Cardiac arrest deaths among marathoners have decreased, study finds
Though more people are participating in long-distance-running events than ever before, a recent analysis found that the incidence of cardiac arrest among those running such races remains stable — and death rates from cardiac arrests during long races have fallen.
Published in JAMA, the study reviewed the Race Associated Cardiac Event Registry (RACER), which collected information on the incidence of cardiac arrest during marathons and half-marathons, and compared race data from 2010 to 2023 with data from 2000 to 2009. The RACER database included 443 U.S. marathons and half-marathons between 2010 and 2023.

Measles vaccination rates drop after COVID-19 pandemic in counties across the US
Childhood vaccination rates against measles fell in the years after the COVID-19 pandemic in nearly 80% of the more than 2,000 U.S. counties with available data — including in states that are battling outbreaks this year. A Johns Hopkins University study, published in JAMA this week , illustrates where more vulnerable communities are located. The results mirror trends established at state and national levels : Routine childhood vaccination rates are dropping.

Fact or Fiction: Postoperative Pain Management
Effective postoperative pain management is crucial for enhancing patient recovery and reducing complications. Guidelines emphasize a multimodal approach, integrating pharmacologic and nonpharmacologic strategies to address the complex nature of postoperative pain. This includes using regional anesthesia techniques, non-opioid analgesics, and complementary therapies tailored to individual patient needs. Such comprehensive strategies aim to minimize opioid consumption and associated adverse effects, thereby promoting better outcomes. Persistent opioid use is reported in up to 10% of opioid-naive patients more than 90 days after surgery. Among those discharged with opioid prescriptions, approximately 70% retain a supply at home — and of that, 90% is stored insecurely. A recent study published in JAMA found that spinal surgery, older age, longer hospital stay, history of substance use disorder, and previous opioid discontinuation before surgery were associated with new-onset persistent opioid use after surgery. These findings underscore the importance of minimizing opioid exposure in the perioperative period. Learn more about opioid abuse. The FLACC scale is a validated tool recommended for assessing postoperative pain in children 2 months to 19 years of age. However, it may be less suitable for evaluating procedural pain. In preverbal or nonverbal children with cognitive impairments, standard FLACC assessments can be less reliable. In such cases, the revised FLACC scale, which incorporates individualized behavioral cues, may offer a more accurate assessment. Learn more about pain assessment. Combined guidelines from the World Society of Emergency Surgery, Global Alliance for Infection in Surgery, Italian Society of Anesthesia, Analgesia, and Resuscitation, and the American Association for the Surgery of Trauma recommend multimodal analgesia, rather than the use of a single class of drugs, to manage postoperative pain. This approach enhances pain relief and helps reduce opioid consumption as well as adverse effects associated with a single drug class. In the absence of contraindications, acetaminophen, gabapentinoids, and nonsteroidal anti-inflammatory drugs are recommended as components of multimodal anesthesia. A step-up strategy that incorporates major opioid drugs when necessary should be employed. The Centers for Disease Control and Prevention similarly recommends a multimodal approach in their opioid prescribing guidelines. Learn more about perioperative medication management. IV administration provides the most rapid onset of analgesia but does not offer superior pain control compared to the oral route. As such, IV analgesics should be reserved for situations where oral administration is not feasible, as in cases of gastrointestinal dysfunction. Postoperative pain management guidelines concur that the oral route is the preferred route of postoperative analgesic administration. Learn more about local and regional anesthesia. Guidelines state that the TAP block is both a safe and effective approach to managing postoperative pain. Abdominal wall blocks serve as an effective component of multimodal analgesia, contributing to opioid-sparing strategies. TAP blocks have been shown to significantly reduce pain scores at 12 hours postoperatively. For laparoscopic abdominal procedures, a rectus sheath block may be considered an appropriate alternative to a TAP block within a multimodal analgesia plan. Learn more about the TAP block.

Measles vaccination rates drop after COVID-19 pandemic in counties across the US
Childhood vaccination rates against measles fell in the years after the COVID-19 pandemic in nearly 80% of the more than 2,000 U.S. counties with available data — including in states that are battling outbreaks this year. A Johns Hopkins University study, published in JAMA this week, illustrates where more vulnerable communities are located. The results mirror trends established at state and national levels: Routine childhood vaccination rates are dropping. 'When you look at the state level or national level … you really don't see those drastic drops. Those are there. They're real and they're really problematic,' said Lauren Gardner, an expert in infectious disease modeling at Johns Hopkins University who is the paper's senior author. Gardner also built the university's COVID-19 database. Most of the measles cases in the U.S. this year — 1,088 nationally as of Friday — are in unvaccinated people. It has been spreading among communities due to international and domestic travel. Three people have died from measles during this year's outbreaks, and 2025 is inching closer to becoming the worst for measles in more than three decades. Measles was eliminated in the U.S. in 2000, and the vaccine is safe and highly effective. Public schools nationwide require two doses of the measles, mumps and rubella vaccine before kindergarten, but the number of children with non-medical exemptions from those requirements hit an all-time high in the 2023-2024 school year. Health experts say community-level vaccination needs to be at 95% or higher to prevent outbreaks. The Johns Hopkins study looked at 2,066 counties across 33 states, comparing kindergarten vaccination rates averaged over school years from 2017-2020 to averages from 2022-2024. Where kindergarten data wasn't available, the researchers used a comparable rate. Here's what it looks like in counties where there have been outbreaks this year, including in Texas counties that are the epicenter of measles. Texas has logged 742 measles cases since late January, most in West Texas. Gaines County has 411 cases, the most in the state. Almost 2% of its population got measles. While the county saw a two percentage-point increase in vaccination rates after the pandemic, its 82.4% rate remains below herd immunity. Terry County (60 cases) and Yoakum County (20 cases) dropped below the 95% threshold for herd immunity after the pandemic, to 93.7% and 91.8% respectively. Lubbock County — which has seen 53 cases and is the closest metro area to Gaines County — was just below 95% before the pandemic, but dropped three percentage points after to 91.8%. El Paso County on the border of Mexico has had the third-most measles cases in Texas this year with 57. Its vaccination rate is higher than 95% but saw a 2.1 percentage-point decline to 96.5%. Counties with outbreaks in Kansas include Gray with 25 cases, Haskell with 11 and and Stevens with seven. Vaccination rates in Gray County dropped 23 percentage points after the pandemic, from 94% to 71%. Haskell County dropped 18 percentage points to 65%. And Stevens County dropped 0.5 percentage points to 90.5%. Colorado's outbreak, which is linked to an international flight that landed at the Denver airport in mid-May, involves six cases: five in state residents and one out-of-state traveler. Two people who got measles live in Arapahoe County in the Denver metro, where the vaccination rate dropped 3.5 percentage points to 88.4%. Three others live in El Paso County, home to Colorado Springs, where the vaccination rate dropped 3.8 percentage points to 80% post-pandemic. Pre-pandemic data in North Dakota wasn't available to Johns Hopkins researchers, but they looked at rates from school years ending in 2022, 2023 and 2024. North Dakota's first outbreak started in Williams County, which now has 16 measles cases. In the timeframe researchers looked at, vaccination rates in Williams rose from 84.6% in 2022 to 87.7% in 2023, only to drop back to 83.5% in 2024. Cass County has seven cases, and its rate has stayed steady at about 92.7%, while Grand Forks County, which has 10 measles cases, dropped from 95.4% to 93.4%.
