The Impact of Prophylactic Post-Chemotherapy G-CSF on the Relapse Rates in Patients with Acute Myeloid Leukemia: A Meta-Analysis.

This meta-analysis evaluated the impact of prophylactic post-chemotherapy granulocyte colony-stimulating factor (G-CSF) in patients with acute myeloid leukemia (AML). Overall, the relapse rate, overall survival, event-free survival, and mortality rate were similar in G-CSF (+) compared to G-CSF (-) patients. However, the relative risk (RR) of relapse was higher in children and in secondary AML patients who were treated with G-CSF compared to the G-CSF (-) group [RR, 95% confidence interval: 1.26, 1.04-1.52, and 1.12 (1.02-1.24)]. Treatment with post-chemotherapy G-CSF should be prescribed with caution in pediatric patients with AML and secondary AML as possibly increasing the relapse risk.

The prevalence of left ventricular hypertrophy associated with type-2 diabetes in Shiraz, Iran: a cross-sectional study.

BACKGROUND: Left ventricular hypertrophy (LVH) is a common diagnosis in patients with cardiovascular disease (CVD). The prevalence of LVH among patients with Type-2 Diabetes Mellitus (T2DM), high blood pressure and aging is higher than the healthy population and has been independently associated with an increased risk for future cardiac event, including stroke. The aim of this study is to identify the prevalence of LVH among T2DM subjects and evaluate its association with related risk factors of CVD patients in the metropolis of Shiraz, Iran. The novelty of this study is that there has been no known published epidemiological study related to the relationship of LVH and T2DM on this unique population. MATERIALS AND METHOD: This cross-sectional study was designed based on collected data of 7715 free dwelling subjects in the community-based Shiraz Cohort Heart Study (SCHS) from 2015 to 2021, ages 40-70 years. Overall, 1118 subjects with T2DM were identified in the SCHS and after exclusion criteria, 595 subjects remained eligible for study. Subjects with electrocardiography (ECG) results, which are appropriate and diagnostics tools, were evaluated for the presence of LVH. Thus, the variables related to LVH and non-LVH in subjects with diabetes were analyzed using version-22 statistical package for social sciences software program to ensure consistency, accuracy, reliability, and validity for final analysis. Based upon related variables and identifying LVH and non-LVH subjects, the relevant statistical analysis was implemented to ensure its consistency, accuracy, reliability, and validity for final analysis. RESULTS: Overall, the prevalence of diabetic subjects was 14.5% in the SCHS study. Furthermore, the prevalence of hypertension in the study subjects aged 40-70 years was 37.8%. The prevalence of hypertension history in T2DM study subjects for LVH compared to non-LVH was (53.7% vs. 33.7%). The prevalence of LVH among patients with T2DM as the primary target of this study was 20.7%. Analytical findings comparing both LVH and non-LVH subjects who have T2DM identified significance for variables in the older (≥ 60) mean and categorical age group (P < 0.0001), history of hypertension (P < 0.0001), mean and categorical duration of hypertension in years (P < 0.0160), status of controlled versus uncontrolled hypertension level (P < 0.0120), the mean systolic blood pressure (P < 0.0001) as well as mean duration years of T2DM and categorical duration of diabetes in years (< 0.0001 and P < 0.0060), mean fasting blood sugar (< 0.0307) and categorical status of FBS Level (mg/dl): controlled and uncontrolled FBS status of controlled vs. uncontrolled FBS levels P < 0.0020). However, there were no significant findings for gender (P = 0.3112), diastolic blood pressure mean (P = 0.7722) and body mass index (BMI) mean and categorical BMI (P = 0.2888 and P = 0.4080, respectively). CONCLUSION: The prevalence of LVH in the study increases significantly among T2DM patients with hypertension, older age, years of hypertension, years of diabetes, and higher FBS. Thus, given the significant risk of diabetes and CVD, evaluation of LVH through reasonable diagnostic testing with ECG can help reduce the risk of future complications through the development of risk factor modifications and treatments guidelines.

Correlation of Serum Ferritin Level with Heart T2 MRI in Transfusion Dependent Thalassemia: a Systematic Review and Meta-Analysis.

BACKGROUND: Cardiac complications in patients with transfusion-dependent thalassemia (TDT) are one of the major causes of mortality in these patients which annually impose economic burden on the endemic countries. Heart T2 MRI is a good modality for evaluating iron overload. Our aim was to investigate the pooled correlation between the serum ferritin level and heart iron overload in TDT patients and compare the effect size in different geographical areas. METHODS: PRISMA checklist was used to summarize the literature search. Three major databases were used for the papers and exported into endnote for screening. Data were extracted into an Excel spreadsheet. The data were analyzed using STATA software. CC was considered as the effect size, and the amount of heterogeneity was indicated by I-squared. Meta-regression was used for age. Also, sensitivity analysis was performed. RESULTS: The present study showed a statistically significant negative correlation of the serum ferritin level with heart T2 MRI: -0.30 (95% CI -0.34, -25). This correlation was not significantly affected by the patients' age (p-value: 0.874). Given different geographic area, most of the studies from different countries indicated that the correlation between the serum ferritin and heart T2 MRI was statistically significant. CONCLUSIONS: The pooled analysis showed a significant negative moderate correlation between the serum ferritin level and heart T2 MRI in patients with TDT, regardless of their age. This issue underscores the importance of periodical evaluation of serum ferritin level in patients with TDT in developing countries with low financial supports and limited resources. Further studies are suggested to evaluate the pooled correlation of the serum ferritin level with iron concentration of other vital organs.

Risk Factors for the Occurrence of Asymptomatic Brain Lesions in Patients with ß-Thalassemia: a Systematic Review and Meta-Analysis.

BACKGROUND: Several factors, including increased platelet aggregation, decreased platelet survival, decreased antithrombotic factors cause a hypercoagulable state in thalassemia patients. This is the first meta-analysis designed to summarize the association of age, splenectomy, gender, and serum ferritin and hemoglobin levels with the occurrence of asymptomatic brain lesions in thalassemia patients using MRI. METHODS: This systematic review and meta-analysis was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist. We searched four major databases and included eight articles for this review. The quality of the included studies was assessed based on the Newcastle-Ottawa Scale checklist. Meta-analysis was performed using STATA 13. Odds ratio (OR) and standardized mean difference (SMD) were considered as effect sizes for comparing the categorical and continuous variables, respectively. RESULTS: The pooled OR for splenectomy in patients with brain lesions compared to those without lesions was 2.25 (95% CI 1.22 - 4.17, p = 0.01). The pooled analysis for SMD of age between patients with/without brain lesions was statistically significant, 0.4 (95% CI 0.07 - 0.73, p = 0.017). The pooled OR for the occurrence of silent brain lesions was not statistically significant in males compared to females, 1.08 (95% CI 0.62 - 1.87, p = 0.784). The pooled SMD of Hb and serum ferritin in positive brain lesions compared to negatives were 0.01 (95% CI -0.28, 0.35, p = 0.939) and 0.03 (95% CI -0.28, 0.22, p = 0.817), respectively, which were not statistically significant. CONCLUSIONS: Older age and splenectomy are risk factors for developing asymptomatic brain lesions in ß-thalassemia patients. Physicians should consider a careful assessment of high-risk patients for starting prophylactic treatment.

The Prevalence of Obstructive Sleep Apnea and Associated Symptoms among Patients with Sickle Cell Disease: A Systematic Review and Meta-analysis.

Previous studies have shown that patients with sickle cell disease (SCD) are at high risk for obstructive sleep apnea (OSA). In the current study, we aimed to systematically review the literature to address the prevalence of OSA and associated symptoms among patients with SCD. Electronic databases, including Web of Science, Scopus, PubMed, Google Scholar, and Embase were systematically searched to identify the relevant original articles on patients with SCD. Newcastle Ottawa scale was used for quality assessment. Data were pooled by using random effects models. Subgroup analyses were performed by age groups. Thirty-nine studies containing details of 299,358 patients with SCD were included. The pooled results showed that more than half of these patients had OSA with different severities. The prevalence rates of OSA among children with apnea hypopnea index (AHI) cutoffs of above 1, 1.5, and 5 were 51% (95% confidence interval (CI) 36-67%), 29% (95% CI 19-40%), and 18% (95% CI 14-23%), respectively. The prevalence of OSA among adults with AHI cutoff of 5 was 43% (95% CI 21-64%). The pooled rates of snoring, nocturnal enuresis, nocturnal desaturation, and daytime sleepiness were 55% (95% CI 42-69%), 37% (95% CI 33-41%), 49% (95% CI 26-72%), and 21% (95% CI 12-30%), respectively. Given the high prevalence of OSA in patients with SCD, probable greater burden of SCD complications, and irreversible consequences of OSA, screening for OSA symptoms and signs seems useful in these patients. By screening and identifying this heterogeneous disorder earlier, available treatment modalities can be individualized for each patient.

Isoniazid prophylaxis in liver transplant recipient with latent tuberculosis: Is it harmful for transplanted liver?

BACKGROUND: Liver transplantation (LT) is considered the only treatment for patients with end-stage liver disease and, despite its incredible impacts on the patients' health status, places them in an immunocompromised state in which opportunistic infection would find a way to present. Latent tuberculosis infection (LTBI) is the most common form of TB and can be diagnosed through tuberculin skin test (TST) or Interferon-Gamma Release Assays (IGRA). LT recipients are at significant risk of TB activation. There is no strict guideline to approaching these cases though, in most centers, Isoniazid (INH) would be prescribed prophylactically. INH is a hepatotoxic medication and can have adverse effects on the transplanted liver. There is no consensus on this issue; therefore, we aimed to survey the potential hepatotoxic effects of INH among LT recipients in Shiraz, Iran. METHODS: A retrospective cohort study was conducted among LT candidates and recipients at Abu Ali Sina Organ Transplantation Center between 1993 and 2019. All the cases underwent TST and chest X-ray to detect LTBI. All the LTBI were treated with INH from 6-9 months and followed by the level of liver enzymes for quick detection of hepatotoxicity. A control group was selected among LT recipients and matched for age, gender, MELD score, and donor age. RESULTS: Among 4895 medical records reviewed, 55 (1.12%) cases had LTBI. Neither INH-related hepatotoxicity, nor signs and symptoms that were suspicious to TB reactivation were reported. Overall, three deaths were reported, two because of myocardial infarction and one due to pneumonia. Ten patients (18.2%) experienced acute rejection as confirmed with pathology and responded to methylprednisolone. Aspartate aminotransferase (AST) was diminished from pre-LT time to the first time after transplantation; after that, it showed a steady pattern. Meanwhile, Alanine transaminase (ALT) was constant before and one stage later and decreased after that. Statistical analyses only showed significant changes in the total bilirubin titer between the case and control groups. CONCLUSION: This survey showed prophylactic management of LTBI with INH in LT candidates and recipients was associated with no hepatotoxicity or related death. It seems that INH prophylaxis is safe in LT settings and can efficiently prevent TB activation; however, careful monitoring for adverse effects and liver enzymes elevation is highly recommended.

Ten-year atherosclerosis cardiovascular disease (ASCVD) risk score and its components among an Iranian population: a cohort-based cross-sectional study.

BACKGROUND: Atherosclerotic cardiovascular disease (ASCVD) continues to be the first cause of mortality globally. Effective preventive strategies require focused efforts to clarify ASCVD risk factors in different subgroups of a population. This study aimed to identify individuals at higher risk of ASCVD among Shiraz University employees to guide decision-making for primary prevention. METHODS: This cohort-based cross-sectional study was conducted on data of 1191 participants (25-70 years old) from Shiraz University employees selected by systematic random sampling. The 10-year ASCVD risk was calculated with an ASCVD risk score estimator developed by the American College of Cardiology/American Heart Association (ACC/AHA). To analyze the data, descriptive and chi-square tests were used. All statistical analyses were conducted using the SPSS version 16.0 software. The p-value < 0.05 was considered a significant level. RESULTS: This study demonstrated that 75.3% of the participants had low risk scores, whereas 13.2% and 2.5% of them had intermediate and high risk scores, respectively. Additionally, it revealed that among women 93.7%, 2.7%, and 0.6% had low intermediate and had high risk scores, respectively, whereas among men, 61.5%, 21.1%, and 3.9% had low intermediate and high risk scores, respectively. Based on the results of the chi-square test, men were significantly more prone to ASCVD (38.5%) than women (6.3%) were. Interestingly, 40.9% of known cases of hypertension had uncontrolled blood pressure, and 62.5% of individuals without any history of hypertension, who were considered new cases of hypertension, had abnormal blood pressure. Furthermore, 38.5% of diabetic patients and 1.6% of people who did not have a history of diabetes had abnormal serum fasting blood sugar. CONCLUSION: It was revealed that nearly 15.7% of participants were at intermediate and high risk of developing ASCVD in the next 10 years with greater risk in men. Considerably, some of hypertensive and diabetic participants had uncontrolled blood pressure and blood sugar levels, respectively. New cases of diabetes and hypertension were also recognized in our study. Therefore, to address the primary prevention of ASCVD in this population, it is necessary to have plans for targeted interventions, which can be effective in modifying their risk factors.

Current Status and Outcomes of Critical Traumatic Brain Injury (GCS = 3-5) in a Developing Country: A Retrospective, Registry-Based Study.

BACKGROUND: Patients sustaining critical TBI [initial Glasgow Coma Scale (GCS) ≤ 5] generally have poor outcomes. Little is known about the frequency, mortality rate, and functional outcomes of such patients in Iran. METHODS: In this retrospective, registry-based cohort study, the demographic and clinicoradiological findings of TBI patients were queried from March 21, 2017, to March 21, 2020. We included TBI patients with initial GCS of 3-5. The functional outcome was assessed using the Glasgow Outcome Score-extended 6 (GOSE-6) months after the hospital discharge. Patients were classified as having unfavorable (GOSE-6 ≤ 4) and favorable (GOSE-6 > 4) outcomes. Gathered data were compared between groups. Multivariable logistic regression analysis was done to find factors affecting the outcome. RESULTS: Four hundred ninety-seven patients (mean age = 37.59 ± 17.89) were enrolled, and 69.2% had unfavorable outcomes. Elderly patients (age ≥ 65 years) were highly overrepresented among the unfavorable group. 48.9% had bilateral fixed dilated pupils (BDFP), who mostly attained unfavorable outcomes. The overall in-hospital mortality rate was 50.3%. The in-hospital mortality rate was appalling among elderly patients with BFDP and GCS 3( 90%) and GCS 4(100%). Age ≥ 65 years [odds ratio (OR) 3.45, 95% confidence interval (CI) 1.19-10.04], and BFDP (OR 4.48, 95% CI 2.60-7.73) increase the odds of unfavorable outcomes according to the regression analysis. CONCLUSION: The survival rate and favorable outcomes of critical TBI patients are generally poor. However, we believe that the neurotrauma surgeons should discuss with patients' proxies and explain the clinical conditions and possible outcomes.

Cytokine Levels in Patients with ß-Thalassemia Major and Healthy Individuals: a Systematic Review and Meta-Analysis.

BACKGROUND: Cytokine levels in patients with ß-thalassemia major (ß-TM) have been assessed in several studies. Accordingly, a wide variety of immune disturbances has been shown in patients with thalassemia. Recurrent transfusions cause iron overload, which induces an increase in the production of cytokines. However, no systematic approach or meta-analysis has been done to provide a clear feature of cytokine levels in ß-TM. The present meta-analysis aimed to summarize the existing evidence regarding different levels of cytokines in patients with Β-TM compared to healthy controls. METHODS: This study was performed according to the PRISMA checklist. A systematic search was done in Web of Science (ISI), Scopus, and PubMed databases. The quality of the included studies was assessed based on the New-castle-Ottawa Scale. Meta-analysis was run via STATA 13 software. The standardized mean difference was considered the effect size for comparing the continuous variables. RESULTS: This meta-analysis included 16 studies conducted on 805 ß-TM patients and 624 healthy individuals (with the mean age of 16.10 ± 4.33 and 16.22 ± 3.78, respectively). The results showed significantly higher levels of Tumor Necrosis Factor-alpha (TNF-α), Interleukin-6 (IL-6), and IL-10 in patients with ß-TM compared to the healthy controls. CONCLUSION: The results indicated that the levels of both inflammatory and anti-inflammatory cytokines were higher in patients with ß-TM compared to the healthy population, which could be associated with higher levels of oxidative markers in these patients. Further studies are suggested to evaluate the difference in cytokine levels among different types of thalassemia.

The Impact of Smoking on Clinical Outcomes after Percutaneous Coronary Intervention in Women Compared to Men.

BACKGROUND: For decades, cardiovascular diseases (CVD) have been known as men's disease. However, recent research studies showed that they have become more common in women. Smoking is a strong risk factor for CVD especially that of coronary artery disease (CAD). Several studies reported that women are more susceptible to drastic sequels of smoking than men. There is limited data regarding the impact of smoking on post-revascularization clinical events stratified by gender. This study aimed to investigate if gender significantly changes the incidence of adverse clinical outcomes after percutaneous coronary intervention (PCI) among those with history of smoking. METHODS: Participants were selected from two hospitals from 2003 to 2019. Among patients who had PCI (index PCI), those with stable CAD who underwent elective PCI were included. Exclusion criteria were defined as primary PCI and those with multiple prior revascularizations. Participants were followed up seeking for major adverse cardiac events (MACE) including revascularization (PCI or coronary artery bypass grafting), myocardial infarction, and coronary death in three time intervals according to the time of index PCI (short term: up to 24 hours, mid-term: 24 hours to less than 6 months, and long term: more than 6 months). RESULTS: Of the 1799 patients, 61% were men and 47.08% had history of smoking (75% of the smokers were men). At the time of index PCI, smokers were significantly younger than nonsmokers. Also, MACE were significantly higher in smokers than nonsmokers, which was particularly pronounced at the long-term interval. In the nonsmokers group, there was no difference in MACE occurrence between men and women. However, of the smokers, women showed significantly higher MACE rate compared with men peers. CONCLUSION: Smoking makes women more prone to MACE in comparison to men among patients with stable CAD after PCI with drug-eluting stent.

Incidence Rate of COVID-19 Infection in Hemoglobinopathies: A Systematic Review and Meta-analysis.

During the coronavirus-19 disease (COVID-19) pandemic, several studies were performed to determine the mortality and incidence rates of coronavirus infection among patients with hemoglobinopathies. However, there has been no systematic approach or meta-analysis to evaluate the results worldwide. This meta-analysis summarized the existing evidence of incidence and mortality rates of COVID-19 and related risk factors among patients with hemoglobinopathies with a focus on ß-thalassemia (ß-thal) and sickle cell disease. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Two authors independently screened the articles, extracted eligible ones, and assessed the quality of studies using the Joanna Briggs Institute (JBI) checklist. The collected data were analyzed by the Stata software. The amount of heterogeneity was demonstrated by the I2 test. The incidence of COVID-19 among patients with a hemoglobinopathy, ß-thal and sickle cell disease was 4.44, 1.34, and 17.22 per 100,000 person-day, respectively, to June 15 2020. The mortality rate of COVID-19 in patients with hemoglobin (Hb) disorders was calculated as 1.07 per 1000 person-day in the same period. Our findings showed a higher incidence rate of COVID-19 in sickle cell disease patients compared to the general population. A slightly higher mortality rate was also observed in patients with hemoglobinopathies compared to the general population, possibly due to the associated risk factors and comorbidities in this vulnerable group, which underscore special care, timely diagnosis and management along with current immunization, were crucial in decreasing the frequency, disease severity and mortality of these patients.

The Prevalence of Hypothyroidism among Patients With ß-Thalassemia: A Systematic Review and Meta-Analysis of Cross-Sectional Studies.

As a cause of chronic blood transfusions, iron overload is an important issue in ß-thalassemia (ß-thal) patients that leads to multiple organ dysfunctions. This is an updated meta-analysis conducted to summarize the existing evidence of the prevalence of hypothyroidism (HT) among patients with transfusion-dependent (TDT) and non transfusion-dependent ß-thal (NTDT) and for the first time we meta-analyzed the relationship between ferritin level and HT. This systematic review and meta-analysis were done according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. We searched databases including Web of Science (ISI), Scopus, PubMed, Embase, and Scholar. The quality of the included studies was assessed based on the Newcastle-Ottawa scale (NOS) checklist. Meta-analysis was done using Stata statistical software. The pooled prevalence of total HT, subclinical HT, and overt HT among ß-thal patients was 13.25 [95% confidence interval (95% CI): 10.29-16.21; 11.84, 95% CI: 8.43-15.25 and 12.46, 95% CI: 1.05-23.87], respectively. The prevalence of total HT was 16.22% (95% CI: 12.36-20.08) in TDT and 7.22% (95% CI: 3.66-10.78) in NTDT patients. Serum ferritin (SF) levels were significantly lower in euthyroid compared to hypothyroid patients [standard mean difference (SMD) -2.15 (95% CI: -3.08, -1.21, p value <0.001]. The prevalence of HT was higher in TDT compared to NTDT patients. Moreover, our results showed a significant association of high serum ferritin (SF) levels with hypothyroidism in ß-thal patients. Both of these findings highlight the importance of prevention measures and timely diagnosis and management of iron overload in ß-thal patients.

Fragmented QRS as an early predictor of left ventricular systolic dysfunction in healthy individuals: a nested case-control study in the era of speckle tracking echocardiography.

BACKGROUND: Several studies addressed the association between fragmented QRS (fQRS) on 12-lead EKG and left ventricular (LV) dysfunction in patients with a variety of cardiovascular disorders. We tested such association in healthy individuals. METHODS: Out of 500 healthy participants without -overt cardiovascular disease from the Shiraz Heart Study cohort, we identified 20 subjects with fQRS (cases) and 20 peers without fQRS (controls). Global LV longitudinal strain (GLS) was measured by speckle tracking echocardiography in the two groups. Comparison was made between case and control groups by using chi-square or independent sample t-test or ANOVA. RESULTS: Age, gender, ejection fraction, LV volume and dimensions did not differ between the case and the control groups. Overall, 14 subjects out of 40 had reduced GLS (≤20%) and 10 of them (25%) had fQRS. GLS was significantly lower in the group with fQRS than in the control group (19.9 ± 1.8 vs 21.4 ± 1.6; p = 0.009). CONCLUSIONS: Healthy subjects with fQRS present regional LV systolic dysfunction, assessed by GLS, in the presence of a normal ejection fraction. These data suggest that fQRS may be a promising tool to identify apparently healthy subjects with regional LV systolic dysfunction.

High risky behavior and HIV/AIDS knowledge amongst street children in Shiraz, Iran.

Background: Street children around the world are accompanying a wide range of risky behaviors. The most common ones include risky sexual behavior, substance and alcohol abuse, and violence. This study aimed to assess risk behaviors and HIV knowledge of street children in Shiraz. Methods: A total of 329 street children (7-18 years of age who spend days or nights on streets with or without their family for earning money) were interviewed through 2014-2016 in Shiraz. Data were collected through a structured interview about high-risk behaviors and HIV/AIDS Knowledge based on a form and questionnaire. Street children were asked to identify HIV/AIDS mode of transmission. All correct answers were scored as one (1), and incorrect, "don't know" responses and no responses scored as zero. The data were analyzed by SPSS software 16 (SPSS, Inc. Chicago, USA) using the Independent t-test and chi-square test, and Pearson's correlation test. P value< 0.05 was considered as statistically significant Results: The mean ± SD age was 13.46±3.09. A total of 86.6% of them were boys. A total of 97.6% of them reported staying with their parents. Street children reported sleeping place as follow: with their parents (n=312, 94.8%), sharing accommodation with other kids (n=13, %4), sleeping in parks (n=2, 7%), and one with relatives. The frequency of smoking, alcohol drinking, and drug abuse were 35 (10.6%), 47 (14. 3%), and 6 (1.8%) respectively. A total of 43 (13.1%) street children reported sexual activity, among them 30 (9.1%) had sexual activity without a condom. Mean ± SD HIV/AIDS knowledge scoring of street children was, 4.1±3.9. Conclusion: Special programs should be implemented in order to reduce high-risk behavior among street children. Intervention should include increasing awareness about alcohol and drug abuse, HIV/AIDS knowledge, sexual and verbal abuse through an organized system with the help of peer education.

Trends in age at first marriage in women and related factors: A population-based study in southwestern Iran.

Marriage and related processes seem to show individual tendencies but are in fact social phenomena. The aim of this study was to identify, among women, trends in age at first marriage and its related factors. In this cross-sectional study, the target population was women in households in Fars Province, Iran. To identify main effects of variables associated with age at marriage, multiple linear regression modeling was used without interactions. Women's age, women's and their husbands' occupations and educational levels, and place of residence were included in multiple linear regression modeling. A total of 3074 ever-married women were interviewed. A steep upward trend over time in age marriage was observed. The mean age at first marriage was 16.9 ± 3.4 years in women who married during the period from 1954 to 1974, and 21.9 ± 4.1 years among those who married during 2005-2014. Age at first marriage was significantly positively associated with women's and men's educational levels and with husband's employment status as laborers (p = 0.017) and negatively associated with husbands being employees (compared to being unemployed) (p < 0.001). Health providers should focus on increasing public awareness of factors associated with early and with delayed marriage.

Slums' access to and coverage of primary health care services: a cross-sectional study in shiraz, a metropolis in southern iran.

BACKGROUND: The United Nations has predicted that the population of slum dwellers will have grown from one billion people worldwide to 2 billion by 2030. This trend is also predictable in Iran. In the Iranian metropolis of Shiraz, more than 10% of the residents live in slum areas. There are several problems regarding the delivery of social services in these areas. The aim of this study was to evaluate slums dwellers' access to and coverage of health care. METHODS: This cross-sectional face-to-face study included 380 household of slum dwellers via stratified random sampling. Demographics, accessibility of health services, coverage of health care, and route of receiving health services were recorded through interviews. RESULTS: Approximately, 21.6% of the households had no physical access to health centers. The coverage rate of family planning programs for safe methods was 51.4% (95% CI: 48.86-53.9%). Vaccination coverage among children under 5 years old was 98% (95% CI: 97-99%). Furthermore, 34% of pregnant women had not received standard health care due to a lack of access to health centers. CONCLUSION: Limited access to health services along with inadequate knowledge of slum residents about health care facilities was the main barrier to the utilization of the health care in the slums.

Comparison of atherosclerotic cardiovascular disease (ASCVD) and Framingham risk scores (FRS) in an Iranian population.

Background: Framingham risk score (FRS) and Atherosclerotic Cardiovascular Disease risk score (ASCVDrs) are widely used tools developed based on the American population. This study aimed to compare the ASCVDrs and FRS in an Iranian population. Method: The participants of the Fasa Adult Cohort Study and the patients of the cardiovascular database of Vali-Asr Hospital of Fasa, aged 40-80 years, were involved in the present cross-sectional study. After excluding non-eligible participants, the individuals with a history of myocardial infarction or admission to the cardiology ward due to heart failure were considered high-risk, and the others were considered low-risk. The discriminative ability of FRS and ASCVDrs was evaluated and compared using receiver operating characteristic curve analysis. The correlation and agreement of ASCVDrs and FRS were tested using Cohen Kappa and Spearman. Results: Finally, 8983 individuals (mean age:53.9 ± 9.5 y, 49.2 % male), including 1827 high-risk participants, entered the study. ASCVDrs detected a greater portion of participants as high-risk in comparison with FRS (28.7 % vs. 15.7 %). ASVD (AUC:0.794) had a higher discriminative ability than FRS (AUC:0.746), and both showed better discrimination in women. Optimal cut-off points for both ASCVDrs (4.36 %) and FRS (9.05 %) were lower than the original ones and in men. Compared to FRS, ASCVDrs had a higher sensitivity (79.3 % vs. 71.6 %) and lower specificity (64.5 % vs. 65.1 %). FRS and ASCVDrs had a moderate agreement (kappa:0.593,p-value<0.001) and were significantly correlated (Spearman:0.772,p-value<0.001). Conclusions: ASCVDrs had a more accurate prediction of cardiovascular events and identified a larger number of people as high-risk in the Iranian population.

Factors Associated with Chronic Rejection in Liver Transplant Recipients: A Retrospective Cohort Study From Shiraz Organ Transplant Center.

OBJECTIVES: Identification of chronic rejection risk factors in liver transplant recipients is critical for early detection and prevention of further graft loss. We investigated characteristics of liver transplant recipients who had experienced chronic rejection and the associated risk factors versus patients without chronic rejection. MATERIALS AND METHODS: Data from 3022 adult liver transplant recipients between 2011 and 2018 were analyzed; of these, 80 patients had experienced chronic rejection. The control group included 98 randomly selected liver transplant recipients who did not have chronic rejection. RESULTS: The age of the recipients and the donors was significantly lower in the group with chronic rejection versus the group without chronic rejection.The results indicated that chronic rejection was significantly associated with the sex of the recipients (hazard ratio 3.2, 95% CI 1.77-6.08; P < .001) and with the sex concordance between the recipients and donors (hazard ratio 2.93, 95% CI 1.67-5.13; P < .001, respectively). Also, in the group without chronic rejection, there were no male donors; however, the group with chronic rejection had mostly male donors (P <.001). Cold ischemia time was longer in patients with chronic rejection versus that shown in the control group (P = .031), and there was a significant difference between the 2 groups in acute rejection frequency (P < .001). CONCLUSIONS: Recipient sex and sex concordance were independent risk factors for chronic rejection. Most transplantrecipients with chronic rejection responded to medicaltreatment, and the rate of graftloss was low among our recipients.

Design and rationale for a randomized, open-label, parallel clinical trial evaluating major adverse cardiovascular events (pharmacological treatment versus diet control) in patients with high-normal blood pressure: the PRINT-TAHA9 trial.

BACKGROUND: The distinction between normal and high blood pressure remains a debated topic, with varying guidelines on when to start medication. Contemporary guidelines advocate for the initiation of antihypertensive therapy in individuals who present with high-normal blood pressure, particularly those exhibiting elevated 10-year atherosclerotic cardiovascular disease (ASCVD) risk scores. Despite these recommendations, there is a notable lack of direct evidence supporting the efficacy of treating high-normal blood pressure to prevent major adverse cardiovascular events (MACE). METHODS: The PRINT-TAHA9 trial, a unicentric, randomized, open-label, controlled, parallel clinical study, seeks to explore the effects of intensive blood pressure control on MACE in participants with high-normal blood pressure. We will enroll 1620 adults aged 18 years and above with a systolic blood pressure range of 130-140 mmHg, diastolic blood pressure under 90 mmHg, and atherosclerotic cardiovascular disease (ASCVD) risk score exceeding 7.5%. The study will be executed in five distinct phases, with each phase enrolling between 300 and 400 participants. Participants will be randomly assigned to either the treatment group receiving antihypertensive medication (amlodipine/valsartan) and a low-salt/low-fat diet or to the control group receiving a similar diet. Follow-up visits are scheduled every 6 months over a 3-year period to monitor blood pressure, evaluate medication adherence, document any adverse events, and adjust the intervention as necessary. Cox proportional hazards regression analysis will be employed to examine the disparities between the two arms. DISCUSSION: Despite guidelines promoting early treatment of elevated blood pressure, the debate continues due to insufficient evidence that such interventions significantly reduce the occurrence of MACE. This trial seeks to address this critical evidence gap. TRIAL REGISTRATION: The PRINT-TAHA9 trial was registered in October 2019 with the Iranian Registry of Clinical Trials (IRCT.ir) under the registration number IRCT20191002044961N1. https://irct.behdasht.gov.ir/trial/43092 .

Factors Associated With Recurrence of Underlying Diseases Among Liver Transplant Recipients: A Single-Center Study.

OBJECTIVES: The recurrence of underlying diseases remains a major cause of graft failure after liver transplant. This study aimed to identify factors associated with the recurrence of underlying diseases and investigate the incidence of these factors and recurrence at the main liver transplant center in Iran. MATERIALS AND METHODS: We included adult liver transplant recipients followed at Shiraz Transplant Center between 2011 and 2018 with a confirmed diagnosis of recurrence of underlying disease in our study. We reviewed medical records and extracted data on demographic characteristics, clinical and paraclinical features, medication use, and current status. We used a systematic random sampling method to select a control group of 95 transplant recipients who did not have recurrence. Of 3022 total transplant recipients, 76 recipients experienced a recurrence of their underlying disease. RESULTS: Model for End-Stage Liver Disease score, underlying disease, recipient blood group, donor sex, donor blood group, and rejection frequency were significantly different between study groups with and without recurrence of underlying diseases. Liver transplant recipients with recurrence had lower mean Model for End-Stage Liver Disease score. Recipients with recurrence also had higher rate of drug consumption (eg, prednisolone, tacrolimus, mycophenolate mofetil, sirolimus). Regression analysis showed that donor sex and rejection frequency had an effect on disease recurrence. Death occurred more frequently in liver transplant recipients with recurrence than in the control group (39.5% vs 26.3%), butthe difference was not significant. CONCLUSIONS: Donor sex and acute rejection frequency are independent factors predictive of the recurrence of underlying disease. Modifying risk factors can help minimize the recurrence of underlying diseases after liver transplant.
