BACKGROUND In the context of the Coronavirus disease 2019 (COVID-19) pandemic, it has been reported that elderly patients are particularly at risk of developing severe illness and exhibiting increased mortality. While many studies on hospitalized elderly patients with COVID-19 have been published, limited information is available on the characteristics and clinical outcomes of those elderly patients admitted to intensive care unit (ICU). AIM To review the available evidence of the clinical data of elderly patients admitted to the ICU due to COVID-19. METHODS We searched for published articles available in English literature to identify those studies conducted in critically ill patients admitted to the ICU due to COVID-19, either exclusively designed for the elderly or for the whole ICU population with COVID-19, provided that analyses according to the patients’ age had been conducted. RESULTS Only one study exclusively focusing on critically ill elderly patients admitted to the ICU due to COVID-19 was found. Eighteen additional studies involving 17011 ICU patients and providing information for elderly patients as a subset of the whole study population have also been included in the present review article. Among the whole patient population, included in these studies, 8310 patients were older than 65 years of age and 2630 patients were older than 70 years. Clinical manifestations were similar for all patients; however, compared to younger ones, they suffered from more comorbidities and showed a varied, albeit high mortality. CONCLUSION In summary, at present, although elderly patients constitute a considerable proportion of critically ill patients admitted to the ICU due to severe COVID-19, studies providing specific information are limited. The evidence so far suggests that advanced age and comorbidities are associated with worse clinical outcome. Future studies exclusively designed for this vulnerable group are needed.
Background: c-Myc is a proto-oncogene located on human chromosome 8. It encodes a transcriptional factor which regulates the expression of approximately 10% to 15% of human genes, playing a crucial role in cell growth, differentiation, cellular metabolism, apoptosis, and cell transformation. The aim of this study is to correlate the expression of c-Myc in patients suffering from urinary bladder transitional cell carcinoma with tumor grade, stage, and lymph node metastases. Materials and methods: Formalin-fixed, paraffin-embedded tissue samples were obtained from 54 consecutive patients who underwent transurethral resection of bladder tumor or radical cystectomy (RC) as treatment for urinary bladder transitional cell carcinoma. Immunohistochemistry was performed using c-Myc monoclonal antibody and c-Myc expression was then analyzed for correlation with tumor stage, grade, and lymph node metastases. Results: From a total of 54 patients, 42 (77.8%) had c-Myc positive staining and 12 (22.2%) were c-Myc negative. In the c-Myc positive group, 28 patients (66.7%) had low grade tumors and 33 (78.6%) presented with non-muscle-invasive disease ( p < 0.05). In the c-Myc negative group, 10 patients (83.3%) had high-grade disease and 8 (66.7%) presented with muscle-invasive disease ( p < 0.05). Lymph node metastases were evaluated in 17 patients who underwent RC. Of these, 5 had lymph node metastases, 4 of whom had c-Myc negative staining ( p < 0.05). Conclusions: In our study, c-Myc negative staining was associated with higher grade and higher stage disease. On the contrary, most c-Myc positive tumors were low grade and non-muscle-invasive disease. In patients who underwent RC, c-Myc negative staining was associated with lymph node metastases.
Background Since COVID–19 was declared a pandemic on March 11, 2020, health care systems worldwide have been under significant strain. Although urology is not on the frontline of care for patients with COVID-19, every practicing urologist has been affected by the global outbreak. The objective of this review is to evaluate the impact of COVID–19 pandemic on urology residency training programs. Methods We reviewed the current evidence on urology residency training during the COVID-19 pandemic. Relevant databases (MEDLINE, Scopus, Cochrane Library) were searched for articles published to June 2021 that included residents’ or directors’ opinions on their residency training programs during the COVID-19 crisis. Results The literature search identified 72 articles. Fifteen studies including more than 2500 residents were eligible for inclusion in the analysis. During the pandemic, learning activities carried out by urology residents have been extensively affected. Worldwide, operation volume has decreased, especially for procedures in which residents were directly involved. Similarly, there has been a decline in most academic activities, and many studies have reported the negative impact on residents’ mental well-being and lifestyle. On the other hand, the lockdown provided an opportunity to review the current training system and to increase the implementation of tools such as telemedicine and smart-learning surgical skill training programs. Conclusion The COVID-19 pandemic has resulted in significant changes in urology residency programs worldwide, which have had a negative impact on surgical training and academic activities. Residents’ well-being and mental health have also been put at risk. However, this unprecedented situation has also generated new online learning modalities and technological innovations in the field of training in urology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
