Get Ready, Brazil. The “Good Mosquitoes” Are Coming

“Officials say that nearly all the mosquitoes in Niterói now carry Wolbachia. As a result, the World Mosquito Program, Fiocruz, and local health authorities documented a roughly 90% drop in what had been several thousand cases of dengue annually when comparing the 10 years prior to Wolbito introduction to the five years afterward.

In contrast, just across the bridge, in neighboring Rio de Janeiro where the modified mosquitoes have not yet been introduced, dengue levels have remained reasonably high during the same period.

The levels of two other mosquito-borne viruses in Niterói — chikungunya and Zika — also fell by over 96% and 99%, respectively, when comparing the roughly five years before and after Wolbito introduction. Case counts dropped from the thousands to a mere handful.”

Sudan and South Sudan Eliminate Maternal and Neonatal Tetanus

“Neonatal tetanus, a silent but preventable killer, claims the lives of newborns within their first days of life, particularly in settings with unsafe delivery practices and poor umbilical cord care. Through successful vaccination campaigns, both South Sudan and Sudan have achieved Maternal and Neonatal Tetanus Elimination (MNTE), a significant public health milestone.”

mRNA-1010 Superior to Standard-Dose Vaccine for Preventing Flu

“For adults aged 50 years or older, an investigational messenger RNA (mRNA)-based vaccine (mRNA-1010) is superior to standard-dose licensed vaccines for preventing influenza-like illness, according to a study published in the New England Journal of Medicine

Overall, 20,350 participants received mRNA-1010 and 20,353 received the standard-dose comparator. The researchers found that 2.0% and 2.8% of the recipients of mRNA-1010 and the standard-dose comparator, respectively, had RT-PCR-confirmed, protocol-defined influenza-like illness, corresponding to a relative vaccine efficacy of 26.6% and meeting the criteria for noninferiority, superiority, and higher-level superiority. Solicited adverse reactions occurred more often with mRNA-1010 than the standard-dose comparator; they were mainly mild-to-moderate and transient. Overall, 2.2% and 1.9% of recipients of mRNA-1010 and the standard-dose comparator, respectively, had serious adverse events.”

Teen, Young Adult Suicides Fall After Crisis Hotline Shifts to Three Digits

“Suicide deaths among young adults and youth declined after a federal agency simplified the phone number for a national crisis hotline and increased resources, a new study says…

Patel, a clinical fellow in surgery at Harvard Medical School and surgical resident at Brigham and Women’s Hospital, said that when researchers first examined figures for all age groups, the lifeline’s potential impact appeared to be slight.

But when they broke down the data, they saw a significant decline among those age 15 to 34 — encompassing the high-risk teenage years — that had been masked by results in other groups.

The researchers noted a decline from both observed suicide deaths in 2022 and from predictions based on a long-term upward trend. In 2010, about 11 suicides per 100,000 were reported in that age group. By 2022, that had risen to nearly 18 per 100,000. Three years after the 988 number went online, however, that had fallen to approximately 15 per 100,000, according to the study…

In addition to the nationwide figures, state-by-state data also shows an association with the establishment of the 988 number.

The 10 states with the largest increases in calls after its establishment — 146.2 percent more — also saw a larger decline in suicide deaths, about 18.2 percent. The 10 states with the lowest call volume increase — about 23.6 percent — saw a lower, 10.6 percent decline.”

AI Finds Signs of Pancreatic Cancer Before Tumors Develop

“By the time doctors detect pancreatic cancer, it’s often too late to treat effectively. But a new study suggests that artificial intelligence might be able to find signs of the disease before tumors are visible on a scan.

An AI model developed at the Mayo Clinic in Rochester, Minnesota, detected abnormalities on patients’ CT scans up to three years before they were diagnosed with pancreatic cancer, according to research published this week in the journal Gut.

The scientists behind the model, which is now being evaluated in a clinical trial, trained it by feeding it CT scans from patients who had been screened for other medical conditions then were later diagnosed with pancreatic cancer. The team then had radiologists review the scans and compared their ability to find early signs of cancer to that of the AI model. The model was found to be three times better at identifying the early signs.”
