Background And Objectives: Testosterone deficiency is associated with mortality in patients with heart failure; however, its effects on patients undergoing Left Ventricular Assist Device (LVAD) implantation are unclear. We investigated the role of total testosterone (TT) and free testosterone (FT) levels on mortality undergoing LVAD implantation.
Methods: Between December 2010 and December 2014, 101 consecutive male patients who underwent LVAD implantation and had plasma testosterone measurement (TT and FT) in the last month before operation were included in the study. Demographics, follow-up, and mortality data were analyzed retrospectively.
Results: The mean age of the patients was 51.7 ± 11 years. TT and FT levels were in the below normal range of 31.6% (n = 32) and 65.3% (n = 66) of the patients, respectively. The mean follow-up time was 355 ± 268 days, and 32 (31%) patients died during follow-up. Cumulative survival rates were significantly worse in patients with low TT and FT than patients in the normal range (P < .001 and P = .029, respectively). Multivariate analysis after adjustment for clinical variables, age, albumin, C-reactive protein, total cholesterol, chronic kidney disease, diabetes mellitus (DM), and leukocytosis showed that low TT and FT were independently associated with poor survival (HR, 3.680; 95% CI, 1.615-8.385 P = .002 and HR, 3.816; 95% CI, 1.279-11.383, P = .016, respectively).
Conclusion: Low TT and FT levels were independent risk factors for mortality in patients with LVAD.

The Management of Upper-Extremity Xylazine-Associated Wounds.
J Hand Surg Am
January 2025
Cooper University Hospital, Camden, NJ.
Purpose: Xylazine has been associated with necrotic soft tissue wounds that have placed a challenging burden on patients who inject drugs in the Philadelphia region's health care system over the last few years. An analysis of our initial experience is being presented to guide future treatment and directions for future research.
Methods: A retrospective review of 55 patients with patient-reported xylazine use and associated upper-extremity wounds at a single institution was performed.

Introduction: Unmet health care needs are seen as a key indicator of equity in access to health care. With younger people, they can lead to poorer health outcomes in adulthood, and in older people they can be associated with an increased risk of mortality. The presence of a disability is considered a risk factor for unmet needs.

Department of Epidemiology, Johns Hopkins Bloomberg School of Public Health, Baltimore, MD; The Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, Baltimore, MD.
Objective: To determine the association between concurrent statin use with immune checkpoint inhibitors (ICIs) and lung cancer-specific and overall mortality in patients with nonsmall cell lung cancer (NSCLC).
Materials And Methods: SEER-Medicare was used to conduct a retrospective study of Medicare beneficiaries ≥65 years of age diagnosed with NSCLC between 2007 and 2017 treated with an ICI. Patients were followed from date of first ICI claim until death, 1 month from last ICI claim, or 12/31/2018, whichever came first.
