De novo birth of functional microproteins in the human lineage.

Small open reading frames (sORFs) can encode functional "microproteins" that perform crucial biological tasks. However, their size makes them less amenable to genomic analysis, and their origins and conservation are poorly understood. Given their short length, it is plausible that some of these functional microproteins have recently originated entirely de novo from noncoding sequences. Here we sought to identify such cases in the human lineage by reconstructing the evolutionary origins of human microproteins previously found to have measurable, statistically significant fitness effects. By tracing the formation of each ORF and its transcriptional activation, we show that novel microproteins with significant phenotypic effects have emerged de novo throughout animal evolution, including two after the human-chimpanzee split. Notably, traditional methods for assessing coding potential would miss most of these cases. This evidence demonstrates that the functional potential intrinsic to sORFs can be relatively rapidly and frequently realized through de novo gene emergence.

Genomics-informed outbreak investigations of SARS-CoV-2 using civet.

The scale of data produced during the SARS-CoV-2 pandemic has been unprecedented, with more than 13 million sequences shared publicly at the time of writing. This wealth of sequence data provides important context for interpreting local outbreaks. However, placing sequences of interest into national and international context is difficult given the size of the global dataset. Often outbreak investigations and genomic surveillance efforts require running similar analyses again and again on the latest dataset and producing reports. We developed civet (cluster investigation and virus epidemiology tool) to aid these routine analyses and facilitate virus outbreak investigation and surveillance. Civet can place sequences of interest in the local context of background diversity, resolving the query into different 'catchments' and presenting the phylogenetic results alongside metadata in an interactive, distributable report. Civet can be used on a fine scale for clinical outbreak investigation, for local surveillance and cluster discovery, and to routinely summarise the virus diversity circulating on a national level. Civet reports have helped researchers and public health bodies feedback genomic information in the appropriate context within a timeframe that is useful for public health.

Treatment of infertility with hypogonadotropic hypogonadism: 10-year experience in Auckland, New Zealand.

Infertility in idiopathic or acquired hypogonadotropic hypogonadism (HH) was managed with exogenous gonadotropins and artificial reproduction as needed, in Auckland, New Zealand, from 2000 to 2010. Of eight men seeking conception, 2/2 with acquired HH but only 2/6 with congenital HH achieved clinical pregnancy with exogenous gonadotropins, whereas 12/14 women (86%) achieved one or more live births. Current gonadotropin treatment does not seem to be optimal for men with congenital HH.

Health equity: what does it mean for child health?

The concept of 'health equity' has become increasingly central to discussions around social determinants of health, and the resultant disparities in health outcomes. It has particular pertinence to paediatric populations in New Zealand: some of our most alarming disparities relate to child health, and there is increasing recognition of the need to reduce these inequities. Effective 'health equity' approaches in child health demand that clinicians broaden their roles to become strong advocates for social justice: in order to achieve progress in this area, it is essential that child health is prioritised at our most fundamental policy levels.
