Explaining the barriers faced by veterinarians against preventing antimicrobial resistance: an innovative interdisciplinary qualitative study.

BACKGROUND: Considering the significance of increased antimicrobial resistance (AMR) and its adverse effects on individual and social health and the important and effective role that veterinarians play in controlling this growing issue worldwide, it is essential to have effective preventive control programs. To this aim, the first step is to identify the factors behind the prevalence of AMR in Iran and the barriers veterinarians face to controlling this problem. Thus, the present study was conducted to explain the barriers veterinarians faced in the prevention of AMR from an Iranian veterinarian's perspective. METHODS: The present research was done in three cities in Iran in 2021. The data were collected through in-depth interviews with 18 veterinarians selected through purposive and snowball sampling and analyzed using conventional qualitative content analysis. RESULTS: The data analysis results were classified into 4 main categories and 44 subcategories. The former included: educational factors, administrative/legal factors, client-related factors, and veterinarian-related factors. CONCLUSIONS: The increased AMR can be approached from multiple aspects. Considering the different factors that affect the increased AMR, it is necessary to consider them all through effective planning and policy-making at multi-level and multidisciplinary dimensions. There is special attention needed to scientific and practical interventions at the individual, interpersonal, social, and even political levels. At the same time, measures should be taken to rehabilitate and maintain the health of society to strengthen supervision and attract the full participation of interested organizations.

Prevalence of acquired and transmitted HIV drug resistance in Iran: a systematic review and meta-analysis.

BACKGROUND: There is no systematic review on the prevalence of HIV drug resistance (HIVDR) in Iran. We aimed to estimate the prevalence of HIVDR among people living with HIV (PLHIV) in Iran. We assessed HIVDR prevalence in antiretroviral therapy (ART) naïve PLHIV (i.e., those without a history of ART) and PLHIV receiving ART. METHOD: We systematically searched Scopus, PubMed, Web of Science, Embase, Iranian databases (Iranian Medical Research Information System, Magiran, and Scientific Information Database), the references of studies, and Google Scholar until March 2023. A random-effects model was used to calculate a point estimate and 95% confidence interval (95% CI) for the prevalence of HIVDR in PLHIV. RESULTS: Among 461 potential publications, 22 studies were included in the meta-analysis. The pooled prevalence of acquired HIVDR in PLHIV receiving ART was 34% (95% CI: 19, 50) for nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), 27% (95% CI: 15, 41) for non-nucleoside reverse transcriptase inhibitors (NNRTIs), and 9% (95% CI: 3, 18) for protease inhibitors (PIs). The pooled prevalence of acquired HIVDR in treatment failure PLHIV was 50% (95% CI: 31, 69) for NRTIs, 49% (95% CI: 29, 69) for NNRTIs, 11% (95% CI: 2, 24) for PIs, and 1% (95% CI: 0, 4) for integrase inhibitors (INIs). The pooled prevalence of transmitted HIVDR in ART-naïve people was 3% (95% CI; 1, 6) for NRTIs, 5% (95% CI: 2, 9) for NNRTIs, and 0 for PIs and INIs. CONCLUSION: The prevalence of HIVDR was relatively high in both ART-naïve PLHIV and those receiving ART. Without universal pretreatment HIVDR testing and more frequent routine HIV viral load testing among PLHIV who are on ART, the HIVDR prevalence might increase in PLHIV in Iran.

Comparison of safety and effectiveness of antiretroviral therapy regimens among pregnant women living with HIV at preconception or during pregnancy: a systematic review and network meta-analysis of randomized trials.

BACKGROUND: Mother-to-child transmission is the primary cause of HIV cases among children. Antiretroviral therapy (ART) plays a critical role in preventing mother-to-child transmission and reducing HIV progression, morbidity, and mortality among mothers. However, after more than two decades of ART during pregnancy, the comparative effectiveness and safety of ART medications during pregnancy are unclear, and existing evidence is contradictory. This study aimed to assess the effectiveness and safety of different ART regimens among pregnant women living with HIV at preconception or during pregnancy. METHODS: We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials, and Web of Science. We included randomized trials that enrolled pregnant women living with HIV and randomized them to receive ART for at least four weeks. Pairs of reviewers independently completed screening for eligible studies, extracted data, and assessed the risk of bias using the Cochrane risk of bias tool. Our outcomes of interest included low birth weight, stillbirth, preterm birth, mother-to-child transmission of HIV, neonatal death, and congenital anomalies. Network meta-analysis was performed using a random-effects frequentist model, and the certainty of evidence was evaluated using the GRADE approach. RESULTS: We found 14 eligible randomized trials enrolling 9,561 pregnant women. The median duration of ART uptake ranged from 6.0 to 17.4 weeks. No treatment was statistically better than a placebo in reducing the rate of neonatal mortality, stillbirth, congenital defects, preterm birth, or low birth weight deliveries. Compared to placebo, zidovudine (ZDV)/lamivudine (3TC) and ZDV monotherapy likely reduce mother-to-child transmission (odds ratio (OR): 0.13; 95% CI: 0.05 to 0.31, high-certainty; and OR: 0.50; 95% CI: 0.33 to 0.74, moderate-certainty). Moderate-certainty evidence suggested that ZDV/3TC was associated with decreased odds of stillbirth (OR: 0.47; 95% CI: 0.09 to 2.60). CONCLUSIONS: Our analysis provides high- to moderate-certainty evidence that ZDV/3TC and ZDV are more effective in reducing the odds of mother-to-child transmission, with ZDV/3TC also demonstrating decreased odds of stillbirth. Notably, our findings suggest an elevated odds of stillbirth and preterm birth associated with all other ART regimens.

Efficacy of virtual reality-based training programs and games on the improvement of cognitive disorders in patients: a systematic review and meta-analysis.

INTRODUCTION: Cognitive impairments present challenges for patients, impacting memory, attention, and problem-solving abilities. Virtual reality (VR) offers innovative ways to enhance cognitive function and well-being. This study explores the effects of VR-based training programs and games on improving cognitive disorders. METHODS: PubMed, Scopus, and Web of Science were systematically searched until May 20, 2023. Two researchers selected and extracted data based on inclusion and exclusion criteria, resolving disagreements through consultation with two other authors. Inclusion criteria required studies of individuals with any cognitive disorder engaged in at least one VR-based training session, reporting cognitive impairment data via scales like the MMSE. Only English-published RCTs were considered, while exclusion criteria included materials not primarily focused on the intersection of VR and cognitive disorders. The risk of bias in the included studies was assessed using the MMAT tool. Publication bias was assessed using funnel plots and Egger's test. The collected data were utilized to calculate the standardized mean differences (Hedges's g) between the treatment and control groups. The heterogeneity variance was estimated using the Q test and I2 statistic. The analysis was conducted using Stata version 17.0. RESULTS: Ten studies were included in the analysis out of a total of 3,157 retrieved articles. VR had a statistically significant improvement in cognitive impairments among patients (Hedges's g = 0.42, 95% CI: 0.15, 0.68; p_value = 0.05). games (Hedges's g = 0.61, 95% CI: 0.30, 0.39; p_value = 0.20) had a more significant impact on cognitive impairment improvement compared to cognitive training programs (Hedges's g = 0.29, 95% CI: -0.11, 0.69; p_value = 0.24). The type of VR intervention was a significant moderator of the heterogeneity between studies. CONCLUSION: VR-based interventions have demonstrated promise in enhancing cognitive function and addressing cognitive impairment, highlighting their potential as valuable tools in improving care for individuals with cognitive disorders. The findings underscore the relevance of incorporating virtual reality into therapeutic approaches for cognitive disorders.

Prevalence of mobile phone addiction and poor mental health, and factors associated with mental health among medical students in Southeast Iran.

BACKGROUND: Mobile phone addiction is on the rise among various populations, particularly among the younger generations. This phenomenon can significantly impact various aspects of life, particularly mental health. This study aimed to examine the prevalence of mobile phone addiction and mental health, as well as the associated factors of mental health among medical students in southeast Iran in 2023. METHODS: Using stratified sampling, 365 students from the Kerman University of Medical Sciences were included from May to June 2023. The data collection tool comprised a questionnaire assessing general health (GHQ-28), mobile phone addiction, and social support. Logistic regression was used to examine the associated factors of mental health. RESULTS: The prevalence of mobile phone addiction and poor mental health among students was 46.6% (95% Confidence Intervals [CI]: 41.4; 51.7) and 52.9% (95% CI: 47.7; 57.9), respectively. The results of the multivariable logistic regression analysis indicated that individuals with mobile phone addiction had higher odds of experiencing a poor mental health situation (Adjusted Odds Ratio [aOR] = 2.01; 95% CI: 1.30, 3.09). Conversely, participants with higher social support scores were less likely to have poor health (aOR = 0.95; 95% CI: 0.94, 0.97). CONCLUSION: We found a high prevalence of mobile phone addiction. Considering the association between mobile phone addiction and mental health, it is necessary to prevent the complications and risks caused by mobile phone addiction; it requires educational planning, counseling, and behavior among vulnerable students.

Sleep quality and associated factors among people who inject drugs in Iran: a nationwide survey using respondent-driven sampling.

BACKGROUND: Poor sleep quality is a significant issue among people who inject drugs (PWID). This study aimed to evaluate sleep quality and associated factors among PWID in Iran. METHODS: Using respondent-driven sampling, 2,652 PWID (2,563 male) were recruited in 11 major cities in Iran between 2019 and 2020. The Pittsburgh Sleep Quality Index was utilized to measure sleep quality, and logistic regression was used to assess associations in RDSAnalyst, a software designed for respondent-driven sampling. RESULTS: The overall prevalence of poor sleep quality was 68.4% (68.3% among males and 70.2% among females). Married PWID had higher odds of poor sleep quality (Adjusted Odds Ratio (AOR): 1.41; 95% CI: 1.05, 1.91). Lack of access to sufficient food in the past 12 months was also associated with poor sleep quality (AOR: 1.73; 95% CI: 1.17, 2.57 for sometimes having no access, and AOR: 2.95; 95% CI: 1.93, 4.52 for always having no access compared to always having access). Additionally, good self-rated health was significantly associated with lower odds of poor sleep quality (AOR: 0.19; 95% CI: 0.11, 0.31). CONCLUSION: Poor sleep quality is prevalent among PWID in Iran. It is recommended to mitigate the adverse effects of this issue and enhance the overall quality of life for PWID. Supportive interventions aimed at preventing and treating poor sleep quality, as well as improving overall health outcomes, are essential.

A qualitative study exploring approaches, barriers, and facilitators of the HIV partner notification program in Kerman, Iran.

BACKGROUND: HIV partner notification services can help people living with HIV (PLHIV) to identify, locate, and inform their sexual and injecting partners who are exposed to HIV and refer them for proper and timely counseling and testing. To what extent these services were used by PLHIV and what are the related barriers and facilitators in southeast Iran are not known. So, this study aimed to explore HIV notification and its barriers and facilitators among PLHIV in Iran. METHODS: In this qualitative study, the number of 23 participants were recruited from November 2022 to February 2023 including PLHIV (N = 12), sexual partners of PLHIV (N = 5), and staff members (N = 6) of a Voluntary Counseling and Testing (VCT) center in Kerman located in the southeast of Iran. Our data collection included purposive sampling to increase variation. The content analysis was conducted using the Graneheim and Lundman approach. The analysis yielded 221 (out of 322) related codes related to HIV notification, its barriers, and its facilitators. These codes were further categorized into one main category with three categories and nine sub-categories. RESULTS: The main category was HIV notification approaches, HIV notification barriers, and facilitators. HIV notification approaches were notification through clear, and direct conversation, notification through gradual preparation and reassurance, notification due to being with PLHIV, notification through suspicious talking of the physician, and notification due to the behavior of others. Also, the barriers were classified into individual, social, and environmental, and healthcare system barriers and the facilitators were at PLHIV, healthcare staff, and community levels. Stigma was a barrier mentioned by most participants. Also, the main facilitator of HIV notification was social support, especially from the family side. CONCLUSIONS: The findings highlighted the multidimensionality of HIV notification emphasizing the importance of tailored support and education to enhance the notification process for PLHIV and their networks. Also, our results show that despite all the efforts to reduce stigma and discrimination in recent years, stigma still exists as a main obstacle to disclosing HIV status and other barriers are the product of stigma. It seems that all programs should be directed towards destigmatization.

Non-injection drug use among incarcerated people in Iran: Findings from three consecutive national bio-behavioral surveys.

BACKGROUND: Prisons often serve as high-risk environments for drug use, and incarcerated people are at a high risk for substance use-related mental and physical harms. This study aimed to determine the prevalence of non-injection drug use inside the prison and its related factors among incarcerated people in Iran. METHODS: We utilized data from three national bio-behavioral surveillance surveys conducted among incarcerated people in Iran in 2009, 2013, and 2017. Eligibility criteria were being ≥ 18 years old, providing informed consent, and being incarcerated for over a week. Overall, 17,228 participants across all surveys were recruited through a multi-stage random sampling approach. Each participant underwent a face-to-face interview and HIV test. The primary objective of the study was to assess self-reported non-injection drug use within the prison environment within the last month. A multivariable logistic regression model was built to determine associated covariates with drug use inside prison and an adjusted odds ratio (aOR) with 95% confidence intervals (CI) were reported. RESULT: The prevalence of non-injection drug use inside the prison was 24.1% (95% CI 23.5, 24.7) with a significant decreasing trend (39.7% in 2009, 17.8% in 2013, 14.0% in 2017; p-value < 0.001). Overall, 44.0% of those who used drugs were also receiving opioid agonist therapy (OAT) and we noted that in 2017, 75.1% of those on OAT used stimulants. In the multivariable logistic regression model, the year of interview (2013: aOR = 1.43 and 2009: aOR = 5.60), younger age (19-29: aOR = 1.14 and 30-40: aOR = 1.37), male sex (aOR = 3.35), < high school education (aOR = 1.31), having a history of previous incarceration (aOR = 1.26), and having a history of lifetime HIV testing (aOR = 1.76) were significantly and positively associated with recent non-injection drug use inside the prison. CONCLUSIONS: Approximately one in four incarcerated people in Iran reported drug use within the last month inside prisons. While a declining trend in non-injection drug use was noted, substantial gaps persist in harm reduction programs within Iranian prisons. In particular, there is a pressing need for improvements in drug treatment programs, focusing on the integration of initiatives specifically designed for people who use stimulants.

Epidemiology and spatial distribution of people diagnosed with HIV between 1997 and 2020 in Kerman, Iran.

OBJECTIVE: This study described the epidemiology and geographical distribution of people diagnosed with HIV in Kerman, Iran, between 1997 and 2020. METHODS: We used case-based HIV surveillance data of all people diagnosed with HIV in Kerman between 1997 and 2020. We compared the age, gender, modes of transmission and spatial distribution of newly diagnosed HIV-infected people in three time periods (1997-2004, 2005-2012 and 2013-2020). The χ2 test for trend, one-sample t-test and Kruskal-Wallis H test were used to compare the differences between the three time periods. We also used ArcGIS to map both HIV services and people living with HIV (PLWH) in 2020. The nearest neighbour index and kernel density were used to identify the spatial distribution of PLWH. RESULTS: A total of 459 (27.5% women) people were diagnosed with HIV during 1997-2020. The proportion of women (9.3% in 1997-2004 and 48.3% in 2013-2020, p<0.001), HIV infection through sexual contacts (11.6% in 1997-2004 and 50.3% in 2013-2020, p<0.001), HIV infection under the age of 5 years (0.8% in 1997-2004 and 5.4% in 2013-2020, p=0.01) and mean age at diagnosis among men (34.9 in 1997-2004 and 39.8 years in 2013-2020, p=0.004) significantly increased over time. 36.2% of diagnosed cases had CD4 counts under 200 x 10ˆ6/L between 2013 and 2020, with no significant improvement over time. Most newly diagnosed cases of HIV were from the eastern parts of the city. The clusters of PLWH in 2020 matched with the locations of HIV services. CONCLUSION: We observed important changes in HIV epidemiology regarding gender, modes of transmission, number of paediatric cases and density maps over time in Kerman. These changes should be considered for precise targeting of HIV prevention and treatment programmes.

Incidence, accuracy, and barriers of diagnosing healthcare-associated infections: a case study in southeast Iran.

BACKGROUND: Healthcare-associated infections (HAIs) are a threat to patients. Accurate surveillance is required to identify and prevent HAIs. To estimate the incidence rate, report the accuracy and identify the barriers of reporting HAIs using a mixed-method study. METHODS: In this quantitative study, we externally evaluated the incidence rate and accuracy of the routine surveillance system in one of the main hospitals by an active follow-up of patients from September to December 2021. We used in-depth interviews with 18 experts to identify the barriers of the routine surveillance system. RESULTS: Among 404 hospitalized patients, 88 HAIs were detected. The estimated rate of HAIs was 17.1 (95% Confidence Intervals 95: 14.1, 21.1) per 1000 patient-days follow-up. However, in the same period, 116 HAIs were reported by the routine surveillance system, but the agreement between the two approaches was low (sensitivity = 61.4%, specificity = 82.6%, negative predictive value = 89.7%, and positive predictive validity = 46.5%). The minimum and maximum positive predictive values were observed in urinary tract infection (32.3%) and surgical site infection (60.9%). The main barrier of reporting HAIs was lack of cooperation in reporting HAIs by infection control link nurses and laboratory supervisors. CONCLUSIONS: The discrepancy between the longitudinal study findings and the routine surveillance might be related to the inaccessibility of the surveillance system to clinical information of patients. In this regard, decreasing the barriers, increasing the knowledge of infection control nurses and other nurses, as well as the development of hospital information systems are necessary.

Reactogenicity within the first week after Sinopharm, Sputnik V, AZD1222, and COVIran Barekat vaccines: findings from the Iranian active vaccine surveillance system.

BACKGROUND: This study aimed to evaluate the reactogenicity effects of COVID-19 vaccines, used in Iran. METHODS: At least 1000 people were followed up with phone calls or self-report in a mobile application within 7 days after vaccination. Local and systemic reactogenicities were reported overall and by subgroups. RESULTS: The presence of one or more local and systemic adverse effects after the first dose of vaccines was 58.9% [(95% Confidence Intervals): 57.5-60.3)] and 60.5% (59.1-61.9), respectively. These rates were reduced to 53.8% (51.2-55.0) and 50.8% (48.8-52.7) for the second dose. The most common local adverse effect reported for all vaccines was pain in the injection site. During the first week after the first dose of vaccines, the frequency of the pain for Sinopharm, AZD1222, Sputnik V, and Barekat was 35.5%, 86.0%, 77.6%, and 30.9%, respectively. The same rates after the second dose were 27.3%, 66.5%, 63.9%, and 49.0%. The most common systemic adverse effect was fatigue. In the first dose, it was 30.3% for Sinopharm, 67.4% for AZD1222, 47.6% for Sputnik V, and 17.1% for Barekat. These rates were reduced to 24.6%, 37.1%, 36.5%, and 19.5%, in the second dose of vaccines. AZD1222 had the highest local and systemic adverse effects rates. The odds ratio of local adverse effects of the AZD1222 vaccine compared to the Sinopharm vaccine were 8.73 (95% CI 6.93-10.99) in the first dose and 4.14 (95% CI 3.32-5.17) in the second dose. Barekat and Sinopharm had the lowest frequency of local and systemic adverse effects. Compared to Sinopharm, systemic adverse effects were lower after the first dose of Barekat (OR = 0.56; 95% CI 0.46-0.67). Reactogenicity events were higher in women and younger people. Prior COVID-19 infection increased the odds of adverse effects only after the first dose of vaccines. CONCLUSIONS: Pain and fatigue were the most common reactogenicities of COVID-19 vaccination. Reactogenicities were less common after the second dose of the vaccines. The adverse effects of AZD1222 were greater than those of other vaccines.

Impact of maternal psoriasis on adverse maternal and neonatal outcomes: a systematic review and meta-analysis.

BACKGROUND: There is a dearth of robust evidence regarding the correlation between psoriasis with maternal and neonatal outcomes, making it challenging to establish definitive recommendations for the management of these patients. This systematic review and meta-analysis aimed to review the evidence with regard to the impact of maternal psoriasis on maternal and neonatal outcomes. METHODS: Following the PRISMA guideline, a systematic search of English articles using PubMed, Embase, Scopus, ScienceDirect, Web of Science, Google Scholar, and the Cochrane Library was conducted. The search was performed from inception to 22nd of May 2022. RESULT: A significant association was observed between psoriasis and maternal outcomes, including cesarean delivery [OR = 1.25 (95% CI: 1.13-1.30, p-value = 0.001)], (pre)eclampsia [OR = 1.29 (95% CI: 1.15-1.44, p-value = 0.0001)], gestational diabetes [Odds Ratio (OR) = 1.23 (95% Confidence Intervals (CI): 1.15-1.30, p-value = 0.001)], gestational hypertension [OR = 1.31 (95% CI: 1.18-1.45, p-value = 0.001)] and preterm birth [OR = 1.22 (95% CI: 1.10-1.35, p-value = 0.001)]. Also, there was a significant association between psoriasis and neonatal outcomes, including small for gestational age [OR = 1.07 (95% CI: 1.02-1.11, p-value = 0.053)], low birth weight [OR = 1.19 (95% CI: 1.02-1.38, p-value = 0.001)] and stillbirth [OR = 1.27 (95% CI: 1.04-1.55, p-value = 0.023)]. CONCLUSION: Maternal psoriasis could negatively impact maternal and neonatal outcomes. Our results strengthen the importance of close monitoring of the mothers' psoriasis status before and during pregnancy.

The impact of the COVID-19 pandemic on the provision of HIV/AIDS-related services in Iran: a qualitative study.

BACKGROUND: Providing services to people living with HIV (PLWH) faced many challenges during the COVID-19 pandemic. This study aimed to examine the impact of the COVID-19 pandemic on providing HIV/AIDS-related services in Iran. METHODS: In this qualitative study, the participants were included by purposive sampling between November 2021 and February 2022. Virtually focused group discussion (FGD) meetings were conducted with the first group including policymakers, service providers, and researchers (n = 17), and the interviews were conducted telephonic and face-to-face using a semi-structured guide with the second group including people who received services (n = 38). Data were analyzed by content analysis using the inductive method in MAXQDA 10 software. RESULTS: Six categories were obtained, including mostly affected services, ways of the effect of COVID-19, healthcare systems reaction, effects on social inequality, opportunities created by the pandemic, and suggestions for the future. In addition, people who received services believed the COVID-19 pandemic has affected their life in several ways, including getting COVID-19, mental and emotional problems during the pandemic, financial problems, changes in the care plan, and changes in high-risk behaviors. CONCLUSION: Considering the level of community involvement with the issue of COVID-19 and the shock caused by the pandemic, as mentioned by the world health organization, it is necessary to improve health systems' resilience for better preparedness for similar conditions.

COVID-19 knowledge, attitudes, and practices among Iranian pregnant and postpartum women: A national study.

BACKGROUND: To control the spread of COVID-19, Iran has adopted rigorous precautionary and preventive measures, particularly for vulnerable groups. Considering the effects of knowledge and attitudes about COVID-19 on adherence to preventive measures, we examined women's knowledge, attitudes, and practices (KAP) from pregnancy to 6 weeks postpartum about COVID-19 during this pandemic. METHODS: In a cross-sectional study, 7363 women were recruited via an online questionnaire between June 23, 2021 and July 7, 2021. The questionnaire consisted of 27 questions, measuring KAP. RESULTS: Most of the participants had a good understanding of COVID-19 (Mean: 7.30 out of 9, standard deviation [SD]: 1.27), but the knowledge of the disease's main symptoms and modes of transmission was at the lowest levels. The mean attitudes score was 31.47 out of 50 (SD: 7.70). The participants had good practices against COVID-19 with a mean score of 35.48 out of 40 (SD: 3.94). To reduce anxiety and fear during the pandemic, half of our participants strongly emphasized the role of family emotional support. Income status and educational levels were the most significant variables influencing KAP (p-value ≤0.001). A correlation was found between knowledge and practice scores (r = 0.205, p-value = 0.001). CONCLUSION: Our findings may serve to formulate awareness-raising interventions and can be a guide to health policymakers and workers such as obstetricians, clinicians, and midwives for more effective educational communication emphasizing the COVID-19 symptoms and transmission modes and rendering appropriate counseling, particularly on the importance of emotional family support during the pandemic.

Awareness and willingness to use HIV self-testing among people who inject drugs in Iran.

BACKGROUND: Most people who inject drugs (PWID) in Iran have not undergone recent HIV testing. While PWID face barriers when seeking HIV testing at health facilities, HIV self-testing (HIVST) could be a promising approach to improve HIV testing uptake. We examined the awareness and willingness to use HIVST among PWID in Iran. We also identified participants' characteristics associated with a higher willingness to use HIVST. METHODS: PWID were recruited in 11 cities using a respondent-driven sampling method. Willingness to use HIVST was defined as a binary variable (very low/low willingness vs. high/very high willingness). We performed multivariable modified Poisson regression to examine associated factors and report adjusted prevalence ratios (aPR) and 95% confidence intervals (CI). RESULTS: Of 2,252 PWID, 362 (16.2%; 95% CI 14.7, 17.8) had ever heard of HIVST; however, 1,658 (73.6%; 95% CI 71.7, 75.4) reported high/very high willingness to use HIVST. Willingness to use HIVST was higher among PWID who reported having a high/moderate HIV risk perception (aPR 1.22; 95% CI 1.09, 1.37), ever experiencing homelessness (aPR 1.15; 95% CI 1.03, 1.28), > 10 years of injecting history (aPR 1.16; 95% CI 1.00, 1.34), and high injection frequency in the last three months (aPR 1.18; 95% CI 1.05, 1.32). CONCLUSION: Most PWID in Iran, particularly those experiencing homelessness, have a longer injecting history, engage in more frequent injection practices, and possess a heightened perception of HIV risk would be willing to adopt HIVST. Enhancing HIVST awareness through increased access to HIVST and health education programs are needed. Additionally, conducting implementation science studies to effectively design and run HIVST programs in Iran can also increase PWID's access to HIV testing.

Double counting of clients using services in Iran: implications for assessing the reach of harm reduction programs.

BACKGROUND: Many people with high-risk sexual or injection behaviors use harm reduction services with different identities and are therefore counted more than once in client databases. This practice results in inaccurate statistics on the number of clients served and the effective reach of these services. This study aimed to determine the levels of double counting of clients of harm reduction services, including needle and syringe programs, condom distribution, HIV testing and counseling, and methadone maintenance in five cities in Iran. METHODS: Between September and March 2020, our study included 1630 clients, 115 staff of harm reduction centers, and 30 experts in the field of harm reduction in five cities in Iran. Clients of harm reduction services were asked about using harm reduction services multiple times at the same center or at different centers in the last year using different identities. Estimates of double counting derived from client responses were validated by panels of center staff and experts in harm reduction. RESULTS: Synthesizing data from clients, staff, and experts, the final estimates of double counting of clients using harm reduction services were: HIV testing 10% (95% confidence interval [CI] 0-15), needle and syringe programs 17% (95% CI 8.5-20), condom distribution programs 13% (95% CI 3-19), HIV/STI counseling 10% (95% CI 0-16), and methadone maintenance 7% (95% CI 2-10). CONCLUSION: Double counting of clients in harm reduction services in Iran is substantial. Data on clients reach by harm reduction services need to be corrected for double counting to improve program planning, client population size estimation, and efficient resource allocation.

Sexualized Substance Use among Female Sex Workers in Iran: Findings from a Nationwide Survey.

Background: Female sex workers (FSWs) are at higher risk of HIV due to high-risk sexual and drug use related behaviors. This study characterized sexualized substance use among FSWs in Iran. Methods: In 2015, 1,337 FSWs were recruited from centers for vulnerable women and through outreach efforts in 13 major cities in Iran. Data were collected via face-to-face interviews from consenting FSWs on a range of socio-demographic and behavioral characteristics. The primary outcome of interest was sexualized substance use, defined as reporting alcohol or drug use before or during sex in the past month. Bivariable and multivariable modified Poisson regression models were used to assess the correlates of sexualized substance use. Adjusted prevalence ratio (aPR) and 95% confidence interval (CI) were reported. Results: The prevalence of sexualized substance use was 31.3% (95% CI: 28.7, 34.0). Inconsistent condom use during sex with clients in the past month (aPR = 1.31; 95% CI: 1.01, 1.71), regular (i.e., at least weekly in the past month) alcohol use (aPR = 2.87; 95% CI: 2.17, 3.80), regular opioid use (aPR = 2.09; 95% CI: 1.45, 3.02), regular stimulant use (aPR = 2.68; 95% CI: 2.12, 3.39), and self-reported HIV negative status (aPR= 1.88; 95% CI: 1.14, 3.10) were significantly and positively associated with sexualized substance use. Conclusions: Sexualized substance use was associated with riskier sexual behavior and self-reported HIV sero-negativity. Harm reduction messaging to FSWs needs to go beyond focusing on sexual health promotion and further highlight the risks associated with sexualized substance use.

Ocular Trauma in Children: An Epidemiological Study.

OBJECTIVES: This study aimed to determine the epidemiology of eye injuries in children and the influential factors involved. METHODS: Eighty cases of confirmed ocular trauma were included in this cross-sectional study. Data were obtained via a checklist containing demographic information, site of the insult, the interval between the injury and physician visit, trauma mechanism, and medical history, including previous history of ocular trauma. RESULTS: Among 80 children with ocular trauma, 72.5% (n = 58) were boys. A marked preponderance (46.2%) of injuries was seen in the age group younger than 6 years. The youngest patient was a 1-year-old, and the oldest was aged 17. Most (76.25%) of the incidents occurred indoors. A total of 67.5% of accidents were induced by sharp objects (knife and glass). Most accidents occurred in spring, whereas the least number of accidents occurred in winter. The corneoscleral laceration was the most common manifestation, followed by the laceration of the iris, uveal prolapse, hyphema, and cataracts. Furthermore, rare cases of retinal detachment, hypopyon, and corneal epithelial defects were seen. CONCLUSIONS: The highest incidents of ocular trauma occurred in boys, especially those younger than 6 years. The high number of sharp object injuries is also concerning. These findings provide us with evidence that further educational interventions and supervision are required in these groups to minimize the possible devastating injuries before the opportunity even arises.

Barriers and Problems in Implementing Health-Associated Infections Surveillance Systems in Iran: A Qualitative Study.

Background: Healthcare-associated infections (HAIs) are among the most critical challenges for patients and healthcare providers. To achieve the goals of the surveillance system, it is necessary to identify its barriers and problems. This study aimed to identify the barriers and problems of the surveillance system for HAIs. Methods: This qualitative study was conducted using the content analysis method to investigate the challenges of this surveillance system from the perspective of 18 infection control nurses from hospitals in different cities of Iran with work experience of 1 to 15 years. Data were collected through semi-structured interviews and analyzed using the Lundman and Graneheim qualitative content analysis method. Results: In this study, we found 2 categories and 7 subcategories. Two categories were barriers related to human resources and organizational barriers to infection control. The 7 subcategories included weakness of medical staff in adherence to health principles, obstacles related to patients, high workload and insufficient motivation, lack of staff knowledge, lack of human resources, functional and logistical weaknesses, and weaknesses in the surveillance system. Conclusion: To reduce problems and improve HAIs reporting, the HAIs surveillance system needs the support of health system officials and managers. This administrative and support focus can establish the framework for removing and lowering other barriers, such as the number of reported cases, physician and staff noncooperation, and the prevalence of HAIs. It can also bring HAIs cases closer to reality.

Reconstruction of molecular evolution of human influenza A H1N1/2009 virus in Iran and neighboring countries.

In this study, the time and path of transmission of H1N1 serotype influenza A viruses in Iran and neighboring countries have been investigated by using Bayesian phylogeography analysis on the sequences extracted from the gene bank. We obtained all hemagglutinin (HA) and neuraminidase (NA) nucleotide sequences of influenza H1N1 available up to December 25, 2020, from Iran and its neighboring countries (i.e., Pakistan, Afghanistan, Turkmenistan, Armenia, Azerbaijan, Turkey, and Iraq). We also performed a Bayesian Markov chain Monte Carlo method to infer the evolutionary dynamic and the most recent common ancestor for the HA and NA sequences. Based on the extracted sequences, the age of emergence of H1N1 influenza virus serotype was older in Iran compared to neighboring countries, and with some degree of uncertainty, it seems Tehran had a key role and epicenter of transmission to other cities within Iran. The mean time of the most recent common ancestor of H1N1 viruses was 1989 (95% HPD: 1980-1994) for HA and NA as well. Along with ordinary measures like resource management, diagnostic approaches, and preparedness to fight against viruses that were in place, continuous monitoring, and screening of H1N1 serotype influenza virus in the country, especially by implementation of feasible, effective, and innovative measures at borderline should be initiated and identified gaps and shortage that should be a priority for virus control. It is also important for countries to have a regional monitoring program in addition to internal monitoring programs, as well as to start a virus molecular care program.
