Surgery past 65? Brain health screening can aid recovery

Feb 28, 2026

Before surgery, your doctor will order evaluations to identify any health problems that may need to be addressed before the procedure. This typically includes medical histories, laboratory tests and checking blood pressure, heart rate and temperature.

There’s one vital sign that is often not on the list, but is crucial for older adults: screening for mental and cognitive health.

“There is an overwhelming amount of evidence that presurgical brain health predicts complications after surgery,” said Catherine Price, Ph.D., a professor in the University of Florida College of Public Health and Health Professions Department of Clinical and Health Psychology and the UF College of Medicine Department of Anesthesiology. “For example, individuals with weaknesses in memory and attention and people with neurodegenerative diseases, such as Parkinson’s, have higher rates of confusion and memory complications that affect their recovery from surgery.”

Research by Price and others has shown that a patient’s cognitive, memory and mental health status before surgery is an excellent indicator of whether they will experience cognitive problems such as delirium, a common complications in older adults after surgery. Delirium, characterized by confusion, disorientation and impaired awareness, can lead to longer recovery times, increased dementia risk, higher mortality rates and health care costs.

Price founded and directs the University of Florida Perioperative Cognitive Anesthesia Network, or PeCAN, a first-of-its-kind, multidisciplinary program that seeks to identify older adults who may be at risk of developing cognitive problems after surgery so that clinicians can intervene.

In recent findings published in the journal Anesthesia and Analgesia, Price and her colleagues report on two years of PeCAN patient data. Of the thousands of patients over age 65 who received presurgical screening, 23% were found to have issues with their cognitive performance, yet only 2% of the patients screened had a previous note in their medical charts indicating they had a cognitive impairment.

“It’s so important to know when an individual has cognitive complications because that changes their care path,” Price said. “From medication to monitoring, the patient’s care is more complex for the perioperative team and family.”

For PeCAN patients identified as being at risk for postsurgery cognitive problems, Price and her team will share tailored recommendations with the patient’s care team before, during and after surgery. These may include more monitoring during anesthesia and medication adjustments, such as using medications for nausea and pain management less likely to contribute to delirium. The PeCAN team also might offer the surgical care team specific communication strategies. For example, health care providers should repeat information several times for patients who have trouble remembering new material and ask them to write it down.

Recently published research by Price and colleagues found PeCAN patients reported the focus on brain health improved confidence in their surgical team and care plan.

Health care systems are only starting to incorporate preoperative brain health teams like PeCAN. Until they are offered more frequently, Price offers a few steps anyone can take to help protect brain health, including a focus on reducing inflammation in the body prior to surgery. To help achieve this:

Optimize nutrition. Reduce your intake of added sugars and refined carbohydrates, like white bread.
Get good sleep. Improve sleep hygiene so you are well-rested. “Sleep is essential for the brain for a number of reasons,” Price said.
Reduce alcohol intake to limit inflammation and dehydration.
Pay attention to your medications. Follow your care team’s instructions. Enlist a family member or caregiver to help you keep tabs on what you’re taking, how much and how often.
Practice techniques to limit anxiety, such as visualization and deep breathing. The box breathing method is an easy one to remember: Breathe in slowly for four seconds. Hold your breath for four seconds. Slowly exhale for four seconds. Wait four seconds before inhaling again.

New AI tool matches students with high-impact internships

Finding the right internship can be an important step for students, but it’s not always clear which opportunities will lead to the strongest growth. To help solve that problem, University of Florida researchers have developed an AI-powered tool that helps students identify internships most likely to accelerate their technical and professional development. Unlike traditional recommendation engines, Pro-CaRE not only predicts which opportunities will lead to stronger outcomes, it also explains why each suggestion is a good fit. In testing data collected from the students, Pro-CaRE’s predictions proved highly accurate, accounting for more than 72% of the differences in learning gains among participants. While the pilot is being tested in engineering, the tool could be adopted for other disciplines. “Internships are one of the most critical parts of an engineering education, but students often struggle to know which experiences will actually help them grow,” said Jinnie Shin, assistant professor of research and evaluation methodology in the UF College of Education. “What makes Pro-CaRE unique is that it doesn’t just offer a list of options. It provides personalized recommendations backed by data and it tells students clearly why an opportunity is a good match for them.” Pro-CaRE creates matches by analyzing each student’s coursework, major, background and self-reported interest, confidence and self-efficacy in engineering skills. It then compares that profile with a carefully chosen set of similar peers to refine suggestions. The result is more precise guidance that adapts to students at different stages of their degree programs. “Students shouldn’t have to guess or hope that an internship will be worthwhile,” Shin said. “With Pro-CaRE, they can approach opportunities knowing they’re backed by evidence, whether the role is onsite, hybrid or remote and whether it’s at a startup or a Fortune 500 company.” The system is designed to work across a wide range of companies and contexts, giving students flexibility while ensuring their choices align with their personal and professional goals. Each recommendation comes with a clear “why this?” explanation, so students can make confident decisions and discuss options more effectively with advisors. Pro-CaRE was developed by a cross-disciplinary UF team combining expertise in education and engineering. Alongside Shin, the project’s co-principal investigators include Kent Crippen in the College of Education and Bruce Carroll in the Herbert Wertheim College of Engineering. The team is exploring external funding opportunities to expand the usage and test the efficacy on a larger scale. “Ultimately, our goal is to empower students to invest their time in experiences that will have the greatest impact,” Shin said. “Pro-CaRE bridges the gap between what students hope to gain and what internships can truly deliver.”

Using AI tools empowers and burdens users in online Q&A communities

Whether you’ve searched for cooking tips on Reddit, troubleshooted tech problems on community forums or asked questions on platforms like Quora, you’ve benefited from online help communities. These digital spaces rely on people across the world to contribute their knowledge for free, and have become an essential tool for solving problems and learning new skills. New research reveals that generative artificial intelligence tools like ChatGPT are creating a double-edge effect on users in these communities, simultaneously making them more helpful while potentially overwhelming them to the point of decreasing their responses. “On the positive side, AI helps users learn to write more organized and readable answers, leading to a noticeable increase in the number of responses,” explained Liangfei Qiu, Ph.D., study coauthor and PricewaterhouseCoopers Professor at the University of Florida Warrington College of Business. “However, when users rely too heavily on AI, the mental effort required to process and refine AI outputs can actually reduce participation. In other words, AI both empowers and burdens contributors: it enables more engagement and better readability, but too much reliance can slow people down.” The study examined Stack Overflow, one of the world’s largest question-and-answer coding platforms for computer programmers, to investigate the impact of generative AI on both the quality and quantity of user contributions. Qiu and his coauthor Guohou Shan of Northeastern University’s D’Amore-McKim School of Business measured the impact of AI on users’ number of answers generated per day, answer length and readability. Specifically, they found that users who used AI tools to generate their responses contributed almost 17% more answers per day compared to those who didn’t use AI. The answers generated with AI were both shorter by about 23% and easier to read. However, when people relied too heavily on AI tools, their participation decreased. Qiu and Shan noted that the additional cognitive burden associated with heavier AI usage negatively affected the impact on a user’s answer quality. For online help communities grappling with AI policies, this research provides valuable insight into how these policies can be updated in the current AI environment. While some communities, like Stack Overflow, have banned AI tools, this research suggests that a more nuanced approach could be a better solution. Instead of banning AI entirely, the researchers suggest striking a balance between allowing AI usage while promoting responsible and moderated use. This approach, they argue, would enable users to benefit from efficiency and learning opportunities, while not compromising quality content and user cognition. “For platform leaders, the takeaway is clear: AI can boost participation if thoughtfully integrated, but its cognitive demands must be managed to sustain long-term user contributions,” Qiu said.

CEOs 5 times more likely to survive fraud than a personal scandal

If the CEO of Astronomer had overseen tax fraud instead of being caught on a kiss cam cuddling his HR chief in an extramarital affair, he might still have a job. That’s because, according to a new study, CEOs are five times more likely to be fired for personal misconduct than for overseeing financial fraud. “For financial fraud, the CEO can easily say, ‘Hey, it wasn’t me,’” said Aaron Hill, Ph.D., an associate professor in the University of Florida Warrington College of Business who led the study. “With personal misconduct, there’s no excuse.” The research, forthcoming in Strategic Organization, examined 59 cases of personal misconduct and compared them with more than 300 financial scandals at publicly traded companies between 1997 and 2020. The personal cases included inappropriate relationships, drug or alcohol incidents, domestic violence, falsifying credentials and derogatory speech. Hill and his colleagues found that boards move decisively when a CEO’s private behavior becomes public. By contrast, financial misconduct — such as accounting restatements that can wipe out billions in shareholder value — often leaves room for a chief executive to deflect blame onto others in the organization. Recent company performance influenced how boards responded, to a point. A CEO whose company was thriving could often survive a financial scandal because directors had both plausible deniability and a strong incentive not to disrupt success. But good numbers offered little protection when the problem was personal behavior. For example, McDonald’s ousted Steve Easterbrook in 2019 over a consensual relationship with a subordinate, even though the company’s stock price had doubled under his leadership. Hewlett-Packard similarly dismissed CEO Mark Hurd after harassment allegations despite his reputation for turning the firm around. “Even strong performance can’t erase certain kinds of misconduct,” Hill said. “There are some things you just can’t excuse.” The study also uncovered how scandals influenced succession decisions. When personal misconduct led to a firing, boards were more likely to promote an insider, signaling that the problem lay with one person rather than the culture of the company. Financial scandals, on the other hand, often prompted boards to recruit outsiders as a way of reassuring markets that the firm was serious about change. “It’s a signaling move,” Hill said. “Bring in an outsider after fraud, and the market reacts positively. Stick with an insider after a personal scandal, and it says the organization itself is sound.” The researchers argue that these choices reveal how boards balance their fiduciary duty with the reputational risks of scandal. While dismissing a CEO can serve as a public relations reset, Hill emphasized that it is almost always a financially motivated calculation. “Boards are supposed to look out for the company and its shareholders,” he said. “But when they decide to keep a CEO after misconduct, I think it sends the wrong message — to employees, to investors and to the public.”
