Antibody Response to COVID-19 Vaccines in Healthcare Workers: Which One is More Successful? Homologous or Heterologous?

Objectives: We aimed to determine the antibody levels created by COVID-19 vaccination in healthcare workers and the factors affecting the antibody response.

Methods: Our research is a single-center, observational study that was prospectively designed and retrospectively analyzed at the beginning of the COVID-19 pandemic, and included 103 healthcare workers who received the three-dose regimen of COVID-19 vaccine. In accordance with the recommendations of the Ministry of Health of Turkey, the first two doses of CoronaVac vaccine were administered routinely, while the booster dose was given as BioNTech or CoronaVac (heterologous or homologous vaccination) depending on the preference of the volunteers.

An investigation of the changes in mechanical properties of the orofacial and neck muscles between patients with myogenous and mixed temporomandibular disorders.

Objective: To investigate the possible changes in the mechanical properties of the orofacial and neck muscles in patients with temporomandibular disorders (TMD).

Methods: The study included a total of 98 females. Females were divided into three groups as myogenous TMD, mixed TMD, and healthy controls.

Changes in antimicrobial resistance and outcomes of health care-associated infections.

To describe the change in the epidemiology of health care-associated infections (HAI), resistance and predictors of fatality we conducted a nationwide study in 24 hospitals between 2015 and 2018. The 30-day fatality rate was 22% in 2015 and increased to 25% in 2018. In BSI, a significant increasing trend was observed for Candida and Enterococcus.

Treatment of upper extremity lymphedema with minimally invasive supermicrosurgery technique.

A 51-year-old female patient was admitted to our clinic with numbness and anesthesia in the left upper extremity. There was widespread peripheral edema above and below the left elbow. Symptoms of the patient were associated with axillary lymphatic nodular dissection during previous the mastectomy operation.

A life-threatening brainstem compression by cerebral Echinococcus granulosus.

Cystic echinococcosis (CE) is a zoonotic disease caused by Echinococcus granulosus. It is of worldwide importance, and is widespread in the Mediterranean region and Middle East. This tapeworm shows great intraspecific variation in relation to host specificity, epidemiology and morphology.

West nile virus infection in the Mesopotamia region, Syria border of Turkey.

We described the serological prevalence of West Nile Virus (WNV) antibodies among the human population in a historical and strategic region of Turkey. A serologic survey was conducted based on suspected cases in April, 2009, in the Mesopotamia region of Turkey, in the villages that were located alongside the Zergan River. All the sera were tested by enzyme-linked immunosorbent assay ELISA (Euroimmune™), and the positive samples were tested by immunofluorescent assay (IFA; Euroimmune™).

Clinical significance of TT virus infection in children with chronic hepatitis B.

Background: The pathogenic role of TT virus (TTV) is not clear in patients with chronic hepatitis B. The aims of the present study were to determine the frequency of TTV positivity in serum and saliva samples and the possible role of TTV in children with chronic hepatitis B.

Methods: Sera and saliva from 29 healthy children and 25 children with chronic hepatitis B were tested for TTV-DNA by means of real-time polymerase chain reaction (PCR).
