Abstract Preterm birth (PTB) is the leading cause of infant mortality worldwide. Changes in PTB rates, ranging from −90% to +30%, were reported many countries following early COVID-19 pandemic response measures (‘lockdowns’). It unclear whether this variation reflects real differences lockdown impacts, or perhaps stillbirth rates and/or study designs. Here we present interrupted time series and meta-analyses using harmonized data 52 million births 26 countries, 18 which had representative...

A surficial geology and geomorphology map of the forelands Sandfellsjökull Oldufellsjökull piedmont lobes east Mýrdalsjökull ice cap is used to characterise historical modern landscape imprint in a glacial landsystems context. This serves as analogue for palaeoglaciological reconstructions systems that operated outlet contrasting dynamics, but subtle variability process-form regimes encoded geomorphology. The two reflect significantly different regimes, hence glacier despite fact they are...
