Fidelity and coordination of mitochondrial protein synthesis in health and disease

The evolutionary acquisition of mitochondria has given rise to the diversity of eukaryotic life. Mitochondria have retained their ancestral α-proteobacterial traits through the maintenance of double membranes and their own circular genome. Their genome varies in size from very large in plants to the smallest in animals and their parasites. The mitochondrial genome encodes essential genes for protein synthesis and has to coordinate its expression with the nuclear genome from which it sources most of the proteins required for mitochondrial biogenesis and function.

Increasing incidence of invasive group A streptococcal disease in Western Australia, particularly among Indigenous people

The incidence of invasive GAS disease in WA increased between 2000 and 2018, particularly among Indigenous Australians. Mandatory notification of invasive GAS disease would therefore be appropriate. The social determinants of differences in incidence should be addressed, and other relevant host, pathogen, and health system factors investigated.

Mitochondrial mistranslation modulated by metabolic stress causes cardiovascular disease and reduced lifespan

Changes in the rate and fidelity of mitochondrial protein synthesis impact the metabolic and physiological roles of mitochondria. Here we explored how environmental stress in the form of a high-fat diet modulates mitochondrial translation and affects lifespan in mutant mice with error-prone or hyper-accurate mitochondrial ribosomes. Intriguingly, although both mutations are metabolically beneficial in reducing body weight, decreasing circulating insulin and increasing glucose tolerance during a high-fat diet, they manifest divergent (either deleterious or beneficial) outcomes in a tissue-specific manner.

Human erythroleukemia genetics and transcriptomes identify master transcription factors as functional disease drivers

Acute erythroleukemia (AEL or acute myeloid leukemia [AML]-M6) is a rare but aggressive hematologic malignancy. Previous studies showed that AEL leukemic cells often carry complex karyotypes and mutations in known AML-associated oncogenes.

Decreased Physical Working Capacity in Adolescents With Nonalcoholic Fatty Liver Disease Associates With Reduced Iron Availability

In a well-defined cohort of adolescents, we found non-alcoholic fatty liver disease to be associated with decreased cardiorespiratory fitness, independent of BMI

Clinical description and outcomes of Australian children with invasive group a streptococcal disease

Invasive group A streptococcal infection in Australian children is frequently severe and has a high long-term morbidity burden

Voices behind the statistics: A systematic literature review of the lived experience of rheumatic heart disease

This systematic review presents a critical, interpretive analysis of publications that include lived experiences of rheumatic heart disease

Priorities for improved management of acute rheumatic fever and rheumatic heart disease

The results suggest that timely injection and patient education are priorities for managing ARF and RHD, particularly focusing on child-to-adult transition care.

Qualitative study of psychosocial factors impacting on Aboriginal women's management of chronic disease

The caring roles and responsibilities Aboriginal women have in their community impact on their health

Standardizing clinical care measures of rheumatic heart disease in pregnancy: A qualitative synthesis

Pregnancy provides an opportunity to strengthen health system responses and address whole-of-life health for women with rheumatic heart disease
