COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been considered a public health emergency, extensively investigated by researchers. Accordingly, the respiratory tract has been the main research focus, with some other studies outlining the effects on the neurological, cardiovascular, and renal systems. However, concerning SARS-CoV-2 outcomes on skeletal muscle, scientific evidence is still not sufficiently strong to trace, treat and prevent possible muscle impairment due to the COVID-19. Simultaneously, there has been a considerable amount of studies reporting skeletal muscle damage in the context of COVID-19. Among the detrimental musculoskeletal conditions associated with the viral infection, the most commonly described are sarcopenia, cachexia, myalgia, myositis, rhabdomyolysis, atrophy, peripheral neuropathy, and Guillain-Barré Syndrome. Of note, the risk of developing sarcopenia during or after COVID-19 is relatively high, which poses special importance to the condition amid the SARS-CoV-2 infection. The yet uncovered mechanisms by which musculoskeletal injury takes place in COVID-19 and the lack of published methods tailored to study the correlation between COVID-19 and skeletal muscle hinder the ability of healthcare professionals to provide SARS-CoV-2 infected patients with an adequate treatment plan. The present review aims to minimize this burden by both thoroughly exploring the interaction between COVID-19 and the musculoskeletal system and examining the cutting-edge 3D cell culture techniques capable of revolutionizing the study of muscle dynamics.

e13616 Background: Lung cancer remains the main cause of cancer-related mortality globally, with non-small cell (NSCLC) accounting for the majority of cases. The advent of immunotherapy (IO) has expanded treatment options for advanced NSCLC. However, there are no bibliometric studies exploring NSCLC IO-based trials. We aimed to provide a systematic and comprehensive analysis of the design, reporting, population, and disparities of phase 3 trials investigating IO for advanced NSCLC. Methods: MEDLINE search was performed (last decade) for phase 3 trials reporting on patients with advanced (stage IIIA or higher) NSCLC. We assessed relationships between study outcomes, funding transparency, conflict of interest, journal impact factor (IF), region, gender of the first and last authors, population size, and ethnicity. Results: From 2012 to 2022, 2556 articles were screened and 81 were included. Overall survival (OS), followed by progression/disease-free survival (PFS) and overall/objective response (ORR) were the most commonly reported primary endpoints, representing 54%, 44%, and 15% respectively. The majority of the studies ( > 97%) had a funding sources statement and declared COI. Male first and last authorship represented 84% and 74% of studies, respectively. In 62% of trials reporting the patient’s ethnicity, white was the most common (65%). Regarding the source of funding, 74% of trials reported industry-only, 8% academia-only, 11% combined, 4% no funding received and 2.5% were not transparent. 98% of trials were from high-income countries (HIC), being the US (37%) and China (26%) the most reported. The mean number of authors with declared COI was 10.55 [0-25] and the mean total number of authors was 21.3 [5-76]. Publications journals' mean IF was 57.7 [2.1-202.7]. COI declaration was associated with publication in a journal with a higher IF compared to studies with no declared COI (p < 0.05). The journal IF was significantly higher in the US publications compared to China (p < 0.01). Trials assessing OS and PFS as their primary outcome were published with a higher IF in relation to assessing ORR only (p < 0.05). There was a significant association between the first and last authors' gender (p < 0.05), with a higher likelihood of matching genders (OR = 4,5 [1,3-14,4]). There was no association between the proportion of COI among authors, source of funding, and first author’s gender with journal IF. Conclusions: Phase 3 trials exploring IO for advanced NSCLC are majorly done in HIC, report industry funding and COI, and have males as the first and last authors. PFS is the primary outcome of almost 50% of the trials. We identified that among the primary outcomes studied, declaration of COI and author’s geographic affiliation may influence the publication’s IF. Sustained efforts are required to guarantee impartial reporting of clinical trial results and inclusive representation.
