Maintaining normal blood pressure, avoiding diabetes, and not smoking between ages 46 and 70 can delay the onset of dementia by approximately 13 years, according to a study published in the journal Neurology Open Access and reported by The Guardian and Sky News. Researchers from NYU Langone Health analyzed data from more than 12,000 participants to examine how midlife vascular health impacts long-term cognitive function.
Midlife Vascular Health and Dementia-Free Survival
People with three specific midlife risk factors face nearly three times the chance of developing dementia compared to individuals with no risk factors, according to the NYU Langone Health study. Maintaining optimal vascular health during midlife was associated with up to 12.6 additional dementia-free survival years. This figure reflects both higher dementia hazard and markedly higher competing mortality as individuals live longer lives.
Participants starting at age 55 with no risk factors typically lived more than 30 additional years without developing dementia. This duration decreased incrementally: 26 years with one risk factor, 21 years with two risk factors, and 17 years with all three. Additionally, the study found demographic variations, showing that women tended to live longer without developing dementia than men, and white participants tended to live longer without dementia than Black participants.
Did you know? Researchers note that while optimal vascular health delays cognitive decline, it also increases overall lifetime dementia risk simply because individuals live longer lives.
Global Health Updates: Ebola-Free Declaration in Uganda Amid DRC Outbreak
Uganda was declared Ebola-free by the World Health Organization (WHO) on 27 August following 42 days without a new case, according to numerous outlets. However, the outbreak in the Democratic Republic of the Congo (DRC) continues to escalate, described by authorities as the fastest-spreading Ebola epidemic ever recorded.
As of 1 September, the DRC outbreak reached nearly 6,200 confirmed cases and 3,000 deaths. A recent report from the US Centers for Disease Control and Prevention characterized the increase as unprecedented, noting approximately 5,000 cases in 100 days. The Bundibugyo strain of the virus has now been identified in six provinces across the DRC. In response, the WHO published new emergency guidance on 31 August regarding potential vaccine use, while the UK government announced a £50 million support package on 1 September.
UK Salmonella Outbreak Linked to Imported Eggs
A salmonella outbreak linked to imported eggs has caused nearly 530 illnesses and two deaths in the UK, according to the UK Health Security Agency (UKHSA). First identified in late May, the investigation centers on a rise in Salmonella Enteritidis cases caused by a single strain. The initial cluster involved 305 infections and one death between 11 August 2025 and 21 August 2026, with two subsequent clusters accounting for 223 further cases and a second death.
UKHSA investigations indicate a connection to imported eggs distributed across small cafés, restaurants, and takeaway businesses. Total UK egg imports have increased by 60% since 2021, rising from 1 billion to 1.6 billion eggs annually. Professor Ian Young, chief scientific adviser for the Food Standards Agency, advised that consumers dining out are unlikely to know if eggs carry the British Lion mark or are Laid in Britain assured. Professor Young stated: “When eating out, the safest approach for vulnerable people is to ensure [their eggs are] thoroughly cooked and to avoid dishes containing raw or lightly cooked egg, such as mousses, fresh mayonnaise or hollandaise sauce.” Overall, health authorities emphasize that the risk to the general public remains low.
Pro Tip for Consumers: When purchasing eggs in the UK, look for the British Lion mark or verification under the Laid in Britain scheme to ensure domestic safety standards.
Safety Monitoring and Reports Surrounding Weight-Loss Jabs
More than 100 deaths in the UK have been linked to the use of weight-loss jabs, according to an analysis published in The Times on 5 August. The Independent subsequently attributed more than 150 deaths to the medications, while Sky News reported a figure exceeding 200 deaths. These figures were compiled through the Medicines and Healthcare Products Regulatory Agency (MHRA) Yellow Card scheme.
Patients using these medications have reported between 150,000 and 158,000 adverse reactions to the medicines watchdog. Because suspected side effects can be reported multiple times per patient through the Yellow Card scheme, the total figure does not necessarily equal the exact number of individuals affected. Furthermore, deaths recorded via the scheme do not automatically prove causation and may stem from underlying or undiagnosed conditions.
Professor Naveed Sattar, professor of cardiometabolic medicine at the University of Glasgow, urged caution regarding these reports. Professor Sattar stated: “All medicines require ongoing monitoring, and regulators rightly continue to assess emerging safety signals. Reports of deaths in people taking weight loss medicines should be interpreted with caution and should not unnecessarily alarm the many people who are benefiting from these treatments.”
