Comparison of edoxaban and enoxaparin in a rat model of AlCl3-induced thrombosis of the superior sagittal sinus.

Cerebral sinus venous thrombosis (CSVT) is an uncommon disease that is usually treated with anticoagulation (heparin, low-molecular heparin, or vitamin K-antagonists). We compared treatment with edoxaban, an oral factor Xa-antagonist, that has not been approved in patients with CSVT, with enoxaparin, a well-established therapy, in a rat model of CSVT. Fifty male Wistar rats were randomized into 5 groups (10 animals each) and subjected to aluminum chloride (AlCl3)-induced thrombosis of the superior sagittal sinus (SSS) or sham procedure. Animals with thrombosis of the SSS were treated with edoxaban, enoxaparin, or placebo. Diagnostic workup included neurological examination, MRI imaging, MR-flow measurements of the SSS, and immunohistochemical staining. Neurological examination revealed no differences between treatment groups. Seven days after initial thrombosis, flow in the SSS was lower in the active treatment group as compared to sham-operated animals (p < 0.05). Flow in the SSS in the active treatment groups (edoxaban 1 h prior to thrombosis: 0.16 cm/s ± 0.06 cm/s; edoxaban 6 h after thrombosis: 0.13 cm/s ± 0.05 cm/s; enoxaparin: 0.13 cm/s ± 0.04 cm/s; placebo: 0.07 cm/s ± 0.02 cm/s) was higher as compared to placebo (p < 0.05), but there were no differences between the active treatment groups (p > 0.05). Immunohistochemical staining showed no differences in the actively treated animals. Edoxaban proved to be similar to enoxaparin in a model of experimental AlCl3-induced CSVT.

Transesophageal Echocardiography - Dysphagia Risk in Acute Stroke (TEDRAS): a prospective, blind, randomized and controlled clinical trial.

BACKGROUND AND PURPOSE: Dysphagia is common in acute stroke and leads to worse overall outcome. Transesophageal echocardiography (TEE) is used in the diagnostic evaluation of stroke with regard to its etiology and is a known cause of postoperative dysphagia in cardiac surgery. The prevalence of dysphagia in acute stroke patients undergoing TEE remains unknown. The aim of the Transesophageal Echocardiography - Dysphagia Risk in Acute Stroke (TEDRAS) study was to assess the influence of TEE on swallowing among patients who have experienced acute stroke. METHODS: The TEDRAS study was a prospective, blind, randomized, controlled trial that included two groups of patients with acute stroke. Simple unrestricted randomization was performed, and examiners were blinded to each other's results. Swallowing was tested using flexible endoscopic evaluation of swallowing (FEES) at three different time points in the intervention group (24 h before, immediately after and 24 h after TEE) and in the control group (FEES on three consecutive days and TEE earliest after the third FEES). Validated scales were used to assess dysphagia severity for all time points as primary outcome measures. RESULTS: A total of 34 patients were randomized: 19 to the intervention group and 15 to the control group. The key findings of the repeated-measures between-group comparisons were significant increases in the intervention group for the following dysphagia measures: (1) secretion severity score (immediately after TEE: P < 0.001; 24 h after TEE: P < 0.001) and (2) Penetration-Aspiration Scale score for saliva (immediately after TEE: P < 0.001; 24 h after TEE: P = 0.007), for small (immediately after TEE: P = 0.009) and large liquid boli (immediately after TEE: P = 0.009; 24 h after TEE: P = 0.025). CONCLUSION: The results indicate a negative influence of TEE on swallowing in acute stroke patients for at least 24 hours.

Management of malnutrition in geriatric trauma patients: results of a nationwide survey.

PURPOSE: Prevalence of malnutrition in geriatric trauma patients ranges between 30 and 50 % in Germany. Malnutrition is associated with impaired wound healing, a prolonged in-hospital stay, reduced post-traumatic mobility, as well as a higher mortality. Thus, detection and improvement of nutritional status could be a fundamental contribution in optimizing the treatment of these patients. METHODS: We sent a web-based questionnaire to 579 German hospitals with traumatological expertise, seeking information on the institutional care level, number of beds, use of nutritional assessments, and use of defined laboratory parameters for the detection of malnutrition. Furthermore, we focused on the presence and frequency of nutrition ward rounds on the intensive care unit. RESULTS: We received 151 answers. Nutritional status was analysed in one-third (N = 50). The half of these 50 clinics (54 %, N = 27) were using the body mass index (BMI), 20 % (N = 10) were using the nutritional risk screening (NRS), and 14 % (N = 7) used the mini nutritional assessment. 38 hospitals indicated a regular nutrition ward round; 63 % of them occurred daily, 13 % had a weekly frequency, and 24 % were on demand. Laboratory parameters were used inhomogeneously. Except for the more frequent use of the NRS (p = 0.026) in local trauma centres, we found no significant difference in the detection of malnutrition according to the care level. CONCLUSIONS: Although we know malnutrition is a frequent condition in geriatric patients, a minority of clinics considered it. The BMI and the NRS showed acceptance in practice; other parameters were used inhomogeneously. Although these findings may be limited in their significance, they indicate that the detection of malnutrition needs further investigation.

Evaluation of methoprene, temephos and Bacillus thuringiensis var. israelensis against Coquillettidia perturbans larvae in Minnesota.

Temephos, Bacillus thuringiensis var. israelensis (B.t.i.) and methoprene were tested for larval control of Coquillettidia perturbans. Neither temephos nor B.t.i. treatments at their maximum recommended dosages consistently reduced larval numbers. Larval emergencies were reduced 99% in test plots treated with experimental, controlled release methoprene briquets (Altosid SR-10). Breeding sites of Cq. perturbans in a 5,000 km2 area were treated using methoprene briquets in the 1984 season. Adult populations in a 7,700 km2 area were 2.5 times higher in untreated areas than treated areas. Methoprene can effectively control larval populations of Cq. perturbans.
