Knowledge, Attitudes, and Perception towards COVID-19 Vaccination among the Adult Population: A Cross-Sectional Study in Turkey.

Background: The coronavirus disease 2019 (COVID-19) pandemic continues to wreak havoc on lives and ravage the world. Several vaccines have been approved for use against COVID-19; however, there may be hesitancy and negative perceptions towards vaccination, which may reduce the willingness to be vaccinated. Further, studies assessing the current perception toward COVID-19 vaccination are scarce.

Use of GRP Pipe Waste Powder as a Filler Replacement in Hot-Mix Asphalt.

There is an increasing global trend to find sustainable, environmentally friendly and cost-effective materials as an alternative to limited natural raw materials. Similarly, the use of waste materials has been gaining popularity in the production of hot-mix asphalt (HMA). In this study, the sustainable use of glass-fiber-reinforced polyester (GRP) pipe waste powder (GRP-WP), gathered from the cutting and milling process of GRP pipe production, utilizing it in asphalt mixes as a filler, is evaluated based on lab testing to find out: (i) if it produces similar or better performance compared to the most conventionally available filler material (limestone) and, (ii) if so, what would be the optimum GRP-WP filler content to be used in asphalt mixes.

[Laboratory signs of activation of the hemostasis system in patients with coronary heart disease, who had coronary artery bypass surgery.].

The hypercoagulable state is a risk factor for shunt thrombosis in patients who had coronary artery bypass surgery. That is why the study of factors and operative intervention which can lead to hypercoagulable states are extremely valuable and vital issues. 85 patients who had coronary artery bypass surgery were examined.

[Pulmonary fibrosis as the first manifestation of scleroderma systematica overlap syndrome].

The paper describes a clinical case of a female patient with signs of visceral scleroderma systematica and rheumatoid arthritis (RA). Interstitial pulmonary fibrosis was the first manifestation of overlap syndrome. The articular and cutaneous of the syndrome were moderate and cast doubts upon whether the systemic rheumatic disease was present.

[A case of multifocal fibrosis].

We report a case of multifocal fibrosis extending retroperitoneally (Ormond's syndrome) with urinary tract obstruction and bilateral ureterohydronephrosis that resulted in chronic renal insufficiency. The development of mediastinal and pericardial fibrosis was accompanied by clinical symptoms of exudative and constrictive pericarditis. Fibrosis of cardiac conducting system was associated with compromised sinus node and intraventricular blockade.
