Abstract
BACKGROUND For many deadly viruses, there are no preventive and / or therapeutic vaccines approved by health authorities World-wide (e.g., HIV, Ebola, Dengue, and many others). Although, for some viruses, prophylactic vaccines are very effective (e.g., HBV, and many others).In this realm, we design, manufacture, test, and streamline into the clinics novel viral universal vaccines (VUV). VUV have such unique features, that medical vaccination or natural infection induced immunity against some viruses (e.g., HBV) upon the VUV's administration to the infected with other, different viruses patients, is redirected against these other, newly infecting viruses (e.g., HIV). SPECIFIC AIM The specific aim of this work was biomolecular engineering of the HIV universal vaccine comprising the two main functional domains: CD4 or anti-gp120 - as the HIV tagging domain and HBsAg - as the immune response eliciting domain, so that upon its administration the HBV medical immunization or natural infection induced immunity would be redirected, accelerated, and amplified to fight the HIV infection. HEALTHY DONORS AND PATIENTS Per the Institutional Review Board approval and in compliance with the Declaration of Helsinki, all healthy donors and patients were presented with the Patients' Bill of Rights and provided Patient Informed Consent. All the procedures were pursued by the licensed medical doctors. METHODS & RESULTS We have biomolecularly engineered HIV universal vaccine (HIVUV) comprising human CD4 or anti-gp120 and HBsAg of HBV. By immunoblotting and magnetic activated molecular sorting, we have demonstrated high specificity of this vaccine in binding HIV. By flow cytometry and nuclear magnetic resonance, we have demonstrated high efficacy of these vaccines to engage HBV immunized patients' immune system against HIV. Administration of HIVUV to blood or lymph of the HIV+ patients resulted in rapid reduction of the HIV viremia down to undetectable. It also resulted in protection of populations of CD4+ cells against HIV caused decline. CONCLUSIONS We have demonstrated the proof of concept for high efficacy of VUV, specifically HIVUV, in annihilating HIV. Nevertheless, the same compositions, processes, and methods, for persons skilled in biotechnology, pharmacogenomics, and molecular medicine, are adaptable for other deadly viral infections, which we vigorously pursue.

Abstract
Background The number of oropharyngeal lesions caused by HPV (Human papillomavirus) has been increasing worldwide in the past years. In spite of the clinical relevance of HPV infection in the anogenital tract of HIV-positive patients, the relevance of oropharynx HPV infection in these patients is not clear. The aim of the present study was to detect HPV infection, and clinical and cytological changes in the oropharynx of HIV-positive patients. Methods Samples collected from the oropharynx of 100 HIV-positive patients were subjected to hybrid capture (HC), conventional and liquid-based cytology. Clinical data were also collected to investigate the relation with HPV status. Results High and low-risk types of HPV were present in 8% and 16.7% of the total sample. The mean ± sd (maximum-minimum) of the relative ratio light unit (RLU)/cutoff (CO) was 2.94 ± 2.58 (1.09–7.87) and 1.61 ± 0.65 (1.07–2.8) for high- and low-risk-HPV, respectively. By cytology, dysplasia was not detected, but atypical squamous cells of undetermined significance (ASC-US) were diagnosed in two samples. No clinical change, suggestive of dysplasia/cancer, was detected. Conclusion Our study was able to detect and characterize HPV infection by hybrid capture, which may represent a good tool for screening and follow-up of HPV in the studied population. The frequency and viral load of HPV were low. Neither clinical nor cytological changes suggestive of dysplasia/neoplasia were observed in oropharynx of HIV-positive patients.

Abstract
Objective To identify the characteristics of clients at an HIV clinic in Mexico City who fail to collect their HIV test results and to explore the reasons for non-collection. Methods This was an exploratory, cross-sectional study that used 2016 program data from the HIV Testing and Counseling Center in Mexico City. Clients with a negative HIV-test result in 2016 were classified as collectors or non-collectors, and their sociodemographic and behavioral characteristics were compared by multivariate logistic regression. A telephone survey was conducted with individuals who failed to return for their results. Results In 2016, a total of 729 individuals obtained an HIV negative test result at the Center. Of these, 40% (n = 299) failed to collect results. In multivariate analysis, having a test requested by a physician, instead of by the individual, was the main variable associated with non-collection. The main reasons reported for not collecting were: unawareness of the collection process (23.6%, n = 21), already knowing the result (22.5%, n = 20), and scheduling difficulties (13.5%, n = 12). In all, 35% of clients were reached by telephone and 50% then returned to collect results. Conclusion Modifications to the result-delivery system are needed to increase results collection. Improving communication with clients on the collection process and with physicians that request HIV testing could be viable strategies. Alternative ways of delivering results and using rapid HIV are other possible solutions, as long as risk reduction counseling and intervention are still effectively offered.

Abstract
BACKGROUND The evaluation of quality of life related to health (HRQOL) has become an important prognostic indicator in HIV/AIDS. The aim of this study was to determine the impact of socio-demographic, clinical and psychological factors in HRQOL in a group of subjects with HIV/AIDS in northwestern Mexico and determine which variables best predict HRQOL. METHODS In a cross-sectional study with a sample of 87% of patients receiving care at a clinic for HIV/AIDS in northwestern Mexico between November 2010 to June 2011, we measure the HRQOL using the Tool Medical Outcomes Study HIV Health Survey (MOS-HIV). A model of multiple linear regression was performed to identify variables that allow us to predict HRQOL in this population. RESULTS In a sample of 54 subjects with HIV/AIDS. Patients had an average age of 43 ± 9 years, 83% were men with a mean time of 6.5 ± 4.5 years from diagnosis. HRQOL scores of physical and mental health of the participants were 57 ± 6 and 57 ± 13 respectively. In multivariate analysis, the variables that influenced the physical health punctuation were gender, marital status, sexual orientation, time since diagnosis and viral load (log). CONCLUSIONS Prospective studies are needed to better explain the influence of the factors that predict changes or trends in HRQOL in patients with HIV/AIDS.

Abstract
Background: In the era of high active antiretroviral therapy (HAART), with increasing survival of HIV patients, cardiovascular risk has emerged as a leading health issue. Aims: This study aims to predict the 10-year cardiovascular disease risk in HIV patients using the Framingham risk score and its modification for HIV-infected patients on HAART, that is, the data on adverse effect of antiretroviral drugs (DAD) prediction equation. Setting and Design: This is a case control study. Materials and Methods: The present study included 320 subjects (220 HIV infected cases and 100 age, sex and body mass index matched HIV noninfected healthy controls) and was conducted in a tertiary care centre in western Rajasthan. All the patients were subjected to a detailed clinical history, complete physical examination and evaluation of laboratory parameters. We calculated Framingham risk score and DAD prediction equation for these patients and compared these scores between patients on HAART with lipodystrophy, those without lipodystrophy, HAART naive and healthy controls. Statistical Analysis: Unpaired t-test was used and statistical analysis was performed using SPSS version 20. Results: In our study, 46.67% patients on HAART developed lipodystrophy, of which 17.72% had moderate-to-high risk of cardiovascular risk according to Framingham risk score, which is significantly higher than in patients without lipodystrophy and controls (3.3% and 6%, respectively). Similar high risk was also seen with DAD score. The various risk factors also showed a positive correlation with duration of HAART. Conclusion: Our study emphasizes the need for early recognition of cardiovascular risk in HIV-infected patients on HAART, especially in those with lipodystrophy and advocates effective use of risk calculators in these patients.

Abstract
Background: Depression is the most common mental disorder in individuals with HIV and AIDS (PLWHA), and comorbidity with depression exacerbates the disease. Several studies have estimated the prevalence of depression in HIV and AIDS patients so far, but there is no consensus about the prevalence of depression among these patients. Thus, we aimed at estimating the overall prevalence of depression among Iranian PLWHA. Methods: The international and national databases including Web of Science, Scopus, Medline, Science Direct, MagIran, Scientific Information Database (SID), IranMedex, and Medlib were searched until June 2016. The quality of included studies was assessed using Newcastle-Ottawa Scale. Results: Out of 591 references, 9 cross-sectional studies met the eligibility criteria and were included in the review. The lowest and highest reported prevalence of depression among people with HIV was 22% (95% CI: (11, 33)) and 76% (95% CI: (71, 81)), respectively. Prevalence of depression in people with HIV in the north, west, and south of Iran was 45% (95% CI: (23, 67)), 30% (95% CI: (15, 45)), and 56% (95% CI: (35, 77)), respectively. Prevalence of depression among addict and non-addict patients was 25% (95% CI: (21, 30)) and 58% (95% CI: (40, 77)), respectively. Conclusion: According to the results of this systematic review, the prevalence of depression is considerable among Iranian PLWHA. Prevalence in the southern regions of Iran is more than the western and northern regions of Iran. This evidence may be useful for Iranian health policymakers to design suitable preventive and therapeutic interventions in PLWHA to prevent and control depression among these people in Iran.

Abstract
OBJECTIVE To identify the elite of authors about the subject adherence to antiretroviral therapy; to identify the journals turned to publishing articles about adherence to antiretroviral therapy; and to identify and analyze the most commonly used words in abstracts of articles about adherence to antiretroviral therapy. METHOD A bibliometric study conducted through the Scopus base. We used articles published between 1996 and 2014, after application of the eligibility criteria, there were composed the sample with 24 articles. The data were analyzed descriptively. Were used the laws of bibliometric (Lotka, Bradford and Zipf) and the conceptual cloud map of words, through the program Cmap tools. RESULTS Lotka's Law identified the 5 authors more productive (46% of the total published). Bradford is impaired in this study. Concerning Zipf, 3 zones were determined, 31.47% of the words with in the first zone, 26.46% in the second and 42.06% in the third. In the conceptual map, the words/factors that positively and negatively influence adherence were emphasized, among them the need for more research in the health services. CONCLUSION There are few publications about the accession to antiretroviral therapy, and the scientific production is in the process of maturation. One can infer that the theme researched is not yet an obsolete topic. It should be noted that the Bibliometric was a relevant statistic tool to generate information about the publications about the antiretroviral therapy.

Abstract
Brazil is characterized by a concentrated AIDS epidemic, it has a prevalence of less than 1% in the general population. However, there are higher rates in specific populations, especially in men who have sex with men. The study's aim was to analyze the association between sociodemographic characteristics, sexual practices, sexual behaviors and the HIV infection in a group of men who have sex with men. Secondary data was collected between June 2014 and September 2015 in a research of cross-sectional design in the city of Rio de Janeiro, Brazil. Volunteers answered an online computerized questionnaire and took HIV test. Chi-squared distribution and multiple logistic regression was used. There were 341 participants. Most of them were racially mixed, single, average age of 30.6 years and with a higher education level. The HIV prevalence was 13.9%. Two logistic models were fit (insertive or receptive anal intercourse). Both models showed an association with HIV among those who had a HIV positive sexual partner (Odds Ratio ≈ 2.5) and a high self-perception of acquiring HIV (Model 1: Odds Ratio ≈ 7/Model 2: Odds Ratio ≈ 10). Low condom usage in receptive anal intercourse with casual partners had a direct association with HIV seropositivity, whereas insertive anal intercourse with casual partners with or without condoms were inversely related. The study identified a high prevalence of HIV infections among a group of men who sex with men with a high self-perception risk of acquiring HIV. The findings also showed a relation with sociodemographic and sexual behavior variables.

Abstract
The main challenges facing efforts to prevent the transmission of human immunodeficiency virus (HIV) are the lack of access to sexual education services and sexual violence against young women and girls. Vaginal formulations for the prevention of sexually transmitted infections are currently gaining importance in drug development. Vaginal mucoadhesive tablets can be developed by including natural polymers that have good binding capacity with mucosal tissues, such as chitosan or guar gum, semisynthetic polymers such as hydroxypropylmethyl cellulose, or synthetic polymers such as Eudragit® RS. This paper assesses the potential of chitosan for the development of sustained-release vaginal tablets of Tenofovir and compares it with different polymers. The parameters assessed were the permanence time of the bioadhesion—determined ex vivo using bovine vaginal mucosa as substrate—the drug release profiles from the formulation to the medium (simulated vaginal fluid), and swelling profiles in the same medium. Chitosan can be said to allow the manufacture of tablets that remain adhered to the vaginal mucosa and release the drug in a sustained way, with low toxicity and moderate swelling that ensures the comfort of the patient and may be useful for the prevention of sexual transmission of HIV.

Abstract
Negative and discriminatory attitudes towards people living with HIV/AIDS (PLWHA) are one of the biggest experienced challenges by people suffering from HIV, and these attitudes have been regarded as a serious threat to the fundamental rights of all infected people who are affected or associated with this disease in Iran. This study aimed to determine the relationship between public perception about HIV/AIDS and discriminatory attitudes toward PLWHA . The present study was conducted using a descriptive and survey design. Data were collected from 450 patients (236 male and 214 female) in Tehran and Yazd cities. The research instruments were modified HIV-related knowledge/attitude and perception questions about PLWHA, and discriminatory attitudes toward PLWHA. The results showed that prevalence of discriminatory attitudes toward PLWHA in the studied population was 60.0%. There was a significant negative correlation between citizens' awareness about HIV/AIDS, HIV-related attitudes, negative perception toward people with HIV/AIDS symptoms and their discriminatory attitudes toward PLWHA (p < .01). The hierarchical multiple regression analysis showed that components of public perception about HIV/AIDS explained for 23.7% of the variance of discriminatory attitudes toward PLWHA. Negative public perceptions about HIV/AIDS in Iran associated with discriminatory attitudes toward PLWHA and cultural beliefs in Iran tend to stigmatize and discriminate against the LWHA.

Abstract
To describe the clinical and optical coherence tomography (OCT) characteristics of ischemic maculopathy in two patients with acquired immunodeficiency syndrome (AIDS). Two patients with AIDS and cytomegalovirus (CMV) retinitis developed ischemic maculopathy. Both patients presented with central visual loss and active granular CMV retinitis. The presence of opacification of the superficial retina in the macular area and intraretinal edema suggested the diagnosis. Fluorescein angiography changes were similar in the two cases with enlargement of the foveal avascular zone and late staining of juxtafoveal vessels. OCT changes were suggestive of retinal ischemia: Increased reflectivity from the inner retinal layer and decreased backscattering from the retinal photoreceptors due to fluid and retinal edema. Ischemic maculopathy may cause a severe and permanent decrease in vision in AIDS patients. Fluorescein angiography and OCT should be considered in any patient with AIDS and unexplained visual loss. The mechanism of ischemic maculopathy may be multifactorial.

Abstract
Background: The introduction of antiretroviral therapy has caused a remarkable decrease in the occurrence of diseases and mortality among HIV-positive patients, while this success has not been achieved among injection addicts due to a low adherence to antiretroviral medicine. This study aims at clarifying the important factors affecting adherence to treatment in addicts suffering from HIV. Materials and Methods: In this qualitative research, data were gathered through in-depth interviews and field notes, and were interpreted through content analysis in the form of constant comparison. The participants were 16 drug addicts living with HIV/AIDS. Most of them had records of imprisonment and were receiving Highly Active Antiretroviral Therapy (HAART) drug treatments in the AIDS center of Imam Khomeini Hospital complex, affiliated to Tehran University of Medical Sciences. Sampling was started in a purposive method and was continued until data were saturated. Results: Four main categories including psychological reactions, contradictory beliefs, perceived support, and individual and environmental barriers were extracted from the data, each having some sub-categories. Conclusions: The obtained results indicated that adherence to the treatment of HIV is not constant and mono-dimensional, but is a function of different factors. Hence, an individual having feeble adherence in a specific time and under specific circumstances may show desirable adherence under a different circumstance. Thus, treatment of addicts living with HIV/AIDS requires physical, psychological, and social attention along with drug treatments.

Abstract
Primary effusion lymphoma (PEL) in patients with Human Immunodeficiency Virus (HIV) infection may involve pleural, pericardial, and peritoneal cavities. PEL involving the cerebrospinal fluid (CSF) is exceedingly rare, and to our knowledge has only been reported in two cases. We report another case of PEL diagnosed in CSF from a 61-year-old male with Acquired Immunodeficiency Syndrome that presented with neurological symptoms. Imaging studies of his brain showed leptomeningeal/periventricular enhancement, but no mass lesion. His CSF demonstrated human herpesvirus-8 positive pleomorphic lymphoplasmacytoid cells of null cell phenotype. This case highlights that albeit rare, PEL should be included in the differential diagnosis when large atypical cells are encountered in CSF of HIV-positive patients, even when such patients have no history of lymphoma. As in this case, ancillary studies are required to make an accurate diagnosis of PEL in CSF cytology.

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: 26328067 PMCID: PMC4552958 DOI: 10.5812/ircmj.23731] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/04/2014] [Revised: 12/21/2014] [Accepted: 03/30/2015] [Indexed: 11/16/2022]
Abstract
Sexual health and rights indicators provide essential tools for monitoring the status of individuals' sexual health and its rights, in various countries. This paper discusses sexual health and rights indicators in Iran. The indicators under study are derived from similar indicators developed by Asian-Pacific Resource and Research Center for Women, for the 15th anniversary of the International Conference on Population and Development monitoring project. Four HIV-related and three other indicators, including legal age of marriage, median age of women at marriage, and status of violence against women (VAW) were examined in this study. Iran has made several achievements in combating HIV/AIDS, with the focus on injectable drug users, and has countered a series of challenges in the determination of VAW prevalence, the increase of high risk behavior in adolescents, and sexual education for this group. The most important message of this paper is that special attention to challenging issues in Iranian individuals' sexual health could promote their current status.

Abstract
Background Cardiovascular disease in the context of human immunodeficiency virus infection has become a major clinical concern in recent years. In the current report we assess hospitalizations due to cardiovascular disease in human immunodeficiency virus patients in a Social Security reference hospital in Peru. Methods A retrospective study was carried out between January 1996 and December 2012 in a General Hospital in Lima, Peru. Results We included 26 patients hospitalized due to cardiovascular disease. Mean age was 46.3 years (SD 12.5), predominantly male (57.7%). Ten patients (38.4%) were in Acquired Immunodeficiency Syndrome stages. Seventeen (65.4%) received high-active-antiretroviral therapy. Eleven (42.3%) had cardiac involvement and 15 (57.7%) had non-cardiac vascular involvement. The most frequent causes of cardiac involvement were pericardial effusion and myocardial infarction. On the other hand, deep vein thrombosis and stroke were the most frequent for non-cardiac vascular involvement. Conclusions Cardiovascular disease is an important cause of hospitalization in Peruvian human immunodeficiency virus patients, with differences between immunosuppression stages. Further studies analyzing associated factors are warranted.

Abstract
In the United States, histoplasmosis is generally thought to occur mainly in the Ohio and Mississippi River Valleys, and the classic map of histoplasmosis distribution reflecting this is second nature to many U.S. physicians. With the advent of the HIV pandemic reports of patients with progressive disseminated histoplasmosis and AIDS came from regions of known endemicity, as well as from regions not thought to be endemic for histoplasmosis throughout the world. In addition, our expanding armamentarium of immunosuppressive medications and biologics has increased the diagnosis of histoplasmosis worldwide. While our knowledge of areas in which histoplasmosis is endemic has improved, it is still incomplete. Our contention is that physicians should consider histoplasmosis with the right constellations of symptoms in any febrile patient with immune suppression, regardless of geographic location or travel history.

Abstract
INTRODUCTION Oral lesions are among the earliest clinical manifestations of human immunodeficiency (HIV) infection and are important in early diagnosis and for monitoring the progression to acquired immunodeficiency syndrome (AIDS). The purpose of this study was to determine the prevalence of oral lesions and their relationship with a number of factors in HIV/AIDS patients attending an HIV center. MATERIALS AND METHODS A total of 110 HIV-positive patients were examined to investigate the prevalence of oral lesions according to the criteria established by the European Community Clearing House on Oral Problems Related to HIV Infection. An independent T-test was used for correlation of oral lesions with CD4+ count and a χ2 test was used for analysis of the relationship of co-infection with hepatitis B virus (HBV), sexual contact, route of transmission, history of drug abuse, and history of incarceration. RESULTS Most of the cases were male patients (82.7%). The mean age across all participants was 36.2±8.1 years. Rampant carries, severe periodontitis and oral candidiasis were the most notable oral lesions. Oral lesions were more prevalent in patients between 26-35 years of age. There was a significant difference between patients with and without pseudomembranous candidiasis and angular cheilitis according to mean level of CD4+. CONCLUSION The most common oral presentations were severe periodontitis, pseudomembranous candidiasis and xerostomia.

Abstract
The gastrointestinal (GI) tract has been increasingly affected by tuberculosis, especially in immunocompromised patients. Although strict rectal involvement is rare, the GI site mostly affected is the ileocecal region. Thus, tuberculosis should always be considered in the differential diagnosis of perianal and rectal lesions, and more so in patients infected by the HIV virus. The authors report the case of a 32-year-old man presenting a long-term history of fever, night sweats, weight loss, bloody diarrhea, fecal incontinence, tenesmus, and rectal pain. HIV serology was positive. The patient underwent anoscopy and biopsy, which disclosed the diagnosis of rectal tuberculosis. Thus the patient was referred to an outpatient clinic to follow the standard treatment.

Abstract
Perianal diseases are the most common reasons for surgery in HIV-positive patients. This study aimed to evaluate the outcomes of these surgical procedures in Korean patients, focusing on wound healing and postoperative complications. Retrospective analysis was performed on 72 HIV-positive patients who underwent surgery by a single surgeon for benign anal disease between 1998 and 2011. Of these, 68.1% (49/72) of patients received surgery for condyloma acuminata, 19.4% (14/72) for anal fistulas, 6.9% (5/72) for hemorrhoids, and 5.6% (4/72) for perianal abscesses. Patients with condyloma acuminata received surgical excision with electrical coagulation, and all wounds healed completely within 3 months, though 16.3% (8/49) of these patients experienced recurrence. Twelve of the 49 patients (24.5%) who were treated for condyloma acuminata underwent simultaneous operations for concomitant anal fistulas (n = 6), hemorrhoids (n = 4), and perianal abscesses (n = 2). Overall, 3 postoperative complications developed following a total of 94 procedures, and there was no significant increase in complication rate for patients with a low CD4+ T-cell count ( < 200/µL) compared to those with a higher count. The results demonstrate favorable results following perianal surgery in HIV-positive Korean patients.

INTERNATIONAL JOURNAL OF HIGH RISK BEHAVIORS & ADDICTION 2014; 3:e15038.

Abstract
Background: This quantitative explanatory study was designed to explain the relationship between HIV/AIDS risk-taking behaviors among African American women and their knowledge surrounding HIV/AIDS. More specifically, the research considers whether knowledge alone was sufficient to alter African-American women’s risk-taking behaviors regarding HIV/AIDS. Objectives: This study was designed to investigate knowledge surrounding sexual risk-taking behaviors including 1) heterosexual transmission; 2) low and sporadic condom usage; 3) illicit drug use; and 4) multiple sex partners associated with HIV positive and negative status among African-American women. Patients and Methods: Participants in this study were African-American women who ranged in age between 24 and 44 years. This sample of African-American women was divided into two groups according to their HIV status: 53 women who were HIV positive and 62 women who were HIV negative women. The data for this investigation were obtained through self-administered questionnaires. The t-test was used to analyze the data through the use of the windows version of the statistical package for social sciences (19.0). Results: Findings suggest that knowledge of HIV was not found to be significantly different for the HIV positive and negative groups, and thus, suggest that knowing about the consequences of risk-taking behaviors is not sufficient to alter one’s behavior among African American women. The findings from this investigation will contribute new empirical knowledge to the existing social work database on HIV/AIDS and knowledge specifically relative to African-American women. Conclusions: It was anticipated that knowledge of HIV would have been significantly higher in the HIV negative group than in the HIV positive group. However, the hypothesis was not supported by data. The HIV positive women and negative women were equally knowledgeable about HIV/AIDS.

Abstract
HIV infection is known to be associated with the development of a wide range of neoplasia. About 25 to 40% of HIV-positive patients will present some kind of malignancy in the course of the disease; among them 10% are non-Hodgkin lymphomas (NHL) and 20% of these are represented by the diffuse large B-cell lymphoma. HIV-positive patients have a relative risk of 110 times higher to develop neoplasia, than the non-infected population. The gastrointestinal (GI) tract is the most frequent extranodal site of involvement. However, the primary GI lymphoma is rare. The authors present a case of a 31-year-old male patient with a 16-year history of HIV infection, who deliberately withdrew the Highly Active Antiretroviral Therapy (HAART) regimen and was hospitalized because of a respiratory infection. Because of a long-term complaint of dyspepsia, an upper gastrointestinal endoscopy was performed disclosing a large elevated and ulcerated gastric lesion, which biopsy revealed a diffuse large B-cell lymphoma. Clinical, imaging and laboratory tests showed an early stage diagnosis: Lugano stage I. Although not frequent, the authors alert to considering this neoplasia in all HIV-positive patients with dyspeptic symptoms.
