Early childhood education staff are falling through a vaccination policy gap in New Zealand.

N Z Med J 2022 Jan 21;135(1548):96-102. Epub 2022 Jan 21.

Office of Early Childhood Education.

The recent COVID-19 vaccine mandate among early childhood education (ECE) staff highlights the important role ECE staff have in the transmission of infectious diseases. However, there are no data on general vaccine uptake for this group in New Zealand. Additionally, the importance of ECE staff vaccination as a strategy to prevent illness has been rarely promoted in the past, and recommendations for other vaccinations in this group are lacking.

Precancerous cervical lesions caused by non-vaccine-preventable HPV types after vaccination with the bivalent AS04-adjuvanted HPV vaccine: an analysis of the long-term follow-up study from the randomised Costa Rica HPV Vaccine Trial.

Lancet Oncol 2022 Jun 13. Epub 2022 Jun 13.

Division of Cancer Epidemiology and Genetics, National Cancer Institute, National Institutes of Health, Bethesda, MD, USA.

Background: In women vaccinated against human papillomavirus (HPV), reductions in cervical disease and related procedures results in more women having intact transformation zones, potentially increasing the risk of cervical lesions caused by non-vaccine-preventable HPV types, a phenomenon termed clinical unmasking. We aimed to evaluate HPV vaccine efficacy against cervical intraepithelial neoplasia grade 2 or worse (CIN2+) and cervical intraepithelial neoplasia grade 3 or worse (CIN3+) attributed to non-preventable HPV types in the long-term follow-up phase of the Costa Rica HPV Vaccine Trial (CVT).

Methods: CVT was a randomised, double-blind, community-based trial done in Costa Rica. Read More

Oncolytic virus expressing PD-1 inhibitors activates a collaborative intratumoral immune response to control tumor and synergizes with CTLA-4 or TIM-3 blockade.

J Immunother Cancer 2022 Jun;10(6)

State Key Laboratory of Molecular Vaccinology and Molecular Diagnostics, National Institute of Diagnostics and Vaccine Development in Infectious Diseases, School of Public Health, Xiamen University, Xiamen, Fujian, China

Background: Oncolytic viruses (OVs) are capable to inflame the tumor microenvironment (TME) and elicit infiltrating tumor-specific T cell responses. However, OV treatment negatively alters the cancer-immune set point in tumors to attenuate the antitumor immune response, which suggests the necessity of dissecting the immune landscape of the virus-treated tumors and developing novel strategies to maximize the potential of OVs. The aim of this study is to investigate the effect of the single-chain variable fragment (scFv)-armed OVs targeting PD-1 on the TME, and ultimately overcome localized immunosuppression to sensitize tumors to immunotherapies.

Preservation of Anti-cytomegalovirus Activity in Human Milk Following High-Pressure Processing Compared to Holder Pasteurization.

Front Nutr 2022 19;9:918814. Epub 2022 May 19.

Translational Medicine Program, Research Institute, The Hospital for Sick Children, Toronto, ON, Canada.

Pasteurized donor human milk is recommended for hospitalized preterm infants when mother's own milk is unavailable. Our aim was to compare the antiviral activity of human milk processed by Holder pasteurization (HoP) or high-pressure processing (HPP) against representative enveloped and non-enveloped viruses including cytomegalovirus and hepatitis A virus. Expressed milk from 20 donors collected from the Ontario Milk Bank was combined into 10 pools, each from two unique donors. Read More

Associations of different immune checkpoints-expressing CD4 Treg/ T cell subsets with disease-free survival in colorectal cancer patients.

BMC Cancer 2022 Jun 2;22(1):601. Epub 2022 Jun 2.

Natural and Medical Sciences Research Center, University of Nizwa, P.O. Box 33, Nizwa, 616, Oman.

There are different subsets of T regulatory cells (Tregs), orchestrating critical roles in the regulation of anti-tumor immunity in colorectal cancer (CRC). In this study, we report that a high frequency of circulating CD4FoxP3 Tregs was associated with poorer disease-free survival (DFS), while their higher frequencies in tumor-infiltrating CD4 Tregs was associated with better DFS. We further investigated such associations with four Tregs/T cells expressing or lacking FoxP3 and Helios (FoxP3Helios). Read More

[The investigation on the acute, severe hepatitis of unknown origin in children].

Zhongguo Dang Dai Er Ke Za Zhi 2022 Jun;24(6):604-613

National Center for Children's Health/Beijing Children's Hospital, Capital Medical University/Laboratory of Microbiology, Beijing Pediatric Research Institute/National Key Discipline of Pediatrics (Capital Medical University)/Key Laboratory of Major Diseases in Children, Ministry of Education, Beijing 100045, China.

In April 2022, the United Kingdom notified the World Health Organization (WHO) of an unexpected increase of acute hepatitis of unknown origin in children. Subsequent investigations have found more than 400 cases in more than 20 countries and regions around the world. Although the potential role of adenovirus type 41 in the pathogenesis of these cases is one hypothesis, but it is probably not the only pathogenic factor, and other infectious and non-infectious causes cannot be completely ruled out.

Analysis of non-severe acute onset autoimmune hepatitis according to the presence of radiological heterogeneity.

Hepatol Res 2022 May 31. Epub 2022 May 31.

Department of Gastroenterology, Graduate School of Medicine, Chiba University, Chiba, Japan.

Aim: Diagnosis of acute onset autoimmune hepatitis (A-AIH) has been difficult in that patients may not have typical clinicopathological features of AIH. In our previous reports of severe and fulminant AIH, two-thirds of them showed radiological heterogeneity: hepatic heterogeneous hypoattenuation on unenhanced computed tomography (CT) reflecting heterogeneous distribution of massive hepatic necrosis (severe centrilobular necrosis), which would be beneficial for the diagnosis. In the present study, we analyzed non-severe A-AIH patients with or without radiological heterogeneity and tried to find novel clinical features for supporting the early diagnosis. Read More

Gastroenterology, Hepatology and Nutrition, The Ohio State Wexner Medical Center, Columbus, OH, USA.

Objectives: Predictors of negative outcomes related to hepatitis A virus (HAV) need to be studied at a national level.
