AI Article Synopsis
- Dexamethasone (DEX) is a medicine that may help reduce blood clots after knee or hip surgery in patients with a history of blood clots.
- A study looked at over 70,000 patients who had this surgery, comparing those who received DEX with those who didn't.
- Patients who took DEX had fewer blood clots and shorter hospital stays, but there were no differences in infections between the two groups.
Article Abstract
Background: Dexamethasone (DEX) has demonstrated promise with respect to decreasing postoperative thromboembolic complications following total joint arthroplasty (TJA). Therefore, the aim of this study was to investigate the effects of perioperative intravenous DEX on rates of pulmonary embolism (PE) and deep vein thrombosis (DVT) after primary TJA in patients who have a history of venous thromboembolism (VTE).
Methods: Patients who have a history of VTE who underwent primary elective TJA from 2015 to 2021 were identified using a commercial health care database. Patients were divided based on receipt of perioperative intravenous DEX [DEX(+) versus DEX(-)] on the day of index TJA. Patient demographics and hospital factors were collected. The 90-day risk of postoperative complications, readmission, and in-hospital mortality were compared.
Results: Overall, 70,147 patients who had a history of VTE underwent TJA, of which 40,607 (57.89%) received DEX and 29,540 (42.11%) did not. The DEX(+) patients were younger (67 ± 9.8 versus 68 ± 9.9 years, P < .001) and had a significantly shorter length of stay compared to the DEX(-) patients (1.8 ± 1.6 versus 2.2 ± 1.8 days, P < .001). The DEX(+) patients demonstrated lower rates of PE (1.37 versus 1.75%, P < .001) and DVT (2.37 versus 3.01%, P < .001) compared to DEX(-) patients. The DEX(+) patients experienced a lower risk of PE (adjusted odds ratio: 0.78, 95% confidence interval: 0.66 to 0.93, P = .006) and DVT (adjusted odds ratio: 0.84, 95% confidence interval: 0.74 to 0.95, P = .006) compared to DEX(-) patients. The DEX(+) patients demonstrated no differences in the odds of surgical site infection, periprosthetic joint infection, or sepsis compared to the DEX(-) patients (P > .05).
Conclusions: The administration of DEX was associated with a decreased risk of PE and DVT in patients who have a history of VTE who underwent TJA. These data warrant further study investigating the postoperative benefits of perioperative DEX administration for high-risk patients undergoing TJA.
Level Of Evidence: Level III.

Background & Aims: Hepatic encephalopathy (HE), one of the most serious prognostic factors for mortality in alcohol-related cirrhosis (ALD cirrhosis), is not recorded in Danish healthcare registries. However, treatment of HE with lactulose, the universal first-line treatment, can be identified through data on filled prescriptions. This study aimed to investigate if lactulose can be used as a surrogate marker of HE.

Epiphany Dermatology, Dallas, TX, USA.
Knowledge on the effect of different nicotine consumption modalities on dermatologic surgical outcomes is limited, with conflicting conclusions. Cigarette smoking is known to adversely affect outcomes, but the impact of other nicotine consumption modalities like cigars, smokeless tobacco, and nicotine replacement therapy (NRT) is less understood. Our objective was to evaluate the impact of various nicotine consumption modalities on complication rates after Mohs micrographic surgery (MMS).
