Purpose: This study aimed to evaluate the effect of an HIV/AIDS education program for professional graduate medical school students using a teaching-learning methods. Methods: The design of this study was a nonequivalent control group pretest-posttest experiment. A total of 116 professional graduate medical school students in South Korea were included. They were randomly assigned to either a discussion-centered teaching-learning method group (n=60) or a lecture-centered teaching-learning method group (n=56). Data were collected between August and December 2015 and were analyzed using descriptive statistics, ${\chi}^2$-test, one-tailed independent t-test, one-tailed Mann-Whitney U-test, one-tailed Wilcoxon signed-rank test, and one-tailed paired t-test using SPSS WIN 19.0 program. Results: There was no statistically significant difference between the two groups with respect to HIV/AIDS knowledge, attitudes, and education satisfaction. However, the scores of knowledge and attitudes were statistically significantly increased after the education than before the education in both groups. Conclusion: To effectively improve the knowledge and attitude of HIV/AIDS, it is necessary to select an appropriate teaching-learning method for the target subjects and objectives of HIV/AIDS education.

The purpose of this study was to provide the basic data for developing a program for effective health education about AIDS (Acquired Immunodeficiency Syndrome) by investigating the knowledge and attitudes of middle and high school students about AIDS. The subjects were 476 middle school students and 658 high school students from Seoul and Kang Won province. The data were collected from November 19 to December 18. 1996. using a 56-item questionnaire. and analyzed by SAS program for t-test. x2-test. and pearson correlation coefficients. The results were as follows : 1. High school students had more knowledge than middle school students about AIDS. 2. Male. students from Seoul. and students who had drinking experience and smoking experience among middle school students. and male. students from Seoul. and students of non-coeducation among high school students were more knowledgeable about AIDS. 3. Misconceptions about the transmission of AIDS through non-intimate contact were especially common among middle school students. And a high proportion of middle and high school students knew very little about the symptoms of AIDS. 4. High school students had more positive attitudes toward AIDS than middle school students. 5. Students from Seoul and students who had smoking experience among middle school students. and students from Seoul and non-coeducation and students who had substance use experience among high school students were more positive attitudes about AIDS. 6. Most of the middle and high school students agreed that there is a need for AIDS education. 7. Middle and high school students reported that had learned about AIDS mostly from TV. Since students in the middle-school age group are especially at risk for developing AIDS­related behaviors. this study findings suggest that it is crucial to develop school-based AIDS education programs that help students acquire the knowledge and attitudes to adopt and maintain behaviors that reduce the risk of HIV (Human Immunodeficiency Virus) infection and other related health problems.

Objectives: The survival outcomes of antiretroviral treatment (ART) programs have not been systematically evaluated at the state level in India. This retrospective study assessed the survival rates and factors associated with survival among adult human immunodeficiency virus (HIV)-infected patients in Andhra Pradesh, India. Methods: The present study used data from 139 679 HIV patients aged ${\geq}15$ years on ART who were registered from 2007 to 2011 and were followed up through December 2013. The primary end point was death of the patient. Mortality densities (per 1000 person-years) were calculated. Kaplan-Meier and Cox-regression models were used to estimate survival and explore the factors associated with survival. Results: The overall median follow-up time was 16.0 months (2.0 months for the deceased and 14.0 months for those lost to follow-up). Approximately 13.2% of those newly initiated on ART died during follow-up. Of those deaths, 56% occurred in the first three months. The crude mortality rate was 80.9 per 1000 person-years at risk. The CD4 count (adjusted hazard ratio [aHR],4.88; 95% confidence interval [CI], 4.36 to 5.46 for < $100cells/mm^3$ vs. > $350cells/mm^3$), functional status (aHR, 3.05; 95% CI, 2.82 to 3.30 for bedridden vs. normal), and body weight (aHR, 3.69; 95% CI, 3.42 to 3.97 for <45 kg vs. >60 kg) were strongly associated with the survival of HIV patients. Conclusions: The study findings revealed that high mortality was observed within the first three months of ART initiation. Patients with poor baseline clinical characteristics had a higher risk of mortality. Expanded testing and counseling should be encouraged, with the goal of ensuring early enrollment into the program followed by the initiation of ART in HIV-infected patients.

Zidovudine is an antiretroviral agent prescribed for the prevention and treatment of human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS). It is typically recommended to be used in combination with other antiretroviral drugs. Zidovudine has the potential to generate N-nitrosodimethylamine (NDMA) in the presence of dimethylamine and nitrite salt under acidic reaction conditions during the drug manufacturing process. NDMA is a potent human carcinogen that may be detected in drug substances or drug products. An analytical method was developed to determine NDMA in pharmaceuticals including zidovudine using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The analysis involved reversed-phase chromatography on a Kinetex F5 column with a mobile phase comprising water-acetonitrile mixtures. The detection of positively charged ions was conducted using atmospheric pressure chemical ionization (APCI). The calibration curve demonstrated excellent linearity (r = 0.9997) across the range of 1-50 ng/mL with a highly sensitive limit of detection (LOD) at 0.3 ng/mL. The developed method underwent thorough validation for specificity, linearity, accuracy, precision, robustness, and system suitability. This sensitive and specific analytical method was applied for detecting NDMA in zidovudine drug substance and its formulation currently available in the market, indicating its suitability for drug quality management purposes.

A 73-year-old man was admitted with a sudden onset of dyspnea. He had never smoked. The chest radiograph and computed tomography revealed bilateral ground glass opacity and an enlarging perihilar consolidation with lymphadenopathies. There was a higher percentage of eosinophils (72%) in the bronchoalveolar lavage fluid (BALF) than normal. The patient was diagnosed with acute eosinophilic pneumonia and managed with steroid. Pneumocystis pneumonia (PCP) was diagnosed by an examination of the BALF, and the patient was treated with trimethoprim-sulphamethoxazole. The patient tested positive to the HIV antibody and the peripheral blood CD-4 positive lymphocyte count was only $33/{\mu}L$. The percentage of eosinophils in the BALF can increase in some cases of PCP that is complicated with AIDS. Only a few cases of eosinophilic pneumonia associated with PCP pneumonia have been reported in patients with AIDS but there are no case reports in Korea. This case highlights the need to consider PCP when the percentage of eosinophils in the BALF is elevated.

Background: Among the variety of opportunistic infections, pneumonia comprises the major morbidity in immunocompromised patients. Pneumocystis carnii pneumonia (PCP) and cytomegalovirus (CMV) pneumonia are common infectious illness of immunocompromised hosts. Although there are many reports regarding to the co-infection of PCP and CMV diagnosed by bronchoalveolar lavage (BAL) fluid examination, the effects of CMV co-infection on the outcome of PCP is still controversial. The purpose of this investigation is to evaluate the effects of CMV detected by BAL fluid examination on the clinical course of PCP in the immunocompromised patients other than human immunodeficiency virus infection. Method: Ten patients with PCP were enrolled and retrospective analysis of their medical records were done. HIV infected persons were excluded. The PCP was diagnosed by BAL fluid examination with Calcofluor-White staining. CMV was detected in BAL fluid by Shell-vial culture system. Chest radiographic findings were reviewed. We used Fisher's exact test and Mann-Whitney U test for statistical analysis of data. Results: The underlying disorders of patients were idiopathic pulmonary fibrosis (n=1), renal transplantation (n=4), necrotizing vasculitis (n=l), systemic lupus erythematosus (n=1), brain tumor (n=1), chronic myelogenous leukemia (n=1), unidentified (n=1). There were no difference in clinical course, APACHE III score, arterial blood gas analysis, white blood cell count, lymphocyte count, serum albumin concentration, chest radiographic findings and mortality between patients with PCP alone (n=4) and those with CMV co-infection (n=6). Univariate analysis regarding to the factors that associated with mortality of PCP were revealed that the application of mechanical ventilation (p=0.028), the level of APACHE III score (p=0.018) and serum albumin concentration (p=0.048) were related to the mortality of patients with PCP. Conclusion: The clinical course of PCP patients co-infected by CMV were not different from PCP only patients. Instead, accompanied respiratory failure, high APACHE III score and poor nutritional status were associated with poor outcome of PCP.
