Early smoking cessation associated with higher survival rates following a lung cancer diagnosis

Quitting smoking early was associated with higher survival rates following a lung cancer diagnosis, according to a new study led by researchers at Harvard T.H. Chan School of Public Health. Compared to those who never smoked and were being treated for non-small cell lung cancer (NSCLC), current smokers had 68% higher mortality and former smokers had 26% higher mortality. Our participants’ smoking histories varied, with some having stopped smoking a few years before their diagnosis and others having stopped several decades before. This wide range gave us confidence in our results—that the benefit of pre-diagnosis smoking cessation persists even after lung cancer is diagnosed.” David Christiani, Senior Author, Elkan Blout Professor of Environmental Genetics The study was published online in JAMA Network Open on May 5, 2023. While most similar research has compared mortality among current smokers and never smokers, the majority of the study’s participants were former smokers, ...

Eli Lilly’s Alzheimer’s drug shown to significantly slow disease progression in phase 3 trial

Eli Lilly’s experimental Alzheimer’s drug, donanemab, has been shown to significantly slow cognitive and functional decline in patients with early-stage disease. The phase 3 TRAILBLAZER-ALZ 2 study met its primary endpoint, with the drug slowing the progression of the disease by 35% compared to placebo in 1,182 patients with early symptomatic Alzheimer’s disease and intermediate levels of tau protein. All secondary endpoints of cognitive and functional decline were also met and showed highly statistically significant clinical benefits, the company said. Results from the trial demonstrated that 47% of patients who received donanemab showed no disease progression a year after starting treatment, compared with 29% on placebo. Additionally, 52% of patients completed their course of treatment by one year, and 72% completed by 18 months as a result of achieving amyloid plaque clearance. Patients receiving donanemab also experienced a 39% lower risk of progressing to the next stage of disease, and ...

Researchers discover a potential cause of Parkinson’s disease

There are currently 8 million patients with Parkinson’s disease in the world. In 2021, Professor Per Saris’s group published results demonstrating that bacteria of the Desulfovibrio bacterial genus correlate with Parkinson’s disease, and that their higher number also correlates with the severity of the symptoms of the disease. Replicating the same study, Chinese researchers came to the same conclusion. “Our findings are significant, as the cause of Parkinson’s disease has gone unknown despite attempts to identify it throughout the last two centuries. The findings indicate that specific strains of Desulfovibrio bacteria are likely to cause Parkinson’s disease. The disease is primarily caused by environmental factors, that is, environmental exposure to the Desulfovibrio bacterial strains that cause Parkinson’s disease. Only a small share, or roughly 10%, of Parkinson’s disease is caused by individual genes,” says Professor Per Saris from the University of Helsinki. The goal of Professor Saris’s research group ...

US drug regulator approves world’s first RSV vaccine

By Max Matza BBC News The US Food and Drug Administration has approved a vaccine against respiratory syncytial virus (RSV) – an illness that kills thousands of Americans each year. The vaccine still needs approval from the US Centers for Disease Control and Prevention before it can be rolled out to the public. Officials say the vaccine, named Arexvy by the manufacturer GSK, is a major breakthrough that will save many lives. It could be available to people over 60 within months, officials say. “Today’s approval of the first RSV vaccine is an important public health achievement to prevent a disease which can be life-threatening,” said Dr Peter Marks, who leads the Center for Biologics Evaluation and Research at the Food and Drug Administration (FDA). RSV is a respiratory illness that typically results in cold-like symptoms for adults, but can be dangerous for young children, the elderly, and those with ...

Formus Labs’ Hip Surgery Planning Software Expands with FDA Clearance

In order to carry out a seamless joint replacement, surgeons must create a customized preoperative plan for each patient. However, surgeons having to perform multiple operations per day are often too busy to dedicate adequate time to this step. Formus Labs, a New Zealand-based medical technology startup, is on a mission to make the preoperative planning process much quicker. On Wednesday, the company received 510(k) clearance from the FDA for Formus Hip, its fully automated 3D software for hip replacement preoperative planning. The company announced its plans to expand into the U.S. last year. Wednesday’s FDA clearance represents a major milestone, as Formus can now begin to sell its product to surgeons and healthcare providers across the country. Founded in 2017, Formus seeks to solve the problem of patient dissatisfaction and unsustainable costs in joint replacement surgery, said CEO Ju Zhang in a recent interview. “Our approach to solving this ...

Researchers find possible link between self-perceived cognitive deficits and symptomatic long COVID

People who perceived that they had cognitive difficulties such as memory problems during COVID were more likely to have lingering physical manifestations of the disease than people who did not report cognitive issues, new UCLA research suggests. More than one in three people experiencing long COVID symptoms perceived such cognitive deficits, which have been found to be related to anxiety and depression. The findings indicate that psychological issues such as anxiety or depressive disorders may play a part in some people who are experiencing long COVID, technically known as post-COVID-19 condition, or PCC. “This perception of cognitive deficits suggests that affective issues—in this case anxiety and depression—appear to carry over into the long COVID period,” said senior author Dr. Neil Wenger, professor of medicine in the division of general internal medicine and health services research at the David Geffen School of Medicine at UCLA. “This is not to say ...

WHO declares end to Covid-19 global public health emergency

The spread of Covid-19 is no longer a global public health emergency, the World Health Organization declared Friday. “For more than a year, the pandemic has been on a downward trend with population immunity increasing from vaccination and infection, mortality decreasing, and the pressure on health systems easing,” WHO Director-General Tedros Adhanom Ghebreyesus said at a news conference in Geneva. “This trend has allowed most countries to return to life as we knew it before Covid-19,” Tedros said. “It’s therefore with great hope that I declared Covid-19 over as a global health emergency.” Nearly 7 million people have died from the virus worldwide since the WHO first declared the emergency on Jan. 30, 2020, according to the U.N. organization’s official data. Tedros said the true death toll is at least 20 million. The WHO’s decision comes as the U.S. is set to end its national public health emergency on ...

Researchers use skull-implantable ultrasound to help deliver chemotherapy to the brain

By Sean Whooley Leave a Comment [Screenshot from video provided by Nortwestern Medicine] Northwestern Medicine shared results from a first-in-human clinical trial for a skull-implantable ultrasound device that supports chemotherapy delivery. The device opened the blood-brain barrier to repeatedly permeate large, critical regions of the human brain. This enabled the delivery of chemotherapy injected intravenously. With the patient awake, a four-minute procedure opens the blood-brain barrier and patients go home after a few hours. Results from the Northwestern study demonstrated both a safe and well-tolerated treatment. Some patients even reached up to six cycles of chemotherapy treatment. The paper published on May 2 in The Lancet Oncology. More about the chemotherapy study The researchers say this marks the first study to successfully quantify the effect of ultrasound-based blood-brain barrier opening on the concentrations of chemotherapy in the human brain. Opening the blood-brain barrier led to approximately a four-to-six-fold increase in drug concentrations ...
