Knowledge of the epidemiology of the disease is essential in planning for prevention. So this study aimed to investigate the epidemiological aspects of gastric cancer including prevalence, incidence, mortality, and risk factors of Iran.Methods: This systematic review study was based on articles published in both English and Persian languages during the years of 1970– 2020 in international databases (PubMed, Web of Science, Scopus) and national databases (including SID, Magiran, and IranDoc). Papers related to epidemiological aspects of the disease including mortality, prevalence, incidence, and risk entered the final review.Results: According to the studies, the minimum and maximum prevalence of gastric cancer in northwestern Iran (Ardabil) is between 0.2 and 100 per 100,000. Also, the death rate per 100,000 people ranged from 10.6 to 15.72 and the ASMR ranged from 4.2 to 32.2%. On the other hand, the incidence of GC was higher in men than in women (74.9 vs 4.6%). The GC risk ratio was 8-times higher in the elderly than in the other age groups (HR=8.0, 2.7– 23.5). The incidence of gastric cancer in patients with H. pylori infection was 18-times and that of smokers 2-times higher than other populations. Low level of economic situation and food insecurity increased the odds of GC by 2.42- and 2.57-times, respectively. It should be noted that there was a direct relationship between consumption of processed red meat, dairy products, fruit juice, smoked and salty fish and legumes, strong and hot tea, and consumption of salt and gastric cancer incidence. There was also an inverse relationship between citrus consumption, fresh fruit, garlic, and gastric cancer. In addition, the mRNA genes are the most GC-related genes.Conclusion: Given the high incidence of GC in Iran, changing lifestyle and decreasing consumption of preservatives in food, increasing consumption of fruits and vegetables, and improving the lifestyle can be effective in reducing the incidence of this disease.Keywords: epidemiology, gastric cancer, Iran, risk factor, systematic review

Using a probabilistic bias analysis method, the association between smoking and breast cancer was adjusted for the bias resulting from misclassification of smoking secondary to self-reporting as well as a minimally sufficient adjustment set of confounders derived from a causal directed acyclic graph (cDAG). Population attributable fraction (PAF) for smoking was calculated using Miettinen’s formula.Results: While the odds ratio (OR) from the conventional logistic regression model between smoking and breast cancer was 0.64 (95% CI: 0.36– 1.13), the adjusted ORs from the probabilistic bias analysis were in the ranges of 2.63– 2.69 and 1.73– 2.83 for non-differential and differential misclassification, respectively. PAF ranges obtained were 1.36– 1.72% and 0.62– 2.01% using the non-differential bias analysis and differential bias analysis, respectively.Conclusion: After misclassification correction for smoking, the non-significant negative-adjusted association between smoking and breast cancer changed to a significant positive-adjusted association.Keywords: probabilistic bias analysis, smoking, breast cancer, Monte Carlo sensitivity analysis, population attributable fraction

Information about the epidemiological situation of the disease and its risk factors is necessary for conducting a planning program to reduce the disease. This study is conducted with the aim of evaluating the epidemiological features of bladder cancer in Iran.Methods: This is a systematic review of the published articles in both Persian and English in international and national journals during the years 2000– 2019 with key words of Iran and bladder cancer. Articles were selected from the national information database (SID, Magiran) and international databases (PubMed, Scopus, and Web of Science). Articles related to the epidemiological aspects of the disease, including incidence, prevalence, mortality, and risk factors, were evaluated.Results: The incidence rate of bladder cancer was about 1.6– 115; cumulative survival rate was 0.95, mortality rate was 0.5– 0.84 and its prevalence in the Iranian population was between 4.10% and 12.8%. The risk of developing malignancy in major risk factor groups, including smoking and opium, was 6.2 (2.04– 18.7), increases in protein and animal fat consumption were about 5- and 19-times higher than in the general population, respectively. In terms of occupational exposure, bus and heavy truck drivers were 11.3 (1.3– 92.05) more at risk than others.Conclusion: Regarding the increasing trend of this disease, changes in lifestyle to reduce risk factors can be effective in decreasing the incidence and mortality rate of this malignancy.Keywords: bladder cancer, epidemiology, Iran, incidence, risk factor

Considering the fact that knowledge on the incidence, mortality of ovarian cancer, as well as its risk factors is necessary for planning and preventing complications, this study was conducted with the aim of examining the epidemiology and risk factors of ovarian cancer in the world.Materials and methods: In order to access the articles, Medline, Web of Science Core Collection, and Scopus databases were searched from their start to the year 2018. Full-text, English observational studies that referred to various aspects of ovarian cancer were included in the study.Results: In total, 125 articles that had been published during the years 1925–2018 were entered into the study. Ovarian cancer is the seventh most common cancer among women. Increased risk factors of cancer have led to an upward trend in the incidence of cancer around the world. In 2018, 4.4% of entire cancer-related mortality among women was attributed to ovarian cancer. Although the incidence of cancer is higher among high Human Development Index (HDI) countries, the trend of mortality rate tends to be reversing. Various factors affect the occurrence of ovarian cancer, from which genetic factor are among the most important ones. Pregnancy, lactation, and oral contraceptive pills play a role in reducing the risk of this disease.Conclusion: This study provides significant evidence about ovarian cancer. Considering the heavy burden of ovarian cancer on women’s health, preventive measures as well as health education and early detection in high risk groups of women are highly recommended. Although some risk factors cannot be changed, a focus on preventable risk factors may reduce the risk of ovarian cancer. More studies are needed to explore the role of unclear risk factors in ovarian cancer occurrence.Keywords: Ovarian cancer, epidemiology, risk factor

Materials and methods: CR-NE 1% was prepared using spontaneous emulsification by soybean as oil phase; a mixture of Tween 80 and Tween 85 as surfactant; ethanol as cosurfactant and distilled water. Particle size and zeta potential of NE were assessed using Nano-ZS90 dynamic light scattering. Stability testing of NE was assessed after storage for 2 months at room temperature. In vivo experiments were carried out using 50 BALB/c mice inoculated with virulent RH strain (type I) and 50 BALB/c mice inoculated with avirulent Tehran strain (type II) of Toxoplasma gondii and treated with CR-NE (1% w/v), CR suspension (CR-S, 1% w/v), and NE without CR (NE-no CR). Results: The mean particle size and zeta potential of CR-NE included 215.66±16.8 nm and -29.46±2.65 mV, respectively, and were stable in particle size after a three freeze–thaw cycle. In acute phase experiment, the survival time of mice infected with RH strain of T. gondii and treated with CR-NE extended from 8 to 10 days postinoculation. The differences were statistically significant between the survival time of mice in CR-NE-treated group compared with negative control group (P

Abstract Background: cancer is one of the most common causes of deaths in the world. Cancer incidence and prevalence is increasing in the world. There is no clear trend is available on incidence of these cancers in Iran, therefore, this study aimed to determine the incidence of 10 common cancers among Iranian women from 2003 to 2009. Materials and Methods: A cross-sectional study was conducted by analyzing existing data. Data from a national registry of cancer cases were received. Data included the records from the cancer registry system in Iranian women during 2003 to 2009. The incidence rates were then standardized using direct method. We used Cochrane Armitage Test for linear trend by Winpepi software to determine the variation in the incidence of cancers. Results: The results show that the proportion of all cancers is rising in women as compared to all population. Breast, skin, colorectal, gastric, esophageal, thyroid, leukemia, ovary, brain and uterus were the most common cancer among Iranian women. During the years of the survey, these cancers are significantly increased. Conclusion: The results of this study showed that the incidence of cancer in women is increased. screening programs can be useful in reducing the cancers.

OBJECTIVE: COVID-19, first identified in December 2019, quickly became a global pandemic and remains a significant public health concern. Robust data is rare, especially in pregnant women. The symptoms of this disease range from mild to severe respiratory distress syndrome and mortality. The present study aimed to evaluate the factors influencing COVID-19 severity in women to be better prepared in case of a new epidemic. PATIENTS AND METHODS: This retrospective matched case-control study based on body mass index, smoke, and drug use was conducted on all women hospitalized with COVID-19 at Afzalipour Hospital in Kerman, Iran from the beginning of 2020 to 2021. In this study, 130 female patients with COVID-19 were included, with 65 patients in the case group (moderate and severe cases of COVID-19) and 65 patients in the control group (mild cases of COVID-19). The data were entered into the Stata software, and to determine the effective risk factors for the severity of COVID-19 disease, both univariate and multivariable conditional logistic regression analyses were utilized, assuming individual matching. Finally, the odds ratios (OR), along with 95% confidence intervals (CI), were estimated. RESULTS: The average age of women in the case group was 36.92 ± 7.07 years, compared to 30.12 ± 6.27 years in the control group. Among all patients, 50% were pregnant, with a mean gestational age of 30.03 weeks. Significant factors affecting disease severity included age, education, employment status, place of residence, insurance coverage, comorbidities, and pregnancy status. The highest adjusted odds ratio for severe COVID-19 was associated with comorbidities (OR = 7.8, 95% CI: 2.3-11.1), while the lowest was associated with urban residence (OR = 2.8, 95% CI: 1.02-4.5). Overall, significant predictors of severe COVID-19 included age over 30, urban residence, lack of insurance, a short duration between diagnosis and hospitalization, comorbidities, and non-pregnancy. CONCLUSIONS: The study identified several significant predictors of severe COVID-19 among women, including age over 30, urban residency, lack of insurance coverage, presence of comorbidities, and non-pregnancy, all of which were associated with a heightened risk of severe illness. Notably, comorbidities emerged as the strongest predictor. These findings underscore the critical need for targeted interventions to protect vulnerable populations. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Endometriosis means the presence of tissue similar to normal endometrium outside the uterus. Although surgical, hormonal, and analgesic treatment relieves symptoms and improves fertility, it is associated with side effects and a high recurrence rate. Alternative medicines like medicinal plants have been used for the treatment of chronic diseases. Given the global importance of endometriosis as a chronic disease affecting over 15% of all women in their fertile period, this systematic review aimed to give a comprehensive view of research on medicinal plants. MATERIALS AND METHODS: Comprehensive searches were performed on three databases, including PubMed/MEDLINE, Web of Science Core Collection (Indexes = SCI-EXPANDED, SSCI, A, and HCI Timespan), and Scopus, to identify papers published until June 2023. Keywords, such as "Endometriosis" and "Herbal Medicine", were used to search. A manual search of valid journals followed by a manual search of the references of the retrieved full-text articles was performed. All retrieved articles were imported into a database into Endnote X9. Articles that did not meet the inclusion criteria were excluded from the study, and the full texts of all the articles that met the inclusion criteria were assessed. Studies that evaluated the effects of herbal compounds on various aspects of endometriosis treatment were included in the review. RESULTS: In total, 11 studies were included in the present study. The evidence showed that in addition to safety, drugs available alongside treatments could play an effective role in improving the symptoms associated with endometriosis. In this study, the positive results of using Chinese treatments were reported in aspects such as fertility rate, pain, endometriosis recurrence rate, quality of life, sexual function, CA-125 level, and menopause symptoms. CONCLUSIONS: A wide range of preclinical and clinical studies evaluated the effectiveness and safety of medicinal plants in the treatment of endometriosis symptoms. Thus, alternative treatments for endometriosis with no or low side effects should be included in the holistic treatment of endometriosis upfront. However, there is still a need for well-designed trials to investigate standard interventions and specific and safe doses of herbal medicines. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Cervical cancer (CC) is a preventable women’s cancer. Vaccination and routine Pap smear screening have reduced cervical cancer-related mortality by 70-80% in the world. The eradication of CC depends on identifying the disease early and removing barriers to its timely detection. This review study was designed to determine diagnostic delay and factors related to delayed CC diagnosis in the world. MATERIALS AND METHODS: A comprehensive search was carried out in databases including Medline, Web of Science, Core Collection (Indexes = SCI-EXPANDED, SSCI, A & HCI Timespan), and Scopus for articles published up to December 2021. Publications were included if they reported data on the delayed CC, and factors related to diagnosis of CC in women. There was no time restriction in this review. RESULTS: In total, 45 articles were entered into the study. In studies, advanced stages of CC (IIB to IV) varied from 10.2% to 87.9% due to delayed diagnosis. A delayed CC diagnosis was reported in 4.3%-89.1% of patients. The median and mean days of delayed diagnosis were 59-210 days and 2.92-10.5 months, respectively. Factors related to delayed CC diagnosis were categorized into three components including patient, medical history, and health system delay. Patient delay included socio-demographic, husband/ partner, and knowledge. Medical history included medical issues, obstetrics, and family history. Health system delays included health facilities and levels of accessibility. CONCLUSIONS: There is an urgent need to shorten the diagnostic journey of CC patients by addressing all the components of diagnostic delay and developing strategies to modify the factors associated with these delays.

OBJECTIVE: Cervical cancer is largely preventable. Although routine Pap smear screening has reduced cervical cancer-related mortality by 70-80% in all countries and by approximately 90% in developing countries, the gynecologist is still confronted with women in advanced stages of the disease. The eradication of cervical cancer depends on identifying the disease early and removing barriers to its timely detection. Given the significant burden of cervical cancer in Asian countries, we investigated factors related to its screening in Asia. MATERIALS AND METHODS: A comprehensive search was carried out in databases such as Medline, Web of Science and Scopus for articles published until September 2020. The following keywords were used: vaginal smear, Pap smear, cervical cancer screening, barriers, obstacles, challenge, early detection, the name of each Asian country, and a combination of these words. RESULTS: Seventy-five articles were included in the study. The investigation revealed various factors related to cervical cancer screening in Asian women, including sociodemographic factors, awareness, attitudes and beliefs, perceived risk, psychological factors, self-efficacy, previous experiences, time, household, culture, fatalism, social support, access, cost, safety, insurance and health system-related factors. CONCLUSIONS: Several barriers hinder the efficacy of a screening program. Its success requires the use of educational interventions, professional and inter-professional cooperation, allocation of sufficient resources, and policymakers focusing on the elimination of barriers.

OBJECTIVE: This study was designed to investigate the incidence the premalignant and malignant cervical lesions at the 12-month follow-up investigation between cryotherapy and non-cryotherapy groups. PATIENTS AND METHODS: A prospective cohort study was performed in women with CIN 1 and PCB, who were referred to the gynecology clinic at Imam Hospital affiliated to Mazandaran University of Medical Sciences (MAZUMS), Sari, Iran, from February 2015 to November 2019. Of 232 patients, 131 consented to cryotherapy and underwent the treatment, while 101 were unwilling to undergo the treatment. After 12 months, we performed a Pap smear, a colposcopy, and a histopathological investigation of the cervix in both groups. Primary and secondary outcomes were compared between groups. The primary outcome was the comparison of incidence premalignant and malignant cervical lesions in cryotherapy and non-cryotherapy groups. The secondary outcome was a comparison of the accuracy of the Pap smear test versus colposcopy for the detection of premalignant and malignant cervical lesions in women with or without a history of cryotherapy. PATIENTS: Totally, abnormal cytological, positive colposcopic, and positive histopathological findings were reported in 41.56%, 20.26%, and 13.79 %, respectively. By histology biopsy, premalignant and malignant cervical lesions were reported in 28.24% (37/131) and 36.63% (32/101) of women in the cryotherapy and the non-cryotherapy group, respectively. This statistic did not differ significantly between groups (p = 0.78). Pap smears were abnormal in 39.7% and 44.5% of women in the cryotherapy and the non-cryotherapy group, respectively. A positive colposcopy was obtained in 27 (20.6%) and 19 (18.8%) women in the cryotherapy and the non-cryotherapy group, respectively. The diagnostic accuracy of the Pap smear test and colposcopy in detecting cervical neoplasia did not differ in women who had undergone cryotherapy and those who had not (p>0.05). CONCLUSIONS: This prospective study showed that cryotherapy is no appropriate treatment for patients with CIN1 and PCB. [ABSTRACT FROM AUTHOR]

Background and Objectives Blood transfusion is an important treatment procedure. Transfusion processes and procedures could be effective only if those involved have the adequate level of awareness about transfusion medicine. Therefore, the present study aimed to evaluate the effect of education on the knowledge of health care workers about blood products, blood administration, and complications of transfusion. Materials and Methods This quasi-experimental study was conducted on 133 hospital staff. The data were collected by the valid and reliable questionnaire. Two training workshops on the blood collection, storage, and possible side effects of blood transfusion acted as the intervention. The data were analyzed by SPSS18 software, paired t-test, and descriptive statistics. Results The knowledge of health care workers in the field of blood transfusion was inappropriate; 36.1% of the participants were poor and 63.9% average. The results showed the intervention has a significant effect on the staff knowledge (the knowledge scores before and after the intervention were 10.65 and 13.59, respectively) which was statistically significant (p=0.0001). Conclusions The results show that the improvement of education in the area of transfusion medicine would improve the awareness of hospital staff. Therefore, periodical educational programs and publication of educational pamphlets are highly recommended for the hospital staff involved in blood transfusion. [ABSTRACT FROM AUTHOR]

Background: Cervical cancer is a common cancer among women around the world. Due to the geographical differences in incidence, mortality and risk factors of cervical cancer, it is necessary to conduct different studies in different countries. This review study is aimed to investigate the most important aspects of cervical cancer in Iran. Methods: Reviewing papers without time limitation was conducted with the keywords cervical cancer, Cervix uteri cancer and Iran in their title or abstract. The databases of Medline, IranMedex, SID, ScienceDirect, Embase, Google Scholar, Web of Science, and Scopus were searched. The title and abstract of the papers were reviewed, in all, 51 full papers were reviewed. Results: Based on published studies, the incidence of cervical cancer varies between different areas of Iran. The findings of this study demonstrated that there is a relationship between marital status, marriage age, and age of first pregnancy, smoking, and consumption of oral contraceptive pills, multiple sexual partners, family history, multiparty, and cervical cancer. Conclusion: The results of this review showed that the incidence of cervical cancer in Iran is low; however, the risk factors associated with this cancer are not few, which could lead to the increase in the incidence of cervical cancer in the future.

Introduction: The purpose of the present study was to compare the effect of ENTONOX inhalation and spinal injection on the reduction of labor pain, the Apgar score of the neonates, and their side effects on new-born children and pregnant women. Material and Methods: The present clinical trial study is conducted among the pregnant women in the maternity ward of a child delivery hospital in Iran. All Participants were divided in two groups ENTONOX Inhalation and Spinal Anesthesia. Visual Analogue Scale (VAS) was implemented to measure the pain level experienced by the participants during the procedure. Moreover, the Apgar scale was used to measure the general physical health of the neonates in both groups. In addition, the participants receiving ENTONOX were asked to report the side effects they underwent during gas inhalation. However, the participants in the spinal anesthesia were checked three times. Statistical analysis was performed using SPSS version 22. Results: The findings showed that the spinal anesthesia technique was significantly more effective than gas inhalation in that it reduced as much as 3 points more than did the inhalation (P-value: 0.001). Moreover, the comparison of the mean Apgar scores showed that the mean Apgar score of the neonates of spinal anesthesia mothers was 0.36 point lower than that of the neonates in the gas inhalation group. However, this difference was not statistically significant at P- value = 0.06. Conclusions: the result of the present study indicated that spinal anesthesia was more effective than ENTONOX inhalation in reducing the labor pain.

Background: Menopausal women are widely reported to have poor sleep quality and sleep problems. It is not clear whether increases in sleep disturbance are brought about by hormone changes associated with menopause or due to psychosocial and physical problems. Method: This cross-sectional study was conducted on 600 menopausal women aged between 40 and 60 without any known severe illnesses in the city of Qaen, Iran, from April 2015 to May 2016. Data were collected by Health-Promoting Lifestyle Profile II and Pittsburgh Sleep Quality Index. Main outcome measures: This study was conducted to investigate the relationship between health-promoting lifestyle and sleep quality in Iranian postmenopausal women. Data were analyzed using an independent t-test, Mann-Whitney, Chi-square, Spearman and univariate logistic regression. Result: The univariate logistic regression suggested that the physical activity dimension of lifestyle (OR = 1.095, 95% CI: 1.035-1.158, P < 0.006), non-smoking status (OR = 0.549, 95% CI: 0.331-0.912, P < 0.021) and occupation (women who were farmer compared with housewives) (OR = 0.239, 95% CI (0.074-0.775), P < 0.017) were associated with sleep quality. Conclusion: Postmenopausal women in this study were at high risk for poor sleep quality. Poor sleep quality was associated with low levels of physical activity, smoking and being a housewife compared to being a farmer. Therefore, there is an essential need to educate women about health-promoting behaviors including daily physical activity and avoiding smoking which are associated with quality of sleep.

Background: The incidence of kidney cancer from different areas of Iran was reported. Nevertheless, there is no available systematic reviews in this regard. Therefore, the present systematic review carried out to estimate the incidence rate of kidney cancer among Iranian people. Method: This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) in September 2017. A search was concluded using Medline/ PubMed, Scopus, ScienceDirect, and Google scholar for international papers and four national databases (Scientific Information Database, MagIran, IranMedex, and IranDoc) for Persian papers. The incidence rate of kidney cancer was calculated using random effect model. Result: An aggregate of 159 papers were retrieved in the primary search of the databases. Further screening and advanced refinement of the retrieved studies produced 15 studies totally. The age-standardized rate (ASR) of kidney cancer was 1.94, 95% CI (1.62-2.55) and 1.36, 95 % CI (1.09-1.62) in males and females, respectively. Conclusion: In comparison to other parts of the world, the incidence of kidney cancer was lower in Iran. Afterwards, further studies are necessary to outline the exact incidence rate and the trend of kidney cancer in Iran.

Background: This study aimed to investigate the relationship between Body Mass Index (BMI) and quality of life in primary school students in Tehran. Method: In this cross-sectional study 829 primary school children and their parents participated. Healthrelated quality of life (HROOL) was evaluated with the Persian version of Pediatric Quality of Life Inventory (PedsQL™4.0) questionnaire. According to objective measures of height and weight, children BMI computed, and adapted for age and gender. For data analysis we used Pearson correlation test, Independentsample t-test and ANOVA using SPSS version 18. Results: Mean of children self-reported HRQOL total score was 82.05 ± 12.04 and mean of parent proxyreported HRQOL total score was 81.66 ± 12.81. Based on HRQOL subscale scores, social functioning was the highest subscale score of HRQOL (84.67 ± 15.07) and the emotional subscale score was the lowest (77.79 ± 17.26). Lower HRQOL scores were significantly correlated with Higher BMI and normal weight children had significantly higher HRQOL total score than obese children (P < 0.05). The difference between normal weight and overweight children in HRQOL total scores were not significant. Same results were obtained from parent proxy-reports and a good harmony between children self-report and parent proxy-report of HRQOL was perceived. Conclusion: This study showed that HRQOL of obese children were at the lower level in comparison to normal weight and overweight children. At further interventional studies these outcomes can be very important for improving quality of life in obese children.

Objective: This study describes the 2010-2019 trend of cervical cancer (CC) in women over 55 by socio-demographic index (SDI) and geographical regions., Methods: We obtained data on CC annually from 2010 to 2019 from the 2019 Global Burden of Disease Study (GBD) to analyze the incidence, death and prevalence rates, and disability-adjusted life years (DALYs) associated with CC across different parameters such as global trend, age groups, SDI, continents, World Bank Regions, World Health Organization (WHO) regions, GBD regions, and National and territorial division. This analysis covers data from 204 countries and territories from 1990 to 2019., Results: There were 236,228 CC incidence cases worldwide in 2019, which is a 1.27-fold increase from 2010. Global CC deaths also increased to 169,304 cases in 2019, reflecting a 1.24-fold increase. CC prevalence increased to 769,925 cases in 2019, representing a 1.4-fold rise. The number of CC DALYs globally increased to 3,835,979 cases in 2019, reflecting a 1.24-fold increase. Incidence, death, prevalence, and DALY numbers of CC increased across all age groups females in the 65-69 years age group experienced the highest increase. Middle SDI countries had the highest incidence, death, prevalence, and DALY numbers, while low SDI countries showed increasing trends. Asia exhibited the highest incidence, death, prevalence, and DALY numbers of CC. Upper middle-income countries had the highest incidence, death, prevalence, and DALY numbers, with the highest decreases in these rates except the prevalence rate. The Western Pacific Region showed the highest incidence, death, prevalence, and DALY numbers, with declining rate trends. The Republic of Kiribati showed the highest incidence, death, prevalence, and DALY numbers., Conclusion: Based on the study results, it is clear that although the global trend of epidemiological indicators of CC is decreasing, the largest proportion of the decreasing trend is related to developing countries. But in regions of Africa and Asia that have a lower level of development, sometimes these indicators show upward trends, which shows the worsening of the problem in these regions and the need for serious policies and plans to implement comprehensive vaccination, screening, and promotion interventions. People's awareness is necessary in the field of better disease control., Competing Interests: All authors declare that they have no conflict of interest., (© 2024 The Author(s).

Background/Objectives: Hysteroscopy has been used as both a diagnostic and therapeutic tool for intrauterine pathologies under direct visualization. However, this procedure may be associated with an increased risk of complications during entry, which can be reduced by cervical ripening before the operation. The efficacy of misoprostol in this context is influenced by factors such as estrogen levels, parity, and the mode of previous deliveries. This study aimed to assess the efficacy and safety of misoprostol in women with a challenging cervix while mitigating the influence of confounding variables. Methods: Three electronic databases, namely PubMed, Scopus, and ISI Web of Science, were searched until 14 May 2024. Randomized controlled trials focusing on postmenopausal patients, nulliparous women, and multiparous women with no prior history of vaginal delivery, undergoing hysteroscopy were included. The cervical width, time needed for cervical dilation, and the need for additional dilatation alongside the complications and adverse effects from all included studies were collected and analyzed using R (version 4.2.3). Results: Seven studies on premenopausal women and three on postmenopausal women were included. In premenopausal women, misoprostol significantly increased cervical width compared to placebo (SMD = 2.2, 95% CI 0.9 to 3.4) and reduced the need for additional cervical dilatation (OR = 0.36, 95% CI 0.17 to 0.74). No significant difference was found in the time required for cervical dilation between misoprostol and placebo groups. In postmenopausal women, misoprostol did not significantly affect cervical width compared to placebo (SMD = -0.55, 95% CI -1.3 to 0.21). Conclusions: Misoprostol is beneficial for cervical dilation in premenopausal women without a prior history of vaginal delivery but less effective in postmenopausal patients. While associated with postoperative risks, it reduces hysteroscopy-related complications. Future research should address discrepancies by controlling the confounding variables like menopausal status, parity, and mode of delivery to enhance the understanding of misoprostol's effects and pinpoint the specific patient populations that would derive the greatest benefits from its use.

Objective: The most effective methods and entry sites for laparoscopic surgery remain a subject of ongoing investigation and discussion. The purpose of the study was to analyze and compare three umbilical entry sites for intraperitoneal access using the direct trocar insertion technique., Material and Methods: A randomized pilot study was conducted between March 2021 and January 2023, involving women eligible for laparoscopic gynecological surgery. The women were allocated to one of three equally sized groups based on trocar entry points: subumbilical, supraumbilical, or umbilical. Success and failure rates of trocar entry, factors influencing success or failure, and early and late complications were systematically evaluated and compared across groups., Results: A total of 243 patients, with a mean age of 32.93±8.33 years, were included in three groups of 81 each. Trocar entry success rates were 97.5%, 89.2%, and 89.5% in the supraumbilical, umbilical, and subumbilical groups, respectively (p>0.05). Failed trocar entry was significantly associated with age, gravidity, body mass index (BMI), waist circumference, hip circumference, and abdominal subcutaneous fat thickness (p<0.001). Regression analysis revealed that, in the subumbilical group, higher gravidity [odds ratios (OR): 0.390, 95% confidence interval (CI): 0.174-0.872, p=0.022) and greater abdominal subcutaneous fat thickness (OR: 0.090, 95% CI: 0.019-0.431, p=0.03) were associated with lower odds of successful trocar entry. In contrast, in the umbilical group, a higher waist circumference was associated with lower odds of successful trocar entry (OR: 0.673, 95% CI: 0.494-0.918, p=0.012). None of the covariates were significant in the supraumbilical group., Conclusion: The study highlighted the importance of selecting the appropriate trocar entry site in laparoscopic gynecological surgery. Surgeons should consider factors such as age, gravidity, BMI, waist circumference, hip circumference, and abdominal subcutaneous fat thickness, as these factors significantly influence the success of trocar entry., Competing Interests: Conflict of Interest: No conflict of interest is declared by the authors.

Background : Despite the availability of treatments such as surgery and hormonal therapy, women with endometriosis often endure chronic problems. This review aims to evaluate the effectiveness and safety of neuropelveology. Methods : In a systematic review with a meta-analysis, we searched three electronic databases: MEDLINE (PubMed), Scopus, Embase, and Web of Science (WOS). The search was conducted in January 2024 with no date or language restrictions using a carefully curated set of keywords. We conducted a comprehensive review, including all observational and clinical trials reporting data on neuropelveology approaches in the management of endometriosis, irrespective of geographical location. The studies included in our review were required to be published in peer-reviewed journals and be available in any language, with at least an abstract in English. The data of all included studies were summarized in excel (version 19) and were analyzed by Comprehensive Meta-analysis v3.3 (Biostat) and STATA (version 17). A multilevel meta-analysis was performed on studies with two arms (intervention and control) to evaluate the efficacy of neuropelveology in managing women with endometriosis. Results : After screening 476 records, 30 studies, published from 1952 to 2021, were included in this review, each employing various methodologies. The studies were divided into the following three categories: (a) efficacy of neurectomy or nerve resection ( n = 20), (b) efficacy of neurolysis (nerve blocks) ( n = 4), and (c) efficacy of neuromodulation ( n = 6) in the management of endometriosis. Among the studies evaluating the efficacy of neurectomy or nerve resection, 10 studies (with 18 group comparisons) were included in the random-effects meta-analysis. Treatment success (not occurrence of pain) was higher with neurectomy vs. controls (RR = 0.497, 95% CI = 0.236 to 1.04, p = 0.06 (for experimental studies) and RR = 0.248, 95% CI = 0.14 to 0.43, p < 0.001 (for observational studies)), representing a 50% and 75.2% risk reduction in the recurrence of pain in experimental and observational studies, respectively. Similarly, neurolysis, particularly superior hypogastric plexus blocks and uterine nerve ethanol neurolysis, demonstrated encouraging outcomes in pain reduction and an improved quality of life for women with endometriosis. The efficacy of neuromodulation in managing endometriosis symptoms appears promising but requires further investigation. Conclusions : In conclusion, neuropelveology approaches, such as neurectomy, neurolysis, and neuromodulation, offer significant potential for pain reduction in endometriosis patients, albeit with risks of complications and high recurrence rates, necessitating careful patient selection and long-term monitoring.

Ovarian cancer is among the most lethal gynecological cancers, primarily due to the lack of specific symptoms leading to an advanced-stage diagnosis and resistance to chemotherapy. Drug resistance (DR) poses the most significant challenge in treating patients with existing drugs. The Food and Drug Administration (FDA) has recently approved three new therapeutic drugs, including two poly (ADP-ribose) polymerase (PARP) inhibitors (olaparib and niraparib) and one vascular endothelial growth factor (VEGF) inhibitor (bevacizumab) for maintenance therapy. However, resistance to these new drugs has emerged. Therefore, understanding the mechanisms of DR and exploring new approaches to overcome them is crucial for effective management. In this review, we summarize the major molecular mechanisms of DR and discuss novel strategies to combat DR., Competing Interests: The authors declare that they have no conflicts of interest to report regarding the present study., (© 2024 Alemzadeh et al.)

Background: The COVID-19 pandemic highlighted the need to study oral fungal carriage and its potential impact. In oral fungal environments, factors like changes in respiratory epithelium, increased pathogen attachment, local inflammation, and virulence factors could influence COVID-19 severity. The authors conducted a study to explore oral fungal carriage in COVID-19 patients and compare it to a healthy control group., Methods: The authors executed a case-control investigation including 144 COVID-19 patients and an equivalent number of 144 healthy controls. The matching criteria encompassed age, sex, body mass index, and the history of antibiotic and antiviral medication intake. This research was performed over a span of 12 months from May 2021 to May 2022. The mouth area was sampled with a cotton-tipped swab. Subsequently, all the samples underwent fungal culture and PCR-sequencing procedures., Results: In COVID-19 patients, oral fungal carriage was three times higher compared to healthy controls. Candida was the exclusive genus found in both groups, with Candida albicans being the most frequently isolated species (90.79%). Among COVID-19 patients, Candida species showed significantly higher esterase, proteinase, and hemolysin activity compared to healthy individuals. Both groups exhibited elevated levels of C. albicans virulence factors compared to non-albicans species., Conclusions: It is crucial to understand the way that virulence factors of oral fungal carriage act in COVID-19 patients in order to come up with novel antifungal medications, identify the contributing factors to drug resistance, and manage clinical outcomes., Competing Interests: The authors have no conflict of interest to declare.Sponsorships or competing interests that may be relevant to content are disclosed at the end of this article., (Copyright © 2024 The Author(s).

Background: People with disabilities (PWD) typically face a range of obstacles when accessing healthcare, particularly when compared with the general population. This challenge becomes more pronounced for PWDs in lower socioeconomic groups. This study aimed to assess the socioeconomic-related disparity in financial access to rehabilitation services among Iranian PWDS., Methods: A total of 766 Iranian PWDs aged ≥18 years participated in this cross-sectional study. We employed the concentration index (C) to estimate socioeconomic inequality in accessing rehabilitation services., Results: In this study, 766 Iranian adults aged 18 to 70 took part, with a mean age of 36.50 (SD, ±10.02) years. The findings revealed that 72.15% (n = 469) of participants had to borrow money to cover the costs of rehabilitation services. The concentration index (C = -0.228, P = 0.004) demonstrated a notable concentration of inadequate financial access to rehabilitation services among individuals with lower socioeconomic status (SES). Decomposition analysis identified the wealth index as the primary contributor to the observed socioeconomic disparities, accounting for 309.48%., Conclusion: Our findings show that socioeconomic inequalities disproportionately impact PWDs in lower socioeconomic groups. It is recommended that efforts be made to enhance the national capacity for monitoring the financial protection of PWDs and to develop equitable mechanisms that promote prepayment and risk pooling, thus reducing reliance on out-of-pocket payments at the time of service utilization., Competing Interests: The authors declare that they have no competing interests., (© 2024 Iran University of Medical Sciences.)

Objectives: This study aimed to assess the severity and related factors of symptomatic COVID-19 in end-stage renal disease (ESRD) patients from several centers in Eastern Iran., Methods: In this retrospective cohort study, after obtaining ethical approval, 410 patients diagnosed with COVID-19 were included for analysis. Patients were categorized into two groups based on their dialysis status: the dialysis group (ESRD patients undergoing hemodialysis) and the non-dialysis group (those without chronic dialysis). Demographic information, clinical symptoms, laboratory tests at admission, length of hospitalization, ICU admission, need for mechanical ventilation, and mortality data were extracted from their medical records and entered into researcher-developed checklists., Results: In this multicenter study, 104 dialysis patients with a mean age of 64.81 ± 16.04 were compared to 316 non-dialysis patients with a mean age of 60.92 ± 17.89. Patients were similar in terms of age and gender, but a higher percentage of the dialysis group was aged over 65 years (p = .008). Altered consciousness, dyspnea, headache, myalgia, anorexia, and cough were statistically significantly more common in the dialysis group when evaluating clinical symptoms (p < .05). The dialysis group had significantly higher levels of white blood cell (WBC), potassium, calcium, urea, creatinine, blood pH, INR, ALT, ESR, and CRP, and lower levels of red blood cell, Hb, platelets, sodium, and LDH compared to the non-dialysis group. Profoundly altered consciousness was more common among deceased patients (p < .001), and this group had higher WBC counts, urea levels, AST, ALT (p < .05), and lower blood pH (p = .001)., Conclusion: Based on the results of this study, it is plausible to suggest a hypothesis of greater severity and worse prognosis of COVID-19 in ESRD patients. Underlying comorbidities, such as liver disorders or more severe clinical symptoms like altered consciousness, may also be indicative of a worse prognosis in dialysis patients with COVID-19., (© 2024 The Authors.

Aim: Domestic violence is an important public health and human rights problem. In most countries of the world, including Iran, the COVID-19 pandemic made quarantine necessary to reduce the disease transmission rate. Therefore, due to the spread of the COVID-19 disease and the emergence of mandatory quarantine conditions, the present study was conducted to determine the prevalence of domestic violence against women during the COVID-19 pandemic in Iran., Methods: In this cross-sectional study, which was done in 2020, 240 married women were investigated. Due to the COVID-19 pandemic, data collection was performed through virtual networks using standard questionnaires. Data were analyzed using SPSS. Descriptive statistics (relative frequencies, mean, and standard deviation) were used to determine the extent of violence. Independent t-test and Chi-square were used to analyze the data of the relation between the types of violence with independent variables. Also, the data were analyzed using the logistic regression model., Results: In this study, 240 married women with a mean age of 36.27 were studied. The highest frequency was related to social violence (56.3%), and the lowest was related to financial and verbal violence (11.7%). In addition, a significant relationship was observed between sexual violence and age (p-value < 0.05). A significant relationship was also observed between social violence and education [(OR = 1.99)] Jobs [(OR = 2.4, CI = 95%, 1.30-4.4), quarantine duration [(OR = 1.94, CI = 95%, 0.98-3.7)] and underlying diseases [OR = 1.90]., Conclusion: The high prevalence of domestic violence against women during quarantine indicates the poor health of women in society. Therefore, the roots of violence against women and methods to reduce this problem should be sought. Therefore, identification of subjects at risk and raising women's knowledge may be useful for the prevention of domestic violence and its physical and psychological complications., (© 2023 The Authors.

Objective: Dental plaque bacteria, including Streptococcus mutans ( SM ), play a role in the pathogenesis of the dental caries. There are conflicting results regarding the association of salivary SM level and dental caries susceptibility. Our aim was to compare salivary SM levels in colony-forming units (CFU) between children with active caries and caries-free children in Birjand, Iran., Methods: This case-control study included 61 six-year-old children referred to health centers in Birjand city, Iran, in 2022. The children were divided into two groups: case (dmft/DMFT>0 with active caries) (including 31 children) and control (dmft/DMFT = 0 [caries-free]) (including 30 children). Demographic information and dental history were recorded. Oral examinations were also performed by the dentist. Unstimulated saliva samples were collected from children. The number of salivary SM colonies was determined using the microbial culture and confirmed using the polymerase chain reaction (PCR). The data were analyzed using Chi-square and T-tests at a significance level of p < 0.05., Results: The mean number of SM colonies was 126.24 ± 92.78 CFU/ml and 92.38 ± 75.34 CFU/ml in case and control groups, respectively. No significant difference was found in salivary SM levels between case and control groups (P = 0.125). No significant association was observed between caries experience with gender (P = 0.363), type of school (public/private) (P = 0.296), receiving oral health education (P = 0.072) and frequency of tooth brushing (P = 0.935). The mean gingival index (P = 0.001) and plaque index (P = 0.025) in case group were significantly higher than control group., Conclusion: There is no significant difference in salivary SM levels between caries-active and caries-free children in Birjandi children., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.

Background: Chronic hepatitis B (CHB) virus is the most common risk factor for developing liver malignancy. Autophagy is an essential element in human cell maintenance. Several studies have demonstrated that autophagy plays a vital role in liver cancer at different stages. In this systematic review, we intend to investigate the role of polymorphism and mutations of autophagy-related genes (ATGs) in the pathogenesis and carcinogenesis of the hepatitis B virus (HBV)., Materials and Methods: The search was conducted in online databases (Web of Science, PubMed, and Scopus) using Viruses, Infections, Polymorphism, Autophagy, and ATG. The study was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria., Results: The primary search results led to 422 studies. By screening and eligibility evaluation, only four studies were relevant. The most important polymorphisms in hepatocellular carcinoma were rs2241880 in ATG16L1, rs77859116, rs510432, and rs548234 in ATG5. Furthermore, some polymorphisms are associated with an increased risk of HBV infection including, rs2241880 in ATG16L1 and rs6568431 in ATG5., Conclusion: The current study highlights the importance of rs2241880 in ATG16L1 and rs77859116, rs510432, and rs548234 in ATG5 for HBV-induced HCC. Additionally, some mutations in ATG16L1 and ATG5 were important in risk of HBV infection. The study highlights the gap of knowledge in the field of ATG polymorphisms in HBV infection and HBV-induced HCC., (© 2024 The Authors.

Background: Cancer poses an escalating public health challenge, necessitating a comprehensive understanding of cancer incidence to formulate effective control strategies., Aims: This study aims to present a comprehensive overview of cancer incidence in Iran, utilizing data from the Iranian National Population-based Cancer Registry (INPCR) for the year 2016., Methods: The study employed INPCR data to compute crude and age-standardized incidence rates (ASR) per 100 000 for the most common cancers among men and women across Iran's 31 provinces. Data analysis utilized Excel (2019) and STATA 14., Results: In 2016, 124 833 new cancer cases were registered, with 65 495 (52.90%) occurring in men and 58 312 (47.10%) in women. ASRs for all cancers in the total population were 177.48, with specific rates for men and women at 192.96 and 162.33, respectively. The five most common cancers in men were prostate (23.25), stomach (21.56), colon (19.30), bladder (16.20), and lung (13.15). Among women, the leading cancers were breast (40.60), colon (14.64), thyroid (10.84), stomach (10.25), and lung (5.63). West Azarbaijan had the highest incidence among men, while Yazd topped the list for women. Age-specific incidence rates revealed peaks in the 67-74 age group for men and the 40-50 age group for women., Conclusion: This study affirms that while Iran exhibits a lower cancer incidence compared to global averages, there has been a temporal increase. Disparities in ASR exist across sexes and provinces, with shifts in the ranking of common cancers by sex compared to previous reports., (© 2023 The Authors.

Background and Aim: Endometrial cancer (EC) is the sixth most common cancer among women worldwide. Since global studies are based on awareness of the incidence trend, mortality, geographical diversity, and level of social development and income of countries, this study was conducted to investigate the trend of uterine cancer (UC) in the world in 2019., Methods: Age-standardized rates (ASR) of incidence, deaths, prevalence, and disability-adjusted life years (DALYs) of UC, as well as targeted risk factors, were extracted from the Global Burden of Disease (GBD) online database 2019. Pearson correlation coefficient and SPSS 16 were used to calculate the correlation between risk factors and ASR of epidemiological indicators. Statistical significance was considered as p  < 0.05., Results: In 2019, the age-specific incidence and death rate of UC was peaking at 60-64 and 65-69 years, respectively. The highest age-standardized incidence rate per 100,000 people for UC has been reported in the Northern Mariana Islands, high sociodemographic index (SDI) countries, World Bank High-Income category, Europe continent and among World Health Organization (WHO) regions were found in the European Region. The highest age-standardized death rate per 100,000 people for UC has been reported in Grenada, high SDI countries, the World Bank High-Income category, Europe continent, and among WHO regions found in the European Region. In 2019, the age-standardized DALYs rate was 53.54 per 100,000 inhabitants, of which 48.49 cases were related to years of life lost (YLLs) and 5.05 cases were related to years lived with disability., Conclusion: According to GBD-2019, the highest incidence, mortality, and DALY of UC are in Europe. The evidence and traces of diversity can be seen in the inequalities of UC. Race, ethnicity, economic status, level of education and awareness, co-morbidities, access, grade, and histological type of tumor are the most important causes of this inequality., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.
