We are pleased to share with you the 25 most downloaded Nature Communications articles* in health sciences published in 2022. (Please note we have a separate collection on the Top 25 COVID-19 papers.) Featuring authors from around the world, these papers highlight valuable research from an international community.
Here, the authors analyze the relation of fecal microbiota diversity and composition with depressive symptoms in 1,054 participants from the Rotterdam Study cohort and in 1,539 subjects of the Amsterdam HELIUS cohort, finding associations with bacteria known to be involved in the synthesis of key neurotransmitters for depression.
Heavy alcohol consumption has been associated with brain structural changes. Here, using data from the UK biobank, the authors report associations between alcohol intake and brain macrostructure and microstructure.
In a prospective longitudinal study of 833 adults, we demonstrate that how you wake up and regain alertness in the hours after sleep is weakly associated with your genes. Instead, the modifiable factors of how you are sleeping, eating and exercising influence your return to full alertness, free of sleepiness.
Understanding the emergence, evolution, and transmission of antibiotic resistance genes (ARGs) is essential to combat antimicrobial resistance. Here, Munk et al. analyse ARGs in hundreds of sewage samples from 101 countries and describe regional patterns, diverse genetic environments of common ARGs, and ARG-specific transmission patterns.
Sleep varies within and between individuals. Here, using self-reported sleep duration from a large sample of participants across 63 countries, the authors show three phases in the adult human life-course, consistent across culture, gender, education and other demographics.
Cancer-associated fibroblasts (CAFs) are a predominant and critical component of the tumour microenvironment. Here, the authors integrate and analyse single-cell RNA-seq data of CAFs across 10 common solid cancer types, identifying their plasticity and interactions with other cell types.
Here, Dekkers et al. characterize associations of 1528 gut metagenomic species with the plasma metabolome in 8583 participants of the SCAPIS Study, and find that gut microbiota explain up to 58% of the variance of individual plasma metabolites.
Federated ML (FL) provides an alternative to train accurate and generalizable ML models, by only sharing numerical model updates. Here, the authors present the largest FL study to-date to generate an automatic tumor boundary detector for glioblastoma.
Neuronal organoids derived from human induced pluripotent stem cells can be transplanted and integrated into the rodent cortex for the study of brain development and function. Here the authors demonstrate use of transparent graphene microelectrodes and two photon imaging for longitudinal, multimodal monitoring of functional connectivity between human iPSC derived neuronal organoids and the mouse cortex.
The authors record neural firing rates in a patient with ALS in completely locked-in state and show that the patient can modulate neural firing rates based on auditory feedback to select letters to form words and phrases to communicate his needs and experiences.
Animal studies have shown that pregnancy is associated with unique changes in the mammalian brain and behaviour, although pregnancy-associated changes in the human brain are less well studied. Here the authors show that pregnancy is associated with changes in resting state brain activity and brain anatomy which are most pronounced in the default mode network.
Lactic acid from glycolytic metabolism of cancer cells has been associated with immune suppressive functions. Here authors show that lactate, when depart from the acidic protons, inhibits histone deacetylases in CD8 + T cells, which turns them into potent anti-tumour immune cells.
The establishment and composition of the host microbiota is known to impact the function of the host immune response. Here the authors show that mode of delivery may impact the intestinal microbiota composition from birth and modulate the response to routine childhood vaccines.
Time-restricted eating, both early (eTRF) and mid-day (mTRF), have been shown to have metabolic benefits. Here the authors report a randomized controlled trial to compare the effects of eTRF and mTRF in healthy volunteers without obesity, and find that eTRF is more effective in improving the primary outcome insulin sensitivity.
Bacteriophage are natural antibiotic agents and provide natural building blocks for living biomaterials. Here, the authors crosslink self-organised bacteriophages to make sprayable microgels which preserves the natural antibacterial action, have tuneable auto-fluorescence and demonstrate application in food decontamination.
Circadian rhythms are known to impact a range of biological processes including in the immune system. Here the authors show how circadian rhythms modulate the T cell response to vaccination via regulation of dendritic cell metabolism.
Repair processes in kidney are impaired in severe disease. Here, the authors show that in kidney failure, genetic or pharmacologic inhibition of IL11 releases the brake on regeneration, reverses tissue damage and restores kidney function.
A number of human African trypanosomiasis, or sleeping sickness, patients suffer from respiratory symptoms commonly attributed to cardiac insufficiency. Here, the authors characterise the role of pulmonary Trypanosoma brucei in respiratory infection.
Early cancer detection by cell-free DNA (cfDNA) is challenged by the low amount of tumour DNA in cfDNA, tumour heterogeneity and the small patient cohorts. Here, the authors develop a method, cfMethyl-Seq, for cost-effective methylome profiling of cfDNA and for detecting and locating cancer.
Tumour microenvironment profiling during colorectal cancer progression may enable the discovery of therapeutic targets. Here, single cell and spatial RNA sequencing of tumour and adjacent normal tissues reveals an interaction between FAP+ fibroblasts and SPP1+ macrophages that could be disrupted as an immunotherapy strategy.
Detection of mutational signatures in cell-free DNA (cfDNA) is challenging due to low sequence coverage and low mutant allele fractions. Here, the authors identify mutational signatures in plasma whole genome sequencing of cancer patients and use machine learning to distinguish them from healthy individuals.
Predicting treatment response in cancer remains a highly complex task. Here, the authors develop Precily, a deep neural network framework to predict treatment response in cancer by considering gene expression, pathway activity estimates and drug features, and test this method in multiple datasets and preclinical models.
The role of the immune system in the pathogenesis of psychiatric disorders is unclear. Here, the authors show that genetic risk variants for multiple psychiatric disorders are enriched in regions of the genome active in the brain and in lymphoid cells, especially stimulated T cells, but not in myeloid cells.
Loss-of-function CRISPR-based screens have identified several genes associated with cancer resistance to T cell-induced cytotoxicity. Here the authors perform a genome-scale, gain-of-function CRISPR screen and identify candidate genes, including the poly-N-acetyllactosamine synthase B3GNT2, whose overexpression confers tumor cell resistance to T cell cytotoxicity
