BACKGROUND Guidelines and evidence related to antibiotic prophylaxis in dermatologic surgery have evolved since the authors' previously published advisory statement. OBJECTIVE To provide an updated advisory statement on antibiotic prophylaxis in dermatologic surgery as guided by updated recommendations from the American Heart Association and the American Dental Association with the American Academy of Orthopaedic Surgeons guidelines. METHODS A structured literature review was performed. A multidisciplinary team of specialists from dermatologic surgery, infectious diseases, and pharmacy were convened to review up-to-date data and develop updated comprehensive evidence-based recommendations. RESULTS Consistent with the previous advisory statement, prophylactic antibiotics are recommended for patients with high-risk cardiac or prosthetic joint conditions, when the dermatologic surgical site is infected or if the procedure breaches the mucosa. Significant changes were made for prophylaxis of surgical site infection. Updated recommendations were made regarding antibiotic selection in penicillin-allergic patients and intraoperative use of intraincisional clindamycin in the local anesthetic. LIMITATIONS Reviewed data are predominantly limited to retrospective data. CONCLUSION Recommendations regarding antibiotic prophylaxis around dermatologic surgery are evolving as new data and practices are introduced. The 2025 advisory statement provides the latest recommendations for appropriate use of antibiotic prophylaxis in dermatologic surgery.

Abstract Background Anti‐M antibodies were described as rarely eliciting hemolytic disease of the fetus and newborn (HDFN) in pregnancy. More recent literature, primarily from Asia, reports severe HDFN attributed to maternal anti‐M. The objective of this study is to determine if there is a difference in the frequency and/or severity of anti‐M HDFN among subjects who self‐report as Asian compared to non‐Asian. Methods Retrospective data were collected from 18 sites. Fetuses/neonates affected by HDFN were categorized as unaffected, mild, moderate, or severe based on clinical management and outcomes. Results Anti‐M was identified in 557 obstetric patients. Among 332 neonates with complete data for analysis, anti‐M was detected in isolation during the pregnancies of 210 (63.3%) neonates; 198 (94.3%) were unaffected by HDFN. The overall frequency of HDFN was 6.5% (2/31) in Asian patients and 5.6% (10/179) in non‐Asian patients. The frequency of severe HDFN was 6.5% (2/31) among Asian patients and 0.6% (1/179) among non‐Asian patients. Among non‐Asian patients, eight (4.5%) were mild and one (0.6%) was moderate. Of 63 pregnancies with anti‐M and ABO incompatibility, 6 (9.5%) were associated with mild HDFN and 57 (90.5%) were unaffected. Of 49 pregnancies with anti‐M and non‐ABO antibody(s), 6 (12.2%) were associated with mild HDFN and 43 (87.8%) were unaffected. One case (10.0%) of HDFN (mild) occurred in the presence of anti‐M, additional antibody(s), and ABO incompatibility. Conclusion In this study, severe anti‐M HDFN was rare in non‐Asian subjects. There is a signal that Asian patients are at greater risk for severe anti‐M HDFN.

ABSTRACT Metabolic dysfunction‐associated steatotic liver disease (MASLD) represents a key hepatic manifestation of obesity and systemic metabolic dysfunction and is a leading cause of chronic liver disease worldwide. Obesity‐driven mechanisms, including adipose tissue dysfunction, insulin resistance and increased free fatty acid flux to the liver, promote ectopic lipid accumulation and lipotoxic injury. These processes trigger mitochondrial and endoplasmic reticulum stress, inflammation, immune activation and disturbances in the gut–liver axis, driving disease progression from simple steatosis to metabolic dysfunction–associated steatohepatitis, fibrosis and cirrhosis. MASLD is a highly heterogeneous condition, with differences in fat distribution, body composition and genetic susceptibility giving rise to distinct clinical phenotypes, including lean and non‐lean MASLD, which have important implications for disease risk, progression and therapeutic response. Clinical outcomes are determined primarily by fibrosis stage, which represents the strongest predictor of liver‐related and all‐cause mortality, underscoring the importance of early disease recognition and risk stratification. Therapeutic strategies, therefore, increasingly target upstream metabolic drivers rather than hepatic steatosis alone. Lifestyle interventions remain foundational but are often limited by challenges in long‐term adherence. Pharmacologic therapies, particularly incretin‐based agents such as glucagon‐like peptide‐1 receptor agonists and dual incretin agonists, as well as bariatric and endoscopic metabolic procedures, have demonstrated substantial metabolic and hepatic benefits. Recognition of disease heterogeneity supports phenotype‐guided approaches that integrate metabolic risk, adiposity, body composition and fibrosis assessment to personalise treatment strategies and improve long‐term outcomes across the MASLD spectrum.

ABSTRACT Introduction/Aims Eplontersen is approved in multiple regions for adults with hereditary transthyretin amyloidosis with polyneuropathy (ATTRv‐PN). This exploratory analysis was conducted to evaluate the treatment effect of eplontersen by sex in patients with ATTRv‐PN from the NEURO‐TTRansform trial (NCT04136184). Methods Participants in NEURO‐TTRansform who received ≥ 1 dose of eplontersen were included in this analysis; participants in the inotersen reference group who switched to eplontersen were excluded. Eplontersen was evaluated in the overall patient population and in a subgroup with cardiomyopathy. Change from baseline in the NEURO‐TTRansform primary endpoints of serum transthyretin (TTR) levels to Week 65, modified Neuropathy Impairment Score +7 (mNIS+7) composite score to Week 66, and Norfolk Quality of Life‐Diabetic Neuropathy (Norfolk QoL‐DN) total score to Week 66 were evaluated. A historical placebo group from the NEURO‐TTR trial (NCT01737398) was included as a control. Results The eplontersen group comprised 100 (69.4%) male and 44 (30.6%) female patients. The placebo group comprised 41 (68.3%) male and 19 (31.7%) female patients. For both sexes, treatment with eplontersen decreased serum TTR levels by > 80% (vs. reductions of 3%–13% with placebo), maintained mNIS+7 scores, and improved Norfolk QoL‐DN scores (vs. deterioration with placebo). The treatment effect of eplontersen was similar in male and female patients with cardiomyopathy. Discussion Eplontersen halted neuropathy impairment and improved quality of life versus placebo to a similar degree in both male and female patients with ATTRv‐PN, including those with cardiomyopathy. These findings support the use of eplontersen as an effective treatment for ATTRv‐PN regardless of sex.

Abstract Background X‐ray Induced Acoustic Computed Tomography (XACT) is an emerging imaging technique that provides 3D volumetric images from a single projection by detecting X‐ray‐induced acoustic (XA) waves with ultrasound (US) transducers. Unlike MRI or CT, XACT enables real‐time 3D imaging without long acquisition times, 2D limitations, or motion artifacts from mechanical rotation. Furthermore, when integrated with conventional pulse‐echo US through time‐sequenced operation, XACT provides complementary soft‐tissue contrast, establishing it as a promising platform for dynamic interventional radiology (IR) guidance. Purpose This study aims to evaluate the feasibility of XACT as a novel imaging tool for IR, specifically for guiding needle placement and monitoring contrast agent dynamics. Methods We developed a 3D XACT imaging system equipped with a 256‐element 2D matrix array and a portable X‐ray tube to visualize needle insertion and contrast agent dynamics. To capture both needle position and soft tissue anatomy, we integrated a dual‐modality system combining XACT with pulse‐echo US using a 128‐element linear US array. Experiments were conducted on both tissue‐mimic phantoms and soft tissue samples. GPU‐accelerated algorithm has been developed for 3D XACT image reconstruction. Results The results demonstrate the 3D capabilities of XACT imaging for interventional procedures, including monitoring of needle placement and tracking of contrast agent dynamics. The imaging speed reached up to 3∼4 s per frame, constrained by the repetition rate of the X‐ray source and signal to noise ratio. The dual‐modality approach provided clear visualization of the needle's position and the surrounding soft tissue structures, achieving imaging resolution around 2 mm. Conclusions This study demonstrates that XACT imaging is feasible to be used for IR. Its 3D imaging capability with faster imaging speed would be an alternative to cone beam CT and its capability to combine US imaging will provide richer information for soft tissue
