Predictors of Internal Rotation after Reverse Shoulder Arthroplasty.

2023

The archives of bone and joint surgery

Gibian JT, Sokrab R, Hill JR, Keener JD, Zmistowski BM

Plain English
This study examined how different factors influence internal rotation of the shoulder after a specific type of surgery called reverse shoulder arthroplasty. It found that only 32.4% of patients had sufficient internal rotation a year after the surgery, an improvement from 20.4% before the procedure. Important factors that helped predict better internal rotation included being female, having a lower body weight, and having good movement in other directions after the surgery. Who this helps: This research benefits patients undergoing shoulder surgery and their doctors by identifying factors that can lead to better recovery outcomes.

Interobserver and Intraobserver Reliability of the Sirveaux Classification of Scapular Notching After Reverse Total Shoulder Arthroplasty.

2022

Orthopedics

Heckmann ND, McKnight B, Chen XT, Chung BC, Hill JR +3 more

Plain English
This study examined how consistently doctors can use the Sirveaux classification system to rate scapular notching, a common issue after a specific type of shoulder surgery. Over 50 shoulder surgeons graded 10 images of notching and then re-evaluated them after 6 weeks. The results showed only fair agreement between different doctors (with a score of 0.2437) and moderate consistency when the same doctor graded the images again (with a score of 0.4763), suggesting that doctors might struggle to agree on severity levels. This matters because clear communication about patient conditions is crucial for effective treatment and research. Who this helps: This helps patients and doctors who rely on accurate assessment of shoulder surgery outcomes.

Venetoclax: A Novel Therapeutic Agent for CLL with CNS Involvement.

2022

Case reports in oncology

Karbhari N, Lara-Martinez H, Hill JM

Plain English
This study looked at how venetoclax, a new drug, treated a 68-year-old woman with chronic lymphocytic leukemia (CLL) that had spread to her brain, causing severe headaches. After her previous treatment with another drug failed to work, adding venetoclax successfully cleared the cancer from her cerebrospinal fluid. This finding is important because it suggests venetoclax may be an effective option for treating CLL that affects the central nervous system. Who this helps: This helps patients with CLL and brain involvement.

Overview of Cochrane Systematic Reviews of Rehabilitation Interventions for Persons with Traumatic Brain Injury: A Mapping Synthesis.

2022

Journal of clinical medicine

Young VM, Hill JR, Patrini M, Negrini S, Arienti C

Plain English
This study looked at various rehabilitation methods for people who have suffered traumatic brain injuries by analyzing systematic reviews published between 2009 and 2021. It found that out of 19 comparisons of different treatments, only 3% were considered high quality, and most (54%) had low quality evidence, suggesting that the effectiveness of many recommended therapies is uncertain. This matters because, despite the need for better rehabilitation options, few treatments have shown significant improvements in recovery outcomes, like returning to work. Who this helps: This helps patients with traumatic brain injuries and their caregivers.

Mechanical and Microstructural Properties of Meniscus Roots Vary by Location.

2022

The American journal of sports medicine

Chang PS, Solon LF, Lake SP, Castile RM, Hill JR +1 more

Plain English
This study looked at the meniscus roots in the knees to understand how their strength and structure vary depending on their location. Researchers tested samples from 22 cadavers and found that the front roots are stronger than those at the back, with the anterior roots being significantly more robust. Specifically, anterior roots showed much higher strength values than posterior roots (with p-values less than 0.0001), and the lateral roots were stronger than medial ones, indicating that root location plays a critical role in injury susceptibility. Who this helps: This benefits doctors treating knee injuries, helping them better understand which meniscus roots are more likely to tear and how to approach treatment.

The PROMISE Minimal Risk Score Improves Risk Classification of Symptomatic Patients With Suspected CAD.

2022

JACC. Cardiovascular imaging

Rasmussen LD, Fordyce CB, Nissen L, Hill CL, Alhanti B +5 more

Plain English
This study looked at a method called the PROMISE Minimal Risk Score (PMRS) to better assess patients who might have coronary artery disease (CAD). The researchers found that using a PMRS value of 34% or higher correctly identified 442 out of 1,386 patients (about 31.9%) as being at low risk for obstructive CAD, with only a 3.2% chance of having the disease compared to a 7.1% rate in those who weren't down-classified. By combining this new scoring method with traditional risk assessments, doctors can more accurately identify patients who do not need further tests, potentially reducing unnecessary procedures. Who this helps: This helps patients suspected of having coronary artery disease, allowing them to avoid unnecessary tests and treatments.

2022

The Journal of hand surgery

Hill JR, Hong Z, Wall LB

Plain English
This study looked at how kinematic motion analysis (KMA), a method used primarily for walking assessments, might be applied to analyze issues with arm and hand movements. The researchers found that while KMA shows promise for evaluating upper body conditions, widespread use is limited due to the need for standardized methods and lower costs. Improving KMA for upper extremities could greatly enhance diagnosis and treatment options for patients with arm problems. Who this helps: Patients with upper limb disorders and their healthcare providers.
