RESUMEN
OBJECTIVE: Evaluate days alive and out of the hospital (DAOH) as an outcome measure after orthotopic heart transplantation in patients with mechanical circulatory support (MCS) as a bridge to transplant compared to those patients without prior MCS. DESIGN: A retrospective observational study of adult patients who underwent cardiac transplantation between January 1, 2015, and January 1, 2020. The primary outcome was DAOH at 365 days (DAOH365) after an orthotopic heart transplant. A Poisson regression model was fitted to detect the association between independent variables and DAOH365. SETTING: An academic tertiary referral center. PARTICIPANTS: A total of 235 heart transplant patients were included-103 MCS as a bridge to transplant patients, and 132 direct orthotopic heart transplants without prior MCS. MEASUREMENTS AND MAIN RESULTS: The median DAOH365 for the entire cohort was 348 days (IQR 335.0-354.0). There was no difference in DAOH365 between the MCS patients and patients without MCS (347.0 days [IQR 336.0-353.0] v 348.0 days [IQR 334.0-354.0], p = 0.43). Multivariate analysis identified patients who underwent a transplant after the 2018 heart transplant allocation change, pretransplant pulmonary hypertension, and increased total ischemic time as predictors of reduced DAOH365. CONCLUSIONS: In this analysis of patients undergoing orthotopic heart transplantation, there was no significant difference in DAOH365 in patients with prior MCS as a bridge to transplant compared to those without MCS. Incorporating days alive and out of the hospital into the pre-transplant evaluation may improve understanding and conceptualization of the post-transplantation patient experience and aid in shared decision-making with clinicians.

OBJECTIVE: Plasma D-dimer levels >0.5 mg/L are encountered in various conditions besides venous thromboembolism (VTE). Recent studies use them as a prognostic indicator for systemic and inflammatory diseases. The clinical significance of abnormal levels is unclear in osteomyelitis patients with baseline elevation. Our study reviews the occurrence and significance of >0.5 mg/L D-dimer levels in different types of osteomyelitis. PATIENTS AND METHODS: This study involved 125 individuals, out of which 94 were male and 31 were female. The patients were divided into two groups based on the results of bacterial culture testing. Group A comprised those who tested positive for bacterial culture, while group B included those who tested negative. Out of 68 samples tested, 56% were found to have Staphylococcus aureus. All 125 patients underwent blood testing, which included measuring the D-dimer levels, neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), lymphocyte to monocyte ratio (LMR), and MHR monocyte to high-density lipoprotein cholesterol (HDL-C) ratio in different types of osteomyelitis. The statistical analysis of these tests was carried out. RESULTS: Although there were no significant differences in white blood cell (WBC) count, Neutrophil count, Lymphocyte count, or erythrocyte sedimentation rate (ESR) as well as the NLR, PLR, LMR, MHR, HDL-C ratio. The C-reactive protein (CRP) levels were significantly higher in group A (26.13±50.30) than in group B (10.76±18.70) (p<0.05). D-dimer levels were elevated in 40.8% of patients with bacterial culture-positive osteomyelitis, negative culture osteomyelitis, implants with fractures, and no trauma osteomyelitis. No correlation was found between the increase in D-dimer levels and the presence of bacterial culture or implant-related osteomyelitis in patients. CONCLUSIONS: No significant correlation was found between D-dimers and osteomyelitis, including positive bacterial cultures, implant-related osteomyelitis, or osteomyelitis without trauma. However, 40% of the patients had higher D-dimer levels.
