Effect of Etomidate vs Propofol for Total Intravenous Anesthesia on Major Postoperative Complications in Older Patients
Findings of this trial indicate that etomidate anesthesia does not increase postoperative morbidity in older patients compared with propofol.
KEY FINDINGS: Results of this trial showed that, compared with propofol, etomidate anesthesia did not increase overall major in-hospital morbidity after abdominal surgery in older patients, although it induced transient adrenocortical suppression.
BACKGROUND: Aim of this study is to test the primary hypothesis that etomidate vs propofol for anesthesia does not increase in-hospital morbidity after abdominal surgery in older patients.
DETAILS: This multicenter, parallel-group, noninferiority randomized clinical trial (Etomidate vs Propofol for In-hospital Complications [EPIC]) was conducted between August 15, 2017, and November 20, 2020, at 22 tertiary hospitals in China. Participants were aged 65 to 80 years and were scheduled for elective abdominal surgery. Patients and outcome assessors were blinded to group allocation. Data analysis followed a modified intention-to-treat principle. Primary outcome was a composite of major in-hospital postoperative complications (with a noninferiority margin of 3%). Secondary outcomes included intraoperative hemodynamic measurements; postoperative adrenocortical hormone levels; self-reported postoperative pain, nausea, and vomiting; and mortality at postoperative months 6 and 12. A total of 1944 participants were randomized, of whom 1917 (98.6%) completed the trial. Patients were randomized to the etomidate group (n = 967; mean [SD] age, 70.3 [4.0] years; 578 men [59.8%]) or propofol group (n = 950; mean [SD] age, 70.6 [4.2] years; 533 men [56.1%]). The primary end point occurred in 90 of 967 patients (9.3%) in the etomidate group and 83 of 950 patients (8.7%) in the propofol group, which met the noninferiority criterion (risk difference [RD], 0.6%; 95% CI, -1.6% to 2.7%; P = .66). In the etomidate group, mean (SD) cortisol levels were lower at the end of surgery (4.8 [2.7] µg/dL vs 6.1 [3.4] µg/dL; P < .001), and mean (SD) aldosterone levels were lower at the end of surgery (0.13 [0.05] ng/dL vs 0.15 [0.07] ng/dL; P = .02) and on postoperative day 1 (0.14 [0.04] ng/dL vs 0.16 [0.06] ng/dL; P = .001) compared with the propofol group. No difference in mortality was observed between the etomidate and propofol groups at postoperative month 6 (2.2% vs 3.0%; RD, -0.8%; 95% CI, -2.2% to 0.7%) and 12 (3.3% vs 3.9%; RD, -0.6%; 95% CI, -2.3% to 1.0%). More patients had pneumonia in the etomidate group than in the propofol group (2.0% vs 0.3%; RD, 1.7%; 95% CI, 0.7% to 2.8%; P = .001). Results were consistent in the per-protocol population.

Prompt and Intensive Antiviral Chemoprophylaxis in Nursing Home Influenza Outbreaks
Findings suggest intensive chemoprophylaxis of 70% or more of residents in response to influenza outbreaks in NHs within the first 2 days is associated with a lower 14-day risk of hospitalization among residents, with additional evidence to support a benefit when 60% or more or 80% or more of residents receive chemoprophylaxis. These findings could strengthen evidence-based recommendations to inform best practices in managing influenza outbreaks in NHs.
KEY FINDINGS: Study results suggest that clinicians should initiate antiviral chemoprophylaxis for at least 70% of eligible NH residents within 2 days of outbreak detection to lower risk of hospitalization.
BACKGROUND: Influenza outbreaks in nursing homes (NHs) pose a substantial threat to older adults, often resulting in morbidity and mortality. The Centers for Disease Control and Prevention (CDC) and the Infectious Diseases Society of America (IDSA) recommend prompt postexposure prophylaxis, also termed chemoprophylaxis or prophylaxis with oseltamivir, for all residents who are not ill to limit influenza spread in NHs. Purpose of the study is to examine whether initiating antiviral chemoprophylaxis for 70% or more of eligible NH residents within 2 days of influenza outbreak detection is associated with lower all-cause mortality and hospitalization at 14 and 30 days.
DETAILS: Retrospective cohort study using a sequential cluster-randomized target trial emulation and randomize-censor-weight approach for influenza outbreaks (September 1, 2018-May 31, 2022) in 12 US NH corporations. Eligibility criteria were age 18 years or older, present on the outbreak-detection day, no antiviral use in the preceding 7 days, no influenza in the past 14 days, and complete baseline data. Residents were followed up until hospitalization or death, an NH discharge to a nonacute-care location, or the end of follow-up. Data were analyzed from February 2023 to January 2026.

Exposures: Intensive antiviral chemoprophylaxis with oseltamivir (>=70% of eligible residents within 2 days of outbreak detection) or nonintensive antiviral chemoprophylaxis (0% to <70% of eligible residents).
Outcomes were all-cause death and hospitalizations within 14 and 30 days of outbreak detection. Discrete-time hazard models with pooled logistic regression were applied to estimate weighted risks, risk differences (RDs), and risk ratios (RRs).
Among 404 outbreaks in 318 NHs, 35,086 resident-trial observations (29,683 residents; median age 78 [IQR, 68- 86] years; 60% women; 81% White; 76% vaccinated) met eligibility criteria. Intensive oseltamivir prophylaxis was randomized to 17,155 observations; 17,931 were randomized to nonintensive care. At 14 days, intensive prophylaxis vs nonintensive yielded an RD of -0.06% (95% CI, -0.73% to 0.93%) and an RR of 0.96 (95% CI, 0.56-1.57) for death, and an RD of -0.96% (95% CI, -1.78% to -0.19%) and an RR of 0.79 (95% CI, 0.64-0.96) for hospitalization. At 30 days, the hospitalization differences persisted but were less precise and there continued to be no difference in death.

The Association between Socioeconomic Status and Structural or Functional Baseline Measurements for Patients Receiving a Trabeculectomy
Lower SES is associated with worse optic nerve damage and VF performance at presentation for eyes that eventually undergo trabeculectomy surgery.
KEY FINDINGS: Lower SES is associated with worse optic nerve damage and VF performance at presentation for eyes that eventually undergo trabeculectomy surgery.
BACKGROUND: Objective of this study is to evaluate the association between socioeconomic status (SES; represented by a patient's neighborhood area deprivation index) and structural and functional measurements of the eye at initial presentation for those who eventually underwent trabeculectomy. Authors identify patients who underwent a trabeculectomy and had at least 1 OCT scan and 1 visual field (VF) test before undergoing surgery. Patients of any age with either progressing glaucoma or uncontrolled intraocular pressure, or both, who underwent a trabeculectomy and were a part of the DOMAIN cohort study were included.
DETAILS: Authors use a subject's first recorded OCT scan and VF test to obtain baseline structural and functional measurements. We next use patient addresses to determine their census block, which is then matched to the corresponding proxy for SES. Univariate and multivariate regressions controlling for race, age, and gender were used to analyze the associations between SES and structural and functional measurements at baseline. Among the 154 eyes in the study, we find that living in an area with greater deprivation is associated with worse structural (larger cup volumes [CVs], thinner retinal nerve fiber layer, and ganglion cell-inner plexiform layer) and functional (lower visual field index [VFI] and mean deviation [MD]) measures at baseline. However, these associations only remained statistically significant in the multivariate analysis for CV, VFI, and MD after controlling for a patient's race, gender, and age. In addition, when comparing those living in the best and worst neighborhoods, we find that living in the area with the highest decile level of deprivation is associated with a 6.63 dB lower MD at presentation compared to those living in areas with the least deprivation.

Enhanced Travel Restrictions Implemented Following Ebola Outbreak
U.S. travelers from DRC, South Sudan, and Uganda must undergo enhanced Ebola screening at Dulles Airport. Travel restrictions prevent foreign nationals who visited these countries in the past three weeks from entering the U.S. The Ebola outbreak in the DRC has caused over 600 suspected cases and 148 deaths, with transmission possibly starting in early April. No Ebola cases have been reported in the U.S., and the CDC considers the domestic risk to be low. Efforts are focused on containment, transmission chain tracing, and public education, as there is no available vaccine or treatment for the current strain.
KEY FINDINGS: A primary challenge in this specific outbreak is the nature of the causative agent, the Bundibugyo virus. Unlike the more common Zaire ebolavirus, there is currently no licensed vaccine or specific, FDA-approved treatment effective against the Bundibugyo strain. Consequently, the public health response relies entirely on traditional containment strategies. These include rapid case detection, patient isolation, meticulous contact tracing, the promotion of infection prevention and control practices, safe burial procedures, and robust community education to curb transmission chains. Researchers are currently evaluating whether existing therapeutic candidates or vaccine platforms could be adapted for emergency use, though clinical implementation remains under investigation.
BACKGROUND: In response to a burgeoning outbreak of Ebola virus disease caused by the Bundibugyo strain, the United States government has enacted new travel and entry protocols. The current outbreak, centered in the Democratic Republic of the Congo (DRC) and involving cases in South Sudan and Uganda, has prompted international health authorities to declare a public health emergency. As global travel remains a potential vector for the international spread of the virus, the U.S. government has taken proactive measures to bolster domestic defense against the introduction of the pathogen.
DETAILS: Effective May 2026, the U.S. Centers for Disease Control and Prevention (CDC) and the Department of Homeland Security have implemented stringent travel requirements. Foreign nationals who have visited the DRC, South Sudan, or Uganda within the 21 days prior to their arrival are temporarily suspended from entry into the United States. Furthermore, all U.S. citizens, nationals, and lawful permanent residents returning from these three countries must route their travel through specifically designated entry points, including Washington-Dulles International Airport, where they are subject to enhanced public health screening. These measures include health questionnaires, temperature checks using non-contact technology, and verification of contact information to facilitate monitoring for symptoms over a 21-day period following departure from the affected regions. While the current outbreak is significant—with reports indicating nearly 500 suspected cases and more than 130 deaths since the official declaration on May 15—the domestic risk to the United States is currently assessed by the CDC as low. As of late May 2026, no suspected, probable, or confirmed cases of Ebola have been reported within the United States. Authorities are maintaining a state of high readiness, with regional hospitals and state health departments prepared to manage and isolate any potential symptomatic travelers identified through the screening process.

Efficacy of Low-Dose Oral Isotretinoin Combined with Fractional Microneedle Radiofrequency Versus Low-Dose Oral Isotretinoin Monotherapy in the Treatment of Moderate-To-Severe Acne Vulgaris
Early active treatment with isotretinoin and FMRF is safe and better than isotretinoin monotherapy over 44 weeks regarding severity, reduced erythema, and improved surface roughness in moderate-to-severe acne vulgaris. This encourages early and effective treatment of acne to mitigate acne scarring and improve patients' quality of life.
Summary
A Randomized Controlled Comparative Study
[Posted 19/May/2026]
AUDIENCE: General Surgery, Family Medicine
KEY FINDINGS: Early active treatment with isotretinoin and FMRF is safe and better than isotretinoin monotherapy over 44 weeks regarding severity, reduced erythema, and improved surface roughness in moderate-to-severe acne vulgaris. This encourages early and effective treatment of acne to mitigate acne scarring and improve patients' quality of life.
BACKGROUND: Oral isotretinoin is the standard therapy for severe acne. However, scarring may persist. Fractional microneedling radiofrequency (FMRF) improves both inflammatory lesions and scars with minimal downtime. In this study, we compare isotretinoin monotherapy and concurrent isotretinoin and FMRF for active acne regarding clinical outcomes. The GAGS scores of isotretinoin and FMRF were significantly lower than those of isotretinoin monotherapy from weeks 12-44 (-79.69% vs. -60.34% at week 44, respectively; p < 0.001). Isotretinoin and FMRF showed significantly greater lesion count reductions than isotretinoin monotherapy at follow-up visits from weeks 12-44. Isotretinoin and FMRF showed significantly lower hemoglobin levels than isotretinoin monotherapy at weeks 32 and 44 (p = 0.029 and p < 0.001, respectively). Skin surface roughness improved substantially and persistently from week 12-44.
DETAILS: In this parallel two-group comparative study, patients received either low-dose isotretinoin monotherapy for 20 weeks (n = 34) or low-dose isotretinoin concurrently with 5 monthly FMRF sessions (n = 36). Outcomes were assessed at baseline and weeks 12, 20, 24, 32, and 44. The primary endpoints were Global Acne Grading System (GAGS) scores and inflammatory/non-inflammatory lesion counts. Secondary endpoints were hemoglobin indices and skin roughness.
