Racial justice activism, advocacy found to reduce depression, anxiety in some teens



Results of mental health intervention presented during the American Academy of Pediatrics 2024 National Conference & Exhibition



American Academy of Pediatrics




ORLANDO, Fla.—Black and LatinX teenagers enrolled in an 8-week racial justice activism program reported fewer symptoms of depression and anxiety, according to research presented during the American Academy of Pediatrics 2024 National Conference & Exhibition in Orlando, FL.

The research, “Our Voices Matter Pilot Study: A Racial Justice Activism Intervention to Reduce Depression in Adolescents,” will be presented during the conference at the Orange County Convention Center Sept. 27-Oct. 1.

The study followed seven Black and LatinX teens who engaged in 90-minute virtual sessions and learned about activism and social change through a critical examination of race and racism from February to April 2023. Participants reported a 38% reduction in reported depressive symptoms after four sessions and a 45% reduction by the end of the intervention.

“This research is groundbreaking because it demonstrates the transformative power that activism could have on the mental health of Black and Latinx youth,” said Billie Patterson, a UQ Ochsner medical student with the with the ARISE Health Lab. “The potential to harness advocacy efforts as a therapeutic tool is an exciting frontier for both health promotion and social justice.”

The authors observe that the murders of George Floyd and Breonna Taylor ignited protests that drew over 15 million participants, underscoring activism as a unified response against racism. Structural racism and discrimination are well known contributors to chronic stress and health disparities, including conditions such as metabolic syndrome, obesity, and diabetes.

The teens focused their efforts on the school-to-prison pipeline, delving into national and local contexts using primary sources. They devised social media campaigns raising awareness and prompting action concerning inadequate mental health resources in schools and the racial disparities present in school disciplinary procedures.

Participants completed baseline, mid-point, and post-intervention measures of depression and measures about intervention acceptability and adherence.

“The activism intervention we piloted resulted in clinically meaningful reductions in depressive symptoms and we observed an upward trend in measures of resilience,” said Nia Heard-Garris, MD, MBA, MSc, FAAP, lead researcher and pediatrician at Lurie Children’s and Assistant Professor of Pediatrics at Northwestern University Feinberg School of Medicine.

“We learned that teens loved having a safe space and learning how to help their community.,” Dr. Heard Garris said. “We also were excited to see that these teens continued to engage with advocacy long after the end of the pilot study.”

Study author Billie Patterson is scheduled to present the research, which is below, from Sunday, September 29, 2024, 4:30-5:30 pm at the Hyatt Regency Orlando, Plaza International Ballroom. 

In addition, Billie Patterson will be among highlighted abstract authors who will give brief presentations and be available for interviews during a press conference from noon-1:30 pm ET in the National Conference Press Room, W208 AB.

Abstract Title: Our Voices Matter Pilot Study: A Racial Justice Activism Intervention to Reduce Depression in Adolescents

Westville, IN, United States

The murders of George Floyd and Breonna Taylor ignited protests that drew over 15 million participants, underscoring activism as a unified response against racism. Black and Latinx youths experience adverse mental health impacts due to racism and may engage in racial justice activism (RJA) to mitigate these effects. RJA encompasses efforts to combat racial injustice through political, communal, and interpersonal means. Limited research has explored RJA's potential as a beneficial coping mechanism for the mental well-being of Black and Latinx adolescents. The RJA Our Voices Matter pilot study aims to fill this gap by evaluating the impact of this intervention on adolescents’ depression and anxiety.

The RJA intervention was piloted February-April 2023, with 7 Black and Latinx adolescents in Chicago, IL (Mage = 16, SD = 1.3). Across 8 weeks, the group engaged in 90-minute virtual sessions. Participants learned about activism and social change through a critical examination of race and racism. The adolescents elected to concentrate their activism efforts on the school-to-prison pipeline, delving into national and local contexts using primary sources. They then devised social media campaigns raising awareness and prompting action concerning inadequate mental health resources in schools and the racial disparities present in school disciplinary procedures. Participants completed baseline, mid-point, and post-intervention measures of depression (Patient Health Questionnaire-9), anxiety (General Anxiety Disorder-7) and measures about intervention acceptability and adherence.

Using Wilcoxon non-parametric signed-rank test, we found a statistically significant decrease in depressive symptoms from week 1 (M = 11.3) to week 8 (M = 6.2; z = -2.21, p = .03, r = -0.64). Participants had a 38% reduction in depressive symptoms by week 4, and a 45% reduction by week 8. The five-point reduction from week 1 to week 8 met the minimum clinically important difference, moving the average from moderate to mild depressive symptoms. Additionally, participants reported a reduction in anxiety symptoms from week 1 (M = 11.3) to week 8 (M = 7; z = -1.63, p = 0.1, r = -0.47), although it was not statistically significant. On a Likert scale from 1 (strongly disagree) to 7 (strongly agree), participants reported that sessions were helpful (M = 5.83), and an appropriate length (M = 5.67). The attendance rate was 71%-100%, with absence due to school and civic engagement activities.

The Our Voices Matter RJA intervention produced both a statistically significant and clinically meaningful reduction in depressive symptoms for Black and Latinx adolescents. Despite the adverse effects of racism on adolescent mental health, this study has demonstrated racial justice activism can serve as an adaptive coping strategy to enhance wellbeing. In the future, RJA must be examined as a health-promotion strategy to address the mental health burden that Black and Latinx adolescents face.

Racial disparities exist in emergency department treatment of children with unintentional ingestions



Research found that Black children seeking emergency treatment for an unintentional ingestion more likely than white children to be referred for social worker and Children Services Bureau interventions



American Academy of Pediatrics





ORLANDO, Fla.— Unintentional injuries like falls, drownings and poisonings are the leading cause of death in patients ages 1-4, and a significant portion of these deaths are linked to unintentional ingestions—such as swallowing a drug or poison. New research shows racial and socioeconomic disparities exist in the emergency management of unintentional ingestions in children.  

Black patients younger than age 6 with the diagnosis of unintentional ingestion were more likely than white children to have a social work consult, Children Services Bureau referral, and urine drug screen, according to a research abstract, “Disparities in the Emergency Evaluation and Management of Unintentional Ingestions in Preschool Children,” presented during the American Academy of Pediatrics 2024 National Conference & Exhibition at the Orange County Convention Center from Sept. 27-Oct. 1.  

The research also found that children from poorer backgrounds (lower childhood opportunity index), those with higher severity of illness and pharmaceutical ingestions resulted in either a social work consultation, a Children Services Bureau referral, or both.  

“This study is important in understanding where underlying bias exists in emergency departments and hospital management and where changes can be made to address this problem, thus providing equitable care for all children,” said principal investigator Jennifer Allen, DO, FAAP.  “These findings could be useful to healthcare workers in emergency departments to help develop a framework for standardized clinical decision making.” 

Researchers examined the records of 4,411 patients, younger than age 6, who had unintentional ingestions between January 2013 and March 2024 identified by the International Classification of Disease in the electronic health record. They found: 

  • Most ingestions were non-pharmaceutical (56%) 

  • Patients with pharmaceutical ingestions had higher odds of a social work consult and a Children Services Bureau referral 

  • Independent of ingestion type, non-white children were more likely to have a social worker consult or Children Services Bureau referral  

  • White children were less likely to be exposed to cannabis 

  • Private insurance was associated with reduced odds of social worker or Children Services Bureau referral.  

“This isn’t the only research to find racial disparities in the emergency department,” Dr. Allen said. “Disparity has been identified among different races regarding pain management for fractures and appendicitis in the emergency department.” 

Akron Children’s Hospital supported this research.  

Study author Dr. Jennifer Allen is scheduled to present this research, which is below, from 2:30 - 2:40 p.m. Friday, Sept. 27, 2024, during the Section on Emergency Medicine program during the AAP’s National Conference and Exhibition.

ABSTRACT 

 

Program Name: 2024 AAP National Conference-Abstracts 

Submission Type: Section on Emergency Medicine 

Abstract Title: Disparities in the emergency evaluation and management of unintentional ingestions in preschool children 

Unintentional injuries consisting of trauma and poisonings are the leading cause of death in patients aged 1-4 years old with a significant portion attributed to ingestions. National Poison Control data in 2021 showed there were 37 incidences of poison exposure per 1000 children under 6 years old (2023). Between 2010-2019, poisoning deaths among minority children increased (West, 2021). Evidence of treatment disparity exists as seen in the decreased use of opioids or analgesia in minority children with long bone fractures or appendicitis in the emergency department (ED) (Goyal, 2015 and 2020). There is a knowledge gap regarding the extent, causes, and impact of disparities in assessing and managing acute ingestions in children. This study aimed to determine whether there is a difference in the evaluation and management of children with unintentional ingestions in a pediatric tertiary care center’s ED. 

From January 2013 to March 2024, patients less than 6 years of age were identified by International Classification of Disease (ICD) 9 and 10 codes in the electronic health record (EHR). Independent variables included: race, childhood opportunity index (COI), payor status, severity, age, sex, and substance type. Dependent variables included: urine drug screen (UDS), social work (SW) consult, and child service bureau (CSB) referral. Summary statistics were calculated and described as mean (sd). The relationship between independent and dependent variables was described using odds ratio (OR) with 95% confidence interval (CI). The relationship between pharmaceutical ingestion type was described using the receiver operating characteristic curve (ROC). Significance was defined as p-value < 0.05. Races are defined as White, African American, and Other; due to low numbers in categories comparisons are between all White and Non-White children. 

4411 patients had unintentional ingestions and most ingestions were non-pharmaceutical (56%). Patients with pharmaceutical ingestions had higher odds of a social work consult and a CSB referral (OR 8.3, 9.0). Independent of ingestion type, Non-White children were more likely to have a SW consult, CSB referral, and UDS order (ROC 0.78, 0.84, and 0.86). Looking at pharmaceutical ingestions, Non-White children had more cannabis ingestions than White children (Figure 1). Private insurance and ED discharge were associated with reduced odds of SW consults or CSB referral. A lower COI was associated with higher odds of SW consult and CSB referral (Table 1). When adjusted for COI, payor type, and severity, African Americans had higher odds of a SW consult, CSB referral, and UDS order (OR 1.8, 2.8, 2.3). 

This study revealed there are racial disparities in the management of unintentional ingestions within the ED setting. The next step would be to discuss findings with ED professionals and develop a framework for standardized clinical decision making. 


Childhood opioid prescription rates vary by patient’s background, research finds



Research presented during American Academy of Pediatrics 2024 Conference & Exhibition analyzes opioid prescriptions following fracture diagnoses




American Academy of Pediatrics





ORLANDO, Fla.—Children born to greater socioeconomic backgrounds are significantly more likely to be prescribed opioids, according to research presented during the American Academy of Pediatrics 2024 National Conference & Exhibition at the Orange County Convention Center from Sept. 27-Oct. 1. 

The abstract, “Overprescription of Opioids in White Children from Higher Socioeconomic Backgrounds: Disparities in Opioid Utilization for Pediatric Supracondylar Humerus Fractures,” looked at the rates in opioid prescriptions following childhood broken elbow diagnoses from 2012 to 2021.

Apurva Shah, MD, MBA, Attending Surgeon, Orthopaedic Surgery at the Children’s Hospital of Philadelphia, who authored the abstract, also pointed to results that showed a third of patients in the abstract received at least one opioid dose during their visit.

“As orthopaedic surgeons, we clearly need improved opioid use stewardship to improve healthcare outcomes for our patients,” Dr. Shah said.

Results found disparities in patient racial backgrounds, with Black children 27% less likely to receive an opioid prescription compared to other patients. By comparison, white patients were also shown to be 10% more likely to be given opioids.

Other factors that impacted patients’ likelihood of being given opioids included age and where they live, according to Dr. Shah.

“Non-opioid pain management has proven sufficient for pain management,” Dr. Shah said. “Knowing this, along with this abstract, pediatricians must consider the potential harm these drugs can have on populations with disproportionately easier access to healthcare.”

This research was funded by Children’s Hospital of Philadelphia, Division of Orthopaedics.

Scott Mahon is scheduled to present the research, which is below, at 8:51 – 8:55  a.m. on Sunday, Sept. 29 during the Section on Orthopaedics program at Orange County Convention Center, West Building, W311H. To request an interview with the authors, contact Ashley Moore at moorea1@chop.edu.

Abstract Title: Overprescription of Opioids in White Children from Higher Socioeconomic Backgrounds: Disparities in Opioid Utilization for Pediatric Supracondylar Humerus Fractures

Apurva Shah

Philadelphia, PA, United States

Nonmedical use of opioids in children and adolescents is a well-established public health concern. For many adolescent patients, an initial opioid prescription can act as a gateway that may lead to opioid misuse later in life. The purpose of this study is to investigate if patient factors, including sex, race, ethnicity, or Childhood Opportunity Index (COI), are associated with higher or lower likelihood of opioid prescription in children with fractures, utilizing pediatric supracondylar humerus fracture as an archetypal example.

Data was obtained from the Pediatric Health Information System (PHIS), an administrative database consisting of patient encounters across 52 pediatric hospitals. Patients with supracondylar humerus fractures who presented to an emergency department and were treated non-operatively were included. The primary outcome variable of interest was whether or not patients received an opioid prescription. We also extracted and assessed patient-level predictors for opioid use, including age, sex, race, ethnicity, primary payer, COI, and geographic region. To account for hospital level variation, we conducted mixed-effects logistic regression.

In total, 35,452 children (52% male) with non-operative supracondylar humerus fractures at a mean age of 5.7 ± 2.8 years were included. About one-third of patients (10,731; 30.3%) received at least one dose of opioids. After accounting for hospital-level characteristics, White patients were significantly more likely to receive an opioid prescription (OR 1.1, p=0.016), while those with public insurance were less likely (OR 0.85, p=0.001). Kids from moderate, high, and very high COI regions were significantly more likely to receive opioids compared to very low COI regions (OR 1.1-1.2). Additionally, older children (5-13 years) were significantly more likely to be prescribed more opioids compared to younger children (1-5 years) (OR 1.4, p< 0.001). No differences due to region or sex were found statistically significant. Results are further described in Table 1.

Opioids for supracondylar humerus fractures, despite the efficacy of non-opioid alternatives, are prescribed at high rates and disproportionately to White children and patients from higher COI areas, reflecting important socioeconomic disparities in opioid prescription patterns. Though non-opioid pain management using acetaminophen or ibuprofen provides sufficient pain control for treating supracondylar humerus fractures, unfortunately, almost one-third of patients being treated non-operatively were prescribed opioids. Our investigation demonstrates that White patients and children with higher COI are especially likely to be prescribed opioids, indicating that prescription pattern disparities may be harming the portion of the population that has historically had better access to healthcare.


Black infants with heart abnormalities more likely to die in first year



Study of infant mortalities from heart defects finds while death rates decreased, white infants more likely to survive than Black infants

Reports and Proceedings

American Academy of Pediatrics





ORLANDO, Fla.— Some babies are born with abnormalities involving the structure of the heart, known as congenital heart disease (CHD). While many studies have shown that more babies with congenital heart disease are surviving past their first birthday as deaths from CHD have significantly decreased in the United States, a research abstract found that race impacts these survival rates.

Black infants with congenital heart disease are 40% more likely to die in the first year of life than white infants with congenital heart disease, according to research presented during the American Academy of Pediatrics 2024 National Conference & Exhibition at the Orange County Convention Center from Sept. 27-Oct. 1.

The research, “Trend in Racial Differences in Mortality Attributed to Congenital Heart Diseases in Infants in the United States from 2005 to 2019," found that improvements in death rates for children with heart abnormalities were due to reduced death rates for white babies with congenital heart disease.

“The death rate in white infants decreased significantly but the rate in Black infants did not. Overall, we also found that Black infants died from these abnormal heart structures at a rate that was 1.4 times that of white infants,” said lead author Kwadwo Danso, MBChB.

Researchers examined data from the Centers for Disease Control and Prevention on 60,243,988 live births, which included 19,004 congenital heart disease-related infant deaths, to investigate if death rates varied based on race for children born with CHD. They found that the overall congenital heart disease infant mortality rate declined from 36.1 to 27.0 per 100,000 live births, down 25.2%. However, throughout the study, Black infants with congenital heart disease died at higher rates.

“Our findings may have implications for patient care and public health policy by serving as a foundation for additional studies to determine the drivers behind these disparities,” Dr. Danso said. “More research is needed on this disparity to understand why Black infants with congenital heart disease are more likely to die.”

Study author Kwadwo Danso, MBChB, is scheduled to present the research, which is below, during the Section on Cardiology and Cardiac Surgery program at the AAP’s National Conference and Exhibition.

Abstract Title: Trend in racial differences in mortality attributed to Congenital Heart Diseases in infants in the United States from 2005 to 2019

Peoria, IL, United States

Deaths from congenital heart disease (CHD) in children have been decreasing. We examined the differences in CHD mortality trends between Non-Hispanic Black (NHB) and Non-Hispanic White (NHW) infants in the United States from 2005 to 2019. We hypothesized that a disparity in mortality rates exists between NHB and NHW infants.

We performed a retrospective cross-sectional analysis of publicly available data from the Centers for Disease Control and Prevention’s Wide-ranging Online Data for Epidemiologic Research. The data was obtained from the linked birth/infant deaths from 2005 to 2019. We evaluated all infant deaths up to 1 year of age with the cause of death listed as CHD (International classification of diseases, 10th revision (ICD-10) codes Q20-Q26 (except atrial septal defect, Q21.1 and patent ductus arteriosus, Q25. CHD infant mortality rate (IMR) was calculated per 100,000 live births. Race was ascertained based on death certificate reporting. Joinpoint regression was used to examine CHD-IMR by year, including stratification by NHB vs NHW. The difference between NHB and NHW CHD-IMR was ascertained via the Mann-Whitney U test. P< 0.05 was considered statistically significant.

Out of 60,243,988 live births, there were 19,004 CHD-related infant deaths. The characteristics of the study population are displayed in Table 1. The overall CHD-IMR declined from 36.1 to 27.0 per 100,000 live births (25.2%) with an average annual percentage change (AAPC) of -2.1 [95% confidence interval (CI)-2.6, -1.572] (Figure 1). The CHD-IMR was significantly higher in NHB than in NHW (40 vs 29.3; P< 0.0001) and this difference remained when the CHD mortality rate was stratified by the neonatal and post-neonatal period. The CHD-IMR decreased significantly in NHW [AAPC: -2%; 95% CI: -2.5, -1.5%], however, it was not significant in NHB [AAPC of -1.4%, 95% CI, -3.0, 0.3%]. The NHB-to-NHW CHD-IMR ratio, a measure of CHD-IMR disparity averaged 1.4 and there was no significant change during the study period [AAPC: 0.8%; 95% CI: -0.2, 1.8%] (Figure 2).

The CHD-IMR declined significantly for NHW, but not in NHB in the US from 2005 to 2019. The CHD-IMR was significantly higher in NHB than in NHW. There was no significant change in the NHB-to-NHW CHD-IMR ratio, signifying no change in the disparity that exists between NHB and NHW IMR. These findings may have implications for patient care and public health policymaking. They lay the groundwork for additional studies to determine and understand the drivers behind these findings such as in prenatal diagnosis.

Preterm births are on the rise, with ongoing racial and economic gaps



Study identifies how changes in risk factors may be contributing to growing number of babies born prematurely



Peer-Reviewed Publication

New York University





Preterm births have increased by more than 10 percent over the past decade, with racial and socioeconomic disparities persisting over time, according to a new study analyzing more than five million births.

The study, published in the journal JAMA Network Open, also found that some factors that increase the risk for preterm birth—such as diabetes, sexually transmitted infections, and mental health conditions—became much more common over the past decade, while other factors that protect against preterm birth declined. 

“Our findings not only show that preterm births are on the rise, but provide clues as to why this may be the case,” said Laura Jelliffe-Pawlowski, the study’s lead author, an epidemiologist and professor at the NYU Rory Meyers College of Nursing and professor emeritus of epidemiology, biostatistics, and of global health sciences in the University of California San Francisco (UCSF) School of Medicine. “Understanding patterns of and factors related to preterm birth is important for informing clinical care and the development of public health programs to address this critical need.”

Babies born preterm or prematurely—before the 37th week of pregnancy—are more likely to experience a range of short and longer-term problems, including a higher risk for illness, intellectual and emotional difficulty, and death. Certain factors are known to increase the risk of preterm birth, including mothers having high blood pressure, diabetes, an infection, or smoking. In addition, Black, Native American, and Hawaiian and Pacific Islander expectant mothers are at higher risk for preterm birth, which is thought to be driven by a long history of structural racism experienced by these groups.

To understand recent trends around preterm births, Jelliffe-Pawlowski and her colleagues looked at more than 5.4 million singleton births (not twins or other multiples) from 2011 to 2022 in the state of California. They examined how preterm birth rates changed over time and explored patterns in risk and protective factors within racial/ethnic and socioeconomic groups. Health insurance type was used as a proxy for socioeconomic status, comparing public insurance (MediCal, California’s Medicaid program) with nonpublic insurance (including private insurance and coverage through the military and the Indian Health Service). 

A growing risk and “alarm bells”

The researchers found that preterm births increased by 10.6 percent over the decade studied, from 6.8 percent in 2011 to 7.5 percent in 2022—echoing a report from the Centers for Disease Control and Prevention (CDC) released earlier this year that also found an increase in preterm birth across the nation from 2014 to 2022.

Rates of preterm birth grew across nearly all groups, but varied by racial/ethnic and socioeconomic group. The highest rates of preterm birth were among Black mothers with public insurance (11.3 percent), while the lowest rates were among white mothers who had nonpublic insurance (5.8 percent). Preterm birth rates decreased slightly over time among Black mothers with nonpublic insurance, from 9.1 percent in 2011 to 8.8 percent in 2022, but were still significantly higher than rates among white mothers. In contrast, preterm birth rates jumped from 6.4 percent to 9.5 percent among Native American mothers with nonpublic insurance.

“We found stark differences in terms of what it looks like to be a Black or Native American pregnant person compared with a white individual who is of middle or higher income,” said Jelliffe-Pawlowski.

Expanding on the CDC report’s findings by looking at risk and protective factors over time, the researchers determined that several factors were linked to an increased risk for preterm birth, including diabetes, high blood pressure, previously having a preterm birth, having fewer than three prenatal care visits, and housing insecurity. Notably, the rates of preexisting diabetes, sexually transmitted infections, and mental health conditions more than doubled during the decade studied.

“These patterns and changes in risk factors should be setting off alarm bells,” said Jelliffe-Pawlowski. 

Several factors were found to protect against preterm birth among low-income expectant mothers, including receiving prenatal care and participation in WIC, the supplemental nutrition program supporting women and children. Unfortunately, the researchers observed a decline in WIC participation across most low-income racial/ethnic groups over the period studied.

What can be done to improve birth outcomes

The researchers note that their findings underscore the need to improve pregnancy care and promote treatments that address risk factors associated with preterm birth—which are often underutilized during pregnancy, especially among mothers of color.

“We need to do a better job of sharing information with pregnant people about risk factors for preterm birth and interventions that may be able to help them address this risk. Some providers report not wanting to scare or overwhelm pregnant people, but pregnant people tend to report wanting to have this information,” said Jelliffe-Pawlowski. “For those who are at increased risk due to factors like hypertension or previous preterm birth, for example, providers should be having conversations about how taking low-dose aspirin might be helpful to them and their growing baby. This also extends to things like screening for sexually transmitted infections and offering mental health care in a non-judgmental, supportive way.”

“There is also important work to be done to improve structural issues and respectful care in WIC to increase participation,” added Jelliffe-Pawlowski.

Jelliffe-Pawlowski and her colleagues are also working to develop a digital platform called Hello Egg to help expectant mothers better understand their risk for preterm birth, identify interventions that may be helpful to them, and create a healthy pregnancy plan co-developed with prenatal providers. Jelliffe-Pawlowski and the team at the start-up, EGG Healthy Pregnancy, aim to conduct a large study to see if using the platform boosts a pregnant person’s knowledge; a key outcome will be seeing if this information sharing leads to increases in the use of interventions and, ultimately, to a reduced risk of preterm birth and other adverse outcomes. 

The research was supported by the University of California, San Francisco California Preterm Birth Initiative. Additional study authors include Audrey Lyndon of NYU Meyers and collaborators from the University of California, San Francisco; University of California San Diego; Stanford University; UCLA Medical Center; California State University, Northridge; San Francisco State University; Indiana University Bloomington; University of Alabama at Birmingham; and the University of Illinois Urbana-Champaign.

A recent study has explored the recent advancements in the development of processable natural biopolymers and their myriad applications.

With the ever-expanding global population and rapid economic advancement, there is an escalating demand for materials, chemicals, and energy resources worldwide. A substantial proportion of these resources is currently sourced from fossil fuels. “Currently, approximately 8% of fossil fuels are used in polymer production, and this proportion is expected to projected to surge to 20% by 2050. This mounting demand for polymers, coupled with escalating processing costs, poses a formidable long-term challenge in meeting global polymer requirements. Moreover, the environmental impact of polymer usage, which is exacerbated by inefficient recycling systems and inadequate waste management infrastructure, underscores the pressing need for sustainable alternatives to synthetic polymers derived from fossil resources,” says Dr. Haijun He, one of the researchers.

In response to these imperatives, there has been a burgeoning interest in exploring processable natural biomass as a viable substitute, driven by growing concerns about the adverse environmental and economic consequences of dwindling fossil resources and petrochemicals. More specifically, next-generation, environmentally friendly, and cost-effective functional materials derived from natural biopolymers have received significant attention, particularly with the exponential increase in biowaste production. In addition to their exceptional sustainability and inherent biocompatibility, natural biopolymers possess unique hierarchical structures characterized by structural integrity, toughness, and flexibility, further enhancing their appeal for a wide range of applications.

Proteins and polysaccharides have garnered significant attention because of their abundance, availability, and versatility in various fields. The direct processing of proteins and polysaccharides into final products presents significant challenges owing to their innate ordered structural features spanning from the molecular to nanoscale and extensive hydrogen bonding networks at all levels. “This necessitates further modifications to enhance processability, such as extraction or isolation,” Haijun He says.

The sustainable production of these natural biopolymers and their versatile applications have been a long-standing pursuit. “Although hundreds of breakthrough studies have been conducted in this field, existing reviews on bio-material advances in environmental engineering and the biomedical field often focus exclusively on the preparation and specific application of individual natural biopolymers with less attention to processability, sustainability, and diverse applications,” Haijun He says, “Our objective is to comprehensively identify and address major material challenges and offer practical solutions to stimulate a material revolution in the domain of functional natural polymers.”

The number of tidal power and other offshore renewable energy installations is set to grow significantly around the UK coastline over the coming decades.

However, launching state-of-the-art devices into often turbulent ocean flows has the potential to pose a range of challenges for the tidal energy industry, including uncertainty around how they may interact with the environment.

To address that, a team of scientists used a combination of aerial drone technology and boat-based surveys to map out the complex tidal flows encountered by the world’s most powerful tidal turbine – Orbital Marine Power’s O2, sited in the heart of the Orkney Islands, Scotland.

Unlike conventional tidal stream turbines, the O2 floats on the sea surface, anchored by mooring lines to the seabed. The platform is over 70 meters long and is connected to the grid at the European Marine Energy Centre (EMEC), with estimates that it could power 2,000 UK homes per year.

The study included highlighting how changing tidal flows, that exceed 8 knots, could impact the device and its performance, but also how the O2’s wake downstream could impact the placing of other turbines as well as marine habitats.

Through this, the scientists provide new insights around the optimal placement of tidal stream turbines, while emphasising the importance of site-specific assessments at potential turbine sites to help bridge the gap between real-world measurements and computer simulations.

They also hope their approach can be used to address uncertainties surrounding interactions with the natural environment and marine habitats.

previous study by the lead authors found that a turbine wake generated a predictable foraging hotspot for nearby breeding seabirds, however if the turbine arrays are too tightly packed it could restrict the movement of some marine fauna.

In addition to seabirds, the authors encountered orcas travelling past the turbine during one of their drone surveys, demonstrating the importance of addressing this.  

The study, published in Nature Communications, was conducted by researchers from the Marine Biological Association (MBA), the University of Plymouth, and the University of the Highlands and Islands (UHI) Shetland.

Dr Lilian Lieber, Research Fellow at the MBA and the University of Plymouth, is the study’s lead author. She said: “Conducting oceanographic surveys in one of the world’s most powerful tidal streams, where currents can exceed 8 knots, is both exhilarating and challenging. Yet collecting data in these turbulent environments is crucial for addressing some of the complexities the tidal energy industry faces today. The optimal placement of these turbines in narrow channels fringed by islands is a complex endeavour, but our novel methods provided robust insights into these turbulent flows and wake signatures.”

Tidal power is seen as one of the more reliable sources of clean energy, with the tides – unlike wind and waves – being both regular and predictable.

The turbines, designed to harness tidal power near the sea surface, work much like windmills underwater and convert the kinetic energy of moving water into electricity. But with water being over 800 times denser than air, they generate more energy than wind turbines of the same size.

In future, it is envisaged there could be more installations around the UK, with previous research by those involved in the current study suggesting tidal stream energy could meet up to 11% of the UK’s annual electricity demands.

Shaun Fraser, Senior Scientist and Fisheries Lead from UHI Shetland, added “This study showcases the benefits of combining scientific expertise and deploying new technologies so that significant progress can be made in understanding dynamic tidal environments. With further development of marine renewable energy infrastructure in the Highlands and Islands region likely in the near future, this work is more relevant than ever to local industries and communities.”

Despite the promise of tidal energy, the sector still faces substantial challenges, including the costs of scaling up the technology, grid connection capacity, and ensuring turbines can continue to function in extremely turbulent currents.

The new study aimed to address some of those challenges by advancing field measurement techniques necessary to inform the long-term reliability and sustainable development of tidal technologies.

Alex Nimmo-Smith, Professor of Marine Science and Technology at the University of Plymouth and the study’s senior author, said: “Whether it is floating offshore wind farms in the Celtic Sea or tidal turbines off the coast of Scotland, we are going to see more offshore renewable energy platforms being installed all around the UK coastline over the coming decades. However, the natural conditions in the waters around the UK are incredibly varied and complex, something that it is impossible to fully replicate in controlled laboratory experiments or computer simulations. This study demonstrates a cost-effective means of countering that, and if we are to get the greatest benefits from the clean energy revolution, assessments that factor in real-world environmental conditions will be of critical importance.”
