This analysis of 2-year retrospective cohort studies of individuals diagnosed with COVID-19 showed that the increased incidence of mood and anxiety disorders was transient, with no overall excess of these diagnoses compared with other respiratory infections. In contrast, the increased risk of psychotic disorder, cognitive deficit, dementia, and epilepsy or seizures persisted throughout. The differing trajectories suggest a different pathogenesis for these outcomes. Children have a more benign overall profile of psychiatric risk than do adults and older adults, but their sustained higher risk of some diagnoses is of concern. The fact that neurological and psychiatric outcomes were similar during the delta and omicron waves indicates that the burden on the health-care system might continue even with variants that are less severe in other respects. Our findings are relevant to understanding individual-level and population-level risks of neurological and psychiatric disorders after SARS-CoV-2 infection and can help inform our responses to them.

A proportion of patients experience long-lasting symptoms in the weeks and months after a diagnosis of COVID-19. 1–3 Of those symptoms, cognitive impairment (also referred to as ‘brain fog’) is particularly worrisome: it is one of the most common, 4, 5 can affect those with even relatively mild acute COVID-19 illness 1, 5 and results in the inability to work for many affected patients. 3 While emerging research is starting to characterize the clinical presentation of post-COVID cognitive deficits, 6 its pathogenesis remains elusive. Identifying therapeutic targets is critical to reducing the burden of this COVID-19 complication.

Endotheliopathy has been hypothesized as one potential mechanism underlying post-COVID cognitive deficits. 7 According to recent research, microvascular brain pathology following COVID-19 can be caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) main protease Mpro cleaving nuclear factor-κB essential modulator thus inducing the death of brain endothelial cells. 8 The same study showed that pharmacologically inhibiting receptor-interacting protein kinase (RIPK) signaling prevents the Mpro-induced microvascular pathology. 8

This research leads to the following hypothesis: exposure to a pharmacological inhibitor of RIPK signaling at the time of COVID-19 infection reduces the risk of post-COVID cognitive deficits. In this study, we tested this hypothesis using a retrospective cohort study based on electronic health records (EHRs) data. While many pharmacological agents inhibit RIPK signaling, 9 most are only used in very rare clinical scenarios (e.g. sunitinib for the treatment of advanced renal cell carcinoma or pancreatic neuroendocrine tumors). The exception is phenytoin which is used as an anti-epileptic drug and which, among its other effects, is a RIPK1 inhibitor protecting against necroptosis. 10, 11 In this study, we compared the incidence of post-COVID cognitive deficits between patients exposed to phenytoin and matched cohorts of patients exposed to other anti-epileptic drugs at the time of their COVID-19 diagnosis.

There’s an epidemic in Western countries, and one few people are aware of. It’s an epidemic of visceral fat, a deep kind of fat that packs around vital organs, like the liver, and is linked with health problems like diabetes, heart disease, and high blood pressure.

You might assume that only people who are overweight or obese have too much visceral fat, but that’s not the case. Thin people, particularly inactive ones and older individuals, can have enough visceral fat to increase their risk of chronic health problems. They may look thin, but they’re not healthy because they have too much visceral fat and other markers of bad health.

Although it’s not easy to trim down visceral fat, science shows there are ways to reduce your body’s visceral fat burden and improve your health simultaneously.

Increased demand for super tiny electronic sensors coming from healthcare, environmental services and the Internet of Things is prompting a search for equally tiny ways to power these sensors. A review of the state of ultracompact supercapacitors, or “micro-supercapacitors,” concludes there is still a lot of research to be done before these devices can deliver on their promise.

The review appeared in the journal Nano Research Energy.

The explosion of demand in recent years for miniaturized , such as health monitors, environmental sensors and wireless communications technologies has in turn driven demand for components for those devices that have ever smaller size and weight, with lower energy consumption, and all of this at cheaper prices.

An algorithm developed by researchers from Helmholtz Munich, the Technical University of Munich (TUM) and its University Hospital rechts der Isar, the University Hospital Bonn (UKB) and the University of Bonn is able to learn independently across different medical institutions. The key feature is that it is self-learning, meaning it does not require extensive, time-consuming findings or markings by radiologists in the MRI images.

This federated was trained on more than 1,500 MRI scans of healthy study participants from four institutions while maintaining data privacy. The algorithm then was used to analyze more than 500 patient MRI scans to detect diseases such as multiple sclerosis, vascular disease, and various forms of brain tumors that the algorithm had never seen before. This opens up new possibilities for developing efficient AI-based federated algorithms that learn autonomously while protecting privacy. The study has now been published in the journal Nature Machine Intelligence.

Health care is currently being revolutionized by artificial intelligence. With precise AI solutions, doctors can be supported in diagnosis. However, such algorithms require a considerable amount of data and the associated radiological specialist findings for training. The creation of such a large, central database, however, places special demands on . Additionally, the creation of the findings and annotations, for example the marking of tumors in an MRI image, is very time-consuming.

According to recent Baycrest research, adults without dementia risk factors like smoking, diabetes, or hearing loss had brain health comparable to that of those who are 10 to 20 years younger than them. According to the research, only one dementia risk factor can age a person’s cognition by up to three years.

“Our results suggest lifestyle factors may be more important than age in determining someone’s level of cognitive functioning. This is great news since there’s a lot you can do to modify these factors, such as managing diabetes, addressing hearing loss, and getting the support you need to quit smoking,” says Dr. Annalise LaPlume, Postdoctoral Fellow at Baycrest’s Rotman Research Institute (RRI) and the study’s lead author.

The research is one of the first to look at lifestyle risk factors for dementia across the entire lifespan.

In a significant development, Massachusetts Institute of Technology (MIT) engineers have developed a new category of wireless wearable skin-like sensors for health monitoring that doesn’t require batteries or an internal processor.

The team’s sensor design is a form of electronic skin, or “e-skin” — a flexible, semiconducting film that conforms to the skin like electronic Scotch tape, according to a press release published by MIT.

“If there is any change in the pulse, or chemicals in sweat, or even ultraviolet exposure to skin, all of this activity can change the pattern of surface acoustic waves on the gallium nitride film,” said Yeongin Kim, study’s first author, and a former MIT postdoc scholar.
