This combination can yield a quadruple-rule-out computed tomography angiography (QRO-CT) technique.

[Evaluation of Pertussis Antibody Levels (Anti-PT IgG-Anti-FHA IgG) and Associated Factors in Maternal and Cord Blood].

Pertussis has a very high mortality and morbidity rate in early infancy. There are many strategies to protect babies from pertussis, maternal immunization is one of them. In this study, it was aimed to evaluate pertussis toxin immunoglobulin G (anti-PT IgG) and filamentous hemagglutinin immunoglobulin G (anti-FHA IgG) levels of pertussis antibody in maternal and cord blood samples and also to evaluate the factors that may be associated with maternal antibody positivity.

Virtual non-enhanced dual-energy computed tomography reconstruction: a candidate to replace true non-enhanced computed tomography scans in the setting of suspected liver alveolar echinococcosis.

Purpose: When a suspected hepatic alveolar echinococcosis (AE) lesion is detected on a contrast enhanced computed tomography (CT) scan, an additional triphasic or non-enhanced CT scan is required to determine the presence of calcification and enhancement. As a result, imaging costs and exposure to ionizing radiation will increase. We can create a non-enhanced series from routine contrast-enhanced images using dual-energy CT (DECT) and virtual non-enhanced (VNE) images.

Percutaneous management in hepatic alveolar echinococcosis: A sum of single center experiences and a brief overview of the literature.

Background: Hepatic alveolar echinococcosis (HAE) is a serious zoonotic infection that affects humans. It may have a tumor-like appearance at times. Percutaneous treatment of HAE patients is extremely relaxing for them.

Incidental findings on prostate MRI: a close look at the field of view in this anatomical region.

Magnetic resonance imaging (MRI) has been widely used as an advanced imaging modality to detect prostate cancer and indicate suspicious areas to guide biopsy procedures. The increasing number of prostate examinations with MRI has provided an opportunity to detect incidental lesions, and some might be very significant to elucidate patient symptoms or occult neoplastic process in the early stages. These incidental lesions might be located in the prostate gland, adjacent tissues, or organs around the prostate gland or out of the genitourinary system.

Going Back to Normal, But How? Re-opening Policies and the Standards for a New Normal.

Governments implemented to nonpharmacological methods and various limitation policies such as closing nonessential businesses, schools and limiting group gatherings, promoting social distancing, use of personal protective equipment, advising staying at home. These policies have caused various problems in social and economic life and gradual increase in psychosocial well-being problems. All societies yearningly are waiting for the COVID-19 pandemic to be brought under control and the measures to be lifted in order to return to their previous lives.

Cost Utility of Switching From Trivalent to Quadrivalent Influenza Vaccine in Turkey.

Objectives: Trivalent influenza vaccines (TIVs) are widely used but protect against only 1 of the 2 co-circulating influenza B virus lineages. Quadrivalent influenza vaccines (QIVs) include a B strain from each lineage to overcome mismatches. The main objective of this study was to determine the cost-utility and budget impact of switching from vaccination with TIV to QIV in the population recommended for influenza vaccination in Turkey.

Projecting the course of COVID-19 in Turkey: A probabilistic modeling approach.

Background/aim: The COVID-19 pandemic originated in Wuhan, China, in December 2019 and became one of the worst global health crises ever. While struggling with the unknown nature of this novel coronavirus, many researchers and groups attempted to project the progress of the pandemic using empirical or mechanistic models, each one having its drawbacks. The first confirmed cases were announced early in March, and since then, serious containment measures have taken place in Turkey.

Understanding dynamics of pandemics.

Along the centuries, novel strain of virus such as influenza produces pandemics which increase illness, death and disruption in the countries. Spanish flu in 1918, Asian flu in 1957, Hong Kong flu in 1968 and swine flu in 2009 were known pandemic which had various characteristics in terms of morbidity and mortality. A current pandemic is caused by novel corona virus originated from China.

Predictive Role of the Cervical Sympathetic Trunk Ischemia on Lower Heart Rates in an Experimentally Induced Stenoocclusive Carotid Artery Model by Bilateral Common Carotid Artery Ligation.

Bilateral common carotid artery ligation (BCCAL) leads to acute craniocervicocerebral ischemia, retrograde blood flow, increased blood pressure, and significant hemodynamic and histomorphological changes at the posterior cerebral vasculature. We examined the potential relationship between denervation injury following BCCAL-induced cervical sympathetic trunk (CST) ischemia and heart rate after permanent BCCAL. Rabbits (n = 25) were randomly divided into three groups: an unoperated control group (GI, n = 6); a sham-operated control group (GII, n = 6), and an experimental group subjected to BCCAL (GIII, n = 13); and then followed for one month.
