Assessing the sustainability index of part-time and full-time hazelnut farms in Giresun and Ordu Province, Turkey.

The study's primary purposes were to assess the sustainability of hazelnut farms and explore the effects of part-time and full-time farming types on sustainability in hazelnut production in the Giresun and Ordu Province of Turkey. One hundred fifty-two hazelnut farms were selected using the stratified sampling method, and data were collected by using face-to-face questionnaires. Several steps were taken, including using factor analysis after standardizing the variables to determine their weights to calculate the composite hazelnut farms' sustainability index.

Evaluating eco-efficiency and optimal levels of fertilizer use based on the social cost and social benefits in tea production.

The extensive use of synthetic fertilizers is increasing continuously to meet the growing demand of food worldwide. This excessive use of fertilizer not only pose a threat to the sustainability but also cause negative externalities in form of hidden social cost to the society The present study estimated social costs and benefits associated with excessive use of chemical fertilizers at tea farms and also evaluated eco-efficiency of tea growers in Rize Province of Turkey. Data envelopment analysis (DEA) was used in this study.

Cardiac surgery and hematologic malignancies: a retrospective single-center analysis of 56 consecutive patients.

Objective: Patients with a history of hematologic malignancies (HMs) are considered high-risk candidates for cardiac surgery. Increased perioperative rates of infections, thrombo-embolic complications, and bleeding disorders are reported. However, low patient numbers and lack of control groups limit all published studies.

Emergency computed tomography for aortic valve vegetation mimicking disruption.

A 47-year-old man presented with symptoms typical of infective endocarditis and history of streptococcal meningitis 8 months previously. Echocardiography showed a large aortic valve vegetation that was interpreted as disruption of the noncoronary cusp. This was ruled out by 64-slice cardiac computed tomography.

Heartmate II implantation with right coronary bypass grafting in ischemic cardiomyopathy with "fixed" pulmonary hypertension: treatment strategy to protect right ventricular function.

A 49-year-old male patient suffering from end-stage ischemic cardiomyopathy with a left ventricular ejection fraction below 15% was presented to redo coronary artery bypass grafting (CABG). Coronary angiogram demonstrated an occluded left anterior descending artery and occluded right coronary artery, perfused retrogradely from the circumflex artery. Since positron emission tomography did not demonstrate viable left ventricular myocardium except for the basis of the left ventricle, CABG was considered futile.

The innominate vein as alternative venous access for complicated implantable cardioverter defibrillator revisions.

Background: Venous complications of implantable cardioverter defibrillator (ICD) systems may cause significant problems when the need for system revision or upgrades arises. Such revisions require venous access close to the site of the previous ICD implantation. The internal and external jugular vein have disadvantages due to a long subcutaneous course crossing the clavicle and problems with lead extraction if infection occurs.
