  • Reducing energy intake is known to result in weight loss. However, there is a need for real-world data on the impact of specific interventions to reduce energy intake. A recent trial in PLOS Medicine evaluated whether reductions in portion size and in the availability of high energy foods in workplace cafeterias could reduce energy consumption.

  • Dalle Carbonare et al. perform a serology study in participants with a prior infection of SARS-CoV-2 and those who are SARS-CoV-2-naïve, who received two doses of the Pfizer-BioNTech BNT162b2 vaccine. After a single dose they observe a quicker recall of pseudovirus neutralization titres in previously-infected participants and a potent IgA response in both groups that was not associated with serum neutralization titres.

  • Plontke et al. report data on the preservation of vestibular function in a series of patients undergoing surgical removal of intracochlear tumors. Using objective clinical tests, the authors show that in most patients the vestibular system can function normally despite major surgical trauma to the cochlea.

  • Bast et al. discuss the early detection of ovarian cancer in the context of the recent UKCTOCS screening trial. The authors suggest potential reasons why the trial failed to achieve a reduction in mortality and outline next steps in the development of biomarkers and imaging modalities to detect ovarian cancer.

  • Ying et al. conduct a multi-instrument Mendelian randomization study looking at the link between aging and COVID-19 risk. They observe an association between genetic variation implicated in longevity and decreased risk of COVID-19 infection and hospitalization, with Notch signaling and immune system development loci found to be important in aging-related COVID-19 risk.

  • Regenerative medicine may offer strategies to alleviate the debilitating symptoms of osteoarthritis and delay the time to joint replacement. In a study now published in Science Translational Medicine, Acevedo Rua and colleagues provide evidence of the therapeutic potential of autologous nasal chondrocyte-derived cartilage grafts in repairing arthritis-damaged knee joints.

  • Wong and Ngan et al. characterize the expression and structural variation of SARS-CoV-2 subgenomic RNAs (sgRNAs) in diagnostic specimens from symptomatic and asymptomatic COVID-19 patients. In a series of genomic and transcriptomic analyses, the authors observe reduced sgRNA expression and a distinct set of structural deletions in asymptomatic infections compared with symptomatic infections.

  • Levi and Ubaldi et al. evaluate SARS-CoV-2 seroprevalence in a cohort of 4735 healthcare workers in northern Italy. In seropositive individuals, they show that antibodies are maintained over a period of 8 to 10 months and associate changes in antibody levels over this period with symptoms and specific subgroups of participants.
