Artificial neural network (ANN) is known to identify relationships even when some of the input data are very complex, ill-defined and ill-structured. One of the advantages in ANN is that it can discriminate the linearly inseparable data. This study presents an application of ANN to classify and predict the symptomatic status of HIV/AIDS patients. Even though ANN techniques have been applied to a variety of areas, this study has a substantial contribution to the HIV/AIDS care and prevention planning area. ANN model in classifying both the HIV and AIDS status of HIV/AIDS patients is developed and analyzed. The diagnostic accuracy of the ANN in classifying both the HIV status and AIDS status of HIV/AIDS status is evaluated. Several different ANN topologies are applied to AIDS Cost and Services Utilization Survey (ACSUS) datasets in order to demonstrate the model\`s capability. If ANN design models are different, it would be interesting to see what influence would have on classification of HIV/AIDS-related persons.

Purpose: The purpose of this study was to examine the relationships of attitudes, stigma, and moral sensitivity of nurses toward HIV/AIDS. Methods: The participants were 530 nurses working in general hospitals in South Korea. A structured questionnaire regarding attitudes, stigma toward HIV/AIDS, and moral sensitivity was used. The data were analyzed using t-tests, ANOVAs, and Pearson correlation coefficients. Results: Nurses' attitudes toward HIV/AIDS differed by job position; nurses' moral sensitivity toward HIV/AIDS differed by age, marital status, education level, clinical practice career, and job position; and nurses' stigma toward HIV/AIDS differed by age, clinical practice career, subjective economic status, HIV/AIDS education experience, and HIV/AIDS patient care experience. Attitudes of nurses toward HIV/AIDS were more negative when stigma toward HIV/AIDS was higher (r=-0.58, p<.001), these attitudes were not correlated with moral sensitivity. Conclusions: The attitudes of nurses toward HIV/AIDS were more negative when stigma toward HIV was higher, and these attitudes were not correlated with moral sensitivity. Therefore, nurses should be provided education that takes their age, marital status, clinical practice career, and experiences in HIV-related education and caregiving into account.

Purpose: The purpose of this study was to investigate the factors influencing the health-promoting behaviors of the people living with HIV. Methods: Descriptive cross-sectional study design was used. The study participants included 99 people living with HIV recruited via the Korea HIV/AIDS Network of Solidarity from May 15 to August 15, 2012. Self-report questionnaires were used fo data collection measuring perceived stress, depression, self-efficacy, health-promoting behaviors (HPLP-II), and the perceived health status. The analysis was done using SPSS/Win 18.0 program. Descriptive statistics, pearson correlation, t-test, ANOVA and stepwise multiple regressions were used for data analysis. Results: Perceived stress (r=-.21, p=.040), depression (r=-.37, p<.001), self-efficacy (r=.42, p<.001), perceived health status (r=.29, p=.003), and health-promoting behaviors were significantly correlated with each other. The self-efficacy, religion and perceived health status were significant factors, which explained about 26% of the variance of the health-promoting behaviors. Multiple regression analysis showed that a powerful predictor of health-promoting behaviors among people living with HIV was self-efficacy. Conclusion: This study suggested that a focus of nursing intervention program on self-efficacy is necessary in order to increase health-promoting behaviors among people living with HIV.

Background: The purpose of this study was to determine proportional rates of cervical precancerous lesions and cancer, and associations with socio-demographic variables, HIV status, and CD4 cell count. Materials and Methods: A retrospective comparative study was conducted targeting the medical records of all women over age 18 that were diagnosed histologically through colposcopy with cervical precancerous lesions and cancer from 1 December 2011 to 30 November 2012. Results: A total of 313 patient records were used for data analysis. The average age was 39.1 (SD=2.04) years. More than a third (37.1%) of the patients had CIN III or cervical cancer. There was a significant association between age, CD4 cell count, HIV status, and cervical lesions (p<0.05). Age was found to be an influential predictor of cervical lesions (OR=0.67, 95%CI: 0.46-0.98). Conclusions: There exists an association between age and cervical lesions, with presentation of cervical precancerous lesions and cervical cancer at a younger age among HIV reactive patients. The National Guidelines should be brought in line with the National HIV Counseling and Testing Policy to offer Pap smears to all sexually active women that test HIV reactive during routine HIV Testing.

Objectives: The purpose of this study was to characterize Indonesian women's knowledge of HIV/AIDS and to investigate the effects of socio-demographic characteristics thereupon with the goal of supporting the prevention and early detection of HIV/AIDS. Methods: This cross-sectional study was conducted using secondary data from the standard Indonesian Demographic and Health Survey (IDHS) in 2012. A total of 34 984 subjects ranged in age from 15 years to 49 years. Data were analyzed using the chi-square test and logistic regression to identify the effects of socio-demographic characteristics on Indonesian women's knowledge of HIV/AIDS. Results: All socio-demographic characteristics except marital status were related to knowledge of HIV/AIDS among Indonesian women in the univariate analysis (p<0.05). Multivariate analysis revealed that only age group, education level, location of residence, and wealth index were related to Indonesian women's knowledge of HIV/AIDS (p<0.05). Conclusions: Indonesian women's insufficient knowledge related to HIV/AIDS shows that the provision of accurate and comprehensive information related to HIV/AIDS are components of prevention and control interventions that should be improved. With greater knowledge, women are expected to be more likely to determine their own and their partners' human immunodeficiency virus status and to take appropriate preventive steps.

This paper highlights the importance of oral manifestations as indicators for early human immunodeficiency virus (HIV) detection through two case studies. HIV, responsible for acquired immunodeficiency syndrome (AIDS), damages CD4+ T-lymphocytes, leading to severe immunosuppression and increased vulnerability to various infections. Oral lesions often appear early in HIV infection and can signal disease progression. The study underscores the role of dentists in identifying these lesions, which can serve as crucial markers for HIV. We used two cases to illustrate the importance of screening in HIV patients. The first was a patient presented with oral soreness and a mass on his tongue. Despite having a positive HIV test result in a previous medical examination, but patient had intentionally concealed his infection. The second was a patient experienced dry mouth and burning sensation, with symptoms unresponsive to repeated antifungal treatments and suspected esophageal fungal infection. This led to the discovery of an HIV-positive status in a patient previously unaware of his infection. In both cases, oral manifestations played a crucial role in the early diagnosis of HIV/AIDS. These manifestations can be particularly useful for identifying HIV in patients who are asymptomatic or unaware of their status. Although oral lesions, such as oral candidiasis and oral hairy leukoplakia, are not exclusive to HIV but are more prevalent and severe in HIV-positive individuals. The findings support routine HIV screening and the critical role of dentists in recognizing oral signs of HIV infection to facilitate early diagnosis and treatment.

Purpose: This study has been conducted to identify factors that influence the initiation of treatment after the diagnosis of Korean patients with HIV. Methods: A cross-sectional study design was used, and 290 patients with HIV from outpatient departments of 7 hospitals participated. Self-report questionnaires included items on the days from the primary diagnosis to the initiation of treatment, and the patients' demographic and disease related characteristics. Negative binomial regression model (NBR) was utilized to determine risk factors influencing the initiation of treatment after the diagnosis of the patients with HIV. Results: The skewness of days was 6.62, and the degree of asymmetry of distribution was severe. In NBR, patients who were in their 40s and 50s, female, unmarried and living with their family, jobless, in a middle or high level of economic status, and diagnosed before 2014 showed a higher risk of delayed treatment than patients who were younger, male, married and living with family, in a low level of economic status, and diagnosed in 2014 or afterwards. Conclusion: The findings suggest the necessity of intervention to promote HIV patients' early entry into treatment based on the participants' characteristics.

Objectives: To identify the importance of preventing tuberculosis for HIV (Human Immunodeficiency Virus) infectees and to monitor their management of health, we investigated the proportion of HIV-TB (Tuberculosis) deaths among the HIV deaths and its related factors. Methods: Data for HIV deaths from 2002 to 2010 was acquired from Statistics Korea, after which the HIV deaths were reclassified into HIV-TB deaths or other deaths according to the KCD (Korean Classification of Diseases). We analyzed the proportion of HIV-TB deaths among HIV disease deaths and the relationship between HIV-TB deaths and related variables such as sex, age, educational level, marital status, etc. Results: There were 774 HIV deaths in South Korea between 2002 and 2010. TB was the main cause of death in 10.1% of all HIV deaths. The total proportion of HIV-TB deaths was 10.1% but its proportion reached 16.3% between 2005-2007 and then decreased to 4% in 2010. Also, the proportion of HIV-TB deaths was significantly high in the young age groups, but its proportion was significantly low in married groups and well educated groups (p<0.05). Conclusions: The result implies that the policy that takes care of HIV infectee regarding TB prevention has been getting systemized on a national scale. Also, HIV-TB deaths have been affected by social factors such as education and marriage status.

Objectives: Comorbidities increase susceptibility to severe coronavirus disease 2019 (COVID-19) infections, but limited information has been published regarding human immunodeficiency virus (HIV) and COVID-19 co-infections. This study explored the relationships among socioeconomic characteristics, sexual behaviors, and COVID-19 infection rates among Korean men who have sex with men (MSM) who are also living with HIV. Methods: Data were collected through a web survey aimed at members of the largest gay portal site in Korea, supported by the National Research Foundation of Korea (n=1005). The primary independent variables included COVID-19-related vaccinations and sexual behaviors. The dependent variable was the incidence of COVID-19 infection among respondents during the pandemic. For statistical analysis, hierarchical multiple logistic regression was performed, controlling for potential confounding variables. Results: Model I indicated that older MSM were less likely to contract COVID-19 (adjusted odds ratio [aOR], 0.98; 95% confidence interval [CI], 0.96 to 0.99). Model II demonstrated that HIV-positive MSM were nearly twice as likely to be infected with COVID-19 compared to their HIV-negative counterparts (aOR, 1.97; 95% CI, 1.14 to 3.41). Furthermore, even after accounting for COVID-19 vaccination status in model III, HIV-positive MSM continued to show a higher risk of infection (aOR, 1.93; 95% CI, 1.12 to 3.35). Conclusions: The findings of this study indicate that HIV-positive MSM are at an increased risk of contracting COVID-19, even when their vaccination status is considered. Therefore, it is essential to prioritize the prevention of COVID-19 infections in HIV-positive individuals by administering appropriate antiretroviral therapy and ensuring adherence to public health guidelines.

Objectives: Despite the importance of human immunodeficiency virus(HIV) transmission through heterosexual contact, the features of heterosexual transmission has not been well studied in Korea. So we conducted a cross sectional study to determine the transmission rates in married couples and assess risk factors for male to female heterosexual transmission of HIV. Methods: 169 HIV-infected males and their female sex partners were recruited from 1985 to tune 1998. We examined female sex partner's HIV infection status and interviewed male index partners and their female sex partners about demographic characteristics and sexual practices. We analysed heterosexual transmission rate by epidemiologic characteristics, disease status and sexual practices. And we assessed risk factors for HIV infection by univariate and multivariate analysis. Results: 30 female sex partners were infected at enrollment, yielding an transmission rate of 17.8%. Among couples who had used condoms consistently, none of the female sex partners was infected with HIV. In univariate analysis the significant risk factors were full blown AIDS status (OR=4.1, 95% CI: 1.49-11.43) and low CD4 T cell count of index partners at enrollment (OR=7.8, 95% CI: 2.19-27.80). In multivariate analysis HIV-1 RNA levels was significant risk factor when adjusted by CD4 T cell courts and mean sexual contacts per month (OR=19.2, 95% CI: 1.03-357.59) Conclusion: The risk of male to female heterosexual transmission increased with advanced stages of HIV infection in the index male partners.
