IMPORTANCE: Traumatic brain injury (TBI) and vascular risk factors are associated with cognitive impairment, but it is unknown if individuals with vascular risk factors experience worse cognitive outcomes after TBI.

OBJECTIVE: To evaluate cognitive function among patients with TBI with vs without comorbid preinjury vascular risk factors.

DESIGN, SETTING, AND PARTICIPANTS: This prospective cohort study examined individuals with TBI enrolled in the Transforming Research and Clinical Knowledge in TBI (TRACK-TBI) Study between February 26, 2014, and August 8, 2018, with a 1-year follow-up. Analyses were conducted February 26, 2024, to May 29, 2025.

The Infected Diabetic Foot: Bacteraemia And Endocarditis Complicating Moderate And Severe Foot Infections, Mario C Reyes, Arthur N Tarricone, Mathew J Sideman, Michael C Siah, Bijan Najafi, Edgar J G Peters, Lawrence A Lavery

To identify the incidence of blood stream infections (BSIs) and endocarditis in patients with diabetic foot infections (DFIs), risk factors and clinical outcomes. A post hoc analysis of 280 patients using pooled patient level data from three RTCs. Blood cultures were drawn at time of admission for DFI. Deep intraoperative cultures were obtained from infected foot wounds. Data from the 12-month follow-up were used to determine clinical outcomes. 77.1% (N = 216) had blood cultures of which 15.7% (n = 34) had BSI. One patient (3.3%) had endocarditis. Risk factors for BSI included Charcot Neuroarthropathy history (20.6% vs. 7.1%, p …

The Infected Diabetic Foot: Incidence And Risk Factors For Dehiscence After Surgery For Diabetic Foot Infections, Lawrence A Lavery, Mario C Reyes, Bijan Najafi, Tyler L Coye, Jayer Chung, Michael C Siah, Arthur N Tarricone

Our objective was to assess the incidence, risk factors and clinical outcomes of dehiscence after foot surgery in diabetic patients. We used pooled patient‐level data from two randomised clinical trials with 240 diabetic patients who required foot surgery for infections. Most patients (n = 180, 75.0%) had surgical wound closure. We defined dehisced surgical wounds (DSW) when the surgical site was not completely epithelialized with no drainage after sutures/staples were removed with a 2‐week validation of healing. We evaluated the time to heal, re‐infection, re‐ulceration, hospital admissions and amputations. Moderate and severe infection was based on criteria of the …

The Infected Diabetic Foot: Risk Factors For Re-Infection After Treatment For Diabetic Foot Osteomyelitis, Lawrence A Lavery, Mario C Reyes, Bijan Najafi, Tyler L Coye, Matthew Sideman, Michael C Siah, Arthur N Tarricone

Our objective was to evaluate risk factors for re-infection in patients after treatment for diabetic foot osteomyelitis (OM). We used pooled patient level data from two RTCs that evaluated patients with diabetic foot infections. We evaluated 171 patients with OM. OM was confirmed with bone culture or histopathology. Data from the 12-month follow-up were used to determine clinical outcomes. Re-infection occurred in 47 (27.5%) patients. Risk factors for re-infection were Toe Brachial Index < 0.40 (25.7% vs. 9.8%, p = 0.02), skin perfusion pressure < 40 mmHg (6.3% vs. 5.9%, p = 0.04), wound healing (55.3% vs. 75.0%, p = 0.01), time to heal (156.0, 69.5-365 vs. 91.5, 38.8-365, p = 0.001), and history of MI (14.9% vs. 3.2%, p = 0.005). During 12-month follow-up, patients with re-infections were 198.8 times more likely to require a foot related hospitalisation (81.8% vs. 0.0%, p = 0.001), 10.4 times more likely have an all-cause hospitalisation (70.2% vs. 18.5%, p = 0.001) and 9.4 times more likely to need an amputation (36.2% vs. 5.6%, p = 0.001). Patients with re-infection had a significantly longer median length of hospitalisation (20.0, 13.5-34.5 vs. 14.0, 10.0-22.0, p = 0.003) and median length of antibiotic duration (55.0, 35.0-87.0 vs. 46.0, 22.8-68.0, p = 0.03). Patients with re-infection are less likely to heal and have more foot-related hospitalizations and amputations.

Towards A Remote Patient Monitoring Platform For Comprehensive Risk Evaluations For People With Diabetic Foot Ulcers, Gozde Cay, M G Finco, Jason Garcia, Jill L Mcnitt-Gray, David G Armstrong, Bijan Najafi

Diabetic foot ulcers (DFUs) significantly affect the lives of patients and increase the risk of hospital stays and amputation. We suggest a remote monitoring platform for better DFU care. This system uses digital health metrics (scaled from 0 to 10, where higher scores indicate a greater risk of slow healing) to provide a comprehensive overview through a visual interface. The platform features smart offloading devices that capture behavioral metrics such as offloading adherence, daily steps, and cadence. Coupled with remotely measurable frailty and phenotypic metrics, it offers an in-depth patient profile. Additional demographic data, characteristics of the wound, and clinical …
