Background The number of COVID-19 cases has been decreasing recently, and the restrictions are waived in many countries. The data about vaccine efficacy are essential to be prepared for the future even if the pandemic ends and the disease becomes endemic. Aims The aim of this study was to define demographic and laboratory data for disease severity among vaccinated COVID-19 cases who were hospitalized. Study Design This is a retrospective cohort study. Methods SARS-CoV-2 polymerase chain reaction–positive patients who were fully vaccinated (2 doses of vaccines and 3 doses of vaccines) and had been hospitalized at least 15 days after the last vaccine dose were enrolled in this study. Patients' data including laboratory parameters were retrieved, and descriptive statistics and comparison of variables were calculated. Results Between September 1, 2021, and February 28, 2022, 685 patients (mean age, 67.84 years; 50.8% female) were hospitalized. Inactivated whole-virion SARS-CoV-2 vaccine (CoronaVac) had been administered to 467 of the patients (68.4%), BNT162b2 mRNA vaccine (Pfizer-Pfizer-BioNTech) had been administered to 107 of the patients (15.6%), and to 111 of the patients (16%), a combination of 2 vaccines had been administered. At least 1 comorbidity was present in 160 participants (23%) and more than 4 comorbidities in 46 patients (6.6%). The most common comorbidity was hypertension (349, 50.2%). The presence of comorbidities was significantly higher in patients having 3 doses of vaccine. Increased ferritin levels were determined in 56.4% of the patients, increased D-dimer levels in 69.9% of the patients, increased C-reactive protein levels in 79.7% of the patients, and increased procalcitonin levels in 61.5% of the patients. A total of 36.4% of the patients had decreased lymphocyte counts, 20% had low lymphocyte/monocyte ratio, and 22% had decreased neutrophil/lymphocyte ratio. The only parameter that was significantly higher in patients having 3 vaccine doses was procalcitonin. Mean duration of hospitalization was 9.68 ± 7.29 days. In the CoronaVac and Pfizer-BioNTech groups, 68.5% and 21.4%, respectively, of the patients were older than 65 years. Seventeen (3.6%) patients in the CoronaVac group, 6 (5.4%) patients in the combination group, and 3 (2.8%) patients in Pfizer-BioNTech group had been admitted to the intensive care unit. Mortality rate was 0.3% (2 of 685 patients). Conclusions The incidence of severe COVID-19 disease among fully vaccinated patients is low even in the presence of comorbidities, older age, and presence of abnormal laboratory parameters, regardless of the vaccine type.

Vancomycin-resistant enterococci (VRE) may lead to prolonged hospitalization stay and increase the risk of infections especially in immunosuppressed patients. Rectal swab screening and contact isolation are advised to prevent the spread of VRE colonisation and infection among patients. Colonisation screening policy is carried out according to the guidelines applied by the hospital infection committees. In this retrospective study, it was aimed to determine the rate of vancomycinresistant enterococci (VRE) in rectal swab samples and to evaluate the relationship with VRE colonization and infection

Objective: In this study it was aimed to evaluate the distribution of Candida species and their antifungal susceptibility profiles in

Achromobacter türleri Gram negatif, katalaz, oksidaz ve sitrat pozitif, fermentatif olmayan bakterilerdir. Toplum kökenli ya da hastane kaynaklı enfeksiyonlara sebep olabilmektedir. Hem immünokompetan hem de immün yetmezlikli kişilerde enfeksiyonlara sebep olabilmekle birlikte kistik fibrozis (KF) hastalarını enfekte etmeleri durumunda, KF hastalarının akciğer fonksiyonlarını kötüleştirdiğinden ve daha sık pulmoner alevlenmeye neden olduğundan bu hasta grubunda özellikle önem taşımaktadır. Bu retrospektif çalışmada, Marmara Üniversitesi Eğitim ve Araştırma Hastanesi’nde 2017-2021 yıllarında Achromobacter türleri izole edilen hastaların verileri analiz edilmiştir. Altta yatan hastalıkların varlığına göre Achromobacter türlerinin izolasyon sıklığı, hastalara ait demografik veriler ve antimikrobiyal duyarlılık sonuçları irdelenmiştir. İzolatların tür düzeyinde tanımlaması, matriks ile desteklenmiş lazer desorpsiyon/iyonizasyon uçuş zamanı kütle spektrometresi (MALDI-TOF MS, VITEK MS, BioMérieux, Fransa) ile yapılmıştır. Antimikrobiyal duyarlılık testleri, disk difüzyon metodu ile çalışılmıştır. İstatistiksel analizler için SPSS (Statistical Package for Social Sciences) for Windows 24.0 programı kullanılmıştır. Toplam 148 hastadan 318 Achromobacter izolatı elde edilmiştir. Hastaların %29.7’si kistik fibrozis (KF); %70.3’ü ise KF dışı hastalar olmasına rağmen izolatların %51.6’sı KF hastalarına aittir (P=0.63). En sık gönderilen örnek türü, solunum yollarına ait örnekler olup (%78), KF hastalarında gönderilen örneklerin tümü solunum örneği iken; KF dışı hastalarda bu oran %54.5’tir (P
