The visceral adiposity index and lipid accumulation product as predictors of cardiovascular events in normal weight subjects.

INTRODUCTION: Visceral adipose tissue (VAT) has an important role in the incidence of cardiovascular disease (CVD) than obesity by itself. The visceral adiposity index (VAI) and lipid accumulation product (LAP) are surrogate indices for measuring VAT. The aimed of this study was to investigate the association of these markers with cardiovascular events among populations with different BMI category in Mashhad, northeast of Iran. METHOD: The present study comprised a prospective cohort of 9685 men and women (35-65 years) who were recruited from MASHAD study. BMI category was defined as normal weight (BMI <25), over weight (25 ≤ BMI<30) and obese (BMI≥30). Demographic, laboratory evaluations, anthropometric and metabolic parameters were performed. Logistic and Cox regression analyses were used to determine the association and risk of cardiovascular events with VAT and LAP. RESULTS: The mean VAI and LAP in CVD patients were significantly higher than in healthy ones in all 3 groups. In terms of CVD event prediction, VAI and LAP had significant association with the incidence of CVD in the second (RR (95% CI): 2.132 (1.047-4.342) and 2.701 (1.397-5.222), respectively) and third tertiles (RR (95% CI): 2.541 (1.163-5.556) and 2.720 (1.159-6.386), respectively) in the normal group, but this association was only found in the third tertiles (RR (95% CI): 2.448 (1.205-4.971) and 2.376 (1.086-5.199), respectively) in the overweight group. The result couldn't find this association for the obese group. CONCLUSION: In this study, we found that there was a significant association between LAP and VAI and cardiovascular events in normal weight and over-weight groups; however, no significant relationship was found in the obese group.

ABO and Rh blood groups in patients with lupus and rheumatoid arthritis.

BACKGROUND: Systemic lupus erythematous (SLE) and rheumatoid arthritis (RA) are autoimmune diseases in which the antigen-antibody system plays an important role. As blood group and Rh are determined by the presence or absence of antigens on the surface of red blood cells (RBCs), we aimed to determine the distribution of ABO and Rh blood groups in SLE and RA patients and its association with disease manifestations. METHODS: This short communication is based on a study that was conducted on 434 SLE and 828 RA patients. We evaluated the distribution of ABO and Rh blood groups in RA and SLE patients. RESULTS: This study projected that in lupus patients, Coombs-positive autoimmune hemolytic anemia and arthritis were more common among the B blood type and Rh-positive group, respectively. Furthermore, there was no relation between ABO and Rh blood group and rheumatoid factor (RF) and anti-Cyclic Citrullinated Peptide (anti-CCP) seropositivity. Moreover, there was no difference in distribution of blood groups in RA and SLE patients. CONCLUSION: The higher frequency of blood group B in hemolytic anemia, and positive Rh in arthritis in lupus patients, develop the hypothesis of probable role of ABO blood group antigen in some manifestations of lupus.

Self-assembly of ionic and non-ionic surfactants in type IV cerium nitrate and urea based deep eutectic solvent.

Understanding and manipulating micelle morphology are key to exploiting surfactants in various applications. Recent studies have shown surfactant self-assembly in a variety of Deep Eutectic Solvents (DESs) where both the nature of surfactants and the interaction of the surfactant molecule with the solvent components influence the size, shape, and morphology of the micelles formed. So far, micelle formation has only been reported in type III DESs, consisting solely of organic species. In this work, we have explored the self-assembly of cationic surfactant dodecyl trimethylammonium nitrate/bromide (C12TANO3/C12TAB), anionic surfactant sodium dodecyl sulfate (SDS), and non-ionic surfactants hexaethylene glycol monododecyl ether (C12EO6) and octaethylene glycol monohexadecyl ether (C16EO8) in a type IV DES comprising metal salt, cerium (III) nitrate hexahydrate, and a hydrogen bond donor, urea, in the molar ratio 1:3.5. C12TANO3, C12TAB, C12EO6, and C16EO8 form spherical micelles in the DES with the micelle size dependent on both the surfactant alkyl chain length and the head group, whereas SDS forms cylindrical micelles. We hypothesize that the difference in the micelle shape can be explained by counterion stabilization of the SDS headgroup by polycations in the DES compared to the nitrate/bromide anion interaction in the case of cationic surfactants or molecular interaction of the urea and the salting out effect of (CeNO3)3 in the DES on the alkyl chains/polyethoxy headgroup for non-ionic surfactants. These studies deepen our understanding of amphiphile self-assembly in this novel, ionic, and hydrogen-bonding solvent, raising the opportunity to use these structures as liquid crystalline templates to generate porosity in metal oxides (ceria) that can be synthesized using these DESs.

The Association between Substance Use Disorders and Long-Term Outcome of Stroke: Results from a Population-Based Study of Stroke among 450,229 Urban Citizens.

INTRODUCTION: Little is known regarding long-term stroke outcomes in patients with substance use disorder (SUD). Based on anecdotal data, some individuals use illicit drugs, particularly opioids, in an attempt to reduce stroke mortality, disability, or recurrence. This study is aimed to assess the effect of SUD on stroke outcomes. METHODS: Patients were recruited from the Mashhad Stroke Incidence Study, a population-based study of stroke in Iran. For a period of 1 year, all patients with first-ever stroke (FES) were recruited and then followed up for the next 5 years. Disability and functional dependency were defined using modified Rankin Scale (>2) and Barthel Index (<60), respectively. We compared the cumulative rates of mortality in follow-up points using the log-rank test. We used multivariable logistic, Cox regression and competing risk models to assess adjusted hazard ratio (aHR) with 95% confidence interval (CI) of stroke disability, functional dependency, mortality, and recurrence among those with a history of SUD. RESULTS: 595 FES patients (mean age of 64.6 ± 14.8 years) were recruited in this study. Eighty-one (13.6%) were current substance users, including opium (n = 68), naswar (n = 5, 6.1%), hashish (n = 1), heroin (n = 1), and (n = 7) others. The frequency of vascular risk factors was similar between the SUD and non-SUD groups, except for a higher rate of cigarette smoking in the SUD group (p < 0.001). After adjusting for various sociodemographic variables, vascular risk factors, and the severity of stroke at admission, SUD increased the 3-month (aHR: 1.60, CI: 1.01-2.49), 1-year (aHR: 1.73, CI: 1.20-2.65), and 5-year (aHR: 1.72, CI: 1.23-2.35) poststroke mortality risk. We did not observe a significant change in the risk of stroke recurrence, disability, and functional dependency in those with a history of SUD. CONCLUSION: SUD increased the hazard ratio of stroke mortality with no effect on the disability rate. The public should be advised about the potential harm of substance abuse.

Association of Healthy Eating Index and the Alternative Healthy Eating Index with the cell blood count indices.

OBJECTIVES: There is an association between diet quality and markers of inflammation. We aimed to investigate the relationship between diet quality with cell blood count (CBC) and inflammatory indices such as red cell distribution width (RDW) and white blood cell count (WBC). STUDY DESIGN: A total of 367 male subjects aged 20-69 yrs, who were employees of Shahid Hasheminejad Gas Processing Company (SGPC) completed the study. METHODS: All participants completed a questionnaire that contained questions about demography. Standard protocols were used for measuring anthropometric indices in all subjects. Blood samples were collected after a 12 hrs fast from all participants. Biochemical parameters were determined in all participants using an auto-analyzer (Eppendorf, Germany). Systolic and diastolic blood pressure were measured using a standard mercury sphygmomanometer. CBC was measured using the Sysmex auto analyser system (KX-21 N). The HEI/AHEI scores extracted from a validated food frequency questionnaire (FFQ) to evaluate the diet quality. Data analyses were performed using SPSS 16 (SPSS Inc., IL, and USA). RESULTS: A total of 674 men (aged 43.68±9.09 yrs) completed the study. The CBC indices were not significantly different between the HEI/AHEI classifications among the Iranian men (p-value >0.05 for all variables). Moreover, there was no association between HEI/ AHEI with the CBC indices in our population (p-value >0.05 for all variables). CONCLUSIONS: In summary, there was no association between the diet quality with the cell blood count parameters among Iranian men.

Self-perceived acute psychological stress and risk of mortality, recurrence and disability after stroke: Mashhad Stroke Incidence Study.

This longitudinal study was designed to evaluate the association between acute pre-stroke stress and the severity stroke and its outcomes including mortality, recurrence, disability and functional dependency. Patients with first-ever stroke (FES) were recruited from the Mashhad Stroke Incidence Study. Patients were asked about any acute severe pre-stroke stress in the 2 weeks prior to index stroke. Disability and functional disability were defined using modified the Rankin Scale and Barthel Index, respectively. We used logistic and ordinal regression tests to assess the association between acute pre-stroke stress and study outcomes. Among 624 patients with FES, 169 reported acute pre-stroke stress. Patients with acute pre-stroke stress were younger than those without stress (60.7 ± 14.4 vs. 66.2 ± 14.7; p < 0.001). The frequency of traditional vascular risk factors was not different in patients with and without acute pre-stroke stress. We did not find any association between acute pre-stroke stress and stroke outcomes. Although acute stress was common in our cohort, our results did not support an association between acute pre-stroke stress and the severity of stroke at admission and long-term stroke outcomes.

Regular physical activity postpones age of occurrence of first-ever stroke and improves long-term outcomes.

OBJECTIVE: Few data are available on the associations between the level of pre-stroke physical activity and long-term outcomes in patients with stroke. This study is designed to assess the associations between pre-stroke physical activity and age of first-ever stroke occurrence and long-term outcomes. METHODS: Six hundred twenty-four cases with first-ever stroke were recruited from the Mashhad Stroke Incidence Study a prospective population-based cohort in Iran. Data on Physical Activity Level (PAL) were collected retrospectively and were available in 395 cases. According to the PAL values, subjects were classified as inactive (PAL < 1.70) and active (PAL ≥ 1.70). Age at onset of stroke was compared between active and inactive groups. Using logistic model, we assessed association between pre-stroke physical activity and long-term (5-year) mortality, recurrence, disability, and functional dependency rates. We used multiple imputation to analyze missing data. RESULTS: Inactive patients (PAL < 1.70) were more than 6 years younger at their age of first-ever-stroke occurrence (60.7 ± 15.5) than active patients (67.0 ± 13.2; p < 0.001). Patients with PAL< 1.7 also had a greater risk of mortality at 1 year [adjusted odds ratio (aOR) = 2.31; 95%CI: 1.14-4.67, p = 0.02] and 5 years after stroke (aOR = 1.81; 95%CI: 1.05-3.14, p = 0.03) than patients who were more physically active. Recurrence rate, disability, and functional dependency were not statistically different between two groups. Missing data analysis also showed a higher odds of death at one and 5 years for inactive patients. CONCLUSIONS: In our cohort, we observed a younger age of stroke and a higher odds of 1- and 5-year mortality among those with less physical activity. This is an important health promotion strategy to encourage people to remain physically active.

Prevalence of ABO and Rh blood groups and their association with demographic and anthropometric factors in an Iranian population: Mashad study.

BACKGROUND: Blood groups appear to be markers for various human diseases and their distribution among different communities, ethnic groups and geographical boundaries varies over time. AIMS: We aimed to investigate the frequency of ABO and Rh blood groups and their relationship with demographic and anthropometric characteristics among Iranian residents in Mashad. METHODS: ABO and Rh blood groups were determined among 7268 participants from the MASHAD cohort study and their relationships with demographic and anthropometric parameters were evaluated. This part of the study was done in January 2017. Student t-test, ANOVA, Bonferroni' and Chi-squared were used for comparison of quantitative and qualitative variables. RESULTS: The most common blood group was O (33.8%); AB was the least common (8.3%). The prevalence of Rh-positive and Rh-negative was 88.2% and 11.8% respectively. There were statistically significant associations between ABO blood groups and demi-span (P = 0.03), even after correction for multiple comparisons. CONCLUSION: Our findings showed there was no relationship between ABO blood groups and demographic characteristics although there was an association with anthropometric measurements such as demi-span.

Evaluation of ABO blood group in subjects with CVD risk factors in a population sample from northeastern Iran.

BACKGROUND AND AIMS: The ABO blood group system is a genetic polymorphism which can affect the clearance of von Willebrand factor. We aimed to assess the levels of newer biomarkers of cardiovascular disease (CVD) risk; pro-oxidant-antioxidant balance (PAB), high sensitivity C-reactive protein (hs-CRP) and anti-heat-shock protein27 (anti-Hsp27) antibody titers in subjects with various blood groups (A, B, AB and O) and with or without traditional CVD risk factors. METHODS: The cross-sectional study comprised 6910 subjects. Antigen-antibody agglutination was evaluated by the slide test method for identification of ABO blood groups. RESULTS: Among three markers, only Serum anti-Hsp27 titers significantly differed between the four blood groups and showed the highest and lowest values in AB and O blood groups (0.26 ± 0.22 and 0.23 ± 0.18 OD, respectively; P < 0.05). Serum anti-Hsp27 was higher in individuals with an AB blood group with metabolic syndrome (MetS), dyslipidemia, hypertension (HTN) and obesity and it was lower in subjects with O blood group; though, two other biomarkers, serum PAB and hs-CRP, were not significantly different between the ABO blood groups. However, they were not different among blood groups in participants with or without diabetes mellitus (DM) (P > 0.05). CONCLUSION: Individuals with an AB blood group and high levels of anti-Hsp27 antibody titers may be predisposed to CVDs that can be mediated through the traditional CVD risk factors among middle-aged subjects from northeastern Iran. The fact that differences in anti Hsp27 are only found in the subgroup with other risk factors suggest that the difference between ABO blood groups is a consequence rather than a cause.

Call to Action: SARS-CoV-2 and CerebrovAscular DisordErs (CASCADE).

BACKGROUND AND PURPOSE: The novel severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2), now named coronavirus disease 2019 (COVID-19), may change the risk of stroke through an enhanced systemic inflammatory response, hypercoagulable state, and endothelial damage in the cerebrovascular system. Moreover, due to the current pandemic, some countries have prioritized health resources towards COVID-19 management, making it more challenging to appropriately care for other potentially disabling and fatal diseases such as stroke. The aim of this study is to identify and describe changes in stroke epidemiological trends before, during, and after the COVID-19 pandemic. METHODS: This is an international, multicenter, hospital-based study on stroke incidence and outcomes during the COVID-19 pandemic. We will describe patterns in stroke management, stroke hospitalization rate, and stroke severity, subtype (ischemic/hemorrhagic), and outcomes (including in-hospital mortality) in 2020 during COVID-19 pandemic, comparing them with the corresponding data from 2018 and 2019, and subsequently 2021. We will also use an interrupted time series (ITS) analysis to assess the change in stroke hospitalization rates before, during, and after COVID-19, in each participating center. CONCLUSION: The proposed study will potentially enable us to better understand the changes in stroke care protocols, differential hospitalization rate, and severity of stroke, as it pertains to the COVID-19 pandemic. Ultimately, this will help guide clinical-based policies surrounding COVID-19 and other similar global pandemics to ensure that management of cerebrovascular comorbidity is appropriately prioritized during the global crisis. It will also guide public health guidelines for at-risk populations to reduce risks of complications from such comorbidities.

Correlations between COVID-19 and burden of dementia: An ecological study and review of literature.

INTRODUCTION: Current evidence on the association between COVID-19 and dementia is sparse. This study aims to investigate the associations between COVID-19 caseload and the burden of dementia. METHODS: We gathered data regarding burden of dementia (disability-adjusted life years [DALYs] per 100,000), life expectancy, and healthy life expectancy (HALE) from the Global Burden of Disease (GBD) 2017 study. We obtained COVID-19 data from Our World in Data database. We analyzed the association of COVID-19 cases and deaths with the burden of dementia using Spearman's rank correlation coefficient. RESULTS: Globally, we found significant positive (p < .001) correlations between life expectancy (r = 0.60), HALE (r = 0.58), and dementia DALYs (r = 0.46) with COVID-19 caseloads. Likewise, we found similar correlations between life expectancy (r = 0.60), HALE (r = 0.58) and dementia DALYs (r = 0.54) with COVID-19 mortality. CONCLUSION: Health policymakers should clarify a targeted model of disease surveillance in order to reduce the dual burden of dementia and COVID-19.

Interaction of smoking, hyperhomocysteinemia, and metabolic syndrome with carotid atherosclerosis: A cross-sectional study in 972 non-diabetic patients.

OBJECTIVES: Little is known about the interactions between hyperhomocysteinemia and metabolic syndrome (MetS) in individuals at risk for atherosclerosis. The aim of this study was to assess the burden of atherosclerosis in patients with MetS and hyperhomocysteinemia. METHODS: We assessed the interaction of MetS with other risk factors including hyperhomocysteinemia in 972 patients with a history of stroke, transient ischemic attack, or carotid stenosis. MetS was defined as by the International Diabetes Federation as body mass index ≥30 kg/m² and two or more of the following: hypertension, high triacylglycerides, and low high-density lipoprotein. We defined hyperhomocysteinemia as plasma total homocysteine ≥14 µmol/L. Patients with diabetes were excluded. Carotid total plaque area (TPA), a strong predictor of cardiovascular risk, was measured by carotid ultrasound. The association of TPA with MetS, and interaction with related risk factors, was assessed by multiple linear regression. RESULTS: Complete data were available on 972 non-diabetic patients. Of these, 179 (18.4%) had MetS. Patients with MetS and hyperhomocysteinemia (P < 0.001) or smoking (P = 0.02) had a higher TPA compared with those with MetS and normal plasma total homocysteine levels. In linear regression, there was a significant association of MetS (P = 0.004), hyperhomocysteinemia (P = 0.01), and smoking (P = 0.004) with increased TPA. CONCLUSIONS: Patients with MetS and smoking or hyperhomocysteinemia are at particularly high cardiovascular risk. Targeted atherosclerosis prevention should include identification and treatment of MetS, smoking, and hyperhomocysteinemia (including that due to unrecognized metabolic vitamin B12 deficiency).

A comparison of dietary intake between personnel of a gas processing company and a sample population of public employees from Mashhad.

INTRODUCTION: An imbalanced dietary pattern may result in a number of non-communicable disorders that include: obesity, diabetes, metabolic syndrome, cardiovascular diseases, and subsequently impaired quality of life (QOL). Micro- and macro-nutrients play some important roles in maintaining human health. The objective of this study was to compare dietary intake of employees of a gas processing company, who were provided with meals by their employee, with staff from other public employers from Mashhad, in northeastern Iran. METHODS: Twenty-four-hour food recall and a food frequency questionnaire (FFQ) were used to evaluate dietary intakes of 654 male employees of Shahid Hasheminejad Gas Processing (SHGP) Company (case group), and 681 randomly selected male public employees from Mashhad as control subjects in this observational, analytic, longitudinal, prospective cohort study. The analysis of the dietary intakes was performed using Dietplan6 software. RESULTS: Dietary macro and micro-nutrients were evaluated: including total energy, fat, MUFA, PUFA, trans fatty acids, cholesterol, starch, fiber, protein, total nitrogen, zinc, phosphor, potassium, calcium, manganese, selenium, iodine, sodium, copper, retinol, carotene, thiamin, riboflavin, niacin, pantothen, vitamin B6, biotin, folate, vitamin B12, vitamin C and vitamin D. The intake of macro-nutrients, including: energy, fat, monounsaturated fatty acids, polyunsaturated fatty acids, carbohydrates, starch, and protein; minerals including zinc, iron, selenium; and vitamins including niacin and vitamin D were higher in the SHGP group, compared to the control group (P < 0.05). The dietary intake of the SHGP group contained lower amounts of several mineral and vitamins, which included: iodine, sodium, carotene, thiamin, pantothenic acid, vitamin B6, biotin, folic acid, and vitamin C, in comparison with the control group (P < 0.05). CONCLUSION: In conclusion, we suggest it will be important to evaluate the composition of meals provided by companies and organizations, especially those that provide their employees with the majority of their food intake.

Acupuncture in the treatment of HTLV-I-associated myelopathy / tropical spastic Paraparesis.

We investigate the possible effects of acupuncture on the improvement of neurological problems in HTLV-I-associated myelopathy/tropical spastic paraparesis (HAM/TSP)disease. Twenty patients with HAM/TSP were studied in this pre and post-test clinical trial. Urinary incontinence, global motor disability, spasticity, and pain severity were evaluated before, one month, and three-month after the intervention. Analyses demonstrated a significant reduction of urinary symptoms one month after acupuncture (P = 0.023). A significant improvement was observed in patients' pain and the spasticity at the upper extremity joints, one and three-month after the intervention (P < 0.05). This study suggests that body acupuncture can be used as a complementary treatment to improve HAM/TSP neurological symptoms.

Long-term disability after stroke in Iran: Evidence from the Mashhad Stroke Incidence Study.

BACKGROUND: Accurate information about disability rate after stroke remains largely unclear in many countries. Population-based studies are necessary to estimate the rate and determinants of disability after stroke. METHODS: Patients were recruited from the Mashhad Stroke Incidence Study and followed for five years after their index event. Disability was measured using the modified Rankin scale and functional dependency was measured using the Barthel index. RESULTS: Among 684 patients registered in this study, 624 were first-ever strokes. In total, 69.0% (n = 409) of patients either died or remained disabled at five-year follow-up. Among the first-ever stroke survivors, 18.5% (n = 69) at one year and 15.9% (n = 31) at five years required major assistance in their daily activities. Patients with a history of stroke (before the study period) compared with first-ever strokes were more likely to be disabled at one year (modified Rankin scale>2 in 40.0% vs. 19.1%; P < 0.001). Advanced age, severity of stroke at the time of admission, diabetes mellitus, and educational level (<12 years) were independently associated with greater disability and functional dependency. CONCLUSION: We found that significant disability and functional dependency after stroke in Northeast Iran were largely attributable to the effects of stroke severity and prior dependency.

Dobutamine stress-induced ischemic right ventricular dysfunction in patients with three-vessel coronary artery disease.

BACKGROUND: Dobutamine stress echocardiography (DSE) is a non-invasive technique to detect coronary artery diseases (CAD). There are limited studies on evaluation of the right ventricular function by stress echocardiography. The appropriate evaluation of RV function and early diagnosis of its failure can help to improve outcomes for the patients undergoing cardiac surgery. OBJECTIVE: To determine right ventricular dysfunction in patients with three-vessel CAD by using DSE. METHODS: This cross-sectional study was among 13 patients who were candidates for coronary artery bypass grafting (CABG) referred to Ghaem Hospital, Mashhad, Iran; from September 2015 to May 2016. After a physical examination and initial measures, DSE was performed and echocardiographic parameters were recorded by a cardiologist. Paired-samples t-test was performed using SPSS Software v.16.0 for data analysis. RESULTS: The study included 13 patients (9 males) with a mean age of 65.4±7.6 years. The mean of TAPS was 16.9±4.5 mm and 15.7±2.9 mm before and after stress echocardiography, respectively (p=0.69). Systolic right ventricular (SRV) peak increased from before DSE compared with after DSE (8.0±2.2 vs. 13.7±4.2 mm/s, p<0.001). In addition, after dobutamine injection, right ventricular (RV) cardiac output decreased in 7 patients and one patient was affected by post-ejection shortening. CONCLUSION: It seems that TAPS and RV cardiac output after injection of dobutamine, can be used as markers for the recognition of ischemic RV dysfunction.

Prediction of the ischemic origin of functional mitral regurgitation in patients with systolic heart failure through posterior mitral leaflet angle.

BACKGROUND: Differentiating ischemic from non-ischemic functional mitral regurgitationý (FMR) in patients with cardiomyopathy is important in terms of the therapeutic decision-making and prognosis, but might be clinically challenging. In this study, the deformation of mitral valve (MV) indices in the prediction of the etiology of FMR was assessed using 2D transthoracic and tissue Doppler echocardiography. METHODS: This case-control study was conducted from April 2015 to January 2016 in Imam Reza Hospital in Mashhad, Iran. The participants consisted of 40 patients with ischemic cardiomyopathy (ICM) and 22 with non-ischemic dilated cardiomyopathy (DCM) who referred to the heart failure clinic. Transthoracic echocardiography was performed using the conventional 2D and tissue Doppler imaging (TDI). MV tenting area (TA), coaptation distance (CD), anterior and posterior mitral leaflet angles (AMLA and PMLA), and regional systolic myocardial velocity (Sm) were measured. RESULTS: There were no significant differences in echocardiographic indices between the two groups, besides Sm and PMLA which were significantly lower and higher, respectively, in ICM subjects in comparison with DCM patients (P = 0.002). PMLA ≥ 40 degrees and Sm ≤ 4 cm/second have a relatively high value for discriminating the ischemic from non-ischemic origin of functional MR in subjects with systolic heart failure (sensitivity: 80.0% and 70.0%, specificity: 73.0% and 77.3%; P = 0.001 and P < 0.001; respectively). Multivariable logistic regression identified PMLA and anterior Sm as major determinants for ischemic MR {Odds ratio (OR) [95% confidence interval (CI)] = 0.89 (0.82-0.96), P = 0.003, OR (95% CI) = 0.29 (0.14-0.60), P = 0.001, respectively}. CONCLUSION: The present study showed that PMLA and Sm had an independent significant association with the mechanism of FMR. These findings are suggestive of the predictive role of mitral deformation echocardiographic indices in the determination of the etiology of FMR in systolic heart failure.

The Efficacy of Glasgow Coma Scale (GCS) Score and Acute Physiology and Chronic Health Evaluation (APACHE) II for Predicting Hospital Mortality of ICU Patients with Acute Traumatic Brain Injury.

OBJECTIVE: To compare the efficacy and functional outcome of Glasgow Coma Scale (GCS) score with that of Acute Physiology and Chronic Health Evaluation Score II (APACHE II) in patients with multiple trauma admitted to the ICU. METHODS: This cross-sectional study included 125 patients with traumatic brain injury associated with systemic trauma admitted to the ICU of Shahid Kamyab Hospital, Mashhad, between September 2015 and December 2016. On the day of admission, data were collected from each patient to calculate GCS and APACHE II scores. Sensitivity, specificity, and correct outcome prediction was compared between GCS and APACHE II. RESULTS: Positive predictive value (PPV) at the cut-off points was higher in APACHE II (80.6%) compared with GCS (69.2%). However, negative predictive value (NPV) of GCS was slightly higher in comparison with APACHE II. Moreover, the area under the receiver operating characteristic (ROC) curve for sensitivity and specificity of GCS and APACHE II showed no significant difference (0.81±0.04 vs. 0.83±0.04; p=0.278 respectively). CONCLUSION: Our study suggested that there was no considerable difference between GCS and APACHE II scores for predicting mortality in head injury patients. Both scales showed acceptable PPV, while APACHE II showed better results. However, the utilization of GCS in the initial assessment is recommended over APACHE II as the former provides higher time- and cost-efficiency.

Obstetrics and perinatal outcomes of dichorionic twin pregnancy following ART compared with spontaneous pregnancy.

INTRODUCTION: Regarding to the recent advances in assisted reproductive techniques (ART), twin and multiple pregnancies have increased during past years. OBJECTIVE: This study was performed to compare obstetrics and perinatal outcomes of dichorionic twin pregnancy following ART with spontaneous pregnancy. MATERIALS AND METHODS: In this cross-sectional study which was performed in Ghaem Hospital, Mashhad University of Medical Sciences, 107 dichorionic twin pregnancy were enrolled in two groups: spontaneous group (n=96) and ART group (n=31). Basic criteria and obstetrics and neonatal outcomes information including demographic data, gestational age, mode of delivery, pregnancy complications (preeclampsia, gestational diabetes, preterm labor, and intrauterine growth retardation (IUGR), postpartum hemorrhage), neonatal outcomes (weight, first and fifth minute Apgar score, Neonatal Intensive Care Unit (NICU) admission, mortality, respiratory distress, and icterus) were recorded using a questionnaire. RESULTS: Preterm labor, gestational diabetes, and preeclampsia were significantly higher in ART group compared to spontaneous pregnancy group. However, other factors such as anemia, IUGR, postpartum hemorrhage, and intrauterine fetal death (IUFD) were not significantly different between groups. There were no significant differences between groups in terms of neonatal outcomes (weight, 1(st) and 5(th) min Apgar score <7, NICU hospitalization, mortality, respiratory distress, and icterus). CONCLUSION: With regard of significantly higher poor outcomes such as preeclampsia, gestational diabetes and preterm labor in ART group, the couples should be aware of these potential risks before choosing ART.
