Attributes and predictors of long COVID

Reports of long-lasting coronavirus disease 2019 (COVID-19) symptoms, the so-called ‘long COVID’, are rising but little is known about prevalence, risk factors or whether it is possible to predict a protracted course early in the disease. 

We analyzed data from 4,182 incident cases of COVID-19 in which individuals self-reported their symptoms prospectively in the COVID Symptom Study app¹. 

A total of 558 (13.3%) participants reported symptoms lasting ≥28 days, 189 (4.5%) for ≥8 weeks and 95 (2.3%) for ≥12 weeks. Long COVID was characterized by symptoms of fatigue, headache, dyspnea and anosmia and was more likely with increasing age and body mass index and female sex. 

Experiencing more than five symptoms during the first week of illness was associated with long COVID (odds ratio = 3.53 (2.76–4.50)). A simple model to distinguish between short COVID and long COVID at 7 days (total sample size, n = 2,149) showed an area under the curve of the receiver operating characteristic curve of 76%, with replication in an independent sample of 2,472 individuals who were positive for severe acute respiratory syndrome coronavirus 2. 

This model could be used to identify individuals at risk of long COVID for trials of prevention or treatment and to plan education and rehabilitation services.

Highly foldable, robust and water-resistant cellulose specialty paper reinforced by aramid nanofibers

Mechanical strength and water resistance are typical issues with cellulose paper due to the nature of cellulose. 

Specialty papers that are highly foldable, such as banknotes and securities, must be able to withstand multiple folding actions while also providing exceptional durability. 

In this paper, a multi-approach strategy involving direct addition, in-situ growth, and coating is proposed for introducing aramid nanofibers (ANFs) as 1D nanofillers and 2D membranes to improve the overall properties of cellulose specialty paper. 

The flexible and fatigue-resistant ANFs with a large aspect ratio play the roles of filling and bridging between cellulose fibers and ANF via massive hydrogen bonds. 

The resulting 1.5 wt% ANF reinforced paper has a tensile index of 79.1 N m/g, an impressive folding endurance of over 3500 times, and strong water resistance (a water contact angle of 85.2°). 

Furthermore, SEM observation of paper during various folding periods reveals that the filling and bridging effects of ANFs, as well as their highly entangled nanofibrous network, contribute to paper's excellent foldability. 

This work facilitates promising candidates for simultaneously achieving robust, highly foldable, durable and water-resistant cellulose specialty paper.
