Beyond the Machine: How Radiology’s Sustainability Focus is Shifting to the Supply Chain

For decades, healthcare sustainability efforts have centered on energy consumption – optimizing MRI machine usage, switching to LED lighting, and implementing smart building technologies. However, a groundbreaking fresh study published in the Journal of the American College of Radiology (JACR) reveals a surprising truth: in diagnostic ultrasound, the biggest carbon footprint doesn’t come from the equipment itself, but from the disposable supplies and, surprisingly, the linens used in each procedure. This finding is prompting a major re-evaluation of sustainability strategies within radiology departments and beyond.

The Unexpected Culprit: Linens and Disposables

The study, titled “Harmonizing Diagnostic Ultrasound Practice with Environmental Sustainability: A Life Cycle Assessment of Diagnostic Ultrasound in a Single Adult University Hospital,” found that linens account for 35% and single-use supplies 34% of ultrasound’s greenhouse gas emissions. In contrast, the production (7%) and energy use (3%) of the ultrasound equipment itself were comparatively minor contributors. This challenges the conventional wisdom that focusing solely on energy efficiency is the key to reducing radiology’s environmental impact.

Katherine Frederick-Dyer, MD, Director of Body MRI at Vanderbilt Health and lead author of the study, explains, “Although linens and disposable supplies were the greatest contributors to the carbon footprint of ultrasound, strategies to optimize their use can be implemented across radiology department modalities for an even greater impact.”

A Systems-Based Approach to Sustainability

This shift in understanding necessitates a more holistic, “systems-based” approach to sustainability in radiology. It’s no longer enough to simply purchase energy-efficient equipment. Departments must now scrutinize their entire supply chain, from the sourcing of materials to the disposal of waste.

Florence X. Doo, MD, MA, Director of Innovation at the University of Maryland Medical Intelligence Imaging Center, and guest editor of the JACR’s April Focus on Sustainability issue, emphasizes this point. “We need to think more about how our technological processes, from end to end, contribute to health care emissions…most of the technology in a health system lives with us in radiology—MRI machines, CT machines and now AI.”

The Rise of Eco-Friendly Alternatives

The study encourages the adoption of more sustainable materials. This includes exploring sustainably sourced organic cotton for linens and seeking compostable alternatives to traditional plastic products. Radiology departments are beginning to investigate options like reusable probe covers and sterilization methods that reduce the need for single-use items.

Beyond ultrasound, this principle applies across all imaging modalities. Consider the environmental impact of contrast agents, the packaging of supplies, and even the transportation of materials to the hospital.

AI and Sustainability: A Complex Relationship

While artificial intelligence (AI) is often touted as a tool for improving efficiency and reducing waste in healthcare, its environmental impact is also coming under scrutiny. The Radiology Business reports that practices tied to private equity and hospitals charge significantly more, potentially indicating increased resource consumption. The American College of Radiology (ACR) projects a five-fold growth in FDA approvals of AI imaging products by 2035, raising questions about the energy demands and resource requirements of these technologies.

The Future of Sustainable Radiology

The future of radiology sustainability isn’t just about reducing environmental impact; it’s also about operational efficiency and quality improvement. As Dr. Doo notes, “Sustainability is starting to be framed more as a quality improvement and operational efficiency problem. We need to do this right to reduce waste, improve our energy and optimize our workflow so we can do better as radiologists.”

This means embracing data-driven approaches to identify areas for improvement, collaborating with suppliers to source more sustainable products, and fostering a culture of environmental responsibility within radiology departments.

FAQ: Radiology and Sustainability

Alzheimer’s Treatment: A New Combination Approach Offers Hope

A groundbreaking study from the University of Waterloo reveals a promising new strategy in the fight against Alzheimer’s disease. Researchers have discovered that combining existing Alzheimer’s medications with naturally occurring modest molecules – found in everyday foods like grapes, berries, peanuts, and turmeric – could be a safer and more effective treatment pathway. The findings, published in ACS Chemical Neuroscience, suggest a potential shift towards combination therapies for this devastating condition.

The Problem with Current Alzheimer’s Treatments

Alzheimer’s disease, the leading cause of dementia, currently affects nearly 750,000 people in Canada, with projections estimating one million cases by 2030. Whereas current medications can assist manage symptoms, there is no cure. Emerging anti-amyloid antibody therapies show promise in slowing the disease’s progression, but carry significant risks, including potentially fatal brain swelling and bleeding.

How the New Combination Works

The core issue in Alzheimer’s is the buildup of toxic amyloid proteins in the brain. The University of Waterloo team combined amyloid-destroying small molecules – specifically resveratrol and curcumin – with existing anti-amyloid antibodies. This combination effectively neutralized the clumping of proteins, leading to improved outcomes in laboratory settings. Dr. Praveen Nekkar Rao, a professor at Waterloo’s School of Pharmacy, explained that resveratrol and curcumin are known to block amyloid buildup, and combining them with antibodies could allow for lower antibody doses, potentially reducing dangerous side effects.

Inspired by Chemotherapy: The Power of Combination Therapy

Researchers deliberately explored a combination therapy approach, drawing inspiration from cancer treatment protocols. “I was inspired by chemotherapy, which involves taking multiple medications for effective treatment,” said Dr. Nekkar Rao. “Alzheimer’s is a complex disease, but there are very few combination therapy approaches. Our results show that the way forward is definitely combination therapy.” The study focused on resveratrol and curcumin due to their established ability to reduce amyloid buildup and inflammation.

Beyond the Lab: What’s Next for Alzheimer’s Research?

While the study’s results are encouraging, researchers caution against self-treating with resveratrol or curcumin supplements. Consuming sufficient quantities of these compounds to impact the brain would require unsafe levels of intake. The next phase of research will concentrate on developing next-generation drugs designed to effectively reach the brain, interact favorably with amyloid proteins, and seamlessly integrate with antibody treatments.

The Future of Neurodegenerative Disease Treatment

This research aligns with a growing trend in neuroscience: exploring the potential of naturally derived compounds to combat neurodegenerative diseases. Recent studies suggest vitamin K analogs may also hold promise for reversing these conditions. The focus is shifting from single-target drugs to multi-faceted approaches that address the complex interplay of factors contributing to diseases like Alzheimer’s.

Sleep’s Silent Signals: How Brainwave Analysis Could Revolutionize Dementia Prediction

For decades, the looming threat of dementia has cast a shadow over aging populations worldwide. Now, a groundbreaking approach leveraging the power of sleep electroencephalography (EEG) is offering a new beacon of hope. Recent research indicates that subtle patterns in brainwaves during sleep can predict the risk of developing dementia years before symptoms manifest, potentially opening doors to earlier intervention and improved patient outcomes.

Decoding the Brain Age Index (BAI)

A study published in JAMA Network Open, involving over 7,100 adults, revealed a compelling correlation: for every 10-year increase in Brain Age Index (BAI) – calculated from sleep EEG data – the risk of dementia rose by approximately 39%. This isn’t simply about sleep quality, but rather the intricate details of brainwave activity during sleep. Researchers are using machine learning models to analyze the speed and structure of these waves across different sleep stages, effectively estimating a “brain age” that may differ from a person’s chronological age.

The BAI is determined by comparing the age predicted by the AI based on EEG data to the individual’s actual age. A higher BAI suggests faster brain aging, and, crucially, this metric proved to be a unique predictor, remaining significant even after accounting for factors like age, sex, lifestyle, and genetic predisposition (specifically, apolipoprotein E ε4 status).

Beyond Sleep Quality: A New Biomarker Emerges

Sleep disturbance has long been recognized as a potential risk factor for dementia, but traditional sleep measures – total sleep time, sleep efficiency – have yielded inconsistent results. The EEG-based BAI offers a more nuanced and potentially more accurate assessment. Instead of focusing on how much someone sleeps, it delves into the characteristics of their brain activity although asleep.

This approach repurposes existing EEG technology, making it potentially more accessible than other advanced neuroimaging techniques. The machine learning models are trained on data from individuals without known brain conditions, allowing them to establish a baseline of healthy brain activity and identify deviations that may signal increased risk.

The Promise of Early Detection and Intervention

The implications of this research are significant. Early detection of dementia risk allows for proactive lifestyle modifications, such as increased physical exercise, cognitive stimulation, and dietary changes, which may help delay the onset of symptoms. It could accelerate the development and testing of new therapies aimed at slowing or preventing neurodegeneration.

The study’s findings were consistent across diverse populations, applying equally to men and women, and individuals both younger and older than 70, suggesting broad applicability. Though, researchers emphasize the need for further investigation to validate the BAI as a reliable biomarker across different populations and in individuals with other health conditions.

Future Trends: Personalized Risk Assessment and Targeted Therapies

The development of the EEG-based BAI is just the beginning. Several exciting trends are emerging in the field of dementia prediction and prevention:

• Multi-Modal Biomarker Integration: Combining the BAI with other biomarkers – blood tests for specific proteins, genetic screening, and advanced neuroimaging – could create a more comprehensive and accurate risk profile.
• Personalized Sleep Interventions: Tailoring sleep interventions based on individual brainwave patterns could potentially gradual down brain aging and reduce dementia risk.
• AI-Powered Drug Discovery: Machine learning algorithms are being used to identify potential drug candidates that target the underlying mechanisms of neurodegeneration.
• Digital Biomarkers and Wearable Technology: The use of wearable devices to continuously monitor sleep and brain activity could provide a wealth of data for personalized risk assessment and early detection.

The convergence of these technologies promises a future where dementia is not an inevitable consequence of aging, but a manageable condition that can be prevented or delayed through early detection and targeted interventions.

Frequently Asked Questions

The Unfulfilled Life: How Psychological Needs Drive Risky Alcohol Employ – And What We Can Do About It

New research from the University of Georgia highlights a critical link between our fundamental psychological needs and our relationship with alcohol. The findings, published in Psychology of Addictive Behaviors, suggest that individuals struggling with feelings of autonomy, competence and connection are more likely to engage in risky drinking behaviors.

The Core Needs: Autonomy, Competence, and Connection

The study identified three key psychological needs as central to responsible alcohol consumption. Autonomy refers to feeling a sense of choice and freedom. Competence is the belief in one’s ability to do things well. Connection represents feeling cared for and supported by others. When these needs are unmet, individuals may turn to alcohol as a coping mechanism, leading to increased risk.

Researchers found that across three studies, participants who reported a stronger sense of these needs tended to drink less, consume alcohol more slowly, and prioritize safety measures like using a designated driver. Conversely, those feeling unfulfilled were more prone to drinking to excess, experiencing blackouts, and acting impulsively.

Age Matters: A Shifting Focus with Time

Even as the initial studies focused on college students, the research expanded to include adults in their 40s and 50s. This revealed a nuanced trend: the impact of unmet psychological needs on alcohol severity became more pronounced with age. Rather than focusing on specific safety behaviors, the study tracked the overall level of alcohol consumption over a two-year period. The results showed a direct correlation – as alcohol use increased, feelings of frustration and unmet needs followed suit.

This suggests that while younger adults might exhibit risky behaviors in specific instances, older adults experiencing chronic psychological distress are at greater risk for sustained, problematic alcohol use.

Beyond Alcohol: A Broader Pattern of Addictive Behaviors

The implications of this research extend beyond alcohol. Previous studies have indicated that unmet psychological needs can contribute to other unhealthy behaviors, including smoking and unhealthy eating. This suggests a common underlying mechanism driving a range of addictive tendencies.

Researchers emphasize that addressing these fundamental needs is crucial for overall well-being and can serve as a preventative measure against various forms of addiction.

What Can Be Done? Fostering Psychological Well-being

The research points to proactive steps individuals can take to cultivate a healthier relationship with alcohol and improve their overall quality of life. These include:

• Self-Reflection: Regularly assess your sense of autonomy, competence, and connection. Are you making choices aligned with your values? Do you feel confident in your abilities? Do you have strong, supportive relationships?
• Prioritize Supportive Relationships: Nurture connections with people who care about you and provide a sense of belonging.
• Pursue Meaningful Activities: Engage in activities that allow you to feel competent and capable. This could involve hobbies, work, or volunteering.
• Make Conscious Choices: Actively seek opportunities to exercise your autonomy and make decisions that reflect your own desires and values.

“People are inclined to flourish overall when those psychological needs are met,” explains Dylan Richards, assistant professor in the Franklin College of Arts and Sciences’ department of psychology at the University of Georgia. “They are more positive and experience more internalized motivation for doing things that are healthy for them, like drinking responsibly.”

Future Trends: Personalized Interventions and Early Detection

Looking ahead, the field of addiction treatment is likely to see a growing emphasis on personalized interventions that address underlying psychological needs. Instead of solely focusing on symptom management, clinicians may increasingly incorporate strategies to foster autonomy, competence, and connection.

Advances in technology could similarly play a role in early detection. Wearable sensors and mobile apps could potentially monitor physiological indicators of stress and psychological distress, alerting individuals to potential risks before they escalate into problematic behaviors. AI-powered chatbots could provide personalized support and guidance, helping individuals identify and address unmet needs.

The research also suggests a potential for preventative programs targeting young adults, focusing on building resilience and fostering psychological well-being before unhealthy coping mechanisms develop.

FAQ

Q: What are the three psychological needs identified in the study?
A: Autonomy (feeling a sense of choice), competence (feeling capable), and connection (feeling cared for).

Q: Does this research apply to all types of addiction?
A: While the study focused on alcohol, the underlying principle of unmet psychological needs contributing to addictive behaviors likely extends to other substances and behaviors.

Q: How can I assess my own psychological needs?

The Rising Tide of Colorectal Cancer in Younger Adults: A New Treatment Paradigm

Colon cancer, the third most common cancer in the United States, is increasingly affecting younger individuals. While screening programs have improved detection rates in older adults, advancements in treatment have been limited – until now. New research is offering a significant breakthrough for a specific subset of patients with stage 3 colon cancer.

Immunotherapy Shows Promise for dMMR Stage 3 Colon Cancer

A recent study led by Mayo Clinic Comprehensive Cancer Center revealed that adding immunotherapy to standard chemotherapy after surgery for stage 3 colon cancer patients with deficient DNA mismatch repair (dMMR) resulted in a 50% reduction in cancer recurrence and mortality. This represents a major shift in treatment protocols and offers renewed hope for those diagnosed with this aggressive form of the disease.

Approximately 15% of colon cancer patients exhibit dMMR, meaning their tumors have a reduced ability to correct DNA errors. Historically, these tumors have shown limited response to chemotherapy alone. The multicenter study, presented at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting, demonstrates the power of combining immunotherapy with existing treatments.

Understanding dMMR and the Role of Immunotherapy

dMMR tumors accumulate a high number of mutations, making them “visible” to the immune system. However, cancer cells often develop mechanisms to evade immune detection. Immunotherapy, specifically immune checkpoint inhibitors like atezolizumab, works by releasing the brakes on the immune system, allowing it to recognize and destroy cancer cells.

Researchers previously observed a striking increase in inflammatory cells, including immune cells, within dMMR tumors. This finding provided the scientific basis for exploring immune checkpoint inhibitors as a potential treatment strategy. The clinical trial involved 712 patients with surgically removed stage 3 dMMR colon cancer and cancer cells in their lymph nodes. Patients received either chemotherapy plus immunotherapy (atezolizumab) for six months, followed by immunotherapy alone for another six months, or chemotherapy alone.

A New Standard of Care and Updated Guidelines

The results of the clinical trial have led to a change in the standard of care for stage 3 dMMR colon cancer. The National Comprehensive Cancer Network (NCCN) has updated its guidelines to include the combination of atezolizumab and chemotherapy as a recommended treatment option. These updated guidelines also extend to high-risk stage 2 colon cancer cases.

The study also included patients with Lynch syndrome, a hereditary condition that predisposes individuals to colon cancer and is often associated with dMMR tumors. This suggests the treatment benefits extend to those with a genetic predisposition to the disease.

Future Trends in Colorectal Cancer Treatment

The success of immunotherapy in dMMR colon cancer is paving the way for further research and potential advancements in the field. Several key trends are emerging:

• Personalized Immunotherapy: Researchers are exploring ways to tailor immunotherapy treatments to individual patients based on their tumor’s specific genetic makeup and immune profile.
• Early Detection Biomarkers: Identifying biomarkers that can detect dMMR or other predictive factors in earlier stages of the disease will be crucial for proactive treatment.
• Combination Therapies: Combining immunotherapy with other treatments, such as targeted therapies or radiation, may further enhance treatment efficacy.
• Focus on the Microbiome: The gut microbiome plays a significant role in immune function. Research is investigating how manipulating the microbiome could improve immunotherapy response.

FAQ

Q: What is dMMR?
A: Deficient DNA mismatch repair is a condition where the body has trouble correcting errors in DNA, leading to a higher mutation rate in cancer cells.

Q: Who is eligible for this new treatment?
A: Patients diagnosed with stage 3 colon cancer who have dMMR tumors are eligible for the combination of atezolizumab and chemotherapy.

Q: What are the potential side effects of immunotherapy?
A: Immunotherapy can cause side effects as it stimulates the immune system. These can range from mild flu-like symptoms to more serious autoimmune reactions.

Q: Is this treatment available for all stages of colon cancer?
A: Currently, the NCCN guidelines recommend this treatment for stage 3 dMMR colon cancer and high-risk stage 2 colon cancer.

Q: What is Lynch syndrome?
A: Lynch syndrome is the most common form of hereditary colon cancer, often associated with dMMR tumors and diagnosed at a younger age.

Did you know? Colorectal cancer rates are rising in younger adults, with 1 in 5 diagnoses now occurring in individuals under the age of 55.

A 2024 Recent York Times investigation, cited in the lawsuits, found limited apply for privately stored cord blood.

What is Cord Blood Banking?

Cord blood is the blood that remains in the umbilical cord and placenta after a baby is born. It’s a rich source of stem cells, which have the potential to develop into different types of cells in the body. Families can choose to donate cord blood to a public bank, making it available for anyone in need, or store it privately for potential use by their own family. Private storage involves significant upfront and annual fees.

Limited Medical Applications Today

Despite the promise, the practical applications of privately stored cord blood are currently limited. Advances in adult stem cell technology have provided alternative options for many treatments. The New York Times investigation revealed that only 19 transplants utilizing a child’s stored cord blood have been reported since 2010. Most uses remain within the realm of hematopoietic stem cell transplants – treatments for blood and immune system disorders, certain cancers, and metabolic diseases.

Concerns Beyond Efficacy: Quality and Contamination

The lawsuits also raise concerns about the quality and safety of stored samples. Some samples may be unusable due to low cell counts or contamination. Federal inspectors have reportedly found signs of bacterial growth at CBR’s facility, further fueling these concerns. Arizona’s lawsuit specifically alleges that CBR “conceals serious contamination concerns and risks from consumers.”

The Emotional Decision and Financial Burden

For many parents, the decision to bank cord blood is an emotional one, driven by a desire to do everything possible to protect their child’s future health. Arizona Attorney General Kris Mayes, who stored her daughter’s cord blood 13 years ago, shared her personal experience, highlighting the vulnerability of new parents to such marketing claims. The cost of private cord blood banking can be substantial, involving thousands of dollars upfront and ongoing storage fees.

What’s Next for CBR and the Industry?

CBR has contested the Arizona case, pointing to contract language stating “There is no guarantee or assurance regarding success.” However, a judge rejected the company’s attempt to dismiss the lawsuit. The outcome of these legal battles could have significant implications for the cord blood banking industry, potentially leading to stricter regulations and increased transparency.

Future Trends in Cord Blood and Tissue Banking

Despite the current scrutiny, research into the potential of cord blood and tissue continues. Several trends suggest a possible evolution of the industry:

Beyond the Delivery Room: Why Longer Monitoring is Crucial for Maternal Health

For decades, maternal health monitoring has largely focused on the period around labor and delivery. However, groundbreaking research is revealing a critical blind spot: a significant number of severe pregnancy complications occur before and after childbirth. A recent study published in the Canadian Medical Association Journal demonstrates that extending monitoring from conception to six weeks postpartum identifies over 40% more cases of severe maternal morbidity (SMM) than traditional methods.

The Rising Tide of Severe Maternal Morbidity

Severe maternal morbidity encompasses life-threatening complications during pregnancy, labor, and the postpartum period. These can include severe hemorrhage, pre-eclampsia, sepsis, and acute appendicitis. The Ontario-based study, analyzing nearly 1.1 million births between 2012 and 2021, found an SMM rate of 27.24 per 1,000 births – translating to almost 10,000 Canadian patients experiencing these complications annually.

This isn’t just a Canadian issue. Globally, rates of SMM are increasing, driven by factors like rising maternal age, increasing rates of pre-existing conditions like diabetes, and disparities in access to care. The study reinforces calls for a standardized national framework for collecting and tracking maternal health data.

Shifting the Focus: Prenatal and Postpartum Risks

Traditionally, the most intense monitoring occurs during labor and delivery. However, the data paints a different picture. Nearly half of maternal deaths in Ontario occur outside of this window – 47% prenatally and 46% postpartum. The research highlights that 16% of SMM events occur during the prenatal period, 55% during labor and delivery, and 29% in the six-week postpartum period.

Specific complications tend to cluster in different phases. Acute appendicitis and sepsis are more common before birth, while sepsis is also a leading cause of SMM in the postpartum period. Risk factors also vary; younger mothers (15-24 years) are more prone to prenatal complications, while older mothers and those experiencing their first pregnancy face higher risks during and after delivery.

Emergency Departments: A Key Point of Contact

The study also revealed a surprising trend: many women experiencing SMM first seek facilitate in emergency departments, rather than from their obstetrician. This underscores the require for better communication and coordination between emergency care, primary care, maternity care teams, and postpartum follow-up services. As Dr. Giulia Muraca, a lead researcher, explains, “Severe maternal complications aren’t just a delivery room issue—they occur across pregnancy and after birth.”

Factors Increasing Risk

Several factors are consistently associated with increased risk of SMM, including:

• First pregnancy
• Maternal race
• Pre-existing medical conditions (particularly Type 1 diabetes, which shows a strong link to prenatal SMM)
• Multiple pregnancies
• Immigrant status
• Low income
• Rural or remote residence
• Substance use during pregnancy
• History of assault

Future Trends in Maternal Care

The findings suggest several key areas for future development in maternal healthcare:

Enhanced Postpartum Monitoring

The most immediate need is for expanded postpartum monitoring. This could include remote monitoring of vital signs like heart rate and blood pressure for high-risk individuals, as well as increased access to primary care and ambulatory obstetrical care.

Improved Data Collection and Surveillance

A standardized national framework for collecting and analyzing maternal morbidity and mortality data is essential. This will allow for better identification of trends, risk factors, and areas for improvement.

Integrated Care Pathways

Breaking down silos between different healthcare settings – emergency departments, primary care, and maternity units – is crucial. Integrated care pathways can ensure seamless communication and coordinated care for pregnant and postpartum individuals.

Addressing Social Determinants of Health

Recognizing and addressing the social determinants of health – such as income, housing, and access to transportation – is vital for reducing disparities in maternal health outcomes.

FAQ: Maternal Health Monitoring

Q: What is Severe Maternal Morbidity (SMM)?
A: SMM refers to complications during pregnancy, labor, or the postpartum period that can result in death, extended hospitalization, or long-term disability.

Q: Why is postpartum monitoring so important?
A: A significant number of SMM events occur in the weeks following childbirth, and these complications can have long-term health consequences.

Q: What can be done to reduce the risk of SMM?
A: Improved access to prenatal and postpartum care, better data collection, and addressing social determinants of health are all important steps.

Q: Where can I find more information about maternal health?
A: The Canadian Medical Association Journal and the World Health Organization are excellent resources.

Did you know? Type 1 diabetes is strongly associated with severe maternal complications occurring before labor.

This research underscores a fundamental shift in how we approach maternal healthcare. Moving beyond a delivery-focused model to one that encompasses the entire continuum of care – from conception to six weeks postpartum and beyond – is essential for protecting the health and well-being of mothers and families.

Pro Tip: Don’t hesitate to discuss any concerns you have with your healthcare provider, even if they seem minor. Early detection and intervention can significantly improve outcomes.
