A pioneering trial is giving mothers in poverty either a large or small cash gift each month for several years to find out whether a basic income changes a baby's brain and development

[Editorial] China's response to COVID-19: a chance for collaboration

The Lancet - Sa, 10/04/2021 - 00:00
April 8 marks a year since China's lifting of the 76-day lockdown in Wuhan—the epicentre of the COVID-19 outbreak. Since the reopening of Wuhan, efforts to control the pandemic in China have thus far successfully prevented resurgence and importation of new cases, while re-establishing the country's social and economic activities. Although China has since had sporadic outbreaks of COVID-19 in several areas, including Beijing and Qingdao, they were all contained. How has China managed to control COVID-19? And is the global scientific community in a position to benefit from China's experiences?

[Comment] Newer versus older antiseizure medications: further forward?

The Lancet - Sa, 10/04/2021 - 00:00
Since 1990, many new antiseizure medications have been launched. Many have been licensed on the basis of evidence from add-on therapy in resistant epilepsies; there have been few head-to-head comparative data in patients who are newly diagnosed.1 Findings from Standard and New Antiepileptic Drugs (SANAD) I, the first SANAD trial, provided the first comprehensive data to address this question; lamotrigine was shown to be superior to carbamazepine, gabapentin, oxcarbazepine, and topiramate in time to treatment failure,2 and valproate was a clinically and cost-effective alternative to lamotrigine or topiramate.

[Perspectives] Donna Kinnair: campaigning for the real value of nursing

The Lancet - Sa, 10/04/2021 - 00:00
Nursing had always been a career that Professor Dame Donna Kinnair, Chief Executive and General Secretary of the UK Royal College of Nursing (RCN) and Non-Executive Director, East London NHS Foundation Trust, wanted to be a part of. Her family came to the UK in the 1950s, part of the Windrush generation. “I have a brother who is a doctor, and a sister who is a midwife…nursing was actually a part of my family, it was also part of my family history in the Caribbean”, she says. Yet nursing wasn't the path she initially followed.

[Perspectives] The CRISPR wars

The Lancet - Sa, 10/04/2021 - 00:00
The 2020 Nobel Prize in Chemistry was one of the least surprising in recent times. No Nobel watchers doubted that it would be awarded soon for the discovery of the CRISPR-Cas9 system of genome editing that has transformed the technologies and possibilities of genetic manipulation. The uncertainty, however, was about who would get it. Few questioned that biochemist Jennifer Doudna of the University of California, Berkeley, and microbiologist Emmanuelle Charpentier of the Max Planck Unit for the Science of Pathogens (who did some of the key work while at Umeå University, Sweden) were the leading candidates.

[Perspectives] Racism is the public health crisis

The Lancet - Sa, 10/04/2021 - 00:00
The US police killings of Breonna Taylor and George Floyd in 2020 sparked a set of responses and uprisings to racism that may have seemed different but should by now be all too familiar. Huge numbers of people protested, institutions made all the right noises, and there have been increased book sales for Black authors. The sheer size of the protests and the commitments from governments and corporations to make lasting changes have led to renewed optimism that this time it may be different. Yet there are persisting, major deficits in our collective education about racism and protest.

[Articles] The SANAD II study of the effectiveness and cost-effectiveness of levetiracetam, zonisamide, or lamotrigine for newly diagnosed focal epilepsy: an open-label, non-inferiority, multicentre, phase 4, randomised controlled trial

The Lancet - Sa, 10/04/2021 - 00:00
These findings do not support the use of levetiracetam or zonisamide as first-line treatments for patients with focal epilepsy. Lamotrigine should remain a first-line treatment for patients with focal epilepsy and should be the standard treatment in future trials.

The Lancet - Sa, 10/04/2021 - 00:00
Compared with valproate, levetiracetam was found to be neither clinically effective nor cost-effective. For girls and women of child-bearing potential, these results inform discussions about benefit and harm of avoiding valproate.
