RESUMEN
Background: Pregnant women have poor knowledge of oral hygiene during pregnancy. One problem with the follow-up of dental caries in this group is zero accumulation in the decayed, missing, and filled teeth (DMFT) index, for which some models must be used to achieve valid results. The studied population may be heterogeneous in longitudinal studies, leading to biased estimates. We aimed to assess the impact of oral health education on dental caries in pregnant women using a suitable model in a longitudinal experimental study with heterogeneous random effects. Materials and Methods: This longitudinal, experimental research was carried out on pregnant women who visited medical centers in Tehran. The educational group (236 cases) received education for three sessions. The control group (200 cases) received only standard training. The DMFT index assessed oral and dental health at baseline, 6 months, and 24 months after delivery. The Chi-square test was used for comparing nominal variables and the Mann-Whitney U test for ordinal variables. The zero-inflated Poisson (ZIP) model was applied under heterogeneous and homogeneous random effects using R 4.2.1, SPSS 26, and SAS 9.4. The level of significance was set at 0.05. Results: Data from 436 women aged 15 years and older were analyzed. Zero accumulation in the DMFT was mainly related to the filled teeth (51%). The heterogeneous ZIP model fitted better to the data. On average, the intervention group exhibited a higher rate of change in filled teeth over time than the control group (P = 0.021). Conclusion: The proposed ZIP model is a suitable model for predicting filled teeth in pregnant women. An educational intervention during pregnancy can improve oral health in the long-term follow-up.
RESUMEN
BACKGROUND: The relationship between the dietary insulin index (DII) and the disease's risk is unknown, despite the fact that hyperinsulinemia is presumed to contribute to osteoporosis. The insulin response of various diets determines the DII. This study aimed to investigate the connection between postmenopausal Iranian women's adherence to a diet with a higher insulinemic potential and osteoporosis. METHODS: A total of 380 postmenopausal women were included in the current case-control study. A 168-item food frequency questionnaire (FFQ) with established validity and reliability was used to evaluate individuals' daily calorie intake. The standard formula was employed to determine the dietary insulin load of each product. Subsequently, the calculation of DII was performed by dividing the dietary insulin load by the total energy consumed for each individual. In order to investigate the relationship between osteoporosis and DII, logistic regression was implemented. RESULTS: The results of the current study demonstrated a substantial inverse relationship between osteoporosis and the DII, even after accounting for confounding variables (OR = 0.927; 95% CI = 0.888-0.967). The mean scores of DII (P < 0.001) was significantly higher in control group (36.82 ± 8.98) compared to the case group (33.53 ± 6.28). CONCLUSIONS: Our findings suggest that keeping a diet high in insulin index and low in foods that are insulinogenic may improve bone mass density. Consequently, it may be essential for postmenopausal women to consume nutrients that stimulate insulin production in order to prevent osteoporosis.

BACKGROUND: Men experiencing infertility encounter numerous problems at the individual, family, and social levels as well as quality of life (QOL). This study was designed to investigate the QOL of men experiencing infertility through a systematic review. MATERIALS AND METHODS: This systematic review was conducted without any time limitation (Retrieval date: July 1, 2023) in international databases such as Scopus, Web of Science, PubMed, and Google Scholar. The search was performed by two reviewers separately using keywords such as QOL, infertility, and men. Studies were selected based on inclusion and exclusion criteria. The quality of the articles were evaluated based on the Newcastle-Ottawa Scale. In the initial search, 308 studies were reviewed, and after removing duplicates and checking the title and abstract, the full text of 87 studies were evaluated. RESULTS: Finally, 24 studies were included in the final review based on the research objectives. Based on the results, men's QOL scores in different studies varied from 55.15 ± 13.52 to 91.45 ± 13.66%. Of the total reviewed articles, the lowest and highest scores were related to mental health problems and physical dimensions, respectively. CONCLUSION: The reported findings vary across various studies conducted in different countries. Analysis of the factors affecting these differences is necessary, and it is recommended to design a standard tool for assessing the quality of life of infertile men. Given the importance of the QOL in men experiencing infertility, it is crucial to consider it in the health system. Moreover, a plan should be designed, implemented and evaluated according to each country's contex to improve the quality of life of infertile men.

BACKGROUND: Today, cardiovascular disease (CVD) is the most important cause of death around the world. In this study, our main aim was to predict CVD using some of the most important indicators of this disease and present a tree-based statistical framework for detecting CVD patients according to these indicators. METHODS: We used data from the baseline phase of the Fasa Cohort Study (FACS). The outcome variable was the presence of CVD. The ordinary Tree and generalized linear mixed models (GLMM) were fitted to the data and their predictive power for detecting CVD was compared with the obtained results from the GLMM tree. Statistical analysis was performed using the RStudio software. RESULTS: Data of 9499 participants aged 35â70 years were analyzed. The results of the multivariable mixed-effects logistic regression model revealed that participants' age, total cholesterol, marital status, smoking status, glucose, history of cardiac disease or myocardial infarction (MI) in first- and second-degree relatives, and presence of other diseases (like hypertension, depression, chronic headaches, and thyroid disease) were significantly related to the presence of CVD (P<0.05). Fitting the ordinary tree, GLMM, and GLMM tree resulted in area under the curve (AUC) values of 0.58 (0.56, 0.61), 0.81 (0.77, 0.84), and 0.80 (0.76, 0.83), respectively, among the study population. In addition, the tree model had the best specificity at 81% but the lowest sensitivity at 65% compared to the other models. CONCLUSION: Given the superior performance of the GLMM tree compared with the standard tree and the lack of significant difference with the GLMM, using this model is suggested due to its simpler interpretation and fewer assumptions. Using updated statistical models for more accurate CVD prediction can result in more precise frameworks to aid in proactive patient detection planning.

Background & Aims: Education and counseling during marriage is an opportunity to raise some issues needed by couples on the verge of marriage. This study was conducted with the aim of improving reproductive and sexual health literacy of couples on the verge of marriage. Methods: This study was a mixed-methods participatory action research conducted based on the Find, Organize, Clarify, Understand, Select-Plan, Do, Check, Act (FOCUS-PDCA) model in nine steps during 2019-2020 in the city of Bandar Abbas. The Reproductive Health Literacy Scale and the Service Quality (SERVQUAL) Questionnaire were used to evaluate the interventions. Data were analyzed by SPSS version 26. A significance level of less than 0.05 was considered. Results: The mean age of women and men participating in the quantitative part of the study was 21 ± 5 and 25.84 ± 3.9 years, respectively, which was similar to their counterparts in this part of the study, and the difference in the mean scores of reproductive health literacy before and after the changes in the program showed a significant difference (p > 0.001). The study results showed that, except for the understanding dimension, most participants were at an insufficient level in other dimensions of reproductive health literacy. The result of measuring the satisfaction of service recipients indicated good satisfaction in the two dimensions of warranty and accountability, and there was a gap in empathy, assurance, and tangibility dimensions, which the biggest gap was related to the empathy dimension. Conclusion: The changes made in improving the reproductive health literacy of couples were effective, which can be taken into consideration based on the added items in the current program of providing educational services in marriage preparation classes for couples.
RESUMEN
BACKGROUND: Food and nutrition insecurity is a major health issue in developing countries. Homestead food production (HFP) programs are strategies for improving food and nutrition security of a country. Iran implemented a HFP program entitled "Nutrition Improvement of Rural and Nomadic Women" in its villages for a five-year period from 2017. The current study assessed the outcomes of this mentioned program and its determinants among rural women in Tehran province. METHODS: The population of this cross-sectional study comprised a group covered by the program (n = 143) and a non-covered group (n = 160). The participants were selected randomly from 32 villages of five counties in Tehran province. Data was collected using five questionnaires: (1) General information, (2) Women's empowerment, (3) Nutritional knowledge, (4) Dietary diversity, and (5) Household Food Insecurity Access Scale (HFIAS). Data was analyzed using the IBM SPSS version 21 and the IBM Amos SPSS version 22 software. RESULTS: The results of the study showed no significant improvement in the expected indicators, such as frequency of home gardening, nutritional knowledge, dietary diversity, women's empowerment, and household food insecurity status among women covered by the program (p > 0.05). The structural equation modelling (SEM) results indicated that women's empowerment from the dimension of decision-making power (r = 0.151) and nutritional knowledge (r = 0.135) were the significant positive predictors of dietary diversity (p < 0.05), while household food insecurity predicted it negatively (r=-0.138) (p < 0.05). CONCLUSION: Because the current evaluated program has not been able to improve the expected indicators, modification of the program implementation may be needed, such as: addressing the probable barriers and challenges and strengthening the facilities in the covered villages. The current study presents a model of the dietary diversity predictors for consideration in redesigning or enhancing the program.

Background: Osteoporosis, a prevalent bone malady, is prevalent in Iran. Several studies have represented the role of dietary antioxidants on osteoporosis. The dietary antioxidant index (DAI) is a valid and reliable index, which indicates a comprehensive view of dietary antioxidant capacity. This study aimed to survey the relationship of the DAI with the risk of osteoporosis in postmenopausal women in Iran. This research aimed to examine the association between the DAI and the risk of osteoporosis among postmenopausal women in Iran. Materials and Methods: In this case-control study, 440 postmenopausal women (220 cases and 220 controls) were enrolled. The dietary intake of contributors was evaluated using a 147-item food frequency questionnaire. To estimate the DAI, the amount of six antioxidant micronutrients such as Vitamins A, C, and E, selenium, manganese, and zinc was standardized. Then, the DAI was estimated by collecting the standardized consumption of these antioxidant micronutrients. Results: Our findings represented the participants in the first (crude odds ratio [OR] = 1.79, 95% confidence interval [CI]: 1.13-2.85, P = 0.013) and second (crude OR = 1.60, 95% CI: 1.01-2.55, P = 0.043) tertiles of the DAI scores had significantly higher odds of osteoporosis compared to those in the third one; while after modifying for confounding factors, this significant reverse relationship was observed just between women in the first and third tertiles of the DAI scores (adjusted OR = 1.90, 95% CI: 1.34-3.18, P = 0.015). Conclusion: The consequence of this study suggested that adherence to a diet rich in antioxidant compounds may have protective effects against osteoporosis.
RESUMEN
Objectives: The focused question of this systematic review was "does hyaluronic acid (HA) injection in areas of interdental papillary deficiency reduce black triangles?" Materials and Methods: A systematic literature search was performed to find clinical studies on human patients with a minimum of 6-month follow-up, published in English from 2005 to May 2020. There were two outcome variables: black triangle area (BTA) change after treatment at different measurement time points compared with baseline, and patient reported outcome measures (PROMs), when available. Results: Of eight eligible articles (2 randomized clinical trials (RCTs) and 6 non-randomized, non-placebo controlled clinical studies), seven reported that HA injections had a positive impact on reduction of BTA and subsequent papillary augmentation. Six studies were included in meta-analysis and showed that the intervention led to a pooled reduction percentage of 57.7% in BTA after 6 months. Although there were clinical diversities between the studies, all the studies applied the same concentration of HA (approximately 2%), 2-3 mm apical to the papilla tip in several intervals. Some degrees of relapse were reported in some studies. Conclusion: Within the limits of this study, this systematic review and meta-analysis showed that HA injection can serve as an efficient minimally-invasive treatment for small interdental papillary deficiencies. It is essential to conduct further randomized clinical studies with prolonged follow-ups in order to support this conclusion.
RESUMEN
Background: Colorectal cancer is a major health problem both in developing and developed countries. This cancer is among the top three commonly diagnosed cancers in males and females. In this context, assessing the Incidence, Prevalence and Mortality Rate trend of this cancer is of great importance. Methods: We used the data from the GBD 2017 study to assess the global trend of 3 important indicators of colorectal cancer burden and to examine the relationship between trends of these indicators with Human Development Index (HDI). We used the multivariate mixed effects modeling framework with time and HDI as the covariates. Results: Trend analysis of colorectal cancer burden indicators showed a rather steady trend for mortality rate, while it revealed increasing slopes for both the incidence and prevalence rates. In addition, our findings showed a direct relationship between prevalence and incidence rates of this cancer and HDI level and indirect association between mortality rate and level of HDI. Conclusion: There were significant changes in indicators of colorectal cancer during the study period. The inverse relationship between mortality due to this cancer and socio-economic status of the countries indicated an urgent need for screening the patients and promoting the level of care in countries with lower levels of HDI.
RESUMEN
AIMS: Without any doubt, vaccination was the best choice for Coronavirus disease 2019 (COVID-19) pandemic control. According to the American Society of Clinical Oncology (ASCO) and European Society for Medical Oncology (ESMO), people with cancer or a history of cancer have a higher risk of dying from Covid-19 than ordinary people; hence, they should be considered a high-priority group for vaccination. On the other hand, the effect of the Covid-19 vaccination on cancer is not transparent enough. This study is one of the first in vivo studies that try to show the impact of Sinopharm (S) and AstraZeneca (A) vaccines on breast cancer, the most common cancer among women worldwide. MATERIALS AND METHODS: Vaccination was performed with one and two doses of Sinopharm (S1/S2) or AstraZeneca (A1/A2) on the 4T1 triple-negative breast cancer (TNBC) mice model. The tumor size and body weight of mice were monitored every two days. After one month, mice were euthanized, and the existence of Tumor-infiltrating lymphocytes (TILs) and expression of the important markers in the tumor site was assessed. Metastasis in the vital organs was also investigated. KEY FINDINGS: Strikingly, all of the vaccinated mice showed a decrease in tumor size and this decrease was highest after two vaccinations. Moreover, we observed more TILs in the tumor after vaccination. Vaccinated mice demonstrated a decrease in the expression of tumor markers (VEGF, Ki-67, MMP-2/9), CD4/CD8 ratio, and metastasis to the vital organs. SIGNIFICANCE: Our results strongly suggest that COVID-19 vaccinations decrease tumor growth and metastasis.

BACKGROUND: Infertility is a major challenge in the life of women which affects their quality of life. Infertile women's quality of life is a relatively new field of research that has recently been considered by health researchers. However, there has been no standard tool for measuring different aspects of infertile women's quality of life with female factors, and general and specific tools of infertile couples have been used to assess their quality of life. This study, thus, aimed to analyze different aspects of the quality of life of infertile women. METHODS: This descriptive cross-sectional study was conducted on 320 infertile women referred to a teaching hospital affiliated with Mazandaran University of Medical Sciences and private infertility treatment centers in Sari, Iran. Demographic and fertility characteristics and the quality of life questionnaire for infertile women questionnaire (a 25-item tool was designed which measured 7 factors of psychological effects, sexual life with infertility family and social effects, infertility-related concerns, physical effects, adaptive approaches and factors preventing infertility adaptation), were recruited for data gathering. Data were analyzed using SPSS version 22. Descriptive statistics (percentage, mean, standard deviation), correlation coefficient, independent sample t-test, and multiple linear regression were used. P-values less than 0.05 were considered statistically significant. RESULTS: The total mean score of infertile women's quality of life was 65.68 ± 8.91%. Findings were indicative of infertile women's quality of life in the dimensions of adaptive approach (70.48 ± 15.02%), psychological (67.88 ± 12.06%), family and social (64.63 ± 10.76%), physical, 63.42 ± 11.36%), inhibitory factors/ factors preventing adaptation (60.98 ± 8.24%), related concerns (51.52 ± 10.21%) and sexual life (40.12 ± 14.28%). According to the final multiple linear regression model, women's education (B = 2.57, p < 0.001), spouse's education (B = 1.56, p = 0.046), economic status (B = 1.64, p < 0.001), age of women (B = -0.62, p < 0.001), age of spouse (B = -0.65, p < 0.001), duration of infertility (B = -0.36, p = 0.024) and duration of marriage (B = -0.39, p = 0.022) were the final predictors of the quality of life score in infertile women of the study. CONCLUSION: Given that infertility causes extensive changes in individuals, families, and social dimensions of infertile women, it can affect their quality of life. We can take steps to improve the health of infertile women by promoting various dimensions of their quality of life.

BACKGROUND: Primary ovarian insufficiency is menopause before the age of 40. It can affect the quality of life of afflicted women. Because there is no instrument available for measuring the quality of life of these women, the present study was carried out to develop and assess the psychometric properties of the quality of life scale for women with primary ovarian insufficiency. METHODS: This exploratory sequential mixed method study was performed in two phases. In the qualitative phase (item generation), semi-structured in-depth interviews were conducted with 16 women having primary ovarian insufficiency, and a literature review was performed to generate initial items pool. In the quantitative phase (psychometric evaluation), the face, content, and construct validity (exploratory factor analysis), as well as reliability (internal consistency and test-retest methods), were evaluated. Besides, the responsiveness and interpretability were investigated. RESULTS: During the first phase of the study, the initial item pool was generated with 132 items. After the face and content validity, the number of items was reduced to 40. The results of exploratory factor analysis yielded a 28 item scale with six factors. These factors explained 58.55% of the total variance. The Cronbach's alpha for each factor was more than 0.7. Furthermore, the intraclass correlation coefficient for the entire scale was 0.95. CONCLUSIONS: The primary ovarian insufficiency quality of life scale (POIQOLS) is a valid and reliable tool for accessing the quality of life of women with primary ovarian insufficiency.

Purpose: Prescribing radiotherapy or concurrent chemoradiation for cervicothoracic cancers inevitably leads to esophagitis. The purpose of the current study was to evaluate the correlation between the dose-volume parameters and the esophagitis in patients who received radiotherapy in the cervicothoracic region. Materials and Methods: Forty cancerous patients whose radiotherapy fields were in the cervicothoracic region have been rolled. The correlation between the dosimetric and clinical factors with esophagitis was analyzed through binary logistic regression model and Pearson correlation tests and was quantified with receiver operating characteristic curve. Results: The patients participating in the study were selected from breast (6 cases), lymphoma (7 cases), and head-neck (27 cases) patients with prescription doses of 36-72 Gy. Increasing esophagus mean dose resulted in an increase of acute esophagitis significantly (P = 0.05). Furthermore, by one-gray increase in the esophagus median dose, the possibility of esophagitis increased by 9.3% (P = 0.02). To prevent acute esophagitis (Grade ≥2), D50 should be kept below 7 Gy. To limit acute esophagitis, V40 should be kept below 19% (P = 0.04). Conclusions: Based on the correlation analysis of the current study, concurrent chemoradiotherapy, DMean, D50, D80, and V40 are known as reliable predictive dosimetric parameters of acute esophagitis incidence in patients who experienced radiotherapy in the cervicothoracic region.

BACKGROUND: Body dissatisfaction has been known as an important public health concern that can influence the physical and psycho-social health of adolescents. Hence, health professionals need a valid and reliable tool to assess this problem and its related factors in youth. This study aims to develop and assess the psychometric properties of an indigenous scale for the evaluation of body image and to investigate its association with body weight status among Iranian adolescents. METHODS: This study was conducted on 857 adolescents who completed the body image scale for Youth (BISY) and self-reported their body weight and height. Face, content, and construct validity methods were used to assess the validity of the BISY. Exploratory factor analysis (EFA) was used to assess construct validity. Moreover, the internal consistency of the scale was assessed by calculating Cronbach's alpha coefficient (α), and test-retest reliability was examined using the intra-class correlation coefficient (ICC). To compare the BISY scores across sex and body weight status groups, the Independent samples t-test and the analysis of variance (ANOVA) or Welch tests were used, respectively. RESULTS: Mean age and body mass index (BMI) of participants were 16.5 ± 1.1 years and 22.4 ± 4.5 kg/m2, respectively. The EFA showed a 10-factor construct which explained 57% of the variance. The Cronbach's alpha coefficient for overall items of the scale was 0.896 and ranged from 0.42 to 0.92 for subscales. The test-retest reliability result was acceptable for the BISY (ICC = 0.805). The ICC values ranged from 0.753 to 0.990 for BISY subscales. The BISY total score was significantly higher in girls compared to boys (34.8 ± 12.7 vs. 31.3 ± 10.2; p < 0.001). In girls, the BISY total score was significantly lower in normal-weight girls compared to their overweight (p = 0.009), and obese (p = 0.012) counterparts. This difference was not observed in boys. CONCLUSION: These findings support the reliability and validity of the BISY for the assessment of body image in Iranian adolescents; this scale can be applied as an appropriate tool for the assessment of body image in adolescents in related future studies. Current findings highlight considering body image as an important aspect of intervention programs targeting overweight and obesity in adolescents, specifically girls. Negative body image has been known as an important public health concern that can adversely influence different aspects of adolescents' health. Hence, a valid and reliable tool is necessary to identify adolescents at risk of developing negative body image and its related disorders. There is a lack of an indigenous scale that can comprehensively assess body image and its related factors in Iranian adolescents; hence, the current study aimed to develop and assess the psychometric properties of an indigenous scale for evaluation of body image and further investigate the association between body image and body weight status among Iranian adolescents. The current findings support the reliability and validity of the BISY. In addition, more negative body images were observed in girls compared to boys and in overweight/obese girls compared to their normal-weight counterparts. Therefore, promoting a healthy body image should be incorporated as an important component of future health promotion programs to address obesity, eating disorders, and other health-related concerns among adolescents, specifically girls.
RESUMEN
Background: Body image is known as an important factor affecting different aspects of adolescents' health; however, its relationship with lifestyle, body mass index (BMI), and health-related quality of life (HRQoL) in Iranian adolescents has not been addressed in a conceptual model. Objectives: This study aimed to investigate the network associations among body image, lifestyle, BMI, and HRQoL in adolescent boys and girls. Methods: The present study examined 760 adolescents (15 - 18 years) from Tehran. Adolescents reported their weight and height, according to which the participants' BMIs were calculated. The adolescents' body image, lifestyle, and HRQoL were assessed using a set of questionnaires, including the Body Image Scale for Youth (BISY), Modifiable Activity Questionnaire (MAQ), Eating Habits Checklist, Eating Attitudes Test (EAT-26), and Pediatric Quality of Life Inventory (PedsQLTM). Results: The participants' mean age and BMI were 16.5 ± 1.0 years and 22.4 ± 4.6 kg/m2, respectively. More than one-third of boys (39.9%) and less than a quarter of girls (22.6%) were overweight/obese. In the final model, body image was significantly and directly associated with physical activity, disordered eating, eating habits, and HRQoL in both genders (P < 0.05). Moreover, body image was directly correlated with screen time in boys (P = 0.012) and BMI in girls (P = 0.001). Body image was indirectly correlated with BMI by the mediating role of disordered eating in girls. Moreover, body image was indirectly associated with HRQoL by the mediating role of physical activity and eating habits in both genders and screen time only in boys. Conclusions: The network associations among body image, lifestyle, BMI, and HRQoL revealed a gender-specific pattern among the study population. Body image was a significant determinant of lifestyle and HRQoL in both genders and excessive weight in girls. The present findings would contribute to designing and implementing relevant health promotion interventions.
RESUMEN
To date, there is no valid and reliable instrument to specifically evaluate married adolescent women's sexual and reproductive health (SRH) needs. Hence, the aim of this study was to develop and evaluate the psychometric properties of a questionnaire for assessing married adolescent women (MAW)'s SRH needs. The current exploratory sequential mixed method study was performed in two phases. In the first phase, a preliminary questionnaire was developed based on in-depth interviews with 34 MAW and four key informants as well as a comprehensive literature review. In the second phase, validity of the questionnaire was assessed using face, content, and construct validity and reliability of the questionnaire was assessed using internal consistency and test-retest reliability. Based on qualitative content analysis and literature review, 137 items were extracted. After several modifications of the generated items, a 108-item questionnaire was prepared for the psychometric process. After checking face and content validity, 85 items remained in the study. In the exploratory factor analysis, 11 items were removed and the remaining 74 items were categorised into nine factors. Cronbach's alpha coefficient and the intraclass correlation coefficient were found to be 0.878 and 0.99 for the whole scale, respectively.Impact StatementWhat is already known on this subject? Sexual and reproductive health (SRH) needs of married adolescent women (MAW) are different from those of married adult women or unmarried, sexually active adolescents. However, there are to date no valid and reliable instruments to specifically evaluate the SRH needs of this group of women.What do the results of this study add? The final version of questionnaire consists of 74 items in nine domains including need to improve MAW's sexual quality of life, promote MAW's SRH self-care, improve MAW's SRH self-efficacy, increase MAW's SRH knowledge, increase husband's involvement in MAW's SRH, improve the performance of health care providers, strengthen the family support to married adolescent women, improve family involvement in SRH education of MAW, and provide specific premarital counselling to MAW.What are the implications of these findings for clinical practice and/or future research? The 74-item questionnaire has acceptable validity and reliability. Therefore, it can be used by researchers and policymakers as an appropriate instrument for assessing MAW's SRH needs.

Background and Aim: Providing gender-sensitive health services is emphasized by the World Health Organization. This study aimed to assess and prioritize the needs for the gender-sensitive sexually transmitted infections/human immunodeficiency viruses (STIs/HIV) prevention services by a valid and reliable questionnaire. Methods: This was an exploratory mixed methods sequential study in Shiraz Iran 2019. The first phase was a qualitative study on 37 providers and managers of the services who were recruited using the purposive and then snowball sampling method. In the second phase, following the content analysis of the qualitative data and a review of related literature, a questionnaire was developed and its psychometric properties were evaluated. Then, in the third phase, the questionnaire was used to assess and prioritize the needs through a quantitative descriptive cross-sectional study on all 290 providers of STI/HIV prevention services affiliated with Shiraz University of Medical Sciences. Results: The finding of the qualitative phase showed gender-sensitive STI/HIV prevention services should provide gender-sensitive care and education by the trained personnel and manages with appropriate facilities and equipment. Providing these services also requires supportive policies, intersectoral cooperation, and community capacitation. In the second phase, a questionnaire was developed with 63 items. Assessment of psychometric properties of the questionnaire demonstrated the scale content validity index and ratio (S-CVI = 0.98 and S-CVR = 0.87, respectively), as well as the reliability of the questionnaire (internal consistency = 0.972 and intracluster correlation coefficient = 0.910). Results of the third descriptive phase of the study demonstrated the highest priorities for gender-sensitive education (92.01 ± 11.76%) and care services (92.11 ± 12.04%), respectively. Conclusions: To improve the quality of the services, a gender-based education and care process, as well as a gender-sensitive structure, including gender-sensitive personnel, facilities, and management are necessary. Recognizing and meeting the needs for gender-sensitive services will improve the quality of the services.
RESUMEN
BACKGROUND: Gestational Diabetes Mellitus (GDM) is an underlying cause of maternal and newborn morbidity and mortality all around the world. Timely diagnosis of GDM plays an important role in reducing its adverse consequences and burden. This study aimed to determine diagnostic accuracy of multiple indicators in complete blood count (CBC) test for early prediction of GDM. METHODS: In this prospective cohort study, the data from 600 pregnant women was analyzed. In the study sample, the two-step approach was utilized for the diagnosis of GDM at 24-28 weeks of gestation. We also used the repeated measures of hemoglobin (Hb), hematocrit (Hct), fasting blood sugar (FBS) and red blood cell count (RBC) in the first and early second trimesters of pregnancy as the longitudinal multiple indicators for early diagnosis of GDM. The classification of pregnant women to GDM and non-GDM groups was performed using a statistical technique based on the random-effects modeling framework. RESULTS: Among the sample, 49 women (8.2%) were diagnosed with GDM. In the first and early second trimester of pregnancy, the mean HcT, Hb and FBS of women with GDM was significantly higher than non-GDMs (P < 0.001). The concurrent use of multiple longitudinal data from HcT, Hb, RBC and FBS in the first and early second trimester of pregnancy resulted in a sensitivity, specificity and area under the curve (AUC) of 87%, 70% and 83%, respectively, for early prediction of GDM. CONCLUSIONS: In general, our findings showed that the concurrent use of repeated measures data on Hct, Hb, FBS and RBC in the first and early second trimester of pregnancy might be utilized as an acceptable tool to predict GDM earlier in pregnancy.

PURPOSE: This study investigated the correlation between the prescription dose and dose to the Manchester and International Commission on Radiation Units and Measurements-report 38 (ICRU-38) lymphatic trapezoid points during high-dose-rate (HDR) brachytherapy of locally advanced cervical cancer with (Cobalt-60) 60Co . METHODS AND MATERIALS: A retrospective study was designed for; patients with locally advanced cervical cancer, treated by external beam radiotherapy and concurrent weekly Cisplatin-based chemotherapy, had no extended parametrial invasion and was treated by tandem-ovoid set, from 2017 to 2020. Groupe Européen de Curiethérapie-European Society for Radiotherapy and Oncology (GEC-ESTRO) based target's volume, ICRU-89 revised version of Manchester points A and B, and ICRU-38 lymph node surrogate points were determined, and their dose was recorded. Paired sample t-test, linear regression analysis, and Pearson correlation analyses were done considering a statistical significance level of 0.05 and using IBM SPSS statistics (Version 23, IBM Crop.). RESULTS: Seventy-four brachytherapy cases were included. A positive and strong correlation was observed between D90 of clinical target volume (CTVHR) and points A and B dose for CTVHRã 15 cc and ã 35 cc. Strong and significant (p < 0.05) correlations were achieved between pelvic wall points dose and D90 and D100 of the obturator and between D50 and hot points of internal iliac lymph nodes. A strong correlation was obtained between D50 and D90 of external iliac lymph nodes and their ICRU points. CONCLUSIONS: Strong correlations were obtained between dose to the pelvic lymphatic chains and their historical ICRU-38 surrogate points during HDR brachytherapy of locally advanced cervical cancer patients with 60Co tandem-ovoid applicator sets. The correlation strength between point A and prescription dose highly depends on the CTVHR volume.

Background: Life expectancy is one of the key indicators for investigating the overall health status of a population. Thus, analyzing the trend of this demographic measure is of great importance for planning health and social services in different societies. In this study, we aimed to model the trends of life expectancy in Asia, regions of Asia, and Iran over the past six decades. Methods: The annual life expectancy at birth data sets were extracted for Iran and the total Asia population between 1960 and 2020 from the database provided by the Our World in Data website. The trend analysis was performed using the joinpoint regression model. Results: During the study period, Iranians and Asians have, respectively, experienced about 32 and 28.6 years increase in life expectancy. The results from joinpoint regression showed that the average annual percent change (AAPC) of life expectancy was positive for all regions of Asia, and ranged from 0.4% for Central Asia to 0.9% for Southern Asia. In addition, the estimated AAPC in Iranian people was about 0.1 higher than the total Asian population (0.9% vs. 0.8%). Conclusion: Despite protracted wars, poverty, and social inequality in some parts of Asia, life expectancy has drastically increased in this continent over the last decades. However, life expectancy in Asia (and Iran) is still remarkably lower than in more developed parts of the world. To elevate life expectancy to a higher level, the policymakers in Asian countries should put more effort into improving the standards of living and access to health facilities in their societies.
