    Didn’t Hit Your 2025 Savings Goals? Start Fresh With These Tools

    The new year is upon us and if you’re looking to make progress with your money in 2026, why wait until January 1 to start strategizing?

    Bankrate’s Annual Emergency Savings report found that 8 in 10 Americans did not increase their emergency savings in 2025. In fact, 19% of respondents actually have less emergency savings now than they did at the start of the year.

    If you’ve dipped into your savings this year — or just missed the mark on a big savings goal — here are some tips and tools to help you build up a stash of cash in 2026.

    Get rid of expenses you don’t need anymore

    Saving more money generally starts with auditing where how much you’re earning versus how much you’re spending and cutting out expenses for things that you don’t need or don’t use anymore. Many times, the culprit is unused or forgotten subscriptions and memberships.

    Expense tracking platforms like Monarch Money and Empower help you categorize your expenses and automatically track transactions so you know exactly where your money is going. Monarch offers a 7-day free trial but the Empower app is completely free unless you decide to use the investing services.

  • ICYMI: Highlights From ASH 2025

    ICYMI: Highlights From ASH 2025

    The 67th American Society of Hematology (ASH) annual meeting showcased a shift in hematology, prioritizing precision and quality of life, and signaling a move toward more accessible, “off-the-shelf” cancer care.

    Key highlights included the debut of in vivo chimeric antigen receptor (CAR) T-cell therapy and data supporting a chemotherapy-free frontline regimen for acute myeloid leukemia (AML).

    Find the 5 most-read articles from ASH below, and check out all of our coverage from the conference.

    5. In CLL, Fixed-Duration Venetoclax Combos Are Equal to Continuous Ibrutinib in Head-to-Head Comparison

    The phase 3 CLL17 trial provided the first head-to-head evidence that fixed-duration venetoclax combinations are clinically noninferior to continuous ibrutinib for patients with chronic lymphocytic leukemia (CLL). After 3 years, progression-free survival rates were nearly identical across all arms, but the venetoclax-based regimens achieved significantly higher complete response rates compared with indefinite monotherapy.

    “The aim here is to combine and produce deep remissions and thereby allow patients to get off therapy while still remaining in remission,” said Othman Al-Sawaf, MD, PhD, of University Hospital of Cologne.

    These results highlight a major shift toward time-limited treatment, allowing patients to enjoy multiyear “treatment-free intervals” that reduce long-term toxicities, such as cardiac events, while potentially lowering overall health care costs.

    4. EPCORE FL-1: Adding Epcoritamab to R2 Delivers “New Benchmark” in Second-Line Follicular Lymphoma

    The phase 3 EPCORE FL-1 trial has established a “new benchmark” for treating relapsed follicular lymphoma by adding the bispecific antibody epcoritamab to the standard regimen of rituximab (Rituxan) plus lenalidomide (Revlimid), also known as R2. This chemotherapy-free triplet delivered a 79% progression-free survival advantage over R2 alone, with an overall response rate of 95% and durable outcomes across both high- and low-risk patient subgroups. Designed as a fixed-duration, 12-cycle therapy, the regimen is optimized for outpatient administration, allowing patients to receive highly potent, “off-the-shelf” care in their own communities shortly after their first relapse.

    Lorenzo Falchi, MD, a lymphoma specialist at Memorial Sloan Kettering Cancer Center, who presented the results, said the triplet “sets a new benchmark as a standard of care.”

    3. 52-Week VERIFY Data Show Rusfertide Brings Sustained Responses in PV

    The 52-week VERIFY trial results for rusfertide demonstrate a significant shift in polycythemia vera (PV) management by mimicking the natural hormone hepcidin to regulate red blood cell production. Patients in the study achieved sustained hematocrit control and a dramatic reduction in phlebotomy requirements, with more than 77% of crossover participants successfully avoiding the painful procedure during the assessment window.

    Long-term data from the THRIVE extension reinforce these findings, highlighting a 13-fold reduction in phlebotomy rates over 4 years alongside significant improvements in patient-reported fatigue.

    “The 32-week VERIFY primary results were already promising, and this deeper understanding of the durability of response with rusfertide is critical to inform clinical decision-making for polycythemia vera,” said Andrew T. Kuykendall, MD, an associate member in the Department of Hematology at Moffitt Cancer Center.

    2. Azacitidine/Venetoclax Combo Data Challenge Chemo in Fit Patients With AML

    The PARADIGM trial presented at the plenary session suggests that the combination of azacitidine and venetoclax could replace intensive chemotherapy as the frontline treatment for fit patients with AML. Patients on the combo compared with patients on the traditional “7+3” chemotherapy regimen achieved significantly higher overall response rates (88% vs 62%) and improved event-free survival.

    The combo also enabled a higher percentage of patients to proceed to lifesaving transplants and drastically reduced hospital stays and intensive care unit admissions, offering patients a better quality of life and a much lower risk of early mortality than conventional induction.

    1. In Vivo CAR T Takes Center Stage, With Results Shared for 4 MRD-Negative Patients

    Researchers debuted transformative phase 1 data on KLN-1010, a pioneering in vivo CAR T-cell therapy that generates cancer-fighting cells directly inside the patient’s body. In the initial study, all 4 patients with relapsed or refractory multiple myeloma achieved minimal residual disease–negative status within just 1 month, with the longest response reaching 4 months. This “off-the-shelf” approach eliminates the need for weeks of external manufacturing and toxic lymphodepleting chemotherapy, offering a significantly improved safety profile and the potential to improve access to one-and-done cancer treatments. However, the results are still early, and only data on 3 of the 4 patients were presented at ASH during the late-breaking session.

    “It’s very early. They’re only reporting on 3 patients, so we still have a lot more to learn,” Michael Rosenzweig, MD, MS, chief of the Division of Multiple Myeloma, City of Hope, said in an interview. “But it’s definitely an exciting abstract that’s beginning, at least, to offer proof of principle that it’s possible to do this with some efficacy.”

  • Remembering Lou Gerstner

    Remembering Lou Gerstner

    The following is the text of an email sent today to all IBM employees by Chairman and CEO Arvind Krishna:

    IBMers, 

    I am saddened to share that Lou Gerstner, IBM’s Chairman and CEO from 1993 to 2002, passed away yesterday.

    Lou arrived at IBM at a moment when the company’s future was genuinely uncertain. The industry was changing rapidly, our business was under pressure, and there was serious debate about whether IBM should even remain whole. His leadership during that period reshaped the company. Not by looking backward, but by focusing relentlessly on what our clients would need next. 

    One of Lou’s earliest signals as CEO has become part of IBM lore. Early on, he stopped a long internal presentation and said, simply, “Let’s just talk.” The message was clear: less inward focus, more real discussion, and much closer attention to customers. That mindset would define his tenure. 

    Lou believed one of IBM’s central problems was that we had become optimized around our own processes, debates, and structures rather than around client outcomes. As he later put it, the company had lost sight of a basic truth of business: understanding the customer and delivering what the customer actually values. 

    That insight drove real change. Meetings became more direct. Decisions were grounded more in facts and client impact than in hierarchy or tradition. Innovation mattered if it could translate into something clients would come to rely on. Execution in the quarter and the year mattered, but always in service of longer-term relevance. 

    Lou made what may have been the most consequential decision in IBM’s modern history: to keep IBM together. At the time, the company was organized into many separate businesses, each pursuing its own path. Lou understood that clients didn’t want fragmented technology—they wanted integrated solutions. That conviction shaped IBM’s evolution and reestablished our relevance for many of the world’s largest enterprises. 

    Lou also understood that strategy alone would not be enough. He believed lasting change required a shift in culture—in how people behave when no one is watching. What mattered was what IBMers valued, how honestly they confronted reality, and how willing they were to challenge themselves and each other. Rather than discard IBM’s long-standing values, he pushed the company to renew them to meet the demands of a very different era. 

    I have my own memory of Lou from the mid-1990s, at a small town hall with a few hundred people. What stood out was his intensity and focus. He had an ability to hold the short term and the long term in his head at the same time. He pushed hard on delivery, but he was equally focused on innovation: doing work that clients would remember, not just consume. 

    Lou stayed engaged with IBM long after his tenure ended. From my first days as CEO, he was generous with advice—but always careful in how he gave it. He would offer perspective, then say, “I’ve been gone a long time—I’m here if you need me.” He listened closely to what others were saying about IBM and reflected it back candidly.  

    That neutral, experienced voice mattered to me, and I was fortunate to learn from Lou on a regular basis. 

    Lou was direct. He expected preparation. He challenged assumptions. But he was deeply committed to building a company that could adapt—culturally as much as strategically—without losing its core values. 

    Lou’s impact extended well beyond IBM. Before joining the company, he had already built an extraordinary career—becoming one of the youngest partners at McKinsey & Company, later serving as president of American Express and CEO of RJR Nabisco. After IBM, he went on to chair The Carlyle Group and devoted significant time and resources to philanthropy, particularly in education and biomedical research. A native of Long Island, NY, Lou earned his undergraduate degree from Dartmouth and an MBA from Harvard, and he remained deeply devoted to his family throughout his life. Lou was preceded in death by his son Louis Gerstner III. 

    We will hold a celebration in the new year to reflect on Lou’s legacy and what his leadership enabled at IBM. 

    My thoughts are with Lou’s wife Robin, his daughter Elizabeth, his grandchildren and extended family, as well as his many friends, colleagues, and people around the world who were shaped by his leadership and his work.

  • Holiday season puts focus on growing reality of family estrangement

    Holiday season puts focus on growing reality of family estrangement

    ‘It’s important for these people to feel like they have somewhere to go and that they are supported, because that could be any of us,’ says a CMHA psychotherapist

    With the holiday season in swing, the Canadian Mental Health Association (CMHA) North Bay and District is drawing attention to a growing but often hidden reality: family estrangement.

    While the holidays are widely portrayed as a time of togetherness, for many people, they can instead amplify feelings of loss, loneliness, and disconnection.

    CMHA officials say those emotions are becoming more common as more Canadians distance themselves from family relationships that feel unsafe or unhealthy.

    CMHA North Bay and District is shining a light on why estrangement is on the rise, how it affects mental health, and how to support people struggling during the holidays.

    Estrangement refers to the intentional distancing or separation from family members or other significant relationships.

    While Canadian data is limited, a Cornell University study in the United States found that 27 per cent of adults reported being estranged from at least one family member, according to CMHA officials. Mental health professionals in Canada say they are seeing similar trends.

    The issue, they say, often becomes more visible during the holiday season, when social expectations around family are heightened.

    “The holiday season can be especially challenging for people experiencing estrangement,” said Mary Davis, CEO of CMHA North Bay and District.

    “Many people find the holiday season to be a stark reminder of what’s missing, including loved ones and meaningful relationships.”

    CMHA North Bay and District Health Promotion Coordinator Malinda Hirvilammi says estrangement is being talked about more openly, even if it remains misunderstood.

    “In terms of the rise in family estrangement, we can’t really quantify the data because there’s not really a lot of statistics right now in Canada,” Hirvilammi told BayToday. “We do know it exists.”

    She says the organization is seeing increased conversation around estrangement, often referred to as “no contact,” particularly through social media and broader mental health discussions.

    “Wording can have a lot of impact on how people feel safe in terms of talking about things,” she said, adding that estrangement does not always mean completely cutting someone out of one’s life.

    “There are varying degrees that people are creating boundaries around protecting their mental health,” she said. “It doesn’t necessarily need to be full no contact.”

    Hirvilammi says the holidays can intensify pressure and stigma for people who are estranged.

    “It’s a heavily perceived time of family engagement, fond memories—it might not be fond for everybody,” Hirvilammi said.

    “The idea that we need to have a perfect holiday, that our family needs to look a specific way, those pressures can be increasingly heavy on someone who’s going through an estranged relationship.”

    CMHA psychotherapist Emily Colby says estrangement often develops over time rather than through a single event.

    “It can be things like breakdown of the family, people not respecting boundaries,” Colby explained. “What happens over time is people feel like they’re not respected or like they’re not valued in their family system.”

    She added that the emotional toll often peaks during the holidays.

    “You walk by stores, and they say, ‘Hey, get this gift for your loved ones,’” Colby said. “It creates this grief and this guilt, even the comparison among families that their family doesn’t look like the other families that they regularly see.”

    Colby says estrangement can be especially common among people in recovery.

    “People will turn to things like substance use to help them get through challenges with their family,” she said.

    When people enter recovery, she says, unresolved family issues often resurface.

    “So, a lot of times people do have an increase in stepping away or putting boundaries in place,” Colby said.

    Both Hirvilammi and Colby stressed the importance of connection, even when family relationships are strained or absent.

    “Having a sense of connection, a sense of family, is really important for your overall mental health,” Hirvilammi said. “What that looks like may not necessarily be a blood relative.”

    CMHA North Bay and District offers peer support programs that focus on connection and shared lived experience.

    “Connecting with people who have that understanding, lived experience, and additional emotional safety is really important,” Hirvilammi said.

    They hope the conversation will reduce stigma and remind people they are not alone.

    “It’s becoming very prevalent,” Colby said.

    “It’s important for these people to feel like they have somewhere to go and that they are supported, because that could be any of us.”

  • AI is coming for young people’s office jobs. That’s good news for the construction industry | Gene Marks

    AI is coming for young people’s office jobs. That’s good news for the construction industry | Gene Marks

    While standing on the sideline watching a high school soccer game, my friend, who owned a small and successful construction company, complained that his son – a senior – was starting at a respected local university that fall, which would cost roughly $200,000 over the next four years.

    “I could take the same money and set him up in a contracting business,” he said. “It would be a much better investment.”

    That was in 2010. The kid did go to that college and graduated four years later with a degree in history. Where do you think he is now? Working in the construction business.

    Ask anyone in the construction business and they’ll complain about the lack of skilled workers in their trade. The numbers support these concerns. The Associated General Contractors of America reported this past year that 92% of firms have had a hard time filling positions and 45% delayed at least one project due to labor shortages. A worker shortage model from the Associated Builders and Contractors estimates that the industry must attract 499,000 workers in 2026 to meet demand. The National Association of Homebuilders estimates the number to be as high as 723,000 annually.

    Why the shortage? Among the reasons is that younger workers have gravitated away from working with their hands over the past few decades in lieu of office jobs. Older workers are getting older – the National Center for Construction Education and Research estimates that about 41% of the current construction workforce will retire by 2031. And the current administration’s immigration policy has not only dried up the flow of potential overseas workers but have driven many construction workers – even those with proper documentation – underground.

    The building of datacenters has surged over the past few years and construction workers on those projects are in such high in demand they’re seeing pay jumps of 25% to 30% compared to their previous jobs – and in some cases, much more. Good for them, but that’s not going to last forever.

    What will happen very soon is – as interest rates continue to fall and new tax incentives begin to take hold – a new demand from both homebuyers and businesses looking to build and buy properties will – after more than five years – return and return strong. This is a cyclical industry. Things have been in the trough. But when the recovery happens, the peak will be high. Which means there will be an enormous need for new constructions workers.

    For many in the industry facing such labor shortages, that scenario is daunting. I think the opposite.

    Thanks to AI, there will be an obliteration of entry-level jobs and the meaningless white-collar work. Where will they go? There will be other opportunities – startups and new jobs we’ve never heard of (20% of today’s jobs didn’t even exist in 2000). But many will gravitate towards the trades – a place where AI can’t replace them.

    We’re already seeing this trend develop. Trade school enrollment is up significantly since the pandemic and is expected to increase as much as 7% annually through 2030, a rate significantly higher than other forms of higher education. The ranks of students studying construction trades alone rose 23% over the past year, according to another report. Young people are not stupid. They’re following the money.

  • Nvidia insists it isn’t Enron, but its AI deals are testing investor faith | Nvidia

    Nvidia insists it isn’t Enron, but its AI deals are testing investor faith | Nvidia

    Nvidia is, in crucial ways, nothing like Enron – the Houston energy giant that imploded through multibillion-dollar accounting fraud in 2001. Nor is it similar to companies such as Lucent or Worldcom that folded during the dotcom bubble.

    But the fact that it needs to reiterate this to its investors is less than ideal.

    Now worth more than $4tn (£3tn), Nvidia makes the specialised technology that powers the world’s AI surge: silicon chips and software packages that train and host systems such as ChatGPT. Its products fill datacentres from Norway to New Jersey.

    This year has been an exceptional one for the company: it has struck at least $125bn in deals, ranging from a $5bn investment into Intel – to facilitate its access to the PC market – to $100bn invested in OpenAI, the startup behind ChatGPT.

    But even as those deals have fuelled surging stock prices and paved the way for chief executive Jensen Huang’s energetic world tour, doubts have emerged about how Nvidia does business, especially as it has become increasingly central to the health of the global economy.

    The start of these concerns has been the circular nature of many of its deals. These arrangements resemble vendor financing: Nvidia lending money to customers so they can buy its products.

    The largest of these is its deal with OpenAI, which involves Nvidia investing $10bn into the company each year for the next 10 years – most of which will go to buying Nvidia’s chips. Another is its arrangement with CoreWeave, a company that provides on-demand computing capacity to big AI firms, essentially leasing out Nvidia’s chips.

    The circularity of these deals has drawn comparisons with Lucent Technologies, a telecoms company that also aggressively lent money to its customers, only to overextend itself and unravel in the early 2000s. Nvidia has aggressively rebutted suggestions of any similarity, saying in a leaked recent memo that it “does not rely on vendor financing arrangements to grow revenue”.

    James Anderson, a renowned tech investor, describes himself as a “huge admirer” of Nvidia, but said this year that the OpenAI deal presented “more reason to be concerned there than before”.

    He added: “I have to say the words ‘vendor financing’ do not carry nice reflections to somebody of my age. It’s not quite like what many of the telecom suppliers were up to in 1999-2000, but it has certain rhymes to it. I don’t think it makes me feel entirely comfortable from that point of view.”

    Other high-profile recent deals include the tech firm Oracle spending $300bn on datacentres for OpenAI in the US – with the ChatGPT developer then paying back roughly the same amount to use those datacentres. In October, OpenAI and the chipmaker AMD signed a multibillion-dollar chip deal that also gave OpenAI the option to buy a stake in the Nvidia rival.

    There is also a deal with CoreWeave where, along with a commitment to buying $22bn of data centre capacity from the cloud provider, OpenAI is receiving $350m in CoreWeave stock. Asked this month about circularity in the AI industry, the chief executive of CoreWeave, Michael Intrator, said: “Companies are trying to address a violent change in supply and demand. You do that by working together.”

    All these moves form part of OpenAI’s $1.4tn bet on computing capacity to build and operate models that, it argues, will transform economies – and make back that expenditure. OpenAI argues that, while the Nvidia and AMD deals have an investment component, it only kicks in once the chips have been bought and deployed, while the investments themselves create aligned incentives to build out AI infrastructure at huge scale.

    Graphic showing the companies Nvidia has deals with and the types of deals they are

    Nvidia has also used structures called special-purpose vehicles (SPVs) in financing deals. The best-known example is the SPV linked to Elon Musk’s xAI: an entity into which Nvidia invested $2bn, money that will be used to buy Nvidia’s chips.

    This drew comparisons with Enron, which used SPVs to keep debts and toxic assets off its balance sheets, convincing investors and creditors that it was stable while concealing ballooning liabilities.

    Nvidia has also strongly denied that it is like Enron: in the same leaked memo where it discussed Lucent, it said its reporting was “complete and transparent” and “unlike Enron” it “does not use special-purpose entities to hide debt and inflate revenue”.

    The journalist Ed Zitron, a noted sceptic of the AI boom, agrees that Nvidia is not like either company. Unlike Lucent, it does not appear to be taking on a great deal of debt to finance its circular deals, he says, and most of the customers it is supporting are not as obviously risky as Lucent’s dotcom bubble partners. And it isn’t like Enron, Zitron argues, because it’s being fairly transparent about its own complex, off-balance sheet deals.

    So what could warrant a comparison? Nvidia “is not hiding debt, but it is leaning heavily on vendor-financed demand, which creates exposure if AI growth slows,” says Charlie Dai, an analyst at the research firm Forrester. “The concern is about sustainability, not legality.”

    Essentially, whether Nvidia is able to stick the landing depends on whether AI really takes off, generating billions for its corporate users and putting companies such as OpenAI, Anthropic and CoreWeave – Nvidia’s customers – firmly in the black, and able to keep buying its systems. That possibility alone is debatable. If this does not happen, says Dai, Nvidia “could face write-downs on equity stakes and unpaid receivables”: meaning, it could lose a lot of money and its stock price could then tank.

    Approached for comment, an Nvidia spokesperson referred the Guardian to remarks its chief financial officer, Colette Kress, made to investors in early December. Kress said they were not seeing an AI bubble, instead gesturing at trillions of dollars of business that lie ahead for Nvidia in the next decade.

    In particular, Kress argued that Nvidia’s recent – massive – deals are just the start for the company, and the real money will be made in the coming years, largely through replacing almost all the chips in existing datacentres with its products.

    There is another complexity, which is that Nvidia’s health – and therefore the health of the entire global economy – also depends on whether AI takes off in time for Nvidia and its customers to service the debt from their huge datacentre buildouts and significant capital expenditures.

    Add to this a final category of concern: recent, big-ticket deals with countries such as South Korea and Saudi Arabia, worth multiple billions of dollars, whose terms are opaque. In October, Nvidia said that it would supply 260,000 of its Blackwell chips to South Korea’s government and South Korean companies. The value of this deal was not disclosed, but is estimated to be in the billions.

    Likewise with Saudi Arabia. Its government-owned AI startup, Humain, has committed to deploying up to 600,000 Nvidia chips: when that deployment will involve actual purchases, and at what price, is again undisclosed. Nvidia has a number of other strategic partnerships like this – with Italy, with the French AI champion Mistral and with Deutsche Telekom, for example – all involving thousands of chips and unknown sums.

    Governments are likely to pay. There’s nothing circular about a sovereign partnership with Germany. But the deals mean more – quite large – uncertainties nested within a straining web of commitments that require massive capital outlay, and rely on ambitious assumptions about the economy undergoing a revolution in the next years.

    “They concentrate risk in a few big customers,” says Dai. “If execution delays occur, Nvidia’s revenue recognition and cashflow could be affected.”

  • Some cannabis works about as well as ibuprofen against chronic pain, OHSU-led review finds

    Some cannabis works about as well as ibuprofen against chronic pain, OHSU-led review finds

    A systematic review of studies evaluating cannabis as a pain treatment concluded that some cannabis products do likely work to reduce chronic pain a little bit.

    The overall reduction in pain was small — lowering pain by about 1 point on a scale from 1 to 10. Yet most conventional painkillers, including ibuprofen and opioids, perform similarly in randomized controlled trials.

    But the review is likely to disappoint proponents of medical cannabis on one finding: It found that the pain reduction effect only occurred with products containing a significant amount of tetrahydrocannabinol, or THC.

    THC, one of the two main compounds in cannabis, is responsible for the psychoactive effects of the plant. The other main component is cannabidiol, or CBD.

    Oregon was the first state in the nation to decriminalize cannabis, and one of the first to legalize it for medical use and then for recreational use.

    The review, which was led by OHSU researchers and published in the Annals of Internal Medicine, analyzed the results of 25 randomized controlled trials of cannabis as a pain treatment in Europe, the United States and Canada. It was funded by the U.S. Department of Health and Human Services, as a follow-up to an earlier synthesis of the evidence on cannabis and pain.

    In recent years, pain patients and some researchers have pinned their hopes on CBD as a potential treatment that could reduce pain without inducing an unwanted “high” or other psychoactive effects. It’s also been appealing because there’s no concern that cannabidiol is addictive.

    CBD products like gummies, tinctures and salves have proliferated, and some have been marketed for pain relief.

    Roger Chou, a professor and pain management specialist at OHSU and the leading author of the review, said products containing CBD only had a trivial effect on pain in randomized controlled trials.

    “The idea or hope has been that the CBD component might be the one that provides the therapeutic effects,” Chou said. “Unfortunately, what we found was that the CBD products essentially had no impact on pain.”

    The review found that products with equal amounts of THC and CBD, or higher THC, while somewhat effective at reducing pain, were more likely to have side effects like nausea, sedation, and dizziness.

    Chou said drugs for chronic pain have a history of falling short.

    Controlled studies, he said, have found that most work about as well as non-pharmaceutical interventions like exercise, massage, and spinal manipulation.

    “We keep kind of finding that these treatments don’t work as good as we thought they would. But that’s part of what’s driven this search for other things that may work better,” he said.

    Chou said the review’s results shouldn’t necessarily dissuade anyone currently using CBD who is experiencing some benefit from it for their pain, noting that the studies measure an average response and individual experiences might be different.

    “I don’t think our study says anything that would say you have to stop your CBD,” he said.

    Additionally, the review only considered pain reduction and didn’t evaluate the evidence behind some of CBD’s other uses, like for some types of epilepsy and anxiety.drugsChou, an internal medicine doctor, said pain specialists are eager to identify safer alternatives to opioids. Patients, too, are very interested in cannabis for medical and recreational use, and have legal access to it in many states, making it important for doctors to carefully evaluate the costs and benefits.

    But, Chou said, it’s a challenging research question. Most of the products that have gone through randomized trials are medical-grade or lab-made, unlike most of the plant-based products for sale in states like Oregon that have legalized cannabis.

    Earlier this month, President Donald Trump ordered cannabis be moved to a lower schedule of drugs, paving the way for easier access and research into the plant.

    One product that the study concluded has some evidence of working, an oral spray combination THC-CBD product called nabiximols, is approved for medical use in the United Kingdom and Canada but not the United States.

    And while the review focused on cannabis’s two main components, THC and CBD, the plant contains a number of other compounds, Chou said.

    At present, the American College of Physicians recommends against cannabis as a chronic pain treatment for young adults and adolescents, patients with a history of substance use disorder, patients with serious mental illness, frail patients and those at risk of falling. Other adults should discuss the potential costs and benefits with their doctor.

  • Advancing Treatment Options for Pediatric Myasthenia Gravis: A Q&A With Jonathan Strober, MD

    Advancing Treatment Options for Pediatric Myasthenia Gravis: A Q&A With Jonathan Strober, MD

    In November during the 2025 American Association of Neuromuscular & Electrodiagnostic Medicine meeting, Jonathan Strober, MD, a pediatric neurologist from the University of California, San Francisco, and Benioff Children’s Hospital, presented new data from the ongoing phase 2/3 VIBRANCE-MG trial (NCT05265273). This trial is evaluating pediatric response to nipocalimab for generalized myasthenia gravis (MG) in patients 2 years to younger than 18 years (international arm) and in patients 8 years to younger than 18 years (US arm). At present, nipocalimab is approved for use in patients 12 years or older who are anti–acetylcholine receptor positive or anti–muscle-specific kinase antibody positive.

    In this interview, Strober emphasizes the positive safety and efficacy results seen in pediatric patients that are comparable with those seen in adult patients. He also speaks of the difficulties in diagnosing MG in a pediatric population, as well as the need to improve testing, standardize care, and overcome regulatory and insurance barriers to grant necessary treatment access to younger patients.

    This transcript was lightly edited for clarity and conciseness.

    AJMC: How was the VIBRANCE-MG trial designed to evaluate nipocalimab?

    Strober: The VIBRANCE-MG trial is the child and adolescent arm of the study that was done in the adult population on a drug called nipocalimab. Nipocalimab is an antibody that basically prevents the antibodies that you have, the immunoglobulins, from being able to be recycled. It basically drops the amount of immunoglobulins you have in your body. It doesn’t drop [the level] completely—so you still have the ability to fight infections, which is how we use the antibodies—but the antibodies are what cause a lot of the problems in myasthenia by attaching themselves to the receptors on the muscle, blocking them from being stimulated or causing them to be broken down. By dropping the antibodies you have in your blood, you can help prevent a lot of the problems that these antibodies cause and therefore improve the symptoms.

    AJMC: According to the data you presented at AANEM, what is the overall message regarding nipocalimab’s safety and efficacy?

    Strober: The trial that we presented data on looked at kids who were 12 years to just under 18 years. There is an ongoing trial for younger kids, 8 to 12 years in this country and 2 to 12 years internationally, so that we get a better sense of: does this work the same way as it does in adults and is it as beneficial as it was in adults? We’re happy to say that, yes, it kind of dropped the antibodies pretty much the same as it did for the adults, and the safety was actually really good. There was a very low risk of problems. Maybe a little bit of infection in the nose and pharynx being the most common, and COVID-19 was actually the other highest amount of adverse effects. But it’s hard. I don’t really consider that an adverse effect since people get COVID all the time. But we do know that because your antibodies are lower, you definitely are at higher risk of infection. Still, it doesn’t really seem to be that significant of a risk, which is great. Patients did really well with it.

    Most of the patients continued on through 72 weeks of taking this medication, so past the initial phase of the safety study. A lot of them were able to move from an every-other-week treatment to a once-a-month treatment. Only 1 patient had the flu during it and stopped for a little bit but then was able to go back on. Another patient had some worsening of symptoms, kind of outside the window, which happens in myasthenia—it is an up-and-down type of thing—but the patient was able to get treated for that bit of worsening and stayed on medication. Only 1 person stopped because they felt it wasn’t doing anything for them.

    AJMC: What are the next steps in your investigation of nipocalimab?

    Strober: We still have the trial ongoing, so we’re still following patients out longer. Only 3 patients had made it to the 72 weeks at the time of the cutoff when we looked at the data, so it takes a little while to kind of process the data and then be able to present it, since it all has to be scrutinized and checked out to make sure it’s all good for us to present. It is ongoing in the world; it’s international, and like I said earlier, we’re trying to get younger and younger kids into the trial.

    It’s just really hard for us to get patients into trials like these because [we have less chance of finding the antibodies in] the kids that we want to have in order to enroll them in the study, and a lot of them are not as severe as the adults. They only get problems with the eyes, or they just have mild weakness, and then some of them are really severe and then we can’t have them in a clinical trial—so it’s kind of a middle ground that we’re looking for in patients who have positive antibodies. We are still trying to recruit patients into the study. The first cohort was the 12-to-18 years range, and now the second cohort is a 2-to-12-year-old range.

    In the US, it’s only limited to 8 to 12 years, but internationally, it’s down to 2. That is the ongoing nipocalimab trial. It’s kind of an extension of this, it’s just the second cohort. We wanted to make sure it was safe in a slightly older population and ones that we have a better ability to test. Once you get down to the younger kids, it’s harder to do some of the functional testing that we do for these patients and really know if it’s helping, but we are enrolling patients in that cohort.

    AJMC: With myasthenia gravis being so rare in pediatric patients, what factors are thought to trigger the disease in younger patients?

    Strober: One is that a lot of kids, for some reason, don’t make the antibodies like we see in adults. It’s, again, something we know is working on the antibody level, so we want to make sure the patients who are in the trials have the antibodies that we can watch and make sure they’re dropping to make sure it’s effective for that. We do know that in some patients who have myasthenia, who we believe have myasthenia but are antibody negative, what we call seronegative, if we repeat their testing over time, eventually they do develop the antibodies. For whatever reason, the antibody levels get delayed in appearing in the blood.

    We’re also developing better tests to be able to pick up small amounts of antibodies better. We’re using better state-of-the-art testing to be able to confirm. We have other ways of confirming myasthenia in patients who are seronegative by doing electrical testing and testing with different medications to see if it’s something that we believe they truly have, even if they don’t have the antibodies. But again, for these studies, we need to make sure we’re really doing this study in a patient population that’s as similar as possible, and so having those antibodies helps us make sure that we’re trying to treat the same condition.

    AJMC: How do insurance and regulatory decisions influence whether patients can actually receive the most appropriate treatment?

    Strober: I don’t know exactly what they go through in Europe vs what we go through in this country. I can tell you that if it’s not approved by the FDA, it’s really hard to get insurance companies to cover it. Often they say it’s experimental if it’s not approved by the FDA, but even once it’s approved by the FDA, because the newer drugs tend to be a little bit more expensive than older drugs, and the older drugs [are] more generic [and] cheaper, a lot of insurance companies try to push us to use the older stuff, even though those still haven’t been approved for this specific condition. It’s just that they’re older and we’ve been using them for longer. It’s really important for these regulatory agencies to approve them or provide positive feedback so that these drugs can be used and [we] know they’re being used safely, but also that they can get paid for our patients.

    AJMC: What are some key unmet needs in the myasthenia gravis treatment landscape?

    Strober: I think one is, in pediatrics, again, trying to come up with better tests would be really nice. I think what we’re trying to do in our pediatric myasthenia gravis consortium, which has 6 centers currently, is to develop better tools to follow these patients but also develop a standard of care. There really is no standard of care for these patients. We’re just so used to using drugs that have only been approved for adults that people just try the different ones on kids and hope that they’re safe and hope we have the right dosing, and so kind of getting a better sense of what are people doing out there and what do we actually see in real life, in real time, what is actually working for the patients, so we can put together and say, “Hey, you know what, this is what we recommend as people who take care of these patients and take care of a good number of these patients, this is really the treatment options that you should go [with] and what route you should go in, what’s the safest for the patients, what’s the most effective for the patients.” That’s really what I want to see; I really want us to get a better understanding of pediatric myasthenia gravis and how we can follow these patients and best take care of them safely.

    I think also what I’ve learned is that the reason that there are so many studies is because now it’s become a requirement that in order to get approval for adult drugs, the companies have to have a pediatric arm. That’s been a wonderful thing.

    Just to be given the opportunity to talk about pediatric myasthenia gravis, that people are actually caring about kids with this condition, has been a huge step forward for those of us in the community who take care of it. I’ve had so many patients who have been told by providers, “Oh, myasthenia doesn’t happen in kids. They can’t have myasthenia.” We’re kind of used to that in pediatrics for these rarer diseases, so the fact that word’s getting out that, yes, kids can get myasthenia gravis and that we can treat them and we can treat them effectively and safely, it’s just wonderful to have that opportunity, so I appreciate that, and thank you.

    Sudbury Delta Charities continues happy holiday tradition

    For the 29th consecutive year, Delta Bingo and Gaming Sudbury are spreading holiday cheer by helping local organizations provide Christmas turkeys and holiday meals to families across Greater Sudbury

    Delta Bingo and Gaming Sudbury is once again stepping up to continue a happy holiday tradition by giving to families in need in Sudbury.

    For the 29th consecutive year, Delta Bingo and Gaming Sudbury and its Charitable Gaming partners – Sudbury Charities Foundation and ACT/UCT Sudbury – are spreading holiday cheer by helping local organizations provide Christmas turkeys and holiday meals to families across Greater Sudbury, said a company news release.

    Since 1996, this well known community initiative, founded by Ray Loiselle, has helped thousands of families share a warm holiday meal together, said the release. To date, the program has contributed an estimated $425,000 to The Salvation Army to continue to support local families in need.

    The success is thanks to many local partnerships, said the release. The continued partnership of organizations such as Club Richelieu de Sudbury, Ten Rainbows Children’s Foundation, and the Minnow Lake Lions Club ensures the initiative reaches approximately 1,200 families each Christmas.

    Christina Nupponen, Charity Association Coordinator, said the effort is more than giving free food.

    “This event has always been about more than providing a turkey; it’s about bringing hope and

    comfort to our community,” said Nupponen.

    “Each year, I’m inspired by the generosity of our local charities and the difference this partnership makes in the lives of so many families. The continued support and compassion shown by our community truly captures the spirit of the holiday season,” she added.

    This year, the tradition grew even stronger, said the release. In addition to supporting the Christmas turkey campaign, ACT-UCT donated a total of $50,000 to local community groups such as Inner City Home, Better Beginnings Better Futures, Go-Give Project, Our Children Our Future, Camp Quality, House of Kin, and Maison McCulloch Hospice, allowing even more local families and individuals to experience the spirit of the season. said Delta.

    Funds raised through Delta Bingo and Gaming Sudbury’s Charitable Gaming partners continue to empower our charitable groups to make a difference in the lives of thousands in our community.

    Partnered donations like these make long-standing programs possible, reflecting the lasting impact of Charitable Gaming in building stronger, more connected communities, said the release.

    Delta Bingo and Gaming Sudbury is an innovator in the charitable gaming industry, offering both paper and electronic bingo as well as Vegas-style gaming machines.
