COVID-19: vaccination vs. hospitalization.

Objective: Vaccination is the most efficient way to control the coronavirus disease 2019 (COVID-19) pandemic, but vaccination rates remain below the target level in most countries. This multicenter study aimed to evaluate the vaccination status of hospitalized patients and compare two different booster vaccine protocols.

Setting: Inoculation in Turkey began in mid-January 2021.

COVID-19 Pandemic and the Global Perspective of Turkish Thoracic Society.

It has been more than 3 months now since the first case of COVID-19 was reported in Turkey. Globally, the number of confirmed cases and deaths reached 9,653,048 and 491,128 respectively, as reported by 216 countries by June 27, 2020. Turkey had 1,396 new cases, 194,511 total cases, and 5,065 deaths by the same date.

Comparative evaluation of biogas production from dairy manure and co-digestion with maize silage by CSTR and new anaerobic hybrid reactor.

This study aimed to investigate potential methane production through anaerobic digestion of dairy manure and co-digestion with maize silage. Two different anaerobic reactor configurations (single-stage continuously stirred tank reactor [CSTR] and hybrid anaerobic digester) were used and biogas production performances for each reactor were compared. The HR was planned to enable phase separation in order to improve process stability and biogas production under higher total solids loadings (≥4%).

[False positive 18F-FDG PET/CT findings mimicking malignant disease in patients with pneumoconiosis (due to three case reports)].

Besides the risk of developing pneumoconiosis and chronic obstructive pulmonary disease, potential lung cancer risk may also increase due to exposure to silica and other carcinogens. Patients with hemoptysis symptom referred to our clinic depending on different forms of mass images in their thorax computerize tomography (CT) scan with the suspicion of coal-worker pneumoconiosis and lung cancer were hospitalized for investigation and treatment. The results of routine tests, sputum acid-fast bacilli and sputum cytology were evaluated as normal.

Polymorphisms in the vitamin D receptor gene and risk of lung cancer.

Background: Differences between the individual variations in DNA may modulate lung cancer process. Many studies reported that Vitamin D Receptor (VDR) gene polymorphisms may influence the cancer risk due to their antiproliferative, antiangiogenic, antimetastatic and apoptotic effects.

Material/methods: The genotype and haplotype frequencies of three polymorphisms of VDR, i.

Genetic variations in the hypoxia-inducible factor-1alpha gene and lung cancer.

Hypoxia-inducible factor-1 (HIF-1), an important genetic component of angiogenesis, becomes stable as a response to tumor hypoxia and facilitates tumor survival. The polymorphisms of the HIF-1alphagene may cause changes in the activity of this protein, which serves as a transcription factor for many genes in tumorigenesis. In this study, we have investigated the relationship between seven HIF-1alphapolymorphisms [C > T substitution in intron 8 (rs10873142), T418I (rs41508050) in exon 10, P564P (rs41492849), L580L (rs34005929), P582S (rs11549465), A588T (rs11549467) in exon 12 and dinucleotide GT repeats in intron 13 (rs10645014)] among lung cancer patients in the Turkish population.
