Obstacles to successful settlement-social isolation, language hardship, issues with employment, housing questions, transportation, barriers to health, education and government service access-all potentially play a role in emerging physical and mental health problems. The objective of this scoping review is to map the available evidence in order to provide an overview of the services and resources offered to refugees, immigrants and other newcomers by settlement agencies to support emotional wellness and well-being.

The protocol to be followed for this scoping review is based on the Joanna Briggs Institute to provide a map of the current and emergent literature, and examine the extent, range and nature of this literature. The proposed scoping review will also identify the gaps in research pertaining to the emotional wellness of refugees, immigrants and other newcomers as well as summarise and disseminate research findings and provide direction for future reviews. Key databases for this scoping review incluarch will not involve human or animal subjects. The research is a scoping review, and thus relies on published and grey literature studies and documents. The findings of this proposed scoping review will be disseminated through future publications as well as presentations to relevant stakeholders, including immigrant serving agencies. We anticipate that this scoping review will identify gaps in research pertaining to the emotional wellness of refugees, immigrants and other newcomers. The results of this review will be the first comprehensive recent survey of emotional wellness practices employed by settlement agencies.Despite widespread utilization of immunotherapy, treating immune-cold tumors has proved to be a challenge. Here, we report that expression of the immune checkpoint molecule B7-H4 is prevalent among immune-cold triple-negative breast cancers (TNBC), where its expression inversely correlates with that of PD-L1. Glycosylation of B7-H4 interferes with its interaction/ubiquitination by AMFR, resulting in B7-H4 stabilization. B7-H4 expression inhibits doxorubicin-induced cell death through the suppression of eIF2α phosphorylation required for calreticulin exposure vis-à-vis the cancer cells. NGI-1, which inhibits B7-H4 glycosylation causing its ubiquitination and subsequent degradation, improves the immunogenic properties of cancer cells treated with doxorubicin, enhancing their phagocytosis by dendritic cells and their capacity to elicit CD8+ IFNγ-producing T-cell responses. In preclinical models of TNBC, a triple combination of NGI-1, camsirubicin (a noncardiotoxic doxorubicin analogue) and PD-L1 blockade was effective in reducing tumor growth. Collectively, our findings uncover a strategy for targeting the immunosuppressive molecule B7-H4. SIGNIFICANCE This work unravels the regulation of B7-H4 stability by ubiquitination and glycosylation, which affects tumor immunogenicity, particularly regarding immune-cold breast cancers. The inhibition of B7-H4 glycosylation can be favorably combined with immunogenic chemotherapy and PD-L1 blockade to achieve superior immuno-infiltration of cold tumors, as well as improved tumor growth control.See related commentary by Pearce and Läubli, p. 1789.This article is highlighted in the In This Issue feature, p. 1775.Epigenetic allele diversity is linked to inferior prognosis in acute myeloid leukemia (AML). However, the source of epiallele heterogeneity in AML is unknown. Herein we analyzed epiallele diversity in a genetically and clinically annotated AML cohort. Notably, AML driver mutations linked to transcription factors and favorable outcome are associated with epigenetic destabilization in a defined set of susceptible loci. In contrast, AML subtypes linked to inferior prognosis manifest greater abundance and highly stochastic epiallele patterning. We report an epiallele outcome classifier supporting the link between epigenetic diversity and treatment failure. Mouse models with TET2 or IDH2 mutations show that epiallele diversity is especially strongly induced by IDH mutations, precedes transformation to AML, and is enhanced by cooperation between somatic mutations. Furthermore, epiallele complexity was partially reversed by epigenetic therapies in AML driven by TET2/IDH2, suggesting that epigenetic therapy might function in part by reducing population complexity and fitness of AMLs. SIGNIFICANCE We show for the first time that epigenetic clonality is directly linked to specific mutations and that epigenetic allele diversity precedes and potentially contributes to malignant transformation. Furthermore, epigenetic clonality is reversible with epigenetic therapy agents.This article is highlighted in the In This Issue feature, p. 1775.Lung cancer researcher Solange Peters, MD, PhD, discusses the intersection of COVID-19 and cancer, as well as her research on immunotherapy biomarkers.
Ulcerative colitis (UC) is a lifelong, relapsing-remitting disease. Patients non-responsive to pharmacological treatment may require a colectomy. We estimated pre-colectomy and post-colectomy healthcare resource utilisation (HCRU) and costs in England.

A retrospective, longitudinal cohort study indexing adult patients with UC undergoing colectomy (2009-2015), using linked Clinical Practice Research Datalink/Hospital Episode Statistics data, was conducted. HCRU, healthcare costs and pharmacological treatments were evaluated during 12 months prior to and including colectomy (baseline) and 24 months post-colectomy (follow-up; F-U), comparing baseline/F-U, emergency/elective colectomy and subtotal/full colectomy using descriptive statistics and paired/unpaired tests.

249 patients from 26 165 identified were analysed including 145 (58%) elective and 184 (74%) full colectomies. Number/cost of general practitioner consultations increased post-colectomy (p<0.001), and then decreased at 13-24 months (p<0.0ried according to the colectomy type. Ongoing and potentially unnecessary pharmacological therapy was seen in up to 30% of patients.
