AI Leverages Tumor Genetics to Predict Patient Response to Chemotherapy

Understanding tumor responses to drugs becomes challenging due to the complex nature of DNA replication, a critical target for many cancer treatments. All cells, including cancer ones, depend on a sophisticated system for DNA replication during cell division. Most chemotherapies aim to disrupt this replication process in rapidly multiplying tumor cells. Given the diverse genetic mutations in tumors, predicting drug resistance remains a formidable challenge. Now, scientists have developed a machine learning algorithm capable of predicting when cancer will resist chemotherapy. This model was specifically tested on cervical cancer, accurately predicting responses to cisplatin, a widely used chemotherapy drug. It efficiently identified tumors likely to resist treatment and shed light on the molecular mechanisms driving this resistance. Developed by the University of California San Diego School of Medicine (La Jolla, CA, USA; ), the algorithm assesses how various genetic mutations collectively impact a tumor’s response to DNA replication-inhibiting drugs. The ...

MHRA introduces new restrictions for fluoroquinolone antibiotics

From today, fluoroquinolone antibiotics given systemically (by mouth, injection, or inhalation) must only be administered when no other antibiotics are appropriate for use, the Medicines and Healthcare products Regulatory Agency (MHRA) has announced. This means that fluoroquinolones should only be prescribed when other recommended antibiotics have failed, will not work due to resistance, or are unsafe to use in an individual patient. This is a strengthening of the previous regulations which stated that fluoroquinolones should not be prescribed for mild to moderate or self-limiting infections, or non-bacterial conditions.The MHRA conducted a thorough review into the effectiveness of current measures to reduce the risk of potentially long-term adverse reactions to fluoroquinolone antibiotics and sought advice from the Commission on Human Medicines (CHM). The review process considered available evidence, including Yellow Card reports submitted by patients and healthcare professionals, and the experiences of people affected by these side effects. The restrictions have ...

For more than 2 years, Johnson & Johnson has been plotting its future as a two-sector company. In the wake of the company’s consumer healthcare spinoff last summer, the company’s fourth-quarter results offer plenty of signs of life from the new-look J&J.After wrapping up 2023 with a total haul of $85.2 billion, the company is heading into 2024 with “multiple catalysts for growth,” CEO Joaquin Duato said on J&J’s fourth-quarter and full-year earnings conference call. Across J&J’s innovative medicines portfolio, the company’s oncology and immunology medicines generated the lion’s share of sales in 2023’s fourth quarter, helping the unit achieve operational growth in the U.S. of 9.5% during the period. Worldwide, J&J’s pharma business reeled in $13.72 billion during the fourth quarter, a 4% increase from the same period in 2022.On the immunology front, J&J’s antibody blockbuster Stelara grew its market share and demonstrated continued strength in inflammatory bowel disease (IBD), J&J said in ...

Johnson & Johnson inks $700M deal to resolve talc consumer protection claims from 42 states

After failing to resolve a mountain of talcum-powder lawsuits through two unsuccessful bankruptcy attempts, Johnson & Johnson has agreed to a $700 million settlement that would free the company from some consumer protection claims—and a small part of the talc litigation that it faces. J&J plans to pay $700 million to 42 states and the District of Columbia to settle claims that the company did not warn of the potential health risks posed by its talcum-based products, including its iconic Johnson’s Baby Powder.Bloomberg first revealed the agreement two weeks ago, with the company confirming the news to the Wall Street Journal on Tuesday. “Consistent with the plan we outlined last year, the company continues to pursue several paths to achieve a comprehensive and final resolution of the talc litigation,” J&J litigation chief Erik Haas said in an emailed statement confirming the report. “We will continue to address the claims of those who do not ...

Handheld White Blood Cell Tracker to Enable Rapid Testing For Infections

White blood cells (WBC), or leukocytes, are key indicators of an individual’s immune system health. High or low WBC counts can signify the severity of an infection, indicate life-threatening conditions like sepsis, or assist in monitoring patient responses to therapies like chemotherapy and psychotropic drugs. Generally, the blood collected for WBC testing is sent to a central lab for analysis that sends results within hours, making it inconvenient and delaying time-sensitive diagnosis or treatment. Now, an innovative device can rapidly count a person’s WBC with a single drop of blood, similar to the way glucometers rapidly scan for blood sugar levels, enabling rapid testing and improved triaging for infections. Called the CytoTracker Leukometer, the device developed by researchers at Rutgers startup RizLab Health Inc. (Princeton, NJ, USA) can quickly aid the detection of elevated or reduced WBC counts. The device has undergone comprehensive testing, comparing its performance with conventional ...

New Liquid Biopsy Approach Improves Blood Tests’ Ability to Detect Circulating Tumor DNA

Tumors continuously release DNA from dying cells into the bloodstream, which is rapidly broken down. This makes it difficult for existing blood tests to detect the minute amounts of tumor DNA present at any given time. Now, a team of researchers has developed an innovative method to amplify the detection of tumor DNA in blood, a breakthrough that could enhance cancer diagnosis and treatment monitoring. Researchers at Massachusetts Institute of Technology (MIT, Cambridge, MA, USA) have created “priming agents,” injectable molecules that temporarily slow the clearance of circulating tumor DNA from the bloodstream. These priming agents target the body’s two main mechanisms for removing circulating DNA: DNases, enzymes that break down DNA in the blood, and macrophages, immune cells that absorb cell-free DNA during blood filtration through the liver. The researchers developed two types of priming agents. The first is a monoclonal antibody that attaches to circulating DNA, shielding ...
