The Influence of the COVID-19 Pandemic on Current Teaching Methods, Training, and Perception Among Romanian Surgery-Oriented Students: Cross-Sectional Study

<strong>Background:</strong> The COVID-19 pandemic prompted rapid changes in medical education, accelerating the adoption of online and distance learning methods as alternatives to traditional teaching. While these approaches offered logistical advantages, students worldwide reported significant limitations, particularly in terms of motivation, clinical exposure, and hands-on skill acquisition. Despite the increased use of digital teaching during the pandemic, core educational objectives and the mission of medical training remained unchanged, emphasizing the continued importance of practical experience. <strong>Objective:</strong> This study aims to investigate the impact of the COVID-19 pandemic on current teaching methods in medical education and to explore students’ perceptions of online learning, telemedicine, artificial intelligence, and other modern educational alternatives. <strong>Methods:</strong> This observational, cross-sectional multicentric study surveyed a cohort of Romanian medical students using a self-developed 48-item online questionnaire distributed via social media. Data were collected over 6 weeks (February-March), yielding 451 responses, of which eligible participants included students in clinical years or preclinical students interested in surgical or orthopedic careers, with a heavy representation of the Medicine and Pharmacy University of Timisoara. Statistical analysis was performed using Microsoft Excel and JASP (University of Amsterdam; version 0.95.4). <strong>Results:</strong> A total of 436 responses were analyzed, with students favoring online or hybrid formats for lectures but preferring on-site teaching for practical training. Reduced patient interaction and limited skill acquisition were the main drawbacks of online practical education. Acceptance of hybrid learning correlated with more positive perceptions of teaching methods and a lower perceived desire to cheat. <strong>Conclusions:</strong> The COVID-19 pandemic brought significant changes to the way medicine is being taught in Romania, but it also brought a clearer picture for students and medical staff on how they want medical education to be done. Online cheating remains a significant challenge, but it is being tackled at the moment with different algorithms being tested.

Evaluating the Feasibility of Technology-Based Interventions in Disability and Rehabilitation: Definitions, Considerations, and Dimensions

Technology-based interventions in the field of disability and rehabilitation, which serve assistive, therapeutic, and/or service delivery functions, are considered complex due to the skills required of providers and recipients, degree of individual tailoring, and diversity of use settings. Feasibility studies are an important step in the evolution of complex interventions that can help refine the intervention, inform implementation, and prevent wasted resources. However, guidance is lacking regarding specific considerations for feasibility studies of technology-based interventions in disability and rehabilitation, which leaves researchers and developers reliant on resources from other fields that do not address important technology properties. To advance the field, context-specific definitions, considerations, and evaluation dimensions must be explicitly outlined to ensure that feasibility studies are constructively designed to meet the unique needs of these interventions. In this viewpoint article, we (1) propose a definition and framework for feasibility studies within the specific context of technology-based disability and rehabilitation interventions, (2) highlight important and unique imperatives for feasibility studies of these interventions, and (3) articulate relevant feasibility dimensions and associated evaluation criteria for these interventions. Building on previous work, we distinguish between feasibility studies, wherein we focus on iterative intervention refinement by addressing key development questions (eg, usability), and pilot studies, which are small-scale versions of a larger study that will evaluate intervention outcomes. Integrating previous typologies, we present 13 feasibility dimensions relevant to technology-based interventions and provide sample evaluation criteria, focusing on the intervention itself rather than study design considerations (eg, trial management). This information may be useful for research and development communities (academic, clinical, or industry) to inform comprehensive feasibility studies that examine unique aspects of technology-based interventions to promote real-world impact. This contribution encourages greater harmonization of terminology and evaluation methods to streamline interpretation and comparison across studies.

User Experience and Early Clinical Outcomes of a Mental Wellness Chatbot for Depression and Anxiety: Pilot Evaluation Mixed Methods Study

Background: Artificial intelligence–powered conversational agents (ie, chatbots) are increasingly popular outlets for users seeking psychological support, yet little is known about how users experience early-stage prototypes or which therapeutic processes contribute to clinical improvement. A transparent evaluation of emerging chatbot prototypes is needed to clarify if, how, and why artificial intelligence companions work and to guide their continued development. Objective: This mixed methods pilot study evaluated user experience, acceptability, and preliminary clinical signals for an early-stage mental wellness chatbot. We also examined whether baseline symptom severity moderated clinical improvement. Methods: Three sequential cohorts (n=125) completed a 2-week, incentivized chatbot exposure (approximately 60 min per week). Participants provided first-impression ratings, qualitative feedback, and pre–post assessments of depressive symptoms (PHQ-8 [Patient Health Questionnaire-8]), anxiety symptoms (GAD-7 [Generalized Anxiety Disorder-7]), psychological distress, well-being, and loneliness. Statistical models estimated symptom change and tested interactions with baseline symptom severity. Mixed methods analysis integrated quantitative outcomes with large language model–assisted qualitative content analysis of open-ended responses. Results: Participants described the chatbot as accessible, easy to use, and emotionally validating, while citing limitations in personalization and conversational depth. Qualitative responses consistently highlighted early therapeutic processes such as emotional validation, goal setting, and perceived attunement. Regression models showed significant pre–post reductions in depressive (Hedges =–0.32) and anxiety (=–0.32) symptoms, alongside modest improvements in distress and well-being. Baseline severity moderated improvement, with marginal effects indicating larger predicted reductions at higher PHQ-8 and GAD-7 baseline scores (eg, PHQ-8=15: =–0.84; GAD-7=15: =–0.62). Conclusions: This pilot provides a comprehensive view of early chatbot development and suggests promising user experiences and preliminary symptom improvements under structured pilot conditions. By integrating experiential and exploratory clinical data, the study identifies candidate process targets to inform ongoing refinement. Findings support continued development and demonstrate procedural feasibility for progression to larger, longer-term trials evaluating engagement and clinical outcomes under more naturalistic conditions.

CAR T Cell Therapy Biomanufactured by Cellares Infused Into First Two Patients

Cellares reported that the first two patients have been dosed with Cabaletta Bio’s investigational CAR T cell therapy rese-cel (resecabtagene autoleucel) manufactured on Cellares’ Cell Shuttle™ instrument. The administration of an autologous cell therapy, which met all release criteria and was manufactured on an automated manufacturing platform, represents an important step on the journey to realizing a future where scalable manufacturing of autologous products to supply thousands of patients per year can be achieved with minimal capital investment and a low cost of goods, according to a Cellares spokesperson.

While the transformative clinical benefits of autologous CAR T cell therapy are well established in oncology, the high manufacturing costs, lack of scalability, process inconsistency, and operational inflexibility associated with the current highly manual way of manufacturing have created meaningful barriers to patient access, reducing patient accessibility to these therapies.

“This is an important milestone that reflects three years of focused collaboration between the teams at Cabaletta and Cellares,” said Steven Nichtberger, MD, co-founder, chairman, and CEO of Cabaletta Bio. “The dosing of these first two patients is an important demonstration of Cellares’ GMP manufacturing and supply chain capabilities with their automated manufacturing platform and thus represents a significant achievement toward our goal of securing high-capacity flexible supply with minimal capital investment and a low cost of goods.”

“This milestone is a transformative moment for the field of autologous cell therapy,” added Fabian Gerlinghaus, co-founder and CEO of Cellares. “For years, the promise of autologous CAR T has been constrained by manufacturing models that were never designed to scale.”

Rese-cel (formerly referred to as CABA-201) is an investigational, autologous CAR T cell therapy engineered with a fully human CD19 binder and a 4-1BB co-stimulatory domain, designed specifically for the treatment of autoimmune diseases. Administered as a single, weight-based infusion, rese-cel is intended to transiently and deeply deplete CD19-positive cells, with the goal of resetting the immune system and achieving durable clinical responses without the need for chronic therapy.

Cabaletta is evaluating rese-cel in the RESET™ (REstoring SElf-Tolerance) clinical development program, which includes multiple ongoing company-sponsored trials across a diverse and growing range of autoimmune diseases in rheumatology, neurology, and dermatology.

Development of Virtual Mental Health Stepped Care Service for a Heart Failure Remote Management Program: Qualitative Descriptive Study

Background: Depression is highly prevalent yet undertreated among people living with heart failure, indicating barriers to mental health services. Although various digital mental health interventions have been developed to detect, treat, and manage depression in this population, these interventions have seen limited integration into clinical care and a lack of implementation research. Stepped care is a service innovation that may promote the implementation of these technologies into clinical settings, but few studies have examined how these services are designed in clinical settings. Objective: This study aimed to identify strategies to address health system barriers to accessing mental health care from the perspective of people living with heart failure, clinicians, and researchers, and to incorporate these strategies into the design of a virtual mental health stepped care service within a heart failure remote management program. Methods: A qualitative description study was conducted using purposive recruitment of people living with heart failure, clinicians, and researchers from a heart failure remote patient management program. As part of a service design approach, semistructured interviews explored potential strategies to address barriers to accessing mental health services. Two researchers coded the data descriptively and constructed themes to guide the development of a virtual stepped care service. Results: A total of 22 participants were interviewed, comprising 13 people living with heart failure and 9 clinicians and researchers. Six themes were identified, comprising 4 requirements and 2 foundational principles. The requirements were to (1) adopt a collective approach to identify distress across methods, people, and time points; (2) maintain a referral-based approach; (3) rely on existing mental health human resources; and (4) offer patient choice among various mental health care options. These requirements were supported by two principles: (1) building on organizational strengths and (2) reducing treatment burden. Based on these findings, a virtual stepped care service was developed, incorporating a depression screening module, referral-based workflows, and, where clinically appropriate, patient choice in treatment selection. Conclusions: The stakeholder-informed design of this virtual stepped care service contributes to the limited literature on stepped care service design and demonstrates how such models can be tailored to their intended contexts. Although each component was designed to address health system barriers to mental health care for people living with heart failure, resource limitations may constrain the balance between feasibility and quality of care. Future research should evaluate the acceptability of this model among people living with heart failure and clinicians.

Regeneron, Telix Launch Up-to-$4.3B Cancer-Focused Radiopharma Drug, Diagnostic Collaboration

Regeneron Pharmaceuticals plans to expand its pipeline into radiopharmaceutical therapies through an up to $4.3 billion collaboration with Telix Pharmaceuticals to co-develop and co-commercialize precision oncology treatments and companion diagnostics.

The companies have agreed to partner on next-generation radiopharmaceutical therapies aimed at up to eight solid tumor targets from Regeneron’s portfolio of antibodies, generated from VelocImmune® technology, which uses the company’s own mouse platform engineered with a genetically humanized immune system.

Regeneron and Telix also said they plan to develop radio-diagnostics designed to support patient selection and treatment response assessment.

The collaboration is intended to combine the biologics expertise of Tarrytown, NY-based Regeneron, including bispecific antibody discovery, with the radiopharmaceutical development platform, global manufacturing capabilities, and supply chain infrastructure of Telix, which is headquartered in Melbourne, Australia.

“Regeneron is excited to enter the targeted radiopharmaceuticals space and explore the utility of these agents either as monotherapy or rationally combined with our immunotherapy platform, particularly in areas of high unmet patient need such as lung cancer, where our PD-1 inhibitor is a global standard of care,” Israel Lowy, MD, PhD, Regeneron’s senior vice president and clinical development unit head, oncology, said in a statement.

Lowy referred to Libtayo® (cemiplimab-rwlc), a programmed death receptor-1 blocking antibody approved for multiple oncology indications including forms of non-small cell lung cancer (NSCLC), as well as cutaneous squamous cell carcinoma, and basal cell carcinoma. Libtayo finished 2025 with $1.453 billion in worldwide net product sales, up 19% from $1.217 billion in 2024. Figures include $425 million in Q4 2025 global net product sales, up 16% from $367 million in the year-ago quarter.

‘An ideal partner’

“In our view, the deal with Regeneron validates Telix’s differentiated capabilities in radiopharmaceutical development and handling of complex supply chain logistics,” Andy T. Hsieh, PhD, a partner and biotechnology analyst with William Blair, wrote Monday in a research note. “Furthermore, given Regeneron’s track record of developing successful commercial therapeutics, we believe it is an ideal partner in bringing forth antibody-based theranostic assets.”

Telix investors appeared to somewhat agree with that analysis. The company’s ordinary shares traded on the Australian Stock Exchange climbed nearly 8% from A$14.64 ($10.34) to A$15.77 ($11.13). Telix’s American depositary shares traded on NASDAQ rose about 7%, from $10.56 to $11.24.

Hsieh reiterated William Blair’s “Outperform” rating for Telix shares based on several potential value-creating inflection points, including:

  • Continuing gains in market share gains within the prostate-specific membrane antigen (PSMA) positron emission tomography (PET) diagnostic imaging market, based on rising sales and price stability as payers have offered clarity on reimbursement—factors he said enable Telix to expand its precision medicine franchise “from a position of strength.”
  • Therapeutic franchise potential, as supported by recent positive preliminary data from part 1 of the ongoing Phase III ProstACT GLOBAL trial (NCT06520345) assessing TLX591 in metastatic androgen pathway modulation resistant prostate cancer.
  • Potential approvals of two PET imaging agents—TLX250-CDx (Zircaix®89Zr-DFO-girentuximab), designed to non-invasively detect and characterize clear cell renal cell carcinoma (ccRCC); and TLX101-Px (Pixclara®, Floretyrosine F 18 or 18F-FET), designed to image glioma. Both could “meaningfully” contribute to Telix’s profit-and-loss statement next year, the analyst predicted.

The FDA rejected both Zircaix and Pixclara last year via separate complete response letters. The agency held in April 2025 that Zircaix required additional confirmatory clinical evidence, which the company agreed to provide. On Friday, Telix said the FDA accepted its resubmitted New Drug Application (NDA) for Pixcara, assigning a target decision date of September 12 under the Prescription Drug User Fee Act (PDUFA).

In August 2025, the FDA rejected Zircaix via complete response letter, alleging deficiencies relating to its chemistry, manufacturing, and controls (CMC) package—deficiencies the company said were “readily addressable.”

“We look forward to additional updates pertaining to efficacy parameters, such as progression-free survival, an approvable endpoint, likely later this year,” Hsieh added.

Growth through acquisitions

Telix has built up its radiopharma infrastructure in recent years through acquisitions, spending $13.6 million to purchase IsoTherapeutics, a contract development and manufacturing organization (CDMO) focused on providing services to Telix and other radiopharmaceutical companies—followed by an up to $82 million buyout of radioisotope production technology firm ARTMS, which stands for alternative radioisotope technologies for medical science.

In September 2024, Telix expanded its manufacturing footprint by acquiring RLS Radiopharmacies for up to $250 million, part of an investment strategy focused around creating vertically integrated supply chain, manufacturing, and distribution.

The global radiopharmaceuticals market is predicted to grow at a compound annual growth rate of 10.1%, more than doubling from $14.2 billion this year to $31 billion in 2032, then soaring again to $54.6 billion by 2040, according to a Roots Analysis report issued in January.

Telix briefly pursued a U.S. initial public offering, which it withdrew in June 2024. The company cited market conditions as biotech IPOs met with chilly receptions on Wall Street and asserted that the offering was not predicated on the need to raise capital.

Regeneron has agreed to pay Telix $40 million in upfront cash for access to its radiopharmaceutical manufacturing platform for four initial therapeutic programs, with Regeneron holding an option to expand the collaboration to include four additional programs with additional upfront payments.

Telix and Regeneron have agreed to share equally their global commercialization costs and potential profits, with Telix retaining the option to co-promote certain potential products. However, if Telix were instead to opt out of the co-funding model for any of the original four programs, it would then be eligible to receive up to $535 million in development and commercial milestone payments, plus low double-digit royalties on future net sales, for that program.

If Telix opts out of co-funding for all four, company could achieve $2.14 billion in payments tied to achieving milestones.

For the diagnostics to be covered by the collaboration, Telix and Regeneron have agreed to jointly develop diagnostic assets, with Telix leading commercialization and Regeneron receiving a set percentage of profits.

“The collaboration with Regeneron reflects a highly complementary set of capabilities and a unique opportunity to explore what true ‘next gen’ biologics-based radiopharmaceuticals can potentially do for patients,” added Christian Behrenbruch, DPhil, managing director and group CEO at Telix. “We are well positioned to work toward the shared goal of advancing next-generation precision radiopharmaceuticals for patients with hard-to-treat cancers.”

Coverage, Traits, and Geographic Distribution of Online Surgeon Reviews: Large-Scale Cross-Sectional Analysis

Background: The use of online physician rating platforms has significantly increased and has been shown to influence physician selection. There are limited data on the use of these platforms for rating surgeons. Objective: In this study, we sought to assess the geographic distribution of and patterns in rating scores of surgeons in the United States. Additionally, we examined rating volumes across different surgical specialties and the association between peer-nominated and patient-initiated ratings on online rating platforms in the United States. Methods: We conducted a cross-sectional study by identifying 201,154 surgeons in the United States via the National Plan and Provider Enumeration System records and Doctors and Clinicians downloadable file. We assessed surgeon coverage on 3 online rating platforms and their geographic use patterns. We described the rating scores and volumes across different surgical specialties and assessed the relationship between rating platforms by comparing peer-nominated and patient-initiated online ratings. Results: A total of 78.86% (158,630/201,154) of the surgeons had ratings on at least 1 of the 3 patient-initiated websites across 11 specialties. Plastic surgeons, neurosurgeons, and orthopedic surgeons had the highest mean number of patient-initiated ratings. Surgeons with “Top Doctor” recognition from peers (23,171/201,154, 11.52%) were associated with an increased median patient-initiated rating (Healthgrades: 4.36, IQR 3.88-4.71 vs 4.20, IQR 3.64-4.64, <.001, and =0.09; Vitals: 4.30, IQR 4.00-4.60 vs 4.20, IQR 3.80-4.50, <.001, and =0.09; RateMDs: 4.20, IQR 3.80-4.50 vs 3.80, IQR 3.60-4.60, <.001, and =0.16). Geographic analysis indicated that 91.06% (295,816,471/324,870,510) of the US population lives in a county with a surgeon rated 10 times or more. Conclusions: Both patient-initiated and peer-nominated rating platforms have a comprehensive coverage of surgeons in the United States, but this coverage differs significantly between surgical specialties. Further work should assess how publicly available online ratings drive surgeon selection and their association with patient experience and postoperative outcomes.

GLP-1 Drug Improves Liver Health Independent of Weight Loss, Mouse Study Finds

Studying mice, researchers at Toronto’s Sinai Health have found that semaglutide—the active ingredient in popular weight loss drugs that mimic the gut hormone GLP-1—acts directly on a subset of liver cells to improve organ function, and does so independently of weight loss. The finding challenges long-held assumptions about how GLP-1 medicines work in the liver and could reshape how physicians treat metabolic liver disease.

Headed by Daniel Drucker, MD, a senior investigator at the Lunenfeld-Tanenbaum Research Institute, the team reported on their findings in Cell Metabolism, in a paper titled “The weight-loss-independent hepatoprotective benefits of semaglutide are orchestrated by intrahepatic sinusoidal endothelial GLP-1 receptors.”

For years, the liver benefits of semaglutide have puzzled scientists. “Glucagon-like peptide-1 (GLP-1) medicines improve metabolic liver disease through weight-loss-dependent and -independent actions,” the authors wrote. The drug was known to lower blood sugar and promote weight loss, but patients’ livers were improving in ways that those effects alone could not explain. And as the authors further noted, “The therapeutic scope of GLP-1 medicines extends beyond glycemic control and weight loss, with benefits evident in people with atherosclerotic heart disease, heart failure with preserved ejection fraction (HFpEF), peripheral artery disease, diabetic kidney disease, knee osteoarthritis, and obstructive sleep apnea (OSA).” However, as the team further pointed out, “… the mechanisms by which GLP-1 medicines improve organ dysfunction remain incompletely understood.”

Drucker has been at the forefront of GLP-1 research since the 1980s when his pioneering discoveries helped lay the groundwork for the development of GLP-1 medicines. After transforming treatment of type 2 diabetes and obesity, semaglutide and other GLP-1 medicines have been approved for other conditions including MASH (metabolic dysfunction-associated steatohepatitis). MASH is a severe form of fatty liver disease in which fat build-up, inflammation, and tissue scarring can lead to cirrhosis and liver failure. It affects about 25% Canadian adults and because it is closely linked with obesity and type 2 diabetes, treatment typically includes lifestyle interventions to reduce weight. “The approval of semaglutide for MASH highlights the importance of understanding the hepatoprotective mechanisms of GLP-1 action,” the investigators stated.

Drucker and colleagues have now found that semaglutide acts directly on the liver to reduce inflammation and scarring and improve organ function in a way that is independent of weight loss. Their finding overturns a prevailing assumption in the field that liver cells do not carry the receptor that semaglutide binds to, meaning the drug had no direct route to the organ.

Postdoctoral researcher Maria Gonzalez-Rellan, PhD, spearheaded the work that combined sophisticated mouse models of MASH with deep molecular analyses of liver cells. Her work identified two cell types carrying semaglutide receptors: liver sinusoidal endothelial cells (LSECs) and immune T cells. Although LSECs account for only about 3% of liver cell volume, they proved to be the key driver of semaglutide’s liver benefits.

A pioneer in GLP-1 biology Dr. Daniel Drucker has dedicated his career to understanding how the GLP-1 hormone, and the therapies derived from it, function in the body. His early discovery that GLP-1 stimulates insulin secretion in a glucose-dependent manner paved the way for today's widely popular medications for type 2 diabetes and obesity. Dr. Drucker's ongoing research continues to shine light on the less understood aspects of GLP-1 biology including its effects on the liver and in regulating inflammation. [Colin Dewar, Sinai Health]

LSECs line the tiniest blood vessels in the liver and are studded with pores that allow them to act as a molecular sieve, filtering substances passing between the liver and the bloodstream. Gonzalez-Rellan showed that semaglutide reversed MASH in mice that lacked the brain receptors controlling appetite, demonstrating that weight loss is not required for liver benefits. “Unexpectedly. semaglutide improves hepatic inflammation, fibrosis, and immune remodeling through actions on Glp1r+ pericentral liver sinusoidal ECs (LSECs) independent of changes in body weight (BW),” the team reported. “… we leveraged a unique model of GLP-1R deficiency, Glp1rWnt1-/- mice, which are resistant to GLP-1RA-induced weight loss. Remarkably, semaglutide markedly improved hepatic steatosis, fibrosis, and immune remodeling in the absence of weight reduction.”

In a further test, mice lacking LSEC receptors showed no liver improvement on semaglutide even after losing 20% of their body weight. Detailed molecular analyses of liver cell types showed that semaglutide shifts gene activity in LSCEs, prompting them to release anti-inflammatory molecules that act on the broader liver environment, pushing it toward a state more closely resembling a healthy, disease-free liver. “Together, the data using mouse models of MASH reveal an EC-specific, weight-loss-independent, semaglutide-regulated, GLP-1R-dependent intrahepatic network for improving liver health,” the scientists said.

“It turns out that the receptor responsible for these benefits is in a very specialized population of liver cells,” commented Drucker, who is also a professor of medicine at the University of Toronto. “And this receptor orchestrates the production of molecules that talk to many different types of liver cells to calm down the inflammatory environment that is the problem in metabolic disease.”

The findings carry practical implications. GLP-1 medicines have become widely prescribed, yet their mechanism of action in the body, beyond appetite suppression and blood sugar control, have remained incompletely understood. Knowing that semaglutide improves liver health independently of weight loss could influence prescribing decisions. “We’ve seen in clinical trials that patients who lose very little weight see the same reductions in liver inflammation, scarring and enzyme levels as those who lose a great deal of weight. Now we know why,” Drucker pointed out. In their paper the team concluded “Hence, semaglutide produces a broad proteomic remodeling of the liver, enabling restoration of metabolic homeostasis and suppression of fibrogenic and inflammatory programs. The strong concordance between single-cell transcriptional changes, bulk tissue proteomics, and biomarker signatures underscores the breadth of GLP-1R-mediated hepatic reprogramming.”

Physicians may choose lower doses that avoid the side effects associated with the higher doses needed for significant weight loss, potentially also lowering costs for patients, Drucker suggested adding “We’re not saying weight loss isn’t important because many things improve when patients lose weight. But we now know that weight shouldn’t be the only measure of success, because GLP-1 medicines will improve liver health whether or not the patient loses weight.”
