    Objective: Patients with solid malignancies are more vulnerable to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection than the healthy population. The outcome of SARS-CoV-2 infection in highly immunosuppressed populations, such as in patients with hematological malignancies, is a point of interest. We aimed to analyze the symptoms, complications, intensive care unit admissions, and mortality rates of patients with hematological malignancies infected with SARS-CoV-2 in Turkey. Materials and Methods: In this multicenter study, we included 340 adult and pediatric patients diagnosed with SARS-CoV-2 from March to November 2020. Diagnosis and status of primary disease, treatment schedules for hematological malignancies, time from last treatment, life expectancy related to the hematological disease, and comorbidities were recorded, together with data regarding symptoms, treatment, and outcome of SARS-CoV-2 infection. Results: Forty four patients were asymptomatic at diagnosis of SARS-CoV- 2 infection. Among symptomatic patients, fever, cough, and dyspnea were observed in 62.6%, 48.8%, and 41.8%, respectively. Sixty-nine (20%) patients had mild SARS-CoV-2 disease, whereas moderate, severe, and critical disease was reported in 101 (29%), 71 (20%), and 55 (16%) patients, respectively. Of the entire cohort, 251 (73.8%) patients were hospitalized for SARS-CoV-2. Mortality related to SARS-CoV-2 infection was 26.5% in the entire cohort; this comprised 4.4% of those patients with mild disease, 12.4% of those with moderate disease, and 83% of those with severe or critical disease. Active hematological disease, lower life expectancy related to primary hematological disease, neutropenia at diagnosis of SARS-CoV-2, ICU admission, and first-line therapy used for coronavirus disease-2019 treatment were found to be related to higher mortality rates. Treatments with hydroxychloroquine alone or in combination with azithromycin were associated with a higher rate of mortality in comparison to favipiravir use. Conclusion: Patients with hematological malignancy infected with SARS-CoV-2 have an increased risk of severe disease and mortality.

    Disturbed endometrial NF-?B expression in women with recurrent implantation failure
    (Verduci Publisher, 2016) Erşahin, Aynur Adeviye; Acet, Mustafa; Acet, Tuba; Yavuz, Yasemin
    OBJECTIVE: This study was planned to investigate whether expression levels of endometrial NF-?B1 and NF?B p65 changes in women with recurrent implantation failure (RIF). PATIENTS AND METHODS: The study group consists of 30 RIF patients having at least three previous failed IVF cycles. The control group comprises of 30 patients having one or no previous failed attempt. Endometrial samples were obtained from all participants during hysteroscopy at the late follicular phase. Samples underwent ELISA analysis and immunohistochemical staining. The semi-quantitative H-Score method was used for analyzing the intensity of endometrial NF-?B p65 expression. RESULTS: The concentrations of endometrial NF-?B1 were found to be significantly increased when compared to control subjects. Likewise, significantly increased NF-?B p65 immunoreactivity was detected in the cytoplasm of luminal and glandular epithelial cells. The H-Score of NF- ?B p65 in RIF women was found to be significantly increased when compared to control group. CONCLUSIONS: Increased levels of NF-?B1 and NF-?B p65 in the endometrium of RIF women can disturb physiological inflammation which is known to be positive modulator of endometrial receptivity.

    Impact of endometrioma resection on eutopic endometrium metabolite contents: Noninvasive evaluation of endometrium receptivity
    (Sage Publications Inc, 2017) Erşahin, Aynur; Çelik, Önder; Acet, Mustafa; Erşahin, Süphan; Acet, Tuba; Kara Bozkurt, Duygu; Yavuz, Yasemin; İlhan, Selçuk
    The aim of this study was to determine whether endometrioma resection alters most commonly defined endometrial metabolites, lactate (Lac), N-acetylaspartate (NAA), creatine 1 (Cr1), creatine 2 (Cr2), and choline (Cho) during the window of implantation. Twenty patients with uni- or bilateral endometrioma and 7 patients having nonendometriotic benign ovarian cyst were included. Midluteal phase magnetic resonance spectroscopy analysis of eutopic endometrium was performed before surgery. Second spectrum of endometrium was obtained 3 to 5 months after laparoscopic endometrioma resection. Pre- and postoperative endometrial peaks of Lac, NAA, Cr, and Cho were measured in units and denominated in parts per million (ppm). Compared to preoperative peak values, significantly decreased NAA, Lac, and Cr1 signals were noted in patients undergoing endometrioma surgery. Nearly 5-fold decline in the NAA signal occurred after endometrioma surgery (1.94 +/- 3.24 vs 0.37 +/- 0.55). Likewise, 2.5-fold decline in Lac signals was noted after endometrioma resection (2.81 +/- 2.64 vs 1.06 +/- 1.88). Both uni- and bilateral endometrioma affected endometrium signals the same. The peak intensity of Cho, Cr1, Cr2, NAA, and Lac did not alter significantly after nonendometriotic cyst surgery. Endometrioma surgery straightens endometrial NAA, Lac, and Cr1 peaks, suggesting improvement in endometrial receptivity.
