Dr. Wier studies several key areas including HIV testing, the assessment of brain injuries in athletes, surgical education, and complications linked to heart surgery treatments. One significant aspect of his research is the evaluation of a new HIV test that accurately identifies infections, helping to control the spread of the virus. He also investigates how well current recovery assessments work for athletes after brain injuries, highlighting risks of returning to play too soon. In addition, he has explored new diagnoses for unexplained biliary pain, offering treatment options that can significantly relieve patient suffering. Lastly, he analyzes the use of specific medications in post-surgical settings to ensure patient safety.
Key findings
The Elecsys Duo HIV test achieved a perfect sensitivity rate of 100% and a specificity of 99.84%, making it highly effective for routine testing.
In a study of athletes with mild brain injuries, high levels of marinobufagenin indicated some were not fully recovered even with improved neurocognitive test scores.
Nineteen patients with normokinetic biliary dyskinesia treated with laparoscopic cholecystectomy had a success rate of 90% in symptom relief.
In a study of 292 patients recovering from heart surgery, some patients experienced toxic reactions to sodium nitroprusside, leading to serious complications.
Over half (52.3%) of critically ill patients with pulmonary artery catheters experienced irregular heartbeats, emphasizing the procedure's risks.

Publications in plain English
Real-World Clinical Performance Evaluation of a Fourth-Generation HIV Antigen/Antibody Differentiation Test.
2021
The journal of applied laboratory medicine
Krasowski MD, Wier D, Smith S, Riedel A, Lauseker-Hao Y +2 more
Plain English This study tested a new HIV test called the Elecsys Duo assay to see how well it detects the virus compared to an older test, the Abbott Architect assay. The Elecsys test correctly identified all positive cases with a perfect sensitivity rate of 100% and a high specificity rate of 99.84%. This is important because it means the Elecsys test can effectively identify HIV infections, including various strains, and can be used reliably in routine testing.
Who this helps: This benefits patients, healthcare providers, and public health efforts in controlling HIV transmission.
Comparison of Neurocognitive Testing and the Measurement of Marinobufagenin in Mild Traumatic Brain Injury: A Preliminary Report.
2015
Journal of experimental neuroscience
Oliver J, Abbas K, Lightfoot JT, Baskin K, Collins B +4 more
Plain English This study looked at how two different methods—neurocognitive testing (NCT) and measuring a biomarker called marinobufagenin (MBG)—can be used to assess recovery from mild brain injuries in athletes. Researchers found that even when NCT scores improved, some athletes still had high levels of MBG in their urine, indicating they weren't fully recovered. This is important because it suggests current return-to-play guidelines might not be safe enough for athletes.
Who this helps: This helps athletes and their healthcare providers make better decisions about returning to sports after a concussion.
A primer on standards setting as it applies to surgical education and credentialing.

Surgical endoscopy
Cendan J, Wier D, Behrns K
Plain English This study examined how new surgical technologies, like robotic surgery and single-incision methods, have changed the way surgeries are performed and assessed. Researchers found that these advancements can sometimes harm patients, emphasizing the need for strict evaluations before adopting new techniques. Establishing clear standards for assessing surgeons' knowledge and skills will improve patient safety and ensure that doctors are properly credentialed.
Who this helps: This helps patients and healthcare providers.
Normokinetic biliary dyskinesia: a novel diagnosis.
2012
Surgical endoscopy
DuCoin C, Faber R, Ilagan M, Ruderman W, Wier D
Plain English This study examined a new condition called normokinetic biliary dyskinesia in patients who experience biliary pain but have normal CCK-HIDA scan results. Out of 19 patients treated with laparoscopic cholecystectomy, 17 saw their symptoms completely disappear, leading to a 90% success rate in relieving pain. This finding is important because it offers a new diagnosis and treatment option for patients who have been enduring unexplained biliary pain without effective care.
Who this helps: Patients suffering from unexplained biliary pain.
Acute complications of pulmonary artery catheter insertion in critically ill patients.
1986
Critical care medicine
Patel C, Laboy V, Venus B, Mathru M, Wier D
Plain English The study looked at the complications that can occur when inserting a pulmonary artery catheter in 142 critically ill patients. It found that 1.4% had a collapsed lung (pneumothorax), 7.7% had punctures in their arteries, and more than half (52.3%) experienced irregular heartbeats, particularly those with complex heart issues. Understanding these risks is important for doctors to consider when deciding whether to use this type of catheter in patients.
Who this helps: This information benefits doctors and critically ill patients.
Use of sodium nitroprusside in post-coronary bypass surgery. A plea for conservatism.
1986
Chest
Patel CB, Laboy V, Venus B, Mathru M, Wier D
Plain English This study examined the effects of sodium nitroprusside (SNP), a medication used to lower blood pressure, in 292 patients recovering from heart surgery. It found that seven patients experienced toxic reactions to the drug, leading to complications like loss of consciousness and necessitating higher doses to control their blood pressure. The study highlights that using standard doses of SNP in seriously ill patients can be harmful and recommends caution in its use.
Who this helps: This helps doctors and healthcare providers in managing blood pressure for patients recovering from heart surgery.
