The comparison of the effect of non-pharmacological pain relief and pharmacological analgesia with remifentanil on fear of childbirth and postpartum depression: a randomized controlled clinical trial.

INTRODUCTION: Childbirth may be associated with psychological, social, and emotional effects and provide the background for women's health or illness throughout their life. This research aimed at comparing the impact of non-pharmacological pain relief and pharmacological analgesia with remifentanil on childbirth fear and postpartum depression. MATERIALS AND METHOD: This randomized clinical trial with two parallel arms was conducted on 66 women with term pregnancy referred to Taleghani Hospital in Tabriz for vaginal delivery during September 2022 to September 2023. First, all of the eligible participants were selected through Convenience Sampling. Then, they were randomly assigned into two groups of pharmacological analgesia with remifentanil and non-pharmacological analgesia with a ratio of 1:1 using stratified block randomization based on the number of births. Before the intervention, fear of childbirth (FOC) was measured using Delivery Fear Scale (DFS) between 4 and 6 cm cervical dilatation. Pain and fear during labor in dilatation of 8 cm were measured in both groups using VAS and DFS. After delivery, FOC was assessed using Delivery Fear Scale (W DEQ Version B) and postpartum depression using the Edinburgh's postpartum depression scale (EPDS). Significance level was considered 0.05. Mean difference (MD) was compared with Independent T-test and ANCOVA pre and post intervention. RESULTS: The mean score of FOC in the non-pharmacological analgesia group was significantly lower than that in the pharmacological analgesia group after the intervention by controlling the effect of the baseline score (MD: -6.33, 95%, Confidence Interval (CI): -12.79 to -0.12, p = 0.04). In the postpartum period, the mean score of FOC in the non-pharmacological analgesia group was significantly lower than that in the pharmacological analgesia group after controlling the effect of the baseline score (MD: -21.89; 95% CI: -35.12 to -8.66; p = 0.002). The mean score of postpartum depression in the non-pharmacological analgesia group was significantly lower than that in the pharmacological analgesia group (MD: -1.93, 95% CI: -3.48 to -0.37, p = 0.01). TRIAL REGISTRATION: Iranian Registry of Clinical Trials (IRCT): IRCT20170506033834N10. Date of registration: 05/07/2022 Date of first registration: 05/07/2022. URL: https://www.irct.ir/trial/61030; Date of recruitment start date05/07/2022. CONCLUSION: The study results indicated a reduction in FOC and postpartum depression among parturient women receiving non-pharmacological strategies with active participation in childbirth compared to women receiving pharmacological analgesia. Owing to the possible side effects of pharmacological methods for mother and fetus, non-pharmacological strategies with active participation of the mother in childbirth are recommended to reduce the FOC and postpartum depression.

Validation and measurement properties of the Male and Female Fertility Knowledge Inventories (MFKI and FFKI) in Iranian couples.

BACKGROUND: One of the most important population challenges during the last three decades has been the significant decrease in the fertility rate worldwide. Since the validity and reliability of the Male and Female Fertility Knowledge Inventories (MFKI and FFKI) have not been determined in Iran, we conducted this study to assess psychometric characteristics of the MFKI and FFKI in couples in Tabriz and Urmia, Iran. METHODS: This was a cross-sectional study, as the first part (quantitative phase) of a sequential explanatory mixed-method study. The current study was done on 1200 participants (600 women with their husbands) living in the northwestern region of Iran, between January 2023 and September 2023. The psychometric properties of the Persian version of the tool (MFKI and FFKI) were performed in 5 stages, including translation process, content validity, face validity, construct validity and reliability assesment. RESULTS: In this study, the CVI, CVR, and impact scores of the MFKI tool were equal to 0.90, 0.88, 3.26 and CVI, CVR, and Impact scores of the FFKI tool were respectively equal to 0.95, 0.91 and 3.59, that it indicated a satisfactory level of content and face validity. Then, to check the construct validity, the results of the exploratory factor analysis of the MFKI tool on 13 items led to the identification of 3 factors, including Environment and reproductive health (ERH), Lifestyle factors (LSF) and Sperm quality (SQ), which explained 66% of the cumulative variance. The results of the exploratory factor analysis of the FFKI tool on 15 items led to the identification of 4 factors, including Reproductive health (RH), Lifestyle factors (LSF), Chance of conception (CHC) and Ovarian reserve and preservation (ORP), which explained 68% of the cumulative variance. CONCLUSIONS: The findings of this study indicated that the Persian version of MFKI and FFKI has acceptable psychometric properties to measure the awareness of Iranian couples regarding fertility, which can be used as a screening tool for fertility knowledge by health care professionals and also as a reliable tool in research.

The right to sexual and reproductive health (SRH) is considered one of the basic rights of couples all over the world. Increasing childbearing age is a global social issue. In spite of the policies of having children in the previous decade, fertility reduction and involuntary childlessness are still the foremost global health problems. The fertility rate in Iran has reduced significantly in the last thirty years. This reduction can be attributed not only to economic difficulties but also to the postponement of marriage and having children, as well as infertility issues, which, by increasing the awareness of couples about fertility, seems to be able to overcome this problem to some extent. Consequently, we decided to conduct this study with the aim of determining the psychometric properties of the Male and Female Fertility Knowledge Inventories (MFKI and FFKI) in Iranian couples. The results of the current study revealed that this questionnaire, having acceptable psychometric properties to evaluate the state of awareness of Iranian couples regarding fertility, can be used as a valid and reliable tool in Iranian couples. It appears that it is essential for health care providers to play an active role in advising couples about the appropriate age of fertility, the problems of delay in having children, overcoming the value of having few children in society. Accordingly, health policymakers should recommend the use of valid screening tools to identify the knowledge of women and men about fertility in health centers.

A randomized clinical trial: Efficacy of group-based acceptance and commitment therapy program for breast cancer patients with high fear of progression.

BACKGROUND: Fear of progression (FOP) is a common and significant concern among cancer patients, encompassing worries about cancer progression during active treatment. Elevated levels of FOP can be dysfunctional. This study aims to assess the efficacy of an Acceptance and Commitment Therapy (ACT)-based intervention on FOP, anxiety sensitivity (AS), and quality of life (QOL) in breast cancer patients. METHODS: A clinical trial was conducted involving 80 stage I-III active-treatment breast cancer patients with a score greater than 34 on the Fear of Progression Questionnaire-Short Form scale. These patients were randomly assigned in a 1:1 ratio to either an intervention group, which received weekly 70-min sessions of 5-ACT-bsed group-therapy, or a control group that received usual treatment. Variables including FOP, AS, QOL, and ACT-related factors were assessed using ASQ, QLQ-C30, Cognitive Fusion Questionnaire, and Acceptance and Action Questionnaire-II at three time points: baseline, post-intervention, and 3-month follow-up. The efficacy of the intervention was evaluated using mixed model analysis across all time-points. RESULTS: The fidelity and acceptability of the ACT-based manual were confirmed using significant methods. A significant reduction in FOP was observed only in the ACT group at post-intervention (P-valueACT < 0.001; Cohen dACT = 1.099). Furthermore, the ACT group demonstrated a more significant reduction in FOP at follow-up. Furthermore, all secondary and ACT-related variables, except for the physical symptoms subscale, showed significant improvement in the ACT group compared to the control group. CONCLUSIONS: Our ACT-based manual showed promise for reducing FOP, AS, and improving QOL, and ACT-related variables in breast cancer patients 3 months following the intervention.

A Human Homozygous HELQ Missense Variant Does Not Cause Premature Ovarian Insufficiency in a Mouse Model.

Disruption of meiosis and DNA repair genes is associated with female fertility disorders like premature ovarian insufficiency (POI). In this study, we identified a homozygous missense variant in the HELQ gene (c.596 A>C; p.Gln199Pro) through whole exome sequencing in a POI patient, a condition associated with disrupted ovarian function and female infertility. HELQ, an enzyme involved in DNA repair, plays a crucial role in repairing DNA cross-links and has been linked to germ cell maintenance, fertility, and tumour suppression in mice. To explore the potential association of the HELQ variant with POI, we used CRISPR/Cas9 to create a knock-in mouse model harbouring the equivalent of the human HELQ variant identified in the POI patient. Surprisingly, Helq knock-in mice showed no discernible phenotype, with fertility levels, histological features, and follicle development similar to wild-type mice. Despite the lack of observable effects in mice, the potential role of HELQ in human fertility, especially in the context of POI, should not be dismissed. Larger studies encompassing diverse ethnic populations and alternative functional approaches will be necessary to further examine the role of HELQ in POI. Our results underscore the potential uncertainties associated with genomic variants and the limitations of in vivo animal modelling.

Predicting mortality and recurrence in colorectal cancer: Comparative assessment of predictive models.

Introduction: Colorectal cancer (CRC), also known as colorectal cancer, is a significant disease marked by high fatality rates, ranking as the third leading cause of global mortality. The main objective of this study was to assess the accuracy of predictive models in predicting both mortality events and the probability of disease recurrence. Method: A retrospective analysis was conducted on a cohort of 284 individuals diagnosed with colorectal cancer between 2001 and 2017. Demographic and clinical data, including gender, disease stage, age at diagnosis, recurrence status, and treatment details, were meticulously recorded. We rigorously evaluated various predictive models, including Decision Trees, Random Forests, Random Survival Forests (RSF), Gradient Boosting, mboost, Deep Learning Neural Network (DLNN), and Cox regression. Performance metrics, such as sensitivity, positive predictive value (PPV), specificity, area under the receiver operating characteristic curve (ROC area), and overall accuracy, were calculated for each model to predict mortality and disease recurrence. The analysis was performed using R version 4.1.3 software and the Python programming language. Results: For mortality prediction, the mboost model demonstrated the highest sensitivity at 96.9% (95% CI: 0.83-0.99) and an ROC area of 0.88. It also exhibited high specificity at 80% (95% CI: 0.59-0.93), a positive predictive value of 86.1% (95% CI: 0.70-0.95), and an overall accuracy of 89% (95% CI: 0.78-0.96). Random Forests showed perfect sensitivity of 100% (95% CI: 0.85-1) but had low specificity at 0% (95% CI: 0-0.52) and poor overall accuracy (50%). On the other hand, DLNN had the lowest performance metrics for mortality prediction, with a sensitivity of 24% (95% CI: 0.222-0.268), specificity of 75% (95% CI: 0.73-0.77), and a lower positive predictive value of 42% (95% CI: 0.38-0.45). The Gradient Boosting model showed the best performance in predicting recurrence, achieving perfect sensitivity of 100% (95% CI: 0.87-1) and high specificity at 92.9% (95% CI: 0.76-0.99). It also had a high positive predictive value of 93.3% (95% CI: 0.77-0.99). Gradient Boosting, with an ROC area of 96.4%, and mboost, with an ROC area of 75%, demonstrated remarkable performance. DLNN had the lowest performance metrics for recurrence prediction, with sensitivity at 1.75% (95% CI: 0.01-0.02), specificity at 98% (95% CI: 0.97-0.98), and a lower positive predictive value at 52.6% (95% CI: 0.39-0.65). Conclusion: In summary, the mboost model demonstrated outstanding performance in predicting mortality, achieving exceptional results across various evaluation metrics. Random Forests exhibited perfect sensitivity but showed poor specificity and overall accuracy. The DLNN model displayed the lowest performance metrics for mortality prediction. In terms of recurrence prediction, the Gradient Boosting model outperformed other models with perfect sensitivity, high specificity, and positive predictive value. The DLNN model had the lowest performance metrics for recurrence prediction. Overall, the results emphasize the effectiveness of the mboost and Gradient Boosting models in predicting mortality and recurrence in colorectal cancer patients.

Development and Psychometric Assessment of "Self-Efficacy Scale" for Patients With Beta Thalassemia Major: A Mixed-Methods Study.

Background and Purpose: Since self-efficacy is a significant factor influencing the self-management of chronic diseases, including thalassemia major, it is considered a key concept in chronic diseases. This study aimed to develop and psychometrically evaluate the self-efficacy scale for patients with thalassemia major. Methods: This was a mixed-methods study conducted in two phases. In phase 1, a qualitative study with a conventional content analysis design was conducted. In phase 2, which was a quantitative one, the psychometric analysis of the instrument's phrases was done. Results: The instrument has 35 items and 3 factors. The Cronbach's alpha coefficient and the intraclass correlation coefficient were .93 and .94, respectively. Conclusions: This study confirms the validity and reliability of the Beta Thalassemia Major Self-Efficacy Scale. With this tool, nurses can evaluate the self-efficacy of patients with thalassemia major.

Translation and measurement properties of pregnancy and childbirth questionnaire in Iranian postpartum women.

BACKGROUND: Perceived care quality and patient satisfaction have been important care quality indicators in recent decades, and healthcare professionals have been influential on women's childbirth experience. This study investigated the measurement properties of the Persian version of the Pregnancy and Childbirth Questionnaire (PCQ), designed to measure mothers' satisfaction with the quality of healthcare services provided during pregnancy and childbirth. METHODS: This is a cross-sectional methodological study. Instrument translation, face validity, content validity, structural validity, and reliability evaluation were performed to determine the measurement properties of the PCQ's Persian version. A backward-forward approach was employed for the translation process. Impact scores were selected based on the items' importance to measure face validity. Content validity index (CVI) and content validity ratio (CVR) were calculated to measure content validity, and exploratory and confirmatory factor analyses were used to measure structural validity. The cluster random sampling method was used, resulting in a sample of 250 eligible women referred to the health centers of Tabriz, Iran, who were 4 to 6 weeks after giving birth. Cronbach's alpha coefficient and Intraclass Correlation Coefficient (ICC) using a test-retest approach were used to determine the questionnaire's reliability. RESULTS: The impact scores of all items were above 1.5, which indicates a suitable face validity. The content validity was also favorable (CVR = 0.95, CVI = 0.90). Exploratory factor analysis on 25 items led to the removal of item 2 due to a factor loading of less than 0.3 and the extraction of three factors explaining 65.07% of the variances. The results of the sample adequacy size were significant (< 0.001, and Kaiser-Meyer-Olkin = 0.886). The model's validity was confirmed based on the confirmatory factor analysis fit indicators (i.e., RMSEA = 0.08, SRMR = 0.09, TLI = 0.91, CFI = 0.93, x2/df = 4.65). The tool's reliability was also confirmed (Cronbach's alpha = 0.88, and ICC (95% CI) = 0.93 (0.88 to 0.95)). CONCLUSION: The validity and reliability of the PCQ's Persian version were suitable to measure the extent to which Iranian women are satisfied with the quality of prenatal and intrapartum care.

Effects of dried okra extract on lipid profile, renal function and some RAGE-related inflammatory genes expression in patients with diabetic nephropathy: A randomized controlled trial.

BACKGROUND: Diabetic nephropathy (DN) is a common complication of type 2 diabetes. Okra (Abelmoschus esculentus L) is reported to have anti-diabetic effects. The present study aimed to investigate the effects of dried okra extract (DOE) supplementation on lipid profile, renal function indices, and expression of inflammatory genes, as well as serum level of soluble Receptor for Advanced glycation end products (sRAGE) in patients with DN. METHODS: In this triple-blind randomized placebo-controlled clinical trial, 64 eligible patients with DN received either 125 mg of DOE or placebo daily along with DN-related nutritional recommendations for 10 weeks. Changes in kidney indices including proteinuria and estimated glomerular filtration rate (eGFR), lipid profile, serum SRAGE, as well as the expression of RAGE, ICAM-1, and IL-1 genes were measured over 10 weeks. RESULTS: After adjustment for the potential confounders, between-group analyses showed no significant differences in terms of lipid profile, kidney function indices, sRAGE, and RAGE-related inflammatory genes expression after 10 weeks. CONCLUSION: Daily 125 mg DOE along with nutritional recommendations on top of usual care did not lead to significant changes in renal function indices, lipid profile, and inflammatory genes expression in patients with DN.

Unraveling atherosclerotic cardiovascular disease risk factors through conditional probability analysis with Bayesian networks: insights from the AZAR cohort study.

This study aimed at modelling the underlying predictor of ASCVD through the Bayesian network (BN). Data for the AZAR Cohort Study, which evaluated 500 healthcare providers in Iran, was collected through examinations, and blood samples. Two BNs were used to explore a suitable causal model for analysing the underlying predictor of ASCVD; Bayesian search through an algorithmic approach and knowledge-based BNs. Results showed significant differences in ASCVD risk factors across background variables' levels. The diagnostic indices showed better performance for the knowledge-based BN (Area under ROC curve (AUC) = 0.78, Accuracy = 76.6, Sensitivity = 62.5, Negative predictive value (NPV) = 96.0, Negative Likelihood Ratio (LR-) = 0.48) compared to Bayesian search (AUC = 0.76, Accuracy = 72.4, Sensitivity = 17.5, NPV = 93.2, LR- = 0.83). In addition, we decided on knowledge-based BN because of the interpretability of the relationships. Based on this BN, being male (conditional probability = 63.7), age over 45 (36.3), overweight (51.5), Mets (23.8), diabetes (8.3), smoking (10.6), hypertension (12.1), high T-C (28.5), high LDL-C (23.9), FBS (12.1), and TG (25.9) levels were associated with higher ASCVD risk. Low and normal HDL-C levels also had higher ASCVD risk (35.3 and 37.4), while high HDL-C levels had lower risk (27.3). In conclusion, BN demonstrated that ASCVD was significantly associated with certain risk factors including being older and overweight male, having a history of Mets, diabetes, hypertension, having high levels of T-C, LDL-C, FBS, and TG, but Low and normal HDL-C and being a smoker. The study may provide valuable insights for developing effective prevention strategies for ASCVD in Iran.

Exploring the impact of stage and tumor site on colorectal cancer survival: Bayesian survival modeling.

Colorectal cancer is a prevalent malignancy with global significance. This retrospective study aimed to investigate the influence of stage and tumor site on survival outcomes in 284 colorectal cancer patients diagnosed between 2001 and 2017. Patients were categorized into four groups based on tumor site (colon and rectum) and disease stage (early stage and advanced stage). Demographic characteristics, treatment modalities, and survival outcomes were recorded. Bayesian survival modeling was performed using semi-competing risks illness-death models with an accelerated failure time (AFT) approach, utilizing R 4.1 software. Results demonstrated significantly higher time ratios for disease recurrence (TR = 1.712, 95% CI 1.489-2.197), mortality without recurrence (TR = 1.933, 1.480-2.510), and mortality after recurrence (TR = 1.847, 1.147-2.178) in early-stage colon cancer compared to early-stage rectal cancer. Furthermore, patients with advanced-stage rectal cancer exhibited shorter survival times for disease recurrence than patients with early-stage colon cancer. The interaction effect between the disease site and cancer stage was not significant. These findings, derived from the optimal Bayesian log-normal model for terminal and non-terminal events, highlight the importance of early detection and effective management strategies for colon cancer. Early-stage colon cancer demonstrated improved survival rates for disease recurrence, mortality without recurrence, and mortality after recurrence compared to other stages. Early intervention and comprehensive care are crucial to enhance prognosis and minimize adverse events in colon cancer patients.

The intention to leave among academics in Iran: an examination of their work-life quality and satisfaction.

BACKGROUND: Despite the importance of faculty retention, there is little understanding of how demographic variables, professional and institutional work-life issues, and satisfaction interact to explain faculty intentions to leave. This study aimed to investigate the intention to leave among academics and their Work-Life Quality and Satisfaction. METHODS: This is a descriptive cross-sectional study conducted by 8 faculties affiliated to Urmia University of Medical Sciences located in Urmia, West Azarbaijan province, Iran. The participants in the study were 120 faculty members from Nursing and Midwifery, Medicine, Allied health professions, and Health management and medical information faculties. The Work-Life Quality and Satisfaction scale, and the intension to leave scale were used for data collection. Uni- and multivariable linear regression analyses were employed to determine predictors of the intention to leave (P-values < 0.05). RESULTS: The mean scores of all dimensions of Work-Life Quality and Satisfaction scale, and intention to leave were in an average level. There is a negative correlation between Work-Life Quality and Satisfaction subscales, along with demographic factors, and the intention to leave (P < 0.05), while multivariate analysis showed that work experience and Discipline were significant independent predictors of intention to leave (P < 0.05). CONCLUSIONS: In order to improve education in universities, it is necessary to pay attention to the conditions of creating job satisfaction in academics. Considering the high intention to leave among Nursing lecturers, without sufficient support of nursing schools in terms of human resources, it may suffer by the lack of academic staff; eventually the quality of education will reduce in undergraduate nursing in the long term.

Association between healthy eating index-2015 scores and metabolic syndrome among Iranian women: a cross-sectional study.

BACKGROUND: Metabolic syndrome (MetS) is one of the leading public health issues in the world with a reported prevalence of nearly 25% in the past decades in Iran. The present research aimed to identify the association between the Healthy Eating Index (HEI) and MetS components among female teachers. METHODS: In this cross-sectional study, 97 female teachers aged 31-57 years were enrolled from 2018 to 2019 in Qom, Iran. Usual dietary intakes were assessed using a validated 168-item Food Frequency Questionnaire (FFQ). HEI-2015 was calculated according to the consumption of whole fruits, vegetables, protein foods, beans, seafood, plant proteins, total and refined grain, dairy, fatty acid ratio, saturated fats, added sugars, and sodium. We also measured anthropometric and biochemical parameters. To evaluate the association between HEI-2015 and MetS, multivariate logistic regression was performed. RESULTS: MetS was found in 59.8% of participants. Total HEI-2015 scores were significantly lower in participants with MetS compared to those without MetS (59.69 ± 8.98 vs. 64.21 ± 8.71, respectively; p = 0.02). Daily energy intake, weight, body mass index, waist circumference, systolic and diastolic blood pressure, serum triglyceride, and fasting blood sugar levels were higher in women with MetS (all p < 0.05). Higher HEI-2015 total scores (OR: 0.94; 95% CI: 0.89-0.99; p = 0.02) and scores of total vegetables (OR: 0.62; 95% CI: 0.42-0.91; p = 0.02), dark green vegetables and beans (OR: 0.62; 95% CI: 0.39-0.98; p = 0.04), fatty acid ratio (OR: 0.83; 95% CI: 0.68-0.99; p = 0.04), refined grain (OR: 0.86; 95% CI: 0.75-0.99; p = 0.04), and added sugars (OR: 0.44; 95% CI: 0.26-0.75; p = 0.002) were all associated with lower odds of having MetS. CONCLUSIONS: Higher HEI-2015 scores, particularly in total vegetables, dark green vegetables, beans, and fatty acid ratio, as well as refined grain and added sugars were found to be associated with reduced odds of having MetS among Iranian female teachers. However, further prospective studies are required to confirm this finding.

Intraoperative dexamethasone and chronic postsurgical pain: a propensity score-matched analysis of a large trial.

BACKGROUND: Dexamethasone has been shown to reduce acute pain after surgery, but there is uncertainty as to its effects on chronic postsurgical pain (CPSP). We hypothesised that in patients undergoing major noncardiac surgery, a single intraoperative dose of dexamethasone increases the incidence of CPSP. METHODS: We devised a propensity score-matched analysis of the ENIGMA-II trial CPSP dataset, aiming to compare the incidence of CPSP in patients who had received dexamethasone or not 12 months after major noncardiac surgery. The primary outcome was the incidence of CPSP. We used propensity score matching and inverse probability weighting to balance baseline variables to estimate the average marginal effect of dexamethasone on patient outcomes, accounting for confounding to estimate the average treatment effect on those treated with dexamethasone. RESULTS: We analysed 2999 patients, of whom 116 of 973 (11.9%) receiving dexamethasone reported CPSP, and 380 of 2026 (18.8%) not receiving dexamethasone reported CPSP, unadjusted odds ratio 0.76 (95% confidence interval 0.78-1.00), P=0.052. After propensity score matching, CPSP occurred in 116 of 973 patients (12.2%) receiving dexamethasone and 380 of 2026 patients (13.8%) not receiving dexamethasone, adjusted risk ratio 0.88 (95% confidence interval 0.61-1.27), P=0.493. There was no difference between groups in quality of life or pain interference with daily activities, but 'least pain' (P=0.033) and 'pain right now' (P=0.034) were higher in the dexamethasone group. CONCLUSIONS: Dexamethasone does not increase the risk of chronic postsurgical pain after major noncardiac surgery.

Quality of life amongst patients with diverting umbilical stomas in rectal surgery: a single centre prospective randomized controlled pilot study.

BACKGROUND: The umbilical stoma (umbistoma) has been proposed as a viable alternative site for a temporary defunctioning stoma. Suggested advantages of the umbistoma include decreased number of surgical incisions required, improved cosmesis and ease of reversal surgery. This study aimed to assess the patient experience of umbilical loop ileostomies in rectal surgery, with the primary outcome being patient reported quality of life (QoL). METHODS: A total of 20 patients undergoing laparoscopic rectal cancer surgery were randomly allocated to have a defunctioning ileostomy at a conventional site (right iliac fossa) or at the umbilicus. Patient-reported QoL was assessed at 6 weeks using the Stoma-QoL questionnaire. Secondary outcomes were number of stomas reversed, length of time awaiting stoma reversal surgery, duration of operative time for stoma reversal, length of hospital stay following stoma reversal and rate of parastomal or post reversal incisional hernias. RESULTS: Patients who had an umbilical stoma scored significantly lower on the Stoma-QoL questionnaire compared to the conventional group, particularly on questions regarding feelings of tiredness, body insecurity and anxiety. No significant differences were observed between the two groups in relation to secondary outcomes. CONCLUSION: There may be potential disadvantages to the umbilical stoma with negative impacts on body image and subsequent increased social anxiety. Patient selection and adequate counselling will be important when considering an umbilical stoma. Further larger scale prospective studies are required to further validate the feasibility and longer-term safety of umbilical stomas in both clinical outcomes as well as patient QoL.

Compensation based on work relative value unit for cardiovascular surgeons in Iran: A mixed method study.

BACKGROUND: Work relative value unit (wRVU) is a tool for assessing surgeons' performance, compensation, and productivity. It appears that wRVU for cardiovascular procedures does not consider complexity and its value for lengthy operations is low. The aim of the study is to determine wRVU for cardiovascular procedures in Iran according to the proposed approach. MATTERIALS AND METHODS: This study was conducted as a mixed method in teaching hospitals in Tabriz in the period of September 2020 to December 2021. According to Hospital Information System and expert opinions, six procedures in cardiovascular surgery were included in the study. They were compared with 18 procedures in neurosurgery, orthopedics, and otorhinolaryngology in terms of the operation time and wRVU/min. Then, we calculated new wRVUs for the selected procedures based on surgeons' opinions, time measurements, and anesthetists' points of view by content analysis in qualitative and statistical analysis in quantitative parts. RESULTS: Among the six cardiac procedures, the wRVU for five was under-estimated. The wRVU/min value ranged from 0/28 to 1/15 in the studied procedures. Findings demonstrate no significant relationship between the length of operations and the wRVU announced by the Ministry of Health and Medical Education (P value >0/05). Compared to studied procedures in four specialties, thoracoabdominal aortic aneurysm repair has the longest surgery time at 417 minutes. According to anesthesiologists, cardiovascular; orthopedics; ear, nose, and tongue; and neurosurgery specialties obtained 4/2, 2/9, 2/8, and 4, respectively, in terms of surgery duration, complexity, risk, and physical effort. CONCLUSION: Despite policymakers' attempts to bring justice to payments, it seems that there has been little progress in paying cardiovascular surgeons. Improper payment to cardiovascular surgeons will affect the future of the workforce in this specialty. Today, the need to reconsider the wRVUs in heart specialty is felt more than before.

Psychometric evaluation and cross-cultural adaptation of the Australian Pelvic Floor Questionnaire (APFQ-IR) in Iranian reproductive age women.

Pelvic floor disorders (PFDs), as a silent alert, is one of the pervasive debilitating health concerns among women all over the world, such that in developed countries, one in four women, suffers from PFDs. Validity and reliability of the Australian Pelvic Floor Questionnaire (APFQ) has not been determined in Iran, so to determine APFQ's psychometric characteristics, we decided to conduct this study on women of reproductive age in Tabriz city, Iran. This methodological cross-sectional study was intended to determine the psychometric properties of the Persian version of the APFQ-IR in 5 steps including "translation process, content validity, face validity, construct validity (exploratory and confirmatory factor analyses and examination of ceiling and floor effects) and reliability" on 400 reproductive age women referring to health centers in Tabriz city, Iran, with cluster random sampling method in the period between May 2022 to September 2022. The translation process was done based on two approaches, Dual panel, and Beaton et al.'s five steps. Then, in order to evaluate content validity, face validity, and construct validity, 10 instrument and PFDs experts, 10 women from the target group investigated the instrument's items, and 400 eligible women completed the instrument. Finally, to determine the reliability, two internal consistency methods, (Cronbach's alpha and McDonald's omega) and test-retest method (ICC) were used. In the present study, content validity assessment of APFQ-IR, showed a good level of validity (CVR = 0.96, CVI = 0.94). To assess construct validity, exploratory factor analysis results on 36 items, led to the identification of 4 factors including bladder function, bowel function, prolapse symptom and sexual function, which explained 45.53% of the cumulative variance and indicated the sufficiency of the sample size (Kaiser-Meyer-Olkin = 0.750). Implementing confirmatory factor analysis, (RMSEA = 0.08, SRMR = 0.08, TLI = 0.90, CFI = 0.93, χ2/df = 3.52) confirmed the model fit indices. Finally the internal consistency and reliability was high for the entire instrument (Cronbach's alpha = 0.85; McDonald's omega (95% CI) = 0.85 (0.83-0.87) and Intraclass Correlation Coefficient (95% CI) = 0.88 (0.74-0.94)). The Persian version of the APFQ-IR, has a good validity and reliability and has acceptable psychometric properties, thus can be used both for research purposes and for clinical evaluation of pelvic floor disorders symptoms in health centers.

The Effects of Coenzyme Q10 Supplementation on Oxidative Status and Lipid Profile in Migraine Patients: A Randomized Double-Blinded Controlled Clinical Trial.

Migraine is a common neurological disease correlated with oxidative stress and lipid profile disorders. The present study was designed to determine the effects of Coenzyme Q10 (Co-Q10) supplementation on oxidative status and lipid profile in migraine individuals. This clinical trial was conducted on 84 females aged 18-50 years, diagnosed for episodic migraine according to the International Headache Society. Subjects were randomized to receive either Co-Q10 supplement (400 mg/day) or placebo for 12 weeks. Lipid profile and oxidative stress indices including malondialdehyde (MDA) and total antioxidant capacity (TAC) were measured before and after intervention in both groups. Also, anthropometric indices, dietary intakes, and clinical features were collected. Data analysis was conducted using SPSS version 16. Seventy-seven of the participants, with mean age of 33.70 ± 7.75 years, completed the study. After 12-week intervention, Co-Q10 led to a significant decrease in MDA levels compared to placebo (p = 0.009), with no effect on TAC levels (p = 0.106). A significant increase in serum Co-Q10 concentration and high-density lipoprotein cholesterol (HDL-C) level in Co-Q10 group was observed, but no significant differences were found in other lipid profile variables (low-density lipoprotein cholesterol, triglycerides and total cholesterol). Among anthropometric variables, Co-Q10 only caused a significant reduction in body fat percentage (BFP), but we did not find any significant changes in others. A 12-week Co-Q10 supplementation led to significant improvement in clinical features, BFP, and HDL-C level among migraine individuals.

Predicting mortality in brain stroke patients using neural networks: outcomes analysis in a longitudinal study.

In this study, Neural Networks (NN) modelling has emerged as a promising tool for predicting outcomes in patients with Brain Stroke (BS) by identifying key risk factors. In this longitudinal study, we enrolled 332 patients form Imam hospital in Ardabil, Iran, with mean age: 77.4 (SD 10.4) years, and 50.6% were male. Diagnosis of BS was confirmed using both computerized tomography scan and magnetic resonance imaging, and risk factor and outcome data were collected from the hospital's BS registry, and by telephone follow-up over a period of 10 years, respectively. Using a multilayer perceptron NN approach, we analysed the impact of various risk factors on time to mortality and mortality from BS. A total of 100 NN classification algorithm were trained utilizing STATISTICA 13 software, and the optimal model was selected for further analysis based on their diagnostic performance. We also calculated Kaplan-Meier survival probabilities and conducted Log-rank tests. The five selected NN models exhibited impressive accuracy ranges of 81-85%. However, the optimal model stood out for its superior diagnostic indices. Mortality rate in the training and the validation data set was 7.9 (95% CI 5.7-11.0) per 1000 and 8.2 (7.1-9.6) per 1000, respectively (P = 0.925). The optimal model highlighted significant risk factors for BS mortality, including smoking, lower education, advanced age, lack of physical activity, a history of diabetes, all carrying substantial importance weights. Our study provides compelling evidence that the NN approach is highly effective in predicting mortality in patients with BS based on key risk factors, and has the potential to significantly enhance the accuracy of prediction. Moreover, our findings could inform more effective prevention strategies for BS, ultimately leading to better patient outcomes.

Psychometric Properties of the Persian Version of Cystic Fibrosis Questionnaire: Revised in Children with Cystic Fibrosis.

Background: Cystic fibrosis is a progressive, fatal disease affecting the quality of life. The cystic fibrosis questionnaire-revised (CFQ-R) is an efficient tool to monitor health-related quality of life in patients. The aim of this study was to explore the psychometric properties of the child and parent versions of the Persian version of the CFQ-R in the Iranian population. Methods: Fifty children with cystic fibrosis (6-11 years) and their parents were allocated in this methodological study to examine convergent validity, discriminant validity, test-retest reliability (n = 30), internal consistency, ceiling and floor effects, and agreement between two versions of the CFQ-R. Results: Convergent validity was confirmed for parent proxy (P < 0.05). CFQ-R discriminated patients among stages of disease severity based on lung function, age, and BMI (P < 0.05). Test-retest analysis revealed good to excellent reliability (inter-class correlation coefficient (ICC) = 0.78-0.97). In most domains, lower quality of life scores was obtained in the parent proxy compared to the child version (P < 0.05). Domain-specific correlations were found between the child version and parent proxy (P < 0.05). Internal consistency was generally confirmed (α = 0.13-0.83 in child version and α = 0.25-0.87 in parent proxy). There were no floor effects. Ceiling effects were mostly seen for physical, digestion, and body image domains in the child version and for eating, weight, and school domains in the parent proxy. Conclusions: The child version and parent proxy of the Persian CFQ-R are valid and reliable measures and can be applied in clinical trials to monitor the quality of life in children with cystic fibrosis. It is recommended to use both versions in conjunction to better interpret the quality of life aspects of children with cystic fibrosis.
