ABSTRACT
Cerebral venous sinus thrombosis (CVST) is an uncommon disorder with an increased mortality risk. Data on the sex-specific clinical profile and related factors can be practical in clinical diagnosis and management. Thus, we aimed to assess CVST characteristics in Shahrekord, the most elevated city among the centers of the provinces of Iran, referred to as the Roof of Iran. In this retrospective cross-sectional study, we reviewed the hospital records of 127 CVST patients between April 2013 and June 2023 to analyze the demographic characteristics, clinical profile, disease outcomes, and risk factors. STROBE guidelines were used to report this study. Females comprised 65.3% of the study. Females' age was almost equal to male patients (37.51 ± 13.95 years vs 38.09 ± 16.18 years, Pâ =â .832), and more than half of the patients (59.1%) were married. Clinical characteristics showed no significant difference between the sexes. In contrast to males, females had multifarious risk factors. However, the main risk factors for both sexes were CVST and hypertension. Most patients had 1 sinus affected (55.9%), and the location of thrombosis was mainly in the right transverse sinus in males (38.63%) and superior sagittal sinus in females (33.73%). However, those with more than 2 affected sinuses were mostly women. Regarding radiological findings, sinusitis was significantly seen in men (18.18% vs 3.61%). Among laboratory data, females significantly had higher erythrocyte sedimentation rate levels than males (21.66 ± 24.39 vs 9.60 ± 8.55). This study indicates that among CVST patients, men have significantly higher occurrences of sinusitis, and higher levels of erythrocyte sedimentation rate were observed in women. However, no other significant differences were found. More extensive studies are essential to fully comprehend the sex-specific aspects of CVST.

Background: Sexual function is a part of sexual health which is an important aspect of the quality of life. Physical activity is one of the healthiest activities that can effectively reduce the risk of sexual disorders. Therefore, this study was conducted with the aim of evaluating the effect of yoga and pelvic floor muscle exercises on the sexual function and sexual self-esteem of reproductive-age women. Methods: This randomized clinical trial study was conducted from September to December 2023 on 46 women of reproductive age working in the Shahrekord University of Medical Sciences and its affiliated health centers. Multi-stage cluster sampling was used to select the subjects; later, they were randomly divided into two intervention groups A (N=21) and B (N=25). Participants in intervention groups A and B performed pelvic floor muscle exercises at home using an educational pamphlet 3 times a week for 6 weeks, with 3 times a day repetition. In addition, women in the intervention group A participated in a yoga training program for 2 sessions per week for 6 weeks. Data collection tools included a demographic information form, the Female Sexual Function Index, and Sexual Self-Esteem Inventory for women. Questionnaires were completed by both groups before, immediately, and one month after the intervention. The data were analyzed using the chi-square test, fisher's exact test, independent two-sample t-test, repeated measures test, and analysis of covariance in SPSS software version 16. A significance level of less than 0.05 was considered. Results: The results showed no statistically significant difference between the two groups in sexual function (P=0.21) and sexual self-esteem (P=0.22) scores before the intervention. Also, the results showed no statistically significant difference between the two groups in terms of sexual function (P=0.35) and sexual self-esteem (P=0.59) scores one month after the intervention. However, the mean score of the sexual function index immediately after intervention showed a statistically significant difference between the intervention groups A (31.43±3.76) and B (29.41±2.38) (P<0.001). The mean score of the sexual self-esteem immediately after the intervention showed a statistically significant difference between the intervention groups A (181.19±19.90) and B (171.32±15.02) (P<0.001). Conclusion: Adding yoga exercises to pelvic floor muscle exercises can improve the sexual function and sexual self-esteem of women at their reproductive age.

Proficiency in medical writing is crucial for disseminating reports of medical studies. The impact of workshops in this regard on participants' confidence is a subject of debate. We assessed the impact of a hands-on workshop on participants' confidence in medical writing. Participants of a 2-day "learning-by-doing" workshop held at McMaster University participated in this before-after study. We used a unique, reliable, and valid tool comprising two domains of confidence in medical writing and using English language before and after receiving the educational intervention. Of 25 participants, 21 completed the instrument before and after the workshop. Typical participants were female, and students in their 30s, who had not attended a prior workshop. The mean (95% CI) increase in the participants' confidence for domain 1 was 15.3 (10.5, 20.1), for domain 2 was 16.8 (9.8, 23.8), and for the total score was 32.1 (20.9, 43.2) (all P<0.001). Between-subgroup analyses showed the score increase was significantly higher in participants with less than 5 years of experience in medical research. The workshop had a positive impact on enhancing participants' confidence in writing skills, including using active verbs, crafting short sentences, summarizing main findings, and adhering to checklists like CONSORT. Hands-on medical writing workshops can boost participants' confidence in writing medical articles and using optimal English language. Targeting junior researchers and graduate students could result in a better outcome. Emphasizing the writing areas where participants achieved higher score changes might yield better outcomes for such workshops.

INTRODUCTION: In recent years, several studies have reported on the relationship between diabetes and carpal tunnel syndrome (CTS). However, due to their contradictory results, a systematic review and meta-analysis were conducted to investigate this subject. METHODS: This study is a systematic review and meta-analysis of studies published in ISI Web of Science, Scopus, PubMed, Cochrane, Google Scholar, and Embase databases. Heterogeneity in the studies included in the meta-analysis was evaluated using statistical tests such as the Chi-square test, I2, and forest plots. Publication bias was assessed using Begg's and Egger's tests. RESULTS: This investigation analyzed data from 42 studies conducted between 1985 and 2022, with a total of 3,377,816 participants. The meta-analysis demonstrated that the odds ratio (OR) of CTS in participants with a history of diabetes compared to those without was 1.90 (95% CI: 1.64-2.21; P-value < 0.001). Given that publication bias was observed in this study (Begg's test P-value = 0.01), the modified OR was calculated with consideration of missed studies, which was 1.68 (95% CI: 1.45-1.94; P-value < 0.001). CONCLUSION: The results of this study suggest that diabetic patients have 90% higher odds of developing CTS compared to non-diabetic individuals, which is statistically significant.

BACKGROUND: The popularity of medical writing workshops highlights the need for a standard measurement tool to assess the impact of such workshops on participants' confidence in: 1- writing a standard article and 2- using optimal English language. Because such an instrument is not yet available, we undertook this study to devise and evaluate the first measurement tool to assess such confidence. METHOD: We created an item pool of 50 items by searching Medline, Embase, and Clarivate Analytics to find related articles, using our prior experience, and approaching the key informants. We revised and edited the item pool, and redundant ones were excluded. Finally, the 36-item tool comprised two domains. We tested it in a group of workshop applicants for internal consistency and temporal reliability using Cronbach's α and Pearson correlations and for content and convergent validity using the content validity index and Pearson correlations. RESULTS: The participants had a mean age of 40.3 years, a female predominance (74.3%), and a majority of faculty members (51.4%). The internal consistency showed high reliability (> 0.95). Test-retest reliability showed very high correlations (r = 0.93). The CVI for domain 1 was 0.78, for domain 2 was 0.73, and for the entire instrument was 0.75. CONCLUSION: This unique, reliable, and valid measurement tool could accurately measure the level of confidence in writing a standard medical article and in using the appropriate English language for this purpose.

OBJECTIVE: Anemia is a common condition in end-stage renal disease (ESRD) patients. Erythropoiesis-stimulating agents (ESAs) are commonly used to treat anemia in these patients. However, concerns have been raised regarding their potential effects on blood pressure. This systematic review and meta-analysis aim to investigate the relationship between ESAs and changes in systolic and diastolic blood pressure in hemodialysis patients. METHOD: This study is a systematic review and meta-analysis based on clinical trial studies published in various databases, including Web of Science, Cochrane Library, Science Direct, PubMed, Embase, Scopus, and Google Scholar, between 1980 and the end of 2022. We evaluated the quality of articles using the Jadad scale checklist and analyzed the data using Stata 15 software. RESULTS: Our meta-analysis included 34 clinical trial studies. The results showed a significant increase in both systolic blood pressure (SBP) and diastolic blood pressure (DBP) after the consumption of ESAs compared to before consumption. The mean difference in SBP was 4.84mmHg (95% CI: 2.74-6.94; p-value<0.001) and in DBP was 4.69mmHg (95% CI: 2.67-6.71; p-value<0.001). No publication bias was observed. Our meta-regression analysis showed that sample size, quality assessment score, and geographical location of the study were significant factors related to observed heterogenicity in to mean difference of SBP (p-value≤0.20). For DBP, the sample size, quality assessment score and follow-up duration were significant variables (p-value≤0.20). CONCLUSION: Based on the findings of our study, it appears that receiving ESAs is associated with a significant increase in both SBP and DBP in hemodialysis patients, with an increase of about 5mmHg.

Introduction: Prior studies on the association between erythropoiesis-stimulating agents (ESAs) and cardiovascular mortality in hemodialysis patients have yielded conflicting findings. We aimed to clarify this relationship through a systematic review and meta-analysis of current evidence. Methods: We comprehensively searched major databases for observational and interventional studies on ESA use and cardiovascular mortality in hemodialysis patients published from 1980 to September 2023. Pooled risk ratios (RR) with 95 % confidence intervals (CI) were calculated using random-effects models. Sources of heterogeneity were explored through subgroup analyses and meta-regression. The study data were analyzed using Stata 15 software. Findings: Upon conducting the initial search, we extracted 792 articles and, after screening and considering the research criteria, 17 studies with 372,156 participants were included in the meta-analysis. Overall, ESA use was associated with a 27 % increased risk of cardiovascular mortality (RR 1.27, 95 % CI: 1.15-1.40, p < 0.001). This risk varied by geographical location, with RRs of 1.27 (95 % CI: 1.14-1.41; p-value≤0.001) for America, 1.33 (95 % CI: 1.12-1.58; p-value = 0.001) for Asia, and 1.23 (95 % CI: 1.02-1.49; p-value = 0.028) for Europe. Importantly, a gender disparity was revealed, with studies involving a higher proportion of males showing greater risks (RR 1.51, 95 % CI: 1.25-1.83, p < 0.001) than female-predominant studies (RR 1.08, 95 % CI: 0.86-1.36, p < 0.001). Conclusion: Our meta-analysis indicates ESA use is associated with heightened cardiovascular mortality in hemodialysis patients, especially in males. These findings have implications for optimizing dosing strategies while balancing efficacy and safety. Further research is warranted, particularly randomized controlled trials, to establish definitive ESA dosing guidelines.
ABSTRACT
BACKGROUND: In recent years, various studies have been conducted to investigate the relationship between erythropoiesis-stimulating agents (ESAs) and mortality in hemodialysis patients, who showed contradictory results. Therefore, this study aimed to investigate the relationship between ESAs and mortality in hemodialysis patients. METHODS: The current study is a systematic review and meta-analysis based on observational and interventional studies published in the Web of Science, Cochrane Library, Science Direct, PubMed, Scopus, and Google Scholar databases between 1980 and the end of 2022. Jadad scale checklist and Newcastle Ottawa scale were used to evaluate the quality of articles. The study data were analyzed using Stata 15 software. RESULTS: In the initial search, 3933 articles were extracted, and by screening and considering the research criteria, 68 studies were finally included in the meta-analysis. According to the meta-analysis results, the risk ratio (RR) of overall mortality in hemodialysis patients receiving ESAs was equal to 1.19 (95% CI: 1.16-1.23, P ≤ 0.001). The RR of mortality in patients aged 60 years and under was equal to 1.33 (1.15-1.55, P ≤ 0.001), in the age group over 60 years was equal to 1.13 (1.10-1.16, P ≤ 0.001), in randomized clinical trial studies was equal to 1.06 (0.80-1.40, P = 0.701), in cohort studies was equal to 1.20 (1.16-1.25, P ≤ 0.001), in American countries was equal to 1.19 (1.10-1.29, P ≤ 0.001), in Asian countries was equal to 1.15 (1.10-1.19, P ≤ 0.001), and in European countries was equal to 1.18 (1.05-1.34, P = 0.007). CONCLUSION: The results of the study show that receiving ESAs is associated with a 19% increase in the risk of overall mortality in hemodialysis patients.

Aim: This study was devoted to determining the role of social support and socioeconomic factors in predicting students' depression. Methods: In this cross-sectional study, all first-year undergraduate students in the Shahrekord University of Medical Sciences, Iran, during the 2019-2020 academic year were included via the census method. Data collection tools include a researcher-made checklist about demographic and socioeconomic status, a standard questionnaire of perceived social support, and Beck's depression questionnaire. Smoothly clipped absolute deviation (SCAD) linear regression was used to model the role of social support and socioeconomic factors in predicting depression. Results: Out of the 220 first-year undergraduate students, 174 (79.1%) were female, and 176 (80.0%) were single. The mean ± SD of depression score among the first-year undergraduate students was 10.56 ± 5.19, and the mean ± SD of social support score was 48.86 ± 5.46. The mean score of depression was significantly higher in female students than in males (11.09 versus 8.59, P = 0.001) but was not statistically significant in different categories of age (P = 0.70), marital status (P = 0.37), ethnicity (P = 0.10), parents' education, and the other demographic variables. Pearson's correlation showed an inverse and significant correlation between depression and social support (R = -0.20, P = 0.003). The mean score of depression was at the highest level for students of public health and environmental health majors and was the lowest for students of laboratory sciences, which was statistically significant (P < 0.001). After adjusting the other variables, SCAD regression showed that social support plays a key role in depression prediction, and increasing social support leads to a decrease in depression score. Conclusion: Considering the existence of an inverse and significant correlation between depression and social support, any intervention to promote social support for first-year undergraduate students may decrease depression.
ABSTRACT
Background: Academic satisfaction is known as one of the most important factors in increasing students' efficiency, and academic burnout is one of the most significant challenges of the educational system, reducing student motivation and enthusiasm. Clustering methods try to categorize individuals into a number of homogenous groups. Aims: To cluster undergraduate students at Shahrekord University of Medical Sciences based on academic burnout and satisfaction with their field of study. Materials and Methods: The multistage cluster sampling method was used to select 400 undergraduate students from various fields in 2022. The data collection tool included a 15-item academic burnout questionnaire and a 7-item academic satisfaction questionnaire. The average silhouette index was used to estimate the number of optimal clusters. The NbClust package in R 4.2.1 software was used for clustering analysis based on the k-medoid approach. Results: The mean score of academic satisfaction was 17.70 ± 5.39, while academic burnout averaged 37.90 ± 13.27. The optimal number of clusters was estimated at two based on the average silhouette index. The first cluster included 221 students, and the second cluster included 179 students. Students in the second cluster had higher levels of academic burnout than the first cluster. Conclusion: It is suggested that university officials take measures to reduce the level of academic burnout through academic burnout training workshops led by consultants to promote the students' interests.

Background: Current evidence in low back pain (LBP) focuses on population averages and traditional multivariate analyses to find the significant difference between variables. Such a focus actively obscured the heterogeneity and increased errors. Cluster analysis (CA) addresses the mentioned shortcomings by calculating the degree of similarity among the relevant variables of the different objects. Objective: This study aims to evaluate the agreement between the treatment-based classification (TBC) system and the equivalent 3 cluster typology created by partitioning around medoids (PAM) analysis. Material and Methods: In this cross-sectional study, a convenient sample of 90 patients with low back pain (50 males and 40 females) aged 20 to 65 years was included in the study. The patients were selected based on the 21 criteria of 2007 TBC system. An equivalent 3 cluster typology (C3) was applied using PAM method. Cohen's Kappa was run to determine if there was agreement between the TBC system and the equivalent C3 typology. Results: PAM analysis revealed the evidence of clustering for a C3 cluster typology with average Silhouette widths of 0.12. Cohen's Kappa revealed fair agreement between the TBC system and C3 cluster typology (Percent of agreement 61%, Kappa=0.36, P<0.001). Selected criteria by PAM analysis were different with original TBC system. Conclusion: Higher probability of chance agreement was observed between two classification methods. Significant inhomogeneity was observed in subgroups of the 2007 TBC system.
ABSTRACT
BACKGROUND: Cardiac surgery is performed worldwide to treat severe cases of cardiovascular diseases. Statins have shown controversial effects on complications after cardiac surgeries. We aimed to investigate the effect of preoperative statin therapy on the frequency of postoperative mortality, renal, and neurological complications. METHODS: In a retrospective cohort study, the database of patients operated on in two hospitals in southern Iran during 2008-2019 was used to compare preoperative statin use with no use on the composite outcome of mortality, renal, and neurological complications as well as on each component of the composite, separately. Effects of low dose (<40 mg simvastatin equivalence) vs. high dose (≥40 mg) statins were also evaluated. Confounders that could affect the outcomes were considered in the logistic regression model, and multiple imputation techniques were used to categorize patients with unknown statin dose use as either high or low-dose users. RESULTS: Of total 7329 patients, 17.6% of statin users and 17% of non-statin users developed the composite outcome (P=0.51). Statin use had no statistically significant association with the composite outcome (aRR 1.01 [95% CI: 0.88-1.16]). There was no significant association with mortality [aRR: 0.75 (95% CI: 0.34-1.69)], neurological [aRR: 1.25 (95% CI: 0.77-2.12)], or renal complications [aRR: 1.03 (95% CI 0.90-1.19)] after surgery. Neither low nor high doses had any statistically significant effect on the composite or any of its components. CONCLUSIONS: In this large study, preoperative statin use, either high dose or low dose, did not affect short-term postoperative mortality, neurological, or renal complications.

BACKGROUND: Recurrent aphthous stomatitis (RAS) is one of the most common oral mucosa diseases. This study aimed to investigate the association of RAS with general health and oral health-related quality of life among dental students of Shahrekord University of Medical Sciences in 2020. METHODS: In this cross-sectional study, a researcher-made checklist about the type, size, location, number, and recurrence rate of ulcers, oral health-related quality of life questionnaire (OHIP-14), and a 28-item general health questionnaire (GHQ-28) were completed by 100 dental students. RESULTS: The proportion of RAS was significantly higher among females than males (61.1 versus 38.9, P=0.03) and was associated with family involvement history (P<0.001) and a Tendency to eat spicy foods (P=0.02). Moreover, the oral health-related quality of life was significantly lower among students with a history of RAS (8.17 ± 8.33 versus 4.22 ± 4.10, P=0.003). The results showed that GHQ-positive status was significantly associated with ulcer size (P=0.01). The general health status was positively correlated with RAS prevalence (p=0.04). Also, an investigation of the OHIP questionnaire showed that there was a significant correlation between physical status (r=0.31, P<0.001), insomnia, and mental status (r=0.33, P<0.001) with OHIP total score. CONCLUSION: The results of this study confirmed a significant association between aphthous stomatitis and general health and oral health-related quality of life. So possibly improving general health and oral health-related quality of life may be effective in preventing aphthous stomatitis.
ABSTRACT
BACKGROUND: Although Movement System Impairment (MSI) model classifies patients with knee impairments, it has some limitations. This study compares MSI model with a new Partitioning Around Medoids (PAM) model in knee pain patients. METHODS: In this cross-sectional study, knee movement impairments (signs) and symptoms. (pain) of 200 patients were studied in eight different functional positions. After modification of impairments, the examinations were repeated to record the changes in symptoms. The patients were then classified based on the signs and symptoms firstly by MSI model and secondly using PAM clustering by R software. RESULTS: PAM model has a similar acceptable grouping compared to MSI because most patients are in 4 similar categories in both methods: valgus, varus, hyperextension and hypomobility. However, due to low discriminative power of the tests used for finding hypermobility and patellar dysfunctions, these sub-clusters are absent in PAM model. Instead, two new sub-clusters of self-management and valgus with hypomobility were found. Most importantly, the PAM model sorted the signs and symptoms based on their discriminative power and eliminated trivial tests so that the therapist can classify patients more quickly by performing clinically relevant tests. CONCLUSION: The new PAM method can be advantageous for therapists since it defines the importance of signs over symptoms in examination, prioritizes examination tests, and outlines tests with lower discriminative power. In PAM model, patients in the hypermobility and patellar subgroups of MSI model merged into other sub-clusters due to low discriminating power of their characteristics.
