Alcohol withdrawal syndrome linked to worse surgical outcomes, higher costs

National study highlights need for perioperative screening and management to reduce complications

2025-07-28
(Press-News.org) Key Takeaways Among 3 million surgical patients, 0.5% developed alcohol withdrawal syndrome (AWS), with 0.2% experiencing severe delirium tremens (DT).  AWS was associated with a 37% higher risk of complications, including respiratory failure and sepsis, and a 40% increased mortality risk if DT occurred. Hospital stays were 5 days longer, and costs rose by $10,000 per patient with AWS, totaling $165 million in excess costs nationwide.  CHICAGO — Patients who develop alcohol withdrawal syndrome (AWS) after major surgery face significantly higher risks of complications, longer hospital stays, and increased health care costs, according to a study published in the Journal of the American College of Surgeons (JACS). The findings underscore the need for screening before surgery and targeted interventions. 

Using the National Inpatient Sample (2016–2019), researchers analyzed data from 3 million adults who underwent major operations, including colectomy, cardiac surgery, and liver resection. Among them, 16,504 (0.5%) were diagnosed with AWS, including 6,591 (0.2%) with life-threatening delirium tremens (DT). DT is a severe form of alcohol withdrawal that can include shaking, confusion, and hallucinations. 

“AWS is a preventable complication, yet it’s often overlooked in surgical planning,” said lead author Timothy M. Pawlik, MD, PhD, MPH, FACS, surgeon-in-chief at the Ohio State University Wexner Medical Center. “Our study shows that proactive screening and multidisciplinary care — involving surgeons, social workers, and addiction specialists — can save lives and reduce costs.” 

Key Findings   High-risk patients: AWS was more common in men (median age 61), Medicaid recipients, and those with substance use disorders. Complications: AWS doubled the risk of respiratory failure and sepsis. DT increased mortality by 40%. Economic impact: Adjusted hospitalization costs rose by $10,030 per patient with AWS; DT added another $5,300.   Interventions for the Future  The study highlights actionable strategies to improve outcomes:

Preoperative screening: Use validated tools (e.g., AUDIT-C) to identify high-risk patients. Judgment-free care: “This is a disease, not a moral failing,” stressed Dr. Pawlik. “We need honest conversations to tailor treatment.” Early intervention: For patients at risk, preventative medications (e.g., benzodiazepines) and ICU-level monitoring may prevent DT.  “A patient recovering from major surgery shouldn’t also battle withdrawal,” said Dr. Pawlik, recalling a case where AWS led to aspiration pneumonia post-surgery. “We can change this by addressing alcohol use before surgery and ensuring safer recovery environments.” 

Limtations: The study relied on administrative data, potentially underestimating AWS incidence. Long-term outcomes and treatment specifics (e.g., benzodiazepine use) were not assessed.

Detecting a potential behavioral biomarker for Parkinson’s disease in mice

2025-07-28
Detecting early rising Parkinson’s disease (PD) symptoms could improve treatment outcomes by enabling earlier treatment interventions. In a new eNeuro paper, Daniil Berezhnoi, from Georgetown University, and colleagues used machine learning technology to detect subtle, early rising behavioral changes in mouse models of PD. The researchers also evaluated whether Levodopa, the primary approved treatment for PD, can effectively treat these symptoms.  Berezhnoi et al. used a previously developed motion sequencing platform to evaluate movements of different ...

Expectations about pain influence the experience in different ways

2025-07-28
Previous expectations can influence how much pain people eventually feel. These expectations can be shaped by external cues or by verbal information from clinicians about how treatments might relieve pain. Led by Lauren Atlas, researchers from the National Institute of Health explored if and how distinct ways of shaping expectations differentially influence physically hurtful experiences.  In their JNeurosci paper, the researchers present their findings from 40 healthy volunteers who rated how hurt they were following painful ...

Landmark sleep study links objective sleep patterns with 172 diseases—regularity matters more than duration

CD4+ T cell-mediated immune drift in biologic treatment of inflammatory skin diseases

2025-07-28
Immune-inflammatory skin diseases (e.g., psoriasis, atopic dermatitis) involve dysregulation of CD4+ T-cell subsets (Th1/Th2/Th17/Treg) and cytokine networks (IL-17/IL-23/IL-4). Biologics targeting specific pathways—TNF-α, IL-17, IL-12/23, IL-4/13, PD-1/PD-L1—revolutionize treatment but trigger immune drift, shifting CD4+ T-cell polarization and causing adverse skin reactions. This review synthesizes mechanisms, clinical manifestations, and management strategies. Mechanisms of Immune Drift by Biologic Class (Summarized in Table 1) 1. TNF-α Inhibitors (Etanercept, Infliximab, Adalimumab) Mechanism: Blocking ...

There’s something in the air

2025-07-28
Researchers at the University of Tokyo explored how female body odor can influence behaviors in men. They found certain scent compounds in female body odor increased during ovulation and can subtly influence how men feel. When these scents were added to armpit odor samples, men rated them as more pleasant and faces associated with the samples as more attractive. The scents also seemed to reduce stress. The team states this is not evidence of pheromones in humans, but that smell might subtly shape how we people interact. While they’re a common staple of pop culture, especially in romantic comedies, pheromones, behavior-altering ...

New system dramatically speeds the search for polymer materials

2025-07-28
Cambridge, MA – Scientists often seek new materials derived from polymers. Rather than starting a polymer search from scratch, they save time and money by blending existing polymers to achieve desired properties. But identifying the best blend is a thorny problem. Not only is there a practically limitless number of potential combinations, but polymers interact in complex ways, so the properties of a new blend are challenging to predict. To accelerate the discovery of new materials, MIT researchers ...
