Sun-immune connection

Exposure to ultraviolet radiation damages skin cell DNA but skin cancers develop because ultraviolet radiation also affects the immune system

Availability and administration of benzathine penicillin G for the prevention of rheumatic fever in Africa: Report of the Working Group on Penicillin

Benzathine penicillin G availability should be addressed and African health workers’ knowledge and practices need to be augmented

Paediatric asylum seekers in Western Australia: Identification of adversity and complex needs through comprehensive refugee health assessment

Paediatric asylum seekers have complex trauma backgrounds with exposure to multiple adverse events within disrupted family units

An assessment of computer-generated stimuli for use in studies of body size estimation and bias

Our results show that perception of body size for computer-generated stimuli was non-linear

Corynebacterium and Dolosigranulum: Future probiotic candidates for upper respiratory tract infections

We recently identified C. pseudodiphtheriticum and D. pigrum as the major nasopharyngeal species associated with resistance to recurrent ear infections

Biogeography of the Relationship between the Child Gut Microbiome and Innate Immune System

The gut microbiome is a well-recognized modulator of host immunity, and its compositions differ between geographically separated human populations. Systemic innate immune responses to microbial derivatives also differ between geographically distinct human populations. However, the potential role of the microbiome in mediating geographically varied immune responses is unexplored. We here applied 16S amplicon sequencing to profile the stool microbiome and, in parallel, measured whole-blood innate immune cytokine responses to several pattern recognition receptor (PRR) agonists among 2-year-old children across biogeographically diverse settings. Microbiomes differed mainly between high- and low-resource environments and were not strongly associated with other demographic factors. We found strong correlations between responses to Toll-like receptor 2 (TLR2) and relative abundances of Bacteroides and Prevotella populations, shared among Canadian and Ecuadorean children.

Global phosphoproteomics reveals DYRK1A regulates CDK1 activity in glioblastoma cells

Both tumour suppressive and oncogenic functions have been reported for dual-specificity tyrosine phosphorylation-regulated kinase 1A (DYRK1A). Herein, we performed a detailed investigation to delineate the role of DYRK1A in glioblastoma. Our phosphoproteomic and mechanistic studies show that DYRK1A induces degradation of cyclin B by phosphorylating CDC23, which is necessary for the function of the anaphase-promoting complex, a ubiquitin ligase that degrades mitotic proteins.

Weather and children's time allocation

This paper presents the first causal estimates of the effect of weather on children's time allocation. It exploits exogenous variations in local weather observed during the random diary dates of two nationally representative cohorts of Australian children whose time-use diaries were surveyed biennially over 10 years.

Clinical Implications of Minimal Residual Disease Detection in Infants With KMT2A-Rearranged Acute Lymphoblastic Leukemia Treated on the Interfant-06 Protocol

Infant acute lymphoblastic leukemia (ALL) is characterized by a high incidence of KMT2A gene rearrangements and poor outcome. We evaluated the value of minimal residual disease (MRD) in infants with KMT2A-rearranged ALL treated within the Interfant-06 protocol, which compared lymphoid-style consolidation (protocol IB) versus myeloid-style consolidation (araC, daunorubicin, etoposide/mitoxantrone, araC, etoposide).

Gender Balance in Anesthesiology: Is a Change of Societal Mindset Needed?

With great interest, we are following the discussion on Speaker Gender Representation and Trends in Authorship. While it is indeed very popular and important to look at speaker representation, authorship, or board membership by gender, the underlying reasons for the unequal gender representation are not as easy to determine. Counting numbers on panels or boards may also not add up to real representation.
