Modified Glasgow Prognostic Score Predicted High-Grade Intracoronary Thrombus in Acute Anterior Myocardial Infarction

High-grade intracoronary thrombus (ICT) burden leads to greater myocardial injury following anterior myocardial infarction (MI). The modified Glasgow prohgnostic score (mGPS) is a novel immune-inflammatory index, calculated by using C-reactive protein (CRP) and albumin levels, was shown to have prognostic value in heart diseases. The present study investigated the role of mGPS in predicting high grade ICT in patients with acute anterior MI admitted between February 2017 and March 2020. Blood samples were obtained at admission and mGPS was calculated. The ICT burden was evaluated visually from angiographic images. Patients were divided into 2 groups according to the ICT burden as high and low. A total of 1132 patients were enrolled: a mean age 61 ± 12.4 years and 370 males (32.7%). Serum albumin was lower, whereas mGPS and CRP were higher in high grade ICT group. CRP (odds ratio (OR): 1.404 95% CI: 1.312-1.502; P < .001), albumin (OR: .486; 95% CI: .301-.782 P < .001), and mGPS (0 vs ≥ 1) (OR: 7.391; 95% CI: 3.910-13.972; P < .001) were independent predictors of high-grade ICT burden in the left anterior descending coronary artery. The mGPS is a novel predictor of high-grade ICT burden and may be useful for risk stratification in patients with acute anterior MI.

Baseline Characteristics of a Patient Cohort and Predictors of In-hospital MORtality in CORonary Care Units (MORCOR-TURK) Trial in Türkiye

OBJECTIVE

The MORtality in CORonary Care Units in Türkiye (MORCOR-TURK) trial is a national registry evaluating predictors and rates of in-hospital mortality in coronary care unit (CCU) patients in Türkiye. This report describes the baseline demographic characteristics of patients recruited for the MORCOR-TURK trial.

METHODS

The study is a multicenter, cross-sectional, prospective national registry that included 50 centers capable of 24-hour CCU service, selected from all seven geographic regions of Türkiye. All consecutive patients admitted to CCUs with cardiovascular emergencies between September 1-30, 2022, were prospectively enrolled. Baseline demographic characteristics, admission diagnoses, laboratory data, and cardiovascular risk factors were recorded.

RESULTS

A total of 3,157 patients with a mean age of 65 years (range: 56-73) and 2,087 (66.1%) males were included in the analysis. Patients with arterial hypertension [1,864 patients (59%)], diabetes mellitus (DM) [1,184 (37.5%)], hyperlipidemia [1,120 (35.5%)], and smoking [1,093 (34.6%)] were noted. Non-ST elevation myocardial infarction (NSTEMI) was the leading cause of admission [1,187 patients (37.6%)], followed by ST elevation myocardial infarction (STEMI) in 742 patients (23.5%). Other frequent diagnoses included decompensated heart failure (HF) [339 patients (10.7%)] and arrhythmia [272 patients (8.6%)], respectively. Atrial fibrillation (AF) was the most common pathological rhythm [442 patients (14%)], and chest pain was the most common primary complaint [2,173 patients (68.8%)].

CONCLUSION

The most common admission diagnosis was acute coronary syndrome (ACS), particularly NSTEMI. Hypertension and DM were found to be the two leading risk factors, and AF was the most commonly seen pathological rhythm in all hospitalized patients. These findings may be useful in understanding the characteristics of patients admitted to CCUs and thus in taking precautions to decrease CCU admissions.

The relationship of the hemoglobin to serum creatinine ratio with long-term mortality in patients with acute coronary syndrome: A retrospective study

Acute coronary syndrome (ACS) is an urgent clinical condition of cardiovascular diseases. The present study evaluated the predictive efficacy of the hemoglobin to serum creatinine ratio (Hgb/Cr) on long-term mortality in patients with ACS. The ratio, representing the proportion of the 2 values, is cheap, practical, and very easy to calculate at the bedside. Our study included 475 patients who were admitted to the coronary intensive care unit with a diagnosis of ACS and who underwent coronary angiography. The Hgb/Cr ratio was calculated by dividing the admission hemoglobin by the admission serum creatinine. All patient data were collected from the electronic hospital information system, patient files, and the hospital's archive. A comparison of the patients laboratory findings revealed that the Hgb/Cr ratios differed significantly between the survivor and non-survivor group [16.6 (7.7-49) vs 13.8 (4.91-32.8), respectively; P < .001]. A univariate Cox regression analysis showed that the Hgb/Cr ratio was statistically significant in predicting long-term mortality (0.836; 95% confidence interval [CI]: 0.781-0.895; P < .001). After adjusting the model by adding clinically and statistically significant variables, the Hgb/Cr ratio was still an independent predictor of long-term mortality (0.886; 95% CI: 0.815-0.963; P = .004). The Hgb/Cr ratio's discriminant ability was tested with an receiver operating characteristic curve analysis. The Hgb/Cr ratio's area under the curve value was 0.679 (95% CI: 0.609-0.750; P < .001). A survival analysis using the Kaplan-Meier curve of the 2 Hgb/Cr ratio groups (according to cutoff value) revealed that the low-Hgb/Cr group had a significantly higher mortality rate than high-Hgb/Cr group. The Hgb/Cr ratio was found to be an independent predictor of long-term mortality in ACS patients.

Rationale, Design, and Methodology of the MORCOR-TURK Trial: Predictors of In-hospital MORtality in CORonary Care Patients in Turkey

BACKGROUND

Coronary care units are sophisticated clinics established to reduce deaths due to acute cardiovascular events. Current data on coronary care unit mortality rates and predictors of mortality in Turkey are very limited. The MORtality predictors in CORonary care units in TURKey (MORCOR-TURK) trial was designed to provide information on the mortality rates and predictors in patients followed in coronary care units in Turkey.

METHODS

The MORCOR-TURK trial will be a national, observational, multicenter, and noninterventional study conducted in Turkey. The study population will include coronary care unit patients from 50 centers selected from all regions in Turkey. All consecutive patients admitted to coronary care units with cardiovascular diagnoses between 1 and 30 September 2022 will be prospectively enrolled. All data will be collected at one point in time, and the current clinical practice will be evaluated (ClinicalTrials.gov number NCT05296694). In the first step of the study, admission diagnoses, demographic characteristics, basic clinical and laboratory data, and in-hospital management will be assessed. At the end of the first step, the predictors and rates of in-hospital mortality will be documented. The second step will be in cohort design, and discharged patients will be followed up till 1 year. Predictors of short- and long-term mortality will be assessed. Moreover, a new coronary care unit mortality score will be generated with data acquired from this cohort.

RESULTS

The short-term outcomes of the study are planned to be shared by early 2023.

CONCLUSION

The MORCOR-TURK trial will be the largest and most comprehensive study in Turkey evaluating the rates and predictors of in-hospital mortality of patients admitted to coronary care units.

Predictive outcomes of APACHE II and expanded SAPS II mortality scoring systems in coronary care unit

OBJECTIVE

We investigated the predictive values of the expanded Simplified Acute Physiology Score (SAPS) II and Acute Physiologic Score and Chronic Health Evaluation (APACHE) II score in predicting in-hospital mortality in coronary care unit (CCU) patients.

METHODS

In this study, expanded SAPS II and APACHE II scores were calculated in the CCU of a single-center tertiary hospital. Patients admitted to CCU with any cardivascular indication were included in the study. Both scores were calculated according to previously determined criteria. Calibration and discrimination abilities of the scores in predicting in-hospital mortality were tested with Hosmer-Lemeshow goodness-of-fit C chi-square and receiver operating characteristics (ROC) curve analyses.

RESULTS

A total of 871 patients were included in the analysis. The goodness-of-fit C chi-square test showed that both scores have a good performance in predicting survivors and nonsurvivors in CCU. Expanded SAPS II score has a sensitivity of 80% and a specificity of 91.8% with the cut-off value of 5.55, while APACHE II has a sensitivity of 75.9% and a specificity of 87.4% with the cut-off value of 16.5 in predicting mortality.

CONCLUSION

Expanded SAPS II and APACHE II scores have good ability to predict in-hospital mortality in CCU patients. Therefore, they can be used as a tool to predict short-term mortality in cardiovascular emergencies.

Cohort profile: the ESC EURObservational Research Programme Non-ST-segment elevation myocardial infraction (NSTEMI) Registry

AIMS

The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation.

METHODS AND RESULTS

Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin.

CONCLUSION

The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Predicting the Severity of Coronary Artery Disease: Can the Leukocyte Glucose Index be Used?

OBJECTIVE

To investigate the usability of leuko-glycemic index (LGI) at chronic coronary syndromes (CCS) class 1 for determining the extent and severity of coronary artery disease (CAD).

STUDY DESIGN

An observational study.

PLACE AND DURATION OF STUDY

Department of Cardiology, University of Pamukkale University Hospital, Turkey, between September 2021 and January 2022.

METHODOLOGY

One hundred and thirty-four patients, whose myocardial perfusion scintigraphy (MPS) was requested due to CCS class 1, and on whom a coronary angiogram (CAG) was performed due to evidence of ischemia, were analysed. Blood samples were taken from the patients during their hospitalisation before CAG. LGI was calculated as mg/dl.mm3 by multiplying both values and dividing by a thousand. The patients were analysed in two groups according to the critical stenosis and non-critical stenosis detected in the coronary arteries.

RESULTS

The LGI was recorded as 480 mg/dl.mm3 (407-603) vs. 572 mg/dl.mm3 (433-877), p=0.006, and the Gensini score (6 (3-10) vs 40 (23-60), p<0.001) was significantly higher in the critical CAD group. A significant relationship has detected the increase in LGI and the extensity and severity of CAD (Unadjusted; OR (95% CI); 1.003 (1.001 - 1.004) p=0.002, adjusted; OR (95% CI); 1.002 (1.001 - 1.004) p=0.004).

CONCLUSION

A high LGI was a predictor of CAD severity among CCS class 1 patients and was found to correlate with the Gensini score. The use of this simple and inexpensive index, together with other non-invasive tests before CAG, may provide some knowledge about the severity of CAD.

APACHE II score predicts in-hospital mortality more accurately than inflammatory indices in patients with acute coronary syndrome

Aim    This study evaluated the prognostic ability of the APACHE II score and compared it with inflammatory indices in patients with acute coronary syndrome (ACS).Material and Methods    A total of 525 patients with ACS were retrospectively enrolled in the study. APACHE II scores were calculated and C-reactive protein (CRP), neutrophil-lymphocyte ratio (NLR), and systemic immune-inflammatory index (SII) were recorded. The APACHE II score was compared with inflammatory indices for predicting in-hospital mortality.Results    Univariate logistic regression (LR) analysis showed that CRP, SII, NLR, ejection fraction, chronic kidney disease, gender, and APACHE II score were significant predictors of mortality. In multiple LR analysis, the APACHE II score was found to be a solitary, significant predictor of in-hospital mortality (OR: 1.201, 95 % CI: 1.122-1.285; p&lt;0.001). In the Receiver Operating Characteristics curve, using a cut-off point of 16.5, the APACHE II score predicted in-hospital mortality with 70.4 % sensitivity and 92.9 % specificity.Conclusion    The APACHE II score may be used as a predictor of in-hospital mortality better than inflammatory markers in ACS patients.

3D Evaluation of the Relationship between Different Vertical Growth Patterns and Cranial Base Angulations

Objectives This study aimed to compare cranial base angulations in subjects with high-angle, low-angle, and normal-angle vertical growth patterns using cone beam computed tomography (CBCT).

Design This study is a retrospective clinical research.

Settings This study was carried out at the Dentistry Faculty of Eskisehir Osmangazi University.

Participants According to skeletal vertical face growth patterns, 78 subjects (48 females and 30 males, average age: 13.19 ± 1.73 years) were divided equally into three groups: high angle, low angle, and normal angle groups.

Main Outcome Measures Cephalometric images were derived from CBCT, and patients were classified according to the SN-GoGn angle (sella-nasion, gonion gnathion angle). Sagittal, axial, and coronal cranial base angulations were measured in three-dimensional (3D) CBCT images. Data were analyzed using the Kolmogorov–Smirnov normality, Kruskal–Wallis, and Mann-Whitney U statistical tests.

Results There were statistically significant differences between the low-angle and high-angle groups according to sagittal cranial base angulation parameters (p = 0.01). Conversely, there were no statistically significant differences between vertical facial growth patterns according to coronal and axial cranial angle variables (p > 0.05).

Conclusion According to the study results, there were no effects of cranial base angulations in two planes (coronal and axial) on different vertical skeletal growth patterns. In the sagittal cranial base angulation parameter, the high-angle group showed greater angulation values than the low-angle group. CBCT may be helpful for evaluating, diagnosing, and predicting 3D cranial base differences.

The Relationship Between Mitral Annular Calcification, Metabolic Syndrome and Thromboembolic Risk

INTRODUCTION

Metabolic syndrome (MetS) is defined as an association between diabetes, hypertension, obesity and dyslipidemia and an increased risk of cardiovascular disease. Mitral annular calcification (MAC) is associated with several cardiovascular disorders, including coronary artery disease, atrial fibrillation (AF), heart failure, ischemic stroke and increased mortality. The CHA2DS2-VASc score is used to estimate thromboembolic risk in AF. However, the association among MAC, MetS and thromboembolic risk is unknown and was evaluated in the current study.

METHODS

The study group consisted of 94 patients with MAC and 86 patients with MetS. Patients were divided into two groups: those with and those without MAC.

RESULTS

Patients with MAC had a higher MetS rate (P<0.001). In patients with MAC, the CHA2DS2-VASc scores and the rate of cerebrovascular accident and AF were significantly higher compared to those without MAC (P<0.001, for both parameters). The results of the multivariate regression analysis showed that history of smoking, presence of MetS and high CHA2DS2-VASc scores were associated with the development of MAC. ROC curve analyses showed that CHA2DS2-VASc scores were significant predictors for MAC (C-statistic: 0.78; 95% CI: 0.706-0.855, P<0.001). Correlation analysis indicated that MAC was positively correlated with the presence of MetS and CHA2DS2-VASc score (P=0.001, r=0.264; P<0.001, r=0.490).

CONCLUSION

We have shown that CHA2DS2-VASc score and presence of MetS rates were significantly higher in patients with MAC compared without MAC. Presence of MAC was correlated with CHA2DS2-VASc score, presence of MetS, AF and left atrial diameter and negatively correlated with left ventricular ejection fraction.

Evaluation of the relationship between impacted canines and three-dimensional sella morphology

PURPOSE

The purpose of this study was to assess the three-dimensional morphometric features of the sella turcica using cone beam computed tomography (CBCT) in subjects with unilateral and bilateral maxillary impacted canines and normal controls.

METHODS

In this retrospective study, CBCT images captured with ultra-low dose protocol of 73 subjects (21 males, 52 females; mean age 20.01 ± 6.53 years) with unilateral or bilateral maxillary impacted canines (29 unilateral and 29 bilateral) and 15 controls were evaluated. Nineteen different measurements of the pituitary fossa were made on CBCT images. To evaluate the normality, the Kolmogorov-Smirnov test was used. The nonparametric statistical Kruskal-Wallis and Mann-Whitney U tests were applied to analyze the significant differences among and between the groups. Statistical significance was set at 5%.

RESULTS

No measurement differed significantly among the groups (all p > 0.05) other than the right sella length, which differed between the unilateral and bilateral test groups and the unilateral test group and controls (both p < 0.05). The bilateral test group and control group did not differ significantly, but both exhibited greater right sella length than did the unilateral test group (p > 0.05).

CONCLUSIONS

Other than the right sella length, there were no among-group differences in the mean pituitary fossa measurements of subjects with impacted unilateral and bilateral canines and normally erupted canines. The right sella length was lower in subjects with impacted unilateral canines than in those with bilateral impacted canines and normal controls.

The Relation Between Echocardiographic Epicardial Fat Thickness and CHA2DS2-VASc Score in Patients with Sinus Rhythm

Objective

To evaluate the predictive value of epicardial fat thickness (EFT) in CHA₂DS₂-VASc (congestive heart failure, hypertension, age ≥75 years, diabetes mellitus, previous stroke or transient ischemic attack, vascular disease, age 65-74 years, sex category) score risk groups.

Methods

A total of 158 consecutive patients (75 females, 83 males, mean age 70.8±6.3 years) admitted routinely for cardiologic control were divided into two groups according to their CHA₂DS₂-VASc scores (scores 0 and 1 were regarded as low risk, and score ≥2 as high risk). One hundred twenty-five of 158 patients had a high-risk score.

Results

Mean EFT was significantly higher in the high-risk group than in the low-risk group (4.34±0.62 vs. 5.37±1.0; P<0.001). EFT was positively correlated with CHA₂DS₂-VASc score (r=0.577, P<0.001). According to receiver operating characteristics (ROC) analysis, EFT value of 4.4 mm was found to be predictive of high risk in CHA₂DS₂-VASc score with 80% of sensitivity and 79% of specificity (C-statistic = 0.875, P<0.001, 95% confidence interval [CI] = 0.76-0.90). And according to multivariate logistic regression analysis, EFT was an independent predictor of high thromboembolic risk in terms of CHA₂DS₂-VASc score.

Conclusion

Our findings suggest that echocardiographic EFT measurement could provide additional information on assessing cardiovascular risks, such as thromboembolic events, and individuals with increased EFT should receive more attention to reduce unfavorable cardiovascular risk factors and the development of future cardiovascular events.

Three-dimensional evaluation of angular, linear, and resorption features of maxillary impacted canines on cone-beam computed tomography

OBJECTIVES

The aim of this study was to evaluate the localization, angulation, and resorption features of maxillary impacted canines on cone-beam computed tomography (CBCT).

METHODS

This retrospective study examined the CBCT scans of 140 maxillary impacted canines in 102 patients (43 males, 59 females; mean age: 16.25 ± 6.31 years). The following impacted canine-related parameters were analyzed on the CBCT images: impaction side; location; root resorption levels of adjacent teeth; occlusal plane and midline distances of impacted canines; and angulations of impacted canines to midline, lateral incisor, and occlusal plane.

RESULTS

Bilateral canine impaction was found in 38 subjects, and unilateral canine impaction was present in 64 subjects. Severe resorption was found in 14 canines. There were no significant differences between the occlusal plane and midline distances to the impacted canine cusp tip and root apex (p > 0.05). The midline angulation of right maxillary impacted canines was significantly higher than that of left maxillary impacted canines (p < 0.05), while the occlusal plane angulation of left maxillary impacted canines was significantly higher than that of right maxillary impacted canines (p < 0.05).

CONCLUSIONS

Maxillary canine impaction was more frequently seen in female subjects than in male subjects. Lateral incisors were more frequently affected than first premolars, and slight resorption was more frequently seen in adjacent teeth. CBCT assessment of maxillary impacted canines can provide accurate measurements of angular, linear, and resorption parameters.

Nebivolol versus Carvedilol or Metoprolol in Patients Presenting with Acute Myocardial Infarction Complicated by Left Ventricular Dysfunction

OBJECTIVE

The aim of this study was to evaluate the efficacy of nebivolol, carvedilol or metoprolol succinate on the outcome of patients presenting with acute myocardial infarction (AMI) complicated by left ventricular dysfunction.

SUBJECTS AND METHODS

Patients (n = 172, aged 28-87 years) with AMI and left ventricular ejection fraction ≤0.45 were randomized to the nebivolol (n = 55), carvedilol (n = 60) and metoprolol succinate (n = 57) groups. Baseline demographic and clinical characteristics and composite event rates of nonfatal MI, cardiovascular mortality, hospitalization due to unstable angina pectoris or heart failure, stroke or revascularization during the 12-month follow-up were compared among the groups using the x03C7;2 test, t test or log-rank test as appropriate.

RESULTS

Baseline demographic and clinical characteristics were similar in the three groups. The composite end point during follow-up was lower in the patients treated with nebivolol than those treated with metoprolol (14.5 vs. 31.5%; p = 0.03). However, event rates were similar between the patients treated with carvedilol and those treated with the metoprolol (20.3 vs. 31.5%, p > 0.05) and between the patients treated with nebivolol and carvedilol (14.5 vs. 20.3%, p > 0.05).

CONCLUSION

The patients treated with nebivolol experienced 12-month cardiovascular events at a lower rate than those treated with metoprolol succinate. However, event rates were similar between the carvedilol and the metoprolol succinate groups and between the nebivolol and the carvedilol groups.

Late perforation of anterior mitral leaflet after surgical resection of the subaortic membrane

A 54-year-old woman who underwent surgical resection of the subaortic membrane 10 years earlier presented with new onset dyspnea. Cardiovascular examination revealed 3-4/6 pansystolic murmur at the apex. She was found to have severe mitral regurgitation (MR) with transthoracic echocardiography; 2D and real-time-3D transesophageal echocardiography demonstrated severe MR through anterior mitral leaflet perforation with precise localization. The patient was treated with surgery in which the perforated segment was closed by direct suture technique and discharged on postoperative 5th day. <Learning objective: Late anterior mitral leaflet perforation after surgical or interventional procedures has rarely been reported. We present this case to emphasize the role of traumatic injury to weak endothelial surfaces such as a valve leaflet in the development of late leaflet perforation after surgical or interventional procedures.>.

The first case of levetiracetam-induced and tolvaptan-resistant hyponatremia

Hyponatremia is frequently seen in heart failure patients and has a high mortality rate. If not treated adequately, acute and chronic hyponatremia may worsen the prognosis of heart failure. Despite its high incidence in heart failure patients, other underlying conditions that possibly lead to the incidence of hyponatremia may be underestimated, thus making its treatment more difficult. In this case study, we describe a rare case of levetiracem-induced and tolvaptan-resistant hyponatremia.

Increased plasma monocyte chemoattractant protein-1 levels in patients with isolated low high-density lipoprotein cholesterol

BACKGROUND

High-density lipoprotein cholesterol (HDL-C) inhibits inflammation associated with the development of atherosclerotic plaques. Monocyte chemoattractant protein-1 (MCP-1) contributes to the pathogenesis of atherosclerosis. The aim of this study was to evaluate the relationship between plasma MCP-1 levels and low HDL-C levels in patients without cardiovascular disease (CVD).

METHODS

This study included 55 patients with low HDL-C (≤ 35 mg/dL) and 33 age- and sex-matched control subjects with normal HDL-C (˃ 35 mg/dL). In addition to MCP-1 levels, laboratory parameters associated with inflammation such as neutrophil-lymphocyte ratio (NLR), uric acid and high sensitivity C-reactive protein (hs-CRP) were also evaluated.

RESULTS

HDL-C levels was significantly lower in study group compared to that of the control group (p < 0.001). MCP-1 were prominently higher in the low HDL-C group compared with those of the control group (p < 0.01). NLR, uric acid and hs-CRP levels were also higher in patients with low HDL-C than controls.

CONCLUSION

These findings suggest that elevated plasma MCP-1 levels and inflammation status might be associated with the increased cardiovascular risk in patients with low HDL-C.

The effect of intravenous magnesium sulfate infusion on sensory spinal block and postoperative pain score in abdominal hysterectomy

AIM

The aim of this study was to investigate the effect of i.v. infusion of magnesium sulphate during spinal anesthesia on duration of spinal block and postoperative pain.

METHODS

Forty ASA physical status I and status II, aged between 18 and 65, female patients undergoing abdominal hysterectomy under spinal anesthesia were enrolled in this study. Patients in the magnesium group (Group M, n = 20) received magnesium sulphate 65 mg kg(-1) infusion in 250 mL 5% dextrose at 3.5 mL/min rate, and control group (Group C, n = 20) received at the same volume of saline during operation in a double-blind randomized manner. Duration of sensory and motor block, systolic, diastolic, and mean arterial blood pressures, heart rates, pain scores (VAS values), and side effects were recorded for each patient. Blood and CSF samples were taken for analysis of magnesium concentrations.

RESULTS

Regression of sensorial block was longer in Group M when compared with that in Group C (175 ± 39 versus 136 ± 32 min) (P < 0.01). The VAS scores were lower in Group M than those in Group C at the 2 time points postoperatively (P < 0.01).

CONCLUSION

65 mg kg(-1) of magnesium sulphate i.v. infusion under spinal anesthesia prolongs spinal sensorial block duration and decreases pain VAS scores without complication in patients undergoing abdominal hysterectomy.

Low High-Density Lipoprotein Cholesterol Is Characterized by Elevated Oxidative Stress

High-density lipoprotein cholesterol (HDL-C) is an independent risk factor for premature atherosclerosis and cardiovascular disease. Plasma HDL exerts potent antioxidant activity. We evaluated parameters associated with oxidative stress in participants with low HDL-C. This study included 32 patients with low HDL-C (≤35 mg/dL) and 33 age- and sex-matched control patients with normal HDL-C (>35 mg/dL). We evaluated clinical and laboratory parameters that are associated with oxidative stress. The oxidative stress index (OSI) levels were significantly higher in the low HDL-C group (3.32 [0.01-13.3] vs 0.74 [0.17-3.55] AU; P < .01) and negatively correlated with HDL-C levels. We suggest that change in OSI and uric acid levels in the study group might indicate increased oxidative status in patients with low HDL-C. This may be associated with increased cardiovascular risk.

[Cardiac device related infective endocarditis; analysis of 15 cases]

OBJECTIVES

We aimed to investigate the demographic and clinical characteristics, echocardiographic and microbiologic features, and outcomes of patients with permanent pacemaker (PM) and implantable cardioverter-defibrillator (ICD) endocarditis in this study.

STUDY DESIGN

The study population consisted of 15 patients with permanent PM and ICD endocarditis. Data on demographics, medications, clinical procedures, microbiology, echocardiography, surgery, and outcome were collected.

RESULTS

The mean age of the patients was 57 ± 16. Seven patients (47%) were female. Of the 15 permanent PM and ICD endocarditis patients, 5 died during hospital follow-up (33%). Four patients (27%) experienced a pulmonary embolism. Culture-negative endocarditis was seen in 5 cases (33%). Staphylococci were the most common causative organisms (60%). Three patients had undergone surgical treatment (20%).

CONCLUSION

Cardiac device-related endocarditis remain a rare but potentially fatal complication of device implantation.

Mean esophageal radiation dose is predictive of the grade of acute esophagitis in lung cancer patients treated with concurrent radiotherapy and chemotherapy

The intention of this research was to define the predictive factors for acute esophagitis (AE) in lung cancer patients treated with concurrent chemotherapy and three-dimensional conformal radiotherapy. The data for 72 lung cancer patients treated with concurrent chemoradiotherapy between 2008 and 2010 were prospectively evaluated. Mean lung dose, mean dose of esophagus, volume of esophagus irradiated and percentage of esophagus volume treated were analysed according to esophagitis grades. The mean esophageal dose was associated with an increased risk of esophageal toxicity (Kruskal-Wallis test, P < 0.001). However, the mean lung dose and the volume of esophagus irradiated were not associated with an increased risk of esophageal toxicity (Kruskal-Wallis test, P = 0.50 and P = 0.41, respectively). The mean radiation dose received by the esophagus was found to be highly correlated with the duration of Grade 2 esophagitis (Spearman test, r = 0.82, P < 0.001). The mean dose of esophagus ≥28 Gy showed statistical significance with respect to AE Grade 2 or worse (receiver operating characteristic curve analysis, 95% CI, 0.929-1.014). In conclusion, the mean esophageal dose was significantly associated with a risk of esophageal toxicity in patients with lung cancer treated with concurrent radiotherapy and chemotherapy.

Socio-demographic and clinical characteristics of individuals with diagnoses of eating disorder in a university hospital in Istanbul

OBJECTIVE

This paper reports the first-ever description of a clinical eating disorder population from Turkey. The aim of this study was to examine the socio-demographic and clinical characteristics of individuals with diagnosis of eating disorders (IDED) referred to a university psychiatry clinic in Istanbul between 2003 and 2009.

METHOD

The diagnoses and subtype of 111 IDEDs, the referral type to the hospital, setting of treatment, and state of involuntary hospitalization were evaluated by interview and semi-structured questionnaire.

RESULTS

The clinical sample included 64 individuals with anorexia nervosa (AN), 38 with bulimia nervosa (BN), and 9 with eating disorder not otherwise specified (EDNOS), including only one male. Younger individuals and those with a lower BMI were significantly more likely to be family referred and hospitalized involuntarily.

DISCUSSION

The overall socio-demographic features of the sample are generally consistent with data collected in other communities. However, aspects of the clinical features, referral types of eating disorders and subtypes exhibit some characteristics peculiar to our sample.

Comparison of Entropy and Bispectral Index during Propofol and Fentanyl Sedation in Monitored Anaesthesia Care

Comparison of entropy (state entropy [SE] and response entropy [RE]) with the bispectral index (BIS) during propofol sedation in monitored anaesthesia care (MAC) was carried out in patients undergoing hand surgery. Thirty candidates for elective hand surgery were pre-medicated with midazolam 0.06 mg/kg and atropine 0.01 mg/kg. Sedation was induced with intravenous propofol and fentanyl was also administered. The Modified Observer's Assessment of Alertness/Sedation Scale (MOAA/S) was used to determine sedation level and pain was maintained at < 4 on a 0-10 verbal rating scale. The BIS, entropy, MOAA/S and pain values were recorded before initiation of sedation (control), during initiation of sedation, during surgery, and for 30 min after the end of surgery and anaesthesia. On initiation of sedation, entropy decreased more rapidly than BIS. At 10 min after initiation of sedation, the mean ± SD values for MOAA/S, BIS, RE and SE were 3.00 ± 0.36, 85.45 ± 0.15, 74.00 ± 0.60 and 72.02 ± 0.12, respectively. During recovery, BIS and RE and SE increased in parallel with MOAA/S. It is concluded that entropy monitoring is as reliable as BIS monitoring in MAC.
