m versus 391 h in the non-algorithm group. The percentage of seizure hours correctly identified was higher in the algorithm group than in the non-algorithm group (177 [66·0%; 95% CI 53·8-77·3] of 268 h vs 177 [45·3%; 34·5-58·3] of 391 h; difference 20·8% [3·6-37·1]). No significant differences were seen in the percentage of neonates with seizures given at least one inappropriate antiseizure medication (37·5% [95% CI 25·0 to 56·3] vs 31·6% [21·1 to 47·4]; difference 5·9% [-14·0 to 26·3]).

ANSeR, a machine-learning algorithm, is safe and able to accurately detect neonatal seizures. Although the algorithm did not enhance identification of individual neonates with seizures beyond conventional EEG, recognition of seizure hours was improved with use of ANSeR. The benefit might be greater in less experienced centres, but further study is required.

Early implementation outcomes often suggest poor PrEP adherence and persistence; however, this intervention is time-limited and the need for PrEP fluctuates as risk behaviours change. In this Viewpoint we examine the current guidelines and early programmatic outcomes after starting, stopping, and restarting PrEP, and we review the implications of PrEP in relation to HIV testing algorithms. Guidelines suggest to discontinue PrEP when a person is no longer at risk for HIV, but effectively implementing this strategy requires support tools to make the decision of stopping and restarting PrEP that considers the complex relationship between risk perceptions and risk behaviours. Exarafenib Safely discontinuing PrEP also requires greater understanding of the daily dosing duration that is needed to protect the person after their last HIV exposure. Additionally, clear strategies are needed to re-engage a person as their HIV exposure risk changes over time.The safety and efficacy of anti-diabetic drugs are critical for maximizing the beneficial impacts of well-controlled blood glucose on the prognosis of individuals with COVID-19 and pre-existing type 2 diabetes (T2D). Metformin is the most commonly prescribed first-line medication for T2D, but its impact on the outcomes of individuals with COVID-19 and T2D remains to be clarified. Our current retrospective study in a cohort of 1,213 hospitalized individuals with COVID-19 and pre-existing T2D indicated that metformin use was significantly associated with a higher incidence of acidosis, particularly in cases with severe COVID-19, but not with 28-day COVID-19-related mortality. Furthermore, metformin use was significantly associated with reduced heart failure and inflammation. Our findings provide clinical evidence in support of continuing metformin treatment in individuals with COVID-19 and pre-existing T2D, but acidosis and kidney function should be carefully monitored in individuals with severe COVID-19.The COVID-19 pandemic and the World War 2 aerial bombing campaign against the UK between 1939 and 1945 both exposed the civilian population to a sustained threat. Risk, whether from exposure to viral load or the density of the bombing, led to a range of protective measures and behavioural regulations being implemented. The V1 and V2 missiles used in summer and autumn, 1944, functioned as a second wave of bombing, arriving after people believed the danger had passed. Adherence to lockdown and a reluctance to return to work after the lifting of lockdown during the COVID-19 pandemic in the UK were mirrored in the preference for using home-based bomb shelters during the air raids. Heightened sensitivity to risk, or a so-called deep shelter mentality, did not materialise even during the second wave of bomb attacks and some deep bomb shelters were closed because of low occupancy. The most popular protective measures were those that reflected people’s preferences, and not necessarily those that provided the greatest safety. As with the COVID-19 pandemic, the public drove government policy as much as they followed it.The phenomenon of a gene expression burst has been attributed to random transitions between the active and inactive states of a gene. However, the mechanisms underlying regulation of the activation process in response to environmental changes remain unclear. Here, we model gene activation as a consequence of the competitive cross talk between a weak basal pathway and an inducible signaling pathway and reveal rich expression dynamics along with intricate dependence of noise and Fano factor on mean expression levels. These theoretical results are in good agreement with a large experimental data set in Escherichia coli, yeast, and mammalian cells. Furthermore, both theoretical analyses and supporting biological evidence converge to demonstrate the existence of a tradeoff that governs the sharp up- and downregulation of gene expression, suggesting an ordered scenario that activates a gene under varying conditions. These regulation modes, together with cross talk pathways, may provide new guidance for the analysis and interpretation of genetic data in various applications, ranging from genetic engineering to therapeutic targets of disease.Polio is a deadly viral disease that has been paralyzing many children in Afghanistan. Despite fundamental efforts, primarily vaccination, to reduce the number of cases in Afghanistan, there are still many children who are deprived of the vaccine every year. Afghanistan is one of the two remaining countries endemic for polio, and the country has undergone various challenges that have hampered the eradication of this disease. The underlying challenges include inaccessibility of unsecured areas, illiteracy, refusal, and, most recently, COVID-19. The country is in the midst of a battle against COVID-19, and polio has almost entirely been neglected. Sadly, polio cases are increasing in the country, particularly in polio-free provinces. After an initial lockdown, many businesses have been allowed to resume, but the mass polio vaccination campaign has not restarted. New cases of polio will surge if endemic regions remain unvaccinated or inaccessible. To curb the further spread of polio, Afghanistan needs to resume nationwide house-to-house vaccination as restrictions due to COVID-19 are loosened.
