Abstract Background and Aims Acquired immune deficiency syndrome (AIDS) are a chronic and disabling disease that has a significant impact on quality of life due to weakening of physical health, financial problems and social stigma. This study aims to validate the Health‐related quality of life (HRQOL) model in people with human immunodeficiency viruses (HIV) in Iran. Methods Four hundred and fifty‐two people with HIV from Imam Khomeini Hospital between the age of 18 and 65 years (men: 308, women: 144) participated in the research. anonymously completed a battery of questionnaires, namely the Persian basic psychological need satisfaction and frustration scale, SF‐36, PSQI and mindful attention awareness scale. The method of the present study was the structural equation model. Results Current findings indicated there is a significant positive between mindfulness and need satisfaction, physical and mental health and, significant negative between mindfulness and quality and quantity of sleep. Mindfulness and need satisfaction are significant positive predictors of quality of life in people with HIV. Quality and quantity of sleep are significant negative predictors of quality of life in people with HIV. There is a positive significance between need satisfaction and physical and mental health but there is a negative significance between need satisfaction and quality and quantity. there is a negative significant between the quality and quantity of sleep with physical and mental health. Mindfulness facilitates the satisfaction of more psychological needs and improves the quality of sleep. The quality of sleep is a negative significant predictor for physical and mental health but the quantity of sleep is a negative significant predictor for physical health. Conclusion The HRQOL model can explain 18% of physical health and 16% of mental health in people with HIV in Iran. The elements of this model can be useful in evaluating and treating people with HIV in the Iranian Population. They also can use the models to plan for better services.

Abstract Introduction Since the outbreak of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) began, necessary measures to prevent virus transmission and reduce mortality have been implemented, including mandatory public use of masks, regular hand-sanitizing and hand-washing, social distancing, avoidance of crowds, remote work, and cancellation of public events. During and after the introduction of COVID-19 lockout, we performed a systematic review of available published literature to investigate the incidence of seasonal influenza and other respiratory viral infections. Methods PubMed, Embase, Web of Science, Scopus, Science Direct, Google Scholar, Research Gate, and the World Health Organization databases and websites were systematically searched for original studies concerning the impact of COVID-19 prevention means and measures on other common respiratory infectious diseases during the pandemic published by March 2021. Results The findings showed that the adherence to health protocols to prevent COVID-19 could help to reduce the incidence of other infectious diseases such as influenza, pneumonia, and Mycobacterium tuberculosis. Conclusion The implemented prevention measures and protocols might have reduced the incidence of influenza and some other common respiratory infections. However, controversies exist on this matter and future large population-based studies might provide further information to address these controversies.

Introduction: Since the epidemic of COVID-19 attracted the attention, reports were surrounding electrocardiographic changes in the infected individuals. We aimed at pinpointing different observed ECG findings and discussing their clinical significance. Methods: We conducted a systematic search in PubMed, Embase, and Scopus databases. We included eligible original papers, reports, letters to the editors, and case reports published from December 2019 to May 10, 2020. Results: The team identified 20 articles related to this topic. We divided them into articles discussing drug-induced and non-drug-induced changes. Studies reported an increased risk of QTc interval prolongations influenced by different therapies based on chloroquine, hydroxychloroquine, and azithromycin. Although these medications increased risks of severe QTc prolongations, they induced no arrhythmia-related deaths. In the non-drug-induced group, ST-T abnormalities, notably ST elevation, accounted for the most observed ECG finding in the patients with COVID-19, but their relation with myocardial injuries was under dispute. Conclusion: This systematic review suggests that identifying ECG patterns that might be related to COVID-19 is vital. Provided that physicians do not recognize these patterns, they might erroneously risk the lives of their patients. Furthermore, important drug-induced ECG changes provide awareness to the health-care workers on the risks of possible therapies.

Background and purpose: Normal amount of saliva is necessary for prevention of oral lesions, caries, and proper speech. The purpose of this research was to study the salivary flow rate in HIV-1 seropositive attending Tehran Imam Khomeini Hospital. Materials and methods: A cross-sectional study was conducted in 50 individuals including 25 HIV-1 seropositive patients (case group) and 25 healthy people (control group) attending the Counseling Center for Behavioral Diseases in Tehran Imam Khomeini Hospital, Tehran. The saliva rate was measured during 10 min. The case and control groups were matched in terms of age, gender, history of smoking, and other drugs (p< 0.9). People with history of drug abuse, alcohol, and systemic diseases were excluded from the study. Data analysis was done in SPSS. Results: Salivary flow rate in controls and case group were 4.6±0.86 ml/min and 3.6±1.8 ml/min, respectively. In the case group, the salivary rate was significantly lower than that of the control group (p= 0.01). Moreover, significant associations were seen between salivary flow rate and educational level (p

Pulmonary hypertension is rare but is one of the complications that occur due to HIV infection. Symptoms of HIV-associated pulmonary arterial hypertension are often non-specific but the main symptom of the disease is dyspnea. In this cross-sectional study, we measured systolic pulmonary arterial pressure (SPAP) by echocardiographic methods among HIV-positive patients who received ART. This research is a descriptive, cross-sectional study of 170 HIV-positive patients that was conducted in Imam-Khomeini hospital, Tehran, Iran during 2011-2013. All patients regularly received antiretroviral therapy at least for recent 2 years. There were not any cardiopulmonary symptoms (cough, dyspnea, exertional fatigue and chest discomfort) in these patients. All participants underwent echocardiography to estimate SPAP. The participants comprised 108 males (63.5%) and 62 females (46.5%). The mean age of patients was 41 years old, and the mean duration of HIV infection was 5.5 years. The mean CD4 cell count was 401 cell/µl. The principal regimen of antiretroviral therapy included two nucleoside reverse transcriptase inhibitor (NRTI) and one non-nucleoside reverse transcriptase inhibitor (NNRTI) in the hospital. The mean of systolic pulmonary arterial pressure was 25 mmHg in the participants; 156 (93.4%) of them had SPAP ≤ 30 mmHg (normal), six (3.6%) had SPAP: 31-35 mmHg (borderline) and five (3%) had SPAP > 35 mmHg (pulmonary hypertension). Our results indicated a significant increase of pulmonary hypertension in asymptomatic HIV-positive patients that had no association with any other risk factor. Also, antiretroviral therapy was not a risk factor for pulmonary hypertension in this study.

Background: The aim of this study was to evaluate the prevalence of HIV infection in Iranian long distance truck drivers using rapid HIV test. Methods: The study included 400 consecutive participants in Bazargan city, north-west of Iran in the late 2008 and the early 2009. Results: No HIV infection was observed among these long distance truck drivers. Conclusions: Although results of this study is plausible compared to other similar studies, repeated surveys are necessary to know the trend of HIV infection in truckers in Iran.

BACKGROUND: The rate of human immunodeficiency virus type 1 (HIV-1) infection in Iran has increased dramatically in the past few years. While the earliest cases were among hemophiliacs, injection drug users (IDUs) fuel the current epidemic. Previous molecular epidemiological analysis found that subtype A was most common among IDUs but more recent studies suggest CRF_35AD may be more prevalent now. To gain a better understanding of the molecular epidemiology of HIV-1 infection in Iran, we analyzed all Iranian HIV sequence data from the Los Alamos National Laboratory. METHODS: All Iranian HIV sequences from subtyping studies with pol, gag, env and full-length HIV-1 genome sequences registered in the HIV databases (www.hiv.lanl.gov) between 2006 and 2013 were downloaded. Phylogenetic trees of each region were constructed using Neighbor-Joining (NJ) and Maximum Parsimony methods. RESULTS: A total of 475 HIV sequences were analyzed. Overall, 78% of sequences were CRF_35AD. By gene region, CRF_35AD comprised 83% of HIV-1 pol, 62% of env, 78% of gag, and 90% of full-length genome sequences analyzed. There were 240 sequences re-categorized as CRF_AD. The proportion of CRF_35AD sequences categorized by the present study is nearly double the proportion of what had been reported. CONCLUSIONS: Phylogenetic analysis indicates HIV-1 subtype CRF_35AD is the predominant circulating strain in Iran. This result differed from previous studies that reported subtype A as most prevalent in HIV- infected patients but confirmed other studies which reported CRF_35AD as predominant among IDUs. The observed epidemiological connection between HIV strains circulating in Iran and Afghanistan may be due to drug trafficking and/or immigration between the two countries. This finding suggests the possible origins and transmission dynamics of HIV/AIDS within Iran and provides useful information for designing control and intervention strategies.

Background: HIV/AIDS is one of the diseases which not only makes threats to physical health, but also, due to the negative attitudes of people and the social stigma, affects the emotional and social health of patients. The aim of this study was to identify the psychological, social, and family problems of people living with HIV/AIDS (PLWHA) in Iran. Methods: In this qualitative study, we used purposive sampling to enroll PLWHA, their families, and physicians and consultants in two cities of Kermanshah and Tehran. Each group of PLWHA, their families, physicians, and consultants participated in two focus group discussions (FGDs), and a total of eight FGDs were conducted. Six interviews were held with all key people, individually. Results: Based on the views and opinions of various groups involved in the study, the main problems of PLWHA were: Ostracism, depression, anxiety, a tendency to get revenge and lack of fear to infect others, frustration, social isolation, relationship problems, and fear due to the social stigma. Their psychological problems included: Marriage problems, family conflict, lack of family support, economic hardships inhibiting marriage, and social rejection of patient′s families. Their family problems were: Unemployment, the need for housing, basic needs, homelessness, and lack of social support associations. Conclusions: It seems that the identification and focusing on psychological, social, and family problems of affected people not only is an important factor for disease prevention and control, but also enables patients to have a better response to complications caused by HIV/AIDS.
