391, p  less then  .001), greater depressive symptoms (β = 0.443, p  less then  .001), and reduced mobility (β = -0.226, p = .004) (adjusted R2 = 0.613, F = 16.476, p  less then  .001). Conclusions Children and adolescents with cancer experience multiple, intersecting troubling symptoms during their treatment. There is a need to attend to the biopsychosocial aspects of care for children and adolescents during active cancer treatment. To reduce pediatric oncology patients' fatigue level, clinicians could develop culturally sensitive interventions to alleviate children's pain interference, treat depressive symptoms, and maximize their physical mobility.
  Malignant change in vestibular schwannoma is rare and intracranial metastatic deposits have not been reported.
 
  We report the case of a 64 year old woman with a benign vestibular schwannoma who underwent translabyrinthine excision in 1996 and Gamma Knife
  radiosurgery (Elekta AB, Stockholm, Sweden) (GKRS) in 2006. She presents 10 years after GKRS with progressive neurological deterioration. Histopathologic analysis confirms a malignant peripheral nerve sheath tumour, WHO grade IV with subsequent metastatic spread to the left thalamus confirmed on biopsy.
 
  We report a rare case of a vestibular schwannoma metastasizing with histological confirmation. It also reminds us of malignant conversion of a benign vestibular schwannoma following GKRS and subsequent aggressive behaviour, with poor prognosis.

  Increased understanding of the interactive mechanisms between tumors and the immune system led to the development of immune checkpoint inhibitors, which have revolutioned the treatment of metastatic melanoma and subsequently many other tumors. In 2014, nivolumab and pembrolizumab, two checkpoint inhibitors binding to PD-1, were approved for the treatment of metastatic melanoma. Since then, a plethora of new molecules have enriched the armamentarium against melanoma.
 
  This review summarizes the last updates about treatment with nivolumab and pembrolizumab, data on other PD-1/PDL-1 agents such as spartalizumab and atezolizumab and emerging compounds, new combinations with NKTR-214, anti LAG-3, anti IDO-1 and TVEC, new checkpoint inhibitors (e.g. TIM-3 or TIGIT) and other new molecules for the treatment of metastatic melanoma.
 
  Currently, several ongoing clinical trials are investigating novel molecules, or immunotherapy combinations, in order to achieve even better survival outcomes for patients, overcoming resistance mechanisms and improving toxicity profiles. The challenge in the near future will be to select the most appropriate treatments according to the specific characteristics of the patients.

Each country has implemented different strategies to control and reduce the spread of disease. Here, the association between prevalence number and health policies is evaluated by comparing 2 groups of countries (1) Italy, the United States of America, Germany, Spain, and India with a higher prevalence than a linear trend line; and (2) Singapore and China with a lower or equal prevalence than linear forecasts. A rapid overview revealed that many countries have similar strategies for controlling COVID-19, including the suspension of air travel, the lockdown on the cities with the most cases detected, active case findings, monitoring of close contacts, and raising public awareness. Also, they used a gradual and phased plan to reopen activities. So, the difference between countries in the burden of COVID-19 can be attributable to the strict mode and nonstrict mode of implementation of strategies. Limitations at the national levels call for systemic rather than regional strategies.Accumulating evidence has revealed that long noncoding RNAs (lncRNAs) play essential roles in regulating cellular process of various cancers. There have been many studies on the biological functions of lncRNAs in colorectal cancer (CRC). In this research, we explored the role and mechanism of lncRNA ovarian tumor domain containing 6B antisense RNA1 (OTUD6B-AS1) in CRC. Here, we detected OTUD6B-AS1 expression in CRC tissues and cells by RT-qPCR. Functional experiments were performed to test alterations in different cellular processes. Moreover, to verify the binding ability among the indicated RNA molecules, we carried out RIP, RNA pull-down and luciferase reporter assays. According to our data, OTUD6B-AS1 expression was low in CRC tissues and cells. Functionally, overexpression of OTUD6B-AS1 inhibited cell proliferation, migration, invasion and EMT, and promoted cell apoptosis. Bioinformatic analysis and mechanistical experiments confirmed that OTUD6B-AS1 could act as a competitive endogenous RNA (ceRNA) to upregulate Proline-Rich Nuclear Receptor Coactivator 2 (PNRC2) expression by sequestering miR-21-5p. Further rescue experiments validated the inhibitory function of the OTUD6B-AS1/miR-21-5p/PNRC2 axis in cellular process of CRC. Overall, OTUD6B-AS1 inhibits cellular development in CRC by sponging miR-21-5p and upregulating PNRC2, providing a novel insight into the exploration on CRC treatment.
  Sickle cell disease (SCD) is a lifelong blood disorder affecting approximately 100,000 individuals in the United States (US). A number of new treatments have recently become available to improve SCD clinical outcomes, but it is unclear how treatment innovations that reduce disease severity could affect patients' humanistic and economic outcomes.
 
  To answer this question, an online survey of US adult residents with a self-reported SCD diagnosis was conducted. Humanistic outcomes based on health-related quality of life (HRQoL)) were assessed during and outside of vaso-occlusive crises (VOCs). Economic outcomes were measured by annual household income and whether the respondent received disability insurance.
 
  Among the 301 respondents completing the survey, average age was 34.4 years and 73.4% were female. Average HRQoL, measured using health utilities, were 0.311 (95% CI 0.286, 0.337) during a VOC and 0.738 (0.720, 0.756) not during a VOC. The likelihood of claiming disability insurance was correlated with more frequent VOCs (0 VOCs 12% vs.
