US FDA advisers vote against Otsuka's PTSD combination treatment
The panel voted 10-1 to say the available data does not establish the efficacy of the drug, brexpiprazole, in combination with Zoloft for treating the condition.
PTSD, a disorder caused by very stressful events, affects about 4% of U.S. adults and is commonly associated with war veterans. But natural disasters, abuse or other trauma may also trigger the condition in civilians.
The recommendation comes after the FDA's staff reviewers on Wednesday raised efficacy concerns over the use of the combination therapy, citing inconsistent trial results and a modest treatment effect.

Top medical body concerned over RFK Jr's reported plans to cut preventive health panel
A top US medical body has expressed 'deep concern' to Robert F Kennedy Jr over news reports that the health secretary plans to overhaul a panel that determines which preventive health measures including cancer screenings should be covered by insurance companies. The letter from the the American Medical Association comes after the Wall Street Journal reported on Friday that Kennedy plans to overhaul the 40-year old US Preventive Services Task Force because he regards them as too 'woke', according to sources familiar with the matter. During his second term, Donald Trump has frequently raged against organizations and government departments that he considers too liberal – often without any evidence. The US president, and his cabinet members such as Kennedy, have also overseen huge cuts and job losses across the US government. The taskforce is made up of a 16-member panel appointed by health and human services secretaries to serve four-year terms. In addition to cancer screenings, the taskforce issues recommendations for a variety of other screenings including osteoporosis, intimate partner violence, HIV prevention, as well as depression in children. Writing in its letter to Kennedy on Sunday, the AMA defended the panel, saying: 'As you know, USPSTF plays a critical, non-partisan role in guiding physicians' efforts to prevent disease and improve the health of patients by helping to ensure access to evidence-based clinical preventive services.' 'As such, we urge you to retain the previously appointed members of the USPSTF and commit to the long-standing process of regular meetings to ensure their important work can be continued without disruption,' it added. Citing Kennedy's own slogan of 'Making America healthy again,' the AMA went on to say: 'USPSTF members have been selected through an open, public nomination process and are nationally recognized experts in primary care, prevention and evidence-based medicine. They serve on a volunteer basis, dedicating their time to help reduce disease and improve the health of all Americans – a mission well-aligned with the Make America Healthy Again initiative.' According to the Affordable Care Act, public and private insurance companies must cover any services recommended by the Preventive Services Task Force without cost sharing. In a statement to MedPage Today, Department of Health and Human Services spokesperson Andrew Nixon did not confirm the reports, instead saying: 'No final decision has been made on how the USPSTF can better support HHS' mandate to Make America Healthy Again.' Reports of Kennedy's alleged decision to overhaul the taskforce come after the American Conservative published an essay earlier this month that described the taskforce as advocating for 'leftwing ideological orthodoxy'. It went on to accuse the panel of being 'packed with Biden administration appointees devoted to the ideological capture of medicine', warning that the 'continued occupation of an important advisory body in HHS – one that has the capacity to force private health insurers to cover services and procedures – by leftwing activists would be a grave oversight by the Trump administration'. In response to the essay, 104 health organizations, including the American Medical Association, issued a separate letter to multiple congressional health committees in which they urged the committees to 'protect the integrity' of the taskforce. 'The loss of trustworthiness in the rigorous and nonpartisan work of the Task Force would devastate patients, hospital systems, and payers as misinformation creates barriers to accessing lifesaving and cost effective care,' the organizations said. In June, Kennedy removed all 17 members of a US Centers for Disease Control and Prevention panel of vaccine experts. Writing in a Wall Street Journal op-ed, he accused the committee of having too many conflicts of interest. Kennedy's decision to overhaul the immunization panel was met with widespread criticism from health experts, with the American Public Health Association executive director Georges Benjamin calling the ouster 'a coup'. 'It's not how democracies work. It's not good for the health of the nation,' Benjamin said.

Urgent recall of popular cheeseburgers that can trigger 'life-threatening allergic reaction'
The FDA issued an urgent warning about a midwestern burger and sandwich brand after an undeclared allergen was found in food items sold across three states. Sheehan Brothers Vending, an Ohio-based catering business, recalled six of its staple meals after health officials detected sesame that was not noted on product labels earlier this month. Cheeseburgers, Spicy Chicken Sandwiches, Italian Mini Subs, Pepperoni Pizza Subs, Chili Cheese Coneys and BBQ Riblets with Coleslaw were named in the recall. Affected sandwiches were sold by the family business between July 2 and July 8 in 'micro markets' and vending machines across Ohio, Northern Kentucky and Eastern Indiana. The ready-to-go meals are premade and only need to be reheated in the microwave for less than a minute. All the items were individually wrapped in plastic and labeled with green and white stickers on the front. The FDA classified the recall as a Class I health risk, which is the most dire type of recall. 'People who have an allergy or severe sensitivity to sesame run the risk of a serious or life-threatening allergic reaction if they consume this product,' the agency wrote. 'Individuals exhibiting signs or symptoms of foodborne illness or allergies should contact a physician immediately.' Fortunately, no illnesses have been reported in connection to the undeclared allergen. Anyone with a sesame allergy who bought the contaminated products should throw them out and contact Sheehan Brothers Vending for a replacement pack. The family-owned business specializes in meeting the catering and vending needs of of office buildings. According to the company website, its vending machines 'carry homemade and name-brand sandwiches, salads, entrees, snacks, and beverages that offer healthy alternatives for consumers.' Sheehan Brothers also installs and runs micro markets, which are self-service shops and cafes in business and public spaces. 'We continually innovate to provide the most popular snacks, beverages, and homemade food items daily,' the company, founded in 1956, wrote. About 33 million people living in the US have a food allergy, according to Food Allergy Research & Education (FARE). Sesame is the ninth most common food allergy in the United States, the American Academy of Allergy, Asthma & Immunology reported. 'When a person with an allergy to sesame is exposed to sesame, proteins in the sesame bind to specific IgE antibodies made by the person's immune system,' FARE wrote. 'This triggers the person's immune defenses, leading to reaction symptoms that can be mild or very severe.' The FDA recognizes nine major allergens: milk, eggs, sesame, fish, tree nuts, crustacean shellfish, peanuts, wheat and soybeans.

This fuzzy animal friend may be the key to treating schizophrenia
Llamas – likely without red pajamas – may hold the key to treating schizophrenia. The serious brain disorder causes people to interpret reality abnormally, and affects approximately 3.7 million U.S. adults between the ages of 18 to 65 years old, according to the nonprofit RTI International. But the domesticated South American woolly animal might be be able to help. French researchers said this week that they had used llama antibodies, or proteins that help to protect the immune system, to design a tiny fragment of an antibody known as a 'nanobody' that will trigger a neurotransmitter in the brain involved in regulating neural activity. Neurotransmitters are chemical molecules that carry messages or signals from one nerve cell to the next target cell, according to the Cleveland Clinic. No llamas were harmed in the study and researchers can identify nanobodies in a petri dish. In the past, llama antibodies have also proven effective in fighting Covid and other 'SARS-like' viruses. When scientists at the Institute of Functional Genomics injected the molecule into the veins or the muscles, it was able to break the blood-brain barrier and effectively reach brain receptors. The barrier is a a tightly locked layer of cells that defend your brain from harmful substances. Studying the impact of the nanobodies in two tests using mice, the researchers found that they corrected cognitive deficits that were observed. There was an improvement of cognitive function with just one shot, and a prolonged effect over one week. Clinical studies are now required to show that their findings could be a new avenue of treatment for schizophrenia. "In humans obviously we don't know [yet], but in mice yes, it is sufficient to treat most deficits of schizophrenia," molecular biologist Jean-Philippe Pin told Newsweek.. He was a co-author of the research which was published in the journal Nature. Pin said that medications currently given to schizophrenia patients "treat the symptoms well, but less the cognitive deficits." The cause of the chronic condition remains unknown, but the World Health Organization says it is thought that an interaction between genes and a range of environmental factors may be the reason. The exact prevalence of schizophrenia is difficult to measure. Some have tied cases in Canada to cannabis use. Although schizophrenia can occur at any age, people are typically diagnosed between the ages of 16 and 30. Symptoms vary from person to person. There is no cure, but it can be treated through antipsychotic medications, talk therapy, and self-management strategies, the National Alliance on Mental Illness says. The study's authors hope to add this strategy to the list. 'This research confirms the potential of nanobodies as a new therapeutic strategy for acting on the brain, with their use eventually being broadened to include the treatment of other neurological illnesses,' the institute said in a statement.
