    Coronaphobia: A barrier to ongoing cancer treatment?
    (WILEY, 2022-01-01) Sonmez, Ozlem; Tezcanli, Evrim; Tasci, Elif Senocak; Kazanci, Hande Busra; Altinok, Ayse; Toklucu, Elvan; Tasci, Yusuf; Aydogdu, Cise; Aydin, Aysegul Bakir; Yuce, Sabiha; Oyan, Basak
    Introduction Increased stress levels caused by the pandemic might cause delays in cancer treatment. We conducted a survey among cancer patients undergoing treatment to evaluate their psychological wellbeing and treatment adherence during Coronavirus disease 19 (COVID-19) pandemic. Material and Methods Patients receiving active chemotherapy at a private oncology center between January and May 2021 were included. Healthy volunteers were employees of a district health directorate with no history of cancer or chronic disease. Treatment adherence was described as compliant if the prescribed treatment was received within a week and the information was gained from patient charts. Hospital anxiety and depression scale (HADS) and COVID-19 phobia scale (CP19-S) were administered to participants. Results 402 participants were included

    Clinical and radiological features of COVID-19 infection in pediatric hematology-oncology and transplant patients
    (CUKUROVA UNIV, FAC MEDICINE, 2022-01-01) Aygunes, Utku; Karagun, Barbaros Sahin; Sasmaz, Hatice Ilgen; Akbas, Tugana; Antmen, Bulent
    Purpose: The goal of this study is to explain the characteristics of COVID-19 in this demographic, as well as the impact it had on pediatric cancer care during the pandemic. Materials and Methods: Fifteen COVID-19 patients diagnosed were studied retrospectively. Clinical, laboratory and radiological data were collected in relation to 15 patients under the age of 18 who tested positive for SarsCoV-2. Results: Of the 12117 pediatric hemato-oncological patients tested for COVID-19, 1125 patients showed symptoms, and 14 tested positive. The majority of cases suffered minor illnesses. A total of ten children required inpatient care, five needed oxygen support, and four required mechanical ventilation and later died. It was noted that the duration of real-time polymerase chain reaction (RT-PCR) positivity was prolonged in patients receiving intensive chemotherapy and/or immunosuppressive therapy. Patients' chemotherapy was delayed in all 15 (100\%) Sars-CoV-2-positive patients. Although changes visible on chest computed tomography (CT) imaging of children were mainly milder than in adults, radiological findings were more severe in patients who received relatively intensive cancer treatment. Conclusion: Children who have been treated for cancer or who have undergone a hematopoietic stem cell transplantation (HSCT) may be at greater risk of severe COVID-19 and should be under constant observation.

    Correlation of anatomical involvement patterns of insular gliomas with subnetworks of the limbic system
    (AMER ASSOC NEUROLOGICAL SURGEONS, 2022-01-01) Ulgen, Ege; Aras, Fuat Kaan; Cosgun, Erdal; Ersen-Danyeli, Ayca; Dincer, Alp; Usseli, M. Imre; Ozduman, Koray; Pamir, M. Necmettin
    OBJECTIVE Gliomas frequently involve the insula both primarily and secondarily by invasion. Despite the high connectivity of the human insula, gliomas do not spread randomly to or from the insula but follow stereotypical anatomical involvement patterns. In the majority of cases, these patterns correspond to the intrinsic connectivity of the limbic system, except for tumors with aggressive biology. On the basis of these observations, the authors hypothesized that these different involvement patterns may be correlated with distinct outcomes and analyzed these correlations in an institutional cohort. METHODS Fifty-nine patients who had undergone surgery for insular diffuse gliomas and had complete demographic, pre- and postoperative imaging, pathology, molecular genetics, and clinical follow-up data were included in the analysis (median age 37 years, range 21-71 years, M/F ratio 1.68). Patients with gliomatosis and those with only minor involvement of the insula were excluded. The presence of T2-hyperintense tumor infiltration was evaluated in 12 anatomical structures. Hierarchical biclustering was used to identify co-involved structures, and the findings were correlated with established functional anatomy knowledge. Overall survival was evaluated using Kaplan-Meier and Cox proportional hazards regression analysis (17 parameters). RESULTS The tumors involved the anterior insula (98.3\%), posterior insula (67.8\%), temporal operculum (47.5\%), amygdala (42.4\%), frontal operculum (40.7\%), temporal pole (39\%), parolfactory area (35.6\%), hypothalamus (23.7\%), hippocampus (16.9\%), thalamus (6.8\%), striatum (5.1\%), and cingulate gyrus (3.4\%). A mean 4.2 +/- 2.6 structures were involved. On the basis of hierarchical biclustering, 7 involvement patterns were identified and correlated with cortical functional anatomy (pure insular {[}11.9\%], olfactocentric {[}15.3\%], olfactoopercular {[}33.9\%], operculoinsular {[}15.3\%], striatoinsular {[}3.4\%], translimbic {[}11.9\%], and multifocal {[}8.5\%] patterns). Cox regression identified hippocampal involvement (p = 0.006) and postoperative tumor volume (p = 0.027) as significant negative independent prognosticators of overall survival and extent of resection (p = 0.015) as a significant positive independent prognosticator. CONCLUSIONS The study findings indicate that insular gliomas primarily involve the olfactocentric limbic girdle and that involvement in the hippocampocentric limbic girdle is associated with a worse prognosis.
