Evaluation of beta-blockers on left ventricular dyssynchrony and reverse remodeling in idiopathic dilated cardiomyopathy: A randomized trial of carvedilol and metoprolol

Background: The effect of b-blockage on cardiac dyssynchrony in idiopathic dilated cardio­myopathy (IDC) is unknown. This study evaluated the impact of carvedilol and metoprolol succinate on left ventricular (LV) dyssynchrony and reverse remodeling in IDC. Methods: In this small, prospective, double-blind study, we randomly assigned 81 IDC pa­tients to receive carvedilol or metoprolol succinate. Echocardiographic measurements (dyssyn­chrony, LV volumes and ejection fraction [EF]) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were obtained at baseline and at first and sixth month of therapy. Results: A total of 74 (91%) patients completed all investigations at sixth month (38 and 36 taking carvedilol and metoprolol succinate, respectively). In the carvedilol group, reduction in LV end diastolic volume (D LVEDV at 6 months, 50 ± 15 mL to 40 ± 17 mL, p = 0.03) and increase in LVEF (D LVEF, 7 ± 2% to 5 ± 3%, p = 0.02) was higher compared to the meto­prolol group. Also improvement in inter-ventricular dyssynchrony achieved with carvedilol was higher than metoprolol (D interventricular delay at 6 months, 11 ± 8 ms to 6 ± 7 ms, p = 0.03). However, improvement in intraventricular dyssynchrony was similar in the two groups (D intraventricular delay, 9 ± 7 ms to 9 ± 6 ms, p = 0.91). Improvements in LV mechanical dyssynchrony and reverse remodeling achieved with both drugs were accompanied by reduction in NT-proBNP levels in both carvedilol and metoprolol groups (1614 ± 685 pg/mL to 654 ± ± 488 pg/mL and 1686 ± 730 pg/mL to 583 ± 396 pg/mL, respectively, p < 0.001 for both). Conclusions: Although reduction in LVEDV and increase in LVEF was higher with carvedilol, improvement in intraventricular dyssynchrony was similar in carvedilol and metoprolol groups.

Amyloid Goiter Associated with Amyloidosis Secondary to Rheumatoid Arthritis

Amyloidosis refers to a variety of conditions in which amyloid proteins are abnormally deposited in organs and/or tissues. The most common forms of systemic amyloidosis are primary amyloidosis (PA) of light chains and secondary amyloidosis (SA) caused by chronic inflammatory diseases such as rheumatoid arthritis (RA). Although involvement of the thyroid gland by amyloid is a relatively common phenomenon, clinically significant enlargement of the thyroid owing to amyloid deposition is a rare occurrence. In SA, the deposition of amyloid associated (AA) protein is associated with atrophy of thyroid follicles. The clinical picture of these patients is characterized by rapid, painless thyroid gland enlargement which may be associated with dysphagia, dyspnea, or hoarseness. Thyroid function is not impaired in most cases. Although amyloid goitre secondary to systemic amyloidosis due to chronic inflammatory diseases is relatively common, specifically related to RA is much more uncommon one and it is reported less in the literature. In this report, A 52-old-year female patient with amyloid goiter associated with amyloidosis secondary to rheumatoid arthritis is presented

Relationship between psychosocial status, diabetes mellitus, and left ventricular systolic function in patients with stable multivessel coronary artery disease

Background: Negative emotional conditions contribute to the development of coronary artery disease (CAD). Depression and anxiety are prognostic factors in patients with CAD. The aim of our study was to investigate the association between emotional conditions and left ventricular (LV) systolic functions in CAD. Methods: 168 patients (102 men, 66 women, mean age 66.3 &#177; 9.9 years) with stable angina and multivessel disease (MVD) were included in the study. According to the LV ejection fraction (LVEF) in echocardiography, patients were divided into two groups, the preserved group (LVEF > 50%), and the impaired group (LVEF < 50%). The preserved group consisted of 94 patients and the impaired group consisted of 74 patients. Emotional status was evaluated using the Hamilton Depression (HAM-D), Hamilton Anxiety (HAM-A), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI) scores. Results: The prevalence of diabetes mellitus (DM) was significantly higher in the impaired group than in the preserved group (29.8% vs 56.8%, p < 0.01). The HAM-D, HAM-A, BAI and BDI scores were higher in the impaired group compared to the preserved group (HAM-D: 12.1 &#177; 3.3 vs 14.5 &#177; 2.3, p = 0.03; HAM-A: 12.7 &#177; 3.4 vs 14.3 &#177; 2.2, p = 0.01; BAI: 18.6 &#177; &#177; 6.4 vs 22.1 &#177; 6.6, p = 0.01 and BDI: 13.9 &#177; 2.5 vs 17.2 &#177; 2.0, p = 0.002, respectively). In multivariate analysis, BDI scores (odds ratio [OR]: 2.197, < 95% confidence interval [CI] 1.101&#8211;4.387; p = 0.026), HAM-A scores (OR: 1.912, < 95% Cl 1.092&#8211;2.974; p = 0.041) and DM (OR: 2.610, < 95% Cl 1.313&#8211;5.183; p = 0.006) were important risk factors for LV dysfunction in stable patients with MVD. Conclusions: This study demonstrated that emotional status and DM are factors associated with impaired LV systolic function in patients with stable CAD

Predictive value of admission red cell distribution width-platelet ratio for no-reflow phenomenon in acute ST segment elevation myocardial infarction undergoing primary percutaneous coronary intervention

Background: The red cell distribution width–platelet ratio (RPR), a novel inflammatory marker is currently used to predict inflammation in chronic diseases. It may be associated with adverse outcomes among artery disease but its prognostic value in ST-segment elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI) has not been fully investigated. There is no data regarding the association between RPR and in-hospital major adverse cardiovascular events (MACEs). This study evaluated the relations between pre-procedural RPR and the in-hospital and long-term outcomes in STEMI patients undergoing primary PCI. Methods: This study included 580 STEMI patients (77% men, mean age: 59 ± 12 years). The patients were divided into two groups according to thrombolysis in myocardial infarction (TIMI) flow grades after primary PCI. No-reflow was defined as a post-PCI TIMI flow grade of 0, 1 or 2 (group 1). Angiographic success was defined as TIMI flow grade 3 (group 2). Results: Whole blood cell count, neutrophil and lymphocyte percentages, red cell distribution width, platecrit, neutrophil–lymphocyte ratio (NLR) and RPR values were higher among patients with no-reflow. On multivariate analysis, pain to balloon time, multivessel disease, TIMI thrombus grade, tirofiban, aspirin, previous coronary artery disease, NLR, platecrit and RPR remained independent predictors of no-reflow after primary PCI. Patients in no-reflow group tended to be higher percent in-hospital MACE, including nonfatal myocardial infarction and cardiovascular mortality compared to the reflow patients. Conclusions: Admission NLR, platecrit and RPR are independent correlates of no-reflow and in-hospital MACEs among patients with STEMI undergoing primary PCI.

Cost-effectiveness analysis of left atrial appendage occlusion compared with pharmacological strategies for stroke prevention in atrial fibrillation

Background Transcatheter left atrial appendage occlusion (LAAO) is a promising therapy for stroke prophylaxis in non-valvular atrial fibrillation (NVAF) but its cost-effectiveness remains understudied. This study evaluated the cost- effectiveness of LAAO for stroke prophylaxis in NVAF. Methods A Markov decision analytic model was used to compare the cost-effectiveness of LAAO with 7 pharmacological strategies: aspirin alone, clopidogrel plus aspirin, warfarin, dabigatran 110 mg, dabigatran 150 mg, apixaban, and rivaroxaban. Outcome measures included quality-adjusted life years (QALYs), lifetime costs and incremental cost-effectiveness ratios (ICERs). Base-case data were derived from ACTIVE, RE-LY, ARISTOTLE, ROCKET-AF, PROTECT-AF and PREVAIL trials. One- way sensitivity analysis varied by CHADS2 score, HAS-BLED score, time horizons, and LAAO costs; and probabilistic sensitivity analysis using 10,000 Monte Carlo simulations was conducted to assess parameter uncertainty. Results LAAO was considered cost-effective compared with aspirin, clopidogrel plus aspirin, and warfarin, with ICER of US$5,115,$2,447, and $6,298 per QALY gained, respectively. LAAO was dominant (i.e. less costly but more effective) compared to other strategies. Sensitivity analysis demonstrated favorable ICERs of LAAO against other strategies in varied CHADS2 score, HAS-BLED score, time horizons (5 to 15 years) and LAAO costs. LAAO was cost-effective in 86.24$50,000/QALY. Conclusions Transcatheter LAAO is cost-effective for prevention of stroke in NVAF compared with 7 pharmacological strategies. Condensed abstract The transcatheter left atrial appendage occlusion (LAAO) is considered cost-effective against the standard 7 oral pharmacological strategies including acetylsalicylic acid (ASA) alone, clopidogrel plus ASA, warfarin, dabigatran 110 mg, dabigatran 150 mg, apixaban, and rivaroxaban for stroke prophylaxis in non-valvular atrial fibrillation management

Epidemiology of pemphigus in Turkey: One-year prospective study of 220 cases

Pemphigus is a group of rare and life-threatening autoimmune blistering diseases of the skin and mucous membranes. Although they occur worldwide, their incidence shows wide geographical variation, and prospective data on the epidemiology of pemphigus are very limited. Objective of this work is to evaluate the incidence and epidemiological and clinical features of patients with pemphigus in Turkey. All patients newly diagnosed with pemphigus between June 2013 and June 2014 were prospectively enrolled in 33 dermatology departments in 20 different provinces from all seven regions of Turkey. Disease parameters including demography and clinical findings were recorded. A total of 220 patients were diagnosed with pemphigus during the 1-year period, with an annual incidence of 4.7 per million people in Turkey. Patients were predominantly women, with a male to female ratio of 1:1.41. The mean age at onset was 48.9 years. Pemphigus vulgaris (PV) was the commonest clinical subtype (n=192; 87.3%), followed by pemphigus foliaceus (n=21; 9.6%). The most common clinical subtype of PV was the mucocutaneous type (n=83; 43.2%). The mean Pemphigus Disease Area Index was 28.14±22.21 (mean ± Standard Deviation).  The incidence rate of pemphigus in Turkey is similar to the countries of South-East Europe, higher than those reported for the Central and Northern European countries and lower than the countries around the Mediterranean Sea and Iran. Pemphigus is more frequent in middle-aged people and is more common in women. The most frequent subtype was PV, with a 9-fold higher incidence than pemphigus foliaceus.   </p

Evaluation of nutritional status in pediatric intensive care unit patients: the results of a multicenter, prospective study in Turkey

IntroductionMalnutrition is defined as a pathological condition arising from deficient or imbalanced intake of nutritional elements. Factors such as increasing metabolic demands during the disease course in the hospitalized patients and inadequate calorie intake increase the risk of malnutrition. The aim of the present study is to evaluate nutritional status of patients admitted to pediatric intensive care units (PICU) in Turkey, examine the effect of nutrition on the treatment process and draw attention to the need for regulating nutritional support of patients while continuing existing therapies.Material and MethodIn this prospective multicenter study, the data was collected over a period of one month from PICUs participating in the PICU Nutrition Study Group in Turkey. Anthropometric data of the patients, calorie intake, 90-day mortality, need for mechanical ventilation, length of hospital stay and length of stay in intensive care unit were recorded and the relationship between these parameters was examined.ResultsOf the 614 patients included in the study, malnutrition was detected in 45.4% of the patients. Enteral feeding was initiated in 40.6% (n = 249) of the patients at day one upon admission to the intensive care unit. In the first 48 h, 86.82% (n = 533) of the patients achieved the target calorie intake, and 81.65% (n = 307) of the 376 patients remaining in the intensive care unit achieved the target calorie intake at the end of one week. The risk of mortality decreased with increasing upper mid-arm circumference and triceps skin fold thickness Z-score (OR = 0.871/0.894; p = 0.027/0.024). The risk of mortality was 2.723 times higher in patients who did not achieve the target calorie intake at first 48 h (p = 0.006) and the risk was 3.829 times higher in patients who did not achieve the target calorie intake at the end of one week (p = 0.001). The risk of mortality decreased with increasing triceps skin fold thickness Z-score (OR = 0.894; p = 0.024).ConclusionTimely and appropriate nutritional support in critically ill patients favorably affects the clinical course. The results of the present study suggest that mortality rate is higher in patients who fail to achieve the target calorie intake at first 48 h and day seven of admission to the intensive care unit. The risk of mortality decreases with increasing triceps skin fold thickness Z-score

Use of GnRH Agonist (Desloreline) in Combination with PGF(2 alpha) on the Termination of Pregnancy in Bitches

Ten bitches whose sexual cycle periods were determined with vaginal cytology to be mated at appropriate time were used in this study. Desloreline implant (Suprelorin (R)) was inserted under the dorsal skin of bitches that were determined to be pregnant using ultrasonography 20 days after the first day of mating. Ten days after the implant insertion, single dose PGF(2 alpha) (cloprostenol, 20 mu g/kg, IM) was administered. The pregnancy was terminated on all bitches that received this procedure. It was determined that the level of progesterone decreased from an average of 28.87 +/- 11.86 ng/ml on the day of implant insertion (day 20-21 of pregnancy) to 0.43 +/- 0.31 ng/ml when the abortion was completed. It was observed that after the implant insertion, the abortion was completed in an average of 3.9 +/- 0.7 days following PGF(2 alpha) administration. It has been observed that abortions was completed in an average of 2,3 +/- 0.48 days after the first vaginal discharge was seen. In conclusion, it was determined that Desloreline, a GnRH agonist, successfully could terminate pregnancy when it is combined with a single dose of PGF(2 alpha) administration in bitches
