Abstract
Introduction The leuko-glycemic index (LGI), a combined index of patient leukocyte counts and blood glucose levels, has been shown to predict the prognosis of myocardial infarction (MI) patients. Our study aims to investigate the performance of LGI in prediction of outcomes in a population of diabetic and non-diabetic MI patients. Methods This observational registry-based cohort study was performed on acute myocardial infarction (AMI) patients. Participants were sub-grouped according to their diabetes status and the calculated optimal LGI cut-off value. The outcomes of the study were the length of hospital stay, and in-hospital and 30-day mortality. Results A total of 296 AMI (112 diabetic and 184 non-diabetic) patients were included in the study. The optimal cut-off value of LGI in the diabetic and non-diabetic groups was calculated as 2970.4 mg/dl.mm3 and 2249.4 mg/dl.mm3, respectively. High LGI was associated with increased hospital admission duration in non-diabetic patients (p = 0.017). The area under the curve (AUC) of LGI for prediction of in-hospital mortality was 0.93 (95% CI: 0.87 to 1.00) in the diabetic group and 0.92 (95% CI: 0.85 to 0.99) in the non-diabetic group. LGI had a sensitivity and specificity of 90.00%, and 93.14% in prediction of in-hospital mortality in the diabetic group compared to 77.77% and 90.85% in the non-diabetic group. We observed 4 post-discharge mortalities in our patient group. Conclusion Our study demonstrated that higher LGI predicts in-hospital mortality in both diabetic and non-diabetic patients, while the length of hospital stay was only predicted by LGI levels in non-diabetic patients.

Abstract
Introduction In recent years, studies have provided evidence on the prognostic value of the leuko-glycemic index (LGI) in acute myocardial infarction (MI), but there is a lack of consensus. In addition, various reported cut-offs for LGI have raised concern regarding its clinical applicability. So, to conclude, through this systematic review and meta-analysis, we aimed to investigate all available evidence on the prognostic value of LGI in acute MI. Methods Two independent researchers summarized records available in the four main databases of Medline (Via PubMed), Embase, Scopus, and Web of Science until 15 Sep 2022. Articles studying the prognostic value of the LGI in acute MI were included. Finally, sensitivity, specificity, prognostic odds ratio, and the area under the curve (AUC) for LGI were analyzed and reported. Results Eleven articles were included (3701 patients, 72.1% male). Based on the analyses, AUC, sensitivity, and specificity for LGI in prediction of mortality following acute MI were 0.77 (95% CI: 0.73 to 0.80), 0.75 (95% CI: 0.62 to 0.84), and 0.66 (95% CI: 0.51 to 0.78), respectively. Positive and negative post-test probability of LGI in prediction of mortality were 21% and 5%, respectively. AUC, sensitivity, and specificity for LGI in prediction of major cardiac complications after acute MI were 0.81 (95% CI: 0.77 to 0.84), 0.84 (95% CI: 0.70 to 0.92), and 0.64 (95% CI: 0.49 to 0.84), respectively. Also, the Positive and negative post-test probability of LGI in this regard were 59% and 13%, respectively. Conclusion Although the results demonstrated that the LGI could predict mortality and acute cardiac complication after MI, the low post-test probability of LGI in risk stratification of patients raises questions regarding its applicability. Nevertheless, as most of the available studies have been conducted in the Latino/Hispanic population, further evidence is warranted to generalize the validity of this tool to other racial populations.

Risk Factors of Readmission in COVID-19 Patients; a Retrospective 6-Month Cohort Study. ARCHIVES OF ACADEMIC EMERGENCY MEDICINE 2022; 10:e48. [PMID: 36033987 PMCID: PMC9397591 DOI: 10.22037/aaem.v10i1.1514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 11/16/2022]
Abstract
Introduction The available literature regarding the rate of readmission of COVID-19 patients after discharge is rather scarce. Thus, the aim in the current study was to evaluate the readmission rate of COVID-19 patients and the components affecting it, including clinical symptoms and relevant laboratory findings. Methods In this retrospective cohort study, COVID-19 patients who were discharged from Imam Hossein hospital, Tehran, Iran, were followed for six months. Data regarding their readmission status were collected through phone calls with COVID-19 patients or their relatives, as well as hospital registry systems. Eventually, the relationship between demographic and clinical characteristics and readmission rate was assessed. Results 614 patients were entered to the present study (mean age 58.7±27.2 years; 51.5% male). 53 patients were readmitted (8.6%), of which 47 patients (7.6%) had a readmission during the first 30 days after discharge. The reasons for readmission were relapse of COVID-19 symptoms and its pulmonary complications in 40 patients (6.5%), COVID-19 related cardiovascular complications in eight patients (1.3%), and non-COVID-19 related causes in five patients (0.8%). Older age (OR=1.04; 95% CI: 1.01, 1.06; p=0.002) and increased mean arterial pressure during the first admission (OR=1.04; 95% CI: 1.01, 1.08; p=0.022) were found to be independent prognostic factors for the readmission of COVID-19 patients. Conclusion Readmission is relatively frequent in COVID-19 patients. Lack of adequate hospital space may be the reason behind the early discharge of COVID-19 patients. Hence, to reduce readmission rate, extra care should be directed towards the discharge of older or hypertensive patients.

Comparison between surgery and fibrinolytic therapy in prosthetic valve thrombosis: A systematic review and meta-analysis. J Card Surg 2022; 37:2776-2785. [PMID: 35701901 DOI: 10.1111/jocs.16681] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 06/04/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Prosthetic valve thrombosis (PVT) is a rare but life-threatening complication. Surgery and fibrinolytic therapy (FT) are the two main treatment options for PVT. The choice between surgery and FT has always been a matter of debate. Previous studies have shown that although the mortality rate is higher in surgery, complications are less frequent than in FT. We aimed to perform a systematic review and meta-analysis to compare the results of surgery and FT in PVT. METHODS A systematic review of the literature was performed through Medline, Embase, Scopus, and Web of Science, encompassing all studies comparing surgery and FT in PVT. The rate of each complication and risk ratio (RR) of complications in surgery and FT were assessed using random-effects models. RESULTS Fifteen studies with 1235 patients were included in the meta-analysis. The pooled risk of the mortality was not significantly different between FT and surgery in patients with PVT (pooled RR = 0.78, 95% confidence interval [CI]: 0.38-1.60, I² = 61.4%). The pooled risks of thromboembolic events (pooled RR = 4.70, 95% CI: 1.83-12.07, I² = 49.6%) and major bleeding (pooled RR = 2.45, 95% CI: 1.09-5.50, I² = 41.1%) and PVT recurrence (pooled RR = 2.06 95% CI: 1.29-3.27, I² = 0.0%) were significantly higher in patients who received FT. CONCLUSION Surgery may be safer and with fewer complications than FT for PVT treatment. However, randomized clinical trials are needed to determine the proper treatment for PVT.

Is cardiac Troponin I Considered as A Predictor of In-hospital Mortality among COVID-19 Patients? A Retrospective Cohort Study. Bull Emerg Trauma 2022; 10:9-15. [PMID: 35155691 PMCID: PMC8818101 DOI: 10.30476/beat.2022.92719.1310] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 11/04/2021] [Accepted: 11/16/2021] [Indexed: 01/12/2023] Open
Abstract
Objective: To describe the levels of troponin I in COVID-19 patients and its role in the prediction of their in-hospital mortality as a cardiac biomarker. Methods: The current retrospective cohort study was performed on the clinical records of 649 COVID-19-related hospitalized cases with at leat one positive polymerase chain reaction (PCR) test in Tehran, Iran from February 2020 to early June 2020. The on admission troponin I level divided into two groups of ≤0.03ng/mL (normal) and >0.03ng/mL (abnormal). The adjusted COX-regression model was used to determine the relationship between the studied variables and patient’s in-hospital mortality. Results: In this study, the median age of subjects was 65 years (54.8% men) and 29.53% of them had abnormal troponin I levels. Besides, the in-hospital mortality rate among patients with abnormal troponin I levels was found to be 51.56%; whereas, patients with normal levels exhibited 18.82% mortality. Also, the multivariable analysis indicated that the risk of death among hospitalized COVID-19 patients displaying abnormal troponin I levels was 67% higher than those with normal troponin I levels (Hazard ratio=1.67, 95% confidence interval=1.08-2.56, p=0.019). Conclusion: It seems that troponin I is one of the important factors related to in-hospital mortality of COVID-19 patients. Next, due to the high prevalence of cardiac complications in these patients, it is highly suggested to monitor and control cardiac biomarkers along with other clinical factors upon the patient’s arrival at the hospital.

Abstract
BACKGROUND Dual antiplatelet therapy (DAPT) in patients with MI who are candidates for early coronary artery bypass grafting (CABG) can affect intraoperative and postoperative outcomes. Therefore, the aim of this study was to evaluate the effect of DAPT up to the day before CABG on the outcomes during and after surgery in patients with MI. METHODS In this prospective cohort study, 224 CABG candidate patients with and without MI were divided into two groups: (A) patients without MI who were treated with aspirin 80 mg/day before surgery (noMI-aspirin group; n = 124) and (B) patients with MI who were treated with aspirin 80 mg/day before surgery and clopidogrel (Plavix brand) at a dose of 75 mg/day (MI-DAPT group; n = 120). Dual or mono-antiplatelet therapy continued until the day before surgery. Patients were followed to assess in-hospital and 6-months outcomes. RESULTS The in-hospital mortality in MI-DAPT group was similar with noMI-aspirin group (OR 4.2; 95% CI 0.9-20.5; p = 0.071). The prevalence of CVA (p = 0.098), duration of hospital stay (p = 0.109), postoperative ejection fraction level (p = 0.693), diastolic dysfunction grade (p = 0.651) and postoperative PAP level (p = 0.0364) did not show difference between two groups. No mild or severe bleeding was observed in the patients. Six-month follow up showed that number of readmissions (p = 0.801), number of cases requiring angiography (p = 0.100), cases requiring re-PCI (p = 0.156), need for re-CABG (p > 0.999) and CVA (p > 0.999) did not differ between the two groups. During the 6-month follow-up, out-hospital mortality did not differ significantly between the two groups (p = 0.446). CONCLUSIONS A 6-month follow-up showed that DAPT with aspirin and clopidogrel before CABG in patients with MI has no effect on postoperative outcomes more than mono-APT with aspirin. Therefore, DAPT is recommended in the preoperative period for these patients.

Abstract
INTRODUCTION Currently, the basis of acute coronary syndrome (ACS) therapy is dual antiplatelet therapy (DAPT) with Aspirin as a nonsteroidal anti-inflammatory drug and clopidogrel as adenosine diphosphate receptor antagonists. Therefore, the aim of the present systematic review is to answer that should DAPT with Aspirin and clopidogrel be continued until coronary artery bypass grafting (CABG) in patients who have ACS? METHODS The search for relevant studies in the present meta-analysis is based on three approaches: A) systematic searches in electronic databases, B) manual searches in Google and Google Scholar, and C) screening of bibliography of related original and review articles. The endpoints included mortality rate, myocardial infarction (MI), cerebrovascular accident (CVA), reoperation, re-exploration, other cardiac events, renal failure, length of ICU and hospital stay, chest tube drainage and blood product transfusion after CABG. RESULTS After the initial screening, 41 articles were studied in detail, and finally the data of 15 studies were included in the meta-analysis. DAPT before CABG in patients with ACS does not increase the rate of mortality, CVA, renal failure, MI, and other cardiac events, but increases reoperation, re-exploration, length of ICU, and hospital stay. Chest tube drainage and blood product transfusion rate significantly increased in the DAPT group compared to the control group (non-antiplatelet or Aspirin alone). Increase in chest tube drainage and blood product transfusion rate indicates an increase in bleeding, so increase in reoperation, re-exploration to control bleeding, and, subsequently, increase in the length of ICU and hospital stay are expected. CONCLUSIONS DAPT with Aspirin and clopidogrel before CABG in patients with ACS does not increase the rate of mortality, CVA, renal failure, MI, and other cardiac events despite more bleedings, and it may be suggested before CABG for better graft patency.

Abstract
INTRODUCTION Amphetamine type stimulants (ATS) such as amphetamine and methamphetamine (MA) are one of the most important causes of poisoning in the world. In this study we aimed to define the predictive factors of mortality in acute ATS poisoning patients. METHODS This is a retrospective cross-sectional study on all cases with acute ATS poisoning who were referred to a referral center for poisoning, Tehran, Iran, from April 2011 to March 2014. Using patients' medical records, demographic data, route of exposure, type and amount of ATS, the cause of poisoning, clinical presentations, and electrocardiogram (ECG) and laboratory findings, as well as patient's outcomes were collected and analyzed regarding the independent predictive factors of mortality. RESULTS 226 cases with the mean age of 32.9 ± 10.9 years were studied (77% male). MA was the most abused ATS (97.4%) and the most frequent route of exposure was oral (55.3%). The mortality rate was 5.4%. There was a significant association between agitation (p = 0.002), seizure (p = 0.001), loss of consciousness (p < 0.001), creatine phosphokinase level (p = 0.002), serum pH (p = 0.002), serum HCO3 (p = 0.02), and PCO2 (p = 0.01) with mortality. However, serum HCO3 [OR=1.27 (95% CI: 1.07-1.50); p value=0.005], PCO2 [OR=0.89 (95% CI: 0.84-0.96); p value=0.002], and loss of consciousness [OR=0.019 (95% CI: 0.003-0.106); p value=0.000] were the only independent predictive factors of mortality. CONCLUSION PCO2 ≥ 51 mmHg, serum bicarbonate ≤ 22.6 mEq/L, and loss of consciousness on admission could be considered as prognostic factors of mortality in acute ATS poisoning cases presenting to emergency department.

Abstract
SummaryAim: To perform a meta-analysis of published data on the prevalence and risk of malignancy of focal thyroid incidental uptake (FTIs) detected by Fluorine-18-Fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) or PET/CT. Methods: A comprehensive literature search of studies published up to and including December 2012 was performed. Pooled prevalence and malignancy risk of FTIs were calculated, including a sub-analysis for the geographic areas of origin of the studies. Results: 34 studies including 215 057 patients were selected. Pooled prevalence of FTIs was 1.92% (95% confidence interval [95%CI]: 1.87–1.99%). Overall, 1522 FTIs underwent histopathology evaluation. Pooled risk of malignancy was 36.2% (95%CI: 33.8–38.6%), without significant differences among various geographic areas. Conclusions: FTIs are observed in about 2% of 18F-FDG-PET or PET/CT scans and carry a significant risk of malignancy. Therefore, further investigation is warranted whenever FTIs are detected by 18F-FDG-PET or PET/CT.

Abstract
Previous research on the equine major histocompatibility complex (MHC) demonstrated strong correlations between haplotypes defined by polymorphic intra-MHC microsatellites and haplotypes defined using classical serology. Here, we estimated MHC diversity in a sample of 124 Arabian horses from an endangered strain native to Iran (Persian Asil Arabians), using a validated 10-marker microsatellite panel. In a group of 66 horses related as parent-offspring pairs or half-sibling groups, we defined 51 MHC haplotypes, 49 of which were new. In 47 of the remaining 58 unrelated horses, we could assign one previously identified MHC haplotype, and by default, we gave provisional haplotype status to the remaining constellation of microsatellite alleles. In these horses, we found 21 haplotypes that we had previously defined and 31 provisional haplotypes, two of which had been identified in an earlier study. This gave a total of 78 new MHC haplotypes. The final 11 horses were MHC heterozygotes that we could not phase using information from any of the previously validated or provisional haplotypes. However, we could determine that these horses carried a total of 22 different undefined haplotypes. In the overall population sample, we detected three homozygous horses and one maternally inherited recombinant from 21 informative segregations. Virtually all of the horses tested were MHC heterozygotes, and most unrelated horses (98%) were heterozygous for rare microsatellite-defined haplotypes found less than three times in the sampled horses. This is evidence for a very high level of MHC haplotype variation in the Persian Asil Arabian horse.

ASQ-3 scores are sensitive to small differences in age in a Peruvian infant population. Child Care Health Dev 2017; 43:556-565. [PMID: 28480511 DOI: 10.1111/cch.12469] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2016] [Revised: 04/01/2017] [Accepted: 04/03/2017] [Indexed: 11/27/2022]
Abstract
OBJECTIVE The Ages and Stages Questionnaires Edition 3 (ASQ-3) are a well-validated international screen for developmental delays in young children. However, previous studies demonstrate variable scores between children eligible to take the same ASQ-3 interval. This study aimed to determine a relationship between age and ASQ-3 score for each screening interval. METHODS This was a baseline exploratory cross-sectional study of infants under 2 years old evaluated for the Peruvian social programme Cuna Más. Participants were included in Cuna Más if they lived in districts with fewer than 2000 inhabitants or 400 homes, indicating a predominantly rural population. The appropriate ASQ-3 screening interval was administered to each subject. Subjects were divided into four 2-week chronological subgroups based on age within each 2-month screening window and aggregated across all 12 screening intervals. Fisher's exact test, analysis of variance and Bonferonni post hoc test were used to compare differences between age subgroups. Linear regression was performed to assess the relationship between ASQ-3 score and both aggregated and disaggregated age subgroup. RESULTS A total of 5850 Peruvian infants were evaluated in 2013. Mean age was 13 ± 6.6 months, 50.7% were male and mean maternal education was 6.6 ± 4.0 years; 34.8% infants were stunted, 7.8% were underweight, 0.9% were wasted and 2% had age adjusted greater than 35 days for prematurity for ASQ-3 interval assignment. Mean total ASQ-3 was 42.2 ± 8.2. The ASQ-3 allocated 49.6% with suspected delay in one or more developmental areas. Before and after adjusting for wealth quintile, maternal education level, infant nutritional status and prematurity adjustment, age subgroup remained significantly associated with total ASQ-3 score (β = 1.8, CI: 1.7-2.0, P < 0.001), sectional ASQ-3 score (all P < 0.001) and inversely associated with one or more scores indicating suspected developmental delay (P < 0.001). CONCLUSIONS The ASQ-3 may underestimate the sensitivity of child development to small differences in age in this population.

Abstract
Fibromuscular Dysplasia (FMD) is a sporadic non-atherosclerotic disease. FMD has been established in nearly every arterial bed. However, the most frequent arteries affected are the renal and carotid arteries. Disease presentation may vary broadly, depending upon the arterial bed complication and the severity of illness. Hypertension, particularly resistant type, headache and dizziness are the most common presentations. String of beads appearance in angiographic views due to post-stenotic aneurysms is the characteristic view. It is most commonly described in young aged females; but in rare male cases has also been reported. Moreover, balloon angioplasty is standard and effective therapy for FMD. We present a young 28-year-old man who was referred for evaluation of resistant hypertension for nearly 3 years without comprehensive workup. The patient underwent renal artery angiography which confirmed beading narrowing of the right renal artery with significant stenosis at mid portion compatible with FMD; and balloon angioplasty was done. This case highlights that FMD should be kept in mind as a rare cause of resistant hypertension in young males; although it is most common in young females.

Abstract
This study evaluated the efficacy of red clover to relieve hot flashes and menopausal symptoms in peri/postmenopausal women. Electronic databases (MEDLINE, Scopus and the Cochrane Library) were searched. The mean frequency of hot flashes in red clover groups was lower compared with that in the control groups (close to statistical significance). Difference in means (MD) of hot flashes frequency was - 1.99 (- 4.12-0.139; p = 0.067; heterogeneity P > 0.01; I(2) = 94.93%; Random effect model). Subjective (vaginal dryness) and objective (maturation value) symptoms of vaginal atrophy showed a significant improvement with 80-mg dose of red clover. Red clover showed less therapeutic effect on psychology status, sexual problems and sleeping disorders. Red clover consumption may decrease frequency of hot flashes, especially in women with severe hot flashes (≥ 5 per day). Red clover may reduce other menopausal symptoms. Further trials are needed to confirm the current systematic review findings.

Abstract
Vaginal atrophy is a common complaint among many women in their menopause, presenting with a cluster of symptoms including dryness, itching, burning/soreness, discharge, irritation and painful intercourse. We searched for existing pertinent data in three chief registries. Specified time brackets included 1996-2013 for Medline, 1990-2013 for Scopus and 2013 for Cochrane Central Register of Controlled Trials (issue 1). Of 110 potentially relevant publications, 17 and 9 trials (7 on maturation value and 2 on vaginal dryness) were selected for qualitative and quantitative analysis, respectively. In general, soy isoflavones seem to improve vaginal symptoms as opposed to control arms. Soy isoflavones were also shown to be more efficacious in quantitative analysis, though this was statistically non-significant. Standardised difference in means of maturation value change was 0.072 (95% confidence interval [CI]: - 0.42 to 0.57), p = 0.777; heterogeneity P = 0.00; I(2) = 85.15%. Difference in means of vaginal dryness was - 0.204 (95% CI: - 0.28 to - 0.126), p < 0.001; heterogeneity P = 0.423; I(2) = 0.00. Soy isoflavones may relieve vaginal symptoms during menopause; nevertheless beneficial effects still remain uncertain due to possible publication bias or vast heterogeneity of the selected studies. Further studies with consistency in design as well as statistics are warranted.

Abstract
Aluminium phosphide (ALP) is one of the most commonly used pesticides worldwide with high mortality rates. Cellular damage and cardiorespiratory failure are the most common causes of mortality and morbidity after poisoning. It is supposed that giving enough time to the patient to survive, the most critical hours after exposure may help the cardiovascular system to recover itself and save the patient's life. During a training workshop for medical extracorporeal membrane oxygenation (ECMO), a 28-year-old ALP-poisoned male was referred to us. Fifty minutes after admission, he developed hypotension and bradycardia and was transferred to ICU. On the second venous blood gas, he had severe metabolic acidosis. After starting the patient on the routine treatment of ALP poisoning, he was a candidate for veno-arterial (VA) ECMO. After three days, lactate level decreased and his general condition improved. On day four, the patient was completely separated from the ECMO machine with acceptable echocardiography and ejection fraction of 40%. One day later, he was extubated, sent to the ward and subsequently discharged in good condition. We suggest this method of treatment for severe ALP poisoning as well as any other poisoning that causes cell toxicity and abrupt cardiovascular or respiratory failure.

Prevalence, main determinants, and early outcome of patients with atrial fibrillation hospitalized with ischemic stroke: evaluation of the value of risk assessment scores for predicting risk of stroke or major bleeding following anticoagulation therapy. ACTA BIO-MEDICA : ATENEI PARMENSIS 2015; 86:162-169. [PMID: 26422431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 01/03/2015] [Revised: 02/04/2015] [Accepted: 02/05/2015] [Indexed: 06/05/2023]
Abstract
BACKGROUND Despite controllable nature of atrial fibrillation in most patients, it increases the risk of atrial thrombosis leading to ischemic stroke. The researchers assessed the underlying risk factors for brain stroke and also major bleeding in patients with ischemic stroke and atrial fibrillation. METHODS Among 900 patients hospitalized with the diagnosis of ischemic brain stroke between 2013 and 2014, 100 patients had atrial fibrillation that included into this cross-sectional study. The risk of stroke and major bleeding was assessed using CHA2DS2-VASc and HAS-BLED risk scores, respectively; but new stroke was not considered. RESULTS Of 900 patients with evidences of ischemic stroke, 100 had atrial fibrillation with an overall prevalence of 11.1%. Mean CHA2DS2-VASc score was 4.35 ± 1.76 that the total score was ≥ 2 points in 93% of subjects showing necessity to anticoagulation therapy in 93% of the patients before recent stroke. Mean HAS-BLED score was 2.83 ± 1.30 that was ≥ 3 in 61% indicating risk of bleeding in 61% of all patients. 31% of the patients had previous history of atrial fibrillation, but only less than half of them (51%) were under treatment with warfarin, and also the measured INR was lower than the therapeutic range in 95.5% of individuals on warfarin therapy. In-hospital mortality was reported in 9% of all study subjects. The main determinants of early mortality included history of stroke, renal failure, presence of coronary artery disease, acetylsalicylic acid use, and Clopidogrel use. The analysis using the ROC curve showed that both CHA2DS2-VASc score (AUC = 0.788) and HAS-BLED score (AUC = 0.960) could strongly predict in-hospital mortality. CONCLUSION The patients with atrial fibrillation hospitalized with ischemic stroke showed an important absolute risk of further stroke and early mortality. Despite substantiated advantages of warfarin prophylaxis, its limited application is still very common.

Abstract
Current systematic review evaluated the efficacy of topical isoflavones to relieve vaginal symptoms in menopausal women. MEDLINE (1966 to January 2014), Scopus (1990 to January 2014), and the Cochrane Central Register of Controlled Trials (The Cochrane Library issue 1, 2013) were searched using keywords 'isoflavone and vagina'. Relevant studies were reviewed by two independent reviewers. Only randomised controlled trials (RCTs) were included in the systematic review. Out of 115 potentially relevant publications, four studies met the inclusion criteria. Topical isoflavones showed beneficial effects on dyspareunia, vaginal dryness and maturation value. Based on only one trial, the result of conjugated equine oestrogen cream (0.3 mg/day) was similar to use of isoflavone vaginal gel and superior to that of placebo gel. However, drawing any definite conclusion was difficult because of the limited number of RCTs, the small sample sizes, weak methodology and considerable heterogeneity of the included studies.

Abstract
This randomized-controlled trial investigated the effect of physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. Results of this study on 120 male and female volunteers showed that an 8-week group physical exercise programme was significantly effective in older adults' happiness. Findings showed that physical exercise programme is so beneficial for increasing older adults' happiness. Physical activity is associated with well-being and happiness. The purpose of this study was to determine the effects of an 8-week long physical exercise programme (PEP) on happiness among older adults in Nowshahr, Iran. This was a randomized control trial study. The participants consisted of a group of 120 male and female volunteers (mean ± SD age: 71 ± 5.86 years) in a convenience sampling among older adults in public parks in Nowshahr, Iran. We randomly allocated them into experimental (n = 60) and control (n = 60) groups. A validated instrument was used to measure well-being and happiness [Oxford Happiness Inventory (OHI)]. Respondents were asked to complete the OHI before and 2 months after implementing PEP. The 8-week PEP was implemented with the intervention group. The statistical analysis of the data was conducted using paired t-test, Fisher's exact test and χ(2). Before the intervention, there was no significant difference in the happiness mean score between the case and control groups; however, after implementing PEP, happiness significantly improved among the experimental group (P = 0.001) and did not improve within the control group (P = 0.79). It can be concluded that PEP had positive effects on happiness among older adults. Planning and implementing of physical activity is so important for older happiness.

The effects of different doses of atorvastatin on serum lipid profile, glycemic control, and liver enzymes in patients with ischemic cerebrovascular accident. ARYA ATHEROSCLEROSIS 2014; 10:298-304.

Abstract
BACKGROUND Despite established effects of atorvastatin on level of serum lipid profile in patients with different underlying clinical conditions, the effects of this drug on other serum biomarkers remain uncertain. We examined the effects of atorvastatin therapy on lipid profile, glycemic control, and liver enzymes in patients with ischemic cerebrovascular accident without any history or clinical evidences of diabetes, heart failure, renal failure, or hepatic disease. METHODS In a randomized double-blinded controlled trial, 140 hospitalized patients with an ischemic cerebrovascular accident were included and randomly assigned to receive either atorvastatin 40 mg (n = 70) or atorvastatin 20 mg daily (n = 70) for 3 months. The levels of biomarkers were measured at the time of administrating drugs as well as at the time of completing the treatment. RESULTS A significant reduction was revealed in serum triglyceride, total cholesterol, low-density lipoprotein, non-high-density lipoprotein (HDL) cholesterol, and also aspartate aminotransferase levels as well as a significant increase in serum HDL level following administration of atorvastatin in both case and control groups who received the atorvastatin 40 mg/day and 20 mg/day, respectively (all P < 0.050). Although a significant increase in fasting blood sugar and hemoglobin A1c was observed in the case group received atorvastatin 40 mg/day (both P < 0.001), but this elevation was not occurred in another group treated with lower dose of the drug (both P > 0.050). CONCLUSION Daily administration of 20 mg and 40 mg doses of atorvastatin for 3 months provides improvement in serum lipid profiles; however, because of interfering effect of high-dose atorvastatin on glycemic control status, the use of the former dose may be preferred. This is very important in these patients because the positive effects of high-dose atorvastatin in stroke patients are not confirmed.

Abstract
BACKGROUND We reviewed the available literature on the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers. METHODS MEDLINE and Scopus were searched by using "sentinel AND (cervix OR cervical)" as key words. Studies evaluating the accuracy of sentinel node mapping in the lymph nodal staging of uterine cervical cancers were included if enough data could be extracted for calculation of detection rate and/or sensitivity. RESULTS Sixty-seven studies were included in the systematic review. Pooled detection rate was 89.2% [95% CI: 86.3-91.6]. Pooled sensitivity was 90% [95% CI: 88-92]. Sentinel node detection rate and sensitivity were related to mapping method (blue dye, radiotracer, or both) and history of pre-operative neoadjuvant chemotherapy. Sensitivity was higher in patients with bilaterally detected pelvic sentinel nodes compared to those with unilateral sentinel nodes. Lymphatic mapping could identify sentinel nodes outside the routine lymphadenectomy limits. CONCLUSION Sentinel node mapping is an accurate method for the assessment of lymph nodal involvement in uterine cervical cancers. Selection of a population with small tumor size and lower stage will ensure the lowest false negative rate. Lymphatic mapping can also detect sentinel nodes outside of routine lymphadenectomy areas providing additional histological information which can improve the staging. Further studies are needed to explore the impact of sentinel node mapping in fertility sparing surgery and in patients with history of neoadjuvant chemotherapy.

Abstract
AIM To perform a systematic review and meta-analysis of published data on the prevalence and risk of malignancy of prostatic incidental uptake (PIU) detected by fluorine-18-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET) or PET/computed tomography (PET/CT). PATIENTS, MATERIAL, METHODS A comprehensive literature search of studies published up to February 2014 was performed. Pooled prevalence and malignancy risk of PIU were calculated on a per patient-based analysis including 95% confidence interval (95%CI). Furthermore, we assessed some parameters as potential predictors of malignant PIU. RESULTS Six studies including 47925 patients who underwent 18F-FDG PET/CT were selected. Pooled prevalence of PIU was 1.8% (95%CI: 1.3-2.3%). Overall, 444 patients with PIU were further evaluated and 121 underwent biopsy. The pooled risk of malignancy in patients with PIU further evaluated or verified by biopsy were 17% (95%CI: 12-23%) and 62% (95%CI: 54-71%), respectively. A higher mean age was observed in the group of malignant PIUs compared to benign PIUs. There was a trend towards a higher mean SUV(max) in the group of malignant PIUs but without a statistically significant difference compared to benign PIUs. Peripheric site of PIU but not presence or absence of calcification was a predictor of malignancy. CONCLUSIONS PIU is observed in about 1.8% of 18F-FDG PET/CT scans performed in male patients carrying a significant risk of malignancy. Therefore, whenever a PIU is detected further investigation is warranted to exclude malignancy, in particular when PIU is located in the peripheric site of prostate gland.

Abstract
BACKGROUND The primary objective of primary percutaneous coronary intervention (pPCI) in patients with acute ST-segment elevation myocardial infarction (STEMI) is not only to restore the blood flow in the infarct-related artery, but also to save the patients' quality and duration of their life. Since left ventricular ejection fraction (LVEF) is a known predictor of clinical outcomes in STEMI patients, the possible association between characteristics of a large group of patients who undergo pPCI with LVEF and death was evaluated. METHODS This prospective cohort study included 304 patients who had undergone pPCI between 2009 and 2011. The association between LVEF and in-hospital outcomes of patients was assessed. RESULTS LVEF ≤ 25%, 25% < LVEF < 50%, and LVEF ≥ 50% were presented in 23 (7.6%), 150 (49.3%), and 128 (42.1%) of the patients, respectively. Three patients (0.01%) died before echocardiography. There was no significant difference among aforementioned three groups regarding baseline characteristics, except age (P = 0.012) and sex (P = 0.016). Cumulative number of cardiogenic shock and death were 7 (2.3%) and 22 (7.2%), respectively; with significant differences between three LVEF groups. Age more than 70 years old, pulmonary edema, systolic blood pressure < 100 mm Hg, shock, post-PCI thrombolysis in myocardial infarction (MI) flow grade, corrected thrombolysis in MI frame count, angiographic success and ST-segment resolution showed significant association with death (P < 0.050). CONCLUSION This study not only demonstrates that LVEF ≤ 50% is associated with a higher incidence of in-hospital adverse events, but also identifies characteristics that are strongly correlated with the risk of LVEF ≤ 50% and death after pPCI.

Abstract
AIM Suppressive therapy with levothyroxine is the main step in treatment of differentiated thyroid cancer (DTC). However, subclinical hyperthyroidism is associated with deleterious effects on cardiovascular and skeletal systems. Metformin may have a suppressive effect on TSH level. METHODS We performed a single blind randomized controlled trial on the effect of short term Metformin therapy on 50 non-diabetic patients with DTC (mean age of 39.68 ±8.7 years) under suppressive therapy with levothyroxine. Metformin (500 mg) or placebo was added to the drug regimen of the patients and levothyroxine dose decreased by 33%. TSH and thyroid hormone values were measured at the beginning of the study and 3 months after treatment. RESULTS Forty-six patients had papillary and 4 had follicular carcinoma. The mean dose of levothyroxine was 2.2±0.48 µg/kg. The mean TSH level at the beginning of the study was 0.05±.04 mIU/L. The mean age, weight and baseline TSH level was not significantly different between metformin and placebo groups (P>0.2). In the metformin group, the mean (±SD) TSH level was significantly increased from 0.03±0.04 to 3.1±5.7 mIU/L after 3 months of intervention (P=0.01) and the mean thyroid hormone levels were significantly decreased (P<0.001). In the placebo group, the mean TSH level increased from 0.04±0.04 to 3.1±4.7 mIU/L after 3 months (P=0.003). Delta TSH was 3.0±5.6 mIU/L and 3.1±4.7 mIU/L in metformin and placebo groups, respectively (P=0.9). CONCLUSION Adding 500 mg of metformin to drug regimen was not useful to compensate for 33% of levothyroxine dose reduction in patients with DTC.

Thrombolytic-plus-Anticoagulant Therapy versus Anticoagulant-Alone Therapy in Submassive Pulmonary Thromboembolism (TVASPE Study): A Randomized Clinical Trial. J Tehran Heart Cent 2014; 9:104-8. [PMID: 25870626 PMCID: PMC4393831] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2014] [Accepted: 04/25/2014] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND The use of thrombolytic agents in the treatment of hemodynamically stable patients with acute submassive pulmonary embolism (PTE) remains controversial. We, therefore, conducted this study to compare the effect of thrombolytic plus anticoagulation versus anticoagulation alone on early death and adverse outcome following submassive PTE. METHODS We conducted a study of patients with acute pulmonary embolism and pulmonary hypertension or right ventricular dilatation/dysfunction but without arterial hypotension or shock. The patients were randomly assigned in a single-blind fashion to receive an anticoagulant [Enoxaparin (1 mg/kg twice a day)] plus a thrombolytic [Alteplase (100 mg) or Streptokinase (1500000 u/2 hours)] or an anticoagulant [Enoxaparin (1 mg/kg twice a day)] alone. The primary endpoint was in-hospital death or clinical deterioration requiring an escalation of treatment. The secondary endpoints of the study were major bleeding, pulmonary hypertension, right ventricular dilatation at the end of the first week, and exertional dyspnea at the end of the first month. RESULTS Of 50 patients enrolled, 25 patients were randomly assigned to receive an anticoagulant plus a thrombolytic and the other 25 patients were given an anticoagulant alone. The incidence of the primary endpoints was significantly higher in the anticoagulant-alone group than in the thrombolytic-plus-anticoagulant group (p value = 0.022). At the time of discharge, pulmonary artery pressure was significantly higher in the anticoagulant-alone group than in the thrombolytic-plus-anticoagulant group (p value = 0.018); however, reduction in the right ventricular size or normalization of the right ventricle showed non-significant differences between the two groups. There was no significant difference regarding the New York Heat Association (NYHA) functional class between the two groups at the end of the first month (p value = 0.213). No fatal bleeding or cerebral bleeding occurred in the patients receiving an anticoagulant plus a thrombolytic. CONCLUSION When given in conjunction with anticoagulants, thrombolytics may improve the clinical course of stable patients who have acute submassive pulmonary embolism and prevent clinical deterioration.
