An overview on the evaluated video retrieval tasks at TRECVID 2022
The TREC Video Retrieval Evaluation (TRECVID) is a TREC-style video analysis
and retrieval evaluation with the goal of promoting progress in research and
development of content-based exploitation and retrieval of information from
digital video via open, tasks-based evaluation supported by metrology. Over the
last twenty-one years this effort has yielded a better understanding of how
systems can effectively accomplish such processing and how one can reliably
benchmark their performance. TRECVID has been funded by NIST (National
Institute of Standards and Technology) and other US government agencies. In
addition, many organizations and individuals worldwide contribute significant
time and effort. TRECVID 2022 planned for the following six tasks: Ad-hoc video
search, Video to text captioning, Disaster scene description and indexing,
Activity in extended videos, deep video understanding, and movie summarization.
In total, 35 teams from various research organizations worldwide signed up to
join the evaluation campaign this year. This paper introduces the tasks,
datasets used, evaluation frameworks and metrics, as well as a high-level
results overview.Comment: arXiv admin note: substantial text overlap with arXiv:2104.13473,

Wounding promotes ovarian cancer progression and decreases efficacy of cisplatin in a syngeneic mouse model
Abstract Background Primary cytoreductive surgery followed by adjuvant chemotherapy is the standard treatment for advanced epithelial ovarian cancer. The average interval between surgery and chemotherapy initiation is approximately 4-weeks at most centers; however, since surgery may accelerate residual tumor growth, a shorter interval may be more beneficial. Methods The murine ID8 cell model of ovarian cancer was used to examine the efficacy of cisplatin treatment administered perioperatively or 7 days after surgical wounding. Luciferase-expressing cells ID8 cells were injected intraperitoneally (i.p.) into female C57/Bl6 mice. Fourteen days post-injection, animals received an abdominal incision or anesthesia alone and received i.p. cisplatin either on the surgical day or 7 days later, or received no chemotherapy. Additional animals received cisplatin 28 days after wounding for comparison. Results Abdominal tumor mass increased 2.5-fold in wounded vs. unwounded animals as determined by bioluminescent in vivo tumor imaging. Cisplatin administered on the day of wounding decreased tumor burden by 50%, as compared to 90% in unwounded animals. Cisplatin on day 7 or day 28 decreased tumor burden by 80 and 37% respectively. Conclusions Surgical wounding increases ovarian tumor mass and decreases perioperative cisplatin efficacy in this animal model. Administration of cisplatin 1 week after surgery was more effective than cisplatin administered perioperatively or 4 weeks after surgery
