A national registry-based study of ethnic differences in people with multiple sclerosis in Iran.

OBJECTIVE: The relationship between MS and ethnicity has been understudied in the Middle East compared to the United States and Europe. As Iran as the highest prevalence of MS in the Middle East, we decided to investigate the demographic and clinical differences in people with MS (pwMS) from major ethnicities Iran. METHODS: In a cross-sectional study using data from National Multiple Sclerosis Registry in Iran. PwMS from six provinces were chosen and interviewed for determining their ethnicity. Persians (Fars), Kurds, Lurs, Azeris and Arabs with a clear ethnic background were included. Recorded data from the registry was used to compare the demographic and clinical features. RESULTS: A total of 4015 pwMS (74.2% female) were included in the study with an average age of 36.76 ± 9.68 years. Persians and Kurds had the highest percentage of pwMS in youngest and oldest age groups, respectively, with 2.9% and 5.7% (p<0.01). The highest average age of onset was seen in Persians (29.47 ± 8.89) and the lowest observed in Mazandaranis (26.82 ± 7.68, p<0.01). Azeris and Kurds had the highest proportions of pwMS diagnosed <18 and >55, at rates of 12% and 1.6%, respectively (p<0.01). There were statistically significant differences in distribution of phenotypes (p<0.01) and time to progression to secondary progressive MS (p<0.01) such that Persians had the highest rate of clinically isolated syndrome (CIS) at 19.3% and Arabs had highest rates of relapsing-remitting MS (86.2%) and secondary progressive MS (16.4%). Lurs, Azeris and Mazandaranis had significantly more patients progressing to secondary-progressive MS <5 years from diagnosis (p<0.01). There was a significant difference in number of relapses between the ethnicities (p<0.01) with Lurs having the highest proportion of participants reporting >4 relapses with 23.0% and Azeris having the highest percentage of pwMS reporting no relapse (53.0%). Kurds had the highest Expanded Disability Status Scale (EDSS) average at 2.93 ± 1.99 and Lurs had the lowest with 1.28 ± 1.25 (p<0.01). The differences in prevalence of positive family history for the whole cohort between ethnicities were significant (P=0.02), ranging from 12.8% in Kurds to 19.6% in Persians. CONCLUSION: We found Persians to have higher rates of pediatric MS and higher rates of CIS. Kurds and Lurs had higher and lower EDSS scores, respectively. Lurs and Persian had higher annual relapse rates. We also found lower rates of SPMS among Arabs and earlier progression to SPMS in Lurs, Azeris and Mazandaranis. Such differences highlight the importance of the potential role of ethnicities in diagnosis and prognosis of MS, especially considering their observation within the geographical limits of a single country.

The Association Between Physical Function and Hyperkyphosis in Older Females: A Systematic Review and Meta-analysis.

BACKGROUND AND PURPOSE: Thoracic hyperkyphosis may adversely influence physical function in older adults, but the literature is mixed and confounded by possible sex differences. This systematic review and meta-analysis aimed to examine the association between hyperkyphosis and physical function in older females. METHODS: Scopus, ISI Web of Science, Cochrane Library, PubMed, CINAHL, and PEDro databases were searched through 2021 for studies that included measures of thoracic hyperkyphosis and physical function with extractable data for women older than 60 years. Studies were excluded if they were qualitative, case reports, case series, ecological studies, reviews, or were not published in English. The study quality and risk of bias were assessed using checklists from the National Heart, Lung, and Blood Institute. Data were synthesized using Cohen's d effect size and 95% confidence interval (CI), and random-effects models were used for the meta-analyses. RESULTS AND DISCUSSION: Three cohort and 22 cross-sectional studies of fair to good quality met the inclusion criteria. Eight studies reporting single-group data showed a moderate association between greater kyphosis angles and lower physical function ( d = -0.57; 95% CI -0.73, -0.40). Fourteen studies reporting 2-group data showed a large negative effect on physical function for groups with greater kyphosis angles ( d = -1.16; 95% CI -1.53, -0.78). Three studies that reported multivariate data also tended to show negative associations between physical function and hyperkyphosis. Limitations include a relative lack of causal evidence; confirming causation requires additional longitudinal studies. Studies have assessed various physical function categories, including strength, gait, and balance. Future studies could determine the categories of function most affected so that preventive interventions could target hyperkyphosis appropriately. CONCLUSIONS: Hyperkyphosis was associated with lower physical function in older women. Three cohort studies suggest that greater kyphosis angles may predict greater loss of physical function over time. These results imply that therapies that help to minimize hyperkyphosis may help preserve function in older women.

Non-steroidal intravitreal injection for noninfectious uveitic cystoid macular edema: Systematic review and meta-analysis.

PURPOSE: To systematically review the published manuscripts on the non-steroidal intravitreal injection for treatment of noninfectious uveitic cystoid macular edema (CME). METHODS: The PubMed, Scopus, and Web of Science, Science Direct, ProQuest, Cochrane Library, ProQuest, Embase, Clinical Key, and Springer were searched for relevant articles published until May 2022. The random-effects models were used to estimate the mean difference (MD) and 95% confidence interval (CI) for postoperative central macular thickness (CMT) and visual acuity (VA) changes. VA was transformed into the logarithm of the minimum angle of resolution (LogMAR). Meta-regression was conducted for adjusting the effects of potential confounders. RESULTS: A total of 17 relevant studies (258 eyes) were included in this meta-analysis. A significant improvement was observed in CMT in the last follow up (350.89 ± 108.43) compared to the baseline (452.3 ± 112.67) (Log MD = 1.82, 95% CI = 1.62, 2.02; I2 = 57.7%; P = 0.002). Additionally, VA also significantly improved in the last follow up (0.56 ± 0.29) compared to the baseline (0.75 ± 0.3) (Exponential MD = 0.82, 95% CI = 0.69, 0.95; I2 = 0.0%; P = 0.98). The subgroups analyzed included ten studies on anti-vascular endothelial growth factors (VEGF), three studies on infliximab, two studies on methotrexate (MTX), and two studies on diclofenac. All subgroups showed a significant improvement in both CMT and VA at the last follow-up (P < 0.05). CONCLUSION: Non-steroidal intravitreal injection including bevacizumab, ranibizumab, infliximab, MTX and diclofenac appears to be an effective treatment option for noninfectious uveitic CME.

Psychological Experiences in Women with Polycystic Ovary Syndrome: A Qualitative Study.

Background: Polycystic Ovary Syndrome (PCOS) is the most common endocrine disorder among women of reproductive years. In addition to multiple physical problems, this syndrome has many psychological complications. Thus, the present study attempted to explore the psychological experiences of women with PCOS in Iran's sociocultural context. Materials and Methods: The study was carried out in Isfahan, Iran, using a qualitative content analysis method. The participants were selected through purposive sampling from women with PCOS, their spouses, and healthcare providers in hospitals, clinics, workplaces, universities, and physicians' offices between September 2018 and November 2019. Data collection was performed through semi-structured interviews until data saturation. Data analysis was based on conventional content analysis. The interviews were transcribed and coded. Afterward, categories and concepts were extracted by grouping similar codes. Results: A total of 13 women with PCOS, four spouses, and 13 healthcare providers participated in this study. Data analysis yielded five main categories, including the patient's psychological reactions following infertility and its probability, psychological issues following menstrual disorders, patients' fear and concerns about the probability of developing chronic diseases, psychological problems following the disease, and psychological problems resulting from body appearance. Conclusions: The results of this study showed that women with PCOS were exposed to multiple psychological problems. Therefore, preventing and controlling the psychological consequences of PCOS and its complications requires healthcare providers' support and comprehensive and long-term planning to promote the mental health of these women.

Active aging needs from the perspectives of older adults and geriatric experts: a qualitative study.

Introduction: With an increasing rate of population aging and its consequences, preparation for active aging based on older adults' needs is an unavoidable priority. Active aging needs must be identified to help strategic planning for older adults' health and wellbeing. This study aimed to explore the active aging needs from the perspectives of older adults and geriatric experts. Methods: This exploratory-descriptive qualitative study was conducted in four provinces with the oldest populations in Iran. Semi-structured and focus group interviews were conducted with 41 participants (20 older adults and 21 geriatric experts), who were chosen through purposive and snowball sampling. Data were analyzed using the conventional content analysis. Results: This study identified three themes and thirteen categories from the data: (1) basic individual needs with three categories of physiological, psycho-emotional, and spiritual needs; and (2) managerial needs with seven categories of political-legal, socio-economic, and cultural-spiritual infrastructures, academic strategies, an age-friendly environment; technological services, and provision of specialized services and daycare for older adults, and (3) educational needs with three categories of training self-care and self-efficacy, empowering the health care workers; and empowering the family. Conclusion: The results revealed personal, managerial, and educational needs for active aging and could assist policymakers and geriatric experts to promote and meet active aging needs successfully.

The effect of vestibular rehabilitation in Meniere's disease: a systematic review and meta-analysis of clinical trials.

BACKGROUND: Meniere's disease (MD) is a complex disease that can severely affect the quality of life. In this systematic review and meta-analysis, we aimed to investigate the effect of vestibular rehabilitation (VR) versus control/other interventions on the quality of life in patients with MD. METHODS: We searched six electronic databases (PubMed/MEDLINE, Web of Science, EMBASE, Scopus, ProQuest, CENTRAL) from inception to September 30, 2022 with no language restriction for publications comparing the effect of VR with control/ other interventions in patients with MD. The primary outcome was quality of life assessed by dizziness handicap inventory (DHI). RESULTS: Overall, three studies with a total of 465 patients were included in the meta-analysis. All the included studies reported immediate-term DHI scores. A medium effect (standardized mean difference [SMD] = - 0.58, 95% confidence interval [CI] - 1.12; - 0.05) was observed favoring the use of VR to improve DHI scores in patients with MD in the immediate term. Moreover, there was severe heterogeneity in immediate DHI scores among the included studies (χ2 = 22.33, P = 0.00, I2 = 82.1%). CONCLUSIONS: VR rehabilitation can improve the quality of life in patients with MD immediately after treatment. Since all the included studies had a high risk of bias and none had long-term follow-ups, further high-quality research is required to determine the short-, intermediate-, and long-term effects of VR compared to control/other interventions.

Body perception in pregnant women: a qualitative study.

BACKGROUND: Dramatic body changes in pregnancy cause severe concerns among pregnant women about their appearance. Therefore, this study aimed to explore body perception in pregnant women. MATERIALS AND METHODS: The qualitative study, using the conventional content analysis approach, was conducted on Iranian pregnant women who were in their second or third trimester of pregnancy. Participants were selected through purposeful sampling method. In-depth and semi-structured interviews were held with 18 pregnant women aged 22 to 36 years, using open-ended questions. Sampling was performed until data saturation was reached. RESULTS: Three main categories were extracted from 18 interviews: (1) "symbols," with two subcategories, including 'motherhood' and 'vulnerability,' (2) "feelings toward body changes," with five subcategories, including 'negative feelings toward skin changes,' 'feeling unfit,' 'attention-drawing body shape,' 'the ridiculous body shape' and 'obesity,' and (3) "attraction and beauty," with two subcategories, including 'sexual attraction' and 'facial beauty.' CONCLUSION: The results showed that pregnant women's body perception could be described as maternal feelings and feminine attitudes toward changes during pregnancy compared to mental ideals of facial and body beauty. It is recommended that Iranian women's body perception during pregnancy be evaluated using this study results and that counseling interventions be implemented for women with negative body perceptions.

Effectiveness of bosentan in the treatment of systemic sclerosis-related digital ulcers: Systematic review and meta-analysis.

Background: The aim of the present systematic review and meta-analysis was to evaluate the therapeutic efficacy of bosentan, a dual endothelin receptor antagonist, for systemic sclerosis (SSc) patients with digital ulcers (DUs). Materials and Methods: A systematic search of MEDLINE, Embase, Web of Science, and Scopus was done using appropriate keywords till September 2021. Weighted mean difference (WMD) as the effect of therapeutic efficacy of bosentan on continuous outcomes was an estimate. Furthermore, the pooled prevalence of diffuse SSc and limited SSc was computed. Fixed or random effects models when appropriate were used for data synthesis. Results: Totally, 469 patients, with a mean age ranging from 48.1 to 63.7 years, from 8 studies were included in the systematic review and meta-analysis. The pooled frequency of diffuse SSc and limited SSc was 56% (95% confidence interval [CI]: 39%, 73%) and 44% (95% CI: 27%, 61%). The pooled prevalence of new DUs following bosentan treatment was 21% (95% CI: 10%, 33%). The results of the meta-analysis showed a pooled mean decrease of WMD: -0.09 (95% CI: -0.020, 0.02, P = 0.10), WMD: -2.82 (95% CI: -5.91, 0.27, P = 0.07), and WMD: -6.65 (95% CI: -9.49, -3.82, P < 0.001) in mean SSc-Health Assessment Questionnaire, pain, and Rodnan score, respectively. Our meta-analysis also indicated a significant pooled decrease in the number of new DUs in SSc patients compared to placebo subjects (WMD: -0.89 [95% CI: -1.40, -0.37; P = 0.001]) and baseline values (WMD: -1.34 (95% CI: -1.95, -0.73; P < 0.001). Conclusion: Bosentan possibly is an efficacious treatment option for SSc-related DUs. Although further large-scale randomized clinical trials are required to confirm the preliminary finding and underlying mechanisms of action.

A systematic review evaluating the efficacy of autologous hematopoietic transplantation for diffuse large B cell lymphoma-type Richter syndrome.

Background: Chronic lymphocytic leukemia (CLL) can transform into fast growing lymphoma for diffuse large B-cell lymphoma (DLBCL) called Richter's syndrome (RS), which is commonly related to an existence of large B-cells with equal or larger size than macrophage nuclei or more than twice those of normal lymphocyte. We conducted a systematic review of the existing literature to assess the clinical efficacy of auto-HCT for patients with RS. Methods: We searched 4 main databases; EMBASE, Google Scholar, Scopus, PubMed and Web of Science and was done on December 26, 2021. All analyses in this study were performed by Stata software and this review was reported in accordance with PRISMA 2020. Results: Data was extracted from 4 articles; the total number of patients was reported to be 110. Based on the meta-analysis findings, pooled overall survival rate was 56.36% (95%CI= (46.98-65.31). In figure 2, the forest plot of combined results is shown. Conclusion: Despite the use of common treatment regimens such as chemo immunotherapy and the availability of novel therapies including B-cell receptor inhibitors and rituximab-cyclophosphamide-hydroxydaunorubicin-Oncovin-prednisone (CHOP-R) regimen, the status of disease progression and recovery in RS cases is still not strong enough.

Is CKD Screening Program Necessary in Developing Countries?

INTRODUCTION: The prevalence of congenital anomaly of kidney and urinary tract (CAKUT) and related chronic kidney disease (CKD) may be increased in countries with higher rate of consanguineous marriage. Therefore, we evaluated the prevalence of CKD by biochemical and kidney ultrasound measurements in the firstgrade pupils. METHODS: This cross -sectional study was carried on children aged 6 to 7 years. Urine analysis, serum creatinine, urine microalbumin to creatinine ratio and kidney ultrasound have been evaluated for participants. RESULTS: 653 children were recruited to the study. Stage 1 and stage 2 systolic hypertension have been found in 6.5 and 1%, respectively. The percentage of stage 1 and stage 2 diastolic hypertension were 1.3 and 0.3%, respectively. Both weight Z-score and waist Z-score had positive correlation with systolic and diastolic blood pressure. Microalbuminuria (in 2.5%) did not have any correlation with the following factors: hypertension, body mass index, microscopic hematuria, glomerular filtration rate, kidney sonographic abnormalities or kidney parenchymal thickness and family history of kidney transplantation. GFR less than 90 mL/ min /1.73 m2 has been detected in 1.8% of the students. Only 1.7% had urine RBC more than 5 in each high-power field (hpf). Approximately 1.5% had anatomical abnormality of kidney and urinary tract (hydronephrosis or hydroureter). CONCLUSION: Considering the higher prevalence of elevated blood pressure and microalbuminuria in Iranian children, a CKD screening program based on evaluating microalbuminuria and blood pressure measurement is needed. However, irrespective of high prevalence of consanguineous marriage in Iran, using kidney ultrasound as a screening tool has not been recommended.  DOI: 10.52547/ijkd.7306.

Effect of Oat (Avena sativa L.) Consumption on Lipid Profile With Focus on Triglycerides and High-density Lipoprotein Cholesterol (HDL-C): An Updated Systematic Review.

Hypercholesterolemia is a significant risk factor for heart disease. The soluble fiber in oat (Avena sativa L.), beta-glucan has been shown to significantly lower serum total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels but not triglycerides (TG) and high-density lipoprotein cholesterol (HDL-C) according to previous studies, reviews, and meta-analyses. However, the effect of oat consumption on the TG and HDL-C is controversial and has not been expanded enough. We did this review study to find out about the effect of oat on lipid profile especially TG and HDL-C more specifically and meticulously with their details. After searching PubMed, Web of Science, and Google scholar we included 17 studies in our review. Our results similar to other reviews showed that oat reduced the TC, VLDL, and LDL-C more significantly than TG. Of 17 included studies 6 studies reported reduction of TG level, and only 1 study reported HDL-C improvement followed by oat consumption. A more detailed review of studies that reported positive effects of oat/ beta-glucan consumption on TG showed that in healthy people with normal lipid profile oat intake might reduce TG effectively and also in overweight people/those with diabetes or metabolic syndrome if a higher amount of oat or/and longer duration applied. Consuming oat in conjunction with calorie-reducing diets or using it with DHA can cause a significant TG reduction. It may be concluded that, in addition to lowering TC and LDL-C, a considerable improvement in TG or HDL-C can be accomplished by adjusting factors such as oat consumption dose or consumption duration or utilizing oat in conjunction with a proper diet program. To conclude, more research on this topic is required.

Prevalence and Antibiotic Resistance of Clostridioides (Clostridium difficile) In Meat and Meat Products: A Systematic Review and Meta-Analysis.

Background: Meat and meat products are introduced as one of the frequent sources of Clostridioides difficile. We aimed to determine the prevalence and antibiotic resistance of C. difficile isolates in meat and meat products using a systematic review and meta-analysis. Methods: A literature search was performed in the primary international and bibliographic databases such as MEDLINE (PubMed), Cochrane Library, Embase, Scopus, and Web of Science to achieve all articles related to the prevalence and antibiotic resistance rates from 2007 to 2022. Results: The 278 retrieved articles were reduced to 54 worldwide eligible studies after screening and matching inclusion/exclusion criteria. C. difficile was examined in different types of samples and its resistance to 10 antibiotics. The pooled prevalence of C. difficile was 3.4% in all samples. C. difficile pooled prevalence was detected in fish, poultry, and red meat groups with 6.9%, 5.2%, and 3.2%, respectively. Regarding antibiotic resistance, the highest pooled prevalence was for ciprofloxacin (86.6%), followed by clindamycin (42.6%) and erythromycin (34%). The lowest pooled prevalence was observed in metronidazole (7.6%), vancomycin (6.6%), and chloramphenicol (6%). Conclusion: Low resistance was found to commonly used drugs for C. difficile infection (CDI) treatment. Since each antibiotic can be predisposing cause for CDI development, this finding possibly will be warning from a One Health viewpoint about the misuse of antibiotics in the chain of farm to fork including agriculture, animal husbandry and the food industry and also their injudicious use in medicine.

Effect of using 5A's model for lifestyle counseling on psychological symptoms in women with polycystic ovary syndrome: a randomized field trial.

Lifestyle modification in women with polycystic ovary syndrome (PCOS) could be associated with increased psychological symptoms. This study aimed to evaluate the effect of lifestyle modification counseling using 5A's model on the psychological symptoms of women with PCOS. This double-blind, randomized field trial was performed on 70 women with PCOS in two groups of lifestyle modification counseling based on 5A's model and counseling without using the model. The intervention was performed based on five stages of the 5A's model (Assess, Advise, Agree, Assist, Arrange) during a week, and psychological symptoms were assessed using Symptom Checklist-90-R before the intervention and one and three months after the intervention. The results showed that one and three months after the intervention, the level of psychological symptoms, except obsessive-compulsive level, were significantly lower in the intervention group than in the control group (p < 0.05). Moreover, the level of these symptoms decreased over time in the intervention group (p < 0.0001). Using the 5A's model in lifestyle modification counseling is associated with the promotion of psychological health in women with PCOS, and this model is recommended for lifestyle counseling in women with polycystic ovary syndrome.

A reproductive health-care program for surrogate mothers: A mixed methods study.

BACKGROUND: Surrogacy has become an alternative family formation option for women who are unable to carry a pregnancy. There is no comprehensive care program despite the different nature of this pregnancy. The present study aimed to develop a reproductive health-care program for surrogate mothers within the cultural and social context of Iran. MATERIALS AND METHODS: In the present sequential exploratory mixed methods study, first through a qualitative approach surrogate mothers, care providers, and policy makers of reproductive health services were selected purposefully. Data were collected by using the in-depth semi-structured interviews and analyzed. A care program draft was designed by integrating results of the qualitative study and reviewing the literature and guidelines, then appropriateness of each proposed care was assessed by a two-Rounds Delphi technique (RAM), and the final reproductive health-care program for surrogate mothers was developed. RESULTS: The surrogate mothers' reproductive health needs were summarized in four main categories: surrogate mothers' extra care, educational training, psychological support, and protecting against surrogacy's social and familial consequences. The reproductive health-care program for surrogate mothers were developed in four sections: prepregnancy health screenings and legal counseling; special care during embryo transfer until pregnancy confirmation; psychological support and prenatal care of surrogacy until delivery and follow-up postpartum care. CONCLUSION: Women face many challenges in surrogacy and need special care such as legal counseling, reproductive health care, and psychological support. Implementation of this care program seems to help improve the reproductive health of these mothers.

Effect and Safety of Castor Oil on Labor Induction and Prevalence of Vaginal Delivery: A Systematic Review and Meta-Analysis.

Background: Castor oil is used in some countries to induce labor, but results on its effectiveness and safety is controversial. This systematic review and meta-analysis aimed to evaluate the effect of castor oil on labor induction and prevalence of vaginal delivery along with investigating its safety. Materials and Methods: PubMed, Scopus, Web of Science, and Google Scholar were searched systematically up to September 2020. Observational studies and Randomized Clinical Trials (RCTs), which assessed the effect of castor oil on labor induction in English and Persian languages using different combinations of the related key terms and Medical Subject Headings (MeSH) terms were collected and analyzed independently by two authors. Random effect model was used for meta-analysis. The studies were included in which the Relative Risk (RR) had been reported with 95% Confidence Intervals (CIs). Results: A total of 12 studies consisting 1653 pregnant women were included. The mean age of women who used castor oil was 24.72 years and in control group was 24.67 years. Results showed that labor induction was significantly higher in castor oil group than control group (RR: 3.27; 95% CI (1.96, 5.46)). Prevalence of vaginal delivery was 81% in the castor oil group and 69% in the control group. Conclusions: It can be concluded that use of castor oil has positive effect on labor induction and increases the prevalence of vaginal delivery. None of the studies considered in this meta-analysis reported any serious harmful effects for the use of castor oil.

Length of stay in patients undergoing total knee arthroplasty.

Background: Minimizing costs associated with the care of patients undergoing total knee arthroplasty (TKA) can reduce the burden on health systems that regularly struggle with limited resources. Predicting and reducing TKA associated length of stay (LoS) can therefore be invaluable. This study aimed to determine the factors that impact LoS in patients undergoing TKA and propose a model design to predict LoS. Methods: A retrospective study was performed on patients undergoing TKA in a tertiary teaching hospital. Patients who underwent TKA from March 2007 to March 2021 were included in the study. Data were extracted from available electronic and paper records. Variables evaluated included: patients' demographic data, general admission data, laboratory data, transfusion, operation data, and preoperative comorbidities and medical history. Independent T-test, one-way ANOVA, and Pearson correlation were used for univariate data analysis. For multivariate analysis and model designing, multiple regression stepwise methods were used. Results: 878 patients were included in this study. Mean LoS was 6.09 (SD = 1.83) with a median of 6 days. Factors found to have a significant effect on length of stay were age, revision surgery, Anesthesia type, intensive care unit admission, insurance, transfusion, preoperative hemoglobin level, and pre-operative platelet (Plt) count. Applying a multiple regression stepwise model to these variables showed that the following pre-operative factors can be predictive for LoS: revision surgery, sex, medical insurance, hemoglobin level, and Plt count. Conclusions: It was deduced that sex, revision, pre-operative hemoglobin and Plt level and health insurance were the best predictors for LoS in patients undergoing TKA.

The Prevalence of Metabolic Syndrome in First Degree Relatives of Patients with Obstructive Sleep Apnea Syndrome: A Case-Control Study.

Background: There was the association between the metabolic syndrome (MS) and obstructive sleep apnea (OSA). Also, the genetic factors have been implicated in the OSA. Our aim was to compare the frequency of MS in first-degree relatives (FDRs) of OSA patients with healthy controls. Methods: 39 FDR (parents, siblings, and children) of patients diagnosed with OSA at Bamdad Respiratory and Research Center as cases and age- and sex-matched healthy controls were included in the current case-control pilot study. The sampling method was convenience sampling based on having inclusion criteria and consent to participate in the study. Demographic characteristics and essential criteria for diagnosing MS included blood pressure, anthropometric [weight (kg), height (cm), waist circumference (cm) and body mass index (BMI) (kg/m2)], and biochemical indices (lipid profile and blood glucose) were assessed based on standard protocols. Results: In the comparison of the demographic and clinical characteristics of two39 cases and control groups, weight and diastolic blood pressure were significantly higher in case group than controls (P < 0.05). Case and control groups were not significantly different in the frequency of MS (P > 0.05). Although, the frequency of hypertension as an important cardiovascular risk factor was higher in cases than controls (P < 0.05). Conclusions: The present study demonstrates that the frequency of MS is not significantly different between FDRs of OSA patients and controls. However, further large-scale studies are warranted to detect the frequency of MS in people with hereditary background for OSA compared to general population.

A comparison of rituximab with cyclophosphamide in terms of efficacy and complications as induction therapy for treating granulomatosis with polyangiitis: A three-center study.

OBJECTIVE: Granulomatosis with polyangiitis (GPA), formerly known as Wegner's granulomatosis, is a rare vasculitic syndrome classified under Anti-Neutrophilic Cytoplasmic Autoantibody (ANCA)-associ- ated vasculitides, which is fatal if untreated. The mainstay of treatment consists of immunosuppression using a combination of corticosteroids with either rituximab (RTX) or cyclophosphamide (CYC). We aimed to compare the 4-year clinical outcomes between patients with GPA receiving CYC and RTX as remission induction. METHODS: In this retrospective cohort, we used patient data from 92 patients with GPA at two large teaching hospitals and a private clinic in Isfahan, Iran. The patients were classified based on the medi- cation they received for remission induction into RTX and CYC groups. The main outcomes were rate of death and relapse, disease activity assessed based on the Birmingham Vasculitis Activity Score (BVAS), disease-related complications, laboratory markers, and adverse-drug-reactions. RESULTS: Fifty-three (57.6%) patients received CYC, whereas 39 (42.4%) received RTX. The mean duration of follow-up was 3.6 (62) years. Most of patients (70%) had a successful remission, while 20.7% experi- enced a relapse and 8.7% of patients died. The rate of death and relapse did not differ between the RTX and CYC groups. Disease-related complications involved an insignificantly higher proportion of patients in the CYC (12/53) group than the RTX (4/39) group. Patients in both groups showed a signifi- cant decrease in BVAS during follow-ups irrespective of the medication exposure. The rate of adverse events was similarly low (n 1/4 1) in both groups. CONCLUSION: RTX and CYC were similar in inducing remission and reducing adverse clinical outcomes among patients with GPA with acceptable side effect profiles.

Diagnostic Value of Nonacid Nucleic Blood Tumor Marker Panels in Early Diagnosing Breast Cancer: A Systematic Review and Network Meta-Analysis.

This study is aimed at determining the best nonacid nucleic blood tumor marker panels in terms of sensitivity, specificity, and accuracy in order to detect breast cancer in early stages (I, II, and III) among eligible women for breast cancer screening. PubMed, Web of Science, Embase, Scopus, and Cochrane were systematically reviewed to assess nonacid nucleic blood tumor marker panels' diagnostic value in women, both healthy and patient (before any anticancer treatment), for detecting breast cancer. A network meta-analysis was carried out using a Bayesian network meta-analysis to estimate combined odd ratio (OR) and 95% CI credible interval for presenting the results. Rankograms plot was drawn to rank the diagnostic value of different panels. Of the 2358 titles initially identified, 9 studies and 8 panels were included in the network meta-analysis. Panels A (MMP-9/TIMP-1) and K (TF1+TF2+TF3) had the highest sensitivity in early stages, as panel A with OR = 11.61 and 95% CI (1.49-102.5) demonstrated a better function than mammography. Panels H (CA 15.3 + IL-18) and A (MMP-9/TIMP-1) had the highest specificity in early stages, but no significant difference with mammography. Panels A (MMP-9/TIMP-1) and H (CA 15.3 + IL-18) had the highest accuracy in early stages, as they significantly exhibited a higher function than mammography with OR = 6.87 and 95% CI (2.07-31.35) as well as OR = 3.44 and 95% CI (1.15-11.07), respectively. Panel A including MMP-9/TIMP-1 in early stages demonstrated a higher diagnostic value for breast cancer than the rest of the panels.
