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.

Global trend analysis of diabetes mellitus incidence, mortality, and mortality-to-incidence ratio from 1990 to 2019.

Diabetes Mellitus (DM) is a common chronic disease and a public health challenge worldwide. The present study aimed to analyze the trend in DM incidence, mortality, and mortality-to-incidence ratio (MIR) world over 30 years. The age-standardized DM incidence and mortality rates for both genders and different countries of the world from 1990 to 2019 were extracted from the Global Burden of Disease (GBD) study and the Human Development Index (HDI) was obtained for all countries from the United Nations Development Program (UNDP) database. The mean trends for the indicators for developing countries, developed countries, and all countries were evaluated using Generalized Estimating Equations (GEE) and the spline model. The estimates showed that the global mean trend of DM incidence from 1990 to 2019 followed an upward trend with an annual increase of 3.73 cases per 100,000 people. The global mean of DM mortality followed an upward trend with an annual increase of 0.43 cases until 2005 followed by a downward trend after this year with an annual decrease of 0.14 and the global mean MIR followed a downward trend during the same period with an annual decrease of 0.001 per 100,000 people. Besides, the mean incidence of DM in developing countries followed an upward trend similar to the trend in developed countries. Additionally, the mean mortality rate due to DM in developing countries increased with a slope of 0.62 until 2005 and then decreased with a slope of 0.02, and the mean MIR trend in the developed and developing countries showed a downward trend. Thus, developed countries followed a relatively faster decrease in MIR than developing countries.The data from the present study show the increased incidence of DM has made it one of the most important health concerns in the world, and if this issue is not addressed, this disease can cause more concerns for communities in the coming years. This being so, more DM prevention and control programs need to be put into practice.

Prevalence of HIV, hepatitis B virus, hepatitis C virus, drug use, and sexual behaviors among street children in Iran: A systematic review and meta-analysis.

Background and Aims: Street children face a disproportionately higher risk of human immunodeficiency virus (HIV), hepatitis B virus (HBV), and hepatitis C virus (HCV) due to high-risk sexual and drug use practices. We aimed to estimate the prevalence of these infections and related risk behaviors among street children in Iran. Methods: We searched PubMed, Web of Science (ISI), Embase, Scopus, and Google Scholar for the English-language records and Iranian databases, including SID, Magiran, and IRANDOC for the Farsi-language records up to September 18, 2022. Random effects analysis was used to obtain prevalence estimates for each condition. Homogeneity across included studies was assessed using I 2. Results: We extracted data from 18 eligible studies, representing 5646 children (83.2% boys), with a mean age of 10.2 (range: 5-18). The prevalence of HIV, HBV, and HCV were 0.79% (95% confidence intervals [CIs]: 0.0-5.56), 1.97% (95% CI: 1.01-3.19), and 1.88% (95% CI: 0.74-3.46), respectively. The prevalence of lifetime drug use and sexual abuse was 8.32% (95% CI: 4.83-12.62) and 10.18% (95% CI: 3.02-20.67) among street children, respectively. Conclusion: The estimated prevalence of HIV, HBV, and HCV among street children in Iran was higher than the estimates in the general population. Moreover, drug use and the experience of sexual abuse were prevalent among this population. These findings suggest the need for targeted prevention programs for street children in Iran.

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.

Correlates of quality of life and mental health among youth experiencing homelessness in Iran.

BACKGROUND: Quality of life (QOL) and mental health among marginalized populations, including people experiencing homelessness in Iran, are understudied. We assessed the QOL and mental health status as well as their associated factors among youth experiencing homelessness in Kerman, Iran. METHOD: We recruited 202 participants using a convenience sampling method from 11 locations, including six homeless shelters, three street outreach sites, and two drop-in service centers, from September to December 2017. Data were collected using a standardized questionnaire that included QOL, mental health, demographics, drug use, and sexual behaviors questions. Scores in each domain were indexed with a weight of 0-100. The higher score indicated a higher QOL and mental health status. Bivariable and multivariable linear regression models were performed to examine correlates of QOL and mental health. RESULT: The mean (SD) score of QOL and mental health were 73.1 (25.8) and 65.1 (22.3), respectively. Multivariable analysis showed that youth experiencing homelessness who were aged 25-29 years old (ß = -5.4; 95% CI: -10.51; -0.30), and lived on the streets (ß = -12.1; 95% CI: -18.19; -6.07) had a lower mental health score. Moreover, those who had higher education (ß = 5.4; 95% CI: 0.58; 10.38), had no history of carrying weapons (ß = 12.8; 95% CI: 6.86; 18.76), and had a higher QOL score (ß = 0.41; 95% CI: 0.31; 0.50) had a higher mental health score. CONCLUSION: This study highlights that QOL and mental health among youth experiencing homelessness in Iran are concerning, particularly among those who were older, were less educated, were living on the street, and had a history of carrying a weapon. Community-based programs, including mental health care and affordable housing are needed to improve QOL and mental health among this population in Iran.

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.

The Impact of COVID-19 on Disruptions of HIV-related Services: A Rapid Review.

Background: People living with HIV (PLHIV) and those at risk of HIV are marginalized worldwide and need to reach services regularly. The COVID-19 pandemic can disrupt the HIV care continuum. This study aimed to identify the extent to which HIV-related services have been affected by the COVID-19 pandemic and how we can overcome these challenges. Methods: In this rapid review, we systematically searched PubMed and Scopus databases, the references of studies, international agencies, and studies "cited by" feature in google scholar till May 28, 2021, without restrictions to language. Results: Among the total of 1,121 studies, 31 of them were included in the review. The most important HIV-related services affected by the COVID-19 pandemic were; access to anti-retroviral drugs, HIV testing, periodic HIV-related testing in people living with HIV (PLHIV), pre-exposure prophylaxis, post-exposure prophylaxis, harm reduction services, psychological and counseling services. Some factors were introduced to mitigate the effects of these challenges, including increasing the resilience of health, protecting health care workers and their clients against COVID-19 through vaccination, providing HIV-related services through telehealth, and multi-month dispensing (MMD) of medicines. Conclusion: The results of this review study showed that PLHIV had difficulty in accessing follow-up, care and treatment services during the COVID-19 pandemic. Programs such as the MMD or telemedicine can be useful in providing services to PLHIV during the pandemic.

Designing and Launching Health Observatory Dashboard of Islamic Republic of Iran.

Background: Health observatory dashboard can assist in promoting the quality of academic and governmental services by generator high-quality information. The aim of this research is to describe the stages of designing and launching the national public health dashboard. Methods: This study was conducted with a qualitative approach and designing a web application using C#, ASP.NET and JQuery languages. The required data were gathered via 2 sources: (1) reviewing existing documents, and (2) gathering expert opinions. Results: The dashboard is developed in 3 sections, including a conceptual model of the indicators, a page for selecting the indicators, and metadata of each indicator. The indicators are demonstrated in 3 classes based on data sources (surveys and routine data collection), health effects (mortality, morbidity, risk factors, service coverage, social factors affecting health, health system functions, financial protection, population indicators, and macro indicators), as well as a plan, including the health reform plan. The page for selecting the indicators includes 190 major indicators encompassing the 3 mentioned areas. The metadata of each indicator includes the indicator name, its definition, its last figure, its source, the section for descriptive and comparative diagrams (the indicator's trend, provincial distribution, and international comparison of the indicator), and policy options. Conclusion: The Health Observatory System of Iran has been launched. The credibility of this system and user satisfaction depends on implementation of the health observatory calendar, qualitative control of the path of the recorded data, and national determination of policymakers.

The effect of vitamin D on recurrence of uterine fibroids: A randomized, double-blind, placebo-controlled pilot study.

BACKGROUND: and purpose: A deficiency of vitamin D has been suggested as one of the principal risk factors for uterine fibroids (UFs). We aimed to investigate the effect of vitamin D supplementation on the recurrence of UFs. MATERIALS AND METHODS: In a randomized, double-blind, placebo-controlled pilot study, women who had undergone hysteroscopic myomectomy from November 2017 to June 2020 were randomly given either vitamin D (1000 IU tablet; n = 55), or placebo (n = 54) daily for 12 months. Both groups were followed and compared in regard of the primary outcomes of the study, which were recurrence rates, size, and numbers of UFs based on three-dimensional transvaginal ultrasound investigation (3D-TVS). Data analysis was performed by the intention-to-treat (ITT) approach. RESULTS: The mean age of the study participants was 37.9 ± 6.5 years. The two groups did not differ significantly in terms of demographic and pre-intervention clinical characteristics. The administration of vitamin D supplements for one year reduced recurrence rates of UFs by 50% (p = 0.17). Vitamin D also reduced the size of recurrent UFs in the intervention group compared to controls (-7.7 mm), the difference was statistically different (p < 0.001). No adverse effect of vitamin D was reported in the present study. CONCLUSION: Based on these results, vitamin D appears to be a promising and safe agent in the prevention of recurrence and reduction of the size of recurrent UFs, although further well-designed and appropriately powered studies are required to demonstrate a significant difference in the size and number of recurrent UFs.

Cytotoxic abietane-type diterpenoids from roots of Salvia spinosa and their in Silico pharmacophore modeling.

The roots of Salvia spinosa L. (Lamiaceae) were extracted with hexane, dichloromethane (DCM) and ethyl acetate. The DCM extract exhibited cytotoxic activity (IC50 32.7 µg/mL) against MFC-7 breast cancer cell line in MTT colorimetric bioassay. Ferruginol (1), taxodione (2), 12-deoxy-6-hydroxy-6,7-dehydroroyleanone (3), 14-deoxycoleon U (4), 15-deoxyfuerstione (5) and taxodone (6) were isolated from the DCM roots extract. Their structures were elucidated by a combination of spectroscopic analyses including EIMS and 1H- and 13C NMR spectra. The cytotoxicity of compound 3 was determined against MCF-7 and K562 cell lines and compared with the other compounds. A pharmacophore model was built based on potent input compounds to resolve important pharmacophore features responsible for cytotoxic activity of the isolated compounds.

Association between internet addiction and loneliness across the world: A meta-analysis and systematic review.

There might be an association between Internet addiction (IA) and loneliness; however, inconsistent evidence suggests that the severity of this association remains unclear. This study was conducted to assess the association between IA and loneliness. A systematic literature search was conducted in four online databases, including PubMed (MESH terms), Web of Science, Scopus, and Embase. Observational studies measuring the association between IA and loneliness were screened and included in this review. A meta-analysis was conducted using the Stata software. Twenty-six articles with a total sample size of 16496 subjects were included in the analysis. A moderate positive association (r = 0.15 (95% CI: 0.13, 0.16)) was found between IA and loneliness. The individuals with IA had significantly higher scores of loneliness. According to this meta-analysis, we need more attention to the early symptoms of loneliness in individuals with IA. Longitudinal studies are needed to determine the temporality of this association considering adjustment for time varying confounders.

A study of Happiness in the Islamic Republic of Iran's work communities.

Background: Happiness, a factor in social, political, and economic development, leads to higher performance, increase in production, and great efficiency. The goal of this study was to assess the level of happiness in Iran's work communities. Methods: In this cross-sectional survey study, we randomly selected 13842 people from 380 workplaces in 31 provinces of Iran. Trained interviewers based on structured questionnaires collected data. Reliability of the questionnaire determined by using internal consistency. Collected data were analyzed through SPSS 16 software (SPSS Inc., Chicago, IL) and the charts and tables were prepared to indicate each province's happiness level and the national mean. Results: Average age of employees was 35.4±7.78 years. The majority of the respondents were male(n=11835, 85.5%), had finished middle/secondary school (n=7142, 51.6%) and were married (n=11323, 81.8%). The level of happiness varied from the highest value 148.97±21.49 in Boushehr Province and the lowest 130.39± 25.28 in Hormozgan Province. The mean ± SD value of happiness in the work communities of Iran was 141.22±22.89. Conclusion: Policymakers should consider workers' happiness as an effective factor in production and efficiency.

Superior hypogastric plexus block as an effective treatment method for endometriosis-related chronic pelvic pain: an open-label pilot clinical trial.

We aimed to investigate the effect of superior hypogastric plexus (SHP) block on pain relief and quality of life of patients with refractory endometriosis. Sixteen patients with refractory endometriosis underwent SHP block. The outcome measures included visual analogue scale (VAS) for chronic pelvic pain, VAS for dysmenorrhoea, and VAS for dyspareunia. The short-form endometriosis health profile (EHP-5) was used to measure quality of life. All the outcome measures were evaluated at weeks 0, 1, 4, 12 and 24. The mean baseline VAS scores significantly improved after the SHP block (p < .001 for all). The mean overall EHP-5 score also significantly improved from 54.3 ± 18.2 to 24.6 ± 13.3 (p < .001). The positive effects of SHP were not diminished over time. No serious adverse effect was noticed in any of the patients. Preliminary results suggest that SHP block could be used as an effective method in pain control and improvement of quality of life in refractory endometriosis.IMPACT STATEMENTWhat is already known on this subject? Safety and efficacy of SHP block in the treatment of CPP has been revealed in earlier investigations. However, the efficacy of SHP block for pain management in patients with refractory endometriosis has not been investigated in earlier investigations.What do the results of this study add? SHP block is an effective method for pain control and improvement of quality of life in patients with refractory endometriosis. The positive effects of this treatment did not diminish over 24-weeks follow-up of the study. No serious adverse effect was noticed in any of the patients.What are the implications of these findings for clinical practice and/or further research? Preliminary results suggest that SHP block could be used safely and effectively for controlling pain and improvement of quality of life in patients with refractory endometriosis.

Prevalence of methicillin-resistant Staphylococcus aureus in Iranian children: a systematic review and meta-analysis.

BACKGROUND: Antibiotic resistance is associated with longer hospitalizations, higher treatment costs, and increased morbidity and mortality rates. PURPOSE: This study aimed to determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in Iranian children. METHODS: International databases, including Web of Science, PubMed, Embase, and Scopus, and Iranian databases, including Scientific Information Database (www.sid.ir), Magiran, and Iranian Database for Medical Literature (idml.research.ac.ir), were systematically searched for articles published between January 2000 and August 2019. Sources of heterogeneity were determined using subgroup analysis and meta-regression. RESULTS: Overall, 343 studies were identified; of them, 20 were included in the meta-analysis to estimate the pooled prevalence. The pooled prevalence of MRSA was 42% (95% confidence interval [CI], 29-55) among culture-positive cases of S. aureus, 51% (95% CI, 39-62) in hospitalized children, and 14% (95% CI, 0.05-27) in healthy children. CONCLUSION: The overall pooled prevalence of MRSA in children was 42%. Appropriate infection control measures and effective antibiotic therapy are needed.

COVID-19 Among People Living with HIV: A Systematic Review.

This systematic review summarizes the evidence on the earliest patients with COVID-19-HIV co-infection. We searched PubMed, Scopus, Web of Science, Embase, preprint databases, and Google Scholar from December 01, 2019, to June 1, 2020. From an initial 547 publications and 75 reports, 25 studies provided specific information on COVID-19 patients living with HIV. Studies described 252 patients, 80.9% were male, the mean age was 52.7 years, and 98% were on antiretroviral treatment (ART). Co-morbidities in addition to HIV and COVID-19 (multimorbidity) included hypertension (39.3%), obesity or hyperlipidemia (19.3%), chronic obstructive pulmonary disease (18.0%), and diabetes (17.2%). Two-thirds (66.5%) had mild to moderate symptoms, the most common being fever (74.0%) and cough (58.3%). Among patients who died, the majority (90.5%) were over 50 years old, male (85.7%), and had multimorbidity (64.3%). Our findings highlight the importance of identifying co-infections, addressing co-morbidities, and ensuring a secure supply of ART for PLHIV during the COVID-19 pandemic.

A National survey on substance use among Iranian industrial workers.

Background: Recent evidence shows that the prevalence of substance abuse is 2.1% in Iranians aged 15-64 years, while reported rates are higher in studies that target industrial workplaces. Our study intends to provide a national picture of substance use among industrial workers in Iran. Methods: This survey was designed to collect data through interviews and dipstick urine tests. Using a multi-stage sampling approach, we recruited our study subjects from a representative sample of industrial workers from all provinces in 2015. Data were weighted to estimate the prevalence rate of substance use. Odds ratios were calculated through adapting logistic regression to test the strength of association between substance use (based on self-report and urine test) and sociodemographic factors including sex, age group, education level, marital status and worker's professional training status. All statistical analyses were conducted using SPSS Version 22. P <0.05 was considered significant. Results: We analyzed the data collected from 13,128 participants; both self-reported use and urine test results. Majority of the respondents were male (n=12077, 92%), aged 21-40 years old (n=9491, 72.3%), had finished middle/secondary school (n=8353, 63.6%) and were married (n=11012, 83.9%). Opium was the most popular abused substance (n=352, 2.7%) followed by alcohol (304, 2.3%), based on self-reports. Urine tests showed that 23.8% (n=3105) of the participants had a positive result for the use of opiates/opioids, crystal meth and/or cannabis. The highest rate of substance use reported from a province was 60.50%; the lowest provincial rate was 9.0%. Conclusion: Nearly a one-fourth of Iranian industrial employees are engaged in use of substances with significant geographical distribution. Urine test is the recommended method to assess the prevalence of drug use among industrial workers in Iran.

Health Status in the Islamic Republic of Iran, Middle East and North Africa Countries: Implications for Global Health.

BACKGROUND: The aim of this study was to evaluate the health status of the Iranians following the sustainable development goals' (SDGs) introduction and the recent health reform implementation in Iran and to compare with those of the Middle East and North Africa region (MENA) and global average. METHODS: This comparative study used secondary data to investigate socio-demographic and health status indicators. The sources included census, population-based surveys and death registries. Global and regional health status indicators were obtained from international databases including WHO, the World Bank and the Institute for Health Metric and Evaluation (IHME). RESULTS: Life expectancy and human development index improved following the reform implementation. Among causes of death, 74.6% were attributed to non-communicable diseases (NCDs). There was an increasing trend in risk factors for NCDs in Iran, while at the same time neonatal, infant and under-5 mortality rates reduced. Compared to the MENA, Iran has a lower maternal mortality ratio, neonatal, infant, and under-5 mortality rates, and a higher life expectancy. NCDs and road traffic injuries accounted for a larger portion of disability-adjusted life years in Iran compared to the MENA and worldwide. CONCLUSION: Actions against communicable diseases and road traffic injuries are required together with continued efforts to address NCDs. Although based on the results, Iran has relatively high rankings, there is a need to develop a roadmap to accelerate achieving global health goals and SDGs targets.

One-Step Resection via Hysteroscopic Myomectomy and Prostaglandin F2α for Large Submucosal Myoma.

STUDY OBJECTIVE: To assess the efficacy of prostaglandin F2α (PGF2α) in hysteroscopic myomectomy of submucous myomas. DESIGN: Single-blind, randomized clinical trial study. SETTING: Teaching hospital, affiliate of Iran University of Medical Sciences, Tehran, Iran. PATIENTS: Forty-four patients with symptomatic submucous myomas were randomly assigned to the intervention group (n = 21; 1 excluded owing to myoma not identified on pathologic examination) and the control group (n = 22). INTERVENTIONS: In the intervention group, PGF2α was injected into the cervix twice: before the beginning of the surgery and after the resection of the intrauterine portion of the submucous myoma. TIn the control group, the myomas were resected without the PGF2α injection. The same procedure was performed in the control group without the PGF2α injection. MEASUREMENTS AND MAIN RESULTS: There were no differences in the demographics, size, or type of myomas among the groups at baseline. Although the proportion of complete removal of the submucous myomas in the intervention group (PGF2α) was higher (20/23 myomas or 87%) than that in the control group (15/23 myomas or 65.2%), the difference was not significant (p = .1). The number of 1-step complete removal of large submucous myomas (>5 cm) in the PGF2α group was significantly higher than that in the control group (8/10 myomas [80%] vs 2/8 myomas [25%], p = .03). The mean duration of operative time was significantly longer in the intervention group than in the control group (p = .01). The intervention group experienced more days of postoperative bleeding than the control group (p = .001). There were no differences regarding the length of stay at the hospital or hemoglobin levels between the groups (p = .07). CONCLUSION: In the current study, injection of PGF2α was beneficial for 1-step complete resection of large (>5 cm) submucous myomas via hysteroscopic myomectomy.

Study of the mechanism of action, molecular docking, and dynamics of anticancer terpenoids from Salvia lachnocalyx.

Among specialized metabolites, terpenoids are well-known for their cytotoxic activity. Several of them have been isolated from sage plants and assayed for their potential therapeutic use against cancer. In this study, we report the effects of three potent anticancer terpenoids previously isolated from Salvia lachnocalyx, including geranyl farnesol (1), sahandinone (2), and 4-dehydrosalvilimbinol (3) on cancer cell cycle alterations and reactive oxygen species (ROS) production. Interactions of compounds 1-3 with topoisomerase I were also investigated by using molecular docking and dynamics simulation. Accumulation of cells in sub-G1 phase of the cell cycle indicated that all tested compounds induce apoptosis in MOLT-4 cancer cells. Measurement of ROS production demonstrated that this mechanism is not involved in the induction of apoptosis. We suggest topoisomerase I inhibition as the mechanism of cytotoxic activity of compounds 1-3 based on docking and molecular dynamics (MD) calculations. These natural terpenoids could be considered as good candidates for further development as anticancer agents.

Incidence of Colorectal Cancer and Adenomatous Polyps After a Two-Step Screening in Isfahan Province, Iran in 2018.

PURPOSE: The aim of this study was to estimate the incidence of colorectal cancers in Iran. The results of this study are based on a screening program that is being implemented in Isfahan province. MATERIAL AND METHODS: In this study, about 137,000 people were screened for colorectal cancer and adenomatous polyps in 2 steps during the year 2018. RESULTS: Based on the findings of this study, the incidence of adenomatous polyps was reported to be 389 (95% CI, 365-422) per 100,000 population. The incidence of adenomatous polyps was reported to be 483 (95% CI, 446-520) and 316 (95% CI, 286-346) in men and women, respectively (p < 0.001). Also, the incidence of colorectal cancer was reported to be 33 (95% CI, 23-42) per 100,000 population. The incidence of colorectal cancer in men and women was reported to be 41 (95% CI, 30-51) and 26 (95% CI, 17-34), respectively, indicating a statistically non-significant difference (p = 0.29). CONCLUSION: Based on the result of this study, despite a low participation rate of the target population in the screening program, the incidence of adenomatous polyps and colorectal cancer is relatively high in the average-risk population.
