately advanced disease with an immune complex-dissociated (ICD) p24 antigen >70 pg/mL and were on stable antiviral therapy. Three groups of 10 children received 6 monthly infusions of 200, 400, or 800 mg/kg of HIVIG, and serial immunologic and virologic assays were performed. HIVIG doses as high as 800 mg/kg were safe and well tolerated. The half-life of HIVIG, determined by serial p24 antibody titers, was 13-16 days, the volume of distribution was 102-113 mL/kg, and clearance was 5.6-6.0 mL/kg/day. Plasma ICD p24 decreased during the infusions, but CD4 cell levels, plasma RNA copy number, cellular virus, immunoglobulin levels, and neutralizing antibody titers were minimally affected by the infusions. Clinical status did not change during the 6-month infusion and 3-month follow-up periods.

Mucosal immunity consists of innate and adaptive immune responses which can be influenced by systemic immunity. Despite having been the subject of intensive studies, it is not fully elucidated what exactly occurs after HIV contact with the female genital tract mucosa. The sexual route is the main route of HIV transmission, with an increased risk of infection in women compared to men. Several characteristics of the female genital tract make it suitable for inoculation, establishment of infection, and systemic spread of the virus, which causes local changes that may favor the development of infections by other pathogens, often called sexually transmitted diseases (STDs). The relationship of these STDs with HIV infection has been widely studied. Here we review the characteristics of mucosal immunity of the female genital tract, its alterations due to HIV/AIDS, and the characteristics of coinfections between HIV/AIDS and the most prevalent STDs.

ABSTRACT The generation of vaccines against HIV/AIDS able to induce long-lasting protective immunity remains a major goal in the HIV field. The modest efficacy (31.2%) against HIV infection observed in the RV144 phase III clinical trial highlighted the need for further improvement of HIV vaccine candidates, formulation, and vaccine regimen. In this study, we have generated two novel NYVAC vectors, expressing HIV-1 clade C gp140(ZM96) (NYVAC-gp140) or Gag(ZM96)-Pol-Nef(CN54) (NYVAC-Gag-Pol-Nef), and defined their virological and immunological characteristics in cultured cells and in mice. The insertion of HIV genes does not affect the replication capacity of NYVAC recombinants in primary chicken embryo fibroblast cells, HIV sequences remain stable after multiple passages, and HIV antigens are correctly expressed and released from cells, with Env as a trimer (NYVAC-gp140), while in NYVAC-Gag-Pol-Nef-infected cells Gag-induced virus-like particles (VLPs) are abundant. Electron microscopy revealed that VLPs accumulated with time at the cell surface, with no interference with NYVAC morphogenesis. Both vectors trigger specific innate responses in human cells and show an attenuation profile in immunocompromised adult BALB/c and newborn CD1 mice after intracranial inoculation. Analysis of the immune responses elicited in mice after homologous NYVAC prime/NYVAC boost immunization shows that recombinant viruses induced polyfunctional Env-specific CD4 or Gag-specific CD8 T cell responses. Antibody responses against gp140 and p17/p24 were elicited. Our findings showed important insights into virus-host cell interactions of NYVAC vectors expressing HIV antigens, with the activation of specific immune parameters which will help to unravel potential correlates of protection against HIV in human clinical trials with these vectors. IMPORTANCE We have generated two novel NYVAC-based HIV vaccine candidates expressing HIV-1 clade C trimeric soluble gp140 (ZM96) and Gag(ZM96)-Pol

Observational cross-sectional study carried out at Omdurman National Voluntary Counseling and Testing Centre, Sudan covered 870 participants. Sociodemographic data as well as information related to sexual behavior were collected. Results. Most of the respondents were knowledgeable about the true transmission modes for AIDS virus. Very few respondents knew someone infected with AIDS (4.5%), died of AIDS (8.1%), accepted to live with someone infected with AIDS (4.7%) or to work with someone infected with AIDS (2.1%). Regarding sexual behavior, 96.5% had reported their first sexual experience between 20 and 30 years, with 85.7% reporting one or two partners, and only 1.8% reported using condom. Multivariate logistic regression showed that circumcision, religion, marital status, age at first sex, number of sexual partners, education level, and misconception of knowledge are the main risk factors associated with HIV/AIDS. Conclusion. Our results showed that a number of diversity risk factors were associated with HIV/AIDS. It is unlikely that a holistic approach will be found to immediately change sexual-risk-relating behavior. Interventions including sustained educational programs, promotion of condom, and encouragement of voluntary testing and active involvement of the country's political and religious leaders will be needed to alleviate this problem.

Bone marrow gene therapy remains an attractive option for treating chronic immunological diseases, including acquired immunodeficiency syndrome (AIDS) caused by human immunodeficiency virus (HIV). This technology combines the differentiation and expansion capacity of hematopoietic stem cells (HSCs) with long-term expression of therapeutic transgenes using integrating vectors. In this review we summarize the potential of bone marrow gene therapy for the treatment of HIV/AIDS. A broad range of antiviral strategies are discussed, with a particular focus on RNA-based therapies. The idea is to develop a durable gene therapy that lasts the life span of the infected individual, thus contrasting with daily drug regimens to suppress the virus. Different approaches have been proposed to target either the virus or cellular genes encoding co-factors that support virus replication. Some of these therapies have been tested in clinical trials, providing proof of principle that gene therapy is a safe option for treating HIV/AIDS. In this review several topics are discussed, ranging from the selection of the antiviral molecule and the viral target to the optimal vector system for gene delivery and the setup of appropriate preclinical test systems. The molecular mechanisms used to formulate a cure for HIV infection are described, including the latest antiviral strategies and their therapeutic applications. Finally, a potent combination of anti-HIV genes based on our own research program is described. PMID:26193303

Recent announcements in the news of HIV/AIDS contraction by famous sports figures have focused world attention on the fact that athletes are not immune to this deadly virus. In view of this, we reviewed the literature to examine what studies have been directed specifically at the athletic population and HIV/AIDS. Unfortunately, because of the relatively new nature of this problem, little data exists for examination. A panel of experts was assembled to participate in a Delphi methodology project. This educational study was designed to examine three issues surrounding the athletic community and HIV/AIDS. The three questions examined in this study were: 1) should medical testing be undertaken within the athletic community to determine exposure to the virus; 2) if testing is undertaken, what privacy/confidentiality measures should be incorporated to protect the individual and the results of the test; and 3) what educational interventions should be developed and implemented to help the athlete understand the disease and prevent the spread. The responses from the Delphi participants indicate that the HIV/AIDS dilemma is a societal issue and should not single out a segment of the population—in this case the athletic community. The panel also indicated that privacy and confidentiality are crucial in protecting the individual athlete and test results. The development and implementation of educational interventions is the most important component in the entire issue of HIV/AIDS and the athletic community. PMID:16558273

Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p < 0.0001) and 5% death (p = 0.28) in the PC group. Relapse occurred in 53% of the nonadherent patients but not in the adherent patients (p < 0.0001). Sixty-seven percent of patients with initial central nervous system (CNS) histoplasmosis relapsed compared to 15% of patients without CNS involvement (p = 0.0004), which may be accounted for by nonadherence. In addition, patients with antigenuria above 2.0 ng/mL at 1-year follow-up were 12.82 times (95% confidence interval, 2.91-55.56) more likely to relapse compared to those with antigenuria below 2.0 ng/mL. Discontinuation of antifungal therapy was safe in adherent patients who completed at least 1 year of antifungal treatment, and had CD4 counts >150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.
Short Communication: Current Prevalence and Risk Factors Associated with Human T Lymphotropic Virus Type 1 and Human T Lymphotropic Virus Type 2 Infections Among HIV/AIDS Patients in São Paulo, Brazil.

During the 1990s, high prevalences of HIV/human T lymphotropic virus type 1 (HTLV-1) and HIV/human T lymphotropic virus type 2 (HTLV-2) coinfections were detected in São Paulo, Brazil in association with intravenous drug use (IDU). The current prevalences and risk factors for HIV/HTLV-1/-2 were evaluated in 1,608 patients attending the AIDS/STD Reference and Training Center in São Paulo. Blood samples were analyzed for HTLV-1/2-specific antibodies using enzyme immunoassays (EIA Murex HTLV-I+II, Diasorin, and Gold ELISA HTLV-I+II, REM) and immunoblotting (HTLV Blot 2.4, MP Biomedicals and INNO-LIA HTLV-I/II, Innogenetics) and for the pol proviral DNA segments of HTLV-1 and HTLV-2 by "in-house" real-time PCR. These analyses revealed that 50 (3.11%) of the samples were HTLV positive, including 25 (1.55%) that were HTLV-1 positive, 21 (1.31%) that were HTLV-2 positive, and 4 (0.25%) that were HTLV positive (untypeable). The median age of the HIV/HTLV-coinfected individuals was 50 years versus 44 years in the overall population (p=0.000). The risk factors associated with HIV/HTLV-1/-2 coinfections were female gender (OR 3.26, 1.78-5.95), black/pardo color (OR 2.21, 1.21-4.03), infection with hepatitis B virus (HBV) (OR 4.27, 2.32-7.87) or hepatitis C virus (HCV) (OR 24.40, 12.51-48.11), and intravenous drug use (IDU) (OR 30.01, 15.21-59.29). The current low prevalence of HTLV-1/2 in HIV-infected patients in São Paulo could be explained in part by programs providing IDUs with sterile needles and syringes and changes in the drug usage patterns of individuals from injecting cocaine to smoking crack cocaine.

During the spread of human immunodeficiency virus type 1 (HIV-1) in the mucosa, the entire genetic diversity of the viruses is significantly reduced. The vast majority of HIV-1 mucosal infections are established by one or a few viruses and ultimately develop into systemic infections, thus the initial virus is called transmitted/founder virus (T/F virus). The study of T/F virus will benefit understanding its key characteristics resulting in successful viral replication in the new host body, which may provide novel strategies for the development of AIDS vaccines, pre-exposure prophylaxis and other therapeutic interventions. In this review, we summarize the discovery and evolutionary characteristics of T/F virus as well as early immune response after HIV-1 infection, which will establish the basis to explore the features of T/F viruses.

Primate lentiviruses exhibit narrow host tropism, reducing the occurrence of zoonoses but also impairing the development of optimal animal models of AIDS. To delineate the factors limiting cross-species HIV-1 transmission, we passaged a modified HIV-1 in pigtailed macaques that were transiently depleted of CD8(+) cells during acute infection. During adaptation over four passages in macaques, HIV-1 acquired the ability to antagonize the macaque restriction factor tetherin, replicated at progressively higher levels, and ultimately caused marked CD4(+) T cell depletion and AIDS-defining conditions. Transient treatment with an antibody to CD8 during acute HIV-1 infection caused rapid progression to AIDS, whereas untreated animals exhibited an elite controller phenotype. Thus, an adapted HIV-1 can cause AIDS in macaques, and stark differences in outcome can be determined by immunological perturbations during early infection.

Despite tremendous efforts over the course of many years, the quest for an effective HIV vaccine by the classical method of active immunization remains largely elusive. However, two recent studies in mice and macaques have now demonstrated a new strategy designated as Vectored ImmunoProphylaxis (VIP), which involves passive immunization by viral vector-mediated delivery of genes encoding broadly neutralizing antibodies (bnAbs) for in vivo expression. Robust protection against virus infection was observed in preclinical settings when animals were given VIP to express monoclonal neutralizing antibodies. This unorthodox approach raises new promise for combating the ongoing global HIV pandemic. In this article, we survey the status of antibody gene transfer, review the revolutionary progress on isolation of extremely bnAbs, detail VIP experiments against HIV and its related virus conduced in humanized mice and macaque monkeys, and discuss the pros and cons of VIP and its opportunities and challenges towards clinical applications to control HIV/AIDS endemics.

Social stigma has been inextricably linked with HIV and AIDS since the epidemic erupted in the early 1980s. The stigma that has built up around HIV and AIDS is generally regarded as having a negative impact on the quality of life of HIV-positive people and on general prevention efforts. Current attempts to combat HIV-related stigma focus on increasing the acceptance of HIV among the stigmatizing public and stigmatized individuals alike. In this, the global HIV-positive community is being increasingly called upon to ;humanize' the virus, not least through public displays of HIV 'positive' health and public ;positive' speaking. This article critically explores the constitutive effects and inherent power relations of HIV Positive Speakers' Bureaus (PSBs) as a platform for such a display. Adopting a post-structuralist discourse analytic approach, we explore accounts of positive-speaking and HIV health from HIV-related non-government organizations in India and in PSB training manuals. In particular, we highlight ways in which positive-speaking in India can be seen to have significant (re)stigmatizing effects by way of ambivalent and hyper-real configurations of HIV 'positive' identity and life.
Background A legacy of colonial rule coupled with a devastating 16-year civil war through 1992 left Mozambique economically impoverished just as the human immunodeficiency virus (HIV) epidemic swept over southern Africa in the late 1980s. The crumbling Mozambican health care system was wholly inadequate to support the need for new chronic disease services for people with the acquired immunodeficiency syndrome (AIDS). Methods To review the unique challenges faced by Mozambique as they have attempted to stem the HIV epidemic, we undertook a systematic literature review through multiple search engines (PubMed, Google Scholar™, SSRN, AnthropologyPlus, AnthroSource) using Mozambique as a required keyword. We searched for any articles that included the required keyword as well as the terms 'HIV' and/or 'AIDS', 'prevalence', 'behaviors', 'knowledge', 'attitudes', 'perceptions', 'prevention', 'gender', drugs, alcohol, and/or 'health care infrastructure'. Results UNAIDS 2008 prevalence estimates ranked Mozambique as the 8th most HIV-afflicted nation globally. In 2007, measured HIV prevalence in 36 antenatal clinic sites ranged from 3% to 35%; the national estimate of was 16%. Evidence suggests that the Mozambican HIV epidemic is characterized by a preponderance of heterosexual infections, among the world's most severe health worker shortages, relatively poor knowledge of HIV/AIDS in the general population, and lagging access to HIV preventive and therapeutic services compared to counterpart nations in southern Africa. Poor education systems, high levels of poverty and gender inequality further exacerbate HIV incidence. Conclusions Recommendations to reduce HIV incidence and AIDS mortality rates in Mozambique include: health system strengthening, rural outreach to increase testing and linkage to care, education about risk reduction and drug adherence, and partnerships with traditional healers and midwives to effect a lessening of stigma.

More than decades have already elapsed since human immunodeficiency virus (HIV) was identified as the causative agent of acquired immunodeficiency syndrome (AIDS). The HIV has since spread to all parts of the world with devastating effects. In sub-saharan Africa, the HIV/AIDS epidemic has reached unprecedented proportions. Safe, effective and affordable HIV/AIDS vaccines for Africans are therefore urgently needed to contain this public health problem. Although, there are challenges, there are also scientific opportunities and strategies that can be exploited in the development of HIV/AIDS vaccines for Africa. The recent RV144 Phase III trial in Thailand has demonstrated that it is possible to develop a vaccine that can potentially elicit modest protective immunity against HIV infection. The main objective of this review is to outline the key scientific opportunities, challenges and strategies in HIV/AIDS vaccine development in Africa. PMID:26185576

The number of children orphaned by HIV/AIDS in the developing world has reached crisis proportions. In Sub-Saharan Africa, HIV/AIDS has exacerbated poverty in many communities and has weakened the capacity of many countries to care for their orphaned children. The present article discusses orphanage care and its alternatives in Sub-Saharan Africa. The physical and mental health effects of parental loss are discussed and the psychosocial impacts of institutional care are reviewed. Foster care is discussed as a potential long-term strategy to help communities cope with the rising numbers of HIV/AIDS orphans. The importance of community-based care is highlighted.

This review provides information on the epidemiology, economic impact, and intervention strategies for the human immunodeficiency virus (HIV)/AIDS pandemic in developing countries. According to the World Health Organization and the Joint United Nations Programme on HIV/AIDS (UNAIDS) at the end of 1999, an estimated 34.3 million people were living with HIV/AIDS. Most of the people living with HIV, 95% of the global total, live in developing countries. Examples of the impact of HIV/AIDS in Africa, Asia, Latin America, the Caribbean, and the Newly Independent States provide insight into the demographics, modes of exposure, treatment and prevention options, and the economic effect of the epidemic on the global community. The epidemic in each region of the world is influenced by the specific risk factors that are associated with the spread of HIV/AIDS and the responses that have evolved to address it. These influences are important in developing HIV/AIDS policies and programs to effectively address the global pandemic. PMID:11292641

Sexually transmitted diseases (STD) / reproductive tract infections (RTI) including acquired immunodeficiency syndrome (AIDS) / human immunodeficiency virus (HIV) infections among the women of reproductive age group: a review.
Nahar, A; Azad, A K
Despite great improvements in preventing and treating sexually transmitted diseases (STDs) and reproductive tract infections (RTIs), including HIV/AIDS, infections have been increasing significantly throughout the world. The problem of STDs, RTIs, and HIV/AIDS among women aged 15-49 years is increasing at an alarming rate. Certain biological risk factors and cultural practices enhance the vulnerability of women of reproductive age. Among these biological risks are age, gender, blood transfusion during pregnancy and childbirth, and the development of asymptomatic STDs/RTIs. These are exacerbated by cultural practices like douching with pharmaceutical products, use of intravaginal substances, and the practice of anal sex. STDs, RTIs, and HIV/AIDS affect female reproductive health in certain ways: mother-to-child transmission, effects on pregnancy (spontaneous abortion, premature birth, stillbirth, low birth weight, ectopic pregnancy), infertility, cancer, and rise in AIDS-related mortality. On the other hand, society will experience an increase in orphans, destabilization of the family unit, and a reduction in family income. Considering the impact of these diseases on the reproductive health of women and the community, measures should be taken to prevent and control the epidemic. The paper discusses certain interventions and diagnostic and preventive strategies against STDs, RTIs, and HIV/AIDS.

This study uses Goffman's [1963. Stigma: Notes on the Management of Spoiled Identity, New Jersey, Prentice-Hall] theory of stigma as an intellectual scaffold to help understand the social meaning of HIV/AIDS stigma from People Living with HIV/AIDS. The study adopts a qualitative approach because of its appropriateness for unravelling subjective phenomena such as the experiences of HIV/AIDS stigma. In-depth interviews were conducted with 10 HIV-positive employees of a retailing company located in the Western Cape province of South Africa who volunteered to participate in the study. The participants with the discreditable stigma internalised society's prejudice towards those living with the virus. As a result, the participants relied on self-isolation and social withdrawal to cope with enacted stigma. Managing information about one's status and deciding whether, who, when, etc., to tell are crucial questions. The participants feared being devalued by family, friends, co-workers and the community. In concurrence with Goffman , the HIV/AIDS stigma is seen as about relationships.

African Americans are the most affected by HIV/AIDS. Both males and females continue to be disproportionately affected by HIV/AIDS. They are often drug users or participate in street/drug subculture. Recent weather disasters have required identification of knowledge, beliefs, conduct norms and behavior patterns that are HIV/AIDS risk factors for disaster survivors. This paper examines patterns of behavior and common practices related to HIV among disaster survivors. Study background Data for this paper come from a three year renewal project which focused upon the processes by which illicit drug markets were reformulated after disasters and practices of risk behaviors for HIV/AIDS. Hurricanes Katrina, Gustav and Ike presented the opportunity to examine the impact of disasters upon risky behavior among illicit drug users and sellers. Methods From 2010-2013 ethnographic study was conducted in New Orleans, Louisiana, Houston and Galveston, Texas. Staff completed in-depth interviews with 132 focal respondents of drug users and sellers. There were 57 focus groups with 243 focus group participants; 350 drug using/selling respondents completed a survey protocol (CAPI), organized around their experiences during the hurricanes. Results In both cities respondents displayed knowledge about HIV, modes of transmission and knew that HIV infection can lead to AIDS. Knowledge about time between exposure and infection was mostly imprecise. Most respondents reported they had been tested for HIV multiple times. A large number of participants reported learning about HIV in school, older respondents (mid-40s to 60) reported their knowledge came from television or the streets. Participants expressed fatalistic attitudes toward HIV, believing the virus was fatal even with medication. Conclusion With the increase of disasters, more attention needs to be placed upon programs focused on drug consumers. Schools, clinics, public information sources, i.e., TV and radio can make understanding

Current therapy for controlling human immunodeficiency virus (HIV-1) infection and preventing acquired immunodeficiency syndrome (AIDS) progression has profoundly decreased viral replication in cells susceptible to HIV-1 infection, but it does not eliminate the low level of viral replication in latently infected cells, which contain integrated copies of HIV-1 proviral DNA. There is an urgent need for the development of HIV-1 genome eradication strategies that will lead to a permanent or "sterile" cure of HIV-1/AIDS. In the past few years, novel nuclease-initiated genome editing tools have been developing rapidly, including zinc finger nucleases (ZFNs), transcription activator-like effector nucleases (TALENs), and the CRISPR/Cas9 system. These surgical knives, which can excise any genome, provide a great opportunity to eradicate the HIV-1 genome by targeting highly conserved regions of the HIV-1 long terminal repeats or essential viral genes. Given the time consuming and costly engineering of target-specific ZFNs and TALENs, the RNA-guided endonuclease Cas9 technology has emerged as a simpler and more versatile technology to allow permanent removal of integrated HIV-1 proviral DNA in eukaryotic cells, and hopefully animal models or human patients. The major unmet challenges of this approach at present include inefficient nuclease gene delivery, potential off-target cleavage, and cell-specific genome targeting. Nanoparticle or lentivirus-mediated delivery of next generation Cas9 technologies including nickase or RNA-guided FokI nuclease (RFN) will further improve the potential for genome editing to become a promising approach for curing HIV-1/AIDS.
No cure has been found for HIV/AIDS. Therefore, until one is found which is affordable and feasible for use in developing countries, preventing HIV infection is the best way to combat the HIV/AIDS pandemic. All of the many biological characteristics of HIV which affect its rate of spread in a population can be affected through individual behavior. The two most important behaviors which spread HIV are having sexual intercourse with an HIV-infected sex partner without using a condom and sharing unsterilized drug injecting equipment. Strategies to reduce risky behavior include providing information, lowering the costs of condom use and safe injecting behavior, and raising the costs of risky behavior. The costs of condom use include the financial and time costs of buying the condoms, the potential inconvenience and social embarrassment of buying and using them, and reduced pleasure among some users. IV drug users face the problems of getting into and remaining in drug treatment programs, and obtaining sterile injecting equipment. Government priorities in preventing HIV/AIDS and mobilizing political support against AIDS are discussed.
HIV/AIDS has always been one of the most thoroughly global of diseases. In the era of widely available anti-retroviral therapy (ART), it is also commonly recognised as a chronic disease that can be successfully managed on a long-term basis. This article examines the chronic character of the HIV/AIDS pandemic and highlights some of the changes we might expect to see at the global level as HIV is increasingly normalised as "just another chronic disease". The article also addresses the use of this language of chronicity to interpret the HIV/AIDS pandemic and calls into question some of the consequences of an uncritical acceptance of concepts of chronicity.

No studies to date have assessed the quantity of HIV/AIDS-related media on the Internet. We assessed the quantity of language-specific HIV/AIDS Internet-based news coverage, and the correlation between country-specific HIV/AIDS news coverage and HIV/AIDS prevalence. Internet-based HIV/AIDS news articles were queried from Google News Archives for 168 countries, for the year 2007, in the nine most commonly spoken languages worldwide. English, French and Spanish sources had the greatest number of HIV/AIDS-related articles, representing 134,000 (0.70%), 11,200 (0.65%) and 24,300 (0.49%) of all news articles, respectively. A strong association between country-specific HIV/AIDS news coverage and HIV/AIDS prevalence was found, Spearman's rank correlation: 0.6 (P < 0.001). Among countries with elevated HIV/AIDS prevalence (> or =10%), the volume of HIV/AIDS-specific media was highest in Swaziland (15.9%) and Malawi (13.2%), and lowest in South Africa (4.8%) and Namibia (4.9%). Increased media attention should be placed on countries with high HIV/AIDS prevalence and limited HIV/AIDS-specific news coverage.

Due to their geographical mobility and long periods of separation from intimate partners, migrant workers are at increased risk for a variety of sexually transmitted infections (STIs) including HIV/AIDS. This study sought to investigate patterns in HIV/AIDS related knowledge, attitudes and sexual behaviour in migrant workers in Croatia. In 2003, 566 male migrant workers were recruited during regular required medical examinations and surveyed at seven locations throughout the country. Each participant was asked to complete a self-administered KABP (sexual knowledge, attitudes, beliefs and practices) questionnaire. The average age of respondents was 38.2 years and the majority worked as seafarers (77.3%) and construction workers (20.5%). Only 18.5% of respondents were able to correctly answer all 13 questions assessing knowledge of HIV/AIDS. Seafarers reported higher levels of knowledge than did construction workers. The average respondent reported having had two sexual partners in the last 12 months, with slightly over half of the respondents (55.3%) reporting condom use at their last intercourse with a casual partner. One fifth of the respondents (20.3%) who reported having had intercourse with a sex worker during the last year reported not using condoms at last intercourse. The number of sexual partners was correlated with age, marital status, faith in God, and personal HIV risk assessment. Attitudes toward condom use, co-workers' HIV/AIDS concerns and the duration of migrant status (within the last two years) were shown to be significant correlates of condom use at last intercourse with a casual partner. The effect of HIV/AIDS related knowledge on analyzed behaviors did not reach statistical significance. Inadequate patterns of migrant workers' condom use, gaps in knowledge about HIV transmission and modes of protection, as well as widespread ignorance regarding available anonymous HIV testing found by this study suggest a critical need for expert intervention to

Despite tremendous advances in HIV care and increased funding for treatment, morbidity and mortality from HIV/AIDS in developing countries remains unacceptably high. A major contributing factor is that globally over 800 million people remain chronically undernourished and the HIV epidemic largely overlaps with populations already suffering from low diet quality and quantity. We present an updated review of the relationship between HIV, nutritional deficiencies and food insecurity, and consider efforts to interrupt this cycle at a programmatic level. As HIV infection progresses, it causes a catabolic state and increased susceptibility to infection which are compounded by lack of caloric and other nutrient intake, leading to progressive worsening of malnutrition. Despite calls from national and international organizations to integrate HIV and nutrition programs, data are lacking on how such programs can be effectively implemented in resource-poor settings, on the optimum content and duration of nutrition support and on ideal target recipients.

Understanding of the human microbiome continues to grow rapidly; however, reports on changes in the microbiome after HIV infection are still limited. This review surveys the progress made in methodology associated with microbiome studies and highlights the remaining challenges to this field. Studies have shown that commensal oral, gut, vaginal, and penile bacteria are vital to the health of the human immune system. Our studies on crosstalk among oral and gastrointestinal soluble innate factors, HIV, and microbes indicated that the oral and gut microbiome was altered in the HIV-positive samples compared to the negative controls. The importance of understanding the bacterial component of HIV/AIDS, and likelihood of “crosstalk” between viral and bacterial pathogens, will help in understanding the role of the microbiome in HIV-infected individuals and facilitate identification of novel antiretroviral factors for use as novel diagnostics, microbicides, or therapeutics against HIV infection.

HIV (Human Immunodeficiency virus) causes (acquired immunodeficiency syndrome) AIDS, in which the immune system of body totally fails to develop any defense against the foreign invaders. Infection with HIV occurs by transfer of blood, semen, and breast milk. HIV/AIDS is a global problem and it results nearly 25 million deaths worldwide. Developing countries like Pakistan have issues regarding Public Health. Currently, epidemic of HIV/AIDS is established in Pakistan and there is a threat of an expanded HIV/AIDS outbreak in the country. The major reason is that population is engaging in high-risk practices, low awareness about HIV/AIDS, and treacherous blood transfusion practices. A supplementary threat to Pakistan is India because both sharing a border and India is facing a rapidly growing HIV/AIDS epidemic. Local NGOs, National and International organizations are warning that in near future Pakistan may experiences bad situation regarding HIV/AIDS.In the present article we focused current situation of surveillance of HIV/AIDS, its virology, genotype, diagnostics, high-risk groups, reasons of vulnerability in Pakistani population, and the role of different national and international organizations in this situation.

The development of an animal model of human immunodeficiency virus type 1 (HIV-1)/AIDS that is suitable for preclinical testing of antiretroviral therapy, vaccines, curative strategies, and studies of pathogenesis has been hampered by the human-specific tropism of HIV-1. Although simian immunodeficiency virus (SIV) or HIV-1/SIV chimeric viruses (SHIVs)-rhesus macaque models are excellent surrogates for AIDS research, the genetic differences between SIV or SHIV and HIV-1 limit their utility as model systems. The identification of innate retro viral restriction factors has increased our understanding about blockades to HIV-1 replication in macaques and provided a guide for the construction of macaque-tropic HIV-1 clones. However, while these viruses replicate in macaque cells in vitro, they are easily controlled and have not caused AIDS in host animals, indicating that we may not fully understand the restrictive barriers of innate immunity. In this review, we discuss recent findings regarding HIV-1 restriction factors, particularly as they apply to cross-species transmission of primate lentiviruses and the development of a macaque model of HIV-1/AIDS.

The incorporation of human immune deficiency virus/acquired immune deficiency syndrome (HIV/AIDS) into identity over time was examined by collecting data from the same 11 HIV-positive individuals at 3 points in time (in 1995, early 1998, and late 1999). By the time of their semi-structured interviews in late 1999, the seven men and four women…

School-based HIV/AIDS education is a common and well-proven intervention strategy for providing information on HIV/AIDS to young people. However, lack of skills among teachers for imparting sensitive information to students can lead to programme failure in terms of achieving goals. A cross-sectional study was conducted among teachers to identify the factors that support or hinder their role in HIV/AIDS education. A self-administered questionnaire was used for interviewing teachers from randomly-selected schools in two adjacent districts in Bangladesh. Based on exposure to teachers' training, the districts were divided into control and intervention areas and the teachers' ability, skill, and their participation in HIV/AIDS education were compared between the districts. Trained teachers in the intervention schools were more likely to participate, less likely to face difficulties, and more likely to use interactive teaching methods in HIV/ AIDS classes compared to the controls who did not receive any training. Inadequate allocation of time for conducting the HIV/AIDS class was found to be barriers to HIV/AIDS education that suggest the need to provide teachers with more support in terms of training and logistics.

OBJECTIVE To analyze HIV/AIDS positive individual’s perception and attitudes regarding dental services. METHODS One hundred and thirty-four subjects (30.0% of women and 70.0% of men) from Nuevo León, Mexico, took part in the study (2014). They filled out structured, analytical, self-administered, anonymous questionnaires. Besides the sociodemographic variables, the perception regarding public and private dental services and related professionals was evaluated, as well as the perceived stigma associated with HIV/AIDS, through a Likert-type scale. The statistical evaluation included a factorial and a non-hierarchical cluster analysis. RESULTS Social inequalities were found regarding the search for public and private dental professionals and services. Most subjects reported omitting their HIV serodiagnosis and agreed that dentists must be trained and qualified to treat patients with HIV/AIDS. The factorial analysis revealed two elements: experiences of stigma and discrimination in dental appointments and feelings of concern regarding the attitudes of professionals or their teams concerning patients’ HIV serodiagnosis. The cluster analysis identified three groups: users who have not experienced stigma or discrimination (85.0%); the ones who have not had those experiences, but feel somewhat concerned (12.7%); and the ones who underwent stigma and discrimination and feel concerned (2.3%). CONCLUSIONS We observed a low percentage of stigma and discrimination in dental appointments; however, most HIV/AIDS patients do not reveal their serodiagnosis to dentists out of fear of being rejected. Such fact implies a workplace hazard to dental professionals, but especially to the very own health of HIV/AIDS patients, as dentists will not be able to provide them a proper clinical and pharmaceutical treatment.

The Women and AIDS Research Program (International Center for Research on Women) has identified a series of obstacles to preventing HIV infection among women, including social norms that mandate female ignorance about sexual matters, women's economic dependence on men, widespread acceptance of male promiscuity, and violence against women. Most AIDS prevention programs fail to challenge these contextual determinants and continue to focus on the promotion of condom use among men. Recommendations to empower women and improve their status are dismissed as long-term measures outside the domain of AIDS prevention. Feasible, however, is the modification of existing AIDS prevention programs to ensure they are gender-sensitive. This would mean measures such as providing services at times that are convenient to women and integrating services to reduce waiting and travelling times. To address the contextual issues at the root of women's vulnerability to HIV, AIDS prevention programs can link up with economic interventions such as credit programs, agricultural extension services, and women's cooperatives. Moreover, AIDS programs can provide HIV-infected women with social support through group educational sessions or counseling. Finally, because improvements in women's socioeconomic status are essential for the success of all AIDS prevention, program managers should be in the forefront of broader struggles to enact policy changes to eliminate gender-based discrimination and inequality.

Human immunodeﬁciency virus (HIV) infection has become devastating in last a few years. Nearly 7400 new infection cases are coming every day. Highly active antiretroviral therapy (HAART), which involves combination of at least three antiretroviral (ARV) drugs, has been used to extend the life span of the HIV-infected patients. HAART has played an important role to reduce mortality rate in the developed countries but in the developing countries condition is still worst with millions of people being infected by this disease. For the improvement of the situation, nanotechnology-based drug system has been explored for the HIV therapeutics. Nanosystems used for HIV therapeutics offer some unique advantage like enhancement of bioavailability, water solubility, stability, and targeting ability of ARV drugs. Main nanotechnology-based systems explored for HIV therapeutics are liposomes, nanoparticles, niosomes, polymeric micelles, and dendrimers. Present manuscript reviews conventional method of HIV therapeutics and recent advances in the field of nanotechnology-based systems for treatment of HIV-AIDS.

Thirty years after the first described AIDS case, fifteen years after the advent of highly active antiretroviral therapy, miracles continue. 2011 has seen important developments, notably in the fields of prevention and of antiretroviral treatment. Condoms are no longer the only way of preventing sexually transmitted HIV: antiretroviral drugs used by HIV-negative individuals (to prevent HIV acquisition) or by HIV-infected individuals (to prevent transmission) are efficient new tools for such prevention. In parallel, new one pill once daily combination therapies have been submitted (or are in the process of being submitted) to regulatory authorities. Finally, the first phase I clinical trials of gene therapy are being presented later this year, allowing the hope of HIV cure.
Abstract Established under Section 25 of the HIV Prevention and Control Act of 2006, the HIV and AIDS Tribunal of Kenya is the only HIV-specific statutory body in the world with the mandate to adjudicate cases relating to violations of HIV-related human rights. Yet, very limited research has been done on this tribunal. Based on findings from a desk research and semi-structured interviews of key informants conducted in Kenya, this article analyzes the composition, mandate, procedures, practice, and cases of the tribunal with the aim to appreciate its contribution to the advancement of human rights in the context of HIV. It concludes that, after a sluggish start, the HIV and AIDS Tribunal of Kenya is now keeping its promise to advance the human rights of people living with and affected by HIV in Kenya, notably through addressing barriers to access to justice, swift ruling, and purposeful application of the law. The article, however, highlights various challenges still affecting the tribunal and its effectiveness, and cautions about the replication of this model in other jurisdictions without a full appraisal.

Bangladesh initiated an early response to the HIV epidemic starting in the mid-1980s. Since then, the res-ponse has been enhanced considerably, and many HIV-prevention interventions among the most at-risk populations and the general youth are being undertaken. Alongside prevention activities, gathering of data has been a key activity fostered by both the Government and individual development partners. This paper reviews available sources of data, including routine surveillance (HIV and behavioural among most at-risk populations), general population surveys, and various research studies with the aim to understand the dynamics of the HIV epidemic in Bangladesh. Available data show that the HIV epidemic is still at relatively low levels and is concentrated mainly among injecting drug users (IDUs) in Dhaka city. In addition, when the passively-reported cases were analyzed, another population group that appears to be especially vulnerable is migrant workers who leave their families and travel abroad for work. However, all sources of data confirm that risk behaviours that make individuals vulnerable to HIV are high—this is apparent within most at-risk populations and the general population (adult males and youth males and females). Based on the current activities and the sources of data, modelling exercises of the future of the HIV epidemic in Dhaka suggest that, if interventions are not enhanced further, Bangladesh is likely to start with an IDU-driven epidemic, similar to other neighbouring countries, which will then move to other population groups, including sex workers, males who have sex with males, clients of sex workers, and ultimately their families. This review reiterates the often repeated message that if Bangladesh wants to be an example of how to avert an HIV epidemic, it needs to act now using evidence-based programming. PMID:18831227

This study retrospectively analyzed Chinese publicly reported data on Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS). The HIV/AIDS morbidity (1/100,000) and mortality (1/100,000) rates in China continually increased from 0.23 and 0.06 in 2004 to 1.53 and 0.69 in 2011, respectively. The AIDS case fatality rate decreased yearly from 53.57% in 2008 to 45.11% in 2011, and the fatality rate in rural areas (0.25-0.42%) was higher than that in cities (0.13-0.22%). The number of HIV/AIDS patients discharged from city-level hospitals increased from 329 in 2004 to 7,266 in 2011, and this number was higher than the number of similar patients discharged from county-level (rural) hospitals (the number of HIV/AIDS patients increased from 252 in 2004 to 5,957 in 2011). The factors contributing to these trends include: enhanced physician HIV/AIDS education regarding diagnosis, intervention, monitoring, testing, and treatment; improved safety of blood collection and use; and improved management of HIV/AIDS patients. Therefore, HIV/AIDS prevention and control in rural areas of China is the key to reducing HIV transmission and mortality in China.

HIV infection and AIDS pose special challenges to employers. Myriad laws affect how the employer must respond when an applicant or employee is infected with HIV or is ill due to AIDS. An overall compliance strategy should include thorough knowledge of those laws and a policy on HIV and AIDS, put in place before a crisis occurs.

In this paper, we present an Human Immunodeficiency Virus (HIV)/Acquired Immune Deficiency Syndrome (AIDS) drug-resistant model using an ordinary differential equation (ODE) model on scale-free networks. We derive the threshold for the epidemic to be zero in infinite scale-free network. We also prove the stability of disease-free equilibrium (DFE) and persistence of HIV/AIDS infection. The effects of two immunization schemes, including proportional scheme and targeted vaccination, are studied and compared. We find that targeted strategy compare favorably to a proportional condom using has prominent effect to control HIV/AIDS spread on scale-free networks.

Human immunodeficiency virus and acquired immune deficiency syndrome (HIV/AIDS) is pandemic. It has affected nearly 60 million people since the detection of the disease in 1981 to date. In this paper basic deterministic HIV/AIDS model with mass action incidence function are developed. Stability analysis is carried out. And the disease free equilibrium of the basic model was found to be locally asymptotically stable whenever the threshold parameter (RO) value is less than one, and unstable otherwise. The model is extended by introducing two optimal control strategies namely, CD4 counts and treatment for the infective using optimal control theory. Numerical simulation was carried out in order to illustrate the analytic results.
The history of mankind over many millennia has been marred by many epidemics caused by viruses which infect the human respiratory system and alimentary tract. The current HIV-1/AIDS pandemic, however, is caused by one virus mutant, HIV-1M, which has evolved to infect humans through the genitals. The virus is able to use the innate system cells of the infected individual to inactivate the adaptive immune system, causing AIDS. The mechanisms used by HIV-1M to inhibit the immune system are presented. Understanding the viral mechanisms is leading to novel antiviral treatments and an approach to an HIV-1 vaccine.

After nearly three decades of being virtually drug free, use of heroin and other illicit drugs has re-emerged in China as a major public health problem. One result is that drug abuse, particularly heroin injection, has come to play a predominant role in fueling China's AIDS epidemic. The first outbreak of HIV among China's IDUs was reported in the border area of Yunnan province between China and Myanmar where drug trafficking is heavy. Since then drug-related HIV has spread to all 31 provinces, autonomous regions and municipalities. This paper provides an overview to HIV/AIDS transmission through injection drug use in China. It begins with a brief history of the illicit drug trade in China, followed by a discussion of the emergence of drug related AIDS, and a profile of drug users and their sexual partners who have contracted the virus or who are vulnerable to infection. It ends by summarizing three national strategies being used by China to address both drug use and AIDS as major health threats.

The first confirmed case of HIV/AIDS in the Caribbean was reported in 1982, however a recent report by UNAIDS shows that the epidemic has risen to over 250,000 persons living with the virus with the highest prevalence rates shown to be in the Dominican Republic and Haiti. Various factors ranging from commercial sex trading to unsafe injection employed for drug abuse have been identified to play a contributing role in this increase. Also, the role and impact of tourism on the spread of HIV infection has been reported. Due to concerns shown by countries and territories who are dependent on tourism and that they rank amongst the most highly affected by HIV/AIDS in the region, this paper endeavours to examine the impact of HIV/AIDS and the contributing role of tourism to HIV/AIDS epidemic in the Caribbean.

There are number of Non-Governmental Organisations (NGOs) in South Africa that use sport as a tool to respond to Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS), however, little is reported about the outcomes and impact of these programmes. The aim of this study is to contribute to a generic monitoring and evaluation framework by improving the options for the use of outcome indicators of sport-based HIV/AIDS awareness programmes of selected NGOs in South Africa. A qualitative method study was carried out with seven employees of five selected NGOs that integrate sport to deliver HIV/AIDS programmes in South Africa. The study further involved six specialists/experts involved in the field of HIV/AIDS and an official from Sport Recreation South Africa (SRSA). Multiple data collection instruments including desktop review, narrative systematic review, document analysis, one-on-one interviews and focus group interview were used to collect information on outcomes and indicators for sport-based HIV/AIDS awareness programmes. The information was classified according to the determinants of HIV/AIDS. The overall findings revealed that the sport-based HIV/AIDS awareness programmes of five selected NGOs examined in this study focus on similar HIV prevention messages within the key priorities highlighted in the current National Strategic Plan for HIV/AIDS, STIs and TB of South Africa. However, monitoring and evaluating outcomes of sport-based HIV/AIDS programmes of the selected NGOs remains a challenge. A need exists for the improvement of the outcome statements and indicators for their sport-based HIV/AIDS awareness programmes. This study proposed a total of 51 generic outcome indicators focusing on measuring change in the knowledge of HIV/AIDS and change in attitude and intention towards HIV risk behaviours. In addition, this study further proposed a total of eight generic outcome indicators to measure predictors of HIV risk behaviour. The selected
This paper provides an empirical evaluation of adult HIV prevalence rates, foreign aid for HIV/AIDS programmes, and the amount of government spending on health care. It finds that there exists a statistically significant relationship between adult HIV prevalence rates and the amount of foreign funding for HIV/AIDS programmes, suggesting that need does in fact play some role in the allocation of HIV aid. It suggests there may be an additive relationship between foreign and domestic health spending, where governments turn the funding of their AIDS programmes over to foreign donors and instead put their own monies toward other parts of the health care system.

The spread of human immunodeficiency virus (HIV) infection and the resulting acquired immune deficiency syndrome (AIDS) is a major health concern in many parts of the world, and mathematical models are commonly applied to understand the spread of the HIV epidemic. To understand the spread of HIV and AIDS cases and their parameters in a given population, it is necessary to develop a theoretical framework that takes into account realistic factors. The current study used this framework to assess the interaction between individuals who developed AIDS after HIV infection and individuals who did not develop AIDS after HIV infection (pre-AIDS). We first investigated how probabilistic parameters affect the model in terms of the HIV and AIDS population over a period of time. We observed that there is a critical threshold parameter, R0, which determines the behavior of the model. If R0 ≤ 1, there is a unique disease-free equilibrium; if R0 < 1, the disease dies out; and if R0 > 1, the disease-free equilibrium is unstable. We also show how a Markov chain Monte Carlo (MCMC) approach could be used as a supplement to forecast the numbers of reported HIV and AIDS cases. An approach using a Monte Carlo analysis is illustrated to understand the impact of model-based predictions in light of uncertain parameters on the spread of HIV. Finally, to examine this framework and demonstrate how it works, a case study was performed of reported HIV and AIDS cases from an annual data set in Malaysia, and then we compared how these approaches complement each other. We conclude that HIV disease in Malaysia shows epidemic behavior, especially in the context of understanding and predicting emerging cases of HIV and AIDS.
The World Health Organization estimated that 2.2% of Nigeria's adult population was infected with HIV by the end of 1995. A 1993-94 sentinel surveillance report found a 3.8% HIV seroprevalence level among sexually active Nigerians sampled. HIV prevalence is rising in the country. Incidence and prevalence data are presented on HIV and AIDS in sections on antenatal clinics, HIV-1 and HIV-2, group variations, regional variations, age variations, prostitutes, and infection by blood. The Nigerian government has projected that there could be 7 million people infected with HIV in the country by the year 2000. Background is presented on the economy, living standards, health, and population. Vulnerability is then considered with regard to population mobility, drug trafficking, the vulnerability of women, the international sex trade, the military presence in Liberia, sexual attitudes, poverty, and ignorance. The responses of the government and the domestic nongovernment sector are then presented followed by description of external assistance from the World Bank, the US Agency for International Development, the British Overseas Development Agency, the World Health Organization, the private sector, and the European Commission.

Etiology, transmission and protection: Transmission of HIV, the causative agent of AIDS, occurs predominantly through bodily fluids. Factors that significantly alter the risk of HIV transmission include male circumcision, condom use, high viral load, and the presence of other sexually transmitted diseases. Pathology/Symptomatology: HIV infects preferentially CD4+ T lymphocytes, and Monocytes. Because of their central role in regulating the immune response, depletion of CD4+ T cells renders the infected individual incapable of adequately responding to microorganisms otherwise inconsequential. Epidemiology, incidence and prevalence: New HIV infections affect predominantly young heterosexual women and homosexual men. While the mortality rates of AIDS related causes have decreased globally in recent years due to the use of highly active antiretroviral therapy (HAART) treatment, a vaccine remains an elusive goal. Treatment and curability: For those afflicted HIV infection remains a serious illness. Nonetheless, the use of advanced therapeutics have transformed a dire scenario into a chronic condition with near average life spans. When to apply those remedies appears to be as important as the remedies themselves. The high rate of HIV replication and the ability to generate variants are central to the viral survival strategy and major barriers to be overcome. Molecular mechanisms of infection: In this review, we assemble new details on the molecular events from the attachment of the virus, to the assembly and release of the viral progeny. Yet, much remains to be learned as understanding of the molecular mechanisms used in viral replication and the measures engaged in the evasion of immune surveillance will be important to develop effective interventions to address the global HIV pandemic.

The human body constitutes a balanced ecosystem of its own cells together with various microbes ("host-microbe ecosystem"). The transmission of HIV-1 and the progression of HIV disease in such an ecosystem are accompanied by de novo infection by other microbes or by activation of microbes that were present in the host in homeostatic equilibrium before HIV-1 infection. In recent years, data have accumulated on the interactions of these coinfecting microbes-viruses in particular-with HIV. Coinfecting viruses generate negative and positive signals that suppress or upregulate HIV-1. We suggest that the signals generated by these viruses may largely affect HIV transmission, pathogenesis, and evolution. The study of the mechanisms of HIV interaction with coinfecting viruses may indicate strategies to suppress positive signals, enhance negative signals, and lead to the development of new and original anti-HIV therapies.

Considering the fact that information on HIV/AIDS is a strategy for disease control, this project was planned to provide comprehensive information about HIV infection and AIDS to schoolteachers and their students. Previous analysis of adolescent students' knowledge of HIV/AIDS showed that they still have doubts about transmission, diagnosis, and…
African Americans are the most affected by HIV/AIDS. Both males and females continue to be disproportionately affected by HIV/AIDS. They are often drug users or participate in street/drug subculture. Recent weather disasters have required identification of knowledge, beliefs, conduct norms and behavior patterns that are HIV/AIDS risk factors for disaster survivors. This paper examines patterns of behavior and common practices related to HIV among disaster survivors.

The Ministry of Health coordinates and orients in Brazil all the activities concerning the acquired immunodeficiency syndrome which is officially designated as AIDS. The first AIDS' case registered in Brazil was, by retrospective diagnosis, in 1981 but it was in 1982 that the first two diagnosis in live patients were made. The incidence is very high in this country that is among the ones where the higher number of cases are being registered. The great majority of the Brazilian cases occurs in the cities and in direct proportion to the population index. The groups of risk are the same universally known and a comparative increase of heterosexual transmission is noted, chiefly due to the use of injectable drugs and bisexuality of the male partners. Another problem that is being increased is pediatric AIDS, with raising importance of perinatal transmission as well as the use of injectable drugs and precocious prostitution in adolescence. The transfusional and haemophilic AIDS have proportionally decreased due to the control of blood products. The control and the orientation activity of the Ministry of Health is directed to varied points such as: compulsory cases notification, cooperation between public and private sectors, preventive and sexual orientation, freely delivered medication and laboratory tests including sigilous tests, lay and technical personnel preparation, diversified informative and educational campaigns. Trial tests with anti-HIV vaccines have begun to be performed. Multiple Reference Centers were officially established by the administration. Among them is to be quoted the Hospital Universitário Gaffrée Guinle of Rio de Janeiro where the authors work. It is credited for its intensive activity and pioneerism. In this Institution special attention was due against discrimination of HIV-infected patients, to diagnosis, to anonymous and sigilous tests, to medical and psychological assistance, to myocardium involvement, to the virologic study of the

Parental illness and death due to human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) impose challenges to children's psychological adjustment. Positive psychology emphasizes individual's resilience in the face of adversity, trauma, and tragedy. Limited data are available regarding the factors that can cultivate resilience of children affected by HIV/AIDS. This study aims to examine the role of extracurricular interest in strengthening resilience among children affected by HIV/AIDS. Participants included 755 children orphaned by parental HIV/AIDS, 466 vulnerable children living with HIV-positive parent(s), and 404 comparison children from HIV-free families in the same community in rural China. The measures include extracurricular interest (i.e., reading, sports, music, painting, science, and playing chess) and indicators of psychological adjustment (i.e., depression, loneliness, and self-esteem). Having extracurricular interest was positively associated with self-esteem and negatively associated with depression and loneliness. Having extracurricular interest attenuated the negative effect of parental HIV/AIDS on children's self-esteem and loneliness, after controlling for children's age, gender, and family socioeconomic status. The findings underscore the importance of nurturing extracurricular interest and make available of such activities to promote resilience for children affected by HIV/AIDS in resource-limited settings.

The purpose of this pilot study was to illustrate international university students' knowledge of HIV and AIDS, attitudes towards HIV and AIDS and risk behaviours in relation to HIV and AIDS. Questionnaires were posted to 140 students, and 32 responded. Data were analysed statistically. The results indicated a fairly good knowledge level of HIV and AIDS. The majority of students were well aware of the general facts about HIV and AIDS, modes of transmission and main risk groups, and they were also aware of the universal precautions. The majority of students had positive attitudes towards persons with HIV and AIDS and were willing to care for them. The students identified well with risk behaviours. Most agreed that their knowledge level of HIV and AIDS did affect their risk behaviours, while others felt it was a matter of choice, personal attitude and practice. Choice is a determining factor for decisions made by students in relation to HIV and AIDS. Future research focusing on factors influencing these choices that put them at risk of contracting the HIV virus is recommended. Students also need to be enlightened on matters concerning symptoms of HIV and AIDS.

A great effort for developing AIDS vaccine has been carried out in the world, designed by various new ideas based on basic research information obtained in recent virology and immunology. Withall it, to obtain effective AIDS vaccine is considered skeptical. One of the reasons of its difficulty is a lack of experimental animals susceptible to HIV-1. In our laboratory, we have succeeded in developing chimeric SIV having 3' half of HIV-1 genome including env (SHIV), which is infectious to macaque monkeys. One of SHIVs has been proved nonpathogenic in monkeys from various aspects and it afforded protective immunity to monkeys against pathogenic SHIV challenge infection. Now, we are trying to develop anti-HIV live attenuated vaccines using the nonpathogenic SHIV as a starting material. In the history of virus vaccine, live attenuated vaccines have been proved most effective in measles and polio-myelitis. However, it is not clear whether nonpathogenic HIV exists or not. Futhermore, even if nonpathogenic HIV could be obtained, there is possibility that it will easily mutate to pathogenic one. Therefore, to develop live attenuated AIDS vaccine is considered dangerous. In this article, We will introduce our research on SHIV pathogenicity using monkeys and hypothesize possibility to obtain nonpathogenic HIV which is speculated from the origin and evolution of HIV/SIV. To clarify virulence and nonvirulence of HIV and to obtain nonpathogenic virus are not only applied research but also basic science to dissolve the fundemental question why HIV can induce the disease.

Nurses’ stigmatization of people living with HIV/AIDS hinders effective health care provisions for this sector of the population. Scientific literature on HIV/AIDS stigma has emphasized cognitive, individual, and interpersonal factors that are relevant to the understanding of the stigmatization process among health care professionals (e.g. a health care professional’s accuracy in knowledge of the workings of the virus, effectiveness of emotion management, degree of proximity to the stigmatized group, etc.). However, researchers have also examined the socio-structural factors underlying stigma, and religion has consequently emerged as a social phenomenon that may foster it. The role of religion among professional nurses who specifically service people living with HIV/AIDS remains understudied. Focusing on evidence-based literature, we discuss the relationship between religion and HIV/AIDS stigma, explore potential implications of this relationship for the nursing profession, and make recommendations for stigma-reducing interventions.

Social marketing techniques have been tested and proven useful within the health sector worldwide. In Fiji, social marketing was introduced in the early 1990s, and more rapidly during the last decade to improve national response to an increasing incidence of sexually transmitted infections (STIs) such as human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS). Given the limited amount of research in the area of program evaluation in Pacific Island Countries and Territories (PICTs), this study systematically analyzes five Fijian HIV/AIDS prevention programs through Andreasen's benchmark criteria, in order to identify gaps in program design that ultimately impact program effectiveness. Assessment results unveil some interesting trends regarding the focus and applications of past Fijian HIV/AIDS prevention programs in the past decade. This article discusses these findings and other valuable lessons for future HIV/AIDS prevention strategies in Fiji and elsewhere.

Background: This study was performed in response to the rapid propagation of HIV/AIDS across Iran and its status in this region. Accordingly, an evidence-based program is required to combat this disease. Objectives: The present study estimated the prevalence of HIV/AIDS in East Azerbaijan (population: 3,724,000). Materials and Methods: We created a database of all positive cases from 1987 to 2012. We also analyzed and described the epidemiological status of HIV/AIDS during a 25-year period by using SPSS. Results: In East Azerbaijan, 371 HIV/AIDS cases have been reported, i.e. 1 case per 10,000 population. The vast majority of reported cases (91%, n =338) were men, whereas only 9% (n = 33) were women. The mean age of patients was 30.8 ± 12.3 years. Unsafe drug injection (59%, n = 219) and sexual interaction (13%, n = 48) were the two major modes of HIV transmission. In addition, 7% (n = 25) of patients have been diagnosed with HIV, hepatitis B Virus, and hepatitis C virus simultaneously. Moreover, 60% (n = 205) of men were infected via drug injection, while 82% (n = 27) of women were infected via unprotected sexual interaction (P < 0.001). Conclusions: The results indicate a rapid increase in the number of HIV/AIDS cases in East Azerbaijan, necessitating immediate attention and strategies to combat the rapid spread of the disease. Development of provincial and national HIV/AIDS strategies demands more accurate and comprehensive HIV/AIDS surveillance. PMID:26468361

Lack of practical knowledge among home-based caregivers on human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS), anti-retroviral therapy (ART) and poor individual adherence to treatment are among the root causes of ineffective ART service delivery in Namibia. The purpose of our study was to investigate the knowledge among home-based caregivers in Namibia regarding HIV/AIDS. The study was a descriptive, cross-sectional one in which 89 participants completed a self-administered questionnaire to assess their knowledge of HIV/AIDS. Almost all (93%) of the respondents gave a correct definition of HIV. Over a tenth (11.3%) did not know that HIV decreases the body's ability to fight disease and 33.7% could not define AIDS. Almost all (98%) the home-based caregivers knew that HIV can be diagnosed only through a blood test and 91% mentioned that consistent and correct use of condoms during sexual intercourse protects one from HIV infection. Fewer than half (44%) of the respondents could indicate on-and-off fever as a symptom of AIDS and 16% mentioned that increased body weight is a sign of AIDS, which is incorrect. Although the knowledge of the caregivers on HIV/AIDS was above average in some aspects, there was still lack of knowledge on isolated issues such as AIDS definitions and signs and how HIV works. Training organisations in home-based care settings should emphasise the knowledge of AIDS definition and signs as well as of post-test counselling, consequence of poor adherence and facilities that issue anti-retroviral treatment.

Despite being simple eukaryotic organisms, the yeasts Saccharomyces cerevisiae and Schizosaccharomyces pombe have been widely used as a model to study human pathologies and the replication of human, animal, and plant viruses, as well as the function of individual viral proteins. The complete genome of S. cerevisiae was the first of eukaryotic origin to be sequenced and contains about 6,000 genes. More than 75% of the genes have an assigned function, while more than 40% share conserved sequences with known or predicted human genes. This strong homology has allowed the function of human orthologs to be unveiled starting from the data obtained in yeast. RNA plant viruses were the first to be studied in yeast. In this paper, we focus on the use of the yeast model to study the function of the proteins of human immunodeficiency virus type 1 (HIV-1) and the search for its cellular partners. This human retrovirus is the cause of AIDS. The WHO estimates that there are 33.4 million people worldwide living with HIV/AIDS, with 2.7 million new HIV infections per year and 2.0 million annual deaths due to AIDS. Current therapy is able to control the disease but there is no permanent cure or a vaccine. By using yeast, it is possible to dissect the function of some HIV-1 proteins and discover new cellular factors common to this simple cell and humans that may become potential therapeutic targets, leading to a long-lasting treatment for AIDS.

Neurological complications associated with HIV-1/AIDS are being recognized with a high frequency that parallels the increased number of AIDS cases. The early infiltration by HIV-1 into the nervous system can cause primary and/or secondary neurological complications. The most common neurocognitive disorder is AIDS Dementia Complex (ADC). In developing countries of Asia the three most opportunistic infections are tuberculosis (TB), cryptococcosis, and Pneumocystis carinii pneumonia. Therefore, it is expected that secondary neurological complications due to TB and cryptococcosis will be the most common cause of morbility and mortality in HIV-1/AIDS cases in China. Research of NeuroAIDS in China is necessary to understand the impact and the biology of HIV-1 in the nervous system. Future studies would include, the molecular epidemiology and the description of opportunistic infections associated to HIV-1; the neuropathological description of primary and secondary HIV-1 complications in different groups; the HIV-1 neurotropism and immune response studies for China's unique HIV-1 strains and recombinant forms derived from the nervous system, including experimental models such as the use of transgenic rats; and the study of potential resistant virus, primarily when the anti-retroviral therapy (ART) has not full access in the brain.

Objective To review the past 10 years of published research on human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) in the United States, including psychosocial and psychiatric risk factors, epidemiology, biology, neurocognitive and psychiatric sequelae, disclosure issues, prevention strategies, and biological and behavioral treatments. Method Researchers reviewed the English-language literature with a focus on child and adolescent risk factors associated with HIV/AIDS, prevention, and treatment. Results Substantial scientific advances have occurred over the past two decades leading to decreased morbidity and mortality in the United States from AIDS-related opportunistic infections. At the same time, rates of HIV infection are increasing in teenagers, young women, and minorities, and growing numbers of youths are living with an infected family member. Understanding HIV risk behavior requires a broad theoretical framework. Comprehensive HIV prevention programs have led to reduced risk behavior among HIV-affected youths and teens at risk of infection. Biological and behavioral treatments of HIV infection continue to evolve and have led to longer life span, improved quality of life, and fewer psychiatric problems. Conclusions HIV/AIDS has significant mental health implications, and psychiatry can play a critical role in curbing the epidemic. With minimal effort, mental health professionals can adapt and apply the strategies that they use to treat psychiatric symptoms to prevent HIV transmission behaviors. PMID:16034275

AIDS denialists offer false hope to people living with HIV/AIDS by claiming that HIV is harmless and that AIDS can be cured with natural remedies. The current study examined the prevalence of AIDS denialism beliefs and their association to health-related outcomes among people living with HIV/AIDS. Confidential surveys and unannounced pill counts were collected from a predominantly middle aged and African American convenience sample of 266 men and 77 women living with HIV/AIDS. One in five participants stated that there is no proof that HIV causes AIDS and that HIV treatments do more harm than good. AIDS denialism beliefs were more often endorsed by people who more frequently used the internet after controlling for confounds. Believing that there is a debate among scientists about whether HIV causes AIDS was related to refusing HIV treatments and poorer health outcomes. AIDS denialism beliefs may be common among people living with HIV/AIDS and such beliefs are associated with poor health outcomes. PMID:20571892
Human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) affects economic growths by reducing the human capitals are among the most poorly understood aspect of the AIDS epidemic. This article analyzes the effects of the prevalence of HIV and full-blown AIDS on a country's human capitals and economic growths. Using a fixed effect model for panel data 1990-2010 from the Asia, I explored the dynamic relationships among HIV/AIDS, economic growths, and human capitals within countries over time. The econometric effects concerned that HIV/AIDS plays an important role in the field of economic growths and it is measured as a change in real gross domestic product (GDP) per capita and human capitals. The modeling results for the Asian countries indicates HIV/AIDS prevalence that has a hurtful effect on GDP per capita by reducing human capitals within countries over time.

This report describes the partnership between the schools of nursing at the University of California San Francisco and the University of Puerto Rico to address the need for nursing research on HIV/AIDS health disparities. The partnership led to the creation of the Nursing Research Center on HIV/AIDS Health Disparities with funding from the National Institutes of Health/National Institute of Nursing Research. We provide background information on the disproportionate impact of the HIV/AIDS epidemic on racial and ethnic minorities, describe the major predictors of health disparities in persons at risk for or diagnosed with HIV/AIDS using the Outcomes Model for Health Care Research, and outline the major components of the Nursing Research Center. The center's goal is to improve health outcomes for people living with and affected by HIV/AIDS by enhancing the knowledge base for HIV/AIDS care.
Background Recent data have shown that HTLV-1 is prevalent among HIV positive patients in Mozambique, although the impact of HTLV-1 infection on HIV disease progression remains controversial. Our aim was to determine the phenotypic profile of T lymphocytes subsets among Mozambican patients co-infected by HIV and HTLV-1. Methods We enrolled 29 patients co-infected by HTLV-1 and HIV (co-infected), 59 patients mono-infected by HIV (HIV) and 16 healthy controls (HC), respectively. For phenotypic analysis, cells were stained with the following fluorochrome-labeled anti-human monoclonal antibodies CD4-APC, CD8-PerCP, CD25-PE, CD62L-FITC, CD45RA-FITC. CD45RO-PE, CD38-PE; being analysed by four-colour flow cytometry. Results We initially found that CD4+ T cell counts were significantly higher in co-infected, as compared to HIV groups. Moreover, CD4+ T Lymphocytes from co-infected patients presented significantly higher levels of CD45RO and CD25, but lower levels of CD45RA and CD62L, strongly indicating that CD4+ T cells are more activated under HTLV-1 plus HIV co-infection. Conclusion Our data indicate that HTLV-1/HIV co-infected patients progress with higher CD4+ T cell counts and higher levels of activation markers. In this context, it is conceivable that in co-infected individuals, these higher levels of activation may account for a faster progression to AIDS. PMID:20028500
As the treatment and management of HIV/AIDS continues to evolve with new scientific breakthroughs, treatment discoveries, and management challenges, it is difficult for people living with HIV/AIDS and those who care for them to keep up with the latest information on HIV/AIDS screening and testing, prevention, treatment, and research. The National Library of Medicine (NLM), of the National Institutes of Health, has a wealth of health information resources freely available on the Internet to address these needs.

Although there has been research focused on the disabling consequences of HIV/AIDS, there has been very little documented information about HIV/AIDS for individuals with disability prior to infection. There is evidence to suggest that people with disabilities face inequalities in accessing health information and services. The aim of this study was to explore whether disabled and non-disabled young adults in Swaziland perceive HIV/AIDS similarly. A qualitative study using focus-group discussions was conducted. Four focus groups were conducted with a total of 56 non-disabled adults (aged 16-29 years) and four focus groups were conducted with a total of 32 adults with either a physical or hearing disability (aged 18-32 years). The focus-group schedule explored knowledge about HIV/AIDS, personal risk and experiences of health-seeking practices. Information and awareness about HIV/AIDS was good in both rural and urban areas among the non-disabled participants, who obtained their information from a wide range of sources. In contrast, participants with disability, who obtained information about HIV/AIDS from a limited range of sources, lacked knowledge about HIV/AIDS and were misinformed about modes of transmission. Women with disabilities described experiences of sexual exploitation and abuse, which was perceived to be higher among disabled women than their non-disabled peers; they felt this was because disabled women were perceived to be 'free' from the HIV virus by non-disabled men. Further research is necessary to enable HIV/AIDS programmes to address the specific needs of people with disabilities.

The authors make out a statement about HIV infection in French Polynesia at the date of 1991 December 31. 96 cases all together of seropositive and AIDS infected people were recorded. These patients are young generally (78 p.c. between 21 and 40 years old) sexually contaminated (72 out of 96) and live in Tahiti island (94 p.c.). Sex-ratio is 2.8 male/1 female. Among them, we noted 55 p.c. of Europeans, 38 p.c. of Polynesians and 7 p.c. of Asiatic people. Epidemiological monitoring of the infection was made easy because of a set of laws and possibilities of detection highly favourable. Progress of the infection is constant, with 20 new cases detected each year with a prevalence of 150 cases of AIDS per 1 million of inhabitants, French Polynesia could be classified as the 5th or 6th region of France as far as the importance of the disease. Clinical, biological and epidemiological taking of charge of patients is detailed as well as the prevention campaign.

Anglo American is one of the world's leading mining companies. With operations in over 50 countries and approximately 200 000 permanent employees, its operating profit in 2006 was US$9.8 billion. As well as having financial goals, Anglo American is committed to sustainable development. One of its five sustainable development principles is to 'create meaningful employment in safe, healthy environments'. Its HIV/AIDS programme is part of this effort. Beginning in the mid-1980s with the appointment of an AIDS Education Advisor, the programme was formalized in the early 1990s, and has gained international recognition for its effectiveness and scope. This paper provides an overview of the Anglo American HIV/AIDS programme in southern Africa. Part one outlines the context in which the company works and its reasons for tackling the virus. Part two describes the workplace programme, with a specific focus on Anglo Coal as an example of best practice within the group. Part three looks at the community programme, and the final section discusses the lessons learned.

The population of Middle Eastern immigrants in the US has been increasing dramatically over the past 30 years, growing from 200,000 in 1970 to 1.5 million in 2000. These immigrants and their descendants constitute an important new population of interest for public health and other social programmes. With this addition to the cultural diversity of American society, it is important for healthcare programmes to be responsive to the unique cultural needs of those of Middle Eastern origin and to include them in healthcare curricula. This need is particularly imperative for human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) intervention programmes, where the reduction of risky behaviours is essential to controlling the epidemic. When Middle Easterners emigrate to the US they must adjust to the American culture, which leads to preservation of some aspects of their culture and adjustment of behaviors to match American customs. This article aims to present sociocultural factors of HIV risk behaviours that are specific to Middle Eastern culture. The article also provides recommendations for HIV/AIDS-culturally appropriate intervention programmes.

African American women, including adolescents and adults, are disproportionately affected by the transmission of Human Immunodeficiency Virus (HIV) and Acquired Immunodeficiency Syndrome (AIDS). HIV/AID is a health disparity issue for African American females in comparison to other ethnic groups. According to data acquired from 33 states in 2005, 64% of women who have HIV/ AIDS are African American women. It is estimated that during 2001-2004, 61% of African Americans under the age of 25 had been living with HIV/AIDS. This article is an analytical review of the literature emphasizing sexual assertiveness of African American women and the gap that exists in research literature on this population. The multifaceted model of HIV risk posits that an interpersonal predictor of risky sexual behavior is sexual assertiveness. The critical themes extracted from a review of the literature reveal the following: (a) sexual assertiveness is related to HIV risk in women, (b) sexual assertiveness and sexual communication are related, and (c) women with low sexual assertiveness are at increased risk of HIV As a result of this comprehensive literature, future research studies need to use models in validating sexual assertiveness interventions in reducing the risk of HIV/AIDS in African American women. HIV/AIDs prevention interventions or future studies need to target reducing the risk factors of HIV/AIDS of African Americans focusing on gender and culture-specific strategies.

Given changes in the faces of AIDS over the last decade, it is crucial that disparities in health and access to healthcare are addressed. An Internet-based GIS was developed using ESRI's Arc Internet Map Server (Arc IMS) to provide users with a suite of tools to interact with geographic data and conduct spatial analyses related to the characteristics that promote or impede the provision of HIV-related services. Internet Mapping allows those engaged in local decision-making to: (1) geographically visualize information via the Internet; (2) Assess the relationship between the distribution of HIV services and spatially referenced socio-economic data; and (3) generate "what if" scenarios" that may direct the allocation of healthcare resources.

Background HIV infection among substance abusers is a growing concern in the United States. Little research, however, has examined the provision of HIV/AIDS services in substance abuse treatment programs. Methods This study examines the provision of onsite HIV/AIDS services in a nationally representative sample of 345 privately funded substance abuse treatment programs. Data were collected via face-to-face interviews with administrators and clinical directors of treatment programs in 2007–2008. Results Results show that larger programs and programs with a higher percentage of both African American and injection drug using (IDU) patients were more likely to offer onsite HIV/AIDS support groups and a dedicated HIV/AIDS treatment track. Multinomial logistic regression reveals that the odds of offering onsite HIV testing services were higher for hospital based programs, programs providing medical services onsite, and programs with higher percentages of African American patients, relative to the odds of offering no HIV testing or referring patients to an external provider for HIV testing services. The odds of providing onsite testing were lower for outpatient-only treatment programs, relative to the odds of offering no HIV testing or referring patients to an external provider for HIV testing services. Conclusions Our findings highlight critical barriers to the adoption of onsite HIV/AIDS services and suggest treatment programs are missing the opportunity to significantly impact HIV-related health outcomes.

Poxvirus vector Modified Vaccinia Virus Ankara (MVA) expressing HIV-1 Env, Gag, Pol and Nef antigens from clade B (termed MVA-B) is a promising HIV/AIDS vaccine candidate, as confirmed from results obtained in a prophylactic phase I clinical trial in humans. To improve the immunogenicity elicited by MVA-B, we have generated and characterized the innate immune sensing and the in vivo immunogenicity profile of a vector with a double deletion in two vaccinia virus (VACV) genes (C6L and K7R) coding for inhibitors of interferon (IFN) signaling pathways. The innate immune signals elicited by MVA-B deletion mutants (MVA-B ΔC6L and MVA-B ΔC6L/K7R) in human macrophages and monocyte-derived dendritic cells (moDCs) showed an up-regulation of the expression of IFN-β, IFN-α/β-inducible genes, TNF-α, and other cytokines and chemokines. A DNA prime/MVA boost immunization protocol in mice revealed that these MVA-B deletion mutants were able to improve the magnitude and quality of HIV-1-specific CD4+ and CD8+ T cell adaptive and memory immune responses, which were mostly mediated by CD8+ T cells of an effector phenotype, with MVA-B ΔC6L/K7R being the most immunogenic virus recombinant. CD4+ T cell responses were mainly directed against Env, while GPN-specific CD8+ T cell responses were induced preferentially by the MVA-B deletion mutants. Furthermore, antibody levels to Env in the memory phase were slightly enhanced by the MVA-B deletion mutants compared to the parental MVA-B. These findings revealed that double deletion of VACV genes that act blocking intracellularly the IFN signaling pathway confers an immunological benefit, inducing innate immune responses and increases in the magnitude, quality and durability of the HIV-1-specific T cell immune responses. Our observations highlighted the immunomodulatory role of the VACV genes C6L and K7R, and that targeting common pathways, like IRF3/IFN-β signaling, could be a general strategy to improve the immunogenicity of poxvirus

The pharmacokinetics and safety of hyperimmune anti-human immunodeficiency virus (HIV) intravenous immunoglobulin (HIVIG) were evaluated in the first 28 maternal-infant pairs enrolled in a randomized, intravenous immunoglobulin (IVIG)-controlled trial of HIVIG maternal-infant HIV transmission prophylaxis. Using 200 mg/kg, mean half-life and volume of distribution (Vd) in women were 15 days and 72 mL/kg, respectively, after one and 32 days and 154 mL/kg after three monthly infusions, with stable 4 mL/kg/day clearance. Transplacental passage occurred. Newborn single-dose half-life, Vd, and clearance were 30 days, 143 mL/kg, and 4 mL/kg/day, respectively. HIVIG rapidly cleared maternal serum immune complex-dissociated p24 antigen, and plasma HIV-1 RNA levels were stable. Mild to moderate adverse clinical effects occurred in 2 of 103 maternal and 2 of 25 infant infusions. No adverse hematologic, blood chemistry, or immunologic effects were seen. HIVIG is well-tolerated in HIV-infected pregnant women and their newborns, clears antigenemia, crosses the placenta, and exhibits pharmacokinetics similar to those of other immunoglobulin preparations.

In South Africa, the HIV&AIDS education policy documents indicate opportunities for integration across disciplines/subjects. There are different interpretations of integration/inclusion and mainstreaming HIV&AIDS education, and numerous levels of integration. Integration ensures that learners experience the disciplines/subjects as being linked and related, and integration is required to support and expand the learners' opportunities to attain skills, acquire knowledge and develop attitudes and values across the curriculum. This study makes use of self-study methodology where I, a teacher educator, aim to improve my practice through including HIV&AIDS statistics in Mathematics Education. This article focuses on how I used HIV&AIDS statistics to facilitate pre-service teacher reflection and introduce them to integration of HIV&AIDS education across the curriculum. After pre-service teachers were provided with HIV statistics, they drew a pie chart which graphically illustrated the situation and reflected on issues relating to HIV&AIDS. Three themes emerged from the analysis of their reflections. The themes relate to the need for further HIV&AIDS education, the changing pastoral role of teachers and the changing context of teaching. This information indicates that the use of statistics is an appropriate means of initiating the integration of HIV&AIDS education into the academic curriculum.

One of the current focuses in HIV/AIDS research is to develop a novel therapeutic strategy that can provide a life-long remission of HIV/AIDS without daily drug treatment and, ultimately, a cure for HIV/AIDS. Hematopoietic stem cell-based anti-HIV gene therapy aims to reconstitute the patient immune system by transplantation of genetically engineered hematopoietic stem cells with anti-HIV genes. Hematopoietic stem cells can self-renew, proliferate and differentiate into mature immune cells. In theory, anti-HIV gene-modified hematopoietic stem cells can continuously provide HIV-resistant immune cells throughout the life of a patient. Therefore, hematopoietic stem cell-based anti-HIV gene therapy has a great potential to provide a life-long remission of HIV/AIDS by a single treatment. Here, we provide a comprehensive review of the recent progress of developing anti-HIV genes, genetic modification of hematopoietic stem progenitor cells, engraftment and reconstitution of anti-HIV gene-modified immune cells, HIV inhibition in in vitro and in vivo animal models, and in human clinical trials.

This study sought to establish whether there were measurable differences in the level of knowledge about HIV/AIDS between hearing individuals and individuals who identified themselves as deaf sign language users in Swaziland. A cross-sectional survey of 191 rural and urban hearing and deaf adults was undertaken in Swaziland in December 2003. A structured questionnaire was administered, seeking to establish whether there were statistically significant differences between hearing and deaf populations in their level of knowledge about HIV/AIDS symptoms, transmission and prevention, as well as differences in sources of information about HIV/AIDS. Additional questions were asked regarding whether there were differences in accessibility of HIV testing services and HIV/AIDS-related healthcare for the two groups. Significant differences in levels of knowledge about HIV/AIDS were identified between the hearing and deaf respondents. The deaf population was significantly more likely (P<0.05) to believe in incorrect modes of HIV transmission (e.g. hugging and airborne transmission) and HIV prevention (e.g. avoiding sharing utensils and eating healthy foods). Almost all of the deaf respondents (99%) reported difficulties in communicating with healthcare facility staff, which may result in less use of HIV voluntary counseling and testing services. This paper reports the results of this study, and discusses the need for targeted HIV/AIDS education campaigns and improved accessibility in healthcare facilities for deaf sign language users in countries such as Swaziland.

the province during the study period, and CRF01-AE and CRF07-BC intersubtype recombinant forms were predominant; however, a declining trend in the proportion of HIV-1 CRF01-AE recombinant virus and a significant rise in the proportion of HIV-1 CRF07-BC recombinant virus were observed. Over 90% HIV inhibition was found in all cases receiving antiretroviral therapy during the period from 2011 to 2015, indicating a low prevalence of HIV drug resistance. Conclusions: An increasing trend is still observed in the HIV/AIDS epidemics in Fujian Province, southeastern China. However, the epidemiological pattern of HIV/AIDS has recently changed in the province, and effective control interventions targeting the shift in the epidemiological features of HIV/AIDS should therefore be implemented to control the spread of the epidemic.

Schools play a significant role in conveying essential knowledge, skills and attitudes about HIV and AIDS to millions of learners, and are therefore at the forefront of addressing the HIV/AIDS pandemic. This has resulted in a shift in HIV/AIDS research to focus on the crucial role of teachers in HIV prevention. This paper explores the influence of teachers' subjectivities and emotionality on their teaching about HIV/AIDS. The paper draws on qualitative, narrative data gathered from five teachers teaching in a midlands town in KwaZulu-Natal, South Africa. It finds that teachers' subject positions play a significant role in presenting compassionate, supportive and knowledgeable subjectivities in the classroom; and that their positive and negative emotions pivotally influence their teaching about HIV/AIDS. We argue that it is vital to consider how teachers position themselves, as this is intricately linked with their teaching about HIV/AIDS, and we draw attention to teaching about HIV/AIDS as an emotional practice.

Adolescents are critical to efforts to end the AIDS epidemic. Few national AIDS strategies explicitly program for children in their second decade of life. Adolescents (aged 10-19 years) are therefore largely invisible in global, regional, and country HIV and AIDS reports making it difficult to assess progress in this population. We have unprecedented knowledge to guide investment towards greater impact on HIV prevention, treatment, and care in adolescents, but it has not been applied to reach those most vulnerable and optimize efficiency and scale. The cost of this is increasing AIDS-related deaths and largely unchanged levels of new HIV infections in adolescents. An AIDS-free generation will remain out of reach if the global community does not prioritize adolescents. National AIDS responses must be accountable to adolescents, invest in strengthening and monitoring protective and supportive laws and policies and access for adolescents to high impact HIV interventions.
Prevalence and pattern of neuropsychological impairment in human immunodeficiency virus-infected/acquired immunodeficiency syndrome (HIV/AIDS) patients across pre- and post-highly active antiretroviral therapy eras: a combined study of two cohorts.
Cysique, Lucette A; Maruff, Paul; Brew, Bruce J
The objective of this study was to assess the prevalence and pattern of neuropsychological impairment in cohorts of human immunodeficiency virus (HIV)-infected individuals across pre- and post-HAART (highly active antiretroviral therapy) eras. Two cohorts of HIV-infected individuals attending tertiary referral hospital outpatient clinics were studied. The cohorts represented two eras of antiretroviral medication: monotherapy (n = 51) and HAART (n = 90). Each was compared in nine neuropsychological domains in regard to the prevalence as well as pattern of neuropsychological impairment. Because the authors intended to characterize the prevalence and pattern of neuropsychological deficits in nondemented advanced HIV-infected individuals, patients with a current diagnosis of acquired immunodeficiency syndrome (AIDS) dementia complex were not included. The prevalence of impairment was not significantly different across pre-HAART and HAART eras using a standard criterion to define impairment: -2 SD in two neuropsychological measures (41.1%/38.8%). Prevalence of deficits was not significantly reduced in patients with undetectable plasma viral load. The pattern of neuropsychological impairment was different across pre-HAART and HAART eras, with an improvement in attention, verbal fluency, visuoconstruction deficits, but a deterioration in learning efficiency and complex attention. This change remained even in patients with an undetectable plasma viral load, although the severity was partially diminished. Neuropsychological deficits remain common in the HAART era, essentially uninfluenced by HAART. The finding that some neuropsychological functions are improving while other are deteriorating indicates that these deficits do not reflect "burnt out" damage but rather that there is an active intracerebral process occurring, the nature of which is still to be determined.

Electromagnetic signals of low frequency have been shown to be durably produced in aqueous dilutions of the Human Imunodeficiency Virus DNA. In vivo, HIV DNA signals are detected only in patients previously treated by antiretroviral therapy and having no detectable viral RNA copies in their blood. We suggest that the treatment of AIDS patients pushes the virus towards a new mode of replication implying only DNA, thus forming a reservoir insensitive to retroviral inhibitors. Implications for new approaches aimed at eradicating HIV infection are discussed.

The Tuskegee study of untreated syphilis in black males caused distrust by blacks of the public health system that has implications for Acquired Immune Deficiency Syndrome (AIDS) and Human Immunodeficiency Virus (HIV) studies.

Background The prevalence of HIV/hepatitis co-infection in sub-Saharan Africa is not well documented, while both HIV and HBV are endemic in this area. Objective The aim of this study is to determine the seroprevalence of HBV and HCV virus in HIV-infected subjects in the Gambia. Methods Plasma samples from HIV infected patients (190 individuals with clinically defined AIDS and 382 individuals without AIDS) were tested retrospectively for the presence of HBV sero-markers and for serum HBV DNA, screened for HCV infection by testing for anti-HCV antibody and HCV RNA. Results HBsAg prevalence in HIV-positive individuals is 12.2%. HIV/HBV co-infected individuals with CD4 count of <200 cells uL-1 have a higher HBV DNA viral load than patients with higher CD4 count (log 4.0 vs. log 2.0 DNA copies/ml, p < 0.05). Males (OR = 1.8, 95% CI: 1.0, 3.2) were more likely to be HBsAg positive than female. HCV seroprevalence was 0.9% in HIV-positive individuals. Conclusion The prevalence of HBsAg carriage in HIV- infected Gambians is similar to that obtained in the general population. However co-infected individuals with reduced CD4 levels, indicative of AIDS had higher prevalence of HBeAg retention and elevated HBV DNA levels compared to non-AIDS patients with higher CD4 count.

The immune response against HIV does not result in complete viral clearance. Recent interventions have focused on novel strategies to modify human anti-HIV immunity. Active vaccination of patients with HIV infection (vaccine therapy) safely alters the immune repertoire against HIV. This unique approach will provide insight into the immunoregulatory consequences of HIV-specific innate and adaptive immune responses, and hopefully define the immunological Achilles heel of HIV. Once defined, researchers, aided by current biotechnological techniques, can rationally design future vaccines and immune based therapeutic products.

Although community-based research (CBR) is gaining popularity, especially within the field of HIV/AIDS research, there is a paucity of practical models or frameworks designed to guide researchers and community members. Within the present paper the author presents a ten-stage model of conducting CBR that emerged from two HIV/AIDS CBR studies that were conducted in Alberta, Canada. The main strengths and challenges to conducting HIV/AIDS CBR are also explored. Living a life with HIV has changed dramatically over the past few decades. There have been notable improvements in medical technology and treatment, resulting in increased quality and duration of life (Volberding, 1998; Wong-Staal, 1997) as well as improvements in psychosocial interventions leading to improved mental health services (Grinstead & Van Der Straten, 2000; Hoffman, 1996; Sarwer & Crawford, 1994; Schaffner, 1994). Perhaps most significant has been the astonishing community rallying and social support networks that have occurred among individuals living with HIV and AIDS (Roy & Cain, 2001). People living with HIV and AIDS have demonstrated their resilience and positive outlooks through developing a multitude of community connections and projects. These organizational groups have engaged in HIV peer counselling at community-based organizations, fund raising programs, board involvement in community agency organizations and HIV/AIDS national committees, as well as volunteer work in many settings. There has also been a recent focus on CBR, which includes having individuals living with HIV and AIDS, people vulnerable to HIV infection or other stakeholders in HIV/AIDS issues become partners in research projects with academic or trained researchers (Health Canada, 2002).

One of the most intriguing aspects concerning the pathogenesis of AIDS is the long period of latency of the HIV in human cells, not causing any cytopatic effect in some and, on the other hand, causing cell destruction, at short periods, in others. The various agents and the mechanisms they adopt to reactivate the latente HIV, were described. Also the frequent epidemiological observation on the presence of both such agents and the HIV in AIDS patients allowed the authors to speculate on the probable important role of a cohort of co-factors which determine the destiny of such individuals. Special considerations were made in respect to the hepatitis B virus, cytomegalovirus, herpesviruses (HHV-1, e and 6), EB virus, HTLV-1 and 2 retroviruses, group B arbovirus Maguary, malaria and other endemic infectious diseases which victimize millions of Brazilians. Accepting the importance of such co-factors acting on the viral gens that regulate the HIV expression in the host cell, it was speculated on the possible role of vaccines, such as the hepatitis B vaccine, and some antiviral drugs which could be useful in the indirect prevention of AIDS-disease in both HIV-carriers and those practising AIDS-high-risk-activities.

The success in the development of anti-retroviral therapies (HAART) that contain human immunodeficiency virus type 1 (HIV-1) infection is challenged by the cost of this lifelong therapy and by its toxicity. Immune-based therapeutic strategies that boost the immune response against HIV-1 proteins or protein subunits have been recently proposed to control virus replication in order to provide protection from disease development, reduce virus transmission, and help limit the use of anti-retroviral treatments. HIV-1 matrix protein p17 is a structural protein that is critically involved in most stages of the life cycle of the retrovirus. Besides its well established role in the virus life cycle, increasing evidence suggests that p17 may also be active extracellularly in deregulating biological activities of many different immune cells that are directly or indirectly involved in AIDS pathogenesis. Thus, p17 might represent a promising target for developing a therapeutic vaccine as a contribution to combating AIDS. In this article we review the biological characteristics of HIV-1 matrix protein p17 and we describe why a synthetic peptide representative of the p17 functional epitope may work as a vaccine molecule capable of inducing anti-p17 neutralizing response against p17 derived from divergent HIV-1 strains.

Background Human Immunodeficiency Virus and Acquired Immunodeficiency Syndrome (HIV and AIDS) constitutes one of the major challenges to development worldwide. Actions taken by employers of labour against staff or applicants living with HIV have great impacts in the labour force and in the fight to mitigate the impact of the disease condition. In Nigeria, there's paucity of documented work about employers of labour's behavioural intentions when they are faced with staff/applicant living with the virus. This study explored the behavioural antecedents and intentions of employers of labour in Ibadan North Local Government Area, Oyo state, Nigeria. Methods The study was cross-sectional survey in design. A multistage sampling technique was used to select 400 study respondents (38 public and 362 private sectors) for interview. The instrument for data collection was a pre-tested semi–structured questionnaire. Attitude was categorised as negative (score ≤ 54) and positive (score ≥55). Data were analysed and presented using descriptive and inferential statistics. Results There were more males (68.2%) respondents than females (31.8%). A large majority, 79.0%, in the public sector (PuS) and 72.9% in the private sector (PrS) knew that an infected healthy looking person could harbour and transmit HIV to others. A majority, 80.0%, of which 2.3% with no formal education, 1.0% primary education, 13.5% high school education, 41.5% bachelor, 21.0% postgraduate and 0.8% with other qualifications were of the view that workers infected with HIV should not be sacked. Slightly less than half (48.0%) would keep their staff's HIV status secret while more than half, 57.0%, would not recruit a PLWHA. More PrS respondents (47.8%) claimed to have ever organised HIV/AIDS-related educational programmes for staff than PuS (42.1%) (p<0.05). Almost equal respondents (PuS 36.8%) and (PrS 36.2%) would require mandatory test for HIV before employment. Only 1.8% (PuS) and 6% (PrS) reported that

Tobacco smoking has many adverse health consequences. Patients with human immunodeficiency virus (HIV) infection smoke at very high rates, and many of the comorbidities associated with smoking in the general population are more prevalent in this population. It is likely that a combination of higher smoking rates along with an altered response to cigarette smoke throughout the body in persons with HIV infection leads to increased rates of the known conditions related to smoking. Several AIDS-defining conditions associated with smoking have been reviewed elsewhere. This review aims to summarize the data on non-AIDS-related health consequences of smoking in the HIV-infected population and explore evidence for the potential compounding effects on chronic systemic inflammation due to HIV infection and smoking.

Worldwide, there is a consensus that parents must be involved in children's HIV/AIDS education. However, there is little evidence that speaks to this advocacy for improving adolescent health. This study developed and tested four hypotheses about (i) the relationship between parents' and adolescents' knowledge of HIV/AIDS transmission routes and prevention strategies conditional upon (ii) parents' gender, (iii) communication about sexuality, and (iv) the parent-adolescent education gap. The sample consisted of 306 parent-adolescent dyads from the 2002 Cameroon Family and Health Survey. Adolescents were aged 12-19 years. Overall, fifteen items about HIV/AIDS transmission routes and prevention strategies were analysed. Descriptive results showed that parents fared better than adolescents regardless of the AIDS fact considered. An exception was the correct use of condoms (parents 57% vs adolescents 61%). The generation gap probably explains this result: parents are more conservative, reluctant and distant from condoms compared with adolescents, who are more receptive and open to discussing sex with peers. Multivariate ordered logistic regressions showed a significant positive effect of parents' HIV/AIDS knowledge on adolescents' HIV/AIDS knowledge, thus supporting the main hypothesis of direct parental influences. Parent-adolescent communication about sexuality showed positive and significant effects on adolescents' HIV/AIDS knowledge, suggesting an 'enhancing effect' when combined with the effect of parents' HIV/AIDS knowledge. Against the background that parents in sub-Saharan Africa do not teach their children about sexuality, the study demonstrated that families can play an important role in HIV/AIDS education. These findings have major implications for HIV/AIDS interventions involving adolescents, parents or both, in fostering accurate HIV/AIDS knowledge among adolescents, which could lead to protective sexual behaviours.

Progress in advancing research on the pathophysiology, prevention, treatment, and impact of human immunodeficiency virus (HIV) is threatened by the decaying purchasing power of National Institutes of Health (NIH) dollars. A working group of the NIH Office of AIDS Research Advisory Council was charged by the NIH Director with developing a focused and concise blueprint to guide the use of limited funding over the next few years. Science priorities outlined by the working group and reported here are intended to maximally address individuals, groups, and settings most affected by the epidemic, and to redress shortcomings in realizing population-level HIV prevention, treatment, and eradication goals. Optimizing these priorities requires that traditional silos--defined by topic focus and by scientific discipline--be dissolved and that structural issues affecting the pipeline of new investigators and the ability of the Office of AIDS Research to fulfill its role of steward of the NIH HIV/AIDS research program be directly addressed.

HIV-related stigma has a major impact on quality of life and health among people living with HIV and AIDS (PLWHA). This study examines demographic, mental health, behavioral, contextual, and HIV care-related correlates of HIV stigma among 503 substance abusing PLWHA. Stigma was measured with the HIV Internalized Stigma Measure which has four subscales: stereotypes about HIV, self-acceptance, disclosure concerns, and social relationships. Severe substance dependence (55.3%) and depression (54.7%) were associated with higher HIV stigma across all domains. 49.9% of the sample reported antiretroviral (ARV) medication diversion (the unlawful sale and trading of ARV medications); diverters endorsed significantly higher stigma related to disclosure. 54.1% of the sample reported ≥95% ARV adherence; these individuals reported significantly lower stigma for self-acceptance, disclosure, and social relationships. Multivariate linear regression showed that depression and social support demonstrated significant main effects across stigma domains. Findings suggest that interventions to decrease HIV related stigma may be an important component of initiatives to increase engagement in HIV care.

Although several studies have been conducted to assess dentists' knowledge of and attitudes towards human immunodeficiency virus (HIV)/acquired immune-deficiency syndrome (AIDS), few have targeted dental assistants. The main aims of this study were to assess the knowledge of and attitudes towards HIV/AIDS among dental assistants in Kuwait and to compare the knowledge and attitudes of dental assistants at Kuwait University Dental Center (KUDC) with those of dental assistants in Ministry of Health (MoH) hospitals. The secondary objective was to determine if any intervention was needed to provide more information to dental assistants on HIV/AIDS. A cross-sectional study was conducted by distributing questionnaires. The study sample included 85 dental assistants from each of KUDC and the MoH. The questionnaire included questions to assess the assistants' knowledge and attitude towards HIV/AIDS. Statistical data analysis was conducted using SPSS 20.0. Qualitative data were analysed using the Pearson chi-square text for any association or the Z-test for proportion to test the significance of differences. A total of 167 questionnaires were completed, returned and analysed. KUDC dental assistants were found to have significantly more knowledge about HIV/AIDS than their MoH counterparts, whereas the assistants at the MoH clinics displayed a more positive attitude towards patients with HIV/AIDS (P < 0.05). Although dental assistants at KUDC were more knowledgeable than those at the MoH clinics, there are still some misconceptions that need to be addressed, in addition to the negative attitudes displayed by some of the respondents. It would therefore be beneficial to increase awareness about HIV/AIDS patients through lectures, seminars and workshops targeting dental assistants.

The prospects for online social networks as sites of information-gathering and affiliation for persons with AIDS and others concerned about HIV/AIDS not only represent the latest development in a trend toward circumventing traditional media and official information sources, but also may offer hope for a revitalization of HIV/AIDS discourse in the public sphere. This article provides an overview of three decades of information-seeking on the pandemic and its social and personal implications, as well as case studies of three examples of social networking surrounding HIV/AIDS. It finds preliminary evidence of the formation of strong and weak ties as described in Social Network Theory and suggests that the online accumulation of social capital by opinion leaders could facilitate dissemination of messages on HIV/AIDS awareness and testing.

As a field of inquiry, postcolonial health communication seeks to apprehend processes implicated in the construction of "primitive" versus "modern" with respect to issues of health. In the case of HIV/AIDS, the sociocultural representations of the disease have a profound impact on how the disease is configured medically and symbolically in dominant cultural imagination. Postcolonial constructions of disease are mobilized around the political and economic interests of the dominant power structures in global spaces. In this article, a thematic analysis of the constructions of HIV/AIDS in India in the mainstream U.S. news media was conducted. A corpus of news articles from the Lexis-Nexis database was created with the keywords "HIV," "AIDS," and "India." Three themes emerged from the study: (a) India as a site of biomedical control; (b) the economic logics of HIV/AIDS; and (c) AIDS, development, and the "Third World."

This article explores the relevance of international human rights law in the response to the HIV/AIDS epidemic at national and international levels. Public health advocates can use arguments based on this body of law to promote responses to HIV/AIDS that reflect sound public health principles and documented best practice. Development assistance is increasingly linked to rights-based approaches, such as participatory processes, and strategic alliances between health professionals, organizations of people living with HIV/AIDS, and affected communities. Legal and human rights advocacy strategies are increasingly productive and necessary. PMID:12571725

The emergence of HIV-1 group M subtype B in North American men who have sex with men was a key turning point in the HIV/AIDS pandemic. Phylogenetic studies have suggested cryptic subtype B circulation in the United States (US) throughout the 1970s and an even older presence in the Caribbean. However, these temporal and geographical inferences, based upon partial HIV-1 genomes that postdate the recognition of AIDS in 1981, remain contentious and the earliest movements of the virus within the US are unknown. We serologically screened >2,000 1970s serum samples and developed a highly sensitive approach for recovering viral RNA from degraded archival samples. Here, we report eight coding-complete genomes from US serum samples from 1978-1979-eight of the nine oldest HIV-1 group M genomes to date. This early, full-genome 'snapshot' reveals that the US HIV-1 epidemic exhibited extensive genetic diversity in the 1970s but also provides strong evidence for its emergence from a pre-existing Caribbean epidemic. Bayesian phylogenetic analyses estimate the jump to the US at around 1970 and place the ancestral US virus in New York City with 0.99 posterior probability support, strongly suggesting this was the crucial hub of early US HIV/AIDS diversification. Logistic growth coalescent models reveal epidemic doubling times of 0.86 and 1.12 years for the US and Caribbean, respectively, suggesting rapid early expansion in each location. Comparisons with more recent data reveal many of these insights to be unattainable without archival, full-genome sequences. We also recovered the HIV-1 genome from the individual known as 'Patient 0' (ref. 5) and found neither biological nor historical evidence that he was the primary case in the US or for subtype B as a whole. We discuss the genesis and persistence of this belief in the light of these evolutionary insights.

Background HIV/AIDS and Ebola Virus Disease (EVD) are contemporary epidemics associated with significant social stigma in which communities affected suffer from social rejection, violence, and diminished quality of life. Objective To compare and contrast stigma related to HIV/AIDS and EVD, and strategically think how lessons learned from HIV stigma can be applied to the current EVD epidemic. Methods To identify relevant articles about HIV/AIDS and EVD-related stigma, we conducted an extensive literature review using multiple search engines. PubMed was used to search for relevant peer-reviewed journal articles and Google for online sources. We also consulted the websites of the World Health Organization (WHO), Centers for Disease Control and Prevention (CDC), and the National Institutes of Health to retrieve up-to-date information about EVD and HIV/AIDS. Results Many stigmatizing attitudes and behaviors directed towards those with EVD are strikingly similar to those with HIV/AIDS but there are significant differences worthy of discussion. Both diseases are life-threatening and there is no medical cure. Additionally misinformation about affected groups and modes of transmission runs rampant. Unlike in persons with EVD, historically criminalized and marginalized populations carry a disproportionately higher risk for HIV infection. Moreover, mortality due to EVD occurs within a shorter time span as compared to HIV/AIDS. Conclusions Stigma disrupts quality of life, whether it is associated with HIV infection or EVD. When addressing EVD, we must think beyond the immediate clinical therapeutic response, to possible HIV implications of serum treatment. There are emerging social concerns of stigma associated with EVD infection and double stigma associated with EVD and HIV infection. Drawing upon lessons learned from HIV, we must work to empower and mobilize prominent members of the community, those who recovered from the disease, and organizations working at the grassroots

There is a potentially high risk of HIV spreading from people living with HIV/AIDS. We conducted a cross-sectional study to examine HIV risk behaviours and their determinants among people living with HIV/AIDS. Eighty-two percent had been sexually active. Sex with multiple partners was reported by 20% and consistent condom use by about one third. More than half of the participants (52%) reported having injected drugs during the previous month, and 35% of those had shared needles and syringes. Voluntary HIV testing and having received condoms or injection equipment from the local HIV prevention program, were found to be significantly associated with fewer HIV risk behaviours. Having learned recently about personal HIV status, multiple sex partners, low educational attainment and young age were found to be associated with higher HIV risk behaviours. Giving high priority to targeted preventive and support programmes is likely to be a highly cost-effective strategy.

A higher prevalence of QT prolongation has been reported among HIV/AIDS patients, possibly related to drugs prescribed for them or to an acquired form of long QT syndrome. A prolonged QTc is a predictor of cardiovascular mortality. We set out to study this interval in a group of AIDS patients. One-hundred consecutive AIDS patients admitted into the Jos University Teaching Hospital and who satisfied the inclusion criteria were recruited. All were evaluated for symptomatology of cardiovascular disease and had a 12-lead surface electrocardiogram recording. QT interval, taken from the onset of the QRS complex to the end of the T wave, was corrected for heart rate. Eighty HIV-negative, healthy persons and 78 HIV-positive, asymptomatic subjects were used as controls. Forty-five percent of the AIDS patients had prolonged QTc interval. Prolonged QTc was present in 28% of HIV-positive controls and 10% of HIV-negative controls. The mean QTc interval differs significantly between the AIDS patients and the two control groups. From our study, Nigerian HIV-positive asymptomatic subjects have higher prevalence of QTc prolongation compared to HIV-negative subjects and, as they move to AIDS, the prevalence of QTc prolongation increases. This makes for increased cardiovascular mortality. PMID:16396057

Human Immunodeficiency Virus (HIV) is the etiologic agent of Acquired Immunodeficiency Syndrome (AIDS). HIV/AIDS is a disease that, compared with the not so distant past, is now better held in check by current antiretroviral drugs. However, it remains a disease not solved. Highly active antiretroviral therapy (HAART) generally uses two non-nucleoside and one nucleoside reverse transcriptase (RT) inhibitor or two non-nucleoside RT and one protease inhibitor. HAART is far more effective than the mono- or duo-therapy of the past, which used compounds like the nucleoside reverse transcriptase inhibitor AZT or two nucleoside reverse transcriptase inhibitors. However, even with the relatively potent drug cocktails that comprise HAART, there are the issues of (i). HIV escape mutants, (ii). an apparent need to take the drugs in an ongoing manner, and (iii). the drugs' side effects that are often severe. This review speaks to the potential addition to these potent regimens of another regimen, namely the genetic modification of target hematopoietic cells. Such a new treatment paradigm is conceptually attractive as it may yield the constant intracellular expression of an anti-HIV gene that acts to inhibit HIV replication and pathogenicity. A body of preclinical work exists showing the inhibition of HIV replication and decreased HIV pathogenicity by anti-HIV genetic agents. This preclinical work used hematopoietic cell lines and primary cells as the target tissue. More recently, several clinical trials have sought to test this concept in vivo.

As long as there is no cure for AIDS, the only effective means of containing its spread is prevention, primarily through public education. Cuba's AIDS Prevention Group is a community-based organization whose main purpose is to support the National HIV/AIDS Program's prevention and education efforts. The Group's Memorias Project uses the creation and display of memorial quilts to put a human face on AIDS statistics and stimulate public reflection on issues related to the disease and society.

Neuropsychological and immunological parameters were studied in 36 AIDS patients with early disease and without clinical, laboratory, and neuroradiological signs of CNS impairment, and also in 33 asymptomatic HIV seropositive subjects. Many AIDS patients performed abnormally on timed psychomotor tasks, tasks involving sequencing and "set-shifting", and memory tasks stressing attention, learning, active retrieval, and monitoring of information. Asymptomatic HIV seropositive subjects as a group did not perform significantly worse than controls. However, on the basis of a cut off number of pathological performances on neuropsychological tasks, 52.8% of AIDS and 30.3% of asymptomatic HIV seropositive subjects had cognitive impairment, compared with 3.9% of HIV seronegative controls. Low values of CD4+ cells and of CD4+/CD8+ ratio and high titres of P-24 antigen in the blood prevailed among subjects with cognitive impairment, especially in the asymptomatic HIV seropositive group.

HIV/AIDS is an important public health problem globally. An affordable, easy-to-deliver and protective HIV vaccine is therefore required to curb the pandemic from spreading further. Recombinant Salmonella bacteria can be harnessed to vector HIV antigens or DNA vaccines to the immune system for induction of specific protective immunity. These are capable of activating the innate, humoral and cellular immune responses at both mucosal and systemic compartments. Several studies have already demonstrated the utility of live recombinant Salmonella in delivering expressed foreign antigens as well as DNA vaccines to the host immune system. This review gives an overview of the studies in which recombinant Salmonella bacteria were used to vector HIV/AIDS antigens and DNA vaccines. Most of the recombinant Salmonella-based HIV/AIDS vaccines developed so far have only been tested in animals (mainly mice) and are yet to reach human trials.

The human immunodeficiency virus type 1 (HIV-1) Nef protein has several independent functions that might contribute to efficient viral replication in vivo. Since HIV-1 adapts rapidly to its host environment, we investigated if different Nef properties are associated with disease progression. Functional analysis revealed that nef alleles obtained during late stages of infection did not efficiently downmodulate class I major histocompatibility complex but were highly active in the stimulation of viral replication. In comparison, functional activity in downregulation of CD4 and enhancement of HIV-1 infectivity were maintained or enhanced after AIDS progression. Our results demonstrate that various Nef activities are modulated during the course of HIV-1 infection to maintain high viral loads at different stages of disease progression. These findings suggest that all in vitro Nef functions investigated contribute to AIDS pathogenesis and indicate that nef variants with increased pathogenicity emerge in a significant number of HIV-1-infected individuals.

The psychosocial impact of human immunodeficiency virus (HIV) disease has been recognized since the beginning of the epidemic for affected adults, but there has been less focus on the impact of HIV on young people. Among HIV-positive (HIV+) adults, high levels of distress, psychiatric symptoms, and their associations with worse health outcomes were recognized early in the epidemic. Subsequently, many studies have focused on understanding the prevalence of psychiatric symptoms among HIV+ adults and on identifying effective treatments for these symptoms. Fewer studies have examined these symptoms and their treatments among HIV+ children and adolescents. This article reviews what is known about psychiatric syndromes among HIV+ youths, their treatments, and other psychosocial factors of concern to the psychiatrist when treating children and adolescents with HIV disease.

The latest generation of lentiviral vectors based on HIV-1 is one of the most efficient tools for gene transduction of mammalian cells. However, the possible employment of HIV-based vectors in clinical trials is a very controversial issue, mainly due to safety and ethical concerns. HIV-1 is a lethal pathogenic agent, which induces AIDS. Genetic vectors must derive either from viruses that are not pathogenic in humans, or that eventually just cause mild illnesses. Patients exposed to HIV-based vectors will test seropositive to certain components of HIV-1. In addition, there might be other possible adverse effects in patients that cannot be predicted, as many aspects of the pathogenesis of AIDS have not been completely understood yet. On these grounds, it seems necessary to improve the design of other lentiviral vectors, which derive from viruses that are not pathogenic in humans and are distantly related to primate retroviridae.

The role of direct virus infection as a determining factor in acquired immunodeficiency syndrome (AIDS) dementia was investigated using in situ hybridisation for human immunodeficiency virus (HIV) and human cytomegalovirus (HCMV). Four of the five AIDS dementia patients in this series demonstrated HIV infected cells distributed in widely different parts of the brain, but only one case showed HCMV infected cells. The greater abundance of HIV was in subcortical white matter in nodular areas consisting of monocyte/macrophage infiltrates. The cells were occasionally arranged as a multinucleated syncitium. In two cases, a few large cells with the appearance of neurons were positive for HIV hybridisation. By appropriate treatment with ribonuclease, it was shown that hybridisation was primarily to HIV RNA. HCMV infected cells were observed in small numbers in only one of the positive cases, suggesting that HCMV is not a determining factor in AIDS dementia. HCMV positive cells were located in the grey matter, with an appearance suggestive of neurons. Cells expressing the MHC-class II antigen HLA-DR, a marker of reactive microglia and macrophages, were observed to be extensive in affected brain sections in the one case examined. These cells were present in greater number than HIV infected cells. In this case, extensive numbers of HIV infected cells were noticed along the peripheral margin of the substantia innominata. This could indicate infection in this case of a critical brain region from the cerebrospinal fluid. Images PMID:2543795

The condition of a chimpanzee (C499) infected with three different isolates of human immunodeficiency virus type 1 (HIV-1) for over 10 years progressed to AIDS. Disease development in this animal was characterized by (i) a decline in CD4+ cells over the last 3 years; (ii) an increase in viral loads in plasma; (iii) the presence of a virus, termed HIV-1JC, which is cytopathic for chimpanzee peripheral blood mononuclear cells; and (iv) the presence of an opportunistic infection and blood dyscrasias. Genetic analysis of the V1-V2 region of the envelope gene of HIV-1JC showed that the virus present in C499 was significantly divergent from all inoculating viruses (> or = 16% divergent at the amino acid level) and was suggestive of a large quasispecies. Blood from C499 transfused into an uninfected chimpanzee (C455) induced a rapid and sustained CD4+-cell decline in the latter animal, concomitant with high plasma viral loads. These results show that HIV-1 can induce AIDS in chimpanzees and suggest that long-term passage of HIV-1 in chimpanzees can result in the development of a more pathogenic virus. PMID:9094687

Current therapy for controlling HIV-1 infection and preventing AIDS progression has profoundly decreased viral replication in cells susceptible to HIV-1 infection, but it does not eliminate the low level of viral replication in latently infected cells which contain integrated copies of HIV-1 proviral DNA. There is an urgent need for the development of HIV-1 genome eradication strategies that will lead to a permanent or “sterile” cure of HIV-1/AIDS. In the past few years, novel nuclease-initiated genome editing tools have been developing rapidly, including ZFNs, TALENs, and the CRISPR/Cas9 system. These surgical knives, which can excise any genome, provide a great opportunity to eradicate the HIV-1 genome by targeting highly conserved regions of the HIV-1 long terminal repeats or essential viral genes. Given the time consuming and costly engineering of target-specific ZFNs and TALENs, the RNA-guided endonuclease Cas9 technology has emerged as a simpler and more versatile technology to allow permanent removal of integrated HIV-1 proviral DNA in eukaryotic cells, and hopefully animal models or human patients. The major unmet challenges of this approach at present include inefficient nuclease gene delivery, potential off-target cleavage, and cell-specific genome targeting. Nanoparticle or lentivirus-mediated delivery of next generation Cas9 technologies including nickase or RNA-guided FokI nuclease (RFN) will further improve the potential for genome editing to become a promising approach for curing HIV-1/AIDS.

OBJECTIVE. This study reports the results of a behavior change intervention offered to women at high risk for human immunodeficiency virus (HIV) infection seen in an urban primary health care clinic. METHODS. Participants were 197 women randomly assigned to either an HIV/acquired immunodeficiency syndrome (AIDS) risk reduction group or a comparison group. Women in the HIV/AIDS intervention group attended five group sessions focusing on risk education; skills training in condom use, sexual assertiveness, problem solving, and risk trigger self-management; and peer support for change efforts. Women in the comparison group attended sessions on health topics unrelated to AIDS. RESULTS. At the 3-month follow-up, women in the HIV/AIDS intervention group had increased in sexual communication and negotiation skills. Unprotected sexual intercourse had declined significantly and condom use had increased from 26% to 56% of all intercourse occasions. Women in the comparison group showed no change. CONCLUSIONS. Socially disadvantaged women can be assisted in reducing their risk of contracting HIV infection. Risk reduction behavior change interventions should be offered routinely in primary health care clinics serving low-income and high-risk patients. PMID:7998630

We conducted a hospital-based survey on prevalence and risk factors of HIV-1/2 and other viral infections in Zanzibar archipelago. Blood samples, socio-demographic and behavioural data were collected from 2697 patients. The overall HIV prevalence was 2.9%. About 1.4%, 2.1%, 4.2% of antenatal clinic (ANC) attendees and 2.1%, 3.7%, 5.3% of blood donors were, respectively, HIV-Abs-, HTLV-Abs- and HBs-Ag-positive; 5.5% of blood donors were HCV-affected. Co-infections were rare. Exactly 3.4% of the children aged 6-10 years were HIV-positive. People aged 26-35 years [adjusted odds ratio (AOR) 4.4, 95% CI (confidence interval) 1.72-11.22; P = 0.002], illiterate subjects (AOR 3.6, 95% CI 1.65-7.98; P = 0.001) mobile workers (AOR 7.0, 95% CI 1.41-34.62; P = 0.02) and previously operated patients (AOR 1.9, 95% CI 1.02-3.66; P = 0.04) were at higher risk for HIV/AIDS. Any of the examined factors were associated with hepatitis B virus, hepatitis C virus and human T lymphotropic virus type 1/2 transmission. HIV/AIDS prevention strategies must primarily be addressed to traditional high-risk groups and secondarily to unsafe health care procedures in relatively preserved sub-Saharan areas.

Studies have shown that chronic illness patients encounter difficulties in the social sharing of emotions. Do HIV/AIDS patients present distinguishing traits in the inhibition of illness and non-illness-related emotions? The differences in the social sharing of emotion between 35 HIV/AIDS, 35 diabetic and 34 cancer outpatients were studied. A questionnaire assessed illness-related emotions, social sharing of emotion and emotional inhibition. The HIV/AIDS group significantly presented superior scoring in shame, guilt and non-sharing of illness-related emotions, lower frequencies of social sharing of emotion and less sharing partners. These findings could lead to future research examining the emotional expression of guilt and shame in HIV/AIDS.
INTRODUCTION: The prevalence of human immunodeficiency virus (HIV) among adults and mortality rates among under-5-year-olds have increased or stagnated in many countries. The objective of this study was to investigate whether there is a link between under-5 mortality trends and the prevalence of HIV among adults and, if so, to assess the magnitude of the effect of adult HIV prevalence on under-5 mortality rates. METHOD: Data from Demographic and Health Surveys were used to establish the trends in under-5 mortality rates for 25 countries for which there are data for at least two points in time. Countries were ranked according to the most recent adult HIV prevalence data and grouped in three categories: those with very high HIV prevalence (> or = 5%); those with moderately high prevalence (1-4.9%); and those with low prevalence (< 1%). A mathematical model was fitted to obtain an estimate of the contribution of HIV/AIDS to the level of under-5 mortality in each country. RESULTS: Under-5 mortality rates showed an increase in most countries with high adult HIV prevalence, but a decrease in almost every country with moderately high or low prevalence. The estimated contribution of adult HIV prevalence to the observed level of under-5 mortality was highest (up to 61%) in Zimbabwe (where HIV prevalence was highest) and tended to decrease with the level of HIV prevalence. DISCUSSION: The contribution of HIV/AIDS to childhood mortality therefore appears to be most noticeable in settings where the epidemic is most severe. PMID:11100615

Though still limited in scale, work with men to achieve gender equality is occurring on every continent and in many countries. A rapidly expanding evidence base demonstrates that rigorously implemented initiatives targeting men can change social practices that affect the health of both sexes, particularly in the context of HIV and AIDS. Too often however, messages only address the harm that regressive masculinity norms cause women, while neglecting the damage done to men by these norms. This article calls for a more inclusive approach which recognizes that men, far from being a monolithic group, have unequal access to health and rights depending on other intersecting forms of discrimination based on race, class, sexuality, disability, nationality, and the like. Messages that target men only as holders of privilege miss men who are disempowered or who themselves challenge rigid gender roles. The article makes recommendations which move beyond treating men simply as "the problem", and instead lays a foundation for engaging men both as agents of change and holders of rights to the ultimate benefit of women and men. Human rights and other policy interventions must avoid regressive stereotyping, and successful local initiatives should be taken to scale nationally and internationally.

This study is designed to assess AIDS knowledge among Homeopathy educators and physicians in India, which has not been evaluated previously. India now has the largest number of HIV infected persons worldwide, with an estimated cumulative 5.1 million infections. Homeopathy is the dominant system among the nationally-recognized alternative or complementary systems of medicine, which collectively provide health care to around 600 million people in India. Homeopathy, with its holistic and patient-centered approach, has a wide reach to people at risk of contracting human immunodeficiency virus (HIV). Participants were 68 homeopathy physicians (34 educators and 34 practitioners) who completed a CDC questionnaire measuring HIV/AIDS Knowledge regarding AIDS. This study reports the current level of knowledge of, and attitudes about, HIV/AIDS among homeopathy educators and practitioners. These findings will assist in the development of an education module to equip homeopathic health care personnel to impart accurate AIDS information and prevention counseling to their patients in an efficient manner.

African American women bear a disproportionate burden of HIV/AIDS in the United States. Although they constitute only 13% of the US population, African Americans account for nearly 65% of all new HIV infections among American women. In addition, this population suffers comparatively greater adverse health outcomes related to HIV status. African American women living with HIV in the South may be further burdened by HIV/AIDS stigma, which is comparatively more pronounced in this region. To further explore this burden, we used narrative data and the Social Ecological Model to explore how African American women living with HIV in the US South recount, conceptualize, and cope with HIV/AIDS stigma at interpersonal, community, and institutional levels. Our narrative analysis suggests that HIV-positive African American women living in the South are vulnerable to experiences of multilevel HIV stigma in various settings and contexts across multiple domains of life. Stigma subsequently complicated disclosure decisions and made it difficult for women to feel supported in particular social, professional and medical settings that are generally regarded as safe spaces for noninfected individuals. Findings suggest that the debilitating and compounded effect of multilevel HIV/AIDS stigma on HIV-positive African American women in the South warrants closer examination to tailor approaches that effectively address the unique needs of this population.

Overwhelming impact has been established among different aspects and burden of incurable HIV and AIDS is increasing day-by-day globally. The aim of this article is to discuss the potential benefits and strengths of an education system in the absence of remedy and help to develop future strategies. Education has great impact on HIV and AIDS and vice-versa. An education plays a vital role to curb the transmission of HIV and AIDS thorough capacity building, provides information, reduces vulnerability, empowerment, improve life skill, maintain equity, reduce dependence, stigma, and discrimination, where are abundance foundations for HIV infection. HIV and AIDS has role for devastation of education system and level which has great impact on productivity, economic growth, demand, supply and daily life of human being. Low and middle income countries needs to be improve recording and reporting systems related to impact of HIV and AIDS on education. By analyzing preceding evidences, policy makers or governance feels to reformulate policies relating to education and health. Evidence based policy and program will be more useful to address distressing squall of epidemic.

This study utilizes a quasi-experimental pre- and post-test survey design to examine the effects of a course, called HIV/AIDS: Science, Behavior, and Society, on undergraduate students’ HIV knowledge, attitudes and risky sexual behaviors. With the assistance of social work faculty the course incorporates experiential learning pedagogy and a transdisciplinary perspective. Although the course was not designed as a prevention program, the theory of health behavior suggests the incorporation of experiential learning will impact crucial HIV/AIDS attitudes and behaviors. When regression models were applied, relative to the comparison group (N = 111), the HIV/AIDS class students (N = 79) reported an increase in post-test HIV knowledge, perceived susceptibility to HIV among females, and a reduction of risky sexual attitudes among sexually active students.

The continuing paucity of effective interventions to reduce HIV/AIDS stigma is troubling, given that stigma has long been recognized as a significant barrier to HIV prevention, treatment, care, and support. Ineffectual HIV/AIDS stigma-reduction interventions are the product of inadequate conceptual frameworks and methodological tools. And while there is a paucity of effective interventions to reduce stigma, there is no shortage of conceptual frameworks intending to offer a comprehensive understanding of stigma, ranging from sociocognitive models at the individual level to structural models at the macrolevel. Observations highlighting inadequacies in the individualistic and structural models are offered, followed by the theory of structuration as a possible complementary conceptual base for designing HIV/AIDS stigma-reduction interventions.

A scoping review was conducted to describe the epidemiological characteristics of the human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic in the State of Amazonas, Brazil, from 2001 to 2012, and temporary patterns were estimated from surveillance data. The results suggest that in its third decade, the Amazon HIV/AIDS epidemic is far from being stabilized and displays rising AIDS incidence and mortality rates and late diagnoses. The data suggest that AIDS cases are hitting mostly young adults and have recently shifted toward men, both homosexual and heterosexual. AIDS cases among the indigenous people have remained stable and low. However, the epidemic has disseminated to the interior of the state, which adds difficulties to its control, given the geographical isolation, logistical barriers, and culturally and ethnically diverse population. Antiretroviral (ARV) therapy has been decentralized, but peripheral ARV services are still insufficient and too distant from people who need them. Recently, the expansion of point-of-care (POC) rapid HIV testing has been contributing to overcoming logistical barriers. Other new POC devices, such as the PIMA CD4 analyzer, will bring the laboratory to the patient. AIDS uniquely coexists with other tropical infections, sharing their epidemiological profiles. The increased demand for HIV/AIDS care services can only be satisfied through increased decentralization to peripheral health units, which can also naturally integrate care with other tropical infections and can promote a shift from vertical to integrated programming. Future challenges involve building surveillance data on HIV case notification and covering the spectrum of engagement in care, including adherence to treatment and follow-up loss.
Globally, acquired immunodeficiency syndrome (AIDS) is an epidemic, severe and fatal disease. Along with the etiological factors of human immunodeficiency virus infection (HIV+) and decreased immunity, there are a number of other risk factors including opportunistic infection, malnutrition, wasting syndrome, and oxidative stress. The nutritional problems have been shown to be significant and contribute to health and death in HIV+/AIDS patients. Weight loss, lean tissue depletion, lipoatrophy, loss of appetite, diarrhea, and the hypermetabolic state each increase risk of death. The role of nutrition and how oxidative stress is involved in the pathogenesis of HIV+ leading to AIDS is reviewed. Studies consistently show that serum antioxidant vitamins and minerals decrease while oxidative stress increases during AIDS progression. The optimization of nutritional status, intervention with foods and supplements, including nutrients and other bio-active food components, are needed to maintain the immune system. Various food components may be recommended to reduce the incidence and severity of infectious illnesses by forms of bio-protection which include reduced oxidative stress due to reactive oxygen species which stimulate HIV replication and AIDS progression. Probiotics or lactic acid bacteria and prebiotics are sometimes given on the presumed basis that they help maintain integrity of mucosal surfaces, improve antibody responses and increase white blood cell production. People with HIV+/AIDS can be informed about the basic concepts of optimal nutrition by identifying key foods and nutrients, along with lifestyle changes, that contribute to a strengthened immune system. Moreover, nutritional management, counseling and education should be beneficial to the quality and extension of life in AIDS.

Background: HIV/AIDS control are one of the most important goals of the health systems. The aim of this study was to determine how HIV/AIDS control was initiated among policy makers’ agenda setting in Iran. Methods: A qualitative research (semi-structured interview) was conducted using Kingdon’s framework (problem, policy and politics streams, and policy windows and policy entrepreneurs) to analysis HIV/AIDS agenda setting in Iran. Thirty-two policy makers, managers, specialists, and researchers were interviewed. Also, 30 policy documents were analyzed. Framework analysis method was used for data analysis. Results: the increase of HIV among Injecting drug users (IDUs) and Female Sex Workers (FSWs), lack of control of their high-risk behaviors, and exceeding the HIV into concentrated phase were examples of problem stream. Policy stream was evidence-based solutions that highlighted the need for changing strategies for dealing with such a problem and finding technically feasible and acceptable solutions. Iran’s participation in United Nations General Assembly special sessions on HIV/AIDS (UNGASS), the establishment of National AIDS Committee; highlighting AIDS control in Iran’s five years development program and the support of the judiciary system of harm reduction policies were examples of politics stream. Policy entrepreneurs linking these streams put the HIV/AIDS on the national agenda (policy windows) and provide their solutions. Conclusion: There were mutual interactions among these three streams and sometimes, they weakened or reinforced each other. Future studies are recommended to understand the interactions between these streams’ parts and perhaps develop further Kingdon’s framework, especially in the health sector. PMID:27579283

To investigate the association of antigen specific CD4 T cell activation with HIV disease progression and AIDS-related central nervous system damage, T cell proliferation responses to HIV, CMV, and HSV were evaluated in infected individuals. CD4 T cell loss and neurocognitive impairment were assessed at 6-mo intervals. Individuals with known times of seroconversion who responded to more HIV peptides were at greater risk of progressing to < 200 CD4 T cells (P = 0.04) and dying (P = 0.03) than those with responses to fewer peptides. A positive correlation (0.52) was seen between the breadth of the HIV proliferation response and HIV plasma RNA levels. Higher proliferation responses to CMV and HSV were also associated with more rapid CD4 loss (P = 0.05). HLA phenotyped individuals (n = 150) with two HLA-DR alleles associated with response to more HIV peptides and CMV (DR-2,5,w6,10) were less likely to develop neurocognitive (P = 0.002) and neurologic impairment (P = 0.04), but were not protected from CD4 loss and death. Thus, the ability to generate a greater T cell proliferation response to HIV and opportunistic herpes viruses may lead to resistance to central nervous system damage, but also risk of more rapid HIV disease progression.

Systemic non-Hodgkin lymphoma (S-NHL) is a common malignancy during HIV infection, and it is hypothesized that infectious agents may be involved in the etiology. Epstein-Barr virus DNA is found in <40% of patients with AIDS-related S-NHL, suggesting that other oncogenic viruses, such as polyomaviruses, may play a role in pathogenesis. We analyzed AIDS-related S-NHL samples, NHL samples from HIV-negative patients, peripheral blood leukocytes from HIV-infected and -uninfected patients without NHL, and lymph nodes without tumors from HIV-infected patients. Specimens were examined by polymerase chain reaction analysis with use of primers specific for an N-terminal region of the oncoprotein large tumor antigen ( T-ag ) gene conserved among all three polyomaviruses (simian virus 40 [SV40], JC virus, and BK virus). Polyomavirus T-ag DNA sequences, proven to be SV40-specific, were detected more frequently in AIDS-related S-NHL samples (6 of 26) than in peripheral blood leukocytes from HIV-infected patients (6 of 26 vs. 0 of 69; p =.0001), NHL samples from HIV-negative patients (6 of 26 vs. 0 of 10; p =.09), or lymph nodes (6 of 26 vs. 0 of 7; p =.16). Sequences of C-terminal T-ag DNA from SV40 were amplified from two AIDS-related S-NHL samples. Epstein-Barr virus DNA sequences were detected in 38% (10 of 26) AIDS-related S-NHL samples, 50% (5 of 10) HIV-negative S-NHL samples, and 57% (4 of 7) lymph nodes. None of the S-NHL samples were positive for both Epstein-Barr virus DNA and SV40 DNA. Further studies of the possible role of SV40 in the pathogenesis of S-NHL are warranted.

Although human immunodeficiency virus (HIV) types 1 and 2 are closely related lentiviruses with similar replication cycles, HIV-2 infection is associated with slower progression to AIDS, a higher proportion of long term non-progressors, and lower rates of transmission than HIV-1, likely as a consequence of a lower viral load during HIV-2 infection. A mechanistic explanation for the differential viral load remains unclear but knowledge of differences in particle production between HIV-1 and HIV-2 may help to shed light on this issue. In contrast to HIV-1, little is known about the assembly of HIV-2 particles, and the trafficking of HIV-2 Gag, the structural component of the virus, within cells. We have established that HIV-2 Gag accumulates in intracellular CD63 positive compartments, from which it may be delivered or recycled to the cell surface, or degraded. HIV-2 particle release was dependent on the adaptor protein complex AP-3 and the newly identified AP-5 complex, but much less so on AP-1. In contrast, HIV-1 particle release required AP-1 and AP-3, but not AP-5. AP-2, an essential component of clathrin-mediated endocytosis, which was previously shown to be inhibitory to HIV-1 particle release, had no effect on HIV-2. The differential requirement for adaptor protein complexes confirmed that HIV-1 and HIV-2 Gag have distinct cellular trafficking pathways, and that HIV-2 particles may be more susceptible to degradation prior to release.

Due to advances in treatment, persons living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) are living longer, but with aging, immune deficits, and lifestyle factors, they are at increased risk for cancer. This challenges community-based AIDS service organizations (ASOs) to address the growing cancer needs of persons living with HIV/AIDS (PLWHA). Community-based participatory research was applied to engage ASOs in exploring their capacities and needs for integrating cancer-focused programming into their services. Focus groups were conducted with a community advisory board (CAB) representing 10 community-based organizations serving PLWHA. Three 90-minute, serial focus groups were conducted with a mean number of seven participants. Topics explored CAB members’ organizational capacities and needs in cancer prevention, detection, treatment, and survivorship. Transcript analyses identified six themes: (a) agencies have limited experience with cancer-focused programs, which were not framed as cancer specific; (b) agencies need resources and collaborative partnerships to effectively incorporate cancer services; (c) staff and clients must be educated about the relevance of cancer to HIV/AIDS; (d) agencies want to know about linkages between HIV/AIDS and cancer; (e) cancer care providers should be culturally competent; and (f) agencies see opportunities to improve their services through research participation but are wary. Agency capacities were strong in relationships with clients and cultural competency, a holistic view of PLWHA health, expertise in prevention activities, and eagerness to be on the cutting edge of knowledge. Cancer education and prevention were of greatest interest and considered most feasible, suggesting that future projects develop accordingly. These findings suggest a high level of receptivity to expanding or initiating cancer-focused activities but with a clear need for education and awareness building

Malawi, a very poor country located in southern Africa, is no exception to the growing trend and severity in HIV prevalence. By the end of 2003 there were 900 000 adults and children in Malawi living with HIV/AIDS. Adult prevalence was estimated to be 15%, which is higher than the 7.1% average rate for sub-Saharan Africa. In order to understand the spread of HIV/AIDS it is imperative to address the economic, social, cultural, and political issues that impact on women's contraction and spread of the virus. We do so in this paper by critically examining the gendered context of HIV/AIDS with reference to Malawi. The theoretical framework for this research focuses on poverty, gender relations, regional migration patterns, and global economic changes which place women in highly vulnerable situations. The study was conducted in a low-income area in Lilongwe, the capital city of Malawi. In 2003 and 2004, 60 randomly selected women who lived in a low socioeconomic residential area completed a structured interview on issues concerning individual economic situations, marriage history, fertility, family planning and social networks, gender, sexual partnerships, and HIV/AIDS. Focus group interviews were also conducted with an additional 20 women. The results of our study indicate that the rising epidemic among women in Malawi is firstly driven by poverty which limits their options. Secondly, gender inequality and asymmetrical sexual relations are basic to spreading HIV/AIDS among women. Thirdly, in spite of their awareness through media and health care professionals, women are unable to protect themselves, which further increases their vulnerability.

Housing for people living with HIV/AIDS has been linked to a number of positive physical and mental health outcomes, in addition to decreased sexual and drug-related risk behavior. The current study identified service priorities for people living with HIV/AIDS, services provided by HIV/AIDS housing agencies, and unmet service needs for people living with HIV/AIDS through a nationwide telephone survey of HIV/AIDS housing agencies in the United States. Housing, alcohol/drug treatment, and mental health services were identified as the three highest priorities for people living with HIV/AIDS and assistance finding employment, dental care, vocational assistance, and mental health services were the top needs not being met. Differences by geographical region were also examined. Findings indicate that while housing affords people living with HIV/AIDS access to services, there are still areas (e.g., mental health services) where gaps in linkages to care exist. PMID:23305552

A consulting firm conducted interviews with managers of 16 businesses in 3 Kenyan cities, representatives of 2 trade unions, focus groups with workers at 13 companies, and an analysis of financial/labor data from 4 companies. It then did a needs assessment. The business types were light industry, manufacturing companies, tourism organizations, transport firms, agro-industrial and plantation businesses, and the service industry. Only one company followed all the workplace policy principles recommended by the World Health Organization and the International Labor Organization. Six businesses required all applicants and/or employees to undergo HIV testing. All their managers claimed that they would not discriminate against HIV-infected workers. Many workers thought that they would be fired if they were--or were suspected to be--HIV positive. Lack of a non-discrimination policy brings about worker mistrust of management. 11 companies had some type of HIV/AIDS education program. All the programs generated positive feedback. The main reasons for not providing HIV/AIDS education for the remaining 5 companies were: no employee requests, fears that it would be taboo, and assumptions that workers could receive adequate information elsewhere. More than 90% of all companies distributed condoms. 60% offered sexually transmitted disease diagnosis and treatment. About 33% offered counseling. Four companies provided volunteer HIV testing. Almost 50% of companies received financial or other external support for their programs. Most managers thought AIDS to be a problem mainly with manual staff and not with professional staff. Almost all businesses offered some medical benefits. The future impact of HIV/AIDS would be $90/employee/year (by 2005, $260) due to health care costs, absenteeism, retraining, and burial benefits. The annual costs of a comprehensive workplace HIV/AIDS prevention program varied from $18 to $54/worker at one company.
HIV-1 can persist in a latent form in resting memory CD4+ cells and macrophages carrying an integrated copy of the HIV genome. Because of the presence of these stable reservoir cells, eradication by antiretroviral therapy is unlikely and in order to achieve eradication, alternative treatment options are required. Stem cell transplantation has been considered previously to effect the clinical course of HIV-infection but in practice eradication or virus control was not achievable. However, modifications of stem cell transplantation using natural or artificial resistant cell sources, combination with new techniques of gene editing or generating cytotoxic anti HIV effector cells have stimulated this field of HIV cell therapy substantially. Here, we look back on 30 years of stem cell therapy in HIV patients and discuss most recent developments in this direction.

Reviews of the literature indicate that nurses feel ill-informed about HIV/AIDS and that poor knowledge is associated with anxiety and negative attitudes towards infected patients and their care. Although some studies have sought to identify the sources of HIV/AIDS information available to nurses, few have attempted to understand how nurses evaluate such sources. In this study in 1992, 15 sources of HIV/AIDS information were identified during group discussions with nursing staff and nurse tutors. 277 nursing staff evaluated each of the sources in terms of perceived frequency (how often the source is used) and six items chosen to assess the usability and usefulness of each source (e.g. how informative the source is, how easy it is to understand). The results indicate that in-service training, basic training and professional colleagues are the sources evaluated most highly while posters and advertisements, television and radio and popular newspapers are the most frequently used sources of information. Trades unions' journals and pamphlets are the least frequently used sources of information and receive only modest evaluations. 20% of respondents report never having received any training regarding HIV and AIDS. Implications for the future provision of HIV/AIDS information and directions for further research are discussed.

ABSTRACT Objective: to analyze the offering of health actions and services for the control of tuberculosis for people living with HIV/AIDS being followed up in the Specialized Care Services for HIV/AIDS in Ribeirão Preto, SP, Brazil. Method: quantitative, exploratory survey study. Participated 253 people living with HIV/AIDS followed up by this service, considering as inclusion criteria: individuals older than 18 years living in the city and not inmates. Data collection was conducted from January 2012 to May 2013 through interviews with the support of a specific instrument. Data were analyzed using indicators and a composite index. Results: the offering of services for the control of tuberculosis in people living with HIV/AIDS by municipal services was considered as intermediate, reinforcing the need for better planning for comprehensive assistance, coordination of professionals in teams and among the services network, in addition to professional training and continuing education. Conclusion: it is necessary to implement strategies that promote shared actions between TB and HIV / AIDS programs and between different services in order to strengthen the local care network, aimed at producing an individualized care, comprehensive and responsive.

Although oral combination antiretroviral therapy effectively clears plasma HIV, patients on oral drugs exhibit much lower drug concentrations in lymph nodes than blood. This drug insufficiency is linked to residual HIV in cells of lymph nodes. While nanoformulations improve drug solubility, safety and delivery, most HIV nanoformulations are intended to extend plasma levels. A stable nanodrug combination that transports, delivers and accumulates in lymph nodes is needed to clear HIV in lymphoid tissues. This review discusses limitations of current oral combination antiretroviral therapy and advances in anti-HIV nanoformulations. A ‘systems approach’ has been proposed to overcome these limitations. This concept has been used to develop nanoformulations for overcoming drug insufficiency, extending cell and tissue exposure and clearing virus for treating HIV/AIDS. PMID:26892323

Background During the earlier years of the HIV/AIDS epidemic, initial reports described sensorineural hearing loss in up to 49% of individuals with HIV/AIDS. During those years, patients commonly progressed to advanced stages of HIV disease, and frequently had neurological complications. However, the abnormalities on pure-tone audiometry and brainstem evoked responses outlined in small studies were not always consistently correlated with advanced stages of HIV/AIDS. Moreover, these studies could not exclude the confounding effect of concurrent opportunistic infections and syphilis. Additional reports also have indicated that some antiretroviral (ARV) medications may be ototoxic, thus it has been difficult to make conclusions regarding the cause of changes in hearing function in HIV-infected patients. More recently, accelerated aging has been suggested as a potential explanation for the disproportionate increase in complications of aging described in many HIV-infected patients, hence accelerated aging associated hearing loss may also be playing a role in these patients. Methods We conducted a large cross-sectional analysis of hearing function in over 300 patients with HIV-1 infection and in 137 HIV-uninfected controls. HIV-infected participants and HIV-uninfected controls underwent a two-hour battery of hearing tests including the Hearing Handicap Inventory, standard audiometric pure-tone air and bone conduction testing, tympanometric testing and speech reception and discrimination testing. Results Three-way ANOVA and logistic regression analysis of 278 eligible HIV-infected subjects stratified by disease stage in early HIV disease (n= 127) and late HIV disease (n=148) and 120 eligible HIV-uninfected controls revealed no statistical significant differences among the three study groups in either overall 4-PTA or hearing loss prevalence in either ear. Three-way ANOVA showed significant differences in word recognition scores (WRS) in the right ear among groups; a

42 middle-aged and older adults, ranging in age from 51 to 85 years, completed 10 items dealing with the assessment of knowledge regarding laws regulating issues related to HIV and AIDS. Participants also completed 40 items involving knowledge of risks for HIV infection. The Cronbach coefficient alpha and test-retest reliability coefficient on the HIV/AIDS and the Law Scale were .74 and .83, respectively. Over-all, the grand mean for correct answers was 46.9%, whereas the grand means for incorrect answers and "don't know" responses were 13.6% and 39.5%, suggesting substantial lack of knowledge of laws regulating issues related to HIV and AIDS. Women (50%) and younger participants (51 to 66 years old; 48.2%) showed more of this knowledge (50%) than men (43.0%) and older participants (46.2%). The sample reported a substantial amount of knowledge regarding HIV transmission assessed with factual (92.2% correct) and misconception (87.5% correct) items. The correlation between this knowledge and knowledge of laws regulating issues related to HIV and AIDS was .42 (p < .01). Research with this scale using adolescents and young adults as well as the utility of the scale in areas of clinical, legal, and policy development are discussed.

This paper on drug use and HIV/AIDS in China follows on from the column's May 2005 article on the description of the first methadone maintenance clinic in Beijing. Methadone maintenance clinics and needle exchange programmes are now being implemented in China as a response to the rapid increase in prevalence of HIV/AIDS over the last 10-15 years. It is worth noting that in prior years methadone was available only as for short-term detoxification from opioids and for research purposes. Accordingly, the Department of Health Education and Behavioural Intervention at the National Center for AIDS Prevention and Control in China plans to establish 1,000 methadone replacement clinics within the next 5 years to treat 200,000 heroin-dependent users who are at increased risk of HIV/AIDS. Robert Ali & Rachel HumeniukEditors, Asia Pacific ColumnThe cumulative number of registered drug users in mainland China increased from 70,000 in 1990 to 1.14 million in 2004. Heroin continues to be the most commonly used drug in China; however, polydrug use is popular among heroin users. Sedatives/hypnotics (e.g. triazolam) and other uncontrolled prescription opioids (e.g. pethidine and tramadol) are used commonly in combination with heroin. The majority of drug users (79%) are young people aged between 17 and 35 years and comprise predominantly farmers (30%) and unemployed people (45%). The HIV/AIDS epidemic in China has reached expansion phase (1995-present). It is estimated that the actual number of HIV/AIDS cases reached 840,000, including 80,000 actual AIDS patients, in 2003, with injecting drug users (IDUs) making up the largest proportion of these cases. Although the prevalence rate of HIV/AIDS is only 0.065% in the Chinese population overall, there is potential for an explosive spread of HIV/AIDS if preventative measures are not employed. Supported by the Chinese government and other related international organisations, harm reduction strategies such as methadone maintenance

The extent of the HIV pandemic-particularly in the hardest-hit countries, including South Africa-has prompted a call for greater engagement of all groups, including faith-based organisations (FBOs). Although FBOs are known to play a substantial role in providing care and support to those affected by HIV and AIDS, empirical evidence in regard to their actions in the broader context of stigma is limited. A qualitative, key-informant survey was conducted in South Africa as part of a six-country international study to examine perceptions of how FBOs have contributed to reduction in HIV risk, vulnerability and related impacts. The special emphasis of this paper is the influence of FBOs on stigma and discrimination. In-depth interviews were held with 34 senior-level key informants who act as key decision-makers in the response to HIV and AIDS in South Africa. Secular and faith-based respondents shared their perceptions of the faith-based response, including FBOs' actions in relation to HIV/AIDS stigma and discrimination. Our study revealed that while FBOs were perceived as taking some action to address stigma in South Africa, FBOs were also thought to contribute to HIV/AIDS- discrimination through conflating issues of sexuality and morality, and through associating HIV and AIDS with sin. The interviewees indicated a number of internal and external challenges faced by FBOs to deal effectively with stigma, including lack of information and skills, the difficulty of maintaining confidentiality in health services, and self-stigmatisation which prevents HIV-infected persons from revealing their status. Findings from this study may help both faith-based and secular groups capitalise on the perceived strengths of FBOs as well as to elucidate their perceived weaknesses so that these areas of concern can be further explored and addressed.

In 2003, a phase III placebo-controlled trial (VAX004) of a candidate HIV-1 vaccine (AIDSVAX B/B) was completed in 5,403 volunteers at high risk for HIV-1 infection from North America and the Netherlands. A total of 368 individuals became infected with HIV-1 during the trial. The envelope glycoprotein gene (gp120) from the HIV-1 subtype B viruses infecting 349 patients was sequenced from clinical samples taken as close as possible to the time of diagnosis, rendering a final data set of 1,047 sequences (1,032 from North America and 15 from the Netherlands). Here, we used these data in combination with other sequences available in public databases to assess HIV-1 variation as a function of vaccination treatment, geographic region, race, risk behavior, and viral load. Viral samples did not show any phylogenetic structure for any of these factors, but individuals with different viral loads showed significant differences (P = 0.009) in genetic diversity. The estimated time of emergence of HIV-1 subtype B was 1966–1970. Despite the fact that the number of AIDS cases has decreased in North America since the early 90s, HIV-1 genetic diversity seems to have remained almost constant over time. This study represents one of the largest molecular epidemiologic surveys of viruses responsible for new HIV-1 infections in North America and could help the selection of epidemiologically representative vaccine antigens to include in the next generation of candidate HIV-1 vaccines.

Unlike most infectious diseases in Africa, HIV/AIDS affects the urban elite as well as the rural poor, and generally during their most economically productive years. An increase in deaths among young adults of the magnitude predicted is likely to have substantial adverse effects on economic, political, and military/security stability throughout Africa. AIDS is causing increased stress on fragile African economic infrastructures as labor productivity declines, particularly in agricultural, labor-dependent economies. AIDS is causing obstacles to trade, foreign investment and tourism. Health systems and social coping mechanisms already are overburdened. High rates of HIV infection among police and military personnel threaten internal security. Furthermore, the demobilization of military forces in Africa may exacerbate the epidemic when HIV-infected soldiers return home and spread the virus. This presentation will illustrate why African AIDS Programs must be expanded to mitigate the multisectoral impact of the epidemic while preserving its spread.
In response to the need for HIV/AIDS and sexually transmitted disease (STD) information and support among seafarers, a regional project involving train-the-trainer workshops are being implemented in Vanuatu, Fiji Islands, Tuvalu, Solomon Islands, Tonga, Kiribati, Samoa, Federated States of Micronesia, Marshall Islands, and in Kavieng, Papua New Guinea. The project aims to build the capacity of the maritime training schools and partner agencies to provide high quality HIV/AIDS and STD training through the regional maritime training schools and colleges. In addition, the workshops aim to provide comprehensive information about HIV/AIDS and STDs and to further develop the training and education skills of participants. Condom is the main topic of the lectures, discussions, group works, brainstorms, role plays, questions and answers, games, participant presentations, and film showings. Informal feedback and formal evaluation on the workshops delivered have been excellent.
Since our last review, there have been new developments in several jurisdictions in the area of HIV/AIDS and prisons. This column reviews some important developments in Canada and in the US: the results of the evaluation of HIV/AIDS harm-reduction measures in the Canadian federal prison system; another Canadian inmate's fight for methadone maintenance treatment in prison; an important article on health care in Canadian prisons which states that there is little evidence that the federal prison system "is making any serious effort to provide treatment to any drug users"; the US Supreme Court's refusal to review a lower court's ruling permitting Alabama prisons to segregate HIV-positive inmates; an important ruling stating that inmates are entitled to receive medications in jail without interruption; and research showing that women inmates in the US are 23 times more likely to have AIDS than women in the general population.

The spectrum of complications emerging in successfully treated HIV-infected patients has dramatically changed since the advent of HAART. Typical AIDS-defining illnesses have been substituted by new comorbid conditions that threaten even those patients who maintain virologic suppression. Proper management of cardiovascular risk, and early diagnosis of AIDS-related and, particularly, non-AIDS-related malignancies (including papilomavirus-related neoplasms) must be introduced into the routine of care. Hot areas of investigation include HIV-associated neurocognitive disorders, hepatitis B and C coinfection, non-alcoholic fatty liver disease, progressive multifocal leukoencephalopathy and tuberculosis. Bone and kidney long-term toxicities and lipoatrophy remain as issues of paramount importance. The identification and early treatment of immune reconstitution disease is also of major interest, specially in those patients starting their antiretroviral treatment with severe CD4 cell depletion. The present review focuses on these twelve areas of increasing interest for physicians currently facing successfully treated HIV+ patients.

An evolving dominance of human immunodeficiency virus type 1 subtype C (HIV-1C) in the AIDS epidemic has been associated with a high prevalence of HIV-1C infection in the southern African countries and with an expanding epidemic in India and China. Understanding the molecular phylogeny and genetic diversity of HIV-1C viruses may be important for the design and evaluation of an HIV vaccine for ultimate use in the developing world. In this study we analyzed the phylogenetic relationships (i) between 73 non-recombinant HIV-1C near-full-length genome sequences, including 51 isolates from Botswana; (ii) between HIV-1C consensus sequences that represent different geographic subsets; and (iii) between specific isolates and consensus sequences. Based on the phylogenetic analyses of 73 near-full-length genomes, 16 "lineages" (a term that is used hereafter for discussion purposes and does not imply taxonomic standing) were identified within HIV-1C. The lineages were supported by high bootstrap values in maximum-parsimony and neighbor-joining analyses and were confirmed by the maximum-likelihood method. The nucleotide diversity between the 73 HIV-1C isolates (mean value of 8.93%; range, 2.9 to 11.7%) was significantly higher than the diversity of the samples to the consensus sequence (mean value of 4.86%; range, 3.3 to 7.2%, P < 0.0001). The translated amino acid distances to the consensus sequence were significantly lower than distances between samples within all HIV-1C proteins. The consensus sequences of HIV-1C proteins accompanied by amino acid frequencies were presented (that of Gag is presented in this work; those of Pol, Vif, Vpr, Tat, Rev, Vpu, Env, and Nef are presented elsewhere [http://www.aids.harvard.edu/lab_research/concensus_sequence.htm]). Additionally, in the promoter region three NF-kappa B sites (GGGRNNYYCC) were identified within the consensus sequences of the entire set or any subset of HIV-1C isolates. This study suggests that the consensus sequence

Describing the results of a study on the impact of HIV on practitional dentistry, the author finds out a considerable uncertainty of knowledge among elder practitioners. While 62% are willing to treat HIV-infected persons, a big part of the participants is looking on AIDS as an occupational risk. Regarding infection control procedures, the results show a limited compliance with the generally accepted recommendations.

The National AIDS Control Organization (NACO) of India had estimated, before this year, that there were 5.134 million HIV positive people in India at the end of 2004 and that they were increasing at the rate of more than a quarter of a million people every year. In a recent publication, we estimated that, if the number of reported AIDS cases in India are only 50% efficient, i.e. if the number of actual AIDS cases in India is no more than twice the reported number, then the number of HIV positive people in India should have been no more than 2.5 million at the end of 2004. Many other people in the epidemiology community have the same point of view. Now, the government of India is also of the same view and "The latest data released by the government shows that the country has around 2 to 3 million people with HIV, much lower than last year's figure of 5.7 million". However, our assumption that the actual number of AIDS cases in India is only about twice the number reported, has been questioned, and it has been suggested that the Indian system of AIDS reporting is woefully inaccurate and the actual number of AIDS cases there could be three, four or even five times the reported number. In this paper, we consider this suggestion and show that, even if the actual number of AIDS cases was three, four, or even five, times the reported number, the number of HIV positive people in India, at the end of 2004, should still be no more than 2.5 million. This is because our previous estimate was an over estimate and had room to accommodate considerably more number of AIDS cases. We also estimate the number of AIDS deaths in India and show that it should be considerably less than those estimated by the World Health Organisation (WHO).

Purpose: The purpose of this paper is to show that HIV/AIDS-related stigma has persisted world-wide for decades. However, studies on the linkage between stigmatizing attitudes towards people living with HIV/AIDS (PLWHA) and misconceptions about HIV transmission routes in the general population, especially among youth in China, are sparse--a gap…

Drug therapy is a vital component of the care required to promote quality of life for individuals who are afflicted with HIV or AIDS. Issues including weight loss and gain, heart disease, insulin resistance, and even increased bone metabolism must be considered when determining appropriate pharmacologic therapy. New complications often arise with new treatments; living longer may not always mean living better. However, it is the responsibility of nurses to promote the best care possible. Management of appropriate drug therapy and the related implications are critical nursing responsibilities in the care of individuals who have HIV or AIDS.

Education has long been identified as having a key role to play in reducing HIV-related risk and vulnerability, and in mitigating the impact of the epidemic on affected individuals and communities. This article reflects on progress over a 30-year period with respect to older and more emergent forms of education concerning HIV and AIDS: treatment education, education for HIV prevention, and education to encourage a positive and supportive community response. It points to a number of priorities for the future. These include analyzing more carefully different forms of HIV-related education, their consequences and effects, and identifying the specific effectivity of education in general and HIV-related education in particular in achieving positive outcomes. The potential of education to enable new ways of seeing, understanding, and hoping is stressed, as is the need to support education processes and systems that "think" faster than the epidemic.

Since the introduction of highly active retroviral therapy (HAART) in 1996, dramatic improvements in therapeutic treatment modalities for HIV type 1 (HIV-1) infection have occurred. Potent drug combinations in HAART regimens efficiently block HIV-1 replication in most patients; however, multiple shortcomings of HAART are apparent and require novel treatments that can be utilized in combination with HAART or as stand-alone therapies. Gene therapy of HIV-1 represents one such treatment and several strategies are currently under development. This review focuses on advancements in the gene therapy of HIV/AIDS by highlighting the progress made in selecting new therapeutic targets and developing novel tools to exert an effect on these targets. In addition, new trends emerging from this progress are summarized. This review is based primarily on literature published between 2006 and 2008.

Live-attenuated viruses used in vaccines can regain their virulence, which for deadly viruses such as HIV is an unacceptable risk. Now, attenuated HIV-1 viruses, which include mutations that genetically encode unnatural amino acids and prevent them from replicating in normal cells, have been constructed.

An article focuses on the influence of social marketing, particularly of condoms and efforts to fight the HIV/AIDS epidemic. Condom sales have increased, especially in Africa. These sales are a good reflection of condoms purchased and used. Concerning the prevention of HIV/AIDS, availability of condoms is the most significant achievement of condom social marketing programs; however, HIV/AIDS prevalence has not declined. The marketing of condoms has been observed to be insufficient compared to the theoretical demand for condoms. All social marketing programs should be focused on marketing and communications, expressing messages that promote safer sexual behavior. Products and services aimed at safe sexual activity are being searched as tools in the fight against AIDS. In Uganda for instance, a kit called "Clear Seven" includes a large dose of pyprofloxin, a seven-day course of doxycycline, seven condoms and partner referral cards. The Population Services International is doing voluntary counseling and testing in Zimbabwe to prevent HIV transmission and contribute to destigmatizing people living with AIDS. It is too soon to assess the effectiveness of the program, yet many countries are already planning to duplicate it.

The prevention and control of HIV/AIDS is a social as well as a public health issue. This approach is reflected in new policy initiatives developed by the Government of India's National AIDS Control Organization in 1997. Future strategies will be based on a multisectoral, partnership-oriented approach. Bilateral agencies are encouraged to establish interventions in areas such as sexually transmitted disease (STD) control, condom distribution, counseling, health care, and hospice care. Special campaigns focused on youth and adolescents, including the inclusion of HIV/AIDS in the school curriculum, are planned. New strategies will be developed to address the HIV risk associated with drug abuse. The home- and community-based care of HIV/AIDS patients will be promoted, with emphasis on emotional and social support needs. Other areas to be addressed include the integration of STD control with primary health care, a blood transfusion policy, education for commercial sex workers, an end to discrimination against people with AIDS, and expansion of the national sentinel surveillance system.

Despite the seriousness of the HIV epidemic globally, and in South Africa in particular, little is known about how HIV/AIDS affects disabled people. One important and little explored area is the role that organisations that represent disabled people or that work on behalf of disabled people, are playing in addressing the HIV/AIDS epidemic among the disabled people they represent or serve. This paper presents the findings of a nationwide survey of disability organisations in South Africa. The purpose of this study was to explore the role of disability organisations in addressing the HIV epidemic among disabled people in South Africa. The findings suggest that while organisations recognise the importance of providing HIV education, and many have taken steps to do so, disabled people are largely excluded from general HIV prevention messages. Disabled people also have significant difficulties in accessing general health care, relevant for HIV testing and treatment. In a country trying to manage serious social problems with limited resources, this paper highlights the need for increased cooperation and collaboration between relevant parties in order to facilitate the changes necessary for disabled people to access needed health information and care.

Networks of concurrent sexual partnerships may be the primary cause of epidemic spread of HIV-1 in parts of sub-Saharan Africa. This pattern of sexual behaviour increases the likelihood that individuals experiencing primary HIV-1 infection transmit the virus to other persons. Networks of concurrent partnerships are likely to be important in both the early ('epidemic') and late ('endemic') phases of HIV-1 transmission. Interventions should aim to break the sexual networks, whatever the stage of the epidemic. However, prevention of transmission in the endemic phase also requires a greater awareness of early clinical manifestations of HIV-1 infection in the general population. Such awareness, coupled with the availability of condoms and access to HIV-1 testing facilities, may reduce transmission in discordant couples.

Physicians' response to acquired immune deficiency syndrome (AIDS) is poorly understood and often attributed to fear of human immunodeficiency virus (HIV) infection through occupational exposure. We surveyed 268 physicians from three geographic regions in North American with different specialties and responsibilities for HIV-positive patients. An important difference was found between the published risk and the physicians' perceived risk of infection after a single occupational exposure. Almost half of the respondents stated that they feared contracting AIDS more than other diseases. The physicians who perceived themselves to be at high physical risk were more likely than the others to report that AIDS had changed the way they interact with their patients (r = 0.26, p less than 0.001). No relation was found between the perception of physical risk and the number of HIV-infected patients (r = -0.07, p = 0.15). However, the perception of social risk showed a small inverse correlation (r = -0.15, p less than 0.02), in which the physicians with more HIV-infected patients reported less concern about negative social consequences. The physicians who perceived themselves to be at high personal risk were more likely than the others to report that surgeons have the right to refuse patients who do not wish to undergo HIV antibody testing (r = -0.16, p less than 0.01 for physical risk; r = -0.29, p less than 0.001 for social risk). Multiple regression analyses indicated that physicians' perception of physical risk was not related to age or sex but was modestly related to income source. The perception of social risk was related to sex and income source. Physicians' perception of personal risk is a crucial, yet often unacknowledged, component of the fight against AIDS. Our findings suggest that lack of attention to this issue is seriously compromising initiatives designed to facilitate physician participation in AIDS care. PMID:2207904

This study was conducted to better understand the prognostic factors influencing the disease progression and mortality in patients with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) in a high-middle-income country. This registry-based retrospective cohort study was conducted in Tehran from April 2004 to March 2014. We enrolled 2473 HIV-infected patients who had a medical record in Behavioral Diseases Counseling Centers. The outcomes of interest were the estimation of time: (1) from HIV diagnosis to AIDS progression and (2) from AIDS to AIDS-related death. The 1-year, 5-year, and 10-year probability of disease progression from HIV diagnosis to AIDS was 45.0%, 69.9%, and 90.4%, and that of AIDS-related death was 17.2%, 30.3%, and 39.2%, respectively. Multivariate Cox regression analysis indicated that AIDS progression was significantly associated with male sex (P = 0.022), an increase in age (P = 0.001), low educational levels (P = 0.001), and a decreased level of CD4 cell count (P = 0.001). Furthermore, the AIDS-related mortality was significantly associated with male sex (P = 0.010), tuberculosis coinfection (P = 0.001), and antiretroviral therapy (P = 0.001). The results of this study indicated that progression to AIDS and AIDS-related death is affected by several modifiable and non-modifiable predictors. We indicated that a substantial proportion of the HIV-positive people were unaware of their status and were diagnosed very late. This hidden source of HIV infection had the opportunity to transmit the infection to other people.

HIV/AIDS infections are growing at an alarming rate for young adults. In 2009, youth, ages 13-29, accounted for 39% of all new HIV infections in the U.S. (Division of HIV/ AIDS Prevention, Centers for Disease Control (CDC), 2011). South Carolina ranks eighth in the nation for new HIV cases, while the capital city of Columbia ranks seventh…

The AIDS Litigation Project has reviewed nearly 600 reported cases involving individuals with human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS) in the federal and state courts in the United States between 1991 and 1997. Cases were identified through a federal and 50-state computer and library search. An important subset of litigation relates to HIV/AIDS in the public health and health care systems, since the law affects health care institutions and professionals, patients, and public health policy in America. This subset of HIV/AIDS litigation includes testing and reporting; privacy, the duty to warn, and the right to know; physician standards of care in prevention and treatment; and discrimination and access to health care. In broad terms, the review demonstrates a reliance on voluntary testing and protection of patient privacy through HIV-specific statutes and the common law. Negligence with potential civil and criminal liability has been alleged in cases of erroneous or missed diagnosis of HIV infection. In the first AIDS case to be considered by the Supreme Court, the Court will decide whether patients with asymptomatic HIV infection are protected under the Americans With Disabilities Act. Considerable progress has been made, both socially and legally, during the first 2 decades of the epidemic, but much still needs to be accomplished to protect privacy, prevent discrimination, and promote tolerance.

The seroprevalence of toxoplasmosis among 505 of human immunodeficiency virus (HIV)/AIDS patients was 226 (44.8%; 95% CI 42.64-51.76): 27 (47.4%) and 199 (44.4%) showed Toxoplasma seropositivity with and without toxoplasmic encephalitis (TE), respectively (P <0.05). The majority of these patients were in the 25-34 age group (44 versus 39%), male (86 versus 76%), and Chinese (49 versus 53%), though no statistical significance was found between the two. Significant differences between these two groups were noted, however, in terms of marital status, occupation, and present address. The heterosexual exhibited the most frequent behavior at risk for HIV infection, and accounted for 51 and 59% of patients with and without TE, respectively. Only 17/260 (6.5%) and 1/137 (0.7%) of them later acquired TE after receiving primary chemoprophylaxis (cotrimoxazole) and antiretroviral therapy including HAART (P <0.05). Fifty-seven (11.3%) out of those 505 patients were diagnosed with AIDS-related TE. The most common clinical manifestation was headache (56%). The computed tomography scan findings showed most lesions to be multiple (96.4%), hypodense (66.7%), and in the parietal region (39.3%). Twenty-seven (47.4%) patients had chronic (latent) Toxoplasma infection as evidenced by seropositivity for anti-Toxoplasma (IgG) antibody. At the time of diagnosis, the range of CD4 cell count was from 0-239 with a median of 25 cells/cumm. We also found that a CD4 count of less than 100 cells/cumm was significantly associated with development of TE (P <0.05). Clinical outcomes showed that among those who survived, 21 (36.8%), 16 (28.1%), and 2 (3.5%) of patients had completed treatment, transferred out, and were lost to follow up, respectively. Unfortunately, 18 (31.6%) of the cases were officially pronounced dead. Overall, 7 (12.3%) patients were detected as recurrent TE in this study.

Background The motivation for this paper is to inform the selection of future policy directions for tackling HIV/AIDS in Russia. The Russian Federation has more people living with HIV/AIDS than any other country in Europe, and nearly 70% of the known infections in Eastern Europe and Central Asia. The epidemic is particularly young, with 80% of those infected aged less than thirty, and no Russian region has escaped the detection of infections. However, measures to address the epidemic in Russia have been hampered by late recognition of the scale of the problem, poor data on HIV prevalence, potentially counterproductive narcotics legislation, and competing health priorities. An additional complication has been the relative lack of research into the spatial heterogeneity of the Russian HIV/AIDS epidemic, investigating the variety of prevalence rates in the constituent regions and questioning assumptions about the links between the epidemic and the circumstances of post-Soviet transformation. In the light of these recent developments, this paper presents research into the determinants of regional HIV prevalence levels in Russia. Results Statistical empirical research on HIV and other infectious diseases has identified a variety of factors that influence the spread and development of these diseases. In our empirical analysis of determinants of HIV prevalence in Russia at the regional level, we identify factors that are statistically related to the level of HIV prevalence in Russian regions, and obtain some indication of the relative importance of these factors. We estimate an empirical model that includes factors which describe economic and socio-cultural characteristics. Conclusion Our analysis statistically identifies four main factors that influence HIV prevalence in Russian regions. Given the different nature of the factors that we identify to be of importance, we conclude that successful HIV intervention policies will need to be multidisciplinary in nature. Finally

The emergence of HIV-1 group M subtype B in North American men who have sex with men (MSM) was a key turning point in the HIV/AIDS pandemic. Phylogenetic studies have suggested cryptic subtype B circulation in the United States (US) throughout the 1970s2,3 and an even older presence in the Caribbean3. However, these timing and geographical inferences, based upon partial HIV-1 genomes that postdate the recognition of AIDS in 1981, remain contentious1,4 and the earliest movements of the virus within the US are unknown. We serologically screened >2000 1970s serum samples and developed a highly sensitive new approach for recovering viral RNA from degraded archival samples. Here, we report eight coding-complete genomes from US serum samples from 1978-79 – eight of the nine oldest HIV-1 group M genomes to date. This early, full-genome ‘snapshot’ reveals the US HIV-1 epidemic exhibited surprisingly extensive genetic diversity in the 1970s but also provides strong evidence of its emergence from a pre-existing Caribbean epidemic. Bayesian phylogenetic analyses estimate the jump to the US at ~1970 and place the ancestral US virus in New York City with 0.99 posterior probability support, strongly suggesting this was the crucial hub of early US HIV/AIDS diversification. Logistic growth coalescent models reveal epidemic doubling times of 0.86 and 1.12 years for the US and Caribbean, respectively, suggesting rapid early expansion in each location1. Comparisons with more recent data reveal many of these insights to be unattainable without archival, full-genome sequences. We also recovered the HIV-1 genome from the individual known as ‘Patient 0’5 and show there is neither biological nor historical evidence he was the primary case in the US or for subtype B as a whole. We discuss the genesis and persistence of this belief in the light of these evolutionary insights. PMID:27783600

In Swaziland, a polygamous society in Southern Africa, the prevalence of the human immune virus/acquired immune deficiency syndrome (HIV/AIDS) is continuing to proliferate at an alarming rate. In 1992 the prevalence rate was 3.9%. However in 12 years, by 2004, the prevalence rate had reached 42.6%. This article explores some of the traditional cultural practices and experiences that increase Swazi women's vulnerability to HIV/AIDS. The traditional cultural practices fall into four categories: (1) socialization and the roles of women, (2) the minority status of women, (3) the practice of a dowry, and (4) the wife as an inheritance. The women's experiences include the Swazi men's beliefs in the virginity cure myth, the women's extreme poverty, and the Swazi men who are migrant workers in neighboring states. This article concludes with recommendations for public policy and for future research within the context of Swazi culture.

The discovery of the human immunodeficiency virus (HIV) as the causative organism of acquired immunodeficiency syndrome (AIDS) and the inability of modern medicine to find a cure for it has placed HIV as one of the most dreaded pathogens of the 21st century. With millions of people infected with HIV, it was once thought to result in “medical apocalypse”. However, with the advent of antiretroviral therapy (ART), it is now possible to control HIV. Adherence to ART helps to keep the viral load under control and prolong the time of progression to AIDS, resulting in near normal life expectancy. Even with the introduction of ART, a substantial number of patients fail to adhere due to a variety of reasons, including adverse side effects, drug abuse, mental disorders, socioeconomic status, literacy, and social stigma. With the availability of so many options for HIV treatment at each stage of the disease progression, physicians can switch between the treatment regimens to avoid and/or minimize the adverse effects of drugs. Close monitoring, major social reforms, and adequate counselling should also be implemented to circumvent other challenges. PMID:27054050

HIV-1 disrupts the homeostatic equilibrium between the host and coinfecting microbes, facilitating reactivation of persistent viruses and invasion by new viruses. These viruses usually accelerate HIV disease but occasionally create conditions detrimental for HIV-1. Understanding these phenomena may lead to anti-HIV-1 strategies that specifically target interactions between HIV-1 and coinfecting viruses.

Adolescents and young adults in sub-Saharan Africa (SSA) are particularly vulnerable to human immunodeficiency virus (HIV) and acquired immune deficiency syndrome (AIDS) infection. Adolescents orphaned as a direct result of HIV/AIDS are at an elevated risk of acquiring HIV/AIDS and other sexually transmitted infections. However, limited empirical evidence exists on HIV knowledge and prevention programs, especially those designed to address HIV information gaps among adolescents. This study evaluates the effect of a peer mentorship program provided in addition to other supportive services on HIV/AIDS knowledge, beliefs, and prevention attitudes, among school-going orphaned adolescents in southern Uganda. We utilize data from the Bridges to the Future Study, a 5-year longitudinal randomized experimental study funded by the National Institute of Child Health and Human Development. Out of the 1410 adolescents enrolled in the study (average age = 12.7 at study initiation), 855 of them participated in a nine-session, curriculum based peer mentorship program. We analyzed data collected at baseline and 12-months post intervention initiation. The results from bivariate and regression analysis indicate that, controlling for socioeconomic characteristics, adolescents who participated in a peer mentorship program were more likely than non-participants to report increased scores on HIV/AIDS knowledge(b = .86, 95%CI = .47 – 1.3, p ≤ .001); better scores on desired HIV/AIDS-related beliefs (b = .29, 95%CI = .06 – .52, p ≤ .01); and better scores on HIV/AIDS prevention attitudes (b = .76, 95%CI = .16 – 1.4, p ≤ .01). Overall, the study findings point to the potential role a of peer mentorship program in promoting the much-desired HIV/AIDS knowledge, beliefs, and prevention attitudes among orphaned adolescents. Future programs and policies that support AIDS-orphaned adolescents in sub-Saharan Africa should consider incorporating peer mentoring programs that provide
Background Human immunodeficiency virus type 1(HIV-1) infects and activates innate immune cells in the brain resulting in inflammation and neuronal death with accompanying neurological deficits. Induction of inflammasomes causes cleavage and release of IL-1β and IL-18, representing pathogenic processes that underlie inflammatory diseases although their contribution HIV-associated brain disease is unknown. Results Investigation of inflammasome-associated genes revealed that IL-1β, IL-18 and caspase-1 were induced in brains of HIV-infected persons and detected in brain microglial cells. HIV-1 infection induced pro-IL-1β in human microglia at 4 hr post-infection with peak IL-1β release at 24 hr, which was accompanied by intracellular ASC translocation and caspase-1 activation. HIV-dependent release of IL-1β from a human macrophage cell line, THP-1, was inhibited by NLRP3 deficiency and high extracellular [K+]. Exposure of microglia to HIV-1 gp120 caused IL-1β production and similarly, HIV-1 envelope pseudotyped viral particles induced IL-1β release, unlike VSV-G pseudotyped particles. Infection of cultured feline macrophages by the related lentivirus, feline immunodeficiency virus (FIV), also resulted in the prompt induction of IL-1β. In vivo FIV infection activated multiple inflammasome-associated genes in microglia, which was accompanied by neuronal loss in cerebral cortex and neurological deficits. Multivariate analyses of data from FIV-infected and uninfected animals disclosed that IL-1β, NLRP3 and caspase-1 expression in cerebral cortex represented key molecular determinants of neurological deficits. Conclusions NLRP3 inflammasome activation was an early and integral aspect of lentivirus infection of microglia, which was associated with lentivirus-induced brain disease. Inflammasome activation in the brain might represent a potential target for therapeutic interventions in HIV/AIDS. PMID:24886384

Genomic studies involving well-defined multicenter cohorts of HIV-1/AIDS covering multiple populations have led to a greater understanding of the role of host determinants in viral acquisition, disease progression, transmission, and response to anti-retroviral therapy. Similarly, recent knowledge on the virus genetic diversity has helped in elucidating mechanisms leading to the evolution of viral escape mutants and the role played by host immune determinants, in particular the major histocompatibility complex (MHC) associated genes. At least two alleles, HLA-B*27 and B*57, have been identified as 'protective' against HIV-1 while B*35 and B*53 act as susceptibility favoring factors. How human leukocyte antigen (HLA)-mediated selection drives the evolution of HIV-1 and which circulating variants are more likely to evade immune surveillance of the population are now beginning to become clear. Importantly, the rare HLA alleles in a population bear a selective advantage to the host because these can induce immune responses against pre-adapted viruses. It is conceivable that previously established protective HLA associations are shifting with the evolving cytotoxic T lymphocyte (CTL) epitopes and may not remain protective in future. At the same time, this process is unraveling novel sub-dominant epitopes of the virus which could now be incorporated as the dominant target CTL epitopes. An insight into the population-specific correlates of protection is hence necessary for designing future anti-HIV therapeutic and/or prophylactic vaccine formulation(s).

The effectiveness of education in reducing high-risk human immunodeficiency virus (HIV) transmission behaviors was examined in 313 injection drug users. Involvement in high-risk behaviors was assessed via structured interview at study entry and 4 months following the intervention. Subjects were randomly assigned to (1) AIDS education, (2) AIDS education with optional HIV antibody testing, or (3) a wait list. The sample as a whole decreased its involvement in high-risk behaviors, but there were no significant differences as a function of experimental group assignment. PMID:1546776

Viruses have developed strategies to counteract signalling through Toll-like receptors (TLRs) that are involved in the detection of viruses and induction of proinflammatory cytokines and IFNs. Vaccinia virus (VACV) encodes A46 protein which disrupts TLR signalling by interfering with TLR: adaptor interactions. Since the innate immune response to viruses is critical to induce protective immunity, we studied whether deletion of A46R gene in a NYVAC vector expressing HIV-1 Env, Gag, Pol and Nef antigens (NYVAC-C) improves immune responses against HIV-1 antigens. This question was examined in human macrophages and in mice infected with a single A46R deletion mutant of the vaccine candidate NYVAC-C (NYVAC-C-ΔA46R). The viral gene A46R is not required for virus replication in primary chicken embryo fibroblast (CEF) cells and its deletion in NYVAC-C markedly increases TNF, IL-6 and IL-8 secretion by human macrophages. Analysis of the immune responses elicited in BALB/c mice after DNA prime/NYVAC boost immunization shows that deletion of A46R improves the magnitude of the HIV-1-specific CD4 and CD8 T cell immune responses during adaptive and memory phases, maintains the functional profile observed with the parental NYVAC-C and enhances anti-gp120 humoral response during the memory phase. These findings establish the immunological role of VACV A46R on innate immune responses of macrophages in vitro and antigen-specific T and B cell immune responses in vivo and suggest that deletion of viral inhibitors of TLR signalling is a useful approach for the improvement of poxvirus-based vaccine candidates.

Identification of human immunodeficiency virus type 1 (HIV-1)-infected individuals is of paramount importance for the control of the spread of AIDS worldwide. Currently, the vast majority of screening centers throughout the world rely on serological techniques. As such, clinically asymptomatic but HIV-infected, seronegative individuals are rarely identified. In this report we show that 18% (30/165) of seronegative individuals who were considered to be a unique cohort of patients at high risk for HIV infection had circulating B cells that, upon in vitro polyclonal activation with pokeweed mitogen, produced antibodies reactive with HIV. Furthermore, polymerase chain reaction analysis of DNA obtained from aliquots of the peripheral blood mononuclear cells from these seronegative but pokeweed mitogen assay-positive individuals tested revealed the presence of HIV-specific sequences in a significant number of samples. In addition, depletion of CD8+ T cells from peripheral blood mononuclear cells of HIV-1-seronegative individuals prior to in vitro culture with pokeweed mitogen resulted in increased sensitivity for detecting HIV-reactive antibodies. This assay has obvious epidemiological implications, especially in the case of high-risk groups, and also provides a simple technique to enhance detection of HIV-infected individuals. Of further interest is the determination of the mechanisms related to the lack of HIV-specific antibodies in the serum of these infected individuals. Images PMID:2111024
Toxoplasmosis has historically been considered one of the most important opportunistic infections detected in HIV/AIDS patients. The prevalence rates of latent Toxoplasma infections in HIV-infected patients has been found to vary greatly from 3% to 97%. Prevalence has been found to be related to ethnicity, certain risk factors, and reactivation of toxoplasmosis. Prior to antiretroviral therapy, toxoplasmic encephalitis (TE) was the most common focal cerebral lesion detected in AIDS patients with Toxoplasma infection, occurring in approximately half of Toxoplasma-seropositive patients. Other forms of dissemination have also been reported in AIDS patients in sites such as the eyes, lungs, heart and spinal cord. Anti-Toxoplasma therapy and chemoprophylaxis have shown effectiveness in reducing the incidence of TE, while noncompliance has been identified as a cause of relapse in these settings. Toxoplasmosis is one of the most common neuropathological complications found at autopsy. Rapid progress in the development of highly active antiretroviral therapy (HAART) has changed the observed patterns with TE, for which there has been a marked decrease in overall incidence. Subsequently, TE has been found to be significantly associated with the so-called "neurological immune restoration inflammatory syndrome" (NIRIS). Toxoplasma screening programs are recommended for all newly diagnosed HIV-positive patients. Chemoprophylaxis should be considered in HIV-infected patients who have a CD4 < 200 cells/mm3, particularly in settings where resources are limited and there is not access to HAART. TE remains a cause of morbidity and mortality among AIDS patients.

Although fears are part of normal development, the living environment of HIV/AIDS affected children is conducive to the development of particular fears. This study examined the fears of 39 South African children (7-13 years) living in a low socioeconomic community with a high prevalence of HIV/AIDS. The aim was to consider if these children were a special population with regard to their fears. The Free Option Method was used to identify the children's fears. Data were analyzed by means of a priori thematic analysis, followed by a qualitative analysis. The expressed fears could be described with fear categories previously reported by normative samples. The wild animal category and specifically snake fears were reported most. The second analysis revealed a substantial minority of fears reflecting life in the South African HIV/AIDS affected context. It was concluded that the children represented a normative population who experienced particular fears due to their special circumstances. Further investigation of HIV/AIDS affected children's fears and related psychological issues is recommended.

The purpose of this paper is to report on characteristics of journals that publish manuscripts in the HIV/AIDS behavioural science realm, with the goal of providing assistance to authors seeking to disseminate their work in the most appropriate outlet. Fifty journals who publish behavioural research on HIV/AIDS in English were identified through library and electronic searches. Although ten of the journals focused specifically on HIV/AIDS, the majority of journals are in related fields, including health psychology/behavioural medicine, sexual behaviour, substance abuse, public health/prevention or general medicine. Acceptance rates ranged from 8- 89% with a mean acceptance rate of 39%. Reported review times ranged from 1-12 months with three months the mode, while publication lag following acceptance averages six months. Acceptance rates were related to impact factors, with more selective journals evidencing higher impact factors. The variety of publication outlets available to authors of HIV/AIDS behavioral science studies creates ample opportunity for dissemination, as well as challenge for readers in discerning the quality of published work.
The province of Papua, Indonesia has one of the fastest growing rates of HIV infection in Asia. Within volatile political conditions, HIV has reached generalized epidemic status for indigenous Papuans. This article explores the merits of using the concept of local biologies as an analytic tool to assess the range of factors which affect a local pattern of untreated HIV and rapid onset of AIDS. A research team conducted 32 in-depth interviews with HIV-positive indigenous persons and 15 interviews with health care workers in urban and peri-urban sites in the central highlands region. The results show fear of gossip and stigmatization, regional political conditions and gaps in care interweave to create local biological conditions of evasion of care and rapid onset of AIDS. The normative emphasis in contemporary scholarship on stigma as shaping subjective responses to HIV needs to be complemented by a full assessment of the physiological impact of health services, and the ways political conditions trickle down and mediate local biological patterns. The concept of local biologies is highly effective for explaining the full scope of possible factors affecting the intersection of social and physical realms for HIV-positive persons.
The talk will discuss the application of the continuum theory of elastic shells to understand the different morphologies of Retroviral capsids. Minor differences in molecular structure between different capsid proteins produce large changes in capsid morphology. Continuum elasticity theory can account for the capsid shape ``phase-diagram.'' The conical shape of the capsid of the HIV virus is the result of assembly ``constraints'' in the form of the enclosing lipid bilayer and the osmotic pressure of the encapsidated genome molecules.

The interaction of gold nanoparticles (AuNP) with human immune-deficiency virus aspartic protease (HIVPR) is modelled using a regime of molecular dynamics simulations. The simulations of the ‘docking’, first as a rigid-body complex, and eventually through flexible-fit analysis, creates 36 different complexes from four initial orientations of the nanoparticle strategically positioned around the surface of the enzyme. The structural deviations of the enzymes from the initial x-ray crystal structure during each docking simulation are assessed by comparative analysis of secondary structural elements, root mean square deviations, B-factors, interactive bonding energies, dihedral angles, radius of gyration (R g), circular dichroism (CD), volume occupied by C α , electrostatic potentials, solvation energies and hydrophobicities. Normalisation of the data narrows the selection from the initial 36 to one ‘final’ probable structure. It is concluded that, after computer simulations on each of the 36 initial complexes incorporating the 12 different biophysical techniques, the top five complexes are the same no matter which technique is explored. The significance of the present work is an expansion of an earlier study on the molecular dynamic simulation for the interaction of HIVPR with silver nanoparticles. This work is supported by experimental evidence since the initial ‘orientation’ of the AgNP with the enzyme is the same as the ‘final’ AuNP-HIVPR complex generated in the present study. The findings will provide insight into the forces of the binding of the HIVPR to AuNP. It is anticipated that the protocol developed in this study will act as a standard process for the interaction of any nanoparticle with any biomedical target.

According to a national survey, almost two out of every three Canadians think the federal government should be spending more to fight HIV/AIDS. The survey also found that: (a) although most Canadians know a lot about HIV/AIDS, there are some significant gaps in their knowledge; and (b) although most Canadians think HIV/AIDS is a serious problem, the vast majority do not consider themselves to be at risk for HIV infection. Few Canadians blame people for contracting HIV through sex or drug use, but many Canadians are still uncomfortable associating with people with HIV/AIDS in certain settings.

Human immunodeficiency virus (HIV) infection is associated with the loss of the two principal types of dendritic cell (DC), myeloid DC (mDC) and plasmacytoid DC (pDC), but the mechanism of this loss and its relationship to AIDS pathogenesis remain ill-defined. The nonhuman primate is a powerful model to dissect this response for several reasons. Both DC subsets have been well characterized in nonhuman primates and shown to have strikingly similar phenotypic and functional characteristics to their counterparts in the human. Moreover, decline of mDC and pDC occurs in rhesus macaques with end-stage simian immunodeficiency virus (SIV) infection, the model of HIV infection in humans. In this brief review, we discuss what is known about DC subsets in pathogenic and nonpathogenic nonhuman primate models of HIV infection and highlight the advances and controversies that currently exist in the field.

Diarrhea is a common comorbidity present in patients with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) who are treated with highly active antiretroviral therapy. With a multifactorial etiology, this diarrhea often becomes difficult to manage. In addition, some antiretrovirals are associated with chronic diarrhea, which potentially creates an adherence barrier to antiretrovirals and may ultimately affect treatment outcomes and future therapeutic options for HIV. A predominant type of diarrhea that develops in HIV patients has secretory characteristics, including increased secretion of chloride ions and water into the intestinal lumen. One proposed mechanism that may lead to this type of secretory diarrhea is explained by the activation of the cystic fibrosis transmembrane conductance regulator and calcium-activated chloride channels. Crofelemer is a novel antidiarrheal agent that works by inhibiting both of these channels. The efficacy and safety of crofelemer has been evaluated in clinical trials for various types of secretory diarrhea, including cholera-related and acute infectious diarrhea. More recently, crofelemer was approved by the US Food and Drug Administration for the symptomatic relief of noninfectious diarrhea in adult patients with HIV/AIDS on antiretroviral therapy. Results from the ADVENT trial showed that crofelemer reduced symptoms of secretory diarrhea in HIV/AIDS patients. Because crofelemer is not systemically absorbed, this agent is well tolerated by patients, and in clinical trials it has been associated with minimal adverse events. Crofelemer has a unique mechanism of action, which may offer a more reliable treatment option for HIV patients who experience chronic secretory diarrhea from antiretroviral therapy. PMID:23888120

Background: Approximately 35 new HIV (Human Immunodeficiency Virus, HIV) cases and at least 1000 serious infections are transmitted annually to health care workers. In China, HIV prevalence is increasing and nursing personnel are encountering these individuals more than in the past. Contaminated needle-stick injuries represent a significant occupational burden for nurses. Evidence suggests that nurses in China may not fully understand HIV/AIDS (Acquired immunodeficiency syndrome, AIDS) and HIV-related occupational safety. At this time, universal protection precautions are not strictly implemented in Chinese hospitals. Lack of training may place nurses at risk for occupational exposure to blood-borne pathogens. Objectives: To assess the effectiveness of integrated interventions on nurses' knowledge improvement about reducing the risk of occupationally acquired HIV infection. Methods: We audited integrated interventions using 300 questionnaires collected from nurses at the Affiliated Hospital of Xiangnan University, a public polyclinic in Hunan Province. The intervention studied was multifaceted and included appropriate and targeted training content for hospital, department and individual levels. After three months of occupational safety integrated interventions, 234 participants who completed the program were assessed. Results: Of the subjects studied, 94.3% (283/300) were injured one or more times by medical sharp instruments or splashed by body fluids in the last year and 95.3% considered their risk of occupational exposure high or very high. After the intervention, awareness of HIV/AIDS-related knowledge improved significantly (χ² = 86.34, p = 0.00), and correct answers increased from 67.9% to 82.34%. Correct answers regarding risk perception were significantly different between pre-test (54.4%) and post-test (66.6%) (χ² = 73.2, p = 0.00). When coming into contact with patient body fluids and blood only 24.0% of subjects used gloves regularly. The pre

The International AIDS Society convened the multi-stakeholder "Towards an HIV Cure" symposium in Kuala Lumpur, Malaysia in 2013 to address the significant research challenges posed by the search for a cure for HIV infection. Current antiretroviral regimens select for a small reservoir of cells that harbour latent HIV provirus, produce few or no HIV virions, and resist detection or clearance by host immunity. The symposium examined basic molecular science and animal model data, and emerging and ongoing clinical trial results to prioritise strategies and determine the viral and immune responses that could lead to HIV remission without ART. Here we review the presentations that scrutinized the molecular mechanisms controlling virus expression from proviral DNA, and the intrinsic cellular restriction and immune mechanisms preventing viral production. Insights from the basic science have translated into new therapeutic strategies seeking HIV remission without ongoing therapy, and much interest was focused on these ongoing trials. We also summarise the emerging ethical issues and patient expectations as concepts move into the clinic.

Improvement in treatment has led to decreased death in youth with human immunodeficiency virus (HIV) in developed countries. Despite this, youth with HIV are still at risk for increased mortality and morbidity compared with their uninfected counterparts. In developing countries, high numbers of youth die from acquired immune deficiency syndrome (AIDS)-related illnesses due to lack of access to consistent antiretroviral treatment. As a result, pediatric palliative care is a relevant topic for those providing care to youth with HIV. A systematic review was conducted to gather information regarding the status of the literature related to pediatric palliative care and medical decision-making for youth with HIV. The relevant literature published between January 2002 and June 2012 was identified through searches conducted using PubMed, CINAHL, Scopus, and PSYCInfo databases and a series of key words. Articles were reviewed by thematic analysis using the pillars of palliative care set out by the National Consensus Project. Twenty-one articles were retained after review and are summarized by theme. In general, few empirically based studies evaluating palliative care and medical decision-making in youth with HIV were identified. Articles identified focused primarily on physical aspects of care, with less attention paid to psychological, social, ethical, and cultural aspects of care. We recommend that future research focuses on broadening the evaluation of pediatric palliative care among youth with HIV by directly evaluating the psychological, social, ethical, and cultural aspects of care and investigating the needs of all involved stakeholders.

HIV/AIDS fatalism may impact on individuals' health-seeking behaviour and HIV-prevention efforts. This descriptive study measured levels of HIV/AIDS fatalism and documented HIV/AIDS beliefs and practices among a sample of Gabonese and Malians living in Gabon, West Africa. The Powe Fatalism Inventory-HIV/AIDS version was used to measure levels of fatalism, while a short-answer survey was used to document personal beliefs and behaviours related to HIV and AIDS among 160 people in Gabon. The mean score of HIV/AIDS fatalism for the total sample was 6.8 on a 15-point scale. Malians had a more fatalistic outlook than Gabonese (mean scores 9.4 versus 5.3), Muslims were more fatalistic than persons of other religions (mean scores 9.2 versus 5.3), while healthcare providers were less fatalistic than non-providers (mean scores 3.8 versus 7.4). People that did not believe that HIV/AIDS is a punishment from God had a lower mean score of fatalism than those who did. Most of the sample believed that AIDS is a real disease, and most did not think that only immoral people discuss HIV and AIDS. The HIV-prevention indicators that related to lower scores of fatalism included knowing HIV-positive people, having had more years of formal education, a willingness to disclose one's HIV status (if known), and experience of HIV/AIDS education. Respondents who had tested for HIV were no less fatalistic than those who had never tested. The findings provide data from a part of the world where HIV/AIDS beliefs have rarely been documented. The results indicate a need for additional studies on correlations between HIV/ AIDS fatalism, HIV-prevention behaviours, and religious belief systems.

Many outstanding discoveries accompany the existence of HIV infections. International teams of scientists cooperate and in their work they use a great many methods from haematology and immunology to methods of molecular biology that pass into methods of molecular virology. These, in turn, open new prospects for methods of molecular epidemiology. The development of sensitive and specific antibody tests made possible the testing of blood intended for transfusions and helped map the epidemilogical situation, describe the clinical course of the disease and, in particular, diagnose the asymptomaic stage of infection. Gradually, the jigsaw puzzle of the pathogenesis of HIV infections was completed. The tremendous advances in antiretrovirus treament meant a turning point in the mortality and morbidity of HIV infection. Clinical trials of therapeutic vaccines are in progress. Yet despite all the advances and prevention efforts the HIV/AIDS pandemic continues.

The objective of this study was to analyze the scientific production on health interventions related to hygiene for adults with HIV/AIDS. An integrative literature review was performed using six databases in June 2013. The descriptors AIDS and Hygiene were used, in Portuguese, English or Spanish. A total of 682 articles were found and 16 were selected. Personal hygiene practices were identified, such as hand washing, showers, tooth brushing and quitting smoking. Food hygiene practices involved washing food and kitchen utensils, using treated water, conserving and cooking food. Environmental hygiene took into account raising domestic animals, control of disease vectors, household cleanliness, waste disposal and basic sanitation. In conclusion, these specific hygiene interventions can be applied to the general population and, especially, to people with HIV/AIDS, due to immunosuppression.

This study explores HIV/AIDS communication strategies among church leaders at predominately African American churches in a metropolitan city and surrounding areas in North Carolina. The church leaders contacted for the study are members of an interfaith-based HIV/AIDS program. The researchers used semi-standardized interviews to explore how church leaders address HIV/AIDS in the church. The findings indicate that the seven church leaders who participated in the study use a variety of communication channels to disseminate HIV/AIDS information for congregants and their surrounding communities, which include both interpersonal and mass media.

Based on findings demonstrating the simian ancestry of HIV, AIDS has been reported to be a zoonosis. However, this theory has never been proved and must seriously be questioned. Several arguments show that HIV-AIDS is not a zoonosis. (i) If AIDS were a zoonosis, there must be evidence of AIDS being directly acquired from an animal species, as is rabies, a disease that is directly acquired from animals. (ii) Despite long-term and frequent human exposure to SIV-infected monkeys in Africa, only 11 cross-species transmission events are known, and only four of these have resulted in significant human-to-human transmission, generating HIV-1 groups M and O and HIV-2 groups A and B. The closest relatives of SIVcpz (HIV-1 group N) and of SIVsm (HIV-2 groups C-H) are extremely rare, with only six HIV-1 group N-infected patients and only single individuals known to be infected by HIV-2 groups C-H. SIV, while capable of cross-species transmission, is thus poorly adapted for disease and epidemic spread. If AIDS were a zoonosis that is capable of significant human-to-human spread, there would be a plethora of founder subtypes and groups. (iii) Human exposure to SIV is thousands of years old, but AIDS emerged only in the 20th century. If AIDS were a zoonosis that spread into the human population, it would have spread to the West during slave trade. (iv) Experimental transmission of SIVs to different species of monkeys is often well controlled by the new host, showing that the virus and not the disease is transmitted. Therefore, we conclude that cross-species transmission of SIV does not in itself constitute the basis for a zoonosis. Transmission per se is not the major requirement for the generation of the AIDS epidemic. All HIVs do derive from simian species, but AIDS does not qualify as a zoonosis and this explanation cannot in itself account for the origin of AIDS epidemic. It is important to distinguish AIDS from true zoonoses (e.g. rabies) because research is needed to

HIV-2 has a lower pathogenicity and transmission rate than HIV-1. Neutralizing antibodies could be contributing to these observations. Here we explored side by side the potency and breadth of intratype and intertype neutralizing activity (NAc) in plasma of 20 HIV-1-, 20 HIV-2-, and 11 dually HIV-1/2 (HIV-D)-seropositive individuals from Guinea-Bissau, West Africa. Panels of primary isolates, five HIV-1 and five HIV-2 isolates, were tested in a plaque reduction assay using U87.CD4-CCR5 cells as targets. Intratype NAc in HIV-2 plasma was found to be considerably more potent and also broader than intratype NAc in HIV-1 plasma. This indicates that HIV-2-infected individuals display potent type-specific neutralizing antibodies, whereas such strong type-specific antibodies are absent in HIV-1 infection. Furthermore, the potency of intratype NAc was positively associated with the viral load of HIV-1 but not HIV-2, suggesting that NAc in HIV-1 infection is more antigen stimulation dependent than in HIV-2 infection, where plasma viral loads typically are at least 10-fold lower than in HIV-1 infection. Intertype NAc of both HIV-1 and HIV-2 infections was, instead, of low potency. HIV-D subjects had NAc to HIV-2 with similar high potency as singly HIV-2-infected individuals, whereas neutralization of HIV-1 remained poor, indicating that the difference in NAc between HIV-1 and HIV-2 infections depends on the virus itself. We suggest that immunogenicity and/or antigenicity, meaning the neutralization phenotype, of HIV-2 is distinct from that of HIV-1 and that HIV-2 may display structures that favor triggering of potent neutralizing antibody responses.

Angola, located in South-Western Africa, has a remarkably low HIV/AIDS prevalence in the adult population (3.7%). It is bordered in the North by the Democratic Republic of Congo (DRC) and Republic of Congo that are at the origin of human HIV-1 infections. It is, therefore, likely that HIV-1 strains circulating in Angola are genetically diverse and representative of the origin of the HIV/AIDS epidemic. The aim of this work was to investigate in detail the genetic diversity and molecular epidemiology of HIV-1 in Angola. Almost 400 sequences were obtained from the gag (p17), pol (PR and RT) and/or env (C2C3) genes of 159 HIV-1 infected patients living in eight provinces of Angola (Benguela, Cabinda, Cuanza Norte, Luanda, Lunda Norte, Malange, Uíge, and Zaire) and their genotype was determined by phylogenetic analyses. Gene regions representing all HIV-1 group M clades were found as well as unclassifiable sequences. In env and pol (RT), two groups of sequences forming distinct sub-clusters within the subtype A radiation were found and may define new A5 and A6 sub-subtypes. Recombinant forms were found in almost half (47.1%) of the patients of which 36.0% were second-generation recombinants. Fifty-eight different patterns of recombination were found. The A subtype, including CRF02_AG, was represented in most recombinant viruses. Epidemiological data suggests that the AIDS epidemic in Angola has probably started as early as 1961, the major cause being the independence war, and spread to Portugal soon thereafter. The extraordinary degree of HIV-1 group M genetic diversity and evolution in Angola may pose unprecedented challenges to diagnostic, treatment and prevention of HIV-1 infection.

A stochastic spatial model based on the Monte Carlo approach is developed to study the dynamics of human immunodeficiency virus (HIV) infection. We aim to propose a more detailed and realistic simulation frame by incorporating many important features of HIV dynamics, which include infections, replications and mutations of viruses, antigen recognitions, activations and proliferations of lymphocytes, and diffusions, encounters and interactions of virions and lymphocytes. Our model successfully reproduces the three-phase pattern observed in HIV infection, and the simulation results for the time distribution from infection to AIDS onset are also in good agreement with the clinical data. The interactions of viruses and the immune system in all the three phases are investigated. We assess the relative importance of various immune system components in the acute phase. The dynamics of how the two important factors, namely the viral diversity and the asymmetric battle between HIV and the immune system, result in AIDS are investigated in detail with the model.

The escalating HIV/AIDS epidemic worldwide demands that on-going prevention efforts be strengthened, disseminated, and scaled-up. System-level interventions refer to programs aiming to improve the functioning of an agency as well as the delivery of its services to the community. System-level interventions are a promising approach to HIV/AIDS prevention because they focus on (a) improving the agency’s ability to adopt evidence-based HIV prevention and care programs; (b) develop and establish policies and procedures that maximize the sustainability of on-going prevention and care efforts; and (c) improve decision-making processes such as incorporating the needs of communities into their tailored services. We reviewed studies focusing on system-level interventions by searching multiple electronic abstracting indices, including PsycInfo, PubMed, and ProQuest. Twenty-three studies out of 624 peer-reviewed studies (published from January 1985 to February 2007) met study criteria. Most of the studies focused on strengthening agency infrastructure, while other studies included collaborative partnerships and technical assistance programs. Our findings suggest that system-level interventions are promising in strengthening HIV/AIDS prevention and treatment efforts. Based on our findings, we propose recommendations for future work in developing and evaluating system-level interventions. PMID:18369722
As persons living with HIV/AIDS live longer, both the prevalence and incidence of HIV infection in older women is expected to increase, and this review presents a model and review of the extant literature on older women with HIV/AIDS in the United States. Older women are rarely addressed in the discourse about HIV risk and prevention, and their concerns are often missed by risk reduction programs that typically target men and younger adults. Societal biases around aging can compound factors such as stigma and disclosure for older women. Primary care providers are often not recommending routine HIV testing to older women, or addressing the impact of age related physiological changes on risk and sexual health. Many older women may be starting new relationships and the role of relational variables that are specific to this group of women are key in understanding prevention and treatment. Empirical research focused on the needs of older women, and recognition of the diverse composition and needs of this group is needed to inform prevention, intervention and best practices with this population of women.

The multiple therapeutic approaches developed so far to cope HIV-1 infection, such as anti-retroviral drugs, germicides and several attempts of therapeutic vaccination have provided significant amelioration in terms of life-quality and survival rate of AIDS patients. Nevertheless, no approach has demonstrated efficacy in eradicating this lethal, if untreated, infection. The curative power of gene therapy has been proven for the treatment of monogenic immunodeficiensies, where permanent gene modification of host cells is sufficient to correct the defect for life-time. No doubt, a similar concept is not applicable for gene therapy of infectious immunodeficiensies as AIDS, where there is not a single gene to be corrected; rather engineered cells must gain immunotherapeutic or antiviral features to grant either short- or long-term efficacy mostly by acquisition of antiviral genes or payloads. Anti-HIV/AIDS gene therapy is one of the most promising strategy, although challenging, to eradicate HIV-1 infection. In fact, genetic modification of hematopoietic stem cells with one or multiple therapeutic genes is expected to originate blood cell progenies resistant to viral infection and thereby able to prevail on infected unprotected cells. Ultimately, protected cells will re-establish a functional immune system able to control HIV-1 replication. More than hundred gene therapy clinical trials against AIDS employing different viral vectors and transgenes have been approved or are currently ongoing worldwide. This review will overview anti-HIV-1 infection gene therapy field evaluating strength and weakness of the transgenes and payloads used in the past and of those potentially exploitable in the future.

The Human Immunodeficiency Virus (HIV) is an infectious agent that attacks the immune system cells. Without a strong immune system, the body becomes very susceptible to serious life threatening opportunistic diseases. In spite of the great progresses on medication and prevention over the last years, HIV infection continues to be a major global public health issue, having claimed more than 36 million lives over the last 35 years since the recognition of the disease. Monitoring, through registries, of HIV-AIDS cases is vital to assess general health care needs and to support long-term health-policy control planning. Surveillance systems are therefore established in almost all developed countries. Typically, this is a complex system depending on several stakeholders, such as health care providers, the general population and laboratories, which challenges an efficient and effective reporting of diagnosed cases. One issue that often arises is the administrative delay in reports of diagnosed cases. This paper aims to identify the main factors influencing reporting delays of HIV-AIDS cases within the portuguese surveillance system. The used methodologies included multilayer artificial neural networks (MLP), naive bayesian classifiers (NB), support vector machines (SVM) and the k-nearest neighbor algorithm (KNN). The highest classification accuracy, precision and recall were obtained for MLP and the results suggested homogeneous administrative and clinical practices within the reporting process. Guidelines for reductions of the delays should therefore be developed nationwise and transversally to all stakeholders.

Jamaica has a well-established, comprehensive National Human Immunodeficiency Virus (HIV) programme that has slowed the HIV epidemic and mitigated its impact. Adult HIV prevalence has been stable at approximately 1.5% since 1996. HIV rates are high among those most at risk such as sex-workers (9%) and men who have sex with men [MSM] (31.8%). Risk behaviour among adults with AIDS includes multiple sexual partners (80%), a history of a sexually transmitted infection [STI] (51.1%), commercial sex (23.9%) and crack/cocaine (8.0%). Approximately 20% of all reported AIDS cases, mainly women, give no history of any of the usual risk factors for HIV infection. The national programme is based in the Ministry of Health. Since 1988, Jamaica has had a national plan to guide its HIV response. A National AIDS Committee was established in 1988 to lead the multi-sectoral response. Prevention approaches have included information, education and communication campaigns, condom promotion, sexually transmitted infections (STI) control, targeted interventions, cultural approaches, outreach and peer education, workplace programmes and HIV counselling and testing. Concerted efforts have been made to reduce HIV stigma and discrimination. Antiretroviral therapy (ARV) was introduced for prevention of mother-to-child transmission in 2001 and a public access treatment programme introduced in 2004. A national HIV/AIDS Policy was adopted unanimously in parliament in 2005. The National Strategic plan 2007-2012 commits Jamaica to achieving universal access to HIVprevention, treatment and care. Awareness of HIV and how to prevent it is near universal though belief in myths remains strong. The condom market has increased from approximately 2.5 million in 1985 to 12 million in 2006 while condom use has grown significantly with nearly 75% of men and 65% of women reporting condom use at last sex with a non-regular partner The proportion of women 15-24 years reporting ever having a HIV test increased

The objective of this cross-sectional study was to assess the nutritional status of children and adolescents with human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) receiving highly active antiretroviral therapy (HAART). One hundred and eighteen subjects aged 6-19 years attending an outpatient clinic in São Paulo city were involved in the study. The following anthropometric measurements were assessed: weight, height, waist circumference and triceps and subscapular skinfold thickness. One (0.9%) adolescent was diagnosed with abdominal obesity based on waist circumference measurement; three (2.5%) adolescents were obese based on subscapular skinfold thickness. According to the body mass index, the population studied was mainly eutrophic. The prevalence of fat redistribution, a characteristic of patients with HIV/AIDS under HAART, was low. We advise the development of further studies to assess the nutritional status of children and adolescents with HIV/AIDS using anthropometric measurements as well as computed tomography to detect fat redistribution.

HIV/AIDS patients face unique oral diagnostic and treatment challenges. The aim of this investigation among dental school deans (DSD) and graduate school applicants (GSA) who had qualified from 30 different dental schools was to assess their perceptions on dental education relevant to infection control (IC) and HIV/AIDS patient care. The questionnaire included Likert-type scale evaluations of agreement with statements. Of 158 questionnaires, 23 DSD (68% response rate), and 123 GSA (100% response rate) returned valid questionnaires. Fifteen (65%) DSD and 89 (72%) GSA ranked as "very strong" their perception that infection control prevents the transmission of blood borne viruses. However, the perception prevailed, among DSD and GSA, that HIV infection was a "very strong" to "strong" occupational hazard. Special reprocessing of instruments used on HIV patients was frequently reported. Many considered "very strong" to "strong" that HIV/AIDS patients must be treated in specialized clinics, and nearly half (48%) of the DSD and one third (35%) of the GSA stated that their school does refer HIV/AIDS patients to dental treatment in specialized clinics. These results indicate that many dental schools in Mexico must provide better education on IC and HIV/AIDS patient care to enhance attitudes toward HIV/AIDS patients.
The public sector supports most HIV/AIDS prevention and care activities in developing countries, with significant funding provided by the US Agency for International Development, the Overseas Development Authority, the European Community, and international banking institutions such as the World Bank. Local nongovernmental organizations (NGOs) and international private voluntary organizations (PVOs) implement many of the grassroots prevention and care efforts in developing countries, but often require support from donor agencies. While the private commercial sector has played a minor role in supporting HIV/AIDS prevention and care efforts, a number of local and multinational companies are beginning to recognize the importance of protecting their workers from HIV infection. These companies are motivated by a sense of moral obligation and/or view HIV/AIDS prevention as a cost-effective investment. Mainly affecting the most economically productive age groups, the HIV/AIDS epidemic will have a significant impact upon private industry. Workplace-based prevention programs and policies, private sector resources for HIV/AIDS prevention and care, how HIV/AIDS programs can benefit from the private sector's experience in commercial service delivery, research and development, and corporate direct cash and in-kind contributions to government and NGO HIV/AIDS prevention activities are discussed. The AIDS Control and Prevention (AIDSCAP) Project's Businesses Managing AIDS Project helps owners and managers understand the potential impact of HIV/AIDS upon their businesses and the benefits of HIV/AIDS prevention.

Within sub-Saharan Africa, women are disproportionately at risk for acquiring and having human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). It is important to clarify whether gender inequalities in HIV prevalence in this region are explained by differences in the distributions of HIV risk factors, differences in the effects of these risk factors or some combination of both. We used an extension of the Blinder–Oaxaca decomposition approach to explain gender inequalities in HIV/AIDS in Kenya, Lesotho and Tanzania using data from the demographic and health and AIDS indicator surveys. After adjusting for covariates using Poisson regression models, female gender was associated with a higher prevalence of HIV/AIDS in Kenya [prevalence ratio (PR) = 1.73, 95% confidence interval (CI) = 1.33, 2.23 in 2003] and Lesotho (PR = 1.39, 95% CI = 1.20, 1.62 in 2004/05), but not in Tanzania. Decomposition analyses demonstrated two distinct patterns over time. In Tanzania, the gender inequality in HIV/AIDS was explained by differences in the distributions of HIV risk factors between men and women. In contrast, in Kenya and Lesotho, this inequality was partly explained by differences in the effects across men and women of measured HIV/AIDS risk factors, including socio-demographic characteristics (age and marital status) and sexual behaviours (age at first sex); these results imply that gender inequalities in HIV/AIDS would persist in Kenya and Lesotho even if men and women had similar distributions of HIV risk factors. The production of gender inequalities may vary across countries, with inequalities attributable to the unequal distribution of risk factors among men and women in some countries and the differential effect of these factors between groups in others. These different patterns have important implications for policies to reduce gender inequalities in HIV/AIDS. PMID:24345343

Abstract Despite the Mozambique government's efforts to curb human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS), national prevalence is 11.5% and support is needed to expand HIV-related services and improve program quality. Positive prevention (PP) programs, which prioritize HIV prevention with people living with HIV and AIDS (PLHIV), have been recognized as an important intervention for preventing new HIV infections. To address this, an evidence-based PP training intervention was implemented with HIV healthcare providers in Mozambique. This study focuses on the acceptability and feasibility of a PP intervention in HIV clinics from the healthcare provider perspective. In-depth interviews were conducted with 31 healthcare providers from three provinces who participated in PP trainings in Mozambique. Interview data were coded using content analysis. Study data suggest that healthcare providers found PP acceptable, feasible to implement in their HIV work in clinic settings, and valued this strategy to improve HIV prevention. The PP training also led providers to feel more comfortable counseling their patients about prevention, with a more holistic approach that included HIV testing, treatment and encouraging PLHIV to live positively. While overall acceptance of the PP training was positive, several barriers to feasibility surfaced in the data. Patient-level barriers included resistance to disclosing HIV status due to fear of stigma and discrimination, difficulty negotiating for condom use, difficulty engaging men in testing and treatment, and the effects of poverty on accessing care. Providers also identified work environment barriers including high patient load, time constraints, and frequent staff turnover. Recognizing PP as an important intervention, healthcare providers should be trained to provide comprehensive prevention, care and treatment for PLHIV. Further work is needed to explore the complex social dynamics and cultural challenges
The aim of this paper is to present the most relevant musculoskeletal disorders, their diagnosis and treatment to the scientific community and the professionals in charge of patients with human immunodeficiency virus (HIV) infection. These recommendations have been agreed by a panel of experts from the National AIDS Plan (PNS) and the AIDS Study Group (GESIDA). The group have reviewed the efficacy and safety results of clinical trials, cohort studies and pharmacokinetic studies published in biomedical journals (PubMed and Embase), or presented at conferences. Three levels of evidence have been defined according to the sources of data: level A, randomized controlled trials; level B, cohort or case-control; and level C, descriptive studies and expert opinion. Based on this evidence, the authors have decided to recommend, consider or not recommend for each situation. The decrease in bone mineral density is common in HIV-infected patients on antiretroviral treatment, especially during the first year (from 2 to 4%), with a subsequent partial recovery. A dual energy x-ray absorptiometry (DEXA) scan is recommended in patients over 50 years old with HIV infection, history of bone fractures and/or risk factors. Treatment with bisphosphonates has been shown to be effective. Osteoarticular infections are more frequent than in the non-infected population. The level of immunosuppression, risk practice, and antiretroviral treatment should be considered for a proper diagnosis and therapeutic approach. Laboratory and imaging procedures recommended for the study of musculoskeletal processes in HIV infected subjects are the same as in the general population. Osteonecrosis and decreased bone mineral density are the most frequent alterations in children. An early diagnosis of bone disorders is needed. The influence of modifiable risk factors must be avoided and initiate treatment when necessary. Bisphosphonates have been effective in osteoporosis.

Background: One of the reported obstacles to the achievement of universal access to Human Immunodeficiency Virus (HIV) prevention, treatment, care, and support programs includes stigma and discrimination from health workers, particularly nurses. Since nursing students would become future practising nurses and are most likely exposed to caring for people living with HIV/AIDS (PL WHA) during their training, it is of great importance to assess the knowledge, attitude, and practice of student nurses toward the reduction of HIV/AIDS-related stigma and discrimination. Materials and Methods: A descriptive survey research design was used. A total of 150 nursing students were selected using the simple random sampling technique of fish bowl method with replacement. Data were obtained using a self-administered (33-item) validated questionnaire to assess the knowledge, attitude, and practice of student nurses with regard to HIV/AIDS-related stigma and discrimination reduction strategies. Reliability of the tool was tested using Cronbach alpha (R) yielding a reliability value of 0.72. Data collected were analyzed with descriptive statistics of frequencies and percentages. Results: Majority (76.0%) of the respondents were females and 82.7% were married. Respondents were found to have high knowledge (94.0%) of strategies for reducing HIV/AIDS-related stigma and discrimination. Also, 64% had moderate discriminatory attitude, 74% engaged in low discriminatory practice, while 26% engaged in high discriminatory practice. Conclusions: Student nurses had adequate knowledge about strategies for reducing HIV/AIDS-related stigma and discrimination; negative discriminatory attitude toward PLWHA and some form of discriminatory practices exist in participants’ training schools. It is, therefore, recommended that an educational package on reduction of HIV/AIDS-related stigma and discrimination be developed and implemented for the participants. PMID:26793257

African American female inmates are disproportionately affected by the human immunodeficiency virus (HIV), the virus that causes acquired immune deficiency syndrome (AIDS), with heterosexual contact as the primary mode of transmission. This could be the result of racial differences in the strategies used by women to persuade a potential sexual partner to discuss AIDS and engage in condom use. Data were collected from 336 female inmates in three correctional institutions as part of the Reducing Risky Relationships for HIV (RRR-HIV) protocol within the Criminal Justice Drug Abuse Treatment Studies (CJ-DATS) cooperative agreement. Bivariate analyses indicated that African American drug using women were more likely than Whites to use the rational, withdrawal, and persistence approaches to discuss AIDS with an intimate sexual partner. Negative binomial regression models were used to identify which interpersonal discussion strategies were significant correlates of the number of the times White participants and African American participants had unprotected vaginal sex in the 30 days prior to incarceration. Results from the multivariate model indicate that White women who are more likely to use the rational discussion strategy were 15% less likely to engage in vaginal sex without a condom; however, these findings were not replicated in the African American sample. Findings add to the literature on racial differences in HIV/AIDS discussion strategies and sexual risk behaviors among drug abusing female criminal offenders. PMID:19283952

HIV/AIDS stigma continues to be a challenge for HIV prevention and treatment. When health professionals manifest stigma it can limit access to quality treatment. With an ever-growing epidemic among Latinos, including Puerto Ricans living on the Caribbean Island, the social and structural factors that foster HIV/AIDS stigma need to be understood. In this study, we documented the association of religion with HIV/AIDS stigma in a sample of medical students in Puerto Rico. Findings suggest that importance placed on religion, and participation in religious activities, is associated with HIV/AIDS stigma for this population. PMID:23442492

The AIDS Cancer and Specimen Resource (ACSR) supports scientific discovery in the area of HIV/AIDS-associated malignancies. The ACSR was established as a cooperative agreement between the NCI (Office of the Director, Division of Cancer Treatment and Diagnosis) and regional consortia, University of California, San Francisco (West Coast), George Washington University (East Coast) and Ohio State University (Mid-Region) to collect, preserve and disperse HIV-related tissues and biologic fluids and controls along with clinical data to qualified investigators. The available biological samples with clinical data and the application process are described on the ACSR web site. The ACSR tissue bank has more than 100,000 human HIV positive specimens that represent different processing (43), specimen (15), and anatomical site (50) types. The ACSR provides special biospecimen collections and prepares speciality items, e.g., tissue microarrays (TMA), DNA libraries. Requests have been greatest for Kaposi's sarcoma (32%) and non-Hodgkin's lymphoma (26%). Dispersed requests include 83% tissue (frozen and paraffin embedded), 18% plasma/serum and 9% other. ACSR also provides tissue microarrays of, e.g., Kaposi's sarcoma and non-Hodgkin's lymphoma, for biomarker assays and has developed collaborations with other groups that provide access to additional AIDS-related malignancy specimens.

In Chile, the first cases of AIDS were reported 23 years ago, and since then, through December 2006, 17.235 persons have been notified with HIV infection or AIDS1. To the year 2005, there have been 5.288 fatal cases of AIDS. The last available data indicates that notification rates for AIDS and HIV infection in 2006 were 2.5 and 4.5 per 100.000 inhabitants, respectively, and mortality rate for AIDS in 2005 was 2.4 per 100.000 inhabitants. Trend analysis shows a decline in the notification rate among men, both for HIV infection and AIDS, which could be a real decrease or a sub notification bias. In Chile, like in other countries of the region, variations in the epidemiologic pattern were observed considering age group, gender, educational level and geographic distribution of the population. Currently, the Chilean Ministry of Health has implemented both a surveillance and monitoring system on line, in order to improve the quality and opportunity of the information, therefore providing an important tool to HIV infection/AIDS prevention and control strategies.

HIV/AIDS stigma is a common thread in the narratives of pregnant women affected by HIV/AIDS globally and may be associated with refusal of HIV testing. We conducted a cross-sectional study of women attending antenatal clinics in Kenya (N = 1525). Women completed an interview with measures of HIV/AIDS stigma and subsequently information on their acceptance of HIV testing was obtained from medical records. Associations of stigma measures with HIV testing refusal were examined using multivariate logistic regression. Rates of anticipated HIV/AIDS stigma were high-32% anticipated break-up of their relationship, and 45% anticipated losing their friends. Women who anticipated male partner stigma were more than twice as likely to refuse HIV testing, after adjusting for other individual-level predictors (OR = 2.10, 95% CI: 1.15-3.85). This study demonstrated quantitatively that anticipations of HIV/AIDS stigma can be barriers to acceptance of HIV testing by pregnant women and highlights the need to develop interventions that address pregnant women's fears of HIV/AIDS stigma and violence from male partners.

The objective of this study is to investigate the access to antiretroviral treatment among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in Chiang Mai province, Thailand. Access to antiretroviral treatment is defined in terms of availability, affordability, and acceptability. The data for the study were collected during the period of April 1, 2012–May 31, 2012 from a sample of 380 HIV/AIDS patients in eight hospitals who had received antiretroviral treatment for more than 6 months at the time of data collection. The results of the study show that for most patients, the average traveling time to access health care was acceptable, but the nearly half day waiting time caused them to be absent from their work. In particular, it took longer for patients in the rural and lower income groups to access the treatment than the other groups. Their travel times and food costs relating to the treatment were found to be relatively high and therefore these patients had a higher tendency to borrow or seek financial assistance from their relatives. However, due to improvements in the access to treatment, most patients were satisfied with the services they received. The results imply that policy should be implemented to raise the potential of subdistrict hospitals where access to antiretroviral treatment is available, with participating HIV/AIDS patients acting as volunteers in providing services and other forms of health promotion to new patients. Privacy issues could be reduced if the antiretroviral treatment was isolated from other health services. Additionally, efforts to educate HIV/AIDS patients and society at large should be made.

OBJECTIVE To evaluate the level of HIV/AIDS knowledge among men who have sex with men in Brazil using the latent trait model estimated by Item Response Theory. METHODS Multicenter, cross-sectional study, carried out in ten Brazilian cities between 2008 and 2009. Adult men who have sex with men were recruited (n = 3,746) through Respondent Driven Sampling. HIV/AIDS knowledge was ascertained through ten statements by face-to-face interview and latent scores were obtained through two-parameter logistic modeling (difficulty and discrimination) using Item Response Theory. Differential item functioning was used to examine each item characteristic curve by age and schooling. RESULTS Overall, the HIV/AIDS knowledge scores using Item Response Theory did not exceed 6.0 (scale 0-10), with mean and median values of 5.0 (SD = 0.9) and 5.3, respectively, with 40.7% of the sample with knowledge levels below the average. Some beliefs still exist in this population regarding the transmission of the virus by insect bites, by using public restrooms, and by sharing utensils during meals. With regard to the difficulty and discrimination parameters, eight items were located below the mean of the scale and were considered very easy, and four items presented very low discrimination parameter (< 0.34). The absence of difficult items contributed to the inaccuracy of the measurement of knowledge among those with median level and above. CONCLUSIONS Item Response Theory analysis, which focuses on the individual properties of each item, allows measures to be obtained that do not vary or depend on the questionnaire, which provides better ascertainment and accuracy of knowledge scores. Valid and reliable scales are essential for monitoring HIV/AIDS knowledge among the men who have sex with men population over time and in different geographic regions, and this psychometric model brings this advantage.

From 1984, when the first case of AIDS was diagnosed in Chile, to December 2003, 6.060 patients with AIDS and 6.514 with asymptomatic HIV infection have been notified to a passive national surveillance system; around 3,800 have died due to the infection. Magnitude of the under reporting is discussed. Assumed routes of the infection have been: sexual (94.1%), blood--largely intravenous drug use--(4.3%) and vertical transmission (1.6%). According to analysis performed by the National Commission on AIDS (CONASIDA), a governmental office, HIV/AIDS epidemic in Chile is characterized by: predominance in male homo/bisexuals, urban and rural distribution, impoverishment of the affected people, diagnosis made mainly during adulthood and a steady trend to affecting more women and heterosexuals at large. Since 2001 there has been a continuous increase in access to standard antiretroviral therapy (HAART) for those cared for by the public health system, reaching free coverage for 100% of this population by 2003, which has determined a significant decrease in the rate AIDS-associated clinical manifestations while reaching an stop of the previously increasing lethality of the infection (from a 15% increase from 1993-1997 to 0.2% from 1998-2003).

Infection with HIV ultimately leads to advanced immunodeficiency resulting in an increased incidence of cancer. For example primary effusion lymphoma (PEL) is an aggressive non-Hodgkin lymphoma with very poor prognosis that typically affects HIV infected individuals in advanced stages of immunodeficiency. Here we report on the dual anti-HIV and anti-PEL effect of targeting a single process common in both diseases. Inhibition of the exportin-1 (XPO1) mediated nuclear transport by clinical stage orally bioavailable small molecule inhibitors (SINE) prevented the nuclear export of the late intron-containing HIV RNA species and consequently potently suppressed viral replication. In contrast, in CRISPR-Cas9 genome edited cells expressing mutant C528S XPO1, viral replication was unaffected upon treatment, clearly demonstrating the anti-XPO1 mechanism of action. At the same time, SINE caused the nuclear accumulation of p53 tumor suppressor protein as well as inhibition of NF-κB activity in PEL cells resulting in cell cycle arrest and effective apoptosis induction. In vivo, oral administration arrested PEL tumor growth in engrafted mice. Our findings provide strong rationale for inhibiting XPO1 as an innovative strategy for the combined anti-retroviral and anti-neoplastic treatment of HIV and PEL and offer perspectives for the treatment of other AIDS-associated cancers and potentially other virus-related malignancies.

Abstract: Background: Infection with human papilloma virus (HPV) is the most common sexually transmitted disease in the world. Among the 630 million new cases of HPV that occur each year, 30 million develop anogenital warts. Although subclinical infection with HPV is the most common cause, genital warts are also associated with immunosuppression caused by HIV. In view of the high prevalence of HPV/HIV co-infection particularly among men who have sex with men, the objectives of this study were to determine the prevalence of anogenital warts in men with HIV/AIDS and to identify associated factors. Methods: A cross-sectional study was conducted on 159 men with HIV/AIDS consecutively selected at a referral service in Botucatu, São Paulo, Brazil, in which the association between sociodemographic, behavioral and clinical variables and the presence of anogenital warts was evaluated. After hierarchical analysis of the data, variables presenting a p value ≤ 0.2 were entered into an unconditional multivariate logistic regression model. Results: Forty-nine (31%) of the HIV-positive patients had anogenital warts. The mean age was 44.6 ± 9.6 years. The main factors associated with the presence of anogenital warts were irregular antiretroviral treatment and genital herpes(HSV). Conclusion: The present study demonstrate that anogenital warts occur in almost one-third of the male population infected with HIV and factors associated with a higher risk of being diagnosed with anogenital warts were irregular cART use and co-infection with HSV, other variables could not be associated.

This qualitative study focuses on culturally embedded beliefs about the teaching and learning of HIV/AIDS topics in the Ivory Coast. We aim to analyze and describe factors influencing the implementation of the HIV/AIDS curricula in Ivorian sixth-grade classrooms. With continuous spreading of AIDS in the Ivory Coast, education about HIV/AIDS has to increase; therefore, an urgent need to document, evaluate, and disseminate Ivorian perspectives on what is understood as valuable HIV/AIDS knowledge to prioritize such content in the curriculum is needed. Multiple qualitative methods were collected: individual interviews with 39 teachers, 63 sixth-grade students, eight school administrators, 20 community elders as well as field notes, and document analysis. By promoting HIV/AIDS curricula that is responsive to and inclusive of youth cultural beliefs and aligning teaching practice to Ivorian youth cultural interests, there is a chance that HIV/AIDS education could lead to safer sexual behaviors among Ivorian youth.

This piece begins with a brief literature review that focuses upon how media attempt to make sense of news events and construct meaning about HIV/AIDS. We then focus specifically on a linguistic process identified in French dailies in articles about the prevalence and incidence of HIV/AIDS, namely, the presence of certain adverbs. The impact of this linguistic process is also investigated in an experimental study. The results indicated that participants who were exposed to a message within which epidemiological data were marked by such adverbs compared to those who processed a message without such an adverbial marking expressed a higher level of perceived risk and declared a stronger intention to use a condom and to practice a screening test. They also judged the epidemiological situation as more serious and were more supportive of a coercive management of the epidemic. These effects also appeared when the message referred to a sexually transmitted infection with which the subjects were not familiar.
For this contribution to the special issue on "Mapping Queer Bioethics," the author employs an array of public health and popular media texts (especially Jonathan Demme's film Philadelphia) to challenge the construction and reconstruction of HIV-positive bodies as sites of bioethical concern. In outlining notions of "digital restoration," the author argues that there has been of late a remapping of the first decade of the HIV/AIDS pandemic through media projects assembled from archived materials. Accordingly, the author suggests that in the first decades of the 2000s, we have witnessed a media-archaeological turn, whereby old materials have been reassembled for commemorative purposes that oftentimes perform a reshaping of the topography of the first decade of the AIDS pandemic.

The primary purpose of this study was to assess the role, status and scope of workplace HIV/AIDS committees as a means of effective workplace governance of the HIV/AIDS impact, and their role in extending social protective HIV/AIDS-related rights to employees. In-depth qualitative case studies were conducted in five South African small and medium-sized enterprises (SMEs) that were actively implementing HIV/AIDS policies and programmes. Companies commonly implemented HIV/AIDS policies and programmes through a workplace committee dedicated to HIV/AIDS or a generic committee dealing with issues other than HIV/ AIDS. Management, through the human resources department and the occupational health practitioner often drove initial policy formulation, and had virtually sole control of the HIV/AIDS budget. Employee members of committees were mostly volunteers, and were often production or blue collar employees, while there was a notable lack of participation by white-collar employees, line management and trade unions. While the powers of workplace committees were largely consultative, employee committee members often managed in an indirect manner to secure and extend social protective rights on HIV/AIDS to employees, and monitor their effective implementation in practice. In the interim, workplace committees represented one of the best means to facilitate more effective workplace HIV/AIDS governance. However, the increased demands on collective bargaining as a result of an anticipated rises in AIDS-related morbidity and mortality might prove to be beyond the scope of such voluntary committees in the longer term.

Mass media in China play a significant role in the dissemination of HIV/AIDS knowledge to the general public. Previous studies have described how the Chinese mass media portray HIV/AIDS in general, but no study has yet to examine changes in patterns of HIV/AIDS reporting over time. This study aims to describe and examine newspaper coverage of HIV/AIDS in China from 2000 to 2010. A systematic search of the China Core Newspapers Database was conducted to identify HIV/AIDS-focused news articles; we found 3648 articles. Results show that coverage rates of HIV/AIDS in newspapers remained low, with only about three articles published per newspaper per year between 2000 and 2010. The sources focused primarily on prevention methods (23.7%), development of a cure or vaccine (21.2%), and education and awareness (17.2%). The HIV/AIDS-related topic covered in an article varied significantly depending on scope (national vs. local) of the newspaper (χ(2)=130.37, p<0.001) and article type (χ(2)=455.72, p<0.001). Totally, more articles were classified as positive than negative from 2002 to 2010. Findings indicate that the HIV/AIDS news-reporting pattern has shifted in the past decade, with more news stories disclosing information about prevention or treatment. However, coverage of HIV/AIDS remains insufficient. Enhancing collaboration between health educators and media sources can be an important strategy in disseminating HIV/AIDS knowledge.

The aim of this study was to assess the HIV/AIDS-related knowledge among junior high-school students in Shanghai, China, and the factors influencing this knowledge. A cross-sectional study was conducted in 20 middle schools of two districts by a cluster-stratified selection procedure in Shanghai, China. The 2432 sampled students, aged from 11.1 to 16.7 years, completed a self-administered questionnaire of HIV/AIDS prevention. The results showed that the overall correct rate of HIV/AIDS-related knowledge was 62%. Using multivariable logistic regression analysis, we found that the main factors influencing HIV/AIDS-related knowledge among junior high school students were the type of school (odds ratio [OR] = 1.641), age (OR = 1.727), whether the student was a single child in the family (OR = 1.389), whether the student had previous HIV/AIDS-related education experience (OR = 2.003) and whether the student had ever discussed HIV/AIDS with their parents (OR = 1.282). The results indicate that HIV/AIDS-related knowledge among Shanghai junior high school students is not high enough, and more attention needs to be paid to enhance HIV/AIDS-related knowledge, especially among younger students from common type schools without HIV/AIDS-related education experience. We encourage Chinese parents to get involved in their children's HIV/AIDS prevention education.
Despite three decades of public health promotion based on the scientific explanation of HIV/AIDS, alternative explanations of the disease continue to circulate. While these are seen as counter-productive to health education efforts, what is rarely analysed is their plurality and their tenacity. This article analyses the 'AIDS myths' collected by African HIV/AIDS workplace peer educators during an action research project. These beliefs about HIV/AIDS are organised, in this article, around core ideas that form the basis of 'folk' and 'lay theories' of HIV/AIDS. These constitute non-scientific explanations of HIV/AIDS, with folk theories drawing on bodies of knowledge that are independent of HIV/AIDS while lay theories are generated in response to the disease. A categorisation of alternative beliefs about HIV/AIDS is presented which comprises three folk theories - African traditional beliefs, Christian theology, and racial conspiracy - and three lay theories, all focused on avoiding HIV infection. Using this schema, the article describes how the plausibility of these alternative theories of HIV/AIDS lies not in their scientific validity, but in the robustness of the core idea at the heart of each folk or lay theory. Folk and lay theories of HIV/AIDS are also often highly palatable in that they provide hope and comfort in terms of prevention, cure, and the allocation of blame. This study argue that there is coherence and value to these alternative HIV/AIDS beliefs which should not be dismissed as ignorance, idle speculation or simple misunderstandings. A serious engagement with folk and lay theories of HIV/AIDS helps explain the continued circulation of alternative beliefs of HIV/AIDS and the slow uptake of behavioural change messages around the disease.

The meaningful involvement of women living with HIV/AIDS (MIWA) is a key feature of women-centred HIV care, yet little is known about transforming MIWA from principle to practice. Drawing on focus group data from the Canadian HIV Women's Sexual and Reproductive Health Cohort Study (CHIWOS), we explored HIV-positive women's meaningful involvement in the design and delivery of HIV/AIDS services in British Columbia, Canada. In this article, we highlight the benefits and tensions that emerge as women traverse multiple roles as service users and service providers within their care communities, and the impact this has on their access to care and overall health.

Viruses remain a threat to the health of humans worldwide with 33 million infected with AIDS. Viruses are ubiquitous infecting animals, plants, and bacteria. Each virus infects in its own unique manner making the problem seem intractable. However, some general physical steps apply to many viruses and the application of basic physical modeling can potentially have great impact. The aim of this theoretical study is to investigate the stability of the HIV viral capsid (protein shell). The structural shell can be compromised by physical probes such as pulsed laser light. But what are the weakest regions of the capsid so that we can begin to understand vulnerabilities of these deadly materials? The atomic structure of HIV capsids is not precisely known and we begin by describing our work to model the capsid structure. Next we describe a course grained model to investigate protein interactions within the capsid.

The relationship between drug policy and HIV vulnerability is well documented. However, little research examines the links between racial/ethnic HIV disparities via the Drug War, sexual risk, and stigma. The Drug War HIV/AIDS Inequities Model has been developed to address this dearth. This model contends that inequitable policing and sentencing promotes sexual risks, resource deprivation, and ultimately greater HIV risk for African-Americans. The Drug War also socially marginalizes African Americans and compounds stigma for incarcerated and formerly incarcerated persons living with HIV/AIDS. This marginalization has implications for sexual risk-taking, access to health-promoting resources, and continuum of care participation. The Drug War HIV/AIDS Inequities Model may help illuminate mechanisms that promote increased HIV vulnerability as well as inform structural intervention development and targeting to address racial/ethnic disparities.

Globalisation affects all facets of human life, including health and well being. The HIV/AIDS epidemic has highlighted the global nature of human health and welfare and globalisation has given rise to a trend toward finding common solutions to global health challenges. Numerous international funds have been set up in recent times to address global health challenges such as HIV. However, despite increasingly large amounts of funding for health initiatives being made available to poorer regions of the world, HIV infection rates and prevalence continue to increase world wide. As a result, the AIDS epidemic is expanding and intensifying globally. Worst affected are undoubtedly the poorer regions of the world as combinations of poverty, disease, famine, political and economic instability and weak health infrastructure exacerbate the severe and far-reaching impacts of the epidemic. One of the major reasons for the apparent ineffectiveness of global interventions is historical weaknesses in the health systems of underdeveloped countries, which contribute to bottlenecks in the distribution and utilisation of funds. Strengthening these health systems, although a vital component in addressing the global epidemic, must however be accompanied by mitigation of other determinants as well. These are intrinsically complex and include social and environmental factors, sexual behaviour, issues of human rights and biological factors, all of which contribute to HIV transmission, progression and mortality. An equally important factor is ensuring an equitable balance between prevention and treatment programmes in order to holistically address the challenges presented by the epidemic. PMID:16060961
This article discusses the identity of HIV/AIDS caregivers as constructed by a group of HIV/AIDS caregivers at a non-profit organisation in South Africa. During a 12-month period data were collected through interviews with the organisation's staff and volunteers. Using discourse analysis, the study identified a caregiver identity constructed by participants. This caregiving identity acts as a double-edged sword: while the rewards of caregiving act as a buffer against stressful experiences, the prescriptive nature of the caregiver identity is taxing, and may explain burnout among HIV/AIDS caregivers. The study concludes that for support systems for HIV/AIDS caregivers to be effective, the social culture and identity of HIV/AIDS caregivers must be considered.

Three hundred and one sera of HIV/AIDS patients were tested for anti-Toxoplasma IgG antibody by ELISA technique. The seroprevalence of toxoplasmosis was 41.2% (95% CI: 35.5-46.9) in HIV/AIDS patients. The seroprevalence was significantly higher in the Malay (57.9%) than the Chinese (38.7%), followed by the Indian patients (29.6%) (p<0.05). No possible risk factor, such as contact with cats, consumption of uncooked meat, and history of blood transfusions was found to have any significant association with the presence of anti-Toxoplasma antibody in the study sample (p>0.05). Multivariate analysis was employed to find any association between Toxoplasma seroprevalence and a single subject having single or multiple risk factors. It was found that the association was not statistically significant (p>0.05). Among the HIV/AIDS study samples, 124 (41.2%) samples were found to have positive anti-Toxoplasma antibody, the association between the presence of anti-Toxoplasma antibody and CD4 cell count was determined but no statistically significant association was found (p>0.05). During the study period, only one case of active CNS toxoplasmosis was registered and the diagnostic criteria included: clinical presentations, CT scan finding, serological evidence of anti-Toxoplasma IgG antibody, and respose to anti-Toxoplasma therapy.

The study aims to examine the relationship between masculinity, vulnerability and the prevention of HIV/AIDS, based on reports from young men from the so-called urban working classes, taking into account not only the meanings attributed to prevention by these subjects, but also considering the dialectical relationship between the individual and society. The conceptual framework encompasses the three main aspects of hegemonic masculinity, prevention and vulnerability. This involves qualitative research based on the perspective of dialectical hermeneutics that uses the method of interpretation of meanings. The analysis yielded two main results, namely hegemonic masculinity as a vulnerability factor, and myths and prejudices as factors of vulnerability to HIV/AIDS. By way of conclusion, it reinforces the need for discussion of prevention encompassing the need to put on the agenda the construction of the sex/gender system around which to articulate the social meanings of masculinity and femininity that influence the structural plan of affective sexual relations in general and HIV/AIDS in particular.

The countries of Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) are confronted with one of the fastest growing HIV/AIDS epidemics worldwide, largely driven through injecting drug use. This article, based on a review of academic and grey literature, explores how they have responded. We find major similarities and differences across the region. At one extreme is Turkmenistan, which denies that there is any problem, does not offer harm reduction services or HIV/AIDS treatment and does not report any meaningful data to the international community. Uzbekistan is also pretty closed to outside influences, has discontinued its opioid substitution project and shares with Turkmenistan the legal prohibition of male-to-male sex. Kyrgyzstan originally led many progressive approaches in the region and, like neighbouring Tajikistan, has received substantial assistance by international agencies, in particular the Global Fund. Kazakhstan, with a much higher gross domestic product per capita, has taken on the financing of harm reduction activities through its national budget and has liberalised its drug policies. Yet, across the region punitive approaches to injecting drug use and people living with HIV/AIDS persist as do stigma and discrimination, while coverage with harm reduction programmes and treatment services is still low although with substantial variation across countries.

There is no viable substitute for re-energizing, funding and supporting culturally attuned, locally staffed HIV advocacy and prevention programmes, especially in resource poor settings. The evidence that such interventions are effective remains compelling; and although the cost implications are not negligible, the medium to long-term outcomes must be regarded not as complementary, but as integral, to biomedical interventions. The success of the anti-retroviral drugs upscale has enabled a noticeable improvement in AIDS related morbidity and mortality in the recent years; yet the underlying dynamics of the epidemic remains undetermined by the rate at which new infections are taking place in relation to the number of AIDS deaths. While the rate of new HIV infections is stabilising in some of the hardest hit countries, it remains far too high and the future cost of maintaining an ever-expanding pool of people reliant on daily drugs for survival is unsustainable. Countries must exercise caution in continuing to focus on treatment as a ‘quick fix’ to end AIDS as a public health concern. HIV is a socially culturally induced crisis and, as such, a variety of measures are needed simultaneously to appeal to different people, groups and circumstances. PMID:27347272

AIDS education initiatives need to begin early, within the elementary grades, to be effective. We should no longer underestimate the capacity of young children to understand and benefit from this instruction. In addition, we should not overestimate the impact of brief interventions, and should plan for continued AIDS prevention instruction throughout the school years, involving sequential, developmentally appropriate curricula that respond to the preadolescent's and adolescent's changing cognitive capabilities, social skills, and expanding exposure to sexual experiences. We should require that new approaches and methodologies for AIDS prevention education be developed and evaluated rigorously for efficacy with the same fervor required for the development and evaluation of new drugs to combat this illness on the biologic front. New modalities and approaches should be integrated with those that have already been shown to be effective, creating multimodal and comprehensive educational initiatives comparable to the multidrug treatment regimens. We should be skeptical of those who are satisfied with the implementation of one interesting and simplistic slogan for health promotion efforts for children (e.g., "Just say no"). Even if such efforts were effective in the short term, sole reliance on this approach is likely to result in the development of resistance. As the field of AIDS prevention looks for novel approaches and theoretic constructs, it should borrow ideas from other fields of study and foster interdisciplinary collaborations with professionals from complementary fields. In this manner, educational interventions can move beyond the individual context to begin to address the social influences on sexual behaviors. Sexual behavior is interpersonal and occurs in a social context. Programs must therefore address peer and social pressures to engage in sexual activity. Although attempts are being made to address the social network of children through such efforts as

The Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) pandemic has caused far-reaching effects in sub-Saharan Africa. The pandemic has effectively diminished the workforce, increased poverty rates, reduced agricultural productivity, and transformed the structure of many rural households. HIV/AIDS further strains the already fragile relationship between livelihood and the natural and social environments of these regions. Therefore, the objective of this review is to characterize the impact of HIV/AIDS on the environment and the social infrastructure of rural sub-Saharan Africa. There are many aspects of rural life that contribute to disease transmission of HIV/AIDS and that pose unique challenges to the population dynamics in sub-Saharan Africa. Widespread AIDS-related mortality has caused a decrease in population growth for many African countries. In turn, these alterations in population dynamics have resulted in a decrease in the percentage of prime-age working adults, as well as a gender disparity, whereby, females carry a growing burden of household responsibilities. There is a rising proportion of older adults, often females, who assume the role of provider and caretaker for other dependent family members. These changing dynamics have caused many to exploit their natural surroundings, adopting less sustainable land use practices and utilizing protected resources as a primary means of generating revenue.

In more than 20 years of medical practice, a surprising phenomenon has often occurred: some patients with acquired immunodeficiency syndrome (AIDS) decide not to go to the hospital and they do not let others know that they are suffering from the disease unless they believe that they are dieing. Zhang Shan (a pseudonym) is one such patient with human immunodeficiency virus (HIV)/AIDS who was reluctant to receive antiviral therapy as soon as possible, and this paper shares Zhang's story as he related it. Clearly, there are numerous views as to why patients in China behave as Zhang did. Presented here are several reasons, including society, history, morality and ideology, family, and education. Although all of these reasons do play a role, the patient's mindset and behavior is the most significant reason for a patient's reluctance to seek treatment or disclose his/her status. If the individual patient's mindset and behavior are not dealt with effectively, then HIV/AIDS can continue to spread and threaten additional lives and even the fabric of society. This paper analyzes the reasons why patients are hesitant to receive antiviral therapy, but this paper also suggests steps healthcare personnel can take to encourage patients to seek treatment. Such steps can save the lives of current patients with HIV/AIDS. In addition, sound public health measures and a rational approach to treatment are important to helping potential patients with HIV/AIDS.

Homeless gay and bisexual (G/B) young men have multiple risk factors that increase their risk of contracting hepatitis B virus (HBV) and human immunodeficiency virus (HIV). This study used baseline information from structured instruments to assess correlates of knowledge to HIV and HBV infection from 267 young (18-39 year old) G/B active methamphetamine, cocaine, and crack-using homeless men enrolled in a longitudinal trial. The study is designed to reduce drug use and improve knowledge of hepatitis and HIV/AIDS in a community center in Hollywood, California. Regression modeling revealed that previous hepatitis education delivered to G/B men was associated with higher levels of HIV/AIDS and hepatitis knowledge. Moreover, higher HIV/AIDS knowledge was associated with combining sex and drinking alcohol. Associations with hepatitis B knowledge was found among G/B men who were engaging in sex while under the influence of marijuana, who were receiving support from non-drug users, and who had been homeless in the last 4 months. Although being informed about HIV/AIDS and hepatitis did not preclude risky sexual and drug use behavior, knowledge about the dangers of concurrent sex with substance use is important. As higher levels of knowledge of hepatitis was associated with more moderate drug use, early access to testing and teaching harm reduction strategies remain critical to reduce exposure and infection of HBV and HIV in this population.

Despite a number of programmes to prevent HIV among men who have sex with men (MSM) and, more generally, sexually diverse populations, gay and other homosexually active men continue to be at heightened risk of HIV and its consequences. This paper analyses some of the reasons for this situation and offers policy and programmatic recommendations to contribute to a solution. The social exclusion of MSM and transgender individuals is an overwhelming reality in the majority of countries worldwide. Although progress has been achieved in some countries, in most of the world the situation remains problematic. Present challenges to equality and to the realization of health, include the membership of groups or subcultures with high HIV prevalence, lower quality and coverage of services and programmes and the impact of higher-level influences such as laws, public policies, social norms and culture, which together configure an environment that is hostile to the integration and needs of certain groups. A social inclusion perspective on HIV prevention and AIDS-related care implies the adoption of strategies to understand and confront social vulnerability. Sexual exclusion intensifies the burden of HIV transmission and morbidity. As part of a comprehensive response there is an urgent need to: (i) improve our understanding of the characteristics and HIV burden among sexually diverse populations; (ii) creatively confront legal, social and cultural factors enhancing sexual exclusion; (iii) ensure the provision of broad-based and effective HIV prevention; (iv) offer adequate care and treatment; and (v) confront special challenges that characterize work with these populations in lower and middle-income countries.

Objective: The aim of this study was to examine clinico-epidemiological properties of HIV/AIDS patients. Materials and Methods: For this purpose, 115 HIV/AIDS patients monitored in our clinic between January 1, 1998, and December 31, 2013, were retrospectively evaluated. Results: For the 115 patients with a diagnosis of HIV/AIDS that we monitored, the mean age at the time of presentation was 34.5±13.21 (10–79) years. Eighty-nine (76.5%) patients were male and 27 (23.5%), female. In this study, HIV/AIDS was the most prevalent in the young male population with a low educational and sociocultural level. The most common mode of transmission in our patients was heterosexual relations: approximately 1 patient in 3 had a history of traveling to countries with a high prevalence of HIV/AIDS, namely, Russia and Ukraine. The examination of diagnosis with respect to years showed an increase in new cases since 2008. Only 21 (18.3%) of our patients were diagnosed through clinical symptoms, while 91 (81.7%) during routine scanning. At first presentation, 68% of our patients were stage A; 4.7%, stage B; and 27.3%, stage C. The mean length of the monitoring of our patients was 2.74 years (2–180 months). Thirteen (11.3%) patients died due to opportunistic infections and malignities. The most common opportunistic infection was tuberculosis (16.5%), followed by syphilis and HBV. Malignity, most commonly intracranial tumor, was seen in 8.6% patients. Conclusion: The disease was generally seen in the young male population with a low sociocultural level, and it was most frequently transmitted by heterosexual sexual contact. This clearly shows the importance of sufficient, accurate information, and education on the subject of the disease and its prevention. The fact that many of our patients were diagnosed in the late stage due to stigma and that diagnosis was largely made through scanning tests confirms the importance of these tests in early diagnosis.

This paper aims to investigate whether good governance of a recipient country is a necessary condition and what combinations of factors including governance factor are sufficient for low prevalence of HIV/AIDS in HIV/AIDS aid recipient countries during the period of 2002-2010. For this, Fuzzy-set Qualitative Comparative Analysis (QCA) was used. Nine potential attributes for a causal configuration for low HIV/AIDS prevalence were identified through a review of previous studies. For each factor, full membership, full non-membership, and crossover point were specified using both author's knowledge and statistical information of the variables. Calibration and conversion to a fuzzy-set score were conducted using Fs/QCA 2.0 and probabilistic tests for necessary and sufficiency were performed by STATA 11. The result suggested that governance is the necessary condition for low prevalence of HIV/AIDS in a recipient country. From sufficiency test, two pathways were resulted. The low level of governance can lead to low level of HIV/AIDS prevalence when it is combined with other favorable factors, especially, low economic inequality, high economic development and high health expenditure. However, strengthening governance is a more practical measure to keep low prevalence of HIV/AIDS because it is hard to achieve both economic development and economic quality. This study highlights that a comprehensive policy measure is the key for achieving low prevalence of HIV/AIDS in recipient country.
