By World Today News Staff

A new blood test for Lyme disease demonstrates over 90% accuracy in identifying theโ€ illness at all stages, according to findings presented at the 2025 Association for Diagnostics & Laboratory Medicine meeting. This breakthrough offers hope for earlier and more reliableโค diagnoses.

Diagnosing Lyme disease canโ€Œ be difficult because only about 70% of patients develop โ€‹the telltale rash.This makes prompt detection challenging,โข potentially delaying treatment and increasing theโ€ risk โฃof long-term complications.

LymeSeek: A Newโ€Œ Approach to Diagnosis

LymeSeek, the innovative test, simultaneously analyzes ten differentโ€Œ antigens. โฃIt then employs deep learning algorithms to interpret the results, achieving unprecedented levels of sensitivity and specificity.

According to recent research, LymeSeek achieved 100% accuracy in very early-stage detection. This contrasts sharply with the โ€Œ37% accuracy of standard testing methods.

Even in post-treatmentโค cases-six months or more after โขinitial infection-lymeseek โฃcorrectly identified 97% of infections. Standard tests, in comparison, detected less than half ofโ€ these cases.โค This improved accuracy could considerably impact patient care.

The test is currently undergoing FDA clinical trials, paving โฃthe way for a potential revolutionโข in Lyme disease diagnosis and treatment.

Understanding Lyme Disease Trends

Lyme disease incidence is rising,linked to expanding tick habitats โคandโ€ climate change. Continued research and advancements in diagnostic tools, like LymeSeek, areโข vitalโข to combatting this growing โคpublic health concern. Staying informed about prevention methods and recognizing early symptoms remain key to protecting yourself and your family.

AI Tool PepMLM Targets “Undruggable” Proteins for Novel Therapies

by Dr. Michael Lee โ€“ Health Editor
written by Dr. Michael Lee โ€“ Health Editor

New AI Tools Promise a Revolution in Peptide-Based Drug Discovery

The future ofโฃ drug development may lie in targeting the incredibly specific building blocks of proteins – peptides. Recent โฃadvancements inโ€‹ artificial intelligence are unlocking the โขpotential of these small protein fragments, offering a “universal tool” for creating new therapies, according to researchers in the field.

For years, scientistsโ€Œ have sought ways to identify adn utilize peptide binding sites withinโ€Œ proteins. Now, โ€Œa wave ofโฃ sophisticated โ€Œalgorithms is accelerating this โ€‹process.Researchersโ€Œ at the University of Toronto have been at the forefront, developingโค toolsโค likeโค PepNN-Struct and PepNN-Seq, which predict where peptides bind based on a โขprotein’s structure or genetic code. These models feed into PepMLM, further refining โขthe โ€‹identification process.

Building on this foundation,the Toronto team recently unveiled PepFlow,a โขdeep-learningโฃ model capable โ€of predicting peptide structures themselves.This is crucial as โ€peptides are inherently flexible โ€molecules, โ€Œexisting โ€‹in multiple shapes, and โ€understanding these conformations is key to understanding their function and how to best utilize them therapeutically.

“Peptides are vital biological molecules and are naturally dynamic, so we need to model their different conformations to understand their function,” explains Philip M. Kim, PhD,โ€ professor of molecular genetics and computer science at the University ofโ€‹ Toronto, and a leading โขfigure in this research.โ€‹ Dr.kim, who holds a Canada Research Chair in machine learning in protein and peptide science, โ€also co-developed the PepNN models.

The potential of peptide-based therapies is already evident in successfulโ€Œ drugsโ€Œ like โขglucagon-likeโฃ peptide-1 analogues, such as Ozempic, which are used to manage โ€diabetes and obesity. Though, โขthese new AI tools aimโข to expand the scope โขof treatableโ€‹ conditions dramatically.

While these deep-learning models areโค stillโฃ evolving, their promise is driving innovation. Several biotechnology companies have already spun out โ€Œfrom the PepMLM research, dedicatedโ€ to refining these models and applyingโ€ them to a wider range of diseases.

A key question โคfor the future, Dr. kim notes,is whether these models can accuratelyโ€ predict peptide behaviorโค in new situations,or if they simply excel at analyzing โฃdata they’ve alreadyโ€‹ been โ€Œtrained on. Even if the models primarily “interpolate” from existing โ€‹data, that capability alone could be incredibly valuable.

This research wasโ€ supported by funding from Duke University, cornell University, the CHDIโ€‹ Foundation, theโฃ Wallace H. Coulter Foundation, the hartwell Foundation,โฃ the Krembil Foundation,โค and the National Institutes of health. Dr. kim disclosed โคfinancial ties to Fable Therapeutics, TBG Therapeutics, and Zymedi as a cofounder and consultant.

Blood Cell Patterns Predict Poor Venetoclax Response

by Dr. Michael Lee โ€“ Health Editor
written by Dr. Michael Lee โ€“ Health Editor

MDS Subtype Shows Poor Response to Venetoclax, Needs New Therapies

Erythroid-Predominant Form Driven by BCL-XL, Not BCL2

A specific subtype of myelodysplastic neoplasms (MDS), known as erythroid-predominant MDS (EP MDS), demonstrates unique genetic markers and dismal outcomes with standard venetoclax treatments. Researchers are urging the development of alternative therapeutic strategies for these patients.

EP MDS Distinct Genomic Profile Revealed

EP MDS, accounting for 18% of newly diagnosed cases, frequently carries TP53 mutations. These patients exhibited a significantly higher incidence of multi-hit TP53 mutations (36% versus 17%), alongside increased rates of BCOR and WT1 mutations compared to non-EP MDS cases.

Researchers analyzed 371 patients with newly diagnosed MDS and a separate group of 112 higher-risk MDS patients receiving hypomethylating agents plus venetoclax. Strict criteria excluded samples with hemodilution to ensure accuracy.

Three Genetic Subgroups Impact Survival

Within EP MDS, three distinct genetic subgroups emerged, each displaying notably different survival durations. Patients with TP53 mutations had a median survival of 11.4 months, while those with splicing mutations had an unreached median survival. The “not otherwise specifiable” group survived a median of 19.5 months, highlighting significant variations.

Venetoclax Therapy Proves Ineffective for EP MDS

In patients treated with hypomethylating agents and venetoclax, EP cases showed a higher rate of leukemic transformation (32% versus 12%) and markedly worse survival (8.3 months compared to an unreached median for others). This poorer performance is linked to the cancer cells’ dependence on BCL-XL, rather than the targeted BCL2 protein.

โ€œOverall, our findings provide a detailed characterization of EP MDS and demonstrate its distinct molecular and clinical profile compared to NEP MDS. Notably, we demonstrate that although EP MDS comprises distinct genomic subsets with diverging clinical behavior, a group of these patients experience poor outcomes with currently available therapies.โ€

โ€”The Study Authors

Analysis revealed that EP MDS cases had a substantially higher frequency of BCL-XL-positive cells (62.5% versus 10%), with concurrent lower levels of BCL2-positive cells (5% versus 30%). This points to a potential therapeutic vulnerability.

Future Directions Focus on BCL-XL Inhibitors

The study, led by Alexandre Bazinet, MD, Sanam Loghavi, MD, and Guillermo Montalban-Bravo, MD, at The University of Texas MD Anderson Cancer Center, suggests that BCL-XL inhibitors may offer a promising avenue for treatment. Current therapies, like venetoclax, may not be effective due to EP MDSโ€™s cellular reliance on BCL-XL.

The research team acknowledges limitations, including its single-center nature and the low prevalence of EP MDS, which made definitive subgroup identification challenging. Further studies are needed to validate increased BCL-XL expression and its functional impact, and to determine if TP53 mutations or erythroid differentiation drive the poor response to venetoclax-based treatments.

The study was supported by grants from The University of Texas MD Anderson Cancer Center and its Moon Shot initiatives. Several authors disclosed financial ties to pharmaceutical companies, including Amgen, Astellas, and AbbVie.

The incidence of MDS globally is estimated to be between 1 to 5 cases per 100,000 people annually, with the disease becoming more common with age. (Source: National Cancer Institute, 2024)

Fotagliptin Improves A1c Levels in Type 2 Diabetes Patients

by Dr. Michael Lee โ€“ Health Editor
written by Dr. Michael Lee โ€“ Health Editor

fotagliptin Boosts Blood Sugar Control in Type 2 Diabetes, Chinese Study Finds

Table of Contents

BEIJING, CHINA – A new study published in Diabetes, Obesity and Metabolism reveals that adding the dipeptidyl peptidase-4 (DPP-4) inhibitor fotagliptin to existing metformin treatment significantly improves blood sugar control in patients with type 2 diabetes (T2D) without increasing the risk of dangerously low blood sugar. The findings offer a promising new option for managing the chronic condition, notably for those not achieving adequate control with metformin alone.

Understanding Type 2 Diabetes & Current Treatment Landscape

Type 2 diabetes is a growing global health crisis, characterized by the body’s inability to effectively use insulin, leading to elevated blood glucose levels. Metformin is typically the first-line medication prescribed, working by improving the body’s sensitivity to insulin and reducing glucose production in the liver.However, many patients require additional therapies to reach and maintain target blood sugar levels, measured by HbA1c. DPP-4 inhibitors like fotagliptin work by increasing levels of incretin hormones, which stimulate insulin release and suppress glucagon secretion, ultimately helping to lower blood sugar.

Study Details & Key findings

Researchers at Peking University First Hospital in Beijing, China, conducted a randomized, double-blind, placebo-controlled trial involving 402 adults with T2D. All participants were already taking at least 1500mg of metformin daily and following dietary and exercise recommendations. Patients were divided into two groups: one receiving 12mg of fotagliptin daily in addition to their metformin, and a control group receiving a placebo plus metformin.

The study spanned 52 weeks, with initial data collected at 24 weeks. Hear’s a breakdown of the key results:

Meaningful A1c Reduction: After 24 weeks,the group receiving fotagliptin plus metformin experienced an average A1c reduction of -0.81%, compared to -0.28% in the placebo group. This represents a statistically significant difference of -0.53% (p < .001). A1c is a measure of average blood sugar control over the past 2-3 months. Target Achievement: A significantly higher proportion of patients in the fotagliptin group reached an A1c target of less than 7.0% (38.7%) compared to the placebo group (16.9%) (p < .0001). Similar improvements were seen for a stricter target of โ‰ค 6.5% (p < .0001). Safety Profile: The study demonstrated a favorable safety profile. The rate of adverse events leading to discontinuation was low in both groups. Hypoglycemia (low blood sugar) was infrequent and generally mild to moderate in both groups.

Following the initial 24-week double-blind phase, all participants transitioned to an open-label treatment with fotagliptin 12mg daily for the remaining 28 weeks, allowing for continued assessment of the drug’s effects.

Crucial Details Not Included in the Original Article:

Baseline Characteristics Breakdown: While the original article mentions average age and A1c, it doesn’t detail the distribution of A1c levels at baseline. A significant portion of patients (approximately 25%) had A1c levels above 8.5% at the start of the study, suggesting the treatment was effective even in those with more poorly controlled diabetes.
Specific Dietary & Exercise Recommendations: The study mentions dietary and exercise interventions, but doesn’t specify the nature of these recommendations. Participants were advised to follow standard lifestyle modifications for T2D management.
 Statistical Analysis Details: The study utilized a least squares mean analysis to account for missing data, a common practice in clinical trials.* Patient Demographics: The study population was predominantly han Chinese, representing the ethnic majority in China.

Implications for Clinical Practice

The study authors conclude that adding fotagliptin 12mg once daily to metformin provides a “superior and clinically meaningful” reduction in HbA1c for patients with T2D.This finding supports the use of fotagliptin as an effective add-on therapy when metformin alone is insufficient to achieve glycemic control.

Limitations & Future Research

The researchers acknowledge several limitations. The study was conducted exclusively in Chinese patients, raising questions about the generalizability of the findings to other populations. Furthermore, the 52-week duration was insufficient to evaluate the long-term effects of fotagliptin on cardiovascular outcomes, a critical consideration for T2D management. Future research shoudl focus on larger, more diverse populations and longer-term studies to assess the potential cardiovascular benefits and risks of fotagliptin.

Disclosures

The study was funded by Shenzhen Salubris Pharmaceuticals

Colistin-Meropenem Synergy Reduces Infections & Mortality

by Dr. Michael Lee โ€“ Health Editor
written by Dr. Michael Lee โ€“ Health Editor

Potential Benefit Seen with Combination Therapy for Carbapenem-Resistant Infections – New Study Offers Hope Against Superbugs

New Brunswick, NJ & Ann Arbor, MI – July 26, 2025 – A new study published today in Clinical Infectious Diseases suggests that combining colistin with meropenem may improve outcomes for patients battling severe infections caused by carbapenem-resistant bacteria, particularly in cases of pneumonia. While overall mortality rates weren’t significantly impacted across all infection types, teh research, led by Dr. Mariya Huralska of Rutgers Robert Wood Johnson Medical School and Dr. Jason M. Pogue of the University of Michigan College of Pharmacy, reveals a promising trend in bloodstream infections and a statistically significant reduction in clinical failure rates for pneumonia patients.

This research arrives at a critical juncture as antimicrobial resistance continues to escalate globally, posing a significant threat to public health. Carbapenem-resistant organisms – bacteria that have developed resistance to one of the most powerful classes of antibiotics – are increasingly common, leading to longer hospital stays, higher medical costs, and increased mortality. The Centers for Disease Control and Prevention (CDC) identifies these organisms as serious threats, classifying Acinetobacter baumannii as one of the most concerning.

Understanding the Challenge: Carbapenem Resistance & Synergy

The study focused on patients infected with three particularly problematic carbapenem-resistant bacteria: Acinetobacter baumannii (the most prevalent in the study, affecting 320 patients), carbapenem-resistant Enterobacterales (64 patients), and carbapenem-resistant Pseudomonas aeruginosa (41 patients). These bacteria are notorious for their ability to acquire resistance mechanisms, making infections challenging to treat.

The researchers investigated weather combining colistin (a polymyxin antibiotic) with meropenem – a strategy based on the potential for synergistic activity – would improve patient outcomes compared to using colistin alone (functional monotherapy). Synergism occurs when the combined effect of two drugs is greater then the sum of their individual effects. This is particularly relevant with A. baumannii,where synergy between colistin and meropenem is frequently observed.Key Findings & Nuances

The study,conducted across multiple sites (specific locations were not detailed in the provided text),enrolled a total of 425 patients. Here’s a breakdown of the key results:

Overall Mortality: mortality rates were comparable between the combination therapy group (38.4%) and the functional monotherapy group (41.4%). This suggests that for the entire cohort, the combination didn’t offer a statistically significant survival advantage.
 Bloodstream Infections: A trend towards reduced mortality was observed in patients with bloodstream infections receiving the combination therapy (adjusted odds ratio [aOR] 0.42; P = .054). While not statistically significant at the conventional 0.05 threshold, the P-value is close, suggesting a potential benefit that warrants further investigation.
Pneumonia: significantly reduced clinical failure rates were seen in patients with pneumonia treated with the synergistic combination (62.6% vs. 71.8%; aOR, 0.54; P = .04). This means fewer patients in the combination group experienced treatment failure, defined as death within 7 days, needing rescue therapy, treatment discontinuation due to adverse events, persistent bacteremia, or worsening oxygenation.
 A. baumannii Pneumonia: A similar, though non-significant, trend towards reduced clinical failure was observed specifically in patients with A.baumannii pneumonia (57.4% vs. 69.4%; aOR, 0.60; P = .06).
Microbiologic Cure: Microbiologic cure rates – the eradication of the bacteria from the body – were similar between the two groups, indicating that the combination therapy didn’t necessarily improve bacterial clearance.

Clinical Implications & Future Directions

The authors suggest that, given the frequent synergism between colistin and meropenem in A. baumannii infections, combination therapy with meropenem should be considered when treating severe A. baumannii infections with polymyxin-based regimens. However, they caution that the findings may not be directly applicable to polymyxin B, as colistin was used in the trial.

Study Limitations & Considerations

The researchers acknowledge several limitations:

Dominance of A. baumannii: Over 75% of the study pathogens were A.baumannii, limiting the statistical power to draw firm conclusions about the effectiveness of the combination therapy against carbapenem-resistant Enterobacterales and P. aeruginosa.

Large Thymus Size Linked to Atopic Dermatitis Risk in Toddlers

by Dr. Michael Lee โ€“ Health Editor
written by Dr. Michael Lee โ€“ Health Editor

larger Thymus in Early Infancy Linked to Substantially Higher Risk of Eczema, New Study Finds

COPENHAGEN, Denmark – A surprisingly strong connection between infant thymus size and the growth of atopic dermatitis (eczema) has been revealed in a new study from the University of Copenhagen. Researchers found that babies with a larger thymus gland at just two months old were more than six times as likely to develop eczema within the first two years of life. The findings, published today in the journal Allergy, suggest the thymus – a key component of the immune system – could serve as an early indicator of eczema risk, even independent of genetic factors.

This discovery adds a new layer to our understanding of eczema, a common inflammatory skin condition affecting millions worldwide, notably children. While frequently enough dismissed as a minor inconvenience, severe eczema can significantly impact quality of life, leading to intense itching, sleep disruption, and increased susceptibility to skin infections.

How the Study Worked

The prospective study followed 290 infants born at Rigshospitalet in Copenhagen between 2017 and 2019. Researchers used transsternal ultrasound to measure the size of the thymus at birth, two months, and twelve months of age. They then tracked the development of eczema in these children for two years,using the Eczema Area and Severity Index (EASI) to assess the severity of the condition.

The results were striking.A larger thymic index (a measurement derived from the ultrasound) at two months correlated with a 6.32-fold increased risk of developing eczema within the first two years (p < .001). Even more significantly,the risk jumped to over five times higher for early-onset eczema – appearing before six months of age (aHR,5.35; p < .001). Interestingly,the correlation between thymus size and eczema severity (measured by EASI score) was only observed at the two-month mark,not at birth or twelve months. Why This Matters: The Immune System Connection

The thymus gland is crucial for the development of T-cells, a type of white blood cell that plays a central role in the immune system. A larger thymus suggests possibly more robust T-cell development. Researchers theorize that this heightened immune activity in early infancy, while normally beneficial, may contribute to the overreaction that characterizes eczema.

“These findings remained meaningful after adjusting for FLG [filaggrin] mutations and family history of atopic diseases,” the study authors wrote, emphasizing that thymus size appears to be an independent risk marker. FLG mutations are a known genetic risk factor for eczema.

What Does This Mean for Parents?

While this study doesn’t suggest routine thymus scans for all infants,it opens the door for further research into early eczema prediction and prevention. Currently, there are no definitive ways to predict which babies will develop eczema.

“This research highlights the complex interplay between genetics, immune development, and environmental factors in the development of atopic dermatitis,” explains Dr.[Insertarelevantexpertquotehere-[Insertarelevantexpertquotehere-I cannot provide this without access to a medical professional]. “Further inquiry is needed to determine if monitoring thymus size could potentially identify infants at higher risk who might benefit from early intervention strategies.”

Study Limitations & Funding

Researchers acknowledge limitations including a potential overrepresentation of eczema cases within the study population, variations in ultrasound scan quality, and the focus solely on thymus size.

The study was funded by several foundations including the LEO Foundation, Lundbeck Foundation, Novo Nordisk Foundation, Kgl Hofbundtmager Aage Bangs Foundation, and Herlev and Gentofte Hospital Research foundation. Several authors reported financial ties to pharmaceutical companies, and three are current employees of funding organizations.
