    Background: This study aimed to investigate the effect of cytoreductive nephrectomy (CN) on the survival outcomes of nivolumab used as a subsequent therapy after the failure of at least one anti-vascular endothelial growth factor (VEGF) agent in patients with metastatic clear-cell renal-cell carcinoma (ccRCC). Methods: We included 106 de novo metastatic ccRCC patients who received nivolumab after progression on at least one anti-VEGF agent. Multivariate Cox regression analysis was performed to investigate the factors affecting survival in patients receiving nivolumab. Results: Of the 106 de novo metastatic ccRCC patients, 83 (78.3%) underwent CN. There were no statistical differences between the two groups in terms of age, gender, Eastern Cooperative Oncology Group (ECOG) score, tumor size, International Metastatic RCC Database Consortium (IMDC) risk group, number of previous treatment lines, first-line anti-VEGF therapy, or metastasis sites (p = 0.137, p = 0.608, p = 0.100, p = 0.376, p = 0.185, p = 0.776, p = 0.350, and p = 0.608, respectively). The patients who received nivolumab with CN had a longer time to treatment discontinuation (TTD) [14.5 months, 95% confidence interval (CI): 8.6-20.3] than did those without CN 6.7 months (95% CI: 3.9-9.5) (p = 0.001). The median overall survival (OS) was 22.7 months (95% CI: 16.1-29.4). The patients with CN had a median OS of 22.9 months (95% CI: 16.3-29.4), while those without CN had a median OS of 8.1 months (95% CI: 5.6-10.5) (p = 0.104). In the multivariate analysis, CN [hazard ratio (HR): 0.521; 95% CI: 0.297-0.916; p = 0.024] and the IMDC risk score (p = 0.011) were statistically significant factors affecting TTD; however, the IMDC risk score (p = 0.006) was the only significant factor for overall survival. Conclusions: Our study showed that the TTD of nivolumab was longer in metastatic ccRCC patients who underwent cytoreductive nephrectomy.

    Prenatal Attachment and Mental Well-Being Among Expectant Fathers Amidst COVID-19: A Cross-Sectional Study
    (Springernature, 2023) Akdag, Berhan; Erdem, Dilek; Ipekten, Funda; Alpay, Emre Han; Yardimci, Figen; Bektas, Murat
    Background The COVID-19 pandemic has posed significant threats to global physical and mental health, notably impacting the psychological management of pregnancy. The mental health of parents plays a critical role in fostering the emotional bond with their unborn child, referred to as prenatal attachment. Despite the significance of this bond, research has primarily concentrated on maternal outcomes, often neglecting the paternal aspect during the pandemic. This study investigates the correlation between coronavirus disease 2019 (COVID-19) risk perception and paternal prenatal attachment, further exploring the mediating role of well-being within this association. Methods A total of 141 expectant fathers attending the gynecology and obstetrics outpatient clinic with their partners were recruited. Participants completed measures including the Paternal Antenatal Attachment Scale (PAAS), the World Health Organization Well-being Index (WHO-5), and the COVID-19 Perceived Risk Scale (CPRS). Results Data analysis revealed a significant negative correlation between COVID-19 risk perception and well-being (f3 =-.34, p < .001). There was a positive correlation between well-being and prenatal attachment (f3 = .37, p = .002). The prenatal attachment was also positively linked to COVID-19 risk perception (f3 = .20, p = .047). Furthermore, well-being mediated the relationship between COVID-19 risk perception and prenatal attachment. Conclusion The findings underscore the potential of the COVID-19 risk perception to disrupt the prenatal attachment process for expectant fathers by interfering with psychological well-being. However, it can also promote prenatal attachment through various mechanisms. Consequently, acknowledging and understanding the experiences of fathers during pregnancy is of paramount importance. Future longitudinal studies are necessitated to examine the parent-child relationship dynamics that have evolved under the influence of the pandemic.
