A team of scientists from Durham University has uncovered surprising insights into the behaviour of wild baboons in South Africa using an innovative camera collar system.

The findings, published in the International Journal of Primatology, provide an unprecedented baboon’s-eye view of their eating habits and interactions with other species.

Researchers have discovered that baboons are much more opportunistic foragers than they realised.

The collar cameras allowed the researchers to literally see what a baboon sees - and they were eating antelope faeces.

The collar cameras recorded footage showing baboons carefully selecting and consuming the faeces from antelope species like kudu, impala and duiker.

Researchers suggest that they might gain nutrients from the faeces when food is scarce.

The cameras also revealed close encounters between baboons and unhabituated wildlife like banded mongooses, impala and nyala.

These animals would have fled if the data had been collected by human observation, a more traditional method of studying primate behaviour.

This pioneering study highlights how collar-cameras can uncover the intricate, unseen lives of wild primates for science and conservation.

Lead researcher of the study, Ben Walton of Durham University said: “Seeing the world through the eyes of these primates gave us unparalleled insight into their daily lives, including what they eat and how they interact with each other and other species.

“It has been exciting to explore the ways in which cameras such as these could improve our understanding of primate behaviour in future.”

Commenting on the findings, study co-author Professor Russell Hill of Durham University said: “Baboons are amongst the best studied primates.

“To uncover undocumented foraging behaviour in just a few days using these collar cameras was thus really surprising.

“I have been studying baboons for years, but this primate’s eye view gave me a totally different perspective on their behaviour.”

Researchers point out that this method has amazing potential to engage the public in research and the footage from these cameras was used in the BBC Natural History Unit documentary: Animals with Cameras.

The team developed the prototype collar cameras with the BBC Natural History Unit for the TV series Animals with Cameras.

They believe the technology has huge potential for primate research on activity budgets, diet, social dynamics and more.

Researchers can study predator-prey interactions and social behaviour in a completely natural, unbiased way.

Mystery of unexplained kidney disease revealed to patients

Peer-Reviewed Publication

NEWCASTLE UNIVERSITY

Scientists have identified a new method of analysing genomic data in a major discovery that means patients with unexplained kidney failure are finally getting a diagnosis.

Experts at Newcastle University have worked with data from Genomics England 100,000 Genomes project to establish a diagnosis in patients with unexplained kidney failure.

There are numerous reasons for kidney failure, which if left untreated is life-threatening, but often patients do not get a precise diagnosis which can make their best course of treatment unclear.

Missing genetic data

Research, published in the Genetics in Medicine Open, has now revealed that for these patients areas in their genome are missing so are not detected as faulty when using the routine genetic pipelines to analyse data. 

Scientists say that as this missing gene has now been identified, and mutations within it found, they have been able to classify this as NPHP1-related kidney failure.

Professor John Sayer, Deputy Dean of Biosciences at Newcastle University, said: “Our new genomic methods and their results has huge implications for the patients and families with kidney failure who were previously genetically unsolved.

“What we are now able to do is give some patients a precise diagnosis, which allows their investigations, treatment and management to be tailored to their needs for the best possible outcomes.”

In the study, experts reviewed genetic sequencing data from 959 patients with advanced kidney disease, where a total of 11 patients were identified as having a deleted region genome, leading to a complete loss of a kidney gene and this had previously been undetectable.

The new approach was also used to examine genomic data from 11,754 cases to make new genetic diagnoses of 10 other UK patients with unexplained deafness and blindness, again who had previously been genetically unexplained.

Professor Sayer, who is also a consultant nephrologist at Newcastle upon Tyne Hospitals NHS Foundation Trust, added: “We knew that many of our unsolved cases had a genetic disorder, and this new approach enables us to solve these cases definitively.

“We can now give an accurate genetic diagnosis to many more families affected by kidney disease and our hope is to provide a proper diagnosis for many more families in the future.

“This work is a reminder that it is always worth investigating the underlying reasons for kidney failure to get to the bottom of the condition.

“Finding a genetic cause of kidney failure has huge implications for the patient and also for other family members, especially if they are wishing to donate a kidney to their loved one.”

The work, co-funded by Kidney Research UK and the Northern Counties Kidney Research Fund, was possible through the Genomics England 100,000 Genomes project, where Professor Sayer has been instrumental in the North East’s success of this project.

The Newcastle experts are now working with cell lines taken from patients to study more in detail the disease process and to test potential treatments.

Newcastle University and Newcastle Hospitals are both part of Newcastle Health Innovation Partners (NHIP). NHIP is one of eight prestigious Academic Health Science Centres (AHSCs) across the UK, bringing together partners to deliver excellence in research, health education and patient care.

Case study: Family finally given answers

The Bingham family have three members all affected by kidney disease.

Siblings Noah, 23, and Ariel, 19, have both had kidney transplants and their younger brother, Casper, 15, has been diagnosed with kidney disease.

The family, from Hexham, Northumberland, are part of the Genomics England 100,000 Genomes project and were one of the families identified as having the gene deletion, NPHP1-related kidney failure.

Noah presented with kidney failure just after finishing his A-levels and, at the same time, Ariel was being treated for reduced kidney function.

Both now have donated kidneys as their own organs function reduced to dangerously low levels. Sadly, Noah’s transplanted kidney failed after only 16 months, and he had to start haemodialysis again in February this year.

Mum Sarah, 51, a home educator, said: “The genetic tests carried out by Professor John Sayer and his team allowed Casper to receive his diagnosis before he was symptomatic.

“The knowledge that Casper will go into kidney failure and eventually need a transplant, though overwhelming at times, has meant that we can arrange the support he needs and help him prepare for surgery and treatments well before they are necessary.

“When nobody is able to explain why your children are ill, it is very unsettling, with no means of clarifying what might happen in the future. The diagnosis has meant that we have been able to prepare ourselves for the medical issues our children face.

“It’s great that this research is being carried out at Newcastle University as it means patients with the condition can get a better understanding of their medical needs and hopefully new treatments may be developed in the future thanks to the research that is being done.” 

Sarah and husband, Darryl, 52, a chartered building surveyor, have been strong advocates for kidney patients and work with Kidney Research UK to help support patients.

New study provides insights into COVID-19 vaccine uptake among children and young people

COVID-19 vaccine uptake among children and young people was low across all four UK nations according to pioneering new research

SWANSEA UNIVERSITY

COVID-19 vaccine uptake among children and young people was low across all four UK nations, compared to other age groups, according to the first research study to look at data from all four UK nations.

It also revealed that uptake further reduced for second and booster vaccinations.

Uptake of COVID-19 vaccination was associated with age and sex of the child and young person, as well as number of people and vaccination status of the household.

The research, led by Professor Rhiannon Owen at Swansea University and Professor Sir Aziz Sheikh at the University of Edinburgh, linked health and administrative data to explore COVID-19 vaccine uptake in over 3.4 million children and young people aged between 5 and 17 in the UK.  

The research, published in Nature Communications, was a collaboration between Swansea University, the University of Oxford, Queen's University Belfast, the University of Edinburgh, and Strathclyde University.

The study looked at anonymised data between August 4, 2021, and May 31, 2022. It explored the factors influencing vaccine uptake among children and young people, including sex, age, and household factors, while accounting for delays in vaccine uptake due to infection.

The study used multi-state modelling and meta-analysis techniques to identify key demographic variables influencing vaccine uptake among children and young people on a national scale.

The study showed that across the UK nations 35 per cent of children and young people received the first vaccine, 21 per cent received the second, and 2 per cent received the booster dose. During the study period 13 per cent tested positive for COVID-19 and 133 died of all-causes.

Children and young people aged five to 11 years old were 90 per cent less likely to receive their first COVID-19 vaccine, and 12 to 15-year-olds were 42 per cent less likely compared to 16 to 17-year-olds.

The researchers revealed that children and young people in unvaccinated households were 81 per cent less likely to receive their first COVID-19 vaccine compared to children and young people from households with at least one vaccinated adult.

Males were 7 per cent less likely to receive their first vaccine compared to females, and children and young people residing in single adult households were 11 per cent less likely to receive their first vaccine compared to children living in households with two people.

First author Sarah Aldridge, researcher and data scientist at Population Data Science at Swansea, said:  “Our research emphasises the critical role of prioritising COVID vaccination efforts for children and young people. The data highlights the necessity for targeted interventions to address specific risk factors, ensuring widespread protection and mitigating potential impacts on this age group.

“To prepare for possible future pandemics, understanding and addressing vaccination differences among vulnerable populations are critical to effective public health strategies."

Can taking antibiotics combat the gut bacteria that contribute to the pathogenesis of COVID-19?

WILEY

New research indicates that antibiotics can effectively target bacteria in the gut that harbor the virus that causes COVID-19 and produce toxin-like peptides that contribute to COVID-19-related symptoms. In the study, which involved 211 participants and was published in the Journal of Medical Virology, individuals who received early antibiotic treatment after having COVID-19 recovered more quickly than those who did not receive antibiotics.

The authors had already evaluated the efficacy of certain antibiotics in SARS-CoV-2-infected bacterial cultures in vitro, and this new study demonstrates promising results with the use of the combination of 2 antibiotics (amoxicillin and rifaximin) within the first 3 days.

Furthermore, a significant number of patients who received antibiotics within the first 3 days and for a duration of 7 days during the acute phase of COVID-19 did not develop long COVID.

"Our findings suggest that antibiotics should be considered in acute infection and Long COVID. The study also lays the foundation for additional vaccine strategies," said co–corresponding author Marina Piscopo, PhD, of the University of Naples Federico, in Italy.

Researchers at the Niels Bohr Institute, University of Copenhagen and University of Southern Denmark have recently published FreeDTS – a shared software package designed to model and study biological membranes at the mesoscale – the scale “in between” the larger macro level and smaller micro level.

This software fills an important missing software among the available biomolecular modeling tools and enables modeling and understanding of many different biological processes involving the cellular membranes e.g. cell division.

Membrane shape contains information about the physiological state of the cell and overall health of an organism, so this new tool, with its wide array of applications, will enhance our understanding of cell behavior and open routes for diagnostics of infections and diseases like Parkinsons.

The publication of FreeDTS is now reported in Nature Communications.

Sharing a powerful tool that could have provided NBI with an advantage. Why?

The software package Weria Pezeshkian from the Niels Bohr Institute has been working on for the last 5 years, after an initial idea between him and John Ipsen from the University of Southern Denmark, is shared – laid open for every researcher in this field to use.

Normally the competition for achieving scientific results is high, and science advancements kept secret until publication – so this seems like a very generous attitude indeed. So generous it might seem a bit naive.

It is a strange mix of respect for the “pioneers” of the biomolecular modeling field and the fact that the field offers so many unanswered questions that it would seem almost disrespectful towards the scientific community to keep the tool to ourselves, Weria Pezeshkian explains.

“There are so many questions and bottlenecks to tackle to reach the end goals, that it would be unlikely that we work on exactly the same problems. However, occasional overlap occurs and is a worthwhile cost we pay for advancing the field.

But there is another aspect as well: One of the reasons our community, the biomolecular simulation and modeling community has had this surge in popularity and a fast growth is that we’ve always strived to get more people into the game and share ideas, results and methods and often direct assistance without expecting immediate personal gains.

This culture was built by the early pioneers in the field, for one, late , who always promoted this approach of sharing and bringing people in – so we are to a large extent standing on the shoulders of giants in this respect”.

Acknowledging Herman Berendsen

Herman Berendsen (1934-2019) was a professor of physical chemistry at the University of Groningen (RUG). He was especially known for his contributions to the field of molecular modeling and his dedication to translate models into accessible applications.

Berendsen was especially praised for his non-hierarchical and open approach. This not only locally at his institute, where he was known for enabling the young researchers in his group, but also among the wider scientific community. He contributed to computer simulation applications that are still widely used to study the dynamics of biomolecules. Examples of this are his SPC (simple-point-charge) model, used to model liquid water; and the ‘Berendsen’ thermostat and barostat, that serves to keep the temperature and pressure constant during simulations.

Also, he organized a series of workshops where pioneers in the field met to discuss and share their newest findings.

Berendsen remains one of RUG’s most cited scholars. The applicability of his work ranges far beyond the field of physical chemistry and it is also used by mathematicians, computer scientists, molecular life scientists and in the development of medical applications.

Biological membranes – what are they really?

When you consider a cell, you can imagine a whole lot of small “factories” inside, called organelles, doing their thing – surrounded by a membrane.

The cell also is surrounded by a membrane called Plasma membrane. But membranes are not just a boundary surface. They are actively participating in many processes. They are made from a myriad of different molecules, and they are dynamic, in motion all the time.

Many diseases are associated with irregular membrane shape and abnormal biomolecular organization, so the study of membranes can help us understand the  state of a cell and overall  health of an organism. For instance, when a neuron has increased spiking activity, indicating a higher energy demand, the structure of mitochondria, an organelle responsible for generating cellular energy parcels from food (often referred to as the powerhouse of the cell), undergoes changes.

Moreover, certain diseases, e.g., Alzheimers for one, have been associated with changes in the mitochondrial membranes shapes.

Computer models will improve our abilities within diagnostics

“For now, we are not able to see exactly what the exact causes of changes in membrane shape are and how are they exactly related to the diagnostics of a certain disease. But at some point, in the future, the try and error works in the lab will become minimal because modelling will guide experiments with unimaginable accuracy, as our modeling becomes more precise and the power of computational options increasing.

We will need a lot of adjustments and there is still long way to go, so it is really nice to work within this sharing community, because we all work on different aspects of it” Weria Pezeshkian explains.

Weria continues with a word of caution: “This is probably stretching it a bit far, but possibly, in the future, by imaging for example our mitochondria and leveraging physics-based computer simulations we may be able to say: This person has this disease with this specific genetic deficiency. So, the perspective for computational modelling is rather great – we are not there yet, but we can see it in the horizon”.

Is active screening for tuberculosis among vulnerable populations cost-effective?

In their systematic review published in Eurosurveillance prior to World TB Day, Gogichadze et al. explore this question particularly for settings with a low incidence of TB cases.

EUROPEAN CENTRE FOR DISEASE PREVENTION AND CONTROL (ECDC)

Early detection and prompt treatment of tuberculosis (TB) are main pillars on the way to end TB as it helps preventing further transmission. Finding those at risk of developing infection, however, requires extra efforts particularly in settings where TB incidence levels are generally low, i.e. when there are less than 10 TB cases per 100,000 population.

This is where active screening targeting populations at higher risk of TB infection, which include people in urban aeras with lower incomes, people experiencing homelessness, communities in remote or isolated areas, indigenous populations, migrants, refugees, internally displaced persons and other vulnerable or marginalised groups with limited access to healthcare, could help detecting (latent) infections.

In the Eurosurveillance issue marking World TB Day 2024 [1], Gogichadze et al. [2] present the findings of their systematic review on active pulmonary TB screening programmes run between 2008 and 2023 in so-called high-risk groups living in low TB incidence countries. The authors wanted to identify if active searches for pulmonary TB would be cost-effective given that passive case finding approach may not be sufficient in the effort of detecting and treating TB patients.  

Active case finding makes a difference
In their search, the authors found 6,318 articles based on their search criteria and included nine of them in their review with the specific angle of active case finding that e.g. included chest X-ray, tuberculin skin test, interferon-gamma release assay and a symptoms questionnaire for screening.

Analysing the results of the reviewed articles, Gogichadze et al. conclude that “screening immigrants from countries with a TB incidence with more than 40 cases per 100,000 population and other vulnerable populations as individuals from isolated communities, people experiencing homelessness, those accessing drug treatment services and contacts, is cost-effective in low-incidence countries”.

A comparison between levels of cost-effectiveness was, however, not possible due to the data heterogenicity and, according to the authors, requires further harmonisation of the methods for cost-effectiveness analysis.

They summarise that “based on the findings spanning 16 years and the guidelines available, we have listed several recommendations for optimising study design for active screening programmes for TB in low-incidence countries. Firstly, to guide policymakers, cost-effectiveness analysis should always be part of TB screening activities targeting high-risk groups in low TB incidence countries. Additionally, cost-effectiveness studies should follow national economic evaluation guidelines in case they are available and consider the published WHO guidance. Moreover, the cost-effectiveness analysis should encompass not only the expenses related to screening, but also those related to diagnosis and treatment.”

Mount Sinai is first in New York to study a brain-computer interface designed to record and map the brain’s activity in unprecedented detail

A multidisciplinary team of neurosurgeons and neuroscientists from the Icahn School of Medicine at Mount Sinai are the first in New York to study a new brain-computer interface that’s engineered to map a large area of the brain’s surface, in real time, at resolutions hundreds of times more detailed than typical arrays used in neurosurgical procedures.

A brain-computer interface (BCI) is a system that deciphers brain signals and translates them into commands for external technologies. The ultimate goal of a BCI is to restore function to patients with debilitating neurological conditions by enabling them to operate digital devices using only their thoughts.

The Layer 7 Cortical Interface, developed by Precision Neuroscience Corporation, contains 1,024 tiny electrodes spanning an area of 1.5 square centimeter, embedded in a flexible film that conforms to the brain’s surface. The film is one-fifth the thickness of a human hair and was designed to be implanted and removed by neurosurgeons without damaging brain tissue.

“Mount Sinai has established an international reputation for our ability to conduct the most advanced biomedical and scientific research, for our commitment to exceptional patient care, and for our entrepreneurial approach to generating new treatments and advancements in care,” said Joshua B. Bederson, MD, Chair of Neurosurgery at the Mount Sinai Health System and Co-Founder of Mount Sinai BioDesign. “This culture of excellence, innovation, and collaboration attracts some of the brightest and best clinicians and researchers in the world who are capable of rapidly translating research breakthroughs into new products and services that provide meaningful benefit to patients and our society. We are proud to be one of the leading sites participating in the trials for the new array and eager to see what we learn from the detailed information we will collect and analyze.”

As part of an open-label, single-arm feasibility study, Mount Sinai neurosurgeons are temporarily placing the investigational device on the surface of the study participants’ brains during intracranial procedures where surface mapping is routinely performed and correlated to evoked potentials (tests that measure the brain’s response to sensory stimulation) or standardized behavioral tasks that are routinely performed as part of these procedures. The device records high-resolution electrophysiological signals and the data collected is compared to that obtained using standard-of-care cortical surface arrays.

A team of Mount Sinai neuroscientists who have deep expertise in human electrophysiology will analyze and interpret the massive amount of data collected from the device. A secondary objective of the study is to assess the ability of the thin-film electrode to map electrophysiological correlates of awake behavioral tasks, including motor, speech, and cognitive tasks.

“Despite the vast complexity of activity across the human brain, standard monitoring tools can only capture a tiny fraction of the data we need—from a small handful of areas, or at very slow temporal resolution. This low-resolution data significantly limits our understanding of brain function and brain disorders,” says Ignacio Saez, PhD, Associate Professor of Neuroscience, and Neurosurgery, Director of the Human Neurophysiology Laboratory, and Principal Investigator of the trial at Icahn Mount Sinai. “The new device is exciting because it provides us with an extremely detailed depiction of electrical activity in the brain, capturing thousands of data points per second from a thousand brain sites in each participant. By monitoring neuronal activity at this unprecedented resolution, our interdisciplinary team at Mount Sinai hopes to gain important insights into how brain function supports behavior and is affected by disease states. Our ultimate goal is to obtain actionable knowledge that will open the door to new treatments for neurological and psychiatric disorders and improve quality of life for our patients.”

Precision Neuroscience was co-founded by Benjamin Rapoport, MD, PhD, Assistant Professor of Neurosurgery at Icahn Mount Sinai, a practicing neurosurgeon who has a PhD in electrical engineering and computer science. Dr. Rapoport also serves as the Scientific Director of Mount Sinai BioDesign, a medical technology prototyping center and incubator housed within the Mount Sinai Health System.

There were multiple unsafe sleep practices at play in more than three-quarters of Sudden Unexpected Infant Deaths reported in 23 jurisdictions between 2011 and 2020, a new study reveals. The researchers say the findings underscore the need for more comprehensive safe-sleep education for new parents, including from healthcare providers.

Of 7,595 infant deaths reviewed, almost 60% of the infants were sharing a sleep surface, such as a bed, when they died. This practice is strongly discouraged by sleep experts, who warn that a parent or other bed partner could unintentionally roll over and suffocate the baby.

Infants who died while sharing a sleep surface were typically younger (less than 3 months old), non-Hispanic Black, publicly insured, and either in the care of a parent at the time of death or being supervised by someone impaired by drugs or alcohol. These infants were typically found in an adult bed, chair or couch instead of the crib or bassinet recommended by sleep experts.

“The large number of hazardous sleep practices for both infants who were sharing a sleep surface and sleeping alone at the time of death is alarming,” said researcher Fern Hauck, MD, MS, a safe-sleep expert at UVA Health and the University of Virginia School of Medicine. “These are known risk factors for SUID [Sudden Unexpected Infant Death], and tells us that we need to do a better job of working with families to increase acceptance of the recommendations to create safer sleep spaces for their infants.” 

Sudden Unexpected Infant Deaths

To better understand the factors contributing to SUID and improve safe-sleep messaging, Hauck and her collaborators analyzed data from the federal Centers for Disease Control and Prevention’s SUID Case Registry. That data reflects localities from Alaska to Wyoming, including the Tidewater area of Virginia. 

Examining the registry allowed the researchers to obtain important insights on the prevalence of practices such as prenatal smoking, a known risk factor for SUID, and breastfeeding, which is thought to have a protective benefit. More than 36% of mothers of infants who died had smoked while pregnant. This percentage was higher among moms who bed shared than those who didn’t, 41.4% to 30.5%. Both bed sharers and non-bed sharers had breastfed at similar rates. 

The researchers note that it was rare for bedsharing to be the only risk factor present during a child’s death. The findings highlight the need for better public education about safe-sleep practices, and for care providers to take a more active role in teaching new parents about the practices, the researchers say.

 “Our findings support comprehensive safe sleep counseling for every family at every encounter beyond just asking where an infant is sleeping,” the researchers write in a new paper in the journal Pediatrics.

In addition to helping parents understand safe-sleep practices, care providers should take steps to ensure parents can follow those practices once they leave the hospital. For example, some families may not have the means to purchase a crib or bassinet; a hospital might direct them to resources to help with that.

“SUID deaths in the U.S. are still higher than in most other countries, and this is unacceptable,” Hauck said. “Clinicians and others caring for infants need to have thoughtful conversations with families at risk to understand the barriers to following safe-sleep guidelines and find ways to work together to overcome them.”
