Role of Pre-Operative Nutrition Status on Surgical Site Infection After Posterior Lumbar Interbody Fusion: A Retrospective Study.

A retrospective case-control study to determine the role of pre-operative systemic and local nutritional factors on patients developing a surgical site infection (SSI) after posterior lumbar interbody fusion (PLIF). Surgical site infection after PLIF remains a substantial cause of morbidity. The literature demonstrates the prognosis of surgical patients is associated with pre-operative nutritional status that not only includes systemic nutritional factors, such as prognostic nutritional index (PNI), body mass index (BMI), and serum albumin, but also local nutritional factors, such as subcutaneous fat thickness at the surgical site, including absolute fat thickness and relative fat thickness.

Comparative transcriptome analysis provides insight into nitric oxide suppressing lignin accumulation of postharvest okra (Abelmoschus esculentus L.) during cold storage.

In plants, NO has been proved the function of improving abiotic stress resistance. However, the role of NO in the lignin metabolism of okra under cold stress has not been clarified. Here, histochemical staining and lignin content analysis showed that cold stress promoted the lignin accumulation of cold stored okra pods, and NO inhibited the lignin accumulation and delayed lignification process.

Posterior vertebral column resection for correction of thoracolumbar kyphosis after failed anterior instrumented fusion.

To explore the effectiveness of posterior vertebral column resection for failed thoracolumbar anterior instrumented fusion.Ten patients with anterior fusion with refractory pain, progressive neurological deficits, and kyphosis were recruited. Anterior removal of the implant and posterior vertebral column resection were performed.

Continuous Epidural Irrigation and Drainage Combined with Posterior Debridement and Posterior Lumbar Inter-Body Fusion for the Management of Single-Segment Lumbar Pyogenic Spondylodiscitis.

To observe the clinical curative effect of continuous epidural irrigation combined with posterior debridement and posterior lumbar inter-body fusion with instrumentation for the therapy of single-segment lumbar pyogenic spongdylodiscitis. From June 2010 to November 2013, surgical treatment was performed in 18 patients with pyogenic spondylodiscitis. The surgical indications were progressive biomechanical instability, epidural abscesses, deterioration of neurologic status, and intractable back pain.

Socioeconomic and Environmental Determinants to Preterm Birth in Tibetan Women: An Analysis Based on the Hierarchically Conceptual Frame.

Background: Preterm birth is a common cause of death in newborns and may result from many determinants, but evidence for the socioeconomic and environmental determinants of preterm birth in Tibetan women of childbearing age is limited. The aim of this study was to understand the current status of preterm birth in native Tibetan women and investigate the socioeconomic and environmental determinants.

Methods: Data were drawn from a cohort study which was conducted from August 2006 to August 2012 in rural Lhasa, Tibet, China.

Bronchogenic cyst of the conus medullaris with spinal cord tethering: a case report and review of the literature.

Bronchogenic cysts (BCs) are congenital malformations that originate from remnants of the primitive foregut. Intraspinal BCs, especially those of the conus medullaris are rare with only one case reported until now. To date, a bronchogenic cyst with spinal cord tethering has not been previously reported.

[Association between the distribution of feeding index and physical development of infants and young children aged 6-35 months in rural areas of Lhasa in 2010].

Objective: Using infant and child feeding index (ICFI) to evaluate the relationship between infant feeding and physical development indicators in rural areas of Lhasa.

Methods: In July and August 2010 in the rural areas of Lhasa, the multi-stage cluster random sampling method was adopted to select 540 Tibetan children who were between 6 to 35 months of age. There were 70, 79 and 391 cases in 6 to 8, 9 to 11 and 12 to 35-month-old group respectively.

Pedicle screw implantation in the thoracic and lumbar spine of 1-4-year-old children: evaluating the safety and accuracy by a computer tomography follow-up.

Study Design: This was a retrospective clinical study.

Objective: To evaluate the safety and accuracy of pedicle screw placement in very young children and to observe its influence on vertebral and spinal canal growth.

Summary Of Background Data: Although widely used, it is not known if pedicle screw fixation is safe and effective in very young children.

[Analysis on growth and malnutrition status of Tibetan children aged 0 to 35 months in rural Lhasa in 2010].

Objective: To understand the growth and malnutrition status of Tibetan children aged 0 to 35 months in rural Lhasa in 2010.

Methods: Cross-sectional study and multistage sampling design were used to randomly select sampling units. A total of 640 children were studied.

Application of an antibiotic crescent-shaped polymethylmethacrylate strut in thoracic vertebral tuberculosis.

Spinal tuberculosis accounts for up to 50% of all cases with musculoskeletal tuberculosis. In patients needing surgical treatment, the use of anterior instrumentation offers the theoretical advantage of more complete debridement and decompression, safer mobilization and reliable deformity correction. However, the placement of instrumentation in an infected area remains a matter of debate.

Effect of plant growth-promoting rhizobacteria (PGPRs) on plant growth, yield, and quality of tomato (Lycopersicon esculentum Mill.) under simulated seawater irrigation.

To determine the effects of three PGPRs on plant growth, yield, and quality of tomato under simulated seawater irrigation, a two consecutive seasons' field experiment was conducted in Yancheng Teachers University plot from April to June and August to October, 2011. The results showed that Erwinia persicinus RA2 containing ACC deaminase exhibited the best ability compared with Bacillus pumilus WP8 and Pseudomonas putida RBP1 which had no ACC deaminase activity to enhance marketable yields of fresh and dried fruits in tomato under simulated seawater irrigation especially under HS condition. B.

Application of a crescent-shaped PMMA strut in anterior spinal reconstruction of thoracolumbar and lumbar burst fractures: a new technique.

Material And Methods: Six patients suffering thoracolumbar and lumbar fracture using a crescent-shaped PMMA strut combined with fixation for reconstruction of the anterior spinal column.

Single-stage posterior instrumentation and anterior debridement for active tuberculosis of the thoracic and lumbar spine with kyphotic deformity.

Objective: The purpose of this study was to validate the efficacy and safety of single-stage posterior instrumentation and anterior debridement for treatment of active spinal tuberculosis with kyphotic deformity.

Cauda equina syndrome caused by a migrated bullet in dural sac.

Cauda equina syndrome (CES) is a serious neurological condition and the most common cause is a central disc herniation. Migration of a bullet down the spinal canal is uncommon. In this report, the authors present an unusual case of cauda equina syndrome caused by a migrated bullet in dural sac.
