Review Meta Analysis
Factors predicting venous thromboembolism after spine surgery.
A meta-analysis was performed to explore predicted factors of venous thromboembolism (VTE) after surgery in the treatment for spine degeneration diseases. ⋯ Based on our meta-analysis, Asian patients, patients with walking disability preoperation, patients wearing elastic stocking, patients having undergone lumbar surgery, patients with a history of HT, and patients experiencing diabetes have a higher incidence of VTE after spine surgery.

Multicenter Study Comparative Study Observational Study
Management of ST-segment elevation myocardial infarction in predominantly rural central China: A retrospective observational study.
The degree of adherence to current guidelines for clinical management of ST-segment elevation myocardial infarction (STEMI) is known in developed countries and large Chinese cities, but in predominantly rural areas information is lacking. We assessed the application of early reperfusion therapy for STEMI in secondary and tertiary hospitals in Henan province in central China. Data were retrospectively collected from 5 secondary and 4 tertiary hospitals in Henan concerning STEMI patients treated from January 2011 to January 2012, including management strategy, delay time, and inhospital mortality. ⋯ Inhospital mortality was 5.8%, and similar between secondary and tertiary hospitals (6.0% vs 5.6%; P = 0.183). Two-thirds of STEMI patients did not receive early reperfusion, and tertiary hospitals mostly failed to take advantage of around-the-clock primary percutaneous coronary intervention. Actions such as referrals are warranted to shorten prehospital delay, and the concerns of patients and doctors regarding reperfusion risk should be addressed.

Bacterial cellulitis post-Cesarean section is rare. Negative pressure wound therapy (NPWT) is widely used in various medical specialities; its effectiveness in obstetrics however remains the topic of debate-used predominantly as an adjunct to secondary intention specific to high-risk patient groups. Its application in the treatment of actively infected wounds post-Cesarean is not well documented. Here, we document NPWT in the treatment of an unusually severe case of bacterial cellulitis with abdominal abscess postpartum. We provide a unique photographic timeline of wound progression following major surgical debridement, documenting the effectiveness of 2 different NPWT systems (RENASYS GO and PICO, Smith & Nephew). We report problems encountered using these NPWT systems and "ad-hoc" solutions to improve efficacy and patient experience.A 34-year-old primiparous Caucasian female with no prior history or risk factors for infection and a normal body mass index (BMI) presented with severe abdominal pain, swelling, and extensive abdominal redness 7 days postemergency Cesarean section. Examination revealed extensive cellulitis with associated abdominal abscess. Staphylococcus aureus was identified in wound exudates and extensive surgical debridement undertaken day 11 postnatally due to continued febrile episodes and clinical deterioration, despite aggressive intravenous antibiotic therapy. Occlusive NPWT dressings were applied for a period of 3 weeks before discharge, as well as a further 5 weeks postdischarge into the community.NPWT was well tolerated and efficacious in infection clearance and wound healing during bacterial cellulitis. Wound healing averaged 1 cm per week before NPWT withdrawal; cessation of NPWT before full wound closure resulted in significantly reduced healing rate, increased purulent discharges, and skin irritation, highlighting the efficacy of NPWT. Five-month follow-up in the clinic found the wound to be fully healed with no additional scarring beyond the boundaries of the original Cesarean incision. The patient was pleased with treatment outcomes, reporting no lasting pain or discomfort from the scar. ⋯ This report represents the first documented use of NPWT to aid healing of an actively infected, open wound following extensive surgical debridement 10 days post-Cesarean section, confirming both the efficacy and tolerability of NPWT for the treatment of severe bacterial cellulitis in obstetric debridement.

The type of postoperative cognitive decline after surgery under spinal anesthesia is unknown. We investigated the type of postoperative cognitive decline after total knee arthroplasty (TKA). Neuropsychological testing was conducted and the changes in cerebrospinal fluid (CSF) biomarkers after surgery were evaluated. ⋯ Our results suggest that frontal-executive function declined 1 week after TKA under spinal anesthesia. The CSF biomarker analysis indicated that TKA under regional anesthesia might not cause neuronal damage.

Observational Study
Risk of infection is associated more with drain duration than daily drainage volume in prosthesis-based breast reconstruction: A cohort study.
In prosthesis-based breast reconstruction, drains are used to prevent seroma formation and to reduce the risk of infection. However, prolonged drainage increases the risk of ascending infection. Although the volume often accepted for drain removal is ≤30 mL per day, the optimal timing to remove the drain for best clinical outcome remains controversial. ⋯ Breast weight also had a significant influence on risk of infection. Chemotherapy and drain size showed borderline effect on risk of infection whereas the last daily drainage volume was not associated with risk of infectionIn summary, our study revealed that drain duration, rather than the last daily drainage volume, significantly affects the infection rate in prosthesis-based breast reconstruction. We recommend that the drain is better removed no longer than 3 weeks postoperatively and can be removed as early as postoperative day 7, even when the drainage is over 30 mL in a 24-hour period.
