Comparative StudyLate venous thromboembolism prophylaxis after craniotomy in acute traumatic brain injury.
The objective of this study is to compare rates of venous thromboembolism (VTE) in patients who receive enoxaparin prophylaxis compared with no enoxaparin prophylaxis after craniotomy for traumatic brain injury (TBI). This retrospective cohort evaluated all trauma patients admitted to a Level I trauma center from January 2006 to December 2011 who received craniotomy after acute TBI. Patients were excluded if developed VTE before administration of enoxaparin or they died within the first 72 hours of hospital admission. ⋯ Late enoxaparin prophylaxis did not demonstrate a protective effect for VTE. Given the overall low event rate, the administration of pharmacologic prophylaxis against VTE late in the treatment course may not be routinely warranted after craniotomy for acute TBI. Further investigation with early administration of enoxaparin is needed.

Changes in fecal and colonic mucosal microbiota of patients with refractory constipation after a subtotal colectomy.
The purpose of this study was to investigate the changes in gut microbiota of patients with refractory constipation 6 months after a subtotal colectomy. Feces and mucosal samples of five healthy volunteers and 17 patients with refractory constipation before and six months after subtotal colectomy were collected. Denaturing gradient gel electrophoresis (DGGE) and polymerase chain reaction techniques were used for quantitative analysis of main bacterial groups and archeal methanogens. ⋯ The number of methanogens in the mucosa was decreased in preoperative patients but returned to normal levels postoperatively. In conclusion, although there was no difference in the structure of the predominant bacteria between refractory constipated patients and healthy control subjects, the number of probiotics (Bifidobacteria and Lactobacilli) was significantly lower in refractory constipated patients. However, subtotal colectomy can significantly normalize the number of intestinal flora.

Outcomes in traumatic brain injury for patients presenting on antiplatelet therapy.
An increasing number of patients are presenting to trauma units with head injuries on antiplatelet therapy (APT). The influence of APT on these patients is poorly defined. This study examines the outcomes of patients on APT presenting to the hospital with blunt head trauma (BHT). ⋯ Subgroup analysis revealed that patients with ISS 20 or greater on APT had increased in-hospital mortality (OR, 2.34; 95% CI, 1.03 to 5.31). LOS greater than 14 days was more likely in the APT group than those in the non-APT group (OR, 1.85; 95% CI, 1.09 to 3.12). The effects of antiplatelet therapy in patients with BHT aged 40 years and older showed no difference in ICH, NI, and in-hospital mortality.

Does immediate tissue expander placement increase immediate postoperative complications in patients with breast cancer?
The objectives of this study were to evaluate 1) the rate of immediate breast reconstruction; 2) the frequency of immediate tissue expander placement; and 3) to compare perioperative outcomes in patients who underwent breast reconstruction after mastectomy for breast cancer with immediate tissue expander placement (TE) with those with no reconstruction (NR). Using the Nationwide Inpatient Sample database, we examined the clinical data of patients with breast cancer who underwent mastectomy with or without immediate TE from 2006 to 2010 in the United States. A total of 344,253 patients with breast cancer underwent mastectomy in this period in the United States. ⋯ The rate of immediate reconstruction is 31 per cent. TE alone is the most common type of immediate reconstruction (57%). There is a lower complication rate for the patients who underwent immediate TE versus the no-reconstruction cohort.
