Objective: The study aimed to identify predictors of advanced fibrosis score and histological activity index (HAI) in HBeAg-positive patients to facilitate early disease detection and reduce the need for invasive biopsies.

Materials And Methods: The single-center retrospective study included treatment-naïve HBeAg-positive chronic hepatitis B (CHB) patients. Patients with HAI ≥6 and/or fibrosis ≥2 were considered to have significant liver damage.

Unlabelled: The effect of COVID-19 on the outcomes of patients with Staphylococcus aureus bacteremia is still unknown.

Aim: In this study, we aimed to determine associated factors for mortality in patients with S. aureus bacteremia and to explore the impact of prior COVID-19.

Objective: This study aimed to determine the predictors for significant hepatic abnormality (SHA), a treatment indication, by assessing demographic, laboratory, and radiological results of chronic hepatitis B (CHB) patients who underwent liver biopsy.

Materials And Methods: In this retrospective study, individuals with untreated hepatitis B e-antigen (HBeAg)-negative CHB infection were enrolled. Multivariate analysis modeling was conducted with parameters identified as predictors for SHA in univariate analysis.

Objective: Predictors of mortality that indicate disease severity plays an important role in COVID-19 management and treatment decisions. This study aimed to investigate the association between fibrosis-4 (FIB-4) score, aspartate aminotransferase-to-platelet ratio index (APRI), and novel biomarker-based score (SAD-60) with mortality in COVID-19 patients treated in a tertiary hospital.

Materials And Methods: In this single-center retrospective study, patients ≥18 years of age who were admitted to our hospital for COVID-19 between December 1 and 31, 2021, were included.

Objective: There are limited data on non-alcoholic fatty liver disease in chronic hepatitis B virus infection. We aimed to determine the predictors for non-alcoholic fatty liver disease in patients with treatment-naïve chronic hepatitis B virus infection.

Methods: All consecutive treatment-naïve patients with chronic hepatitis B virus infection at the Haseki Training and Research Hospital between October 1, 2021, and September 31, 2022, were retrospectively enrolled.

Objective: We aimed to identify a rapid, accurate, and accessible biomarker in the early stages of COVID-19 that can determine the prognosis of the disease in cancer patients.

Methods: A total number of 241 patients with solid cancers who had a COVID-19 diagnosis between March 2020 and February 2022 were included in the study. Factors and ten different markers of inflammation were analyzed by year of diagnosis of COVID-19 and grouped by severity of infection.

We aimed to explore the prevalence of prolonged symptoms, pulmonary impairments and residual disease on chest tomography (CT) in COVID-19 patients at 6 months after acute illness. In this prospective, single-center study, hospitalized patients with radiologically and laboratory-confirmed COVID-19 were included. A high proportion of the 116 patients reported persistent symptoms (n = 54; 46.

Background: In this study, we presented two cases of late diagnosed complicated oculoglandular tularemia and reviewed the clinical features of oculoglandular tularemia in cases reported in the last ten years.

Method: Tularemia was diagnosed when serum microagglutination test (MAT) was ≥ 1/160 titer or when there was at least a four-fold increase in MAT titers measured over a two-week interval. We searched the oculoglandular tularemia cases reported in the last 10 years in the PubMed and Google Academic engines.

The authors aimed to investigate the relationship between ABO/Rhesus blood types and the risk of SARS-CoV-2 infection and hospitalization in healthcare workers (HCWs). This study compared HCWs with (n = 510) and without (n = 2318) SARS-CoV-2 infection. Risk factors for SARS-CoV-2 infection and hospitalization in HCWs were shown as odds ratios with 95% CI.

Objective: Positive results of the serum tube agglutination test that persist after treatment may be interpreted by clinicians as treatment failures. Therefore, our study examined the value of serum tube agglutination test in demonstrating treatment success.

Methods: In this retrospective study conducted at a single center, the pre- and post-treatment serum tube agglutination test titers of patients diagnosed with brucellosis were compared.

This study was designed to investigate the effectiveness of CoronaVac in preventing COVID-19 in healthcare workers (HCWs) during the Alpha variant-dominant period. Follow-up was initiated 14 days after the second dose for double-dose vaccinated HCWs and on 25 February 2021, for the unvaccinated group. The incidence rate ratio was calculated to estimate the unadjusted effectiveness.

The authors aimed to determine the efficacy of frequently used antibiotics, alone or in combination, against biofilms of ventilator-associated pneumonia isolates. The authors determined the MICs, minimum biofilm inhibitory concentrations and minimum biofilm eradication concentrations of meropenem, ciprofloxacin and colistin as well as their combinations against planktonic forms and biofilms of , and clinical isolates. Generally, the minimum biofilm inhibitory concentrations and minimum biofilm eradication concentrations of the antibiotics were 1000-fold higher than their MICs, and synergy was provided by different concentrations of meropenem-colistin and meropenem-ciprofloxacin combinations with checkerboard and time-kill curve methods.

Early diagnosis of organ involvement and bacteremia in brucellosis increases treatment success and may prevent poor clinical outcomes. This study aimed to investigate the predictors of focal involvement and bacteremia in patients with brucellosis. A total of 139 brucellosis patients aged 16 years and older were included in the study.

Article Synopsis
  • A study was conducted to develop a new risk score, named SAD-60, to predict mortality in hospitalized COVID-19 patients, involving 1,013 participants with an average age of 60.5 years.
  • The research found that factors like oxygen saturation, albumin levels, D-dimer, and age were significant predictors of in-hospital death, with 12.2% of patients dying.
  • The SAD-60 score demonstrated a better predictive ability for mortality than existing scores such as CURB-65, NEWS2, and qSOFA, suggesting it could be a valuable tool in clinical settings.

Article Synopsis
  • - The study compared clinical, laboratory, and radiological findings between confirmed COVID-19 patients (338) and unconfirmed ones (282) at a single center, involving a total of 620 patients.
  • - Confirmed COVID-19 patients had more frequent close contacts with positive cases, and symptoms like myalgia and dyspnea, along with lower blood cell counts, were significant indicators of infection in the univariate analysis.
  • - The study concluded that while routine blood tests can help differentiate COVID-19 from other respiratory ailments early on, PCR tests remain essential for an accurate COVID-19 diagnosis.

We aimed to determine the prognostic values of the National Early Warning Score 2 (NEWS2) and laboratory parameters during the first week of COVID-19. All adult patients who were hospitalized for confirmed COVID-19 between 11 March and 11 May 2020 were retrospectively included. Overall, 611 patients were included.

We aimed to determine the predictors of intensive care unit (ICU) admission or death in patients with coronavirus disease 2019 (COVID-19) pneumonia. This retrospective, single-center study included patients aged ≥18 years who were diagnosed with COVID-19 pneumonia (laboratory and radiologically confirmed) between March 9 and April 8, 2020. The composite endpoint was ICU admission or in-hospital mortality.
