Factor-guided diagnosis of coagulopathy associated with coumarin-contaminated synthetic cannabinoids.

Contamination of synthetic cannabinoids with toxic coumarin derivatives known as superwarfarins can induce a persistent coagulopathy. In comparison to warfarin, these derivatives have prolonged half-lives and laboratory assays for detection are not readily available in clinical practice. To our knowledge, factor-guided diagnosis of coagulopathy secondary to coumarin-contaminated synthetic cannabinoids has not been described previously. Our case report details a young adult who presented to the hospital with an acute elevation in INR without any reported past medical history or illicit substance use. Factor levels were obtained and resulted quickly revealing deficiencies in factors II, VII, IX, and X, which led to a possible diagnosis of coagulopathy secondary to coumarin-contaminated synthetic cannabinoids. Upon further questioning, the patient admitted to use of synthetic cannabinoids. A bromadiolone assay was sent for testing, which resulted positive after patient discharge. Toxic coumarin derivative assays are not immediately available for reference. Given the patient's confirmed synthetic cannabinoid consumption and the possibility of coagulopathy from coumarin-contamination, factor levels served as a guide for diagnosis and treatment prior to the confirmatory assay. Obtaining factor levels in patients with an unexplained coagulopathy and suspected cannabis or synthetic cannabinoid use may aid clinicians in a more prompt diagnosis and treatment.

Comparison of three antimicrobial strategies in diabetic foot infections post-amputation.

BACKGROUND: The 2012 Infectious Disease Society of America (IDSA) guidelines recommend antimicrobial treatment of diabetic foot infections (DFIs) post-amputation, but the optimal route and duration are poorly defined. OBJECTIVE: The objective of this study was to determine whether the selection of a specific antimicrobial treatment modality affected hospital and patient outcomes. METHODS: This was a retrospective review of hospital admissions of adults admitted to ourhealthcare system with a primary diagnosis of DFIs post-amputation. The groups were separated into patients who received intravenous antimicrobials (IV), oral antimicrobials (PO), or no antimicrobials (NA). Outcomes included average length of stay among others. RESULTS: Of the 200 patients screened, 120 patients were included (IV n = 72; PO n = 20; NA n = 28). No statistically significant differences were identified in average LOS (IV = 9.97 ± 5.85, PO = 8.83 ± 7.37, NA = 9.33 ± 5.91 days; p = 0.73). However, post-operative (post-op) LOS was significantly shorter in the PO group (PO = 3.43 ± 2.56, IV = 7.34 ± 5.95, NA = 5.81 ± 4.18 days; p = 0.0001). CONCLUSION: The results of our study indicate that a PO antimicrobial treatment strategy post amputation for DFIs has the potential to decrease post-op LOS without increasing the risk of readmission. Based on the results of our study, we feel consideration should be given to transition to oral antimicrobials soon after amputation to facilitate discharge and decrease the utilization of intravenous antimicrobials.

End-Stage Renal Disease Increases Rates of Adverse Glucose Events When Treating Diabetic Ketoacidosis or Hyperosmolar Hyperglycemic State.

IN BRIEF Treatment guidelines for diabetic emergencies are well described in patients with normal to moderately impaired kidney function. However, management of patients with end-stage renal disease (ESRD) is an ongoing challenge. This article describes a retrospective study comparing the rates of adverse glucose events (defined as hypoglycemia or a decrease in glucose >200 mg/dL/h) between patients with ESRD and those with normal kidney function who were admitted with diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS). These results indicate that current treatment approaches to DKA or HHS in patients with ESRD are suboptimal and require further evaluation.

The impact of parental history of type 2 diabetes on hyperinsulinemia and insulin resistance in subjects from central Mexico.

AIMS: Hyperinsulinemia and insulin resistance are both associated with the development of Type 2 Diabetes and other pathologies; however, the influence of parental history of Type 2 diabetes (PH-T2D) has yet to be investigated. Therefore, this study was conducted to determine the effect of PH-T2D has on the risk of developing hyperinsulinemia and IR. MATERIALS AND METHODS: 1092 subjects (703 non-pregnant females and 389 males) were enrolled for a cross-sectional study. Clinical and biochemical parameters were collected. Subjects were allocated according to their PH-T2D: no parents, one parent, or both parents. Insulin resistance was calculated using the HOMA1 equation (HOMA1-IR). Logistic regression was used to determine the association (odds ratio) between PH-T2D and hyperinsulinemia or insulin resistance. RESULTS: Increasing degrees of PH-T2D were associated with significant increases in fasting plasma glucose, insulin, and HOMA1-IR (p <0.05). Subjects having one or both parents were associated with an increase risk of developing hyperinsulinemia (odds ratio=1.53, 95%CI: 1.12-2.09, and odds ratio=1.92, 95%CI: 1.21-3.06, respectively) and insulin resistance (odds ratio=1.47, 95%CI: 1.08-2.00 and odds ratio=1.77, 95%CI: 1.09-2.87, respectively), when adjusting for age, sex, BMI, fasting plasma glucose, and triglycerides. CONCLUSION: The presences of PH-T2D significantly increased the risk of developing hyperinsulinemia and insulin resistance.
