Relationship between non-alcoholic fatty liver disease and coronary heart disease

Non-alcoholic fatty liver disease (NAFLD) is the leading cause of chronic liver disease and considered a liver manifestation of metabolic syndrome. It is in close relationship with insulin resistance, obesity, diabetes mellitus, all of which increase risk of cardiovascular disease (CVD). Besides, many studies point out that NAFLD independently contributes to the development of atherosclerosis and CHD. On the other hand, CVDs are the leading cause of death in NAFLD patients. Many pathophysiological changes and molecular mechanisms play an important role in NAFLD for CVD formation. Atherosclerosis is common in NAFLD, which also mainly contributes to the CVD formation and CHD. Many studies linking atherosclerotic CHD and NAFLD are present in the literature. Subclinical CHD, mainly detected by coronary computed tomography views, have been detected more common in NAFLD patients. Presence of NAFLD has been found to be more common in patients with severe CHD and in stable CHD, NAFLD has been found to be associated with more diffuse disease. In acute coronary syndromes, especially in acute myocardial infarction, patients with NAFLD have been found to have poor prognosis when compared with NAFLD free patients. In this review, our aim is to evaluate the relationship between NAFLD and CHD in detail and go over the pathophysiological mechanisms underlying this relationship.     

Drug dependence and its risk factors in emergency department patients: A retrospective cross-sectional study

Objective: To determine the characteristics and risk factors of drug dependence among patients who were administered drugs with addictive potential (DAP) in an emergency department (ED).Methods: This retrospective cross-sectional study included patients who were administered DAP 3 or more times in the emergency room between September 1, 2019 and March 1, 2020. The demographic and baseline information were recorded. All the prescibed DAP, the reasons to use these drugs, secondary drug dependence, the department where DAP were first prescribed, types of doctors who preferred to prescribed DAP, and the risk factors for the development of drug dependence were determined. Results: A total of 3000 patients were screened from medical records, and among them, 80 patients developed drug dependence. Drug dependence only developed for tramadol (n=57, 71.3％), diazepam (n=11, 13.8％), and biperiden (n=12, 15.0％). Tramadol was the most frequently prescribed drug (n=57, 71.3％). The most common reason for drug dependence was psychiatric disorders (n=29, 36.3％). Drug dependence developed in renal colic patients due to the administration of tramadol (n=7, 100％). On the contrary, dependence to biperiden were mainly developed in patients with psychiatric complaints (n=12, 41.4％). The rate of secondary drug dependence was 15％ (n=12). Of the Biperiden users, 41.7％ developed secondary drug dependence on diazepam. Most DAP were first prescribed in the ED (n=52, 65％), and the specialist preferred to prescribe DAP (n=43, 53.8％). For the development of dependence, the presence of renal colic (OR: 3.387, 95％ confidence interval (CI): 1.473-7.788, P=0.004) and low back pain (OR: 5.778, 95％ CI: 2.779-12.014, P<0.001) were the risk factors. Conclusions: Most DAP were first prescribed in the ED compared to other departments, and specialist are preferred to use DAP. Tramadol is the most commonly used drugs caused drug dependence. Psychiatric disorder patients are easier to develope drug dependence. Furthermore, renal colic and low back pain patients needs more attention to avert drug dependence.     

The relationship between chronic kidney disease and SYNTAX score

Chronic kidney disease (CKD) is associated with increased risk of cardiovascular disease and death. We evaluated the association between CKD and severity of coronary artery stenosis by calculating SYNTAX Score in patients with left main coronary artery and/or 3-vessel coronary artery disease. Coronary angiograms of 217 patients were assessed. Chronic kidney disease was staged using the estimated glomerular filtration rate (eGFR, mL/min per 1.73 m(2)) prior to coronary angiography. Patients were divided into 5 groups according to the National Kidney Foundation Kidney Disease Outcome Quality Initiative (NKF KDOQI) Clinical Practice Guidelines (14). Patients with eGFR >90 mL/min per 1.73 m(2) (group 1), patients with eGFR 60 to 89 mL/min per 1.73 m(2) (group 2), patients with eGFR 30 to 59 mL/min per 1.73 m(2) (group 3), patients with eGFR >15 to < 30 per 1.73 m(2) and dialysis patients with eGFR < 15 per 1.73 m(2) were combined as group 4. The risk of significant lesion complexity increased progressively with decreasing kidney function (P = .001). Estimated glomerular filtration rate was a strong predictor of higher SYNTAX Score.     

Cetuximab plus FOLFOX6 or FOLFIRI in metastatic colorectal cancer: CECOG trial

AIM: To investigate efficacy and safety of cetuximab combined with two chemotherapy regimens in patients with unresectable metastatic colorectal cancer (mCRC). METHODS: Randomized patients received cetuximab with 5-fluorouracil (5-FU), folinic acid (FA) and oxaliplatin (FOLFOX) 6 (arm A, n = 74) or 5-FU, FA and irinotecan (FOLFIRI) (arm B, n = 77). KRAS mutation status was determined retrospectively in a subset of tumors (n = 117). RESULTS: No significant difference was found between treatment arms A and B ...     

Inflammatory Pseudotumor of the Spleen: Report of a Case

We report the case of an inflammatory pseudotumor of the spleen in an asymptomatic 55-year-old woman, whose lesion was accidentally found and clinically misdiagnosed to be lymphoma. An inflammatory pseudotumor of the spleen was histopathologically diagnosed following a splenectomy. This lesion is a benign, reactive, and inflammatory process and its etiopathogenesis still remains elusive. The preoperative diagnosis is difficult and the optimal management of the asymptomastic patient with the disease is unclear. This entity should be kept in mind in the differential diagnosis of splenic space-occupying lesions.     

Hybrid Repair of an Acute Type B Dissection with Subclavian‐to‐Subclavian Bypass and Stent‐Grafting

Abstract Hybrid repair of an acute type B aortic dissection with endovascular stenting and aortic arch debranching is an acceptable treatment in complicated type B dissection. We present the case of a 71‐year‐old man presenting with acute type B aortic dissection and concomitant aneurysm of the distal aortic arch, who underwent an uneventful hybrid procedure, which involved subclavian‐to‐subclavian bypass before endovascular stent‐graft placement to the aortic arch.

Early Myocardial Functional Alterations in Patients with Obstructive Sleep Apnea Syndrome

Background: There is limited information regarding myocardial alterations in patients with obstructive sleep apnea syndrome (OSAS) in the absence of pulmonary and cardiac comorbidity. In this study, we aimed to evaluate potential myocardial alterations of these patients and investigate the possible effects of OSAS-related pathological variations on left and right ventricular functions. Methods: We studied 107 consecutive patients who were referred to our sleep laboratory for clinically suspected OSAS and 30 controls without any history or symptoms of sleep-related disorders. Severity of OSAS was quantified by polysomnography. Patients with apnea–hypopnea index (AHI) < 5 were included in the OSAS (−) group (Group 1, n = 22). Subjects with AHI ≥ 5 were considered as OSAS and classified according to their AHI as mild-to-moderate (AHI ≥ 5 and AHI < 30) (Group 2, n = 45) and severe (AHI ≥ 30) OSAS groups (Group 3, n = 40). Conventional M-mode, 2D, and Doppler mitral inflow parameters, tissue Doppler velocities, myocardial peak systolic strain, and strain rate values of various segments were measured and compared between groups. Results: Patients with OSAS displayed impairment of left ventricular diastolic function compared with controls. There were no significant differences between groups regarding parameters reflecting left ventricular systolic function. Myocardial strain analysis demonstrated significant decrement regarding apical right ventricular longitudinal peak systolic strain and strain rate values between groups in relation to the severity of OSAS. Conclusions: Patients with OSAS display a regional pattern of right ventricular dysfunction correlated with the severity of disease.
